2014-05-08blame: correctly handle files regardless of autocrlfLibravatar brian m. carlson1-1/+0
If a file contained CRLF line endings in a repository with core.autocrlf=input, then blame always marked lines as "Not Committed Yet", even if they were unmodified. Don't attempt to convert the line endings when creating the fake commit so that blame works correctly regardless of the autocrlf setting.

2014-04-23blame: dynamic blame_date_width for different localesLibravatar Jiang Xin1-1/+8
When show date in relative date format for git-blame, the max display width of datetime is set as the length of the string "Thu Oct 19 16:00:04 2006 -0700" (30 characters long). But actually the max width for C locale is only 22 (the length of string "x years, xx months ago"). And for other locale, it maybe smaller. E.g. For Chinese locale, only needs a half (16-character width). Set blame_date_width as the display width of _("4 years, 11 months ago"), so that translators can make the choice.

2014-04-23blame: fix broken time_buf paddings in relative timestampLibravatar Jiang Xin1-7/+14
Command `git blame --date relative` aligns the date field with a fixed-width (defined by blame_date_width), and if time_str is shorter than that, it adds spaces for padding. But there are two bugs in the following codes: time_len = strlen(time_str); ... memset(time_buf + time_len, ' ', blame_date_width - time_len); 1. The type of blame_date_width is size_t, which is unsigned. If time_len is greater than blame_date_width, the result of "blame_date_width - time_len" will never be a negative number, but a really big positive number, and will cause memory overwrite. This bug can be triggered if either l10n message for function show_date_relative() in date.c is longer than 30 characters, then `git blame --date relative` may exit abnormally. 2. When show blame information with relative time, the UTF-8 characters in time_str will break the alignment of columns after the date field. This is because the time_buf padding with spaces should have a constant display width, not a fixed strlen size. So we should call utf8_strwidth() instead of strlen() for width calibration.

There is no reason to have a hardcoded upper limit of the number of parents for an octopus merge, created via the graft mechanism. * js/lift-parent-count-limit: Remove the line length limit for graft files
2013-12-27Remove the line length limit for graft filesLibravatar Johannes Schindelin1-4/+4
Support for grafts predates Git's strbuf, and hence it is understandable that there was a hard-coded line length limit of 1023 characters (which was chosen a bit awkwardly, given that it is *exactly* one byte short of aligning with the 41 bytes occupied by a commit name and the following space or new-line character). While regular commit histories hardly win comprehensibility in general if they merge more than twenty-two branches in one go, it is not Git's business to limit grafts in such a way. In this particular developer's case, the use case that requires substantially longer graft lines to be supported is the visualization of the commits' order implied by their changes: commits are considered to have an implicit relationship iff exchanging them in an interactive rebase would result in merge conflicts. Thusly implied branches tend to be very shallow in general, and the resulting thicket of implied branches is usually very wide; It is actually quite common that *most* of the commits in a topic branch have not even one implied parent, so that a final merge commit has about as many implied parents as there are commits in said branch.

2013-10-28pathspec: stop --*-pathspecs impact on internal parse_pathspec() usesLibravatar Nguyễn Thái Ngọc Duy1-1/+3
Normally parse_pathspec() is used on command line arguments where it can do fancy thing like parsing magic on each argument or adding magic for all pathspecs based on --*-pathspecs options. There's another use of parse_pathspec(), where pathspec is needed, but the input is known to be pure paths. In this case we usually don't want --*-pathspecs to interfere. And we definitely do not want to parse magic in these paths, regardless of --literal-pathspecs. Add new flag PATHSPEC_LITERAL_PATH for this purpose. When it's set, --*-pathspecs are ignored, no magic is parsed. And if the caller allows PATHSPEC_LITERAL (i.e. the next calls can take literal magic), then PATHSPEC_LITERAL will be set. This fixes cases where git chokes when GIT_*_PATHSPECS are set because parse_pathspec() indicates it won't take any magic. But GIT_*_PATHSPECS add them anyway. These are export GIT_LITERAL_PATHSPECS=1 git blame -- something git log --follow something git log --merge "git ls-files --with-tree=path" (aka parse_pathspec() in overlay_tree_on_cache()) is safe because the input is empty, and producing one pathspec due to PATHSPEC_PREFER_CWD does not take any magic into account.

2013-01-26logmsg_reencode: lazily load missing commit buffersLibravatar Jeff King1-13/+0
Usually a commit that makes it to logmsg_reencode will have been parsed, and the commit->buffer struct member will be valid. However, some code paths will free commit buffers after having used them (for example, the log traversal machinery will do so to keep memory usage down). Most of the time this is fine; log should only show a commit once, and then exits. However, there are some code paths where this does not work. At least two are known: 1. A commit may be shown as part of a regular ref, and then it may be shown again as part of a submodule diff (e.g., if a repo contains refs to both the superproject and subproject). 2. A notes-cache commit may be shown during "log --all", and then later used to access a textconv cache during a diff. Lazily loading in logmsg_reencode does not necessarily catch all such cases, but it should catch most of them. Users of the commit buffer tend to be either parsing for structure (in which they will call parse_commit, and either we will already have parsed, or we will load commit->buffer lazily there), or outputting (either to the user, or fetching a part of the commit message via format_commit_message). In the latter case, we should always be using logmsg_reencode anyway (and typically we do so via the pretty-print machinery). If there are any cases that this misses, we can fix them up to use logmsg_reencode (or handle them on a case-by-case basis if that is inappropriate).

2013-01-26logmsg_reencode: never return NULLLibravatar Jeff King1-5/+4
The logmsg_reencode function will return the reencoded commit buffer, or NULL if reencoding failed or no reencoding was necessary. Since every caller then ends up checking for NULL and just using the commit's original buffer, anyway, we can be a bit more helpful and just return that buffer when we would have returned NULL. Since the resulting string may or may not need to be freed, we introduce a logmsg_free, which checks whether the buffer came from the commit object or not (callers either implemented the same check already, or kept two separate pointers, one to mark the buffer to be used, and one for the to-be-freed string). Pushing this logic into logmsg_* simplifies the callers, and will let future patches lazily load the commit buffer in a single place.

The verify_working_tree_path() function introduced in the previous patch to notice a typo in the filename (primarily on case insensitive filesystems) has been updated to allow a filename that does not exist in HEAD (i.e. the tip of our history) as long as it exists one of the commits being merged, so that a "we deleted, the other side modified" case tracks the history of the file in the history of the other side.

2012-09-10blame $path: avoid getting fooled by case insensitive filesystemsLibravatar Junio C Hamano1-2/+14
"git blame MAKEFILE" run in a history that has "Makefile" but not MAKEFILE can get confused on a case insensitive filesystem, because the check we run to see if there is a corresponding file in the working tree with lstat("MAKEFILE") succeeds. In addition to that check, we have to make sure that the given path also exists in the commit we start digging history from (i.e. "HEAD"). Note that this reveals the breakage in a test added in cd8ae20 (git-blame shouldn't crash if run in an unmerged tree, 2007-10-18), which expects the entire merge-in-progress path to be blamed to the working tree when it did not exist in our tree. As it is clear in the log message of that commit, the old breakage was that it was causing an internal error and the fix was about avoiding it. Just check that the command does not die an uncontrolled death. For this particular case, the blame should fail, as the history for the file in that contents has not been committed yet at the point in the test. Signed-off-by: Junio C Hamano <gitster@pobox.com>
