Zope's zCatalog is a way of creating indexes to improve performance.
Zwiki:HowToInstallAZwikiCatalog describes the manual process
- it's not clear to me why many of those properties need to be indexed. For instance, lastEditTime is what it seems, but last_edit_time is its string representation, which seems unlikely to be searched or sorted on.
I want an automated process so I can do it on customer sites. Also my Get Slice problem makes it impossible to do it the manual way.
I didn't think an External Method was was great approach, because
it doesn't seem to use acquisition for context, so you need to either pass a location as a parameter or set up the method within the target folder (which is how its written there) which gets back to my Get Slice problem
if you need to tweak it you have to work outside Zope, then get the ZMI to re-recognize the new version, which didn't seem automatic when I tried it.
But I tried it that way anyway just to avoid confusion. Hah.
Copied external method. Ripped out the pieces specific to the Issue Tracker.
- but I did leave some of the properties. Maybe that was a bad idea?
Ran external method. Got error message "index already exists" (not the exact phrasing). No catalog created. Tried a couple times with the same result.
Tried creating a catalog by hand. Noticed that it added some index and Meta Data tables automatically.
Tried deleting that catalog, removing the automatically-added indexes from the external method, then running it again. No go.
Tried adding the catalog by hand, then tweaking the method so that it wouldn't create a new catalog, but just add indexes, etc. It gave me the same error message! But on inspection all the right stuff had been added to the catalog!
the code was designed for an empty folder, so I have to figure out how to automate the manage_findObjects function. There doesn't seem to be much documentation around for this.
still buried back in that Get Slice problem.
Unless I find a problem, I'll try and convert this to a Python Script and figure out the manage_findObjects piece to add. Or maybe I'll give a last try with the external method after ripping out the Issue Tracker properties.
tried a one-line script to create a catalog --BillSeitz, 2003/06/30 20:41 GMT
'catalog = [Z Catalog]'
I wonder whether this approach will get me around the problem? Ugh, it looks like that would still require mucking around outside ZMI.
just do it manually for now --BillSeitz, 2003/07/17 15:54 GMT
My priority is to improve performance of the whole server by getting my big wiki indexed. I can play with other methods later.
hmm, it's still slow --BillSeitz, 2003/07/17 15:58 GMT
Apparently still not using the catalog - DTML code shows a 'bruteforce' flag, don't know where that's set, or whether it's obsolete.
just rip out pieces for now --BillSeitz, 2003/07/17 16:46 GMT
to force it to use the Catalog.
Unfortunately, references to 'src' for the contents of the blogbit pages kicks out garbage. I have an ugly feeling they'd need to be included in the Catalog. Unless maybe I do some sort of lookup from the page 'id' that's in the cache to the page contents that's not in the cache?
use Principia Search Source? --BillSeitz, 2003/07/17 21:54 GMT
When I created the catalog this was included as a default Index and Metadata column, and I didn't delete it.
So I thought - hey, maybe I can use that instead of 'src'.
But it has the same weird effect - it sucks in the Front Page contents instead of the indexed-page contents. Weird.
duh, just realized it has an index but not a metadata column
also, after deciding not to work with it for now, dumped its index to cut that overhead.
if add 'src' to metadata --BillSeitz, 2003/07/17 23:21 GMT
Don't do it directly, but make a Python Method to return just some subset of it (first 2000 chars).
Hmm, if done right could use this for non-blog pages, too. Or, maybe prefer to render canonicalLinks for those? Or both?
got response --BillSeitz, 2003/07/18 00:24 GMT
needed to use 'getObject()' and 'text()'
- also there are other things to look at there
remember to fix test for catalog --BillSeitz, 2003/07/18 00:26 GMT
Ripped that out before.
And Zwiki:ZwikiBlog doesn't test - it just assumes there's a catalog.
other places to reference catalog --BillSeitz, 2003/07/18 21:52 GMT
