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
For the 96/03/09 release version 1_60_beta5
Ports
Sparc running NetBSD-1.1
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/engine-sparc-sunos-5.3.c : Fix machdep_sys_select() to return
machdep_sys_poll() errors and not the number of entries found.
gen/getcwd.c : Use strlen(dp->d_name) not dp->d_namlen because there
may be extra data associated with dp->d_namelen.
machdep/freebsd-2.0/__unistd.h: Change #define _POSIX_VDISABLE to 0xff
include/pthread.h : Added prototypes pthread_kill(), pthread_signal()
machdep/linux-1.0/__signal.h : Added #define __sigmask() and
#define sigmask, and fixed other SIG macros to use __sigmask.
machdep/linux-1.0/dirent.h : #include <sys/types.h>
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
shouldn't be inlined.
machdep/sunos-4.1.3/stat.h : Added __BEGIN_DECLS and __END_DECLS.
machdep/alpha-osf1/cdefs.h, machdep/hpux-9.03/cdefs.h
machdep/linux-1.0/cdefs.h, machdep/sunos-4.1.3/cdefs.h
machdep/sunos-5.3/cdefs.h, machdep/ultrix-4.2/cdefs.h :
#define __INLINE static inline and don't #define
__CAN_DO_EXTERN_INLINE if __cplusplus and __GCC__ is defined.
pthreads/fd_sysv.c : Fix so that only systems without socket systemcalls
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.

A solaris port from me.
