mpatrol

A new --call-graph option in the mprof command, new --gui and --verbose options in the mptrace command (which also displays useful statistics), a fix for a rare bug when displaying the leak table and call graph with call sites which have no associated symbols, new chapters on heap corruption, memory leaks, and porting to the mpatrol manual, and moving the Tools and Utilities sections to the top level.

New additions include the LEAKTABLE option, the
__mp_iterateall() function, the __mp_errno global variable and a
function to obtain the error message string corresponding to an
error code, __mp_init_* and __mp_fini_* initialisation and
finalisation function support. The --sim-file option was added
to the mptrace command, and Dmalloc-compatible function
implementations were added as an external package. The support
for marked allocations was finished. Tru64 is now supported.
The library is now no longer initialised on Linux until the
environment variables are fully set up. A problem building the
shared version of the mpatrol library with some versions of GNU
C++ was fixed.

New __mp_atexit() and __mp_setmark() functions, more fields to the information returned by __mp_info(), and better source-level information when __mp_check() is called. A new FREMRK error, a fix for a problem which prevented const being used when compiling with a C++ compiler, fixes for a problem when profiling memory reallocations and a typing error which would prevent compilation on Windows platforms, and fixes for std namespace problems for set_new_handler() on Windows platforms. HEAPDIFFSTART() and HEAPDIFFEND() were lowercased, and support was added in the heapdiff tool for marked memory allocations. Dbmalloc-compatible function implementations were added as an external package, and the trace file in the mtrace tool is automatically closed at exit.

This release includes libmpalloc to quickly remove
all mpatrol functionality, libmptools which
contains additional tools built on top of the
mpatrol library, and heapdiff, mgauge, and mtrace
packages. In addition, C++ operators are now ANSI
standard conforming, reallocf() has been added,
lots more mpatrol interface functions including
allowing snapshots of the heap and iterate across
allocations, an Automake macro for incorporating
mpatrol into new or existing projects, and
documentation and manual page archives are now
distributed with the main mpatrol distribution.

The MP_MALLOC() family of functions for recording the type name and type size of a memory allocation, the xmalloc() family of functions which never return NULL, a new header file and library for use when mpatrol is not being used, FreeBSD, NetBSD, OpenBSD and SunOS support, the ability to read symbols from a.out files, and the ability to build mpatrol as a shared library on AIX as well as being able to read symbols from shared libraries on AIX have all been added. The COFF and XCOFF symbol readers now require the use of the libld object file access library. The behaviour of the low memory handler has been changed to automatically retry the memory allocation once the handler has been called. mpatrol now stores information about the point of last reallocation rather than the point of original allocation. The manual pages are now also supplied in HTML format.
