pipeline.exceptions.CompressorError

[ErikEvenson]

I occasionally (once every 10 runs or so?) get this error when django-pipeline is compressing my JS:

Traceback (most recent call last):

pipeline.exceptions.CompressorError: Killed

The only way I have found to continue is to restart the vagrant box that I am developing on.

It looks like yuglify command gets killed while pipeline runs it. Maybe it crashed or get killed by something else?

[rickeyvisinski-kanban]

This is fixed by #281. Something in the js caused Yuglify to send an error message to stderr and and stderr output raised a fatal exception.

@cyberdelia, has the latest release been pushed with this fix?

[cyberdelia]

@rickeyvisinski-kanban Yes it does.

[rickeyvisinski-kanban]

Great, thanks.

[ErikEvenson]

This seems to be happening more often in 1.3.23.

[rickeyvisinski-kanban]

It is because something is causing the yuglify command to exit with a non-zero exit code. I don't know the yuglify specific error codes, but there is some kind of error compression. Try running yuglify outside of pipeline to uncover what the actual error is.

I just wanted to update that this is still happening in pipline v1.4.3 and yuglify v0.1.4. Switched to https://github.com/mishoo/UglifyJS2/ for the mean time.

[ErikEvenson]

For what it is worth, I'm running pipeline 1.3.23 and yuglify 0.1.4 and haven't seen the error in a long time. Guess I should look into upgrading to 1.4 sometime...

[cyberdelia]

Closing as it seems to be resolved.

[thanos]

Still open
python2.7

django-pipeline==1.5.0
Django==1.8.1
yuglify@0.1.4

Crashing is normal but some decent error hanlding would be good.

Also still seeing this in 1.5.4

[smrrrazu]

Still having this problem with django-pipeline==1.6.8
