[Dltk-dev] Re: New indexing infra

[Michael Spector <spektom@xxxxxxxxx>]

Hi guys,

I would like to merge these changes made in INDEX2 branch into HEAD. New indexing infrastructure should not affect other plug-ins - it works only if enabled explicitly. Please review the changes and report any issues that you see.

Affected plug-ins (INDEX2 branch):

DLTK:
------
org.h2.core
org.eclipse.dltk.core
org.eclipse.dltk.core.h2

PDT:
-----
org.eclipse.php.core
org.eclipse.php.core.h2
org.eclipse.php.ui

Thanks in advance,

Michael

Hi All,

I've just committed new indexing infrastructure into special 'INDEX2' branch. This index is going to solve one of the huge performance bottle-necks in DLTK: JDT style index performing a lot of IO operations. Affected plug-ins are:

org.eclipse.dltk.core - Abstract indexing infrastructure under 'index2' source folder.

org.eclipse.dltk.core.h2 - Index implementation using H2 database.

org.h2.core - H2 Database (licensed under EPL)

To see live example that uses this index please refere to PDT plug-in: org.eclipse.php.core.h2 (HEAD). I must admit, that performance has been improved dramatically with new index without changing the flow - just replacing old SearchEngine call with new one.

The next step will be adapting existing usages of JDT-style SearchEngine in DLTK Core/UI to this index (may be through some extension point).

Please look at these plug-ins, and lets discuss it!

Thanks a lot for your time,
