2010-01-15grep: prepare to run outside of a work treeLibravatar Junio C Hamano1-1/+1
This moves the call to setup_git_directory() for running "grep" from the "git" wrapper to the implementation of the "grep" subcommand. A new variable "use_index" is always true at this stage in the series, and when it is on, we require that we are in a directory that is under git control. To make sure we die the same way, we make a second call into setup_git_directory() when we detect this situation. Signed-off-by: Junio C Hamano <gitster@pobox.com>

This has the same effect as --no-replace-objects option; git ignores the replace refs. When --no-replace-objects option is passed to git, this environment variable is set to "1" and exported to subprocesses in order to propagate the same setting. It is useful for example for scripts, as the git commands used in them can now be aware that they must not read replace refs.

2009-10-13git: add --no-replace-objects option to disable replacingLibravatar Christian Couder1-1/+3
Commit dae556b (environment: add global variable to disable replacement) adds a variable to enable/disable replacement, and it is enabled by default for most commands. So there is no way to disable it for some commands, which is annoying when we want to get information about a commit that has been replaced. For example: $ git cat-file -p N would output information about the replacement commit if commit N is replaced. With the "--no-replace-objects" option that this patch adds it is possible to get information about the original commit using: $ git --no-replace-objects cat-file -p N While at it, let's add some documentation about this new option in the "git replace" man page too.

2009-07-06run_command: report failure to execute the program, but optionally don'tLibravatar Johannes Sixt1-1/+1
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.

2009-07-06run_command: report system call errors instead of returning error codesLibravatar Johannes Sixt1-5/+1
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. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-07-05run_command: return exit code as positive valueLibravatar Johannes Sixt1-2/+2
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. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-07-05MinGW: truncate exit()'s argument to lowest 8 bitsLibravatar Johannes Sixt1-1/+1
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.

2009-06-30git.c: avoid allocating one-too-many elements for new argv arrayLibravatar Brandon Casey1-2/+1
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.

This command can only be used now to list replace refs in "refs/replace/" and to delete them. The option to list replace refs is "-l". The option to delete replace refs is "-d". The behavior should be consistent with how "git tag" and "git branch" are working.

2009-04-05bisect--helper: implement "git bisect--helper"Libravatar Christian Couder1-0/+1
This patch implements a new "git bisect--helper" builtin plumbing command that will be used to migrate "git-bisect.sh" to C. We start by implementing only the "--next-vars" option that will read bisect refs from "refs/bisect/", and then compute the next bisect step, and output shell variables ready to be eval'ed by the shell. At this step, "git bisect--helper" ignores the paths that may have been put in "$GIT_DIR/BISECT_NAMES". This will be fixed in a later patch.

2009-01-28git: use run_command() to execute dashed externalsLibravatar Jeff King1-4/+13
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 only to internal or external commands. However, main() was not passing the autocorrected command through handle_alias(), hence it failed if it was an 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'".
