Use the following template to for the 'fedpkg update' request to submit an update for this issue as it contains the top-level parent bug(s) as well as this tracking bug. This will ensure that all associated bugs get updated when new packages are pushed to stable. ===== # bugfix, security, enhancement, newpackage (required) type=security # testing, stable request=testing # Bug numbers: 1234,9876 bugs=1197798,1197799 # Description of your update notes=Security fix for # Enable request automation based on the stable/unstable karma thresholds autokarma=True stable_karma=3 unstable_karma=-3 # Automatically close bugs when this marked as stable close_bugs=True # Suggest that users restart after update suggest_reboot=False ====== Additionally, you may opt to use the bodhi update submission link instead: https://admin.fedoraproject.org/updates/new/?type_=security&bugs=1197798,1197799 This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 EOL if it remains open with a Fedora 'version' of '21'. 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. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 21 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 this bug is closed as described in the policy above. 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. Still present in Rawhide. This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle. Changing version to '24'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora24#Rawhide_Rebase This message is a reminder that Fedora 24 is nearing its end of life.

The upstream bug reference was incorrect. I fixed that, and the bug has indeed not been fixed. This bug has been reported against a Fedora version which is already unsuported. In compliance with FESCo decision how to handle EOL of Security issues [1], I am changing the version to '27', the latest supported release. Please check whether this bug is still an issue on the '27' release. If you find this bug not being applicable on this release, please close it. [1] https://pagure.io/fesco/issue/1736 This message is a reminder that Fedora 27 is nearing its end of life. On 2018-Nov-30 Fedora will stop maintaining and issuing updates for Fedora 27. 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 EOL if it remains open with a Fedora 'version' of '27'. 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. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 27 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 this bug is closed as described in the policy above. 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. This was fixed in glibc 2.28, and so Fedora 29 and onwards have the fix. Therefore the only affected releases are F27 and F28, but since F27 is going EOL we will only look at F28. This message is a reminder that Fedora 28 is nearing its end of life. On 2019-May-28 Fedora will stop maintaining and issuing updates for Fedora 28. 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 EOL if it remains open with a Fedora 'version' of '28'.

Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 28 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 this bug is closed as described in the policy above. 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. We have decided not to fix this in F27 or F28 since it requires a rebase of the entire regular expression parsing subsystem. Instead we recommend users upgrade to the supported F29 and onwards. |
