2016-07-28Merge branch 'js/find-commit-subject-ignore-leading-blanks' into maintJunio C Hamano
A helper function that takes the contents of a commit object and finds its subject line did not ignore leading blank lines, as is commonly done by other codepaths. Make it ignore leading blank lines to match. * js/find-commit-subject-ignore-leading-blanks: reset --hard: skip blank lines when reporting the commit subject sequencer: use skip_blank_lines() to find the commit subject commit -C: skip blank lines at the beginning of the message commit.c: make find_commit_subject() more robust pretty: make the skip_blank_lines() function public
2016-06-29commit -C: skip blank lines at the beginning of the messageJohannes Schindelin
Consistent with the pretty-printing machinery, we skip leading blank lines (if any) of existing commit messages. While Git itself only produces commit objects with a single empty line between commit header and commit message, it is legal to have more than one blank line (i.e. lines containing only white space, or no characters) at the beginning of the commit message, and the pretty-printing code already handles that.

2016-06-08add: add --chmod=+x / --chmod=-x optionsEdward Thomson
The executable bit will not be detected (and therefore will not be set) for paths in a repository with `core.filemode` set to false, though the users may still wish to add files as executable for compatibility with other users who _do_ have `core.filemode` functionality. For example, Windows users adding shell scripts may wish to add them as executable for compatibility with users on non-Windows. Although this can be done with a plumbing command (`git update-index --add --chmod=+x foo`), teaching the `git-add` command allows users to set a file executable with a command that they're already familiar with.

"git commit" misbehaved in a few minor ways when an empty message is given via -m '', all of which has been corrected. * ad/commit-have-m-option: commit: do not ignore an empty message given by -m '' commit: --amend -m '' silently fails to wipe message
2016-04-07commit: do not ignore an empty message given by -m ''Jeff King
When f9568530 (builtin-commit: resurrect behavior for multiple -m options, 2007-11-11) converted a "char *message" to "struct strbuf message" to hold the messages given with the "-m" option, it incorrectly changed the checks "did we get a message with the -m option?" to "is message.len 0?". Later, we noticed one breakage from this change and corrected it with 25206778 (commit: don't start editor if empty message is given with -m, 2013-05-25). However, "we got a message with -m, even though an empty one, so we shouldn't be launching an editor" was not the only breakage. * "git commit --amend -m '' --allow-empty", even though it looks strange, is a valid request to amend the commit to have no message at all. Due to the misdetection of the presence of -m on the command line, we ended up keeping the log messsage from the original commit. * "git commit -m "$msg" -F file" should be rejected whether $msg is an empty string or not, but due to the same bug, was not rejected when $msg is empty. * "git -c template=file -m "$msg"" should ignore the template even when $msg is empty, but it didn't and instead used the contents from the template file. Correct these by checking have_option_m, which the earlier 25206778 introduced to fix the same bug.

2016-02-25diff: activate diff.renames by defaultMatthieu Moy
Rename detection is a very convenient feature, and new users shouldn't have to dig in the documentation to benefit from it. Potential objections to activating rename detection are that it sometimes fail, and it is sometimes slow. But rename detection is already activated by default in several cases like "git status" and "git merge", so activating diff.renames does not fundamentally change the situation. When the rename detection fails, it now fails consistently between "git diff" and "git status". This setting does not affect plumbing commands, hence well-written scripts will not be affected.

2016-01-20Merge branch 'js/fopen-harder'Junio C Hamano
Some codepaths used fopen(3) when opening a fixed path in $GIT_DIR (e.g. COMMIT_EDITMSG) that is meant to be left after the command is done. This however did not work well if the repository is set to be shared with core.sharedRepository and the umask of the previous user is tighter. They have been made to work better by calling unlink(2) and retrying after fopen(3) fails with EPERM. * js/fopen-harder: Handle more file writes correctly in shared repos commit: allow editing the commit message even in shared repos
2016-01-15strbuf: introduce strbuf_getline_{lf,nul}()Junio C Hamano
The strbuf_getline() interface allows a byte other than LF or NUL as the line terminator, but this is only because I wrote these codepaths anticipating that there might be a value other than NUL and LF that could be useful when I introduced line_termination long time ago. No useful caller that uses other value has emerged. By now, it is clear that the interface is overly broad without a good reason. Many codepaths have hardcoded preference to read either LF terminated or NUL terminated records from their input, and then call strbuf_getline() with LF or NUL as the third parameter. This step introduces two thin wrappers around strbuf_getline(), namely, strbuf_getline_lf() and strbuf_getline_nul(), and mechanically rewrites these call sites to call either one of them. The changes contained in this patch are: * introduction of these two functions in strbuf.[ch] * mechanical conversion of all callers to strbuf_getline() with either '\n' or '\0' as the third parameter to instead call the respective thin wrapper. After this step, output from "git grep 'strbuf_getline('" would become a lot smaller. An interim goal of this series is to make this an empty set, so that we can have strbuf_getline_crlf() take over the shorter name strbuf_getline(). Signed-off-by: Junio C Hamano <gitster@pobox.com>

'dt/commit-preserve-base-index-upon-opportunistic-cache-tree-update' When re-priming the cache-tree opportunistically while committing the in-core index as-is, we mistakenly invalidated the in-core index too aggressively, causing the experimental split-index code to unnecessarily rewrite the on-disk index file(s). * dt/commit-preserve-base-index-upon-opportunistic-cache-tree-update: commit: don't rewrite shared index unnecessarily
2015-08-31commit: don't rewrite shared index unnecessarilyDavid Turner
Remove a cache invalidation which would cause the shared index to be rewritten on as-is commits. When the cache-tree has changed, we need to update it. But we don't necessarily need to update the shared index. So setting active_cache_changed to SOMETHING_CHANGED is unnecessary. Instead, we let update_main_cache_tree just update the CACHE_TREE_CHANGED bit. In order to test this, make test-dump-split-index not segfault on missing replace_bitmap/delete_bitmap. This new codepath is not called now that the test passes, but is necessary to avoid a segfault when the new test is run with the old builtin/commit.c code.

2015-08-10memoize common git-path "constant" filesJeff King
One of the most common uses of git_path() is to pass a constant, like git_path("MERGE_MSG"). This has two drawbacks: 1. The return value is a static buffer, and the lifetime is dependent on other calls to git_path, etc. 2. There's no compile-time checking of the pathname. This is OK for a one-off (after all, we have to spell it correctly at least once), but many of these constant strings appear throughout the code. This patch introduces a series of functions to "memoize" these strings, which are essentially globals for the lifetime of the program. We compute the value once, take ownership of the buffer, and return the cached value for subsequent calls. cache.h provides a helper macro for defining these functions as one-liners, and defines a few common ones for global use. Using a macro is a little bit gross, but it does nicely document the purpose of the functions. If we need to touch them all later (e.g., because we learned how to change the git_dir variable at runtime, and need to invalidate all of the stored values), it will be much easier to have the complete list. Note that the shared-global functions have separate, manual declarations. We could do something clever with the macros (e.g., expand it to a declaration in some places, and a declaration _and_ a definition in path.c). But there aren't that many, and it's probably better to stay away from too-magical macros. Likewise, if we abandon the C preprocessor in favor of generating these with a script, we could get much fancier. E.g., normalizing "FOO/BAR-BAZ" into "git_path_foo_bar_baz". But the small amount of saved typing is probably not worth the resulting confusion to readers who want to grep for the function's definition.

2015-06-29convert "enum date_mode" into a structJeff King
In preparation for adding date modes that may carry extra information beyond the mode itself, this patch converts the date_mode enum into a struct. Most of the conversion is fairly straightforward; we pass the struct as a pointer and dereference the type field where necessary. Locations that declare a date_mode can use a "{}" constructor. However, the tricky case is where we use the enum labels as constants, like: show_date(t, tz, DATE_NORMAL); Ideally we could say: show_date(t, tz, &{ DATE_NORMAL }); but of course C does not allow that. Likewise, we cannot cast the constant to a struct, because we need to pass an actual address. Our options are basically: 1. Manually add a "struct date_mode d = { DATE_NORMAL }" definition to each caller, and pass "&d". This makes the callers uglier, because they sometimes do not even have their own scope (e.g., they are inside a switch statement). 2. Provide a pre-made global "date_normal" struct that can be passed by address. We'd also need "date_rfc2822", "date_iso8601", and so forth. But at least the ugliness is defined in one place. 3. Provide a wrapper that generates the correct struct on the fly. The big downside is that we end up pointing to a single global, which makes our wrapper non-reentrant. But show_date is already not reentrant, so it does not matter. This patch implements 3, along with a minor macro to keep the size of the callers sane.

2014-12-11commit: always populate GIT_AUTHOR_* variablesJeff King
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.

2014-12-11commit: loosen ident checks when generating templateJeff King
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.

2014-10-28merge & sequencer: turn "Conflicts:" hint into a commentJunio C Hamano
Just like other hints such as "Changes to be committed" we show in the editor to remind the committer what paths were involved in the resulting commit to help improving their log message, this section is merely a reminder. Traditionally, it was not made into comments primarily because it has to be generated outside the wt-status infrastructure, and also because it was meant as a bit stronger reminder than the others (i.e. explaining how you resolved conflicts is much more important than mentioning what you did to every paths involved in the commit). But that still does not make this hint a part of the log message proper, and not showing it as a comment is inviting mistakes. Note that we still notice "Conflicts:" followed by list of indented pathnames as an old-style cruft and insert a new Signed-off-by: before it. This is so that "commit --amend -s" adds the new S-o-b at the right place when used on an older commit. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-10-28builtin/commit.c: extract ignore_non_trailer() helper functionJunio C Hamano
Extract a helper function from prepare_to_commit() to determine where to place a new Signed-off-by: line, which is essentially the true "end" of the log message, ignoring the trailing "Conflicts:" line and everything below it. The detection _should_ make sure the "Conflicts:" line it finds is truly the conflict hint block by checking everything that follows is a HT indented pathname to avoid false positive, but this logic will be revamped in a later patch to ignore comments and blanks anyway, so it is left as-is in this step.
