Most glibc tests that use mtrace to verify that there were no memory
leaks from the glibc facilities used in a given test depend on the
.out file of the previous test so that the mtrace test runs mtrace and
nothing else.
Two, however, have a single target combining mtrace with something
else. In the case of libio/tst-fopenloc.check, the test both compares
the output with an expected baseline and runs mtrace. In the case of
posix/tst-rxspencer-mem, the test is run (with different command line
from the main run) and then mtrace is run, from the same makefile
target.
This patch splits both of these tests up to use separate makefile
targets for each thing tested; in the tst-rxspencer case, a file
tst-rxspencer-no-utf8.c is created that just includes tst-rxspencer.c,
as is usual for tests where the same code gets tested in different
compile-time or runtime configurations.
Adding $(evaluate-test) to test commands, as in
<https://sourceware.org/ml/libc-alpha/2014-01/msg00194.html>, will no
longer need to insert && between multiple commands, as all tests will
either have just a single command or already use &&.
Tested x86_64.
* libio/Makefile ($(objpfx)tst-fopenloc.check): Split into
separate $(objpfx)tst-fopenloc-cmp.out and
$(objpfx)tst-fopenloc-mem.out targets.
(tests): Update dependencies.
* posix/Makefile (tests variable): Add tst-rxspencer-no-utf8.
(generated): Change tst-rxspencer-mem and tst-rxspencer.mtrace to
tst-rxspencer-no-utf8-mem and tst-rxspencer-no-utf8.mtrace.
(tst-rxspencer-no-utf8-ARGS): New variable.
(tst-rxspencer-no-utf8-ENV): Likewise.
(tests target): Depend on $(objpfx)tst-rxspencer-no-utf8-mem
instead of $(objpfx)tst-rxspencer-mem.
($(objpfx)tst-rxspencer-mem): Change target to
$(objpfx)tst-rxspencer-no-utf8-mem. Depend on
$(objpfx)tst-rxspencer-no-utf8.out instead of running test program.
* posix/tst-rxspencer-no-utf8.c: New file.
This helps testing for regression of BZ#15339. Creation of network
isolated environments is a privileged operation and therefore is not
included to the test.
Fixes BZ #12723
The variable pipe buffer size does nothing to the value of PIPE_BUF,
since the number of bytes that are atomically written is still
PIPE_BUF on Linux.
* posix/regex_internal.c (re_string_skip_chars): Fix miscomputation
of remain_len that may cause incomplete multi-byte character and
false match.
* posix/bug-regex33.c: New file.
* posix/Makefile (tests): Add bug-regex33.
This is another bug in computing the fastmap. It was reported by a user
of sed because it usually does not happen with !_LIBC. However, it is
there in that case too.
The bug is that whenever we have a range at the beginning of the regex,
the regex must be tested on any possible multibyte character. The reason
why _LIBC masks it, is that in general there is a collation symbol for
each possible multibyte-character lead byte, so all the lead bytes are
in general already part of the fastmap.
The tests use cyrillic characters as an example. With _LIBC, they pass
without the patch too, but you can make them fail by removing collation
symbols handling.
* posix/Makefile ($(inst_libexecdir)/getconf): Make hard links to
$(inst_bindir)/getconf if possible.
* posix/Makefile ($(objpfx)getconf.speclist): New target.
(generated): Add it.
($(inst_libexecdir)/getconf): Use it.
(tests): Add tst-cpucount.
* posix/sched_cpucount.c: New file.
* posix/tst-cpucount.c: New file.
* posix/Versions: Export __sched_cpucount with version GLIBC_2.6.
(fnmatch): Pass NULL as last argument to internal_fn{,w}match.
* posix/fnmatch_loop.c (struct STRUCT): New type.
(FCT): Add ends argument. If ends != NULL and normal * is
seen in the pattern, store current pattern and string pointers
and return. Adjust recursive calls.
(EXT): Adjust FCT callers.
(STRUCT): Undef at the end of the file.
* posix/Makefile (tests): Add tst-fnmatch2.
* posix/tst-fnmatch2.c: New test.
