First resource limit is maximum number of open file descriptors limit, second one being limit for maximum writable file size.

With resource lib we set the limit for the current process (tested with my testing scripts) and its children processes. By testing pre-upgrade and upgrade I found a threshold of max. open file descriptors to be around 512, (the default value for ulimit -n is 1024) so a small multiplier of the default value shouldn't be a problem to set. With writing size there shouldn't be a problem to set it to "infinity".

Both problems from the tickets were solved, but there could be other side effects.

Resolves: RHEL-26459 and RHEL-16881

Thank you for contributing to the Leapp project!

Please note that every PR needs to comply with the Leapp Guidelines and must pass all tests in order to be mergeable.
If you want to request a review or rebuild a package in copr, you can use following commands as a comment:

  • review please @oamg/developers to notify leapp developers of the review request
  • /packit copr-build to submit a public copr build using packit

Packit will automatically schedule regression tests for this PR's build and latest upstream leapp build.
However, here are additional useful commands for packit:

  • /packit test to re-run manually the default tests
  • /packit retest-failed to re-run failed tests manually
  • /packit test oamg/leapp#42 to run tests with leapp builds for the leapp PR#42 (default is latest upstream - master - build)

Note that first time contributors cannot run tests automatically - they need to be started by a reviewer.

It is possible to schedule specific on-demand tests as well. Currently 2 test sets are supported, beaker-minimal and kernel-rt, both can be used to be run on all upgrade paths or just a couple of specific ones.
To launch on-demand tests with packit:

  • /packit test --labels kernel-rt to schedule kernel-rt tests set for all upgrade paths
  • /packit test --labels beaker-minimal-8.10to9.4,kernel-rt-8.10to9.4 to schedule kernel-rt and beaker-minimal test sets for 8.10->9.4 upgrade path

See other labels for particular jobs defined in the .packit.yaml file.

Please open ticket in case you experience technical problem with the CI. (RH internal only)

Note: In case there are problems with tests not being triggered automatically on new PR/commit or pending for a long time, please contact leapp-infra.

I don't really like the redundancy of code here, but I'm not sure where should the common logic be placed.

I think commands/command_utils.py is an option. There is already some code the commands share.

Tested for both maximum file size and maximum open fd's, works as expected.
Tested by setting a limit low enough that leapp fails without this patch and confirming it then works with it.

However unit tests are missing.

First resource limit is maximum number of open file descriptors limit,
second one being limit for maximum writable file size. Plus add unit
tests.

LGTM

NOTE: If this breaks local tests in containers for you, just rebuild them (make clean_containers and then it will be rebuilt the next time you run make test_container)

## Additional changes interesting for devels
- Introducing new upstream documentation focused on the leapp-repository
  project at https://leapp-repository.readthedocs.io/introduce-docs/.
  The documentation is still under reconstruction at this time, however we
  consider it a big step. All PRs impacting stuff that should be documented
  will be required to do so before they could be merged.
