Junio C Hamano 640f9cd599 Merge branch 'dl/rebase-i-keep-base'
"git rebase --keep-base <upstream>" tries to find the original base
of the topic being rebased and rebase on top of that same base,
which is useful when running the "git rebase -i" (and its limited
variant "git rebase -x").

The command also has learned to fast-forward in more cases where it
can instead of replaying to recreate identical commits.

Alexandr Miloslavskiy fe0ed5d5e9 contrib/buildsystems: fix Visual Studio Debug configuration
Even though Debug configuration builds, the resulting build is incorrect
in a subtle way: it mixes up Debug and Release binaries, which in turn
causes hard-to-predict bugs.

In my case, when git calls iconv library, iconv sets 'errno' and git
then tests it, but in Debug and Release CRT those 'errno' are different
memory locations.

This patch addresses 3 connected bugs:
1) Typo in '\(Configuration)'. As a result, Debug configuration
   condition is always false and Release path is taken instead.
2) Regexp that replaced 'zlib.lib' with 'zlibd.lib' was only affecting
   the first occurrence. However, some projects have it listed twice.
   Previously this bug was hidden, because Debug path was never taken.
   I decided that avoiding double -lz in makefile is fragile and I'd
   better replace all occurrences instead.
3) In Debug, 'libcurl-d.lib' should be used instead of 'libcurl.lib'.
   Previously this bug was hidden, because Debug path was never taken.

Denton Liu aeeb978ba6 completion: teach archive to use __gitcomp_builtin
Currently, _git_archive() uses a hardcoded list of options for its
completion. However, we can use __gitcomp_builtin() to get a dynamically
generated list of completions instead.

Teach _git_archive() to use __gitcomp_builtin() so that newly
implemented options in archive will be automatically completed without
any mucking around in git-completion.bash. While we're at it, teach it
to complete the missing `--worktree-attributes` option as well.

Unfortunately, since some args are passed through from cmd_archive() to
write_archive() (which calls parse_archive_args()), there's no way that a
`--git-completion-helper` arg can end up reaching parse_archive_args()
since the first call to parse_options() will end up calling exit(0). As
a result, we have to carry the options supported by write_archive() in
the hardcoded string.

Elijah Newren 9df53c5de6 Recommend git-filter-repo instead of git-filter-branch
filter-branch suffers from a deluge of disguised dangers that disfigure
history rewrites (i.e. deviate from the deliberate changes).  Many of
these problems are unobtrusive and can easily go undiscovered until the
new repository is in use.  This can result in problems ranging from an
even messier history than what led folks to filter-branch in the first
place, to data loss or corruption.  These issues cannot be backward
compatibly fixed, so add a warning to both filter-branch and its manpage
recommending that another tool (such as filter-repo) be used instead.

Also, update other manpages that referenced filter-branch.  Several of
these needed updates even if we could continue recommending
filter-branch, either due to implying that something was unique to
filter-branch when it applied more generally to all history rewriting
tools (e.g. BFG, reposurgeon, fast-import, filter-repo), or because
something about filter-branch was used as an example despite other more
commonly known examples now existing.  Reword these sections to fix
these issues and to avoid recommending filter-branch.

Finally, remove the section explaining BFG Repo Cleaner as an
alternative to filter-branch.  I feel somewhat bad about this,
especially since I feel like I learned so much from BFG that I put to
good use in filter-repo (which is much more than I can say for
filter-branch), but keeping that section presented a few problems:
  * In order to recommend that people quit using filter-branch, we need
    to provide them a recomendation for something else to use that
    can handle all the same types of rewrites.  To my knowledge,
    filter-repo is the only such tool.  So it needs to be mentioned.
  * I don't want to give conflicting recommendations to users
  * If we recommend two tools, we shouldn't expect users to learn both
    and pick which one to use; we should explain which problems one
    can solve that the other can't or when one is much faster than
    the other.
  * BFG and filter-repo have similar performance
  * All filtering types that BFG can do, filter-repo can also do.  In
    fact, filter-repo comes with a reimplementation of BFG named
    bfg-ish which provides the same user-interface as BFG but with
    several bugfixes and new features that are hard to implement in
    BFG due to its technical underpinnings.
While I could still mention both tools, it seems like I would need to
provide some kind of comparison and I would ultimately just say that
filter-repo can do everything BFG can, so ultimately it seems that it
is just better to remove that section altogether.

Denton Liu 414d924beb rebase: teach rebase --keep-base
A common scenario is if a user is working on a topic branch and they
wish to make some changes to intermediate commits or autosquash, they
would run something such as

	git rebase -i --onto master... master

in order to preserve the merge base. This is useful when contributing a
patch series to the Git mailing list, one often starts on top of the
current 'master'. While developing the patches, 'master' is also
developed further and it is sometimes not the best idea to keep rebasing
on top of 'master', but to keep the base commit as-is.

In addition to this, a user wishing to test individual commits in a
topic branch without changing anything may run

	git rebase -x ./test.sh master... master

Since rebasing onto the merge base of the branch and the upstream is
such a common case, introduce the --keep-base option as a shortcut.

This allows us to rewrite the above as

	git rebase -i --keep-base master

and

	git rebase -x ./test.sh --keep-base master

respectively.

Add tests to ensure --keep-base works correctly in the normal case and
fails when there are multiple merge bases, both in regular and
interactive mode. Also, test to make sure conflicting options cause
rebase to fail. While we're adding test cases, add a missing
set_fake_editor call to 'rebase -i --onto master...side'.

While we're documenting the --keep-base option, change an instance of
"merge-base" to "merge base", which is the consistent spelling.

SZEDER Gábor 5af9d5f6c8 completion: complete config variables and values for 'git clone --config='
Completing configuration sections and variable names for the stuck
argument of 'git clone --config=<TAB>' requires a bit of extra care
compared to doing the same for the unstuck argument of 'git clone
--config <TAB>', because we have to deal with that '--config=' being
part of the current word to be completed.

Add an option to the __git_complete_config_variable_name_and_value()
and in turn to the __git_complete_config_variable_name() helper
functions to specify the current section/variable name to be
completed, so they can be used even when completing the stuck argument
of '--config='.

__git_complete_config_variable_value() already has such an option, and
thus no further changes were necessary to complete possible values
after 'git clone --config=section.name=<TAB>'.

configuration section, variable names, and their valus after 'git -c
<TAB>', and with a bit of foresight encapsulated all that in a
dedicated helper function.  Use that function to complete the unstuck
argument of 'git config -c|--config <TAB>', which expect configuration
variables and values in the same 'section.name=value' form.

Note that handling the struck argument for 'git clone --config=<TAB>'
requires some extra care, so it will be done a separate patch.

Add new options to the __git_complete_config_variable_value() function

configuration variable whose value is to be completed, and use these

SZEDER Gábor e1e00089da completion: complete configuration sections and variable names for 'git -c'
'git config' expects a configuration variable's name and value in
separate arguments, so we let the __gitcomp() helper append a space
character to each variable name by default, like we do for most other
things (--options, refs, paths, etc.).  'git -c', however, expects
them in a single option joined by a '=' character, i.e.
'section.name=value', so we should append a '=' character to each
fully completed variable name, but no space, so the user can continue
typing the value right away.

Add an option to the __git_complete_config_variable_name() function to
allow callers to specify an alternate suffix to add, and use it to
append that '=' character to configuration variables.  Update the
__gitcomp() helper function to not append a trailing space to any
completion words ending with a '=', not just to those option with a
stuck argument.

SZEDER Gábor d9ee1e0617 completion: simplify inner 'case' pattern in __gitcomp()
The second '*' in the '--*=*' pattern of the inner 'case' statement of
the __gitcomp() helper function never matches anything, so let's use
'--*=' instead.

The purpose of that inner case statement is to decide when to append a
trailing space to the listed options and when not.  When an option
requires a stuck argument, i.e. '--option=', then the trailing space
should not be added, so the user can continue typing the required
argument right away.  That '--*=*' pattern is supposed to match these
options, but for this purpose that second '*' is unnecessary, a '--*='
pattern works just as well.  That second '*' would only make a
difference in case of a possible completion word like
'--option=value', but our completion script never passes such a word
to __gitcomp(), because the '--option=' and its 'value' must be
completed separately.

SZEDER Gábor d9438873c4 completion: deduplicate configuration sections
The number of configuration variables listed by the completion script
grew quite when we started to auto-generate it from the documentation
[1], so we now complete them in two steps: first we list only the
section names, then the rest [2].  To get the section names we simply
strip everything following the first dot in each variable name,
resulting in a lot of repeated section names, because most sections
contain more than one configuration variable.  This is not a
correctness issue in practice, because Bash's completion facilities
remove all repetitions anyway, but these repetitions make testing a
bit harder.

Replace the small 'sed' script removing subsections and variable names
with an 'awk' script that does the same, and in addition removes any
repeated configuration sections as well (by first creating and filling
an associative array indexed by all encountered configuration
sections, and then iterating over this array and printing the indices,
i.e. the unique section names).  This change makes the failing 'git
config - section' test in 't9902-completion.sh' pass.

Note that this changes the order of section names in the output, and
makes it downright undeterministic, but this is not an issue, because
Bash sorts them before presenting them to the user, and our completion
tests sort them as well before comparing with the expected output.

Yeah, it would be simpler and shorter to just append '| sort -u' to
that command, but that would incur the overhead of one more external
process and pipeline stage every time a user completes configuration
sections.

SZEDER Gábor 840d7e5b3c completion: complete more values of more 'color.*' configuration variables
Most 'color.*' configuration variables, with the sole exception of
'color.pager', accept the same set of values, but our completion
script recognizes only about half of them.  We could explicitly add
all those missing variables, but let's try to reduce future
maintenance burden, and use the catch-all 'color.*' pattern instead,
so this list won't get out of sync when a similar new configuration
variable accepting the same values is introduced [1].

Furthermore, their documentation explicitly mentions that they all
accept the standard boolean values 'false' and 'true' as well, so list
these, too, among the possible values.

[1] OTOH, there will be a maintenance burden if ever a new
    'color.something' is introduced which doesn't accept the same set
    of values.  We'll see which one happens first...

Johannes Schindelin b18ae14a8f vcxproj: also link-or-copy builtins
The default location for `.exe` files linked by Visual Studio depends on
the mode (debug vs release) and the architecture. Meaning: after a full
build, there is a `git.exe` in the top-level directory, but none of the
built-ins are linked..

When running a test script in Git Bash, it therefore would pick up the
wrong, say, `git-receive-pack.exe`: the one installed at the same time
as the Git Bash.

Absolutely not what we want. We want to have confidence that our test
covers the MSVC-built Git executables, and not some random stuff.

Johannes Schindelin 976aaedca0 msvc: add a Makefile target to pre-generate the Visual Studio solution
The entire idea of generating the VS solution makes only sense if we
generate it via Continuous Integration; otherwise potential users would
still have to download the entire Git for Windows SDK.

If we pre-generate the Visual Studio solution, Git can be built entirely
within Visual Studio, and the test scripts can be run in a regular Git
for Windows (e.g. the Portable Git flavor, which does not include a full
GCC toolchain and therefore weighs only about a tenth of Git for
Windows' SDK).

So let's just add a target in the Makefile that can be used to generate
said solution; The generated files will then be committed so that they
can be pushed to a branch ready to check out by Visual Studio users.

To make things even more useful, we also generate and commit other files
that are required to run the test suite, such as templates and
bin-wrappers: with this, developers can run the test suite in a regular
Git Bash after building the solution in Visual Studio.

Note: for this build target, we do not actually need to initialize the
`vcpkg` system, so we don't.

Johannes Schindelin 384a61bc6a contrib/buildsystems: add a backend for modern Visual Studio versions
Based on the previous patches in this patch series that fixed the
generator for `.vcproj` files (which were used by Visual Studio prior to
2015 to define projects), this patch offers to generate project
definitions for neweer versions of Visual Studio (which use `.vcxproj`
files).

To that end, this patch copy-edits the generator of the `.vcproj`.

In addition, we now use the `vcpkg` system which allows us to build
Git's dependencies (e.g. curl, libexpat) conveniently. The support
scripts were introduced in the `jh/msvc` patch series, and with this
patch we initialize the `vcpkg` conditionally, in the `libgit` project's
`PreBuildEvent`. To allow for parallel building of the projects, we
therefore put `libgit` at the bottom of the project hierarchy.

Git's test suite shows tons of breakages unless Git is compiled
*without* NO_ICONV. That means, in turn, that we need to generate
build definitions *with* libiconv, which in turn implies that we
have to handle the -liconv option properly.

Philip Oakley 03aa7118c3 contrib/buildsystems: redirect errors of the dry run into a log file
Rather than swallowing the errors, it is better to have them in a file.

To make it obvious what this is about, use the file name
'msvc-build-makedryerrors.txt'.

Further, if the output is empty, simply delete that file. As we target
Git for Windows' SDK (which, unlike its predecessor msysGit, offers Perl
versions newer than 5.8), we can use the quite readable syntax `if -f -z
$ErrsFile` (available in Perl >=5.10).

Note that the file will contain the new values of the GIT_VERSION and
GITGUI_VERSION if they were generated by the make file. They are omitted
if the release is tagged and indentically defined in their respective
GIT_VERSION_GEN file DEF_VER variables.

René Scharfe 177fbab747 coccinelle: use COPY_ARRAY for copying arrays
The current semantic patch for COPY_ARRAY transforms memcpy(3) calls on
pointers, but Coccinelle distinguishes them from arrays.  It already
contains three rules to handle the options for sizeof (i.e. source,
destination and type), and handling arrays as source and destination
would require four times as many rules if we enumerated all cases.

We also don't handle array subscripts, and supporting that would
increase the number of rules by another factor of four.  (An isomorphism
telling Coccinelle that "sizeof x[...]" is equivalent to "sizeof *x"
would be nice..)

Support arrays and array subscripts, but keep the number of rules down
by adding normalization steps: First turn array subscripts into
derefences, then determine the types of expressions used with sizeof and
replace them with these types, and then convert the different possible
combinations of arrays and pointers with memcpy(3) to COPY_ARRAY.

Nguyễn Thái Ngọc Duy 69702523af completion: do not cache if --git-completion-helper fails
"git <cmd> --git-completion-helper" could fail if the command checks for
a repo before parse_options(). If the result is cached, later on when
the user moves to a worktree with repo, tab completion will still fail.

Avoid this by detecting errors and not cache the completion output. We
can try again and hopefully succeed next time (e.g. when a repo is
found).

Of course if --git-completion-helper fails permanently because of other
reasons (*), this will slow down completion. But I don't see any better
option to handle that case.

(*) one of those cases is if __gitcomp_builtin is called on a command
  that does not support --git-completion-helper. And we do have a
  generic call

    __git_complete_common "$command"

  but this case is protected with __git_support_parseopt_helper so we're
  good.

Christian Couder e693237e2b list-objects-filter: disable 'sparse:path' filters
If someone wants to use as a filter a sparse file that is in the
repository, something like "--filter=sparse:oid=<ref>:<path>"
already works.

So 'sparse:path' is only interesting if the sparse file is not in
the repository. In this case though the current implementation has
a big security issue, as it makes it possible to ask the server to
read any file, like for example /etc/password, and to explore the
filesystem, as well as individual lines of files.

If someone is interested in using a sparse file that is not in the
repository as a filter, then at the minimum a config option, such
as "uploadpack.sparsePathFilter", should be implemented first to
restrict the directory from which the files specified by
'sparse:path' can be read.

For now though, let's just disable 'sparse:path' filters.

Any access to "maybe_tree" field directly will result in _broken_ code
after running through commit.cocci because we can't know what is the
right repository to use.

the_repository would be correct most of the time. But we're relying less

true. The transformation now is more of a poor man replacement for a C++

Nguyễn Thái Ngọc Duy a133c40b23 commit.cocci: refactor code, avoid double rewrite
"maybe" pointer in 'struct commit' is tricky because it can be lazily
initialized to take advantage of commit-graph if available. This makes
it not safe to access directly.

This leads to a rule in commit.cocci to rewrite 'x->maybe_tree' to
'get_commit_tree(x)'. But that rule alone could lead to incorrectly
rewrite assignments, e.g. from

    x->maybe_tree = yes

to

    get_commit_tree(x) = yes

Because of this we have a second rule to revert this effect. Szeder
found out that we could do better by performing the assignment rewrite
rule first, then the remaining is read-only access and handled by the
current first rule.

For this to work, we need to transform "x->maybe_tree = y" to something
that does NOT contain "x->maybe_tree" to avoid the original first
rule. This is where set_commit_tree() comes in.

SZEDER Gábor 28c23cd4c3 strbuf.cocci: suggest strbuf_addbuf() to add one strbuf to an other
The best way to add one strbuf to an other is via:

  strbuf_addbuf(&sb, &sb2);

This is a bit more idiomatic and efficient than:

  strbuf_addstr(&sb, sb2.buf);

because the size of the second strbuf is known and thus it can spare a
strlen() call, and much more so than:

  strbuf_addf(&sb, "%s", sb2.buf);

because it can spare the whole vsnprintf() formatting magic.

Add new semantic patches to 'contrib/coccinelle/strbuf.cocci' to catch
these undesired patterns and to suggest strbuf_addbuf() instead.

Luckily, our codebase is already clean from any such undesired
patterns (but one of the in-flight topics just tried to sneak in such
a strbuf_addf() call).

brian m. carlson 974e4a85e3 cache: make oidcpy always copy GIT_MAX_RAWSZ bytes
There are some situations in which we want to store an object ID into
struct object_id without the_hash_algo necessarily being set correctly.
One such case is when cloning a repository, where we must read refs from
the remote side without having a repository from which to read the
preferred algorithm.

In this cases, we may have the_hash_algo set to SHA-1, which is the
default, but read refs into struct object_id that are SHA-256. When
copying these values, we will want to copy them completely, not just the
first 20 bytes. Consequently, make sure that oidcpy copies the maximum
number of bytes at all times, regardless of the setting of
the_hash_algo.

Since oidcpy and hashcpy are no longer functionally identical, remove
the Cocinelle object_id transformations that convert from one into the
other.

Chayoung You 6d54f528c7 completion: treat results of git ls-tree as file paths
Let's say there are files named 'foo bar.txt', and 'abc def/test.txt' in
repository. When following commands trigger a completion:

    git show HEAD:fo<Tab>
    git show HEAD:ab<Tab>

The completion results in bash/zsh:

    git show HEAD:foo bar.txt
    git show HEAD:abc def/

Where the both of them have an unescaped space in paths, so they'll be
misread by git. All entries of git ls-tree either a filename or a
directory, so __gitcomp_file() is proper rather than __gitcomp_nl().

Note the commit f12785a3, which handles quoted paths properly. Like this
case, we should dequote $cur_ for ?*:* case. For example, let's say
there is untracked directory 'abc deg', then trigger a completion:

    git show HEAD:abc\ de<Tab>
    git show HEAD:'abc de<Tab>
    git show HEAD:"abc de<Tab>

should uniquely complete 'abc def', but bash completes 'abc def' and
'abc deg' instead. In zsh, triggering a completion:

    git show HEAD:abc\ def/<Tab>

should complete 'test.txt', but nothing comes. The both problems will be
resolved by dequoting paths.

__git_complete_revlist_file() passes arguments to __gitcomp_nl() where
the first one is a list something like:

    abc def/Z
    foo bar.txt Z

where Z is the mark of the EOL.

- The trailing space of blob in __git ls-tree | sed.
  It makes the completion results become:

      git show HEAD:foo\ bar.txt\ <CURSOR>

  So git will try to find a file named 'foo bar.txt ' instead.

- The trailing slash of tree in __git ls-tree | sed.
  It makes the completion results on zsh become:

      git show HEAD:abc\ def/ <CURSOR>

  So that the last space on command like should be removed on zsh to
  complete filenames under 'abc def/'.

Chayoung You 7a478b36aa zsh: complete unquoted paths with spaces correctly
The following is the description of -Q flag of zsh compadd [1]:

    This flag instructs the completion code not to quote any
    metacharacters in the words when inserting them into the command
    line.

Let's say there is a file named 'foo bar.txt' in repository, but it's
not yet added to the repository. Then the following command triggers a
completion:

    git add fo<Tab>
    git add 'fo<Tab>
    git add "fo<Tab>

The completion results in bash:

    git add foo\ bar.txt
    git add 'foo bar.txt'
    git add "foo bar.txt"

While them in zsh:

    git add foo bar.txt
    git add 'foo bar.txt'
    git add "foo bar.txt"

The first one, where the pathname is not enclosed in quotes, should
escape the space with a backslash, just like bash completion does.
Otherwise, this leads git to think there are two files; foo, and
bar.txt.

The main cause of this behavior is __gitcomp_file_direct(). The both
implementions of bash and zsh are called with an argument 'foo bar.txt',
but only bash adds a backslash before a space on command line.

Stefan Beller afd69dcc21 object-store: prepare read_object_file to deal with any repo
As read_object_file is a widely used function (which is also regularly used
in new code in flight between master..pu), changing its signature is painful
is hard, as other series in flight rely on the original signature. It would
burden the maintainer if we'd just change the signature.

Introduce repo_read_object_file which takes the repository argument, and
hide the original read_object_file as a macro behind
NO_THE_REPOSITORY_COMPATIBILITY_MACROS, similar to
e675765235 (diff.c: remove implicit dependency on the_index, 2018-09-21)

SZEDER Gábor dd5d052c39 coccicheck: introduce 'pending' semantic patches
Teach `make coccicheck` to avoid patches named "*.pending.cocci" and
handle them separately in a new `make coccicheck-pending` instead.
This means that we can separate "critical" patches from "FYI" patches.
The former target can continue causing Travis to fail its static
analysis job, while the latter can let us keep an eye on ongoing
(pending) transitions without them causing too much fallout.

Document the intended use-cases around these two targets.
As the process around the pending patches is not yet fully explored,
leave that out.

Duy Nguyen 13374987dd completion: use __gitcomp_builtin for format-patch
This helps format-patch gain completion for a couple new options,
notably --range-diff.

Since send-email completion relies on $__git_format_patch_options
which is now reduced, we need to do something not to regress
send-email completion.

The workaround here is implement --git-completion-helper in
send-email.perl just as a bridge to "format-patch --git-completion-helper".
This is enough to use __gitcomp_builtin on send-email (to take
advantage of caching).

In the end, send-email.perl can probably reuse the same info it passes
to GetOptions() to generate full --git-completion-helper output so
that we don't need to keep track of its options in git-completion.bash
anymore. But that's something for another boring day.
