the best name to explain commit C, and the tag is stored in a
"wrong" place in the refs/tags hierarchy, e.g. refs/tags/B, the
command gave a warning message but used A (not B) to describe C.

This test runs a function which itself runs several assertions.  The

since when run with EXPENSIVE set, the function is invoked a second time

However, as of 2ac0d6273f ("rebase: change the default backend from "am"
to "merge"", 2020-02-15), the default backend of rebase has changed, and
cleaning up the rebase-apply directory has no effect: it no longer
exists, since we're using rebase-merge instead.

Since we don't really care which rebase backend is in use, let's just
use the command "git rebase --quit", which will do the right thing
regardless.

git-gui: create a new namespace for chord script evaluation

Evaluating the script in the same namespace as the chord itself creates
potential for variable name collision. And in that case the script would
unknowingly use the chord's variables.

For example, say the script has a variable called 'is_completed', which
also exists in the chord's namespace. The script then calls 'eval' and
sets 'is_completed' to 1 thinking it is setting its own variable,
completely unaware of how the chord works behind the scenes. This leads
to the chord never actually executing because it sees 'is_completed' as
true and thinks it has already completed.

Avoid the potential collision by creating a separate namespace for the
script that is a child of the chord's namespace.

git-gui: reduce Tcl version requirement from 8.6 to 8.5

On some MacOS distributions like High Sierra, Tcl 8.5 is shipped by
default. This makes git-gui error out at startup because of the version
mismatch.

The only part that requires Tcl 8.6 is SimpleChord, which depends on
TclOO. So, don't use it and use our homegrown class.tcl instead.

This means some slight syntax changes. Since class.tcl doesn't have an
"unknown" method like TclOO does, we can't just call '$note', but have
to use '$note activate' instead. The constructor now needs a proper
namespace qualifier. Update the documentation to reflect the new syntax.

As of now, the only part of git-gui that needs Tcl 8.5 is a call to
'apply' in lib/index.tcl::lambda. Keep using it until someone shows up
shouting that their OS ships with 8.4 only. Then we would have to look
into implementing it in pure Tcl.

Now that we have the codebase wired up to pass any additional metadata
to filters, let's collect the additional metadata that we'd like to
pass.

The two main places we pass this metadata are checkouts and archives.
In these two situations, reading HEAD isn't a valid option, since HEAD
isn't updated for checkouts until after the working tree is written and
archives can accept an arbitrary tree.  In other situations, HEAD will
usually reflect the refname of the branch in current use.

We pass a smaller amount of data in other cases, such as git cat-file,
where we can really only logically know about the blob.

This commit updates only the parts of the checkout code where we don't
use unpack_trees.  That function and callers of it will be handled in a
future commit.

convert: permit passing additional metadata to filter processes

There are a variety of situations where a filter process can make use of
some additional metadata.  For example, some people find the ident
filter too limiting and would like to include the commit or the branch
in their smudged files.  This information isn't available during
checkout as HEAD hasn't been updated at that point, and it wouldn't be
available in archives either.

Let's add a way to pass this metadata down to the filter.  We pass the
blob we're operating on, the treeish (preferring the commit over the
tree if one exists), and the ref we're operating on.  Note that we won't
pass this information in all cases, such as when renormalizing or when
we're performing diffs, since it doesn't make sense in those cases.

The data we currently get from the filter process looks like the
following:

  command=smudge
  pathname=git.c
  0000

With this change, we'll get data more like this:

  command=smudge
  pathname=git.c
  refname=refs/tags/v2.25.1
  treeish=c522f061d551c9bb8684a7c3859b2ece4499b56b
  blob=7be7ad34bd053884ec48923706e70c81719a8660
  0000

There are a couple things to note about this approach.  For operations
like checkout, treeish will always be a commit, since we cannot check
out individual trees, but for other operations, like archive, we can end
up operating on only a particular tree, so we'll provide only a tree as
the treeish.  Similar comments apply for refname, since there are a
variety of cases in which we won't have a ref.

This commit wires up the code to print this information, but doesn't

Derrick Stolee [Fri, 13 Mar 2020 21:11:55 +0000 (21:11 +0000)] 
connected.c: reprepare packs for corner cases

While updating the microsoft/git fork on top of v2.26.0-rc0 and
consuming that build into Scalar, I noticed a corner case bug around
partial clone.

The "scalar clone" command can create a Git repository with the
proper config for using partial clone with the "blob:none" filter.
Instead of calling "git clone", it runs "git init" then sets a few
more config values before running "git fetch".

In our builds on v2.26.0-rc0, we noticed that our "git fetch"
command was failing with

  error: https://github.com/microsoft/scalar did not send all necessary objects

This does not happen if you copy the config file from a repository
created by "git clone --filter=blob:none <url>", but it does happen
when adding the config option "core.logAllRefUpdates = true".

By debugging, I was able to see that the loop inside
check_connnected() that checks if all refs are contained in
promisor packs actually did not have any packfiles in the packed_git
list.

I'm not sure what corner-case issues caused this config option to
prevent the reprepare_packed_git() from being called at the proper
spot during the fetch operation. This approach requires a situation
where we use the remote helper process, which makes it difficult to
test.

It is possible to place a reprepare_packed_git() call in the fetch code
closer to where we receive a pack, but that leaves an opening for a
later change to re-introduce this problem. Further, a concurrent repack
operation could replace the pack-file list we already loaded into
memory, causing this issue in an even harder to reproduce scenario.

It is really the responsibility of anyone looping through the list of
pack-files for a certain object to fall back to reprepare_packed_git()
on a fail-to-find. The loop in check_connected() does not have this
fallback, leading to this bug.

We _could_ try looping through the packs and only reprepare the packs
after a miss, but that change is more involved and has little value.
Since this case is isolated to the case when
opt->check_refs_are_promisor_objects_only is true, we are confident that
we are verifying the refs after downloading new data. This implies that
calling reprepare_packed_git() in advance is not a huge cost compared to
the rest of the operations already made.

Hans Jerry Illikainen [Wed, 4 Mar 2020 11:48:04 +0000 (11:48 +0000)] 
gpg-interface: prefer check_signature() for GPG verification

This commit refactors the use of verify_signed_buffer() outside of
gpg-interface.c to use check_signature() instead.  It also turns
verify_signed_buffer() into a file-local function since it's now only
invoked internally by check_signature().

There were previously two globally scoped functions used in different
parts of Git to perform GPG signature verification:
verify_signed_buffer() and check_signature().  Now only
check_signature() is used.

The verify_signed_buffer() function doesn't guard against duplicate
signatures as described by Michał Górny [1].  Instead it only ensures a
non-erroneous exit code from GPG and the presence of at least one
GOODSIG status field.  This stands in contrast with check_signature()
that returns an error if more than one signature is encountered.

The lower degree of verification makes the use of verify_signed_buffer()
problematic if callers don't parse and validate the various parts of the
GPG status message themselves.  And processing these messages seems like
a task that should be reserved to gpg-interface.c with the function
check_signature().

Furthermore, the use of verify_signed_buffer() makes it difficult to
introduce new functionality that relies on the content of the GPG status
lines.

Now all operations that does signature verification share a single entry
point to gpg-interface.c.  This makes it easier to propagate changed or
additional functionality in GPG signature verification to all parts of
Git, without having odd edge-cases that don't perform the same degree of
verification.

4 years agot: increase test coverage of signature verification output
Hans Jerry Illikainen [Wed, 4 Mar 2020 11:48:03 +0000 (11:48 +0000)] 
t: increase test coverage of signature verification output

There weren't any tests for unsuccessful signature verification of
signed merge tags shown in 'git log'.  There also weren't any tests for
the GPG output from 'git fmt-merge-msg'.  This was noticed while
investigating a buggy refactor that slipped through the test suite; see
commit 72b006f4bfd30b7c5037c163efaf279ab65bea9c.

This commit adds signature verification tests to the 'log' and
'fmt-merge-msg' builtins.

Thanks to Linus Torvalds for reporting and finding the (now reverted)
commit that introduced the regression.

Note that the "log --show-signature for merged tag with GPG failure"
test case is really hacky.  It relies on an implementation detail of
verify_signed_buffer() -- namely, it assumes that the signature is
written to a temporary file whose path is under TMPDIR.

The rationale for that test case is to check whether the code path that
yields the "No signature" message is reachable on failure.  The
functionality in log-tree.c that may show this message does some
pre-parsing of a possible signature that prevents the GPG interface from
being invoked if a signature is actually missing.  And I haven't been
able to construct a signature that both 1. satisfies that
pre-processing, and 2. causes GPG to fail without any sort of output on
stderr along the lines of "this is a bogus/corrupt/... signature" (the
"No signature" message should only be shown if GPG produce no output).

t6022, t6046: fix flaky files-are-updated checks

Several tests wanted to verify that files were actually modified by a
merge, which it would do by checking that the mtime was updated.  In
order to avoid problems with the merge completing so fast that the mtime
at the beginning and end of the operation was the same, these tests
would first set the mtime of a file to something "old".  This "old"
value was usually determined as current system clock minus one second,
truncated to the nearest integer.  Unfortunately, it appears the system
clock and filesystem clock are different and comparing across the two
runs into race problems resulting in flaky tests.

From https://stackoverflow.com/questions/14392975/timestamp-accuracy-on-ext4-sub-millsecond:

    date will call the gettimeofday system call which will always return
    the most accurate time available based on the cached kernel time,
    adjusted by the CPU cycle time if available to give nanosecond
    resolution. The timestamps stored in the file system however, are
    only based on the cached kernel time. ie The time calculated at the
    last timer interrupt.

and from https://apenwarr.ca/log/20181113:

    Does mtime get set to >= the current time?

    No, this depends on clock granularity. For example, gettimeofday()
    can return times in microseconds on my system, but ext4 rounds
    timestamps down to the previous ~10ms (but not exactly 10ms)
    increment, with the surprising result that a newly-created file is
    almost always created in the past:

      $ python -c "
      import os, time
      t0 = time.time()
      open('testfile', 'w').close()
      print os.stat('testfile').st_mtime - t0
      "

      -0.00234484672546

So, instead of trying to compare across what are effectively two
different clocks, just avoid using the system clock.  Any new updates to
files have to give an mtime at least as big as what is already in the
file, so we could define "old" as one second before the mtime found in
the file before the merge starts.  But, to avoid problems with leap
seconds, ntp updates, filesystems that only provide two second
resolution, and other such weirdness, let's just pick an hour before the
mtime found in the file before the merge starts.

Also, clarify in one test where we check the mtime of different files
that it really was intentional.  I totally forgot the reasons for that
and assumed it was a bug when asked.
