Enable arm64 for non-Windows targets (thanks, pastdue!). Co-authored-by: Victor Romero <romerosanchezv@gmail.com>

android: PhysicsFS now has actual Android support. This compiled and worked on Android before, if you didn't care about PHYSFS_getBaseDir() and PHYSFS_getPrefDir() being useful. Now you can pass PHYSFS_init() some necessary Android objects to solve this. Passing NULL to PHYSFS_init is acceptable and will simply report "/" for the base dir and prefdir, under the assumption that the app queried the OS for these directly instead.

7z: Make error handling a little more robust.

7z: copy/paste error in error checking, found by static analysis. This was clearly copied from a previous line but wasn't updated with the correct condition to check, so if malloc() failed, it would dereference NULL instead of reporting an error.

Move buildbot script changes to stable-3.0 branch.

buildbot-emscripten.sh: Look for the SDK at /emsdk by default.

buildbot-checker.sh: Just require scan-build to be in the $PATH.

Modern buildbot vocabulary is "worker," not "slave."

Have static analysis script use Ninja.

Fixed mishandling of an allocation failure in PHYSFS_openRead(). (Static analysis caught this one! Thanks clang!)

PHYSFS_flush() shouldn't call PHYSFS_Io::flush(). The former is meant to send PhysicsFS-buffered data to the PHYSFS_Io's implementation, the latter is meant to tell the OS to definitely make sure the data is safely written to disk (or at least, that's what it does in practice). This was making PHYSFS_setBuffer()'d handles _slower_, since they would end up blocking whenever the buffer was full until the data made the full trip to physical media, instead of just letting the OS do its own buffering. Now we still PHYSFS_Io::flush() on PHYSFS_close(), like this has always worked. That might also be overkill, but that remains a historical artifact of trying to keep the underlying file handle usable if pending writes fail for possibly-recoverable reasons (which isn't guaranteed if you just close() it, at least as far as I remember).

Fixed seeking within read buffers.

Simplified doBufferedRead(). No longer recurses, and deals with EOF correctly.

Fixed PHYSFS_flush().

OS/2: Patched to compile.

OS/2: Deal with UTF-8 -> codepage conversion on older OS/2 installs. (untested attempt.)

OS/2: don't report failures on Unicode conversion on older OS/2 installs.

vdf: Don't add directories; UNPK_addEntry()/DirTree will fill in parents.

Allow physfs.pc generation on mingw-w64 and osx homebrew/etc, Rename physfs-static to physfs on mingw-w64

Made PHYSFS_caseFold() a public API.

Added some warnings to the docs about converting bad Unicode strings.

unicode: Added UTF-16 and UCS-4 stricmp functions.

OS/2: Fixed NULL pointer dereference.

Clarified some documentation.

Updated PHYSFS_Archiver with PHYSFS_EnumerateCallbackResult change.

Make PHYSFS_EnumerateCallback return an enum instead of an int.

windows: Disable _CRT_SECURE_NO_WARNINGS again.

Cleaned up some header inclusion politics.

qnx: Added more proper support for QNX.

Bump version to 2.1.1, since we've been at 2.1.0 for 8.5 years. :) There isn't going to be an official 2.1.1 (or 2.1.0) release; we'll let this marinate a little and jump to 3.0!

physfshttpd: serve up directory listings, a few other cleanups.

physfshttpd: removed deprecated PHYSFS_getLastError() calls.

Fixed one more Visual Studio compiler warning.

Whoops, patched to compile.

Fixed some compiler warnings on Visual Studio. (and maybe made a few new ones...)

Fixed some warnings that Xcode brought up.

Updated TODO.txt

zip: add some zip_resolve() calls, deal with DirTree-inserted parent dirs.

This appears to have been fixed at some point.

Don't fail enumeration if a directory isn't available in a given archive. That shouldn't be a fatal error, that's a normal case.

Little tweaks to __PHYSFS_initSmallAlloc().

Fix symlink filtering for enumeration under a virtual mount point.

Make PHYSFS_exists() work with mounts from PHYSFS_mountIo(io, NULL, ...) (Actually, from any mount function that accepts a bogus/NULL filename.)

Don't set readonly if PHYSFS_stat()'ing something not in the write dir. This API is meant to report what the archivers think about an item and not actually tell you if a PHYSFS_openWrite() will succeed on it.

Turns out we were doing this for a (maybe not good, but reasonable) reason.

Archivers can now specify whether an archive definitely was intended for them. So if a zip file goes to the zip archiver but is corrupted, the system can now know not to bother trying other archivers once the zip archiver has had a shot at it, and just as important: it can report the real error from that archiver instead of a generic "unsupported."

Reduced some FIXME-3.0 tags to normal FIXME. They can wait.

Sanity check archivers that should only have low-ASCII filename.

Filled in more documentation.

7z: do global initialization once without risking a race condition.

PHYSFS_setSaneConfig uses enum callbacks now.

Improved some documentation.

Patched to compile on various platforms and compilers.

Don't mark the PHYSFS_EnumFilesCallback _typedef_ as deprecated. It upsets several compilers when building PhysicsFS itself.

Updated docs to use PHYSFS_getLastErrorCode() instead of PHYSFS_getLastError(). (a few other documentation fixes probably slipped in here, too.)

FIXME removal: document enumerateFiles() sorting promises.

Added some FIXMEs and deprecated PHYSFS_getLastError().

Reworked enumeration to be more powerful. Now callbacks can stop further enumeration and report errors, if they had a catastrophic issue or just found what they needed and don't need to process any more items. Also, the actual enumerators can report errors instead of silently dropping items. This led to several other fixes as all these implementations got audited and reworked. The original, non-callback enumerator now returns NULL if it can't produce a complete list instead of dropping items and returning a partial list.

Removed __PHYSFS_stricmpASCII functions. Nothing was using them, except one OS/2 thing that could live with stricmp.

Made physfs_lzmasdk.h's include-once blockers match other files' formatting.

ignorecase.c: use PHYSFS_utf8stricmp() now.

utf8: big improvements to case-insensitive UTF-8 string compare. - Dramatically reduce RAM usage: uses between 8 and 11 kilobytes less static memory for its internal case-folding tables. - Actually works now. It would fail unconditionally if a codepoint folded into multiple codepoints, even if the compared string contained those exact codepoints. - Now a public API! - Removed __PHYSFS_utf8strnicmp(): nothing was using it, it was incorrect anyhow, and what does 'n' represent when either string might case-fold to something larger in-flight, anyhow?

FIXME removal: this code is fine, I guess.

haiku: CD-ROM detection should report any mounted volume on a B_CD device. Most discs only use the "raw" device, but it turns out the Haiku installation "anyboot" images don't, and those would fail to detect here. If there's some multi-partition disc thing and the OS mounted each separately, we should report each of them.

FIXME removal: it's okay for the PHYSFS_Io to be NULL here. We use this technique in several other places, too.

apple: Patched to compile on XCode versions < 7.

windows: minor cleanup.

apple: Start using some Cocoa APIs, clean up a few related things.

Rename physfs_platform_macos.c to physfs_platform_apple.m It's not really "macOS," it's all of Apple's platforms (iOS, watchOS, tvOS...AppleCarOS? heh), and second...we're about to need access to Cocoa APIs, so we need it to be Objective-C. I fought as long as I could. :/

cmake: Pacify warning about Policy CMP0042 not being set.

Fixed compiler warnings on GCC.

Fixed compiler warnings on Visual Studio.

Marked a bunch of things as "FIXME-3.0" that I want resolved before 3.0 ships.

Removed some FIXMEs that aren't valid.

windows: Patched to compile! (...?)

windows: (maybe) patched to compile on Visual Studio.

PHYSFS_File buffering now uses size_t. This lets you have the full address space but not take up unnecessary space on 32-bit platforms...not to mention removes a bunch of typecasting.

windows: PHYSFS_FILETYPE_OTHER files now report real filesize in PHYSFS_stat(). I don't know if it's _meaningful_, but if the OS reports it, so do we.

Add basic atomic operations for refcounting, etc.

physfshttpd: deal with write errors on the socket.

__PHYSFS_platformDeinit() should return void. What are you going to do if this fails, anyhow?

windows: Removed (what I think is) a copy/paste error.

windows: Use a real synchronization primitive for CD detection thread init. Before we were waiting on a volatile int in a tight loop with a Sleep(50).

More FIXME cleanups.

Make compile-time asserts more readable.

FIXME removal: This is an appropriate error code already.

Removed FIXME: this was already fixed at some point.

os/2: Patched to compile (?).

os/2: attempt to get cpuid support on OpenWatcom builds.

windows: Patched to compile.

windows: Just pass HANDLEs around instead of wrapping in a struct. We don't need the "readonly" field of this struct, because it was only used to protect flushes on non-writable handles, but PHYSFS_flush() also keeps track of what's read-only and won't call into the platform layer anyhow. HANDLEs are typedef'd to be "void *" on Windows, so this is safe (so long as we check for INVALID_HANDLE_VALUE, which is ((void*)-1), when creating new handles.

windows: Fixed logic bug.

windows: better test for WinRT vs win32 (...I think...?)

Updated Unicode case folding support to something 10 years newer. :)

Fixed compiler warning.

WinRT: Disable harmless (in our case) linker warning.

Added an assert for a FIXME that is now handled elsewhere.

Fixed building for WinRT via CMake.

Serious cleanup and update of Windows RT support. This compiles for WinRT, but isn't otherwise tested at all yet.

Minor cleanup.

Some minor preprocessor nitpicks.

unix: getmntinfo() should proabably be set to MNT_NOWAIT to avoid blocking.

Minor QNX fix; don't warn about CD-ROM support (for now).

Apple refers to "Mac OS X" as "macOS" now.

Rename __PHYSFS_Archiver_SZIP to __PHYSFS_Archiver_7Z.

Minor documentation updates.

A couple of fixes for physfshttpd.c.

Fixed a comment about SDL licensing.

Removed SWIG bindings.

Update filename comments.

Renamed all the sources to start with "physfs_" So now you can drop this into your program and not worry about filename conflicts, or where "platform_unix.c" came from in the debugger, etc. Also renamed the "beos" sources to "haiku" and "macosx" to "macos" to match modern platform names.

Add platform_os2.c to the CMake file.

Minor code cleanups: whitespace fixes, 80-column overflows, wrong comments.

vdf: Migrated to new, improved unpacked archiver infrastructure.

Added some TODOs to the ISO9660 code.

Some improvements to INSTALL.txt.

Fixed compiler warnings.

Removed unused variable.

unpacked: let archivers specify create and modified times, hook up to iso9660.

unpacked: let archivers "abandon" the archive instead of closing it. This lets you preserve the PHYSFS_Io in case of error during archive opening.

iso9660: rewritten and simplified. This now builds on top of the "unpacked" archiver and reads only the structures it needs, serializing the parts it cares about. Lots of other cleanups. Lost a little bit of functionality, to be restored later.

unpacked: Don't list a position or length for directory entries.

DirTrees and unpacked archives shouldn't demand a count of entries for init.

slb: be more aggressive about rejecting non-SLB files.

Attempt to fix compilation against the latest Windows SDK.

It's not messy to compile NOW. :)

Removed C++ single-line comments from LZMA SDK.

Disable unaligned reads in LZMA SDK; it upsets GCC's strict-aliasing rules.

Whoops, forgot to add the file. :)

Removed warning in LICENSE.txt about PhysicsFS 0.1.9 being LGPL code. The license was changed in 1.0.0, on January 8th, 2004. I think it's time to stop worrying about a prerelease version from almost 14 years ago.

LZMA SDK is now public domain, remove the LGPL warning in LICENSE.txt.

Removed ancient LZMA SDK.

Rewrote the 7zip archiver. This also updates the LZMA SDK to something more modern, which is now public domain code, and squashed it into a single header for easier building.

zip: fail with correct error code if opening a directory.

Corrected reported value for unknown PHYSFS_stat() access times.

test_physfs: added a "cat2" command to read from two open file handles at once.

Reworked the "unpacked" archivers to use DirTree. This cleaned up a lot of code and improved things, and also allowed a lot of the restrictions on unpacked archivers to be removed.

Moved ZIP tree management up to a higher level, to be reused elsewhere.

Fixed some comments.

Reenable QPAK support by default.

Removed SWIG ifdefs in physfs.h

Fixed more Visual Studio compiler warnings.

Fixed some compiler warnings with Visual Studio.

Fixed compiler warnings on Visual Studio about const qualifiers.

Turn off MSVC anti-portability propaganda in test program.

Removed leftover test scripts from removed SWIG bindings.

Move headers around to get those MSVC anti-portability nags to go away.

unix: OS-specific paths should also chop filename off base path.

Debian/kFreeBSD should use the FreeBSD-specific codepaths, not generic Unix.

Fix lzma option in CMakeLists.txt

Cleaned up what symbols are exported from the library.

Cygwin has mntent.h, and no need to check for CMake tests now.

Maybe macOS needs -fno-common ...?

unix: Don't #error if no CD-ROM support, because we already give a #warning.

Remove -pthread argument.

Updated INSTALL.txt to more closely reflect reality.

Removed BeOS support (Haiku still supported, though!). Since Haiku has pthread support, dropped the BLocker code and use the pthread code from platform_posix.c instead.

Removed __PHYSFS_platformSetDefaultAllocator(); nothing uses it now. We can pull it back from revision control if something needs it later.

mac: Removed Carbon header include and custom allocator (just use malloc).

Simplify CMakeLists.txt, etc. Try to test things with preprocessor macros instead of CMake, and get rid of silly options like turning off thread safety.

vdf: make private functions static.

The archiver options in the CMake file should disable, not enable. We now try to compile all archivers by default unless one explicit disables them individually, so these options needed to be handled differently.

macOS only needs to link against CoreFoundation, not Carbon.

Don't rename the static library on Windows. "physfs.lib" will also be the import library's name, so it's best to leave it separate on that platform.

Added some option information to the CMake output.

Fixed building on MingW.

Patched to compile on BeOS/Haiku.

Checking if this #pragma pack works better on gcc 2.95.

Don't try to build CD-ROM support on Emscripten.

Replaced sprintf() calls with snprintf().

Pacify compiler warning.

Updated TODO: zip64 support has been in for awhile now.

Patched to compile on Windows.

windows: (re)added support for symbolic links.

Added buildbot-raspberrypi.sh and fixed some other buildbot script things.

Added buildbot-emscripten.sh, fixed up some minor things in buildbot-os2.sh.

buildbot-os2: zip to subdir to avoid tarbombing.

buildbot-os2.sh: still trying to get this path right...

buildbot-os2.sh: fixed some paths.

buildbot-os2.sh: Zip to a specific filename.

buildbot-os2.sh: build with full optimizations, zip up final library.

buildbot-os2.sh: actually report an error code.

Added script to run Clang static analysis.

Added a quick script to cross-compile to OS/2 from Linux with OpenWatcom.

Turn on all the archivers by default. (Except for the lzma archiver, since it needs a bunch of external code.) The difference in binary size, for Linux/amd64 compiled for size (-Os), is 4 kilobytes. It's senseless to not just compile them all in.

Added Francesco Bertolaccini to the credits.

Updated TODO.

OS/2: actually working again, now.

OS/2: more work on getting this to compile.

Patched to compile with C89 compilers.

OS/2: implemented Unicode support, modernized platform_os2.c's code. (untested.) Implemented Unicode support, ripped out old APIs that aren't used any more, corrected some things.

Cleanup BAIL_* and GOTO_* macros to be less cluttered. This also fixes really aggressive compiler warnings about the "if (!ERRPASS)" construct producing unreachable code.

OS/2: base dir needs to end with a path separator.

Fix some endlines.

OS/2: fix up the base/user/pref dir code. There might be better ways to do this in modern times than shove it all into the base dir, though.

Patched to compile with OpenWatcom.

Patched platform_os2.c to compile.

Watcom C should include malloc.h to make the alloca macro available.

os2: added OS/2 support back in. With the release of ArcaOS, this is a live platform again. This code probably doesn't compile yet; I've just given it a first shot at resolving the changes between the last OS/2-supported revision and now. This still needs Unicode support added in any case.

vdf: Remove unused chunks of code, fix endianness.

Remove unused variable.

Changed some URLs from http:// to https://, where supported.

Add support for VDF

Fix bug with copying z_stream objects around in zip archiver (thanks, Andrei!). zlib expects us to use inflateCopy() to move a z_stream, then inflateEnd() the original, and apparently fails in later versions if you just try to memcpy() it. This is only a bug in the stable-2.0 and stable-1.0 branches; we replaced zlib with miniz on the development branch, which doesn't have this requirement (or an inflateCopy() function at all!).

Update copyright date.

Updated copyright to 2017.

Removed unused variable in extras/ignorecase.c ...

Added a mostly-harmless FIXME.

Added support for password-protected .zip files. To use: mount a .zip file as usual, open a file as usual, but append '$' plus the password to the end of the path, like so: PHYSFS_File *f = PHYSFS_openRead("/path/to/my/file.txt$MyPassword"); Note that this is the "traditional" PKWARE crypto, like you might get from PkZip 2.04g or Info-ZIP. They have more advanced cryptography in the modern .zip spec, but that's not implemented here. If you've ever tried to unzip an archive and were prompted for a password, you probably saw the traditional crypto at work. Note that this is NOT a secure thing: if you ship an app that contains a password, someone with a debugger can retrieve it. Note also that this password could be available to any code registered as a PHYSFS_Archiver, and that due to how archives combine into a single file tree, the wrong archiver can get the password, at a minimum causing it to fail because passwords don't match. In short: make sure you know what you're doing before you use this!

Platform deinit should happen last, since other deinit bits might depend on it.

Fixed miniz code that triggers recent GCCs' -Wmisleading-indentation.

Removed one more rude thing from the comments. :/

extras/ignorecase.h: Fixed some typos.

Fixed some documentation typos (thanks, Paul!).

Replace unsigned long cast with cast to size_t (thanks, David!). When targeting MinGW-w64's x86_64 target, unsigned long is 4 bytes but void* is 8 bytes. This mismatch triggers the pointer-to-int-cast warning. (This patch was originally David Yip's work, with uintptr_t instead of size_t).

Remove unused functions and variables in platform_windows. Under gcc 5.3.0, the presence of these functions and variables generate unused function / unused variable warnings, which in combination with -Werror causes a compile error.

Remove unused variable in zip_hash_ancestors. Under gcc 5.4.0, this generates unused variable warnings, which in combination with -Werror causes a compile error.

Updated byte order tests to match what SDL does now. That is: you're more likely to be on Linux or a little-endian machine, so deal with the non-Linux bigendian as the exceptional case.

HTTPS all the things.

zip: Reworked how we organize ZIP entries. We now use a hashtable for lookups of specific paths, and organize the entries into a directory tree. The end result is fast lookup and fast enumeration without having to search a sorted array or tapdance with substrings...which means the rare, mysterious bug where we failed to find an existing file should be gone now, too.

Fixed a comment.

Move __PHYSFS_strdup() declaration up with other string helpers.

zip: Don't allocate a 256k buffer on the stack for zip64 parsing.

Added a minor comment.

Replaced PhysFS.NET with a README pointing to more modern C# bindings.

Updated Copyright.

Updated copyright.

Fixes to SDL_RWops bridge code. - Correct return values (number of objects, not bytes), thanks Reto! - Updated for SDL 2.0 RWops interface. Threw away SDL 1.3 support. - 1.2 support remains. For now!

Fixed compiler warning about unused variable because assert() is awful.

Removed a few tabstops to test something on the Mercurial server.

Fixed incorrect logic ("!x != 5" instead of "x != 5"). Thanks to Xian Nox for pointing this out!

Added some FIXMEs.

dos2unix'd platform_winrt.cpp

Removed some tabs and an extra semicolon.

Added Martin Ahrnbom to the credits.

Added support for WinRT 8.1 Universal Apps. Hopefully this will work on Win10 as well... Only time will tell! Here's what's changed: 1. Added a platform_winrt.cpp file. It's based on platform_windows.c but has some WinRT-specific changes. 2. Changed physfs_platforms.h to define PHYSFS_PLATFORM_WINRT when running on WinRT. PHYSFS_PLATFORM_WINDOWS should also be defined, as WinRT behaves a lot like "normal" Windows and this flag is tested against in multiple parts of the PhysFS source code. 3. Changed platform_windows.c to not be used when PHYSFS_PLATFORM_WINRT is defined. 4. In order to work on Windows ARM devices, I had to change in physfs_internal.h, to include _M_ARM as a flag for running on ARM as "ARM" and "__arm__" aren't defined when running on a Windows ARM device. What I've tested: * Setting up a "sane folder configuration" * Reading and writing files * Mounting zip files * Using seek & tell * Checking file length All of these work fine. I couldn't get the actual test software to run on WinRT, but it seems like eveyrthing's working. I've tested these things on my Windows 8.1 computer, as well as my Lumia 920 which is currently running Windows 8.1.

Make sure read buffers get reinitialized before refilling (thanks, Michael!).

Make static analysis happy.

Fixed resource leak when failing to mount a file that isn't an archive.

The stable-1.0 branch didn't support Unicode at all.

Short circuit case-insensitive compare of two equal Unicode codepoints.

PHYSFS_enumerateFiles() actually promises sorting order, and always has.

Backport from default branch: corrected PHYSFS_enumerateFiles() documentation. (transplanted from aaa1204a4426c5412d9c2814e41e0b7066db060c)

Backport from default branch: corrected PHYSFS_enumerateFiles() documentation.

Fix NULL flush() in PHYSFS_Io crash

Static analysis fixes backported to the stable-2.0 branch.

This returns -1 on error, not zero. :/

PHYSFS_stat() returns zero on error, not -1.

We always use miniz now.

Renamed a function to make Clang static analysis happy. "Object leaked: allocated object is returned from a function whose name ('cfallocDesc') does not contain 'Copy' or 'Create'. This violates the naming convention rules given in the Memory Management Guide for Core Foundation" (it doesn't actually leak, but okay, it's a reasonable naming convention.)

Added a FIXME.

Fixed a single-line comment.

Updated installation notes.

Added pkg-config support (thanks, Jonas!).

Better basedir detection for various Unix platforms.

Backport to stable-2.0: don't fsync read-only files.

Don't fsync() read-only filehandles (thanks, Andreas!). This sounds harmless, but it actually forces a write of the inode's atime, which means a lot of painful and unnecessary disk i/o on some filesystems. Should be a good speedup on games that read a lot of small files on Unix.

Fixed memory leak.

Fixed off-by-one error in findBinaryInPath() (thanks, Dmitry!). This bug is new to the development branch, and doesn't exist in either the stable-1.0 or stable-2.0 branches.

Get rid of array of static archivers.

Rearranged PHYSFS_Archiver struct.

Removed comments added by Captain Obvious.

Cleaned out "exists" nonsense in openRead() API.

Remove __PHYSFS_setError(), use the new public API instead.

Cleaned out the "exists" nonsense in the stat() API.

Moved supportsSymlinks into PHYSFS_ArchiveInfo.

Comment tweaks (FIXME additions, typo corrections, etc).

Centralize responsibility for filtering symlinks during enumeration.

POSIX version of __PHYSFS_platformStat() now reports symlinks correctly.

Allow application-supplied archivers. This lets an application supply its own archivers, where they will work like any built-in archiver. This allows abstract directory interfaces the same way that PHYSFS_Io allows stream implementations. This is a work in progress still. The API is still changing, and will remain at version 0 until it is finalized (a theoretical future version 1 will be for when the final public interface changes, not when we evolve the initial API design).

Make __PHYSFS_utf8stricmp() work like you'd expect.

Cleaned up some simple comments.

Perhaps the note about Quake 3 is getting a little dated.

Only check for pthread library if pthread.h was found.

From stable-2.0: explicitly check for pthread library, and link against it.

Updated TODO

SLB archiver

Disable CD-ROM support on Android for stable-2.0 branch.

Turn off CD-ROM support on Android.

Updated TODO.txt.

Remove SWIG stuff from build. This is never going to work well everywhere. I'll leave the SWIG stuff elsewhere, though, for those that want to build their own bindings.

Use .tar.bz2 on this branch, too.

Lowercased most of the CMake project file.

Explicitly check for pthread library, and link against it.

Tagging 2.0.3 release

Use .tar.bz2 for "make dist" instead of .tar.gz Mercurial's tgz archiver is writing the full output path into the archive, causing things like 7-zip to uncompress it to "Users/icculus/projects/physfs-2.0.2.tar" instead of just "physfs-2.0.2.tar". It seems reasonable to believe everyone has .tar.bz2 support by now anyhow.

Added Lauri Kasanen to the CREDITS for a last-minute 2.0.3 patch.

Constify the archivers pointers. These were writable for no reason, taking up .data space.

Bumped version to 2.0.3.

Bumped copyright year.

Fixed warning on iOS

Fixed infinite loop (thanks, Sam!)

Stupid fix for zip_find_entry().

Don't look for libhistory. Apparently libreadline provides this now (maybe it always did?), and it fixes things on OpenBSD. (transplanted from d842cd8c9f9156f24d3776cb9b97f0ae051c88c0)

Don't look for libhistory. Apparently libreadline provides this now (maybe it always did?), and it fixes things on OpenBSD.

Check for alternate __unix__ predef.

An attempt to make this more Unix-friendly.

Backport from default branch: clean up the thread ID mess in platform_unix. Backported from hg changeset f254870dd7dd.

Turns out the CoreFoundation API is way simpler. Fixed assertion, too.

Patched to compile on Mac OS X.

For iOS, build the Mac OS X platform code, not the generic Unix code. Also removed some Carbon calls; use CoreFoundation instead. These functions exist in all versions of Mac OS X and iOS, and replace the Mac OS Classic APIs we were previously depending upon.

Fixed logic bug (thanks, Sam!).

Fixed non-Zip64 .zip files.

Don't sort if there's nothing to do (prevents array underflow, too). (transplanted from 662a7e180c480ff7731493b688aee27e8e010887)

Don't sort if there's nothing to do (prevents array underflow, too).

Fixed var that should be 64 bits instead of 32 now.

Removed a '//' comment.

Added Zip64 support to the .zip archiver. Now we can handle .zip files > 4 gigabytes, etc.

Added getmointpoint command to test_physfs.

Moved PHYSFS_ArchiveInfo into PHYSFS_Archiver.

Add binary compatibility to PHYSFS_Io.

Moved some functions around. We want the #undef malloc, etc, lines as close to the end of the file as possible, and __PHYSFS_readAll() not in the middle of the allocator code.

Better cleanup if PHYSFS_init() fails halfway through.

Made archiver list dynamic, in preparation for external archivers.

Removed "dvoid" typedef.

Fixed Doxygen typo.

Updated docs on PHYSFS_setSaneConfig().

Changed enum typedef to make this Doxygen-friendly.

Fixed comment.

Make Doxygen ignore PHYSFS_DEPRECATED.

Renamed PHYSFS_Archiver::dirClose() to PHYSFS_Archiver::closeArchive().

More FIXME cleanup.

Another FIXME.

FIXME cleanup.

More FIXME cleanup.

Favor /proc/self/exe over argv[0] on Linux, to match other platforms. We don't favor searching the $PATH, though, since that relies on argv[0] too.

Make sure base dir always has a dirsep at the end of it. Now the higher level doesn't have to check for this and realloc the string.

test_physfs's "stat" command now respects unknown file times (-1).

Updated TODO.txt

Moved QPAK support into archiver_unpacked.c More dupe code removal, and more functional generic backend code!

Minor tweak.

Removed archive description macros, moved those strings inline.

Changed so that this builds a reasonable default with no command line #defines. That is, it now builds .zip and native dir support, and that's it.

Removed a bogus FIXME.

Allow Windows to read/write more than 4 gigs to a file in one shot. Removes a FIXME, but the fix probably won't ever get used. :)

Renamed __PHYSFS_utf8strcasecmp() to __PHYSFS_utf8stricmp(). This matches style of other function names we use.

Fixed a typo in the docs.

Removed a FIXME: actually, the code DOES set an error, as far as I can tell.

Removed a FIXME. I assume that Win95 didn't allow large files, so this concern probably wasn't ever valid in any case. Still, Win95 support has been dropped, so it doesn't matter.

Removed a FIXME.

Windows: Use cross-thread Critical Sections instead of cross-process Mutexes.

Removed fallback for systems that have no userdir. This would try to build something under the basedir for Windows 95, OS/2, etc, but those targets are gone now. Modern systems provide this. If a given system can't in the future, they can pull this code out of revision control and use it in their implementation of __PHYSFS_platformCalcUserDir(). This change let me remove __PHYSFS_platformGetUserName(), too.

Cleaned up some FIXMEs.

Removed a FIXME: use correct error code for writing to read-only archives.

Make sure the prefdir has a final dirsep on it. This matches the behaviour of PHYSFS_getBaseDir() and PHYSFS_getUserDir().

Fixed some brainfarts in the Windows version of PHYSFS_getPrefDir().

Patched to compile on Windows.

PHYSFS_setSaneConfig() now uses PHYSFS_getPrefDir().

Added PHYSFS_getPrefDir().

Removed a FIXME.

Reworked the error reporting API. Now we use error codes instead of strings. This is based on work originally done by Christoph Nelles.

Fixed mutex misuse.

Check for mutex bugs.

Use UTF-16 on Windows, not UCS-2.

Try to make a sane default for CD detection path by platform. This is so this can work even when dropping PhysicsFS into another project without CMake doing header tests and filling in the defines.

Make physfs_platforms.h define with a 1, so "#if X" works. Added a few other pertinent platforms.

Use our platform test macro for Solaris.

Added Linux and Solaris tests.

Let's gamble that everything has assert.h. (and we'll mask out specific platforms if we find one that doesn't.)

Minor code style cleanup in platform_beos.cpp ...

Removed some unused code.

Use physfs_platforms.h in physfs_internal.h, to avoid repeated macro tests.

Removed llseek(). Use Linux's off64_t support instead.

Fixed a comment. Cut and paste error, I guess?

Removed __PHYSFS_platformCvtToDependent(). It's only used by archive_dir.c, and it's trivial to make it into platform-independent code for that one module. Bonus: less malloc() pressure...now every access to the native filesystem doesn't require a temporary heap allocation.

Make __PHYSFS_platformDirSeparator into a single char. This multichar thing was always stupid. Pull it out of revision control if you ever need it.

Removed __PHYSFS_convertToDependent(), as dead code.

Reworked BeOS CD detection code. Cleaned up, removed a malloc(), removed unnecessary BAIL macros.

Added Evgeny Podjachev to the credits.

Fixed PHYSFS_read() and PHYSFS_write() in the dev branch. PHYSFS_read() and PHYSFS_write() should return number of objects written, not object size. Thanks to Evgeny Podjachev for the fix!

Removed check that .zip files are less than 4 gigabytes. This would become a bogus check with zip64 support anyhow, but even here, if you have a .zip that's close to 4 gigabytes, and a self-extracting program prepended to it that pushes it over that limit, this test fails incorrectly.

Fixed dereference of free()'d memory. Thanks to Evgeny Podjachev for the fix!

Apparently, __PHYSFS_platformCurrentDir() is dead code.

Move Windows CD-ROM detection to another thread that uses device notifications. Fixes blocking when a disc is spinning up, except on initial call.

PhysicsFS works on Win64 now.

Fixed stack smashing in newly-aligned __PHYSFS_smallAlloc().

More doc tweaks.
