Eric Sunshine	e654eb29ab	utf8: NO_ICONV: silence uninitialized variable warning The last argument of reencode_string_len() is an 'int ' which is assigned the length of the converted string. When NO_ICONV is defined, however, reencode_string_len() is stubbed out by the macro: #define reencode_string_len(a,b,c,d,e) NULL which never assigns a value to the final argument. When called like this: int n; char s = reencode_string_len(..., &n); if (s) do_something(s, n); some compilers complain that 'n' is used uninitialized within the conditional.

Junio C Hamano	dde843e737	utf8-bom: introduce skip_utf8_bom() helper With the recent change to ignore the UTF8 BOM at the beginning of .gitignore files, we now have two codepaths that do such a skipping (the other one is for reading the configuration files). Introduce utf8_bom[] constant string and skip_utf8_bom() helper and teach .gitignore code how to use it. Signed-off-by: Junio C Hamano <gitster@pobox.com>	10 years ago
Jeff King	6162a1d323	utf8: add is_hfs_dotgit() helper We do not allow paths with a ".git" component to be added to the index, as that would mean repository contents could overwrite our repository files. However, asking "is this path the same as .git" is not as simple as strcmp() on some filesystems. HFS+'s case-folding does more than just fold uppercase into lowercase (which we already handle with strcasecmp). It may also skip past certain "ignored" Unicode code points, so that (for example) ".gi\u200ct" is mapped ot ".git". The full list of folds can be found in the tables at: https://www.opensource.apple.com/source/xnu/xnu-1504.15.3/bsd/hfs/hfscommon/Unicode/UCStringCompareData.h Implementing a full "is this path the same as that path" comparison would require us importing the whole set of tables. However, what we want to do is much simpler: we only care about checking ".git". We know that 'G' is the only thing that folds to 'g', and so on, so we really only need to deal with the set of ignored code points, which is much smaller.

Jeff King	4621085b7e	add missing "format" function attributes For most of our functions that take printf-like formats, we use gcc's __attribute__((format)) to get compiler warnings when the functions are misused. Let's give a few more functions the same protection. In most cases, the annotations do not uncover any actual bugs; the only code change needed is that we passed a size_t to transfer_debug, which expected an int. Since we expect the passed-in value to be a relatively small buffer size (and cast a similar value to int directly below), we can just cast away the problem.

Nguyễn Thái Ngọc Duy	1640632b4f	pretty: support %>> that steal trailing spaces This is pretty useful in `%<(100)%s%Cred%>(20)% an' where %s does not use up all 100 columns and %an needs more than 20 columns. By replacing %>(20) with %>>(20), %an can steal spaces from %s. %>> understands escape sequences, so %Cred does not stop it from stealing spaces in %<(100).

Kirill Smelkov	6cd3c05327	format-patch: RFC 2047 says multi-octet character may not be split Even though an earlier attempt (bafc478..41dd00bad) cleaned up RFC 2047 encoding, pretty.c::add_rfc2047() still decides where to split the output line by going through the input one byte at a time, and potentially splits a character in the middle. A subject line may end up showing like this: ".... fö?? bar". (instead of ".... föö bar".) if split incorrectly. RFC 2047, section 5 (3) explicitly forbids such beaviour Each 'encoded-word' MUST represent an integral number of characters. A multi-octet character may not be split across adjacent 'encoded- word's. that means that e.g. for Subject: .... föö bar encoding Subject: =?UTF-8?q?....=20f=C3=B6=C3=B6?= =?UTF-8?q?=20bar?= is correct, and Subject: =?UTF-8?q?....=20f=C3=B6=C3?= <-- NOTE ö is broken here =?UTF-8?q?=B6=20bar?= is not, because "ö" character UTF-8 encoding C3 B6 is split here across adjacent encoded words. To fix the problem, make the loop grab one _character_ at a time and determine its output length to see where to break the output line. Note that this version only knows about UTF-8, but the logic to grab one character is abstracted out in mbs_chrlen() function to make it possible to extend it to other encodings with the help of iconv in the future.

Jiang Xin	c082196575	Add utf8_fprintf helper that returns correct number of columns Since command usages can be translated, they may include utf-8 encoded strings, and the output in console may not align well any more. This is because strlen() is different from strwidth() on utf-8 strings. A wrapper utf8_fprintf() can help to return the correct number of columns required.

Junio C Hamano	0e18bcd5e9	reencode_string(): introduce and use same_encoding() Callers of reencode_string() that re-encodes a string from one encoding to another all used ad-hoc way to bypass the case where the input and the output encodings are the same. Some did strcmp(), some did strcasecmp(), yet some others when converting to UTF-8 used is_encoding_utf8(). Introduce same_encoding() helper function to make these callers use the same logic. Notably, is_encoding_utf8() has a work-around for common misconfiguration to use "utf8" to name UTF-8 encoding, which does not match "UTF-8" hence strcasecmp() would not consider the same. Make use of it in this helper function. Signed-off-by: Junio C Hamano <gitster@pobox.com>	12 years ago
Torsten Bögershausen	76759c7dff	git on Mac OS and precomposed unicode Mac OS X mangles file names containing unicode on file systems HFS+, VFAT or SAMBA. When a file using unicode code points outside ASCII is created on a HFS+ drive, the file name is converted into decomposed unicode and written to disk. No conversion is done if the file name is already decomposed unicode. Calling open("\xc3\x84", ...) with a precomposed "Ä" yields the same result as open("\x41\xcc\x88",...) with a decomposed "Ä". As a consequence, readdir() returns the file names in decomposed unicode, even if the user expects precomposed unicode. Unlike on HFS+, Mac OS X stores files on a VFAT drive (e.g. an USB drive) in precomposed unicode, but readdir() still returns file names in decomposed unicode. When a git repository is stored on a network share using SAMBA, file names are send over the wire and written to disk on the remote system in precomposed unicode, but Mac OS X readdir() returns decomposed unicode to be compatible with its behaviour on HFS+ and VFAT. The unicode decomposition causes many problems: - The names "git add" and other commands get from the end user may often be precomposed form (the decomposed form is not easily input from the keyboard), but when the commands read from the filesystem to see what it is going to update the index with already is on the filesystem, readdir() will give decomposed form, which is different. - Similarly "git log", "git mv" and all other commands that need to compare pathnames found on the command line (often but not always precomposed form; a command line input resulting from globbing may be in decomposed) with pathnames found in the tree objects (should be precomposed form to be compatible with other systems and for consistency in general). - The same for names stored in the index, which should be precomposed, that may need to be compared with the names read from readdir(). NFS mounted from Linux is fully transparent and does not suffer from the above. As Mac OS X treats precomposed and decomposed file names as equal, we can - wrap readdir() on Mac OS X to return the precomposed form, and - normalize decomposed form given from the command line also to the precomposed form, to ensure that all pathnames used in Git are always in the precomposed form. This behaviour can be requested by setting "core.precomposedunicode" configuration variable to true. The code in compat/precomposed_utf8.c implements basically 4 new functions: precomposed_utf8_opendir(), precomposed_utf8_readdir(), precomposed_utf8_closedir() and precompose_argv(). The first three are to wrap opendir(3), readdir(3), and closedir(3) functions. The argv[] conversion allows to use the TAB filename completion done by the shell on command line. It tolerates other tools which use readdir() to feed decomposed file names into git. When creating a new git repository with "git init" or "git clone", "core.precomposedunicode" will be set "false". The user needs to activate this feature manually. She typically sets core.precomposedunicode to "true" on HFS and VFAT, or file systems mounted via SAMBA.

Jeff King	98acc837a1	strbuf: add fixed-length version of add_wrapped_text The function strbuf_add_wrapped_text takes a NUL-terminated string. This makes it annoying to wrap strings we have as a pointer and a length. Refactoring strbuf_add_wrapped_text and all of its sub-functions to handle fixed-length strings turned out to be really ugly. So this implementation is lame; it just strdups the text and operates on the NUL-terminated version. This should be fine as the strings we are wrapping are generally pretty short. If it becomes a problem, we can optimize later. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	14 years ago
