Eric Sunshine removed the unused, obsolete, and deprecated top-level <name>
node from the .csplugin files.

Eric Sunshine performed Phase Three of the elimination of the monolithic
scf.cfg:

-*- Eliminated the SCF information which was hardcoded in the .cpp files
of plugin modules, and which duplicated information in the external
.csplugin files.

-*- Plugin modules no longer maintain and export a monolithic class list.
Now, each factory implemented by the code is exported automatically.

-*- Added a new <implementation> child node to the <class> node in
.csplugin files. The value of this node is the name of the C++ class
which implements the SCF class. For instance, C++ class csVFS
implements crystalspace.kernel.vfs.

-*- Eliminated the following SCF macros which were related to exporting
SCF information from .cpp code and/or registering classes manually:

SCF_EXPORT_CLASS_TABLE
SCF_EXPORT_CLASS
SCF_EXPORT_CLASS_DEP
SCF_EXPORT_CLASS_TABLE_END
SCF_REGISTER_STATIC_CLASS_DEP

-*- Eliminated the following methods from iSCF:

RegisterStaticClass
RegisterClassList

-*- Plugin modules are now initialized/shutdown lazily as classes are
requested from them. The first time a class is requested, the plugin
is initialized. The plugin is shutdown after the last class instance
has been destroyed.

-*- Fixed bug in scf.h where SCF_PRINT_CALL_ADDRESS was not being enabled
for gcc 3.x.

-*- Fixed bug in win32.jam where GenerateExportDefs rule failed to ensure
that directory containing output file existed before creating file.
Also fixed bug where it failed to set up a dependency between the
input and output files.

-*- Still To-Do:

- Remove references to scf.cfg and scfreg from documentation. Also
document new .csplugin resources.

- Add platform-specific function to scan and locate plugins
automatically rather than using the ad-hoc approach inherited from
scanning for .scf files.

- Add platform-specific function to query a plugin's meta-information.
This should be used by SCF to do the raw extraction. Provide and
finalize API for higher-level clients to access meta-information.

- Augment static linking to work with the new facility. (Removal of
the hardcoded SCF information, has now broken static linking. It
worked until this time, even with all of the preceding changes.)

Eric Sunshine performed Phase One of the elimination of the monolithic
scf.cfg:

-*- Plugin modules are now self-describing. This information can be
queried at run-time without having to actually load the module.

-*- The plugin maintainer now manages the plugin's meta-information in an
external .csplugin file, rather than hard-coding the information into
the plugin's source code. The mechanism by which the meta-information
is bound to the plugin is platform-dependent. Presently, all
platforms simply lay down the meta-information in a plain text file
alongside the plugin itself; with the same basename and extension
.csplugin. This may change in the future. For example, on MacOS/X,
the meta-information will probably be encapsulated within the plugin's
bundle wrapper.

-*- Plugin meta-information is now maintained in XML format. Here is an
example:

<?xml version="1.0"?>
<!-- gl3d.csplugin -->
<plugin>
<name>gl3d</name>
<scf>
<classes>
<class>
<name>crystalspace.graphics3d.opengl</name>
<description>OpenGL 3D graphics driver</description>
<requires>
<class>crystalspace.font.server.</class>
</requires>
</class>
</classes>
</scf>
</plugin>

-*- Since meta-information is now extensible, maintainers can choose to
publish supplementary information about plugins (in addition to the
SCF information already published). For example, image loading
plugins could publish "image indendification" information which would
allow the image loading multiplexor to selectively request image
loading plugins on-demand, rather than requesting all plugins
unconditionally, even if they are not needed. Here is an example of a
possible meta-information table for the PNG loader:

<?xml version="1.0"?>
<!-- cspngimg.csplugin -->
<plugin>
<name>cspngimg</name>
<scf>...</scf>
<imageloader>
<imagetype>
<class>crystalspace.graphic.image.io.png</class>
<identify>
<mimetype>image/png</mimetype>
<extension>png</extension>
<extension>PNG</extension>
<scan length="4" bytes="\0x89PNG"/>
</identify>
</imagetype>
</imageloader>
</plugin>

In this example, the PNG loader meta-information tells the multiplexor
several different ways to identify a PNG image: by checking file
extension, if available; by checking MIME type, if available; by
checking for the magic-string "\0x89PNG" in the raw image data. If
the multiplexor identifies the image as PNG, only then will it
actually request the PNG loader.

-*- Added the --meta-file directive to msvcgen.pl to allow specification
of the meta-information file for a module. The value of this option
is interpolated into template files via the new %metafile% variable.
msvcgen.mak now utilizes this flag with the value of the new
INC.PROJECT makefile variable. Augmented the MSVC6 and MSVC7 plugin
template files (plugin.tpl) to make use of %metafile%.

-*- Changed the file extension for plugins on MacOS/X from .csplugin to
.csbundle to avoid conflict with new meta-information resource which
uses the extension .csplugin.

-*- Still To-Do:

- Augment SCF to utilize the new meta-information resources, and to
understand the new XML format. Presently, these resources are
ignored at run-time.

- Add platform-specific function to scan and locate plugins
automatically, rather than relying upon a monolithic registry such
as scf.cfg.

- Add platform-specific function to query a plugin's meta-information.

- Eliminate the monolithic scf.cfg.

- Augment static linking to work with the new facility.

- Eliminate the hard-coded SCF registration information in each
plugin's source code.

- made the following changes:
- To the map loader:
- Procedural textures and normal textures are parsed from
the same tag, <texture>.
- Both kinds of textures are loaded in the same manner,
through plugin interfaces ('normal' images are handled by
a loader built into csloader.)
- A 'texture loading context' is passed to a loader,
containing some info such as the image specified in <file>
and texture flags.
- Built a checkerboard texture loader into csloader (this
one is used in case a texture couldn't be loaded
otherwise.)
- Animated images are detected and the ptanimimg plugin is
tried for loading.
- Changed the ClassIDs of the standard PT & animation texture
plugins.
- Fixed the JNG/MNG plugin to better recognize animated real-world
MNGs.
- Augmented csCreateXORPatternImage() to accept an optional color.
- Changed flarge according to the loader changes and added a
yellow checkerboard texture.
- Updated the API mod docs.

Eric Sunshine fixed jng/jngio.mak and jng/Jamfile so that the JNG loader
plugin once again builds. It must now link against csgeom since it
employs csRect.

- made the following changes:
- fixed the stupid mistake of having swapped two operands in a
difference in the animated proctex plugin
- improved error handling in the animated proctex plugin
- added iAnimatedImage::IsAnimated()
- updated the JNG plugin to properly handle animated MNGs
- removed the "circular ref" comments from flarge as there aren't
leaks any more
- added a spinning cube animation to stdtex.zip and used it in
flarge (on the street).

Eric Sunshine made the following changes:

-*- Modified configure.ac so that it emits a SRCDIR property to
config.mak. This value represents the --srcdir argument given to the
configure script (or "." if --srcdir is omitted). This points at the
directory containing the CS source code (which may differ from the
build directory, which is typically the current working directory).

-*- Modified makefiles and build scripts throughout the project so that
they respect $(SRCDIR). This allows the project to be built in a
directory other than the source directory, thus it is possible to
place the source directory on a readonly filesystem (such as a
CD-ROM), or to share a single NFS-mounted source directory among
different builds, where each build inhabits its own directory. For
example, if CS resides at /home/CS and you wish to build the project
in /home/build:

% cd /home/build
% ../CS/configure
% make -k all
% make install

(Note that the Jam-base build system already supports this build
paradigm.)

-*- Modified configure.ac so that it emits EXTENSIVE_MEMDEBUG to
config.mak since this variable is used by Makefile.in for the
`showconfig' target.

-*- Modified configure.ac so that it emits MONITOR_MAKEFILE_CACHE when the
value is either "yes" or "no", instead of emitting it only when the
value is "yes". This was necessary because CS/mk/cache.mak prints the
value of this variable as part of $(SYSMODIFIER).

res2002 2003-02-15 04:07

- checked if the image IO plugins work properly and fixed them
if necessary:
- TGA saving was botched
- JNG saving didn't work right where sizeof(csRGBcolor) != 3
- JNG loader works better with single-frame MNGs
- BMP didn't honor the padding of scanlines to a multiple of 4
- augmented gfxtest to add an alpha channel if none is present
- changed csImageFile::convert_pal8() to ensure the image palette
has at least 256 entries
