Option to skip revisions with lots of added files

[moisei]

On the real production systems with several millions LOC, it should be possible to skip the revisions that contain initial import of the sources into svn. Such a revisions could contain thousands of files and to trac it takes a hours to process such a revision, probably because of the indexing or code diff calculation.

The request is to have an option to skip such a revision, i.e. either make them invisible to trac somehow, or make trac know to take the special care of such a cases. Ideally, trac could detect such a revisions by itself and proceed according to some config. The huge revisions could be detected by the size of the revision file, for example.

With Trac 0.11, the TracFineGrainedPermissions (authz_policy style) should allow you to block some specific revisions.

Could you please have a try of this approach?

For the auto-detection part, there's already two settings that you can tweak, see TracIni#changeset-section (max_diff_...).

However, if the expensive changeset consists of only ADDed files, then this won't help. It might be worth adding a max_added_files entry, and once the number of added files is above that limit, we only show the parent folders, and not every added files.
