2018-06-25Merge branch 'nd/commit-util-to-slab'Libravatar Junio C Hamano1-4/+13
The in-core "commit" object had an all-purpose "void *util" field, which was tricky to use especially in library-ish part of the code. All of the existing uses of the field has been migrated to a more dedicated "commit-slab" mechanism and the field is eliminated. * nd/commit-util-to-slab: commit.h: delete 'util' field in struct commit merge: use commit-slab in merge remote desc instead of commit->util log: use commit-slab in prepare_bases() instead of commit->util show-branch: note about its object flags usage show-branch: use commit-slab for commit-name instead of commit->util name-rev: use commit-slab for rev-name instead of commit->util bisect.c: use commit-slab for commit weight instead of commit->util revision.c: use commit-slab for show_source sequencer.c: use commit-slab to associate todo items to commits sequencer.c: use commit-slab to mark seen commits shallow.c: use commit-slab for commit depth instead of commit->util describe: use commit-slab for commit names instead of commit->util blame: use commit-slab for blame suspects instead of commit->util commit-slab: support shared commit-slab commit-slab.h: code split

2018-05-02format-patch: make cover letters always text/plainLibravatar brian m. carlson1-1/+1
When formatting a series of patches using --attach and --cover-letter, the cover letter lacks the closing MIME boundary, violating RFC 2046. Certain clients, such as Thunderbird, discard the message body in such a case. Since the cover letter is just one part and sending it as multipart/mixed is not very useful, always emit it as text/plain, avoiding the boundary problem altogether.

In anticipation of making trees load lazily, create a Coccinelle script (contrib/coccinelle/commit.cocci) to ensure that all references to the 'maybe_tree' member of struct commit are either mutations or accesses through get_commit_tree() or get_commit_tree_oid().

2018-04-11treewide: rename tree to maybe_treeLibravatar Derrick Stolee1-2/+2
Using the commit-graph file to walk commit history removes the large cost of parsing commits during the walk. This exposes a performance issue: lookup_tree() takes a large portion of the computation time, even when Git never uses those trees. In anticipation of lazy-loading these trees, rename the 'tree' member of struct commit to 'maybe_tree'. This serves two purposes: it hints at the future role of possibly being NULL even if the commit has a valid tree, and it allows for unambiguous transformation from simple member access (i.e. commit->maybe_tree) to method access.

2018-02-02format-patch: reduce patch diffstat width to 72Libravatar Nguyễn Thái Ngọc Duy1-0/+2
Patches generated by format-patch are meant to be exchanged as emails, most of the time. And since it's generally agreed that text in mails should be wrapped around 70 columns or so, make sure these diffstat follow the convention (especially when used with --cover-letter since we already defaults to wrapping 72 columns).

2018-01-04diff: introduce DIFF_PICKAXE_KINDS_MASKLibravatar Stefan Beller1-2/+2
Currently the check whether to perform pickaxing is done via checking `diffopt->pickaxe`, which contains the command line argument that we want to pickaxe for. Soon we'll introduce a new type of pickaxing, that will not store anything in the `.pickaxe` field, so let's migrate the check to be dependent on pickaxe_opts. It is not enough to just replace the check for pickaxe by pickaxe_opts, because flags might be set, but pickaxing was not requested ('-i'). To cope with that, introduce a mask to check only for the bits indicating the modes of operation. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-11-22log: add option to choose which refs to decorateLibravatar Rafael Ascensão1-1/+9
When `log --decorate` is used, git will decorate commits with all available refs. While in most cases this may give the desired effect, under some conditions it can lead to excessively verbose output. Introduce two command line options, `--decorate-refs=<pattern>` and `--decorate-refs-exclude=<pattern>` to allow the user to select which refs are used in decoration. When "--decorate-refs=<pattern>" is given, only the refs that match the pattern are used in decoration. The refs that match the pattern when "--decorate-refs-exclude=<pattern>" is given, are never used in decoration. These options follow the same convention for mixing negative and positive patterns across the system, assuming that the inclusive default is to match all refs available. (1) if there is no positive pattern given, pretend as if an inclusive default positive pattern was given; (2) for each candidate, reject it if it matches no positive pattern, or if it matches any one of the negative patterns. The rules for what is considered a match are slightly different from the rules used elsewhere. Commands like `log --glob` assume a trailing '/*' when glob chars are not present in the pattern. This makes it difficult to specify a single ref. On the other hand, commands like `describe --match --all` allow specifying exact refs, but do not have the convenience of allowing "shorthand refs" like 'refs/heads' or 'heads' to refer to 'refs/heads/*'. The commands introduced in this patch consider a match if: (a) the pattern contains globs chars, and regular pattern matching returns a match. (b) the pattern does not contain glob chars, and ref '<pattern>' exists, or if ref exists under '<pattern>/' This allows both behaviours (allowing single refs and shorthand refs) yet remaining compatible with existent commands.

2017-11-01diff: add flag to indicate textconv was set via cmdlineLibravatar Brandon Williams1-1/+1
git-show is unique in that it wants to use textconv by default except for when it is showing blobs. When asked to show a blob, show doesn't want to use textconv unless the user explicitly requested that it be used by providing the command line flag '--textconv'. Currently this is done by using a parallel set of 'touched' flags which get set every time a particular flag is set or cleared. In a future patch we want to eliminate this parallel set of flags so instead of relying on if the textconv flag has been touched, add a new flag 'TEXTCONV_SET_VIA_CMDLINE' which is only set if textconv is set to true via the command line.

When generating patches for the rebase command, if the user does not realize the branch they are rebasing onto is thousands of commits different, there is no progress indication after initial rewinding message. The progress meter as presented in this patch assumes the thousands of patches to have a fine granularity as well as assuming to require all the same amount of work/time for each, such that a steady progress bar is achieved. We do not want to estimate the time for each patch based e.g. on their size or number of touched files (or parents) as that is too expensive for just a progress meter. This patch allows a progress option to be passed to format-patch so that the user can be informed the progress of generating the patch.

For this reason, we hold on to the commit buffer for each commit rather than freeing it after we've showed the commit. We should do the same for the parent list.

2017-06-15config: don't include config.h by defaultLibravatar Brandon Williams1-0/+1
Stop including config.h by default in cache.h. Instead only include config.h in those files which require use of the config system. Signed-off-by: Brandon Williams <bmwill@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The result from "git diff" that compares two blobs, e.g. "git diff $commit1:$path $commit2:$path", used to be shown with the full object name as given on the command line, but it is more natural to use the $path in the output and use it to look up .gitattributes. * jk/diff-blob: diff: use blob path for blob/file diffs diff: use pending "path" if it is available diff: use the word "path" instead of "name" for blobs diff: pass whole pending entry in blobinfo handle_revision_arg: record paths for pending objects handle_revision_arg: record modes for "a..b" endpoints t4063: add tests of direct blob diffs get_sha1_with_context: dynamically allocate oc->path get_sha1_with_context: always initialize oc->symlink_path sha1_name: consistently refer to object_context as "oc" handle_revision_arg: add handle_dotdot() helper handle_revision_arg: hoist ".." check out of range parsing handle_revision_arg: stop using "dotdot" as a generic pointer handle_revision_arg: simplify commit reference lookups handle_revision_arg: reset "dotdot" consistently
