Description Stefan Seefeld 2014-01-24 00:30:18 UTC
Description of problem:

I just set up a NAS device and moved my music collection from a local filesystem to NFS (autofs, in fact). I tried to update amarok by pointing at the new location, and clicked <apply>.

After a while, amarok froze.
Using strace on the running amarokcollectionscanner to debug the issue I eventually noticed:

emop(524298, {{0, 1, SEM_UNDO}}, 1)    = 0
openat(AT_FDCWD, "/cloud/media/music/456_2", O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC) = 6
statfs("/cloud/media/music/456_2/", {f_type="NFS_SUPER_MAGIC", f_bsize=32768, f_blocks=59944387, f_bfree=56962542, f_bavail=55744542, f_files=121806848, f_ffree=121760036, f_fsid={0, 0}, f_namelen=255, f_frsize=32768}) = 0
getdents(6, /* 3 entries */, 32768)     = 80
getdents(6, /* 0 entries */, 32768)     = 0
close(6)                                = 0
write(1, "\n    <directory>\n        <path>/"..., 167) = 167
write(3, "\1\0\0\0\0\0\0\0", 8)         = 8
write(1, "\n</scanner>\n", 12)          = 12
semop(524298, {{0, -1, SEM_UNDO}}, 1 <ptrace(SYSCALL):No such process>
+++ killed by SIGKILL +++

at which point the amarok GUI became unresponsive.

This suggests two bugs:

1) the amarokcollectionscanner crashes (reliably) trying to (re-)scan my auto-mounted music collection.

2) the amarok application ends up in a deadlock because it isn't aware of the crash and (presumably) keeps waiting on a semaphore that's still locked from a non-existent process.

Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1. Start Amarok
2. Add a local collection from an auto-mounted directory
3. click <Apply> and wait

Actual results:

After a while, amarok freezes, i.e. becomes entirely unresponsive.

Expected results:

Amarok completes the import of the collection and behaves as normal.

Comment 1 Fedora End Of Life 2015-05-29 10:38:57 UTC
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. 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bug reports from releases that are no longer maintained.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 '20'.

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 20 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.

Comment 2 Fedora End Of Life 2015-06-29 14:42:41 UTC
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 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. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.
