2 weeks agostash: handle staged changes in skip-worktree files correctly
Johannes Schindelin [Wed, 30 Oct 2019 10:49:38 +0000 (10:49 +0000)] 
stash: handle staged changes in skip-worktree files correctly

When calling `git stash` while changes were staged for files that are
marked with the `skip-worktree` bit (e.g. files that are excluded in a
sparse checkout), the files are recorded as _deleted_ instead.

The reason is that `git stash` tries to construct the tree reflecting
the worktree essentially by copying the index to a temporary one and
then updating the files from the worktree. Crucially, it calls `git
diff-index` to update also those files that are in the HEAD but have
been unstaged in the index.

However, when the temporary index is updated via `git update-index --add
--remove`, skip-worktree entries mark the files as deleted by mistake.

Let's use the newly-introduced `--ignore-skip-worktree-entries` option
of `git update-index` to prevent exactly this from happening.

Note that the regression test case deliberately avoids replicating the
scenario described above and instead tries to recreate just the symptom.

update-index: optionally leave skip-worktree entries alone

While `git update-index` mostly ignores paths referring to index entries
whose skip-worktree bit is set, in b4d1690df11 (Teach Git to respect
skip-worktree bit (reading part), 2009-08-20), for reasons that are not
entirely obvious, the `--remove` option was made special: it _does_
remove index entries even if their skip-worktree bit is set.

Seeing as this behavior has been in place for a decade now, it does not
make sense to change it.

However, in preparation for fixing a bug in `git stash` where it
pretends that skip-worktree entries have actually been removed, we need
a mode where `git update-index` leaves all skip-worktree entries alone,

2 weeks agomanpage-bold-literal.xsl: match for namespaced "d:literal" in template
Martin Ågren [Thu, 31 Oct 2019 06:22:27 +0000 (07:22 +0100)] 
manpage-bold-literal.xsl: match for namespaced "d:literal" in template

We recently regressed our rendering with Asciidoctor of "literal"
elements in our manpages, i.e, stuff we have placed within `backticks`
in order to render as monospace. In particular, we lost the bold
rendering of such literal text.

The culprit is f6461b82b9 ("Documentation: fix build with Asciidoctor 2",
2019-09-15), where we switched from DocBook 4.5 to DocBook 5 with
Asciidoctor. As part of the switch, we started using the namespaced
DocBook XSLT stylesheets rather than the non-namespaced ones. (See
f6461b82b9 for more details on why we changed to the namespaced ones.)

The bold literals are implemented as an XSLT snippet <xsl:template
match="literal">...</xsl:template>. Now that we use namespaces, this
doesn't pick up our literals like it used to.

Match for "d:literal" in addition to just "literal", after defining the
d namespace. ("d" is what
http://docbook.sourceforge.net/release/xsl-ns/current/manpages/docbook.xsl
uses.) Note that we need to keep matching without the namespace for
AsciiDoc.

This boldness was introduced by 5121a6d993 ("Documentation: option to
render literal text as bold for manpages", 2009-03-27) and made the
default in 5945717009 ("Documentation: bold literals in man",
2016-05-31).

One reason this was not caught in review is that our doc-diff tool diffs
without any boldness, i.e., it "only" compares text. As pointed out by
Peff in review of this patch, one can use `MAN_KEEP_FORMATTING=1
./doc-diff <...>`

This has been optically tested with AsciiDoc 8.6.10, Asciidoctor 1.5.5
and Asciidoctor 2.0.10. I've also verified that doc-diff produces the
empty output for all three programs, as expected, and that with the
MAN_KEEP_FORMATTING trick, AsciiDoc yields no diff, whereas with
Asciidoctor, we get bold literals, just like we want.

commit-graph: fix writing first commit-graph during fetch

The previous commit includes a failing test for an issue around
fetch.writeCommitGraph and fetching in a repo with a submodule. Here, we
fix that bug and set the test to "test_expect_success".

The problem arises with this set of commands when the remote repo at
<url> has a submodule. Note that --recurse-submodules is not needed to
demonstrate the bug.

$ git clone <url> test
$ cd test
$ git -c fetch.writeCommitGraph=true fetch origin
Computing commit graph generation numbers: 100% (12/12), done.
BUG: commit-graph.c:886: missing parent <hash1> for commit <hash2>
Aborted (core dumped)

As an initial fix, I converted the code in builtin/fetch.c that calls
write_commit_graph_reachable() to instead launch a "git commit-graph
write --reachable --split" process. That code worked, but is not how we
want the feature to work long-term.

That test did demonstrate that the issue must be something to do with
internal state of the 'git fetch' process.

The write_commit_graph() method in commit-graph.c ensures the commits we
plan to write are "closed under reachability" using close_reachable().
This method walks from the input commits, and uses the UNINTERESTING
flag to mark which commits have already been visited. This allows the
walk to take O(N) time, where N is the number of commits, instead of
O(P) time, where P is the number of paths. (The number of paths can be
exponential in the number of commits.)

However, the UNINTERESTING flag is used in lots of places in the
codebase. This flag usually means some barrier to stop a commit walk,
such as in revision-walking to compare histories. It is not often
cleared after the walk completes because the starting points of those
walks do not have the UNINTERESTING flag, and clear_commit_marks() would
stop immediately.

This is happening during a 'git fetch' call with a remote. The fetch
negotiation is comparing the remote refs with the local refs and marking
some commits as UNINTERESTING.

I tested running clear_commit_marks_many() to clear the UNINTERESTING
flag inside close_reachable(), but the tips did not have the flag, so
that did nothing.

It turns out that the calculate_changed_submodule_paths() method is at
fault. Thanks, Peff, for pointing out this detail! More specifically,
for each submodule, the collect_changed_submodules() runs a revision
walk to essentially do file-history on the list of submodules. That
revision walk marks commits UNININTERESTING if they are simplified away
by not changing the submodule.

Instead, I finally arrived on the conclusion that I should use a flag
that is not used in any other part of the code. In commit-reach.c, a
number of flags were defined for commit walk algorithms. The REACHABLE
flag seemed like it made the most sense, and it seems it was not
actually used in the file. The REACHABLE flag was used in early versions
of commit-reach.c, but was removed by 4fbcca4 (commit-reach: make
can_all_from_reach... linear, 2018-07-20).

Add the REACHABLE flag to commit-graph.c and use it instead of
UNINTERESTING in close_reachable(). This fixes the bug in manual
testing.

documentation: remove empty doc files

Remove empty and redundant documentation files from the
Documentation/technical/ directory.

The empty doc files included only TODO messages with no documentation for
years. Instead an approach is being taken to keep all doc beside the code
in the relevant header files.
Having empty doc files is confusing and disappointing to anybody looking
for information, besides having the documentation in header files makes it
easier for developers to find the information they are looking for.

Some of the content which could have gone here already exists elsewhere:
- api-object-access.txt -> sha1-file.c and object.h have some details.
- api-quote.txt -> quote.h has some details.
- api-xdiff-interface.txt -> xdiff-interface.h has some details.

'logs/refs' is not a working tree-specific path, but since commit
b9317d55a3 (Make sure refs/rewritten/ is per-worktree, 2019-03-07)
'git rev-parse --git-path' has been returning a bogus path if a
trailing '/' is present:

  /home/szeder/src/git/.git/logs/refs
  /home/szeder/src/git/.git/worktrees/WT/logs/refs/

We use a trie data structure to efficiently decide whether a path
belongs to the common dir or is working tree-specific.  As it happens
b9317d55a3 triggered a bug that is as old as the trie implementation
itself, added in 4e09cf2acf (path: optimize common dir checking,
2015-08-31).

  - According to the comment describing trie_find(), it should only
    call the given match function 'fn' for a "/-or-\0-terminated
    prefix of the key for which the trie contains a value".  This is
    not true: there are three places where trie_find() calls the match
    function, but one of them is missing the check for value's
    existence.

  - b9317d55a3 added two new keys to the trie: 'logs/refs/rewritten'
    and 'logs/refs/worktree', next to the already existing
    'logs/refs/bisect'.  This resulted in a trie node with the path
    'logs/refs/', which didn't exist before, and which doesn't have a
    value attached.  A query for 'logs/refs/' finds this node and then
    hits that one callsite of the match function which doesn't check
    for the value's existence, and thus invokes the match function
    with NULL as value.

  - When the match function check_common() is invoked with a NULL
    value, it returns 0, which indicates that the queried path doesn't
    belong to the common directory, ultimately resulting the bogus
    path shown above.

Add the missing condition to trie_find() so it will never invoke the
match function with a non-existing value.  check_common() will then no
longer have to check that it got a non-NULL value, so remove that
condition.

I believe that there are no other paths that could cause similar bogus
output.  AFAICT the only other key resulting in the match function
being called with a NULL value is 'co' (because of the keys 'common'
and 'config').  However, as they are not in a directory that belongs
to the common directory the resulting working tree-specific path is
expected.

cases.

Finally, basically everything refers to the data stored for a key as
"value", with two confusing exceptions:

  - The type definition of the match function calls its corresponding
    parameter 'data'.
    Rename that parameter to 'value'.  (check_common(), the only
    function of this type already calls it 'value').

  - The table of examples above trie_find() has a "val from node"
    column, which has nothing to do with the value stored in the trie:

    that led to that node.
    Rename that column header to "prefix to node".

Note that neither the original nor the updated description and

3 weeks agomulti-pack-index: add [--[no-]progress] option.
William Baker [Mon, 21 Oct 2019 18:40:03 +0000 (18:40 +0000)] 
multi-pack-index: add [--[no-]progress] option.

Add the --[no-]progress option to git multi-pack-index.
Pass the MIDX_PROGRESS flag to the subcommand functions
when progress should be displayed by multi-pack-index.
The progress feature was added to 'verify' in 144d703
("multi-pack-index: report progress during 'verify'", 2018-09-13)
but some subcommands were not updated to display progress, and
the ability to opt-out was overlooked.
