reftable: file format documentation

Shawn Pearce explains:

Some repositories contain a lot of references (e.g. android at 866k,
rails at 31k). The reftable format provides:

- Near constant time lookup for any single reference, even when the
  repository is cold and not in process or kernel cache.
- Near constant time verification if a SHA-1 is referred to by at least
  one reference (for allow-tip-sha1-in-want).
- Efficient lookup of an entire namespace, such as `refs/tags/`.
- Support atomic push `O(size_of_update)` operations.
- Combine reflog storage with ref storage.

This file format spec was originally written in July, 2017 by Shawn
Pearce.  Some refinements since then were made by Shawn and by Han-Wen
Nienhuys based on experiences implementing and experimenting with the
format.  (All of this was in the context of our work at Google and
Google is happy to contribute the result to the Git project.)

4 years agodir: fix treatment of negated pathspecs
Elijah Newren [Fri, 5 Jun 2020 18:23:48 +0000 (18:23 +0000)] 
dir: fix treatment of negated pathspecs

do_match_pathspec() started life as match_pathspec_depth_1() and for
correctness was only supposed to be called from match_pathspec_depth().
match_pathspec_depth() was later renamed to match_pathspec(), so the
invariant we expect today is that do_match_pathspec() has no direct
callers outside of match_pathspec().

Unfortunately, this intention was lost with the renames of the two
functions, and additional calls to do_match_pathspec() were added in
commits 75a6315f74 ("ls-files: add pathspec matching for submodules",
2016-10-07) and 89a1f4aaf7 ("dir: if our pathspec might match files
under a dir, recurse into it", 2019-09-17).  Of course,
do_match_pathspec() had an important advantge over match_pathspec() --
match_pathspec() would hardcode flags to one of two values, and these
new callers needed to pass some other value for flags.  Also, although
calling do_match_pathspec() directly was incorrect, there likely wasn't
any difference in the observable end output, because the bug just meant
that fill_diretory() would recurse into unneeded directories.  Since
subsequent does-this-path-match checks on individual paths under the
directory would cause those extra paths to be filtered out, the only
difference from using the wrong function was unnecessary computation.

The second of those bad calls to do_match_pathspec() was involved -- via
either direct movement or via copying+editing -- into a number of later
refactors.  See commits 777b420347 ("dir: synchronize
treat_leading_path() and read_directory_recursive()", 2019-12-19),
8d92fb2927 ("dir: replace exponential algorithm with a linear one",
2020-04-01), and 95c11ecc73 ("Fix error-prone fill_directory() API; make
it only return matches", 2020-04-01).  The last of those introduced the
usage of do_match_pathspec() on an individual file, and thus resulted in
individual paths being returned that shouldn't be.

The problem with calling do_match_pathspec() instead of match_pathspec()
is that any negated patterns such as ':!unwanted_path` will be ignored.
Add a new match_pathspec_with_flags() function to fulfill the needs of
specifying special flags while still correctly checking negated
patterns, add a big comment above do_match_pathspec() to prevent others
from misusing it, and correct current callers of do_match_pathspec() to
instead use either match_pathspec() or match_pathspec_with_flags().

One final note is that DO_MATCH_LEADING_PATHSPEC needs special
consideration when working with DO_MATCH_EXCLUDE.  The point of
DO_MATCH_LEADING_PATHSPEC is that if we have a pathspec like
   */Makefile
and we are checking a directory path like
   src/module/component
that we want to consider it a match so that we recurse into the
directory because it _might_ have a file named Makefile somewhere below.
However, when we are using an exclusion pattern, i.e. we have a pathspec
like
   :(exclude)*/Makefile
we do NOT want to say that a directory path like
   src/module/component
is a (negative) match.  While there *might* be a file named 'Makefile'
somewhere below that directory, there could also be other files and we
cannot pre-emptively rule all the files under that directory out; we
need to recurse and then check individual files.  Adjust the
DO_MATCH_LEADING_PATHSPEC logic to only get activated for positive
pathspecs.

4 years agosparse-checkout: avoid staging deletions of all files
Elijah Newren [Fri, 5 Jun 2020 02:41:39 +0000 (02:41 +0000)] 
sparse-checkout: avoid staging deletions of all files

sparse-checkout's purpose is to update the working tree to have it
reflect a subset of the tracked files.  As such, it shouldn't be
switching branches, making commits, downloading or uploading data, or
staging or unstaging changes.  Other than updating the worktree, the
only thing sparse-checkout should touch is the SKIP_WORKTREE bit of the
index.  In particular, this sets up a nice invariant: running
sparse-checkout will never change the status of any file in `git status`
(reflecting the fact that we only set the SKIP_WORKTREE bit if the file
is safe to delete, i.e. if the file is unmodified).

Traditionally, we did a _really_ bad job with this goal.  The
predecessor to sparse-checkout involved manual editing of
.git/info/sparse-checkout and running `git read-tree -mu HEAD`.  That
command would stage and unstage changes and overwrite dirty changes in
the working tree.

The initial implementation of the sparse-checkout command was no better;
it simply invoked `git read-tree -mu HEAD` as a subprocess and had the
same caveats, though this issue came up repeatedly in review comments
and workarounds for the problems were put in place before the feature
was merged[1, 2, 3, 4, 5, 6; especially see 4 & 6].

[6] https://lore.kernel.org/git/20191121163706.GV23183@szeder.dev/

However, these workarounds, in addition to disabling the feature in a
number of important cases, also missed one special case.  I'll get back
to it later.

In the 2.27.0 cycle, the disabling of the feature was lifted by finally
replacing the internal equivalent of `git read-tree -mu HEAD` with
something that did what we wanted: the new update_sparsity() function in
unpack-trees.c that only ever updates SKIP_WORKTREE bits in the index
and updates the working tree to match.  This new function handles all
the cases that were problematic for the old implementation, except that
it breaks the same special case that avoided the workarounds of the old
implementation, but broke it in a different way.

So...that brings us to the special case: a git clone performed with
--no-checkout.  As per the meaning of the flag, --no-checkout does not
check out any branch, with the implication that you aren't on one and
need to switch to one after the clone.  Implementationally, HEAD is
still set (so in some sense you are partially on a branch), but
  * the index is "unborn" (non-existent)
  * there are no files in the working tree (other than .git/)
  * the next time git switch (or git checkout) is run it will run
    unpack_trees with `initial_checkout` flag set to true.
It is not until you run, e.g. `git switch <somebranch>` that the index
will be written and files in the working tree populated.

With this special --no-checkout case, the traditional `read-tree -mu
HEAD` behavior would have done the equivalent of acting like checkout --
switch to the default branch (HEAD), write out an index that matches
HEAD, and update the working tree to match.  This special case slipped
through the avoid-making-changes checks in the original sparse-checkout
command and thus continued there.

After update_sparsity() was introduced and used (see commit f56f31af03
("sparse-checkout: use new update_sparsity() function", 2020-03-27)),
the behavior for the --no-checkout case changed:  Due to git's
auto-vivification of an empty in-memory index (see do_read_index() and
note that `must_exist` is false), and due to sparse-checkout's
update_working_directory() code to always write out the index after it
was done, we got a new bug.  That made it so that sparse-checkout would
switch the repository from a clone with an "unborn" index (i.e. still
needing an initial_checkout), to one that had a recorded index with no
entries.  Thus, instead of all the files appearing deleted in `git
status` being known to git as a special artifact of not yet being on a
branch, our recording of an empty index made it suddenly look to git as
though it was definitely on a branch with ALL files staged for deletion!
A subsequent checkout or switch then had to contend with the fact that
it wasn't on an initial_checkout but had a bunch of staged deletions.

Make sure that sparse-checkout changes nothing in the index other than
the SKIP_WORKTREE bit; in particular, when the index is unborn we do not
have any branch checked out so there is no sparsification or
de-sparsification work to do.  Simply return from
update_working_directory() early.

4 years agodiff: discard blob data from stat-unmatched pairs
Jeff King [Mon, 1 Jun 2020 20:22:18 +0000 (16:22 -0400)] 
diff: discard blob data from stat-unmatched pairs

When performing a tree-level diff against the working tree, we may find
that our index stat information is dirty, so we queue a filepair to be
examined later. If the actual content hasn't changed, we call this a
stat-unmatch; the stat information was out of date, but there's no
actual diff.  Normally diffcore_std() would detect and remove these
identical filepairs via diffcore_skip_stat_unmatch().  However, when
"--quiet" is used, we want to stop the diff as soon as we see any
changes, so we check for stat-unmatches immediately in diff_change().

That check may require us to actually load the file contents into the
pair of diff_filespecs. If we find that the pair isn't a stat-unmatch,
then no big deal; we'd likely load the contents later anyway to generate
a patch, do rename detection, etc, so we want to hold on to it. But if
it is a stat-unmatch, then we have no more use for that data; the whole
point is that we're going discard the pair. However, we never free the
allocated diff_filespec data.

In most cases, keeping that data isn't a problem. We don't expect a lot
of stat-unmatch entries, and since we're using --quiet, we'd quit as
soon as we saw such a real change anyway. However, there are extreme
cases where it makes a big difference:

  1. We'd generally mmap() the working tree half of the pair. And since
     the OS may limit the total number of maps, we can run afoul of this
     in large repositories. E.g.:

       $ cd linux
       $ git ls-files | wc -l
       67959
       $ sysctl vm.max_map_count
       vm.max_map_count = 65530
       $ git ls-files | xargs touch ;# everything is stat-dirty!
       $ git diff --quiet
       fatal: mmap failed: Cannot allocate memory

     It should be unusual to have so many files stat-dirty, but it's
     possible if you've just run a script like "sed -i" or similar.

     After this patch, the above correctly exits with code 0.

  2. Even if you don't hit mmap limits, the index half of the pair will
     have been pulled from the object database into heap memory. Again
     in a clone of linux.git, running:

       $ git ls-files | head -n 10000 | xargs touch
       $ git diff --quiet

     peaks at 145MB heap before this patch, and 94MB after.

This patch solves the problem by freeing any diff_filespec data we
picked up during the "--quiet" stat-unmatch check in diff_changes.
Nobody is going to need that data later, so there's no point holding on
to it. There are a few things to note:

  - we could skip queueing the pair entirely, which could in theory save
    a little work. But there's not much to save, as we need a
    diff_filepair to feed to diff_filespec_check_stat_unmatch() anyway.
    And since we cache the result of the stat-unmatch checks, a later
    call to diffcore_skip_stat_unmatch() call will quickly skip over
    them. The diffcore code also counts up the number of stat-unmatched
    pairs as it removes them. It's doubtful any callers would care about
    that in combination with --quiet, but we'd have to reimplement the
    logic here to be on the safe side. So it's not really worth the
    trouble.

  - I didn't write a test, because we always produce the correct output
    unless we run up against system mmap limits, which are both
    unportable and expensive to test against. Measuring peak heap
    would be interesting, but our perf suite isn't yet capable of that.

  - note that diff without "--quiet" does not suffer from the same
    problem. In diffcore_skip_stat_unmatch(), we detect the stat-unmatch
    entries and drop them immediately, so we're not carrying their data
    around.

  - you _can_ still trigger the mmap limit problem if you truly have
    that many files with actual changes. But it's rather unlikely. The
    stat-unmatch check avoids loading the file contents if the sizes
    don't match, so you'd need a pretty trivial change in every single
    file. Likewise, inexact rename detection might load the data for
    many files all at once. But you'd need not just 64k changes, but
    that many deletions and additions. The most likely candidate is
    perhaps break-detection, which would load the data for all pairs and
    keep it around for the content-level diff. But again, you'd need 64k
    actually changed files in the first place.

    So it's still possible to trigger this case, but it seems like "I
    accidentally made all my files stat-dirty" is the most likely case
    in the real world.

fast-import: add new --date-format=raw-permissive format

There are multiple repositories in the wild with random, invalid
timezones.  Most notably is a commit from rails.git with a timezone of
"+051800"[1].  A few searches will find other repos with that same
invalid timezone as well.  Further, Peff reports that GitHub relaxed
their fsck checks in August 2011 to accept any timezone value[2], and
there have been multiple reports to filter-repo about fast-import
crashing while trying to import their existing repositories since they
had timezone values such as "-7349423" and "-43455309"[3].

The existing check on timezone values inside fast-import may prove
useful for people who are crafting fast-import input by hand or with a
new script.  For them, the check may help them avoid accidentally
recording invalid dates.  (Note that this check is rather simplistic and
there are still several forms of invalid dates that fast-import does not
check for: dates in the future, timezone values with minutes that are
not divisible by 15, and timezone values with minutes that are 60 or
greater.)  While this simple check may have some value for those users,
other users or tools will want to import existing repositories as-is.
Provide a --date-format=raw-permissive format that will not error out on
these otherwise invalid timezones so that such existing repositories can
be imported.

checkout -p: handle new files correctly

The original patch selection code was written for `git add -p`, and the
fundamental unit on which it works is a hunk.

We hacked around that to handle deletions back in 24ab81ae4d
(add-interactive: handle deletion of empty files, 2009-10-27). But `git
add -p` would never see a new file, since we only consider the set of
tracked files in the index.

However, since the same machinery was used for `git checkout -p` &
friends, we can see new files.

Handle this case specifically, adding a new prompt for it that is
modeled after the `deleted file` case.

This also fixes the problem where added _empty_ files could not be
staged via `git checkout -p`.

4 years agorev-list-options.txt: start a list for `show-pulls`

rev-list-options.txt: start a list for `show-pulls`

The explanation of the `--show-pulls` option added in commit 8d049e182e
("revision: --show-pulls adds helpful merges", 2020-04-10) consists of
several paragraphs and we use "+" throughout to tie them together in one
long chain of list continuations. Only thing is, we're not in any kind
of list, so these pluses end up being rendered literally.

The preceding few paragraphs describe `--ancestry-path` and there we
*do* have a list, since we've started one with `--ancestry-path::`. In
fact, we have several such lists for all the various history-simplifying
options we're discussing earlier in this file.

Thus, we're missing a list both from a consistency point of view and
from a practical rendering standpoint.

Let's start a list for `--show-pulls` where we start actually discussing
the option, and keep the paragraphs preceding it out of that list. That
is, drop all those pluses before the new list we're adding here.
