zc.catalog
zc.catalog is an extension to the Zope 3 catalog, Zope 3’s indexing and search facility. zc.catalog contains a number of extensions to the Zope 3 catalog, such as some new indexes, improved globbing and stemming support, and an alternative catalog implementation.
zc.catalog changes
The 1.2 line supports Zope 3.4/ZODB 3.8. The 1.1 line supports Zope 3.3/ZODB 3.7.
1.2dev
Features added
zc.catalog now can use 64-bit BTrees (“L”) as provided by ZODB 3.8.
Albertas Agejavas (alga@pov.lt) included the new CallableWrapper, for when the typical Zope 3 index-by-adapter story (zope.app.catalog.attribute) is unnecessary trouble, and you just want to use a callable. See callablewrapper.txt. This can also be used for other indexes based on the zope.index interfaces.
1.1.1 (2007-3-17)
Bugs fixed
‘all_of’ would return all results when one of the values had no results. Reported, with test and fix provided, by Nando Quintana.
1.1 (2007-1-6)
Features removed
The queueing of events in the extent catalog has been entirely removed. Subtransactions caused significant problems to the code introduced in 1.0. Other solutions also have significant problems, and the win of this kind of queueing is qustionable. Here is a run down of the approaches rejected for getting the queueing to work:
_p_invalidate (used in 1.0). Not really designed for use within a transaction, and reverts to last savepoint, rather than the beginning of the transaction. Could monkeypatch savepoints to iterate over precommit transaction hooks but that just smells too bad.
_p_resolveConflict. Requires application software to exist in ZEO and even ZRS installations, which is counter to our software deployment goals. Also causes useless repeated writes of empty queue to database, but that’s not the showstopper.
vague hand-wavy ideas for separate storages or transaction managers for the queue. Never panned out in discussion.
1.0 (2007-1-5)
Bugs fixed
adjusted extentcatalog tests to trigger (and discuss and test) the queueing behavior.
fixed problem with excessive conflict errors due to queueing code.
updated stemming to work with newest version of TextIndexNG’s extensions.
omitted stemming test when TextIndexNG’s extensions are unavailable, so tests pass without it. Since TextIndexNG’s extensions are optional, this seems reasonable.
removed use of zapi in extentcatalog.
0.2 (2006-11-22)
