When apply_filter() runs the external (clean or smudge) filter program, it needs to pass the writable end of a pipe as its stdout. For this purpose, it used to dup2(2) the file descriptor explicitly to stdout. Now we use the facilities of start_command() to do it for us. Furthermore, the path argument of a subordinate function, filter_buffer(), was not used, so here we replace it to pass the fd instead.

* crlf_to_git and ident_to_git: Don't grow the buffer if there is enough space in the first place. As a side effect, when the editing is done "in place", we don't grow, so the buffer pointer doesn't changes, and `src' isn't invalidated anymore. Thanks to Bernt Hansen for the bug report. * apply_filter: Fix memory leak due to fake in-place editing that didn't collected the old buffer when the filter succeeds. Also a cosmetic fix.

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.

* Now, those functions take an "out" strbuf argument, where they store their result if any. In that case, it also returns 1, else it returns 0. * those functions support "in place" editing, in the sense that it's OK to call them this way: convert_to_git(path, sb->buf, sb->len, sb); When doable, conversions are done in place for real, else the strbuf content is just replaced with the new one, transparentely for the caller. If you want to create a new filter working this way, being the accumulation of filter1, filter2, ... filtern, then your meta_filter would be: int meta_filter(..., const char *src, size_t len, struct strbuf *sb) { int ret = 0; ret |= filter1(...., src, len, sb); if (ret) { src = sb->buf; len = sb->len; } ret |= filter2(...., src, len, sb); if (ret) { src = sb->buf; len = sb->len; } .... return ret | filtern(..., src, len, sb); } That's why subfilters the convert_to_* functions called were also rewritten to work this way.

If the repository contained an expanded ident keyword (i.e. $Id:XXXX$), then the wrong bytes were discarded, and the Id keyword was not expanded. The fault was in convert.c:ident_to_worktree(). Previously, when a "$Id:" was found in the repository version, ident_to_worktree() would search for the next "$" after this, and discarded everything it found until then. That was done with the loop: do { ch = *cp++; if (ch == '$') break; rem--; } while (rem); The above loop left cp pointing one character _after_ the final "$" (because of ch = *cp++). This was different from the non-expanded case, were cp is left pointing at the "$", and was different from the comment which stated "discard up to but not including the closing $". This patch fixes that by making the loop: do { ch = *cp; if (ch == '$') break; cp++; rem--; } while (rem); That is, cp is tested _then_ incremented. This loop exits if it finds a "$" or if it runs out of bytes in the source. After this loop, if there was no closing "$" the expansion is skipped, and the outer loop is allowed to continue leaving this non-keyword as it was. However, when the "$" is found, size is corrected, before running the expansion: size -= (cp - src); This is wrong; size is going to be corrected anyway after the expansion, so there is no need to do it here. This patch removes that redundant correction. To help find this bug, I heavily commented the routine; those comments are included here as a bonus.

gitattributes.txt says, of the crlf attribute: Set:: Setting the `crlf` attribute on a path is meant to mark the path as a "text" file. 'core.autocrlf' conversion takes place without guessing the content type by inspection. That is to say that the crlf attribute does not force the file to have CRLF line endings, instead it removes the autocrlf guesswork and forces the file to be treated as text. Then, whatever line ending is defined by the autocrlf setting is applied. However, that is not what convert.c was doing. The conversion to CRLF was being skipped in crlf_to_worktree() when the following condition was true: action == CRLF_GUESS && auto_crlf <= 0 That is to say conversion took place when not in guess mode (crlf attribute not specified) or core.autocrlf set to true. This was wrong. It meant that the crlf attribute being on for a given file _forced_ CRLF conversion, when actually it should force the file to be treated as text, and converted accordingly. The real test should simply be auto_crlf <= 0 That is to say, if core.autocrlf is falsei (or input), conversion from LF to CRLF is never done. When core.autocrlf is true, conversion from LF to CRLF is done only when in CRLF_GUESS (and the guess is "text"), or CRLF_TEXT mode. Similarly for crlf_to_worktree(), if core.autocrlf is false, no conversion should _ever_ take place. In reality it was only not taking place if core.autocrlf was false _and_ the crlf attribute was unspecified.

As noted by Johan Herland, git-archive is a kind of checkout and needs to apply any checkout filters that might be configured. This patch adds the convenience function convert_sha1_file which returns a buffer containing the object's contents, after converting, if necessary (i.e. it's a combination of read_sha1_file and convert_to_working_tree). Direct calls to read_sha1_file in git-archive are then replaced by calls to convert_sha1_file. Since convert_sha1_file expects its path argument to be NUL-terminated -- a convention it inherits from convert_to_working_tree -- the patch also changes the path handling in archive-tar.c to always NUL-terminate the string. It used to solely rely on the len field of struct strbuf before. archive-zip.c already NUL-terminates the path and thus needs no such change.

$Id$ is present already in SVN and CVS; it would mean that people converting their existing repositories won't have to make any changes to the source files should they want to make use of the ident attribute. Given that it's a feature that's meant to calm those very people, it seems obtuse to make them edit every file just to make use of it. I think that bzr uses $Id$; Mercurial has examples hooks for $Id$; monotone has $Id$ on its wishlist. I can't think of a good reason not to stick with the de-facto standard and call ours $Id$ instead of $ident$.

The interface is similar to the custom low-level merge drivers. First you configure your filter driver by defining 'filter.<name>.*' variables in the configuration. filter.<name>.clean filter command to run upon checkin filter.<name>.smudge filter command to run upon checkout Then you assign filter attribute to each path, whose name matches the custom filter driver's name. Example: (in .gitattributes) *.c filter=indent (in config) [filter "indent"] clean = indent smudge = cat Signed-off-by: NJunio C Hamano <junkio@cox.net>

The 'ident' attribute set to path squashes "$ident:<any bytes except dollor sign>$" to "$ident$" upon checkin, and expands it to "$ident: <blob SHA-1> $" upon checkout. As we have two conversions that affect checkin/checkout paths, clarify how they interact with each other. Signed-off-by: NJunio C Hamano <junkio@cox.net>

This separates the checkattr() call and interpretation of the returned value specific to the 'crlf' attribute into separate routines, so that we can run a single call to checkattr() to check for more than one attributes, and then interprete what the returned settings mean separately.

This updates the semantics of 'crlf' so that .gitattributes file can say "this is text, even though it may look funny". Setting the `crlf` attribute on a path is meant to mark the path as a "text" file. 'core.autocrlf' conversion takes place without guessing the content type by inspection. Unsetting the `crlf` attribute on a path is meant to mark the path as a "binary" file. The path never goes through line endings conversion upon checkin/checkout. Unspecified `crlf` attribute tells git to apply the `core.autocrlf` conversion when the file content looks like text. Setting the `crlf` attribut to string value "input" is similar to setting the attribute to `true`, but also forces git to act as if `core.autocrlf` is set to `input` for the path.

It was bothering me a lot that I abused small integer values casted to (void *) to represent non string values in gitattributes. This corrects it by making the type of attribute values (const char *), and using the address of a few statically allocated character buffer to denote true/false. Unset attributes are represented as having NULLs as their values. Added in-header documentation to explain how git_checkattr() routine should be called.

This allows you to define three values (and possibly more) to each attribute: true, false, and unset. Typically the handlers that notice and act on attribute values treat "unset" attribute to mean "do your default thing" (e.g. crlf that is unset would trigger "guess from contents"), so being able to override a setting to an unset state is actually useful. - If you want to set the attribute value to true, have an entry in .gitattributes file that mentions the attribute name; e.g. *.o binary - If you want to set the attribute value explicitly to false, use '-'; e.g. *.a -diff - If you want to make the attribute value _unset_, perhaps to override an earlier entry, use '!'; e.g. *.a -diff c.i.a !diff This also allows string values to attributes, with the natural syntax: attrname=attrvalue but you cannot use it, as nobody takes notice and acts on it yet.

Earlier we said 'crlf lets the path go through core.autocrlf process while !crlf disables it altogether'. This fixes the semantics to: - Lack of 'crlf' attribute makes core.autocrlf to apply (i.e. we guess based on the contents and if platform expresses its desire to have CRLF line endings via core.autocrlf, we do so). - Setting 'crlf' attribute to true forces CRLF line endings in working tree files, even if blob does not look like text (e.g. contains NUL or other bytes we consider binary). - Setting 'crlf' attribute to false disables conversion.

This defines the semantics of 'crlf' attribute as an example. When a path has this attribute unset (i.e. '!crlf'), autocrlf line-end conversion is not applied. Eventually we would want to let users to build a pipeline of processing to munge blob data to filesystem format (and in the other direction) based on combination of attributes, and at that point the mechanism in convert_to_{git,working_tree}() that looks at 'crlf' attribute needs to be enhanced. Perhaps the existing 'crlf' would become the first step in the input chain, and the last step in the output chain. Signed-off-by: NJunio C Hamano <junkio@cox.net>

This allows you to do: [core] AutoCRLF = input and it should do only the CRLF->LF translation (ie it simplifies CRLF only when reading working tree files, but when checking out files, it leaves the LF alone, and doesn't turn it into a CRLF).

It currently does NOT know about file attributes, so it does its conversion purely based on content. Maybe that is more in the "git philosophy" anyway, since content is king, but I think we should try to do the file attributes to turn it off on demand. Anyway, BY DEFAULT it is off regardless, because it requires a [core] AutoCRLF = true in your config file to be enabled. We could make that the default for Windows, of course, the same way we do some other things (filemode etc). But you can actually enable it on UNIX, and it will cause: - "git update-index" will write blobs without CRLF - "git diff" will diff working tree files without CRLF - "git checkout" will write files to the working tree _with_ CRLF and things work fine. Funnily, it actually shows an odd file in git itself: git clone -n git test-crlf cd test-crlf git config core.autocrlf true git checkout git diff shows a diff for "Documentation/docbook-xsl.css". Why? Because we have actually checked in that file *with* CRLF! So when "core.autocrlf" is true, we'll always generate a *different* hash for it in the index, because the index hash will be for the content _without_ CRLF. Is this complete? I dunno. It seems to work for me. It doesn't use the filename at all right now, and that's probably a deficiency (we could certainly make the "is_binary()" heuristics also take standard filename heuristics into account). I don't pass in the filename at all for the "index_fd()" case (git-update-index), so that would need to be passed around, but this actually works fine. NOTE NOTE NOTE! The "is_binary()" heuristics are totally made-up by yours truly. I will not guarantee that they work at all reasonable. Caveat emptor. But it _is_ simple, and it _is_ safe, since it's all off by default. The patch is pretty simple - the biggest part is the new "convert.c" file, but even that is really just basic stuff that anybody can write in "Teaching C 101" as a final project for their first class in programming. Not to say that it's bug-free, of course - but at least we're not talking about rocket surgery here.
