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`.

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.

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

avoids excessive revalidation of contents.

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.

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.

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".

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.

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.

When we look up a sha1 object for reading via parse_object() =>
read_sha1_file() => read_object() callpath, we first check
packfiles, and then loose objects. If we still haven't found it, we
re-scan the list of packfiles in `objects/pack`. This final step
ensures that we can co-exist with a simultaneous repack process
which creates a new pack and then prunes the old object.
This extra re-scan usually does not have a performance impact for
two reasons:
1. If an object is missing, then typically the re-scan will find a
new pack, then no more misses will occur. Or if it truly is
missing, then our next step is usually to die().
2. Re-scanning is cheap enough that we do not even notice.
However, these do not always hold. The assumption in (1) is that the
caller is expecting to find the object. This is usually the case,
but the call to `parse_object` in `everything_local` does not follow
this pattern. It is looking to see whether we have objects that the
remote side is advertising, not something we expect to
have. Therefore if we are fetching from a remote which has many refs
pointing to objects we do not have, we may end up re-scanning the
pack directory many times.
Even with this extra re-scanning, the impact is often not noticeable
due to (2); we just readdir() the packs directory and skip any packs
that are already loaded. However, if there are a large number of
packs, even enumerating the directory can be expensive, especially
if we do it repeatedly.
Having this many packs is a good sign the user should run `git gc`,
but it would still be nice to avoid having to scan the directory at
all.

We generally try to run "gc --auto" after any commands that
might introduce a large number of new objects. An obvious
place to do so is after running "fetch", which may introduce
new loose objects or packs (depending on the size of the
fetch).
While an active developer repository will probably
eventually trigger a "gc --auto" on another action (e.g.,
git-rebase), there are two good reasons why it is nicer to
do it at fetch time:
1. Read-only repositories which track an upstream (e.g., a
continuous integration server which fetches and builds,
but never makes new commits) will accrue loose objects
and small packs, but never coalesce them into a more
efficient larger pack.
2. Fetching is often already perceived to be slow to the
user, since they have to wait on the network. It's much
more pleasant to include a potentially slow auto-gc as
part of the already-long network fetch than in the
middle of productive work with git-rebase or similar.

Usually a commit that makes it to logmsg_reencode will have
been parsed, and the commit->buffer struct member will be
valid. However, some code paths will free commit buffers
after having used them (for example, the log traversal
machinery will do so to keep memory usage down).
Most of the time this is fine; log should only show a commit
once, and then exits. However, there are some code paths
where this does not work. At least two are known:
1. A commit may be shown as part of a regular ref, and
then it may be shown again as part of a submodule diff
(e.g., if a repo contains refs to both the superproject
and subproject).
2. A notes-cache commit may be shown during "log --all",
and then later used to access a textconv cache during a
diff.
Lazily loading in logmsg_reencode does not necessarily catch
all such cases, but it should catch most of them. Users of
the commit buffer tend to be either parsing for structure
(in which they will call parse_commit, and either we will
already have parsed, or we will load commit->buffer lazily
there), or outputting (either to the user, or fetching a
part of the commit message via format_commit_message). In
the latter case, we should always be using logmsg_reencode
anyway (and typically we do so via the pretty-print
machinery).
If there are any cases that this misses, we can fix them up
to use logmsg_reencode (or handle them on a case-by-case
basis if that is inappropriate).
Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
The logmsg_reencode function will return the reencoded
commit buffer, or NULL if reencoding failed or no reencoding
was necessary. Since every caller then ends up checking for NULL
and just using the commit's original buffer, anyway, we can
be a bit more helpful and just return that buffer when we
would have returned NULL.
Since the resulting string may or may not need to be freed,
we introduce a logmsg_free, which checks whether the buffer
came from the commit object or not (callers either
implemented the same check already, or kept two separate
pointers, one to mark the buffer to be used, and one for the
to-be-freed string).
Pushing this logic into logmsg_* simplifies the callers, and
will let future patches lazily load the commit buffer in a
single place.

When git-commit is asked to reuse a commit message via "-c",
we call read_commit_message, which looks up the commit and
hands back either the re-encoded result, or a copy of the
original. We make a copy in the latter case so that the
ownership semantics of the return value are clear (in either
case, it can be freed).
However, since we return a "const char *", and since the
resulting buffer's lifetime is the same as that of the whole
program, we never bother to free it at all.
Let's just drop the copy. That saves us a copy in the common
case. While it does mean we leak in the re-encode case, it
doesn't matter, since we are relying on program exit to free
the memory anyway.

"$GIT_EXEC_PATH/mergetools/" rather than the list of command names in
git-mergetool--lib.
Fix this by simply delegating the "--tool-help" argument to the
show_tool_help function in git-mergetool--lib.

TOOL_MODE is set at the top of git-mergetool.sh so there is no need to
set it again in show_tool_help. Removing this lets us re-use
show_tool_help in git-difftool.

ident: do not drop username when reading from /etc/mailname
An earlier conversion from fgets() to strbuf_getline() in the
codepath to read from /etc/mailname to learn the default host-part
of the ident e-mail address forgot that strbuf_getline() stores the
line at the beginning of the buffer just like fgets().
The "username@" the caller has prepared in the strbuf, expecting the
function to append the host-part to it, was lost because of this.

push: finishing touches to explain REJECT_ALREADY_EXISTS better
Now that "already exists" errors are given only when a push tries to
update an existing ref in refs/tags/ hierarchy, we can say "the
tag", instead of "the destination reference", and that is far easier
to understand.
This is harmless in Python 2, which sees the parentheses as redundant
grouping, but is required for Python 3. Since this is the only change
required to make this script just run under Python 3 without needing
2to3 it seems worthwhile.
The case of an empty print must be handled specially because in that
case Python 2 will interpret '()' as an empty tuple and print it as
'()'; inserting an empty string fixes this.

Python 3 forbids unbuffered I/O in text mode. Change the reading of
stdin in git-remote-testpy so that we read the lines as bytes and then
decode them a line at a time.
This allows us to keep the I/O unbuffered in order to avoid
reintroducing the bug fixed by commit 7fb8e16 (git-remote-testgit: fix
race when spawning fast-import).

Under Python 3 'hasher.update(...)' must take a byte string and not a
unicode string. Explicitly encode the argument to this method to hex
bytes so that we don't need to worry about failures to encode that might
occur if we chose a textual encoding.
This changes the directory used by git-remote-testpy for its git mirror
of the remote repository, but this tool should not have any serious
users as it is used primarily to test the Python remote helper
framework.
The use of encode() moves the required Python version forward to 2.0.

svn-fe: allow svnrdump_sim.py to run with Python 3
The changes to allow this script to run with Python 3 are minimal and do
not affect its functionality on the versions of Python 2 that are
already supported (2.4 onwards).

When you have random build artifacts in your build directory, left
behind by running "make" while on another branch, the "git help -a"
command run by __git_list_all_commands in the completion script that
is being tested does not have a way to know that they are not part
of the subcommands this build will ship. Such extra subcommands may
come from the user's $PATH. They will interfere with the tests that
expect a certain prefix to uniquely expand to a known completion.
Instrument the completion script and give it a way for us to tell
what (subset of) subcommands we are going to ship.
Also add a test to "git --help <prefix><TAB>" expansion. It needs
to show not just commands but some selected documentation pages.
push: introduce REJECT_FETCH_FIRST and REJECT_NEEDS_FORCE
When we push to update an existing ref, if:
* the object at the tip of the remote is not a commit; or
* the object we are pushing is not a commit,
it won't be correct to suggest to fetch, integrate and push again,
as the old and new objects will not "merge". We should explain that
the push must be forced when there is a non-committish object is
involved in such a case.
If we do not have the current object at the tip of the remote, we do
not even know that object, when fetched, is something that can be
merged. In such a case, suggesting to pull first just like
non-fast-forward case may not be technically correct, but in
practice, most such failures are seen when you try to push your work
to a branch without knowing that somebody else already pushed to
update the same branch since you forked, so "pull first" would work
as a suggestion most of the time. And if the object at the tip is
not a commit, "pull first" will fail, without making any permanent
damage. As a side effect, it also makes the error message the user
will get during the next "push" attempt easier to understand, now
the user is aware that a non-commit object is involved.
In these cases, the current code already rejects such a push on the
client end, but we used the same error and advice messages as the
ones used when rejecting a non-fast-forward push, i.e. pull from
there and integrate before pushing again.
Introduce new rejection reasons and reword the messages
appropriately.
