This is to fix the error when pushing to personal gitlab repo:
|
|
|
|
|

2024-07-04 08:16:05,460 Running: 'git clone --recursive --shared /builds/pfilipen/samba /builds/samba-testbase/master' in '/builds/pfilipen/samba'

To add an exception for this directory, call:

git config --global --add safe.directory /builds/pfilipen/samba/.git
|
|
|
|
|
fatal: Could not read from remote repository.
|
|
|
|
|
|
|
|
|
|
Instead of adding more and more explicit repositories
|
|
|
|
|
we should just allow any, we're in an isolated environment...

This fixes a O(n²) performance regression in notifyd. The problem was
|
|
|
|
|
that we had a watcher per notify instance. This changes the code to have
|
|
|
|
|
a watcher per notify db entry.
