Since 5.16.0, perl segfaults when using glob in multi-threaded environment. This has been reported to upstream as <https://rt.perl.org:443/rt3/Ticket/Display.html?id=117823>. Tests case: use warnings; use strict; use threads; use threads::shared; my $nthread = 20; sub work { foreach (1..10000) { my @files = <*.supp>; } } my @threads; foreach my $i (1..$nthread) { push @threads, threads->create(\&work); } foreach my $t (@threads) { $t->join(); }
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
The fix is emerging in <https://rt.perl.org/rt3/Public/Bug/Display.html?id=119897>.
Upstream fix is in blead now: commit facf34ef484d62d15b2da11ee03d01942a22ff15 Author: Brian Fraser <fraserbn> Date: Sat Sep 21 03:19:52 2013 -0300 File::Glob: Dup glob state in CLONE() This solves [perl #119897] and [perl #117823], and restores the behavior of glob() in conjunction with threads of 5.14 and older. Since 5.16, code that used glob() inside a thread had been unintentionally sharing state between threads, which lead to things like this crashing and failing assertions: ./perl -Ilib -Mthreads -e 'scalar glob("*"); threads->create(sub { glob("*")
This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '18'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 18's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Issue in F19 too. We have patch which should be applied.
The fix has been in 5.18.2 (perl-5.18.2-289.fc20).
