Rework checkout internals (again)
I've tried to map out the detailed behaviors of checkout and make sure that we're handling the various cases correctly, along with providing options to allow us to emulate "git checkout" and "git checkout-index" with the various flags. I've thrown away flags in the checkout API that seemed like clutter and added some new ones. Also, I've converted the conflict callback to a general notification callback so we can emulate "git checkout" output and display "dirty" files. As of this commit, the new behavior is not working 100% but some of that is probably baked into tests that are not testing the right thing. This is a decent snapshot point, I think, along the way to getting the update done.

/**
|
||||
* Checkout behavior flags
|
||||
*
|
||||
* These flags control what checkout does with files. Pass in a
|
||||
* combination of these values OR'ed together. If you just pass zero
|
||||
* (i.e. no flags), then you are effectively doing a "dry run" where no
|
||||
* files will be modified.
|
||||
* In libgit2, the function of checkout is to update the working directory
|
||||
* to match a target tree given an expected baseline tree. It does not move
|
||||
* the HEAD commit - you do that separately. Typically the expected tree is
|
||||
* the (to-be-moved) HEAD commit.
|
||||
*
|
||||
* Checkout groups the working directory content into 3 classes of files:
|
||||
* (1) files that don't need a change, and files that do need a change
|
||||
* that either (2) we are allowed to modifed or (3) we are not. The flags
|
||||
* you pass in will decide which files we are allowed to modify.
|
||||
* Checkout examines the differences between the target and expected trees
|
||||
* plus the current working directory and groups files into five categories:
|
||||
*
|
||||
* By default, checkout is not allowed to modify any files. Anything
|
||||
* needing a change would be considered a conflict.
|
||||
*
|
||||
* GIT_CHECKOUT_UPDATE_UNMODIFIED means that checkout is allowed to update
|
||||
* any file where the working directory content matches the HEAD
|
||||
* (e.g. either the files match or the file is absent in both places).
|
||||
*
|
||||
* GIT_CHECKOUT_UPDATE_MISSING means checkout can create a missing file
|
||||
* that exists in the index and does not exist in the working directory.
|
||||
* This is usually desirable for initial checkout, etc. Technically, the
|
||||
* missing file differs from the HEAD, which is why this is separate.
|
||||
*
|
||||
* GIT_CHECKOUT_UPDATE_MODIFIED means checkout is allowed to update files
|
||||
* where the working directory does not match the HEAD so long as the file
|
||||
* actually exists in the HEAD. This option implies UPDATE_UNMODIFIED.
|
||||
*
|
||||
* GIT_CHECKOUT_UPDATE_UNTRACKED means checkout is allowed to update files
|
||||
* even if there is a working directory version that does not exist in the
|
||||
* HEAD (i.e. the file was independently created in the workdir). This
|
||||
* implies UPDATE_UNMODIFIED | UPDATE_MISSING (but *not* UPDATE_MODIFIED).
|
||||
* 1. UNMODIFIED - Files that match in all places.
|
||||
* 2. SAFE - Files where the working directory and the expect content match
|
||||
* that can be safely updated to the target.
|
||||
* 3. DIRTY/MISSING - Files where the working directory differs from the
|
||||
* expected content but there is no conflicting change with the target
|
||||
* tree. An example is a file that doesn't exist in the working
|
||||
* directory - no data would be lost as a result of writing this file.
|
||||
* The action to take with these files depends on the options you elect.
|
||||
* 4. CONFLICTS - Files where changes in the working directory conflicts
|
||||
* with changes to be applied by the target. If conflicts are found,
|
||||
* they prevent any other modifications from being made (although there
|
||||
* are options to override that and force the update, of course).
|
||||
* 5. UNTRACKED/IGNORED - Files in the working directory that are untracked
|
||||
* or ignored.
|
||||
*
|
||||
*
|
||||
* On top of these three basic strategies, there are some modifiers
|
||||
* options that can be applied:
|
||||
* You control the actions checkout takes with one of four base strategies:
|
||||
*
|
||||
* If any files need update but are disallowed by the strategy, normally
|
||||
* checkout calls the conflict callback (if given) and then aborts.
|
||||
* GIT_CHECKOUT_ALLOW_CONFLICTS means it is okay to update the files that
|
||||
* are allowed by the strategy even if there are conflicts. The conflict
|
||||
* callbacks are still made, but non-conflicting files will be updated.
|
||||
* - `GIT_CHECKOUT_NONE` is the default and applies no changes. It is a dry
|
||||
* run that you can use to find conflicts, etc. if you wish.
|
||||
*
|
||||
* Any unmerged entries in the index are automatically considered conflicts.
|
||||
* If you want to proceed anyhow and just skip unmerged entries, you can use
|
||||
* GIT_CHECKOUT_SKIP_UNMERGED which is less dangerous than just allowing all
|
||||
* conflicts. Alternatively, use GIT_CHECKOUT_USE_OURS to proceed and
|
||||
* checkout the stage 2 ("ours") version. GIT_CHECKOUT_USE_THEIRS means to
|
||||
* proceed and use the stage 3 ("theirs") version.
|
||||
* - `GIT_CHECKOUT_SAFE` is like `git checkout` and only applies changes
|
||||
* between the expected and target trees to files in category 2.
|
||||
*
|
||||
* GIT_CHECKOUT_UPDATE_ONLY means that update is not allowed to create new
|
||||
* files or delete old ones, only update existing content. With this
|
||||
* flag, files that needs to be created or deleted are not conflicts -
|
||||
* they are just skipped. This also skips typechanges to existing files
|
||||
* (because the old would have to be removed).
|
||||
* - `GIT_CHECKOUT_SAFE_CREATE` also creates files that are missing from the
|
||||
* working directory (category 3), even if there is no change between the
|
||||
* expected and target trees for those files. See notes below on
|
||||
* emulating `git checkout-index` for some of the subtleties of this.
|
||||
*
|
||||
* GIT_CHECKOUT_REMOVE_UNTRACKED means that files in the working directory
|
||||
* that are untracked (and not ignored) will be removed altogether. These
|
||||
* untracked files (that do not shadow index entries) are not considered
|
||||
* conflicts and would normally be ignored.
|
||||
* - `GIT_CHECKOUT_FORCE` is like `git checkout -f` and will update the
|
||||
* working directory to match the target content regardless of conflicts,
|
||||
* overwriting dirty and conflicting files.
|
||||
*
|
||||
*
|
||||
* There are some additional flags to modified the behavior of checkout:
|
||||
*
|
||||
* - GIT_CHECKOUT_ALLOW_CONFLICTS can be added to apply safe file updates
|
||||
* even if there are conflicts. Normally, the entire checkout will be
|
||||
* cancelled if any files are in category 4. With this flag, conflicts
|
||||
* will be skipped (though the notification callback will still be invoked
|
||||
* on the conflicting files if requested).
|
||||
*
|
||||
* - GIT_CHECKOUT_REMOVE_UNTRACKED means that files in the working directory
|
||||
* that are untracked (but not ignored) should be deleted. The are not
|
||||
* considered conflicts and would normally be ignored by checkout.
|
||||
*
|
||||
* - GIT_CHECKOUT_REMOVE_IGNORED means to remove ignored files from the
|
||||
* working directory as well. Obviously, these would normally be ignored.
|
||||
*
|
||||
* - GIT_CHECKOUT_UPDATE_ONLY means to only update the content of files that
|
||||
* already exist. Files will not be created nor deleted. This does not
|
||||
* make adds and deletes into conflicts - it just skips applying those
|
||||
* changes. This will also skip updates to typechanged files (since that
|
||||
* would involve deleting the old and creating the new).
|
||||
*
|
||||
* - Unmerged entries in the index are also considered conflicts. The
|
||||
* GIT_CHECKOUT_SKIP_UNMERGED flag causes us to skip files with unmerged
|
||||
* index entries. You can also use GIT_CHECKOUT_USE_OURS and
|
||||
* GIT_CHECKOUT_USE_THEIRS to proceeed with the checkout using either the
|
||||
* stage 2 ("ours") or stage 3 ("theirs") version of files in the index.
|
||||
*
|
||||
*
|
||||
* To emulate `git checkout`, use `GIT_CHECKOUT_SAFE` with a checkout
|
||||
* notification callback (see below) that displays information about dirty
|
||||
* files (i.e. files that don't need an update but that no longer match the
|
||||
* expected content). The default behavior will cancel on conflicts.
|
||||
*
|
||||
* To emulate `git checkout-index`, use `GIT_CHECKOUT_SAFE_CREATE` with a
|
||||
* notification callback that cancels the operation if a dirty-but-existing
|
||||
* file is found in the working directory. This core git command isn't
|
||||
* quite "force" but is sensitive about some types of changes.
|
||||
*
|
||||
* To emulate `git checkout -f`, you use `GIT_CHECKOUT_FORCE`.
|
||||
*
|
||||
*
|
||||
* Checkout is "semi-atomic" as in it will go through the work to be done
|
||||
* before making any changes and if may decide to abort if there are
|
||||
* conflicts, or you can use the conflict callback to explicitly abort the
|
||||
* action before any updates are made. Despite this, if a second process
|
||||
* is modifying the filesystem while checkout is running, it can't
|
||||
* conflicts, or you can use the notification callback to explicitly abort
|
||||
* the action before any updates are made. Despite this, if a second
|
||||
* process is modifying the filesystem while checkout is running, it can't
|
||||
* guarantee that the choices is makes while initially examining the
|
||||
* filesystem are still going to be correct as it applies them.

* content. Core git displays these files when checkout runs, but does

* - GIT_CHECKOUT_NOTIFY_UNTRACKED notifies for all untracked files that

* will be to GIT_STATUS_IGNORED.
