- For patches made to this release, check the file Changes-mysql
- For the 96/11/11 release version 1_60_beta6
- Ports
- Alpha running NetBSD-1.1 by Chris G Demetriou <cgd+@cs.cmu.edu>
- i386 running BSDi-2.1 by David J MacKenzie <djm@va.pubnix.com>
- Bug Fixes
- Test for struct timespec under linux and DTRT.
- include/unistd.h : #define SEEK_SET, SEEK_CUR, and SEEK_END.
- Bug reported by Stephen Tether <tether@MITLNS.MIT.EDU>
- stdlib/system.c : Uses the POSIX signal systemcalls.
- Bug reported by Matthew Newhook <matthew@thor.udc.neweast.ca>.
- net/gethostbyname.c: #include <string.h> and fix dereference problem.
- Bug reported by Chris G Demetriou <cgd+@cs.cmu.edu>
- pthreads/fd.c: Fix bug in close() reported by
- Bug reported by "William S. Lear" <rael@dejanews.com>
- tests/p_bench_pthread_create.c : Only try and create 10000 threads.
- include/pthread/sleep.h : No need to prototype machdep_gettimeofday()
- since it is declared here.
- Bug reported by Stewart Gebbie <stewart@global.co.za>
- stdio/fwrite.c: Fixed bug where if total bytes written = 0 then a divid
- by 0 occurs. Thanks to CTLarsen@lbl.gov for finding is and to
- Jin Guojun <jin@george.lbl.gov> for submitting a patch for it.
- stdio/refill.c (__swalk_lflush()): Second pass of flush should call
- flockfile() not ftrylockfile(). Just like in __swalk_sflush()
- net/res_internal.c (_res_parse_answer()): It looks like if
- iquery is true and type == T_PTR then the result->h_name
- will be over written because the bp isn't incrementd
- appropriately. Thanks to David Halls <David.Halls@cl.cam.ac.uk>
- for finding it.
- net/serv_internal.c (_serv_buf()) : Allocate more than four bytes
- of buffer space. Reported by drh@@tobit.vnet.net.
- pthreads/fd_kern.c: Make sure exception fds are included in
- machdep_sys_select() for support of select(). Thanks to
- Larry V. Streepy, Jr. <streepy@healthcare.com> for the patches.
- pthreads/fd_kern.c: Fix more I/O routines to report NOTOK on error
- instead of the old -error number. Hopefully this is the last of
- them. Thanks to Larry V. Streepy, Jr. <streepy@healthcare.com> for
- the patches.
- machdep/engine-i386-linux-1.0.c: Remove unneeded machdep_sys_readv()
- and machdep_sys_writev() routines. Reported by
- pthreads/process.c : Fix execl() and execle() to work on sparc systems.
- pthreads/fd_sysv.c : Fix accept() to work under Solaris 2.4

- Additions
- New reentrant netdb similar to Solaris API (ghudson)
- Bug Fixes
- Make default signal handlers work.
- Deadlock scheduling bug reported by Cathy Abbott <cabbot@cs.utk.edu>
- See pthreads-bugs transaction 31
- pthread/queue.c (pthread_queue_remove()): Don't set thread->queue and
- thread->next to NULL unless the thread is removed from the queue.
- pthreads/fd.c (setsockopt(), getsockopt(), getsockname(),
- getpeername()) : Call fd_lock() with appropriate paramaters.
- pthreads/fd_kern.c (sendmsg_timedwait()): Call fd_unlock() with
- FD_WRITE instead of FD_READ paramater.
- machdep/*/timers.h net/res_send.c, pthreads/cond.c, pthreads/select.c
- pthreads/sleep.c, tests/test_pthread_cond_timedwait.c:
- Change timespec to be POSIX compliant.
- include/unistd.h : Change u_int to unsigned [int] in prototypes.
- pthreads/fd.c : Use FD_SETSIZE instead of 1024 for a limit on fds.
- For the 95/09/xx release version 1_60_beta4
- Ports
- SGI running IRIX-5.3
- Additions
- Added pthread_sigprocmask().
- Added CV attributes
- strtok() and strtok_r() (Greg Hudson)
- getsockname() (Sean Levy)
- Bug Fixes
- stdio/fwalk.c, stdio/refill.c : Use flockfile() instead of
- ftrylockfile()/pthread_yield(), for traversing FILE list.
- pthreads/sig.c : Remove enum pthread_sig_flags and just use the vector.
- Added pthread_sigprocmask().
- pthreads/signal.c : Protect calls to pthread_sig_process().
- configure : Create the obj directory.
- tests/test_preemption_float.c : Rewritten to actually work.
- machdep/engine-i386-linux-1.0.c : Added __strtol_internal()
- tests/test_stdio_1.c : Don't use base_name or dir_name as variables.
- gen/getcwd.c : fstat => machdep_sys_fstat, since kernel fd's are
- used in the DIR data structure
- gen/isatty.c : Fixed call to fd_lock() to pass the right # args.
- pthreads/pthread_init.c : Fixed uninitialized members of
- pthread_initial.
-
- For the 95/06/xx release version 1_60_beta3
- Additions
- Add exec variants execl, execlp, execv, execvp (Ken Raeburn)
- pthreads/fd_sysv.c : Added routines setsockopt() and getsockname().
- Added include/endian.h : For machine dependent endian junk. (YUCK)
- Added socketpair()
- Added ttyname_r()
- Bug Fixes
- config/Makefile.in : Need $$ to reference shell variables in make.
- config/configure, config/configure.in : Redo freebsd2.* machine.
- machdep/sunos-4.1.3/__stdlib.h : typedef pthread_size_t size_t
- pthreads/fd.c : Fix bug with fd_free(), dup(), dup2(), and close()
- where a fd gets lost after a dup() then close().
- pthreads/fd_kern.c : The fd_table[fd]->flags of the fd that accept()
- returns should be the same as those of the fd passed to accept().
- stdio/fclose.c : Don't call funlockfile(fp) after fp->_file has been
- closed.
- pthreads/select.c : Move pthread_sched_prevent() inside the statement.
- if (machdep_sys_select(...) == OK)
- pthreads/machdep/linux-1.0/cdefs.h : moved the include_next outside
- of the ifdef so that it would eventually find the system cdefs.h
- pthreads/signal.c : Check sig_to_process before and after fd_kern_wait()
- . It is possible for sig_handler_fake() to registered one.
- pthreads/signal.c : Unset pthread_run temporarily around the call to
- sig_handler(0). places where this causes core dumps should check
- pthread_run.
- include/stdlib.h : Fix prototype for bsearch().
- machdep/syscall-i386-freebsd-2.0.S syscall-template-i386-freebsd2.0.S:
- Fix macro expansion problems for FreeBSD-2.0

- machdep_sys_poll() errors and not the number of entries found.

- machdep/linux-1.0/wait.h : Fix #define WIFSTOPPED(x) to use __WSTATUS(x)
- machdep/syscall-i386-linux-1.0.S : Added elf support. (NOT TESTED)
- pthreads/stat.c : Added to separate linux stat calls.
- (SGI will need this too)
- pthreads/signal.c : Whereever #ifdef (SA_RESETHAND) is used then
- #ifdef (SA_RESTART) also
- gen/isatty.c : isatty_basic() is called with the KFD not UFD.
- machdep/sunos-4.1.3/__stdlib.h : #include <sys/stdtypes.h>
- config/sun4os4.mk : Added pipe to SYSCALL_EXCEPTIONS
- machdep/syscall-sparc-sunos-4.1.3.S : Add machdep_sys_pipe().
- include/stdio.h : Remove __getc() and __putc(), because they really

- compile this file.
- machdep/engine-i386-linux-1.0.c : Fix linux machdep_sys_getdirentries()
- pthreads/gen : Nuke the signal-blocking code in pclose(). It doesn't do
- any good in a threaded program; some other thread would just get
- the signal.
