Dear All,
I like to propose a change to strace version 4.15 that re-enacts the currently
hidden -z option for output filtering ("print successful syscalls only").
Please find attached a patch file against 4.15 release that implements a
staging approach, i.e. builds output in memory but prints successful syscalls
only when the -z option was given on the cmdline. The implementation is based
on the STDIO library function open_memstream(); since it might not be available
all every target system, respective code sections were guarded with "#ifdef
_GNU_SOURCE" directives. To apply the patchfile:
cd strace-4.15
patch -p1 <strace-4.15i1.patch
Note 1: Since the syserror macro (defined in defs.h) does not distinguish
between failed and not-returned, the "exit_group()" syscall will be filtered as
well with -z.
Note 2: automake would not run on my system, therefore the patch has both
Makefile.in and Makefile.am. The latter was not tested.
Best regards,
Burkhard Kohl
