#1428 ValueError: misfire_grace_time must be a positive value
When I've tried to run taskcoach I've had following exception:

ValueError: misfire_grace_time must be a positive value
I've checked code and fin following line in taskcoachlib/domain/date/scheduler.py
self.__jobs[proxy] = job = self.add_interval_job(callback, days=days,
minutes=minutes, seconds=seconds, start_date=start_date, misfire_grace_time=0,
coalesce=True)
When I change misfire_grace_time=0 to misfire_grace_time=1 it can starts and looks like working right.
Changed line of scheduler.py it is line number 100
Our version of apscheduler in thirdparty should be patched to accept a 0 value as meaning "infinite". Guess I missed a spot.
Waitaminute. According to the traceback it's the system's apscheduler module that is used instead of the included one. Where did you download Task Coach ?
I've downloaded it from taskcoach site as tar package. As I understand - patched apscheduler is used in taskcoach and running taskcoach from source without building doesn't create correct version. Am I right?
I've run it just from source.
I think that happens as soon as apscheduler is installed system-wide. The Debian package didn't exist in 12.x and appeared in Raring AFAIK. You're running Raring, aren't you ?
Yep, I'm on raring :D But local library should be used before system as I remember...
As far as I can see the embedded version of the top-level package is used. But then it imports submodules and that's when the system-wide version is preferred.
A fix was made and checked into the source code repository of Task Coach. The fix will be part of the next release. You will get another notification when that release is available with the request to install the new release and confirm that your issue has indeed been fixed.
If you like, you can download a recent build from http://www.fraca7.net/TaskCoach-packages/latest_bugfixes.py to test the fix.
Because a fix has been made for this bug report, the priority of this report has been lowered to 1 and its resolution has been set to 'Fixed'.
Thanks, Task Coach development team
Thx. I've got question- I would like to write extension for importing task from jira and exporting times spent as jira 'work log'. Have you some suggestions, hints or helpful resources?
Shouldn't be too difficult. Please ask the question again on the taskcoach-dev mailing list, we'll discuss there.
This bug should be fixed in the latest release of Task Coach. Can you please install the latest release of Task Coach and confirm that this bug has indeed been fixed?
Thanks, Task Coach development team
Hi,
I got the problem with this bug. I downloaded the files from one of the earlier posts (i.e. http://www.fraca7.net/TaskCoach-packages/latest_bugfixes.py) it's running successfully on my windows, but it seems it's still not installed in the latest version. Actually we are working in a group on task coach, all of my team run latest version successfully, but I can't. I need to work on the latest version of task coach, but it's not working. Could you please suggest me a solution to this problem.
Thanks!
Hi, it's many years later, and as I close this old resolved ticket, I'm excited to tell you that https://github.com/taskcoach/taskcoach now has updated Python3 Task Coach codebase! Packages are available for some common Linux systems and we can add more.
We'd love to have you test the updated program
Cheers
