2015-08-20log: show merge commit when --cc is givenLibravatar Junio C Hamano1-0/+4
We defaulted to ignoring merge diffs because long long ago, in a galaxy far away, we didn't have a great way to show the diffs. The whole "--cc" option goes back to January '06 and commit d8f4790e6fe7 ("diff-tree --cc: denser combined diff output for a merge commit"). And before that option - so for about 8 months - we had no good way to show the diffs of merges in a good dense way. So the whole "don't show diffs for merges by default" actually made a lot of sense originally, because our merge diffs were not very useful. And this was carried forward to this day. "git log --cc" still ignores merge commits, and you need to say "git log -m --cc" to view a sensible rendition of merge and non-merge commits, even with the previous change to make "--cc" imply "-p". Teach "git log" that "--cc" means the user wants to see interesting changes in merge commits by turning "-m" on. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-08-20log: when --cc is given, default to -p unless told otherwiseLibravatar Junio C Hamano1-0/+4
The "--cc" option to "git log" is clearly a request to show some sort of combined diff (be it --patch or --raw), but traditionally we required the command line to explicitly ask for "git log -p --cc". Teach the command line parser to treat a lone "--cc" as if the user specified "-p --cc". Formats that do ask for other forms of diff output, e.g. "log --raw --cc", are not overriden.

2015-08-20log: rename "tweak" helpersLibravatar Junio C Hamano1-5/+6
The revision walking API allows the callers to tweak its configuration at the last minute, immediately after all the revision and pathspec parameters are parsed from the command line but before the default actions are decided based on them, by defining a "tweak" callback function when calling setup_revisions(). Traditionally, this facility was used by "git show" to turn on the patch output "-p" by default when no diff output option (e.g. "--raw" or "-s" to squelch the output altogether) is given on the command line, and further give dense combined diffs "--cc" for merge commits when no option to countermand it (e.g. "-m" to show pairwise patches). Recently, "git log" started using the same facility, but we named the callback function "default_follow_tweak()", as if the only kind of tweaking we would want for "git log" will forever be limited to turning "--follow" on by default when told by a configuration variable. That was myopic. Rename it to more generic name "log_setup_revisions_tweak()", and match the one used by show "show_setup_revisions_tweak()". Signed-off-by: Junio C Hamano <gitster@pobox.com>

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.

2015-06-01format-patch: do not feed tags to clear_commit_marks()Libravatar Junio C Hamano1-6/+6
"git format-patch --ignore-if-in-upstream A..B", when either A or B is a tag, failed miserably. This is because the code passes the tips it used for traversal to clear_commit_marks(), after running a temporary revision traversal to enumerate the commits on both branches to find if they have commits that make equivalent changes. The revision traversal machinery knows how to enumerate commits reachable starting from a tag, but clear_commit_marks() wants to take nothing but a commit. In the longer term, it might be a more correct fix to teach clear_commit_marks() to do the same "committish to commit" dereferencing that is done in the revision traversal machinery, but for now this fix should suffice.

2015-05-21remote.c: report specific errors from branch_get_upstreamLibravatar Jeff King1-1/+1
When the previous commit introduced the branch_get_upstream helper, there was one call-site that could not be converted: the one in sha1_name.c, which gives detailed error messages for each possible failure. Let's teach the helper to optionally report these specific errors. This lets us convert another callsite, and means we can use the helper in other locations that want to give the same error messages. The logic and error messages come straight from sha1_name.c, with the exception that we start each error with a lowercase letter, as is our usual style (note that a few tests need updated as a result).

2015-01-06log.c: fix translation markingsLibravatar Kyle J. McKay1-2/+2
The parse_options API expects an array of alternative usage lines to which it automatically ads the language-appropriate "or" when displaying. Each of these options is marked for translation with N_ and then later translated when gettext is called on each element of the array. Since the N_ macro just expands to its argument, if two N_-marked strings appear next to each other without being separated by anything else such as a comma, the preprocessor will join them into one string. In that case two separate strings get marked for translation, but at runtime they have been joined into a single string passed to gettext which then fails to get translated because the combined string was never marked for translation. Fix this by properly separating the two N_ marked strings with a comma and removing the embedded "\n" and " or:" that are properly supplied by the parse_options API. Signed-off-by: Kyle J.

resolve_ref_unsafe takes a boolean argument for reading (a nonexistent ref resolves successfully for writing but not for reading). Change this to be a flags field instead, and pass the new constant RESOLVE_REF_READING when we want this behaviour. 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.

2014-10-14pass config slots as pointers instead of offsetsLibravatar Jonathan Nieder1-1/+1
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.

2014-06-13commit: record buffer length in cacheLibravatar Jeff King1-1/+1
Most callsites which use the commit buffer try to use the cached version attached to the commit, rather than re-reading from disk. Unfortunately, that interface provides only a pointer to the NUL-terminated buffer, with no indication of the original length. For the most part, this doesn't matter. People do not put NULs in their commit messages, and the log code is happy to treat it all as a NUL-terminated string. However, some code paths do care. For example, when checking signatures, we want to be very careful that we verify all the bytes to avoid malicious trickery. This patch just adds an optional "size" out-pointer to get_commit_buffer and friends. The existing callers all pass NULL (there did not seem to be any obvious sites where we could avoid an immediate strlen() call, though perhaps with some further refactoring we could).

2014-06-13provide a helper to free commit bufferLibravatar Jeff King1-4/+2
This converts two lines into one at each caller. But more importantly, it abstracts the concept of freeing the buffer, which will make it easier to change later. Note that we also need to provide a "detach" mechanism for a tricky case in index-pack. We are passed a buffer for the object generated by processing the incoming pack. If we are not using --strict, we just calculate the sha1 on that buffer and return, leaving the caller to free it. But if we are using --strict, we actually attach that buffer to an object, pass the object to the fsck functions, and then detach the buffer from the object again (so that the caller can free it as usual). In this case, we don't want to free the buffer ourselves, but just make sure it is no longer associated with the commit. Note that we are making the assumption here that the attach/detach process does not impact the buffer at all (e.g., it is never reallocated or modified). That holds true now, and we have no plans to change that. However, as we abstract the commit_buffer code, this dependency becomes less obvious. So when we detach, let's also make sure that we get back the same buffer that we gave to the commit_buffer code.

For example, "git format-patch --follow" will segfault during try_to_follow_renames, as we have no pathspecs at all. We can push this check down into diff_setup_done, which is probably a better place anyway. It is the diff code that introduces this restriction, so other parts of the code should not need to care themselves. Reported-by: "Michael S.
