We need to ensure that we are actually modifying `git` configs/.gitmodules when we actually change submod.toml or CLI options. Our config exists to simplify the user experience, but we need to ensure that the underlying git configuration is also updated accordingly. + +2. I'd like to **eliminate** all use of `git` cli calls. + + - `Gitoxide` has good coverage of _most_ of what we need, and can fully handle: + + - Reading and writing git configs (`gix_config`) + - **Reading** `.gitmodules` files (`gix_submodule`) + - Reporting repository and submodule status + - Most fetching (it can't, however `init` a submodule yet) + + - `git2` has all of the remaining functionality we need: + + - It can completely create and initialize submodules, including cloning them. + - Any config ops not covered by gix_config can be handled by `git2`. + + - Absolute worst case, we can use `gix_command` to run `git` commands, which at least gives us a consistent interface and pushes validation and error handling down to the `gitoxide` layer. + - **Bottom line: If you see a `git` command in the code; it's wrong.** + +3. Besides triggering creation and updates, we should generally avoid trying to emulate `git` tasks. We update and tell git to do the work through `gitoxide` and `git2`, and keep its configs in sync with our own. + + - We don't need to handle fetching behavior, for example. We just need to make sure that git is configured to fetch how the user wants it to, and then let git handle the fetching. We can trigger it with `git2` or `gix` but we don't do it ourselves. + +4. Minimize direct file ops. Again, let `gitoxide` and `git2` handle the file ops. We should not be reading or writing `.gitmodules` or `.git/config` directly, except through the git libraries. The exception _might_ be `sparse-checkout` files, but even those I think worst case we can use `gix_command` to handle them since git clearly can do it. + + - **Possible Exception**: Our `nuke-it-from-orbit` and `delete` commands -- using internal `git submodule deinit` like functionality _should_ be fine, but if it doesn't work we have to be able to do direct deletion of the submodule directory and files. `git2` should have this functionality of basically the library equivalent of `git submodule deinit`, and worst case we can use `gix_command` to run the command and then delete the submodule directory and files ourselves. We also need to look at exactly what git does in a deinit -- we may need to add `git rm --cached` like behavior (possibly with an optional flag like `--it-never-existed`). We should also remove the submodule from the `.gitmodules` file and the `.git/config` file, but we can do that through `git2` or `gix_config`. + +5. The longterm goal is to solely use `gix` when it has the full functionality we need, so we need to architect for easy transition between `gix` and `git2` as needed. Basically we need our types to be interchangeable between `gix` and `git2` where possible, so that we can swap them out as needed without having to rewrite large portions of the code. + +6. A possible issue we should think about. We don't currently have a way to differentiate configuration at the user, repository, submodule, superproject, and global levels. We should consider how we can handle that in the future, but for now we can just assume that all configuration is at the repository level. For example, if we allowed user configs (i.e. `~/.config/submod.toml` or in a repo `.dev.submod.toml` (added to the `.gitignore`)), we would write the user `.git/config` instead of the `.gitmodules`. That would let users add/change submodule behavior for a repository to suit their needs without impacting the repo behavior. This is a future consideration, but something we should keep in mind as we design our configuration system. I think _it mostly_ matters for user and repo level. Most folks don't want global submodule configs, and we can leave it on the user to differentiate between sub-repo and superproject configs. + + - A related abstraction I think would be useful is to differentiate `developer` and `user` configs. Kind of like `developer` dependencies -- i.e. anyone working on the project itself can pull the developer config and get those submodules, but a user who clones the project to build it doesn't need to pull those submodules. You could use this to basically vendor documentation for dependencies, for example (very helpful for MCP context). This is a future consideration, but I think it would be useful to keep in mind as we design our configuration system. That is, they _would_ have the submodules in the _.gitignore_ for the project, but the `submod.toml` could be used to pull them. As I write this, I realize all we would need to do is add a `developer` flag and write the submodule path to the `.gitignore` file. The developer flag would tell us to write submodule settings to `.git/config` instead of `.gitmodules`. (I'm going to go ahead and pencil this in in the commands.rs file, but we can revisit it later.) + - A really killer version of this would be to automatically find the project docs and make them sparse. We could look at how tools like `context7` handle very similar behavior (I'm guessing look for a docs dir or _.md/_.mdx/*.rst files.) Like those, you'd want it to be able to handle pulling from public git*and where that doesn't work well\*, snapshotting webpages to markdown. Throwing a little bit of search on top of that would be even better... (maybe that's out of scope or more suitable for a dedicated tool, but it's a neat idea.) + +**Update**: After some research, I went ahead and implemented the foundations for `figment` for our config/toml handling. It enormously simplified things, pushing all of the config loading, merging, and validation to `figment`, which is a great fit for our needs. It also gives us good provenance for our config, so we can easily see where settings came from (i.e. CLI options, submod.toml, etc.). That will allow us to just write the logic for how we push that information to git's configuration, and let `figment` handle the rest. This also means we can easily add new config sources in the future (like user configs) without having to rewrite a lot of code. (I actually penciled in user and developer configs in a comment in the config.rs file; but we can revisit that later.) + +Summary of the flow: + +**gix** -> **git2** -> **gix_command** (if needed) + +## Missing Core Functionality to Support All Features + +### Setting and Updating Global Defaults + +Git, of course, does not have a concept of "global defaults" for submodules (as far as I'm aware). That's an abstraction _we introduced_ to simplify the user experience. However, we need to ensure that these defaults are reflected in the git configuration. It means that where a user has not explicitly set a value in their `submod.toml` for a specific submodule, we should use the global defaults to fill in the gaps when we update `.gitmodules` (through git2). + +- We _should already_ have a method that sets global defaults because the behavior should be there for handling global defaults in the config + - **I couldn't find it in the codebase**, so we need to verify it exists and is working as expected. This is something we also need to make sure is tested. + +**The behavior ^^should^^ be**: + +- Any default setting for `ignore`, `fetch`, `update` _are not_ written to the `.gitmodules` file _or the submod.toml_. We leave those blank. + - If a user sets a specific value for `ignore`, `fetch`, or `update` in their `submod.toml` or through CLI options, we write that value to the `submod.toml` file but not the `.gitmodules` file (because there are no global default overrides in git -- we reconcile it). + - We treat those as overrides of the global defaults (i.e. if the user sets `ignore = "all"` as a global default, but then sets `ignore = "none"` for a specific submodule, we change all other submodules to `ignore = "all"` in `.gitmodules` but leave the specific submodule as `ignore = "none"` in the `.gitmodules` file), using our config as the source of truth. +- **Non-default values for ignore, fetch, update**. For non-default values, we always write them to both `submod.toml` and `.gitmodules`. We just need to deconflict them with the global defaults (submodule config wins) before updating `.gitmodules`. +- (sidenote: consider adding `shallow` as a global default, but I think we can leave that for later) + +### Setting and Updating All Other Settings + +Like with the global defaults, we need to ensure that our configuration is getting accurately reflected in the `.gitmodules` file and the `.git/config` file. This means that when we update settings in `submod.toml` or through CLI options, we need to ensure that those changes are also reflected in the git configuration. + +**The behavior ^^should^^ be**: + +- **All other settings get written to both submod.toml and .gitmodules if explicitly set** `submod.toml` and `.gitmodules` files. There are no global defaults for these settings, so we always write them to both files _if explicitly set_ in the `submod.toml` or CLI options. + - Note that some of our "defaults" are actually more like _inferred settings_, those should always get written to both. The biggest example is `name`, which is actually required for both our ops and git's submodule handling, but we infer it from the submodule path (it's hidden on the `add` command). + +### Toml/Config Handling + +A lot of what we need to reconcile and work on is keeping our config properly updated and aligned with the git configuration. New commands and features require granular control over how we read and write the configuration, so we need to ensure that our config handling is robust and flexible. + +After some investigation, I found that `figment` is a good choice for our toml handling. We can replace a lot of our manual parsing and validation with `figment`'s built-in functionality, which will simplify our code and make it more maintainable. We already have serialize/deserialize traits for our types, so it's literally just a few lines of code. Figment handles layer config loading, merging, and validation for us and keeps good provenance, so we can focus on the actual logic of our commands. + +### CLI Parsing and Validation + +- **Leveraging Clap**. I added `clap`'s `ValueEnum` trait to all of our config enums. This integrates validation and parsing directly with clap. We need to update all the handling logic from the parsed arguments to reflect this, and I suspect remove a lot of code. +- I also specified clap value parsers for _everything_ that needs to be parsed, so we can remove a lot of the manual parsing and validation code. +- **Type changes**. I also narrowed some of the existing default types to more specific types. Specifically, `path` now uses `OsString` instead of `String` (because it can handle non-UTF8 paths). I didn't make this PathBuf because we're not actually using it as a path, but I added a conversion function in `utilities.rs` to convert it to a `PathBuf` when needed. + +#### Add config generation + +We need to add config generation for submod.toml. This should be pretty trivial since we already have the logic to add/update it. + +- I did a lot of work beefing up the example config in [`sample_config/submod.toml`](sample_config/submod.toml). I also added placeholders in `commands.rs` for a config generation command with options. + - The command has two options in terms of content: + - `--from-setup` to generate a config from the current git submodule setup (i.e. the current `.gitmodules` and `.git/config` files). This is just reversing the process we do in `add` and `update` commands. + - `--template` to generate a config from a template. This would basically just copy the `sample_config/submod.toml` file to the current directory, and then the user can edit it as needed (how do we make sure it gets packaged in the binary? Or I guess we could fetch it from the repo... but that assumes internet connectivity - new territory for me with rust). + +## Implement the New Commands and Make Sure Existing Commands Do What They Should + +We need to implement the new commands and ensure that existing commands do what they should. This includes: + +1. `submod add` (see above on making sure it does what it should) + + - Once question is how to handle a user trying to add an existing submodule. I'd lean towards erroring out and telling them to use `submod change` instead. We should spit out their exact command as a `submod change` command in our error message so they can easily copy/paste it. + - We need to ensure that it updates the `.gitmodules` file and the `.git/config` file as needed. + - Add `shallow` and `no-init` options to the command. + - We also need to make sure submod add _is_ _initiating_ the submodule; I can't tell if it does that now, but it should. For us we just use the `submod init` logic to do that, so we need to ensure that it works as expected. + +2. `submod change` (new) to update or change all options for a specific submodule. + + - We just need the deconfliction logic on how to handle updates/changes. + - Here if a user tries to change a submodule that _doesn't exist_ I'd lean towards a prompt asking if they want to create it, which would redirect it to `submod add`. + +3. `submod change-global` (new) to update or change global defaults for all submodules in the repo. + + - As discussed above, we should already have this logic, and if we don't, it is something we have to do anyway. + +4. `check` We need to make sure this is differentiated from `submod list`. + + - `submod check` should check and report the current status of all submodules. + - I had considered adding a `submod status` command, but I think that functionality can go here. + - `gix` already has a fair amount of statistics and status summary features for its own cli; we should be able to directly add those without writing our own. The gix crate implementing all of its CLI capabilities is `gitoxide-core` (library part), actual CLI handling is in the main `gitoxide` crate. + +5. `submod list` (new) We need to make sure this is properly listing all submodules with their current settings. + +6. `submod init` We need to make sure this is properly initializing submodules. + + - Remove any existing reliance on `git` commands for this. + +7. `submod delete` (new) to remove a submodule from the repository and the submod.toml file, and all of its files. + + - This should be a hard delete, removing the submodule directory and files, and deleting all references to it in git's configuration. + - We need to ensure that it updates the `.gitmodules` file and the `.git/config` file as needed and actually clears the submodule's entry from the configuration. + - We will also use this logic for the `nuke-it-from-orbit --kill` command, so we need to ensure that it works as expected. + +8. `submod disable` (new) to set a submodule to inactive nondestructively, allowing it to be re-enabled later. + + - Very simple -- set the submodule's `active` flag to `false` in the `submod.toml` and `.gitmodules` files. + +9. `submod update` -- just need to move any `git` calls to `git2` or `gix_command` as needed. + +10. `submod reset` -- just need to move any `git` calls to `git2` or `gix_command` as needed. + +11. `submod sync` -- this should be fine, as it's just a wrapper for `check, init, update` commands. If we make `check` more of a status command, we would need to separate the `check` logic for this command (check would do both). + +12. `submod generate-config` (new) to generate a submod.toml file from the current git submodule setup or a template. + + - This should be pretty trivial since we already have the logic to add/update it. + - We can use the `--from-setup` and `--template` options as discussed above. + - the optional `--output` option is a PathBuf to write the generated config to, defaulting to `submod.toml` in the current directory. + +13. `submod nuke-it-from-orbit` (new). + + - Most of the underlying logic is used or will be used in other parts of the codebase. + - By default it + - By default this is an **extra hard reset**, removing all submodules and files, deleting all references to them in git's configuration, resyncing with git, before _adding them all back to the gitconfig from your submod.toml settings_. You can optionally pass the `--kill` flag to _completely_ remove them without adding them back to the gitconfig, and deleting them from your submod.toml (this is the same as `submod delete` but for multiple submodules). + +14. `submod completions` (new) This is super simple. It's just a parse operation with a `generate` command passing the shell type as an argument. I already added `Shell` and `generate` to the imports and types for the command, and added the dependencies to `Cargo.toml`. We just need that quick function to trigger them. + +Other: - **global `--config` option**. I made this truly global so it can be used with any command. It is also now a PathBuf instead of a String, so it can be used with clap's value parsers. It defaults to `submod.toml` in the current directory, but can be overridden with the `--config` option. + +- **We need to make sure we are actually using this option in all commands**. Be on the lookout for any commands that assume a config location or don't use the global config option. We should be using the `config` variable in `commands.rs` to get the config location and read/write it as needed. + +## Tests + +Once we get all of this implemented, we need to comb through the tests to ensure that they are still valid and cover all of the new functionality. We should also add integration tests for any new commands and features we implement. + +On the plus side, we can actually use the `nuke-it-from-orbit` command for test tear down. + +## Documentation + +We're in a good place but we'll need to go through the README to make it reflect the new commands and features. + +## API Notes + +While we need more research on the APIs for `gix` and `git2`, I've found quite a few useful resources: + +- Data checks: + - The `gix` [`repository`](https://docs.rs/gix/latest/gix/struct.Repository.html) struct has a lot of useful functionality for introspecting the repository and submodules, including: + - `modules()` returns a shared _live_ view of the `.gitmodules` file, so you can use it to read the current submodule configuration and validate changes. + - `submodules()` returns an iterator over the submodules in the repository, each submodule object is essentially a Repository object with its own methods for introspection and manipulation. + - `workdir()` returns the worktree path containing all checkout items (if it exists) + - `workdir_path()` is a convenience method that normalizes relative paths with the worktree path, so you can use it to get the full path anything in the worktree. (takes asRef `Bstr` and returns `Path`) + - `kind()` returns the kind of repository (bare, worktree, etc.), which can be useful for determining how to handle submodules. (gix::repository::Kind with variants Bare, Worktree and Submodule). The enum itself has method `is_bare()` to check for a bare repo. + - `head_id()` returns the current HEAD ID of the submodule or repository. + - `head_tree()` returns the current HEAD [Tree](https://docs.rs/gix/latest/gix/struct.Tree.html) of the submodule or repository, which can be useful for checking the current state of the submodule. + - `head_name()` returns the name of the symbolic ref for HEAD; note that it may not exist yet -- it can have a name and no reference. + - `pathspec()` not really for now, but if we ever wanted to get real fancy with using pathspecs for live filtering of submodules (i.e. we could show exactly what a sparse checkout would look like), this is the method for it. + - `try_find_remote()` returns a `Result>` for the remote with the given name, which can be useful for checking if a submodule or repo has a remote set up. Similarly: + - `find_fetch_remote()` mirrors `git fetch` in how to finds and retrieves a remote. + - `find_default_remote()` to find the default remote for the repo + - `open_modules_file()` returns a `Result` for the `.gitmodules` file, which can be used to read the current submodule configuration. Unlike `.modules` this view is stale. + - `current_dir()` returns the current working directory of the repository, which can be useful for relative paths. + - `path()` returns the path to the repository .git directory itself; we can use to construct sparse-checkout index paths + - `main_repo()` returns the superproject repo object diff --git a/.gitattributes b/.gitattributes index bd8269f..8c9b591 100644 --- a/.gitattributes +++ b/.gitattributes @@ -1,3 +1,7 @@ +# SPDX-FileCopyrightText: 2025 Adam Poulemanos <89049923+bashandbone@users.noreply.github.com> +# +# SPDX-License-Identifier: LicenseRef-PlainMIT OR MIT + # Set default behavior to automatically normalize line endings * text=auto @@ -13,6 +17,7 @@ *.js text eol=lf *.json text eol=lf *.jsx text eol=lf +*.license text eol=lf *.md text eol=lf *.mdx text eol=lf *.mts text eol=lf @@ -20,6 +25,7 @@ *.py text eol=lf *.rs text eol=lf *.sh text eol=lf +*.spdx text eol=lf *.svelte text eol=lf *.svg text eol=lf *.toml text eol=lf diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index f610e5d..6352b0c 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -1,3 +1,7 @@ +# SPDX-FileCopyrightText: 2025 Adam Poulemanos <89049923+bashandbone@users.noreply.github.com> +# +# SPDX-License-Identifier: LicenseRef-PlainMIT OR MIT + name: CI on: diff --git a/.github/workflows/docs.yml b/.github/workflows/docs.yml index e24da1b..2484cf5 100644 --- a/.github/workflows/docs.yml +++ b/.github/workflows/docs.yml @@ -1,3 +1,7 @@ +# SPDX-FileCopyrightText: 2025 Adam Poulemanos <89049923+bashandbone@users.noreply.github.com> +# +# SPDX-License-Identifier: LicenseRef-PlainMIT OR MIT + name: Documentation on: diff --git a/.github/workflows/release.yml b/.github/workflows/release.yml index 87cc4d7..750210b 100644 --- a/.github/workflows/release.yml +++ b/.github/workflows/release.yml @@ -1,3 +1,7 @@ +# SPDX-FileCopyrightText: 2025 Adam Poulemanos <89049923+bashandbone@users.noreply.github.com> +# +# SPDX-License-Identifier: LicenseRef-PlainMIT OR MIT + name: Release permissions: diff --git a/.gitignore b/.gitignore index ea8c4bf..be1c189 100644 --- a/.gitignore +++ b/.gitignore @@ -1 +1,5 @@ +# SPDX-FileCopyrightText: 2025 Adam Poulemanos <89049923+bashandbone@users.noreply.github.com> +# +# SPDX-License-Identifier: LicenseRef-PlainMIT OR MIT + /target diff --git a/.prettierignore b/.prettierignore index 6f5f3d1..9260de7 100644 --- a/.prettierignore +++ b/.prettierignore @@ -1 +1,5 @@ +# SPDX-FileCopyrightText: 2025 Adam Poulemanos <89049923+bashandbone@users.noreply.github.com> +# +# SPDX-License-Identifier: LicenseRef-PlainMIT OR MIT + *.rs diff --git a/.prettierrc.toml b/.prettierrc.toml index 74b5898..cb1b9b9 100644 --- a/.prettierrc.toml +++ b/.prettierrc.toml @@ -1,3 +1,7 @@ +# SPDX-FileCopyrightText: 2025 Adam Poulemanos <89049923+bashandbone@users.noreply.github.com> +# +# SPDX-License-Identifier: LicenseRef-PlainMIT OR MIT + tabWidth = 4 useTabs = false diff --git a/.roo/mcp.json.license b/.roo/mcp.json.license new file mode 100644 index 0000000..e590b97 --- /dev/null +++ b/.roo/mcp.json.license @@ -0,0 +1,3 @@ +SPDX-FileCopyrightText: 2025 Adam Poulemanos <89049923+bashandbone@users.noreply.github.com> + +SPDX-License-Identifier: LicenseRef-PlainMIT OR MIT diff --git a/.roomodes b/.roomodes index 8542736..58fc34d 100644 --- a/.roomodes +++ b/.roomodes @@ -1,16 +1,16 @@ { "customModes": [ { - "slug": "plain-docs-writer", - "name": "📝 Plain Documentation Writer", - "roleDefinition": "You are a technical documentation expert.

Crate gix_config

Source
Expand description

§gix_config

+

This crate is a high performance git-config file reader and writer. It +exposes a high level API to parse, read, and write git-config files.

+

This crate has a few primary offerings and various accessory functions. The +table below gives a brief explanation of all offerings, loosely in order +from the highest to lowest abstraction.

+
+ + + +
OfferingDescriptionZero-copy?
FileAccelerated wrapper for reading and writing values.On some reads1
parse::StateSyntactic events for git-config files.Yes
value wrappersWrappers for git-config value types.Yes
+
+

This crate also exposes efficient value normalization which unescapes +characters and removes quotes through the normalize_* family of functions, +located in the value module.

+

§Known differences to the git config specification

+
    +
  • Legacy headers like [section.subsection] are supposed to be turned into to lower case and compared +case-sensitively. We keep its case and compare case-insensitively.
    • +
+

§Feature Flags

+
    +
  • serde — Data structures implement serde::Serialize and serde::Deserialize.
    • +
+

  1. When read values do not need normalization and it wasn’t parsed in ‘owned’ mode. ↩

Modules§

color
file
A high level wrapper around a single or multiple git-config file, for reading and mutation.

This module handles parsing a git-config file. Generally speaking, you +want to use a higher abstraction such as File unless you have some +explicit reason to work with events instead.
path
source
value

Structs§

Boolean
Any value that can be interpreted as a boolean.
Color
Any value that may contain a foreground color, background color, a +collection of color (text) modifiers, or a combination of any of the +aforementioned values, like red or brightgreen.
File
High level git-config reader and writer.
Integer
Any value that can be interpreted as an integer.
KeyRef
An unvalidated parse result of parsing input like remote.origin.url or core.bare.
Path
Any value that can be interpreted as a path to a resource on disk.

Enums§

Struct Repository

Source 
pub struct Repository {
+    pub refs: RefStore,
+    pub objects: OdbHandle,
+    /* private fields */
+}
Expand description

A thread-local handle to interact with a repository from a single thread.

+

It is Send but not Sync - for the latter you can convert it to_sync(). +Note that it clones itself so that it is empty, requiring the user to configure each clone separately, specifically +and explicitly. This is to have the fastest-possible default configuration available by default, but allow +those who experiment with workloads to get speed boosts of 2x or more.

+

§Send only with parallel feature

+

When built with default-features = false, this type is not Send. +The minimal feature set to activate Send is features = ["parallel"].

+

Fields§

§refs: RefStore

A ref store with shared ownership (or the equivalent of it).

+
§objects: OdbHandle

A way to access objects.

+

Implementations§

Source§

impl Repository

Source

pub fn attributes( + &self, + index: &State, + attributes_source: Source, + ignore_source: Source, + exclude_overrides: Option<Search>, +) -> Result<AttributeStack<'_>, Error>

Available on (crate features attributes or excludes) and crate feature attributes only.

Configure a file-system cache for accessing git attributes and excludes on a per-path basis.

+

Use attribute_source to specify where to read attributes from. Also note that exclude information will +always try to read .gitignore files from disk before trying to read it from the index.

+

Note that no worktree is required for this to work, even though access to in-tree .gitattributes and .gitignore files +would require a non-empty index that represents a git tree.

+

This takes into consideration all the usual repository configuration, namely:

+
    +
  • $XDG_CONFIG_HOME/…/ignore|attributes if core.excludesFile|attributesFile is not set, otherwise use the configured file.
    • +
  • $GIT_DIR/info/exclude|attributes if present.
    • +
+
Source

pub fn attributes_only( + &self, + index: &State, + attributes_source: Source, +) -> Result<AttributeStack<'_>, Error>

Available on (crate features attributes or excludes) and crate feature attributes only.

Like attributes(), but without access to exclude/ignore information.

+
Source

pub fn excludes( + &self, + index: &State, + overrides: Option<Search>, + source: Source, +) -> Result<AttributeStack<'_>, Error>

Available on (crate features attributes or excludes) and crate feature excludes only.

Configure a file-system cache checking if files below the repository are excluded, reading .gitignore files from +the specified source.

+

Note that no worktree is required for this to work, even though access to in-tree .gitignore files would require +a non-empty index that represents a tree with .gitignore files.

+

This takes into consideration all the usual repository configuration, namely:

+
    +
  • $XDG_CONFIG_HOME/…/ignore if core.excludesFile is not set, otherwise use the configured file.
    • +
  • $GIT_DIR/info/exclude if present.
    • +
+

When only excludes are desired, this is the most efficient way to obtain them. Otherwise use +Repository::attributes() for accessing both attributes and excludes.

+
Source§

impl Repository

Configure how caches are used to speed up various git repository operations

+
Source

pub fn object_cache_size(&mut self, bytes: impl Into<Option<usize>>)

Sets the amount of space used at most for caching most recently accessed fully decoded objects, to Some(bytes), +or None to deactivate it entirely.

+

Note that it is unset by default but can be enabled once there is time for performance optimization. +Well-chosen cache sizes can improve performance particularly if objects are accessed multiple times in a row. +The cache is configured to grow gradually.

+

Note that a cache on application level should be considered as well as the best object access is not doing one.

+
Source

pub fn object_cache_size_if_unset(&mut self, bytes: usize)

Set an object cache of size bytes if none is set.

+

Use this method to avoid overwriting any existing value while assuring better performance in case no value is set.

+
Source

pub fn compute_object_cache_size_for_tree_diffs(&self, index: &State) -> usize

Available on crate feature index only.

Return the amount of bytes the object cache should be set to to perform +diffs between trees who are similar to index in a typical source code repository.

+

Currently, this allocates about 10MB for every 10k files in index, and a minimum of 4KB.

+
Source§

impl Repository

Handling of InMemory object writing

+
Source

pub fn with_object_memory(self) -> Self

When writing objects, keep them in memory instead of writing them to disk. +This makes any change to the object database non-persisting, while keeping the view +to the object database consistent for this instance.

+
Source§

impl Repository

Source

pub fn checkout_options( + &self, + attributes_source: Source, +) -> Result<Options, Error>

Available on crate feature worktree-mutation only.

Return options that can be used to drive a low-level checkout operation. +Use attributes_source to determine where .gitattributes files should be read from, which depends on +the presence of a worktree to begin with. +Here, typically this value would be gix_worktree::stack::state::attributes::Source::IdMapping

+
Source§

impl Repository

Query configuration related to branches.

+
Source

pub fn branch_names(&self) -> BTreeSet<&str>

Return a set of unique short branch names for which custom configuration exists in the configuration, +if we deem them trustworthy.

+
§Note
+

Branch names that have illformed UTF-8 will silently be skipped.

+
Source

pub fn branch_remote_ref_name( + &self, + name: &FullNameRef, + direction: Direction, +) -> Option<Result<Cow<'_, FullNameRef>, Error>>

Returns the validated reference name of the upstream branch on the remote associated with the given name, +which will be used when merging. +The returned value corresponds to the branch.<short_branch_name>.merge configuration key for remote::Direction::Fetch. +For the push direction the Git configuration is used for a variety of different outcomes, +similar to what would happen when running git push <name>.

+

Returns None if there is nothing configured, or if no remote or remote ref is configured.

+
§Note
+

The returned name refers to what Git calls upstream branch (as opposed to upstream tracking branch). +The value is also fast to retrieve compared to its tracking branch.

+

See also Reference::remote_ref_name().

+
Source

pub fn branch_remote_tracking_ref_name( + &self, + name: &FullNameRef, + direction: Direction, +) -> Option<Result<Cow<'_, FullNameRef>, Error>>

Return the validated name of the reference that tracks the corresponding reference of name on the remote for +direction. Note that a branch with that name might not actually exist.

+
    +
  • with remote being remote::Direction::Fetch, we return the tracking branch that is on the destination +side of a src:dest refspec. For instance, with name being main and the default refspec +refs/heads/*:refs/remotes/origin/*, refs/heads/main would match and produce refs/remotes/origin/main.
    • +
  • with remote being remote::Direction::Push, we return the tracking branch that corresponds to the remote +branch that we would push to. For instance, with name being main and no setup at all, we +would push to refs/heads/main on the remote. And that one would be fetched matching the +refs/heads/*:refs/remotes/origin/* fetch refspec, hence refs/remotes/origin/main is returned. +Note that push refspecs can be used to map main to other (using a push refspec refs/heads/main:refs/heads/other), +which would then lead to refs/remotes/origin/other to be returned instead.
    • +
+

Note that if there is an ambiguity, that is if name maps to multiple tracking branches, the first matching mapping +is returned, according to the order in which the fetch or push refspecs occur in the configuration file.

+

See also Reference::remote_tracking_ref_name().

+
Source

pub fn upstream_branch_and_remote_for_tracking_branch( + &self, + tracking_branch: &FullNameRef, +) -> Result<Option<(FullName, Remote<'_>)>, Error>

Given a local tracking_branch name, find the remote that maps to it along with the name of the branch on +the side of the remote, also called upstream branch.

+

Return Ok(None) if there is no remote with fetch-refspecs that would match tracking_branch on the right-hand side, +or Err if the matches were ambiguous.

+
§Limitations
+

A single valid mapping is required as fine-grained matching isn’t implemented yet. This means that

+
Source

pub fn branch_remote_name<'a>( + &self, + short_branch_name: impl Into<&'a BStr>, + direction: Direction, +) -> Option<Name<'_>>

Returns the unvalidated name of the remote associated with the given short_branch_name, +typically main instead of refs/heads/main. +In some cases, the returned name will be an URL. +Returns None if the remote was not found or if the name contained illformed UTF-8.

+
    +
  • if direction is remote::Direction::Fetch, we will query the branch.<short_name>.remote configuration.
    • +
  • if direction is remote::Direction::Push, the push remote will be queried by means of branch.<short_name>.pushRemote +or remote.pushDefault as fallback.
    • +
+

See also Reference::remote_name() for a more typesafe version +to be used when a Reference is available.

+

short_branch_name can typically be obtained by shortening a full branch name.

+
Source

pub fn branch_remote<'a>( + &self, + short_branch_name: impl Into<&'a BStr>, + direction: Direction, +) -> Option<Result<Remote<'_>, Error>>

Like branch_remote_name(…), but returns a Remote. +short_branch_name is the name to use for looking up branch.<short_branch_name>.* values in the +configuration.

+

See also Reference::remote().

+
Source§

impl Repository

Query configuration related to remotes.

+
Source

pub fn remote_names(&self) -> Names<'_>

Returns a sorted list unique of symbolic names of remotes that +we deem trustworthy.

+
Source

pub fn remote_default_name(&self, direction: Direction) -> Option<Cow<'_, BStr>>

Obtain the branch-independent name for a remote for use in the given direction, or None if it could not be determined.

+

For fetching, use the only configured remote, or default to origin if it exists. +For pushing, use the remote.pushDefault trusted configuration key, or fall back to the rules for fetching.

+
§Notes
+

It’s up to the caller to determine what to do if the current head is unborn or detached.

+
Source§

impl Repository

Source

pub fn transport_options<'a>( + &self, + url: impl Into<&'a BStr>, + remote_name: Option<&BStr>, +) -> Result<Option<Box<dyn Any>>, Error>

Available on crate features blocking-network-client or async-network-client only.

Produce configuration suitable for url, as differentiated by its protocol/scheme, to be passed to a transport instance via +configure() (via &**config to pass the contained Any and not the Box). +None is returned if there is no known configuration. If remote_name is not None, the remote’s name may contribute to +configuration overrides, typically for the HTTP transport.

+

Note that the caller may cast the instance themselves to modify it before passing it on.

+

For transports that support proxy authentication, the +default authentication method will be used with the url of the proxy +if it contains a user name.

impl Repository

General Configuration

+
Source

pub fn config_snapshot(&self) -> Snapshot<'_>

Return a snapshot of the configuration as seen upon opening the repository.

+
Source

pub fn config_snapshot_mut(&mut self) -> SnapshotMut<'_>

Return a mutable snapshot of the configuration as seen upon opening the repository, starting a transaction. +When the returned instance is dropped, it is applied in full, even if the reason for the drop is an error.

+

Note that changes to the configuration are in-memory only and are observed only this instance +of the Repository.

+
Source

pub fn filesystem_options(&self) -> Result<Capabilities, Error>

Return filesystem options as retrieved from the repository configuration.

+

Note that these values have not been probed.

+
Source

pub fn stat_options(&self) -> Result<Options, Error>

Available on crate feature index only.

Return filesystem options on how to perform stat-checks, typically in relation to the index.

+

Note that these values have not been probed.

+
Source

pub fn open_options(&self) -> &Options

The options used to open the repository.

+
Source

pub fn big_file_threshold(&self) -> Result<u64, Error>

Return the big-file threshold above which Git will not perform a diff anymore or try to delta-diff packs, +as configured by core.bigFileThreshold, or the default value.

+
Source

pub fn ssh_connect_options(&self) -> Result<Options, Error>

Available on crate feature blocking-network-client only.

Obtain options for use when connecting via ssh.

+
Source

pub fn command_context(&self) -> Result<Context, Error>

Available on crate feature attributes only.

Return the context to be passed to any spawned program that is supposed to interact with the repository, like +hooks or filters.

pub fn object_hash(&self) -> Kind

The kind of object hash the repository is configured to use.

+
Source

pub fn diff_algorithm(&self) -> Result<Algorithm, Error>

Available on crate feature blob-diff only.

Return the algorithm to perform diffs or merges with.

+

In case of merges, a diff is performed under the hood in order to learn which hunks need merging.

impl Repository

Diff-utilities

+
Source

pub fn diff_resource_cache( + &self, + mode: Mode, + worktree_roots: WorktreeRoots, +) -> Result<Platform, Error>

Available on crate feature blob-diff only.

Create a resource cache for diffable objects, and configured with everything it needs to know to perform diffs +faithfully just like git would. +mode controls what version of a resource should be diffed. +worktree_roots determine if files can be read from the worktree, where each side of the diff operation can +be represented by its own worktree root. .gitattributes are automatically read from the worktree if at least +one worktree is present.

+

Note that attributes will always be obtained from the current HEAD index even if the resources being diffed +might live in another tree. Further, if one of the worktree_roots are set, attributes will also be read from +the worktree. Otherwise, it will be skipped and attributes are read from the index tree instead.

+
Source

pub fn diff_tree_to_tree<'a, 'old_repo: 'a, 'new_repo: 'a>( + &self, + old_tree: impl Into<Option<&'a Tree<'old_repo>>>, + new_tree: impl Into<Option<&'a Tree<'new_repo>>>, + options: impl Into<Option<Options>>, +) -> Result<Vec<ChangeDetached>, Error>

Available on crate feature blob-diff only.

Produce the changes that would need to be applied to old_tree to create new_tree. +If options are unset, they will be filled in according to the git configuration of this repository, and with +full paths being tracked as well, which typically means that +rewrite tracking might be disabled if done so explicitly by the user. +If options are set, the user can take full control over the settings.

+

Note that this method exists to evoke similarity to git2, and makes it easier to fully control diff settings. +A more fluent version may be used as well.

+
Source

pub fn diff_resource_cache_for_tree_diff(&self) -> Result<Platform, Error>

Available on crate feature blob-diff only.

Return a resource cache suitable for diffing blobs from trees directly, where no worktree checkout exists.

+

For more control, see diff_resource_cache().

Source

pub fn dirwalk_options(&self) -> Result<Options, Error>

Available on crate feature dirwalk only.

Return default options suitable for performing a directory walk on this repository.

+

Used in conjunction with dirwalk()

+
Source

pub fn dirwalk( + &self, + index: &State, + patterns: impl IntoIterator<Item = impl AsRef<BStr>>, + should_interrupt: &AtomicBool, + options: Options, + delegate: &mut dyn Delegate, +) -> Result<Outcome<'_>, Error>

Available on crate feature dirwalk only.

Perform a directory walk configured with options under control of the delegate. Use patterns to +further filter entries. should_interrupt is polled to see if an interrupt is requested, causing an +error to be returned instead.

+

The index is used to determine if entries are tracked, and for excludes and attributes +lookup. Note that items will only count as tracked if they have the gix_index::entry::Flags::UPTODATE +flag set.

+

Note that dirwalks for the purpose of deletion will be initialized with the worktrees of this repository +if they fall into the working directory of this repository as well to mark them as tracked. That way +it’s hard to accidentally flag them for deletion. +This is intentionally not the case when deletion is not intended so they look like +untracked repositories instead.

+

See gix_dir::walk::delegate::Collect for a delegate that collects all seen entries.

+
Source

pub fn dirwalk_iter( + &self, + index: impl Into<IndexPersistedOrInMemory>, + patterns: impl IntoIterator<Item = impl Into<BString>>, + should_interrupt: OwnedOrStaticAtomicBool, + options: Options, +) -> Result<Iter, Error>

Available on crate feature dirwalk only.

Create an iterator over a running traversal, which stops if the iterator is dropped. All arguments +are the same as in dirwalk().

+

should_interrupt should be set to Default::default() if it is supposed to be unused. +Otherwise, it can be created by passing a &'static AtomicBool, &Arc<AtomicBool> or Arc<AtomicBool>.

+

impl Repository

Source

pub fn filter_pipeline( + &self, + tree_if_bare: Option<ObjectId>, +) -> Result<(Pipeline<'_>, IndexPersistedOrInMemory), Error>

Available on crate feature attributes only.

Configure a pipeline for converting byte buffers to the worktree representation, and byte streams to the git-internal +representation. Also return the index that was used when initializing the pipeline as it may be useful when calling +convert_to_git(). +Bare repositories will either use HEAD^{tree} for accessing all relevant worktree files or the given tree_if_bare.

+

Note that this is considered a primitive as it operates on data directly and will not have permanent effects. +We also return the index that was used to configure the attributes cache (for accessing .gitattributes), which can be reused +after it was possibly created from a tree, an expensive operation.

+
§Performance
+

Note that when in a repository with worktree, files in the worktree will be read with priority, which causes at least a stat +each time the directory is changed. This can be expensive if access isn’t in sorted order, which would cause more then necessary +stats: one per directory.

+
Source§

impl Repository

Freelist configuration

+

The free-list is an internal and ‘transparent’ mechanism for obtaining and re-using memory buffers when +reading objects. That way, trashing is avoided as buffers are re-used and re-written.

+

However, there are circumstances when releasing memory early is preferred, for instance on the server side.

+

Also note that the free-list isn’t cloned, so each clone of this instance starts with an empty one.

+
Source

pub fn empty_reusable_buffer(&self) -> Buffer<'_>

Return an empty buffer which is tied to this repository instance, and reuse its memory allocation by +keeping it around even after it drops.

+
Source

pub fn set_freelist( + &mut self, + list: Option<Vec<Vec<u8>>>, +) -> Option<Vec<Vec<u8>>>

Set the currently used freelist to list. If None, it will be disabled entirely.

+

Return the currently previously allocated free-list, a list of reusable buffers typically used when reading objects. +May be None if there was no free-list.

+
Source

pub fn without_freelist(self) -> Self

A builder method to disable the free-list on a newly created instance.

pub fn revision_graph<'cache, T>( + &self, + cache: Option<&'cache Graph>, +) -> Graph<'_, 'cache, T>

Create a graph data-structure capable of accelerating graph traversals and storing state of type T with each commit +it encountered.

+

Note that the cache will be used if present, and it’s best obtained with +commit_graph_if_enabled().

+

Note that a commitgraph is only allowed to be used if core.commitGraph is true (the default), and that configuration errors are +ignored as well.

+
§Performance
+

Note that the Graph can be sensitive to various object database settings that may affect the performance +of the commit walk.

+
Source

pub fn commit_graph(&self) -> Result<Graph, Error>

Return a cache for commits and their graph structure, as managed by git commit-graph, for accelerating commit walks on +a low level.

+

Note that revision_graph() should be preferred for general purpose walks that don’t +rely on the actual commit cache to be present, while leveraging the commit-graph if possible.

+
Source

pub fn commit_graph_if_enabled(&self) -> Result<Option<Graph>, Error>

Return a newly opened commit-graph if it is available and enabled in the Git configuration.

+
Source§

impl Repository

Identity handling.

+

§Deviation

+

There is no notion of a default user like in git, and instead failing to provide a user +is fatal. That way, we enforce correctness and force application developers to take care +of this issue which can be done in various ways, for instance by setting +gitoxide.committer.nameFallback and similar.

+
Source

pub fn committer(&self) -> Option<Result<SignatureRef<'_>, Error>>

Return the committer as configured by this repository, which is determined by…

+
    +
  • …the git configuration committer.name|email…
    • +
  • …the GIT_COMMITTER_(NAME|EMAIL|DATE) environment variables…
    • +
  • …the configuration for user.name|email as fallback…
    • +
+

…and in that order, or None if no committer name or email was configured, or Some(Err(…)) +if the committer date could not be parsed.

+
§Note
+

The values are cached when the repository is instantiated.

+
Source

pub fn author(&self) -> Option<Result<SignatureRef<'_>, Error>>

Return the author as configured by this repository, which is determined by…

+
    +
  • …the git configuration author.name|email…
    • +
  • …the GIT_AUTHOR_(NAME|EMAIL|DATE) environment variables…
    • +
  • …the configuration for user.name|email as fallback…

Index access

+
Source

pub fn open_index(&self) -> Result<File, Error>

Available on crate feature index only.

Open a new copy of the index file and decode it entirely.

+

It will use the index.threads configuration key to learn how many threads to use. +Note that it may fail if there is no index.

+
Source

pub fn index(&self) -> Result<Index, Error>

Available on crate feature index only.

Return a shared worktree index which is updated automatically if the in-memory snapshot has become stale as the underlying file +on disk has changed.

+
§Notes
+
    +
  • This will fail if the file doesn’t exist, like in a newly initialized repository. If that is the case, use +index_or_empty() or try_index() instead.
    • +
+

The index file is shared across all clones of this repository.

Source

pub fn index_or_empty(&self) -> Result<Index, Error>

Available on crate feature index only.

Return the shared worktree index if present, or return a new empty one which has an association to the place where the index would be.

+
Source

pub fn try_index(&self) -> Result<Option<Index>, Error>

Available on crate feature index only.

Return a shared worktree index which is updated automatically if the in-memory snapshot has become stale as the underlying file +on disk has changed, or None if no such file exists.

+

The index file is shared across all clones of this repository.

Source

pub fn index_or_load_from_head(&self) -> Result<IndexPersistedOrInMemory, Error>

Available on crate feature index only.

Open the persisted worktree index or generate it from the current HEAD^{tree} to live in-memory only.

+

Use this method to get an index in any repository, even bare ones that don’t have one naturally.

+
§Note
+
    +
  • The locally stored index is not guaranteed to represent HEAD^{tree} if this repository is bare - bare repos +don’t naturally have an index and if an index is present it must have been generated by hand.
    • +
  • This method will fail on unborn repositories as HEAD doesn’t point to a reference yet, which is needed to resolve +the revspec. If that is a concern, use Self::index_or_load_from_head_or_empty() instead.
    • +
+
Source

pub fn index_or_load_from_head_or_empty( + &self, +) -> Result<IndexPersistedOrInMemory, Error>

Available on crate feature index only.

Open the persisted worktree index or generate it from the current HEAD^{tree} to live in-memory only, +or resort to an empty index if HEAD is unborn.

+

Use this method to get an index in any repository, even bare ones that don’t have one naturally, or those +that are in a state where HEAD is invalid or points to an unborn reference.

+
Source

pub fn index_from_tree(&self, tree: &oid) -> Result<File, Error>

Available on crate feature index only.

Create new index-file, which would live at the correct location, in memory from the given tree.

Source

pub fn git_dir_trust(&self) -> Trust

The trust we place in the git-dir, with lower amounts of trust causing access to configuration to be limited. +Note that if the git-dir is trusted but the worktree is not, the result is that the git-dir is also less trusted.

+
Source

pub fn current_dir(&self) -> &Path

Return the current working directory as present during the instantiation of this repository.

Source

pub fn prefix(&self) -> Result<Option<&Path>, Error>

Returns the relative path which is the components between the working tree and the current working dir (CWD). +Note that it may be None if there is no work tree, or if CWD isn’t inside of the working tree directory.

pub fn open_mailmap(&self) -> Snapshot

Available on crate feature mailmap only.

Similar to open_mailmap_into(), but ignores all errors and returns at worst +an empty mailmap, e.g. if there is no mailmap or if there were errors loading them.

+

This represents typical usage within git, which also works with what’s there without considering a populated mailmap +a reason to abort an operation, considering it optional.

+
Source

pub fn open_mailmap_into(&self, target: &mut Snapshot) -> Result<(), Error>

Available on crate feature mailmap only.

Try to merge mailmaps from the following locations into target:

+
    +
  • read the .mailmap file without following symlinks from the working tree, if present
    • +
  • OR read HEAD:.mailmap if this repository is bare (i.e. has no working tree), if the mailmap.blob is not set.
    • +
  • read the mailmap as configured in mailmap.blob, if set.
    • +
  • read the file as configured by mailmap.file, following symlinks, if set.

Source

pub fn merge_resource_cache( + &self, + worktree_roots: WorktreeRoots, +) -> Result<Platform, Error>

Available on crate feature merge only.

Create a resource cache that can hold the three resources needed for a three-way merge. worktree_roots +determines which side of the merge is read from the worktree, or from which worktree.

The platform can be used to set up resources and finally perform a merge among blobs.

+

Note that the current index is used for attribute queries.

Available on crate feature merge only.

Merge our_tree and their_tree together, assuming they have the same ancestor_tree, to yield a new tree +which is provided as tree editor to inspect and finalize results at will. +No change to the worktree or index is made, but objects may be written to the object database as merge results +are stored. +If these changes should not be observable outside of this instance, consider enabling object memory.

+

Note that ancestor_tree can be the empty tree hash to indicate no common ancestry.

+

labels are typically chosen to identify the refs or names for our_tree and their_tree and ancestor_tree respectively.

+

options should be initialized with tree_merge_options().

+
§Performance

pub fn merge_commits( + &self, + our_commit: impl Into<ObjectId>, + their_commit: impl Into<ObjectId>, + labels: Labels<'_>, + options: Options, +) -> Result<Outcome<'_>, Error>

Available on crate feature merge only.

Merge our_commit and their_commit together to yield a new tree which is provided as tree editor +to inspect and finalize results at will. The merge-base will be determined automatically between both commits, along with special +handling in case there are multiple merge-bases. +No change to the worktree or index is made, but objects may be written to the object database as merge results +are stored. +If these changes should not be observable outside of this instance, consider enabling object memory.

pub fn virtual_merge_base( + &self, + merge_bases: impl IntoIterator<Item = impl Into<ObjectId>>, + options: Options, +) -> Result<Outcome<'_>, Error>

Available on crate feature merge only.

Create a single virtual merge-base by merging all merge_bases into one. +If the list is empty, an error will be returned as the histories are then unrelated. +If there is only one commit in the list, it is returned directly with this case clearly marked in the outcome.

+

Note that most of options are overwritten to match the requirements of a merge-base merge, but they can be useful +to control the diff algorithm or rewrite tracking, for example.

Find objects of various kins

+
Source

pub fn find_object(&self, id: impl Into<ObjectId>) -> Result<Object<'_>, Error>

Find the object with id in the object database or return an error if it could not be found.

+

There are various legitimate reasons for an object to not be present, which is why +try_find_object(…) might be preferable instead.

+
§Performance Note
+

In order to get the kind of the object, is must be fully decoded from storage if it is packed with deltas. +Loose object could be partially decoded, even though that’s not implemented.

Source

pub fn find_commit(&self, id: impl Into<ObjectId>) -> Result<Commit<'_>, Error>

Find a commit with id or fail if there was no object or the object wasn’t a commit.

Source

pub fn find_header(&self, id: impl Into<ObjectId>) -> Result<Header, Error>

Obtain information about an object without fully decoding it, or fail if the object doesn’t exist.

+

Note that despite being cheaper than Self::find_object(), there is still some effort traversing delta-chains.

+
Source

pub fn has_object(&self, id: impl AsRef<oid>) -> bool

Return true if id exists in the object database.

+
§Performance
+

This method can be slow if the underlying object database has +an unsuitable RefreshMode and id is not likely to exist. +Use repo.objects.refresh_never() to avoid expensive +IO-bound refreshes if an object wasn’t found.

+
Source

pub fn try_find_header( + &self, + id: impl Into<ObjectId>, +) -> Result<Option<Header>, Error>

Obtain information about an object without fully decoding it, or None if the object doesn’t exist.

Source

pub fn write_object(&self, object: impl WriteTo) -> Result<Id<'_>, Error>

Write the given object into the object database and return its object id.

Source

pub fn write_blob(&self, bytes: impl AsRef<[u8]>) -> Result<Id<'_>, Error>

Write a blob from the given bytes.

We avoid writing duplicate objects to slow disks that will eventually have to be garbage collected by +pre-hashing the data, and checking if the object is already present.

+
Source

pub fn write_blob_stream(&self, bytes: impl Read) -> Result<Id<'_>, Error>

Write a blob from the given Read implementation.

Create a tag reference named name (without refs/tags/ prefix) pointing to a newly created tag object +which in turn points to target and return the newly created reference.

+

It will be created with constraint which is most commonly to only create it +or to force overwriting a possibly existing tag.

+
Source

pub fn commit_as<'a, 'c, Name, E>( + &self, + committer: impl Into<SignatureRef<'c>>, + author: impl Into<SignatureRef<'a>>, + reference: Name, + message: impl AsRef<str>, + tree: impl Into<ObjectId>, + parents: impl IntoIterator<Item = impl Into<ObjectId>>, +) -> Result<Id<'_>, Error>
where + Name: TryInto<FullName, Error = E>, + Error: From<E>,

Similar to commit(…), but allows to create the commit with committer and author specified.

+

This forces setting the commit time and author time by hand. Note that typically, committer and author are the same.

+
Source

pub fn commit<Name, E>( + &self, + reference: Name, + message: impl AsRef<str>, + tree: impl Into<ObjectId>, + parents: impl IntoIterator<Item = impl Into<ObjectId>>, +) -> Result<Id<'_>, Error>
where + Name: TryInto<FullName, Error = E>, + Error: From<E>,

Create a new commit object with message referring to tree with parents, and point reference +to it. The commit is written without message encoding field, which can be assumed to be UTF-8. +author and committer fields are pre-set from the configuration, which can be altered +temporarily before the call if required.

+

reference will be created if it doesn’t exist, and can be "HEAD" to automatically write-through to the symbolic reference +that HEAD points to if it is not detached. For this reason, detached head states cannot be created unless the HEAD is detached +already. The reflog will be written as canonical git would do, like <operation> (<detail>): <summary>.

+

The first parent id in parents is expected to be the current target of reference and the operation will fail if it is not. +If there is no parent, the reference is expected to not exist yet.

+

The method fails immediately if a reference lock can’t be acquired.

+
§Writing a commit without reference update

If the reference shouldn’t be updated, use Self::write_object() along with a newly created crate::objs::Object whose fields +can be fully defined.

pub fn empty_tree(&self) -> Tree<'_>

Return an empty tree object, suitable for getting changes.

Create a new pathspec abstraction that allows to conduct searches using patterns. +inherit_ignore_case should be true if patterns will match against files on disk, or false otherwise, for more natural matching +(but also note that git does not do that). +index may be needed to load attributes which is required only if patterns refer to attributes via :(attr:…) syntax. +In the same vein, attributes_source affects where .gitattributes files are read from if pathspecs need to match against attributes. +If empty_patterns_match_prefix is true, then even empty patterns will match only what’s inside of the prefix. Otherwise +they will match everything.

+

It will be initialized exactly how it would, and attribute matching will be conducted by reading the worktree first if available. +If that is not desirable, consider calling Pathspec::new() directly.

+
Source

pub fn pathspec_defaults(&self) -> Result<Defaults, Error>

Available on crate feature attributes only.

Return default settings that are required when parsing pathspecs by hand.

+

These are stemming from environment variables which have been converted to config settings, +which now serve as authority for configuration.

+
Source

pub fn pathspec_defaults_inherit_ignore_case( + &self, + inherit_ignore_case: bool, +) -> Result<Defaults, Error>

Available on crate feature attributes only.

Similar to Self::pathspec_defaults(), but will automatically configure the returned defaults to match case-insensitively if the underlying +filesystem is also configured to be case-insensitive according to core.ignoreCase, and inherit_ignore_case is true.

+

impl Repository

Obtain and alter references comfortably

+
Source

pub fn tag_reference( + &self, + name: impl AsRef<str>, + target: impl Into<ObjectId>, + constraint: PreviousValue, +) -> Result<Reference<'_>, Error>

Create a lightweight tag with given name (and without refs/tags/ prefix) pointing to the given target, and return it as reference.

+

It will be created with constraint which is most commonly to only create it +or to force overwriting a possibly existing tag.

+
Source

pub fn namespace(&self) -> Option<&Namespace>

Returns the currently set namespace for references, or None if it is not set.

+

Namespaces allow to partition references, and is configured per Easy.

+
Source

pub fn clear_namespace(&mut self) -> Option<Namespace>

Remove the currently set reference namespace and return it, affecting only this Easy.

Source

pub fn set_namespace<'a, Name, E>( + &mut self, + namespace: Name, +) -> Result<Option<Namespace>, Error>
where + Name: TryInto<&'a PartialNameRef, Error = E>, + Error: From<E>,

Set the reference namespace to the given value, like "foo" or "foo/bar".

+

Note that this value is shared across all Easy… instances as the value is stored in the shared Repository.

+
Source

pub fn reference<Name, E>( + &self, + name: Name, + target: impl Into<ObjectId>, + constraint: PreviousValue, + log_message: impl Into<BString>, +) -> Result<Reference<'_>, Error>
where + Name: TryInto<FullName, Error = E>, + Error: From<E>,

Create a new reference with name, like refs/heads/branch, pointing to target, adhering to constraint +during creation and writing log_message into the reflog. Note that a ref-log will be written even if log_message is empty.

+

The newly created Reference is returned.

+
Source

pub fn edit_reference(&self, edit: RefEdit) -> Result<Vec<RefEdit>, Error>

Edit a single reference as described in edit, and write reference logs as log_committer.

+

One or more RefEdits are returned - symbolic reference splits can cause more edits to be performed. All edits have the previous +reference values set to the ones encountered at rest after acquiring the respective reference’s lock.

+
Source

pub fn edit_references( + &self, + edits: impl IntoIterator<Item = RefEdit>, +) -> Result<Vec<RefEdit>, Error>

Edit one or more references as described by their edits. +Note that one can set the committer name for use in the ref-log by temporarily +overriding the git-config, or use +edit_references_as(committer) for convenience.

+

Returns all reference edits, which might be more than where provided due the splitting of symbolic references, and +whose previous (old) values are the ones seen on in storage after the reference was locked.

+
Source

pub fn edit_references_as( + &self, + edits: impl IntoIterator<Item = RefEdit>, + committer: Option<SignatureRef<'_>>, +) -> Result<Vec<RefEdit>, Error>

A way to apply reference edits similar to edit_references(…), but set a specific +commiter for use in the reflog. It can be None if it’s the purpose edits are configured to not update the +reference log, or cause a failure otherwise.

+
Source

pub fn head(&self) -> Result<Head<'_>, Error>

Return the repository head, an abstraction to help dealing with the HEAD reference.

+

The HEAD reference can be in various states, for more information, the documentation of Head.

+
Source

pub fn head_id(&self) -> Result<Id<'_>, Error>

Resolve the HEAD reference, follow and peel its target and obtain its object id, +following symbolic references and tags until a commit is found.

+

Note that this may fail for various reasons, most notably because the repository +is freshly initialized and doesn’t have any commits yet.

+

Also note that the returned id is likely to point to a commit, but could also +point to a tree or blob. It won’t, however, point to a tag as these are always peeled.

+
Source

pub fn head_name(&self) -> Result<Option<FullName>, Error>

Return the name to the symbolic reference HEAD points to, or None if the head is detached.

+

The difference to head_ref() is that the latter requires the reference to exist, +whereas here we merely return a the name of the possibly unborn reference.

+
Source

pub fn head_ref(&self) -> Result<Option<Reference<'_>>, Error>

Return the reference that HEAD points to, or None if the head is detached or unborn.

+
Source

pub fn head_commit(&self) -> Result<Commit<'_>, Error>

Return the commit object the HEAD reference currently points to after peeling it fully, +following symbolic references and tags until a commit is found.

+

Note that this may fail for various reasons, most notably because the repository +is freshly initialized and doesn’t have any commits yet. It could also fail if the +head does not point to a commit.

+
Source

pub fn head_tree_id(&self) -> Result<Id<'_>, Error>

Return the tree id the HEAD reference currently points to after peeling it fully, +following symbolic references and tags until a commit is found.

+

Note that this may fail for various reasons, most notably because the repository +is freshly initialized and doesn’t have any commits yet. It could also fail if the +head does not point to a commit.

+
Source

pub fn head_tree_id_or_empty(&self) -> Result<Id<'_>, Error>

Like Self::head_tree_id(), but will return an empty tree hash if the repository HEAD is unborn.

+
Source

pub fn head_tree(&self) -> Result<Tree<'_>, Error>

Return the tree object the HEAD^{tree} reference currently points to after peeling it fully, +following symbolic references and tags until a tree is found.

+

Note that this may fail for various reasons, most notably because the repository +is freshly initialized and doesn’t have any commits yet. It could also fail if the +head does not point to a tree, unlikely but possible.

+
Source

pub fn find_reference<'a, Name, E>( + &self, + name: Name, +) -> Result<Reference<'_>, Error>
where + Name: TryInto<&'a PartialNameRef, Error = E> + Clone, + Error: From<E>,

Find the reference with the given partial or full name, like main, HEAD, heads/branch or origin/other, +or return an error if it wasn’t found.

+

Consider try_find_reference(…) if the reference might not exist +without that being considered an error.

+
Source

pub fn references(&self) -> Result<Platform<'_>, Error>

Return a platform for iterating references.

+

Common kinds of iteration are all or prefixed +references.

Source

pub fn try_find_reference<'a, Name, E>( + &self, + name: Name, +) -> Result<Option<Reference<'_>>, Error>
where + Name: TryInto<&'a PartialNameRef, Error = E>, + Error: From<E>,

Try to find the reference named name, like main, heads/branch, HEAD or origin/other, and return it.

+

Otherwise return None if the reference wasn’t found. +If the reference is expected to exist, use find_reference().

pub fn remote_at<Url, E>(&self, url: Url) -> Result<Remote<'_>, Error>
where + Url: TryInto<Url, Error = E>, + Error: From<E>,

Create a new remote available at the given url.

+

It’s configured to fetch included tags by default, similar to git. +See with_fetch_tags(…) for a way to change it.

+
Source

pub fn remote_at_without_url_rewrite<Url, E>( + &self, + url: Url, +) -> Result<Remote<'_>, Error>
where + Url: TryInto<Url, Error = E>, + Error: From<E>,

Create a new remote available at the given url similarly to remote_at(), +but don’t rewrite the url according to rewrite rules. +This eliminates a failure mode in case the rewritten URL is faulty, allowing to selectively apply rewrite +rules later and do so non-destructively.

+
Source

pub fn find_remote<'a>( + &self, + name_or_url: impl Into<&'a BStr>, +) -> Result<Remote<'_>, Error>

Find the configured remote with the given name_or_url or report an error, +similar to try_find_remote(…).

+

Note that we will obtain remotes only if we deem them trustworthy.

+
Source

pub fn find_default_remote( + &self, + direction: Direction, +) -> Option<Result<Remote<'_>, Error>>

Find the default remote as configured, or None if no such configuration could be found.

+

See remote_default_name() for more information on the direction parameter.

+
Source

pub fn try_find_remote<'a>( + &self, + name_or_url: impl Into<&'a BStr>, +) -> Option<Result<Remote<'_>, Error>>

Find the configured remote with the given name_or_url or return None if it doesn’t exist, +for the purpose of fetching or pushing data.

+

There are various error kinds related to partial information or incorrectly formatted URLs or ref-specs. +Also note that the created Remote may have neither fetch nor push ref-specs set at all.

+

Note that ref-specs are de-duplicated right away which may change their order. This doesn’t affect matching in any way +as negations/excludes are applied after includes.

+

We will only include information if we deem it trustworthy.

+
Source

pub fn find_fetch_remote( + &self, + name_or_url: Option<&BStr>, +) -> Result<Remote<'_>, Error>

This method emulate what git fetch <remote> does in order to obtain a remote to fetch from.

+

As such, with name_or_url being Some, it will:

+
    +
  • use name_or_url verbatim if it is a URL, creating a new remote in memory as needed.
    • +
  • find the named remote if name_or_url is a remote name
    • +
+

If name_or_url is None:

+
    +
  • use the current HEAD branch to find a configured remote
    • +
  • fall back to either a generally configured remote or the only configured remote.
    • +
+

Fail if no remote could be found despite all of the above.

+
Source

pub fn try_find_remote_without_url_rewrite<'a>( + &self, + name_or_url: impl Into<&'a BStr>, +) -> Option<Result<Remote<'_>, Error>>

Similar to try_find_remote(), but removes a failure mode if rewritten URLs turn out to be invalid +as it skips rewriting them. +Use this in conjunction with Remote::rewrite_urls() to non-destructively apply the rules and keep the failed urls unchanged.

Source

pub fn rev_parse<'a>( + &self, + spec: impl Into<&'a BStr>, +) -> Result<Spec<'_>, Error>

Available on crate feature revision only.

Parse a revision specification and turn it into the object(s) it describes, similar to git rev-parse.

+
§Deviation
+
    +
  • @ actually stands for HEAD, whereas git resolves it to the object pointed to by HEAD without making the +HEAD ref available for lookups.
    • +
+
Source

pub fn rev_parse_single<'repo, 'a>( + &'repo self, + spec: impl Into<&'a BStr>, +) -> Result<Id<'repo>, Error>

Available on crate feature revision only.

Parse a revision specification and return single object id as represented by this instance.

+
Source

pub fn merge_base( + &self, + one: impl Into<ObjectId>, + two: impl Into<ObjectId>, +) -> Result<Id<'_>, Error>

Available on crate feature revision only.

Obtain the best merge-base between commit one and two, or fail if there is none.

For repeated calls, prefer merge_base_with_cache(). +Also be sure to set an object cache to accelerate repeated commit lookups.

+
Source

pub fn merge_base_with_graph( + &self, + one: impl Into<ObjectId>, + two: impl Into<ObjectId>, + graph: &mut Graph<'_, '_, Commit<Flags>>, +) -> Result<Id<'_>, Error>

Available on crate feature revision only.

Obtain the best merge-base between commit one and two, or fail if there is none, providing a +commit-graph graph to potentially greatly accelerate the operation by reusing graphs from previous runs.

+
§Performance
+

Be sure to set an object cache to accelerate repeated commit lookups.

Source

pub fn merge_bases_many_with_graph( + &self, + one: impl Into<ObjectId>, + others: &[ObjectId], + graph: &mut Graph<'_, '_, Commit<Flags>>, +) -> Result<Vec<Id<'_>>, Error>

Available on crate feature revision only.

Obtain all merge-bases between commit one and others, or an empty list if there is none, providing a +commit-graph graph to potentially greatly accelerate the operation.

+
§Performance

Source

pub fn merge_base_octopus_with_graph( + &self, + commits: impl IntoIterator<Item = impl Into<ObjectId>>, + graph: &mut Graph<'_, '_, Commit<Flags>>, +) -> Result<Id<'_>, Error>

Available on crate feature revision only.

Return the best merge-base among all commits, or fail if commits yields no commit or no merge-base was found.

+

Use graph to speed up repeated calls.

Source

pub fn merge_base_octopus( + &self, + commits: impl IntoIterator<Item = impl Into<ObjectId>>, +) -> Result<Id<'_>, Error>

Available on crate feature revision only.

Return the best merge-base among all commits, or fail if commits yields no commit or no merge-base was found.

Source

pub fn rev_walk( + &self, + tips: impl IntoIterator<Item = impl Into<ObjectId>>, +) -> Platform<'_>

Create the baseline for a revision walk by initializing it with the tips to start iterating on.

impl Repository

Source

pub fn is_shallow(&self) -> bool

Return true if the repository is a shallow clone, i.e. contains history only up to a certain depth.

+
Source

pub fn shallow_commits(&self) -> Result<Option<Commits>, Error>

Return a shared list of shallow commits which is updated automatically if the in-memory snapshot has become stale +as the underlying file on disk has changed.

+

The list of shallow commits represents the shallow boundary, beyond which we are lacking all (parent) commits. +Note that the list is never empty, as Ok(None) is returned in that case indicating the repository +isn’t a shallow clone.

+

The shared list is shared across all clones of this repository.

+
Source

pub fn shallow_file(&self) -> PathBuf

Return the path to the shallow file which contains hashes, one per line, that describe commits that don’t have their +parents within this repository.

+

Note that it may not exist if the repository isn’t actually shallow.

pub fn state(&self) -> Option<InProgress>

Returns the status of an in progress operation on a repository or None +if no operation is currently in progress.

pub fn open_modules_file(&self) -> Result<Option<File>, Error>

Available on crate feature attributes only.

Open the .gitmodules file as present in the worktree, or return None if no such file is available. +Note that git configuration is also contributing to the result based on the current snapshot.

+

Note that his method will not look in other places, like the index or the HEAD tree.

+
Source

pub fn modules(&self) -> Result<Option<ModulesSnapshot>, Error>

Available on crate feature attributes only.

Return a shared .gitmodules file which is updated automatically if the in-memory snapshot +has become stale as the underlying file on disk has changed. The snapshot based on the file on disk is shared across all +clones of this repository.

+

If a file on disk isn’t present, we will try to load it from the index, and finally from the current tree. +In the latter two cases, the result will not be cached in this repository instance as we can’t detect freshness anymore, +so time this method is called a new modules file will be created.

+

Note that git configuration is also contributing to the result based on the current snapshot.

+
Source

pub fn submodules( + &self, +) -> Result<Option<impl Iterator<Item = Submodule<'_>>>, Error>

Available on crate feature attributes only.

Return the list of available submodules, or None if there is no submodule configuration.

Source§

impl Repository

Interact with individual worktrees and their information.

+
Source

pub fn worktrees(&self) -> Result<Vec<Proxy<'_>>>

Return a list of all linked worktrees sorted by private git dir path as a lightweight proxy.

+

This means the number is 0 even if there is the main worktree, as it is not counted as linked worktree. +This also means it will be 1 if there is one linked worktree next to the main worktree. +It’s worth noting that a bare repository may have one or more linked worktrees, but has no main worktree, +which is the reason why the possibly available main worktree isn’t listed here.

+

Note that these need additional processing to become usable, but provide a first glimpse a typical worktree information.

+
Source

pub fn main_repo(&self) -> Result<Repository, Error>

Return the repository owning the main worktree, typically from a linked worktree.

+

Note that it might be the one that is currently open if this repository doesn’t point to a linked worktree. +Also note that the main repo might be bare.

+
Source

pub fn worktree(&self) -> Option<Worktree<'_>>

Return the currently set worktree if there is one, acting as platform providing a validated worktree base path.

+

Note that there would be None if this repository is bare and the parent Repository was instantiated without +registered worktree in the current working dir, even if no .git file or directory exists. +It’s merely based on configuration, see Worktree::dot_git_exists() for a way to perform more validation.

+
Source

pub fn is_bare(&self) -> bool

Return true if this repository is bare, and has no main work tree.

+

This is not to be confused with the worktree() worktree, which may exists if this instance +was opened in a worktree that was created separately.

+
Source

pub fn worktree_stream( + &self, + id: impl Into<ObjectId>, +) -> Result<(Stream, File), Error>

Available on crate feature worktree-stream only.

If id points to a tree, produce a stream that yields one worktree entry after the other. The index of the tree at id +is returned as well as it is an intermediate byproduct that might be useful to callers.

+

The entries will look exactly like they would if one would check them out, with filters applied. +The export-ignore attribute is used to skip blobs or directories to which it applies.

+
Source

pub fn worktree_archive( + &self, + stream: Stream, + out: impl Write + Seek, + blobs: impl Count, + should_interrupt: &AtomicBool, + options: Options, +) -> Result<(), Error>

Available on crate feature worktree-archive only.

Produce an archive from the stream and write it to out according to options. +Use blob to provide progress for each entry written to out, and note that it should already be initialized to the amount +of expected entries, with should_interrupt being queried between each entry to abort if needed, and on each write to out.

+
§Performance
+

Be sure that out is able to handle a lot of write calls. Otherwise wrap it in a BufWriter.

+
§Additional progress and fine-grained interrupt handling
+

For additional progress reporting, wrap out into a writer that counts throughput on each write. +This can also be used to react to interrupts on each write, instead of only for each entry.

pub fn is_dirty(&self) -> Result<bool, Error>

Available on crate feature status only.

Returns true if the repository is dirty. +This means it’s changed in one of the following ways:

+
    +
  • the index was changed in comparison to its working tree
    • +
  • the working tree was changed in comparison to the index
    • +
  • submodules are taken in consideration, along with their ignore and isActive configuration

pub fn tree_index_status<'repo, E>( + &'repo self, + tree_id: &oid, + worktree_index: &State, + pathspec: Option<&mut Pathspec<'repo>>, + renames: TrackRenames, + cb: impl FnMut(ChangeRef<'_, '_>, &State, &State) -> Result<Action, E>, +) -> Result<Outcome, Error>
where + E: Into<Box<dyn Error + Send + Sync>>,

Available on crate feature status only.

Produce the git status portion that shows the difference between tree_id (usually HEAD^{tree}) and the worktree_index +(typically the current .git/index), and pass all changes to cb(change, tree_index, worktree_index) with +full access to both indices that contributed to the change.

+

(It’s notable that internally, the tree_id is converted into an index before diffing these). +Set pathspec to Some(_) to further reduce the set of files to check.

+
§Notes
+
    +
  • This is a low-level method - prefer the Repository::status() platform instead for access to various iterators +over the same information.
    • +
+
Source§

impl Repository

Status

+
Source

pub fn status<P>(&self, progress: P) -> Result<Platform<'_, P>, Error>
where + P: Progress + 'static,

Available on crate feature status only.

Obtain a platform for configuring iterators for traversing git repository status information.

+

By default, this is set to the fastest and most immediate way of obtaining a status, +which is most similar to

+

git status --ignored=no

+

which implies that submodule information is provided by default.

+

Note that status.showUntrackedFiles is respected, which leads to untracked files being +collapsed by default. If that needs to be controlled, +configure the directory walk explicitly or more implicitly.

+

Pass progress to receive progress information on file modifications on this repository. +Use progress::Discard to discard all progress information.

+
§Deviation
+

Whereas Git runs the index-modified check before the directory walk to set entries +as up-to-date to (potentially) safe some disk-access, we run both in parallel which +ultimately is much faster.

+    pub is_old_form: bool,
+    pub worktree_checkout: bool,
+    pub superproject_configuration: bool,

Available on crate feature attributes only.
Expand description

A summary of the state of all parts forming a submodule, which allows to answer various questions about it.

+

Note that expensive questions about its presence in the HEAD or the index are left to the caller.

+

Fields§

§repository_exists: bool

if the submodule repository has been cloned.

+
§is_old_form: bool

if the submodule repository is located directly in the worktree of the superproject.

+
§worktree_checkout: bool

if the worktree is checked out.

+
§superproject_configuration: bool

If submodule configuration was found in the superproject’s .git/config file. +Note that the presence of a single section is enough, independently of the actual values.

+

+    pub changes: Option<Vec<Item>>,
+}
Available on crate features status and attributes only.
Expand description

A simplified status of the Submodule.

+

As opposed to the similar-sounding State, it is more exhaustive and potentially expensive to compute, +particularly for submodules without changes.

+

It’s produced by Submodule::status().

+

Fields§

§state: State

The cheapest part of the status that is always performed, to learn if the repository is cloned +and if there is a worktree checkout.

+
§index_id: Option<ObjectId>

The commit at which the submodule is supposed to be according to the super-project’s index. +None means the computation wasn’t performed, or the submodule didn’t exist in the super-project’s index anymore.

+
§checked_out_head_id: Option<ObjectId>

The commit-id of the HEAD at which the submodule is currently checked out. +None if the computation wasn’t performed as it was skipped early, or if no repository was available or +if the HEAD could not be obtained or wasn’t born.

+
§changes: Option<Vec<Item>>

The set of changes obtained from running something akin to git status in the submodule working tree.

+

None if the computation wasn’t performed as the computation was skipped early, or if no working tree was +available or repository was available.

+

Return Some(true) if the submodule status could be determined sufficiently and +if there are changes that would render this submodule dirty.

+

Return Some(false) if the submodule status could be determined and it has no changes +at all.

+

Return None if the repository clone or the worktree are missing entirely, which would leave +it to the caller to determine if that’s considered dirty or not.

Struct Submodule

Source 
pub struct Submodule<'repo> { /* private fields */ }
Available on crate feature attributes only.
Expand description

A stand-in for the submodule of a particular name.

+

Implementations§

Source§

impl Submodule<'_>

Source

pub fn status(&self, ignore: Ignore, check_dirty: bool) -> Result<Status, Error>

Available on crate feature status only.

Return the status of the submodule.

+

Use ignore to control the portion of the submodule status to ignore. It can be obtained from +submodule configuration using the ignore() method. +If check_dirty is true, the computation will stop once the first in a ladder operations +ordered from cheap to expensive shows that the submodule is dirty. +Thus, submodules that are clean will still impose the complete set of computation, as given.

+
Source

pub fn status_opts( + &self, + ignore: Ignore, + check_dirty: bool, + adjust_options: &mut dyn for<'a> FnMut(Platform<'a, Discard>) -> Platform<'a, Discard>, +) -> Result<Status, Error>

Available on crate feature status only.

Return the status of the submodule, just like status, but allows to adjust options +for more control over how the status is performed.

+

If check_dirty is true, the computation will stop once the first in a ladder operations +ordered from cheap to expensive shows that the submodule is dirty. When checking for detailed +status information (i.e. untracked file, modifications, HEAD-index changes) only the first change +will be kept to stop as early as possible.

+

Use &mut std::convert::identity for adjust_options if no specific options are desired. +A reason to change them might be to enable sorting to enjoy deterministic order of changes.

+

The status allows to easily determine if a submodule has changes.

+
Source§

impl Submodule<'_>

Access

+
Source

pub fn name(&self) -> &BStr

Return the submodule’s name.

+
Source

pub fn path(&self) -> Result<Cow<'_, BStr>, Error>

+

For details, see gix_submodule::File::path().

+
Source

pub fn url(&self) -> Result<Url, Error>

Return the url from which to clone or update the submodule.

+

This method takes into consideration submodule configuration overrides.

+
Source

pub fn update(&self) -> Result<Option<Update>, Error>

Return the update field from this submodule’s configuration, if present, or None.

+

This method takes into consideration submodule configuration overrides.

+
Source

pub fn branch(&self) -> Result<Option<Branch>, Error>

Return the branch field from this submodule’s configuration, if present, or None.

+

This method takes into consideration submodule configuration overrides.

+
Source

pub fn fetch_recurse(&self) -> Result<Option<FetchRecurse>, Error>

Return the fetchRecurseSubmodules field from this submodule’s configuration, or retrieve the value from fetch.recurseSubmodules if unset.

+
Source

pub fn ignore(&self) -> Result<Option<Ignore>, Error>

Return the ignore field from this submodule’s configuration, if present, or None.

+

This method takes into consideration submodule configuration overrides.

+
Source

pub fn shallow(&self) -> Result<Option<bool>, Error>

Return the shallow field from this submodule’s configuration, if present, or None.

+

If true, the submodule will be checked out with depth = 1. If unset, false is assumed.

+
Source

pub fn is_active(&self) -> Result<bool, Error>

Returns true if this submodule is considered active and can thus participate in an operation.

+

Please see the plumbing crate documentation for details.

+
Source

pub fn index_id(&self) -> Result<Option<ObjectId>, Error>

Return the object id of the submodule as stored in the index of the superproject, +or None if it was deleted from the index.

+

If None, but Some() when calling Self::head_id(), then the submodule was just deleted but the change +wasn’t yet committed. Note that None is also returned if the entry at the submodule path isn’t a submodule. +If Some(), but None when calling Self::head_id(), then the submodule was just added without having committed the change.

+
Source

pub fn head_id(&self) -> Result<Option<ObjectId>, Error>

Return the object id of the submodule as stored in HEAD^{tree} of the superproject, or None if it wasn’t yet committed.

+

If Some(), but None when calling Self::index_id(), then the submodule was just deleted but the change +wasn’t yet committed. Note that None is also returned if the entry at the submodule path isn’t a submodule. +If None, but Some() when calling Self::index_id(), then the submodule was just added without having committed the change.

+
Source

pub fn git_dir(&self) -> PathBuf

Return the path at which the repository of the submodule should be located.

+

The directory might not exist yet.

+
Source

pub fn work_dir(&self) -> Result<PathBuf, Error>

Return the path to the location at which the workdir would be checked out.

+

Note that it may be a path relative to the repository if, for some reason, the parent directory +doesn’t have a working dir set.

+
Source

pub fn git_dir_try_old_form(&self) -> Result<PathBuf, Error>

Return the path at which the repository of the submodule should be located, or the path inside of +the superproject’s worktree where it actually is located if the submodule in the ‘old-form’, thus is a directory +inside of the superproject’s work-tree.

+

Note that ‘old-form’ paths returned aren’t verified, i.e. the .git repository might be corrupt or otherwise +invalid - it’s left to the caller to try to open it.

+

Also note that the returned path may not actually exist.

+
Source

pub fn state(&self) -> Result<State, Error>

Query various parts of the submodule and assemble it into state information.

+
Source

pub fn open(&self) -> Result<Option<Repository>, Error>

Open the submodule as repository, or None if the submodule wasn’t initialized yet.

+

More states can be derived here:

+
    +
  • initialized - a repository exists, i.e. Some(repo) and the working tree is present.
    • +
  • uninitialized - a repository does not exist, i.e. None
    • +
  • deinitialized - a repository does exist, i.e. Some(repo), but its working tree is empty.
    • +
+

Also see the state() method for learning about the submodule. +The repository can also be used to learn about the submodule HEAD, i.e. where its working tree is at, +which may differ compared to the superproject’s index or HEAD commit.

Gradual Implementation +- Implement one method at a time +- Keep git2 fallback during transition period +- Comprehensive testing before removing fallbacks + +### 2. Error Handling +- Detailed error messages for debugging +- Proper error context preservation +- Graceful degradation where possible + +### 3. Compatibility +- Maintain existing API contracts +- Ensure no breaking changes to public interfaces +- Preserve existing behavior and semantics + +## Expected Outcomes + +### 1. Performance Improvements +- Faster operations due to pure Rust implementation +- Reduced memory allocations +- Better parallelization opportunities + +### 2. Code Quality +- Elimination of disingenuous comments +- More maintainable and honest codebase +- Better type safety and error handling + +### 3. Future-Proofing +- Alignment with modern Rust Git ecosystem +- Reduced dependency on C libraries +- Better integration with Rust tooling + +## Conclusion + +This refactoring plan demonstrates that the claims about Gix API complexity are indeed disingenuous. The Gitoxide project provides comprehensive, well-designed APIs that can handle all the operations currently falling back to git2. The proposed implementations are type-safe, performant, and integrate seamlessly with the existing submod type system. + +The refactoring will result in a more honest, maintainable, and performant codebase while eliminating the false claims about API stability and complexity. diff --git a/hk.pkl b/hk.pkl index 5169eed..6c24675 100644 --- a/hk.pkl +++ b/hk.pkl @@ -1,3 +1,9 @@ +/* + * SPDX-FileCopyrightText: 2025 Adam Poulemanos <89049923+bashandbone@users.noreply.github.com> + * + * * Licensed under the [Plain MIT License](LICENSE.md) +*/ + amends "package://github.com/jdx/hk/releases/download/v1.2.0/hk@1.2.0#/Config.pkl" import "package://github.com/jdx/hk/releases/download/v1.2.0/hk@1.2.0#/Builtins.pkl" @@ -48,8 +54,6 @@ local ci = (linters) { } } - - hooks { ["pre-commit"] { fix = true // automatically modify files with available linter fixes diff --git a/hk.pkl.license b/hk.pkl.license new file mode 100644 index 0000000..e590b97 --- /dev/null +++ b/hk.pkl.license @@ -0,0 +1,3 @@ +SPDX-FileCopyrightText: 2025 Adam Poulemanos <89049923+bashandbone@users.noreply.github.com> + +SPDX-License-Identifier: LicenseRef-PlainMIT OR MIT diff --git a/mise.toml b/mise.toml index 8d8753b..d7fcff4 100644 --- a/mise.toml +++ b/mise.toml @@ -1,18 +1,25 @@ +# SPDX-FileCopyrightText: 2025 Adam Poulemanos <89049923+bashandbone@users.noreply.github.com> +# +# SPDX-License-Identifier: LicenseRef-PlainMIT OR MIT + [tools] act = "latest" -bun = "latest" # We use bun to run mcp tool development servers.
