|\ | | | | | | | | | | | | | | | | | | | | | | "git blame file" allowed the lineage of lines in the uncommitted, unadded contents of "file" to be inspected, but it refused when "file" did not appear in the current commit. When "file" was created by renaming an existing file (but the change has not been committed), this restriction was unnecessarily tight. * mh/blame-worktree: t/t8003-blame-corner-cases.sh: Use here documents blame: allow to blame paths freshly added to the index
| * blame: allow to blame paths freshly added to the indexMike Hommey2016-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When blaming files, changes in the work tree are taken into account and displayed as being "Not Committed Yet". However, when blaming a file that is not known to the current HEAD, git blame fails with `no such path 'foo' in HEAD`, even when the file was git add'ed. Allowing such a blame is useful when the new file added to the index (not yet committed) was created by renaming an existing file. It also is useful when the new file was created from pieces already in HEAD, moved or copied from other files and blaming with copy detection (i.e. "-C").

You can tell the difference by the strdup_strings flag, and one should use either STRING_LIST_INIT_DUP, or STRING_LIST_INIT_NODUP as an initializer. Historically, the normal all-zeros initialization has corresponded to the NODUP case. Many sites use no initializer at all, and that works as a shorthand for that case. But for a reader of the code, it can be hard to remember which is which. Let's be more explicit and actually have each site declare which type it means to use. This is a fairly mechanical conversion; I assumed each site was correct as-is, and just switched them all to NODUP.

Note that in some cases we may need to actually initialize the variables (since we cannot rely on BSS to do so). This is a net improvement to readability, though, as we can use the more verbose initializers for our string_lists.

Originally, the loop had two outputs: a commit to stuff into sb->final, and the name of the commit from the rev->pending array. After the refactor, that loop is put in its own function with a single return value: the object_array_entry from the rev->pending array. This contains both the name and the object, but with one important difference: the object is the _original_ object found by the revision parser, not the dereferenced commit. If one feeds a tag to "git blame", we end up casting the tag object to a "struct commit", which causes a segfault. Instead, let's return the commit (properly casted) directly from the function, and take the "name" as an optional out-parameter. This does the right thing, and actually simplifies the callers, who no longer need to cast or dereference the object_array_entry themselves.

Normally we could improve a dynamic allocation like this by using xstrfmt, but it doesn't work here; we have to account for the size of the rest of the struct. But we can improve things a bit by storing the length that we use for the allocation, and then feeding it to xsnprintf or memcpy, which makes it more obvious that we are not writing more than the allocated number of bytes. It would be nice if we had some kind of helper for allocating generic flex arrays, but it doesn't work that well: - the call signature is a little bit unwieldy: d = flex_struct(sizeof(*d), offsetof(d, path), fmt, ...); You need offsetof here instead of just writing to the end of the base size, because we don't know how the struct is packed (partially this is because FLEX_ARRAY might not be zero, though we can account for that; but the size of the struct may actually be rounded up for alignment, and we can't know that). - some sites do clever things, like over-allocating because they know they will write larger things into the buffer later (e.g., struct packed_git here). So we're better off to just write out each allocation (or add type-specific helpers, though many of these are one-off allocations anyway).

Let's convert them to sha1_to_hex_r(), and likewise for some calls to find_unique_abbrev(). While we're here, we'll double-check that all of the buffers are correctly sized, and use the more obvious GIT_SHA1_HEXSZ constant.

Typically by ignoring the return of our xdi_diff wrapper, but sometimes we even propagate that return value up and then ignore it later. This can lead to us silently producing incorrect diffs (e.g., "git log" might produce no output at all, not even a diff header, for a content-level diff). In practice this does not happen very often, because the typical reason for xdiff to report failure is that it malloc() failed (it uses straight malloc, and not our xmalloc wrapper). But it could also happen when xdiff triggers one our callbacks, which returns an error (e.g., outf() in builtin/rerere.c tries to report a write failure in this way). And the next patch also plans to add more failure modes. Let's notice an error return from xdiff and react appropriately. In most of the diff.c code, we can simply die(), which matches the surrounding code (e.g., that is what we do if we fail to load a file for diffing in the first place). This is not that elegant, but we are probably better off dying to let the user know there was a problem, rather than simply generating bogus output. We could also just die() directly in xdi_diff, but the callers typically have a bit more context, and can provide a better message (and if we do later decide to pass errors up, we're one step closer to doing so). There is one interesting case, which is in diff_grep(). Here if we cannot generate the diff, there is nothing to match, and we silently return "no hits". This is actually what the existing code does already, but we make it a little more explicit. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
