* quote: add "sq_dequote_to_argv" to put unwrapped args in an argv arrayChristian Couder2009-03-301-0/+1
| | | | | | | | | This new function unwraps the space separated shell quoted elements in its first argument and places them in the argv array passed as its second argument. Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* quote: implement "sq_dequote_many" to unwrap many args in one stringChristian Couder2009-03-301-0/+8
| | | | | | | | | | | The sq_dequote() function does not allow parsing a string with more than one single-quoted parameter easily; use its code to implement a new API sq_dequote_step() to allow the caller iterate through such a string to parse them one-by-one. The original sq_dequote() becomes a thin wrapper around it. Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* Make private quote_path() in wt-status.c available as quote_path_relative()Dmitry Potapov2008-03-071-0/+4
| | | | | | | | | | | | Move quote_path() from wt-status.c to quote.c and rename it as quote_path_relative(), because it is a better name for a public function. Also, instead of handcrafted quoting, quote_c_style_counted() is now used, to make its quoting more consistent with the rest of the system, also honoring core.quotepath specified in configuration.

* Fix rewrite_diff() name quoting.Junio C Hamano2007-12-261-0/+1
| | | | | | | | | This moves the logic to quote two paths (prefix + path) in C-style introduced in the previous commit from the dump_quoted_path() in combine-diff.c to quote.c, and uses it to fix rewrite_diff() that never C-quoted the pathnames correctly.

* Trace and quote with argv: get rid of unneeded count argument.Christian Couder2007-12-031-2/+1
| | | | | | | | | | | | | Now that str_buf takes care of all the allocations, there is no more gain to pass an argument count. So this patch removes the "count" argument from: - "sq_quote_argv" - "trace_argv_printf" and all the callers.

* sq_quote_argv and add_to_string rework with strbuf's.Pierre Habouzit2007-09-211-6/+3
| | | | | | | | | | * sq_quote_buf is made public, and works on a strbuf. * sq_quote_argv also works on a strbuf. * make sq_quote_argv take a "maxlen" argument to check the buffer won't grow too big.

* Full rework of quote_c_style and write_name_quoted.Pierre Habouzit2007-09-201-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | * quote_c_style works on a strbuf instead of a wild buffer. * quote_c_style is now clever enough to not add double quotes if not needed. * write_name_quoted inherits those advantages, but also take a different set of arguments. Now instead of asking for quotes or not, you pass a "terminator". If it's \0 then we assume you don't want to escape, else C escaping is performed. In any case, the terminator is also appended to the stream. It also no longer takes the prefix/prefix_len arguments, as it's seldomly used, and makes some optimizations harder. * write_name_quotedpfx is created to work like write_name_quoted and take the prefix/prefix_len arguments. Thanks to those API changes, diff.c has somehow lost weight, thanks to the removal of functions that were wrappers around the old write_name_quoted trying to give it a semantics like the new one, but performing a lot of allocations for this goal. Now we always write directly to the stream, no intermediate allocation is performed. As a side effect of the refactor in builtin-apply.c, the length of the bar graphs in diffstats are not affected anymore by the fact that the path was clipped.

* Rework unquote_c_style to work on a strbuf.Pierre Habouzit2007-09-201-1/+1
| | | | | | | | | | | | | | If the gain is not obvious in the diffstat, the resulting code is more readable, _and_ in checkout-index/update-index we now reuse the same buffer to unquote strings instead of always freeing/mallocing. This also is more coherent with the next patch that reworks quoting functions. The quoting function is also made more efficient scanning for backslashes and treating portions of strings without a backslash at once. Signed-off-by: Pierre Habouzit <madcoder@debian.org>

* Teach for-each-ref about a little language called Tcl.Shawn O. Pearce2007-01-281-0/+1
| | | | | | | | | | | | | | Love it or hate it, some people actually still program in Tcl. Some of those programs are meant for interfacing with Git. Programs such as gitk and git-gui. It may be useful to have Tcl-safe output available from for-each-ref, just like shell, Perl and Python already enjoy. Thanks to Sergey Vlasov for pointing out the horrible flaws in the first and second version of this patch, and steering me in the right direction for Tcl value quoting. Signed-off-by: Shawn O.

* Add git-for-each-ref: helper for language bindingsJunio C Hamano2006-09-161-0/+4
| | | | | | | | This adds a new command, git-for-each-ref. You can have it iterate over refs and have it output various aspects of the objects they refer to. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Move add_to_string to "quote.c" and make it extern.Christian Couder2006-09-101-0/+6

* Trace into open fd and refactor tracing code.Christian Couder2006-08-311-0/+1
| | | | | | | | | | | | | | | | | | Now if GIT_TRACE is set to an integer value greater than 1 and lower than 10, we interpret this as an open fd value and we trace into it. Note that this behavior is not compatible with the previous one. We also trace whole messages using one write(2) call to make sure messages from processes do net get mixed up in the middle. It's now possible to run the tests like this: GIT_TRACE=9 make test 9>/var/tmp/trace.log Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

| | | | | | | | | | | | | 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.

* Functions to quote and unquote pathnames in C-style.Junio C Hamano2005-10-171-2/+10
| | | | | | | | | | | | | | Following the list discussion, define two functions, quote_c_style and unquote_c_style, to help adopting the proposed way for quoting funny pathname letters for GNU patch. The rule is described in: http://marc.theaimsgroup.com/?l=git&m=112927316408690&w=2 Currently we do not support the leading '!', but we probably should barf upon seeing it. Rule B4. is interpreted to require always 3 octal digits in \XYZ notation. Signed-off-by: Junio C Hamano <junkio@cox.net>
