/*

 * CHANGELOG.

 */

08282002 - Cleanups in grp.c so that Visual C++ doesn't complain anymore.

08222002 - Fixed ZIP_exists() to work with directories. Now breaks out of

           __PHYSFS_verifySecurity() early if a path element is missing

           (since all the others will be, too)...this check is only done

           if symlinks are disabled, but we might as well save easy cycles

           where we can.

08212002 - Did a couple tedious-for-small-rewards cleanups, optimizations,

           corrections and streamlinings I've been meaning to do. Touched a

           lot of code. One of the side results is that ZIP_isDirectory()

           got fixed.

08192002 - Generalized sorting routines, moved them into physfs.c and removed

           the multiple copies from the various archivers. Adding profiling

           code (currently only for sort routines)...enable it with

           --enable-profiling in the configure script. Fixed incorrect

           behaviours in configure.in.

08172002 - Patched configure.in to work around buggy autoconfs.

08162002 - Fixed QPAK archiver, since I broke it (sorry!). Also fixed a

           qpak memory leak.

08092002 - Added Quake PAK archiver (qpak.c) by Ed Sinjiashvili. Thanks!

           Made (successful?) attempt to fix pthread-to-ui64 cast problem.

           Check for OS/2 in configure.in, in case anyone gets autoconf and

           such to work right on their OS/2 box.

08012002 - Patched win32.c to compile.

07302002 - Minor error handling fix (thanks, Alexander!)

07292002 - Found some memory leaks, thanks to Valgrind (which rules, btw).

           Added Russian translations (koi8-r, cp1251, cp866, and iso-8859-5)

           by Ed Sinjiashvili. Added Spanish translation by Pedro J. Pérez.

           Debian package support in CVS, thanks to Colin Bayer. French

           translation by Stéphane Peter.

07282002 - macclassic.c now returns human readable error messages instead of

           ERR_OS_ERROR. Closing files on MacOS no longer fails if the volume

           info can't be flushed. Minor error message tweak in os2.c. All

           possible human-readable literal strings (including all those OS/2

           and MacOS error messages) have moved to constants in

           physfs_internal.h...this allows the library to be translated to

           other spoken languages fairly easily.

07272002 - Patched the OS/2 code to be useful...works pretty well, now. Added

           makeos2.cmd for building (not an ideal solution, but oh well).

           Initialized some variables in zip.c to prevent compiler whining.

07262002 - Fixed a typo in documentation. Archivers with matching file

           extensions are now given first shot at opening an archive, but if

           they fail, the other archivers are tried. More fixes to zip.c's

           ZIP_enumerateFiles(). Wrote an OS/2 platform driver based on API

           specs and a heavy pounding of Google Groups...as I don't have an

           OS/2 compiler at the moment, it probably doesn't even compile.  :)

07252002 - configure.in and unix.c now deal with platforms that lack a

           functional pthread library. Edward Rudd sent in a patch to the RPM

           specfile to have the build system set the correct version.

           Clean ups in grp.c, beos.cpp and macclassic.c.

07242002 - Rewrote ZIP_enumerate(). Hopefully it sucks less this time.

           unix.c and configure.in now have the infrastructure to disable

           the CD-ROM detection code, and use a stub that successfully (and

           unconditionally) reports no detected discs. Currently this is

           used on AtheOS (which doesn't have CD-ROM support at the moment

           anyhow), but it will be useful to get the library up on odd,

           Unix-like systems that don't use either getmntinfo() or getmntent().

07232002 - Cleaned up the cut-and-pastes in the various file enumeration

           routines and moved it into __PHYSFS_addToLinkedStringList().

           Tons more ZIP file enhancing. I'm fairly certain it's robust and

           fast in every reasonable respect, now. GRP archiver now caches

           the file table...it was generally overhauled like the ZIP driver.

           Added "ls" as an alias of "enumerate" in test_physfs.

           I lied about zip.c's robustness; disabled the enumeration code.

07212002 - More FreeBSD build system patches. Added some new autoconf spew to

           .cvsignore. bootstrap now copies the appropriate Makefile.am

           instead of rename()ing it.

07192002 - Cleaned up configure.in and unix.c so that we check by available

           header to determine the appropriate CD-ROM detection code...this

           should make this more future-proof (and probably get it building

           out of the box on other BSD platforms.)

07172002 - Fixed seeking backwards in ZIP_seek(). Changed the error message

           ERR_TOO_MANY_SYMLINKS to ERR_SYMLINK_LOOP. Patches to build system

           and unix.c for FreeBSD compatibility. Added physfs.spec to

           "make dist" archives (thanks, Edward Rudd!).

07152002 - Symlinks in ZIP archives are detected correctly now, I think.

07142002 - Use GetVolumeInformation() instead of GetDiskFreeSpace() in

           win32.c's mediaInDrive() function. This allows Windows NT 3.x to

           correctly detect CD-ROM drives. Library now appears to be fully

           functional on WinNT 3.51...need to try NT 3.1 still.  :)

           Patches to new ZIP code; cleaned up bugs in symlink reading code,

           but we incorrectly identify some entries as symlinks, which doesn't

           fly...for now, symlink code is commented out, so symlinks look

           like regular files (and reading from a symlink entry gives you

           the link as file data).

07122002 - Rewrote the ZIP archiver to no longer use Gilles Vollant's unzip.c

           code. Losing that abstraction should make the ZIP archiver

           significantly more efficient, and halved the amount of code used.

           Plus, being a control freak, I like my coding style more than

           Gilles's. :)  There are still bugs to shake out, but this is good

           progress.

07112002 - configure.in updated to make it happier on newer autoconfs

           (thanks again, Alexander!). FIXME cleanups.

07102002 - Added a byteorder-friendly convenience API, so you can read/write

           data and convert to the native byteorder without too much effort.

           Upped version to 0.1.7.

           Build system corrections for BeOS and Cygwin (thanks, Alexander!).

           Added RPM specfile for PhysicsFS (thanks, Edward Rudd!).

06292002 - Fixed incorrect error message when opening a file for read without

           defining a search path. LOTS of win32 updates and fixes; lots of

           things that were broken work now, and we are slowly becoming

           more compatible with legacy win32 systems. Builds on Cygwin again.

           All platform drivers (except beos.cpp) had a buffer overflow when

           detecting mounted CD-ROM drives...it only occurs when a drive is

           detected, and it probably won't result in your box getting rooted,

           but upgrade soon anyhow. Readded the .cvsignore files from the old

           build system.

06282002 - Reworked build system _AGAIN_.

06222002 - Alexander Pipelka spotted a bug in the file open routines in

           posix.c; patched.

06152002 - Autoconf build system will now generate shared libraries on BeOS,

           and (supposedly) Cygwin.

06142002 - Rewrote autoconf build system. It now works around the MacOS X bug

           that prevented shared libraries from building.

06112002 - Updated CodeWarrior projects and added them to CVS. _Finally_

           officially released 0.1.6.

06102002 - Major overhauls to platform/win32.c ... should work on all Windows

           platforms, including 95/98/ME and NT/2K/XP flavors. Someone should

           see if this builds on WinCE!  :)  You no longer need the latest

           platform SDK to build it, either; the questionable DLL is accessed

           with LoadLibrary() at runtime now, and handled if not present. This

           now builds correctly on a freshly installed Visual Studio 6.0, and

           the DLL it builds works everywhere. Plus, a bunch of other bugs

           and incorrect behaviours were squashed. Visual Studio 6.0 project

           file added to CVS.

06082002 - Fixes to __PHYSFS_platformEnumerateFiles() in win32.c: cleaned up

           memory leak, handles paths more robustly, and prevents possible

           skipped file entries. Removed AC_C_CONST and AC_TYPE_SIZE_T checks

           from configure.in (not needed, and they broke BeOS build). Clean

           out the docs/ directory when doing a "make dist". Fixed crashbug

           when calling PHYSFS_deinit() more than once in a row. Tried to get

           MacOS X to build a shared library, gave up; I'm doing something

           wrong in my Makefile.am, I think. On MacOS X, running ./configure

           --enable-static --disable-shared works, though. Hopefully someone

           will fix this soon. In unix.c, the Darwin version of

           __PHYSFS_platformDetectAvailableCDs() was free()ing a static

           buffer; fixed.

06072002 - Manpages! Finally installed Doxygen and scratched together a

           Doxyfile. After some revision to physfs.h, we've got a rather

           nice API reference.

06062002 - Fixed __PHYSFS_platformSeek() in archivers/posix.c. Implemented the

           getLastModTime method in archivers/zip.c (returns legitimate info)

           and archivers/grp.c (returns lastmodtime of GRPfile itself in the

           physical filesystem). Put a 64-bit _llseek() version of the seek()

           and tell() methods in platform/posix.c, but you need to hack (or

           rather, fix) configure.in to enable it. From Greg on win32.c: Fixed

           file enumerator function (needed a wildcard '*' specification), CD

           enumeration only reports CDs that have media, getLastModTime() has

           been implemented.

06012002 - Added -Wall to debug builds. Removed ANSI stdio calls from

           platform/posix.c, and replaced them with actual POSIX calls (that

           is, fopen() became open(), fseek() became lseek(), etc...)

05272002 - Added some explicit casts when calling malloc() in platform/posix.c

05252002 - Added John Hall's file modification time patch, and added a

           getlastmodtime command to test_physfs. Corrected error reporting

           for missing files a little bit. Changed build system to only try

           building beos.cpp if on a BeOS system (since we need a C++ compiler

           available to do so). Implemented getLastModTime in macclassic.c.

05242002 - Upped version to 0.1.6 (not officially released yet).

05232002 - Fixed the build system to always package the complete source, not

           just what we built for a given system, when doing a "make dist".

           Updated INSTALL. Wrote BeOS platform code (platform/beos.cpp).

           Split unix.c into unix.c and posix.c. Linux and BeOS both share

           posix.c, although I don't think it's completely POSIX compliant at

           this point (not that it matters much).

05212002 - Cleaned up some FIXMEs.

05202002 - Added .cvsignore files.

05162002 - Edward Rudd also caught an embarrassing screwup by me in

           unix.c: the open-for-append call was using "wb+" instead of 

           "ab" when calling fopen(). Doh! 

05152002 - configure script now deals with systems that have a readline 

           lib, but require it to be linked with curses. Thanks to Edward 

           Rudd for the patch.

05102002 - A trimmed-down zlib 1.1.4 is now included in the source distro, for

           use by win32, MacOS, and Unix systems that don't have it installed

           on the system. Autoconf support! Initial attempt at this. Lots of

           stuff may be very broken.

05082002 - From Greg: More win32 work. Library is now 95% functional on win32.

           Only known win32 problem is that the CD drives are reported whether

           they contain a disc or not).

05062002 - From Greg: Win32 boxes without the latest Platform SDK can now

           #define DISABLE_NT_SUPPORT. Other fixes.

04242002 - Updated win32 info in INSTALL to discuss Platform SDK issues.

04202002 - Added a (very) quick and (very) dirty http server to the

           extras directory (public domain), as another example of using

           the library.

04192002 - Corrected some win32 info in INSTALL. Changed Makefile to 

           package releases as .tar.gz instead of .tar.bz2.

04122002 - Some win32 cleanups and fixes across several files. Upped 

           version to 0.1.5.

04082002 - Fixed problem when calling __PHYSFS_setError before PHYSFS_init.

04062002 - Added MacOS info, etc to INSTALL. Patched unix.c and 

           test_physfs.c to compile on Darwin again.

04052002 - Added byte ordering API. Byte ordering fixes in grp.c, and some

           cleanups in unzip.c. Mac work is more or less complete.

04042002 - Mac work continues. Almost complete, now. test_physfs now has

           tests for write, append, and filelength, and most of the

           commands can tolerate a quoted argument (although this is

           hacky, it's good enough for these purposes). Upped test_physfs

           version to 0.1.1. Added a malloc-failure check in the Unix

           CD-ROM detection code.

04032002 - PHYSFS_init always makes sure the calling thread initializes its

           error state. Win32 codebase is updated with mutex implementation

           (thanks, Greg!).

04022002 - Mac work continues. Found a bug where we put a double dir

           separator in if we had to resort to the fallback userdir (if

           __PHYSFS_platformGetUserDir() returned NULL to calculateUserDir().

           Made note of potential infinite recursion in platform driver docs.

04012002 - (_NOT_ an April Fool's Joke:) Started working on MacOS Classic

           port. Added skeleton.c to platform directory. Minor patches to

           get things compiling on Mac (notably, DirInfo conflicts with

           a type exposed by MacOS's namespace-polluting API, and some

           typecasting issues). Found a call to ferror() I had missed in

           unzip.c.

03302002 - Mutexes! PhysicsFS should be thread safe now, so long as you 

           don't try to do something like close a file at the same time as

           you are reading from it in another thread. All reasonable race

           conditions should now be gone, but the new code will need some

           eyeballing before we install it on life support systems or anything.

           The mutex abstraction is implemented in unix.c, win32.c will be

           updated shortly.

03292002 - Fixed a potential problem in ZIP_realpath() and some byte order

           issues in zip.c. Converted unzip.c to use physfs file i/o

           abstractions. Converted CHANGELOG to list latest entries first.

03242002 - Added __PHYSFS_platformInit() and __PHYSFS_platformDeinit(). Win32

           improvements by Gregory S. Read. Added PHYSFS_[us]int(8|16|32)

           types...this breaks binary compatibility with previous PhysicsFS

           releases! Added platform specific i/o functions, so we don't have

           to rely on stdio anymore. Updated TODO with my comments on the

           physfs mailing list. 1.0, here we come! Removed race condition from

           grp.c and converted to file i/o abstraction layer calls from stdio.

           Tons of other fixes and enhancements. 

03202002 - Patched platform/win32.c to compile.

03152002 - PHYSFS_setSaneConfig() now handles failure to set the write dir

           better. Patched makefile to link the test program. Changed all the

           "write" functions to get data from a "const" buffer. Added an

           "extras" dir, which currently contains PhysFS->SDL_RWops glue code.

03052002 - Made unix.c's timeslice implementation more portable, and added a

           Darwin-specific means to detect CDs (thanks to Patrick Stein).

           Minor cleanup in win32.c (changed "for (; condition ;)" into

           "while (condition)" ...)

11142001 - Removed a redundant error check in platform/win32.c

10092001 - Syntax fixes in dir.c, a FIXME in grp.c, and a "cat" command in

           the test program. Apparently I had accidentally removed a rather

           crucial line from dir.c a few revisions ago, and no one noticed. :(

           Fixed. The win32 userdir will default to the base dir, now.

09252001 - Changed API: PHYSFS_setSaneConfig() takes an organization name, and

           sets up less directories. Be warned. Fixes from David Hedbor: 

           make setSaneConfig() set write directory correctly if it had to 

           create the directory, and make sure that the writing functions

           get used in dir.c when a file is opened for writing/appending.

           Updated CREDITS.

09142001 - David Hedbor submitted a patch to handle a case where the

           current working directory has been deleted out from under the

           process (both in platform/unix.c and physfs.c itself). Thanks,

           David! Added a CREDITS file. Changed the format of the author field

           in PHYSFS_ArchiveInfo to put the email address between "<>" instead

           of "()" chars. Updated TODO. make install now deletes previous

           revisions of the library. Changed version to 0.1.4.

09012001 - Happy September. Moved the Visual C project files and the zlib

           source to a separate download. Look for it at

           http://icculus.org/physfs/downloads/physfs-win32-support.zip ...

           Updated the INSTALL doc for Win32 building. Rewrote win32.c's

           __PHYSFS_platformRealPath() to not rely on Visual C's runtime lib,

           which was the last Cygwin incompatibility (although the Makefile

           needs to be updated to build a DLL under Cygwin). Tinkered with the

           Makefile a little, but it needs more work. Started working on a

           MacOS version. All I have is CodeWarrior 4, which is way out of

           date, and (for what is supposed to be an ultra-user-friendly

           environment) is completely uninituitive to me. Still, managed to

           get most everything compiling, which improved the quality of the

           code somewhat). Haven't tried to compile the zipfile support, and

           I still can't link the library. Dunno what the hell I'm supposed

           to do there. Isn't Unix supposed to be hard compared to this?

08312001 - Built PhysicsFS on Mandrake 8.0 for the PowerPC. Compiles clean,

           but there's at least one byte-ordering issue in zip.c that needs

           to be fixed.

08292001 - win32.c calculates the base dir with GetModuleFileName() first, now,

           and falls back to SearchPath() if there were problems. Changed an

           occurence of _MAX_PATH to MAX_PATH, so both CygWin and Visual C can

           handle it.

08282001 - win32.c now checks HOMEDRIVE, HOMEPATH, and HOME when calculating

           the userdir. Added include files that make it a little closer to

           compiling under Cygwin. Added a TODO file. Fixed unix.c's

           __PHYSFS_platformCalcBaseDir() so that it actually works. Fixed

           Makefile so that it links the test program properly.

           Changed version to 0.1.3.

08232001 - Fixed a potential free()ing of a NULL pointer in

           __PHYSFS_platformEnumerateFiles() in platform/unix.c. Added

           platform/win32.c. Other cleanups to get this compiling with

           Visual C and CygWin. Added BAIL_MACRO for times when we were doing

           BAIL_IF_MACRO(1, ...). Abstracted mkdir() in the platform drivers.

           Added GRP setting output to showcfg in the Makefile. Updated INSTALL

           with license info and Win32 build instructions. Dependency on the

           readline library in test_physfs.c is now optional.

           Changed version to 0.1.2.

08072001 - Changed version to 0.1.1.

08062001 - Added CD-ROM detection code to the unix platform driver.

08012001 - Added a safety memset in error setting, fixed URLs and email addr.

07282001 - Initial release.
