Created attachment 580228 [details] gdb traceback from a deadlocked yum process Description of problem: Pressing ^C while yum downloads deltas seems to cause pycurl to deadlock while waiting on two different locks, neither of which appears to be the GIL. (I could be wrong about that, though.) strace says the process is stuck at "futex(0x87dffd0, FUTEX_WAIT_PRIVATE, 0, NULL". See the attached backtrace for details. Version-Release number of selected component (if applicable): libcurl-7.21.7-7.fc16.x86_64 python-2.7.2-5.2.fc16.x86_64 python-pycurl-7.19.0-9.fc15.x86_64 yum-3.4.3-23.fc16.noarch How reproducible: Always, at least on my system Steps to Reproduce: 1. sudo yum upgrade 2. Press ^C while yum downloads deltas Actual results: Yum hangs Expected results: Yum changes mirrors
Reassigning to yum-presto based on yum developers' advice
It is also not possible to interrupt the "rebuilding" phase which I assume don't involve curl and which I would assume used atomic renames for the generated output and thus securely could be interrupted at any point. The problem might thus be broader than described.
This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '16'. 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 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 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 to click on "Clone This Bug" and open it against that version of Fedora. 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. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
