libstacktrace:
Remove signal handlers and other garbage.
All we need is __builtin_frame_address and __builtin_return_address
builtins and nothing else.
Documentation files have been moved to subproject "doc".
Run "mkcmake install-doc" for installing it (or change SUBPRJ_DFLT).
Only backtrace(3) in libc is accepted as an external implementation
of stacktrace(3). This may fix build failure on FreeBSD with
installed libexeinfo.
Long options have been removed from all programs.
Use standard single-letter POSIX-compatible options.
lmdbg-sym:
- Doesn't accept progname as an argument anymore.
Use -P option instead.
- option --with-so was replaced with -s.
SORRY FOR INCOMPATIBILITIES WITH PREVIOUS RELEASES.
----------------------------------
lmdbg:
- -M option was added. lmdbg(1) is now a meta tools which is able
to not only collecting memory leaks. See the manual page for
details.
- -n option was added
- -T and -B options were added
- Regression tests were added for -M
A lot of improvements and grammar fixes in manual pages.
Thanks to Nikolai Krot for this.
lmdbg-stat, tests/test.sh:
- Fixes for Solaris
lmdbg-run:
- options -T and -B were added to lmdbg-run.
- option -n was added. It disables logging on startup.
Sending SIGUSR1 signal to the process enables it.
-f option was added, synonym for -p.
lmdbg-grep.1:
- documentation for "bytes" variable
If set, LMDBG_MODULES_AWK and LMDBG_STRIP_AWK environment variables
are used as a path to AWK interpreter by "lmdbg-modules" and
"lmdbg-strip" programs respectively.
More regression tests
of malloc/realloc/memalign/free etc. function calls. Unlike many
others, LMDBG does not provide any way to detect overruns of the
boundaries of malloc() memory allocations, as this is not the
goal. Like most other malloc debuggers, LMDBG allows detecting memory
leaks. Unlike some others LMDBG generates full stacktraces and
separates the logging process from analysis, thus allowing you to
analyze application on a per-module basis. Simple but powerful tools
for analisis are also provided.
lmdbg-run - Creates malloc/realloc/free/memalign/... logs
lmdbg-sym - Converts addresses to 'file.c:NUM func_name'
lmdbg-leak - Checks for memory leaks
lmdbg-stat - Gathers statistical information about memory allocations
lmdbg-grep - Greps the stackframes
lmdbg-strip - Strips the stackframes
lmdbg-module - Enrichs the stackframes with a module name
lmdbg-sort - Sorts the stackframes by e.g. total allocated bytes,
a number of memory allocations etc.
lmdbg-sysleaks - Filters out system memory leaks e.g. libc's
