* Convert existing die(..., strerror(errno)) to die_errno()Thomas Rast2009-06-27
| | | | | | | | | | | Change calls to die(..., strerror(errno)) to use the new die_errno(). In the process, also make slight style adjustments: at least state _something_ about the function that failed (instead of just printing the pathname), and put paths in single quotes.

* reorder ALLOW_TEXTCONV option settingJeff King2008-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | Right now for the diff porcelain and the log family, we call: init_revisions(); setup_revisions(); DIFF_OPT_SET(ALLOW_TEXTCONV); However, that means textconv will _always_ be on, instead of being a default that can be manipulated with setup_revisions. Instead, we want: init_revisions(); DIFF_OPT_SET(ALLOW_TEXTCONV); setup_revisions(); which is what this patch does. We'll go ahead and move the callsite in wt-status, also; even though the user can't pass any options here, it is a cleanup that will help avoid any surprise later if the setup_revisions line is changed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This can do the lstat() storm in parallel, giving potentially much improved performance for cold-cache cases or things like NFS that have weak metadata caching. Just use "read_cache_preload()" instead of "read_cache()" to force an optimistic preload of the index stat data. The function takes a pathspec as its argument, allowing us to preload only the relevant portion of the index.

| | | | | | | | | | | | | | | | | | | | | | | | The original intention of 72909be (Add diff-option --ext-diff, 2007-06-30) was to optionally allow the use of external diff viewer in "git log" family (while keeping them disabled by default). It exposed the "allow external diff" bit to the UI, but forgot to adjust the "git diff" codepath that was set up to always allow use of the external diff viewer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. This was an attempt to control the same thing, but suffered from being too coarse-grained. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | According to the message of commit 0fe7c1de16f71312e6adac4b85bddf0d62a47168, "git diff" with three or more trees expects the merged tree first followed by the parents, in order. However, this command reversed the order of its arguments, resulting in confusing diffs. A comment /* Again, the revs are all reverse */ suggested there was a reason for this, but I can't figure out the reason, so I removed the reversal of the arguments. Test case included.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With a new configuration "diff.mnemonicprefix", "git diff" shows the differences between various combinations of preimage and postimage trees with prefixes different from the standard "a/" and "b/".

"git diff" compares the (i)ndex and the (w)ork tree; "git diff HEAD" compares a (c)ommit and the (w)ork tree; "git diff --cached" compares a (c)ommit and the (i)ndex; "git-diff HEAD:file1 file2" compares an (o)bject and a (w)ork tree entity; "git diff --no-index a b" compares two non-git things (1) and (2).

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. Signed-off-by: Junio C Hamano <gitster@pobox.com>

* refresh_index_quietly(): express "optional" nature of index writing betterJunio C Hamano2007-11-08
| | | | | | | | | | | | | | | | | The point of the part of the code this patch touches is that if we modified the active_cache, we try to write it out and make it the index file for later users to use by calling "commit_locked_index", but we do not really care about the failure from this sequence because it is done purely as an optimization. The original code called three functions primarily for their side effects but as condition of an if statement, which is admittedly a bad style. Incidentally, it squelches an "empty if body" warning from gcc. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* git-diff: resurrect the traditional empty "diff --git" behaviourJunio C Hamano2007-08-31
| | | | | | | | | | | | | | | | | | | | | | | | | The warning message to suggest "Consider running git-status" from "git-diff" that we experimented with during the 1.5.3 cycle turns out to be a bad idea. 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.

* git-diff: squelch "empty" diffsJunio C Hamano2007-08-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | After starting to edit a working tree file but later when your edit ends up identical to the original (this can also happen when you ran a wholesale regexp replace with something like "perl -i" that does not actually modify many of the paths), "git diff" between the index and the working tree outputs many "empty" diffs that show "diff --git" headers and nothing else, because these paths are stat-dirty. 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. Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | As Wincent Colaiuta found out, it's a bit unexpected for git diff to start a pager even when the --quiet option is specified. The problem is that the pager hides the return code -- which is the only output we're interested in in this case.

Fixed the cast in the latter hunk to combine-diff.c which was wrong in the original. Also converted ones left-over in combine-diff.c, diff-lib.c and upload-pack.c ] Signed-off-by: Shawn O.

| | | | | | | | | | | | | Introduces global inline: hashcmp(const unsigned char *sha1, const unsigned char *sha2) Uses memcmp for comparison and returns the result based on the length of the hash name (a future runtime decision).
