prCommitsPerRunLimit is only checked after each repository

[Algram]

What Renovate type are you using?

Selfhosted renovate on GitLab
Version 19.93.2 from the renovate:19 docker image.

Describe the bug
It seems that renovate is only checking if the prCommitsPerRunLimit is reached after a complete repository run.

To Reproduce

• We have three repositories to renovate and prCommitsPerRunLimit: 2
• The first repository only needs a single commit
• Renovate commits 1 time on the first repository
• The second repository needs 50 commits
• Renovate commits 50 times on the second repository
• The third repository needs 10 commits
• Renovate says the limit is reached and stops.

Additional information
Renovate should check the limit on each and every commit and not at the end of renovating a repo.

Imo this is the relevant part of the feature where it only checks after each repo:

It seems that renovate is only checking if the prCommitsPerRunLimit is reached after a complete repository run.

The limit should be already checked at the start of every branch:

renovate/lib/workers/repository/process/write.ts

Line 38 in 409c1c5

prsRemaining <= 0 || getLimitRemaining('prCommitsPerRunLimit') <= 0,

.. and each branch should have maximum one commit.

Please try to reproduce in a public repo or repos and then save the logs at debug level. Based on your description, it should not be necessary to have multiple repos or a limit > 1. i.e. a single repo with 2 branches needing creation and a limit of 1 should be enough to reproduce.
