commit-graph write: add progress output
Before this change the "commit-graph write" command didn't report any
progress. On my machine this command takes more than 10 seconds to
write the graph for linux.git, and around 1m30s on the
2015-04-03-1M-git.git[1] test repository (a test case for a large
monorepository).
Furthermore, since the gc.writeCommitGraph setting was added in
d5d5d7b641 ("gc: automatically write commit-graph files", 2018-06-27),
there was no indication at all from a "git gc" run that anything was
different. This why one of the progress bars being added here uses
start_progress() instead of start_delayed_progress(), so that it's
guaranteed to be seen. E.g. on my tiny 867 commit dotfiles.git
repository:
$ git -c gc.writeCommitGraph=true gc
Enumerating objects: 2821, done.
[...]
Computing commit graph generation numbers: 100% (867/867), done.
On larger repositories, such as linux.git the delayed progress bar(s)
will kick in, and we'll show what's going on instead of, as was
previously happening, printing nothing while we write the graph:
$ git -c gc.writeCommitGraph=true gc
[...]
Annotating commits in commit graph:
1565573, done.
Computing commit graph generation numbers: 100% (782484/782484), done.
Note that here we don't show "Finding commits for commit graph", this
is because under "git gc" we seed the search with the commit
references in the repository, and that set is too small to show any
progress, but would e.g. on a smaller repo such as git.git with
--stdin-commits:
$ git rev-list --all | git -c gc.writeCommitGraph=true write --stdin-commits
Finding commits for commit graph: 100% (162576/162576), done.
Computing commit graph generation numbers: 100% (162576/162576), done.
With --stdin-packs we don't show any estimation of how much is left to
do. This is because we might be processing more than one pack. We
could be less lazy here and show progress, either by detecting that
we're only processing one pack, or by first looping over the packs to
discover how many commits they have. I don't see the point in doing
that work. So instead we get (on 2015-04-03-1M-git.git):
$ echo pack-<HASH>.idx | git -c gc.writeCommitGraph=true --exec-path=$PWD commit-graph write --stdin-packs
Finding commits for commit graph:
13064614, done.
Annotating commits in commit graph:
3001341, done.
Computing commit graph generation numbers: 100% (
1000447/
1000447), done.
No GC mode uses --stdin-packs. It's what they use at Microsoft to
manually compute the generation numbers for their collection of large
packs which are never coalesced.
The reason we need a "report_progress" variable passed down from "git
gc" is so that we don't report this output when we're running in the
process "git gc --auto" detaches from the terminal.
Since we write the commit graph from the "git gc" process itself (as
opposed to what we do with say the "git repack" phase), we'd end up
writing the output to .git/gc.log and reporting it to the user next
time as part of the "The last gc run reported the following[...]"
error, see
329e6e8794 ("gc: save log from daemonized gc --auto and
print it next time", 2015-09-19).
So we must keep track of whether or not we're running in that
demonized mode, and if so print no progress.
See [2] and subsequent replies for a discussion of an approach not
taken in compute_generation_numbers(). I.e. we're saying "Computing
commit graph generation numbers", even though on an established
history we're mostly skipping over all the work we did in the
past. This is similar to the white lie we tell in the "Writing
objects" phase (not all are objects being written).
Always showing progress is considered more important than
accuracy. I.e. on a repository like 2015-04-03-1M-git.git we'd hang
for 6 seconds with no output on the second "git gc" if no changes were
made to any objects in the interim if we'd take the approach in [2].

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.

t: add test functions to translate hash-related values
Add several test functions to make working with various hash-related
values easier.
Add test_oid_init, which loads common hash-related constants and
placeholder object IDs from the newly added files in t/oid-info.
Provide values for these constants for both SHA-1 and SHA-256.
Add test_oid_cache, which accepts data on standard input in the form of
hash-specific key-value pairs that can be looked up later, using the
same format as the files in t/oid-info. Document this format in a
t/oid-info/README directory so that it's easier to use in the future.
Add test_oid, which is used to specify look up a per-hash value
(produced on standard output) based on the key specified as its
argument. Usually the data to be looked up will be a hash-related
constant (such as the size of the hash in binary or hexadecimal), a
well-known or placeholder object ID (such as the all-zeros object ID or
one consisting of "
deadbeef" repeated), or something similar. For these
reasons, test_oid will usually be used within a command substitution.
Consequently, redirect the error output to standard error, since
otherwise it will not be displayed.
Add test_detect_hash, which currently only detects SHA-1, and
test_set_hash, which can be used to set a different hash algorithm for
test purposes. In the future, test_detect_hash will learn to actually
detect the hash depending on how the testsuite is to be run.
Use the local keyword within these functions to avoid overwriting other
shell variables. We have had a test balloon in place for a couple of
releases to catch shells that don't have this keyword and have not
received any reports of failure. Note that the varying usages of local
used here are supported by all common open-source shells supporting the
local keyword.
Test these new functions as part of t0000, which also serves to
demonstrate basic usage of them. In addition, add documentation on how
to format the lookup data and how to use the test functions.
Implement two basic lookup charts, one for common invalid or synthesized
object IDs, and one for various facts about the hash function in use.
Provide versions of the data for both SHA-1 and SHA-256.
Since we use shell variables for storage, names used for lookup can
currently consist only of shell identifier characters. If this is a
problem in the future, we can hash the names before use.

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.

fsck: use oidset instead of oid_array for skipList
Change the implementation of the skipList feature to use oidset
instead of oid_array to store SHA-1s for later lookup.
This list is parsed once on startup by fsck, fetch-pack or
receive-pack depending on the *.skipList config in use. I.e. only once
per invocation, but note that for "clone --recurse-submodules" each
submodule will re-parse the list, in addition to the main project, and
it will be re-parsed when checking .gitmodules blobs, see
fb16287719 ("fsck: check skiplist for object in fsck_blob()",
2018-06-27).
Memory usage is a bit higher, but we don't need to keep track of the
sort order anymore. Embed the oidset into struct fsck_options to make
its ownership clear (no hidden sharing) and avoid unnecessary pointer
indirection.

fsck: use strbuf_getline() to read skiplist file
The buffer is unlikely to contain a NUL character, so printing its
contents using %s in a die() format is unsafe (detected with ASan).
Use an idiomatic strbuf_getline() loop instead, which ensures the buffer
is always NUL-terminated, supports CRLF files as well, accepts files
without a newline after the last line, supports any hash length
automatically, and is shorter.

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

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.

rerere: avoid buffer overrun
check_one_conflict() compares `i` to `active_nr` in two places to avoid

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",

t3701-add-interactive: tighten the check of trace output
The test 'add -p does not expand argument lists' in
't3701-add-interactive.sh', added in
7288e12cce (add--interactive: do
not expand pathspecs with ls-files, 2017-03-14), checks the GIT_TRACE
of 'git add -p' to ensure that the name of a tracked file wasn't
passed around as argument to any of the commands executed as a result
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.
Tighten this 'grep' pattern to only match trace lines that show the
executed commands.

config.mak.dev: add -Wformat-security
We currently build cleanly with -Wformat-security, and it's
a good idea to make sure we continue to do so (since calls
that trigger the warning may be security vulnerabilities).
Note that we cannot use the stronger -Wformat-nonliteral, as
there are case where we are clever with passing around
pointers to string literals. E.g., bisect_rev_setup() takes
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.

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_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.
