[HACKERS] Easy way to verify gitignore files?
It's not hard to tell if we're missing a file that ought to be listed in .gitignore --- git status will find that problem soon enough. However, it seems that git isn't so willing to tell you about gitignore patterns that cover too much, i.e. match files that are already in the repository. I found out by accident that you will only hear about this when you try to "git add" such a file after changing it. This seems pretty dangerous, especially for people who are willing to rely on "git commit -a" :-( Is there any automated sanity check that we can run to find this sort of problem? I suspect that we probably have got some errors in the .gitignore files, particularly in the back branches, and it would be nice to find them now before they get in the way of normal development. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

No doubt, but I was hoping somebody already had. In particular, it'd be best if one could use git's own logic for matching .gitignores, rather than reimplementing it in a way that might or might not behave quite the same. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

If .gitignore specifies a pattern that matches something that's already in the repository, that specification is itself ignored, and the file is treated like any other file. > This seems pretty dangerous, especially for people who are willing to > rely on "git commit -a" :-( There is no danger. "git commit -a" will commit changes to files that match .gitignore but are already in the repository. (I vaguely remember that there were bugs in this regard in old versions of git, but it's not a problem with any recent version AFAIK.) -- ams -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

Once a file is tracked by git, you can try to gitignore it all you like, it won't have any effect.

I can demonstrate that this is not so. Try a "git add" on such a file. It fails --- at least it does with the version of git currently in Fedora 13. You get some nasty warning about how there's a conflicting .gitignore pattern and you have to use -f if you want to add. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

What version do you use? If I try to add an untracked file which is already ignored, then I get the warning. -- ams $ git init a; cd a Initialized empty Git repository in /home/ams/a/.git/ $ echo foo > a; git add a; git commit -m 1 [master (root-commit) 0031fcb] 1 1 files changed, 1 insertions(+), 0 deletions(-) create mode 100644 a $ echo a > .gitignore; git add .gitignore; git commit -m 2 [master ed019e5] 2 1 files changed, 1 insertions(+), 0 deletions(-) create mode 100644 .gitignore $ echo bar > a; git add a; git commit -m 3 [master 19e5d2a] 3 1 files changed, 1 insertions(+), 1 deletions(-) $ echo baz > a; git commit -a -m 4 [master 73da20a] 4 1 files changed, 1 insertions(+), 1 deletions(-) -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
