Ramkumar Ramachandra	70256a3a67	shell: Rewrite documentation and improve error message Update the documentation of 'git shell' to mention the interactive mode and COMMAND_DIR. Also provide a hint when interactive mode is not available in the shell.

Greg Brockman	2dbc887eaa	Allow creation of arbitrary git-shell commands This provides a mechanism for the server to expose custom functionality to clients. My particular use case is that I would like a way of discovering all repositories available for cloning. A client that clones via git clone user@example.com can invoke a command by ssh user@example.com $command Signed-off-by: Greg Brockman <gdb@mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>	15 years ago
Thomas Rast	d824cbba02	Convert existing die(..., strerror(errno)) to die_errno() Change calls to die(..., strerror(errno)) to use the new die_errno(). In the process, also make slight style adjustments: at least state _something_ about the function that failed (instead of just printing the pathname), and put paths in single quotes.

Junio C Hamano	6ffaecc7d8	shell: do not play duplicated definition games to shrink the executable Playing with linker games to shrink git-shell did not go well with various other platforms and compilers. Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
Paolo Bonzini	0cfeed2e1d	make git-shell paranoid about closed stdin/stdout/stderr It is in general unsafe to start a program with one or more of file descriptors 0/1/2 closed. Karl Chen for example noticed that stat_command does this in order to rename a pipe file descriptor to 0: dup2(from, 0); close(from); ... but if stdin was closed (for example) from == 0, so that dup2(0, 0); close(0); just ends up closing the pipe. Another extremely rare but nasty problem would occur if an "important" file ends up in file descriptor 2, and is corrupted by a call to die(). Fixing this in git was considered to be overkill, so this patch works around it only for git-shell. The fix is simply to open all the "low" descriptors to /dev/null in main.

Junio C Hamano	1e7abc593d	Revert "Build-in "git-shell"" This reverts commit `daa0cc9a92`. It was a stupid idea to do this; when run as a log-in shell, it is spawned with argv[0] set to "-git-shell", so the usual name-based dispatch would not work to begin with.	17 years ago
Junio C Hamano	daa0cc9a92	Build-in "git-shell" This trivially makes "git-shell" a built-in. It makes the executable even fatter, though. And MinGW removed git-shell only because of the funny dependencies; there is no reason to do so anymore.

Johannes Sixt	e1464ca7bb	Record the command invocation path early We will need the command invocation path in system_path(). This path was passed to setup_path(), but system_path() can be called earlier, for example via: main commit_pager_choice setup_pager git_config git_etc_gitconfig system_path Therefore, we introduce git_set_argv0_path() and call it as soon as possible.

Dmitry Potapov	5b8e6f85f9	shrink git-shell by avoiding redundant dependencies A lot of modules that have nothing to do with git-shell functionality were linked in, bloating git-shell more than 8 times. This patch cuts off redundant dependencies by: 1. providing stubs for three functions that make no sense for git-shell; 2. moving quote_path_fully from environment.c to quote.c to make the later self sufficient; 3. moving make_absolute_path into a new separate file. The following numbers have been received with the default optimization settings on master using GCC 4.1.2: Before: text data bss dec hex filename 143915 1348 93168 238431 3a35f git-shell After: text data bss dec hex filename 17670 788 8232 26690 6842 git-shell Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago

Johannes Schindelin	0c696fe7f4	Support cvs via git-shell This adds cvs support to the git-shell; You can now give new users a restricted git-shell and they still can commit via git's cvs emulator. Note that either the gecos information must be accurate, or you must provide a $HOME/.gitconfig with the appropriate user credentials. Since the git-shell is too restricted to allow the user to do it (on purpose!), it is up to the administrator to take care of that. Based on an idea by Jan Wielemaker.

Junio C Hamano	cc44c7655f	Mechanical conversion to use prefixcmp() 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 Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Junio C Hamano	9201c70742	Const tightening. Mark Wooding noticed there was a type mismatch warning in git.c; this patch does things slightly differently (mostly tightening const) and was what I was holding onto, waiting for the setup-revisions change to be merged into the master branch.

Michal Ostrowski	77cb17e940	Exec git programs without using PATH. The git suite may not be in PATH (and thus programs such as git-send-pack could not exec git-rev-list). Thus there is a need for logic that will locate these programs. Modifying PATH is not desirable as it result in behavior differing from the user's intentions, as we may end up prepending "/usr/bin" to PATH. - git C programs will use exec_git_cmd() APIs to exec sub-commands. - exec_git_cmd() will execute a git program by searching for it in the following directories: 1. --exec-path (as used by "git") 2. The GIT_EXEC_PATH environment variable. 3. $(gitexecdir) as set in Makefile (default value $(bindir)). - git wrapper will modify PATH as before to enable shell scripts to invoke "git-foo" commands. Ideally, shell scripts should use the git wrapper to become independent of PATH, and then modifying PATH will not be necessary.

Linus Torvalds	35eb2d3641	Add git-shell. This adds a very git specific restricted shell, that can be added to /etc/shells and set to the pw_shell in the /etc/passwd file, to give users ability to push into repositories over ssh without giving them full interactive shell acount.
