2019-08-13worktree remove: clarify error message on dirty worktreeSZEDER Gábor
To avoid data loss, 'git worktree remove' refuses to delete a worktree if it's dirty or contains untracked files. However, the error message only mentions that the worktree "is dirty", even if the worktree in question is in fact clean, but contains untracked files: $ git worktree add test-worktree Preparing worktree (new branch 'test-worktree') HEAD is now at aa53e60 Initial $ >test-worktree/untracked-file $ git worktree remove test-worktree/ fatal: 'test-worktree/' is dirty, use --force to delete it $ git -C test-worktree/ diff $ git -C test-worktree/ diff --cached $ # Huh? Where are those dirty files?! Clarify this error message to say that the worktree "contains modified or untracked files".

2019-08-05commit-graph: error out on invalid commit oids in 'write --stdin-commits'SZEDER Gábor
While 'git commit-graph write --stdin-commits' expects commit object ids as input, it accepts and silently skips over any invalid commit object ids, and still exits with success: # nonsense $ echo not-a-commit-oid | git commit-graph write --stdin-commits $ echo $? 0 # sometimes I forgot that refs are not good... $ echo HEAD | git commit-graph write --stdin-commits $ echo $? 0 # valid tree OID, but not a commit OID $ git rev-parse HEAD^{tree} | git commit-graph write --stdin-commits $ echo $? 0 $ ls -l .git/objects/info/commit-graph ls: cannot access '.git/objects/info/commit-graph': No such file or directory Check that all input records are indeed valid commit object ids and return with error otherwise, the same way '--stdin-packs' handles invalid input; see e103f7276f (commit-graph: return with errors during write, 2019-06-12). 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. Therefore add a new flag to 'enum commit_graph_write_flags' and a corresponding field to 'struct write_commit_graph_context', so we can differentiate between those two cases.

2019-08-02checkout.c: unstage empty deleted ita filesVarun Naik
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.

2019-08-01tree-walk: add a strbuf wrapper for make_traverse_path()Jeff King
All but one of the callers of make_traverse_path() allocate a new heap buffer to store the path. Let's give them an easy way to write to a strbuf, which saves them from computing the length themselves (which is especially tricky when they want to add to the path). It will also make it easier for us to change the make_traverse_path() interface in a future patch to improve its bounds-checking.

2019-07-31tree-walk: drop oid from traverse_infoJeff King
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 oidJeff King
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 filesJeff King
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 builtJeff King
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.
