2021-04-12pack-objects: update "nr_seen" progress based on pack-reused countLibravatar Jeff King1-1/+2
When serving a clone or fetch with bitmaps, after deciding which objects need to be sent our "pack reuse" mechanism kicks in: we try to send more-or-less verbatim a bunch of objects from the beginning of the bitmapped packfile without even adding them to the to_pack.objects array. After deciding which objects will be in the "reused" portion, we update nr_result to account for those, and then trigger display_progress() to show the user (who is undoubtedly dazzled that we managed to enumerate so many objects so quickly). But then something confusing happens: the "Enumerating objects" progress meter jumps _backwards_, counting up from zero the number of objects we actually add into to_pack.objects. This worked correctly once upon a time, but was broken in 5af050437a (pack-objects: show some progress when counting kept objects, 2018-04-15), when the latter half of that progress meter switched to using a separate nr_seen counter, rather than nr_result. Nobody noticed for two reasons: - prior to the pack-reuse fixes from a14aebeac3 (Merge branch 'jk/packfile-reuse-cleanup', 2020-02-14), the reuse code almost never kicked in anyway - the output looks _kind of_ correct. The "backwards" moment is hard to catch, because we overwrite the old progress number with the new one, and the larger number is displayed only for a second. So unless you look at that exact second, you just see the much smaller value, counting up to the number of non-reused objects (though of course if you catch it in stderr, or look at GIT_TRACE_PACKET from a server with bitmaps, you can see both values). This smaller output isn't wrong per se, but isn't counting what we ever intended to. We should give the user the whole number of objects we considered (which, as per 5af050437a's original purpose, is already _not_ a count of what goes into to_pack.objects). The follow-on "Counting objects" meter shows the actual number of objects we feed into that array. We can easily fix this by bumping (and showing) nr_seen for the pack-reused objects. When the included test is run without this patch, the second pack-objects invocation produces "Enumerating objects: 1" to show the one loose object, even though the resulting pack has hundreds of objects in it. With it, we jump to "Enumerating objects: 674" after deciding on reuse, and then "675" when we add in the loose object.

2021-04-01midx: allow marking a pack as preferredLibravatar Taylor Blau2-4/+17
When multiple packs in the multi-pack index contain the same object, the MIDX machinery must make a choice about which pack it associates with that object. Prior to this patch, the lowest-ordered[1] pack was always selected. Pack selection for duplicate objects is relatively unimportant today, but it will become important for multi-pack bitmaps. This is because we can only invoke the pack-reuse mechanism when all of the bits for reused objects come from the reuse pack (in order to ensure that all reused deltas can find their base objects in the same pack). To encourage the pack selection process to prefer one pack over another (the pack to be preferred is the one a caller would like to later use as a reuse pack), introduce the concept of a "preferred pack". When provided, the MIDX code will always prefer an object found in a preferred pack over any other. No format changes are required to store the preferred pack, since it will be able to be inferred with a corresponding MIDX bitmap, by looking up the pack associated with the object in the first bit position (this ordering is described in detail in a subsequent commit). [1]: the ordering is specified by MIDX internals; for our purposes we can consider the "lowest ordered" pack to be "the one with the most-recent mtime.

2021-04-01builtin/clone.c: add --reject-shallow optionLibravatar Li Linchao1-0/+21
In some scenarios, users may want more history than the repository offered for cloning, which happens to be a shallow repository, can give them. But because users don't know it is a shallow repository until they download it to local, we may want to refuse to clone this kind of repository, without creating any unnecessary files. The '--depth=x' option cannot be used as a solution; the source may be deep enough to give us 'x' commits when cloned, but the user may later need to deepen the history to arbitrary depth. Teach '--reject-shallow' option to "git clone" to abort as soon as we find out that we are cloning from a shallow repository.

2021-03-31builtin/pack-objects.c: respect 'pack.preferBitmapTips'Libravatar Taylor Blau1-0/+34
When writing a new pack with a bitmap, it is sometimes convenient to indicate some reference prefixes which should receive priority when selecting which commits to receive bitmaps. A truly motivated caller could accomplish this by setting 'pack.islandCore', (since all commits in the core island are similarly marked as preferred) but this requires callers to opt into using delta islands, which they may or may not want to do. Introduce a new multi-valued configuration, 'pack.preferBitmapTips' to allow callers to specify a list of reference prefixes. All references which have a prefix contained in 'pack.preferBitmapTips' will mark their tips as "preferred" in the same way as commits are marked as preferred for selection by 'pack.islandCore'. The choice of the verb "prefer" is intentional: marking the NEEDS_BITMAP flag on an object does *not* guarantee that that object will receive a bitmap. It merely guarantees that that commit will receive a bitmap over any *other* commit in the same window by bitmap_writer_select_commits(). The test this patch adds reflects this quirk, too. It only tests that a commit (which didn't receive bitmaps by default) is selected for bitmaps after changing the value of 'pack.preferBitmapTips' to include it. Other commits may lose their bitmaps as a byproduct of how the selection process works (bitmap_writer_select_commits() ignores the remainder of a window after seeing a commit with the NEEDS_BITMAP flag). This configuration will aide in selecting important references for multi-pack bitmaps, since they do not respect the same pack.islandCore configuration. (They could, but doing so may be confusing, since it is packs--not bitmaps--which are influenced by the delta-islands configuration). In a fork network repository (one which lists all forks of a given repository as remotes), for example, it is useful to set pack.preferBitmapTips to 'refs/remotes/<root>/heads' and 'refs/remotes/<root>/tags', where '<root>' is an opaque identifier referring to the repository which is at the base of the fork chain.

2021-03-31sequencer: fix edit handling for cherry-pick and revert messagesLibravatar Elijah Newren1-3/+1
save_opts() should save any non-default values. It was intended to do this, but since most options in struct replay_opts default to 0, it only saved non-zero values. Unfortunately, this does not always work for options.edit. Roughly speaking, options.edit had a default value of 0 for cherry-pick but a default value of 1 for revert. Make save_opts() record a value whenever it differs from the default. options.edit was also overly simplistic; we had more than two cases. The behavior that previously existed was as follows: Non-conflict commits Right after Conflict revert Edit iff isatty(0) Edit (ignore isatty(0)) cherry-pick No edit See above Specify --edit Edit (ignore isatty(0)) See above Specify --no-edit (*) See above (*) Before stopping for conflicts, No edit is the behavior. After stopping for conflicts, the --no-edit flag is not saved so see the first two rows. However, the expected behavior is: Non-conflict commits Right after Conflict revert Edit iff isatty(0) Edit iff isatty(0) cherry-pick No edit Edit iff isatty(0) Specify --edit Edit (ignore isatty(0)) Edit (ignore isatty(0)) Specify --no-edit No edit No edit In order to get the expected behavior, we need to change options.edit to a tri-state: unspecified, false, or true. When specified, we follow what it says. When unspecified, we need to check whether the current commit being created is resolving a conflict as well as consulting options.action and isatty(0). While at it, add a should_edit() utility function that compresses options.edit down to a boolean based on the additional information for the non-conflict case. continue_single_pick() is the function responsible for resuming after conflict cases, regardless of whether there is one commit being picked or many. Make this function stop assuming edit behavior in all cases, so that it can correctly handle !isatty(0) and specific requests to not edit the commit message.

Handle sub-commands of the 'git multi-pack-index' builtin (e.g., "write", "repack", etc.) separately from one another. This allows sub-commands with unique options, without forcing cmd_multi_pack_index() to reject invalid combinations itself. This comes at the cost of some duplication and boilerplate. Luckily, the duplication is reduced to a minimum, since common options are shared among sub-commands due to a suggestion by Ævar. (Sub-commands do have to retain the common options, too, since this builtin accepts common options on either side of the sub-command). Roughly speaking, cmd_multi_pack_index() parses options (including common ones), and stops at the first non-option, which is the sub-command. It then dispatches to the appropriate sub-command, which parses the remaining options (also including common options). Unknown options are kept by the sub-commands in order to detect their presence (and complain that too many arguments were given).

Let's also replace register_found_gitmodules() with directly manipulating the "gitmodules_found" member. A recent commit moved it into "fsck_options" so we could do this here. I'm sticking this callback in fsck.c. Perhaps in the future we'd like to accumulate such callbacks into another file (maybe fsck-cb.c, similar to parse-options-cb.c?), but while we've got just the one let's just put it into fsck.c.

One might think that not setting up the error_func earlier means that we're relying on the "error_func" not being set in some code in between the two hunks being modified here. But we're not, all we're doing in the rest of "cmd_index_pack()" is further setup by calling fsck_set_msg_types(), and assigning to do_fsck_object.

Change the fsck_error callback to also pass along the fsck_msg_id. Before this change the only way to get the message id was to parse it back out of the "message". Let's pass it down explicitly for the benefit of callers that might want to use it, as discussed in [1]. Passing the msg_type is now redundant, as you can always get it back from the msg_id, but I'm not changing that convention. It's really common to need the msg_type, and the report() function itself (which calls "fsck_error") needs to call fsck_msg_type() to discover it.

Move the FSCK_{FATAL,INFO,ERROR,WARN,IGNORE} defines into a new fsck_msg_type enum. These defines were originally introduced in: - ba002f3b28a (builtin-fsck: move common object checking code to fsck.c, 2008-02-25) - f50c4407305 (fsck: disallow demoting grave fsck errors to warnings, 2015-06-22) - efaba7cc77f (fsck: optionally ignore specific fsck issues completely, 2015-06-22) - f27d05b1704 (fsck: allow upgrading fsck warnings to errors, 2015-06-22) The reason these were defined in two different places is because we use FSCK_{IGNORE,INFO,FATAL} only in fsck.c, but FSCK_{ERROR,WARN} are used by external callbacks. Untangling that would take some more work, since we expose the new "enum fsck_msg_type" to both. Similar to "enum object_type" it's not worth structuring the API in such a way that only those who need FSCK_{ERROR,WARN} pass around a different type.

2021-03-23rebase: remove transitory rebase.useBuiltin setting & envLibravatar Ævar Arnfjörð Bjarmason1-11/+0
Remove the rebase.useBuiltin setting and the now-obsolete GIT_TEST_REBASE_USE_BUILTIN test flag. This was left in place after my d03ebd411c6 (rebase: remove the rebase.useBuiltin setting, 2019-03-18) to help anyone who'd used the experimental flag and wanted to know that it was the default, or that they should transition their test environment to use the builtin rebase unconditionally. It's been more than long enough for those users to get a headsup about this. So remove all the scaffolding that was left inplace after d03ebd411c6. I'm also removing the documentation entry, if anyone still has this left in their configuration they can do some source archaeology to figure out what it used to do, which makes more sense than exposing every git user reading the documentation to this legacy configuration switch.

2021-03-23format-patch: allow a non-integral version numbersLibravatar ZheNing Hu1-9/+16
The `-v<n>` option of `format-patch` can give nothing but an integral iteration number to patches in a series.  Some people, however, prefer to mark a new iteration with only a small fixup with a non integral iteration number (e.g. an "oops, that was wrong" fix-up patch for v4 iteration may be labeled as "v4.1"). Allow `format-patch` to take such a non-integral iteration number. `<n>` can be any string, such as '3.1' or '4rev2'. In the case where it is a non-integral value, the "Range-diff" and "Interdiff" headers will not include the previous version.

The declarations of entry.c's public functions and structures currently reside in cache.h. Although not many, they contribute to the size of cache.h and, when changed, cause the unnecessary recompilation of modules that don't really use these functions. So let's move them to a new entry.h header. While at it let's also move a comment related to checkout_entry() from entry.c to entry.h as it's more useful to describe the function there.

Historically, Git has supported the 'Signed-off-by' commit trailer using the '--signoff' and the '-s' option from the command line. But users may need to provide other trailer information from the command line such as "Helped-by", "Reported-by", "Mentored-by", Now implement a new `--trailer <token>[(=|:)<value>]` option to pass other trailers to `interpret-trailers` and insert them into commit messages.

2021-03-21transport: also free remote_refs in transport_disconnect()Libravatar Andrzej Hunt2-6/+6
transport_get_remote_refs() can populate the transport struct's remote_refs. transport_disconnect() is already responsible for most of transport's cleanup - therefore we also take care of freeing remote_refs there. There are 2 locations where transport_disconnect() is called before we're done using the returned remote_refs. This patch changes those callsites to only call transport_disconnect() after the returned refs are no longer being used - which is necessary to safely be able to free remote_refs during transport_disconnect(). This commit fixes the following leak which was found while running t0000, but is expected to also fix the same pattern of leak in all locations that use transport_get_remote_refs(): Direct leak of 165 byte(s) in 1 object(s) allocated from: #0 0x49a6b2 in calloc /home/abuild/rpmbuild/BUILD/llvm-11.0.0.src/build/../projects/compiler-rt/lib/asan/asan_malloc_linux.cpp:154:3 #1 0x9a72f2 in xcalloc /home/ahunt/oss-fuzz/git/wrapper.c:140:8 #2 0x8ce203 in alloc_ref_with_prefix /home/ahunt/oss-fuzz/git/remote.c:867:20 #3 0x8ce1a2 in alloc_ref /home/ahunt/oss-fuzz/git/remote.c:875:9 #4 0x72f63e in process_ref_v2 /home/ahunt/oss-fuzz/git/connect.c:426:8 #5 0x72f21a in get_remote_refs /home/ahunt/oss-fuzz/git/connect.c:525:8 #6 0x979ab7 in handshake /home/ahunt/oss-fuzz/git/transport.c:305:4 #7 0x97872d in get_refs_via_connect /home/ahunt/oss-fuzz/git/transport.c:339:9 #8 0x9774b5 in transport_get_remote_refs /home/ahunt/oss-fuzz/git/transport.c:1388:4 #9 0x51cf80 in cmd_clone /home/ahunt/oss-fuzz/git/builtin/clone.c:1271:9 #10 0x4cd60d in run_builtin /home/ahunt/oss-fuzz/git/git.c:453:11 #11 0x4cb2da in handle_builtin /home/ahunt/oss-fuzz/git/git.c:704:3 #12 0x4ccc37 in run_argv /home/ahunt/oss-fuzz/git/git.c:771:4 #13 0x4cac29 in cmd_main /home/ahunt/oss-fuzz/git/git.c:902:19 #14 0x69c45e in main /home/ahunt/oss-fuzz/git/common-main.c:52:11 #15 0x7f6a459d5349 in __libc_start_main (/lib64/libc.so.6+0x24349) Signed-off-by: Andrzej Hunt <ajrhunt@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-03-20tree.h API: simplify read_tree_recursive() signatureLibravatar Ævar Arnfjörð Bjarmason4-14/+14
Simplify the signature of read_tree_recursive() to omit the "base", "baselen" and "stage" arguments. No callers of it use these parameters for anything anymore. The last function to call read_tree_recursive() with a non-"" path was read_tree_recursive() itself, but that was changed in ffd31f661d5 (Reimplement read_tree_recursive() using tree_entry_interesting(), 2011-03-25). The last user of the "stage" parameter went away in the last commit, and even that use was mere boilerplate. So let's remove those and rename the read_tree_recursive() function to just read_tree(). We had another read_tree() function that I've refactored away in preceding commits, since all in-tree users read trees recursively with a callback we can change the name to signify that this is the norm.

This finishes up a partial refactoring started in 6a0b0b6de99 (tree.c: update read_tree_recursive callback to pass strbuf as base, 2014-11-30). Moving the rest into overlay_tree_on_index() makes this index juggling we're doing easier to read.
