Mark prompt message assembled in place for translation, unfolding each
use case for each entry in the %patch_modes hash table.
Previously, this script relied on whether $patch_mode was set to run the
command patch_update_cmd() or show status and loop the main loop. Now,
it uses $cmd to indicate we must run patch_update_cmd() and $patch_mode
is used to tell which flavor of the %patch_modes are we on. This is
introduced in order to be able to mark and unfold the message prompt
knowing in which context we are.
The tracking of context was done previously by point %patch_mode_flavour
hash table to the correct entry of %patch_modes, focusing only on value
of %patch_modes. Now, we are also interested in the key ('staged',
'stash', 'checkout_head', ...).

When you're working on the git project, you're unlikely to
care about random bits in contrib/ (e.g., you would not want
to jump to the copy of xmalloc in the wincred credential
helper). Nobody has really complained because there are
relatively few C files in contrib.
Now that we're matching shell scripts, too, we get quite a
few more hits, especially in the obsolete contrib/examples
directory. Looking for usage() should turn up the one in
git-sh-setup, not in some long-dead version of git-clone.
Let's just exclude all of contrib. Any specific projects
there which are big enough to want tags can generate them
separately.

We feed FIND_SOURCE_FILES to ctags to help developers
navigate to particular functions, but we only feed C source
code. The same feature can be helpful when working with
shell scripts (especially the test suite). Modern versions
of ctags know how to parse shell scripts; we just need to
feed the filenames to it.
This patch specifically avoids including the individual test
scripts themselves. Those are unlikely to be of interest,
and there are a lot of them to process. It does pick up
test-lib.sh and test-lib-functions.sh.
Note that our negative pathspec already excludes the
individual scripts for the ls-files case, but we need to
loosen the `find` rule to match it.

The test directory may contain three types of files that
match our patterns:
1. Helper programs in t/helper.
2. Sample data files (e.g., t/t4051/hello.c).
3. Untracked cruft in trash directories and t/perf/build.
We want to match (1), but not the other two, as they just
clutter up the list.
For the ls-files method, we can drop (2) with a negative
pathspec. We do not have to care about (3), since ls-files
will not list untracked files.
For `find`, we can match both cases with `-prune` patterns.

The xdiff code hashes every line of both sides of a diff,
and then compares those hashes to find duplicates. The
overall performance depends both on how fast we can compute
the hashes, but also on how many hash collisions we see.
The idea of XDL_FAST_HASH is to speed up the hash
computation. But the generated hashes have worse collision
behavior. This means that in some cases it speeds diffs up
(running "git log -p" on git.git improves by ~8% with it),
but in others it can slow things down. One pathological case
saw over a 100x slowdown[1].
There may be a better hash function that covers both
properties, but in the meantime we are better off with the
original hash. It's slightly slower in the common case, but
it has fewer surprising pathological cases.

In order for the receiving end of "git push" to inspect the
received history and decide to reject the push, the objects sent
from the sending end need to be made available to the hook and
the mechanism for the connectivity check, and this was done
traditionally by storing the objects in the receiving repository
and letting "git gc" to expire it. Instead, store the newly
received objects in a temporary area, and make them available by
reusing the alternate object store mechanism to them only while we
decide if we accept the check, and once we decide, either migrate
them to the repository or purge them immediately.
* jk/quarantine-received-objects:
tmp-objdir: do not migrate files starting with '.'
tmp-objdir: put quarantine information in the environment
receive-pack: quarantine objects until pre-receive accepts
tmp-objdir: introduce API for temporary object directories
check_connected: accept an env argument
|
|
Once objects are added to the object database by a process,
they cannot easily be deleted, as we don't know what other
processes may have started referencing them. We have to
clean them up with git-gc, which will apply the usual
reachability and grace-period checks.
This patch provides an alternative: it helps callers create
a temporary directory inside the object directory, and a
temporary environment which can be passed to sub-programs to
ask them to write there (the original object directory
remains accessible as an alternate of the temporary one).
See tmp-objdir.h for details on the API.

Some codepaths in "git diff" used regexec(3) on a buffer that was
mmap(2)ed, which may not have a terminating NUL, leading to a read
beyond the end of the mapped region. This was fixed by introducing
a regexec_buf() helper that takes a <ptr,len> pair with REG_STARTEND
extension.
* js/regexec-buf:
regex: use regexec_buf()
regex: add regexec_buf() that can work on a non NUL-terminated string
regex: -G<pattern> feeds a non NUL-terminated string to regexec() and fails

Code cleanup.
* rs/cocci:
use strbuf_addstr() for adding constant strings to a strbuf, part 2
add coccicheck make target
contrib/coccinelle: fix semantic patch for oid_to_hex_r()
|
|
We just introduced a test that demonstrates that our sloppy use of
regexec() on a mmap()ed area can result in incorrect results or even
hard crashes.
So what we need to fix this is a function that calls regexec() on a
length-delimited, rather than a NUL-terminated, string.
Happily, there is an extension to regexec() introduced by the NetBSD
project and present in all major regex implementation including
Linux', MacOSX' and the one Git includes in compat/regex/: by using
the (non-POSIX) REG_STARTEND flag, it is possible to tell the
regexec() function that it should only look at the offsets between
pmatch[0].rm_so and pmatch[0].rm_eo.
That is exactly what we need.
Since support for REG_STARTEND is so widespread by now, let's just
introduce a helper function that always uses it, and tell people
on a platform whose regex library does not support it to use the
one from our compat/regex/ directory.

Provide a simple way to run Coccinelle against all source files, in the
form of a Makefile target. Running "make coccicheck" applies each
.cocci file in contrib/coccinelle/ on all source files. It generates
a .patch file for each .cocci file, containing the actual changes for
effecting the transformations described by the semantic patches.
Non-empty .patch files are reported. They can be applied to the work
tree using "patch -p0", but should be checked to e.g. make sure they
don't screw up formatting or create circular references.
Coccinelle's diagnostic output (stderr) is piped into .log files.

Move our implementation of strdup(3) out of compat/nedmalloc/ and
allow it to be used independently from USE_NED_ALLOCATOR. The
original nedmalloc doesn't come with strdup() and doesn't need it.
Only _users_ of nedmalloc need it, which was added when we imported
it to our compat/ hierarchy.
This reduces the difference of our copy of nedmalloc from the
original, making it easier to update, and allows for easier testing
and reusing of our version of strdup().

There are a few places in Git that would benefit from a fast
most-recently-used cache (e.g., the list of packs, which we
search linearly but would like to order based on locality).
This patch introduces a generic list that can be used to
store arbitrary pointers in most-recently-used order.
The implementation is just a doubly-linked list, where
"marking" an item as used moves it to the front of the list.
Insertion and marking are O(1), and iteration is O(n).
There's no lookup support provided; if you need fast
lookups, you are better off with a different data structure
in the first place.
There is also no deletion support. This would not be hard to
do, but it's not necessary for handling pack structs, which
are created and never removed.

Makefile assumed that -lrt is always available on platforms that
want to use clock_gettime() and CLOCK_MONOTONIC, which is not a
case for recent Mac OS X. The necessary symbols are often found in
libc on many modern systems and having -lrt on the command line, as
long as the library exists, had no effect, but when the platform
removes librt.a that is a different matter--having -lrt will break
the linkage.

We unconditionally link with librt, when HAVE_CLOCK_GETTIME is defined.
But clock_gettime() has been available in most libc implementations for
some time now (e.g., for glibc since version 2.17) and no longer
requires linking with librt. Furthermore, commit a6c3c63 (configure.ac:
check for clock_gettime() and CLOCK_MONOTONIC) will automatically
determined which library (libc or librt) is required for linking when
checking for clock_gettime().
The assumption to unconditionally link with librt was OK, since either
almost every Unix-like system provides a version of librt for backwards
compatibility or other systems, namely Windows or OS X, never provided
clock_gettime(). However, in the latest release of OS X (macOS Sierra),
this function has been added to OS X libc version. As a result, when
running the configuration script, HAVE_CLOCK_GETTIME is set and since
librt is not present, it causes a linker error.
This patches requires those not building via the configuration scripts
to define NEEDS_LIBRT in addition to HAVE_CLOCK_GETTIME, if needed.

A few test-helpers have Makefile dependencies on specific
object files. But since these files are part of libgit.a
(which all of the helpers link against), the inclusion is
simply redundant.
These were once necessary, but became redundant due to
5c5ba73 (Makefile: Use generic rule to build test programs,
2007-05-31), which added the $(GITLIBS) dependency (but
didn't prune the extra dependency lines). Later commits then
cargo-culted the practice (e.g., b4285c7).
Note that we _do_ need to leave the dependencies on the svn
library, as that is not part of the usual link command.

There are certain startup tasks that we expect every git
process to do. In some cases this is just to improve the
quality of the program (e.g., setting up gettext()). In
others it is a requirement for using certain functions in
libgit.a (e.g., system_path() expects that you have called
git_extract_argv0_path()).
Most commands are builtins and are covered by the git.c
version of main(). However, there are still a few external
commands that use their own main(). Each of these has to
remember to include the correct startup sequence, and we are
not always consistent.
Rather than just fix the inconsistencies, let's make this
harder to get wrong by providing a common main() that can
run this standard startup.
We basically have two options to do this:
- the compat/mingw.h file already does something like this by
adding a #define that replaces the definition of main with a
wrapper that calls mingw_startup().
The upside is that the code in each program doesn't need
to be changed at all; it's rewritten on the fly by the
preprocessor.
The downside is that it may make debugging of the startup
sequence a bit more confusing, as the preprocessor is
quietly inserting new code.
- the builtin functions are all of the form cmd_foo(),
and git.c's main() calls them.
This is much more explicit, which may make things more
obvious to somebody reading the code. It's also more
flexible (because of course we have to figure out _which_
cmd_foo() to call).
The downside is that each of the builtins must define
cmd_foo(), instead of just main().
This patch chooses the latter option, preferring the more
explicit approach, even though it is more invasive. We
introduce a new file common-main.c, with the "real" main. It
expects to call cmd_main() from whatever other objects it is
linked against.
We link common-main.o against anything that links against
libgit.a, since we know that such programs will need to do
this setup. Note that common-main.o can't actually go inside
libgit.a, as the linker would not pick up its main()
function automatically (it has no callers).
The rest of the patch is just adjusting all of the various
external programs (mostly in t/helper) to use cmd_main().
I've provided a global declaration for cmd_main(), which
means that all of the programs also need to match its
signature. In particular, many functions need to switch to
"const char **" instead of "char **" for argv. This effect
ripples out to a few other variables and functions, as well.
This makes the patch even more invasive, but the end result
is much better. We should be treating argv strings as const
anyway, and now all programs conform to the same signature
(which also matches the way builtins are defined).

The iterator interface is modeled on that for references, though no
vtable is necessary because there is (so far?) only one type of
dir_iterator.
There are obviously a lot of features that could easily be added to this
class:
* Skip/include directory paths in the iteration
* Shallow/deep iteration
* Letting the caller decide which subdirectories to recurse into (e.g.,
via a dir_iterator_advance_into() function)
* Option to iterate in sorted order
* Option to iterate over directory paths before vs. after their contents
But these are not needed for the current patch series, so I refrain.

Currently, the API for iterating over references is via a family of
for_each_ref()-type functions that invoke a callback function for each
selected reference. All of these eventually call do_for_each_ref(),
which knows how to do one thing: iterate in parallel through two
ref_caches, one for loose and one for packed refs, giving loose
references precedence over packed refs. This is rather complicated code,
and is quite specialized to the files backend. It also requires callers
to encapsulate their work into a callback function, which often means
that they have to define and use a "cb_data" struct to manage their
context.
The current design is already bursting at the seams, and will become
even more awkward in the upcoming world of multiple reference storage
backends:
* Per-worktree vs. shared references are currently handled via a kludge
in git_path() rather than iterating over each part of the reference
namespace separately and merging the results. This kludge will cease
to work when we have multiple reference storage backends.
* The current scheme is inflexible. What if we sometimes want to bypass
the ref_cache, or use it only for packed or only for loose refs? What
if we want to store symbolic refs in one type of storage backend and
non-symbolic ones in another?
In the future, each reference backend will need to define its own way of
iterating over references. The crux of the problem with the current
design is that it is impossible to compose for_each_ref()-style
iterations, because the flow of control is owned by the for_each_ref()
function. There is nothing that a caller can do but iterate through all
references in a single burst, so there is no way for it to interleave
references from multiple backends and present the result to the rest of
the world as a single compound backend.
This commit introduces a new iteration primitive for references: a
ref_iterator. A ref_iterator is a polymorphic object that a reference
storage backend can be asked to instantiate. There are three functions
that can be applied to a ref_iterator:
* ref_iterator_advance(): move to the next reference in the iteration
* ref_iterator_abort(): end the iteration before it is exhausted
* ref_iterator_peel(): peel the reference currently being looked at
Iterating using a ref_iterator leaves the flow of control in the hands
of the caller, which means that ref_iterators from multiple
sources (e.g., loose and packed refs) can be composed and presented to
the world as a single compound ref_iterator.
It also means that the backend code for implementing reference iteration
will sometimes be more complicated. For example, the
cache_ref_iterator (which iterates over a ref_cache) can't use the C
stack to recurse; instead, it must manage its own stack internally as
explicit data structures. There is also a lot of boilerplate connected
with object-oriented programming in C.
Eventually, end-user callers will be able to be written in a more
natural way—managing their own flow of control rather than having to
work via callbacks. Since there will only be a few reference backends
but there are many consumers of this API, this is a good tradeoff.
More importantly, we gain composability, and especially the possibility
of writing interchangeable parts that can work with any ref_iterator.
For example, merge_ref_iterator implements a generic way of merging the
contents of any two ref_iterators. It is used to merge loose + packed
refs as part of the implementation of the files_ref_iterator. But it
will also be possible to use it to merge other pairs of reference
sources (e.g., per-worktree vs. shared refs).
Another example is prefix_ref_iterator, which can be used to trim a
prefix off the front of reference names before presenting them to the
caller (e.g., "refs/heads/master" -> "master").
In this patch, we introduce the iterator abstraction and many utilities,
and implement a reference iterator for the files ref storage backend.
(I've written several other obvious utilities, for example a generic way
to filter references being iterated over. These will probably be useful
in the future. But they are not needed for this patch series, so I am
not including them at this time.)
In a moment we will rewrite do_for_each_ref() to work via reference
iterators (allowing some special-purpose code to be discarded), and do
something similar for reflogs. In future patch series, we will expose
the ref_iterator abstraction in the public refs API so that callers can
use it directly.
Implementation note: I tried abstracting this a layer further to allow
generic iterators (over arbitrary types of objects) and generic
utilities like a generic merge_iterator. But the implementation in C was
very cumbersome, involving (in my opinion) too much boilerplate and too
much unsafe casting, some of which would have had to be done on the
caller side. However, I did put a few iterator-related constants in a
top-level header file, iterator.h, as they will be useful in a moment to
implement iteration over directory trees and possibly other types of
iterators in the future.

Mark strings in git-rebase--interactive.sh for translation. There is no
need to source git-sh-i18n since git-rebase.sh already does so.
Add git-rebase--interactive.sh to LOCALIZED_SH in Makefile in order to
enable extracting strings marked for translation by xgettext.

Positional arguments, such as $0, $1, etc, need to be stored on shell
variables for use in translatable strings, according to gettext manual
[1].
Add git-sh-setup.sh to LOCALIZED_SH variable in Makefile to enable
extraction of string marked for translation by xgettext.
Source git-sh-i18n in git-sh-setup.sh for gettext support.
git-sh-setup.sh is a shell library to be sourced by other shell scripts.
In order to avoid other scripts from sourcing git-sh-i18n twice, remove
line that sources it from them. Not sourcing git-sh-i18n in any script
that uses gettext would lead to failure due to, for instance, gettextln
not being found.

"make DEVELOPER=1" worked as expected; setting DEVELOPER=1 in
config.mak didn't.
* mm/makefile-developer-can-be-in-config-mak:
Makefile: add $(DEVELOPER_CFLAGS) variable
Makefile: move 'ifdef DEVELOPER' after config.mak* inclusion
|
|
This does not change the behavior, but allows the user to tweak
DEVELOPER_CFLAGS on the command-line or in a config.mak* file if
needed.
This also makes the code somewhat cleaner as it follows the pattern
<initialisation of variables>
<include statements>
<actual build logic>
by specifying which flags to activate in the first part, and actually
activating them in the last one.

The DEVELOPER knob was introduced in 658df95 (add DEVELOPER makefile
knob to check for acknowledged warnings, 2016-02-25), and works well
when used as "make DEVELOPER=1", and when the configure script was not
used.
However, the advice given in CodingGuidelines to add DEVELOPER=1 to
config.mak does not: config.mak is included after testing for
DEVELOPER in the Makefile, and at least GNU Make's manual specifies
"Conditional directives are parsed immediately", hence the config.mak
declaration is not visible at the time the conditional is evaluated.
Also, when using the configure script to generate a
config.mak.autogen, the later file contained a "CFLAGS = <flags>"
initialization, which overrode the "CFLAGS += -W..." triggered by
DEVELOPER.
This patch fixes both issues.

Find common mistakes when writing gitlink: in our documentation and
drive the check from "make check-docs".
I am not entirely happy with the way the script chooses what input
file to validate, but it is not worse than not having anything, so
let's move it forward and have the logic improved later when people
care about it deeply.

It is easy to add incorrect "linkgit:<page>[<section>]" references
to our documentation suite. Catch these common classes of errors:
* Referring to Documentation/<page>.txt that does not exist.
* Referring to a <page> outside the Git suite. In general, <page>
must begin with "git".
* Listing the manual <section> incorrectly. The first line of the
Documentation/<page>.txt must end with "(<section>)".
with a new script "ci/lint-gitlink", and drive it from "make check-docs".
