This was a gotcha. macOS is usually built on top of a case-insensitive filesystem, where linux is not.

It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging. If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing.If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group. |

so (?i) is the case insensitive part? Is the whole match insensitive?

yep, we might want to consider making every line implicitly case-insensitive. we'll see if this becomes a reoccurring pain.
The diff on the LICENSE file is printed out with no commentary. I can expand on it. |
Thoughts on putting the new computed file in the logs directory that gets retained? @matanlurey might remember how to do that. |
It looks like the logs are already being saved: https://ci.chromium.org/ui/p/flutter/builders/try/Linux%20linux_license/35497/overview If you follow the link though the only thing that seems saved is noop.txt. Did we use to save logs then just shunt in noop.txt? |
@zanderso I added a more helpful failure message. |
|
Not sure if this would help, but my thinking was to save the new license file to the persistent logs directory. Downloading that file and adding it to the PR might be easier than copy-pasting the diff out of logs and applying it as a patch. Not as part of this PR, but if that's in improvement, it might be easier to do while we're thinking about it. |
Another thought,
Definitely, if the diff is big. For small changes it will be about the same workflow. But execution time is still 30s to 60s, downloading a file might save you a bit of time, but not a huge difference. |
|
This can go stale so I'm going to land this as is and we can address the logging problem in a future PR once we hear back from Matan. It seems stdout logging is sufficient for now. |
