bisect: error out when passing bad path parameters
* cc/maint-bisect-paths:
bisect: error out when passing bad path parameters
bisect: error out when passing bad path parameters
As reported by Mark Lodato, "git bisect", when it was started with
path parameters that match no commit was kind of working without
taking account of path parameters and was reporting something like:
Bisecting: -1 revisions left to test after this (roughly 0 steps)
It is more correct and safer to just error out in this case, before
displaying the revisions left, so this patch does just that.
Note that this bug is very old, it exists at least since v1.5.5.
And it is possible to detect that case earlier in the bisect
algorithm, but it is not clear that it would be an improvement to
error out earlier, on the contrary it may change the behavior of
"git rev-list --bisect-all" for example, which is currently correct.

Makefile: clarify definition of TEST_OBJS
The definition of TEST_OBJS in commit daa99a91 (Makefile: make sure
test helpers are rebuilt when headers change, 2010-01-26) moved a use
of $X to before the platform-specific section where it gets defined.
There are at least two ways to fix that:
- Change the definition of TEST_OBJS to use the = delayed
evaluation operator. This way, one need not worry about $(X)
needing to be defined before TEST_OBJS is set.
- Move the definition of TEST_OBJS to below the definition of $X.
Carry out the second. The later site of definition makes the code more
readable, since now a reader only has to look down one line to see what
TEST_OBJS is meant to be used for.
Oddly enough, with or without this change the behavior of the Makefile
is the same. Since TEST_PROGRAMS is defined with delayed evaluation,
the value of
TEST_OBJS := $(patsubst test-%$X,test-%.o,$(TEST_PROGRAMS))
is independent of the value of $X when it is evaluated: the $X in the
pattern and the $X in $(TEST_PROGRAMS) will simply always cancel out.
Make sure $X has the expected expansion anyway to make the code and
the reader’s sanity more robust in the face of future changes.

submodules: ensure clean environment when operating in a submodule
git-submodule used to take care of clearing GIT_DIR whenever it operated
on a submodule index or configuration, but forgot to unset GIT_WORK_TREE
or other repo-local variables. This would lead to failures e.g. when
GIT_WORK_TREE was set.
This only happened in very unusual contexts such as operating on the
main worktree from outside of it, but since "git-gui: set GIT_DIR and
GIT_WORK_TREE after setup" (a9fa11fe5bd5978bb) such failures could also

git-submodule used to take care of clearing GIT_DIR whenever it operated
on a submodule index or configuration, but forgot to unset GIT_WORK_TREE
or other repo-local variables. This would lead to failures e.g. when
GIT_WORK_TREE was set.
This only happened in very unusual contexts such as operating on the
main worktree from outside of it, but since "git-gui: set GIT_DIR and
GIT_WORK_TREE after setup" (a9fa11fe5bd5978bb) such failures could also
be provoked by invoking an external tool such as "git submodule update"
from the Git Gui in a standard setup.

fetch --all/--multiple: keep all the fetched branch information
Since "git fetch" learned "--all" and "--multiple" options, it has become
tempting for users to say "git pull --all". Even though it may fetch from
remotes that do not need to be fetched from for merging with the current
branch, it is handy.
"git fetch" however clears the list of fetched branches every time it
contacts a different remote. Unless the current branch is configured to
merge with a branch from a remote that happens to be the last in the list
of remotes that are contacted, "git pull" that fetches from multiple
remotes will not be able to find the branch it should be merging with.
Make "fetch" clear FETCH_HEAD (unless --append is given) and then append
the list of branches fetched to it (even when --append is not given). That
way, "pull" will be able to find the data for the branch being merged in
FETCH_HEAD no matter where the remote appears in the list of remotes to be
contacted by "git fetch".

transport->progress: use flag authoritatively
Set transport->progress in transport.c::transport_set_verbosity() after
checking for the appropriate conditions (eg. --progress, isatty(2)),
and thereafter use it without having to check again.
The rules used are as follows (processing aborts when a rule is
satisfied):
1. Report progress, if force_progress is 1 (ie. --progress).
2. Don't report progress, if verbosity < 0 (ie. -q/--quiet).
3. Report progress if isatty(2) is 1.
This changes progress reporting behaviour such that if both --progress
and --quiet are specified, progress is reported.
In two areas, the logic to determine whether to *not* show progress is
changed to simply use the negation of transport->progress. This changes
behaviour in some ways (see previous paragraph for details).

Shell command aliases can get rather complex, and the completion

The current completion script does not allow this, because if it

for the aliased git command (in case it can determine the aliased git
command, of course). With this patch the completion script will first
search for a completion function for the command given on the command
line, be it a git command, a custom git command of the user, or an
alias, and invoke that function to perform the completion. This has
no effect on git commands, because they can not be aliased anyway. If
it is an alias and there is a completion function for that alias (e.g.
_git_foo() for the alias 'foo'), then it will be invoked to perform
completion, allowing users to provide custom completion functions for
aliases. If such a completion function can not be found, only then
will the completion script check whether the command given on the
command line is an alias or not, and proceed as usual (i.e. find out
the aliased git command and provide completion for it).

bash: support user-supplied completion scripts for user's git commands
The bash completion script already provides support to complete
aliases, options and refs for aliases (if the alias can be traced back
to a supported git command by __git_aliased_command()), and the user's
custom git commands, but it does not support the options of the user's
custom git commands (of course; how could it know about the options of
a custom git command?). Users of such custom git commands could
extend git's bash completion script by writing functions to support
their commands, but they might have issues with it: they might not
have the rights to modify a system-wide git completion script, and
they will need to track and merge upstream changes in the future.
This patch addresses this by providing means for users to supply
custom completion scriplets for their custom git commands without
modifying the main git bash completion script.
Instead of having a huge hard-coded list of command-completion
function pairs (in _git()), the completion script will figure out
which completion function to call based on the command's name. That
is, when completing the options of 'git foo', the main completion
script will check whether the function '_git_foo' is declared, and if
declared, it will invoke that function to perform the completion. If
such a function is not declared, it will fall back to complete file
names. So, users will only need to provide this '_git_foo' completion
function in a separate file, source that file, and it will be used the
next time they press TAB after 'git foo '.
There are two git commands (stage and whatchanged), for which the
completion functions of other commands were used, therefore they
got their own completion function.

bash: improve aliased command recognition
To support completion for aliases, the completion script tries to
figure out which git command is invoked by an alias. Its
implementation in __git_aliased_command() is rather straightforward:
it returns the first word from the alias. For simple aliases starting
with the git command (e.g. alias.last = cat-file commit HEAD) this
gives the right results. Unfortunately, it does not work with shell
command aliases, which can get rather complex, as illustrated by one
of Junio's aliases:
[alias]
lgm = "!sh -c 'GIT_NOTES_REF=refs/notes/amlog git log \"$@\" || :' -"
In this case the current implementation returns "!sh" as the aliased
git command, which is obviosly wrong.
The full parsing of a shell command alias like that in the completion
code is clearly unfeasible. However, we can easily improve on aliased
command recognition by eleminating stuff that is definitely not a git
command: shell commands (anything starting with '!'), command line
options (anything starting with '-'), environment variables (anything
with a '=' in it), and git itself. This way the above alias would be
handled correctly, and the completion script would correctly recognize
"log" as the aliased git command.
Of course, this solution is not perfect either, and could be fooled
easily. It's not hard to construct an alias, in which a word does not
match any of these filter patterns, but is still not a git command
(e.g. by setting an environment variable to a value which contains
spaces). It may even return false positives, when the output of a git
command is piped into an other git command, and the second gets the
command line options via $@, but options for the first one are
offered. However, the following patches will enable the user to
supply custom completion scripts for aliases, which can be used to
remedy these problematic cases.

Print RUNTIME_PREFIX warning only when GIT_TRACE is set
When RUNTIME_PREFIX is enabled, the installation prefix is derived by
trying a limited set of known locations where the git executable can
reside. If none of these is found, a warning is emitted.
When git is built in a directory that matches neither of these known names,
the warning would always be emitted when the uninstalled executable is run.
This is a problem on Windows, where gitk picks the uninstalled git when
invoked from the build directory and gets confused by the warning.
Print the warning only when GIT_TRACE is set.

move encode_in_pack_object_header() to a better place
Commit 1b22b6c897 made duplicated versions of encode_header() into a
common version called encode_in_pack_object_header(). There is however
a better location that sha1_file.c for such a function though, as
sha1_file.c contains nothing related to the creation of packs, and
it is quite populated already.
Also the comment that was moved to the header file should really remain
near the function as it covers implementation details and provides no

add-interactive: fix bogus diff header line ordering
When we look at a patch for adding hunks interactively, we
first split it into a header and a list of hunks. Some of
the header lines, such as mode changes and deletion, however,
become their own selectable hunks. Later when we reassemble
the patch, we simply concatenate the header and the selected
hunks. This leads to patches like this:
diff --git a/file b/file
index d95f3ad..0000000
--- a/file
+++ /dev/null
deleted file mode 100644
@@ -1 +0,0 @@
-content
Notice how the deletion comes _after_ the ---/+++ lines,
when it should come before.
In many cases, we can get away with this as git-apply
accepts the slightly bogus input. However, in the specific
case of a deletion line that is being applied via "apply
-R", this malformed patch triggers an assert in git-apply.
This comes up when discarding a deletion via "git checkout
-p".
Rather than try to make git-apply accept our odd input,
let's just reassemble the patch in the correct order.

Use git_mkstemp_mode and xmkstemp_mode in odb_mkstemp, not chmod later.
We used to create 0600 files, and then use chmod to set the group and
other permission bits to the umask. This usually has the same effect
as a normal file creation with a umask.
But in the presence of ACLs, the group permission plays the role of
the ACL mask: the "g" bits of newly created files are chosen according
to default ACL mask of the directory, not according to the umask, and
doing a chmod() on these "g" bits affect the ACL's mask instead of
actual group permission.
In other words, creating files with 0600 and then doing a chmod to the
umask creates files which are unreadable by users allowed in the
default ACL. To create the files without breaking ACLs, we let the
umask do it's job at the file's creation time, and get rid of the
later chmod.

Pagers that do not consume their input are dangerous: for example,

$ echo $?

The only reason these tests were able to work before was that
'git log' would write to the pipe (and not fill it) before the
pager had time to terminate and close the pipe.
Fix it by using a program that consumes its input, namely wc (as

sha1_file: be paranoid when creating loose objects
We don't want the data being deflated and stored into loose objects
to be different from what we expect. While the deflated data is
protected by a CRC which is good enough for safe data retrieval
operations, we still want to be doubly sure that the source data used
at object creation time is still what we expected once that data has
been deflated and its CRC32 computed.
The most plausible data corruption may occur if the source file is
modified while Git is deflating and writing it out in a loose object.
Or Git itself could have a bug causing memory corruption. Or even bad
RAM could cause trouble. So it is best to make sure everything is
coherent and checksum protected from beginning to end.
To do so we compute the SHA1 of the data being deflated _after_ the
deflate operation has consumed that data, and make sure it matches
with the expected SHA1. This way we can rely on the CRC32 checked by
the inflate operation to provide a good indication that the data is still
coherent with its SHA1 hash. One pathological case we ignore is when
the data is modified before (or during) deflate call, but changed back
before it is hashed.
There is some overhead of course. Using 'git add' on a set of large files:
Before:
real 0m25.210s
user 0m23.783s
sys 0m1.408s
After:
real 0m26.537s
user 0m25.175s
sys 0m1.358s
The overhead is around 5% for full data coherency guarantee.

t7006-pager: if stdout is not a terminal, make a new one
Testing pagination requires (fake or real) access to a terminal so we
can see whether the pagination automatically kicks in, which makes it
hard to get good coverage when running tests without --verbose. There
are a number of ways to work around that:
- Replace all isatty calls with calls to a custom xisatty wrapper
that usually checks for a terminal but can be overridden for tests.
This would be workable, but it would require implementing xisatty
separately in three languages (C, shell, and perl) and making sure
that any code that is to be tested always uses the wrapper.
- Redirect stdout to /dev/tty. This would be problematic because
there might be no terminal available, and even if a terminal is
available, it might not be appropriate to spew output to it.
- Create a new pseudo-terminal on the fly and capture its output.
This patch implements the third approach.
The new test-terminal.perl helper uses IO::Pty from Expect.pm to create
a terminal and executes the program specified by its arguments with
that terminal as stdout. If the IO::Pty module is missing or not
working on a system, the test script will maintain its old behavior
(skipping most of its tests unless GIT_TEST_OPTS includes --verbose).

Testing pagination requires (fake or real) access to a terminal so we
can see whether the pagination automatically kicks in, which makes it
hard to get good coverage when running tests without --verbose. There
are a number of ways to work around that:
- Replace all isatty calls with calls to a custom xisatty wrapper
that usually checks for a terminal but can be overridden for tests.
This would be workable, but it would require implementing xisatty
separately in three languages (C, shell, and perl) and making sure
that any code that is to be tested always uses the wrapper.
- Redirect stdout to /dev/tty. This would be problematic because
there might be no terminal available, and even if a terminal is
available, it might not be appropriate to spew output to it.

cherry_pick_list: quit early if one side is empty
The --cherry-pick logic starts by counting the commits on each side,
so that it can filter away commits on the bigger one. However, so
far it missed an opportunity for optimization: it doesn't need to do
any work if either side is empty.
This in particular helps the common use-case 'git rebase -i HEAD~$n':
it internally uses --cherry-pick, but since HEAD~$n is a direct
ancestor the left side is always empty.

tests: Add tests for automatic use of pager
Git’s automatic pagination support has some subtleties. Add some
tests to make sure we don’t break:
- when git will use a pager by default;
- the effect of the --paginate and --no-pager options;
- the effect of pagination on use of color;
- how the choice of pager is configured.
This does not yet test:
- use of pager by scripted commands (git svn and git am);
- effect of the pager.* configuration variables;
- setting of the LESS variable.
Some features involve checking whether stdout is a terminal, so many
of these tests are skipped unless output is passed through to the
terminal (i.e., unless $GIT_TEST_OPTS includes --verbose).
The immediate purpose for these tests was to avoid making things worse
after the breakage from my jn/editor-pager series (see commit 376f39,
2009-11-20). Thanks to Sebastian Celis <sebastian@sebastiancelis.com>
for the report.

Documentation: pack-objects: Clarify --local's semantics.
The current documentation suggests that --local also ignores any
objects in local packs, which is incorrect. Change the language to be
clearer and more parallel to the other options that ignore objects.
While we're at it, fix a trivial error in --incremental's
documentation.

utf8.c: speculatively assume utf-8 in strbuf_add_wrapped_text()
is_utf8() works by calling utf8_width() for each character at the
supplied location. In strbuf_add_wrapped_text(), we do that anyway
while wrapping the lines. So instead of checking the encoding
beforehand, optimistically assume that it's utf-8 and wrap along
until an invalid character is hit, and when that happens start over.
This pays off if the text consists only of valid utf-8 characters.
The following command was run against the Linux kernel repo with
git 1.7.0:
$ time git log --format='%b' v2.6.32 >/dev/null
real 0m2.679s
user 0m2.580s
sys 0m0.100s
$ time git log --format='%w(60,4,8)%b' >/dev/null
real 0m4.342s
user 0m4.230s
sys 0m0.110s
And with this patch series:
$ time git log --format='%w(60,4,8)%b' >/dev/null
real 0m3.741s
user 0m3.630s
sys 0m0.110s
So the cost of wrapping is reduced to 70% in this case.
