[PATCH 2/5] gitweb: Faster project search

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Before searching by some field the information we search for must be
filled in.  For this fill_project_list_info() was enhanced in previous
commit to take additional parameters which part of projects info to
fill.  This way we can limit doing expensive calculations (like
running git-for-each-ref to get 'age' / "Last changed" info) only to
projects which we will show as search results.

With this commit the number of git commands used to generate search
results is 2*<matched projects> + 1, and depends on number of matched
projects rather than number of all projects (all repositories).

Note: this is 'git for-each-ref' to find last activity, and 'git config'
for each project, and 'git --version' once.

search_projects_list() now pre-fills required parts of project info by
itself, so running fill_project_list_info() before calling it is no
longer necessary and actually you should not do it.
