Files with extension '.diff' are consider as git patches by apply script.
A file for PyTorch PR N needs to be named 'N.diff'.
Patch files which are not related to PyTorch PRs, should begin with an 'X' character, followed by a two digit number, followed by a dash ('-'), a name, and '.diff'. Example:
X10-optimizer.diff
Patch file are alphabetically ordered, so PyTorch PR patches are always applied before the non PyTorch ones.
There's a special file torch_patches/.torch_pin, which is used to coordinate landing PRs in
pytorch/pytorch and pytorch/xla.
To test a pytorch/xla PR against a pytorch/pytorch PR or branch,
put the PR number or branch name in this file.
Example:
#32451
# or
my_awesome_branch # (must live in `pytorch/pytorch`)
In the case where the pytorch/pytorch PR also depends on the pytorch/xla PR, you will also need to update the https://github.com/pytorch/pytorch/blob/main/.github/ci_commit_pins/xla.txt to match the latest hash of your pytorch/xla PR. To be noted, the hash from a PR produced by a fork won't work in this case. Then you need to find someone from the pytorch/xla team to produe a branch PR for you.
