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.

af78249463 contrib/svn-fe: fix shebang for svnrdump_sim.py
The shebang for a python script should be "/usr/bin/env python" and not
"/usr/bin/python". On some OSes like AIX, python default path is not under
"/usr/bin" ("/opt/freeware/bin" for AIX).

Note the main reason behind this change is that AIX rpm will add a
dependency on "/usr/bin/python" instead of "/usr/bin/env".

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.

The bash completion script knows some options to "git log" and
"git show" only in the positive form, (e.g. "--abbrev-commit"), but not
in their negative form (e.g. "--no-abbrev-commit"). Add them.

Also, the bash completion script is missing some other options to

"git diff"'s options). Add them. Of note, since "--indent-heuristic" is
no longer experimental, add that too.

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.

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.

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>'.

88cd790d6a completion: complete config variables names and values for 'git clone -c'
The previous commits taught the completion script how to complete
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.

dd33472831 completion: complete values of configuration variables after 'git -c var='
'git config' expects a configuration variable's name and value in
separate options, so we complete values as they stand on their own on
the command line.  'git -c', however, expects them in a single option
joined by a '=' character, so we should be able to complete values
when they are following 'section.name=' in the same word.

Add new options to the __git_complete_config_variable_value() function
to allow callers to specify the current word to be completed and the
configuration variable whose value is to be completed, and use these
to complete possible values after 'git -c 'section.name=<TAB>'.

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.

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.

2675ea1cc0 completion: use 'sort -u' to deduplicate config variable names
The completion script runs the classic '| sort | uniq' pipeline to
deduplicate the output of 'git help --config-for-completion'.  'sort

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.

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...

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.

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.

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.

4553f9de23 contrib/buildsystems: handle options starting with a slash
With the recent changes to allow building with MSVC=1, we now pass the
/OPT:REF option to the compiler. This confuses the parser that wants to
turn the output of a dry run into project definitions for QMake and Visual
Studio:

	Unhandled link option @ line 213: /OPT:REF at [...]

Let's just extend the code that passes through options that start with a
dash, so that it passes through options that start with a slash, too.

1a537ecfbb contrib/buildsystems: handle libiconv, too
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.

66697467f8 contrib/buildsystems: error out on unknown option
One time too many did this developer call the `generate` script passing
a `--make-out=<PATH>` option that was happily ignored (because there
should be a space, not an equal sign, between `--make-out` and the
path).

And one time too many, this script not only ignored it but did not even
complain. Let's fix that.

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.

865406bc54 contrib/buildsystems: ignore invalidcontinue.obj
Since 4b623d8 (MSVC: link in invalidcontinue.obj for better POSIX
compatibility, 2014-03-29), invalidcontinue.obj is linked in the MSVC
build, but it was not parsed correctly by the buildsystem. Ignore it, as
it is known to Visual Studio and will be handled elsewhere.

Also only substitute filenames ending with .o when generating the
source .c filename, otherwise we would start to expect .cbj files to
generate .obj files (which are not generated by our build)...

In the future there may be source files that produce .obj files
so keep the two issues (.obj files with & without source files)
separate.

92e2f6e053 Vcproj.pm: list git.exe first to be startup project
Visual Studio takes the first listed application/library as the default
startup project [1].

Detect the 'git' project and place it at the head of the project list,
rather than at the tail.

Export the apps list before libs list for both the projects and global
structures of the .sln file.

    "just moving the pseudo-xml isn't enough. You also have to move the

We ran out GUIDs. Again. But there is no need to: we can generate them
semi-randomly from the target file name of the project.

Note: the Vcproj generator is probably only interesting for historical
reasons; nevertheless, the upcoming Vcxproj generator (to support modern
Visual Studio versions) is based on the Vcproj generator and it is
better to fix this here first.
