Thread: Template for commit messages
There has been a request in the FOSDEM developers meeting that committers use a more consistent format for commit messages. This is the format I use: -- email subject limit ------------------------------------------- gitweb summary limit --------------------------ReportbyPatch byReviewed byBackpatch through The dashed lines are used to specify a target length for the summary line and are automatically removed before the commit message is posted. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + As you are, so once was I.

Good idea. :-) Updated template:
-- email subject limit -----------------------------------------
-- gitweb summary limit --------------------------
Reported-by:

Patch-by:
Reviewed-by:
Backpatch through:
I had to make up "Patch-by:" as it wasn't listed.
The original format uses the author for that (author != committer in git), but that changes how we work a bit more. I'd be happy to just clal it "Author" rather than "Patch-by".
I also suggest a - in "Backpatch-through:" -- since all the others are intentionally mad ewithout a space, I assume that's for easier parsing.
They also had tested-by, it might be an idea to include that as well?

One of the things I like about the current free-form approach is that you can indicate nuances, like: Person X reviewed an earlier version of this patch that was a lot different than this one. Person X reviewed this patch but didn't totally endorse it. Person X wrote the documentation for the patch, but none of the code. Person X wrote the vast bulk of this patch, even though there are some other authors. Should I just abandon the idea of trying to capture those details, or does this format contemplate a way to include them? (Also an important question: Has Tom agreed to use this new format? Because I think that anything the rest of agree on that he's not prepared to endorse is not going to have much value.) -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company

FWIW, I'm a bit suspicious of the idea that we need to make the commit messages automated-tool-friendly. What tools are there that would need to extract this info, and would we trust them if they didn't understand "nuances"? I'm on board with Bruce's template as being a checklist of points to be sure to cover when composing a commit message. I'm not sure we need fixed-format rules. regards, tom lane

Apologies, I was kidding actually -- I don't think we should list people on patches just because they provided some input in the thread, but people that actually reviewed the patch. Otherwise we risk diluting the list in the release notes (or wherever it is that we end up crediting reviewers/contributors), which is also undesirable. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services

It's nice to capture the nuance, but the nuance is going to get flattened out anyway when the release notes are created. If we all agree to use a fixed format, then a bunch of work there that probably has to be done manually can be automated. However, if we all agree to use a fixed format except for you, we might as well just forget the whole thing, because the percentage of commits that are done by you is quite high. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company

I'm not sure we need > fixed-format rules. I've been asking for them for years so I can spend my time on the PostgreSQL Weekly News more efficiently. Maybe it's more efficient for me to do this arranging than for each committer to do it. I'd like to imagine that committers are in a better position than I to summarize their work. Whatever we decide on here, I'd really appreciate it if every patch sent to the list came with a sentence describing what that version of it does, as scope drift frequently makes Subject: lines completely wrong. While I'm at it, I'd like to thank Andres Freund, Peter Geoghegan, and Robert Haas in particular for making a habit of writing detailed summaries and splitting patches into logical chunks. All errors in the PostgreSQL Weekly News are mine, but a little organization like theirs would go a very long way, and not just for me.

I don't have a particular issue with it, but would like whatever template is decided upon to be included in our git repo and then we should be able to make it the template that's opened up when people go to commit pretty easily.

OK, but keep in mind whatever script committers user should remove tags that are empty after exiting the editor.

Having a decent script would work too, of course... but I have to admit that I've not tried having a script modify my commit messages right before they're committed and, well, it'd take a bit for me to be comfortable with it. No one wants garbled commit messages from a script that went awry. ;) Thanks! Stephen

I have no prejudice in this area, other than one in favor of any rules being fairly precise. As for nuances, I guess they can be specified in the commit message. The one thing I do find annoying from time to time is the limit on subject size. Sometimes it's very difficult to be sufficiently communicative in, say, 50 characters. cheers andrew

So the committer would need to remove the # and then fill in the data for the field. git-commit(1) says: -t <file>, --template=<file> When editing the commit message, start the editor with the contents in the given file. The commit.template configuration variable is often used to give this option implicitly to thecommand. This mechanism can be used by projects that want to guide participants with some hints on whatto write in the message in what order. If the user exits the editor without editing the message, the commit is aborted. This has no effect when a message is given by other means, e.g. with the -m or -F options. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services

I'm not particularly impressed by this argument --- as someone who regularly prepares release notes, I see exactly zero value in this to me. I'm willing to go along with it if there's consensus, but the argument that "Foo: Bar" format has more value than free-form hasn't actually been made in any form that withstands any skepticism. In any case, agreeing on a set of "Foo:" keywords isn't nearly enough to allow any useful automated processing. You have to standardize the "Bar" part as well, and that hasn't been addressed at all. Some example questions: In "Bug:", bug number with or without "#"? What format to use if there's more than one related bug? In headers referring to people: name? email? both? what if we have incomplete information (not unusual in bug reports)? what about referencing multiple people in same header? what can we do to avoid variant spellings in different commit messages? In "Backpatch-through:", how are we to indicate version numbers exactly? what about special cases such as a patch applied only to older branches? And perhaps most importantly, why are we bothering with that at all when git can tell us that much more reliably? (Personally, I only bother with mentioning this in the commit message to the extent that I'm explaining *why* I patched back so far and no further. Which I think is useful information that a "backpatch-through: N.N" kind of entry would entirely fail to capture.) regards, tom lane

Well, this gets at one of the problems here, which is that you can't fix a commit message once the commit has been pushed. So even if we all agreed in principle to a standard format, it's not clear that you could enforce compliance with that format to a degree sufficient to make machine-parseability a reality. But let's say you could somehow make it so that every commit message was machine-parseable. Then you could write a script which went through the commit log since the branch point for the prior release and extracted every name listed as a reviewer and printed them all out. Then you could put that in the release notes or on the project web site someplace and say "The PostgreSQL Project thanks the following list of people for reviewing patches during the 9.23 release cycle". Doing that same thing without machine-parseable commit messages can of course also be done, but it's going to require somebody to manually review every commit, which is a lot more work. Similarly, you could do write a script to do things like "show me all patches with person X as an author". Right now that's actually kind of hard to do, especially if that author happens to be a committer. Or you could write a script to print out all commits from the last week in the format: COMMITTER committed a patch from AUTHOR to do SUMMARY, and then you could stick that into PWN, again instead of having to do it by manually reviewing the commit message. I'm not sure that those benefits are sufficient to justify the hassle of trying to make a fixed template work. But I think it's a little strange to hear a bunch of people whose develop the world's most advanced open source relational database system argue that structured data is an intrinsically unused thing to have, and therefore we should just store all of our information freeform in one very wide text column. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company

Yes, I'm aware that this is a problem. I tried to raise the point that we could use "git notes" to provide additional information after the fact but was quickly made to shut up before it could be recorded in the minutes. If we were to adopt git notes or a similar system(*), we could use those as a mechanism to install the machine-parseable data for each commit, which I think fixes all the problems you point out.

Yeah. It's a crazy thought, but it's almost like this databasey thing was designed precisely for the purpose of allowing people to structure their data in relational ways and then interact with it in convenient fashion. Personally, I think that if we had a database of commit metadata, we could use that to do all sorts of interesting reporting. I don't think any of that reporting is absolutely necessary for the survival of the project, but sometimes things that aren't absolutely necessary can still be awfully nice. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company

constructed something a wee bit too fragile.
A thing plausible instead is to collect the authoritative-at-commit-time
message information into an external system (hey, I wonder if anyone
has some sort of structured data store implemented that could be
good at this!), and then have a way to feed additional information into
that system that would become the authoritative source for any
requirements for the extra metadata.
That, of course, smells like a database that draws metadata from git,
and augments with further streams of inputs. There is certainly
something problematic about assuming that we can *always* get
supplementary data. Begs the question of how we shame people
into going back and filling the blanks we wanted filled.
It seems foolish to me to imagine that we can ensure that the
data *always* arrives at commit time; any laziness there represents
a permanent "data fault"; making it asynchronous shifts the problem
to a different spot. I suspect we can only approach success on it,
and get *partial* metadata, at best. If it's enough better than nothing,
then maybe that's good enough. And I'll bet that the Commitfest
database already contains a lot of the data desired to fill blanks...
Further, if the point is to encourage reviews by making sure credit
(and hence data to support GIVING credit) is given, then it is not
inapropos for those keen on receiving credit to be responsible for
marking off the patches they know they contributed to. That's
less fragile than expecting all credit to be attached by the
committer at commit time.

We want *some* patch reviewers and beta testers. We don't really care what's their motivation, as long as their do their thing. The motivating factor is supposed to be getting credit -- not in the commit messages (because other people don't look at those) but having their names appear in the release notes. > >One of the offers is to credit them (I'm not exactly clear > >on what is the group to benefit from this, but the phrasing used in the > >meeting was "contributors to the release") by having a section somewhere > >in the release notes with a list of their names. > > I can see this as being a nice thing but knowing that someone is a > contributor isn't hard.

It's not obvious, which is why this is being discussed at all, and the contributor list in the website is useless for the purposes at hand. And it is hard, which is why the issue was raised in the first place -- heck, when this was mentioned, somebody said "but we would have to wait until 9.7 because we don't have that information in existing commit messages in 9.6 already" (he was promptly made to shut up, because most if not all committers are already crediting reviewers in their commit messages and we don't want to wait *two years* to implement this idea.) > >So the problem, of course, is collating that list of names, and the > >point of having a commit template is to have a single, complete source > >of truth from where to extract the info. > > I think the problem is that we think that this is somehow going to allure > more people.

I'm not sure what's your point here, but the release notes are going to list individuals, not companies.

Sorry for little late.
Can we add Severity level of patch? with only three levels as (High, Moderate, Low)
Many of our customers might not understand overall important of patch.
If we add this people/customers can choose patch is important for them or not.
Other than Author and hackers can not easily understand overall importance of patch.
Please consider if you feel it is important to add this parameter in commit message format.

+1. Having to look at the archives to find to which discussion a
commit is attached is a pain. Last time this was suggested though
there were concerns regarding the 72-80 character limit per line in a
commit message.
Let's just assume that we can fix that part. As in, we can expose either an internal db id or a short hash or something, from the archives server. We could then have that visible/linkable directly on the archives page, and one could copy/paste that link into the commit message. That way we can avoid the long messageids.

That seems like a misdirect. The limit is there to keep things readable, not because there's a hard technical limit. So if a messageid is longer, it doesn't have much consequence. Andres

I also quite often look at a commit message, and then hunt the "per discussion". A message-id would save some time there. I've seen you add annotations like that to your commits, which is nice. I'll start doing that myself. You've used the "Discussion: <message-id>" format for that, so I'll go with that too. (Even if the message-id is given in free-form in the paragraphs, that's helpful, but might as well use a fixed form.) And that's a proposal that's not "we must all do it or it's useless". If half of commit messages include that, then hunting the "per discussion" for those commits becomes easier, and the rest are the same as now. - Heikki

Raw messageids have the big big advantage that you can get them locally in your mailreader, and you can dereference them locally... I type esc-X id:$id<enter> and 20ms later I have the whole thread open. Maybe I just travel too much, but travel time is often long and uninterrupted and thus pretty nice to work on patches. I don't really see the problem, even with gmail style messageids Discussion: CABUevEz_UJA0ddrW7apjh3Nm4p0KghwOPm0WPW4Mh_gT2-nRJw@mail.gmail.com isn't that bad. Andres

I don't travel as much as you or Magnus do (!) but I do offline work a lot, so I appreciate full message-ids. > I don't really see the problem, even with gmail style messageids > Discussion: CABUevEz_UJA0ddrW7apjh3Nm4p0KghwOPm0WPW4Mh_gT2-nRJw@mail.gmail.com > isn't that bad. Yes, yes, I prefer to use the full URL because then a machine can tell whether it's an email address and not a message-id, which is useful for mangling addresses while at the same time not mangling message-ids. But I'm not going to force that on anybody. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services

Raw messageids have the big big advantage that you can get them locally
in your mailreader, and you can dereference them locally... I type
esc-X id:$id<enter> and 20ms later I have the whole thread open. Maybe
I just travel too much, but travel time is often long and uninterrupted
and thus pretty nice to work on patches.
If it was a short hash of the same thing, you could equally find them locally though, couldn't you?
I don't really see the problem, even with gmail style messageids

If people don't actually have a problem with it, that of course makes it even easier :)
