It's not only about the fact that the commit message for a one char change is about a page long. It's about that all the information in that page long commit message is a useful information
There is so much superfluous cruft in the message.
Listing the error, and the fix, would give exactly as much context for the next person to run into this issue.
If your goal to explain the process to find similar cases, just a couple more lines would have done just as well:
-
Fixes case where `bundle exec rake` would fail with error message:
ArgumentError: invalid byte sequence in US-ASCII
This is caused by the presence of non-ASCII characters in files.
The following command was used to find files with non-ASCII characters:
`find modules -type f -exec file --mime {} \+ | grep utf`
Running `iconv -f UTF8 -t US-ASCII` on listed files will show the exact location of offending characters.
-
No long winded exposition, no extremely case specific program output (including current machine's name...)
I’m not saying this is the worst commit message ever, and I’d appreciate the intention if I came across it, but if you’re caring enough to give this much context, you can save both yourself, and the next person to look for your message, some cognitive load by sticking to what’s needed.
-
And if you’re wondering how to decide “what is needed”, it varies, but I think a good rule of thumb is: ask yourself how one would find this commit message
What would someone grep for in git's history if they came across this? And if they found it, what information answers their query?
They’re likely to search the command that is failing, and the error.
The answer to that query is, what causes the command to error out, and how to find cases of that cause.
They’re not going to search for the program output of find, or iconv, not going to search for the exact file you were modifying when this happened, or the fixes you tried that didn’t work.
I mean, you're right, but I don't think that's time well spent. This is a commit message, not a blog post. Writing concisely is hard and time consuming.
This was probably written in stream-of-consciousness fashion which strikes a nice balance between time invested and possible future usefulness (if any). I mean, the commit might be useful in the future, but there's also a reasonable chance that nobody except the reviewer of the PR is ever going to read that commit message. (If the OP hadn't blogged about it)
If I come across an error and it takes two commands to fix it, my immediate intuition is a commit message with... the error and the two commands. And that’s extremely quick to write...
It’s definitely not “let me write a detailed account of the last hour of my life”... that immediately feels like it will take much longer
Also to be clear, the rule of thumb I mention is not about “what should you think about, then write down”
It’s a filter on what you were already about to invest effort in writing down.
If you feel like an even shorter message is good enough, that’s great.
Just realize sometimes less is more...
If the information took you a great deal of effort to get, that suggests it may be valuable to share. That may not be the right time to attempt to cut out some of that information for brevity, especially if you don't know what the future reader of the message might need to know.
I think you edited this in after my reply:
> If the information took you a great deal of effort to get, that suggests it may be valuable to share.
I think this is the core of where we disagree. I often spend insane amounts of time debugging something, only to find the solution was quite simple and unrelated to what I tried.
Often the amount of time you spent debugging is because the search space for your solution was unbounded, not because each step you took was particularly relevant to the actual solution.
To me a commit message should be able hopefully narrowing that search space, not documenting the original unbounded one.
I've read many commit messages with too little detail, and zero with too much detail. (I have read code with too many comments, but it's rare; I've never once read a commit message that made me think "too much detail".) I'm sure it's possible, but on balance I prefer to cultivate instincts of "document anything that was hard to learn" and "in the moment, prefer to over-document rather than under-document".
I appreciate the intention and wouldn’t complain, it’s just if you care enough to write so much, save yourself sometime and the next person to read it some effort by being a little more concise.
Commit messages are like naming things, there’s no right way, but the more you try to do it “right” the more “right” you get.
If you just throw your hands up and say “I’m goin to vomit our every thought I had working on this”, sure it won’t kill anyone and it’s preferable to always writing nothing (that’s kind of obvious...), but you’ll never get to the point where writing even somewhat balanced messages is comfortable
I definitely agree with BoorishBears - too much unnecessary details in this commit message. Of course it is much more preferable than "Fix template", "Fix utf8" or "fix" which is all too common. But if someone spent 1 hour fixing a problem and then probably 5-10 minutes working on the message then adding 5 minutes to make the message concise should not be a big deal, right? (Who am I kidding ;-))
We use Gerrit at my company, so pushing the change is just a first step. I routinely read my commits after they are pushed for review and many times there are one or more additional changesets because I thought I found something worthy to add to the commit message.
