2019-10-04fast-export: add support for --import-marks-if-existsLibravatar Elijah Newren1-4/+19
fast-import has support for both an --import-marks flag and an --import-marks-if-exists flag; the latter of which will not die() if the file does not exist. fast-export only had support for an --import-marks flag; add an --import-marks-if-exists flag for consistency.

2019-09-28fast-export: fix exporting a tag and nothing elseLibravatar Elijah Newren1-1/+6
fast-export allows specifying revision ranges, which can be used to export a tag without exporting the commit it tags. fast-export handled this rather poorly: it would emit a "from :0" directive. Since marks start at 1 and increase, this means it refers to an unknown commit and fast-import will choke on the input. When we are unable to look up a mark for the object being tagged, use a "from $HASH" directive instead to fix this problem. Note that this is quite similar to the behavior fast-export exhibits with commits and parents when --reference-excluded-parents is passed along with an excluded commit range. For tags of excluded commits we do not require the --reference-excluded-parents flag because we always have to tag something. By contrast, when dealing with commits, pruning a parent is always a viable option, so we need the flag to specify that parent pruning is not wanted. (It is slightly weird that --reference-excluded-parents isn't the default with a separate --prune-excluded-parents flag, but backward compatibility concerns resulted in the current defaults.)

The core.untrackedCache config setting is slightly complicated, so clarify its use and centralize its parsing into the repo settings. The default value is "keep" (returned as -1), which persists the untracked cache if it exists. If the value is set as "false" (returned as 0), then remove the untracked cache if it exists. If the value is set as "true" (returned as 1), then write the untracked cache and persist it. Instead of relying on magic values of -1, 0, and 1, split these options into an enum. This allows the use of "-1" as a default value. After parsing the config options, if the value is unset we can initialize it to UNTRACKED_CACHE_KEEP.

2019-08-13packfile: drop release_pack_memory()Libravatar Jeff King1-11/+0
Long ago, in 97bfeb34df (Release pack windows before reporting out of memory., 2006-12-24), we taught xmalloc() and friends to try unmapping pack windows when malloc() failed. It's unlikely that his helps a lot in practice, and it has some downsides. First, the downsides: 1. It makes xmalloc() not thread-safe. We've worked around this in pack-objects.c, which installs its own locking version of the try_to_free_routine(). But other threaded code doesn't. 2. It makes the system as a whole harder to reason about. Functions which allocate heap memory under the hood may have farther-reaching effects than expected. That might be worth the tradeoff if there's a benefit. But in practice, it seems unlikely. We're generally dealing with mmap'd files, so the OS is going to do a much better job at responding to memory pressure by dropping individual pages (the exception is systems with NO_MMAP, but even there the OS can probably respond just as well with swapping). So the only thing we're really freeing is address space. On 64-bit systems, we have plenty of that to go around. On 32-bit systems, it could possibly help. But around the same time we made two other changes: 77ccc5bbd1 (Introduce new config option for mmap limit., 2006-12-23) and 60bb8b1453 (Fully activate the sliding window pack access., 2006-12-23). Together that means that a 32-bit system should have no more than 256MB total of packed-git mmaps at one time, split between a few 32MB windows. It's unlikely we have any address space problems since then, but we don't have any data since the features were all added at the same time. Likewise, xmmap() will try to free memory. At first glance, it seems like we'd need this (when we try to mmap a new window, we might need to close an old one to save address space on a 32-bit system). But we're saved again by core.packedGitLimit: if we're going to exceed our 256MB limit, we'll close an existing window before we even call mmap(). So it seems unlikely that this feature is actually doing anything useful. And while we don't have reports of it harming anything (probably because it rarely if ever kicks in), it would be nice to simplify the system overall. This patch drops the whole try_to_free system from xmalloc(), as well as the manual pack memory release in xmmap().

Note that it should only return with error when encountering an invalid commit object id coming from standard input. However, '--reachable' uses the same code path to process object ids pointed to by all refs, and that includes tag object ids as well, which should still be skipped over.

2019-08-02checkout.c: unstage empty deleted ita filesLibravatar Varun Naik1-0/+1
It is possible to delete a committed file from the index and then add it as intent-to-add. After `git checkout HEAD <pathspec>`, the file should be identical in the index and HEAD. The command already works correctly if the file has contents in HEAD. This patch provides the desired behavior even when the file is empty in HEAD. `git checkout HEAD <pathspec>` calls tree.c:read_tree_1(), with fn pointing to checkout.c:update_some(). update_some() creates a new cache entry but discards it when its mode and oid match those of the old entry. A cache entry for an ita file and a cache entry for an empty file have the same oid. Therefore, an empty deleted ita file previously passed both of these checks, and the new entry was discarded, so the file remained unchanged in the index. After this fix, if the file is marked as ita in the cache, then we avoid discarding the new entry and add the new entry to the cache instead. This change should not affect newly added ita files. For those, inside tree.c:read_tree_1(), tree_entry_interesting() returns entry_not_interesting, so fn is never called.

2019-07-31tree-walk: drop oid from traverse_infoLibravatar Jeff King1-1/+1
As the previous commit shows, the presence of an oid in each level of the traverse_info is confusing and ultimately not necessary. Let's drop it to make it clear that it will not always be set (as well as convince us that it's unused, and let the compiler catch any merges with other branches that do add new uses). Since the oid is part of name_entry, we'll actually stop embedding a name_entry entirely, and instead just separately hold the pathname, its length, and the mode. This makes the resulting code slightly more verbose as we have to pass those elements around individually. But it also makes it more clear what each code path is going to use (and in most of the paths, we really only care about the pathname itself). A few of these conversions are noisier than they need to be, as they also take the opportunity to rename "len" to "namelen" for clarity (especially where we also have "pathlen" or "ce_len" alongside).

2019-07-31setup_traverse_info(): stop copying oidLibravatar Jeff King1-1/+1
We assume that if setup_traverse_info() is passed a non-empty "base" string, that string is pointing into a tree object and we can read the object oid by skipping past the trailing NUL. As it turns out, this is not true for either of the two calls, and we may end up reading garbage bytes: 1. In git-merge-tree, our base string is either empty (in which case we'd never run this code), or it comes from our traverse_path() helper. The latter overallocates a buffer by the_hash_algo->rawsz bytes, but then fills it with only make_traverse_path(), leaving those extra bytes uninitialized (but part of a legitimate heap buffer). 2. In unpack_trees(), we pass o->prefix, which is some arbitrary string from the caller. In "git read-tree --prefix=foo", for instance, it will point to the command-line parameter, and we'll read 20 bytes past the end of the string. Interestingly, tools like ASan do not detect (2) because the process argv is part of a big pre-allocated buffer. So we're reading trash, but it's trash that's probably part of the next argument, or the environment. You can convince it to fail by putting something like this at the beginning of common-main.c's main() function: { int i; for (i = 0; i < argc; i++) argv[i] = xstrdup_or_null(argv[i]); } That puts the arguments into their own heap buffers, so running: make SANITIZE=address test will find problems when "read-tree --prefix" is used (e.g., in t3030). Doubly interesting, even with the hackery above, this does not fail prior to ea82b2a085 (tree-walk: store object_id in a separate member, 2019-01-15). That commit switched setup_traverse_info() to actually copying the hash, rather than simply pointing to it. That pointer was always pointing to garbage memory, but that commit started actually dereferencing the bytes, which is what triggers ASan. That also implies that nobody actually cares about reading these oid bytes anyway (or at least no path covered by our tests). And manual inspection of the code backs that up (I'll follow this patch with some cleanups that show definitively this is the case, but they're quite invasive, so it's worth doing this fix on its own). So let's drop the bogus hashcpy(), along with the confusing oversizing in merge-tree. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-07-31repack: simplify handling of auto-bitmaps and .keep filesLibravatar Jeff King1-15/+2
Commit 7328482253 (repack: disable bitmaps-by-default if .keep files exist, 2019-06-29) taught repack to prefer disabling bitmaps to duplicating objects (unless bitmaps were asked for explicitly). But there's an easier way to do this: if we keep passing the --honor-pack-keep flag to pack-objects when auto-enabling bitmaps, then pack-objects already makes the same decision (it will disable bitmaps rather than duplicate). Better still, pack-objects can actually decide to do so based not just on the presence of a .keep file, but on whether that .keep file actually impacts the new pack we're making (so if we're racing with a push or fetch, for example, their temporary .keep file will not block us from generating bitmaps if they haven't yet updated their refs). And because repack uses the --write-bitmap-index-quiet flag, we don't have to worry about pack-objects generating confusing warnings when it does see a .keep file. We can confirm this by tweaking the .keep test to check repack's stderr. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-07-31repack: silence warnings when auto-enabled bitmaps cannot be builtLibravatar Jeff King2-11/+25
Depending on various config options, a full repack may not be able to build a reachability bitmap index (e.g., if pack.packSizeLimit forces us to write multiple packs). In these cases pack-objects may write a warning to stderr. Since 36eba0323d (repack: enable bitmaps by default on bare repos, 2019-03-14), we may generate these warnings even when the user did not explicitly ask for bitmaps. This has two downsides: - it can be confusing, if they don't know what bitmaps are - a daemonized auto-gc will write this to its log file, and the presence of the warning may suppress further auto-gc (until gc.logExpiry has elapsed) Let's have repack communicate to pack-objects that the choice to turn on bitmaps was not made explicitly by the user, which in turn allows pack-objects to suppress these warnings.

2019-07-31rebase -r: do not (re-)generate root commits with `--root` *and* `--onto`Libravatar Johannes Schindelin1-2/+5
When rebasing a complete commit history onto a given commit, it is pretty obvious that the root commits should be rebased on top of said given commit. To test this, let's kill two birds with one stone and add a test case to t3427-rebase-subtree.sh that not only demonstrates that this works, but also that `git rebase -r` works with merge strategies now.

2019-07-31rebase -r: support merge strategies other than `recursive`Libravatar Johannes Schindelin1-9/+0
We already support merge strategies in the sequencer, but only for `pick` commands. With this commit, we now also support them in `merge` commands. The approach is simple: if any merge strategy option is specified, or if any merge strategy other than `recursive` is specified, we simply spawn the `git merge` command. Otherwise, we handle the merge in-process just as before. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-07-31rebase: fold git-rebase--common into the -p backendLibravatar Johannes Schindelin1-2/+1
The only remaining scripted part of `git rebase` is the `--preserve-merges` backend. Meaning: there is little reason to keep the "library of common rebase functions" as a separate file. While moving the functions to `git-rebase--preserve-merges.sh`, we also drop the `move_to_original_branch` function that is no longer used.

2019-07-31Drop unused git-rebase--am.shLibravatar Johannes Schindelin1-4/+0
Since 21853626ea (built-in rebase: call `git am` directly, 2019-01-18), the built-in rebase already uses the built-in `git am` directly. Now that d03ebd411c (rebase: remove the rebase.useBuiltin setting, 2019-03-18) even removed the scripted rebase, there is no longer any user of `git-rebase--am.sh`, so let's just remove it.

2019-07-30grep: fix worktree case in submodulesLibravatar Matheus Tavares1-4/+6
Running git-grep with --recurse-submodules results in a cached grep for the submodules even when --cached is not used. This makes all modifications in submodules' tracked files be always ignored when grepping. Solve that making git-grep respect the cached option when invoking grep_cache() inside grep_submodule(). Also, add tests to ensure that the desired behavior is performed.
