pack-objects: turn off bitmaps when we split packsJeff King Fri, 17 Oct 2014 01:11:43 +0000 (21:11 -0400)

pack-objects: turn off bitmaps when we split packs

If a pack.packSizeLimit is set, we may split the pack data
across multiple packfiles. This means we cannot generate
.bitmap files, as they require that all of the reachable
objects are in the same pack. We check that condition when
we are generating the list of objects to pack (and disable
bitmaps if we are not packing everything), but we forgot to
update it when we notice that we needed to split (which
doesn't happen until the actual write phase).

The resulting bitmaps are quite bogus (they mention entries
that do not exist in the pack!) and can cause a fetch or
push to send insufficient objects.

ref_transaction_commit: bail out on failure to remove... Jonathan Nieder Fri, 29 Aug 2014 00:01:35 +0000 (17:01 -0700)

ref_transaction_commit: bail out on failure to remove a ref

When removal of a loose or packed ref fails, bail out instead of
trying to finish the transaction. This way, a single error message
can be printed (instead of multiple messages being concatenated by
mistake) and the operator can try to solve the underlying problem
before there is a chance to muck things up even more.

In particular, when git fails to remove a ref, git goes on to try to
delete the reflog. Exiting early lets us keep the reflog.

When git succeeds in deleting a ref A and fails to remove a ref B, it
goes on to try to delete both reflogs. It would be better to just
remove the reflog for A, but that would be a more invasive change.
Failing early means we keep both reflogs, which puts the operator in a
good position to understand the problem and recover.

A long term goal is to avoid these problems altogether and roll back
the transaction on failure. That kind of transactionality will have
to wait for a later series (the plan for which is to make all
destructive work happen in a single update of the packed-refs file).

refs.c: do not permit err == NULLJonathan Nieder Thu, 28 Aug 2014 23:42:37 +0000 (16:42 -0700)

refs.c: do not permit err == NULL

Some functions that take a strbuf argument to append an error treat
!err as an indication that the message should be suppressed (e.g.,
ref_update_reject_duplicates). Others write the message to stderr on
!err (e.g., repack_without_refs). Others crash (e.g.,
ref_transaction_update).

Some of these behaviors are for historical reasons and others were
accidents. Luckily no callers pass err == NULL any more. Simplify
by consistently requiring the strbuf argument.

remote rm/prune: print a message when writing packed... Ronnie Sahlberg Thu, 11 Sep 2014 15:42:57 +0000 (08:42 -0700)

remote rm/prune: print a message when writing packed-refs fails

Until v2.1.0-rc0~22^2~11 (refs.c: add an err argument to
repack_without_refs, 2014-06-20), repack_without_refs forgot to
provide an error message when commit_packed_refs fails. Even today,
it only provides a message for callers that pass a non-NULL err
parameter. Internal callers in refs.c pass non-NULL err but
"git remote" does not.

That means that "git remote rm" and "git remote prune" can fail
without printing a message about why. Fix them by passing in a
non-NULL err parameter and printing the returned message.

This is the last caller to a ref handling function passing err ==
NULL. A later patch can drop support for err == NULL, avoiding such
problems in the future.

refs.c: allow listing and deleting badly named refsRonnie Sahlberg Wed, 3 Sep 2014 18:45:43 +0000 (11:45 -0700)

refs.c: allow listing and deleting badly named refs

We currently do not handle badly named refs well:

$ cp .git/refs/heads/master .git/refs/heads/master.....@\*@\\.
$ git branch
fatal: Reference has invalid format: 'refs/heads/master.....@*@\.'
$ git branch -D master.....@\*@\\.
error: branch 'master.....@*@\.' not found.

Users cannot recover from a badly named ref without manually finding
and deleting the loose ref file or appropriate line in packed-refs.
Making that easier will make it easier to tweak the ref naming rules
in the future, for example to forbid shell metacharacters like '`'
and '"', without putting people in a state that is hard to get out of.

So allow "branch --list" to show these refs and allow "branch -d/-D"
and "update-ref -d" to delete them. Other commands (for example to
rename refs) will continue to not handle these refs but can be changed
in later patches.

Details:

In resolving functions, refuse to resolve refs that don't pass the
git-check-ref-format(1) check unless the new RESOLVE_REF_ALLOW_BAD_NAME
flag is passed. Even with RESOLVE_REF_ALLOW_BAD_NAME, refuse to
resolve refs that escape the refs/ directory and do not match the
pattern [A-Z_]* (think "HEAD" and "MERGE_HEAD").

In locking functions, refuse to act on badly named refs unless they
are being deleted and either are in the refs/ directory or match [A-Z_]*.

Just like other invalid refs, flag resolved, badly named refs with the
REF_ISBROKEN flag, treat them as resolving to null_sha1, and skip them
in all iteration functions except for for_each_rawref.

Flag badly named refs (but not symrefs pointing to badly named refs)
with a REF_BAD_NAME flag to make it easier for future callers to
notice and handle them specially. For example, in a later patch
for-each-ref will use this flag to detect refs whose names can confuse
callers parsing for-each-ref output.

In the transaction API, refuse to create or update badly named refs,
but allow deleting them (unless they try to escape refs/ and don't match
[A-Z_]*).

There's no straightforward way to grep for all tests dealing with

packed-ref cache: forbid dot-components in refnames

Since v1.7.9-rc1~10^2 (write_head_info(): handle "extra refs" locally,
2012-01-06), this trick to keep track of ".have" refs that are only
valid on the wire and not on the filesystem is not needed any more.

Simplify by removing support for the REFNAME_DOT_COMPONENT flag.

This means we'll be slightly stricter with invalid refs found in a
packed-refs file or during clone. read_loose_refs() already checks
for and skips refnames with .components so it is not affected.

branch -d: simplify by using RESOLVE_REF_READINGRonnie Sahlberg Thu, 11 Sep 2014 17:34:36 +0000 (10:34 -0700)

branch -d: simplify by using RESOLVE_REF_READING

When "git branch -d" reads the branch it is about to delete, it used
to avoid passing the RESOLVE_REF_READING ('treat missing ref as
error') flag because a symref pointing to a nonexistent ref would show
up as missing instead of as something that could be deleted. To check
if a ref is actually missing, we then check

- is it a symref?
- if not, did it resolve to null_sha1?

Now we pass RESOLVE_REF_NO_RECURSE and the correct information is
returned for a symref even when it points to a missing ref. Simplify
by relying on RESOLVE_REF_READING.

No functional change intended.

branch -d: avoid repeated symref resolutionJonathan Nieder Thu, 11 Sep 2014 01:22:48 +0000 (18:22 -0700)

branch -d: avoid repeated symref resolution

If a repository gets in a broken state with too much symref nesting,
it cannot be repaired with "git branch -d":

$ git symbolic-ref refs/heads/nonsense refs/heads/nonsense
$ git branch -d nonsense
error: branch 'nonsense' not found.

Worse, "git update-ref --no-deref -d" doesn't work for such repairs
either:

$ git update-ref -d refs/heads/nonsense
error: unable to resolve reference refs/heads/nonsense: Too many levels of symbolic links

Fix both by teaching resolve_ref_unsafe a new RESOLVE_REF_NO_RECURSE
flag and passing it when appropriate.

Callers can still read the value of a symref (for example to print a
message about it) with that flag set --- resolve_ref_unsafe will
resolve one level of symrefs and stop there.

reflog test: test interaction with detached HEAD

A proposed patch produced broken HEAD reflog entries when checking out
anything other than a branch. The testsuite still passed, so it took
a few days for the bug to be noticed.

Add tests checking the content of the reflog after detaching and
reattaching HEAD so we don't have to rely on manual testing to catch
such problems in the future.

resolve_ref_unsafe takes a boolean argument for reading (a nonexistent ref
resolves successfully for writing but not for reading). Change this to be

we want this behaviour.

While at it, swap two of the arguments in the function to put output

refs.c: ref_transaction_commit: distinguish name conflicts from other errors

In _commit, ENOTDIR can happen in the call to lock_ref_sha1_basic, either
when we lstat the new refname or if the name checking function reports that
the same type of conflict happened. In both cases, it means that we can not
create the new ref due to a name conflict.

Start defining specific return codes for _commit. TRANSACTION_NAME_CONFLICT
refers to a failure to create a ref due to a name conflict with another ref.
TRANSACTION_GENERIC_ERROR is for all other errors.

When "git fetch" is creating refs, name conflicts differ from other errors in
that they are likely to be resolved by running "git remote prune <remote>".
"git fetch" currently inspects errno to decide whether to give that advice.
Once it switches to the transaction API, it can check for
TRANSACTION_NAME_CONFLICT instead.

refs.c: pass a list of names to skip to is_refname_available

Change is_refname_available to take a list of strings to exclude when
checking for conflicts instead of just one single name. We can already
exclude a single name for the sake of renames. This generalizes that support.

ref_transaction_commit already tracks a set of refs that are being deleted
in an array. This array is then used to exclude refs from being written to
the packed-refs file. At some stage we will want to change this array to a
struct string_list and then we can pass it to is_refname_available via the
call to lock_ref_sha1_basic. That will allow us to perform transactions
that perform multiple renames as long as there are no conflicts within the
starting or ending state.

For example, that would allow a single transaction that contains two
renames that are both individually conflicting:

m -> n/n
n -> m/m

refs.c: refuse to lock badly named refs in lock_ref_sha1_basic

Move the check for check_refname_format from lock_any_ref_for_update to
lock_ref_sha1_basic. At some later stage we will get rid of
lock_any_ref_for_update completely. This has no visible impact to callers
except for the inability to lock badly named refs, which is not possible
today already for other reasons.(*)

Keep lock_any_ref_for_update as a no-op wrapper. It is the public facing
version of this interface and keeping it as a separate function will make
it easier to experiment with the internal lock_ref_sha1_basic signature.

(*) For example, if lock_ref_sha1_basic checks the refname format and
refuses to lock badly named refs, it will not be possible to delete
such refs because the first step of deletion is to lock the ref. We
currently already fail in that case because these refs are not recognized
to exist:

$ cp .git/refs/heads/master .git/refs/heads/echo...\*\*
$ git branch -D .git/refs/heads/echo...\*\*
error: branch '.git/refs/heads/echo...**' not found.

This has been broken for a while. Later patches in the series will start
repairing the handling of badly named refs.

mv test: recreate mod/ directory instead of relying... Jonathan Nieder Wed, 10 Sep 2014 21:01:46 +0000 (14:01 -0700)

mv test: recreate mod/ directory instead of relying on stale copy

The tests for 'git mv moves a submodule' functionality often run
commands like

git mv sub mod/sub

to move a submodule into a subdirectory. Just like plain /bin/mv,
this is supposed to succeed if the mod/ parent directory exists
and fail if it doesn't exist.

Usually these tests mkdir the parent directory beforehand, but some
instead rely on it being left behind by previous tests.

More precisely, when 'git reset --hard' tries to move to a state where
mod/sub is not present any more, it would perform the following
operations:

rmdir("mod/sub")
rmdir("mod")

The first fails with ENOENT because the test script removed mod/sub
with "rm -rf" already, so 'reset --hard' doesn't bother to move on to
the second, and the mod/ directory is kept around.

Better to explicitly remove and re-create the mod/ directory so later
tests don't have to depend on the directory left behind by the earlier
ones at all (making it easier to rearrange or skip some tests in the
file or to tweak 'reset --hard' behavior without breaking unrelated
tests).

Noticed while testing a patch that fixes the reset --hard behavior
described above.

color_parse: do not mention variable name in error... Jeff King Tue, 7 Oct 2014 19:33:09 +0000 (15:33 -0400)

color_parse: do not mention variable name in error message

Originally the color-parsing function was used only for
config variables. It made sense to pass the variable name so
that the die() message could be something like:

$ git -c color.branch.plain=bogus branch
fatal: bad color value 'bogus' for variable 'color.branch.plain'

These days we call it in other contexts, and the resulting
error messages are a little confusing:

$ git log --pretty='%C(bogus)'
fatal: bad color value 'bogus' for variable '--pretty format'

$ git config --get-color foo.bar bogus
fatal: bad color value 'bogus' for variable 'command line'

This patch teaches color_parse to complain only about the
value, and then return an error code. Config callers can
then propagate that up to the config parser, which mentions
the variable name. Other callers can provide a custom
message. After this patch these three cases now look like:

$ git -c color.branch.plain=bogus branch
error: invalid color value: bogus
fatal: unable to parse 'color.branch.plain' from command-line config

$ git log --pretty='%C(bogus)'
error: invalid color value: bogus
fatal: unable to parse --pretty format

$ git config --get-color foo.bar bogus
error: invalid color value: bogus
fatal: unable to parse default color value

pass config slots as pointers instead of offsetsJonathan Nieder Tue, 7 Oct 2014 19:16:57 +0000 (15:16 -0400)

pass config slots as pointers instead of offsets

Many config-parsing helpers, like parse_branch_color_slot,
take the name of a config variable and an offset to the
"slot" name (e.g., "color.branch.plain" is passed along with
"13" to effectively pass "plain"). This is leftover from the
time that these functions would die() on error, and would
want the full variable name for error reporting.

These days they do not use the full variable name at all.
Passing a single pointer to the slot name is more natural,
and lets us more easily adjust the callers to use skip_prefix
to avoid manually writing offset numbers.

This is effectively a continuation of 9e1a5eb, which did the
same for parse_diff_color_slot. This patch covers all of the
remaining similar constructs.

test-lib.sh: support -x option for shell-tracing

Usually running a test under "-v" makes it clear which
command is failing. However, sometimes it can be useful to
also see a complete trace of the shell commands being run in
the test. You can do so without any support from the test
suite by running "sh -x tXXXX-foo.sh". However, this
produces quite a large bit of output, as we see a trace of
the entire test suite.

This patch instead introduces a "-x" option to the test
scripts (i.e., "./tXXXX-foo.sh -x"). When enabled, this
turns on "set -x" only for the tests themselves. This can
still be a bit verbose, but should keep things to a more
manageable level. You can even use "--verbose-only" to see
the trace only for a specific test.

The implementation is a little invasive. We turn on the "set
-x" inside the "eval" of the test code. This lets the eval
itself avoid being reported in the trace (which would be
long, and redundant with the verbose listing we already
showed). And then after the eval runs, we do some trickery
with stderr to avoid showing the "set +x" to the user.

We also show traces for test_cleanup functions (since they
can impact the test outcome, too). However, we do avoid
running the noop ":" cleanup (the default if the test does
not use test_cleanup at all), as it creates unnecessary
noise in the "set -x" output.

This patch adds the "git interpret-trailers" command.
This command uses the previously added process_trailers()
function in trailer.c.

trailer: read and process config information

Read the configuration to get trailer information, and then process
it and store it in a doubly linked list.

The config information is stored in the list whose first item is
pointed to by:

static struct trailer_item *first_conf_item;

trailer: process trailers from input message and argumentsChristian Couder Mon, 13 Oct 2014 18:16:24 +0000 (20:16 +0200)

trailer: process trailers from input message and arguments

Implement the logic to process trailers from the input message
and from arguments.

At the beginning trailers from the input message are in their
own "in_tok" doubly linked list, and trailers from arguments
are in their own "arg_tok" doubly linked list.

The lists are traversed and when an "arg_tok" should be "applied",
it is removed from its list and inserted into the "in_tok" list.

trailer: add data structures and basic functions

We will use a doubly linked list to store all information
about trailers and their configuration.

This way we can easily remove or add trailers to or from
trailer lists while traversing the lists in either direction.

Documentation: fix mismatched delimiters in git-imap-send

The documentation for git-imap-send uses block delimiters with
mismatched lengths, which Asciidoctor doesn't support. As a result, the
page is misrendered. Adjust the delimiters so that they are of the same
length.

Documentation: adjust document title underlining

AsciiDoc specification states that in two-line titles, the title
underline has to be the same length as the title text, plus or minus two
characters. Asciidoctor, however, requires that this must be plus or
minus one character. Adjust the underlines to be the same length as the
title text to improve compatibility.

receive-pack: plug minor memory leak in unpack()

The argv_array used in unpack() is never freed. Instead of adding
explicit calls to argv_array_clear() use the args member of struct
child_process and let run_command() and friends clean up for us.

t5304: use helper to report failure of "test foo = bar"

For small outputs, we sometimes use:

test "$(some_cmd)" = "something we expect"

instead of a full test_cmp. The downside of this is that
when it fails, there is no output at all from the script.
Let's introduce a small helper to make tests easier to
debug.

t5304: use test_path_is_* instead of "test -f"

This is slightly more robust (checking "! test -f" would not
notice a directory of the same name, though that is not
likely to happen here). It also makes debugging easier, as
the test script will output a message on failure.
