New tool lmdbg-head(1) was implemented, see the man page for
details.
README: recomendations for procfs
lmdbg-sym:
- Much simplier (and correct) method for address convertion was
implemented. As a result lmdbg-sym works correctly on AltLinux
where ASLR and PIE are enabled by default.
- Breakpoint are removed very soon after creation.
This saves a lot of memory consumed by gdb(1)
and dramatically speeds up it.
lmdbg-run:
- Arguments are passed correctly to progname
- On glibc-based systems (e.g. Linux) malloc hooks are not used
anymore as they are declared deprecated
- Addresses from lmdbg.c are not included to stacktrace
- Additional checks for address (returned by stacktrace(3))
correctness. As a result gdb(1) doesn't crash and therefore
lmdbg-sym(1) work correctly.
- stacktrace(3) doesn't not crash anymore on NetBSD/x64_64 with
system utilities. See implementation details in stacktrace.c.
- New option -N
- Option -v works correctly with non-zero exit status of progname.
- Exits with error if progname is not specified.
lmdbg-stat:
- Fix for NULL dereference appeared if free(3) or realloc(3)
stacktrace is seen without appropriate malloc(3) stacktrace.
AWK interpreter is found at configure time via MKC_REQUIRE_PROGS.
Build and regression tests were fixed for non-empty MAKEOBJDIR case.
ChangeLog file is never installed.
lmdbg-s2m and lmsbg-m2s was moved to libexec dir.
mk-configure >= 0.24.0 is required for build.
Fixes, improvements and additions in regression tests.
