@dannylamb I'm sorry I didn't catch you sooner, but couldn't we set this as an option in the blueprint.XML so you don't have to do this?

https://github.com/Islandora/Alpaca/blob/dev/islandora-indexing-fcrepo/src/main/resources/OSGI-INF/blueprint/blueprint.xml#L26

[dannylamb]

@whikloj Depends on the type of parameter IIRC. Some can be set on the http component and some are done on a per endpoint basis. I'll look that up because if we can do it once in the blueprint, we should.

[dannylamb]

Bit of a wormhole but.... I think we already have the groundwork laid for this. I can make an HttpClientConfigurer and add it as a bean here. Then it should be exported out and affect all http components used in Karaf.

Also... sneaky claw reference!!!

[antbrown]

This works for us, I haven't noticed any regressions after upgrading, and the ability to pass huge files around the place is really cool.

Thank you!

checkstyle fail for long lines

@dannylamb, do you want to revisit this so we can pull it over the finish line?

Hi all,
Any updates for this patch?
We're having the same problem in loading large video file in Islandora 8 (version 2.2.1) without this patch. It's ok to load and generate small video files (<100 MB), but it will retry the generating service file process several times for large video files and get frozen. The service files are not generated for them ofc.
Simon.

[seth-shaw-unlv]

@simonhm , I believe this patch was superseded and incorporated into 7bf983d (available as part of the latest release).

@whikloj or @dannylamb , can either of you confirm and close this PR?

[whikloj]

Yes this was added to the new one jar, you can find it here.

[simonhm]

We've been testing Islandora 8 using the Ansible Playbook. The Alpaca version on our testing sites is 1.x that was installed in the initial set up. We've been updating PHP modules and Drupal but everything else in the stack is what was initially installed.
I think it's better if the Alpaca version in Ansible Playbook or Docker is 2.x instead of 1.x. Thanks!
Simon.

Hi @simonhm,
The islandora-playbook now installs the new Alpaca all-in-one jar, however before trying to update you might want to wait for Islandora-Devops/islandora-playbook#210
