* Rewrite signal mask decoding without sigset_tDmitry V. Levin2014-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sigset_t provided by libc is not quite convenient. In glibc, sigset_t is an array with space for 1024 bits, which is much more than required: all architectures supported by Linux have only 64 signals except MIPS, which has 128. In bionic libc, LP32 sigset_t is only 4 bytes long, which is less than necessary. With this change, signal mask is decoded without use of intermediate sigset_t structure, which saves us some cpu cycles in case of glibc with its inflated sigset_t, and enables build with libcs where sigset_t is broken. Old implementation used to check each signal number in the given signal mask twice using sigismember(). New implementation is based on popcount and next_set_bit() so it's noticeably faster. * configure.ac: Check for __builtin_popcount. * signal.c: Ensure that NSIG >= 32. (sprintsigmask, sprintsigmask_long, printsigmask): Remove. (popcount32, sprintsigmask_n): New functions. (tprintsigmask_addr, sprintsigmask_val, tprintsigmask_val): New macros. (print_sigset_addr_len, sys_sigsetmask, sys_sigreturn, sys_siggetmask, sys_sigsuspend, sys_sigprocmask, decode_new_sigaction): Update to use new signal mask decoding interface. * tests/sigaction.c (main): Add a test with almost filled signal mask. * tests/sigaction.awk: Update.
* tests: tighten sigaction checkDmitry V. Levin2014-02-08

* tests: rename all tests so that their names end in .test suffixDmitry V. Levin2014-02-02
| | | | | | | | | | | | | | | | | Due to automake limitations, some features work only for tests that end in one of the suffixes listed in TEST_EXTENSIONS. * tests/detach-running: Rename to detach-running.test. * tests/detach-sleeping: Rename to detach-sleeping.test. * tests/detach-stopped: Rename to detach-stopped.test. * tests/net: Rename to net.test. * tests/ptrace_setoptions: Rename to ptrace_setoptions.test. * tests/qual_syscall: Rename to qual_syscall.test. * tests/sigaction.sh: Rename to sigaction.test. * tests/stat: Rename to stat.test. * tests/strace-f: Rename to strace-f.test. * tests/Makefile.am (TESTS): Update.

* tests: add a test for rt_sigaction outputDmitry V. Levin2014-01-08
| | | | | | | | | | | | | | | | Since "struct sigaction" varies between architectures, rt_sigaction decoding sometimes produces incorrect output.

(TESTS): Add sigaction.sh. (EXTRA_DIST): Add sigaction.awk. * tests/.gitignore: Add sigaction.

* tests/stat: enhance regexpsDmitry V. Levin2013-05-06
| | | | | * tests/stat: Enhance regexps that check tracing of stat/stat64 and fstatat/fstatat64 syscalls.
* tests/stat: support fstatat syscall for stat()Chris Metcalf2013-05-06
| | | | | | | | | | | | | | | Newer Linux architectures don't support the stat/stat64 syscalls. Instead they use fstatat() with AT_FDCWD and an extra flags argument. Support seeing this output in the 'strace -efile' test. As part of this change, use "grep -E -x" syntax consistently for all stat tests, since the number of \(foo\)\? expressions was becoming pretty unwieldy. * tests/stat: Update stat/stat64 check regexp to handle architectures that use fstatat instead. Use "grep -E -x" syntax consistently. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
