* Remove "Contributed by" linesSiddhesh Poyarekar2021-09-031-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | We stopped adding "Contributed by" or similar lines in sources in 2012 in favour of git logs and keeping the Contributors section of the glibc manual up to date. Removing these lines makes the license header a bit more consistent across files and also removes the possibility of error in attribution when license blocks or files are copied across since the contributed-by lines don't actually reflect reality in those cases. Move all "Contributed by" and similar lines (Written by, Test by, etc.) into a new file CONTRIBUTED-BY to retain record of these contributions. These contributors are also mentioned in manual/contrib.texi, so we just maintain this additional record as a courtesy to the earlier developers. The following scripts were used to filter a list of files to edit in place and to clean up the CONTRIBUTED-BY file respectively. These were not added to the glibc sources because they're not expected to be of any use in future given that this is a one time task: https://gist.github.com/siddhesh/b5ecac94eabfd72ed2916d6d8157e7dc https://gist.github.com/siddhesh/15ea1f5e435ace9774f485030695ee02 Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* Update copyright dates with scripts/update-copyrightsPaul Eggert2021-01-021-1/+1
| | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

* Fix strftime wcschr namespace (bug 17634).Joseph Myers2014-12-101-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use of strftime, a C90 function, ends up bringing in wcschr, which is not a C90 function. Although not a conformance bug (C90 reserves wcs*), this is still contrary to glibc practice of avoiding relying on those reservations; this patch arranges for the internal uses to use __wcschr instead, with wcschr being a weak alias. This is more complicated than some such patches because of the various IFUNC definitions of wcschr (which include code redefining libc_hidden_def in a way that involves creating __GI_wcschr manually and so also needs to create __GI___wcschr after the change of internal uses to use __wcschr). Tested for x86_64 and 32-bit x86 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). 2014-12-10 Joseph Myers <joseph@codesourcery.com> Adhemerval Zanella <azanella@linux.vnet.ibm.com> [BZ #17634] * wcsmbs/wcschr.c [!WCSCHR] (wcschr): Define as __wcschr.
