    • PMPthreads 1.8.9
      1. Bug fix and cleanup. The bug showed up when new file descriptors were created between a fork() and corresponding exec(), then dup2(). After the exec(), the file descriptors got corrupted.

    • RPMs for PMPthreads 1.8.8
      1. Created RPMs for the PMPthread distribution. This should make installing, upgrading and removing versions of PMPthreads easier for those with the RedHat Package Manager installed. The binaries are precompiled for Linux and work with both glibc and libc. They can be found on the PMPthread Download Page.

    • PMPthreads: 1.8.8
      1. incorporated patches for SmartGDB into the PMPthreads source tree
      2. fixed select(): now returns correct number of active file descriptors and sets the proper descriptors active (FD_ISSET). Many thanks to Steve Bernacki Jr. for his finding the bugs and providing a well documented test case!

    • PMPthreads: 1.8.7
      1. added #include to machdep/linux-1.0/__unistd.h to be able to use sysconf() functions in Linux libc
      2. fixed bug in fcntl() in pthreads/fd.c when using F_DUPDF function
      3. fixed spelling of PTHREAD_CANCELED (was PTHREAD_CANCELLED) to match POSIX spec
    • Moved location of PMPthreads distribution to humanfactor.com

    • PMPthreads: 1.8.6
      1. Kevin Street found a bug in the FreeBSD version and provided a fix. He also provided a test case to ensure that other platforms check for the problem. Added this case called test_stack.c to the 'tests' directory. Use 'make check' to test your installation. Thanks Kevin!
      2. Added fd_check_entry to dup2 and table sizecheck to fd_check_entry() patch by Martin Fuchs
      3. Rearranged some pointer arithmetic in stdio/xprintf.c to make more standard/portable.
      4. Set/reset static variables in net/getservent.c
      5. Cleaned up sys/stat.h for Linux to prevent compiler warnings
    • Cheryl Huntington wrote up some information on how the PMPthreads queues work. If you are interested in the internals of the library, this is a great document.
    • Stephane Peter has written a C++ library designed to ease development of multithreaded applications using POSIX-style threads on UNIX systems. I have added a link to the source code.
    • Added 12 additional links to Pthread Links page all in the Miscellaneous category.

  • January 18, 1998

    • Added stuff for using Pthreads and X-Windows. In particular, the use of GTK and Pthreads.
    • Announced GPK, the General Proxy Kit for making the GTK event loop thread act a server for GTK requests for other threads.

  • January 16, 1998

    • New version of PMPthreads: 1.8.5 -- Made to run on Red Hat Linux 5.0
      • jmp_buf struct struct changes
      • machdep system calls to SYS_prev_stat, SYS_prev_lstat and SYS_prev_fstat -> SYS_stat, SYS_lstat, SYS_fstat
      • made "make realclean" really clean up for distribution purposes
      • miscellaneous conditional header file includes
      • added sys/stat.h to make the stat struct match that used in PMPthreads machdep_sys_stat, machdep_sys_fstat, etc. glibc changed this
    • New version of PMPthreads: 1.8.4
      • resolver now looks at the /etc/hosts file before trying to resolve the name with a DNS
      • resolver now handles machines without /etc/resolv.conf files and situations where /etc/resolv.conf does not specify any nameservers
      • now handles multiple nameservers properly -- falls back to use the next if the previous is unavailable
      • changes to gethostbyname.c, res_search.c and res_internal.c

  • November 13, 1997

    1. New version of PMPthreads: 1.8.3

  • October 1-5, 1997

    1. Created shell of basic site
    2. Created first cut of Programming POSIX Threads web pages
    3. Created distribution of Patched MIT Pthreads (pmpthreads) using Monty's version as base. This is pmpthreads version 1.8.0.
    4. Adding additional patches from mailing list to 1.8.0. Incremented version to 1.8.1.

  • October 13, 1997

    1. Added fixes to PMPthreads from Monty for killing threads during read(), write() and select(). Released as version 1.8.2.
    2. Updated DBUG page with licensing and credits information.

  • Current Activities

    1. Discussions about SmartGDB extensions to MIT pthreads for improved debugging support
    2. Filling out pages
    3. Packaging DBUG as its own distribution
    4. Building threaded X-Windows interface using the Gimp's GTK library
