* Complete _BSD_SOURCE / _SVID_source followup cleanup.Joseph Myers2014-02-214-17/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch completes the headers cleanup consequent on removal of _BSD_SOURCE and _SVID_SOURCE (apart from any subsequent deprecations): * #endif conditionals that referred to BSD or SVID are updated. * Redundant __USE_* tests in cases involving __USE_MISC are removed. This includes cases such as __USE_MISC || __USE_ISOC99, where __USE_MISC is redundant (because __USE_MISC is only ever defined in the default / _DEFAULT_SOURCE / _GNU_SOURCE case, when __USE_ISOC99 is also defined; the same applies to the non-XSI-extended POSIX versions), and cases involving __USE_GNU, where __USE_GNU is redundant (because if __USE_GNU is defined, so are the other __USE_* macros). There may well be other cases of __USE_FOO || __USE_BAR tests that could be simplified because one macro implies the other; this patch only addresses cases involving __USE_MISC.

* Split up rules for tests using mtrace and something else.Joseph Myers2014-02-141-7/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Clean up trivially redundant __USE_MISC conditionals.Joseph Myers2014-02-131-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up cases of __USE_MISC that are trivially redundant after the recent substitution of __USE_MISC for __USE_BSD and __USE_SVID: either in constructs such as "defined __USE_MISC || defined __USE_MISC", or else (in the bits/mman.h case) a conditional on __USE_MISC nested inside another __USE_MISC conditional. (The cleanups remaining after this patch are still quite large, but it seems a reasonable piece to separate out.) Tested x86_64. * bits/mman.h [__USE_MISC]: Remove redundant conditionals. * ctype/ctype.h [__USE_MISC]: Likewise. * dirent/dirent.h [__USE_MISC]: Likewise. * grp/grp.h [__USE_MISC]: Likewise. * io/fcntl.h [__USE_MISC]: Likewise. * io/sys/stat.h [__USE_MISC]: Likewise. * libio/stdio.h [__USE_MISC]: Likewise. * posix/unistd.h [__USE_MISC]: Likewise. * pwd/pwd.h [__USE_MISC]: Likewise. * stdlib.h [__USE_MISC]: Likewise. * string/bits/string2.h [__USE_MISC]: Likewise. * string/string.h [__USE_MISC]: Likewise. * time/time.h [__USE_MISC]: Likewise.
* Combine __USE_BSD and __USE_SVID into __USE_MISC.Joseph Myers2014-02-123-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up following the obsoletion of _BSD_SOURCE and _SVID_SOURCE by combining __USE_BSD and __USE_SVID into __USE_MISC. The only non-mechanical part of this patch is the changes to features.h; everything else is simple substitution of __USE_MISC for the old macros. Thus, this patch leaves obviously redundant conditionals such as "defined __USE_MISC || defined __USE_MISC", and does not update #endif comments where they referred to BSD or SVID in words instead of the literal macro name. This is intended to facilitate patch review by separating the less mechanical changes from these purely mechanical changes into a separate patch. (I do intend to integrate all the changes from <https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I believe includes all the trailing comment updates, in subsequent patches.)

* Fix infinite loop in ftell when writing wide char data (BZ #16398)Siddhesh Poyarekar2014-02-053-5/+115
| | | | | | | | | | | | | | | ftell tries to avoid flushing the buffer when it is in write mode by converting the wide char data and placing it into the binary buffer. If the output buffer space is full and there is data to write, the code reverts to flushing the buffer. This breaks when there is space in the buffer but it is not enough to convert the next character in the wide data buffer, due to which __codecvt_do_out returns a __codecvt_partial status. In this case, ftell keeps running in an infinite loop. The fix here is to detect the __codecvt_partial status in addition to checking if the buffer is full. I have also added a test case that demonstrates the infinite loop.

* Fix fwrite() reading beyond end of buffer in error pathEric Biggers2013-10-115-24/+21
| | | | | | | | | | | Partially revert commits 2b766585f9b4ffabeef2f36200c275976b93f2c7 and de2fd463b1c0310d75084b6d774fb974075a4ad9, which were intended to fix BZ#11741 but caused another, likely worse bug, namely that fwrite() and fputs() could, in an error path, read data beyond the end of the specified buffer, and potentially even write this data to the file. Fix BZ#11741 properly by checking the return value from _IO_padn() in stdio-common/vfprintf.c.

| | | | | | | | | | | In BZ #12724, partial support for POSIX 2008 fclose behavior was added.
