2022-01-01Update copyright dates with scripts/update-copyrightsPaul Eggert
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 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines
2021-09-03Remove "Contributed by" linesSiddhesh Poyarekar
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>
2021-07-09Force building with -fno-commonFlorian Weimer
As a result, is not necessary to specify __attribute__ ((nocommon)) on individual definitions. GCC 10 defaults to -fno-common on all architectures except ARC, but this change is compatible with older GCC versions and ARC, too. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

Also, change sources.redhat.com to sourceware.org. This patch was automatically generated by running the following shell script, which uses GNU sed, and which avoids modifying files imported from upstream: sed -ri ' s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g ' \ $(find $(git ls-files) -prune -type f \ ! -name '*.po' \ ! -name 'ChangeLog*' \ ! -path COPYING ! -path COPYING.LIB \ ! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \ ! -path manual/texinfo.tex ! -path scripts/config.guess \ ! -path scripts/config.sub ! -path scripts/install-sh \ ! -path scripts/mkinstalldirs ! -path scripts/move-if-change \ ! -path INSTALL ! -path locale/programs/charmap-kw.h \ ! -path po/libc.pot ! -path sysdeps/gnu/errlist.c \ !

2017-06-23Avoid .symver on common symbols [BZ #21666]H.J. Lu
The .symver directive on common symbol just creates a new common symbol, not an alias and the newer assembler with the bug fix for https://sourceware.org/bugzilla/show_bug.cgi?id=21661 will issue an error. Before the fix, we got $ readelf -sW libc.so | grep "loc[12s]" 5109: 00000000003a0608 8 OBJECT LOCAL DEFAULT 36 loc1 5188: 00000000003a0610 8 OBJECT LOCAL DEFAULT 36 loc2 5455: 00000000003a0618 8 OBJECT LOCAL DEFAULT 36 locs 6575: 00000000003a05f0 8 OBJECT GLOBAL DEFAULT 36 locs@GLIBC_2.2.5 7156: 00000000003a05f8 8 OBJECT GLOBAL DEFAULT 36 loc1@GLIBC_2.2.5 7312: 00000000003a0600 8 OBJECT GLOBAL DEFAULT 36 loc2@GLIBC_2.2.5 in libc.so.

2015-08-16Desupport regexp.h (bug 18681)Zack Weinberg
2015-08-01Deprecate the use of regexp.hZack Weinberg
<regexp.h> (not to be confused with <regex.h>) is an obsolete and frankly horrible regular expression-matching API. It was part of SVID but was withdrawn in Issue 5 (for reference, we're on Issue 7 now). It doesn't do anything you can't do with <regex.h>, and using it involves defining a bunch of macros before including the header. Moreover, the code in regexp.h that uses those macros has been buggy since its creation (in 1996) and no one has noticed, which indicates to me that there are no users. (Specifically, RETURN() is used in a whole bunch of cases where it should have been ERROR().) The header is given a warning and marked deprecated for 2.22. See: https://sourceware.org/ml/libc-alpha/2015-07/msg00862.html and https://sourceware.org/ml/libc-alpha/2015-07/msg00871.html.
