Code clean-up by removing a compatibility implementation of a
function we no longer use.
* cb/no-more-gmtime:
compat: remove gmtime
|
|
ccd469450a (date.c: switch to reentrant {gm,local}time_r, 2019-11-28)
removes the only gmtime() call we had and moves to gmtime_r() which
doesn't have the same portability problems.
Remove the compat gmtime code since it is no longer needed, and confirm
by successfull running t4212 in FreeBSD 9.3 amd64 (the oldest I could
get a hold off).
Further work might be needed to ensure 32bit time_t systems (like FreeBSD
i386) will handle correctly the overflows tested in t4212, but that is
orthogonal to this change, and it doesn't change the current behaviour
as neither gmtime() or gmtime_r() will ever return NULL on those systems
because time_t is unsigned.

Teach Git how to prompt the user for a good bug report: reproduction
steps, expected behavior, and actual behavior. Later, Git can learn how
to collect some diagnostic information from the repository.
If users can send us a well-written bug report which contains diagnostic
information we would otherwise need to ask the user for, we can reduce
the number of question-and-answer round trips between the reporter and
the Git contributor.
Users may also wish to send a report like this to their local "Git
expert" if they have put their repository into a state they are confused
by.

Starting in 3ac68a93fd2, help.o began to depend on builtin/branch.o,
builtin/clean.o, and builtin/config.o. This meant that help.o was
unusable outside of the context of the main Git executable.
To make help.o usable by other commands again, move list_config_help()
into builtin/help.c (where it makes sense to assume other builtin libraries
are present).
When command-list.h is included but a member is not used, we start to
hear a compiler warning. Since the config list is generated in a fairly
different way than the command list, and since commands and config
options are semantically different, move the config list into its own
header and move the generator into its own script and build rule.
For reasons explained in 976aaedc (msvc: add a Makefile target to
pre-generate the Visual Studio solution, 2019-07-29), some build
artifacts we consider non-source files cannot be generated in the
Visual Studio environment, and we already have some Makefile tweaks
to help Visual Studio to use generated command-list.h header file.
Do the same to a new generated file, config-list.h, introduced by
this change.

Commit 94a88e2524 (Makefile: avoid running curl-config multiple times,
2020-03-26) put the call to $(CURL_CONFIG) into a "simple" variable
which is expanded immediately, rather than expanding it each time it's
needed. However, that also means that we expand it whenever the Makefile
is parsed, whether we need it or not.
This is wasteful, but also breaks the ci/test-documentation.sh job, as
it does not have curl at all and complains about the extra messages to
stderr. An easy way to see it is just:
$ make CURL_CONFIG=does-not-work check-builtins
make: does-not-work: Command not found
make: does-not-work: Command not found
GIT_VERSION = 2.26.0.108.gb3f3f45f29
make: does-not-work: Command not found
make: does-not-work: Command not found
./check-builtins.sh
We can get the best of both worlds if we're willing to accept a little
Makefile hackery. Courtesy of the article at:
http://make.mad-scientist.net/deferred-simple-variable-expansion/
this patch uses a lazily-evaluated recursive variable which replaces its
contents with an immediately assigned simple one on first use.

We renamed the actual data structure in 910650d2f8 (Rename sha1_array to
oid_array, 2017-03-31), but the file is still called sha1-array. Besides
being slightly confusing, it makes it more annoying to grep for leftover
occurrences of "sha1" in various files, because the header is included
in so many places.
Let's complete the transition by renaming the source and header files
(and fixing up a few comment references).
I kept the "-" in the name, as that seems to be our style; cf.
fc1395f4a4 (sha1_file.c: rename to use dash in file name, 2018-04-10).
We also have oidmap.h and oidset.h without any punctuation, but those
are "struct oidmap" and "struct oidset" in the code. We _could_ make
this "oidarray" to match, but somehow it looks uglier to me because of
the length of "array" (plus it would be a very invasive patch for little
gain).

We add the result of "curl-config --libs" when linking curl programs,
but we never bother calling "curl-config --cflags". Presumably nobody
noticed because:
- a system libcurl installed into /usr/include/curl wouldn't need any
flags ("/usr/include" is already in the search path, and the
#include lines all look <curl/curl.h>, etc).
- using CURLDIR sets up both the includes and the library path
However, if you prefer CURL_CONFIG to CURLDIR, something simple like:
make CURL_CONFIG=/path/to/curl-config
doesn't work. We'd link against the libcurl specified by that program,
but not find its header files when compiling.
Let's invoke "curl-config --cflags" similar to the way we do for
"--libs". Note that we'll feed the result into BASIC_CFLAGS. The rest of
the Makefile doesn't distinguish which files need curl support during
compilation and which do not. That should be OK, though. At most this
should be adding a "-I" directive, and this is how CURLDIR already
behaves. And since we follow the immediate-variable pattern from
CURL_LDFLAGS, we won't accidentally invoke curl-config once per
compilation.

If the user hasn't set the CURL_LDFLAGS Makefile variable, we invoke
curl-config like this:
CURL_LIBCURL += $(shell $(CURL_CONFIG) --libs)
Because the shell function is run when the value is expanded, we invoke
curl-config each time we need to link something (which generally ends up
being four times for a full build).
Instead, let's use an immediate Makefile variable, which only needs
expanding once. We can't combine that with the existing "+=", but since
we only do this when CURL_LDFLAGS is undefined, we can just set that
variable.
That also allows us to simplify our conditional a bit, since both sides
will then put the result into CURL_LIBCURL. While we're touching it,
let's fix the indentation to match the nearby code (we're inside an
outer conditional, so everything else is indented one level).

There are many += lists in the Makefile and, over time, they have gotten
slightly out of ASCII order. Sort all += lists to bring them back in
order.
ASCII sorting was chosen over strict alphabetical order even though, if
we omit file prefixes, the lists aren't sorted in strictly alphabetical
order (e.g. archive.o comes after archive-zip.o instead of before
archive-tar.o). This is intentional because the purpose of maintaining
the sorted list is to ensure line insertions are deterministic. By using
ASCII ordering, it is more easily mechanically reproducible in the
future, such as by using :sort in Vim.
This patch is best viewed with `--color-moved`.

Remove the stash.useBuiltin setting which was added as an escape hatch
to disable the builtin version of stash first released with Git 2.22.
Carrying the legacy version is a maintenance burden, and has in fact
become out of date failing a test since the 2.23 release, without
anyone noticing until now. So users would be getting a hint to fall
back to a potentially buggy version of the tool.
We used to shell out to git config to get the useBuiltin configuration
to avoid changing any global state before spawning legacy-stash.
However that is no longer necessary, so just use the 'git_config'
function to get the setting instead.
Similar to what we've done in d03ebd411c ("rebase: remove the
rebase.useBuiltin setting", 2019-03-18), where we remove the
corresponding setting for rebase, we leave the documentation in place,
so people can refer back to it when searching for it online, and so we
can refer to it in the commit message.

Currently it's very easy for the advice library's callers to miss
checking the visibility step before printing an advice. Also, it makes
more sense for this step to be handled by the advice library.
Add a new advise_if_enabled function that checks the visibility of
advice messages before printing.
Add a new helper advise_enabled to check the visibility of the advice
if the caller needs to carry out complicated processing based on that
value.
A list of advice_settings is added to cache the config variables names
and values, it's intended to replace advice_config[] and the global
variables once we migrate all the callers to use the new APIs.

rebase types
When 46af44b07d (pull --rebase=<type>: allow single-letter abbreviations
for the type, 2018-08-04) landed in Git, it had the side effect that
not only 'pull --rebase=<type>' accepted the single-letter abbreviations
but also the 'pull.rebase' and 'branch.<name>.rebase' configurations.
However, 'git remote rename' did not honor these single-letter
abbreviations when reading the 'branch.*.rebase' configurations.
We now document the single-letter abbreviations and both code places
share a common function to parse the values of 'git pull --rebase=*',
'pull.rebase', and 'branches.*.rebase'.
The only functional change is the handling of the `branch_info::rebase`
value. Before it was an unsigned enum, thus the truth value could be
checked with `branch_info::rebase != 0`. But `enum rebase_type` is
signed, thus the truth value must now be checked with
`branch_info::rebase >= REBASE_TRUE`

* jk/asan-build-fix:
Makefile: use compat regex with SANITIZE=address
|

Recent versions of the gcc and clang Address Sanitizer produce test
failures related to regexec(). This triggers with gcc-10 and clang-8
(but not gcc-9 nor clang-7). Running:
make CC=gcc-10 SANITIZE=address test
results in failures in t4018, t3206, and t4062.
The cause seems to be that when built with ASan, we use a different
version of regexec() than normal. And this version doesn't understand
the REG_STARTEND flag. Here's my evidence supporting that.
The failure in t4062 is an ASan warning:
expecting success of 4062.2 '-G matches':
git diff --name-only -G "^(0{64}){64}$" HEAD^ >out &&

In this case we're looking in a buffer which was mmap'd via
reuse_worktree_file(), and whose size is 4096 bytes. But libasan's
regex tries to look at byte 4097 anyway! If we tweak Git like this:
diff --git a/diff.c b/diff.c

to use a regular buffer (with a trailing NUL) instead of an mmap, then
the complaint goes away.
The other failures are actually diff output with an incorrect funcname

That first regex should match (and is negated, so it should be telling
us _not_ to match "private:"). But it wouldn't if regexec() is looking
at the whole buffer, and not just the length-limited line we've fed to
regexec_buf(). So this is consistent again with REG_STARTEND being
ignored.
The correct output (compiling without ASan, or gcc-9 with Asan) looks
like this:
warning: regexec matched:

So it really does seem like libasan's regex engine is ignoring
REG_STARTEND. We should be able to work around it by compiling with
NO_REGEX, which would use our local regexec(). But to make matters even
more interesting, this isn't enough by itself.
Because ASan has support from the compiler, it doesn't seem to intercept
our call to regexec() at the dynamic library level. It actually
recognizes when we are compiling a call to regexec() and replaces it
with ASan-specific code at that point. And unlike most of our other
compat code, where we might have git_mmap() or similar, the actual
symbol name in the compiled compat/regex code is regexec(). So just
compiling with NO_REGEX isn't enough; we still end up in libasan!
We can work around that by having the preprocessor replace regexec with
git_regexec (both in the callers and in the actual implementation), and
we truly end up with a call to our custom regex code, even when
compiling with ASan. That's probably a good thing to do anyway, as it
means anybody looking at the symbols later (e.g., in a debugger) would
have a better indication of which function is which. So we'll do the
same for the other common regex functions (even though just regexec() is
enough to fix this ASan problem).

Correct unintentional duplication(s) of words, such as "the the",
and "can can" etc.
The changes are only applied to cases where it's fixing what is clearly
wrong or prone to misunderstanding, as suggested by the reviewers.

When ebb7baf0 ("Makefile: add a hdr-check target", 2018-09-19)
implemented hdr-check target, it wanted to leave some header files
exempt from the stricter check the target implements, and added
GEN_HDRS macro.
This however is probably a bad move for two reasons:
- If we value the header cleanliness check, we eventually want to
teach our header generating scripts to produce clean headers.
Keeping the blanket "generated headers can be left as dirty as we
want" exception does not nudge us in the right direction.
- There is a list of generated header files, GENERATED_H, which is
used to keep track of dependencies. Presence of GEN_HDRS that is
too similarly named would confuse developers who are adding new
generated header files which list to add theirs.
- Even though unicode-width.h could be generated using a contrib/
script, as far as our build infrastructure is concerned, it is a
source file that is tracked in the source control system. Its
presence in GEN_HDRS list is doubly misleading.
Get rid of GEN_HDRS, which is used only once to list the headers we
do not run hdr-check test on, and instead explicitly list that the
ones, either tracked or generated, that we exempt from the test.
This allows GENERATED_H to be the sole "here are build artifact
header files that are expendable" list, so use it in the clean
target to $(RM) them.

In the previous steps, we re-implemented the main loop of `git add -i`
in C, and most of the commands.
Notably, we left out the actual functionality of `patch`, as the
relevant code makes up more than half of `git-add--interactive.perl`,
and is actually pretty independent of the rest of the commands.
With this commit, we start to tackle that `patch` part. For better
separation of concerns, we keep the code in a separate file,
`add-patch.c`. The new code is still guarded behind the
`add.interactive.useBuiltin` config setting, and for the moment,
it can only be called via `git add -p`.
The actual functionality follows the original implementation of
5cde71d64aff (git-add --interactive, 2006-12-10), but not too closely
(for example, we use string offsets rather than copying strings around,
and after seeing whether the `k` and `j` commands are applicable, in the
C version we remember which previous/next hunk was undecided, and use it
rather than looking again when the user asked to jump).
As a further deviation from that commit, We also use a comma instead of
a slash to separate the available commands in the prompt, as the current
version of the Perl script does this, and we also add a line about the
question mark ("print help") to the help text.
While it is tempting to use this conversion of `git add -p` as an excuse
to work on `apply_all_patches()` so that it does _not_ want to read a
file from `stdin` or from a file, but accepts, say, an `strbuf` instead,
we will refrain from this particular rabbit hole at this stage.

The sparse-checkout feature is mostly hidden to users, as its
only documentation is supplementary information in the docs for
'git read-tree'. In addition, users need to know how to edit the
.git/info/sparse-checkout file with the right patterns, then run
the appropriate 'git read-tree -mu HEAD' command. Keeping the
working directory in sync with the sparse-checkout file requires
care.
Begin an effort to make the sparse-checkout feature a porcelain
feature by creating a new 'git sparse-checkout' builtin. This
builtin will be the preferred mechanism for manipulating the
sparse-checkout file and syncing the working directory.
The documentation provided is adapted from the "git read-tree"
documentation with a few edits for clarity in the new context.
Extra sections are added to hint toward a future change to
a more restricted pattern set.

Unlike previous conversions to C, where we started with a built-in
helper, we start this conversion by adding an interception in the
`run_add_interactive()` function when the new opt-in
`add.interactive.useBuiltin` config knob is turned on (or the
corresponding environment variable `GIT_TEST_ADD_I_USE_BUILTIN`), and
calling the new internal API function `run_add_i()` that is implemented
directly in libgit.a.
At this point, the built-in version of `git add -i` only states that it
cannot do anything yet. In subsequent patches/patch series, the
`run_add_i()` function will gain more and more functionality, until it
is feature complete. The whole arc of the conversion can be found in the
PRs #170-175 at https://github.com/gitgitgadget/git.
The "--helper approach" can unfortunately not be used here: on Windows
we face the very specific problem that a `system()` call in
Perl seems to close `stdin` in the parent process when the spawned
process consumes even one character from `stdin`. Which prevents us from
implementing the main loop in C and still trying to hand off to the Perl
script.
The very real downside of the approach we have to take here is that the
test suite won't pass with `GIT_TEST_ADD_I_USE_BUILTIN=true` until the
conversion is complete (the `--helper` approach would have let it pass,
even at each of the incremental conversion steps).

The 'git commit-graph read' subcommand is used in test scripts to check
that the commit-graph contents match the expected data. Mostly, this
helps check the header information and the list of chunks. Users do not
need this information, so move the functionality to a test helper.

When the %.cocci.patch target was defined in 63f0a758a0 (add coccicheck
make target, 2016-09-15), it included a mechanism to suppress the noisy
output, similar to the $(QUIET_<x>) family of variables.
In the case where one wants to inspect the output hidden by
$(QUIET_<x>), one could define $(V) for verbose output. In the
%.cocci.patch target, this was not implemented.
Move the output suppression into the $(QUIET_SPATCH) variable which is
used like the other $(QUIET_<x>) variables. While we're at it, change
the number of spaces printed from 5 to 4, like the other variables
there.

by similarity to pick the best candidate, which means that a tie
between sources with the same similarity is broken by the original
