It was suggested in a dev.planning thread that we use a precommit hook on hg.mozilla.org in order to force correctly formatted commit comments.  We probably need multiple regex's to cover various possible comments.

Here are some crude examples:

For normal bugs:

/^Bug\s+\d+\s+-\s+(.*)\s*r=[^\s]+(\s+sr=[^\s]+)?(\s+a\d+=[^\s]+)?(\(NPOTB\))?$/

Note that the summary field is intentionally optional for security sensitive bugs.

Backouts:

/^Backed out changeset [\da-f]{12}.*\b[bB]ug\s+\d+/
/^Backout\s+[Bb]ug\s+\d+/

Merges:

/^Merge /

Custom messages for things not covered about (example: branching):

/\(xxx\)$/

I'm not sure what to replace xxx above with.  :-)
Ah, and also:

/bustage fix/i
This seems really hard to get right with the wide variety of things people wind up committing. I'm open to ideas though! It would be interesting to take any proposed set of regexes and run them against the history of m-c commits (at least back to the end of cvs mirroring) and see if there are exceptions that we'd need to handle.
Are we in particular only requiring these rules on the last commit of each push? How would you allow e.g. tracemonkey->m-c merges for which a bug# and review annotations are irrelevant (because they are contained within the original commit when it was pushed to TM)?

If we go down the route of enforcing a specific style of comments, we need to make sure the release automation scripts either follow the enforced style or to exclude what that does in the hook.
CCing bhearsum, who probably knows those scripts best - Ben, note that there's no decision on doing this yet, we just shouldn't be caught off-guard if it's actually done.
Yeah, I'm watching this.

Man, do we assign a prize for Most Useless Bug yet? ;-)
It's certainly not useless. There have been plenty of patches committed without bug numbers or reviewers specified (or either, there are a few commits with just the MQ patch notation in them).
Hopefully the warning that hg 1.3 throws when you qfinish a patch that has no message will start to help there soon.

We're going to proceed with the plan Jesse laid out in bug 660705 comment 0.

If we're going with the one-off excluding of certain users for releng purposes (which I still find too fragile) then we need to add at least seabld and (I think) tbirdbld as well.

No, it was done with an awfully restrictive 2 weeks.

Which is not all that much data, in reality.

It also misses the release-repo's which might matter for sake of argument here.

I propose:

pull m-c, m-aurora, m-beta, m-release, m-1.9.2, m-1.9.1, and m-1.9.0 to the same local repo.

Run this test across at least a year of data, to see if we need to tweak the regex's before we actually deploy this hook.

Whatever we come up with, we're bound to forget a case.  We can always modify the hook, and the hook includes switch off triggers such as "no bug" anyways.

Compared to my previous guesswork, it is!

We don't need to deploy this hook on release repos.

I'm not sure what the merit of doing this would be.  The next person could ask for 13 months of data.  There is no reason for us to assume that 1 year is enough.

We can always modify the hook yes, but we must (a) modify, (b) get review, (c) test, (d) get IT to deploy

Which has a definite turnaround involved, which could unnecessarily block someones work (especially someone not great with hg to know about the qimport -r tip trick)

It is, but c#2 mentioned all of hg csets, and you implied that was done. I was just pointing out it was not.

Any repo that mirrors m-c, should have the m-c type hooks deployed. There is the SAME issue with bisecting in release repos as beta/aurora/etc. repos. and we already decided in the thread that we want this everywhere there is a m-c-based repo.

I don't think even all of hg would be enough [to make this perfect] since there will always be cases we miss. I do however, feel 2 weeks is FAR FAR too few to have a reasonable reliability involved in getting this deployed. but for my proposal of 1 year, I weighed the aspects of time vs data in my mind on what would produce a useable set of data that we can skim for patterns that could/should change the above regex's.

I don't think we need to deeply investigate why a certain cset was a MQ header, etc. but just a look around of "is this rejected cset message one that should have matched but doesn't"
To make it more clear, I have no objection for you to convince Jesse to run his analysis on a larger chunk of time.  I just think that it won't catch all cases, but since you seem to know that already, I'll stop being grumpy about it.  :-)

I'll add "cset". I've also added an allowance for plurals.

> * Starts with (back out|backing out|backed out|backout)( bug | b=)\d{1,9}

Isn't this redundant with allowing commits that have bug numbers?

That's one solution, but I like Ehsan's better: allow the tip to contain a magic phrase that overrides the hook for the rest of the commit.  This allows new experimental branches to operate in experimental mode until they prepare to merge.  Once a branch is no longer experimental (e.g. it has merged to mozilla-central) it should have the hook enabled.

> I expect us to match a valid rev here without fail!

In practice, we use 12-digit or 40-digit rev ids, so requiring 12+ digits shouldn't cause problems.  Accepting shorter ones would make future conflicts likely.

That magic phrase thing would also allow us to get rid of those one-off users for releng, if we'd just patch the comments of releng commits to use that (like we already do with the |CLOSED TREE a=release| in those).

Comment 24

RelEng bots could use "no bug", but they wouldn't be able to use the other magic phrase, which only applies to the *other* commits in a push.

Comment 25

Actually, "no bug" probably makes really sense there in any case. We should file a bug that they should add that.

For the record, I'd like the "specific user" stuff baked in from the start (if its not too complex) to make sure that we don't have a block on this from multiple sources. (such as all the various releng teams updating repo's to production with that magic)
(In reply to comment #26)
(hit submit too early)...

The specific user stuff we can drop at a point in time later when all releng users do "no bug" like we think makes the most sense.
Jesse,

I just caught/remember another case that I think warrants mention:

http://hg.mozilla.org/releases/mozilla-release/rev/921e788dbe19

|Automated blocklist update from host moz2-linux-slave34|

Do we want to (a) allow that message as it stands, (b) anotate as "no bug", (c) Enforce doing this with bugs, (d) something else. or (e) one of a or b with a followup discussion to decide a better way forward?

For one thing, it's "ffxbld" so triggers the "some users are special" clause, but for the other, I think it should have "no bug".

Fewer than 4% of commits rejected. Most were mistakes or bustage fixes.

You also can add "no bug" to the comment - the hook accepts this as it's clear you didn't inadvertently forget to add a bug number ;-)

Is this just to make sure we don't reject pushes from repos merging to m-c after the hook was enabled?

Yes, along with the other direction (m-c merging to other repos).

Merge changesets are also used for other things.  Commits don't carry metadata stating which repositories they have been pushed to, and trying to figure that out while running a hook seems difficult.

It's primarily for allowing an experimental-rapid-informal branch to become a serious project branch once it becomes clear that the experiment is likely to succeed and merge to central.  We could force type inference to rewrite its commit history, but that would cause a bucket of other problems.
Thanks for the explanations. If you address the other comments I added, I'm fine with this landing and being enabled.

Jesse already thought of that, his patch implements that.
What's about rs=, this has been used in the tracemonkey branch for "no bug" stuff.

This should have some extra comment. And why isn't this in okCommit?
It looks like the triple quotes were to avoid having to double-escape backslashes, maybe.  If so, Python has raw strings for this purpose:

  r"a\b" == "a\\b"
I poked Jesse about this in IRC a day or two ago, but I sometimes have a problem pushing patches which I haven't updated with r= information, and I mark all patches that aren't complete or haven't been reviewed with "NOT REVIEWED YET".  Very rarely I forget to update the commit message with the proper r= information prior to pushing -- once in January 2009, and twice again this month (!).  Adding some sort of reasonably sensible phrase that would prevent a commit from happening would be nice, so I don't forget to add that r= information again.
What is the status here?

I think it has to be numeric because it gets compared with numeric dates from hg.

Seemed less error-prone than using r"x", but I could switch.

Dunno. But it's possible to get past the try hook with just "try: "!

So Jesse was a bit short on time, so i asked him to finish this. I fixed the nits i had + the comments by Jesse.

I'm going to write wiki entry about what this patch changed. I also would like to propose, some standardized for "normal" commits, before writing this. Furthermore i would like to like to make some more useful hooks, like disallowing trailing whitespace, checking that the bug id exists etc.
Jesse suggested adding a feature so you could run this hook locally, and it would warn you about bad commits. Some of the proposals above would be nice to have for local commits in case we don't want to run them on the server.

This needs some tinkering (at least for me)
