A handful of code paths that started using batched ref update API
(after Git 2.51 or so) lost detailed error output, which have been
corrected.
* kn/ref-batch-output-error-reporting-fix:
fetch: delay user information post committing of transaction
receive-pack: utilize rejected ref error details
fetch: utilize rejected ref error details
update-ref: utilize rejected error details if available
refs: add rejection detail to the callback function
refs: skip to next ref when current ref is rejected
"git replay" is taught to drop commits that become empty (not the
ones that are empty in the original).
* pw/replay-drop-empty:
replay: drop commits that become empty
"git history" history rewriting UI.
* ps/history:
builtin/history: implement "reword" subcommand
builtin: add new "history" command
wt-status: provide function to expose status for trees
replay: support updating detached HEAD
replay: support empty commit ranges
replay: small set of cleanups
builtin/replay: move core logic into "libgit.a"
builtin/replay: extract core logic to replay revisions
In Git 2.50 and earlier, we would display failure codes and error
message as part of the status display:
$ git fetch . v1.0.0:refs/heads/foo
error: cannot update ref 'refs/heads/foo': trying to write non-commit object f665776185 to branch 'refs/heads/foo'
From .
! [new tag] v1.0.0 -> foo (unable to update local ref)
With the addition of batched updates, this information is no longer
shown to the user:
$ git fetch . v1.0.0:refs/heads/foo
From .
* [new tag] v1.0.0 -> foo
error: cannot update ref 'refs/heads/foo': trying to write non-commit object f665776185 to branch 'refs/heads/foo'
Since reference updates are batched and processed together at the end,
information around the outcome is not available during individual
reference parsing.
To overcome this, collate and delay the output to the end. Introduce
`ref_update_display_info` which will hold individual update's
information and also whether the update failed or succeeded. This
finally allows us to iterate over all such updates and print them to the
user.
Using an dynamic array and strmap does add some overhead to
'git-fetch(1)', but from benchmarking this seems to be not too bad:
Benchmark 1: fetch: many refs (refformat = files, refcount = 1000, revision = master)
Time (mean ± σ): 42.6 ms ± 1.2 ms [User: 13.1 ms, System: 29.8 ms]
Range (min … max): 40.1 ms … 45.8 ms 47 runs
Benchmark 2: fetch: many refs (refformat = files, refcount = 1000, revision = HEAD)
Time (mean ± σ): 43.1 ms ± 1.2 ms [User: 12.7 ms, System: 30.7 ms]
Range (min … max): 40.5 ms … 45.8 ms 48 runs
Summary
fetch: many refs (refformat = files, refcount = 1000, revision = master) ran
1.01 ± 0.04 times faster than fetch: many refs (refformat = files, refcount = 1000, revision = HEAD)
Another approach would be to move the status printing logic to be
handled post the transaction being committed. That however would require
adding an iterator to the ref transaction that tracks both the outcome
(success/failure) and the original refspec information for each update,
which is more involved infrastructure work compared to the strmap
approach here.

In 9d2962a7c4 (receive-pack: use batched reference updates, 2025-05-19),
git-receive-pack(1) switched to using batched reference updates. This also
introduced a regression wherein instead of providing detailed error
messages for failed referenced updates, the users were provided generic
error messages based on the error type.
Now that the updates also contain detailed error message, propagate
those to the client via 'rp_error'. The detailed error messages can be
very verbose, for e.g. in the files backend, when trying to write a
non-commit object to a branch, you would see:
! [remote rejected] 3eaec9ccf3a53f168362a6b3fdeb73426fb9813d ->
branch (cannot update ref 'refs/heads/branch': trying to write
non-commit object 3eaec9ccf3a53f168362a6b3fdeb73426fb9813d to branch
'refs/heads/branch')
Here the refname is repeated multiple times due to how error messages
are propagated and filled over the code stack. This potentially can be
cleaned up in a future commit.

When git-update-ref(1) received the '--update-ref' flag, the error
details generated in the refs namespace wasn't propagated with failed
updates. Instead only an error code pertaining to the type of rejection
was noted.
This missed detailed error message which the user can act upon. The
previous commits added the required code to propagate these detailed
error messages from the refs namespace. Now that additional details are
available, let's output this additional details to stderr. This allows
users to have additional information over the already present machine
parsable output.
While we're here, improve the existing tests for the machine parsable
output by checking for the entire output string and not just the
rejection reason.

The previous commit started storing the rejection details alongside the
error code for rejected updates. Pass this along to the callback
function `ref_transaction_for_each_rejected_update()`. Currently the
field is unused, but will be integrated in the upcoming commits.

In `refs_verify_refnames_available()` we have two nested loops: the
outer loop iterates over all references to check, while the inner loop
checks for filesystem conflicts for a given ref by breaking down its
path.
With batched updates, when we detect a filesystem conflict, we mark the
update as rejected and execute 'continue'. However, this only skips to
the next iteration of the inner loop, not the outer loop as intended.
This causes the same reference to be repeatedly rejected. Fix this by
using a goto statement to skip to the next reference in the outer loop.

git-gui: mark *.po files at any directory level as UTF-8

git-gui i18n: Update Bulgarian translation (557t)
When a commit is viewed in Gitk that changes a file in po/glossary, the
patch text shows mojibake instead of correctly decoded UTF-8 text.
Gitk retrieves the encoding attribute to decide how to treat the bytes
that make up the patch text. There is an attribute definition that all
files are US-ASCII, and a later attribute definition overrides this.
But the override, which specifies UTF-8, applies only to *.po files in
directory po/ and does not apply to subdirectories.
Widen the pattern to apply to all directory levels.

The 'shallow since with commit graph and already-seen commit”
test uses a convoluted here-doc that combines manual input
construction with packetize, echo and embedded Git commands.
This structure hides failures from the git commands,
as their exit codes are suppressed inside echo command
substitution and being on the upstream side of pipes.
Instead of using here-doc to construct the pack
protocol that is directly sent to the
'git upload-pack' command being tested,
capture the outputs of the git commands upfront
and use the 'test-tool pkt-line pack'
tool to construct the input in a temporary file,
and then feed it to the command.
This has a few advantages:
* Executing the git commands outside the here-doc
avoids suppressing their exit codes and makes
debugging easier.
* It removes the need to manually count and
manage pkt-line lengths to keep in line with
the v2 protocol, as the tool handles this internally.
