2022-02-09clone, submodule: pass partial clone filters to submodulesLibravatar Josh Steadmon1-0/+5
When cloning a repo with a --filter and with --recurse-submodules enabled, the partial clone filter only applies to the top-level repo. This can lead to unexpected bandwidth and disk usage for projects which include large submodules. For example, a user might wish to make a partial clone of Gerrit and would run: `git clone --recurse-submodules --filter=blob:5k https://gerrit.googlesource.com/gerrit`. However, only the superproject would be a partial clone; all the submodules would have all blobs downloaded regardless of their size. With this change, the same filter can also be applied to submodules, meaning the expected bandwidth and disk savings apply consistently. To avoid changing default behavior, add a new clone flag, `--also-filter-submodules`. When this is set along with `--filter` and `--recurse-submodules`, the filter spec is passed along to git-submodule and git-submodule--helper, such that submodule clones also have the filter applied. This applies the same filter to the superproject and all submodules. Users who need to customize the filter per-submodule would need to clone with `--no-recurse-submodules` and then manually initialize each submodule with the proper filter. Applying filters to submodules should be safe thanks to Jonathan Tan's recent work [1, 2, 3] eliminating the use of alternates as a method of accessing submodule objects, so any submodule object access now triggers a lazy fetch from the submodule's promisor remote if the accessed object is missing. This patch is a reworked version of [4], which was created prior to Jonathan Tan's work.

2022-02-08Documentation: add extensions.worktreeConfig detailsLibravatar Derrick Stolee1-0/+31
The extensions.worktreeConfig extension was added in 58b284a (worktree: add per-worktree config files, 2018-10-21) and was somewhat documented in Documentation/git-config.txt. However, the extensions.worktreeConfig value was not specified further in the list of possible config keys. The location of the config.worktree file is not specified, and there are some precautions that should be mentioned clearly, but are only mentioned in git-worktree.txt. Expand the documentation to help users discover the complexities of extensions.worktreeConfig by adding details and cross links in these locations (relative to Documentation/): - config/extensions.txt - git-config.txt - git-worktree.txt The updates focus on items such as * $GIT_DIR/config.worktree takes precedence over $GIT_COMMON_DIR/config. * The core.worktree and core.bare=true settings are incorrect to have in the common config file when extensions.worktreeConfig is enabled. * The sparse-checkout settings core.sparseCheckout[Cone] are recommended to be set in the worktree config. As documented in 11664196ac ("Revert "check_repository_format_gently(): refuse extensions for old repositories"", 2020-07-15), this extension must be considered regardless of the repository format version for historical reasons. A future change will update references to extensions.worktreeConfig within git-sparse-checkout.txt, but a behavior change is needed before making those updates.

2022-02-04branch: add --recurse-submodules option for branch creationLibravatar Glen Choo2-11/+29
To improve the submodules UX, we would like to teach Git to handle branches in submodules. Start this process by teaching "git branch" the --recurse-submodules option so that "git branch --recurse-submodules topic" will create the `topic` branch in the superproject and its submodules. Although this commit does not introduce breaking changes, it does not work well with existing --recurse-submodules commands because "git branch --recurse-submodules" writes to the submodule ref store, but most commands only consider the superproject gitlink and ignore the submodule ref store. For example, "git checkout --recurse-submodules" will check out the commits in the superproject gitlinks (and put the submodules in detached HEAD) instead of checking out the submodule branches. Because of this, this commit introduces a new configuration value, `submodule.propagateBranches`. The plan is for Git commands to prioritize submodule ref store information over superproject gitlinks if this value is true. Because "git branch --recurse-submodules" writes to submodule ref stores, for the sake of clarity, it will not function unless this configuration value is set. This commit also includes changes that support working with submodules from a superproject commit because "branch --recurse-submodules" (and future commands) need to read .gitmodules and gitlinks from the superproject commit, but submodules are typically read from the filesystem's .gitmodules and the index's gitlinks. These changes are: * add a submodules_of_tree() helper that gives the relevant information of an in-tree submodule (e.g. path and oid) and initializes the repository * add is_tree_submodule_active() by adding a treeish_name parameter to is_submodule_active() * add the "submoduleNotUpdated" advice to advise users to update the submodules in their trees Incidentally, fix an incorrect usage string that combined the 'list' usage of git branch (-l) with the 'create' usage; this string has been incorrect since its inception, a8dfd5eac4 (Make builtin-branch.c use parse_options., 2007-10-07).

2021-12-20branch: add flags and config to inherit trackingLibravatar Josh Steadmon1-1/+2
It can be helpful when creating a new branch to use the existing tracking configuration from the branch point. However, there is currently not a method to automatically do so. Teach git-{branch,checkout,switch} an "inherit" argument to the "--track" option. When this is set, creating a new branch will cause the tracking configuration to default to the configuration of the branch point, if set. For example, if branch "main" tracks "origin/main", and we run `git checkout --track=inherit -b feature main`, then branch "feature" will track "origin/main". Thus, `git status` will show us how far ahead/behind we are from origin, and `git pull` will pull from origin. This is particularly useful when creating branches across many submodules, such as with `git submodule foreach ...` (or if running with a patch such as [1], which we use at $job), as it avoids having to manually set tracking info for each submodule. Since we've added an argument to "--track", also add "--track=direct" as another way to explicitly get the original "--track" behavior ("--track" without an argument still works as well). Finally, teach branch.autoSetupMerge a new "inherit" option. When this is set, "--track=inherit" becomes the default behavior.

2021-12-15doc/config: mark ssh allowedSigners example as literalLibravatar Jeff King1-1/+1
The discussion for gpg.ssh.allowedSignersFile shows an example string that contains "user1@example.com,user2@example.com". Asciidoc thinks these are real email addresses and generates "mailto" footnotes for them. This makes the rendered content more confusing, as it has extra "[1]" markers: The file consists of one or more lines of principals followed by an ssh public key. e.g.: user1@example.com[1],user2@example.com[2] ssh-rsa AAAAX1... See ssh-keygen(1) "ALLOWED SIGNERS" for details. and also generates pointless notes at the end of the page: NOTES 1. user1@example.com mailto:user1@example.com 2. user2@example.com mailto:user2@example.com We can fix this by putting the example into a backtick literal block. That inhibits the mailto generation, and as a bonus typesets the example text in a way that sets it off from the regular prose (a tt font for html, or bold in the roff manpage).

2021-12-09ssh signing: make verify-commit consider key lifetimeLibravatar Fabian Stelzer1-0/+5
If valid-before/after dates are configured for this signatures key in the allowedSigners file then the verification should check if the key was valid at the time the commit was made. This allows for graceful key rollover and revoking keys without invalidating all previous commits. This feature needs openssh > 8.8. Older ssh-keygen versions will simply ignore this flag and use the current time. Strictly speaking this feature is available in 8.7, but since 8.7 has a bug that makes it unusable in another needed call we require 8.8. Timestamp information is present on most invocations of check_signature. However signer ident is not. We will need the signer email / name to be able to implement "Trust on first use" functionality later. Since the payload contains all necessary information we can parse it from there. The caller only needs to provide us some info about the payload by setting payload_type in the signature_check struct. - Add payload_type field & enum and payload_timestamp to struct signature_check - Populate the timestamp when not already set if we know about the payload type - Pass -Overify-time={payload_timestamp} in the users timezone to all ssh-keygen verification calls - Set the payload type when verifying commits - Add tests for expired, not yet valid and keys having a commit date outside of key validity as well as within Signed-off-by: Fabian Stelzer <fs@gigacodes.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-12-05grep: clarify what `grep.patternType=default` meansLibravatar Junio C Hamano1-1/+2
We documented that with grep.patternType set to default, the "git grep" command returns to "the default matching behavior" in 84befcd0 (grep: add a grep.patternType configuration setting, 2012-08-03). The grep.extendedRegexp configuration variable was the only way to configure the behavior before that, after b22520a3 (grep: allow -E and -n to be turned on by default via configuration, 2011-03-30) introduced it. It is understandable that we referred to the behavior that honors the older configuration variable as "the default matching" behavior. It is fairly clear in its log message: When grep.patternType is set to a value other than "default", the grep.extendedRegexp setting is ignored. The value of "default" restores the current default behavior, including the grep.extendedRegexp behavior. But when the paragraph is read in isolation by a new person who is not aware of that backstory (which is the synonym for "most users"), the "default matching behavior" can be read as "how 'git grep' behaves without any configuration variables or options", which is "match the pattern as BRE". Clarify what the passage means by elaborating what the phrase "default matching behavior" wanted to mean.

2021-11-19ssh signing: support non ssh-* keytypesLibravatar Fabian Stelzer1-7/+10
The user.signingKey config for ssh signing supports either a path to a file containing the key or for the sake of convenience a literal string with the ssh public key. To differentiate between those two cases we check if the first few characters contain "ssh-" which is unlikely to be the start of a path. ssh supports other key types which are not prefixed with "ssh-" and will currently be treated as a file path and therefore fail to load. To remedy this we move the prefix check into its own function and introduce the prefix `key::` for literal ssh keys. This way we don't need to add new key types when they become available. The existing `ssh-` prefix is retained for compatibility with current user configs but removed from the official documentation to discourage its use.

The "git log" command limits its output to the commits that contain strings matched by a pattern when the "--grep=<pattern>" option is used, but unlike output from "git grep -e <pattern>", the matches are not highlighted, making them harder to spot. Teach the pretty-printer code to highlight matches from the "--grep=<pattern>", "--author=<pattern>" and "--committer=<pattern>" options (to view the last one, you may have to ask for --pretty=fuller). Also, it must be noted that we are effectively greping the content twice (because it would be a hassle to rework the existing matching code to do a /g match and then pass it all down to the coloring code), however it only slows down "git log --author=^H" on this repository by around 1-2% (compared to v2.33.0), so it should be a small enough slow down to justify the addition of the feature.

2021-09-14midx.c: respect 'pack.writeBitmapHashcache' when writing bitmapsLibravatar Taylor Blau1-0/+4
In the previous commit, the bitmap writing code learned to propagate values from an existing hash-cache extension into the bitmap that it is writing. Now that that functionality exists, let's expose it by teaching the 'git multi-pack-index' builtin to respect the `pack.writeBitmapHashCache` option so that the hash-cache may be written at all. Two minor points worth noting here: - The 'git multi-pack-index write' sub-command didn't previously read any configuration (instead this is handled in the base command). A separate handler is added here to respect this write-specific config option. - I briefly considered adding a 'bitmap_flags' field to the static options struct, but decided against it since it would require plumbing through a new parameter to the write_midx_file() function. Instead, a new MIDX-specific flag is added, which is translated to the corresponding bitmap one. Signed-off-by: Taylor Blau <me@ttaylorr.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-09-10ssh signing: verify signatures using ssh-keygenLibravatar Fabian Stelzer1-0/+35
To verify a ssh signature we first call ssh-keygen -Y find-principal to look up the signing principal by their public key from the allowedSignersFile. If the key is found then we do a verify. Otherwise we only validate the signature but can not verify the signers identity. Verification uses the gpg.ssh.allowedSignersFile (see ssh-keygen(1) "ALLOWED SIGNERS") which contains valid public keys and a principal (usually user@domain). Depending on the environment this file can be managed by the individual developer or for example generated by the central repository server from known ssh keys with push access. This file is usually stored outside the repository, but if the repository only allows signed commits/pushes, the user might choose to store it in the repository. To revoke a key put the public key without the principal prefix into gpg.ssh.revocationKeyring or generate a KRL (see ssh-keygen(1) "KEY REVOCATION LISTS"). The same considerations about who to trust for verification as with the allowedSignersFile apply. Using SSH CA Keys with these files is also possible. Add "cert-authority" as key option between the principal and the key to mark it as a CA and all keys signed by it as valid for this CA. See "CERTIFICATES" in ssh-keygen(1).

2021-09-10ssh signing: add ssh key format and signing codeLibravatar Fabian Stelzer2-2/+7
Implements the actual sign_buffer_ssh operation and move some shared cleanup code into a strbuf function Set gpg.format = ssh and user.signingkey to either a ssh public key string (like from an authorized_keys file), or a ssh key file. If the key file or the config value itself contains only a public key then the private key needs to be available via ssh-agent. gpg.ssh.program can be set to an alternative location of ssh-keygen. A somewhat recent openssh version (8.2p1+) of ssh-keygen is needed for this feature. Since only ssh-keygen is needed it can this way be installed seperately without upgrading your system openssh packages.

2021-09-07pull: remove support for `--rebase=preserve`Libravatar Johannes Schindelin2-8/+0
In preparation for `git-rebase--preserve-merges.sh` entering its after life, we remove this (deprecated) option that would still rely on it. To help users transition who still did not receive the memo about the deprecation, we offer a helpful error message instead of throwing our hands in the air and saying that we don't know that option, never heard of it.

2021-09-01docs: clarify the interaction of transfer.hideRefs and namespacesLibravatar Kim Altintop1-5/+9
Expand the section about namespaces in the documentation of `transfer.hideRefs` to point out the subtle differences between `upload-pack` and `receive-pack`. ffcfb68176 (upload-pack.c: treat want-ref relative to namespace, 2021-07-30) taught `upload-pack` to reject `want-ref`s for hidden refs, which is now mentioned. It is clarified that at no point the name of a hidden ref is revealed, but the object id it points to may.

2021-08-30sequencer: advise if skipping cherry-picked commitLibravatar Josh Steadmon1-0/+3
Silently skipping commits when rebasing with --no-reapply-cherry-picks (currently the default behavior) can cause user confusion. Issue warnings when this happens, as well as advice on how to preserve the skipped commits. These warnings and advice are displayed only when using the (default) "merge" rebase backend.

2021-08-27docs: use "character encoding" to refer to commit-object encodingLibravatar Jeff King1-1/+1
The word "encoding" can mean a lot of things (e.g., base64 or quoted-printable encoding in emails, HTML entities, URL encoding, and so on). The documentation for i18n.commitEncoding and i18n.logOutputEncoding uses the phrase "character encoding" to make this more clear. Let's use that phrase in other places to make it clear what kind of encoding we are talking about. This patch covers the gui.encoding option, as well as the --encoding option for git-log, etc (in this latter case, I word-smithed the sentence a little at the same time). That, coupled with the mention of iconv in the --encoding description, should make this more clear. The other spot I looked at is the working-tree-encoding section of gitattributes(5). But it gives specific examples of encodings that I think make the meaning pretty clear already. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
