Description Daniel Berrangé 2011-10-10 21:26:38 UTC
Description of problem:
Applications can use  gp_camera__wait_for_event to wait for notifications from the camera. This method includes a timeout parameter to avoid it blocking forever. This is not working, at least for my Nikon camera, blocking forever.

This makes the entangle application unusable, since its function is blocked for a timeout that never comes

Version-Release number of selected component (if applicable):
2.4.10.1

How reproducible:
With a Nikon D90

Steps to Reproduce:
1. It is pretty hard to reproduce this, but I see it with entangle
2. Connect to a camera in Entangle
3. Click the 'capture' button
  
Actual results:
Capture never completes, gdb shows it stuck on gp_camera_wait_for_event

Expected results:
Capture works normally

Additional info:
Updating to the 2.4.11 release present in F16 works. I have not been able to identify the upstream fix that solved this, so don't know whether its backportable to 2.4.10.1, or whether a rebase is the only option to fix this.

I'd really like this fixed in a F15 update since it makes entangle unusable

Comment 1 Fedora End Of Life 2012-08-07 16:35:53 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached 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" (top right of this page) 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:
