Traditionally a submodule is comprised of a gitlink as well as a corresponding entry in the .gitmodules file. Diff doesn't follow this paradigm as its config callback routine falls back to populating the submodule-config if a config entry starts with 'submodule.'. Remove this behavior in order to be consistent with how the submodule-config is populated, via calling 'gitmodules_config()' or 'repo_read_gitmodules()'.

xfopen() - provides error details - explains error on reading, or writing, or whatever operation - has l10n support - prints file name in the error Some of these are missing in the places that are replaced with xfopen(), which is a clear win. In some other places, it's just less code (not as clearly a win as the previous case but still is). The only slight regresssion is in remote-testsvn, where we don't report the file class (marks files) in the error messages anymore.

The feature was included in v2.11 (released 2016-11-29) and we got no negative feedback. Quite the opposite, all feedback we got was positive. Turn it on by default. Users who dislike the feature can turn it off by setting diff.indentHeuristic (which also configures plumbing commands, see prior patches). The change to t/t4051-diff-function-context.sh is needed because the heuristic shifts the changed hunk in the patch. To get the same result regardless of the heuristic configuration, we modify the test file differently: We insert a completely new line after line 2, instead of simply duplicating it.

This heuristic was originally introduced as an experimental feature, and therefore part of the UI configuration. But the user often sees diffs generated by plumbing commands like diff-tree. Moving the indent heuristic into diff's basic configuration prepares the way for diff plumbing commands to respect the setting. The heuristic itself merely makes the diffs more aesthetically pleasing, without changing their correctness. Scripts that rely on the diff plumbing commands should not care whether or not the heuristic is employed.

To generate a patch id, we format the diff header into a fixed-size buffer, and then feed the result to our sha1 computation. The fixed buffer has size '4*PATH_MAX + 20', which in theory accommodates the four filenames plus some extra data. Except: 1. The filenames may not be constrained to PATH_MAX. The static value may not be a real limit on the current filesystem. Moreover, we may compute patch-ids for names stored only in git, without touching the current filesystem at all. 2. The 20 bytes is not nearly enough to cover the extra content we put in the buffer. As a result, the data we feed to the sha1 computation may be truncated, and it's possible that a commit with a very long filename could erroneously collide in the patch-id space with another commit. For instance, if one commit modified "really-long-filename/foo" and another modified "bar" in the same directory. In practice this is unlikely. Because the filenames are repeated, and because there's a single cutoff at the end of the buffer, the offending filename would have to be on the order of four times larger than PATH_MAX. We could fix this by moving to a strbuf. However, we can observe that the purpose of formatting this in the first place is to feed it to git_SHA1_Update(). So instead, let's just feed each part of the formatted string directly. This actually ends up more readable, and we can even factor out some duplicated bits from the various conditional branches. Technically this may change the output of patch-id for very long filenames, but it's not worth making an exception for this in the --stable output. It was a bug, and one that only affected an unlikely set of paths. And anyway, the exact value would have varied from platform to platform depending on the value of PATH_MAX, so there is no "stable" value.

Since we will likely be introducing a new hash function at some point, and that hash function might be longer than 40 hex characters, use the constant GIT_MAX_HEXSZ, which is designed to be suitable for allocations, instead of GIT_SHA1_HEXSZ. This will ease the transition down the line by distinguishing between places where we need to allocate memory suitable for the largest hash from those where we need to handle the current hash.

The prefix_filename() function returns a pointer to static storage, which makes it easy to use dangerously. We already fixed one buggy caller in hash-object recently, and the calls in apply.c are suspicious (I didn't dig in enough to confirm that there is a bug, but we call the function once in apply_all_patches() and then again indirectly from parse_chunk()). Let's make it harder to get wrong by allocating the return value. For simplicity, we'll do this even when the prefix is empty (and we could just return the original file pointer). That will cause us to allocate sometimes when we wouldn't otherwise need to, but this function isn't called in performance critical code-paths (and it already _might_ allocate on any given call, so a caller that cares about performance is questionable anyway). The downside is that the callers need to remember to free() the result to avoid leaking. Most of them already used xstrdup() on the result, so we know they are OK. The remainder have been converted to use free() as appropriate. I considered retaining a prefix_filename_unsafe() for cases where we know the static lifetime is OK (and handling the cleanup is awkward). This is only a handful of cases, though, and it's not worth the mental energy in worrying about whether the "unsafe" variant is OK to use in any situation.

This function takes the prefix as a ptr/len pair, but in every caller the length is exactly strlen(ptr). Let's simplify the interface and just take the string. This saves callers specifying it (and in some cases handling a NULL prefix). In a handful of cases we had the length already without calling strlen, so this is technically slower. But it's not likely to matter (after all, if the prefix is non-empty we'll allocate and copy it into a buffer anyway).

Callers of diff_populate_filespec() can choose to ask only for the size of the blob without grabbing the blob data, and the function, after running lstat() when the filespec points at a working tree file, returns by copying the value in size field of the stat structure into the size field of the filespec when this is the case. However, this short-cut cannot be taken if the contents from the path needs to go through convert_to_git(), whose resulting real blob data may be different from what is in the working tree file. As "git diff --quiet" compares the .size fields of filespec structures to skip content comparison, this bug manifests as a false "there are differences" for a file that needs eol conversion, for example.

If you run "git log --graph --name-only", the pathnames are not indented to go along with their matching commits (unlike all of the other diff formats). We need to output the line prefix for each item before writing it. The tests cover both --name-status and --name-only. The former actually gets this right already, because it builds on the --raw format functions. It's only --name-only which uses its own code (and this fix mirrors the code in diff_flush_raw()). Note that the tests don't follow our usual style of setting up the "expect" output inside the test block. This matches the surrounding style, but more importantly it is easier to read: we don't have to worry about embedded single-quotes, and the leading indentation is more obvious.

Use the macro SWAP to exchange the value of pairs of variables instead of swapping them manually with the help of a temporary variable. The resulting code is shorter and easier to read. The two cases were not transformed by the semantic patch swap.cocci because it's extra careful and handles only cases where the types of all variables are the same -- and here we swap two ints and use an unsigned temporary variable for that. Nevertheless the conversion is safe, as the value range is preserved with and without the patch. Signed-off-by: NRene Scharfe <l.s.r@web.de> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

When a patch inserts a block of lines, whose last lines are the same as the existing lines that appear before the inserted block, "git diff" can choose any place between these existing lines as the boundary between the pre-context and the added lines (adjusting the end of the inserted block as appropriate) to come up with variants of the same patch, and some variants are easier to read than others. We have been trying to improve the choice of this boundary, and Git 2.11 shipped with an experimental "compaction-heuristic". Since then another attempt to improve the logic further resulted in a new "indent-heuristic" logic. It is agreed that the latter gives better result overall, and the former outlived its usefulness. Retire "compaction", and keep "indent" as an experimental feature. The latter hopefully will be turned on by default in a future release, but that should be done as a separate step.

There are two different places where the --no-abbrev option is parsed, and two different places where SHA-1s are abbreviated. We normally parse --no-abbrev with setup_revisions(), but in the no-index case, "git diff" calls diff_opt_parse() directly, and diff_opt_parse() didn't handle --no-abbrev until now. (It did handle --abbrev, however.) We normally abbreviate SHA-1s with find_unique_abbrev(), but commit 4f03666a ("diff: handle sha1 abbreviations outside of repository, 2016-10-20) recently introduced a special case when you run "git diff" outside of a repository. setup_revisions() does also call diff_opt_parse(), but not for --abbrev or --no-abbrev, which it handles itself. setup_revisions() sets rev_info->abbrev, and later copies that to diff_options->abbrev. It handles --no-abbrev by setting abbrev to zero. (This change doesn't touch that.) Setting abbrev to zero was broken in the outside-of-a-repository special case, which until now resulted in a truly zero-length SHA-1, rather than taking zero to mean do not abbreviate. The only way to trigger this bug, however, was by running "git diff --raw" without either the --abbrev or --no-abbrev options, because 1) without --raw it doesn't respect abbrev (which is bizarre, but has been that way forever), 2) we silently clamp --abbrev=0 to MINIMUM_ABBREV, and 3) --no-abbrev wasn't handled until now. The outside-of-a-repository case is one of three no-index cases. The other two are when one of the files you're comparing is outside of the repository you're in, and the --no-index option.

When generating diffs outside a repository (e.g., with "diff --no-index"), we may write abbreviated sha1s as part of "--raw" output or the "index" lines of "--patch" output. Since we have no object database, we never find any collisions, and these sha1s get whatever static abbreviation length is configured (typically 7). However, we do blindly look in ".git/objects" to see if any objects exist, even though we know we are not in a repository. This is usually harmless because such a directory is unlikely to exist, but could be wrong in rare circumstances. Let's instead notice when we are not in a repository and behave as if the object database is empty (i.e., just use the default abbrev length). It would perhaps make sense to be conservative and show full sha1s in that case, but showing the default abbreviation is what we've always done (and is certainly less ugly). Note that this does mean that: cd /not/a/repo GIT_OBJECT_DIRECTORY=/some/real/objdir git diff --no-index ... used to look for collisions in /some/real/objdir but now does not. This could be considered either a bugfix (we do not look at objects if we have no repository) or a regression, but it seems unlikely that anybody would care much either way.

The code that sets custom abbreviation length, in response to command line argument, often does something like this: if (skip_prefix(arg, "--abbrev=", &arg)) abbrev = atoi(arg); else if (!strcmp("--abbrev", &arg)) abbrev = DEFAULT_ABBREV; /* make the value sane */ if (abbrev < 0 || 40 < abbrev) abbrev = ... some sane value ... However, it is pointless to sanity-check and tweak the value obtained from DEFAULT_ABBREV. We are going to allow it to be initially set to -1 to signal that the default abbreviation length must be auto sized upon the first request to abbreviate, based on the number of objects in the repository, and when that happens, rejecting or tweaking a negative value to a "saner" one will negatively interfere with the auto sizing. The codepaths for git rev-parse --short <object> git diff --raw --abbrev do exactly that; allow them to pass possibly negative abbrevs intact, that will come from DEFAULT_ABBREV in the future.
