* Fix invalid read in quote_c_style_countedJeff King2010-02-061-1/+3
| | | | | | | | | | | | | | | | This function did not work on strings that were not NUL-terminated. It reads through a length-bounded string, searching for characters in need of quoting. After we find one, we output the quoted character, then advance our pointer to find the next one. However, we never decremented the length, meaning we ended up looking at whatever random junk was stored after the string. This bug was not found by the existing tests because most code paths feed a NUL-terminated string. The notable exception is a directory name being fed by ls-tree.

* Fix various sparse warnings in the git source codeLinus Torvalds2009-06-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a few remaining ones, but this fixes the trivial ones. It boils down to two main issues that sparse complains about: - warning: Using plain integer as NULL pointer Sparse doesn't like you using '0' instead of 'NULL'. For various good reasons, not the least of which is just the visual confusion. A NULL pointer is not an integer, and that whole "0 works as NULL" is a historical accident and not very pretty. A few of these remain: zlib is a total mess, and Z_NULL is just a 0. I didn't touch those. - warning: symbol 'xyz' was not declared. Should it be static? Sparse wants to see declarations for any functions you export. A lack of a declaration tends to mean that you should either add one, or you should mark the function 'static' to show that it's in file scope. A few of these remain: I only did the ones that should obviously just be made static. That 'wt_status_submodule_summary' one is debatable. It has a few related flags (like 'wt_status_use_color') which _are_ declared, and are used by builtin-commit.c. So maybe we'd like to export it at some point, but it's not declared now, and not used outside of that file, so 'static' it is in this patch.

* quote: add "sq_dequote_to_argv" to put unwrapped args in an argv arrayChristian Couder2009-03-301-0/+17

* quote: implement "sq_dequote_many" to unwrap many args in one stringChristian Couder2009-03-301-2/+16
| | | | | | | | | | | 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>
* shrink git-shell by avoiding redundant dependenciesDmitry Potapov2008-06-271-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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>

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

* | unquote_c_style: fix off-by-one.Pierre Habouzit2008-03-071-1/+1
|/ | | | | | | | | | | | | | | | | | The optional endp parameter to unquote_c_style() was supposed to point at a location past the closing double quote, but it was going one beyond it. git-fast-import used this function heavily and the bug caused it to misparse the input stream, especially when parsing a rename command: R "filename that needs quoting" rename-target-name Because the function erroneously ate the whitespace after the closing dq, this triggered "Missing space after source" error when it shouldn't.

* Fix rewrite_diff() name quoting.Junio C Hamano2007-12-261-0/+16
| | | | | | | | | 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 Couder2007-12-031-10/+3

* strbuf change: be sure ->buf is never ever NULL.Pierre Habouzit2007-09-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | For that purpose, the ->buf is always initialized with a char * buf living in the strbuf module. It is made a char * so that we can sloppily accept things that perform: sb->buf[0] = '\0', and because you can't pass "" as an initializer for ->buf without making gcc unhappy for very good reasons. strbuf_init/_detach/_grow have been fixed to trust ->alloc and not ->buf anymore. as a consequence strbuf_detach is _mandatory_ to detach a buffer, copying ->buf isn't an option anymore, if ->buf is going to escape from the scope, and eventually be free'd. API changes: * strbuf_setlen now always works, so just make strbuf_reset a convenience macro. * strbuf_detatch takes a size_t* optional argument (meaning it can be NULL) to copy the buffer's len, as it was needed for this refactor to make the code more readable, and working like the callers.

* Full rework of quote_c_style and write_name_quoted.Pierre Habouzit2007-09-201-90/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | * 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 Habouzit2007-09-201-53/+51
| | | | | | | | | | | | | | 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>
* Add core.quotepath configuration variable.Junio C Hamano2007-06-241-2/+3
| | | | | | | | | | | | | | | | | | | | | | | We always quote "unusual" byte values in a pathname using C-string style, to make it safer for parsing scripts that do not handle NUL separated records well (or just too lazy to bother). The absolute minimum bytes that need to be quoted for this purpose are TAB, LF (and other control characters), double quote and backslash. However, we have also always quoted the bytes in high 8-bit range; this was partly because we were lazy and partly because we were being cautious. This introduces an internal "quote_path_fully" variable, and core.quotepath configuration variable to control it. When set to false, it does not quote bytes in high 8-bit range anymore but passes them intact. The variable defaults to "true" to retain the traditional behaviour for now.
