* | | grep: Add --max-depth option.Michał Kiedrowicz2009-07-22
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is useful to grep directories non-recursively, e.g. when one wants to look for all files in the toplevel directory, but not in any subdirectory, or in Documentation/, but not in Documentation/technical/. This patch adds support for --max-depth <depth> option to git-grep. If it is given, git-grep descends at most <depth> levels of directories below paths specified on the command line. Note that if path specified on command line contains wildcards, this option makes no sense, e.g. $ git grep -l --max-depth 0 GNU -- 'contrib/*' (note the quotes) will search all files in contrib/, even in subdirectories, because '*' matches all files. Documentation updates, bash-completion and simple test cases are also provided. Signed-off-by: Michał Kiedrowicz <michal.kiedrowicz@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

* grep: prefer builtin over external one when coloring resultsNguyễn Thái Ngọc Duy2009-03-17

* grep: add support for coloring with external grepsRené Scharfe2009-03-07
| | | | | | | | | | | | | | | | | | Add the config variable color.grep.external, which can be used to switch on coloring of external greps. To enable auto coloring with GNU grep, one needs to set color.grep.external to --color=always to defeat the pager started by git grep. The value of the config variable will be passed to the external grep only if it would colorize internal grep's output, so automatic terminal detected works. The default is to not pass any option, because the external grep command could be a program without color support. Also set the environment variables GREP_COLOR and GREP_COLORS to pass the configured color for matches to the external grep. This works with GNU grep; other variables could be added as needed.

* Make on-disk index representation separate from in-core oneLinus Torvalds2008-01-21
| | | | | | | | | | | | | | | | This converts the index explicitly on read and write to its on-disk format, allowing the in-core format to contain more flags, and be simpler. In particular, the in-core format is now host-endian (as opposed to the on-disk one that is network endian in order to be able to be shared across machines) and as a result we can dispense with all the htonl/ntohl on accesses to the cache_entry fields. This will make it easier to make use of various temporary flags that do not exist in the on-disk format. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* grep -An -Bm: fix invocation of external grep commandJunio C Hamano2007-11-17
| | | | | | | | | | When building command line to invoke external grep, the arguments to -A/-B/-C options were placd in randarg[] buffer, but the code forgot that snprintf() does not count terminating NUL in its return value.

* Split grep arguments in a way that does not requires to add /dev/null.Junio C Hamano2007-09-14
| | | | | | | | | | | | | | | | | | | | | | | | In order to (almost) always show the name of the file without relying on "-H" option of GNU grep, we used to add /dev/null to the argument list unless we are doing -l or -L. This caused "/dev/null:0" to show up when -c is given in the output. It is not enough to add -c to the set of options we do not pass /dev/null for. When we have too many files, we invoke grep multiple times and we need to avoid giving a widow filename to the last invocation -- otherwise we will not see the name. This keeps two filenames when the argv[] buffer is about to overflow and we have not finished iterating over the index, so that the last round will always have at least two paths to work with (and not require /dev/null). An obvious and the only exception is when there is only 1 file that is given to the underlying grep, and in that case we avoid passing /dev/null and let the external "grep -c" report only the number of matches.

* git-grep: don't use sscanfJim Meyering2007-03-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you use scanf or sscanf to parse integers, your code probably accepts bogus inputs. For example, builtin-grep (aka git-grep) uses sscanf(scan, "%u", &num) to parse the integer argument to -A, -B, -C. Currently, "-C 1,000" and "-C 4294967297" are both treated just like "-C 1": $ git-grep -h -C 4294967297 juggle out and you may find it easier to switch back and forth if you juggle multiple lines of development simultaneously. Of course, you will pay the price of more disk usage to hold The obvious fix is to use strtoul instead. But using a bare strtoul is too messy, at least when done properly, so I've added a wrapper function. The new function in the patch below belongs elsewhere if it would be useful in replacing any of the four remaining uses of sscanf. One final note: With this change, I get a slightly different diagnostic depending on the context size: $ ./git-grep -h -C 4294967296 juggle fatal: 4294967296: invalid context length argument [Exit 128] $ ./git-grep -h -C 4294967295 juggle grep: 4294967295: invalid context length argument [Exit 1] A common convention that makes it easy to identify the source of a diagnostic is to include the program name before the first ":". Whether that should be "git" or "git-grep" is another question. Using "grep" or "fatal" is misleading. Signed-off-by: Jim Meyering <jim@meyering.net> Signed-off-by: Junio C Hamano <junkio@cox.net>
* Cast 64 bit off_t to 32 bit size_tShawn O. Pearce2007-03-07
| | | | | | | | | | | | | | | | | | Some systems have sizeof(off_t) == 8 while sizeof(size_t) == 4. This implies that we are able to access and work on files whose maximum length is around 2^63-1 bytes, but we can only malloc or mmap somewhat less than 2^32-1 bytes of memory. On such a system an implicit conversion of off_t to size_t can cause the size_t to wrap, resulting in unexpected and exciting behavior. Right now we are working around all gcc warnings generated by the -Wshorten-64-to-32 option by passing the off_t through xsize_t(). In the future we should make xsize_t on such problematic platforms detect the wrapping and die if such a file is accessed. Signed-off-by: Shawn O.

* short i/o: fix calls to read to use xread or read_in_fullAndy Whitcroft2007-01-08
| | | | | | | | | | | We have a number of badly checked read() calls. Often we are expecting read() to read exactly the size we requested or fail, this fails to handle interrupts or short reads. Add a read_in_full() providing those semantics. Otherwise we at a minimum need to check for EINTR and EAGAIN, where this is appropriate use xread().
