Change to content hash for RN canary VERSION strings #28582

kassens · 2024-03-18T23:45:46Z

With this change, the different files in RN will have different hashes. This replaces the git hash and means that the file content (including version) is only updated when the rest of the file content actually changes. This should remove "noop" changes that need to be synced that only update the version string.

A difference to the www implementation here is (and I'd be looking at updating www as well if this lands well) that each file has an individual hash instead of a combined content hash. This further reduces the number of updated files and I couldn't find a reason we need to have these in sync. The best I can gather is that this hash is used so folks don't directly compare version string and make future updates harder.

This seems fine if it's only updating files that are synced to Meta, rather than files used in OSS. Hard to tell from the code if that's strictly the case.

LGTM, let's just follow up to confirm it doesn't impact the OSS files

In facebook#28582 I missed that experimental files have a copy of this build function setting the version strings.

Also apply content hash for experimental files In #28582 I missed that experimental files have a copy of this build function setting the version strings.

With this change, the different files in RN will have *different* hashes. This replaces the git hash and means that the file content (including version) is only updated when the rest of the file content actually changes. This should remove "noop" changes that need to be synced that only update the version string. A difference to the www implementation here is (and I'd be looking at updating www as well if this lands well) that each file has an individual hash instead of a combined content hash. This further reduces the number of updated files and I couldn't find a reason we need to have these in sync. The best I can gather is that this hash is used so folks don't directly compare version string and make future updates harder.

…k#28582)" This reverts commit cb076b5.

#29236 caused issues for internal syncs at Meta, because we were computing version numbers using file hashes (to eliminate "no-op" internal sync commits). The problem is that since version numbers may not be consistent across synced files (e.g. if some files have not changed in recent commits), the newly introduced version mismatch check fails. There's some more work that needs to be done here to restore the benefits of file-specific hashing, but for now this simply reverts the content hash changes from the following PRs: - #28633 (95319ab) - #28590 (37676ab) - #28582 (cb076b5) - #26734 (5dd90c5) - #26331 (3cad3a5)
