2005-06-05: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - libc:
        o the setitimer backend was making incorrect assumptions about the
          HTIMER range - NULLHANDLE is valid for HTIMER. Changed it to use ~0U
          as invalid handle. (untested)
        o Default TCPIP mode is __USB_LIBC_TCPIP. When either TCPV40HDRS or TCPV41HDRS
          are defined we are in strict mode and __USB_LIBC_TCPIP will not be defined.
    - libomflib, emxomfar:
        o Allow multiple modules by the same basename. This is not in tradition with
          other librarians, but it solves incompatible behaviour between emxomfar and ar.
    - ld:
        o Avoid using alloca since we might easily run out of stack for big objects
          with debuginfo.
    - emxomf:
        o Added support for new EMX a.out stab N_EXP (0x6c). This encodes export
          definitions. (gcc can do __declspec(dllexport) now.)
          TODO: ld needs updating, probably this is the right time to drop the
                old ld and fixup the binutils port!

2005-05-08: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - libc:
        o Added _getenv_[int|long|longlong]. Using this for LIBC_THREAD_MIN_STACK_SIZE.
        o Ported the BSD SysV Semaphore module.
        o Added a signal notification callback to the thread structure.
        o Changed tcpip term callback to more generic exitlist callback (SPM).
        o Ported the BSD SysV Shared Memory module.

2005-05-05: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - libc:
        o Added fts.h and ported the BSD implementation.
          It's not 100% correct since we're lacking fchdir and cannot open
          directories - will update it when this is in place.
        o Disabled the UF_ and SF_ defines in sys/stat.h since we don't have st_flags.
        o Added mkfifo (stub).
        o Added lutimes and futimes, replacing __utimes.

2005-05-01: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - libc:
        o Fixed incorrect d_type returned by readdir and readdir_r.
        o Changed chdir() to unix style, added _chdir_os2() as a backwards compatible
          api. _chdir2() and chdir() are operating identically now.
        o Fixed several incorrect/incomplete path resolve cases. Some causing
          invalid ino values.
        o Unlock the libc DLL before installing it (cp, make or someone might be using it).
        o Unix root rewrite rule ends it's pszTo with a slash, this caused
          two slashes and thus UNC trouble.
        o Quick rewrite of access() (also affects eaccess()) to work in chroot environment.
        o Added O_BINARY to all opens in bsd/db.

2005-04-30: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - libmoddef:
        o Allow empty definition strings. (weakld failed on python _curses_m)
    - weakld:
        o Fixed incorrect .def-file parse error message.
    - sys/param.h:
        o Added MAXBSIZE, BKVASIZE and BKVAMASK which are used by some BSD tools.
    - libc:
        o Added fchmod and reimplemented chmod and lchmod. Still missing FS level
          unix attribute handling, but this is a start.

2005-04-25: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - libc:
        o Added the sysctl interface from BSD. Not all values are
          supported, nor are we compatible with tcpip41 sysctl yet.

2005-04-24: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - libc:
        o Fixed bug in getfsstate(). (df from coreutils works now!)
        o Implemented process priority management. Added nice(), setpriority()
          and getpriority() in the process.
        o Added process enumeration and access function to sharedpm.

2005-04-23: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - emxomf:
        o Refined the 'G' hack fixing globals in the text segment.
    - libc:
        o Added cs:eip to the abnormal termination message. (signals.c)
        o Default stack size 512KB when caller specifies 0. (beginthr.c)
        o Use the env.var. LIBC_THREAD_MIN_STACK_SIZE value as a byte count
          specifying the minimum stack size. When not specified minium size
          defaults to 4096. (beginthr.c)
        o Added the libsocket and libsyslog libraries to the libc IMPORT library.
          There are now two sets of libc_dll.a/lib libraries, one for tcpipv4 and
          one for tcpipv41+ (default).
        o Added nanosleep() and changed usleep() and sleep() to use it.
        o Added wmemcpy(), wmemset(), wmemcmp(), wmemchr() and wmemmove(). (untested)
        o Added SUN/HP/RTLinux api gethrtime() as a wrapper around the DosTmr* apis.
        o Rewrote atexit() fixing problem with the callbacks calling exit() recursivly
          and adding on_exit().
        o Added stdio_ext.h and implemented __fpending() and __fbufsize().
          (Just to make coreutils easier to port.)

2005-03-23: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - src/lib/sys/__spawnve.c:
        o Fixed double free of pFS (should've been pSig).
          Thanks for froloff.

2005-03-19: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - 386/builtin.h:
        o Fixed serveral bugs in the atomic inc/dec functions.
          Added a testcase for these.
    - libc:
        o Fixed various typos in the socket per process counting. Thanks to
          nickk for point these out.

2005-03-13: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - version.smak:
        o 6b4 -> 6b5.

    - libc:
        o Implemented socket duplication.
        o Fixed various socket close & fork bugs.
        o Applied parts of tcpipver patches from Lorne and Froloff.
        o Fixed various UNC trouble reported by David.
        o Fixed open problem in DosEx.
        o Fixed incorrect pool allocation in DosEx.
        o Fixed missing free pool item in DoxEx - *big* leak.
        o Fixed TID/PID mixup when calling DosVerifyPidTid() from fmutex wait loop.
        o Applied patch from Nickk for broken settimeofday().
        o Moved iconv into LIBC.
        o Ported GLIBC intl and made it a part of LIBC.
        o Implemented -Zargs-wild and -Zargs-resp crt0 variations.
        o Added support for single quoted arguments. (pray this doesn't screw up...)
        o Replaced the __atod implementation with the NETLIB gdtoa implementation
          used by BSD. (The old routine kept hitting assertions.)
        o Created libc06a4 forwarder dll.

    - libiconv, libdl, libm:
        o Made these empty stub libraries.

    - emxomf:
        o Fixed getopt(,,"l::") problem. BSD getopt doesn't pass FLAG_PERMUTE for getopt and
          thus it would consume the next argument unless it was an option. Using
          getopt_long(,,"l::", NULL, NULL) solves the problem.

    - testcases:
        o Testcases for various new problems/code.

2005-02-01: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - libc:
        o Fixed bogus bubble sort in setlocale/LC_COLLATE.

2005-01-31: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - libc:
        o Applied readdir_r() errno fix from Lorne.
        o Fixed lstat() backend on request from Lorne.

2005-01-30: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - libc:
        o Applies setlocale patch from Lorne which fixes two bugs in LC_COLLATE.

2005-01-28: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - libc:
        o Applied setlocale patch from Lorne.
        o Faked the C99 lconv additions by copying the local ones.

2005-01-16: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - libos2:
        o Added SafeDosStartSession from Dmitry Froloff.
    - libc:
        o Fixed year problem in settimeofday.
        o Check if fxsave/fxrstor is supported before using them in fork().
          ASSUMES cpuid eax=1 works on all targets.
        o Implemented nl_langinfo(CODESET).
        o Added bunch a of ASCII codeset name conversions.
        o Fixed bug in socket inherit over exec/spawn. Thanks to Froloff.
        o Forgot to take the signal semaphore when receiving a signal
          from the 16bit handler. Thanks to Froloff.
        o rmdir errno fix from Lorne.
        o rmdir shall fail on symlink.
        o rmdir shall return ENOTDIR if the path isn't a directory (but exists).
        o Fixed setlocale(LC_ALL/LC_MONETARY, "C").
        o Changed the process reaper to use internal signal api to skip some overhead.
        o Fixed a return path from signal raise where the signal sem wasn't
          released. (The out of queue node hang.)
    - libsocket:
        o os2_select: Fixed a couple of filehandle conversion bugs. Thanks to Froloff.
        o soclose shouldn't return EBADF but ENOSOCK according to the specs.
    - libsocket, libc:
        o Return ENOSOCK instead of ENOSYS when attempting socket operation on filehandle.


2005-01-??: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - libc:
        o Fixed problem with fork'ed children beliving they were
          still forking after fork() returned. (DLL load issue)
        o Fixed signal queue node leak. Thanks to Lorne.

2004-12-20: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - libc:
        o Added inode and dev calculation for fstat and stat.
          TODO: save unix EAs. opendir d_fileno?
        o Ported all string/w* functions from FreeBSD except wcsxfrm.c.

2004-12-12: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - os2emx.h:
        o Corrected define of NP_NBLK. (thanks to froloff)
    - __mcount:
        o Export stub in all builds but the profiling build.
    - libdl:
        o Removed and stubbed it (install). It's all in LIBC now.
          TODO: make libm and libdl stubbing in LIBC!

2004-12-09: knut st. osmundsen <bird-gccos2-spam@anduin.net>
    - waitpid(), waitid(), wait(), wait4(), wait3(),
      __libc_Back_processWait():
        o Fixed missing WNOHANG handling.
          Created waitpid-1.c testcase in testcase/misc for this problem.
        o Clearified error codes ECHILD and EINVAL, use the waitpid() specs.

    - ChangeLog.Libc:
        o Created this file.
