Just installed the latest update. jAlbum 34 _ Java 20, 64 bit.

I never had any issues in the past "Creating Album"; now I'm getting a page full of errors. I don't know if this is a jAlbum issue or if the update has made the theme/skin wonky, but it looks like this was not well tested or I'm missing something.

As Reported:

An unexpected error occurred. Please see detailed description below:

Jeff,

Too late to try that. I had a thought that it might be Java-related (might be right, might be wrong), so I rebooted the system.

It's now processing the album, but what used to take about 15 to 20 minutes is now showing 45 minutes (1/4 of the way through 24,805 photographs). Slowed down something horrible.

I reprocessed 800 odd photographs, so I deleted the old albums and added the new ones.

BTW - Happy New Year and all that ...

Good morning Jeff,

I was not aware that it was Java based. The reboot probably cleared some clash that was happening in memory or a cache, or it was needed to overwrite some files that were open, and the reboot was needed to overwrite them.

Anyways, it did all work OK after that, but it was a lot slower. It seemed to end up being about 50 to 60% slower than the previous version.

Unfortunately, I don't have any true timings on this. Hopefully, someone in SQA could test this. And I'd be happy to be proven wrong.

That's what the "j" stands for.

Very mysterious. I've got a family album with over 6,000 objects, about 95% still images, the rest videos, in over 50 folders. If I simply Make Album, without adding any new objects, it regenerates all of the index pages (there's a time stamp buried in the page code, so each index.html is "new"), and finishes the job in 20 seconds.

That doesn't really change if I alter things like titles, comments, or the sequence of objects - it has to extract all that information to build the index page whether there are any changes or not.

If I add new objects, the processing time for the album increases by about the same amount it would if I were creating a new album with just those objects in it.

The oldest material, of course, has virtually no metadata, but everything since about 2006 is from the digital era, and has the usual collection of metadata.

It's difficult to imagine what could be choking your album builds. The only thing I can think of is that the generation of the JSON files could be the problem. My skins don't use JSON files, so I turn off their generation - it would just be a waste of time. I may have to do some experimenting with that.

Well, so much for that theory. When I turned JSON generation on, and made the album again, the build time was within a tenth of a second of the "no JSON" build.

If you ever encounter "odd pauses" during album builds in the future, open jAlbum's system console and hit the "dump threads" button in the top-right corner. This will produce a file telling me what jAlbum is up to. Just attach it in a thread here.
