completion: handle path completion and colon for tcsh... Marc Khouzam Sat, 2 Feb 2013 19:43:25 +0000 (19:43 +0000)

completion: handle path completion and colon for tcsh script

Recent enhancements to git-completion.bash provide intelligent path
completion for git commands. Such completions do not provide the
'/' at the end of directories for recent versions of bash; instead,
bash itself will add the trailing slash to directories to the result
provided by git-completion.bash. However, the completion for tcsh
uses the result of the bash completion script directly, so it either
needs to add the necessary slash itself, or needs to ask the bash
script to keep the trailing slash.

Adding the slash itself is difficult because we have to check the
each path in the output of the bash script to see if it is meant to
be a directory or something else. For example, assuming there is a
directory named 'commit' in the current directory, then, when
completing

git add commit<tab>

we would need to add a slash, but for

git help commit<tab>

we should not.

Figuring out such differences would require adding much intelligence
to the tcsh completion script. Instead, it is simpler to ask the
bash script to keep the trailing slash. This patch does this.

Also, tcsh does not handle the colon as a completion separator so we
remove it from the list of separators.

Makefile: explicitly set target name for autogenerated... Jonathan Nieder Fri, 18 Nov 2011 23:23:24 +0000 (17:23 -0600)

Makefile: explicitly set target name for autogenerated dependencies

"gcc -MF depfile -MMD -MP -c -o path/to/file.o" produces a makefile
snippet named "depfile" describing what files are needed to build the
target given by "-o". When ccache versions before v3.0pre0~187 (Fix
handling of the -MD and -MDD options, 2009-11-01) run, they execute

gcc -MF depfile -MMD -MP -E

instead to get the final content for hashing. Notice that the "-c -o"
combination is replaced by "-E". The result is a target name without
a leading path.

Thus when building git with such versions of ccache with
COMPUTE_HEADER_DEPENDENCIES enabled, the generated makefile snippets
define dependencies for the wrong target:

$ make builtin/add.o
GIT_VERSION = 1.7.8.rc3
* new build flags or prefix
CC builtin/add.o
$ head -1 builtin/.depend/add.o.d
add.o: builtin/add.c cache.h git-compat-util.h compat/bswap.h strbuf.h \

After a change in a header file, object files in a subdirectory are
not automatically rebuilt by "make":

$ touch cache.h
$ make builtin/add.o
$

Luckily we can prevent trouble by explicitly supplying the name of the
target to ccache and gcc, using the -MQ option. Do so.

mergetools: teach tortoisemerge to handle filenames... Sven Strickroth Fri, 1 Feb 2013 20:16:30 +0000 (21:16 +0100)

mergetools: teach tortoisemerge to handle filenames with SP correctly

TortoiseGitMerge, unlike TortoiseMerge, can be told to handle paths
with spaces in them by using -option "$FILE" (not -option:"$FILE",
which does not work for such paths) syntax.

This change was necessary because of MSYS path mangling [1], the ":"
after the "base" etc. arguments to TortoiseMerge caused the whole
argument instead of just the file name to be quoted in case of file
names with spaces. So TortoiseMerge was passed

"-base:new file.txt"

instead of

-base:"new file.txt"

(including the quotes). To work around this, TortoiseGitMerge does not
require the ":" after the arguments anymore which fixes handling file
names with spaces [2] (as written above).

apply: diagnose incomplete submodule object name better

"git am -3" uses this function to build a tree that records how the
preimage the patch was created from would have looked like. An
abbreviated object name on the index line is ordinarily sufficient
for us to figure out the object name the preimage tree would have
contained, but a change to a submodule by definition shows an object
name of a submodule commit which our repository should not have, and
get_sha1_blob() is not an appropriate way to read it (or get_sha1()
for that matter).

Use get_sha1_hex() and complain if we do not find a full object name
there.

We could read from the payload part of the patch to learn the full
object name of the commit, but the primary user "git rebase" has
been fixed to give us a full object name, so this should suffice
for now.

Earlier, a230949 (am --rebasing: get patch body from commit, not

commit object while rebasing, instead of reading from the rebase-am
front-end. While doing so, it used "git diff-tree" but without
giving it the "--full-index" option.

This does not matter for in-repository objects; during rebasing, any
abbreviated object name should uniquely identify them.

But we may be rebasing a commit that contains a change to a gitlink,
in which case we usually should not have the object (it names a
commit in the submodule). A full object name is necessary to later
reconstruct a fake ancestor index for them.

branch: let branch filters imply --listJeff King Thu, 31 Jan 2013 06:46:11 +0000 (01:46 -0500)

branch: let branch filters imply --list

Currently, a branch filter like `--contains`, `--merged`, or
`--no-merged` is ignored when we are not in listing mode.
For example:

git branch --contains=foo bar

will create the branch "bar" from the current HEAD, ignoring
the `--contains` argument entirely. This is not very
helpful. There are two reasonable behaviors for git here:

1. Flag an error; the arguments do not make sense.

2. Implicitly go into `--list` mode

This patch chooses the latter, as it is more convenient, and
there should not be any ambiguity with attempting to create
a branch; using `--contains` and not wanting to list is
nonsensical.

That leaves the case where an explicit modification option
like `-d` is given. We already catch the case where
`--list` is given alongside `-d` and flag an error. With
this patch, we will also catch the use of `--contains` and
other filter options alongside `-d`.

CodingGuidelines: add Python coding guidelinesJohn Keeping Wed, 30 Jan 2013 20:47:32 +0000 (20:47 +0000)

CodingGuidelines: add Python coding guidelines

These are kept short by simply deferring to PEP-8. Most of the Python
code in Git is already very close to this style (some things in contrib/
are not).

Rationale for version suggestions:

- Amongst the noise in [1], there isn't any disagreement about using
2.6 as a base (see also [2]), although Brandon Casey recently added
support for 2.4 and 2.5 to git-p4 [3].

- Restricting ourselves to 2.6+ makes aiming for Python 3 compatibility
significantly easier [4].

- Advocating Python 3 support in all scripts is currently unrealistic
because:

- 'p4 -G' provides output in a format that is very hard to use with
Python 3 (and its documentation claims Python 3 is unsupported).

- Mercurial does not support Python 3.

- Bazaar does not support Python 3.

- But we should try to make new scripts compatible with Python 3
because all new Python development is happening on version 3 and the
Python community will eventually stop supporting Python 2 [5].

- Python 3.1 is required to support the 'surrogateescape' error handler
for encoding/decodng filenames to/from Unicode strings and Python 3.0
is not longer supported.

Merge branch 'rr/minimal-stat'

Some reimplementations of Git does not write all the stat info back
to the index due to their implementation limitations (e.g. jgit

add: warn when -u or -A is used without pathspecMatthieu Moy Mon, 28 Jan 2013 09:16:33 +0000 (10:16 +0100)

add: warn when -u or -A is used without pathspec

Most Git commands that can be used with or without pathspec operate
tree-wide by default, the pathspec being used to restrict their
scope. A few exceptions are: 'git grep', 'git clean', 'git add -u'
and 'git add -A'. When run in a subdirectory without pathspec, they
operate only on paths in the current directory.

The inconsistency of 'git add -u' and 'git add -A' is particularly
problematic since other 'git add' subcommands (namely 'git add -p'
and 'git add -e') are tree-wide by default. It also means that "git
add -u && git commit" will record a state that is different from
what is recorded with "git commit -a".

Flipping the default now is unacceptable, so let's start training
users to type 'git add -u|-A :/' or 'git add -u|-A .' explicitly, to
prepare for the next steps:

* forbid 'git add -u|-A' without pathspec (like 'git add' without
option)

* much later, maybe, re-allow 'git add -u|-A' without pathspec, that
will add all tracked and modified files, or all files, tree-wide.

A nice side effect of this patch is that it makes the :/ magic
pathspec easier to discover for users.

When the command is called from the root of the tree, there is no
ambiguity and no need to change the behavior, hence no need to warn.

git-remote-testpy: fix path hashing on Python 3John Keeping Sun, 27 Jan 2013 14:50:56 +0000 (14:50 +0000)

git-remote-testpy: fix path hashing on Python 3

When this change was originally made (0846b0c - git-remote-testpy:
hash bytes explicitly , I didn't realise that the "hex" encoding we
chose is a "bytes to bytes" encoding so it just fails with an error
on Python 3 in the same way as the original code.

It is not possible to provide a single code path that works on
Python 2 and Python 3 since Python 2.x will attempt to decode the
string before encoding it, which fails for strings that are not
valid in the default encoding. Python 3.1 introduced the
"surrogateescape" error handler which handles this correctly and
permits a bytes -> unicode -> bytes round-trip to be lossless. As
the original came from reading the filesystem path, we convert them
back into the original bytes encoded in sys.getfilesystemencoding().

At this point Python 3.0 is unsupported so we don't go out of our
way to try to support it.

We need to introduce a new return code for setup_tool to differentiate
between the case of "the selected tool is invalid" and "the selected

This test does a commit that is a pure mode change, submits

the state in p4 as well as the client directory are both
unmodified after the failed submit.

On cygwin, "chmod +x" does nothing, so use the test_chmod
function to modify the index directly too.

Also on cygwin, the executable bit cannot be seen in the
filesystem, so avoid that part of the test. The checks of
p4 state are still valid, though.

git p4: cygwin p4 client does not mark read-only

There are some old versions of p4, compiled for cygwin, that
treat read-only files differently.

Normally, a file that is not open is read-only, meaning that
"test -w" on the file is false. This works on unix, and it works
on windows using the NT version of p4. The cygwin version
of p4, though, changes the permissions, but does not set the
windows read-only attribute, so "test -w" returns false.

git p4 test: newline handlingPete Wyckoff Sun, 27 Jan 2013 03:11:14 +0000 (22:11 -0500)

git p4 test: newline handling

P4 stores newlines in the depos as \n. By default, git does this
too, both on unix and windows. Test to make sure that this stays
true.

Both git and p4 have mechanisms to use \r\n in the working
directory. Exercise these.

git p4: scrub crlf for utf16 files on windowsPete Wyckoff Sun, 27 Jan 2013 03:11:13 +0000 (22:11 -0500)

git p4: scrub crlf for utf16 files on windows

Files of type utf16 are handled with "p4 print" instead of the
normal "p4 -G print" interface due to how the latter does not
produce correct output. See 55aa571 (git-p4: handle utf16
filetype properly, 2011-09-17) for details.

On windows, though, "p4 print" can not be told which line
endings to use, as there is no underlying client, and always
chooses crlf, even for utf16 files. Convert the \r\n into \n
when importing utf16 files.

The fix for this is complex, in that the problem is a property
of the NT version of p4. There are old versions of p4 that
were compiled directly for cygwin that should not be subjected
to text replacement. The right check here, then, is to look
at the p4 version, not the OS version. Note also that on cygwin,
platform.system() is "CYGWIN_NT-5.1" or similar, not "Windows".

Add a function to memoize the p4 version string and use it to
check for "/NT", indicating the Windows build of p4.

git p4: remove unreachable windows \r\n conversion... Pete Wyckoff Sun, 27 Jan 2013 03:11:12 +0000 (22:11 -0500)

git p4: remove unreachable windows \r\n conversion code

Replacing \r\n with \n on windows was added in c1f9197 (Replace
\r\n with \n when importing from p4 on Windows, 2007-05-24), to
work around an oddity with "p4 print" on windows. Text files
are printed with "\r\r\n" endings, regardless of whether they
were created on unix or windows, and regardless of the client
LineEnd setting.

As of d2c6dd3 (use p4CmdList() to get file contents in Python
dicts. This is more robust., 2007-05-23), git-p4 uses "p4 -G
print", which generates files in a raw format. As the native
line ending format if p4 is \n, there will be no \r\n in the
raw text.

Actually, it is possible to generate a text file so that the
p4 representation includes embedded \r\n, even though this is not
normal on either windows or unix. In that case the code would
have mistakenly stripped them out, but now they will be left
intact.

git p4 test: translate windows paths for cygwinPete Wyckoff Sun, 27 Jan 2013 03:11:11 +0000 (22:11 -0500)

git p4 test: translate windows paths for cygwin

Native windows binaries do not understand posix-like
path mapping offered by cygwin. Convert paths to native
using "cygpath --windows" before presenting them to p4d.

This is done using the AltRoots mechanism of p4. Both the
posix and windows forms are put in the client specification,
allowing p4 to find its location by native path even though
the environment reports a different PWD.

Shell operations in tests will use the normal form of $cli,
which will look like a posix path in cygwin, while p4 will
use AltRoots to match against the windows form of the working
directory.

This mechanism also handles the symlink issue that was fixed in
23bd0c9 (git p4 test: use real_path to resolve p4 client
symlinks, 2012-06-27). Now that every p4 client view has
an AltRoots with the real_path in it, explicitly calculating
the real_path elsewhere is not necessary.

git p4 test: start p4d inside its db dir

This will avoid having to do native path conversion for
windows. Also may be a bit cleaner always to know that p4d
has that working directory, instead of wherever the function
was called from.

git p4 test: use client_view in t9806Pete Wyckoff Sun, 27 Jan 2013 03:11:09 +0000 (22:11 -0500)

git p4 test: use client_view in t9806

Use the standard client_view function from lib-git-p4.sh
instead of building one by hand. This requires a bit of
rework, using the current value of $P4CLIENT for the client
name. It also reorganizes the test to isolate changes to
$P4CLIENT and $cli in a subshell.
