Of course, since what descibes a subproject is just the SHA1, that's what we'll use. Add some pretty-printing to make it a bit more obvious what is going on, and we're done.

We'll also want to have the ability to recurse into the subproject and actually diff it recursively, but that will involve a new command line option (I'd suggest "--subproject" and "-S", but the latter is in use by pickaxe), and some very different code. But regardless of ay future recursive behaviour, we need the non-recursive version too (and it should be the default, at least in the absense of config options, so that large superprojects don't default to something extremely expensive).

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.

But no, people keep asking for it, but nobody actually did anything, so I decided I might as well bite the bullet, and instead of telling people they could add a "--follow" flag to "git log" to do what they want to do, I decided that it looks like I just have to do it for them.. The code wasn't actually that complicated, in that the diffstat for this patch literally says "70 insertions(+), 1 deletions(-)", but I will have to admit that in order to get to this fairly simple patch, you did have to know and understand the internal git diff generation machinery pretty well, and had to really be able to follow how commit generation interacts with generating patches and generating the log. So I suspect that while I was right that it wasn't that hard, I might have been expecting too much of random people - this patch does seem to be firmly in the core "Linus or Junio" territory. To make a long story short: I'm sorry for it taking so long until I just did it. I'm not going to guarantee that this works for everybody, but you really can just look at the patch, and after the appropriate appreciative noises ("Ooh, aah") over how clever I am, you can then just notice that the code itself isn't really that complicated. All the real new code is in the new "try_to_follow_renames()" function. It really isn't rocket science: we notice that the pathname we were looking at went away, so we start a full tree diff and try to see if we can instead make that pathname be a rename or a copy from some other previous pathname. And if we can, we just continue, except we show *that* particular diff, and ever after we use the _previous_ pathname. One thing to look out for: the "rename detection" is considered to be a singular event in the _linear_ "git log" output! That's what people want to do, but I just wanted to point out that this patch is *not* carrying around a "commit,pathname" kind of pair and it's *not* going to be able to notice the file coming from multiple *different* files in earlier history. IOW, if you use "git log --follow", then you get the stupid CVS/SVN kind of "files have single identities" kind of semantics, and git log will just pick the identity based on the normal move/copy heuristics _as_if_ the history could be linearized. Put another way: I think the model is broken, but given the broken model, I think this patch does just about as well as you can do. If you have merges with the same "file" having different filenames over the two branches, git will just end up picking _one_ of the pathnames at the point where the newer one goes away. It never looks at multiple pathnames in parallel. And if you understood all that, you probably didn't need it explained, and if you didn't understand the above blathering, it doesn't really mtter to you. What matters to you is that you can now do git log -p --follow builtin-rev-list.c and it will find the point where the old "rev-list.c" got renamed to "builtin-rev-list.c" and show it as such.

This makes"diff -p" hunk headers customizable via gitattributes mechanism. It is based on Johannes's earlier patch that allowed to define a single regexp to be used for everything. The mechanism to arrive at the regexp that is used to define hunk header is the same as other use of gitattributes. You assign an attribute, funcname (because "diff -p" typically uses the name of the function the patch is about as the hunk header), a simple string value. This can be one of the names of built-in pattern (currently, "java" is defined) or a custom pattern name, to be looked up from the configuration file. (in .gitattributes) *.java funcname=java *.perl funcname=perl (in .git/config) [funcname] java = ... # ugly and complicated regexp to override the built-in one. perl = ... # another ugly and complicated regexp to define a new one.

This updates the hunk header customization syntax. The special case 'funcname' attribute is gone. You assign the name of the type of contents to path's "diff" attribute as a string value in .gitattributes like this: *.java diff=java *.perl diff=perl *.doc diff=doc If you supply "diff..funcname" variable via the configuration mechanism (e.g. in $HOME/.gitconfig), the value is used as the regexp set to find the line to use for the hunk header (the variable is called "funcname" because such a line typically is the one that has the name of the function in programming language source text). If there is no such configuration, built-in default is used, if any. Currently there are two default patterns: default and java.

While it was a way to warn the user that the earlier action of the user made the index ineffective as an optimization mechanism, it was felt too loud for the purpose of warning even to experienced users, and also resulted in confusing people new to git. This replaces the "empty" diffs with a single warning message at the end. Having many such paths hurts performance, and you can run "git-update-index --refresh" to update the lstat(2) information recorded in the index in such a case. "git-status" does so as a side effect, and that is more familiar to the end-user, so we recommend it to them. The change affects only "git diff" that outputs patch text, because that is where the annoyance of too many "empty" diff is most strongly felt, and because the warning message can be safely ignored by downstream tools without getting mistaken as part of the patch. For the low-level "git diff-files" and "git diff-index", the traditional behaviour is retained.

The patch adds a new diff_options bitfield member, no_index, that is used instead of the special value of -2 of the rev_info field max_count to indicate that the index is not to be used. This makes it possible to pass that flag down to diffcore_skip_stat_unmatch(), which only has one diff_options parameter. This could even become a cleanup if we removed all assignments of max_count to a value of -2 (viz. replacement of a magic value with a self-documenting field name) but I didn't dare to do that so late in the rc game.. The no_index bit, if set, then tells diffcore_skip_stat_unmatch() to not account for any skipped stat-mismatches, which avoids the suggestion to run git-status.

It robbed cache-dirty information from people who valued it, while still asking users to run "update-index --refresh". It was hoped that the new behaviour would at least have some educational value, but not showing the cache-dirty paths like before meant that the user would not even know easily which paths were cache-dirty, and it made the need to refresh the index look like even more unnecessary chore. This commit reinstates the traditional behaviour, but with a twist. By default, the empty "diff --git" output is totally squelched out from "git diff" output. At the end of the command, it automatically runs "update-index --refresh" as needed, without even bothering the user. In other words, people who do not care about the cache-dirtyness do not even have to see the warning. The traditional behaviour to see the stat-dirty output and to bypassing the overhead of content comparison can be specified by setting the configuration variable diff.autorefreshindex to false.

Instead of just checking the limit against the number of potential rename destinations, we verify that the rename matrix (which is what really matters) doesn't grow ridiculously large, and we also make sure that we don't overflow when doing the matrix size calculation. This also changes the default limits from unlimited, to a rename matrix that is limited to 100 entries on a side. You can raise it with the config entry, or by using the "-l" command line flag, but at least the default is now a sane number that avoids spending lots of time (and memory) in situations that likely don't merit it. The choice of default value is of course very debatable. Limiting the rename matrix to a 100x100 size will mean that even if you have just one obvious rename, but you also create (or delete) 10,000 files, the rename matrix will be so big that we disable the heuristics. Sounds reasonable to me, but let's see if people hit this (and, perhaps more importantly, actually *care*) in real life.

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.

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. As a side effect of the refactor in builtin-apply.c, the length of the bar graphs in diffstats are not affected anymore by the fact that the path was clipped.

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.

There are inherently O(n^2) comparisons, so it pays in CPU time to hoist the (rather expensive) computation of the fingerprint out of that loop (or to cache it once we have computed it once). Previously, we didn't keep the filespec information around because then we had the potential to consume a great deal of memory. However, instead of keeping all of the filespec data, we can instead just keep the fingerprint. This patch implements and uses diff_free_filespec_data_large to accomplish that goal. We also have to change estimate_similarity not to needlessly repopulate the filespec data when we already have the hash. Practical tests showed 4.5x speedup for a 10% memory usage increase.

This avoids unnecessary allocations, but the real reason behind this is a future enhancement: we will want to track shared data across the copy/rename detection. In order to efficiently notice when a filespec is used by a rename, the rename machinery wants to keep track of a rename usage count which is shared across all different users of the filespec.

That's really silly, since we can just keep a count of users around, and replace all those complex and expensive loops with just testing that simple counter (but this all depends on the previous commit that shared the diff_filespec data structure by using a separate reference count). Note that the reference count is not the same as the rename count: they behave otherwise rather similarly, but the reference count is tied to the allocation (and decremented at de-allocation, so that when it turns zero we can get rid of the memory), while the rename count is tied to the renames and is decremented when we find a rename (so that when it turns zero we know that it was a rename, not a copy).

This introduces core.whitespace configuration variable that lets you specify the definition of "whitespace error". Currently there are two kinds of whitespace errors defined: * trailing-space: trailing whitespaces at the end of the line. * space-before-tab: a SP appears immediately before HT in the indent part of the line. You can specify the desired types of errors to be detected by listing their names (unique abbreviations are accepted) separated by comma. By default, these two errors are always detected, as that is the traditional behaviour. You can disable detection of a particular type of error by prefixing a '-' in front of the name of the error, like this: [core] whitespace = -trailing-space This patch teaches the code to output colored diff with DIFF_WHITESPACE color to highlight the detected whitespace errors to honor the new configuration.

It exits with status 1 otherwise. If a script wants "true"/"false" answer to the standard output of the command, it can pass an additional boolean parameter to its command line, telling if its standard output is a terminal, like this: git config --get-colorbool color.diff true When called like this, the command outputs "true" to its standard output if color is to be used (i.e. "color.diff" says "always", "auto", or "true"), and "false" otherwise.

The scripts would never have successfully parsed "--numstat -z -M" in the old format. This fixes the output format in a (hopefully minimally) backward incompatible way. * The output without -z is not changed. This has given a good way for humans to view added and deleted lines separately, and showing the path in combined, shorter way would preserve readability. * The output with -z is unchanged for paths that do not involve renames. Existing scripts that do not pass -M/-C are not affected at all. * The output with -z for a renamed path is shown in a format that can easily be distinguished from an unrenamed path. This is based on Jakub Narebski's patch. Bugs and documentation typos are mine.

The checking is based on lines of content rather than patch lines (in other words, the caller must strip the leading "+" or "-"); this was suggested by Junio on the mailing list to allow for a future extension to "git show" to display whitespace errors in blobs. At the same time we teach it to report all classes of whitespace errors found for a given line rather than reporting only the first found error.

The plumbing specifically avoids calling this function, since it doesn't want things like automatic color or rename detection. However, some diff options should be set for both plumbing and porcelain. For example, one can still turn on color in git-diff-files using the --color command line option. This means we want the color config from color.diff.* (so that once color is on, we use the user's preferred scheme), but _not_ the color.diff variable. We split the diff config into "ui" and "basic", where "basic" is suitable for use by plumbing (so _most_ things affecting the output should still go into the "ui" part).

A file that contains a mixture of LF and CRLF before the commit cannot be recreated by git. For text files this is the right thing to do: it corrects line endings such that we have only LF line endings in the repository. But for binary files that are accidentally classified as text the conversion can corrupt data. If you recognize such corruption early you can easily fix it by setting the conversion type explicitly in .gitattributes. Right after committing you still have the original file in your work tree and this file is not yet corrupted. You can explicitly tell git that this file is binary and git will handle the file appropriately. Unfortunately, the desired effect of cleaning up text files with mixed line endings and the undesired effect of corrupting binary files cannot be distinguished. In both cases CRLFs are removed in an irreversible way. For text files this is the right thing to do because CRLFs are line endings, while for binary files converting CRLFs corrupts data. This patch adds a mechanism that can either warn the user about an irreversible conversion or can even refuse to convert. The mechanism is controlled by the variable core.safecrlf, with the following values: - false: disable safecrlf mechanism - warn: warn about irreversible conversions - true: refuse irreversible conversions The default is to warn. Users are only affected by this default if core.autocrlf is set. But the current default of git is to leave core.autocrlf unset, so users will not see warnings unless they deliberately chose to activate the autocrlf mechanism. The safecrlf mechanism's details depend on the git command. The general principles when safecrlf is active (not false) are: - we warn/error out if files in the work tree can modified in an irreversible way without giving the user a chance to backup the original file. - for read-only operations that do not modify files in the work tree we do not not print annoying warnings. There are exceptions. Even though... - "git add" itself does not touch the files in the work tree, the next checkout would, so the safety triggers; - "git apply" to update a text file with a patch does touch the files in the work tree, but the operation is about text files and CRLF conversion is about fixing the line ending inconsistencies, so the safety does not trigger; - "git diff" itself does not touch the files in the work tree, it is often run to inspect the changes you intend to next "git add". To catch potential problems early, safety triggers. The concept of a safety check was originally proposed in a similar way by Linus Torvalds.

What I mean by that is that it's often interesting to see exactly which sub-directories are impacted by a patch, and to what degree - even if you don't perhaps care so much about the individual files themselves. What makes the concept more interesting is that the "impact" is often hierarchical: in the kernel, for example, something could either have a very localized impact to "fs/ext3/" and then it's interesting to see that such a patch changes mostly that subdirectory, but you could have another patch that changes some generic VFS-layer issue which affects _many_ subdirectories that are all under "fs/", but none - or perhaps just a couple of them - of the individual filesystems are interesting in themselves. So what commonly happens is that you may have big changes in a specific sub-subdirectory, but still also significant separate changes to the subdirectory leading up to that - maybe you have significant VFS-level changes, but *also* changes under that VFS layer in the NFS-specific directories, for example. In that case, you do want the low-level parts that are significant to show up, but then the insignificant ones should show up as under the more generic top-level directory. This patch shows all of that with "--dirstat". The output can be either something simple like commit 81772fe...

I'd like to stress that the "15.3% fs/" mentioned above is the stuff that is under fs/ but that was _not_ significant enough to report on its own. So the above does _not_ mean that 15.3% of the work was under fs/ per se, because that 15.3% does *not* include the already-reported 7.6% of afs, 7.6% of fuse etc. If you want to enable "cumulative" directory statistics, you can use the "--cumulative" flag, which adds up percentages recursively even when they have been already reported for a sub-directory. That cumulative output is disabled if *all* of the changes in one subdirectory come from a deeper subdirectory, to avoid repeating subdirectories all the way to the root. For an example of the cumulative reporting, the above commit becomes commit e231c2e... Author: David Howells Date: Thu Feb 7 00:15:26 2008 -0800 Convert ERR_PTR(PTR_ERR(p)) instances to ERR_CAST(p) 20.5% crypto/ 7.6% fs/afs/ 7.6% fs/fuse/ 7.6% fs/gfs2/ 5.1% fs/jffs2/ 5.1% fs/nfs/ 5.1% fs/nfsd/ 7.6% fs/reiserfs/ 61.5% fs/ 7.6% net/rxrpc/ 10.2% security/keys/ in which the commit percentages now obviously add up to much more than 100%: now the changes that were already reported for the sub-directories under fs/ are then cumulatively included in the whole percentage of fs/ (ie now shows 61.5% as opposed to the 15.3% without the cumulative reporting). The default reporting limit has been arbitrarily set at 3%, which seems to be a pretty good cut-off, but you can specify the cut-off manually by giving it as an option parameter (eg "--dirstat=5" makes the cut-off be at 5% instead) NOTE! The percentages are purely about the total lines added and removed, not anything smarter (or dumber) than that. Also note that you should not generally expect things to add up to 100%: not only does it round down, we don't report leftover scraps (they add up to the top-level change count, but we don't even bother reporting that, it only reports subdirectories). Quite frankly, as a top-level manager this is really convenient for me, but it's going to be very boring for git itself since there are few subdirectories. Also, don't expect things to make tons of sense if you combine this with "-M" and there are cross-directory renames etc. But even for git itself, you can get some fun statistics. Try out git log --dirstat and see the occasional mentions of things like Documentation/, git-gui/, gitweb/ and gitk-git/. Or try out something like git diff --dirstat v1.5.0..v1.5.4 which does kind of git an overview that shows *something*. But in general, the output is more exciting for big projects with deeper structure, and doing a git diff --dirstat v2.6.24..v2.6.25-rc1 on the kernel is what I actually wrote this for!

When you start from a subdirectory: $ git diff --relative shows only the diff that is inside your current subdirectory, and without $prefix part. People who usually live in subdirectories may like it. There are a few things I should also mention about the change: - This works not just with diff but also works with the log family of commands, but the history pruning is not affected. In other words, if you go to a subdirectory, you can say: $ git log --relative -p but it will show the log message even for commits that do not touch the current directory. You can limit it by giving pathspec yourself: $ git log --relative -p . This originally was not a conscious design choice, but we have a way to affect diff pathspec and pruning pathspec independently. IOW "git log --full-diff -p ." tells it to prune history to commits that affect the current subdirectory but show the changes with full context. I think it makes more sense to leave pruning independent from --relative than the obvious alternative of always pruning with the current subdirectory, which would break the symmetry. - Because this works also with the log family, you could format-patch a single change, limiting the effect to your subdirectory, like so: $ cd gitk-git $ git format-patch -1 --relative 911f1eb But because that is a special purpose usage, this option will never become the default, with or without repository or user preference configuration. The risk of producing a partial patch and sending it out by mistake is too great if we did so. - This is inherently incompatible with --no-index, which is a bolted-on hack that does not have much to do with git itself. I didn't bother checking and erroring out on the combined use of the options, but probably I should.

This change removes all obvious useless if-before-free tests. E.g., it replaces code like this: if (some_expression) free (some_expression); with the now-equivalent: free (some_expression); It is equivalent not just because POSIX has required free(NULL) to work for a long time, but simply because it has worked for so long that no reasonable porting target fails the test. Here's some evidence from nearly 1.5 years ago: http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html FYI, the change below was prepared by running the following: git ls-files -z | xargs -0 \ perl -0x3b -pi -e \ 's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s' Note however, that it doesn't handle brace-enclosed blocks like "if (x) { free (x); }". But that's ok, since there were none like that in git sources. Beware: if you do use the above snippet, note that it can produce syntactically invalid C code. That happens when the affected "if"-statement has a matching "else". E.g., it would transform this if (x) free (x); else foo (); into this: free (x); else foo (); There were none of those here, either. If you're interested in automating detection of the useless tests, you might like the useless-if-before-free script in gnulib: [it *does* detect brace-enclosed free statements, and has a --name=S option to make it detect free-like functions with different names] http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren .

There was a mistake in the diffcore_skip_stat_unmatch() that was meant to clean up the stat-only difference for running diff between the index and work tree and diff between the tree and the work tree, to cause it re-read from the submodule repository HEAD. When ce_stat_match() says work tree is different, we should always say 0{40} on the work tree side. This patch fixes the issue, and adds tests.

Testing[1] has shown that on modern hardware, a limit of 200 adds about a second of computation time, and a limit of 500 adds about 5 seconds of computation time. This patch bumps the default limit to 200 for viewing diffs, and to 500 for performing a merge. The limit for generating git-status templates is set independently; we bump it up to 200 here, as well, to match the diff limit.

In this case, there is no +/- "graph" after the number of changed lines. However, we output the space separator unconditionally, meaning that these lines contained a trailing space character. This isn't a huge problem, but in cleaning up the output we are able to eliminate some trailing whitespace from a test vector.

This patch restores the old behaviour. Besides Linus' arguments in the log message of 50f575fc, resetting color before printing newline is also important to keep 'git add --patch' happy. If the last line(s) of a file are removed, then that hunk will end with a colored line. However, if the newline comes before the color reset, then the diff output will have an additional line at the end containing only the reset sequence. This causes trouble in git-add--interactive.perl's parse_diff function, because @colored will have one more element than @diff, and that last element will contain the color reset. The elements of these arrays will then be copied to @hunk, but only as many as the number of elements in @diff. As a result the last color reset is lost and all subsequent terminal output will be printed in color.

The first is to write a newline preceding the boundary. This is needed because MIME defines the encapsulation boundary as including the preceding CRLF (or in this case, just LF), so we should be writing one. Without this, the last newline in the pre-diff content is consumed instead. The second change is to always write the line termination character (default: newline) even when using --inline or --attach. This is simply to improve the aesthetics of the resulting message. When using --inline an email client should render the resulting message identically to the non-inline version. And when using --attach this adds a blank line preceding the attachment in the email, which is visually attractive.

With this restructuring, we lift the requirement that the caller supplied callback data structure embeds xdiff_emit_state structure as its first member.

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 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.

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.

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 Signed-off-by: Junio C Hamano --- Documentation/gitattributes.txt | 4 ++-- diff.c | 5 +++++ t/t4018-diff-funcname.sh | 2 +- 3 files changed, 8 insertions(+), 3 deletions(-) (limited to 'diff.c') diff --git a/Documentation/gitattributes.txt b/Documentation/gitattributes.txt index 94e6752aa2..9259637609 100644 --- a/Documentation/gitattributes.txt +++ b/Documentation/gitattributes.txt @@ -288,13 +288,13 @@ for paths. *.tex diff=tex ------------------------ -Then, you would define "diff.tex.funcname" configuration to +Then, you would define "diff.tex.xfuncname" configuration to specify a regular expression that matches a line that you would want to appear as the hunk header, like this: ------------------------ [diff "tex"] - funcname = "^\\(\\\\\\(sub\\)*section{.*\\)$" + xfuncname = "^(\\\\(sub)*section\\{.*)$" ------------------------ Note.

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.

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.

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.

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.

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.

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 Signed-off-by: Shawn O.

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.

This was a bad idea for a number of reasons: - it made the semantics of fill_mmfile unclear. In some cases, it was allocating data (if a text conversion occurred), and in some cases not (if we could use the data directly from the filespec). But the caller had no idea which had happened, and so didn't know whether the memory should be freed - similarly, the caller had no idea if a text conversion had occurred, and so didn't know whether the contents should be treated as binary or not. This meant that we incorrectly guessed that text-converted content was binary and didn't actually show it (unless the user overrode us with "diff.foo.binary = false", which then created problems in plumbing where the text conversion did _not_ occur) - not all callers of fill_mmfile want the text contents. In particular, we don't really want diffstat, whitespace checks, patch id generation, etc, to look at the converted contents. This patch pulls the conversion code directly into builtin_diff, so that we only see the conversion when generating an actual patch. We also then know whether we are doing a conversion, so we can check the binary-ness and free the data from the mmfile appropriately (the previous version leaked quite badly when text conversion was used) Signed-off-by: Jeff King Signed-off-by: Junio C Hamano --- diff.c | 48 +++++++++++++++++++++++++++++++++++------------- t/t4030-diff-textconv.sh | 6 +++--- 2 files changed, 38 insertions(+), 16 deletions(-) (limited to 'diff.c') diff --git a/diff.c b/diff.c index d1fd594ba3..6f01595ece 100644 --- a/diff.c +++ b/diff.c @@ -294,18 +294,8 @@ static int fill_mmfile(mmfile_t *mf, struct diff_filespec *one) else if (diff_populate_filespec(one, 0)) return -1; - diff_filespec_load_driver(one); - if (one->driver->textconv) { - size_t size; - mf->ptr = run_textconv(one->driver->textconv, one, &size); - if (!mf->ptr) - return -1; - mf->size = size; - } - else { - mf->ptr = one->data; - mf->size = one->size; - } + mf->ptr = one->data; + mf->size = one->size; return 0; } @@ -1323,6 +1313,14 @@ void diff_set_mnemonic_prefix(struct diff_options *options, const char *a, const options->b_prefix = b; } +static const char *get_textconv(struct diff_filespec *one) +{ + if (!DIFF_FILE_VALID(one)) + return NULL; + diff_filespec_load_driver(one); + return one->driver->textconv; +} + static void builtin_diff(const char *name_a, const char *name_b, struct diff_filespec *one, @@ -1337,6 +1335,7 @@ static void builtin_diff(const char *name_a, const char *set = diff_get_color_opt(o, DIFF_METAINFO); const char *reset = diff_get_color_opt(o, DIFF_RESET); const char *a_prefix, *b_prefix; + const char *textconv_one, *textconv_two; diff_set_mnemonic_prefix(o, "a/", "b/"); if (DIFF_OPT_TST(o, REVERSE_DIFF)) { @@ -1390,8 +1389,12 @@ static void builtin_diff(const char *name_a, if (fill_mmfile(&mf1, one) < 0 || fill_mmfile(&mf2, two) < 0) die("unable to read files to diff"); + textconv_one = get_textconv(one); + textconv_two = get_textconv(two); + if (!DIFF_OPT_TST(o, TEXT) && - (diff_filespec_is_binary(one) || diff_filespec_is_binary(two))) { + ( (diff_filespec_is_binary(one) && !textconv_one) || + (diff_filespec_is_binary(two) && !textconv_two) )) { /* Quite common confusing case */ if (mf1.size == mf2.size && !memcmp(mf1.ptr, mf2.ptr, mf1.size)) @@ -1412,6 +1415,21 @@ static void builtin_diff(const char *name_a, struct emit_callback ecbdata; const struct userdiff_funcname *pe; + if (textconv_one) { + size_t size; + mf1.ptr = run_textconv(textconv_one, one, &size); + if (!mf1.ptr) + die("unable to read files to diff"); + mf1.size = size; + } + if (textconv_two) { + size_t size; + mf2.ptr = run_textconv(textconv_two, two, &size); + if (!mf2.ptr) + die("unable to read files to diff"); + mf2.size = size; + } + pe = diff_funcname_pattern(one); if (!pe) pe = diff_funcname_pattern(two); @@ -1443,6 +1461,10 @@ static void builtin_diff(const char *name_a, &xpp, &xecfg, &ecb); if (DIFF_OPT_TST(o, COLOR_DIFF_WORDS)) free_diff_words_data(&ecbdata); + if (textconv_one) + free(mf1.ptr); + if (textconv_two) + free(mf2.ptr); } free_ab_and_return: diff --git a/t/t4030-diff-textconv.sh b/t/t4030-diff-textconv.sh index 1b0964843e..090a21d0b5 100755 --- a/t/t4030-diff-textconv.sh +++ b/t/t4030-diff-textconv.sh @@ -52,7 +52,7 @@ test_expect_success 'setup textconv filters' ' git config diff.fail.textconv false ' -test_expect_failure 'diff produces text' ' +test_expect_success 'diff produces text' ' git diff HEAD^ HEAD >diff && find_diff actual && test_cmp expect.text actual @@ -64,7 +64,7 @@ test_expect_success 'diff-tree produces binary' ' test_cmp expect.binary actual ' -test_expect_failure 'log produces text' ' +test_expect_success 'log produces text' ' git log -1 -p >log && find_diff actual && test_cmp expect.text actual @@ -80,7 +80,7 @@ cat >expect.stat <<'EOF' file | Bin 2 -> 4 bytes 1 files changed, 0 insertions(+), 0 deletions(-) EOF -test_expect_failure 'diffstat does not run textconv' ' +test_expect_success 'diffstat does not run textconv' ' echo file diff=fail >.gitattributes && git diff --stat HEAD^ HEAD >actual && test_cmp expect.stat actual -- cgit v1.3 From c7534ef4a12bb44806d522fc8e3961e390f9169b Mon Sep 17 00:00:00 2001 From: Jeff King Date: Sun, 26 Oct 2008 00:45:55 -0400 Subject: userdiff: require explicitly allowing textconv Diffs that have been produced with textconv almost certainly cannot be applied, so we want to be careful not to generate them in things like format-patch. This introduces a new diff options, ALLOW_TEXTCONV, which controls this behavior. It is off by default, but is explicitly turned on for the "log" family of commands, as well as the "diff" porcelain (but not diff-* plumbing). Because both text conversion and external diffing are controlled by these diff options, we can get rid of the "plumbing versus porcelain" distinction when reading the config.

Similarly gitlink components just end up as the text "Subproject commit $sha1", which we should leave intact.

In that case, we _do_ show the textconv for any part which is the addition or removal of a file we would ordinarily textconv, since it is purely acting on the file contents.

Currently, there is no way for them to specify that they would like to see the text-converted version of the diff. This patch adds a "--textconv" option to allow such a plumbing user to allow text conversion. The user can then tell the viewer whether or not they would like text conversion enabled. While it may be tempting add a configuration option rather than requiring each plumbing user to be configured to pass --textconv, that is somewhat dangerous. Text-converted diffs generally cannot be applied directly, so each plumbing user should "opt in" to generating such a diff, either by explicit request of the user or by confirming that their output will not be fed to patch.

This means that if you end up with a rewrite diff for a binary file, you get lots of raw binary goo in your patch. Instead, if we have binary files, then let's just skip emit_rewrite_diff altogether. We will already have shown the "dissimilarity index" line, so it is really about the diff contents. If binary diffs are turned off, the "Binary files a/file and b/file differ" message should be the same in either case. If we do have binary patches turned on, there isn't much point in making a less-efficient binary patch that does a total rewrite; no human is going to read it, and since binary patches don't apply with any fuzz anyway, the result of application should be the same.

For --inter-hunk-context=1, the resulting patch has the same number of lines but shows uninterrupted context instead of a context header line in between. Patches generated with this option are easier to read but are also more likely to conflict if the file to be patched contains other changes. This patch keeps the default for this option at 0. It is intended to just make the feature available in order to see its advantages and downsides.

Therefore, it could get away with a very simple scheme: it copied the hunks, substituted newlines for each white space character, called libxdiff with the processed text, and then identified the text to output by the offsets (which agreed since the original text had the same length). This code was ugly, for a number of reasons: - it was impossible to introduce 0-character word boundaries, - we had to print everything word by word, and - the code needed extra special handling of newlines in the removed part. Fix all of these issues by processing the text such that - we build word lists, separated by newlines, - we remember the original offsets for every word, and - after calling libxdiff on the wordlists, we parse the hunk headers, and find the corresponding offsets, and then - we print the removed/added parts in one go. The pre and post samples in the test were provided by Santi Béjar. Note that there is some strange special handling of hunk headers where one line range is 0 due to POSIX: in this case, the start is one too low. In other words a hunk header '@@ -1,0 +2 @@' actually means that the line must be added after the _second_ line of the pre text, _not_ the first.

To allow for that, you can specify a regular expression describing what makes a word with git diff --color-words='[A-Za-z0-9]+' Note that words cannot contain newline characters. As suggested by Thomas Rast, the words are the exact matches of the regular expression. Note that a regular expression beginning with a '^' will match only a word at the beginning of the hunk, not a word at the beginning of a line, and is probably not what you want.

The former cleans up its tempfiles in the face of premature death (i.e., by die() or by signal), but the latter does not. After this patch, they will both use the same cleanup routines. To make clear what the change is, let me first explain what happens now: - run_external_diff uses a static global array of 2 diff_tempfile structs (since it knows it will always need exactly 2 tempfiles). It calls prepare_temp_file (which doesn't know anything about the global array) on each of the structs, creating the tempfiles that need to be cleaned up. It then registers atexit and signal handlers to look through the global array and remove the tempfiles. If it succeeds, it calls the handler manually (which marks the tempfile structs as unused). - textconv has its own tempfile struct, which it allocates using prepare_temp_file and cleans up manually. No signal or atexit handlers. The new code moves the installation of cleanup handlers into the prepare_temp_file function. Which means that that function now has to understand that there is static tempfile storage. So what happens now is: - run_external_diff calls prepare_temp_file - prepare_temp_file calls claim_diff_tempfile, which allocates an unused slot from our global array - prepare_temp_file installs (if they have not already been installed) atexit and signal handlers for cleanup - prepare_temp_file sets up the tempfile as usual - prepare_temp_file returns a pointer to the allocated tempfile The advantage being that run_external_diff no longer has to care about setting up cleanup handlers. Now by virtue of calling prepare_temp_file, run_textconv gets the same benefit, as will any future users of prepare_temp_file. There are also a few side benefits to the specific implementation: - we now install cleanup handlers _before_ allocating the tempfile, closing a race which could leave temp cruft - when allocating a slot in the global array, we will now detect a situation where the old slots were not properly vacated (i.e., somebody forgot to call remove upon leaving the function). In the old code, such a situation would silently overwrite the tempfile names, meaning we would forget to clean them up. The new code dies with a bug warning. - we make sure only to install the signal handler once. This isn't a big deal, since we are just overwriting the old handler, but will become an issue when a later patch converts the code to use sigchain Signed-off-by: Jeff King Signed-off-by: Junio C Hamano --- diff.c | 107 +++++++++++++++++++++++++++++++++-------------------------------- 1 file changed, 55 insertions(+), 52 deletions(-) (limited to 'diff.c') diff --git a/diff.c b/diff.c index d23548292a..3cfc0b636c 100644 --- a/diff.c +++ b/diff.c @@ -165,6 +165,33 @@ static struct diff_tempfile { char tmp_path[PATH_MAX]; } diff_temp[2]; +static struct diff_tempfile *claim_diff_tempfile(void) { + int i; + for (i = 0; i < ARRAY_SIZE(diff_temp); i++) + if (!diff_temp[i].name) + return diff_temp + i; + die("BUG: diff is failing to clean up its tempfiles"); +} + +static int remove_tempfile_installed; + +static void remove_tempfile(void) +{ + int i; + for (i = 0; i < ARRAY_SIZE(diff_temp); i++) + if (diff_temp[i].name == diff_temp[i].tmp_path) { + unlink(diff_temp[i].name); + diff_temp[i].name = NULL; + } +} + +static void remove_tempfile_on_signal(int signo) +{ + remove_tempfile(); + signal(SIGINT, SIG_DFL); + raise(signo); +} + static int count_lines(const char *data, int size) { int count, ch, completely_empty = 1, nl_just_seen = 0; @@ -1857,10 +1884,11 @@ static void prep_temp_blob(struct diff_tempfile *temp, sprintf(temp->mode, "%06o", mode); } -static void prepare_temp_file(const char *name, - struct diff_tempfile *temp, - struct diff_filespec *one) +static struct diff_tempfile *prepare_temp_file(const char *name, + struct diff_filespec *one) { + struct diff_tempfile *temp = claim_diff_tempfile(); + if (!DIFF_FILE_VALID(one)) { not_a_valid_file: /* A '-' entry produces this for file-2, and @@ -1869,7 +1897,13 @@ static void prepare_temp_file(const char *name, temp->name = "/dev/null"; strcpy(temp->hex, "."); strcpy(temp->mode, "."); - return; + return temp; + } + + if (!remove_tempfile_installed) { + atexit(remove_tempfile); + signal(SIGINT, remove_tempfile_on_signal); + remove_tempfile_installed = 1; } if (!one->sha1_valid || @@ -1909,7 +1943,7 @@ static void prepare_temp_file(const char *name, */ sprintf(temp->mode, "%06o", one->mode); } - return; + return temp; } else { if (diff_populate_filespec(one, 0)) @@ -1917,24 +1951,7 @@ static void prepare_temp_file(const char *name, prep_temp_blob(temp, one->data, one->size, one->sha1, one->mode); } -} - -static void remove_tempfile(void) -{ - int i; - - for (i = 0; i < 2; i++) - if (diff_temp[i].name == diff_temp[i].tmp_path) { - unlink(diff_temp[i].name); - diff_temp[i].name = NULL; - } -} - -static void remove_tempfile_on_signal(int signo) -{ - remove_tempfile(); - signal(SIGINT, SIG_DFL); - raise(signo); + return temp; } /* An external diff command takes: @@ -1952,34 +1969,22 @@ static void run_external_diff(const char *pgm, int complete_rewrite) { const char *spawn_arg[10]; - struct diff_tempfile *temp = diff_temp; int retval; - static int atexit_asked = 0; - const char *othername; const char **arg = &spawn_arg[0]; - othername = (other?

However, if we want to clean up two _different_ things, we run into a problem. The most recently installed handler will run, but when it removes itself as a handler, it doesn't put back the first handler. This patch introduces sigchain, a tiny library for handling a stack of signal handlers. You sigchain_push each handler, and use sigchain_pop to restore whoever was before you in the stack.

Some callsites checked only SIGINT, while others checked a variety of death-dealing signals. This patch factors out those signals to a single function, and then calls it everywhere. For some sites, that means this is a simple clean up. For others, it is an improvement in that they will now properly clean themselves up after a larger variety of signals.

However, the code reused the single set of metainfo lines. As the blob object names recorded on the index lines are usually not used nor validated on the receiving end, this is not an issue with normal use of the resulting patch. However, when accepting a binary patch to delete a blob, git-apply verified that the postimage blob object name on the index line is 0{40}, hence a patch that deletes a regular file blob that records binary contents to create a blob with different filetype (e.g. a symbolic link) failed to apply. "git am -3" also uses the blob object names recorded on the index line, so it would also misbehave when synthesizing a preimage tree. This moves the code to generate metainfo lines around, so that two independent sets of metainfo lines are used for the split halves. Additional tests by Jeff King.

I also told them that if they want to make it the default, they can just add [diff] renames to their ~/.gitconfig file. And while I was thinking about that, I wanted to also check whether you can then mark individual projects to _not_ have that default in the per-repository .git/config file. And you can't. Currently you cannot have a global "enable renames by default" and then a local ".. but not for _this_ project". Why? Because if somebody writes [diff] renames = no we simply ignore it, rather than resetting "diff_detect_rename_default" back to zero. Fixed thusly.

Use die_errno() where we check a system/library call that sets errno on failure, or one of the following that wrap such calls: Function Passes on error from -------- -------------------- odb_pack_keep open read_ancestry fopen read_in_full xread strbuf_read xread strbuf_read_file open or strbuf_read_file strbuf_readlink readlink write_in_full xwrite Signed-off-by: Thomas Rast Signed-off-by: Junio C Hamano --- abspath.c | 12 ++++++------ builtin-add.c | 2 +- builtin-apply.c | 6 +++--- builtin-archive.c | 4 ++-- builtin-blame.c | 8 ++++---- builtin-clone.c | 10 +++++----- builtin-commit.c | 5 +++-- builtin-fast-export.c | 2 +- builtin-fmt-merge-msg.c | 2 +- builtin-fsck.c | 2 +- builtin-init-db.c | 21 +++++++++++---------- builtin-log.c | 4 ++-- builtin-mailsplit.c | 6 +++--- builtin-merge.c | 21 ++++++++++++--------- builtin-rev-parse.c | 2 +- builtin-revert.c | 2 +- builtin-stripspace.c | 2 +- builtin-tag.c | 2 +- builtin-tar-tree.c | 2 +- combine-diff.c | 2 +- diff.c | 6 +++--- entry.c | 2 +- fast-import.c | 4 ++-- hash-object.c | 2 +- ll-merge.c | 2 +- mktag.c | 2 +- read-cache.c | 2 +- setup.c | 10 +++++----- transport.c | 4 ++-- unpack-file.c | 2 +- 30 files changed, 79 insertions(+), 74 deletions(-) (limited to 'diff.c') diff --git a/abspath.c b/abspath.c index 649f34f833..4bee0ba1ec 100644 --- a/abspath.c +++ b/abspath.c @@ -41,13 +41,13 @@ const char *make_absolute_path(const char *path) if (*buf) { if (!*cwd && !getcwd(cwd, sizeof(cwd))) - die ("Could not get current working directory"); + die_errno ("Could not get current working directory"); if (chdir(buf)) - die ("Could not switch to '%s'", buf); + die_errno ("Could not switch to '%s'", buf); } if (!getcwd(buf, PATH_MAX)) - die ("Could not get current working directory"); + die_errno ("Could not get current working directory"); if (last_elem) { int len = strlen(buf); @@ -63,7 +63,7 @@ const char *make_absolute_path(const char *path) if (!lstat(buf, &st) && S_ISLNK(st.st_mode)) { len = readlink(buf, next_buf, PATH_MAX); if (len < 0) - die ("Invalid symlink: %s", buf); + die_errno ("Invalid symlink '%s'", buf); if (PATH_MAX <= len) die("symbolic link too long: %s", buf); next_buf[len] = '\0'; @@ -75,7 +75,7 @@ const char *make_absolute_path(const char *path) } if (*cwd && chdir(cwd)) - die ("Could not change back to '%s'", cwd); + die_errno ("Could not change back to '%s'", cwd); return buf; } @@ -109,7 +109,7 @@ const char *make_nonrelative_path(const char *path) } else { const char *cwd = get_pwd_cwd(); if (!cwd) - die("Cannot determine the current working directory"); + die_errno("Cannot determine the current working directory"); if (snprintf(buf, PATH_MAX, "%s/%s", cwd, path) >= PATH_MAX) die("Too long path: %.*s", 60, path); } diff --git a/builtin-add.c b/builtin-add.c index c1b229a9d8..8f651c137a 100644 --- a/builtin-add.c +++ b/builtin-add.c @@ -220,7 +220,7 @@ int edit_patch(int argc, const char **argv, const char *prefix) launch_editor(file, NULL, NULL); if (stat(file, &st)) - die("Could not stat '%s'", file); + die_errno("Could not stat '%s'", file); if (!st.st_size) die("Empty patch.

Add xdiff_clear_find_func(), which frees the memory allocated by the former, making the API complete. Also, use the new function in diff.c (the only call site of xdiff_set_find_func()) to clean up after ourselves.
