* | Remove "Contributed by" lines | Siddhesh Poyarekar | 2021-09-03 | 1 | -1/+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-copyrights | Paul Eggert | 2021-01-02 | 1 | -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 | ||||
* | nptl: Fix PTHREAD_PRIO_PROTECT timed lock | Adhemerval Zanella | 2020-11-27 | 1 | -1/+11 |
| | | | | | | | | | | | | | | | | | The 878fe624d4 changed lll_futex_timed_wait, which expects a relative timeout, with a __futex_abstimed_wait64, which expects an absolute timeout. However the code still passes a relative timeout. Also, the PTHREAD_PRIO_PROTECT support for clocks different than CLOCK_REALTIME was broken since the inclusion of pthread_mutex_clocklock (9d20e22e46) since lll_futex_timed_wait always use CLOCK_REALTIME. This patch fixes by removing the relative time calculation. It also adds some xtests that tests both thread and inter-process usage. Checked on x86_64-linux-gnu. | ||||
* | nptl: Return EINVAL for pthread_mutex_clocklock/PI with CLOCK_MONOTONIC [BZ ↵ | Adhemerval Zanella | 2020-11-25 | 1 | -0/+2 |
| | | | | | | | | | | | | | | | | #26801] Linux futex FUTEX_LOCK_PI operation only supports CLOCK_REALTIME, so pthread_mutex_clocklock operation with priority aware mutexes may fail depending of the input timeout. Also, it is not possible to convert a CLOCK_MONOTONIC to a CLOCK_REALTIME due the possible wall clock time change which might invalid the requested timeout. Checked on x86_64-linux-gnu and i686-linux-gnu. Reviewed-by: Lukasz Majewski <lukma@denx.de> | ||||
