git-gui: How to configure for use in gigantic projects?

[Birger Skogeng Pedersen]

Hi,

I would like to use git gui for a project. The problem is that the
repository directory is really gigantic. Doing a scan (F5) takes a
couple of minutes to finish.

I would like the scan to only focus on files that are specifically
added to the index. In git I do this:

git config status.showUntrackedFiles no

git status will then only show status of files that I have
specifically added. So git status completion is instant.

But this configuration appears to have no effect on git-gui. The scan
is just as slow as before.

Anything I can do to make git-gui only scan files that are
specifically added, and not look through the whole directory?

FWIW, there are better ways to improve performance of git status without
hiding untracked files (which are useful to see when new files are added):

* Add all uninteresting files and directories to .gitignore
* Use fast storage for git repository, e.g. NVME-based
* If your OS can handle filesystem cache efficiently (e.g., Linux) make sure 
there is enough of free RAM for caches and all repeated operations on
same files and directories will speed up dramatically
* If your OS cannot handle filesystem cache efficiently (e.g. Windows) consider
using different OS for development
* If overall performance is still not sufficient, consider using fsmonitor hook [1]

Uncheck "Show untracked files" in options. It is controlled by the 
config 'gui.displayuntracked'.

Ah, that one changed everything! Thank you Pratyush!

I've found that enabling Trust File Modification Time helps, at the cost 
of git-gui doing (very) occasional rescans when it notices that a file 
it thought was modified turns out to be unmodified.  As Konstantin said, 
things generally improve once the initial scan primes the disk cache.  YMMV.

The setting is in the Preferences, or "git config gui.trustmtime true".
