* trace: avoid unnecessary quotingJeff King2018-01-161-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | Trace output which contains arbitrary strings (e.g., the arguments to commands which we are running) is always passed through sq_quote_buf(). That function always adds single-quotes, even if the output consists of vanilla characters. This can make the output a bit hard to read. Let's avoid the quoting if there are no characters which a shell would interpret. Trace output doesn't necessarily need to be shell-compatible, but: - the shell language is a good ballpark for what humans consider readable (well, humans versed in command line tools) - the run_command bits can be cut-and-pasted to a shell, and we'll keep that property - it covers any cases which would make the output visually ambiguous (e.g., embedded whitespace or quotes) Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* sq_quote_argv: drop maxlen parameterJeff King2018-01-161-1/+1
| | | | | | | | | | | | No caller passes anything but "0" for this parameter, which requests that the function ignore it completely. In fact, in all of history there was only one such caller, and it went away in 7f51f8bc2b (alias: use run_command api to execute aliases, 2011-01-07).

| * grep/icase: avoid kwsset when -F is specifiedNguyễn Thái Ngọc Duy2016-07-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to the previous commit, we can't use kws on icase search outside ascii range. But we can't simply pass the pattern to regcomp/pcre like the previous commit because it may contain regex special characters, so we need to quote the regex first. To avoid misquote traps that could lead to undefined behavior, we always stick to basic regex engine in this case. We don't need fancy features for grepping a literal string anyway. basic_regex_quote_buf() assumes that if the pattern is in a multibyte encoding, ascii chars must be unambiguously encoded as single bytes. This is true at least for UTF-8. For others, let's wait until people yell up. Chances are nobody uses multibyte, non utf-8 charsets anymore.

* ls-tree: remove path filtering logic in show_treeNguyễn Thái Ngọc Duy2014-12-011-2/+0
| | | | | | | | | | | ls-tree uses read_tree_recursive() which already does path filtering using pathspec. No need to filter one more time based on prefix only. "ls-tree ../somewhere" does not work because of this. write_name_quotedpfx() can now be retired because nobody else uses it.

* write_name{_quoted_relative,}(): remove redundant parametersJiang Xin2013-06-261-2/+1
| | | | | | | | | | | | | | After substitute path_relative() in quote.c with relative_path() from path.c, parameters (such as len and prefix_len) are redundant in function write_name() and write_name_quoted_relative(). The callers have already been audited that the strings they pass are properly NUL terminated and the length they give are the length of the string (or -1 that asks the length to be counted by the callee). Remove these now-redundant parameters. Signed-off-by: Jiang Xin <worldhello.net@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* quote_path_relative(): remove redundant parameterJiang Xin2013-06-261-2/+2
| | | | | | | | | | | | | | | | | | | | quote_path_relative() used to take a counted string as its parameter (the string to be quoted). With an earlier change, it now uses relative_path() that does not take a counted string, and we have been passing only the pointer to the string since then. Remove the length parameter from quote_path_relative() to show that this parameter was redundant. All the changed lines show that the caller passed either -1 (to ask the function run strlen() on the string), or the length of the string, so the earlier conversion was safe. All the callers of quote_path_relative() that used to take counted string have been audited to make sure that they are passing length of the actual string (or -1 to ask the callee run strlen()) Signed-off-by: Jiang Xin <worldhello.net@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* quote: provide sq_dequote_to_argv_arrayJeff King2011-09-141-0/+8
| | | | | | | | | | | | | | | | | This is similar to sq_dequote_to_argv, but more convenient if you have an argv_array. It's tempting to just feed the components of the argv_array to sq_dequote_to_argv instead, but: 1. It wouldn't maintain the NULL-termination invariant of argv_array. 2. It doesn't match the memory ownership policy of argv_array (in which each component is free-able, not a pointer into a separate buffer).

| | | | | | | | | | | Commit 758e915 made sq_quote_next static, removing it from quote.h.

* 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>
