I did a bulk update in the database to change our forum URL from one location to another. (Updated the field Content in the Revisions table.)

Now a large number of entries in the cache are stale.

I grepped in the cache directory tree for the old url, and found it present in files in several subdirectories of the cache/views folder for the web in question. I saw it in the subdirectories source, tex, revision, …

In addition, the old URL is present in files in the top-level folder “storage.”

What is the cleanest / simplest / safest way to purge the entire cache?

Thanks!

What is the cleanest / simplest / safest way to purge the entire cache?

At the commandline, do an

rm -R

of the appropriate directory. There isn’t a GUI tool to do it.

In addition, the old URL is present in files in the top-level folder “storage.”

Those can all be deleted.

Can we make the instructions more specific, because I’m cautions about disrupting a structure that I don’t understand.

How about:

rm instiki/storage/*

rm -r instiki/cache/views/azimuth

There’s a whole structure of directories and files under the last directory, that’s okay to wipe out?

How about:

rm instiki/storage/*

That should be fine.

rm -r instiki/cache/views/azimuth

As should that.

All of those will be recreated, as needed.

Thanks, I did that.

It seems to be working fine, but one thing puzzles me. About a day after I cleared everything out as per the above, the full tree under instiki/cache/views/azimuth got repopulated – presumably when the site got crawled.

But the storage folder didn’t get repopulated. Or rather, now there is just a single file in it: azimuth-markdownMML-2015-02-12-11-11-03.zip, with a timestamp of yesterday.

Before I cleared out storage, there were tons of files it in, it looked something like one file per page of the wiki, though I didn’t look closely.

Does this make sense; are there any signs of ill-health here? What is the function of the storage folder?

Thanks.
