Red Hat Bugzilla – Bug 801423
pending requests are lost on peer disconnect
Last modified: 2015-02-17 09:09:58 EST
We use libdbus in sssd in a p2p fashion.
We have a wrapping layer that manages integration with our mainloop (watchers/timeouts/etc).
We found out that when we use dbus_connection_send_with_reply() with a timeout and then dbus_pending_call_set_notify() with a reply handler (and w or w/o a function to free user data) and the connection drops before the peer sends a reply that the timeout never fires nor user data is ever freed.
We see that all timeouts are simply dropped when dbus realizes the connection is gone (usually the first time we try to send a new request), and pending calls are simply forgotten.
We have worked around the problem by independently keeping track of pending calls, and killing our outer requests when this happens, but it seem like dbus should wakeup the reply_handler once it realizes the connection has been dropped and return some sort of error.
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.
(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)
More information and reason for this action is here:
This message is a notice that Fedora 19 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 19. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.
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 19 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.
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 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.
