In the case where a program was not found, it was still the task of the
caller to report an error to the user. Usually, this is an interesting case
but only few callers actually reported a specific error (though many call
sites report a generic error message regardless of the cause).
With this change the error is reported by run_command, but since there is
one call site in git.c that does not want that, an option is added to
struct child_process, which is used to turn the error off.

Signed-off-by: Junio C Hamano <gitster@pobox.com>
The motivation for this change is that system call failures are serious
errors that should be reported to the user, but only few callers took the
burden to decode the error codes that the functions returned into error
messages.
If at all, then only an unspecific error message was given. A prominent
example is this:
$ git upload-pack . | :
fatal: unable to run 'git-upload-pack'
In this example, git-upload-pack, the external command invoked through the
git wrapper, dies due to SIGPIPE, but the git wrapper does not bother to
report the real cause. In fact, this very error message is copied to the
syslog if git-daemon's client aborts the connection early.
With this change, system call failures are reported immediately after the
failure and only a generic failure code is returned to the caller. In the
above example the error is now to the point:
$ git upload-pack . | :
error: git-upload-pack died of signal
Note that there is no error report if the invoked program terminated with
a non-zero exit code, because it is reasonable to expect that the invoked
program has already reported an error. (But many run_command call sites
nevertheless write a generic error message.)
There was one special return code that was used to identify the case where
run_command failed because the requested program could not be exec'd. This
special case is now treated like a system call failure with errno set to
ENOENT. No error is reported in this case, because the call site in git.c
expects this as a normal result. Therefore, the callers that carefully
decoded the return value still check for this condition.

As a general guideline, functions in git's code return zero to indicate
success and negative values to indicate failure. The run_command family of
functions followed this guideline. But there are actually two different
kinds of failure:
- failures of system calls;
- non-zero exit code of the program that was run.
Usually, a non-zero exit code of the program is a failure and means a
failure to the caller. Except that sometimes it does not. For example, the
exit code of merge programs (e.g. external merge drivers) conveys
information about how the merge failed, and not all exit calls are
actually failures.
Furthermore, the return value of run_command is sometimes used as exit
code by the caller.
This change arranges that the exit code of the program is returned as a
positive value, which can now be regarded as the "result" of the function.
System call failures continue to be reported as negative values.

For some reason, MinGW's bash cannot reliably detect failure of the child
process if a negative value is passed to exit(). This fixes it by
truncating the exit code in all calls of exit().
This issue was worked around in run_builtin() of git.c (2488df84 builtin
run_command: do not exit with -1, 2007-11-15). This workaround is no longer
necessary and is reverted.

When creating a new argv array from a configured alias and the supplied
command line arguments, the new argv was allocated with one element too
many. Since the first element of the original argv array is skipped when
copying it to the new_argv, the number of elements that are allocated
should be reduced by one. 'count' is the number of elements that new_argv
contains, and *argcp is the number of elements in the original argv array.
So the total allocation (including the terminating NULL entry) for the
new_argv array should be:
count + (*argcp - 1) + 1
Also, the explicit assignment of the NULL terminating entry can be avoided
by just copying it over from the original argv array.

We used to simply try calling execvp(); if it succeeded, then we were done
and the new program was running. If it didn't, then we knew that it wasn't
a valid command.
Unfortunately, this interacted badly with the new pager handling. Now that
git remains the parent process and the pager is spawned, git has to hang
around until the pager is finished. We install an atexit handler to do
this, but that handler never gets called if we successfully run execvp.
You could see this behavior by running any dashed external using a pager
(e.g., "git -p stash list"). The command finishes running, but the pager
is still going. In the case of less, it then gets an error reading from
the terminal and exits, potentially leaving the terminal in a broken state
(and not showing the output).
This patch just uses run_command() to try running the dashed external. The
parent git process then waits for the external process to complete and
then handles the pager cleanup as it would for an internal command.

help_unknown_cmd() is able to autocorrect a command to an alias, and not

alias.
This commit makes the autocorrected command go through handle_alias(), once
handle_internal_command() and execv_dashed_external() have been tried. Since
this is done twice in main() now, moved that logic to a new run_argv()
function.
Also, print the same "Expansion of alias 'x' failed" message when the alias
was autocorrected, rather than a generic "Failed to run command 'x'".

There is great debate over whether some commands should set
up a pager automatically. This patch allows individuals to
set their own pager preferences for each command, overriding
the default. For example, to disable the pager for git
status:
git config pager.status false
If "--pager" or "--no-pager" is specified on the command
line, it takes precedence over the config option.
There are two caveats:
- you can turn on the pager for plumbing commands.
Combined with "core.pager = always", this will probably
break a lot of things. Don't do it.
- This only works for builtin commands. The reason is
somewhat complex:
Calling git_config before we do setup_git_directory
has bad side effects, because it wants to know where
the git_dir is to find ".git/config". Unfortunately,
we cannot call setup_git_directory indiscriminately,
because some builtins (like "init") break if we do.
For builtins, this is OK, since we can just wait until
after we call setup_git_directory. But for aliases, we
don't know until we expand (recursively) which command
we're doing. This should not be a huge problem for
aliases, which can simply use "--pager" or "--no-pager"
in the alias as appropriate.
For external commands, however, we don't know we even
have an external command until we exec it, and by then
it is too late to check the config.
An alternative approach would be to have a config mode
where we don't bother looking at .git/config, but only
at the user and system config files. This would make the
behavior consistent across builtins, aliases, and
external commands, at the cost of not allowing per-repo
pager config for at all.

Attributes can be specified at three different places: the internal
table of default values, the file $GIT_DIR/info/attributes and files
named .gitattributes in the work tree. Since bare repositories don't
have a work tree, git should ignore any .gitattributes files there.
This patch makes git do that, so the only way left for a user to specify
attributes in a bare repository is the file info/attributes (in addition
to changing the defaults and recompiling).
In addition, git-check-attr is now allowed to run without a work tree.

This converts git_config_alias to the public alias_lookup

The only differences in behavior should be:
- git checkout -m with non-trivial merging won't print out
merge-recursive messages (see the change in t7201-co.sh)
- git checkout -- paths... will give a sensible error message if
HEAD is invalid as a commit.
- some intermediate states which were written to disk in the shell
version (in particular, index states) are only kept in memory in
this version, and therefore these can no longer be revealed by
later write operations becoming impossible.
- when we change branches, we discard MERGE_MSG, SQUASH_MSG, and
rr-cache/MERGE_RR, like reset always has.
I'm not 100% sure I got the merge recursive setup exactly right; the
base for a non-trivial merge in the shell code doesn't seem
theoretically justified to me, but I tried to match it anyway, and the
tests all pass this way.
Other than these items, the results should be identical to the shell
version, so far as I can tell.

This makes write_tree_from_memory(), which writes the active cache as
a tree and returns the struct tree for it, available to other code. It
also makes available merge_trees(), which does the internal merge of
two trees with a known base, and merge_recursive(), which does the
recursive internal merge of two commits with a list of common
ancestors.
The first two of these will be used by checkout -m, and the third is
presumably useful in general, although the implementation of checkout
-m which entirely matches the behavior of the shell version does not
use it (since it ignores the difference of ancestry between the old
branch and the new branch).

Since signed tags' signatures will not necessarily be valid (think

This replaces git-clean.sh with builtin-clean.c, and moves

This also introduces a change in behavior when removing directories
explicitly specified as a path. For example currently:
1. When dir has only untracked files, these two behave differently:
$ git clean -n dir
$ git clean -n dir/
the former says "Would not remove dir/", while the latter would say
"Would remove dir/untracked" for all paths under it, but not the
directory itself.
With -d, the former would stop refusing, however since the user
explicitly asked to remove the directory the -d is no longer required.
2. When there are more parameters:
$ git clean -n dir foo
$ git clean -n dir/ foo
both cases refuse to remove dir/ unless -d is specified. Once again
since both cases requested to remove dir the -d is no longer required.

This changes a few small bits of behavior:
branch.<name>.merge is parsed as if it were the lhs of a fetch
refspec, and does not have to exactly match the actual lhs of a
refspec, so long as it is a valid abbreviation for the same ref.
branch.<name>.merge is no longer ignored if the remote is configured
with a branches/* file. Neither behavior is useful, because there can
only be one ref that gets fetched, but this is more consistant.
Also, fetch prints different information to standard out.

"ls-files" to check for unmerged files, "read-tree" for resetting
the index file in "mixed" and "hard" resets, and "update-index" to
refresh at the end in the "mixed" reset and also for the option that
gets selected paths into the index.
The reset option with paths was implemented by Johannes Schindelin.
Since the option that gets selected paths into the index is not
a "reset" like the others because it does not change the HEAD at all,
now the command is showing a warning when the "--mixed" option
is supplied for that purpose.
The following table shows the behaviour of "git reset" for

Here is my attempt to fix this with a minimally intrusive patch.
* As "git --bare init" cannot tell if it was called with --bare or
just "GIT_DIR=. git init", I added an explicit assignment of
is_bare_repository_cfg on the codepath for "git --bare".
* GIT_WORK_TREE alone without GIT_DIR does not make any sense,
nor GIT_WORK_TREE with an explicit "git --bare". Catch that
mistake. It might make sense to move this check to "git.c"
side as well, but I tried to shoot for the minimum change for
now.
* Some scripts, especially from the olden days, rely on
traditional GIT_DIR behaviour in "git init". Namely, these
are some notable patterns:
(create a bare repository)
- mkdir some.git && cd some.git && GIT_DIR=. git init
- mkdir some.git && cd some.git && git --bare init
(create a non-bare repository)
- mkdir .git && GIT_DIR=.git git init
- mkdir .git && GIT_DIR=`pwd`/.git git init
This comes with a new test script and also passes the existing
test suite, but there may be cases that are still broken with
the current tip of master and this patch does not yet fix. I'd
appreciate help in straightening this mess out.

The old version of work-tree support was an unholy mess, barely readable,
and not to the point.
For example, why do you have to provide a worktree, when it is not used?
As in "git status". Now it works.
Another riddle was: if you can have work trees inside the git dir, why
are some programs complaining that they need a work tree?
IOW it is allowed to call
$ git --git-dir=../ --work-tree=. bla
when you really want to. In this case, you are both in the git directory
and in the working tree. So, programs have to actually test for the right
thing, namely if they are inside a working tree, and not if they are
inside a git directory.
Also, GIT_DIR=../.git should behave the same as if no GIT_DIR was
specified, unless there is a repository in the current working directory.
It does now.
The logic to determine if a repository is bare, or has a work tree
(tertium non datur), is this:
--work-tree=bla overrides GIT_WORK_TREE, which overrides core.bare = true,
which overrides core.worktree, which overrides GIT_DIR/.. when GIT_DIR
ends in /.git, which overrides the directory in which .git/ was found.
In related news, a long standing bug was fixed: when in .git/bla/x.git/,
which is a bare repository, git formerly assumed ../.. to be the
appropriate git dir. This problem was reported by Shawn Pearce to have
caused much pain, where a colleague mistakenly ran "git init" in "/" a
long time ago, and bare repositories just would not work.

This replaces "git-verify-tag.sh" with "builtin-verify-tag.c".
Testing relies on the "git tag -v" tests calling this command.
A temporary file is needed when calling to gpg, because git is
already creating detached signatures (gpg option -b) to sign tags
(instead of leaving gpg to add the signature to the file by itself),
and those signatures need to be supplied in a separate file to be
verified by gpg.
The program uses git_mkstemp to create that temporary file needed by
gpg, instead of the previously used "$GIT_DIR/.tmp-vtag", in order to
allow the command to be used in read-only repositories, and also
prevent other instances of git to read or remove the same file.
Signal SIGPIPE is ignored because the program sometimes was
terminated because that signal when writing the input for gpg.
The command now can receive many tag names to be verified.
Documentation is also updated here to reflect this new behaviour.

There are some minor changes in the behaviour of "git tag" here:
"git tag -v" now can get more than one tag to verify, like "git tag -d" does,
"git tag" with no arguments prints all tags, more like "git branch" does,
and "git tag -n" also prints all tags with annotations (without needing -l).
Tests and documentation were also updated to reflect these changes.
The program is currently calling the script "git verify-tag" for verify.

This switches the checks around upon the exit codepath of the
git wrapper, so that we may recover at least non-transient errors.
It's still not perfect. As I've been harping on, stdio simply isn't very
good for error reporting. For example, if an IO error happened, you'd want
to see EIO, wouldn't you? And yes, that's what the kernel would return.
However, with buffered stdio (and flushing outside of our control), what
would likely happen is that some intermediate error return _does_ return
EIO, but then the kernel might decide to re-mount the filesystem read-only
due to the error, and the actual *report* for us might be
"write failure on standard output: read-only filesystem"
which lost the EIO.

Aliases changing environment variables (GIT_DIR or

git has to use GIT_DIR to read the aliases from the config.
After running handle_options for the alias the options of the
alias may have changed environment variables. Depending on
the implementation of setenv the memory location obtained
through getenv earlier may contain the old value or the new

setup_gdg is used as abbreviation for setup_git_directory_gently.
The work tree can be specified using the environment variable
GIT_WORK_TREE and the config option core.worktree (the environment
variable has precendence over the config option). Additionally
there is a command line option --work-tree which sets the
environment variable.
setup_gdg does the following now:
GIT_DIR unspecified
repository in .git directory
parent directory of the .git directory is used as work tree,
GIT_WORK_TREE is ignored
GIT_DIR unspecified
repository in cwd
GIT_DIR is set to cwd
see the cases with GIT_DIR specified what happens next and
also see the note below
GIT_DIR specified
GIT_WORK_TREE/core.worktree unspecified
cwd is used as work tree
GIT_DIR specified
GIT_WORK_TREE/core.worktree specified
the specified work tree is used
Note on the case where GIT_DIR is unspecified and repository is in cwd:
GIT_WORK_TREE is used but is_inside_git_dir is always true.
I did it this way because setup_gdg might be called multiple
times (e.g. when doing alias expansion) and in successive calls
setup_gdg should do the same thing every time.
Meaning of is_bare/is_inside_work_tree/is_inside_git_dir:
(1) is_bare_repository
A repository is bare if core.bare is true or core.bare is
unspecified and the name suggests it is bare (directory not
named .git). The bare option disables a few protective
checks which are useful with a working tree. Currently
this changes if a repository is bare:

git gc packs the refs

(2) is_inside_work_tree
True if the cwd is inside the associated working tree (if there
is one), false otherwise.
(3) is_inside_git_dir
True if the cwd is inside the git directory, false otherwise.
Before this patch is_inside_git_dir was always true for bare
repositories.
When setup_gdg finds a repository git_config(git_default_config) is
always called. This ensure that is_bare_repository makes use of
core.bare and does not guess even though core.bare is specified.
inside_work_tree and inside_git_dir are set if setup_gdg finds a
repository. The is_inside_work_tree and is_inside_git_dir functions
will die if they are called before a successful call to setup_gdg.

This adds the basic infrastructure to assign attributes to
paths, in a way similar to what the exclusion mechanism does
based on $GIT_DIR/info/exclude and .gitignore files.
An attribute is just a simple string that does not contain any
whitespace. They can be specified in $GIT_DIR/info/attributes
file, and .gitattributes file in each directory.
Each line in these files defines a pattern matching rule.
Similar to the exclusion mechanism, a later match overrides an
earlier match in the same file, and entries from .gitattributes
file in the same directory takes precedence over the ones from
parent directories. Lines in $GIT_DIR/info/attributes file are
used as the lowest precedence default rules.
A line is either a comment (an empty line, or a line that begins
with a '#'), or a rule, which is a whitespace separated list of
tokens. The first token on the line is a shell glob pattern.
The rest are names of attributes, each of which can optionally
be prefixed with '!'. Such a line means "if a path matches this
glob, this attribute is set (or unset -- if the attribute name
is prefixed with '!'). For glob matching, the same "if the
pattern does not have a slash in it, the basename of the path is
matched with fnmatch(3) against the pattern, otherwise, the path
is matched with the pattern with FNM_PATHNAME" rule as the
exclusion mechanism is used.
This does not define what an attribute means. Tying an
attribute to various effects it has on git operation for paths
that have it will be specified separately.

Some workflows require use of repositories on machines that cannot be
connected, preventing use of git-fetch / git-push to transport objects and
references between the repositories.
git-bundle provides an alternate transport mechanism, effectively allowing
git-fetch and git-pull to operate using sneakernet transport. `git-bundle
create` allows the user to create a bundle containing one or more branches
or tags, but with specified basis assumed to exist on the target
repository. At the receiving end, git-bundle acts like git-fetch-pack,
allowing the user to invoke git-fetch or git-pull using the bundle file as
the URL. git-fetch and git-ls-remote determine they have a bundle URL by
checking that the URL points to a file, but are otherwise unchanged in
operation with bundles.
The original patch was done by Mark Levedahl <mdl123@verizon.net>.
It was updated to make git-bundle a builtin, and get rid of the tar
format: now, the first line is supposed to say "# v2 git bundle", the next
lines either contain a prerequisite ("-" followed by the hash of the
needed commit), or a ref (the hash of a commit, followed by the name of
the ref), and finally the pack. As a result, the bundle argument can be
"-" now.

With this flag and given two paths, git-diff-files behaves as a GNU diff
lookalike (plus the git goodies like --check, colour, etc.). This flag
is also available in git-diff. It also works outside of a git repository.
In addition, if git-diff{,-files} is called without revision or stage
parameter, and with exactly two paths at least one of which is not tracked,
the default is --no-index.
So, you can now say
git diff /etc/inittab /etc/fstab
and it actually works!
This also unifies the duplicated argument parsing between cmd_diff_files()
and builtin_diff_files().

This mechanically converts strncmp() to use prefixcmp(), but only when
the parameters match specific patterns, so that they can be verified
easily. Leftover from this will be fixed in a separate step, including
idiotic conversions like
if (!strncmp("foo", arg, 3))
=>
if (!(-prefixcmp(arg, "foo")))
This was done by using this script in px.perl
#!/usr/bin/perl -i.bak -p
if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) {
s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|;
}
if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) {
s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|;
}
and running:
$ git grep -l strncmp -- '*.c' | xargs perl px.perl

If the user tries to run a porcelainish command which requires
a working directory in a bare repository they may get unexpected
results which are difficult to predict and may differ from command
to command.
Instead we should detect that the current repository is a bare
repository and refuse to run the command there, as there is no
working directory associated with it.
