//usr/share/doc/libnih-1.0.1/ChangeLog

2010-02-04  Scott James Remnant  <scott@netsplit.com>

* NEWS: Release 1.0.1

* nih/logging.c (__abort_msg): Make a weak symbol reference.
	(nih_log_abort_message): Check whether __abort_msg has an address
	before saving.
	* nih/tests/test_logging.c (__abort_msg): Make a weak symbol reference.
	(test_log_message): Skip __abort_msg tests if there is no address
	for it.

2010-02-03  Scott James Remnant  <scott@netsplit.com>

* nih/libnih.ver: Add missing export for __nih_* so you can build
	test cases; not bumping the library age here since this isn't an API
	change but a bug.

* nih-dbus-tool/Makefile.am ($(com_netsplit_Nih_Test_object_OUTPUTS)):
	($(com_netsplit_Nih_Test_proxy_OUTPUTS)): Make compatible with
	am-silent-rules by using $(AM_V_GEN) and combining the mkdir and
	nih-dbus-tool lines.

* configure.ac: Bump copyright year to 2010.
	* NEWS: Begin new release.

2009-11-29  Scott James Remnant  <scott@netsplit.com>

* configure.ac (AM_INIT_AUTOMAKE): Drop dist-bzip2, since we don't
	use them.

* configure.ac: Bump version to 1.0.1

2009-11-28  Scott James Remnant  <scott@netsplit.com>

* NEWS: Release 1.0.0

* nih-dbus-tool/main.c (source_file_path, header_file_path): Use a
	not reached assertion rather than an initial one, to avoid gcc
	warnings.
	* nih/tests/test_string.c (test_array_addp),
	* nih/tests/test_logging.c (test_log_message): Add a couple more
	initialisations for gcc, found with -O2

* TODO: Update.

* nih/tests/test_error.c (test_raise_error, test_pop_context): Also
	unlink core.PID form of core file, and unlink a valgrind core of the
	same name as well while we're in there.
	* nih/tests/test_child.c (test_poll): Do the same here, except it
	turns out that under valgrind we might still have NIH_CHILD_KILLED
	but a core file - always clean up core files anyway.

* nih/libnih.supp, nih-dbus/libnih-dbus.supp: Valgrind got a whole
	bunch more strict in the 3.5 release.  That's a good thing because
	we catch more errors, but it means it's somewhat picker about things
	like our reference allocations.  Redo the suppressions against 3.5,
	taking an opportunity to clean up the files and insert documentation
	as to why they are there.
	* nih/tests/test_signal.c (test_poll): The two signal structures
	allocated in this function were not being freed at the end.
	* nih/tests/test_watch.c (test_reader): On termination of this test
	we were not freeing the last path copied.
	* nih-dbus/tests/test_dbus_connection.c (test_connect, test_bus)
	(test_setup): Free signal handlers before exiting the child,
	unlike other test cases we can't make these children of any other
	object since we don't actually have one!
	* nih-dbus-tool/tests/test_annotation.c (test_start_tag)
	(test_end_tag): Missing call to discard the NULL reference from the
	various objects after pushing onto the stack.
	* nih-dbus-tool/tests/test_parse.c (test_stack_push): Thanks to
	the updated valgrind, I can now see that this test case wasn't updated
	for the new nih_alloc() behaviour.  We now need to free the object
	even after it's been referenced, because it still has our NULL
	reference.
	(test_start_tag, test_end_tag): Also need to discard the NULL
	reference in each of these cases.

2009-11-24  Scott James Remnant  <scott@netsplit.com>

* nih/logging.c (nih_log_message): Split the abort message saving
	out into its own function.
	(nih_log_abort_message): This makes it easier to suppress.
	* nih/libnih.supp: Add suppressions.

* NEWS: Update.

* nih/libnih.supp: Add new tmpfile suppression

* nih-dbus-tool/interface.c (interface_proxy_get_all_function),
	* nih-dbus-tool/method.c (method_proxy_function),
	* nih-dbus-tool/property.c (property_proxy_get_function)
	(property_proxy_set_function): The dbus_connection_send_with_reply()
	function can return TRUE without setting a pending_call in the case
	of a non-connected connection.  Convert this into the
	DBUS_ERROR_DISCONNECTED error to match send_with_reply_and_block

	(test_set_struct_array_sync, test_get_dict_entry_array_sync)
	(test_set_dict_entry_array_sync, test_get_all_sync):
	Add test cases for a sync() function on a disconnected connection,
	which should return the same error internally inside D-Bus.

* nih-dbus-tool/tests/test_com.netsplit.Nih.Test_proxy.c: These
	tests weren't passing under valgrind, because I got lazy and gave
	up.  Most of the reason was that the main signal handler wasn't
	freed; fix that by attaching the signal to the D-Bus object.

* nih/test_process.h (TEST_CHILD, TEST_CHILD_WAIT): Flush standard
	output and error before forking, to avoid the typical strange
	buffering issues when piping to less.

* nih/alloc.c (NihAllocCtx): The recent alignment changes mean
	there's always 4 bytes of spare space in this structure, use those
	to remember the allocation size rather than relying on malloc()
	to do it.  This makes us more portable to alternative (and debugging)
	malloc implementations.
	(nih_alloc, nih_realloc): Update the size field
	(nih_alloc_size): Just return the size field.

* TODO: Update.

2009-11-21  Scott James Remnant  <scott@netsplit.com>

* nih/option.c: Add a note that --debug is deliberately hidden.

* nih/macros.h (NIH_ALIGN_SIZE): Fix rounding to be twice size
	of size_t, or alignment of long long - which is what we decided
	in the bug.
	* nih/alloc.c (NIH_ALLOC_SIZE): Formatting.

* nih/Makefile.am (libnih_la_LDFLAGS): Bump version
	* nih-dbus/Makefile.am (libnih_dbus_la_LDFLAGS): Bump version

* configure.ac (AC_PRERQ): Update to 2.62
	(AM_INIT_AUTOMAKE): Update to 1.11, add color-tests and silent-rules
	to the options
	(AM_SILENT_RULES): Explicitly make silent rules the default
	(AM_MAINTAINER_MODE): Add, but with "enable" as the default, so
	distributions may turn it off with --disable-maintainer-mode
	(AM_GNU_GETTEXT_VERSION): Update to 0.17
	* HACKING: Update requirements; document that we support the
	standard options.

2009-11-21  John Cater  <katre50@gmail.com>

* nih/macros.h (NIH_ALIGN_SIZE): Add macro to guess at the maximum
	alignment of a type
	* nih/alloc.c (NIH_ALLOC_SIZE): Define the size of the context
	based off its size and the maximum alignment macro, thus hopefully
	ensuring the following pointer is generically aligned
	(NIH_ALLOC_CTX, NIH_ALLOC_PTR): Redefine based on NIH_ALLOC_SIZE
	(nih_alloc, nih_realloc, nih_alloc_size): Use NIH_ALLOC_SIZE
	instead of sizeof (NihAllocCtx)

2009-11-21  Scott James Remnant  <scott@netsplit.com>

* NEWS: Update

* nih-dbus-tool/main.c: Add option to supply the package name
	and store in a global variable for the output code to access.
	* nih-dbus-tool/output.c (output_preamble): Use the supplied package
	name in preference to "libnih" when generating preamble comments.
	(output_sentinel): Use the supplied package name in preference to
	"libnih" when generating header sentinels.
	* nih-dbus-tool/output.h: Add variable declaration
	* m4/Makefile.am (nih_dbus_tool_LDADD): Turns out that this doesn't
	link with libnih-dbus at all

* nihify: Remove the script to copy into other source directories

* nih/libnih.ver, nih-dbus/libnih-dbus.ver: Update versions

* nih-dbus-tool/Makefile.am (bin_PROGRAMS): Always install the tool
	(dist_man_MANS): Always install the manual page
	(EXTRA_DIST): We don't need to distribute the manual page with this
	now

* nih/libnih.pc.in, nih-dbus/libnih-dbus.pc.in: Source to pkg-config
	data files
	* configure.ac: Generate the actual pkg-config files from the sources
	* nih/Makefile.am (lib_LTLIBRARIES): Always install libnih.la
	(include_HEADERS): Always install the header files
	(pkgconfig_DATA): Install the pkg-config file
	(EXTRA_DIST): Distribute the source to it
	* nih-dbus/Makefile.am (lib_LTLIBRARIES): Always install libnih-dbus.la
	(include_HEADERS): Always install the header files
	(pkgconfig_DATA): Install the pkg-config file
	(EXTRA_DIST): Distribute the source to it

* Makefile.am: Always build libnih-dbus and nih-dbus-tool

* m4/misc.m4, m4/compiler.m4, m4/linker.m4: Merge together into
	a single libnih.m4 file for easier aclocal inclusion.
	* m4/libnih.m4 (NIH_INIT): Drop this macro, libnih shouldn't need
	software to call any special macros other than the ones they
	probably need anyway.
	* m4/libs.m4: Drop this source and the NIH_LIB_DBUS macro, since
	we'll always build this
	* m4/Makefile.am: Unconditionally install the new macro file
	* configure.ac: Replace NIH_INIT with the bits we actually want to
	check for here.

* README: Remove the usage instructions, since this is going to
	be an ordinary shared library; rewrite the Dependencies section
	language to be better; add a Cross-compiling section.

* configure.ac: Since this library is now being used in several
	places, it's time to start caring about API and stop compiling it
	statically into things.  Bump version to 1.0.0.  Bug fixes without
	any API changes will be named 1.0.x; backwards compatible API
	changes 1.x.0, etc.
	* NEWS: Bump version to 1.0.0
	* TODO: Update with missing bits for 1.0 and plans for 1.1/2.0

2009-10-03  Scott James Remnant  <scott@netsplit.com>

* m4/libs.m4 (NIH_LIB_DBUS): Allow an external nih-dbus-tool to
	be used by setting NIH_DBUS_TOOL when calling configure; when
	cross-compiling, if this is not set, look for it in the PATH and
	warn if we fall back to using our built copy.
	* nih-dbus-tool/Makefile.am ($(com_netsplit_Nih_Test_object_OUTPUTS)): 
	($(com_netsplit_Nih_Test_proxy_OUTPUTS)): Use an externally built
	nih-dbus-tool for the tests if given, not strictly right but the
	best we can do when cross-compiling (when we probably won't run
	"make check" anyway)

* nih/file.c (nih_dir_walk_sort): Add static function to replace
	alphasort() which we can't call anymore.  It would be deeply ironic
	to bitch about glibc breaking API in the libnih changelog.
	(nih_dir_walk_scan): Replace alphasort() with nih_dir_walk_sort()

2009-08-11  Johan Kiviniemi  <johan@kiviniemi.name>

* nih/logging.c: Expose the glibc-internal __abort_msg symbol
	so that we can set it.
	(nih_log_message): Save a copy of any fatal or higher log message
	into this variable; assuming that abort() is the next function call
	as is the case for nih_assert()

2009-08-11  Scott James Remnant  <scott@netsplit.com>

* nih/test_alloc.h (TEST_ALLOC_NOT_PARENT): Add the opposite test
	for a known parent, making sure that something is not a parent.

2009-08-04  Scott James Remnant  <scott@netsplit.com>

* nih/tests/test_alloc.c (test_ref, test_unref): Add tests for
	multiple identical parents.
	* nih/alloc.h: Document that we specifically permit multiple
	references between two objects.

* configure.ac: 0.4.0 is a bit far, and the nih_alloc() changes are
	largely minor in effect outside the library; let's call this 0.3.5
	* NEWS: Change version

* nih-dbus-tool/node.c (node_start_tag): Make node object local.
	(node_end_tag): Replace use of nih_unref_only with a simple
	nih_ref()/nih_unref() pair

	local.

	object local.
	* nih-dbus-tool/tests/test_type.c (test_of): Replace
	TEST_ALLOC_ORPHAN(ptr) with TEST_ALLOC_PARENT(ptr, NULL)

	TEST_ALLOC_ORPHAN(ptr) with TEST_ALLOC_PARENT(ptr, NULL)
	* nih-dbus-tool/tests/test_node.c (test_end_tag): 
	Replace TEST_ALLOC_ORPHAN(ptr) with TEST_ALLOC_PARENT(ptr, NULL)

	(test_end_tag): Discard stack objects after pushing
	* nih-dbus-tool/tests/test_argument.c (test_start_tag)
	(test_end_tag): Discard stack objects after pushing

* nih/io.c (nih_io_read_message): Replace use of nih_unref_only
	with a simple nih_ref()/nih_unref() pair
	(nih_io_write): Use nih_local for the message, we either reference
	it when we send or we throw it away on returning.
	* nih/tests/test_io.c (test_watcher): After sending the message
	we need to discard it, it's only referenced not stolen now.
	(test_read_message): Replace TEST_ALLOC_ORPHAN(msg) with
	TEST_ALLOC_PARENT(msg, NULL)

* nih/tests/test_string.c (test_sprintf, test_vsprintf)
	(test_strdup, test_strndup): Replace TEST_ALLOC_ORPHAN(ptr)
	checks with TEST_ALLOC_PARENT(ptr, NULL)
	(test_array_addp): Fix bad uses of TEST_ALLOC_FAIL on data
	allocated outside of the loop, necessary now that the pointer
	won't be "stolen" by the function merely referenced

* nih/alloc.c (nih_alloc_ref_new): Allow parent to be NULL, when
	it is we store NULL in ref->parent and leave the children_entry
	as an empty list node.
	(NIH_ALLOC_CTX): Context for a NULL pointer is NULL
	(nih_alloc): Always allocate a reference, even when the parent is
	NULL creating a NULL ref
	(nih_discard): Lookup a NULL reference and free that before checking
	for existing references.
	(nih_ref, nih_unref, nih_alloc_ref_lookup): Allow parent to be NULL
	(nih_unref_only): We don't need this function anymore so drop
	(nih_alloc_parent): Since NULL can be a parent, this now looks
	that up - there's no function for "has a parent"
	* nih/alloc.h: Remove nih_unref_only prototype, update documentation
	* nih/test_alloc.h (TEST_ALLOC_PARENT): Update documentation to
	reflect that NULL is valid again
	(TEST_ALLOC_ORPHAN): Drop this macro.

	Replace TEST_ALLOC_ORPHAN checks with TEST_ALLOC_PARENT (ptr, NULL)
	(test_ref): Make sure that the NULL reference is not removed by
	adding another; add new test for adding a new NULL reference.

2009-07-22  Michael Biebl  <mbiebl@gmail.com>

* nih-dbus-tool/Makefile.am (dist_man_MANS): Don't install the
	manpages unless INSTALL_NIH, take care to make sure they're still
	distributed.

	parent argument from calls to nih_dbus_proxy_connect.  Add test

	of the proxy.

	case for connecting to a signal by well-known name, rather than
	just unique name

	* nih-dbus-tool/tests/expected/test_output_proxy_standard.c,
	* nih-dbus-tool/tests/expected/test_output_object_standard.c: 
	Delete from the expected output as well.

* nih-dbus-tool/main.c: Add a --default-interface argument that

	the symbol annotation to be empty again.
	(interface_end_tag): Which means that the symbol can never be
	empty when we get to here.

	name using symbol_typedef() rather than expecting type_of() to do

	changes are enough to warrant it

* nih/tests/test_error.c (test_pop_context): Initialise pid to avoid
	gcc issue where it believes the value can be uninitialised
	(test_raise_error): Initialise errors and pid.
	* nih-dbus/tests/test_dbus_connection.c (test_connect): Initialise

	* nih-dbus-tool/tests/test_argument.c (test_start_tag): Another ret
	* nih-dbus-tool/tests/test_annotation.c (test_start_tag): Yet another
	* nih-dbus-tool/tests/test_com.netsplit.Nih.Test_proxy.c: Even more
	in this one.

* nih-dbus-tool/method.c (method_object_function): Don't translate
	the string we return to the caller.
	* nih-dbus-tool/property.c (property_object_set_function): Likewise
	don't translate.

	* nih-dbus-tool/tests/test_com.netsplit.Nih.Test_object.c: Too many
	to count in this source file

* nih-dbus-tool/Makefile.am (test_com_netsplit_Nih_Test_object_SOURCES)
	(test_com_netsplit_Nih_Test_proxy_SOURCES): Finally decided that we're
	not going to ship these built sources, we'd just regenerate them every
	build anyway because nih-dbus-tool will have changed.  Make them
	nodist.
	(AM_CPPFLAGS): Which means we also need to include files from the
	build directory, as well as the source directory
	(BUILT_SOURCES): Change explanation of why it's in built sources
	(CLEANFILES): Clean after build.

* nih/tests/test_error.c (test_raise_error, test_pop_context): Unlink
	the core file after the assert tests.

* nih-dbus-tool/tests/com.netsplit.Nih.Test_impl.c,
	* nih-dbus-tool/tests/test_com.netsplit.Nih.Test_object.c,
	* nih-dbus-tool/tests/test_com.netsplit.Nih.Test_proxy.c: #include
	quoted paths will only look in the source directory or current
	working directory, for out of tree builds the current working
	directory won't contain the header so we need to prefix with tests/
	so we can lookup from the source directory
	* nih-dbus-tool/tests/marshal_factory.c,
	* nih-dbus-tool/tests/demarshal_factory.c,
	* nih-dbus-tool/tests/method_factory.c,

	prefix includes with tests/

* nih/tests/test_error.c (test_raise_error, test_pop_context):
	Make sure we don't expect the filename to be always relative,
	e.g. out-of-tree builds.

2009-06-16  Scott James Remnant  <scott@netsplit.com>

* nih-dbus-tool/marshal.c (marshal_array, marshal_struct): In the
	array of structures situation, we can't just close the container
	because it's not been completed - instead we use the new abandon
	function to free the resources while hosing the message.
	* nih-dbus-tool/property.c (property_object_get_function)
	(property_proxy_set_function, property_proxy_set_sync_function):
	Likewise abandon the variant container, strictly speaking probably
	not required but worthwhile for consistenc
	* nih-dbus-tool/tests/test_marshal.c (test_marshal): Update the
	output checks to match
	* nih-dbus-tool/tests/test_method.c (test_object_function)
	(test_proxy_function, test_proxy_sync_function): More output updates

	(test_proxy_set_function, test_proxy_set_sync_function): Yet more
	* nih-dbus-tool/tests/test_node.c (test_object_functions)
	(test_proxy_functions): More output updates.
	* nih-dbus-tool/tests/test_output.c (test_output): Also update the
	top-level output

* nih-dbus-tool/tests/com.netsplit.Nih.Test_impl.c: Update the
	property functions to raise the no memory error where appropriate,
	also include code to return D-Bus and generic errors for testing.
	* nih-dbus-tool/tests/test_com.netsplit.Nih.Test_object.c (test_get_byte)
	(test_get_boolean, test_get_int16, test_get_uint16)

	(test_get_signature, test_get_int32_array, test_get_str_array)
	(test_get_int32_array_array): Add tests for the get function returning
	an D-Bus error and a generic error.
	* nih-dbus-tool/tests/test_com.netsplit.Nih.Test_proxy.c (test_get_byte)
	(test_get_boolean, test_get_int16, test_get_uint16, test_get_int32)
	(test_get_uint32, test_get_int64, test_get_uint64, test_get_double)
	(test_get_string, test_get_object_path, test_get_signature)
	(test_get_int32_array, test_get_int32_array_array): Add D-Bus error
	and generic error test cases to the async functions, making sure that
	the error handler is raised.
	(test_get_byte_sync, test_get_boolean_sync, test_get_int16_sync)
	(test_get_uint16_sync, test_get_int32_sync)
	(test_get_uint32_sync, test_get_int64_sync)
	(test_get_uint64_sync, test_get_double_sync, test_get_string_sync)
	(test_get_object_path_sync, test_get_signature_sync)
	(test_get_int32_array_sync, test_get_str_array_sync)
	(test_get_int32_array_array_sync): Also add D-Bus and generic error
	test cases to the sync functions, which are slightly harder to test
	because of the need for a separate server process; still, this tests
	the error return code.

* nih-dbus-tool/tests/test_node.c (test_object_functions): Update the
	output tests to expect the error raises.
	* nih-dbus-tool/tests/test_output.c (test_output): Update the output
	tests to match as well.

* nih-dbus-tool/property.c (property_object_get_function): Raise the
	no memory error when we return.
	* nih-dbus-tool/tests/test_property.c (test_object_get_function): Make
	sure that the output matches, and test the generated function with
	normal output, out of memory, dbus error and generic error returns.

* nih-dbus/dbus_object.c (nih_dbus_object_property_get): It makes
	sense to be able to return an error when getting a property, at the
	very least it might be a PolicyKit authorisation error.
	(nih_dbus_object_property_get_all): If we get an error while getting
	any property, we have to return that error to the user, such is the
	manner in which D-Bus messages have to be built.
	* nih-dbus/tests/test_dbus_object.c (test_object_property_get):
	Update function to test for property getter functions returning
	errors.
	(test_object_property_get_all): Include a couple of test cases
	here too.

* TODO (dbus): Update on no_reply, still not completely clear what
	we should do with this annotation as the results are surprising

* nih-dbus-tool/method.c (method_end_tag): Ignore the NoReply
	annotation if the method has output arguments; ignore the Async
	annotation if the method is NoReply.
	* nih-dbus-tool/tests/test_method.c (test_end_tag): Make sure the
	annotations are amended and warnings emitted as appropriate.

* nih-dbus-tool/node.c (node_object_functions): Don't generate reply
	functions for non-async method implementations
	* nih-dbus-tool/tests/test_node.c (test_object_functions): Make the
	peek method async so that's the only one that should have a reply
	function.  Also add an output value to another method to check
	ordinary return values.
	* nih-dbus-tool/tests/test_output.c (test_output): Apply the same
	changes to this test as well.

* nih-dbus-tool/tests/test_com.netsplit.Nih.Test_proxy.c: Turns out
	I was using the wrong timeout value everywhere, this is why macros are
	useful -- replace the wrong "0" with NIH_DBUS_TIMEOUT_DEFAULT

* nih-dbus/dbus_proxy.h (NIH_DBUS_TIMEOUT_DEFAULT)
	(NIH_DBUS_TIMEOUT_NEVER): Add macros so we don't have to remember
	what the timeout magic numbers are

* nih-dbus-tool/tests/test_com.netsplit.Nih.Test_object.c: Use
	TEST_FUNCTION with proper function names instead of TEST_GROUP

2009-06-15  Scott James Remnant  <scott@netsplit.com>

* nih-dbus-tool/tests/com.netsplit.Nih.Test_impl.h,
	* nih-dbus-tool/tests/com.netsplit.Nih.Test_impl.c, 
	* nih-dbus-tool/tests/test_com.netsplit.Nih.Test_object.c,
	* nih-dbus-tool/tests/test_com.netsplit.Nih.Test_proxy.c: Completely
	rewrite these tests using TEST_DBUS, making sure we test as much of the
	newly generated code as possible.

* nih-dbus-tool/tests/com.netsplit.Nih.Test.xml: Various slight
	updates to better test the newer code; add arrays of arrays to the
	tests; rename "data" to "value" to avoid clash with data argument;
	remove the glue we won't use it anymore.

* nih-dbus-tool/Makefile.am ($(com_netsplit_Nih_Test_proxy_OUTPUTS)):
	Use "proxy" as the prefix again, "your" just looks silly.

* nih-dbus-tool/type.c (type_strcat_assert): And now the other
	corner case we found, size arrays can be NULL if the first element
	of the array is NULL.
	* nih-dbus-tool/tests/test_type.c (test_strcat_assert): Add tests
	* nih-dbus-tool/method.c (method_reply_function)
	(method_proxy_function, method_proxy_sync_function),
	* nih-dbus-tool/signal.c (signal_object_function),
	* nih-dbus-tool/property.c (property_proxy_set_function)
	(property_proxy_set_sync_function): Think-o, we can't look at the
	previous iterated we have to look at the last function argument

* nih-dbus-tool/type.c (type_strcat_assert): We're starting to get
	a lot of corner cases in that simple assert block, separate it out
	so we don't have to repeatedly get it wrong.
	* nih-dbus-tool/type.h: Add prototype
	* nih-dbus-tool/tests/test_type.c (test_strcat_assert): The all
	important tests.
	* nih-dbus-tool/method.c (method_reply_function)
	(method_proxy_function, method_proxy_sync_function): Use the new
	function.
	* nih-dbus-tool/signal.c (signal_object_function): Likewise.
	* nih-dbus-tool/property.c (property_proxy_set_function)
	(property_proxy_set_sync_function): Likewise.

* nih-dbus-tool/method.c (method_reply_function)
	(method_proxy_function, method_proxy_sync_function): Input array
	arguments of basic types (those with a size_t argument following)
	may be NULL if that size_t argument is zero.  Check for this when

	to attempt to setup the watch, timeout and wake-up functions each
	time through nih_dbus_setup() so it can be called in a loop in
	cases of out-of-memory so do this first before setting the main
	loop function, and unwind in case of error.
	(nih_dbus_watch_toggled): D-Bus could try and change the flags
	with a toggle?

* nih-dbus/dbus_connection.h (NihDBusConnectHandler): Add missing

* nih-dbus/dbus_connection.c (nih_dbus_connect, nih_dbus_bus)
	(nih_dbus_server): Return ENOMEM raised on insufficient memory
	rather than the D-Bus equivalent; we don't just convert these
	everywhere because sometimes we want to know that it's the
	remote side that's out of memory and we don't want to use ENOMEM
	for that.

* nih-dbus/tests/test_dbus_connection.c: Various cleanup fixes,
	making sure we unref everything that we use.  Increase timeout
	for method calls since things get slower when under valgrind.

	Push an error context while calling the handler.
	(nih_dbus_new_connection): Push an error context while calling
	the handler.

* nih/timer.c (nih_timer_poll): The timer callback can free the
	timer, so we need to adjust the due time before we call it.  In
	the case of timeouts, we hold a reference while calling and
	always free after returning.  Also push an error context during
	it so we don't leak errors.

	TEST_ALLOC_FAIL, even the ones testing for errors.  To get around
	situations where some allocations may be repeated, but others will
	fail, check the return value to see which happened.

* nih-dbus/dbus_object.c (nih_dbus_object_message): We don't need

2009-01-29  Scott James Remnant  <scott@netsplit.com>

* nih-dbus/tests/test_com.netsplit.Nih.Test_proxy.c (test_method_dispatch): 
	Fix the test case to not compare a void * with strcmp

2008-01-29  Casey Dahlin  <cdahlin@redhat.com>

* nih/nih_dbus_tool.py (Method.asyncDispatchPrototype): Prototype for
	new asynchronous dispatch function, explained below.
	(Method.asyncDispatchFunction): The asynchronous dispatch function
	takes a proxy, the arguments to the given method, a callback and an
	"errback" function pointer, and a void pointer. It calls the DBus
	method, but does not wait for a reply. Instead it sets up the
	callback to be called upon reply. If an error occurs, the errback
	is called instead. Either function will recieve the proxy and the
	value in the void pointer as arguments. The normal callback also
	receives arguments for anything returned by the method.
	(Method.asyncNotifyPrototype): Prototype for new asynchronous
	notification function. See below.
	(Method.asyncNotifyFunction): When the asynchronous dispatch function
	sets up a method call, it specifies the function generated by this
	function as the callback, and passes it an NihAsyncNotifyData struct
	containing the user-provided callback and errback. The asynchronous
	notify function then sets up the error to be handled by the errback
	or marshalls the return values to the callback.
	(Generator.exportTypedefs): This function returns a list of tuples
	* nih-dbus/tests/test_com.netsplit.Nih.Test_proxy.c (test_method_dispatch): 
	of (type, name, args) format for typedefs to be placed in the
	generated header file. Args is present for defining function
	arguments for function pointer typedefs.
	(lineup_typedefs): Works like the other lineup_*s. Outputs typedef
	text from (type, name, args) tuples (see above) in a prettified,
	well-spaced format.
	(typedef_lineup_prefix): Used to make names line up well in
	lineup_typedefs. If a string begins with (* it is returned as is.
	If it begins with * it is returned with one leading space. Otherwise
	it gets two leading spaces.
	* nih-dbus/tests/test_com.netsplit.Nih.Test_proxy.c (test_method_dispatch): 
	Test asynchronous method dispatch

2009-01-29  Scott James Remnant  <scott@netsplit.com>

* nih/alloc.c (nih_alloc_real_set_destructor): Does not modify the
	actual data, so the pointer can be const.
	(nih_ref): Does not modify the actual data, so the pointer can be
	const.
	(nih_unref_only): Does not modify the actual data, and unlike
	nih_unref(), does not free it; so the pointer can be const
	* nih/alloc.h: Update prototypes.

* configure.ac: Bump version to 0.2.1
	* NEWS: Begin 0.2.1

* NEWS: Update

* nih/test_alloc.h (TEST_ALLOC_FAIL): Initialise the count in the
	loop pre-condition, still doesn't solve gcc's issues but I prefer
	it.

* nih/tests/test_command.c (test_help): Array was too small, increase
	the size.

* nih/tests/test_string.c (test_str_split): Oops, left some debugging
	in here.

* nih/file.c (nih_file_read): Never trust a changelog entry that
	says "minor clean-up"; make sure we raise the error before returning
	NULL.

* nih-dbus/dbus_connection.c (nih_dbus_setup)
	(nih_dbus_add_watch, nih_dbus_add_timeout): We should discard
	objects attached to the D-Bus connection since they're floating;
	nobody should take a reference, but good practice and all that.

* nih/alloc.h: Document the different usage patterns

* nih/io.c (nih_io_buffer_resize): Use nih_unref() instead of
	nih_free(), while nothing should have taken a reference, it's a
	good pattern to stick to.
	(nih_io_message_recv): Use nih_local for ctrl_buf
	(nih_io_message_send): Use nih_local for ctrl_buf
	(nih_io_send_message): Take a reference to messages on the send q
	(nih_io_watcher_write): Unreference the message from the NihIo
	object instead of freeing, in case a reference is used elsewhere
	(nih_io_read): Unreference instead of freeing
	(nih_io_get): Unreference instead of freeing
	(nih_io_message_new): Parent should not be the NihIo
	(nih_io_write): Obey that rule here

* nih/tests/test_io.c (test_send_message): Make sure that a
	reference is taken after all.
	(test_watcher): Don't create object with parent as io

* nih/file.c (nih_file_read): Minor clean-up

* nih/main.c (nih_main_set_pidfile): Discard the pid file in case
	someone took a reference to it.

* nih/main.c (nih_main_init_full): Discard the package string in
	case another part of the code has taken a reference to it; since
	it never changes unless this function is called, generate it here
	(nih_main_package_string): dropping this function
	(nih_main_version): Fetch package_string
	* nih/main.h: Add external package_string and drop function proto.
	* nih/tests/test_main.c (test_package_string): Fold these tests into
	(test_init): here.
	* nih/libnih.supp: Update suppression

* nih/logging.c (nih_log_message): Use nih_local for message

* nih/io.c (nih_io_printf): Use nih_local for str

* nih/config.c (nih_config_parse_stanza): Use nih_local for name.

2009-01-28  Scott James Remnant  <scott@netsplit.com>

* nih/file.c (nih_dir_walk_visit): Can't allocate nih_local var
	with a parent, otherwise it'll never be cleaned up.

* nih/config.c (nih_config_parse): Initialise nih_local var to NULL.

* nih/alloc.c (nih_alloc_context_free): After the destructor has
	been called, an object is dead.  Attempting to reference it should
	fail, so we need to store a flag that this has happened.
	(nih_realloc, nih_free, nih_discard, nih_alloc_real_set_destructor)
	(nih_alloc_ref_new, nih_unref, nih_alloc_parent)
	(nih_alloc_ref_lookup, nih_alloc_size): Forbid operations on
	finalised objects.

* nih/tests/test_alloc.c (test_free): Once again I've tripped over
	bugs where the ordering of allocations between siblings in a child
	matters if they refer to each other in their destructor (typical
	case, a hash table in a struct).
	* nih/alloc.c (nih_realloc, nih_alloc_ref_new): Reverse the free
	order, so that the last member allocated is the first one freed.
	This was the original fix for the above bug, but this just moves
	the problem without really fixing it.  I do think it's generally
	correct that the order should be backwards though.
	(nih_free): Since this is the only function that needs to do it,
	take care of casting off parents here.
	(nih_unref): Again, since this is the only function that needs
	to free the context when there are no parents, do it here after
	freeing the reference.
	(nih_alloc_ref_free): Which means this function no longer needs
	to recurse; nih_free() and nih_discard() always directly free a
	context, and nih_unref() knows to if there are no parents left;
	nih_unref() explicitly doesn't free the context.
	(nih_unref_only): No need to pass FALSE to nih_alloc_ref_free() now.
	(nih_alloc_context_free): This gets the big rewrite; rather than
	just recursively freeing the heirarchy, finalise them first by
	calling destructors and then reparenting them to the context
	being freed.  Only free the objects after all destructors are called.

* nih/macros.h (MIN, MAX): Replace with newer evaluation-safe
	nih_min() and nih_max()
	* nih/io.c (nih_io_select_fds): Replace MAX with nih_max
	(nih_io_buffer_pop): Replace MIN with nih_min
	(nih_io_buffer_shrink): Replace MIN with nih_min
	* nih/command.c (nih_command_group_help): Replace MAX with nih_max,
	nicely avoiding multiple function call there.
	* nih/option.c (nih_option_group_help): Likewise.
	* nih/tests/test_io.c (test_select_fds): Replace MAX with nih_max

* nih-dbus/nih_dbus_tool.py (Method.replyFunction): Don't free the
	message passed in to the function.  Since we now require the handler
	function to take a reference to the message during async processing,
	we can't just go around freeing it.
	(Method.replyPrototype): Warn if the error from the reply function
	is ignored, since this is important.
	* nih-dbus/dbus_message.c (nih_dbus_message_error): Likewise we
	should not free the message when passed in for a caller either.
	* nih-dbus/tests/test_dbus_message.c (my_return_error_cb): Update
	to make sure the message is not freed.
	* nih-dbus/tests/com.netsplit.Nih.Test_impl.c (async_method_reply):
	Make sure message is not freed.
	* NEWS: Document the change

* nih/option.c (nih_option_parser): Update documentation to match
	new nih_alloc(), should not use parent for any old allocation.
	(nih_option_join): Update documentation to match new nih_alloc()
	(nih_option_help): Use nih_local for temporary strings and groups
	(nih_option_group_help): Use nih_local for temporary string.
	* nih/option.h: Add documentation string for header.

* nih/list.h, nih/hash.h: Provide a much better documentation string.

* nih/tree.c (nih_tree_new, nih_tree_entry_new): Update documentation
	to match new nih_alloc(); no need to cast destructor function
	* nih/tree.h: Add documentation string for the header.

* nih/hash.c (nih_hash_new): Update documentation to match
	new nih_alloc(); update comment to reflect what we actually do to
	pick a prime.
	(nih_hash_pointer_key, nih_hash_pointer_hash)
	(nih_hash_pointer_cmp): Drop these, we were looking at the raw bytes
	of a pointer, which is almost certainly naughty.
	* nih/hash.h: Add documentation string, remove prototypes.
	(NIH_HASH_FOREACH, NIH_HASH_FOREACH_SAFE): Update documentation in
	same manner as the list functions.
	(nih_hash_pointer_new): Drop, this is probably illegal C ;-)
	(nih_hash_string_new): Update documentation to match new nih_alloc()
	* nih/tests/test_hash.c (test_pointer_new, test_pointer_key): Drop.
	(test_lookup): Modify to use string hashes instead.
	(test_foreach, test_foreach_safe): Fix function name comment.

* nih/list.c (nih_list_new, nih_list_entry_new): Update documentation
	to match new nih_alloc(); No need to cast the destructor function
	anymore.
	* nih/list.h: Add documentation string for the header.
	(NIH_LIST_FOREACH, NIH_LIST_FOREACH_SAFE): Improve documentation
	about which is best.
	(NIH_LIST_ITER): Add macro to make iterating a list with an offset
	head easier.

* nih/macros.h: Add sorely-missed documentation strings, including
	one for the header itself.
	(NULL): Drop, NULL is defined by the C compiler.

* nih/string.c: Update all documentation to match new nih_alloc()
	(nih_str_array_addp): Take a reference to the passed variable
	instead of reparenting (which isn't possible anymore).
	(nih_str_array_add, nih_str_array_addn): Since these just call
	nih_str_array_addp() which now takes a reference rather than
	reparents, we can change these functions to make new_str as a
	local variable.
	(nih_strv_free): Drop this function, it's not used and it's utterly
	inconsistent with the others as it expressly isn't used with
	nih_alloc().
	(nih_strncat): This function worryingly did not work if NULL was
	passed, catch that and call nih_strndup() instead.
	* nih/string.h: Add a documentation string and drop prototype.
	* nih/tests/test_string.c (test_strv_free): Drop.
	(test_sprintf, test_vsprintf, test_strdup, test_strndup): Replace
	TEST_ALLOC_PARENT calls with NULL as the second argument with
	TEST_ALLOC_ORPHAN instead.
	(test_strcat, test_strncat, test_strcat_sprintf)
	(test_strcat_vsprintf): Strangely these test cases don't appear to
	have worked before, the functions return NULL in case of memory
	allocation failure so we need to check the string against a temporary
	copy stored before, and we need to free that string as well. 
	Also add test cases for NULL being passed in as the source string.

* nih/test_alloc.h: Expose references to nih_alloc()'s pointers to
	malloc, realloc and free so we can replace them for testing purposes.
	(TEST_ALLOC_SIZE): Since this returns the size of the allocated object,
	rather than the request, check that the block is at least as large
	as the argument given - not exactly as large.
	(TEST_ALLOC_PARENT): Call nih_alloc_parent directly with both
	arguments, since it's compatible with our calling - can't output the
	current parent now they're may be multiple though.  When passed NULL
	this now checks if it *has* a parent (almost the exact inverse of the
	previous meaning).
	(TEST_ALLOC_ORPHAN): New test to make sure that an object does not
	have a parent.
	(_test_free_tag): Reimplement to lookup the tag block in a linked
	list, instead of a static array, and only return TRUE or FALSE.
	(_test_destructor): Drop, we can just use nih_list_destroy instead.
	(TEST_FREE_TAG): Reimplement to allocate the tag struct itself as
	the child, and place in a linked list.
	(_test_malloc): Add malloc wrapper.
	(_test_allocator): Rename to _test_realloc
	(TEST_ALLOC_FAIL, TEST_ALLOC_SAFE): Change allocator through the
	exposed variables.

* nih/alloc.h (nih_local): Macro to add a variable attribute that
	calls a nih_discard() as a cleanup function when the variable goes
	out of scope.
	* nih/alloc.c (_nih_discard_local): gcc cleanup function wrapper that
	takes the address of the local variable, it gets the actual pointer
	out and passes it to nih_discard().  Unlike the other functions,
	this actually allows the pointer to be NULL.
	* nih/tests/test_alloc.c (test_local): Test local variables work!

* nih/alloc.c (nih_alloc_has_ref): Rename back to nih_alloc_parent.
	(nih_alloc_parent): Accept NULL, if given returns TRUE if there are
	any parents.
	* nih/alloc.h: Update prototype.
	* nih/tests/test_alloc.c (test_parent): Since it's a bit more
	complex, we should probably explicitly test this ;-)

* nih/test.h, nih/test_output.h, nih/test_values.h, nih/test_process.h,
	nih/test_divert.h, nih/test_files.h, nih/test_alloc.h, nih/test_list.h,
	nih/test_hash.h, nih/test_dbus.h: Split the test macros out into
	separate files to make maintaining them easier.  None of them may
	be included directly, execept nih/test_dbus.h which is now no longer
	included by default.
	* nih/Makefile.am (nihinclude_HEADERS): Install new headers.

* nih/alloc.c: Re-implement as a multi-reference allocator; an object
	may now have as many parents as you wish, each one holding its own
	reference to it.
	(NihAllocCtx): Restructure.
	(NihAllocRef): New object linked by context to hold a reference.
	(nih_alloc_init, nih_alloc_set_allocator, nih_alloc_using): Drop
	support for custom allocators, knowing that we always use malloc
	is useful for the implementation - we still allow the test suite
	to change them, but nothing else.
	(nih_alloc): Reimplement from original nih_alloc_using() function,
	now calls nih_alloc_ref_new() if parent is not NULL.
	(nih_realloc): Reimplement for multi-referenceness; much of the
	this remains the same.
	(nih_free): Reimplement as a wrap around nih_alloc_context_free().
	(nih_discard): New function to discard an object if it has no
	parent references, used if you believe references may have been
	taken by functions you have called.
	(nih_alloc_context_free): Common function to free an object, calling
	its destructor after discarding parent references but before cleaning
	up children.
	(nih_alloc_reparent): Drop, it's no longer possible to simply reparent
	an object.  Instead you should call the new functions:
	(nih_ref, nih_alloc_ref_new, nih_unref, nih_alloc_ref_free): Handle
	NihAllocRef objects, linking them to a context and removing them from
	a context; when the last reference to a child is removed, we
	automatically call nih_alloc_context_free().
	(nih_alloc_parent, nih_alloc_has_ref): Replace the former function
	with the latter, it's no longer possible to query the exact parent
	since there isn't one.
	(nih_alloc_ref_lookup): Internal function to find a reference.
	(nih_alloc_size): Reimplement assuming malloc, which saves us some
	space in the context structure.
	* nih/alloc.h: Update all prototypes and documentation, including
	adding module documentation to the top of the header file.
	(NihAllocator): Drop typedef.
	(nih_alloc_set_destructor): Add casting macro with name of original
	function that calls nih_alloc_real_set_destructor().
	* nih/tests/test_alloc.c (test_new, test_alloc): Fix to check for a
	reference rather than the explicit parent; also include a test for
	allocation failure using a malloc hook.
	(test_realloc): Fix to check for a reference rather than the
	explicit parent, change allocatil failure test to use a realloc hook
	instead of a different allocator.
	(test_free): Add a with parent test.
	(test_discard): New test, as test_free() but with different expected
	result for the parent test.
	(test_set_allocator): Drop test.
	(test_reparent, test_ref, test_unref): Drop the former test and
	replace with checking that referencing and unreferencing works.

2008-10-24  Scott James Remnant  <scott@netsplit.com>

* nih/list.h (NIH_LIST_FOREACH_SAFE): Mark the cursor to be
	automatically cleaned up should we exit the loop; this somewhat
	simplifies the definition and allows returning from within the loop.

* nih/list.h (NIH_LIST_FOREACH_SAFE): Fix a typo that caused only
	once cursor variable to be used, rather than one per iteration.

* nih/main.h, nih/main.c, nih/dbus.c, nih/tests/test_dbus.c: Revert
	previous "delete" patch now that we can iterate linked lists
	without tripping over the bug we found here.

* nih/libnih-dbus.supp: Update suppressions for newer glibc and
	D-Bus without debugging enabled.

* nih/list.h (NIH_LIST_FOREACH_SAFE): Replace with a more ingenious
	version based on work by Casey Dahlin and myself; instead of caching
	the next pointer, place a cursor node in the list instead.  This
	solves the issue where the next pointer may be changed or freed, and,
	in fact solves all issues of list rearrangement.
	* nih/tests/test_list.c (test_foreach_safe): Add test cases.
	* nih/hash.h (NIH_HASH_FOREACH_SAFE): Update comment to match.

2008-08-12  Casey Dahlin  <cdahlin@redhat.com>

* nih/main.h (NihMainLoopFunc): Add delete member.
	* nih/main.c (nih_main_loop): Don't run the callback for any function
	marked for deletion, instead call nih_free on it.
	(nih_main_loop_add_func): Initialise delete to FALSE.
	* nih/dbus.c (nih_dbus_release_callback): Add function to mark a
	loop function as deleted.
	(nih_dbus_setup): and use it as the free function instead of nih_free.
	* nih/tests/test_dbus.c (test_connect, test_bus, test_setup): Check
	that the loop functions are marked for deletion instead of freed.

* nih/nih_dbus_tool.py (Output.sourceFile): Include limits.h

2008-07-02  Scott James Remnant  <scott@netsplit.com>

* nih/Makefile.am (test_com_netsplit_Nih_Test_object_SOURCES)
	(test_com_netsplit_Nih_Test_proxy_SOURCES): Add forgotten header.

2008-07-01  Scott James Remnant  <scott@netsplit.com>

* TODO: Update.

* nih/tests/test_com.netsplit.Nih.Test_proxy.c (test_method_dispatch):
	Add test cases for input and output arguments of various types.

* nih/nih_dbus_tool.py (DBusArray.marshal): Add extra parens in
	array setting call for precedence reasons.

* nih/tests/test_com.netsplit.Nih.Test_proxy.c (test_method_dispatch):
	Add basic tests of calls to synchronous and async methods, and the
	usual error returns.
	* nih/tests/com.netsplit.Nih.Test_impl.c (async_method_reply): 
	Add replies that have the wrong combinations of arguments.

* nih/tests/com.netsplit.Nih.Test_impl.c,
	* nih/tests/test_com.netsplit.Nih.Test_object.c (my_connect_handler)
	(my_setup, my_teardown): Move these functions across too.
	* nih/tests/com.netsplit.Nih.Test_impl.h: Add prototypes.

* nih/dbus.c (nih_dbus_proxy_new): Allow name to be NULL.
	* nih/tests/test_dbus.c (test_proxy_new): Test without a name.

* nih/tests/test_com.netsplit.Nih.Test_object.c,
	* nih/tests/com.netsplit.Nih.Test_impl.c: Separate out the server
	object implementation so that the proxy code could use it.
	* nih/tests/com.netsplit.Nih.Test_impl.h: Header for object definition
	* nih/Makefile.am (test_com_netsplit_Nih_Test_object_SOURCES)
	(test_com_netsplit_Nih_Test_proxy_SOURCES): Include the object
	implementation code.

* nih/tests/test_com.netsplit.Nih.Test_proxy.c: Stub file for proxy
	test cases.
	* nih/Makefile.am (TESTS): Build the proxy test suite.
	(test_com_netsplit_Nih_Test_proxy_SOURCES)
	(test_com_netsplit_Nih_Test_proxy_CFLAGS)
	(test_com_netsplit_Nih_Test_proxy_LDFLAGS)
	(test_com_netsplit_Nih_Test_proxy_LDADD): Details for the proxy
	test suite, which actually includes the object code since it needs
	to implement objects too

* nih/nih_dbus_tool.py (MemberWithArgs.variables): Only include arg
	array in object mode.

* nih/Makefile.am ($(com_netsplit_Nih_Test_object_OUTPUTS)): 
	($(com_netsplit_Nih_Test_proxy_OUTPUTS)): Must be newer than the
	source for the python tool

* nih/nih_dbus_tool.py (Interface.variables, Interface.exports):
	Only include the interface definition in object mode, we will need
	something for proxying signals later, but right now this means
	problems when building an object and its proxy together.

* nih/Makefile.am (com_netsplit_Nih_Test_proxy_OUTPUTS)
	(com_netsplit_Nih_Test_proxy_XML)
	($(com_netsplit_Nih_Test_proxy_OUTPUTS)): Generate sources in proxy
	mode for the test interfaces.
	(BUILT_SOURCES, MAINTAINERCLEANFILES, EXTRA_DIST): Build if necessary
	before anything else, clean in maintainer-clean and include in the
	distribution.

2008-06-30  Scott James Remnant  <scott@netsplit.com>

* m4/libs.m4 (NIH_LIB_DBUS): Always check for Python, but don't error
	or disable D-Bus unless the install option is defined.  Otherwise if
	we don't have it, don't define HAVE_PYTHON.
	* nih/Makefile.am (noinst_SCRIPTS): Only build if we have python.

* nih/Makefile.am: Redress the Makefile such that the generated test
	sources are actually included in the distribution tarball.

* nih/dbus.h (NihDDusProxy): Add definition for proxy structure
	and prototype for function to create one.
	* nih/nih_dbus_tool.py (Method.dispatchFunction): Adjust name of
	destination member in the proxy.
	* nih/dbus.c (nih_dbus_proxy_new): Simple function to create a new
	proxy object.
	* nih/tests/test_dbus.c (test_proxy_new): Add simple test for the
	simple function, which will get more complicated if we add signal
	filter registration later.

* nih/errors.h (NIH_DBUS_INVALID_ARGS): Add error caused when the
	reply arguments on a method call were not what we expected.

* nih/nih_dbus_tool.py: Implement the simplest of the method dispatch
	cases, a blocking method call with the reply data returned as arguments
	to the call.

* nih/nih_dbus_tool.py: Allocate a copy of string arguments when
	passing, this makes them consistent with arrays, and also means that
	we can actually do method dispatching which requires the reply data
	to last longer than the underlying message.

* nih/nih_dbus_tool.py: Add parent argument to marshal functions for
	when we need to allocate something (ie. arrays)

* nih/nih_dbus_tool.py (DBusArray.marshal): Add extra parens around
	possible deferenced length variable, not needed for precedence but
	helps clarity in generated code.
	(DBusArray.dispatch): Increment the length inside the for loop, rather
	than always leaving it at zero, useful for debugging.

* nih/nih_dbus_tool.py: Have a bash at sorting out the whole pointer
	and const problem again.  Make them properties of a group, passed to
	type functions that can add * and const as appropriate, and allows
	DBusArray to be more clever about things.  Works for the existing
	cases, anyway.

* nih/nih_dbus_tool.py (Method.handlerPrototype): Only include
	function pointers when the mode is object.

* nih/nih_dbus_tool.py: Allow mode to be changed to proxy, but don't
	specify anything to be generated for that mode yet.

2008-06-11  Scott James Remnant  <scott@netsplit.com>

* Makefile.am (SUBDIRS): po has to come last to make sure we've
	built any auto-generated code before update-po

* nih/nih_dbus_tool.py (Method.marshalFunction): Allow the message
	for the invalid args/type message to be translated.

* nih/tests/test_child.c (test_poll): We end up creating a core file,
	so unlink it.

* nih/Makefile.am (tests/com.netsplit.Nih.Test_object.c tests/com.netsplit.Nih.Test_object.h):
	Create the tests directory.

2008-06-08  Scott James Remnant  <scott@netsplit.com>

* nih/Makefile.am (tests/com.netsplit.Nih.Test_object.c tests/com.netsplit.Nih.Test_object.h):
	Make the tests directory in the output.

* nih/Makefile.am (EXTRA_DIST): Forgot to distribute the test XML

* nih/file.c (nih_file_read): Implement a simpler function for reading
	a file into memory that does literally just that, better than map
	for various reasons.
	* nih/file.h: Add prototype.
	* nih/tests/test_file.c (test_read): Test it works.

2008-06-06  Scott James Remnant  <scott@netsplit.com>

* nih/test.h (TEST_DBUS, TEST_DBUS_OPEN, TEST_DBUS_MESSAGE)
	(TEST_DBUS_CLOSE, TEST_DBUS_END): Various useful macros to set up,
	connect to, pop messages from, close and kill D-Bus connections to
	a private bus daemon.

* nih/tests/test_string.c (test_array_copy): Add a test case for a
	zero-length array, which we need to be able to support.
	* nih/string.c (nih_str_array_copy): Fix it by always creating a
	new array to copy into, since array can't be NULL.

2008-06-04  Scott James Remnant  <scott@netsplit.com>

* nih/tests/test_com.netsplit.Nih.Test_object.c (test_method_marshal):
	Why would I be allocating a string array using sizeof (int32_t),
	fix C&P error to make amd64 happy again.

2008-06-02  Scott James Remnant  <scott@netsplit.com>

* nih/test.h (TEST_DBUS): Initialise _test_address to zeros so
	valgrind shuts up.

* nih/test.h (TEST_DBUS, TEST_DBUS_END): Macros to set up a
	temporary D-Bus session bus for testing purposes.

* nih/tests/test_dbus.c (test_object_new, test_object_destroy)
	(test_object_unregister): Use the system bus for testing, since
	there may be no session bus.

* nih/tests/test_dbus.c (test_bus): We get an error when the
	session bus is not available, so we should eat that before skipping.

2008-06-01  Scott James Remnant  <scott@netsplit.com>

* nih/dbus.c (nih_dbus_object_message): Keep a reference on the
	connection, as well as the message; otherwise if the connection is
	disconnected while handling a async method, we'll end up trying to
	send it to a freed connection instead of just a disconnected and
	forgotten one.
	(nih_dbus_message_destroy): Unreference the connection when freeing
	the message object.

2008-05-28  Scott James Remnant  <scott@netsplit.com>

* TODO (main, timers): Update.

* nih/nih_dbus_tool.py: The C type of string-like types should be
	just "char *"; instead we should add "const" when needed, such as
	in the prototype of handlers and in reply functions.  This avoids
	some const-bending games.
	* nih/tests/test_com.netsplit.Nih.Test_object.c (my_emit_signal):
	Adjust type of string array to match.

2008-05-24  Scott James Remnant  <scott@netsplit.com>

* HACKING: Changed branch location again.

2008-05-18  Scott James Remnant  <scott@netsplit.com>

* nih/error.h (nih_return_no_memory_error): Add a convenience macro
	for raising the ENOMEM system error with the right string, rather
	than setting errno just do it directly.
	* nih/tests/test_error.c (test_return_no_memory_error): Make sure
	the macro is tested.
	* nih/dbus.c (nih_dbus_connect, nih_dbus_bus, nih_dbus_server):
	Use new macro to return ENOMEM when we're not sure that it's the
	current errno.

2008-05-14  Scott James Remnant  <scott@netsplit.com>

* TODO: Update.

* nih/tests/test_com.netsplit.Nih.Test_object.c (my_str_to_int32_array):
	Forgot to clean up parts after splitting.
	(test_method_marshal): Forgot to free self-allocated arrays, and
	we have to free a string array returned by D-Bus as well.
	(test_signal_dispatch): Another string array to be freed.

* nih/tests/test_dbus.c (test_object_message): Don't use timeouts
	to guess when the reply should have arrived, just use a pending
	call notify function.  This speeds the whole thing up a hundred
	fold and removes valgrind slowness issues.

* nih/dbus.c (nih_dbus_message_error): Asynchronous messages need
	a way to return an error message to the sender after the handler
	function has terminated; this function fulfills that need
	* nih/dbus.h: Add prototype.
	* nih/tests/test_dbus.c (test_message_error): Add test case for
	replying to an asynchronous message with an error; this ends up
	somewhat evil since we're not using the bindings.

* nih/nih_dbus_tool.py: Use a namespaced attribute to specify
	whether methods should be generated synchronous (reply generated
	after handler returns) or asynchronous (handler expected to keep
	the message object and call a reply function later).
	* nih/tests/com.netsplit.Nih.Test.xml: Add a test asynchronous
	method, the same basic method as the ordinary test method, but
	which is specified to generate an asynchronous call.
	* nih/tests/test_com.netsplit.Nih.Test_object.c: Add many tests
	for async calls, in fact, we pretty much just duplicate the sync
	tests but use a timer in the server to deliver the reply.

* nih/dbus.c (nih_dbus_object_message): Set a destructor for the
	message that unreferences the attached D-Bus message when it
	is freed, and don't unreference it ourselves.  Also allow the
	handler to return "not yet handled" to mean that the method
	has actually been handled, but the reply hasn't been sent yet.
	(nih_dbus_message_destroy): Destructor for the message.

2008-05-11  Scott James Remnant  <scott@netsplit.com>

* nih/nih_dbus_tool.py: Implement handling for arrays of simple C
	types with an extra length variable, and handling for arrays of
	pointer types with an extra NULL element
	* nih/tests/com.netsplit.Nih.Test.xml: Add test methods with an
	int32 and string array as input and output, and test signals
	with both array types.
	* nih/tests/test_com.netsplit.Nih.Test_object.c: Add tests for
	the new methods and signals, testing the underlying automatic
	generation.

2008-05-10  Scott James Remnant  <scott@netsplit.com>

* nih/string.c (nih_strncat, nih_strcat_vsprintf): Ok, there
	was a minor technical reason after all; don't strlen the
	string if we don't have it.

* nih/string.c (nih_strcat, nih_strncat, nih_strcat_sprintf)
	(nih_strcat_vsprintf): Remove the restriction that the string
	must be pre-allocated, there's no technical reason for it, I was
	just trying to enforce a style.

2008-05-09  Scott James Remnant  <scott@netsplit.com>

* nih/nih_dbus_tool.py: Drop the data type argument, and just
	pass around void *; we never have the types available, and since
	we have our own prototype anyway, we never upset gcc.

* nih/dbus.c (nih_dbus_path): Empty path components are named
	as "_" instead.
	* nih/tests/test_dbus.c (test_path): Test the new functionality.

2008-05-08  Casey Dahlin  <cdahlin@redhat.com>

* nih/file.c (nih_file_is_packaging): Add matches for various
	RPM temporary and atomicity files.

2008-05-08  Scott James Remnant  <scott@netsplit.com>

* nih/dbus.c (nih_dbus_error_raise_printf): Add formatted error
	function, I held out as long as I could
	* nih/dbus.h: Add prototype.
	* nih/tests/test_dbus.c (test_error_raise_printf): And test for it.
	* nih/error.h: Add missing attribute

* nih/Makefile.am: No need for version info if not installing

2008-05-06  Scott James Remnant  <scott@netsplit.com>

* m4/compiler.m4: -Wformat is already in -Wall

* nih/main.c (nih_main_daemonise): Deliberately ignore chdir
	return value, repeat the dup calls until they work.
	(nih_main_loop_interrupt): repeat write call until it succeeds.
	* nih/test.h (TEST_CHILD, TEST_CHILD_WAIT, TEST_CHILD_RELEASE):
	assert that pipe() returns zero and read() and write() both return 1.
	(TEST_DIVERT_STDOUT_FD, TEST_DIVERT_STDERR_FD): assert that dup2
	returns a file descriptor.
	(TEST_FILE_RESET): assert ftruncate works.
	* nih/tests/test_io.c (test_add_watch, test_select_fds)
	(test_handle_fds, test_reopen, test_shutdown, test_destroy)
	(test_watcher, test_read_message, test_send_message, test_read)
	(test_write, test_get, test_printf, test_set_nonblock)
	(test_set_cloexec): assert that the pipe() calls work.
	(test_watcher): assert that write() returns expected number.
	* nih/tests/test_file.c (test_map): Check the fgets works.
	(test_dir_walk): assert that the symlink call works.
	* nih/tests/test_main.c (test_daemonise): assert pipe(), write()
	and getcwd() calls work.
	* nih/tests/test_com.netsplit.Nih.Test_object.c (my_setup):
	initialise wait_fd to get around gcc's blindness.
	(my_emit_signal): initialise ret.

* m4/compiler.m4: Add -Wformat, -Wformat-security and
	-D_FORTIFY_SOURCE=2 to our default CFLAGS unless compiler warnings
	are disabled.

2008-04-29  Scott James Remnant  <scott@netsplit.com>

* nih/tests/test_com.netsplit.Nih.Test_object.c (test_method_marshal)
	(test_signal_dispatch):	For some reason valgrind needs some
	reassurance that it's ok to pass uninitialised data around in various
	cases; probably good for testing anyway.

* nih/dbus.c (nih_dbus_path): Function to generate D-Bus paths with
	appropriate escaping of non-root elements.
	* nih/dbus.h: Add prototype.
	* nih/tests/test_dbus.c (test_path): Test the new function.

* nih/dbus.c (nih_dbus_object_introspect): Free the introspection
	string after sending the message (oops!)

2008-04-27  Scott James Remnant  <scott@netsplit.com>

* nih/tests/com.netsplit.Nih.Test.xml: Add signals to the test
	interface for the variety of basic argument types, we also need
	a glue function to make the server emit the signal.
	* nih/tests/test_com.netsplit.Nih.Test_object.c (my_emit_signal)
	(test_signal_dispatch): Test the signals are emitted and dispatched
	properly by catching them and checking them.

2008-04-26  Scott James Remnant  <scott@netsplit.com>

* nih/test.h (TEST_GROUP): Add macro for when we don't test functions.
	* nih/tests/test_com.netsplit.Nih.Test_object.c (test_method_marshal):
	Use TEST_GROUP here.

* nih/tests/com.netsplit.Nih.Test.xml: Add more methods to test,
	one generic method and two methods (in and out) for each basic type.
	* nih/tests/test_com.netsplit.Nih.Test_object.c: Slightly redo the
	way we do the tests, do the basic set of tests using a single method
	that can return cases such as errors, etc.  Then have input and output
	marshal tests for each of the basic types.
	* nih/nih_dbus_tool.py (NAME_RE): Cope with numerics in member names,
	treat them the same as lowerspace characters.

2008-04-25  Scott James Remnant  <scott@netsplit.com>

* TODO: Update, adding missing pieces for D-Bus support and an
	idea for changing the way that timers/signals/io/etc. work.

* nih_dbus_tool.py: Handle the basic D-Bus types and generate
	marshalling functions for methods and dispatch functions for
	signals, along with all of the glue needed for nih_dbus_object_new()
	* nih/tests/com.netsplit.Nih.Test.xml: Interface to be used for
	testing of the generated code.
	* nih/tests/test_com.netsplit.Nih.Test_object.c: Test suite for
	the generated code (in object mode), so far this just tests a
	couple of methods but will be adding a lot more tests soon.
	* nih/Makefile.am (TESTS): Add the above test suite.
	(test_com_netsplit_Nih_Test_object_SOURCES)
	(test_com_netsplit_Nih_Test_object_CFLAGS)
	(test_com_netsplit_Nih_Test_object_LDFLAGS)
	(test_com_netsplit_Nih_Test_object_LDADD): Details for the test suite.
	(BUILT_SOURCES): Interface definitions are auto-generated and need
	to be done so at the start of the build so deps work properly.
	(CLEANFILES): All built sources need to be cleaned on "make clean"
	(tests/com.netsplit.Nih.Test_object.c tests/com.netsplit.Nih.Test_object.h):
	Generate the interface definitions with the binding tool, being
	sure to regenerate if the XML or binding tool change.

* nih/dbus.c (nih_dbus_object_new): Register an object with D-Bus
	and hook it up to an internal message handling function that deals
	with introspection and the like, while passing off actual handling
	to marshaller functions for individual methods.
	(nih_dbus_object_destroy): When the object is freed, unregister
	it from the bus making sure that doing so doesn't try to free it
	a second time.
	(nih_dbus_object_unregister): When the bus connection is dropped
	or object otherwise unregistered, free it, making sure that doing
	so doesn't try to unregister it a second time.
	(nih_dbus_object_message): Handle messages for the object, locate
	the marshaller function in the interface structures or pass off
	to internal handler for introspection.
	(nih_dbus_object_introspect): Handle the Introspect method by
	generating XML which we return in a reply.
	* nih/dbus.h: Add prototype for new function.
	(NihDBusObject, NihDBusMessage, NihDBusMarshaller, NihDBusArgDir)
	(NihDBusArg, NihDBusMethod, NihDBusSignal, NihDBusAccess)
	(NihDBusProperty, NihDBusInterface): Add the truly insane number
	of structures and enums we need to fully specify the interfaces
	that a D-Bus object provides; you'll never do this by hand! :-)
	* nih/tests/test_dbus.c (test_object_new, test_object_destroy)
	(test_object_unregister, test_object_message): Test cases for new
	functions.
	(test_connect, test_bus): Check error messages using the macros
	rather than by name.

2008-04-23  Scott James Remnant  <scott@netsplit.com>

* nih/tests/test_nih_dbus_tool.py: In hindsight, it's unnecessary
	to test the binding tool directly since the tests will basically
	just compare the output to an expected C file which will make
	maintaining it damned hard and doesn't actually guarantee it works;
	instead we'll test generated output.
	* nih/Makefile.am (TESTS): Remove the call to the Python test suite,
	and reverse the TESTS/check_PROGRAMS thing again to match.

2008-04-22  Scott James Remnant  <scott@netsplit.com>

* nih/libnih-dbus.supp: D-Bus init_system_db() related leaks
	were likely a missing dbus_shutdown() since they've gone away
	now.

* nih/dbus.c (nih_dbus_add_timeout, nih_dbus_timeout_toggled):
	Slightly adjust the millisecond to second conversion to always
	round up to the nearest whole second rather than down; that way
	we have a 1s minimum timeout instead of an immediate one.

2008-04-21  Scott James Remnant  <scott@netsplit.com>

* nih/tests/test_dbus.c (test_bus): Cope when the session bus
	is not available.

* nih/libnih-dbus.supp: Suppress annoying NSS problems on i686
	as well (we did x86-64 last time).  Also found that a couple of
	the suppressions were caused by failing to shutdown properly,
	so remove those (and uncover a D-Bus bug or two in the process).

* nih/tests/test_dbus.c: Remove unnecessary SIGPIPE setting.

* nih/libnih-dbus.supp: I keep finding ways in which D-Bus holds
	on to data, not to mention annoying NSS problems.

* nih/libnih.supp: Add long-missing suppression for the main loop
	functions list, seems we've never actually tested that without
	freeing it manually.

2008-04-18  Scott James Remnant  <scott@netsplit.com>

* nih/dbus.c (nih_dbus_connect, nih_dbus_bus): Functions to connect
	to an abitrary address or a well-known bus, calling our own handler
	on disconnect instead of exit() and setting things up in the main
	loop properly.
	(nih_dbus_setup): Function called by the above, and callable
	externally, to set up the disconnect handler and main loop hook-ups;
	deals with shared connections by checking the main loop slot.
	(nih_dbus_server): Similar function to create a listening server
	and hook it up to the main loop.
	(nih_dbus_add_watch, nih_dbus_remove_watch)
	(nih_dbus_watch_toggled, nih_dbus_watcher): Glue functions so that
	D-Bus can watch file descriptors using our main loop.
	(nih_dbus_add_timeout, nih_dbus_remove_timeout)
	(nih_dbus_timeout_toggled, nih_dbus_timer): Glue functions so that
	D-Bus can set timeouts using our main loop.
	(nih_dbus_wakeup_main): Glue function so that D-Bus can interrupt
	the main loop (I think this is really for multi-threaded apps, but
	it does no harm to force an iteration).
	(nih_dbus_callback): Glue function to dispatch D-Bus messages
	within the main loop.
	(nih_dbus_connection_disconnected): Filter function to catch the
	org.freedesktop.DBus.Local.Disconnected signal and call any
	disconnect handler before unreferencing the connection.
	(nih_dbus_new_connection): Handle new server connections by calling
	the connect handler if set, referencing the new connection then
	setting it up in the main loop.
	* nih/dbus.h (NihDBusDisconnectHandler, NihDBusConnectHandler):
	Function prototype typedefs for disconnect and connect handlers.
	* nih/tests/test_dbus.c (test_connect, test_bus, test_setup)
	(test_server): Test the new functions as best we can.
	* nih/libnih-dbus.supp: D-Bus slot allocator doesn't free memory.

* nih/main.c (nih_main_loop_init): Make a non-static function.
	* nih/main.h: Add prototype.

2008-04-16  Scott James Remnant  <scott@netsplit.com>

* nih/test.h (TEST_FILE_NE, TEST_FILE_NE_N): Fix logic of tests.

2008-04-12  Scott James Remnant  <scott@netsplit.com>

* nih/Makefile.am: If we're not installing the library then we
	want to still make the script but don't want to install it.

* nih/nih_dbus_tool.py: Skeleton code for the Python binding tool.
	* nih/tests/test_nih_dbus_tool.py: Test cases for the dbus tool.
	* nih/Makefile.am (TESTS): When building the dbus library, also run
	the Python test suite for the Python binding tool; this requires
	reversing the check_PROGRAMS/TESTS setting since it needs to only
	be in TESTS.

* nih/libnih-dbus.supp, nih/libnih-dbus.ver: Library support files.

* nih/dbus.c (nih_dbus_error_raise): Begin the D-Bus library with
	a function to raise an NihError that can be converted into a
	DBusError when necessary (to be used in function returns).
	* nih/dbus.h (NihDBusError): Type for the structure since we need
	to include a name member.
	* nih/tests/test_dbus.c (test_error_raise): Test case.
	* nih/errors.h: Add NIH_DBUS_ERROR error; no string for this since
	each individual error will have its own.

2008-04-11  Scott James Remnant  <scott@netsplit.com>

* m4/misc.m4: Reverse the sense of the noinstall option, so that
	"install" needs to be present for libnih to be installed.
	* configure.ac: Install libnih when built from its own source.

2008-03-29  Scott James Remnant  <scott@netsplit.com>

* nih/Makefile.am (libraries): Build optional libnih-dbus.la
	(libnih_dbus_la_SOURCES, libnih_dbus_la_CFLAGS)
	(libnih_dbus_la_LIBS, -version-info 0, libnih_dbus_la_LDFLAGS):
	Details for optional library.
	(EXTRA_DIST): Distribute the version script and suppressions files.
	(nihinclude_HEADERS): Install the optional libdbus header
	(bin_SCRIPTS): Build optional nih-dbus-tool binding tool script
	(CLEANFILES, EXTRA_DIST, do_subst, nih-dbus-tool): Create installed
	script by substituting in another, be sure to distribute the other
	and clean the intermediate file.
	(TESTS): Optional test suite
	(test_dbus_SOURCES, test_dbus_CFLAGS, test_dbus_LDFLAGS)
	(test_dbus_LDADD): Details for the optional dbus test suite.
	* m4/misc.m4 (AC_COPYRIGHT): Also add a Makefile PACKAGE_COPYRIGHT
	variable for substitution.
	(NIH_INIT): We have separate cflags for dbus-related tools, so we
	need to check that gcc supports -c and -o.

* m4/libs.m4 (NIH_LIB_DBUS): Macro to detet whether pkg-config,
	D-Bus and Python are available and decide based on that whether or
	not we can build an optional D-Bus binding library; configure options
	and arguments determine whether being unable to is a warning or an
	error.
	* m4/misc.m4: Add the dbus option to the help and the call to check
	for the libraries.
	* README: Add a section on the dependencies this introduces.

* m4/libs.m4: Add an empty file to hold macros relating to library
	detection.
	* m4/Makefile.am (dist_aclocal_DATA): Install and distribute the
	new macro file.
	* nihify: Symlink the new macro file across as well.

2008-03-19  Scott James Remnant  <scott@netsplit.com>

* nih/hash.c (nih_hash_pointer_hash): Fix hash generation on 64-bit
	systems by using each byte rather than trying to be clever.

2008-03-14  Scott James Remnant  <scott@netsplit.com>

* nih/hash.c (nih_hash_new): Also require hash and cmp functions
	and store in the structure.
	(nih_hash_add, nih_hash_add_unique, nih_hash_add_replace)
	(nih_hash_search, nih_hash_lookup): Change key type to void,
	use hash and cmp functions from the structure.

	and pass in common key, hash and cmp functions.
	* nih/tests/test_hash.c: Update tests to include new functions and
	macros.
	* nih/watch.c: Use nih_hash_string_new() to create the hash table.

* nih/command.c: Add const to local structures.
	(nih_command_join): Expect to not change the structures passed
	(nih_command_handle): Iterate structure as const.
	* nih/command.h: Add const to prototype.
	* nih/option.c: Add const to local structures.
	(nih_option_join): Expect to not change the structures passed
	* nih/option.h: Add const to prototype.

* nih/error.c (nih_error_init): Make extern for consistency.
	* nih/error.h: Add prototype.
	* nih/logging.c (nih_log_init): Make extern for consistency.
	* nih/logging.h: Add prototype.

* nih/child.c (child_watches): Rename to nih_child_watches and
	make extern.
	(nih_child_init): Make extern, update name of global.
	(nih_child_add_watch, nih_child_poll): Update name of global.
	* nih/child.h: Add prototypes.
	* nih/io.c (io_watches): Rename to nih_io_watches and make extern.
	(nih_io_init): Make extern, update name of global.
	(nih_io_add_watch, nih_io_select_fds, nih_io_handle_fds): Update
	name of global.
	* nih/io.h: Add prototypes.

	name of global.
	* nih/timer.h: Add prototypes.

* m4/misc.m4 (NIH_INIT): Allow the macro to take options, the first
	of which shall be "noinstall" which defines a Makefile conditional
	that prevents installation of files -- useful when embedded in
	things like Upstart.
	* m4/Makefile.am (dist_aclocal_DATA): Don't install if "noinstall"
	is defined.
	* nih/Makefile.am (lib_LTLIBRARIES): If "noinstall" is defined,
	still build the library but do not install it.
	(include_HEADERS): Don't install if "noinstall" is defined.

2008-03-08  Scott James Remnant  <scott@netsplit.com>

* HACKING: Don't even need /product/ anymore.

* HACKING: Terminology changes: Bazaar-NG is now just Bazaar;
	Malone is now just Launchpad's bug tracking system.

2008-03-07  Scott James Remnant  <scott@netsplit.com>

* nih/error.h (NIH_SHOULD): We quite often need to loop while
	we get ENOMEM, but break on another error; this does that.
	* nih/watch.c (nih_watch_new): Use here, fixing a bug in the process
	where we didn't re-raise the error again.

2008-03-06  Scott James Remnant  <scott@netsplit.com>

* nih/string.c (nih_strcat, nih_strncat, nih_strcat_sprintf)
	(nih_strcat_vsprintf): I'm needing to use realloc more than I should
	for string concatenation, so lets have some functions to do that.
	* nih/string.h: Prototypes for new functions.
	* nih/tests/test_string.c (test_strcat, test_strncat)
	(test_strcat_sprintf, test_strcat_vsprintf): Test the new functions.

* TODO: Update.

2008-03-03  Scott James Remnant  <scott@netsplit.com>

* nih/tests/test_config.c (test_token): Also check that backslashes
	can escape themselves; since you may want a literal one followed by
	whitespace or a newline.
	* nih/config.c (nih_config_token): Dequote blackslash following a
	blackslash.

* nih/tests/test_config.c (test_token): We don't want to dequote
	anything other than newlines and whitespace, since the quote
	characters may be important for the value (e.g. \$FOO being different
	to $FOO).  Add tests to make sure we don't.
	* nih/config.c (nih_config_token): After a slash, only dequote
	whitespace otherwise if we're copying, copy a literal slash character
	first.

* nih/tests/test_string.c (test_array_append): Should work with a
	NULL array argument.
	* nih/string.c (nih_str_array_append): Make it work.
	(nih_str_array_copy): Which makes this function somewhat simpler.

2008-03-02  Scott James Remnant  <scott@netsplit.com>

* nih/libnih.supp (nih-command-parser, nih-option-parser): Suppress
	leak of internal state during --help tests.
	(nih-main-package-string-test): Modify suppression to also catch
	when it's allocated within a test case.

2008-03-01  Scott James Remnant  <scott@netsplit.com>

* nih/tree.h (NIH_TREE_FOREACH_FULL, NIH_TREE_FOREACH_PRE_FULL)
	(NIH_TREE_FOREACH_POST_FULL): The lack of these macros was silly.
	* nih/tests/test_tree.c (test_foreach_full)
	(test_foreach_pre_full, test_foreach_post_full): Add tests.

* nih/tree.c (nih_tree_next, nih_tree_prev, nih_tree_next_pre)
	(nih_tree_prev_pre, nih_tree_next_post, nih_tree_prev_post): Rename
	these functions to *_full and add filter and data pointers, where
	the filter must return FALSE if given otherwise a node is ignored.
	* nih/tree.h: Update prototypes, and keep previous behaviour with
	the old names through the use of macros.  Typedef the filter function
	pointer type.
	* nih/tests/test_tree.c (test_next_full, test_prev_full)
	(test_next_pre_full, test_prev_pre_full, text_next_post_full)
	(test_prev_post_full): Test iteration with filters.

2008-01-16  Scott James Remnant  <scott@netsplit.com>

* nih/tree.c (nih_tree_next, nih_tree_prev, nih_tree_next_pre)
	(nih_tree_prev_pre, nih_tree_next_post, nih_tree_prev_post): It's
	never possible to break out of the loop since we always return
	inside it.

* nih/tests/test_child.c (test_poll): Add test case for the watch
	being on the wrong event.

* m4/compiler.m4 (NIH_COMPILER_COVERAGE): Allow this to disable
	use of -Os, which otherwise wouldn't be.

* configure.ac (AC_COPYRIGHT): Update copyright to 2008.

2008-01-15  Scott James Remnant  <scott@netsplit.com>

* nih/tests/test_child.c (test_poll): Don't run the ptrace tests
	under valgrind, since they upset it somewhat and return different
	things (I expect we end up tracing valgrind itself).

* nih/main.c (nih_main_daemonise): Formatting fix.

2008-01-14  Scott James Remnant  <scott@netsplit.com>

* HACKING: Correct bzr URL to trunk.

2007-12-06  Scott James Remnant  <scott@netsplit.com>

* nih/child.c (nih_child_poll): I give up.  The wait queue can change
	between an invocation of waitid with WNOWAIT and the invocation later
	to "remove" the entry.  WNOWAIT is a waste of time, and no matter how
	useful it might have been, I just see no way of actually using it.
	* nih/child.h: Update documentation.

2007-12-02  Scott James Remnant  <scott@netsplit.com>

* nih/signal.c (nih_signal_set_handler): Drop the SA_NOCLDSTOP flag
	from when we were setting SIGCHLD, I've no idea why this crept in
	and it now stops us doing things we want to.
	* nih/tests/test_signal.c (test_set_handler): Remove the test for it.

* nih/tests/test_child.c (test_poll): Fix for AMD64, the data
	argument for PTRACE_GETEVENTMSG is unsigned long, which is larger
	than pid_t here.

* nih/tests/test_child.c (test_poll): Fix up several race
	conditions in the ptrace test cases, there are a lot of quirks you
	have to remember when dealing this most insane of syscalls.
	(signal from traced child): Once we've finished the test we must
	detach from the child otherwise we'll trap our own SIGTERM and the
	child won't exit.  Tthere's no need to send SIGCONT since this
	is an ordinary ptrace signal trap.
	(exec by traced child): Detach and send SIGCONT in case the process
	we run gets a signal delivered to it; if that happened, we'd trap
	that signal and the child would never exit.
	(fork by traced child): This is the most pathalogical.  We had a
	race where nih_child_poll() was actually reaping the event for the
	child stopping.  Change to get the child pid and wait for it before
	calling the poll function.  Don't bother waiting for the child to
	terminate, we shouldn't ever find out if we've detached properly.

2007-11-29  Scott James Remnant  <scott@netsplit.com>

* nih/main.c (nih_main_write_pidfile): Have to cast the difference
	in pointers to int, otherwise we get a compiler warning on amd64.

* nih/child.c (nih_child_poll): Remove the hacks that shift the
	status information back now that we have a kernel patch in akpm's
	tree to fix it.

2007-11-15  Scott James Remnant  <scott@netsplit.com>

* nih/child.c (nih_child_poll): I found out what was causing the
	signal information to be missing for CLD_STOPPED, a kernel bug;
	cope with it for now by shifting the status across 8 bits for
	CLD_TRAPPED and CLD_STOPPED until I get Roland to fix that bit.
	* nih/tests/test_child.c (test_poll): Replace sleeps with waitid
	WNOWAIT calls now that that particular kernel bug is fixed; add
	a couple of pauses so that the child doesn't exit and clean up
	the wait queue before we get a chance to look.  Add a wait on the
	child stopping after fork to avoid a race condition where the child
	isn't actually running yet when we try and detach from it.

* nih/child.h (NihChildWatch): Add events member and rename reaper
	to handler, since it can now be called for things like stop, trap
	and ptrace events.
	(NihReaper): Rename to NihChildHandler
	(NihChildEvents): Enumeration/bit flags for events member
	* nih/child.c (WAITOPTS): Define wait options in one place to make
	repeating them easier.
	(nih_child_add_watch): Add events argument and change type and name
	of function argument, set in the structure.
	(nih_child_poll): Rather than just working out a killed boolean (which
	was wrong anyway since it didn't take CLD_DUMPED into account), we
	store one of many events in the event argument and convert status if
	necessary (bit shifting for CLD_TRAPPED and ptrace events).  Check
	this event against the events mask in the watch, and pass to the
	handler.
	* nih/tests/test_child.c (test_add_watch): Check that events and
	handler are initialised correctly.
	(test_poll): Many new test cases for exiting, killing, aborting,
	stopping, continuing, trapping and ptracing.

2007-11-03  Scott James Remnant  <scott@netsplit.com>

* nih/watch.h (NihWatch): Add created hash table so we can easily
	delay the create_handler until the file is closed.
	* nih/watch.c (nih_watch_new): Initialise the created hash table.
	(nih_watch_handle): When a file is created, add an entry to the
	created hash table and return without calling a handler -- for all
	paths, check for and remove any remove any existing created entry;
	call create_handler instead of modify_handler if this exists, and
	don't call delete_handler at all.
	* nih/tests/test_watch.c (test_new): Check created is initialised.
	(test_reader): Test that creating a file doesn't trigger create
	until it's closed and that unlinking a file before it's been closed
	doesn't trigger at all.

* nih/test.h (TEST_FREE_TAG): assert that we don't use this on
	a NULL pointer.

2007-11-02  Scott James Remnant  <scott@netsplit.com>

* nih/test.h (TEST_FUNCTION_FEATURE): Add macro for when we're
	testing a specific feature of a function.

2007-10-27  Scott James Remnant  <scott@netsplit.com>

* m4/compiler.m4 (NIH_COMPILER_OPTIMISATIONS): Add extra [...]

* m4/compiler.m4 (NIH_COMPILER_WARNINGS): Add missing [...] around
	the second argument to AS_IF.
	(NIH_COMPILER_OPTIMISATIONS): Fix wrong use of [..][..] to [....]
	(NIH_COMPILER_COVERAGE): Remove extraneous comma

* m4/linker.m4 (NIH_LINKER_VERSION_SCRIPT): Restore AM_CONDITIONAL
	that was mistakenly dropped.

2007-10-26  Scott James Remnant  <scott@netsplit.com>

* m4/linker.m4 (NIH_LINKER_SYMBOLIC_FUNCTIONS): Test that checks
	for -Bsymbolic-functions

* m4/linker.m4: Style fix.

* m4/compiler.m4 (NIH_COMPILER_COVERAGE, NIH_COMPILER_OPTIMISATIONS)
	(NIH_COMPILER_WARNINGS): Update to use AS_IF.

* m4/compiler.m4 (NIH_C_THREAD): Shell fix.

* m4/linker.m4 (NIH_LINKER_OPTIMISATIONS): Update to use AS_IF.

* m4/linker.m4 (NIH_LINKER_VERSION_SCRIPT): Update so it supports
	a config.cache

2007-10-24  Scott James Remnant  <scott@netsplit.com>

* nih/file.c (nih_file_map): Catch a file larger than the length of
	size_t and raise the standard EFBIG error message.  Noticed by
	Kees Cook.

2007-10-15  Scott James Remnant  <scott@netsplit.com>

* nih/alloc.c (nih_alloc_using, nih_alloc_reparent, nih_realloc):
	Change the order in which children allocations are stored in the
	list such that the last allocation is freed first rather than
	the other way around.  This solves issues of children being stored
	inside an allocated hash table which will be freed first.

* m4/misc.m4 (NIH_INIT): Use AC_PROG_CC_C99 instead of NIH_C_C99
	* configure.ac: Bump Autoconf dependency to 2.61
	* HACKING: Likewise increase documentation

* HACKING: Correct Bazaar branch now we're natively hosted on LP

* nih/test.h (_test_allocator): Mark used in case it isn't.
	(_test_free_tag, _test_free_tags, _test_destructor)
	(TEST_FREE_TAG, TEST_FREE, TEST_NOT_FREE): Since destructors are
	now intended for internal use by an object, we shouldn't abuse them
	in test cases like we were doing - since we might not chain up
	properly and miss vital behaviour as a result.  Instead implement
	some tests that use a destructor on an nih_alloc() child of the object
	to determine freeness.
	* nih/tests/test_watch.c (test_reader): Use TEST_FREE instead of
	a custom destructor, which are no longer favoured for this kind
	of work.
	* nih/tests/test_error.c (test_raise_again, test_pop_context): 
	Use TEST_FREE instead of custom destructor.
	* nih/tests/test_timer.c (test_poll): Use TEST_FREE/TEST_NOT_FREE
	* nih/tests/test_child.c (test_poll): Use TEST_FREE, etc.
	* nih/tests/test_io.c (test_shutdown, test_watcher)
	(test_read_message, test_read, test_get): Use TEST_FREE, etc.

* nih/hash.c, nih/timer.c, nih/signal.c, nih/child.c, nih/io.c,
	nih/watch.c: Document why non-allocated versions of functions
	are missing.
	* TODO: Update.

2007-10-14  Scott James Remnant  <scott@netsplit.com>

* nih/alloc.c (nih_free): Call destructors before freeing children,
	this makes them more consistent with being structure clean-up
	functions rather than using them to detect a free.  Don't return
	values from children destructors.
	* nih/tests/test_alloc.c (test_free): Adjust test, return values
	from children destructors are never returned.

* nih/watch.c (nih_watch_new): Make the io structure an nih_alloc
	child of the watch, now that we don't perform any kind of lazy
	freeing or closing.
	(nih_watch_destroy): No need to close the io structure since it'll
	be automatically freed, just set the flag to be caught in the reader.
	* nih/tests/test_watch.c (test_new): Check parent of watch->io
	is watch, not NUL.
	(test_destroy): Don't use the destructor anymore, nih_alloc is tested
	elsewhere.
	(test_reader): Don't use destructor to test watch->io
	(my_destructor): Always call nih_watch_destroy since this is only
	used for that.

* nih/io.c (nih_io_close): Rename to nih_io_destroy, setting a free
	flag in the structure if necessary before closing the descriptor
	and calling the error handler if there's a problem.
	(nih_io_reopen): Set destructor
	(nih_io_watcher): Rename lazy_close to caught_free and check its
	value after any calls to the reader, error handler or close handler
	functions; if true, simply bail out.  Reorder leaving so that a
	shutdown check happens last (since this can free the structure).
	(nih_io_closed): Now simply calls the close handler if it exists,
	otherwise frees the structure.
	* nih/io.h (NihIo): Rename close member to free.
	Update prototypes.
	* nih/tests/test_io.c (my_reader, test_reopen): Use nih_free
	instead of nih_io_close.
	(test_reopen): Create new fds each time, since they are closed
	on free now.
	(destructor_called): Chain up to call nih_io_destroy
	(test_close): Rename to test_destroy and alter appropriately.
	(test_watcher): Adjust documentation to say we're checking that free
	is called in the reader.
	(test_send_message, test_write, test_printf): Open pipes rather
	than just stdout, because that will end up closed.

2007-10-12  Scott James Remnant  <scott@netsplit.com>

* nih/watch.h (NihCreateHandler, NihModifyHandler, NihDeleteHandler):
	Modify doc strings to mention nih_free instead of nih_watch_free

* nih/tests/test_file.c (my_visitor): Set destructor for the list
	entries we create as we go.

* nih/watch.c (nih_watch_reader): Rework the function slightly,
	instead of using the free pointer to free at the end of the handler,
	use it to detect the free after the handler returns and immediately
	abort -- it means we won't process remaining watches but meh.
	(nih_watch_handle): Get passed the caught_free flag and check it
	after calling any handlers to make sure we abort properly.
	(nih_watch_free): Rename to nih_watch_destroy and just handle the
	internal cleanup.
	(nih_watch_new): Set the destructor properly.
	* nih/watch.h: Update prototypes.
	* nih/tests/test_watch.c (test_free): Rename to test_destroy.
	(my_delete_handler): Use nih_free not nih_watch_free
	(my_destructor): Chain up to nih_watch_destroy for NihWatch.

* nih/tests/test_watch.c (my_destructor): Neither NihWatch nor NihIo
	need a destructor to be called.

* nih/tests/test_child.c (test_poll): Fix erroneous removal of "1"

* TODO: Update.

2007-10-11  Scott James Remnant  <scott@netsplit.com>

* nih/option.c, nih/command.c, nih/config.c: Remove references to
	nih_alloc_set_destructor() from doc strings since this is now
	considered bad practice.

* nih/main.c (nih_main_loop_add_func): Adjust call to set destructor
	* nih/tests/test_main.c (test_main_loop)
	(test_main_loop_add_func): Call nih_free instead of nih_list_free

* nih/watch.c (nih_watch_add, nih_watch_handle): Call nih_free
	instead of nih_list_free
	(nih_watch_add): Set destructor to nih_list_destroy for now.
	* nih/tests/test_watch.c (my_destructor): Call nih_list_destroy
	for NihWatch structure.

* nih/file.c (nih_dir_walk_visit): Call nih_free instead of
	nih_list_free
	(nih_dir_walk, nih_dir_walk_visit): Set destructor on object.

* nih/tests/test_io.c (test_add_watch, test_select_fds)
	(test_handle_fds, test_shutdown, test_watcher): Call nih-free
	instead of nih_list_free
	(destructor_called): Call nih_list_destroy when passed an
	NihIoMessage; a bit icky since this is also called for an NihIo
	which doesn't have a destructor (yet)

* nih/io.c (nih_io_watcher_write, nih_io_read, nih_io_get): Call
	nih_free instead of nih_list_free.
	(nih_io_add_watch): Adjust call to set destructor
	(nih_io_message_new): Set a destructor so the message is removed
	from a list when freed.

* nih/child.c (nih_child_add_watch): Adjust call to set destructor
	(nih_child_poll): Call nih_free instead of nih_list_free
	* nih/tests/test_child.c (test_add_watch, test_poll): Call nih_free
	instead of nih_list_free.
	(my_destructor): Call nih_list_destroy().

* nih/string.c: Fix documentation as below.

* nih/hash.c: Fix doc string, destructors are now considered internal
	and shouldn't be set by callers.

* nih/signal.c (nih_signal_add_handler): Adjust call to set destructor
	* nih/tests/test_signal.c (test_add_handler): Call nih_free instead
	of nih_list_free

* nih/timer.c: Fix doc strings

* nih/timer.c (nih_timer_add_timeout, nih_timer_add_periodic)
	(nih_timer_add_scheduled): Adjust calls to set destructor.
	(nih_timer_poll): Call nih_free rather than nih_list_free.
	* nih/tests/test_timer.c (test_add_timeout, test_add_periodic)
	(test_add_scheduled, test_next_due): Call nih_free rather than
	nih_list_free
	(my_destructor): Call the list destructor.

* nih/tree.c (nih_tree_destructor): Rename to nih_tree_destroy()
	(nih_tree_free): Drop.
	(nih_tree_new, nih_tree_entry_new): Set destructor.
	* nih/tree.h: Update prototypes.
	* nih/tests/test_tree.c (test_destructor): Rename.
	(test_free): Drop

* nih/: Documentation string fix.

* nih/tests/test_hash.c (test_string_key): Replace nih_list_free
	call with nih_free, since we're not overriding the destructor.

* nih/list.c (nih_list_free): Drop this function.
	(nih_list_destructor): Rename to nih_list_destroy()
	(nih_list_new, nih_list_entry_new): Set destructor function.
	* nih/list.h: Update prototypes.
	* nih/tests/test_list.c (test_destructor): Rename.
	(test_free): Drop.
	(test_add): Replace nih_list_free calls with nih_free

2007-10-08  Scott James Remnant  <scott@netsplit.com>

* configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.16.1 since this
	version of gettext is needed for compatibility with Automake 1.10
	* HACKING: Bump version in the docs too.

* Makefile.am (ACLOCAL_AMFLAGS): Specify that aclocal install
	ordinarily system-wide macros into m4 (libtool.m4, specifically).
	This makes it easier for packagers to modify autoconfery since
	aclocal is no longer a destructive event.
	* configure.ac (AM_INIT_AUTOMAKE): Increase Automake requirement to
	1.10 to ensure we have aclocal --instal
	* HACKING: Increase Automake version in the docs.

2007-06-22  Scott James Remnant  <scott@netsplit.com>

* nih/tests/test_tree.c (test_next, test_prev, test_next_pre)
	(test_prev_pre, test_next_post, test_pre_post): Add tests for a
	single-node tree, because we found a bug where it didn't work.
	* nih/tree.c (nih_tree_next): Bug fix; check there is a right node
	before checking whether we've returned from it, otherwise we could
	confuse it with starting at the top of the tree.
	(nih_tree_prev): Likewise check there is a left node before checking
	whether we've returned from it.

2007-06-20  Scott James Remnant  <scott@netsplit.com>

* nih/config.c (nih_config_parse_stanza): Free name after use.

* nih/config.c (nih_config_parse_stanza): Don't dequote stanza
	names, since otherwise they can't be made non-special; if we don't
	recognise the stanza we parsed, raise the error without updating
	pos, since we want it to point to the start of the token.
	* nih/tests/test_config.c (test_parse_stanza): Update pos in test.

2007-06-18  Scott James Remnant  <scott@netsplit.com>

* nih/list.h (NihListEntry): Define structure combining an NihList
	with a union of common types.
	* nih/list.c (nih_list_entry_new): Add a helper function for when
	we need a simple entry without any extra structure around it.
	* nih/tests/test_list.c (test_entry_new): Test the new function.
	* nih/tree.h (NihTreeEntry): Define structure combining an NihTree
	with a union of common types.
	* nih/tree.c (nih_tree_entry_new): Add a helper function for when
	we need a simple node without any extra structure around it.
	* nih/tests/test_tree.c (test_entry_new): Test the new function.

	(test_next_pre, test_foreach_pre, test_prev_pre, test_next_post) 
	(test_foreach_post, test_prev_post): Add tests for partial tree
	traversal, we don't expect to break out of the confines of the
	root that we've set, even if it has a parent.
	* nih/tree.c (nih_tree_next, nih_tree_prev, nih_tree_next_pre)
	(nih_tree_prev_pre, nih_tree_next_post, nih_tree_prev_post): Before
	moving up to the parent node, check whether the current node is the
	tree root; if it is, return NULL instead since we've iterated the
	sub-tree we were looking at.

* nih/tests/test_tree.c (test_next, test_foreach, test_prev) 
	(test_next_pre, test_foreach_pre, test_prev_pre, test_next_post) 
	(test_foreach_post, test_prev_post): Use two different arrays to
	make it really obvious how the tree is constructed and what order
	we really expect it to be in.  This makes it easier to get ready for
	the next bit ...

* nih/tree.c (nih_tree_next, nih_tree_prev): Minor bug fix, set the
	previous to the tree's parent when visiting for the first time so that
	partial	tree iterations might be able to work.  Make algorithm code
	simpler and more readable.
	(nih_tree_next_pre, nih_tree_prev_pre): Algorithm for non-recursive
	pre-order tree iteration, note that unlike the above, these are not
	symmetrical.
	(nih_tree_next_post, nih_tree_prev_post): Algorithm for non-recursive
	post-order tree iteration, note that these aren't symmetrical with
	each other, but are the symmetrical equivalents of the pre-order
	functions.
	* nih/tree.h: Add prototypes for new functions.
	(NIH_TREE_FOREACH_PRE, NIH_TREE_FOREACH_POST): Add convenience
	iteration macros for pre-order and post-order iteration.
	* nih/tests/test_tree.c (test_next, test_foreach, test_prev): Add
	some documentation for the tree shape, and how we work out the node
	numbers.  In each case, we were accidentally giving the expected
	first node (which fortunately always worked); to test this harder,
	give the root node instead!
	(test_next_pre, test_foreach_pre, text_prev_pre): Test pre-order
	tree iteration with the same basic code.
	(test_next_post, test_foreach_post, text_prev_post): Test post-order
	tree iteration with the same basic code.

2007-06-12  Scott James Remnant  <scott@netsplit.com>

* nih/test.h (TEST_HASH_NOT_EMPTY): Add missing ;

* nih/main.c (nih_main_unlink_pidfile): Add for completeness.
	* nih/main.h: Add prototype.
	* nih/tests/test_main.c: Use the new function here for testing.

* nih/main.c (nih_main_pidfile): Rename to nih_main_write_pidfile
	(nih_main_set_pidfile, nih_main_get_pidfile) 
	(nih_main_read_pidfile): Add companion functions to set and get the
	current location, and also read from it.
	* nih/main.h: Add prototypes.
	* nih/tests/test_main.c (test_set_pidfile, test_read_pidfile) 
	(test_write_pidfile): Test the functions as best we can.

* nih/main.c (nih_main_daemonise): Cut the pid file writing out
	(nih_main_pidfile): and place it into its own function, since we
	seem to use this elsewhere too.
	* nih/main.h: add prototype.

* nih/main.c (nih_main_daemonise): Don't just write the pid file
	directly, and hope it works.  Write to a temporary file, flush and
	sync it, then rename to the real filename.  This provides a "if the
	pid file exists, a pid can be read from it" contract - or at least,
	the nearest we can to that.

2007-06-11  Scott James Remnant  <scott@netsplit.com>

* nih/config.c (nih_config_skip_block): Simple function to skip over
	a block inline without parsing it into a string.
	* nih/config.h: Add prototype.
	* nih/tests/test_config.c (test_skip_block): Test the new function.

2007-06-10  Scott James Remnant  <scott@netsplit.com>

* nih/test.h (TEST_HASH_EMPTY, TEST_HASH_NOT_EMPTY): Add some
	tests for hash emptyness.

2007-06-03  Scott James Remnant  <scott@netsplit.com>

* nih/file.h (NihFileFilter): add missing data pointer to definition.
	* nih/file.c (nih_dir_walk_scan): Take the data pointer and pass it
	to the filter function.
	(nih_dir_walk, nih_dir_walk_visit): Pass data pointer to scan function.
	(nih_file_ignore): Accept and ignore a data pointer.
	* nih/tests/test_file.c (my_filter): Add data pointer.
	(test_ignore): Pass NULL for data pointer.
	* nih/watch.c (nih_watch_handle): Pass data to filter function.
	* nih/tests/test_watch.c (my_filter): Add data pointer.

2007-05-27  Scott James Remnant  <scott@netsplit.com>

* nih/config.c (nih_config_parse): Since we've elimated all of the
	uses of ssize_t in this code, we're safe to parse a file larger
	than SSIZE_MAX, so drop the check.
	* nih/errors.h (NIH_CONFIG_TOO_LONG): Drop this error, since there
	can be no such case anymore; technically we don't handle very large
	files since we can only map 4GB of memory, but we fail by mapping
	a smaller part of the file, rather than overrunning any buffers.

* nih/config.c (nih_config_parse_block): Don't use -1 in ws to
	indicate we've not counted it yet, instead use the current value
	of lines; this elimates the last ssize_t from the code.

* nih/config.c (nih_config_block_end): Modify to return TRUE or
	FALSE, and set the end position through an argument instead.
	(nih_config_parse_block): Update the way we call nih_config_block_end
	to receive the end location via the pointer, rather than as the
	return value.

* nih/config.c (nih_config_token): Change return value to an int,
	and return the token length through an argument pointer if given.
	This eliminates a need for ssize_t for this function.
	(nih_config_next_token, nih_config_parse_command): Update way we
	call nih_config_token to obtain the length through a pointer, and
	directly check the return value to decide whether to abandon it.
	* nih/config.h: Update prototype.
	* nih/tests/test_config.c (test_token): Update the tests to check
	the pointed value for the length, and the return value for error.

2007-05-18  Scott James Remnant  <scott@netsplit.com>

* nih/tests/test_string.c (test_array_append): Make sure that the
	array is returned unaltered (at least, apparently) if any allocation
	fails during the append.
	* nih/string.c (nih_str_array_append): Record the original length,
	and pass always pass our local length variable to nih_str_array_add.
	Before returning, overwrite the returned length; if any allocation
	fails, unwind other allocations and restore the NULL pointer before
	returning NULL.

* nih/string.c (nih_str_array_copy, nih_str_array_append): Add a
	couple of functions to copy a string array, and to append one onto
	the end of another.  Saves reimplementing this each time.
	* nih/string.h: Add prototypes.
	* nih/tests/test_string.c (test_array_copy, test_array_append):
	Test the new functions.

2007-04-24  Scott James Remnant  <scott@netsplit.com>

* nih/string.c (nih_vsprintf): Add va_end to va_copy; C standard
	says so.

2007-03-13  Scott James Remnant  <scott@netsplit.com>

* nih/tests/test_io.c (test_get_family): The elmos of this world
	like to disable various networking protocols, so expect that and
	skip test cases.

* nih/io.h: Change int_data type to a plain old int; there's no
	reason for it to be a fixed width type, and we may as well think
	about supporting ILP64 in case someone does something silly one day.

2007-03-11  Scott James Remnant  <scott@netsplit.com>

* m4/compiler.m4: Don't check for __thread unless --enable-threading
	given to configure, instead define it to empty.

* TODO: Update.

2007-03-09  Scott James Remnant  <scott@netsplit.com>

* nih/logging.c: Make the current log priority available globally
	through the nih_log_priority variable.
	* nih/logging.h: Update.

2007-03-08  Scott James Remnant  <scott@netsplit.com>

* nih/macros.h (_n): Add a macro to wrap ngettext() for plural forms.

2007-03-02  Scott James Remnant  <scott@netsplit.com>

* nih/tests/test_watch.c: Skip these tests if inotify is not
	available, since there's not much we can do.

2007-02-16  Scott James Remnant  <scott@netsplit.com>

* nih/tree.c (nih_tree_next, nih_tree_prev): Add non-recursive
	functions to iterate a tree in-order either forwards or backwards.
	* nih/tree.h (NIH_TREE_FOREACH): Standard macro for wrapping
	nih_tree_next and turning it into a for loop.

	* nih/libnih.h: Include tree.h
	* nih/Makefile.am (libnih_la_SOURCES): Build and link tree.c
	(nihinclude_HEADERS): Install tree.h
	(TESTS): Build and run binary tree test suite.
	(test_tree_SOURCES, test_tree_LDFLAGS, test_tree_LDADD): Details for
	binary tree test suite binary.

2007-02-15  Scott James Remnant  <scott@netsplit.com>

* nih/watch.c (INOTIFY_EVENTS): Use IN_CLOSE_WRITE instead of
	IN_MODIFY; since that guarantees the file has actually been closed,
	and is probably on the filesystem now.

2007-02-13  Scott James Remnant  <scott@netsplit.com>

* nih/signal.c: Add SIGUNUSED to the list of signals that might not
	exist.

* nih/tests/test_option.c (test_parser): gcc doesn't like using
	variables inside fixed for loops, so initialise it deliberately.
	* nih/tests/test_command.c (test_help): Was mistakenly repeatedly
	opening output.
	(test_parser): Similar for loop issue.

* nih/signal.c: Update signal name list, some signals don't exist on
	sparc and some turn up unexpectedly.

2007-02-11  Johan Kiviniemi  <johan@kiviniemi.name>

* nih/hash.h (NIH_HASH_FOREACH, NIH_HASH_FOREACH_SAFE): Added missing
	parenthesis around hash, in case it's a complicated expression with
	unsurprising precedence results.

2007-02-11  Scott James Remnant  <scott@netsplit.com>

* nih/config.c (nih_config_skip_whitespace): It turns out that when
	parsing, it's often useful to skip any whitespace while retaining the
	"step over newlines" behaviour.  Seperate it out into its own 
	function.
	(nih_config_next_token): Call the new function.
	* nih/config.h: Add prototype.
	* nih/tests/test_config.c (test_skip_whitespace): Check the function

* nih/config.c: Remove macro definitions
	* nih/config.h: and make them public instead
	* nih/tests/test_config.c: Use macros.

* nih/config.c (nih_config_next_token): Strange hybrid function,
	it behaves like next_arg() but accepts the same arguments as token();
	it skips whitespace, but only if the initial whitespace character is
	in the delim argument.
	(nih_config_next_arg): This becomes a wrapper around next_token.
	* nih/config.h: Add prototype.
	* nih/tests/test_config.c (test_next_token): Check the new function.

* nih/config.c (nih_config_next_token): Rename to nih_config_token,
	since this doesn't behave like the next_arg() function, and we want
	a similar token function that behaves like that.
	* nih/config.h: Update.
	* nih/tests/test_config.c (test_next_token): Rename and update.

2007-02-09  Scott James Remnant  <scott@netsplit.com>

* nih/hash.h (NIH_HASH_FOREACH_SAFE): Oops, s/list/hash/

* nih/hash.h (NIH_HASH_FOREACH, NIH_HASH_FOREACH_SAFE): Add macros
	to iterate over an entire hash table.
	* nih/tests/test_hash.c (test_foreach, test_foreach_safe): Test the
	macros.

* nih/hash.c (nih_hash_string_key): Add a useful function to return
	the first member after the list header.
	* nih/hash.h: Add prototype.
	* nih/tests/test_hash.c (test_string_key): Add test case.

* nih/file.c (nih_file_is_packaging): Check for common packaging
	filenames -- I swore I wrote this, but I can't find it.
	(nih_file_ignore): Ignore packaging files.
	* nih/file.h: Update.

	this one saves duplicating allocs, which is always messy.
	(nih_str_array_addn): Wrap around the above function.
	(nih_str_array_add): Make this a wrapper around addp instead.
	* nih/string.h: Update.

* nih/string.c (nih_vsprintf): Make sure vsnprintf never returns

	for watch test suite binary.

* nih/file.c: Strip out anything related to inotify, leaving us
	with just three functions; nih_file_map(), nih_file_unmap() and
	nih_dir_walk().  Others that will turn up here will be matching
	and filtering functions.
	* nih/file.h: Strip out typedefs, structures and prototypes for

	of malloc calls.
	* nih/tests/test_child.c (test_add_watch): Use TEST_ALLOC_FAIL
	and call nih_child_poll() first to not debug the init function
	(test_poll): Remove race conditions by making sure the signal
	has reached the child using waitid().  Test the "child we don't

	reading a configuration file because we run out of memory; it's not
	that important.
	* nih/io.c (nih_io_get): Catch failure to remove the string, and
	don't remove the delimiter if that happens.
	(nih_io_printf): Fix doc, this returns zero, not a length.
	* nih/io.h: Fix prototype of nih_io_printf
	* nih/logging.c (nih_log_message): Potentially failing message output
	is crazy; loop until the alloc succeeds.
	* nih/option.c (nih_option_handle): Free the options and arguments

	taking care of issues such as re-organising of the directory structure
	without ending up with duplicate watches.

* nih/config.c: Allow all functions to be called with a zero length
	file, we're completely guarded against pos going past the length,
	so this cannot be a bad thing.  Plus this allows zero-length tokens
	to be extracted trivially.
	(nih_config_next_arg): Raise an error if called in a position where
	there is no argument.  If you want to speculatively check for args,
	peek first.

	of configuration stanzas to be built up.
	* nih/config.c (nih_config_parse_args): Split argument parsing into
	(nih_config_next_arg): This new function that wraps next_token and
	also skips following whitespace.
	(nih_config_next_line): Another new function that skips to the end
	of the line, replacing severael copies of this code.
	(nih_config_get_stanza): Simple function to find a stanza in a table
	by its name.
	(nih_config_parse_stanza): Simple stanza dispatch function; parses an
	argument at the current position, looks it up in the table, then
	calls the function.
	* nih/tests/test_config.c (test_next_arg): Check this function works,
	we know it does because it was covered by other tests, but it's worth
	having its own as well.
	(test_next_line): Check this function works too.
	(test_parse_stanza): Make sure the dispatcher works properly.
	* nih/config.c: Write from the code that was used for upstart,
	making them exported functions to act as a configuration file kit.
	(nih_config_parse_args): Fix a bug where lineno wasn't incremented
	for an embedded newline in between arguments.  Fix another bug where
	a line containing only whitespace or whitespace and a comment would
	hit an assertion - not a problem in practice, but it's a bug.
	* nih/config.h: Function prototypes.
	* nih/libnih.h: Include config.h
	* nih/tests/test_config.c: Write an all new test suite that tests
	the individual parsing functions for their functionality, rather

	(TESTS): Build and run config test suite
	(test_config_SOURCES, test_config_LDFLAGS, test_config_LDADD): Config

	and warn, as we can't just re-use warn as that goes to stderr!
	(nih_message): Change to use the new message level.
	* nih/logging.c (nih_logger_syslog): Output messages at the notice
	level, rather than the warning level.
	(nih_log_init): Change the default priority to message.

	and warning messages go to stderr.
	(test_set_logger, test_set_priority): Reset to the new default.
	* nih/tests/test_option.c (test_quiet, test_verbose, test_debug):

* nih/io.c (nih_io_message_recv): Remove note about the remote end
	being closed; when in message mode, this doesn't usually happen.
	(nih_io_watcher): Only check for a zero length return if we're in
	stream mode, otherwise it just means we got a zero length message.
	(nih_io_watcher_read): Accept zero length messages and return them.
	* nih/tests/test_io.c (test_watcher): Remove tests that tried to
	mix a message-mode io and a dgram socket, that way lies disaster.

* nih/io.c (nih_io_watcher_read, nih_io_watcher_write): Initialise
	len to zero, as valgrind can be fussy about this when we call things
	directly.

* nih/io.h (NihIoMessage): Add a user data field to the message
	structure so we can carry the pid around when queuing notification
	messages in upstart.

2007-01-02  Scott James Remnant  <scott@netsplit.com>

* nih/alloc.h, nih/child.h, nih/command.h, nih/file.h, nih/hash.h:
	nih/io.h, nih/logging.h, nih/main.h, nih/option.h, nih/signal.h:
	nih/timer.h: Give names for all arguments in function pointer typedefs
	so the documentation strings make more sense.

* nih/test.h (TEST_EQ_MEM, TEST_NE_MEM): Cast argument for number
	of bytes to size_t.

2006-12-29  Scott James Remnant  <scott@netsplit.com>

* nih/errors.h: Drop the NIH_IO_MESSAGE_TRUNCATED error.

* nih/io.h (NihIoMessage): Rename msg_buf member to data, and change

	* nih/io.c: Update references to NihIoMessage members.
	(nih_io_message_push_control): Rename to nih_io_message_add_control
	(nih_io_message_add_control): Rewrite to add the control message

	(nih_io_message_recv): After receiving the message, extract all
	control messages and put them into the array.
	(nih_io_message_send): Take control messages from the array into a
	single buffer and send them.

* nih/tests/test_io.c: Update references to NihIoMessage members.
	(test_message_new): Check that the control member is initialised to
	a one-element array containing NULL.
	(test_message_push_control): Rename to test_message_add_control.
	(test_message_add_control): Check the array is extended.

* nih/io.c (nih_io_message_recv): Loop over a call to recvmsg() with
	MSG_PEEK in its arguments to avoid ever returning truncated messages.
	* nih/tests/test_io.c (test_message_recv): Adjust test for truncated
	messages to make sure they do in fact work.
	(test_watcher): Remove the oversized message error check.

2006-12-21  Scott James Remnant  <scott@netsplit.com>

* nih/tests/test_option.c (test_verbose): Add missing call to free
	args.

* nih/io.c (nih_io_message_send): Change to return the ssize_t
	received from sendmsg(), rather than an int.
	(nih_io_watcher_read): Move read functionality out of
	nih_io_watcher into a separate function that can deal with both
	stream and message mode.
	(nih_io_watcher_write): Move write functionality out of nih_io_watcher
	into a separate function that can deal with both stream and message
	mode.
	(nih_io_watcher): Call the separate functions, and handle calling
	the reader when in message mode.  In addition, we now check the
	error code when writing to a socket as well; there are useful errors
	there (like ECONNREFUSED).
	* nih/io.h: Update prototype of nih_io_message_send.
	* nih/tests/test_io.c (test_message_send): Update return checks.
	(test_watcher): Test that the error handled can now be called when
	writing data to a socket, as well as just when reading.  Test
	message mode behaviour.

* nih/io.c (nih_io_send_message): Watch socket for writability.
	(nih_io_write): Extend this function to work in message mode;
	it allocates a new message, stores the data in that buffer, and
	adds it to the send queue.
	(nih_io_printf): Remove restriction that this only be called in
	stream mode; the fact this calls nih_io_write is sufficient to
	ensure correct behaviour.
	* nih/tests/test_io.c (test_send_message): Check that we're testing
	for writability.
	(test_write): Test that this works in message mode.
	(test_printf): Check that this works too, even though this only
	really calls nih_io_write.

* nih/io.c (nih_io_get): Extend so that this can operate in message
	mode on the oldest message in the queue.
	* nih/tests/test_io.c (test_get): Check that this works properly
	in message mode; complete with shutdown check.

* nih/io.c (nih_io_message_new): Do not assign a default list
	destructor, it's not in a hidden list and there are bad consequences
	of freeing a child with a default destructor if the list its in gets
	freed first; new rule - default destructors only if the list is hidden
	and never freed!
	(nih_io_closed, nih_io_shutdown): Don't call the close handler if
	the structure is already marked to be closed; there seems little
	point, and we could accidentally call it multiple times.
	(nih_io_read_message, nih_io_read, nih_io_get): Check whether we
	need to shutdown the socket here, in case the watcher isn't polled
	again.
	* nih/tests/test_io.c (test_shutdown): Check that shutdown works

	(test_read_message, test_read, test_get): Check that a shutdown
	socket is closed when these are called.

2006-12-20  Scott James Remnant  <scott@netsplit.com>

* nih/io.c (nih_io_read): Extend so that it can be called in
	message mode, it reads from the first message until it has been
	exhausted; at which point it frees the message and the next call
	would read from the next.
	* nih/tests/test_io.c (test_read): Check that the new functionality
	works properly.

* nih/io.c (nih_io_first_message): Simple static function to obtain
	the oldest message in the receive queue.
	(nih_io_read_message, nih_io_send_message): Functions to take the
	oldest message out of the receive queue and append a message to the
	send queue.
	* nih/io.h: Add prototypes.
	* nih/tests/test_io.c (test_read_message, test_send_message): Check
	the new functions do what they say on the tin.

General clean-up of nih_io, fixing a few API issues and making it
	more suitable for using in message mode.

* nih/io.c (nih_io_buffer_pop, nih_io_buffer_shrink): Remove the
	silly restrictions that these cannot be called with a length greater
	than the buffer size, instead just truncate it to the buffer size.
	(nih_io_buffer_pop): Length is now updated to the actual number of
	bytes being returned.
	(nih_io_message_add_control): Rename to nih_io_message_push_control.
	(nih_io_message_recv): Change the len parameter to a pointer that's
	updated with the actual number of bytes read.
	(nih_io_stream_watcher): Rename back to nih_io_watcher.
	(nih_io_reopen): Use a single watcher function again, initialise close
	to NULL.  Treat failure to set a descriptor non-blocking as a failure
	to open; otherwise we'll end up screwing up the main loop.
	(nih_io_watcher): Remove the restriction that this is only called
	when in the stream mode.  Leave data in the receive buffer if there's
	no reader function, it's now valid to query the buffer size and read
	by other means.  Catch the ENOMEM error and ignore it.  Set and keep
	an eye on the structure close member, if it is TRUE before we return,
	close the socket.  This also means we check for shutdown sockets in
	the case of error, which we probably should have done.
	(nih_io_maybe_shutdown): Rename to nih_io_shutdown_check.
	(nih_io_close): If the close member of the structure is not NULL
	we're inside a watcher function, so need to set the variable this
	points to to TRUE instead of closing or freeing the structure.
	(nih_io_read): Change the len parameter to be updated with the
	actual number of bytes being returned.
	* nih/io.h: Renamed function prototype.  Updated documentation for
	function typedefs to clarify that they may all call nih_io_close,
	but may not call nih_free.
	* nih/errors.h: Rename NIH_TRUNCATED_MESSAGE to
	NIH_IO_MESSAGE_TRUNCATED, we should probably namespace these.
	* nih/tests/test_io.c (test_buffer_pop, test_buffer_shrink): Check
	that we can pop or shrink the entire buffer if we ask for more.
	(test_message_add_control): Rename to test_push_control.
	(test_message_recv): Check that the cases of remote end closed,
	error received or truncated message are handled properly.
	(test_message_send): Check that an error is handled.
	(test_stream_watcher): Rename back to test_watcher.
	(test_reopen): Check that the socket is not being shutdown or closed.
	(test_shutdown): Drain the buffer before calling handle on it, as
	it's not done automatically now.
	(test_close): Check that a lazy close is performed if io->close is
	not NULL.
	* nih/file.c (nih_file_reader): Update call to nih_io_read.

* nih/logging.h (nih_assert_notreached): Rename to
	nih_assert_not_reached, this was annoying me.

* nih/io.c (nih_io_read, nih_io_write, nih_io_get, nih_io_printf):
	Ensure the NihIo structure is in stream mode; as these only really
	make sense if there's a limitless buffer.

* nih/tests/test_io.c (test_shutdown): Make sure the socket is
	shut down immediately.
	* nih/io.c (nih_io_shutdown): Bugfix, should close the socket
	immediately if there's nothing in the queue, otherwise it may
	hang around forever if it never polls.

* nih/io.c (nih_io_reopen): Receive the type from the arguments,
	instead of hard-coding to be stream.  Set up the structure accordingly.
	* nih/io.h: Update prototype.

	properly.
	* nih/file.c (nih_file_init): Open in stream mode.

* nih/io.c (nih_io_message_new): Catch failure to allocate message
	or control buffer.
	(nih_io_message_add_control): No need to try and allocate the control
	buffer here.
	(nih_io_message_recv): Only need to resize the buffers here as well.
	(nih_io_message_send): No need to deal with there being no message
	or control buffer here either.

	works properly.

	the buffer once done to save on memory.
	(nih_io_buffer_pop, nih_io_stream_watcher): No need to explicitly
	resize here now, as it gets called from shrink.

	* nih/tests/test_io.c (test_buffer_shrink): Test shrink.

* nih/io.c (nih_io_message_recv, nih_io_message_send): Functions

	that we can send and receive messages by using socket pairs.
	(test_get_family): Check that we can get the families of the standard
	three socket types.

2006-09-13  Scott James Remnant  <scott@netsplit.com>

* nih/child.c (nih_child_poll): Zero the siginfo_t struct before
	every call to waitid(), the kernel doesn't do it for us when

	memory condition while extending the buffer so that we just return
	to be called again rather than end up performing some random action.

2006-08-24  Scott James Remnant  <scott@netsplit.com>

* nihify (src_dir): Also copy m4/Makefile.am

* nih/file.c (nih_file_remove_watch): Raise the error before
	performing other actions so errno is not lost.

2006-08-18  Scott James Remnant  <scott@netsplit.com>

* TODO: Update.

* nih/main.h (nih_main_init_gettext): Macro that expands to the
	usual gettext initialisation spiel if ENABLE_NLS is set, or nothing
	if not.
	(nih_main_init): Expand nih_main_init_gettext as well, we almost
	always want to do that, after all.
	* nih/macros.h: Include locale.h if ENABLE_NLS is set, as that
	contains setlocale, amongst other things.

2006-08-14  Scott James Remnant  <scott@netsplit.com>

* nih/alloc.c (nih_realloc): Yet another fix to realloc, we
	forgot to reinitialise our entry in the parent's children list in
	the case of no parent.  After fixing this and tracing the code, I
	realised that the previous fix was inelegant and there is a way to
	deal with children without modifying the pointers until after the
	reallocation.  Documented the reasoning in the function.

* nih/io.c (nih_io_reopen): Report on the error rather than just
	suppressing it.
	(nih_io_error): Likewise, report on the error.

2006-08-12  Scott James Remnant  <scott@netsplit.com>

* nih/main.c (nih_main_loop_close): Drop this function
	(nih_main_loop): Instead mark them close on exec.
	* nih/main.h: Update.

* nih/main.c (nih_main_loop): Change the main loop to use select
	instead of poll, as its semantics are a lot easier to deal with.
	We also use allow select to be interrupted by writing to a pipe
	from the signal handlers, for when Linux gets around to supporting
	SA_RESTART properly.
	(nih_main_loop_interrupt): Write to the pipe so the select call gets
	interrupted.
	(nih_main_loop_exit): Interrupt the main loop, in case we're
	waiting forever.
	(nih_main_loop_close): Close the interrupt pipe, used in children.
	* nih/main.h: Update.
	* nih/io.c (nih_io_add_watch): Change type of events parameter.
	(nih_io_poll_fds): Remove this function.
	(nih_io_select_fds): And replace with this that sets the select
	file descriptor sets instead.
	(nih_io_handle_fds): Now receives select file descriptor sets, and
	becomes rather more obvious in the process.  Restore the previous
	behaviour where a callback isn't called unless requests events
	occur.
	(nih_io_reopen): Always poll for reading so we pick up errors.
	(nih_io_cb): Change type of events parameter and events settings.
	(nih_io_write): Change event settings.
	* nih/io.h: Update.
	(NihIoEvents): replace the previous poll events with a new enum.
	* nih/signal.c (nih_signal_handler): Interrupt the select call in
	the main loop.
	* nih/tests/test_io.c: Update with new test cases.

* nih/tests/test_io.c (test_buffer_push, test_write): Correct
	uninitialised return value.

	to clean up the poll fds list.

* nih/io.c (nih_io_handle_fds): Always call the callback, even if
	unexpected events happen, otherwise we'll miss ERR, HUP, etc.
	(nih_io_shutdown): Allow a socket to be closed lazily, so we can
	send (or receive) a whole bunch of stuff and expect the structure to
	go away afterwards.
	(nih_io_cb): If the shutdown flag has been marked and we run out
	of things in either buffer, act as if one end was closed.
	(nih_io_reopen): Mark sockets as not shutdown by default.
	* nih/io.h: Update.
	* nih/tests/test_io.c (test_shutdown): Test behaviour.
	(test_handle_fds): Take out some of the tests due to changed
	behaviour.  While "clever" I think overall this is undesirable.

* nih/io.c (nih_io_set_cloexec): Function to set the FD_CLOEXEC flag.
	* nih/io.h: Update.
	* nih/tests/test_io.c (test_set_cloexec): Test the function.

2006-08-11  Scott James Remnant  <scott@netsplit.com>

* nih/alloc.h, nih/child.h, nih/hash.h, nih/logging.h, nih/signal.h,
	nih/timer.h: Document arguments to function pointers.

* nih/io.c: Add a whole bunch of code to provide us with a high-
	throughput, async file/socket layer; largely copied from the
	dircproxy code (well, it works!).  This allows read and write calls
	to happen inside the main loop based on whenever poll thinks either
	is possible, while user space can just write what it likes or get
	called when there's data in the recv buffer.
	* nih/io.h: Add the new typedefs, structures and prototypes.
	* nih/tests/test_io.c: Lots of test cases for this stuff.

2006-08-10  Scott James Remnant  <scott@netsplit.com>

* nih/alloc.c (nih_realloc): Fix a fairly critical bug, we weren't
	dealing with the fact that the children list head can move;
	do some fancy shifting to make that work.

* nih/string.c (nih_str_split): Add a function to split a string
	based on delimiters into an array.
	* nih/string.h: Update.
	* nih/tests/test_string.c (test_str_split): Test the new function.

* nih/errors.h: Include errno.h for helpfulness.

2006-08-03  Scott James Remnant  <scott@netsplit.com>

	a parent for the watch.
	* nih/io.h: Update.
	* nih/tests/test_io.c: Update.

* nih/signal.c (nih_signal_add_callback): Give this the same treatment,
	it takes the parent for the signal callback.

	* nih/tests/test_signal.c: Update.

* nih/timer.c (nih_timer_add_timeout, nih_timer_add_periodic) 
	(nih_timer_add_scheduled): Use nih_alloc properly by taking a parent
	for the timer object and setting a destructor on it so that it's
	automatically removed when the parent is freed.
	* nih/timer.h: Update.
	* nih/tests/test_timer.c: Update function calls.
	* nih/tests/test_main.c (test_main_loop): Update also.

* nih/list.c (nih_list_destructor): Add a destructor function that
	just cuts the entry out of the list in preperation for being freed.
	* nih/list.h: Update.
	* nih/tests/test_list.c (test_destructor): Test the behaviour of
	the new function.

* nih/tests/test_error.c: Include fixes.

2006-08-02  Scott James Remnant  <scott@netsplit.com>

* nih/signal.c (nih_signal_set_handler, nih_signal_set_default) 
	(nih_signal_set_ignore): Reset sa_flags so that we don't pass
	uninitialised data for SIGALRM.
	(nih_signal_reset): Add function to reset signals back to their
	default state.
	* nih/signal.h: Update.
	* nih/tests/test_signal.c (test_reset): Add test case.

* nih/error.c (nih_error_raise_system): Be a lot more careful in
	this function!  Save the value of errno in case we overwrite it
	and call nih_error_init()

* nih/signal.c (nih_signal_set_handler): Add the SA_NOCLDSTOP
	signal for SIGCHLD.

* nih/main.c (nih_main_loop): Drop the code that masked out the
	child signal, it was inherently racy and there's no particular
	reason to do it anyway since we use SA_RESTART in signal.c for
	most things.

* nih/signal.c (nih_signal_set_handler, nih_signal_set_default)
	(nih_signal_set_ignore): don't set SA_RESTART for SIGALRM.

	(nih_signal_set_ignore): use nih_return_system_error to make the
	code rather cleaner.

	(nih_return_system_error): Add additional useful function.
	* nih/tests/test_error.c (test_return_system_error): Add test
	case for the new macro.

* nih/child.c (nih_child_poll): Convert to use waitid() so that
	we can obtain the information about the dead child without reaping
	it until we're done processing; useful because it means /proc/$PID
	and the child itself is still around during the handlers.
	* nih/child.h (NihReaper): Gains a new third argument that indicates
	whether the child exited normally or was killed.
	* nih/tests/test_child.c (test_poll): Update.

* nihify: Add a few useful sanity checks so that it works with
	relative paths and already-nihified directories.

* m4/misc.m4: Remove older force code.

* TODO: Updated.

* m4/Makefile.am (dist_aclocal_DATA): Distribute misc.m4, long
	missed.

* nihify: Add useful script for symlinking into source trees until

	* nih/main.h: Update.
	* nih/tests/test_main.c (test_main_loop): Add a trivial test case
	for the main loop, it's damned difficult to test, but at least this
	ensures the bases are touched.

	nih_signal_init()
	* nih/child.c (nih_child_poll): Add missing call to nih_child_init()
	* nih/io.c (nih_io_poll_fds, nih_io_handle_fds): Add missing calls

	* nih/tests/test_io.c: Test cases for I/O watches.

	(NihAllocCtx): Add new allocator member to store the allocator used,
	so we free with the right one.

	(nih_list_new): Use nih_list_init() to initialise the list.
	(nih_list_new): Use nih_list_init() to re-initialise the list
	to a single-member.
	* nih/list.h: Add prototype for nih_list_init.
	(NihListIter): Remove the iterator structure, it turns
	out to be harder work to try and use lists in an "all nodes are
	interesting" manner; so we'll iterate them normally instead.
	(NIH_LIST_FIRST, NIH_LIST_LAST): Remove iterator test functions.
	(NIH_LIST_PREV, NIH_LIST_NEXT): Remove iterator change functions.
	* nih/tests/test_list.c: Use NULL for nih_list_new in all functions.
	(test_init): New test case for nih_list_init().
	(test_iterator): Removed iterator tests.

	* nih/list.h: Prototypes and macros.
	* nih/macros.h: Some generic macros.
	* nih/libnih.h: Header to import everything.
	* nih/tests/test_list.c: Test-cases for linked-list code.
	* nih/Makefile.am (libnih_la_SOURCES): Link list.c in.
	(nihincludedir): Define directory to contain header files to be
	$includedir/nih.

	(nihinclude_HEADERS): Install header files.
	(TESTS): Build and run the list test-cases.
	(test_list_SOURCES, test_list_LDADD): Identify the test sources and
	objects it needs.

* nih/libnih.ver: Add simple "everything beginning nih_* is global"
	version script.
	* nih/Makefile.am (libnih_la_LDFLAGS): Use the version script
	if we can pass an argument to do that to the linker.
	(EXTRA_DIST): Distribute the version script.

* m4/compiler.m4 (NIH_COMPILER_WARNINGS): Macro to add -Wall,
	-Werror and -pedantic to CFLAGS and CXXFLAGS if using gcc or g++.
	(NIH_COMPILER_OPTIMISATIONS): Macro to remove any optimisation
	arguments from CFLAGS and CXXFLAGS and replace them with -O0 to
	override any default level.
	(NIH_COMPILER_COVERAGE): Macro to add compiler coverage testing
	arguments to CFLAGS and CXXFLAGS.
	* m4/linker.m4 (NIH_LINKER_OPTIMISATIONS): Macro to add -Wl,-O1
	to LDFLAGS to increase the optimisation of the linker hash tables.
	(NIH_LINKER_VERSION_SCRIPT): Macro to test for the right argument
	to pass a version script to the linker and define
	HAVE_VERSION_SCRIPT and VERSION_SCRIPT_ARG.
	* m4/Makefile.am (dist_pkgdata_DATA): Ship macros.
	* configure.ac: Use new macros.

* ChangeLog: Initial project infrastructure created.
