* Do not suppress signal delivery messages with -qqDmitry V. Levin2013-05-28
| | | | | | | | | | | Current implementation of -qq does not allow suppressing exit status messages without suppressing signal delivery messages, which is not good. There is a traditional "-e signal=none" syntax that can be used to suppress all signal delivery messages. This partially reverts commit v4.7-222-g01997cf. * strace.c (trace): Do not suppress signal delivery messages with -qq. * strace.1: Update documentation about -qq option.
* Allow -q to be repeated for very quiet outputDaniel P. Berrange2013-05-13
| | | | | | | | | | | | | | Even with the -q flag specified, tracing output is still mixed with messages about signals and process exit status, which is often irrelevant. Allow the -q option to be repeated to force the suppression of signals / exit status info too. * defs.h: Change 'qflag' from 'bool' to 'unsigned int'. * strace.1: Document ability to repeat '-q' option. * strace.c: Allow '-q' to be repeated to quieten process exit status and signal messages.

* Use dynamically-sized selected[] array for -P PATHDenys Vlasenko2013-03-05
| | | | | | | | | | | While at it, added a small optimization of not remembering the path twice if it happens to be the same. text data bss dec hex filename 245111 680 10860 256651 3ea8b strace_old 245075 680 9804 255559 3e647 strace Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* Make -b take SYSCALL param, document it in --help and in manpage.Denys Vlasenko2013-02-27
| | | | | | | | | | | | To not waste an option letter for just one trick, extend -b to take a parameter: "on which syscalls do you want to detach?". Currently supports only execve. While at it, fixed (by removing non-Linux and stale info) and extended manpage text about -f. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* manpage: remove bugs which are fixedDenys Vlasenko2012-03-15
| | | | | | | | | | | | | | "A traced process ignores SIGSTOP" - fixed, expected to be in linux-3.4.x. "A traced process which tries to block SIGTRAP will be sent a SIGSTOP in an attempt to force continuation of tracing." - not needed and no longer done. "On Linux, exciting as it would be, tracing the init process is forbidden" - not true anymore. "When a traced process receives a SIGTRAP signal not associated with tracing, strace will not report that signal correctly." - not true anymore.
