The error message from "git commit", when a non-existing author name was given as value to the "--author=" parameter, has been reworded to avoid misunderstanding. * mg/commit-author-no-match-malformed-message: commit: reword --author error message

"git blame HEAD -- missing" failed to correctly say "HEAD" when it tried to say "No such path 'missing' in HEAD". * jk/blame-commit-label: blame.c: fix garbled error message use xstrdup_or_null to replace ternary conditionals builtin/commit.c: use xstrdup_or_null instead of envdup builtin/apply.c: use xstrdup_or_null instead of null_strdup git-compat-util: add xstrdup_or_null helper

commit: reword --author error message

2015-01-27T03:57:12Z

If an --author argument is specified but does not contain a '>' then git tries to find the argument within the existing authors; and gives the error message "No existing author found with '%s'" if there is no match. This is confusing for users who try to specify a valid complete author name. Rename the error message to make it clearer that the failure has two reasons in this case. (This codepath is touched only when we know already that the argument cannot be a completely wellformed author ident.)

builtin/commit.c: use xstrdup_or_null instead of envdup

2015-01-13T18:03:40Z

The only reason for envdup to be its own function is that we have to save the result in a temporary string. With xstrdup_or_null, we can feed the result of getenv() directly. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

commit: always populate GIT_AUTHOR_* variables

2014-12-11T23:34:37Z

To figure out the author ident for a commit, we call determine_author_info(). This function collects information from the environment, other commits (in the case of "--amend" or "-c/-C"), and the "--author" option. It then uses fmt_ident to generate the final ident string that goes into the commit object. fmt_ident is therefore responsible for any quality or validation checks on what is allowed to go into a commit. Before returning, though, we call split_ident_line on the result, and feed the individual components to hooks via the GIT_AUTHOR_* variables. Furthermore, we do extra validation by feeding the split to sane_ident_split(), which is pickier than fmt_ident (in particular, it will complain about an empty email field). If this parsing or validation fails, we skip updating the environment variables. This is bad, because it means that hooks may silently see a different ident than what we are putting into the commit. We should drop the extra sane_ident_split checks entirely, and take whatever fmt_ident has fed us (and what will go into the commit object). If parsing fails, we should actually abort here rather than continuing (and feeding the hooks bogus data). However, split_ident_line should never fail here. The ident was just generated by fmt_ident, so we know that it's sane. We can use assert_split_ident to double-check this. Note that we also teach that assertion to check that we found a date (it always should, but until now, no caller cared whether we found a date or not). Checking the return value of sane_ident_split is enough to ensure we have the name/email pointers set, and checking date_begin is enough to know that all of the date/tz variables are set.

commit: loosen ident checks when generating template

2014-12-11T23:34:35Z

When we generate the commit-message template, we try to report an author or committer ident that will be of interest to the user: an author that does not match the committer, or a committer that was auto-configured. When doing so, if we encounter what we consider to be a bogus ident, we immediately die. This is a bad idea, because our use of the idents here is purely informational. Any ident rules should be enforced elsewhere, because commits that do not invoke the editor will not even hit this code path (e.g., "git commit -mfoo" would work, but "git commit" would not). So at best, we are redundant with other checks, and at worse, we actively prevent commits that should otherwise be allowed. We should therefore do the minimal parsing we can to get a value and not do any validation (i.e., drop the call to sane_ident_split()). In theory we could notice when even our minimal parsing fails to work, and do the sane thing for each check (e.g., if we have an author but can't parse the committer, assume they are different and print the author). But we can actually simplify this even further. We know that the author and committer strings we are parsing have been generated by us earlier in the program, and therefore they must be parseable. We could just call split_ident_line without even checking its return value, knowing that it will put _something_ in the name/mail fields. Of course, to protect ourselves against future changes to the code, it makes sense to turn this into an assert, so we are not surprised if our assumption fails.
