2017-09-22consistently use "fallthrough" comments in switchesLibravatar Jeff King1-0/+1
Gcc 7 adds -Wimplicit-fallthrough, which can warn when a switch case falls through to the next case. The general idea is that the compiler can't tell if this was intentional or not, so you should annotate any intentional fall-throughs as such, leaving it to complain about any unannotated ones. There's a GNU __attribute__ which can be used for annotation, but of course we'd have to #ifdef it away on non-gcc compilers. Gcc will also recognize specially-formatted comments, which matches our current practice. Let's extend that practice to all of the unannotated sites (which I did look over and verify that they were behaving as intended). Ideally in each case we'd actually give some reasons in the comment about why we're falling through, or what we're falling through to. And gcc does support that with -Wimplicit-fallthrough=2, which relaxes the comment pattern matching to anything that contains "fallthrough" (or a variety of spelling variants). However, this isn't the default for -Wimplicit-fallthrough, nor for -Wextra. In the name of simplicity, it's probably better for us to support the default level, which requires "fallthrough" to be the only thing in the comment (modulo some window dressing like "else" and some punctuation; see the gcc manual for the complete set of patterns). This patch suppresses all warnings due to -Wimplicit-fallthrough. We might eventually want to add that to the DEVELOPER Makefile knob, but we should probably wait until gcc 7 is more widely adopted (since earlier versions will complain about the unknown warning type).

2016-07-01grep/icase: avoid kwsset when -F is specifiedLibravatar Nguyễn Thái Ngọc Duy1-0/+37
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.

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().

2013-06-26quote_path_relative(): remove redundant parameterLibravatar Jiang Xin1-5/+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>
2013-06-26quote.c: substitute path_relative with relative_pathLibravatar Jiang Xin1-53/+2
Substitute the function path_relative in quote.c with the function relative_path. Function relative_path can be treated as an enhanced and more robust version of path_relative. Outputs of path_relative and it's replacement (relative_path) are the same for the following cases: path prefix output of path_relative output of relative_path ======== ========= ======================= ======================= /a/b/c/ /a/b/ c/ c/ /a/b/c /a/b/ c c /a/ /a/b/ ../ ../ / /a/b/ ../../ ../../ /a/c /a/b/ ../c ../c /x/y /a/b/ ../../x/y ../../x/y a/b/c/ a/b/ c/ c/ a/ a/b/ ../ ../ x/y a/b/ ../../x/y ../../x/y /a/b (empty) /a/b /a/b /a/b (null) /a/b /a/b a/b (empty) a/b a/b a/b (null) a/b a/b But if both of the path and the prefix are the same, or the returned relative path should be the current directory, the outputs of both functions are different. Function relative_path returns "./", while function path_relative returns empty string. path prefix output of path_relative output of relative_path ======== ========= ======================= ======================= /a/b/ /a/b/ (empty) ./ a/b/ a/b/ (empty) ./ (empty) (null) (empty) ./ (empty) (empty) (empty) ./ But the callers of path_relative can handle such cases, or never encounter this issue at all, because: * In function quote_path_relative, if the output of path_relative is empty, append "./" to it, like: if (!out->len) strbuf_addstr(out, "./"); * Another caller is write_name_quoted_relative, which is only used by builtin/ls-files.c. git-ls-files only show files, so path of files will never be identical with the prefix of a directory. The following differences show that path_relative does not handle extra slashes properly: path prefix output of path_relative output of relative_path ======== ========= ======================= ======================= /a//b//c/ //a/b// ../../../../a//b//c/ c/ a/b//c a//b ../b//c c And if prefix has no trailing slash, path_relative does not work properly either. But since prefix always has a trailing slash, it's not a problem. path prefix output of path_relative output of relative_path ======== ========= ======================= ======================= /a/b/c/ /a/b b/c/ c/ /a/b /a/b b ./ /a/b/ /a/b b/ ./ /a /a/b/ ../../a ../ a/b/c/ a/b b/c/ c/ a/b/ a/b b/ ./ a a/b ../a ../ x/y a/b/ ../x/y ../../x/y a/c a/b c ../c /a/ /a/b (empty) ../ (empty) /a/b ../../ ./ One tricky part in this conversion is write_name() function in ls-files.c. It takes a counted string, <name, len>, that is to be made relative to <prefix, prefix_len> and then quoted. Because write_name_quoted_relative() still takes these two parameters as counted string, but ignores the count and treat these two as NUL-terminated strings, this conversion needs to be audited for its callers: - For <name, len>, all three callers of write_name() passes a NUL-terminated string and its true length, so this patch makes "len" unused. - For <prefix, prefix_len>, prefix could be a string that is longer than empty while prefix_len could be 0 when "--full-name" option is used. This is fixed by checking prefix_len in write_name() and calling write_name_quoted_relative() with NULL when prefix_len is set to 0. Again, this makes "prefix_len" given to write_name_quoted_relative() unused, without introducing a bug.

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.

2011-08-11ls-files: fix pathspec display on errorLibravatar Clemens Buchacher1-2/+6
The following sequence of commands reveals an issue with error reporting of relative paths: $ mkdir sub $ cd sub $ git ls-files --error-unmatch ../bbbbb error: pathspec 'b' did not match any file(s) known to git. $ git commit --error-unmatch ../bbbbb error: pathspec 'b' did not match any file(s) known to git. This bug is visible only if the normalized path (i.e., the relative path from the repository root) is longer than the prefix. Otherwise, the code skips over the normalized path and reads from an unused memory location which still contains a leftover of the original command line argument. So instead, use the existing facilities to deal with relative paths correctly. Also fix inconsistency between "checkout" and "commit", e.g. $ cd Documentation $ git checkout nosuch.txt error: pathspec 'Documentation/nosuch.txt' did not match... $ git commit nosuch.txt error: pathspec 'nosuch.txt' did not match... by propagating the prefix down the codepath that reports the error.

2010-02-06Fix invalid read in quote_c_style_countedLibravatar Jeff King1-1/+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.

2009-06-20Fix various sparse warnings in the git source codeLibravatar Linus Torvalds1-2/+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.

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.

* 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.

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.

2006-04-17cleanups: Remove impossible case in quote.cLibravatar Serge E. Hallyn1-2/+0
The switch is inside an if statement which is false if the character is ' '. Either the if should be <=' ' instead of <' ', or the case should be removed as it could be misleading. Signed-off-by: Serge E. Hallyn <serue@us.ibm.com> Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-12-21[PATCH] quote.c: Make loop control more readable.Libravatar Pavel Roskin1-2/+4
quote_c_style_counted() in quote.c uses a hard-to-read construct. Convert this to a more traditional form of the for loop. Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

2005-10-24Add git-shell.Libravatar Linus Torvalds1-1/+40
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. [jc: I updated Linus' patch to match what the current sq_quote() does.] Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-10-17Do not quote SP.Libravatar Junio C Hamano1-2/+2
Follow the "encode minimally" principle -- our tools, including git-apply and git-status, can handle pathnames with embedded SP just fine. The only problematic ones are TAB and LF, and we need to quote the metacharacters introduced for quoting. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-10-17Functions to quote and unquote pathnames in C-style.Libravatar Junio C Hamano1-0/+165
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>
