[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] *) Splitted README into README, PORTING and THANKS document. [Ralf S. Engelschall] _ ___ / | / _ \ | || | | | | || |_| | __|_(_)___/________________________________________________________ Changes between 1.0.11 and 1.0.12 (06-Sep-1999 to 28-Sep-1999) *) Recreated configure with latest Autoconf 2.13.1 (snapshot) *) Always use --mode=xxx for libtool calls to avoid problems under situations where $CC doesn't allow libtool to guess the mode correctly.
