2016-01-20Merge branch 'js/fopen-harder'Libravatar Junio C Hamano1-1/+1
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}()Libravatar Junio C Hamano1-1/+1
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>

2015-10-16strbuf: make stripspace() part of strbufLibravatar Tobias Klauser1-3/+3
This function is also used in other builtins than stripspace, so it makes sense to have it in a more generic place. Since it operates on an strbuf and the function is declared in strbuf.h, move it to strbuf.c and add the corresponding prefix to its name, just like other API functions in the strbuf_* family. Also switch all current users of stripspace() to the new function name and keep a temporary wrapper inline function for any topic branches still using stripspace().

2015-08-31commit: don't rewrite shared index unnecessarilyLibravatar David Turner1-3/+1
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" filesLibravatar Jeff King1-16/+16
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 structLibravatar Jeff King1-2/+2
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_* variablesLibravatar Jeff King1-21/+5
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 templateLibravatar Jeff King1-9/+14
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 commentLibravatar Junio C Hamano1-16/+31
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>

While at it, swap two of the arguments in the function to put output arguments at the end. As a nice side effect, this ensures that we can catch callers that were unaware of the new API so they can be audited. Give the wrapper functions resolve_refdup and read_ref_full the same treatment for consistency.

2014-10-15refs.c: pass the ref log message to _create/delete/update instead of _commitLibravatar Ronnie Sahlberg1-2/+2
Change the ref transaction API so that we pass the reflog message to the create/delete/update functions instead of to ref_transaction_commit. This allows different reflog messages for each ref update in a multi-ref transaction.

2014-10-14color_parse: do not mention variable name in error messageLibravatar Jeff King1-2/+1
Originally the color-parsing function was used only for config variables. It made sense to pass the variable name so that the die() message could be something like: $ git -c color.branch.plain=bogus branch fatal: bad color value 'bogus' for variable 'color.branch.plain' These days we call it in other contexts, and the resulting error messages are a little confusing: $ git log --pretty='%C(bogus)' fatal: bad color value 'bogus' for variable '--pretty format' $ git config --get-color foo.bar bogus fatal: bad color value 'bogus' for variable 'command line' This patch teaches color_parse to complain only about the value, and then return an error code. Config callers can then propagate that up to the config parser, which mentions the variable name. Other callers can provide a custom message. After this patch these three cases now look like: $ git -c color.branch.plain=bogus branch error: invalid color value: bogus fatal: unable to parse 'color.branch.plain' from command-line config $ git log --pretty='%C(bogus)' error: invalid color value: bogus fatal: unable to parse --pretty format $ git config --get-color foo.bar bogus error: invalid color value: bogus fatal: unable to parse default color value Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-10-14pass config slots as pointers instead of offsetsLibravatar Jonathan Nieder1-10/+9
Many config-parsing helpers, like parse_branch_color_slot, take the name of a config variable and an offset to the "slot" name (e.g., "color.branch.plain" is passed along with "13" to effectively pass "plain"). This is leftover from the time that these functions would die() on error, and would want the full variable name for error reporting. These days they do not use the full variable name at all. Passing a single pointer to the slot name is more natural, and lets us more easily adjust the callers to use skip_prefix to avoid manually writing offset numbers. This is effectively a continuation of 9e1a5eb, which did the same for parse_diff_color_slot. This patch covers all of the remaining similar constructs.

2014-10-01lockfile.h: extract new header file for the functions in lockfile.cLibravatar Michael Haggerty1-0/+1
Move the interface declaration for the functions in lockfile.c from cache.h to a new file, lockfile.h. Add #includes where necessary (and remove some redundant includes of cache.h by files that already include builtin.h). Move the documentation of the lock_file state diagram from lockfile.c to the new header file. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-10-01lockfile: change lock_file::filename into a strbufLibravatar Michael Haggerty1-6/+6
For now, we still make sure to allocate at least PATH_MAX characters for the strbuf because resolve_symlink() doesn't know how to expand the space for its return value. (That will be fixed in a moment.) Another alternative would be to just use a strbuf as scratch space in lock_file() but then store a pointer to the naked string in struct lock_file. But lock_file objects are often reused. By reusing the same strbuf, we can avoid having to reallocate the string most times when a lock_file object is reused.

2014-10-01prepare_index(): declare return value to be (const char *)Libravatar Michael Haggerty1-2/+2
Declare the return value to be const to make it clear that we aren't giving callers permission to write over the string that it points at. (The return value is the filename field of a struct lock_file, which can be used by a signal handler at any time and therefore shouldn't be tampered with.)
