grep: add -r/--[no-]recursiveRené Scharfe Mon, 1 Oct 2018 19:15:57 +0000 (21:15 +0200)

grep: add -r/--[no-]recursive

Recognize -r and --recursive as synonyms for --max-depth=-1 for
compatibility with GNU grep; it's still the default for git grep.

This also adds --no-recursive as synonym for --max-depth=0 for free,
which is welcome for completeness and consistency.

Fix the description for --max-depth, while we're at it -- negative
values other than -1 actually disable recursion, i.e. they are
equivalent to --max-depth=0.

commit-reach: fix memory and flag leaksDerrick Stolee Fri, 21 Sep 2018 15:05:27 +0000 (08:05 -0700)

commit-reach: fix memory and flag leaks

The can_all_from_reach_with_flag() method uses 'assign_flag' as a
value we can use to mark objects temporarily during our commit walk.
The intent is that these flags are removed from all objects before
returning. However, this is not the case.

The 'from' array could also contain objects that are not commits, and
we mark those objects with 'assign_flag'. Add a loop to the 'cleanup'
section that removes these markers.

Also, we forgot to free() the memory for 'list', so add that to the
'cleanup' section.

commit-reach: properly peel tagsDerrick Stolee Fri, 21 Sep 2018 15:05:26 +0000 (08:05 -0700)

commit-reach: properly peel tags

The can_all_from_reach_with_flag() algorithm was refactored in 4fbcca4e
"commit-reach: make can_all_from_reach... linear" but incorrectly
assumed that all objects provided were commits. During a fetch
negotiation, ok_to_give_up() in upload-pack.c may provide unpeeled tags
to the 'from' array. The current code creates a segfault.

Add a direct call to can_all_from_reach_with_flag() in 'test-tool reach'
and add a test in t6600-test-reach.sh that demonstrates this segfault.

Correct the issue by peeling tags when investigating the initial list
of objects in the 'from' array.

add: do not accept pathspec magic 'attr'Nguyễn Thái Ngọc Duy Tue, 18 Sep 2018 17:31:59 +0000 (19:31 +0200)

add: do not accept pathspec magic 'attr'

Commit b0db704652 (pathspec: allow querying for attributes -
2017-03-13) adds new pathspec magic 'attr' but only with
match_pathspec(). "git add" has some pathspec related code that still
does not know about 'attr' and will bail out:

$ git add ':(attr:foo)'
fatal: BUG:dir.c:1584: unsupported magic 40

A better solution would be making this code support 'attr'. But I
don't know how much work is needed (I'm not familiar with this new
magic). For now, let's simply reject this magic with a friendlier
message:

$ git add ':(attr:foo)'
fatal: :(attr:foo): pathspec magic not supported by this command: 'attr'

Update t6135 so that the expected error message is from the
"graceful" rejection codepath, not "oops, we were supposed to reject
the request to trigger this magic" codepath.

The rules used by "git push" and "git fetch" to determine if a ref

Merge branch 'nd/unpack-trees-with-cache-tree'

The unpack_trees() API used in checking out a branch and merging
walks one or more trees along with the index. When the cache-tree
in the index tells us that we are walking a tree whose flattened
contents is known (i.e. matches a span in the index), as linearly
scanning a span in the index is much more efficient than having to
open tree objects recursively and listing their entries, the walk
can be optimized, which is done in this topic.

linear-assignment: fix potential out of bounds memory... Thomas Gummerer Thu, 13 Sep 2018 22:38:34 +0000 (23:38 +0100)

linear-assignment: fix potential out of bounds memory access

Currently the 'compute_assignment()' function may read memory out
of bounds, even if used correctly. Namely this happens when we only
have one column. In that case we try to calculate the initial
minimum cost using '!j1' as column in the reduction transfer code.
That in turn causes us to try and get the cost from column 1 in the
cost matrix, which does not exist, and thus results in an out of
bounds memory read.

In the original paper [1], the example code initializes that minimum
cost to "infinite". We could emulate something similar by setting the
minimum cost to INT_MAX, which would result in the same minimum cost
as the current algorithm, as we'd always go into the if condition at
least once, except when we only have one column, and column_count thus
equals 1.

If column_count does equal 1, the condition in the loop would always
be false, and we'd end up with a minimum of INT_MAX, which may lead to
integer overflows later in the algorithm.

For a column count of 1, we however do not even really need to go
through the whole algorithm. A column count of 1 means that there's
no possible assignments, and we can just zero out the column2row and
row2column arrays, and return early from the function, while keeping
the reduction transfer part of the function the same as it is
currently.

Another solution would be to just not call the 'compute_assignment()'
function from the range diff code in this case, however it's better to
make the compute_assignment function more robust, so future callers
don't run into this potential problem.

Note that the test only fails under valgrind on Linux, but the same
command has been reported to segfault on Mac OS.

fetch-object: set exact_oid when fetching

fetch_objects() currently does not set exact_oid in struct ref when
invoking transport_fetch_refs(). If the server supports ref-in-want,
fetch_pack() uses this field to determine whether a wanted ref should be
requested as a "want-ref" line or a "want" line; without the setting of
exact_oid, the wrong line will be sent.

Set exact_oid, so that the correct line is sent.

sequencer: fix --allow-empty-message behavior, make it smarter

In commit b00bf1c9a8dd ("git-rebase: make --allow-empty-message the
default", 2018-06-27), several arguments were given for transplanting
empty commits without halting and asking the user for confirmation on
each commit. These arguments were incomplete because the logic clearly
assumed the only cases under consideration were transplanting of commits
with empty messages (see the comment about "There are two sources for
commits with empty messages). It didn't discuss or even consider
rewords, squashes, etc. where the user is explicitly asked for a new
commit message and provides an empty one. (My bad, I totally should
have thought about that at the time, but just didn't.)

Rewords and squashes are significantly different, though, as described
by SZEDER:

Let's suppose you start an interactive rebase, choose a commit to
squash, save the instruction sheet, rebase fires up your editor, and
then you notice that you mistakenly chose the wrong commit to
squash. What do you do, how do you abort?

Before [that commit] you could clear the commit message, exit the
editor, and then rebase would say "Aborting commit due to empty
commit message.", and you get to run 'git rebase --abort', and start
over.

But [since that commit, ...] saving the commit message as is would
let rebase continue and create a bunch of unnecessary objects, and
then you would have to use the reflog to return to the pre-rebase
state.

Also, he states:

The instructions in the commit message template, which is shown for
'reword' and 'squash', too, still say...

# Please enter the commit message for your changes. Lines starting
# with '#' will be ignored, and an empty message aborts the commit.

These are sound arguments that when editing commit messages during a
sequencer operation, that if the commit message is empty then the
operation should halt and ask the user to correct. The arguments in
commit b00bf1c9a8dd (referenced above) still apply when transplanting
previously created commits with empty commit messages, so the sequencer
should not halt for those.

Furthermore, all rationale so far applies equally for cherry-pick as for
rebase. Therefore, make the code default to --allow-empty-message when
transplanting an existing commit, and to default to halting when the
user is asked to edit a commit message and provides an empty one -- for
both rebase and cherry-pick.

update-ref: allow --no-deref with --stdinElijah Newren Wed, 5 Sep 2018 17:25:50 +0000 (10:25 -0700)

update-ref: allow --no-deref with --stdin

If passed both --no-deref and --stdin, update-ref would error out with a
general usage message that did not at all suggest these options were
incompatible. The manpage for update-ref did suggest through its
synopsis line that --no-deref and --stdin were incompatible, but it sadly
also incorrectly suggested that -d and --no-deref were incompatible. So
the help around the --no-deref option is buggy in a few ways.

The --stdin option did provide a different mechanism for avoiding
dereferencing symbolic-refs: adding a line reading
option no-deref
before every other directive in the input. (Technically, if the user
wants to do the extra work of first determining which refs they want to
update or delete are symbolic, then they only need to put the extra
"option no-deref" lines before the updates of those refs. But in some
cases, that's more work than just adding the "option no-deref" before
every other directive.)

It's easier to allow the user to just pass --no-deref along with --stdin
in order to tell update-ref that the user doesn't want any symbolic ref
to be dereferenced. It also makes the update-ref documentation simpler.
Implement that, and update the documentation to match.

rerere: avoid buffer overrun

check_one_conflict() compares `i` to `active_nr` in two places to avoid
buffer overruns, but left out an important third location.

The code did used to have a check here comparing i to active_nr, back
before commit fb70a06da2f1 ("rerere: fix an off-by-one non-bug",

'while' meaning back then that this loop could not have read past the
end of the array, making the check unnecessary and it was removed.
Unfortunately, in commit 5eda906b2873 ("rerere: handle conflicts with
multiple stage #1 entries", 2015-07-24), the 'if' was changed to a
'while' and the check comparing i and active_nr was not re-instated,

of undesired pathspec expansion. This check is done with 'grep' using
the filename on its own as the pattern, which is too loose a pattern,
and would match any occurrences of the filename in the trace output,
not just those as command arguments. E.g. if a developer were to
litter the index handling code with trace_printf()s printing, among
other things, the name of the just processed cache entry, then that
pattern would mistakenly match these as well, and would fail the test.

bad_format and good_format parameters. These ultimately come
from literals, but they still trigger the warning.

Some of these might be fixable (e.g., by passing flags from
which we locally select a format), and might even be worth
fixing (not because of security, but just because it's an
easy mistake to pass the wrong format). But there are other
cases which are likely quite hard to fix (we actually
generate formats in a local buffer in some cases). So let's
punt on that for now and start with -Wformat-security, which
is supposed to catch the most important cases.

string-list: remove unused function print_string_list

A removal of this helper function was proposed 3 years ago [1]; the
function was never used since it was introduced in 2006 back then,
and there is no new callers since. Now time has proven we really do
not need the function.

Merge branch 'mk/http-backend-content-length'

The earlier attempt barfed when given a CONTENT_LENGTH that is
set to an empty string. RFC 3875 is fairly clear that in this
case we should not read any message body, but we've been reading
through to the EOF in previous versions (which did not even pay
attention to the environment variable), so keep that behaviour for
now in this late update.

Revert "Merge branch 'sb/submodule-core-worktree'"

This reverts commit 7e25437d35a70791b345872af202eabfb3e1a8bc, reversing
changes made to 00624d608cc69bd62801c93e74d1ea7a7ddd6598.

v2.19.0-rc0~165^2~1 (submodule: ensure core.worktree is set after
update, 2018-06-18) assumes an "absorbed" submodule layout, where the
submodule's Git directory is in the superproject's .git/modules/
directory and .git in the submodule worktree is a .git file pointing
there. In particular, it uses $GIT_DIR/modules/$name to find the
submodule to find out whether it already has core.worktree set, and it
uses connect_work_tree_and_git_dir if not, resulting in

fatal: could not open sub/.git for writing

The context behind that patch: v2.19.0-rc0~165^2~2 (submodule: unset
core.worktree if no working tree is present, 2018-06-12) unsets
core.worktree when running commands like "git checkout
--recurse-submodules" to switch to a branch without the submodule. If
a user then uses "git checkout --no-recurse-submodules" to switch back
to a branch with the submodule and runs "git submodule update", this
patch is needed to ensure that commands using the submodule directly
are aware of the path to the worktree.

It is late in the release cycle, so revert the whole 3-patch series.
We can try again later for 2.20.

http-backend: allow empty CONTENT_LENGTHMax Kirillov Fri, 7 Sep 2018 03:36:07 +0000 (06:36 +0300)

http-backend: allow empty CONTENT_LENGTH

According to RFC3875, empty environment variable is equivalent to unset,
and for CONTENT_LENGTH it should mean zero body to read.

However, unset CONTENT_LENGTH is also used for chunked encoding to indicate
reading until EOF. At least, the test "large fetch-pack requests can be split
across POSTs" from t5551 starts faliing, if unset or empty CONTENT_LENGTH is
treated as zero length body. So keep the existing behavior as much as possible.

Add a test for the case.

"cette" can be only be used before a word (like in "cette bouteille" for

to use "ceci" in French.
