* diff: add filter for converting binary to textJeff King2008-10-181-2/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | When diffing binary files, it is sometimes nice to see the differences of a canonical text form rather than either a binary patch or simply "binary files differ." Until now, the only option for doing this was to define an external diff command to perform the diff. This was a lot of work, since the external command needed to take care of doing the diff itself (including mode changes), and lost the benefit of git's colorization and other options. This patch adds a text conversion option, which converts a file to its canonical format before performing the diff. This is less flexible than an arbitrary external diff, but is much less work to set up. For example: $ echo '*.jpg diff=exif' >>.gitattributes $ git config diff.exif.textconv exiftool $ git config diff.exif.binary false allows one to see jpg diffs represented by the text output of exiftool.

* diff: introduce diff.<driver>.binaryJeff King2008-10-181-30/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "diff" gitattribute is somewhat overloaded right now. It can say one of three things: 1. this file is definitely binary, or definitely not (i.e., diff or !diff) 2. this file should use an external diff engine (i.e., diff=foo, diff.foo.command = custom-script) 3. this file should use particular funcname patterns (i.e., diff=foo, diff.foo.(x?)funcname = some-regex) Most of the time, there is no conflict between these uses, since using one implies that the other is irrelevant (e.g., an external diff engine will decide for itself whether the file is binary). However, there is at least one conflicting situation: there is no way to say "use the regular rules to determine whether this file is binary, but if we do diff it textually, use this funcname pattern." That is, currently setting diff=foo indicates that the file is definitely text. This patch introduces a "binary" config option for a diff driver, so that one can explicitly set diff.foo.binary. We default this value to "don't know". That is, setting a diff attribute to "foo" and using "diff.foo.funcname" will have no effect on the binaryness of a file. To get the current behavior, one can set diff.foo.binary to true. This patch also has one additional advantage: it cleans up the interface to the userdiff code a bit. Before, calling code had to know more about whether attributes were false, true, or unset to determine binaryness. Now that binaryness is a property of a driver, we can represent these situations just by passing back a driver struct. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Shawn O.

* diff: unify external diff and funcname parsing codeJeff King2008-10-181-224/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both sets of code assume that one specifies a diff profile as a gitattribute via the "diff=foo" attribute. They then pull information about that profile from the config as diff.foo.*. The code for each is currently completely separate from the other, which has several disadvantages: - there is duplication as we maintain code to create and search the separate lists of external drivers and funcname patterns - it is difficult to add new profile options, since it is unclear where they should go - the code is difficult to follow, as we rely on the "check if this file is binary" code to find the funcname pattern as a side effect. This is the first step in refactoring the binary-checking code. This patch factors out these diff profiles into "userdiff" drivers. A file with "diff=foo" uses the "foo" driver, which is specified by a single struct. Note that one major difference between the two pieces of code is that the funcname patterns are always loaded, whereas external drivers are loaded only for the "git diff" porcelain; the new code takes care to retain that situation.

* Replace calls to strbuf_init(&foo, 0) with STRBUF_INIT initializerBrandon Casey2008-10-121-10/+5
| | | | | | | | | | | Many call sites use strbuf_init(&foo, 0) to initialize local strbuf variable "foo" which has not been accessed since its declaration. These can be replaced with a static initialization using the STRBUF_INIT macro which is just as readable, saves a function call, and takes up fewer lines.

| * fix bogus "diff --git" header from "diff --no-index"Linus Torvalds2008-10-061-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When "git diff --no-index" is given an absolute pathname, it would generate a diff header with the absolute path prepended by the prefix, like: diff --git a/dev/null b/foo Not only is this nonsensical, and not only does it violate the description of diffs given in git-diff(1), but it would produce broken binary diffs. Unlike text diffs, the binary diffs don't contain the filenames anywhere else, and so "git apply" relies on this header to figure out the filename. This patch just refuses to use an invalid name for anything visible in the diff. Now, this fixes the "git diff --no-index --binary a /dev/null" kind of case (and we'll end up using "a" as the basename), but some other insane cases are impossible to handle. If you do git diff --no-index --binary a /bin/echo you'll still get a patch like diff --git a/a b/bin/echo old mode 100644 new mode 100755 index ... and "git apply" will refuse to apply it for a couple of reasons, and the diff is simply bogus. And that, btw, is no longer a bug, I think. It's impossible to know whethe the user meant for the patch to be a rename or not. And as such, refusing to apply it because you don't know what name you should use is probably _exactly_ the right thing to do! Original problem reported by Imre Deak.

Compilation of git is probably broken on PPC too for the same reason. Turns out that the only file requiring openssl/ssl.h and openssl/err.h is imap-send.c. But only moving those problematic includes there doesn't solve the issue as it also includes cache.h which brings in the conflicting local SHA1 header file. As suggested by Jeff King, the best solution is to rename our references to SHA1 functions and structure to something git specific, and define those according to the implementation used.

This however is unwieldy when multiple regexp feature is used to specify alternatives. This fixes the semantics to take the first match. A nagative pattern, if matches, makes the line to fail as before. A match with a positive pattern will be the final match, and what it captures in $1 is used as the hunk header comment. We could write alternatives using "|" in ERE, but the machinery can only use captured $1 as the hunk header comment (or $0 if there is no match in $1), so you cannot write: "junk ( A | B ) | garbage ( C | D )" and expect both "junk" and "garbage" to get stripped with the existing code. With this fix, you can write it as: "junk ( A | B ) \n garbage ( C | D )" and the way capture works would match the user expectation more naturally. Signed-off-by: Junio C Hamano <gitster@pobox.com>

The 'funcname' option takes a basic regular expression. This functionality was designed using the GNU regex library which, by default, allows using backslashed versions of some extended regular expression operators, even in Basic Regular Expression mode. For example, the following characters, when backslashed, are interpreted according to the extended regular expression rules: ?, +, and |. As such, the builtin funcname patterns were created using some extended regular expression operators. Other platforms which adhere more strictly to the POSIX spec do not interpret the backslashed extended RE operators in Basic Regular Expression mode. This causes the pattern matching for the builtin funcname patterns to fail on those platforms. Introduce a new option 'xfuncname' which uses extended regular expressions, and advertise it _instead_ of funcname. Since most users are on GNU platforms, the majority of funcname patterns are created and tested there. Advertising only xfuncname should help to avoid the creation of non-portable patterns which work with GNU regex but not elsewhere. Additionally, the extended regular expressions may be less ugly and complicated compared to the basic RE since many common special operators do not need to be backslashed. For example, the GNU Basic RE: ^[ ]*\\(\\(public\\|static\\).*\\)$ becomes the following Extended RE: ^[ ]*((public|static).*)$ Signed-off-by: Brandon Casey <casey@nrlssc.navy.mil> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Well behaved scripts, when they expect to run many diff operations inside, are supposed to run "update-index --refresh" upfront; we do not want them to pay the price of iterating over the index and comparing the contents to fix the stat dirtiness, and we avoided most of the processing in diffcore_std() when --quiet is in effect. But scripts that adhere to the good practice won't have to pay any more price than the necessary lstat(2) that will report stat cleanliness, as long as only -q is given without any fancier diff options. More importantly, users who do ask for "--quiet -M --filter=D" (in order to notice only the deletion, not paths that disappeared only because they have been renamed away) deserve to get the result they asked for, even it means they have to pay the extra price; the alternative is to get a cheap early return that gives a result they did not ask for, which is much worse.

| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the tracked contents have CRLF line endings, colored diff output shows "^M" at the end of output lines, which is distracting, even though the pager we use by default ("less") knows to hide them. The problem is that "less" hides a carriage-return only at the end of the line, immediately before a line feed. The colored diff output does not take this into account, and emits four element sequence for each line: - force this color; - the line up to but not including the terminating line feed; - reset color - line feed. By including the carriage return at the end of the line in the second item, we are breaking the smart our pager has in order not to show "^M". This can be fixed by changing the sequence to: - force this color; - the line up to but not including the terminating end-of-line; - reset color - end-of-line. where end-of-line is either a single linefeed or a CRLF pair. When the output is not colored, "force this color" and "reset color" sequences are both empty, so we won't have this problem with or without this patch.

The sorting means that all files are nicely grouped by directory. That all works fine. Except when we have rename detection, and suddenly the nicely sorted list of pathnames isn't all that sorted at all. And now the single-pass dirstat walk gets all confused, and you can get results like this: [torvalds@nehalem linux]$ git diff --dirstat=2 -M v2.6.27-rc4..v2.6.27-rc5 3.0% arch/powerpc/configs/ 6.8% arch/arm/configs/ 2.7% arch/powerpc/configs/ 4.2% arch/arm/configs/ 5.6% arch/powerpc/configs/ 8.4% arch/arm/configs/ 5.5% arch/powerpc/configs/ 23.3% arch/arm/configs/ 8.6% arch/powerpc/configs/ 4.0% arch/ 4.4% drivers/usb/musb/ 4.0% drivers/watchdog/ 7.6% drivers/ 3.5% fs/ The trivial fix is to add a sorting pass, fixing it to: [torvalds@nehalem linux]$ git diff --dirstat=2 -M v2.6.27-rc4..v2.6.27-rc5 43.0% arch/arm/configs/ 25.5% arch/powerpc/configs/ 5.3% arch/ 4.4% drivers/usb/musb/ 4.0% drivers/watchdog/ 7.6% drivers/ 3.5% fs/ Spot the difference. In case anybody wonders: it's because of a ton of renames from {include/asm-blackfin => arch/blackfin/include/asm} that just totally messed up the file ordering in between arch/arm and arch/powerpc.

| | | | | | | | | | | | | | | | | | | | | | The code remembered that the last diff output it saw was an empty line, and tried to reset that state whenever it sees a context line, a non-blank new line, or a new hunk. However, this codepath asks the underlying diff engine to feed diff without any context, and the "just saw an empty line" state was not reset if you added a new blank line in the last hunk of your patch, even if it is not the last line of the file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This further enhances xdi_diff_outf() interface so that it takes two common parameters: the callback function that processes one line at a time, and a pointer to its application specific callback data structure. xdi_diff_outf() creates its own "xdiff_emit_state" structure and stashes these two away inside it, which is used by the lowest level output function in the xdiff_outf() callchain, consume_one(), to call back to the application layer. With this restructuring, we lift the requirement that the caller supplied callback data structure embeds xdiff_emit_state structure as its first member.
