__|_(_)_____|______________________________________________________
Changes between 1.2.0 and 1.2.1 (26-Jul-2000 to 28-Jul-2002)
*) Fixed the package rolling: configure.ac was missing because
of a bug in devtool.conf.
[Kean Johnston <jkj@armory.com>]
Changes between 1.1.3 and 1.2.0 (01-Jul-2000 to 26-Jul-2002)
*) Fixed race condition in temporary file creation.
[Sebastian Krahmer, SuSE Security]
*) Make sure that under MM_SEMT_IPCSEM (mutex implementation method is
SysV IPC semget) the {mm,MM}_permission() also changes the owner of
the semaphore.
[Jonathan Kamens <jonathank@worldwinner.com>]
*) Add support for IRIX 6.5 and other Unix flavors which have
MAXPATHLEN in <sys/param.h>
[Joe Orton <jorton@redhat.com>]
*) Removed the old fbtool stuff for reporting the success/failure
because after 3 years of existence we really know that OSSP mm
works on every reasonable Unix flavor on this earth.
[Ralf S. Engelschall]
*) Upgraded to GNU autoconf 2.53, GNU libtool 1.4.2 and GNU shtool
1.6.1 build environment (using OSSP devtool).
[Ralf S. Engelschall]
*) Changed home from http://www.engelschall.com/sw/mm/ to OSSP
http://www.ossp.org/pkg/lib/mm/ and official name from "MM" to
"OSSP mm" to follow name conventions in the OSSP project.
[Ralf S. Engelschall]
*) Removed variables from ANSI C function prototypes in mm.h
to avoid any potential conflicts in advance.
[Ralf S. Engelschall]
*) Adjusted year in copyright messages for 2002.
[Ralf S. Engelschall]
*) From Apache 2.0's MM patch set:
Make Autoconf test for maximum shared memory size support BEOS and
make decision cacheable.
[The Apache Software Foundation]
*) Fixed initializations of fdxxx variables in mm_core.c
[Alexander Farber <farber@cpan.org>]
*) Added $(DESTDIR) support to Makefile.in. This makes life easier
for RPM package building.
[Brad <brad@openbsd.org>, Ralf S. Engelschall]
*) Fixed typo in mm.h: (still unused) definition of SIZEOF_mem_core_fd
lacked a closing parenthesis.
[Alexander Farber <farber@cpan.org>]
*) Added required "(void *)" cast to MAP_FAILED in Autoconf stuff.
[Albert Chin-A-Young <china@thewrittenword.com>,
Joe Orton <jorton@redhat.com>]
Changes between 1.1.2 and 1.1.3 (21-May-2000 to 01-Jul-2000)
*) Upgraded to GNU libtool from version 1.3.4 to 1.3.5
and upgraded GNU shtool from version 1.4.9 to 1.5.0
[Ralf S. Engelschall]
*) Added OS/390 support to config.sub.
[Greg Ames <gregames@raleigh.ibm.com>]
*) Fixed type-warnings related to `char' vs. `unsigned char' in mm_test.c
[Ralf S. Engelschall]
*) Let the internal mm_insert_chunk() function detect the situation
where a chunk of memory is inserted twice (usually caused by the
application through multiple and this way illegal calls to mm_free() with
the same argument). This especially makes sure the internal list
of free chunks is not corrupted.
[Jeffrey Hsu <hsu@FreeBSD.ORG>, Ralf S. Engelschall]
*) Fixed typos in mm.pod.
[Ralf S. Engelschall]
Changes between 1.1.1 and 1.1.2 (30-Apr-2000 to 21-May-2000)
*) Fixed some logic in mm's configuration that removes -g from CFLAGS.
It incorrectly collapsed " -g " to "", which leaded to invalid CFLAGS.
[Jeff Trawick <trawickj@bellsouth.net>]
*) Fixed shared memory decisions on Linux:
We now avoid using MM_SHMT_MMANON (seems to be completely
broken on 2.0), MM_SHMT_MMZERO (seems like Linux 2.0 hates this
classical combination and return EINVAL for unknown reasons) and
MM_SHMT_IPCSHM (requires that a IPC shm filesystem is mounted
since 2.3). So, technically MM_SHMT_IPCSHM is preferred if the shm
filesystem exists, else we count on MM_SHMT_MMFILE now.
[Ralf S. Engelschall]
Changes between 1.1.0 and 1.1.1 (30-Apr-2000 to 30-Apr-2000)
*) Fixed compilation under Solaris where the SunOS4 and BS2000 kludges
for <sys/shm.h> conflicted with the Sun vendor includes (which
unfortunately use the defines).
[Ralf S. Engelschall, Jeff Beard <jeff@cyberxape.com>]
Changes between 1.0.12 and 1.1.0 (28-Sep-1999 to 30-Apr-2000)
*) Fixed `make test' feedback procedure in Makefile.in now that the
platform list is stored in the PORTING file.
[Ralf S. Engelschall]
*) Renamed file CHANGES to ChangeLog.
[Ralf S. Engelschall]
*) Fixed pointer arithmentic in memset/memcpy replacements
by casting `void *' arguments to `char *'.
[Sascha Schumann <sascha@schumann.cx>]
*) Added BS2000 support for <sys/shm.h> stuff.
[Martin Kraemer <martin.kraemer@mch.sni.de>]
*) Added an include for <fcntl.h> to maximum shared mem segment size
check in aclocal.m4. This especially fixes compile problems under for
Solaris 8.
[Alexander Demenchuk <alder@untech.com>, Greg Gears <gears@netair.com>]
*) Fixed a warning under IRIX related to size_t comparisons
[Ralf S. Engelschall]
*) Added support for IBM OS/390
[Jeff Trawick <trawick@ibm.net>]
*) Upgraded to GNU libtool from version 1.3.3 to 1.3.4
and upgraded GNU shtool from version 1.4.6 to 1.4.9
[Ralf S. Engelschall]
*) Upgraded config.guess to GNU Pth's version and
use "/sbin/sysctl" under FreeBSD instead of just "sysctl"
[Jeff Trawick <trawick@ibm.net>]
*) Added platform support for the esoteric Unix look-alike BeOS
[David Reid" <dreid@jetnet.co.uk>]
*) Added `make check' as an alias for `make test'
[Ralf S. Engelschall]
*) Adjusted copyright messages for year 2000
[Ralf S. Engelschall]
*) Fixed Autoconf checks for SunOS
[Ralf S. Engelschall]
*) Fixed a bug in aclocal.m4's AC_CHECK_DEFINE macro.
[Ralf S. Engelschall]
*) Updated the manual page (typos, fixes, etc.)
[Ralf S. Engelschall]
