2011-07-14  Kjell Ahlstedt  <kjell.ahlstedt@bredband.net>

	slot_rep: Avoid access to deleted object in notify().

	* sigc++/functors/slot_base.cc: slot_rep::notify() calls disconnect() before
	destroy(). If disconnect() has deleted the slot_rep object, destroy() is not
	called. Bug #564005.

2.2.9:

2011-02-22  Kjell Ahlstedt  <kjell.ahlstedt@bredband.net>

	trackable: Avoid calling the same callback function twice

	* sigc++/trackable.cc: Invalidate a callback function entry in
	trackable_callback_list::remove_callback() when the list is being cleared.
	Bug 589202.

2011-02-04  Kalev Lember  <kalev@smartlink.ee>

	Fix the build with GCC 4.6

	* sigc++/signal_base.h: Include <cstddef> for size_t.

2010-10-12  David King  <davidk@openismus.com>

	Documentation changes

	* *.h.m4: Minor changes to documentation to fix up code example
	formatting, by removing the additional two spaces of indentation.
	Additionally, fix some spelling and grammar mistakes and typos.

2010-06-05  David King  <davidk@openismus.com>

	Small website updates

	* docs/index.html: Remove broken namespace links.
	* docs/website/doc.shtml: Link to library.gnome.org tutorial and API
	reference.

2.2.8:

2010-06-04  Murray Cumming  <murrayc@murrayc.com>

	Manual: Add an id="index" attribute in case that helps library.gnome.org.

	* docs/manual/libsigc_manual.xml: Add it to the <book> tag.

2.2.7:

2010-05-04  Murray Cumming  <murrayc@murrayc.com>

	Documentation improvements.

	* docs/manual/libsigc_manual.xml: Remove Marshallers section because
	it is apparently outdated and there is no example code to test it.
	This fixes bug #417924 (Michael Ekstrand)
	* sigc++/sigc++.h: Main page text: Rearranged slightly.

2010-04-27  David King  <davidk@openismus.com>

	Improvements to main page documentation

	* sigc++/sigc++.h: Minor improvements.

2010-04-23  David King  <davidk@openismus.com>

	Add main page to Doxygen documentation

	* docs/Makefile.am: Parse sigc++/sigc++.h for documentation.
	* sigc++/sigc++.h: Add main page to Doxygen documentation.

2010-04-23  David King  <davidk@openismus.com>

	Fix the functors Doxygen group in the m4 files

	* sigc++/functors/macros/functor_trait.h.m4:
	* sigc++/functors/macros/mem_fun.h.m4:
	* sigc++/functors/macros/ptr_fun.h.m4: Rename functors to
	sigcfunctors.

2.2.6:

2010-04-16  Murray Cumming  <murrayc@murrayc-desktop>

	Docs: Fix the functors group and the link from the overview.

	* docs/website/doc.shtml: Revert this to point to the overview page at
    docs/indeex.html, which I have manually uploaded to the website, until
    we add this overview to the doxygen-generated documentation itself.
	* sigc++/functors/slot_base.h:
	* sigc++/visit_each.h: Rename the functors doxygen group to sigcfunctors,
    because doxygen seems to confuse it with the one in libstdc++.
	* docs/index.html: Update the links.

2010-04-16  Murray Cumming  <murrayc@murrayc.com>

    Website: Fix the Makefile so upload works with sourceforge again.

2010-04-06  Murray Cumming  <murrayc@murrayc.com>

    Website: Update the reference API link.

	* docs/website/doc.shtml: Update the reference API link to use
    library.gnome.org. We should make sure that the tutorial docbook is there
    too.
    * docs/website/devel.shtml: Remove CVS-specific instructions, quickly
    mentioning the git module instead.
    However, the Makefile must be updated to cope with sourceforge's changes.
    I was not able to upload this yet.

2.2.5:

2010-01-05  Daniel Elstner  <daniel.kitta@gmail.com>

	Use non-blurry font for dot graph labels

	* docs/reference/Doxyfile.in (SHOW_INCLUDE_FILES): Enable.
	(SHOW_USED_FILES): Disable.
	(DOT_FONTNAME): Change from FreeSans to Sans, as the hinting for the
	former appears to be rather bad.
	(TEMPLATE_RELATIONS): Disable to reduce noise.

2009-12-29  Krzysztof Kosiński  <tweenk.pl@gmail.com>

	Accumulators: Allow return types that are different to the signal's.

	* sigc++/macros/signal.h.m4: signal_emit*: Correct the slot_iterator_buf_type
	and slot_reverse_iterator_buf_type typedefs to allow accumulators with
	return types that are different to the signal's return type.
	* tests/Makefile.am: Reenable test_accumulated, so we can test the fix.
	It should be manually disabled if building on AIX (if the AIX problem cannot
	be fixed properly).
	* tests/test_accumulated.cc: Add an accumulator with a return type that is
	different to the signal's return type. In this case it's a vector listing
	all results.
	Bug #586436.

2009-12-27  Daniel Elstner  <daniel.kitta@gmail.com>

	Disable collaboration graphs in documentation

	* docs/reference/Doxyfile.in (CLASS_DIAGRAMS): Enable.  Contrary to
	what the Doxygen documentation says, no dot class inheritance graphs
	will be generated if both CLASS_DIAGRAMS and COLLABORATION_GRAPH are
	set to NO.
	(COLLABORATION_GRAPH), (GROUP_GRAPHS): Turn off additional graphs to
	reduce the noise.

2009-10-26  Armin Burgmeier  <armin@arbur.net>

	* sigc++config.h: Move the first five definitions to the !SIGC_MSC
	ifdef block, so MSVC does not see them and only uses the definitions
	from the SIGC_MSC block. This fixes the build with MSVC.

2009-09-19  Daniel Elstner  <daniel.kitta@gmail.com>

	Support Automake silent rules

	* configure.ac: Call the AM_SILENT_RULES macro if it is defined.
	* docs/doc-manual.am, sigc++/Makefile.am: Prefix the commands of
	custom rules with $(AM_V_GEN) or $(AM_V_at) in order to support
	the silent rules feature of Automake.

2009-09-17  Michael Hasselmann  <michaelh@openismus.com>

	Documentation cleanup: sigc::hide() always only hides one signal argument

	* sigc++/adaptors/macros/hide.h.m4: The documentation stated that sigc::hide()
	could discard multiple signal arguments when in fact the whole API only allows
	control over one (dummy) signal argument at a time. The  "multiple argument
	hiding" example lives in it own section now to make it clearer you have to nest
	sigc::hide() for that.

2009-09-13  Daniel Elstner  <daniel.kitta@gmail.com>

	Enable verbose output of autoreconf

	* autogen.sh: Pass --verbose option to autoreconf.

2.2.4.2:

2009-09-02  Daniel Elstner  <danielk@openismus.com>

	Bump version to 2.2.4.2 and update NEWS

	* configure.ac (AC_INIT): Increment version number to 2.2.4.2.
	(MM_PREREQ): Require mm-common 0.7.2.
	* NEWS: Write news entry for libsigc++ 2.2.4.2.

2009-09-02  Daniel Elstner  <danielk@openismus.com>

	Document namespace sigc briefly

	* sigc++/signal_base.h (sigc): Prepend documentation comment to
	provide a brief description of namespace sigc, so that Doxygen
	will recognize the namespace as documented.

2009-08-31  Daniel Elstner  <danielk@openismus.com>

	Update Doxygen configuration for Doxygen 1.6.1

	* docs/reference/Doxyfile.in: Update configuration template using
	Doxygen 1.6.1.
	(SORT_MEMBERS_CTORS_1ST): Enable.

2009-08-31  Daniel Elstner  <danielk@openismus.com>

	Protect space after comma in M4 output

	* sigc++/macros/template.macros.m4 (_LOOP_SEP): Triple-quote the
	list separator in this hairy construct, since the macro definition
	itself is not quoted at all and the space after the comma got lost
	in the output.  This, in turn, produced overlong lines in the HTML
	reference documentation.

2.2.4.1:

2009-08-28  Daniel Elstner  <danielk@openismus.com>

	Update news entry for libsigc++ 2.2.4.1 release

	* NEWS: Update top entry for release 2.2.4.1 of libsigc++.
	(2.2.4): Correct spelling of Frédéric Péters' name.

2009-08-27  Daniel Elstner  <danielk@openismus.com>

	Use shared mm-common Doxygen style sheet

	* configure.ac (MM_PREREQ): Require mm-common 0.7.
	* docs/Makefile.am (dist_noinst_DATA): List doxygen.css.
	* docs/reference/Doxyfile.in (HTML_STYLESHEET): Assign path
	to the shared doxygen.css provided by mm-common.

2009-08-27  Daniel Elstner  <danielk@openismus.com>

	Remove header and footer HTML fragments

	* docs/reference/libsigc_{header,footer}.html_fragment: Delete
	files.  These custom fragments were an unnecessary maintenance
	hassle.  Also, the files were out of date with respect to the
	encoding and CSS classes used by Doxygen.
	* docs/reference/Doxyfile.in (HTML_HEADER), (HTML_FOOTER): Set
	to the empty string.
	(PROJECT_NAME): Substitute @PACKAGE_NAME@.
	(PROJECT_NUMBER): Substitute @PACKAGE_VERSION@.  It does look
	nicer in the generated HTML pages, and is probably also less
	confusing.
	(SORT_GROUP_NAMES): Enable for predictability.

2009-08-26  Daniel Elstner  <danielk@openismus.com>

	Bump version to 2.2.4.1 and update NEWS

	* configure.ac (AC_INIT): Increment version number to 2.2.4.1.
	* NEWS: Write news entry for libsigc++ 2.2.4.1.

2009-08-26  Daniel Elstner  <danielk@openismus.com>

	Reenable hierarchy graphs for each class

	* docs/reference/Doxyfile.in (COLLABORATION_GRAPH): Set option
	to YES to enable the per-class inheritance graphs.

2009-08-25  Daniel Elstner  <danielk@openismus.com>

	Have Automake check NEWS and use bzip2

	* configure.ac (AM_INIT_AUTOMAKE): Add options check-news and
	dist-bzip2.

2009-08-25  Daniel Elstner  <danielk@openismus.com>

	Update NEWS for libsigc++ 2.2.4 release

2009-08-25  Daniel Elstner  <danielk@openismus.com>

	Bump version to 2.2.4 and require mm-common 0.6.1

	* configure.ac (AC_INIT): Increase version number to 2.2.4.
	(MM_PREREQ): Require mm-common 0.6.1 for the updated default
	location of the reference documentation.

2009-08-25  Daniel Elstner  <danielk@openismus.com>

	Change documentation host to library.gnome.org

	* README, docs/manual/libsigc_manual.xml: Adjust links to the
	reference documentation in the text.
	* docs/Makefile.am (pubdocbase), (htmlrefpub): Remove override
	and use the updated mm-common default values.
	* sigc++{,-uninstalled}.pc.in (htmlrefpub): Adjust link.

2009-08-24  Daniel Elstner  <danielk@openismus.com>

	Add id="content" element to documentation index

	* docs/reference/libsigc_header.html_fragment: Start <div> element
	with attribute id="content" to match the other C++ binding modules.
	* docs/reference/libsigc_footer.html_fragment: Close <div> element.

2009-08-20  Daniel Elstner  <danielk@openismus.com>

	Use new version component substitutions

	* MSVC_Net200[58]/sigc.rc.in: Replace the no longer defined
	@FP_*_VERSION@ substitutions by the new @SIGCXX_*_VERSION@
	substitutions for the version number components.  These are
	defined by MM_INIT_MODULE() from mm-common.

2009-08-20  Daniel Elstner  <danielk@openismus.com>

	Substitute API version in filenames dynamically

	* sigc++.pc.in: Rename file from sigc++-2.0.pc.in.
	* sigc++-uninstalled.pc.in: Rename file from
	sigc++-2.0-uninstalled.pc.in.
	* MSVC_Net200[58]/sigc.rc.in: Rename files from sigc-2.0.rc.in
	and use @SIGCXX_API_VERSION@ substitution for the API version.
	Also replace @VERSION@ with @PACKAGE_VERSION@.
	* MSVC_Net200[58]/libsigc++2.{sln,vcproj}: Remove version from
	the project name and filenames.
	* MSVC_Net200[58]/filelist.am: Remove version from filenames.
	* configure.ac (AC_CONFIG_FILES): Insert ${SIGCXX_MODULE_NAME}
	into output filenames and remove the version from the input
	filenames.
	* Makefile.am: Use $(SIGCXX_MODULE_NAME) in pkg-config file
	names instead of hard-coding the API version.
	* sigc++/Makefile.am (lib_LTLIBRARIES): Instead of hard-coding
	the libtool archive name, substitute @SIGCXX_API_VERSION@ into
	it, as well as into the derived variable names.

2009-08-17  Daniel Elstner  <danielk@openismus.com>

	Set libtool version information

	* sigc++/Makefile.am (libsigc_2_0_la_LDFLAGS): Add libtool option
	-version-info 0:0:0 to specify the version information explicitly.

2009-08-16  Daniel Elstner  <daniel.kitta@gmail.com>

	Remove unused parameter names for correctness

	* tests/test_copy_invalid_slot.cc, tests/test_custom.cc,
	tests/test_deduce_result_type.cc, tests/test_functor_trait.cc,
	tests/test_limit_reference.cc: Remove the names of unused function
	parameters from the prototype, in order to get libsigc++ to build
	with fatal compiler warnings.

2009-08-16  Daniel Elstner  <daniel.kitta@gmail.com>

	Rename scripts/ to build/ for consistency

	* build/: Rename directory from scripts/ for consistency with most
	of the other modules that switched to the new build infrastructure.
	* Makefile.am (ACLOCAL_AMFLAGS): Adjust M4 include directory.
	* README: Adjust a reference to scripts/ in the text.
	* configure.ac (AC_CONFIG_AUX_DIR): Copy auxiliary files to build/.
	(AC_CONFIG_MACRO_DIR): Place Autoconf M4 files into build/.
	* docs/Makefile.am: Include $(top_srcdir)/build/doc-reference.am.

2009-08-16  Daniel Elstner  <danielk@openismus.com>

	Update for latest mm-common 0.4

	* configure.ac (MM_PREREQ): Require mm-common 0.4.
	(MM_INIT_MODULE): Omit now optional version number argument.
	(MM_CONFIG_DOCTOOL_DIR): Copy the documentation utilities into docs/
	instead of scripts/.

	* docs/Makefile.am (htmlrefpub): ditto.
	(doc_input): Perform a VPATH search for each input file, to correctly
	handle the case of rebuilding the documentation of a tarball release
	which includes the generated sources.
	(dist_noinst_DATA): List documentation utilities.

2009-08-11  Daniel Elstner  <danielk@openismus.com>

	Do not recurse into MSVC subdirectories

	* MSVC_Net200[58]/filelist.am: New Automake include files, defining
	the lists of files to ship from the MSVC project directories.
	* MSVC_Net200[58]/Makefile.am: Delete recursive Makefile.am files.
	* Makefile.am: Include MSVC_Net200[58]/filelist.am.
	(dist_noinst_DATA): Distribute MSVC project files.
	(SUBDIRS): Do not recurse into the MSVC_Net200[58] subdirectories.
	* configure.ac (AC_CONFIG_FILES): Remove the output files
	MSVC_Net200[58]/Makefile.am from the list.
	(AC_CONFIG_COMMANDS): Copy sigc++config.h into the MSVC project
	directories at the end of config.status.

2009-08-11  Daniel Elstner  <danielk@openismus.com>

	Remove now superfluous doctool overrides

	* docs/Makefile.am: Remove overrides for the documentation
	utilities, since MM_CONFIG_DOCTOOL_DIR() already takes care
	of setting MMDOCTOOLDIR to the local directory.
	* sigc++-2.0.pc.in (datadir): Substitute value, just in case.

2009-08-10  Daniel Elstner  <danielk@openismus.com>

	Have mm-common-prepare install the doc utils

	* configure.ac: Call MM_CONFIG_DOCTOOL_DIR([scripts]) to set
	up the destination directory for mm-common-prepare to copy
	the documentation utilities to.
	* scripts/doc-install.pl: Delete file.
	* scripts/doc-postprocess.pl: ditto,
	* scripts/tagfile-to-devhelp2.xsl: ditto.

2009-08-09  Daniel Elstner  <danielk@openismus.com>

	Refresh doc-install and doc-postprocess copies

	* scripts/doc-install.pl, scripts/doc-postprocess.pl: Copy
	latest versions from the mm-common module.
	* docs/Makefile.am (doc_install), (doc_postprocess): Include
	$(PERL) interpreter command in front of the script name.

2009-08-08  Daniel Elstner  <danielk@openismus.com>

	Disable extraction of undocumented identifiers

	* docs/reference/Doxyfile.in (EXTRACT_ALL): Change setting to
	NO, and adapt a number of related options accordingly.  The
	result is a net loss of about 300 generated .html files.  The
	roughly 450 files which remain now are still an insanely high
	number, though.
	(PREDEFINED): Predefine the Autoconf configuration defines to
	nudge Doxygen towards documenting the canonical code paths.

2009-08-07  Daniel Elstner  <danielk@openismus.com>

	Use #error explicitly instead of broken code

	* sigc++config.h.in: Do use the #error preprocessor directive,
	instead of an errornous piece of code.  This code does not need
	the same level of obfuscation as an Autoconf feature test.

2009-08-07  Daniel Elstner  <danielk@openismus.com>

	Change bug report URL to point to Bugzilla

	* configure.ac (AC_INIT): Change the bug-report argument to the
	URL for filing a new libsigc++ bug on bugzilla.gnome.org.  Also
	name the website URL as fifth argument.  It will simply be ignored
	if the installed Autoconf does not support this new feature.

2009-08-07  Daniel Elstner  <danielk@openismus.com>

	Do not enable -pedantic mode by default

	* configure.ac (MM_ARG_ENABLE_WARNINGS): Remove -pedantic from the
	list of compiler flags to use at warning level "min" (the default).

2009-08-07  Daniel Elstner  <danielk@openismus.com>

	Correct M4 forbidden tokens pattern

	* configure.ac (m4_pattern_forbid): Take into account that the
	pattern is applied to tokens, not lines.  Also catch unexpanded
	calls to underscore-prefixed private macros.

2009-08-06  Daniel Elstner  <danielk@openismus.com>

	Transition to new mm-common build infrastructure

	* autogen.sh: Replace with a minimal script that simply executes
	mm-common-prepare, autoreconf and configure.
	* configure.ac: Get rid of an enormous amount of old cruft.  Use
	macros from the new mm-common module to set up Doxygen for building
	the documentation.  Add option to enable more compiler warnings.
	* sigc++-2.0-uninstalled.pc.in: New pkg-config data file to allow
	linking to an uninstalled libsigc++.
	* sigc++-2.0.pc.in: Modernize.  Provide the location of the
	installed reference documentation and the Doxygen tag file.
	* sigc++config.h.in: Modernize and update for new build
	infrastructure.
	* Makefile.am, */Makefile.am: Modernize and adapt to the new C++
	binding build infrastructure in the mm-common module.
	* sigc++/filelist.am: New Automake include file.  Defines lists
	of C++ and M4 source files.
	* docs/Makefile.am: Rewrite using doc-reference.am from the
	mm-common module.
	* docs/doc-manual.am: New Automake include file for building the
	libsigc++ Docbook manual.
	* docs/images/Makefile.am: Remove file.
	* docs/manual/Makefile.am: ditto,
	* docs/reference/Makefile.am: ditto.
	* docs/Makefile_web.am_fragment: Remove for now, to be taken care
	of later.
	* docs/reference/Doxyfile.in: Modernize and adapt to new build
	infrastructure.
	* docs/reference/beautify_docs.pl: Remove and use the more recent
	scripts/doc-postprocess.pl instead.
	* libsigc++-2.0.spec.in: Remove, to be resurrected only if someone
	complains.
	* scripts/Makefile.am: Remove file.  Distribute the files from the
	toplevel Makefile.am instead.
	* scripts/cxx_std.m4: Add missing third argument to AC_DEFINE().
	* scripts/doc-install.pl: New file, copied from mm-common.
	* scripts/doc-postprocess.pl: ditto,
	* scripts/tagfile-to-devhelp2.xsl: ditto.

2008-11-13  Murray Cumming  <murrayc@murrayc.com>

	* docs/website/stable.shtml: Correct the download link so it shows all
	versions, not just 2.0.

2.2.3:

2008-10-08  Armin Burgmeier  <armin@arbur.net>

	* MSVN_Net2005/libsigc++2.vcproj: Changed output name to match the new
	naming convention.

	* MSVC_Net2008/: Added MSVC 2008 project files. These are basically
	the same as for MSVC 2005, but converted to MSVC 2008 projects.

	* configure.ac:
	* Makefile.am: Added the new files to the build.

2008-08-08  Armin Burgmeier  <armin@arbur.net>

	* MSVC_Net2005/libsigc++2.sln: Enable the disconnect_during_emit test
	by default.

	* MSVC_Net2005/libsigc++2.vcproj: Renamed the generated debug database
	file to sigc-2.0d.pdb (the default), to stay consistent with the *mm
	wrapper libraries.

2008-08-08  Armin Burgmeier  <armin@arbur.net>

	* MSVC_Net2005/: Moved from MSVC_Net2003.

	* MSVC_Net2005/libsigc++2.sln:
	* MSVC_Net2005/libsigc++2.vcproj:
	* MSVC_Net2005/tests/*/*.vcproj: Converted the Visual Studio 2003
	project files to 2005 ones.

	* MSVC_Net2005/Makefile.am:
	* Makefile.am:
	* configure.ac: Adapted build files accordingly.

2008-04-06 Cedric Gustin <cedric.gustin@gmail.com>

	* MSVC_Net2003/sigc-2.0.rc.in: Removed ATL/MFC header files
	dependency as afxres.h is not part of the Microsoft Platform
	SDK provided with Visual C++ Express 2008.
	Bug #503933.

2.2.2:

2008-03-10  Deng Xiyue  <manphiz@gmail.com

	* sigc++/macros/slot.h.m4:
	Added an include of functors/slot.h that was mistakenly removed
	during the 2.1 series, apparently breaking API slightly.
	Bug #521418.

2.2.1:

2008-02-28  Elaine Xiong  <elaine.xiong@sun.com>

	* sigc++/macros/signal.h.m4:
	* tests/test_accum_iter.cc: Add ifdefs around uses of
	reverse_iterator to really fix the build with recent
	versions of Sun CC.
	Bug #302098.

2.2.0:

2008-01-01  Ryan Hill  <dirtyepic@gentoo.>

	* tests/test_copy_invalid_slot.cc: Include the cstdlib
	and cstring headers to fix the build with the gcc 4.3
	pre-release. Bug #454882.

2007-08-31  Murray Cumming  <murrayc@murrayc.com>

	* tests/test_copy_invalid_slot.cc: Added some includes to
	fix the build in some environments, such as when using Sun CC.
	Thanks to Vladimir Marek in bug #469872.

2.1.1:

2007-08-14  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/Makefile.am:
	* sigc++/compatibility.h: Removed this header.
	* sigc++/bind.h:
	* sigc++/bind_return.h:
	* sigc++/connection.h:
	* sigc++/macros/class_slot.h.m4:
	* sigc++/macros/hide.h.m4:
	* sigc++/macros/method_slot.h.m4:
	* sigc++/macros/object_slot.h.m4:
	* sigc++/macros/retype.h.m4:
	* sigc++/macros/signal.h.m4:
	* sigc++/macros/slot.h.m4:
	* sigc++/object.h:
	* sigc++/retype_return.h: Removed deprecated
	compatibility API, to probably fix the build with
	some compilers, such as some versions of the Sun Forte C++
	CC compiler. Some of these headers are now mostly empty and
	should be removed later.
	This API has been deprecated April 2004, and
	is not widely used, so it seems safe to do this now.

	* tests/Makefile.am:
	* tests/test_compatibility.cc: Removed this test.

2007-07-28  Michael Elkstrand  <michael@elehack.net>

	* sigc++/macros/signal.h.m4: slot_iterator_buf,
	slot_reverse_iterator_buf: Added typedefs for
	value_type, reference, and pointer, so that these
	iterators are more like standard C++ iterators, so they can
	be used with standard C++ algorithms.
	* tests/Makefile.am:
	* tests/test_accum_iter.cc: Added a test for this.
	Bug #417926.

2006-11-14  Daniel Elstner  <daniel.kitta@gmail.com>

	* autogen.sh: Wholly replace this script with a critter from one
	of my personal projects, with slight modifications.  This one does
	some sophisticated stuff like probing version numbers of available
	automake and aclocal executables, in order to choose the right one
	accordingly.  All this is necessary to make the build system work
	robustly in custom environments such as Maemo where automake-1.9
	doesn't come preinstalled.

2006-06-20  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/adaptors/macros/bind.h.m4:
	* sigc++/adaptors/macros/retype.h.m4:
	* sigc++/functors/macros/functor_trait.h.m4:
	* sigc++/functors/macros/slot.h.m4:
	* sigc++/macros/retype.h.m4:
	* sigc++/macros/signal.h.m4: Revert the previous changes, because none is
	used in the exported symbol names from gtkmm, so this would break the ABI
	of gtkmm.

2006-05-26  Régis Duchesne <hpreg@vmware.com>

	* sigc++/adaptors/macros/bind.h.m4:
	* sigc++/adaptors/macros/retype.h.m4:
	* sigc++/functors/macros/functor_trait.h.m4:
	* sigc++/functors/macros/slot.h.m4:
	* sigc++/macros/retype.h.m4:
	* sigc++/macros/signal.h.m4:
	Renamed 'nil' to 'none' to allow an Objective-C++ compiler to compile
	the library header files.

2005-12-21  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/macros/signal.h.m4: Make remaining
	reverse_iterator_buf operator--() methods
	return by reference, like the operator++() methods.
	Bug #304402 from John Profic.

2005-12-20  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/macros/signal.h.m4: Make all operator--() methods
	return by reference, like the operator++() methods.
	Bug #304402 from John Profic.

2005-12-14  John Profic <profic@kursknet.ru>

	* sigc++/macros/signal.h.m4: Fix compilation problem in
	the last patch.

2005-12-14  John Profic <profic@kursknet.ru>

	* sigc++/macros/signal.h.m4: Added emit_reverse().

This is the HEAD branch, for API/ABI-compatible API additions.
See also the libsigc-2-0 branch.

2005-12-01  Murray Cumming <murrayc@murrayc.com>

	* sigc++/functors/slot_base.cc:
	slot_base::disconnect(): Set call_ to 0,
	to invalidate the slot, even if parent_ is 0.
	I think parent_ is, for instance, a signal, but
	disconnect should still work on a slot that is not
	connected to a signal, because a slot can be invoked
	directly.
	Fixes bug #311057 from James Lin.

2005-12-01  Murray Cumming <murrayc@murrayc.com>

	* tests/Makefile.am:
	* tests/test_slot_disconnect.cc: Added test
	case from bug #311057.

2005-11-16  Philipp Berndt  <philipp.berndt@gmx.net>

	* sigc++/adaptors/macros/exception_catch.h.m4: Make member
	exception_catch_functor<T_functor, T_catcher, void>::catcher_
	public so that it can be accessed by visit_each()
	(bug fixed for generalization on 2004-11-06)

2.0.16:

2005-08-01  Neal E. Coombes  <nealc@trdlnk.com>

 	* sigc++/signal_base.h: Updated the documentation for temp_slot_list
 	as requested in bug #303896.

2005-08-01  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/adaptors/hide.h.m4: Added missing
	) in call to sun_forte_workaround(), fixing
	build on SUN Forte 5.5. Bug #312020.

2005-08-19  Bruno Martinez <brunom@fing.edu.uy>

	* sigc++/type_traits.h: Renamed
	::sigc::is_base_and_derived::internal to
	::sigc::is_base_and_derived::internal_class
	in order to avoid conflict with
	namespace internal.

2005-07-13  Murray Cumming  <murrayc@murrayc.com>

	* docs/manual/libsigc_manual.xml: Correct mentions of
	1.2 stuff instead of 2.0. Patch in bug #310213 from
	pebble.org.uk.

2005-07-13  Murray Cumming  <murrayc@murrayc.com>

	* docs/manual/libsigc_manual.xml: Fixed typo
	found by Antonio Coralles.

2005-07-09  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/macros/signal.h.m4: Did the same (see
	last commit) for slot_const_iterator and
	slot_iterator_buf.

2005-07-09  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/macros/signal.h.m4: slot_iterator:
	operator--() now returns value, not reference, like
	operator++() already did. This caused crashes when
	using --no-inline with g++. Bug #308651 by
	Michael Andres.

2.0.15:

2005-07-04  Philip Langdale  <plangdale@vmware.com>

	* sigc++/adaptors/macros/compose.h.m4: Add a setter typedef to
	compose*_functor and use it instead of the (incorrect) getter
	typedef in the compose* specialization of visit_each<>().
	This corrects the lifetime management of slots created with
	compose(). Bug #308433.

2005-06-13  Marek Rouchal  <marek.rouchal@infineon.com>

	* tests/test_deduce_result_type.cc: Specify int return type
	for main(), to be more ISO C++ compliant. Bug #307478.

2005-06-11  Andris Pavenis <pavenis@latnet.lv>

	* sigc++/adaptors/lambda/macros/base.h.m4:
	* sigc++/adaptors/lambda/macros/select.h.m4
	* sigc++/adaptors/macros/hide.h.m4: Specify only a type (not a
	parameter name) for unused member function parameters

2005-06-12  Paul Pogonyshev  <pogonyshev@gmx.net>

	* configure.ac:
	* scripts/cxx.m4:
	* sigc++config.h.in: Add test for whether the compiler allows
	referencing to member functions of the class/structure being
	declared from a definition of a static member variable.
	Supposedly a generic solution for GCC 3.2 compilation problems.

	* sigc++/type_traits.h: Define SIGC_WRAP_IS_BASE_CLASS_ based on
	results of the above test.
	(struct is_base_and_derived): Wrap up is_base_class_() functions
	in an internal class if SIGC_WRAP_IS_BASE_CLASS_ is defined.

2005-06-10  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/adaptors/macros/bind.h.m4:
	* sigc++/functors/macros/slot.h.m4:
	* sigc++/macros/signal.h.m4: Use CALL_SIZE instead of
	hard-coded 7s and 6s.

2.0.14:

2005-06-10  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/visit_each.h: Make the
        limit_derived_target::with_type inner class an outer class,
	to satisfy the SUN CC 5.7 compiler, though I think it is a
	compiler bug. Bug #302098 has the test case.

2.0.13:

2005-06-07  Murray Cumming <murrayc@murrayc.com>

	* tests/test_compatibility.cc: Specify the actual class when
	using test_int(), instead of the derived class, to fix the build
	on SUN Forte CC 5.5. Patch from Friedemann Kleint in
	Bug #305647

2005-06-07  Murray Cumming <murrayc@murrayc.com>

	* sigc++/macros/signal.h.m4: signal_emit::emit(): Use scope to
	ensure a certain order of destruction of the member variables, to
	avoid a leak on MSVC++. Patch by Andreas Ames in Bug #306249.

2005-06-07  Murray Cumming <murrayc@murrayc.com>

	* sigc++/macros/signal.h.m4: Added comments about commenting-out
        SIGC_TYPEDEF_REDEFINE_ALLOWED when using SUN Forte CC 5.7,
        because I can not seem to create a test for it.

2005-06-07  Murray Cumming <murrayc@murrayc.com>

	* configure.ac:
	* scripts/cxx_std.m4:
	* sigc++/macros/signal.h.m4:
	* sigc++config.h.in: Added check for
	the non-standard SUN Forte reverse_iterator<>,
	and used it. This is based on the same stuff in
	gtkmm.

2005-06-07  Murray Cumming <murrayc@murrayc.com>

	* sigc++/visit_each.h: limit_derived_target(): Just some whitespace
        changes.

2005-05-16  Neal E. Coombes  <nealc@trdlnk.com>

	* sigc++/signal_base.h:  Modified temp_slot_list to be a temporary view
	into a slot list.  Instead of emptying the original it now simply tacks
	a placeholder to the end of the original.  It then uses this as it's
	'end' iterator.  This should allow for conscious recursiveness, as well
	as inserting a slot to any position in the slot list during emittion.
	See bug #303896.

2005-06-04  Friedemann Kleint <kleint@bifab.de>

	* sigc++/macros/limit_reference.h.m4:
	visit_each() template specializations:
	Mention the bool I_derives_trackable
	template type, to fix the build on Solaris
	Forte 5.5.

2.0.12:

2005-05-06  Régis Duchesne <hpreg@vmware.com>

	* sigc++/macros/limit_reference.h.m4 (added):
	* sigc++/Makefile.am:
	New class that just stores a reference, and makes sure that if the
	reference derives from trackable, then the trackable reference will be
	used instead of the derived reference in visit_each().
	* sigc++/functors/macros/mem_fun.h.m4: Better fix for bug #169225 by
	Régis Duchesne and Christian Hammond, based on the new limit_reference
	class.
	* sigc++/adaptors/bound_argument.h (added): New class (built upon the
	new limit_reference class) that handles all 3 kinds of bound arguments:
	by value, by reference, and by constant reference. References are
	unwrapped in the bound_argument's constructor.
	* sigc++/adaptors/macros/bind.h.m4: Fix for bug #302327 by Régis
	Duchesne. Bound arguments now need to know whether they are passed by
	reference or not. So bind() now builds bind_functor instances using
	'reference_wrapper<Foo>' types, instead of 'Foo &' types. The
	bind_functor code is modified to compensate.
	* sigc++/adaptors/macros/bind_return.h.m4: Similar fix for a similar
	bug (unfiled) with bound return arguments.
	* sigc++/reference_wrapper.h:
	* sigc++/type_traits.h:
	The reference_wrapper class is only used in bound_argument.h. Put
	correct but unused code under #if 0.
	* sigc++/adaptors/lambda/base.h: This file needs reference_wrapper.h,
	but was incorrectly relying on type_traits.h to include it.
	* tests/Makefile.am:
	* tests/test_virtualbase_delete.cc (deleted):
	* tests/test_virtualbase_delete_ref_param.cc (deleted):
	* tests/test_limit_reference.cc (added):
	Replaced test_virtualbase_delete*.cc with a simpler
	test_limit_reference.cc which checks for all 3 aspects of the same bug
	in one file.
	* tests/test_bind_ref.cc: Slots must use 'Foo &' types. We were lucky
	this broken usage worked before this change. The change in
	type_traits.h made this bug obvious, by preventing the code to compile.
	* tests/test_bind_return.cc: After my change, bind() and bind_return()
	must use 'reference_wrapper<Foo>' types.
	* tests/test_custom.cc: Made this test a no-op (so it does not perturb
	'make check' on released versions of the library) and made it a
	template ready to be modified by hackers.

2005-05-01  Murray Cumming <murrayc@murrayc.com>

	* sigc++/functors/slot_base.cc:
	slot_base::slot_base(src): If the source
	slot_base has a null rep->call_, meaning that the
	slot is invalid, just return a default-constructed
	slot, to prevent the crash shown in
	tests/tests_copy_invalid_slot.cc. Bug #302515 by
	Régis Duchesne.

2005-05-01  Murray Cumming <murrayc@murrayc.com>

	* sigc++/functors/macros/mem_fun.h.m4: bound_*<>:
	Add a new is_base_and_derived<sigc::trackable>
	parameter to the template and thereby provide a
	specialization for T_Obj types that derive from
	sigc::trackable. This prevents a crash when casting
	from the derived type to sigc::trackable after the
	derived destructor has run. This cast can sometimes
	fail when using multiple inheritance, at least with
	g++. Bug #169225 by Régis Duchesne and Christian
	Hammond.
	* sigc++/type_traits.h: Add documenation for
	the internal is_base_and_derived<> template, which
	allows us to specialize other templates for certain
	template types.

2005-04-28  Murray Cumming <murrayc@murrayc.com>

	* sigc++/type_traits.h: Added comments for users of
	g++ 3.2.

2005-04-28  Murray Cumming <murrayc@murrayc.com>

	* tests/Makefile.am:
	* tests/test_virtualbase_delete.cc: Added
	simplified test case from bug #169225. We have a patch
	to make this succeed but I am not ready to commit it
	just yet.

2005-04-27  Murray Cumming <murrayc@murrayc.com>

	* tests/Makefile.am:
	* tests/test_custom.cc:
	Added a place to put extra test code, so I don't have
	to keep installing my crazy libsigc++ versions.

2005-04-27  Murray Cumming <murrayc@murrayc.com>

	* sigc++/visit_each.h: Revert back to the non-explicit
	template call, because we can not specify the
	template specialization so easily, because the
	specializations have different numbers of types.
	* tests/Makefile/am:
	* tests/test_bind_ref.cc: Add a simple test only for
	sigc::ref disconnection.

2005-04-26  Murray Cumming <murrayc@murrayc.com>

	* sigc++/visit_each.h: Use the explicit template
	specialization, needed for Tru64 and AIX compilers.
	This causes a crash in some uses of sigc::ref()
        (when using g++ 3.3.4 or 3.3.5 , but not with 3.4) but
	seems to fix a crash in some uses of multiple inheritance
	(bug #169225).
	* tests/test_bind.cc: Comment out the crashing (not with
	g++ 3.4) use of sigc::ref() with an explanatory comment.

2.0.11:

2005-03-09  Cedric Gustin <cedric.gustin@swing.be>

	* Makefile.am: Moved MSVC_Net2003 directory to SUBDIRS.
	* MSVC_Net2003/Makefile.am: Added blank.cpp to EXTRA_DIST.
	* MSVC_Net2003/libsigc++2_msvcNet2003.sln: Removed
	test_accumulated and test_lambda projects as the tests are
	disabled in the standard, configure-based build.
	* MSVC_Net2003/MSVC_Net2003/libsigc++2_msvcNet2003.vcproj:
	Generate a PDB file in the Debug target.

2005-03-05  Murray Cumming  <murrayc@murrayc.com>

	* docs/website/stable.html: Mention actual supported compilers.
	* docs/website/docs.html: Removed broken examples links. Change
	reference link to the reference overview page.

2005-02-23  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/functors/slot_base.h: Make slot_base::operator=() public, to
	fix the build with SUN Forte C++ 5.5 and Tru64.

2.0.10:

2005-02-20  Murray Cumming  <murrayc@murrayc.com>

	* tests/test_slot.cc, test_disconnect.cc: #included <new> to avoid
	an unresolved symbol error with the Tru64 compiler. Solution found by
	Tim Mooney in bug #161503.

2005-02-20  Martin Schulze  <mschulze@cvs.gnome.org>

	* sigc++/signal_base.h: Add some documentation.

2005-02-20  Martin Schulze  <mschulze@cvs.gnome.org>

	* sigc++/signal_base.cc: Reset deferred_ flag to false in
	signal_impl::sweep() (Neal E. Coombes). Partly fixes bug #167714.

2005-02-11  Martin Schulze  <mschulze@cvs.gnome.org>

	* docs/manual/Makefile.am: Set the correct group in post-html.

2005-02-11  Murray Cumming  <murrayc@murrayc.com>

	* docs/website/doc.shtml: Fix typo in url for reference docs. Found by
	James Lin.

2005-02-06  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/signal_base.h: temp_slot_list::begin(), end(): Actually
	return the iterators.

2005-02-03  Neal E. Coombes <nealc@trdlnk.com>

	* sigc++/signal_base.h: Add temp_slot_list struct to facilitate
	allowing new connections to a signal during an emittion without
	affecting that emittion.
	* sigc++/macros/signal.h.m4: Use the new struct temp_slot_list to
	prevent connections made during an emittion from being called in the
	same emittion (which has the potential of causing things like
	infinite loops).  This guarantees an emittion will be finite, as well
	as maintaining any order of emittion guarantees that may have already
	been in place.

2.0.9:

2005-02-02  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/visit_each.h: visit_each_type(): Reverted the change, so that
	we do not specify the template types ot visit_each<>(), because it
	crashes on g++ 3.3.4 (but not g++ 3.4.2). Added a comment telling users
	of AIX (and maybe IRIX MipsPro and Tru64) to use the alternative version
	if they have compilation problems.

2005-02-01  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/adapators/macros/base.h.m4: Add sigc::var<>() documentation,
	from Roger Ferrer Ibáñez in bug #149483.

2005-02-01  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/adaptors/macros/compose.h.m4: In the template specializations
	of visit_each(): As before, specify the specific other template
	specializations of visit_each that we use. Needed by AIX.
	* tests/Makefile.am: Reenabled most tests, because AIX can now
	build them.

2005-02-01  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/visit_each.h: visit_each_type(): Specify the specific
	template specialization of visit_each<>() to use. The AIX compiler,
	and possibly the Tru64 compiler, need this extra hint.

2005-02-01  Murray Cumming  <murrayc@murrayc.com>

	* bind.h.m4: Define bind_functor::operator() inline because the AIX
	compiler/linker sometimes fails to find it when it is defined
	outside of the class.

2.0.8:

2005-01-30  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/type_traits.h: is_base_and_derived: Added
	avoid_gcc3_warning_(), to avoid an incorrect warning when using
	g++ 3.3.5

2005-01-28  Liza Klerck   <liza@trdlnk.com>

	* sigc++/functors/macros/mem_fun.h.m4: Add a sigc:: namespace
	prefix to the nested use of visit_each(), to avoid ambiguity when
	using 2 versions of the libsigc++ API inside different namespace.

2005-01-27  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/adaptors/macros/adaptor_trait.h.m4: Add a sigc:: namespace
	prefix to the nested use of visit_each(), to avoid ambiguity when
	using 2 versions of the libsigc++ API inside different namespace,
	which is not very advisable anyway. Bug #165222 from
	liza at trdlnk.com.

2.0.7:

2005-01-24  Cedric Gustin <cedric.gustin@swing.be>

	* sigc++config.h.in : Moved the SIGC_USING_STD macro definition
	out of the SIGC_CONFIGURE section. We also need it for MSVC.
	* MSVC_Net2003/.cvsignore : Added .def and .aps files
	* MSVC_Net2003/Makefile.am: Rewrote rule for local copy of
	sigc++config.h (required for 'make distcheck').
	* MSVC_Net2003/libsigc++2_msvcNet2003.sln: Added test_retype and
	test_disconnect_during_emit tests.
	* MSVC_Net2003/tests/test_disconnect_during_emit/*,
	MSVC_Net2003/tests/test_retype/*: Initial commit.

2005-01-21  Murray Cumming  <murrayc@murrayc.com>

	* tests/: Disabled the test_accumulator, test_bind, and test_compose
	tests, and part of test_mem_fun because the AIX xlC compiler can not
	build them, but it can still do most things, including the examples.
	See the comments in tests/Makefile.am.

2005-01-21  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/adaptors/bind.h.m4: non-member operator()(): Specify the
	extra nil arguments in the templated class name prefix. Oddly, the
	AIX xlC compiler says that the type of the first parameter does not
	match the template if you don't do this.

2005-01-21  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/type_traits.h: is_base_and_derived struct: Move the
	is_base_class_() functions out of the inner class, because the AIX
	xlC compiler does not like that - see the comments in the code.
	* sigc++/adaptors/bind.h.m4: Add the extra nil template types to
	the template specializations, as in slot and signal.

2005-01-21  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/functors/macros/slot.h.m4, sigc++/macros/signal.h.m4:
	slot and signal template specialization for
	various numbers of template args: In the class slot line, specify
	all the remaining template types as null, instead of expecting the
	compiler to guess them in itself. This partly fixes the build on
	AIX with the xlC compiler. Bug #164685.

2005-01-19  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/type_traits: struct is_base_and_derived: Make the test inner
	struct a friend, so that it can use the big inner struct. This is
	required by the Tru64 compiler.
	* sigc++/adaptors/lambda/base.h: Put the unwrap_lambda_value()
	definitions at the top, because Tru64 (understandably) needs them to
	be declared before use.

2005-01-19  Murray Cumming  <murrayc@murrayc.com>

	* scripts/: Added cxx_std.m4, with a test copied from
	glibmm/scripts/cxx_std.m4 to check if the compiler has the std::
	namespace.
	* sigcconfig.h: #undef the new #define and add SIGC_USING_STD(),
	like GLIBMM_USING_STD, to put stuff in the std:: namespace when it
	is not there already,
	* configure.in: Used the new test.
	* tests/*: Uses SIG_USING_STD() for every std:: thing that we use.
	This is needed by the Tru64 and HP-UX compilers when using their
	defaults.

2005-01-19  Murray Cumming  <murrayc@murrayc.com>

	* configure.in: AC_INIT(): Provide the extra tarball name parameter,
	so that it does not create a libsigc--- tarball.

2005-01-19  Murray Cumming  <murrayc@murrayc.com>

	* configure.in: AC_INIT(): Use libsigc++ instead of sigc++, attempting
	to get the correct tarball name.

2005-01-18  Murray Cumming  <murrayc@murrayc.com>

	* configure.in: Used the autoconf 2.93 and AM_INIT_AUTOMAKE()
	technique to specify ustar format for the tarball, to prevent files
	with long file names from appearing at the top of the tarball.
	Based on the same fix in gtkmm 2.6.

2005-01-18  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/functors/macros/slot_h.m4: Specify the base class when
	using the rep_ member variable. This stops the HP-UX aCC compiler
	from saying that a Nonstatic member  is referenced in a nested class,
	local class or static member initializer. Bug #150719.

2005-01-18  Murray Cumming  <murrayc@murrayc.com>

	* Bug #159597 - patch from e97_far at e.kth.se to replace C-style
	casts with reinterpret_cast<> and static_cast<> to avoid warnings.

2005-01-17  Murray Cumming  <murrayc@murrayc.com>

	* docs/manual/Makefile.am: Specifying html/index.html instead of
	just the html directory as a target seems to fix distcheck problems.
	I can also now confirm that the install works on solaris, when using
	gmake, though not when using make.

2005-01-17  Murray Cumming  <murrayc@murrayc.com>

	* MSVC_Net2004/Makefile.am: Add built files to DISTCLEANFILES to fix
	the distcheck.
	* docs/reference/Makefile.am, manual/Makefile.am: Specify $srcdir in
	paths, to fix distcheck of the manual, and maybe fix install problems
	on Solaris.

2005-01-11  Murray Cumming  <murrayc@murrayc.com>

	* docs/website/stable.html: Updated the text about binary packages.
	* docs/website/docs.html: Link to the 2.0 documentation instead of the
	1.2 documentation.

2004-12-17  GregSchussman  <schussman@slac.stanford.edu>

 	* glossary.shtml: Clean up punctuation, make definitions complete
        sentences, and add clarifications for certain definitions according to
        what Murray Cumming's suggestions and answers to my questions.
 	Bug #161580.

2005-01-11  Murray Cumming  <murrayc@murrayc.com>

	* docs/: Added manual, copied from the libsigc++-1.2 cvs module,
	and updated it for the new 2.0 API.

2005-01-11  Murray Cumming  <murrayc@murrayc.com>

	* docs/: Added website, copied from the libsigc++-1.2 cvs module.
	We will use it from here from now on.

2004-12-11  Cedric Gustin <cedric.gustin@swing.be>

	* configure.ac : parse version tags at configure time (for
	sigc-2.0.rc).
	* MSVC_Net2003/sigc-2.0.rc.in : New resource file.
	* MSVC_Net2003/Makefile.am: include sigc-2.0.rc in distribution.

2004-12-08  Cedric Gustin <cedric.gustin@swing.be>

	* MSVC_Net2003/Makefile.am: get sigc++config.h from $(top_builddir)
	instead of $(top_srcdir).

2004-12-08  Cedric Gustin <cedric.gustin@swing.be>

	* MSVC_Net2003/*/*.vcproj: Renamed libsigc++ target to
	sigc-2.0d.dll (Debug) and sigc-2.0.dll (Release). Added
	$(SolutionDir) and $(SolutionDir)\.. to "Additional Include
	Directories" in tests projects.
	* sigc++config.h.in: Rewrote dllexport/dllimport macros for
	MSVC, for better consistency with glibmm/gtkmm.
	* MSVC_Net2003/Makefile.am: copy sigc++config.h from $(top_srcdir)
	at build time.

2004-11-27  Murray Cumming  <murrayc@murrayc.com>

	* configure.in: Revert the AC_PROG_LIBTOOL change, so that this builds
	with actually released libtool versions, and in jhbuild, so that it
	gets testing.

2004-11-06  Martin Schulze  <mschulze@cvs.gnome.org>

	* sigc++/adaptors/macros/exception_catch.h.m4: Make catcher_ member
	public so that it can be accessed by visit_each() (bug reported on
	ml by Philip Langdale <plangdale@vmware.com>).

2004-10-24  Martin Schulze  <mschulze@cvs.gnome.org>

	* MSVC_Net2003/*/*.vcproj: Link with the "multithreaded DLL" runtime
	libraries and enable RTTI for the MSVC build
	(patch from Timothy M. Shead <tshead@k-3d.com>).
	* MSVC_Net2003/*/.cvsignore: Hide generated build files from cvs
	(patch from Timothy M. Shead <tshead@k-3d.com>).

2.0.6:

2004-10-12  Martin Schulze  <mschulze@cvs.gnome.org>

	* MSVC_Net2003/*/*.vcproj, MSVC_Net2003/blank.cpp: Fix project files
	to compile out-of-the-box and add dummy file so that .cc files get
	recognized as c++ code files (patch from Timothy M. Shead).

2004-10-10  Martin Schulze <mschulze@cvs.gnome.org>

	* sigc++/signal_base.{h,cc}, sigc++/functors/slot_base.{h,cc},
	sigc++/functors/macros/slot.h.m4: If SIGC_NEW_DELETE_IN_LIBRARY_ONLY
	is defined, implement signal_base::operator new/delete and
	slot_rep::operator new/delete (suggested by Timothy M. Shead).
	Remove old work-around from 2004-10-02 since it didn't work.

2004-10-07  Martin Schulze <mschulze@cvs.gnome.org>

	* configure.ac: Update for libtool 1.5a (with support for Intel C++).
	* MSVC_Net2003/sigc++config.h: Remove bogus '#define'
	(reported by Timothy M. Shead <tshead@k-3d.com>).

2004-10-02  Martin Schulze <mschulze@cvs.gnome.org>

	* configure.ac: Bump version number to 2.0.6.
	* NEWS: Add ChangeLog summary for version 2.0.6.

2004-10-02  Martin Schulze <mschulze@cvs.gnome.org>

	* sigc++/functors/slot_base.{h,cc}, sigc++/functors/macros/slot.h.m4:
	Rename (typed_)slot_rep::detach to (typed_)slot_rep::destroy.
	Call the dtor of the functor stored in typed_slot_rep from destroy().
	A cleaner solution would be to add an additional "virtual" function
	that calls 'delete' or a real virtual dtor. However, this would be
	less efficient and might break the ABI. (Fixes #152323.)

2004-10-02  Martin Schulze <mschulze@cvs.gnome.org>

	* sigc++config.h.in, MSVC_Net2003/sigc++config.h,
	sigc++/signal_base.cc, sigc++/functors/slot_base.{h,cc},
	sigc++/functors/macros/slot.h.m4: Define and use new macro
	SIGC_NEW_DELETE_IN_LIBRARY_ONLY to ABI-compatibly move
	all calls to new and delete into non-inline library code.

2004-09-26  Martin Schulze <mschulze@cvs.gnome.org>

	* sigc++/adaptors/lambda/macros/group.h.m4: Add a missing
	template keyword in the definition of deduce_result_type::type
	(hopefully fixes #152327).

2004-09-26  Martin Schulze <mschulze@cvs.gnome.org>

	* sigc++/macros/object_slot.h.m4: Use correct bound_mem_functor
	variants for const (volatile) methods (fixes #148744).

2004-09-01  Martin Schulze <mschulze@cvs.gnome.org>

	* docs/index.html: Correct link to lambda module.

2004-09-01  Martin Schulze <mschulze@cvs.gnome.org>

	* README: Update compatibility section.

2.0.5:

2004-09-01  Martin Schulze <mschulze@cvs.gnome.org>

	* MSVC_Net2003/Makefile.am: Add sigc++config.h to EXTRA_DIST.
	* configure.ac: Bump version number to 2.0.5.
	* NEWS: Add ChangeLog summary for version 2.0.5.

2.0.4:

2004-08-21  Martin Schulze <mschulze@cvs.gnome.org>

	* tests/test_lambda.cc: Use sigc::var("\n") instead of sigc::ref("\n").
	Comment out the affected lines, nevertheless.
	Sun FORTE and Compaq C++ can handle neither sigc::ref("\n") nor
	sigc::var("\n"). I see more chances fixing sigc::var("\n").
	* sigc++/adaptors/lambda/macros/base.h.m4: Add a comment about a
	possible work around for sigc::var("\n") compiler problems.
	* tests/test_compatibility.cc: Remove a 'const' keyword that prevents
	the test case from compiling with the Sun FORTE.
	* tests/test_trackable.cc: Remove a 'virtual' keyword and an unused
	variable to avoid compiler warnings.
	* NEWS: Add ChangeLog summary for version 2.0.4.

2004-08-03  Martin Schulze <mschulze@cvs.gnome.org>

	* scripts/cxx.m4, sigc++config.h.in, configure.ac,
	sigc++/adaptors/lambda/macros/operator.h.m4, tests/test_lambda.cc:
	Rollback change from 2004-07-15: configure check
	SIGC_OPERATOR_OVERLOAD_AMBIGUITY is not needed - the overload
	ambiguity doesn't occur if the lambda operators take all arguments
	as const reference.
	* configure.ac: Bump version number to 2.0.4.

2004-08-03  James Lin <slimjimmy@mail.com>

	* Added SIGC_API qualifier to all externally-visible non-template
	classes/structs.
	* Added #include <sigc++config.h> to the files that use SIGC_API.
	* Added empty SIGC_API definition to sigc++config.h.in for non-MSVC
	compilers.  I'm not sure if this is the right place to put this
	(probably not).
	* Added MSVC-specific sigc++config.h to the MSVC project directory.
	(The comment in it probably should be edited.)
	* Changed MSVC project settings to output a multi-threaded DLL, set
	the include paths to work (hopefully) out-of-the-box.  Disabled
	precompiled headers, since they just complicate things and
	shouldn't be necessary for such a relatively project.

2004-08-01  Martin Schulze <mschulze@cvs.gnome.org>

	* sigc++/type_traits.h: Remove type_trait<>::instance()
	(was unimplemented and unused; caused problems with the MSVC).

2004-07-23  Martin Schulze <mschulze@cvs.gnome.org>

	* Makefile.am: Fix typo concerning distribution of libsigc++-2.0.spec.
	* AUTHORS: Mention our contributors for platforms Sun FORTE and Intel C++.

2004-07-15  Martin Schulze <mschulze@cvs.gnome.org>

	* *.h.m4: Don't call operator()() in sun_forte_workaround(); rather copy
	operator()(). Calling operator()() makes a copy of the arguments causing
	wrong results if an argument type is a reference. Hopefully fixes #147311.

2004-07-15  Martin Schulze <mschulze@cvs.gnome.org>

	* tests/test_lambda.cc: Break "std::cout << [expr] << a << std::endl;"
	into "std::cout << [expr]; std::cout << a << std::endl;".
	I hope this fixes #147313 where the right values for "[expr]" but wrong
	values for "a" were written to std::cout for some compiler with optimizations
	turned off.

2004-07-15  Martin Schulze <mschulze@cvs.gnome.org>

	* sigc++/adaptors/lambda/macros/operator.h.m4: Correct return type deduction
	of lambda expressions in lambda_operator*::operator()(). Might be related to
	bug #147313.
	* sigc++/adaptors/lambda/macros/group.h.m4: Use m4 macro _P_().

2004-07-15  Martin Schulze <mschulze@cvs.gnome.org>

	* scripts/cxx.m4, sigc++config.h.in, configure.ac,
	sigc++/adaptors/lambda/macros/operator.h.m4, tests/test_lambda.cc:
	Add configure check SIGC_OPERATOR_OVERLOAD_AMBIGUITY for a SUN FORTE
	compiler problem (bug #147391). Use it to decide whether the lambda
	action operators may be overloaded (not doing so restricts the API slightly).
	* sigc++/adaptors/lambda/macros/operator.h.m4: Add some doxygen comments
	and remove attic code.
	* sigc++/adaptors/lambda/macros/base.h.m4:
	Add templates unwrap_lambda_type and unwrap_lambda_value() to support
	the non-overloaded lambda action operators. Also add some doxygen comments
	and remove attic code.
	* sigc++/adaptors/lambda/macros/group.h.m4: Fix a bug that resulted in
	gargabe values being passed on to the functor contained in the group adaptor
	(partly fixes #147313).

2004-07-11  Martin Schulze <mschulze@cvs.gnome.org>

	* scripts/cxx.m4, sigc++config.h.in, configure.ac, *.h.m4:
	Split SIGC_CXX_TEMPLATE_SPECIALIZATION_OPERATOR_OVERLOAD
	into SIGC_CXX_GCC_TEMPLATE_SPECIALIZATION_OPERATOR_OVERLOAD
	and SIGC_CXX_MSVC_TEMPLATE_SPECIALIZATION_OPERATOR_OVERLOAD.
	Remove LIBSIGC_TEMPLATE_PREFIX. Add template keyword to
	SIGC_WORKAROUND_OPERATOR_PARENTHESES depending on the configure checks.
	Should fix the compiler problems with MSVC.

2004-07-11  Martin Schulze <mschulze@cvs.gnome.org>

	* examples/hello_world.cc: Use sigc::ptr_fun instead of std::ptr_fun.
	(fixes bug #144846)

2004-07-11  Eric Bourque <ericb@computer.org>

	* libsigc++-2.0.spec.in: new file
	* configure.ac : patched generate spec file
	* .cvsignore: ignore generated file (Martin Schulze)
	* Makefile.am: distribute spec file (Martin Schulze)

2004-07-11  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/connection.cc: Added some comments.
	* sigc++/trackable.cc: operator=(): Check for self-asignment, though I
	do not know of any actual bug that this fixes. Added some comments.
	* sigc++/trackable.h Added some doxygen documentation.

2004-07-09  Murray Cumming  <murrayc@murrayc.com>

	* tests/: Added test_disconnect_during_emit.cc, to prove that this
	works.

2004-07-08  Murray Cumming  <murrayc@murrayc.com>

	* tests/test_retype_return.cc: foo::operator(int): return a
	value. The SUN Forte 5.5 compiler complains about this, as it should.

2004-07-08  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/macros/signal.h.m4: class signal*: Rename the slot_list
	typedef to slot_list_type, because there is already a template class
	called slot_type. SUN Forte 5.5 seems to complain about this and I am
	not surprised. The old typdef is still there for backwards
	compatibility, except when building with SUN Forte.

2004-07-07  Murray Cumming  <murrayc@murrayc.com>

	* scripts/cxx.m4: SIGC_CXX_TEMPLATE_SPECIALIZATION_OPERATOR_OVERLOAD():
	Don't define the SIGC_TEMPLATE_SPECIALIZATOIN_OPERATOR_OVERLOAD C
	macro at all if the test fails. This might fix the build on SUN Forte.
	* sigc++/functors/macros/mem_fun.h.m4: Default constructor: Initialize
	the func_ptr_ member variable. I have no evidence that this solves any
	problems, but it worried me.
	* sigc++/functors/slot_base.h: operator bool(): Correct documentation,
	to use @code instead of <code>
	* sigc++/macros/signal.h.m4: Remove the documentation for the
	parameters named first and last, because they do not exist.

2004-05-31  Martin Schulze  <mschulze@cvs.gnome.org>

	* autogen.sh: Add '--force'-flag to the 'libtoolize'-command (bug #143425).

2.0.3:

2004-05-30  Martin Schulze  <mschulze@cvs.gnome.org>

	* configure.ac: Bump version number to 2.0.3.
	* NEWS: Add ChangeLog summary for version 2.0.3.
	* sigc++/macros/signal.h.m4: Fix segfault on emission of unconnected signal.
	* tests/test_signal.cc, tests/test_accumulated.cc: Emit unconnected signal.
	* sigc++/macros/object_slot.h.m4: Suppress compiler warning at
	dynamic_cast<>-test (tested by Christof Petig/Timothy M. Shead).

2.0.2:

2004-05-22  Martin Schulze  <mschulze@cvs.gnome.org>

	* configure.ac: Bump version number to 2.0.2.
	* NEWS: Add ChangeLog summary for version 2.0.2.

2004-05-20  Martin Schulze  <mschulze@cvs.gnome.org>

	* sigc++/macros/signal.h.m4: If a custom accumulator is specified
	invoke it on signal emission even if the signal's slot list is empty.
	(This used to be the case in libsigc++-1.2 as pointed out by Timothy.)

2004-05-20  Martin Schulze  <mschulze@cvs.gnome.org>

	* sigc++/macros/object_slot.h.m4: Suppress compiler warning at
	dynamic_cast<>-test (suggested by Timothy M. Shead).

2004-05-01  Martin Schulze  <mschulze@cvs.gnome.org>

	* README: Updated for libsigc++-2.0.

2.0.1:

2004-04-27  Martin Schulze  <mschulze@cvs.gnome.org>

	* configure.ac: Bump version number to 2.0.1.
	* NEWS: Add ChangeLog summary for version 2.0.1.
	* sigc++/adaptors/lambda/macros/base.h.m4: Fixed documentation.
	* sigc++/adaptors/macros/bind.h.m4: Hide work-arounds from doxygen.
	* scripts/cxx.m4, sigc++config.h.in, configure.ac,
	sigc++/adaptors/macros/bind.h.m4: Removed configure	check. It
	showed that the Apple gcc can also compile the sophisticated version
	of the work-around.

2004-04-26  Martin Schulze  <mschulze@cvs.gnome.org>

	* sigc++/macros/object_slot.h.m4: Modified test for SigC::Object
	inheritance so that it also works if SigC::Object is virtual base.
	(Fixes bug 141094 reported by Jonathan Brandmeyer)

2004-04-26  Martin Schulze  <mschulze@cvs.gnome.org>

	* scripts/cxx.m4: Updated the configure check. It would probably
	have succeeded on the Apple.

2004-04-26  Martin Schulze  <mschulze@cvs.gnome.org>

	* sigc++/adaptors/macros/bind.h.m4: Add work-arounds for
	bind<-1>::deduce_result_type compilation error on Apple gcc 3.3.
	* scripts/cxx.m4, sigc++config.h.in, configure.ac: Add configure
	check for the compilation error above.
	* sigc++/adaptors/lambda/macros/operator.h.m4: Replace _A with
	_Aa. _A is a reserved keyword on Apple gcc 3.3 (Spundun Bhatt).
	(fixes bug #10444 reported by Spundun Bhatt)

2004-04-19  Martin Schulze  <mschulze@cvs.gnome.org>

  * sigc++/signal_base.cc: Fixed serious bug in signal_base::impl():
  Only reference a newly created object (initial reference).
  (This fixes bug #140269 reported by Andris.)

2004-04-19  Murray Cumming  <murrayc@murrayc.com>

	* scripts/cxx.m4: Updated the operator() template check, because it
	failed with gcc 3.4 (from cvs). Apparently the template keyword can
	only be used from another template.

2.0.0:

2004-04-06  Martin Schulze  <mschulze@cvs.gnome.org>

	* configure.ac: Bump version number to 2.0.0.
	* NEWS: Add ChangeLog summary for version 2.0.0.
	* TODO, AUTHORS: Bring up to date.
	* sigc++-2.0.pc.in, Makefile.am: 1.9 -> 2.0
	* Added more documentation.

2004-04-10  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/connection.[h|cc]: Implement blocked() to avoid undefined
	symbol linker error.

2004-04-08  Murray Cumming  <murrayc@murrayc.com>

	* dist the scripts directory.

1.9.16:

2004-04-06  Martin Schulze  <teebaum@cvs.gnome.org>

	* configure.ac: Bump version number to 1.9.16.
	* NEWS: Add ChangeLog summary for version 1.9.16.

2004-04-02  Murray Cumming  <murrayc@murrayc.com>

	* sigc++/connection.cc: Make block() and unblock() always return a
	value, to fix compiler warnings. Patch from bug #138620 by
	Alexander Nedotsukov.

2004-04-02  Murray Cumming  <murrayc@murrayc.com>

	* Fix the compile of examples/member_method.cc. Bug #131701 from
	Kirill Smelkov. I also made the examples build as part of the regular
	build.

2004-04-02  Murray Cumming  <murrayc@murrayc.com>

	* sigc++config.h.m4: Remove every undef apart from the one we need, to
	avoid clashes, because we #include this in a public header.

2004-03-25  Murray Cumming  <murrayc@murrayc.com>

	* scripts/cxx.m4, configure.in, sigc++config.h.in: Rename the
	template_keyword check to template_specialization, because the problem
	is with or without the keyword.
	* sigc++/adaptors/macros/adaptor_trait.h.m4: Define
	SIGC_WORKAROUND_OPERATOR_PARENTHESES, which calls either operator() or
	sun_forte_workaround() depending on the result of the compiler test.
	* many .m4 files: Add sun_forte_workaround methods that call the
	operator() methods. Put them in #ifdefs so that only SUN Forte C++
	sees them.

2004-03-22  Murray Cumming  <murrayc@murrayc.com>

	* Makefile.am, sigc++/Makfile.am: Fix the sigc++config.h.in disting,
	to fix make distcheck.

2004-03-21  Murray Cumming  <murrayc@murrayc.com>

	* Rename config.h.in to sigc++config.h.in so that gtkmm does not
	include some other config.h at strange times - fixes a problem in
	the gtkmm demos. This should really be in the sigc++ directory, but
	that seems to add that as an include path, which causes the STL
	headers to include sigc++/signal.h instead of some STL signal.h header.

2004-03-20  Murray Cumming  <murrayc@murrayc.com>

	* Makefile.am: Install the config.h platform-specific header.
	* sigc++-2.0.pc.in: Report the include path for config.h

2004-03-20  Murray Cumming  <murrayc@murrayc.com>

	* Added config.h.in, using autoheader, from which config.h will be
	generated, so we can detect compiler features.
	* configure.ac: Added AC_CONFIG_HEADER(config.h) to generate config.h
	from config.h.in.
	* scripts/cxx.m4: Added this directory and file, with a
	SIGC_CXX_TEMPLATE_KEYWORD_OPERATOR_OVERLOAD macro that defines
	the SIGC_TEMPLATE_KEYWORD_OPERATOR_OVERLOAD C macro.
	* autogen.sh: Added -I scripts to the aclocal call, so that it finds
	the m4 macro for configure.ac.
	* sigc++/adapators/macros/adaptor_trait.h.m4: Include config.h and
	use SIGC_TEMPLATE_KEYOWRD_OPERATOR_OVERLOAD.

2004-03-18  Martin Schulze  <mschulze@cvs.gnome.org>

  * tests/test_mem_fun.cc, tests/test_ptr_fun.cc: Don't test
  making functors from overloaded methods with partial template
  specialization. Not portable among different compilers (SUN FORTE).
  * adaptors/macros/apdaptor_trait.h.m4: Only gcc seems to use the
  notation A.template operator()<...>(...) => adapt preprocessor check
  for #define LIBSIGC_TEMPLATE_PREFIX. TODO: replace with configure check.

2004-03-13  Murray Cumming  <murrayc@murrayc.com>

	* g++ 3.4 (pre-release) build fixes:
	* sigc++/macros/signal.h.m4: slot_iterator_buf::operator*():
	Use blocked() and empty() instead of non-existant blocked_and_empty().
	* sigc++/functors/macros/mem_fun.h.m4: memfun_functor*::operator()():
	Use this->func_ptr_ instead of just func_ptr_.
	* sigc++/adaptors/macros/deduce_result_type.h.m4: Use
	T_functor::template deduce_result_type<> instead of just
	T_functor::deduce_result_type<>.
	* sigc++/adaptors/lambda/macros/base.h.m4, operator.h.m4, group.h.m4::
	Use template keyword again. operator[](): Use this->value_ instead of
	just value_.
	* sigc++/adaptors/lambda/macros/bind/m4: Use template keyword, and
	this-> again.
	* sigc++/adaptors/macros/compose.h.m4, hide.h.m4, bind_return.h.m4,
	exception_catch.h.m4:
	rettype.h.m4, rettype_return.h.m4: Use template keyword,and this-> again

  * sigc++/functors/macros/slot.h.m4: Make the unnumbered slot templates'
  copy ctors use the copy ctors of the base class. Fixes bug #24698.
  * tests/test_slot.cc: Test copy ctor (Bryan Forbes).

2004-02-27  Martin Schulze  <teebaum@cvs.gnome.org>

  * tests/type_functor_trait.cc: Bring it up-to-date (use sigc::ref).
  Make it work with the SUN Forte.

2004-02-24  Martin Schulze  <teebaum@cvs.gnome.org>

  * sigc++/type_traits.h: Make is_base_and_derived<> work with the SUN Forte.

  * sigc++/type_traits.h: Make is_base_and_derived<> platform independant.
  * sigc++/adaptors/lambda/macros/base.h.m4: Make lambda_core<> ctors
  explicit. Remove an unused ctor from lambda_core<T_type, true>.

2004-02-14  Martin Schulze  <teebaum@cvs.gnome.org>

  * sigc++/functors/slot_base.h, sigc++/functors/macros/slot.h.m4:
  Move some documentation to slot_base.h.
  * sigc++/signal_base.h, sigc++/macros/signal.h.m4:
  Move some documentation to signal_base.h.

  API addition:
  * sigc++/functors/macros/slot.h.m4: Add numbered slot# templates.
  Make unnumbered slot templates inherit from slot#.

  API change:
  * sigc++/functors/macros/mem_fun.h.m4: Allow for methods of the object's
  base types to be passed into sigc::mem_fun(). (Used to be the case in
  libsigc++-1.2).

2004-02-13  Murray Cumming  <murrayc@usa.net>

	* sigc++/functors/slot_base.[h|cc], sigc++/trackable.[h|cc]: Create
	and use a typedef for the destroy_notify callback functions, to avoid
	confusion function pointer declaration syntax in the API.

2004-02-13  Murray Cumming  <murrayc@murrayc.com>

	* Moved implementation to .cc files:
	* sigc++/functors/: Added slot_base.[h|cc] which contains non-template
	code that was previsouly in the generated functors/slot.h and
	non-generated slot.cc files. All non-inline implementation is now in
	the .cc file.
	* sigc++/functors/macros/slot.m4: Removed the code that has been moved
	to slot_base.[h|cc].
	* sigc++/: Added signal_base.[h|cc] which contains non-template code
	that was previously in the generated signal.h and non-generated
	signal.cc file. All non-inline implementation is now in the .cc file.
	* sigc++/macros/signal.m4: Removed the code that ahs been moved to
	signal.cc
	* sigc++/connector.[h|cc]: method implementation moved to the .cc file.

	* configure.ac: Bump version number to 1.9.14.
	* NEWS: Add ChangeLog summary for version 1.9.14.

2004-02-09  Murray Cumming  <murrayc@usa.net>

	* sigc++/functors/macros/slot.h.m4: slot_base: Added operator bool(), needed to
	check for a slot that is created with the default constructor. This was
	present in libsigc++ 1.2 also.

2004-02-06  Murray Cumming  <murrayc@usa.net>

	* Makefile.am: Build the docs directory, by adding it to SUBDIRS.
	* docs/Doxyfile.in: Updated to be more glibmm-like.
	* Added some @deprecated doxygen bits.
	* sigc++/macros/signal.h.m4: Call base constructor from signal_base
	constructor - this is an error-as-warning when building gtkmm.

	documentation. Make hide_functor ctor explicit.

2003-11-11  Martin Schulze  <teebaum@cvs.gnome.org>

	* sigc++/adaptors/macros/[bind,hide].h.m4: Change to zero-based
	argument index in numbered bind() and hide() overload
	(Agreement on the mailing list).
	Support binding up to CALL_SIZE arguments with one bind adaptor.
	(Requested by joey yandle and others).
	Only support binding of multiple arguments in unnumberd overloads
	to keep the API simple (Requested by Murray Cumming).
	* tests/test_[bind,hide,functor_trait].cc, sigc++/bind.h:
	Reflect API changes in compatibility module and test cases.

	* sigc++/adaptors/macros/[bind,hide].h.m4: Add unnumbered
	bind() and hide() overloads to make specifying the argument
	position optional (Proposed by Jeff Franks).
	* tests/test_[bind,hide].cc: Test unnumbered bind() and hide().
	* sigc++/adaptors/macros/adaptor_trait.h.m4:
	Change "#ifdef MSVC" to "#ifdef _MSC_VER" (Roel Vanhout).

2003-11-03  Martin Schulze  <teebaum@cvs.gnome.org>

	* sigc++/macros/signal.h.m4: Document accumulators.
	Move slot_iterator_buf into namespace internal. Since
	accumulators have the iterator type as a template argument
	there is no need to expose this very internal type.
	* sigc++/functors/macros/*.m4: Regroup documentation.
	Documentation of the core parts of the library should be
	complete by now.

2003-11-02  Martin Schulze  <teebaum@cvs.gnome.org>

	* Improve documentation of the core parts of the library.

	- Use a shorter notation for ..._mem_function variants.
	- Change order of mem_funcotr<>'s template arguments to
	match std::mem_fun_t and to be more consistent with adaptors.
	- Use ::sigc::slot's implicit ctor in compatibility module.
	* sigc++/adaptors/lambda/operator.h.m4: Change some
	lambda action names to match action names in std.

	API addition:
	* sigc++/adaptors/retype.h.m4: New file adding

	* sigc++/retype.h.m4: Use LIBSIGC_TEMPLATE_PREFIX
	in explicit function template instantiations.
	* sigc++/type_traits.h: Add template specialization
	for arrays (T_type[N]) to disable non-working member
	type_trait<T_type[N]>::instance().
	* sigc++/visit_each.h: Remove more disturbing
	limit_derived_target<>::operator() overloads.
	(Should have noticed earlier that they are unnecessary.)
	* sigc++/adaptors/deduce_result_type.h.m4,
	sigc++/adaptors/lambda/operator.h.m4,
	sigc++/functors/functor_trait.h.m4,
	tests/test_[bind,compose,exception_catch,hide,lambda].cc:
	Completely removed support for typeof(). We don't need
	it any more and it is completely non-standard!

2003-10-30  Cedric Gustin <cedric.gustin@swing.be>

 	* configure.ac: Added test of win32 platform. Commented
 	out AM_DISABLE_SHARED (DLLs are shared libraries).
 	* sigc++/Makefile.am: added a few LDFLAGS for win32
 	DLLs.

2003-10-30  Martin Schulze  <teebaum@cvs.gnome.org>

	Use LIBSIGC_TEMPLATE_PREFIX in explicit function
	template instantiations.
	* sigc++/tests/test_*.cc:
	- Include <string> where std::string is used.
	- Use double instead of float.

2003-10-27  Martin Schulze  <teebaum@cvs.gnome.org>

	* sigc++/retype.h.m4: Cleanup.

2003-10-26  Martin Schulze  <teebaum@cvs.gnome.org>

	Fixes:
	* sigc++/functors/slot.{cc,h.m4}:
	- Fix notification process: don't defer detaching of a
	slot from all referred trackables during signal emission!
	- Size optimization: replace virtual functions from
	struct typed_slot_rep with function pointers in slot_rep
	(reduces size of a typical typed_slot_rep instantiation
	by 30% !!!).
	* tests/test_slot.cc: Test sigc::slot more thoroughly.
	* sigc++/functors/mem_fun.h.m4: Fix visit_each().
	* sigc++/adaptos/bind_return.h.m4: Add support for
	sigc::ref().

	lambda operator and lambda group creator functions.
	- Add missing visit_each() overload for lambda<> template.
	* tests/test_lambda.cc: Test auto-disconnection.
	TODO: Fix a strange bug that leads to "Bus error"
	during auto-disconnection.

	like they are used in glibmm/gtkmm.
	* sigc++/functors/slot.h.m4: Make sigc::slot::call_type public.
	(Fixes compile problems reported by Jeff Franks.)
	* sig++/type_traits.h: Don't use long long in
	sigc::is_base_and_derived.
	(Fixes compile problems reported by Jeff Franks.)

	Correct order of typedefs. (Repoted by Jeff Franks.)
	* configure.ac: Bump version number to 1.9.9.
	* NEWS: Add ChangeLog summary for version 1.9.9.

1.9.8:

	* NEWS: Add ChangeLog summary for version 1.9.8.

2003-10-19  Martin Schulze  <teebaum@cvs.gnome.org>

	* NEWS: Add announces of versions 1.9.6 and 1.9.7.
	* sigc++/compatibility.h.m4: New file. Defines namespace SigC.
	namespace SigC should be API compatible to libsigc++-1.2.
	* sigc++/Makefile.am: Build compatibility.h.
	* tests/test_compatibility.cc, tests/Makefile.am:
	Add test case for compatibility module.
	* docs/index.html: Change group names.
	* sigc++/sigc++.h: Include connection.h.
	* sigc++/connection.{cc,h}:
	- Rename dependency to destroy_notify_callback.
	- Change parameter name in set_slot() from d to data.
	- Fix operator=(): Add "return *this;"
	- Get rid of namespace functor.
	- Corrections in documentation.
	* sigc++/signal.{cc,h.m4}:
	- Add reference counter to signal_impl. Replaces "bool destroy_".
	- Move signal_base, slot_iterator[_buf], slot_list out of
	namespace internal. They are part of the public API.
	- Add convenience function signal#::make_slot().
	- Get rid of namespace functor.
	- Corrections in documentation.

	- Get rid of one-letter-parameter-names.
	- Get rid of namespace functor.
	- Corrections in documentation.
	* tests/*.cc: Get rid of "using namespace ...".

2003-09-10  Martin Schulze  <teebaum@cvs.gnome.org>

	* sigc++/adaptors/lambda/{base,operators}.h.m4:
	Add subscript ([]) and assign (=) operator. I think there are now
	enough operators available to make any future power user happy.
	The only one missing is the comma operator and if we added it
	the logical consequence would be to also add if(), switch(), do(),
	etc. lambda expressions which are really out of place in libsigc++.
	* sigc++/type_traits.h: Fix is_base_and_derived<> for const types.
	* tests/test_lambda.cc: Test new operators.

1.9.7:

2003-09-05  Martin Schulze  <teebaum@cvs.gnome.org>

	* configure.ac: Bump version number to 1.9.7.

2003-09-03  Martin Schulze  <teebaum@cvs.gnome.org>

	* sigc++/adaptors/lambda/operator.h.m4:
	- Restructure so that the size of the generated source file stays
	reasonable for 34 operators: There are only two lambda templates
	lambda_operator and lambda_operator_unary. The action is an additional
	template parameter. A small template lambda_action[_unary] is specialized
	for all actions.
	- Add most operators that boost::lambda supports. Missing operators are
	"=", "[]", "," and support for pointer arithmetic. I don't know if it's
	worth adding these. In libsigc++, the purpose of lambda operators is to
	provide some extra functionality for the group adaptor.
	* tests/test_lambda.cc:
	Test pre-increment, address and dereference operator.

2003-08-31  Martin Schulze  <teebaum@cvs.gnome.org>

	* sigc++/reference_wrapper.h, sigc++/type_traits.h, sigc++/Makefile.am:
	New file reference_wrapper.h provides ref() to specify that adaptors/lambdas
	should take a reference to the object passed into ref() instead of a copy.
	* tests/test_lambda.cc:
	- Test group() with mem_fun().
	- Use ref() where lambdas should store references to objects.
	- Test var() and constant().
	* sigc++/adaptors/lambda/base.h.m4:
	- Support ref() in return type deduction.
	- Add var() and constant() which create lambdas for usage with lambda operators.
	* sigc++/adaptors/lambda/operator.h.m4:
	- Fix return type deduction.
	- Remove operator{+,-,*,...} overloads added on 2003-08-29. ref() is way cleaner.
	* sigc++/adaptors/lambda/group.h.m4,
	sigc++/adaptors/bind.h.m4, sigc++/adaptors/compose.h.m4,
	sigc++/adaptors/exception_catch.h.m4, sigc++/adaptors/hide.h.m4:
	Fix return type deduction.

2003-08-29  Martin Schulze  <teebaum@cvs.gnome.org>

	* tests/test_lambda.cc: Add more tests.
	* sigc++/adaptors/lambda/select.h.m4, sigc++/adaptors/lambda/lambda.cc.m4:
	Make _1, _2, ... constant.
	* sigc++/adaptors/lambda/operator.h.m4:
	Add operator{+,-,*,...} overloads to distinguish between const and non-const objects.
	Store references to non-const objects rather than copies.
	This allows expressions like e.g. std::cout << _1.
	* sigc++/adaptors/lambda/base.h.m4, sigc++/adaptors/lambda/group.h.m4:
	Remove void specializations. Functors returning void are tested and work fine.

2003-08-27  Martin Schulze  <teebaum@cvs.gnome.org>

	* tests/test_callof.cc, tests/test_deduce_result_type.cc:
	Rename, correct and improve this test case.
	* tests/Makefile.am: Build and run test_deduce_result_type
	instead of test_callof.

2003-08-27  Martin Schulze  <teebaum@cvs.gnome.org>

	* Update TODO.

2003-08-27  Martin Schulze  <teebaum@cvs.gnome.org>

	* sigc++/adaptors/hide.h.m4: Remove usage of callof_ignore_arg<>.
	* sigc++/callof.h.m4, sigc++/adaptors/deduce_result_type.h.m4,
	sigc++/functors/functor_trait.h.m4:
	Remove the first and move deduce_result_type templates from
	functor_trait.h.m4 into new file deduce_result_type.h.m4.
	* sigc++/Makefile.am, sigc++/sigc++.h, sigc++/adaptors/adaptor_trait.h.m4:
	Build and include sigc++/adaptors/deduce_result_type.h instead of callof.h.
	* sigc++/functors/slot.h.m4: Document struct nil.

2003-08-24  Martin Schulze  <teebaum@cvs.gnome.org>

	* sigc++/functors/functor_trait.h.m4: Simplify usage of convenience
	macro SIGC_FUNCTORS_HAVE_RESULT_TYPE:
	namespace sigc{ namespace functor{ SIGC_FUNCTORS_HAVE_RESULT_TYPE }}

2003-08-24  Martin Schulze  <teebaum@cvs.gnome.org>

	* sigc++/functors/functor_trait.h,m4, sigc++/adaptors[/lambda]/*.h.m4:
	Merge adaptor return type deduction and typeof() into
	sigc::functor::deduce_result_type. Use it for all adaptors.
	* tests/test_compose.cc: Only test multi-type get-functor if
	typeof() if supported.

2003-08-24  Martin Schulze  <teebaum@cvs.gnome.org>

	* sigc++/adaptors[/lambda]/*.h.m4:
	- Remove unnecessary void specializations. In fact, only the one
	for sigc::functor::exception_catch<> is needed and I don't really
	understand why. For the lambda stuff the void specializatoins are
	just commented out at the moment.
	- Make typeof() optional. Surprisingly, I got the lambda stuff working
	without typeof()! The test suite doesn't catch all cases yet, so maybe
	some thing are still not working.
	TODO: Implement configure check.
	* tests/test_bind.cc, tests/test_compose.cc tests/test_exception_catch.cc,
	tests/test_hide.cc, tests/test_lambda.cc:
	Only test multiple functor return types if typeof() is supported.

2003-08-06  Martin Schulze  <teebaum@cvs.gnome.org>

	* sigc++/trackable.{cc,h}: Add function trackable::clear().

2003-06-24  Andreas Rottmann  <rottmann@users.sourceforge.net>

	* TODO: Minor tweaks.

2003-06-23  Andreas Rottmann  <rottmann@users.sourceforge.net>

	* docs/reference/Doxyfile.in: Use these variables.
	* docs/reference/Makefile.am (html/index.html): Provide doxygen
	with SRCDIR and TOP_SRCDIR environment variables.

	* sigc++/functors/slot.h.m4: Make slot::call_type typedef public;
	this fixes a g++ 3.3 error in signal.h.

	* sigc++/signal.h.m4: Make the signal::accumulated class public;
	this fixes a g++ 3.3 error in test_accumulated.cc.

2003-06-15  Martin Schulze  <teebaum@cvs.gnome.org>

	* sigc++/functor/slot.h.m4: Correct typing error in docs.
	* sigc++/functor/ptr_fun.h.m4: Document the whole thing.

2003-05-31  Murray Cumming  <murrayc@usa.net>

	* Reference documentation: Rearranged the groups to make it all
	a bit more like the libsigc++ 1.2 reference documentation.
	Corrected some spelling and grammar too.
	This needs a lot of work. The text is very hard to read and it's
	generally not appropriate for a user of the code who doesn't
	care about the internals. But it's not impossible - our examples
	should show us what we need to say in the documentation.
	We probably need some more groups for the extra stuff, like we do
	in libsigc++ 1.2.

2003-05-29  Martin Schulze  <teebaum@cvs.gnome.org>

	* sigc++/signal.h.m4: Fix documentation.
	* sigc++/connection.h, sigc++/functor/slot.h.m4:
	Document the whole thing.

2003-05-29  Martin Schulze  <teebaum@cvs.gnome.org>

	* sigc++/signal.h.m4:
	- Remove bogus operator() from unnumbered signal<> and
	  signal<>::accumulated templates.
	- Document the whole thing.

	* docs/index.html: Fix some links.

2003-04-06  Martin Schulze  <MHL.Schulze@t-online.de>

	* TODO, configure.ac, Makefile.am, docs/*:
	Add Doxygen framework.

2003-04-06  Martin Schulze  <MHL.Schulze@t-online.de>

	* sigc++/callof.h.m4, sigc++/adaptors/*, tests/test_callof.cc:
	Move sigc::callof<> to sigc::functor::internal::callof<>.

	* sigc++/functors/mem_fun.h.m4, tests/test_mem_fun.cc:
	Add new types [bound_][const_]volatile_mem_functor, visit_each()
	and mem_fun() overloads for volatile qualifier.
	Add ctor overloads in bound_*mem_functor and mem_fun() overloads
	that take reference instead of pointer.

2003-03-26  Martin Schulze  <MHL.Schulze@t-online.de>

	* Change "closure" to "slot" throughout sigc++2 (file names,
	class names, member variables, documentation, etc.).

2003-03-26  Martin Schulze  <MHL.Schulze@t-online.de>

	* TODO: Rewrite to reflect recent changes as well as recent discussions.

2003-03-24  Martin Schulze  <MHL.Schulze@t-online.de>

	* sigc++/adaptors/bind_return.h.m4: Make the adaptor's data member
	public so that visit_each() can access it.

	* sigc++/adaptors/lambda/*.h.m4: More fixes. Add a note about
	malfunctioning typeof() (probably compiler bug in gcc-3.2).

	* tests/*.cc: Test references. Fix compose equivalent in test_lambda.

2003-03-24  Martin Schulze  <MHL.Schulze@t-online.de>

	* sigc++/Makefile.am, sigc++/functors/functor_trait.h[.m4],
	sigc++/adaptors/adaptor_trait.h.m4: Move detection of function
	and member method pointers' return types from adaptor_trait into
	functor_trait. (We'll use functor_trait rather than adaptor_trait for
	our lambda stuff.) functor_trait.h needs to be generated from .m4 now.

	* sigc++/functors/functor_trait.h.m4: Add convenience macros:
	- SIGC_FUNCTORS_HAVE_RESULT_TYPE indicates that the existance of
	T_functor::result_type should be assumed for all unknown functors.
	- SIGC_FUNCTOR_TRAIT(T_functor, T_result) explicitly specifies the
	result type of a functor.
	("typename functor_trait<T_functor>::result_type") is used to
	determine the return type of our adaptors' operator()() overloads.

	* sigc++/adaptors/[lambda/]*.h.m4: Various fixes in visit_each() and
	operator()() overloads to make these operator()() overloads usable.
	Most of them were just commented out before. Some adaptor types also
	have void specializations, now.

	* sigc++/adaptors/lambda/group.h.m4: Change syntax from
	"[some_functor] % grp([args])" to "group([some_functor], [args])"
	like we agreed on the ml some time ago.

	* sigc++/tests/test_[all adaptors].cc: Test stuff that didn't work
	before.

2003-03-22  Murray Cumming  <murrayc@usa.net>

	* Added pgk-config file, from a mystery person in bug #108857

2003-03-22  Martin Schulze  <MHL.Schulze@t-online.de>

	* tests/test_bind.cc: Test and show how to use functor_trait
	for user defined or 3rd-party functors so that a
	bind<0>([functor],[arg1])() call with no arguments can return a value.

2003-03-20  Martin Schulze  <MHL.Schulze@t-online.de>

	* sigc++/callof.h.m4: Add explanations. Comment in / create templates
	callof_safe[#]. Unfortunately they don't work for functors with overloaded
	operator() so we don't use it for now. At least everything is documented.

	* sigc++/functors/functor_trait.h, sigc++/functors/*.h.m4: Add back
	functor_base compiler hint. We're using it now in adaptor_functor<>.

	* sigc++/adaptors/{adaptor_trait,bind}.h.m4: Make operator() overloads
	with no arguments return the result of the functor invocation.
	Fix multiple bind<0>().
	* tests/test_bind.cc: Test the stuff that's working now.

2003-03-16  Murray Cumming  <murrayc@usa.net>

	* Added sigc++/sigc++.h, like in libsigc++ 1.2
	* examples: Added member_method example, which uses a class method
	and which demonstrates disconnection.

1.9.6:

2003-03-11  Andreas Rottmann  <rottmann@users.sourceforge.net>

	* sigc++/Makefile.am: Use substitution references instead of
	$(patsubst). Is shorter and fixes the strange-dirs-in-dist-tarball
	bug.

2003-03-09  Martin Schulze  <MHL.Schulze@t-online.de>

	* sigc++/connection.h: Add block() capability.

2003-03-09  Martin Schulze  <MHL.Schulze@t-online.de>

	* sigc++/signal.{cc,h.m4}: Add flag signal_impl::destroy_
	and function signal_impl::destroy(). Use them to defer
	the destruction of the signal_impl object during signal
	emission.

	* tests/test_disconnect.cc: Add tests for the connection
	class and for deleting signals during emission.

2003-03-09  Martin Schulze  <MHL.Schulze@t-online.de>

	* sigc++/connection.{cc,h}, sigc++/Makefile.am:
	- New files that add a connection class. Objects of this
	  class are constructed from closure list iterators and can
	  be used to disconnect the refered closure. As opposed to
	  iterators they stay valid beyond the lifetime of the closure.

2003-03-09  Martin Schulze  <MHL.Schulze@t-online.de>

	* sigc++/functors/closure.{cc,h.m4}, sigc++/signal.cc:
	- Rename closure_{base,rep}::[set_]dependency_ -> [set_]parent_.
	- Make closure_rep inherit trackable. This allows for
	  connection objects that stay valid beyond the life time
	  of the refered closure.
	- Make some one-line-functions inline again.

2003-03-08  Martin Schulze  <MHL.Schulze@t-online.de>

	* sigc++/trackable.cc: BUGFIX in trackable_dep_list::clear()

2003-03-08  Andreas Rottmann  <rottmann@users.sourceforge.net>

	* sigc++/Makefile.am: Rewritten so we can build lambda cleanly.
	* sigc++/Makefile.am_fragment: Removed.

	* sigc++/functors/Makfile.am: Removed.
	* sigc++/adaptors/Makefile.am: Removed.
	* sigc++/adaptors/lambda/Makefile.am: Removed.
	* configure.ac (AC_OUTPUT): Remove the above Makefiles.

	* tests/Makefile.am: Re-included lambda test.

2003-03-07  Martin Schulze  <MHL.Schulze@t-online.de>

	* sigc++/signal.{cc,h.m4}:
	- signal_emit#<>: New templates replacing signal#<>::caller.
	  The purpose of these templates is implementing the emit
	  function and optimizing signal emission for the case that
	  no accumulator is used via template specializations.
	- default_accumulator<>: Removed. The default for T_accumulator
	  in signal#<> now is nil. An example how to use accumulators
	  is available in tests/test_accumulator.cc.
	- signal_{base,impl}: Move the implementation of signal_base's
	  interface to signal_impl. An object of this class is
	  dynamically allocated when first connecting a closure to
	  the signal. This drastically reduces the size of empty signals
	  and allows for future addition of a reference counter to make
	  it safe to delete a signal during emission.
	- Directly work on closure_rep during signal emission. This
	  seems to be quicker than using the closure templates.
	- Document the classes. Restructure the header file a bit.

	* sigc++/functors/closure.h.m4: Make closure_base::rep_ data
	member public, so that signal emission can directly work on it.

	* tests/test_size.cc: Add an entry for signal_impl.

2003-03-07  Martin Schulze  <MHL.Schulze@t-online.de>

	* sigc++/functors/closure.{cc,h.m4}:
	- closure_base: BUGFIXES in ~closure_base() and operator=().
	- Mark some functions with the inline keyword. This seems to
          help gcc 3.2 to optimize signal emission and (dis)connection.
	- Document the classes. Restructure the header file a bit.

2003-03-07  Martin Schulze  <MHL.Schulze@t-online.de>

	* sigc++/trackable.{cc,h}: Make trackable allocate a
	trackable_dep_list object dynamically when adding the first
	dependency. (This reduces the size of objects, that are not
	refered by a closure by 4 bytes (50%) and increases the size
	of objects that are refered by a closure by 4 bytes (50%)
	on a 32 bit architecture => This reduces total memory use
	when >50% of the trackables are not refered by a closure.)
	Document the classes.

2003-03-05  Martin Schulze  <MHL.Schulze@t-online.de>

	* tests/Makefile.am, tests/test_size.cc, tests/test_accumulated.cc:
	Add two test cases. test_size is showing the size of  public and
	internal structures. (Which apart from empty signals are smaller
	than the sizes of the equivalent libsigc++-1.2 structures.)
	test_accumulated is a test for the template signal<>::accumulated<>
	at the same time showing the use of accumulators in libsigc++2.

	* Offtopic: My note about binary sizes from 2003-02-10 is wrong.
	Stripped libsigc++2 test binaries are about 8-10k in size.

2003-03-05  Martin Schulze  <MHL.Schulze@t-online.de>

	* sigc++/visit_each.h: BUGFIX in template specialization
	limit_derive_target<T_Target*,T_action>::with_type<false,T_type>:
	Add non-const overloads for static void execute_() avoiding
	compile time errors.

2003-02-16  Martin Schulze  <MHL.Schulze@t-online.de>

	* tests/Makefile.am, tests/test_disconnect.cc:
	Add testcase with a mixed connection & disconnection sequence.

2003-02-16  Martin Schulze  <MHL.Schulze@t-online.de>

	* sigc++/signal.cc: Bugfix in signal_base::insert():
	Set notification function in the newly created copy of
	slot_ rather than in slot_ itself.

2003-02-10  Martin Schulze  <MHL.Schulze@t-online.de>

	* sigc++/signal.h.m4: Comment in typedefs for iterator types in
	the signal#<> class template. Make signal#<>::connect() return an
	iterator for convenience.
	(Note that the first change increases the binary size of
	tests/test_signal from 201k to 204k, the second change to 206k.)

2003-01-23  Murray Cumming  <murrayc@usa.net>

	* sigc++/adaptors/lambda is disable temporarily (not built and
	not distributed) because it gets built before its parent
	directory, but #includes generated sources in the parent directory.

2003-01-22  Murray Cumming  <murrayc@usa.net>

	* Added Andreas Rottman's example.

2003-01-22  Murray Cumming  <murrayc@usa.net>

	* Applied Andreas Rottman's make dist fixes.

2003-01-14  Murray Cumming  <murrayc@usa.net>

	* Added whitespace to make the code more readable.
