FileChecker has not attribute 'order'

[graipher]

While trying to implement the workaround mentioned by @drmarkwslater in GANGA-385, I am running into this error with FileChecker:

Traceback (most recent call last):

AttributeError: 'FileChecker' object has no attribute 'order'

Corresponding code in my submission script:

postprocessors = [
        FileChecker(files=['stdout'], searchStrings=['INFO Application Manager Terminated successfully'], failIfFound=False, checkMaster=False)]
if args.evtmax < 0:
    postprocessors.append(LHCbCompleteChecker())
    if all(isinstance(f, LogicalFile) for f in j.inputdata):
        postprocessors.append(LHCbBookkeepingChecker())
for pp in postprocessors:
        j.postprocessors.append(pp)

This is being caused by a proxied object getting though the proxy layer. It should be fixed with #393 but we'll have to run some tests.

[graipher]

OK, thanks.
BTW when is 6.19 expected to be released/when can I at least easily test it with SetupProject Ganga --dev v601r19?

[rob-c]

Due to not wanting to have to support branches in various different stages of development we're not providing Ganga in the dev area between releases for every release.
To install it yourself from git see: http://ganga.readthedocs.org/en/latest/UserGuide/InstallAndBasicUsage.html

If you need some help feel free to send a pm after trying to install it

@graipher I am unable to reproduce this in 6.1.19. Do you have a minimal reproducible example which I can test against? LHCbCompleteChecker and LHCbBookkeepingChecker are not Ganga classes.

[graipher]

Hey @milliams,
I can also not reproduce this anymore in 6.1.19, with these custom classes.
Maybe it was fixed by whatever fixed #270?

[graipher]

Also, before already FileChecker (which is an official Ganga class, right?) was failing with this error, so deleting everything after that should produce a reproducible example (failing in 6.1.18, succeeding in 6.1.19).

[milliams]

@graipher Cheers. Indeed I can reproduce this in 6.1.17 and it is fixed in at least develop and apparently in 6.1.19.
