* rerere: release lockfile in non-writing functionsJeff King2015-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a bug in builtin/am.c in which we take a lock on MERGE_RR recursively. But rather than fix am.c, this patch fixes the confusing interface from rerere.c that caused the bug. Read on for the gory details. The setup_rerere() function both reads the existing MERGE_RR file, and takes MERGE_RR.lock. In the rerere() and rerere_forget() functions, we end up in write_rr(), which will then commit the lock file. But for functions like rerere_clear() that do not write to MERGE_RR, we expect the caller to have handled setup_rerere(). That caller would then need to release the lockfile, but it can't; the lock struct is local to rerere.c. For builtin/rerere.c, this is OK. We run a single rerere operation and then exit immediately, which has the side effect of rolling back the lockfile. But in builtin/am.c, this is actively wrong. If we run "git am -3 --skip", we call setup-rerere twice without releasing the lock: 1. The "--skip" causes us to call am_rerere_clear(), which calls setup_rerere(), but never drops the lock. 2. We then proceed to the next patch. 3. The "--3way" may cause us to call rerere() to handle conflicts in that patch, but we are already holding the lock. The lockfile code dies with: BUG: prepare_tempfile_object called for active object We could fix this by having rerere_clear() call rollback_lock_file(). But it feels a bit odd for it to roll back a lockfile that it did not itself take. So let's simplify the interface further, and handle setup_rerere in the function itself, taking away the question from the caller over whether they need to do so. We can give rerere_gc() the same treatment, as well (even though it doesn't have any callers besides builtin/rerere.c at this point). Note that these functions don't take flags from their callers to pass along to setup_rerere; that's OK, because the flags would not be meaningful for what they are doing. Both of those functions need to hold the lock because even though they do not write to MERGE_RR, they are still writing and should be protected from a simultaneous "rerere" run. But rerere_remaining(), "rerere diff", and "rerere status" are all read-only operations. They want to setup_rerere(), but do not care about taking the lock in the first place. Since our update of MERGE_RR is the usual atomic rename done by commit_lock_file, they can just do a lockless read. For that, we teach setup_rerere a READONLY flag to avoid the lock. As a bonus, this pushes builtin/rerere.c's setup_rerere call closer to the functions that use it. Which means that "git rerere totally-bogus-command" will no longer silently exit(0) in a repository without rerere enabled.

* memoize common git-path "constant" filesJeff King2015-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the most common uses of git_path() is to pass a constant, like git_path("MERGE_MSG"). This has two drawbacks: 1. The return value is a static buffer, and the lifetime is dependent on other calls to git_path, etc. 2. There's no compile-time checking of the pathname. This is OK for a one-off (after all, we have to spell it correctly at least once), but many of these constant strings appear throughout the code. This patch introduces a series of functions to "memoize" these strings, which are essentially globals for the lifetime of the program. We compute the value once, take ownership of the buffer, and return the cached value for subsequent calls. cache.h provides a helper macro for defining these functions as one-liners, and defines a few common ones for global use. Using a macro is a little bit gross, but it does nicely document the purpose of the functions. If we need to touch them all later (e.g., because we learned how to change the git_dir variable at runtime, and need to invalidate all of the stored values), it will be much easier to have the complete list. Note that the shared-global functions have separate, manual declarations. We could do something clever with the macros (e.g., expand it to a declaration in some places, and a declaration _and_ a definition in path.c). But there aren't that many, and it's probably better to stay away from too-magical macros. Likewise, if we abandon the C preprocessor in favor of generating these with a script, we could get much fancier. E.g., normalizing "FOO/BAR-BAZ" into "git_path_foo_bar_baz". But the small amount of saved typing is probably not worth the resulting confusion to readers who want to grep for the function's definition.

* pathspec: pass directory indicator to match_pathspec_item()Nguyễn Thái Ngọc Duy2014-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | This patch activates the DO_MATCH_DIRECTORY code in m_p_i(), which makes "git diff HEAD submodule/" and "git diff HEAD submodule" produce the same output. Previously only the version without trailing slash returns the difference (if any). That's the effect of new ce_path_match(). dir_path_match() is not executed by the new tests. And it should not introduce regressions. Previously if path "dir/" is passed in with pathspec "dir/", they obviously match. With new dir_path_match(), the path becomes _directory_ "dir" vs pathspec "dir/", which is not executed by the old code path in m_p_i(). The new code path is executed and produces the same result. The other case is pathspec "dir" and path "dir/" is now turned to "dir" (with DO_MATCH_DIRECTORY). Still the same result before or after the patch. So why change?

* | Convert "struct cache_entry *" to "const ..." wherever possibleNguyễn Thái Ngọc Duy2013-07-09
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I attempted to make index_state->cache[] a "const struct cache_entry **" to find out how existing entries in index are modified and where. The question I have is what do we do if we really need to keep track of on-disk changes in the index. The result is - diff-lib.c: setting CE_UPTODATE - name-hash.c: setting CE_HASHED - preload-index.c, read-cache.c, unpack-trees.c and builtin/update-index: obvious - entry.c: write_entry() may refresh the checked out entry via fill_stat_cache_info(). This causes "non-const struct cache_entry *" in builtin/apply.c, builtin/checkout-index.c and builtin/checkout.c - builtin/ls-files.c: --with-tree changes stagemask and may set CE_UPDATE Of these, write_entry() and its call sites are probably most interesting because it modifies on-disk info. But this is stat info and can be retrieved via refresh, at least for porcelain commands. Other just uses ce_flags for local purposes. So, keeping track of "dirty" entries is just a matter of setting a flag in index modification functions exposed by read-cache.c. Except unpack-trees, the rest of the code base does not do anything funny behind read-cache's back. The actual patch is less valueable than the summary above. But if anyone wants to re-identify the above sites. Applying this patch, then this: diff --git a/cache.h b/cache.h index 430d021..1692891 100644 --- a/cache.h +++ b/cache.h @@ -267,7 +267,7 @@ static inline unsigned int canon_mode(unsigned int mode) #define cache_entry_size(len) (offsetof(struct cache_entry,name) + (len) + 1) struct index_state { - struct cache_entry **cache; + const struct cache_entry **cache; unsigned int version; unsigned int cache_nr, cache_alloc, cache_changed; struct string_list *resolve_undo; will help quickly identify them without bogus warnings.

* rerere forget: do not segfault if not all stages are presentJohannes Sixt2013-04-04
| | | | | | | | | | | | | | | | | | | | The loop that fills in the buffers that are later passed to the merge driver exits early when not all stages of a path are present in the index. But since the buffer pointers are not initialized in advance, the subsequent accesses are undefined. Initialize buffer pointers in advance to avoid undefined behavior later. That is not sufficient, though, to get correct operation of handle_cache(). The function replays a conflicted merge to extract the part inside the conflict markers. As written, the loop exits early when a stage is missing. Consequently, the buffers for later stages that would be present in the index are not filled in and the merge is replayed with incomplete data. Fix it by investigating all stages of the given path.

When rerere.enabled is set in the original repository, but the user has not encountered any conflicts yet, the original repository may not yet have .git/rr-cache directory. When rerere wants to run in a new work tree created from such a young original repository, it fails to mkdir(2) .git/rr-cache that is a symlink to a yet-to-be-created directory. There are three possible approaches to this: - A naive solution is not to create a symlink in the git-new-workdir script to a directory the original does not have (yet). This is not a solution, as we tend to lazily create subdirectories of .git/, and having rerere.enabled configuration set is a strong indication that the user _wants_ to have this lazy creation to happen; - We could always create .git/rr-cache upon repository creation. This is tempting but will not help people with existing repositories. - Detect this case by seeing that mkdir(2) failed with EEXIST, checking that the path is a symlink, and try running mkdir(2) on the link target. This patch solves the issue by doing the third one. Strictly speaking, this is incomplete. It does not attempt to handle relative symbolic link that points into the original repository, but this is good enough to help people who use contrib/workdir/git-new-workdir script.

When the user wants a list of paths that need hand-resolving, output from "rerere status" does not help, as it shows only the second category, but the paths in the third category still needs work (rerere only makes sense for regular files that have both our side and their side, and does not help other kinds of conflicts, e.g. "we modified, they deleted"). The new subcommand "rerere remaining" can be used to show both. As opposed to "rerere status", this subcommand also skips printing paths that have been added to the index, since these paths are already resolved and are no longer "remaining".

After an unsuccessful merge, rerere records conflict hunks from the work tree under .git/rr-cache. If the merge was performed with merge.renormalize enabled, both sides of the conflict hunk use the current work tree’s end-of-line and smudge rules; there is not really much of a choice. After a successful manual resolution, rerere records the postimage. Here, also, the file will be in the current work tree’s canonical format and there is not much to do about it. When encountering that conflict again, merge looks up the preimage and postimage using the conflict hunk as a key and runs a three-way merge to apply that resolution to the work tree. Since the conflict hunk used the current work tree’s canonical format, chances are the version in the work tree, the preimage, and the postimage will, too. In fact using the merge.renormalize machinery is exactly the wrong thing to do, since its result has been run through convert_to_git and therefore is not suitable for writing to the work tree. The only affected caller is "git merge".

This can cause the loss of frequently used conflict resolutions (e.g. long-living topic branches are merged into a regularly rebuilt integration branch (think of git's pu)) when they become old enough to exceed 'rerere gc's threshold. To prevent the loss of valuable merge resolutions 'rerere' will (1) update the timestamp of the recorded conflict resolution (i.e. 'postimage') each time when encountering and resolving the same merge conflict, and (2) take this timestamp, i.e. the time of the last usage into account when gc'ing.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this patch at least IBM VisualAge C 5.0 (I have 5.0.2) on AIX 5.1 fails to compile git. enum style is inconsistent already, with some enums declared on one line, some over 3 lines with the enum values all on the middle line, sometimes with 1 enum value per line... and independently of that the trailing comma is sometimes present and other times absent, often mixing with/without trailing comma styles in a single file, and sometimes in consecutive enum declarations. Clearly, omitting the comma is the more portable style, and this patch changes all enum declarations to use the portable omitted dangling comma style consistently. Signed-off-by: Gary V.

* | ll_merge(): add ancestor label parameter for diff3-style outputJonathan Nieder2010-03-20
|/ | | | | | | | | | | | | | | | Commands using the ll_merge() function will present conflict hunks imitating ‘diff3 -m’ output if the merge.conflictstyle configuration option is set appropriately. Unlike ‘diff3 -m’, the output does not include a label for the merge base on the ||||||| line of the output, and some tools misparse the conflict hunks without that. Add a new ancestor_label parameter to ll_merge() to give callers the power to rectify this situation. If ancestor_label is NULL, the output format is unchanged. All callers pass NULL for now.
