Patrick Steinhardt ded77bb1 2019-06-29T09:58:34 path: extract function to check whether a path supports symlinks When initializing a repository, we need to check whether its working directory supports symlinks to correctly set the initial value of the "core.symlinks" config variable. The code to check the filesystem is reusable in other parts of our codebase, like for example in our tests to determine whether certain tests can be expected to succeed or not. Extract the code into a new function `git_path_supports_symlinks` to avoid duplicate implementations. Remove a duplicate implementation in the repo test helper code.
Patrick Steinhardt e54343a4 2019-06-29T09:17:32 fileops: rename to "futils.h" to match function signatures Our file utils functions all have a "futils" prefix, e.g. `git_futils_touch`. One would thus naturally guess that their definitions and implementation would live in files "futils.h" and "futils.c", respectively, but in fact they live in "fileops.h". Rename the files to match expectations.
Edward Thomson 964c1c60 2019-07-20T11:02:30 Merge pull request #5176 from pks-t/pks/repo-template-head repository: do not initialize HEAD if it's provided by templates
Patrick Steinhardt 9d46f167 2019-07-19T10:50:51 repository: do not initialize HEAD if it's provided by templates When using templates to initialize a git repository, then git-init(1) will copy over all contents of the template directory. These will be preferred over the default ones created by git-init(1). While we mostly do the same, there is the exception of "HEAD". While we do copy over the template's HEAD file, afterwards we'll immediately re-initialize its contents with either the default "ref: refs/origin/master" or the init option's `initial_head` field. Let's fix the inconsistency with upstream git-init(1) by not overwriting the template HEAD, but only if the user hasn't set `opts.initial_head`. If the `initial_head` field has been supplied, we should use that indifferent from whether the template contained a HEAD file or not. Add tests to verify we correctly use the template directory's HEAD file and that `initial_head` overrides the template.
Patrick Steinhardt f3134a84 2019-07-19T10:41:10 repository: update error handling in `init_ext` Update `git_repository_init_ext` to use our typical style of error handling. The function had multiple statements which didn't `goto out` immediately but instead deferred it to later calls combined with `if` statements.
Patrick Steinhardt 869ae5a3 2019-07-19T10:15:43 repository: avoid swallowing error codes in `create_head` The error handling in `git_repository_create_head` completely swallows all error codes. While probably not too much of a problem, this also violates our usual coding style. Refactor the code to use a local `error` variable with the typical `goto out` statements.
Patrick Steinhardt 658022c4 2019-07-18T13:53:41 configuration: cvar -> configmap `cvar` is an unhelpful name. Refactor its usage to `configmap` for more clarity.
Etienne Samson 501c51b2 2019-06-26T14:49:50 repo: commondir resolution can sometimes fallback to the repodir For example, https://git-scm.com/docs/gitrepository-layout says: info Additional information about the repository is recorded in this directory. This directory is ignored if $GIT_COMMON_DIR is set and "$GIT_COMMON_DIR/info" will be used instead. So when looking for `info/attributes`, we need to check the commondir first, or fallback to "our" `info/attributes`.
Edward Thomson fc3a94ba 2019-05-20T07:13:42 repository: use size_t for length
Edward Thomson 0b5ba0d7 2019-06-06T16:36:23 Rename opt init functions to `options_init` In libgit2 nomenclature, when we need to verb a direct object, we name a function `git_directobject_verb`. Thus, if we need to init an options structure named `git_foo_options`, then the name of the function that does that should be `git_foo_options_init`. The previous names of `git_foo_init_options` is close - it _sounds_ as if it's initializing the options of a `foo`, but in fact `git_foo_options` is its own noun that should be respected. Deprecate the old names; they'll now call directly to the new ones.
Erik Aigner 9cc904da 2019-05-23T10:49:44 repository: fix garbage return value error was never initialized and a garbage value returned on success.
Edward Thomson 4069f924 2019-02-22T10:56:08 Merge pull request #4901 from pks-t/pks/uniform-map-api High-level map APIs
Patrick Steinhardt bbdcd450 2019-02-20T10:40:06 cache: fix misnaming of `git_cache_free` Functions that free a structure's contents but not the structure itself shall be named `dispose` in the libgit2 project, but the function `git_cache_free` does not follow this naming pattern. Fix this by renaming it to `git_cache_dispose` and adjusting all callers to make use of the new name.
Patrick Steinhardt 351eeff3 2019-01-23T10:42:46 maps: use uniform lifecycle management functions Currently, the lifecycle functions for maps (allocation, deallocation, resize) are not named in a uniform way and do not have a uniform function signature. Rename the functions to fix that, and stick to libgit2's naming scheme of saying `git_foo_new`. This results in the following new interface for allocation: - `int git_<t>map_new(git_<t>map **out)` to allocate a new map, returning an error code if we ran out of memory - `void git_<t>map_free(git_<t>map *map)` to free a map - `void git_<t>map_clear(git<t>map *map)` to remove all entries from a map This commit also fixes all existing callers.
Patrick Steinhardt efb20825 2019-02-14T13:05:49 branches: introduce flag to skip enumeration of certain HEADs Right now, the function `git_repository_foreach_head` will always iterate over all HEADs of the main repository and its worktrees. In some cases, it might be required to skip either of those, though. Add a flag in preparation for the following commit that enables this behaviour.
Edward Thomson f673e232 2018-12-27T13:47:34 git_error: use new names in internal APIs and usage Move to the `git_error` name in the internal API for error-related functions.

Edward Thomson 168fe39b 2018-11-28T14:26:57 object_type: use new enumeration names Use the new object_type enumeration names within the codebase.

Sven Strickroth f0714daf 2018-11-25T13:36:29 Fix warning C4133 incompatible types in MSVC Introduced in commit b433a22a979ae78c28c8b16f8c3487e2787cb73e. Signed-off-by: Sven Strickroth <email@cs-ware.de>
Edward Thomson 820e1e93 2018-10-20T02:17:22 repository: load_config for non-repo configs Teach `load_config` how to load all the configurations except (optionally) the repository configuration. This allows the new repository codepath to load the global/xdg/system configuration paths so that they can be inspected during repository initialization.
Edward Thomson b433a22a 2018-10-19T03:14:53 win32: emulate Git for Windows in symlink support Emulate the Git for Windows `core.symlinks` support. Since symbolic links are generally enabled for Administrator (and _may_ be enabled due to enabling Developer mode) but symbolic links are still sufficiently uncommon on Windows that Git users are expected to explicitly opt-in to symbolic links by enabling `core.symlinks=true` in a global (or xdg or system) configuration. When `core.symlinks=true` is set globally _and_ symbolic links support is detected then new repositories created will not have a `core.symlinks` set. If `core.symlinks` is _not_ set then no detection will be performed, and `core.symlinks=false` will be set in the repository configuration.
Etienne Samson 5c0c8fdd 2018-08-17T02:07:38 repository: assert that we're passed a valid head pointer
Patrick Steinhardt ecf4f33a 2018-02-08T11:14:48 Convert usage of `git_buf_free` to new `git_buf_dispose`
Etienne Samson c7964c22 2018-04-18T22:40:46 repository: being a worktree means we're not really bare We were previously conflating any error into GIT_ENOTFOUND, which might or might not be correct. This fixes the code so a config error is bubbled up, as well as preserving the semantics in the face of worktree-repositories
Patrick Steinhardt 585b5dac 2017-11-18T15:43:11 refcount: make refcounting conform to aliasing rules Strict aliasing rules dictate that for most data types, you are not allowed to cast them to another data type and then access the casted pointers. While this works just fine for most compilers, technically we end up in undefined behaviour when we hurt that rule. Our current refcounting code makes heavy use of casting and thus violates that rule. While we didn't have any problems with that code, Travis started spitting out a lot of warnings due to a change in their toolchain. In the refcounting case, the code is also easy to fix: as all refcounting-statements are actually macros, we can just access the `rc` field directly instead of casting. There are two outliers in our code where that doesn't work. Both the `git_diff` and `git_patch` structures have specializations for generated and parsed diffs/patches, which directly inherit from them. Because of that, the refcounting code is only part of the base structure and not of the children themselves. We can help that by instead passing their base into `GIT_REFCOUNT_INC`, though.
Patrick Steinhardt 529e873c 2017-05-23T11:51:00 config: pass repository when opening config files Our current configuration logic is completely oblivious of any repository, but only cares for actual file paths. Unfortunately, we are forced to break this assumption by the introduction of conditional includes, which are evaluated in the context of a repository. Right now, only one conditional exists with "gitdir:" -- it will only include the configuration if the current repository's git directory matches the value passed to "gitdir:". To support these conditionals, we have to break our API and make the repository available when opening a configuration file. This commit extends the `open` call of configuration backends to include another repository and adjusts existing code to have it available. This includes the user-visible functions `git_config_add_file_ondisk` and `git_config_add_backend`.
Patrick Steinhardt d02cf564 2017-05-23T12:56:41 repository: constify several repo parameters for getters Several functions to retrieve variables from a repository only return immutable values, which allows us to actually constify the passed-in repository parameter. Do so to help a later patch, which will only have access to a constant repository.
Patrick Steinhardt 0c7f49dd 2017-06-30T13:39:01 Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.
Ariel Davis af720bb6 2017-06-16T23:19:31 repository: remove trailing whitespace
Ariel Davis 9a46c777 2017-06-16T21:02:26 repository: do not initialize templates if dir is an empty string
Edward Thomson 2d486781 2017-06-12T12:02:27 repository: don't fail to create config option in inmemory repo When in an in-memory repository - without a configuration file - do not fail to create a configuration object.
Edward Thomson 9d49a43c 2017-06-12T12:01:10 repository_item_path: return ENOTFOUND when appropriate Disambiguate error values: return `GIT_ENOTFOUND` when the item cannot exist in the repository (perhaps because the repository is inmemory or otherwise not backed by a filesystem), return `-1` when there is a hard failure.
Edward Thomson fb3fc837 2017-06-12T11:45:09 repository_item_path: error messages lowercased
Patrick Steinhardt 6c23704d 2017-06-08T21:40:18 settings: rename `GIT_OPT_ENABLE_SYNCHRONOUS_OBJECT_CREATION` Initially, the setting has been solely used to enable the use of `fsync()` when creating objects. Since then, the use has been extended to also cover references and index files. As the option is not yet part of any release, we can still correct this by renaming the option to something more sensible, indicating not only correlation to objects. This commit renames the option to `GIT_OPT_ENABLE_FSYNC_GITDIR`. We also move the variable from the object to repository source code.

Carlos Martín Nieto e694e4e9 2017-05-20T14:17:36 Merge pull request #4174 from libgit2/ethomson/set_head_to_tag git_repository_set_head: use tag name in reflog
Patrick Steinhardt 2696c5c3 2017-05-19T09:21:17 repository: make check if repo is a worktree more strict To determine if a repository is a worktree or not, we currently check for the existence of a "gitdir" file inside of the repository's gitdir. While this is sufficient for non-broken repositories, we have at least one case of a subtly broken repository where there exists a gitdir file inside of a gitmodule. This will cause us to misidentify the submodule as a worktree. While this is not really a fault of ours, we can do better here by observing that a repository can only ever be a worktree iff its common directory and dotgit directory are different. This allows us to make our check whether a repo is a worktree or not more strict by doing a simple string comparison of these two directories. This will also allow us to do the right thing in the above case of a broken repository, as for submodules these directories will be the same. At the same time, this allows us to skip the `stat` check for the "gitdir" file for most repositories.
Patrick Steinhardt 9f9fd05f 2017-05-19T08:59:46 repository: factor out worktree check The check whether a repository is a worktree or not is currently done inside of `git_repository_open_ext`. As we want to extend this function later on, pull it out into its own function `repo_is_worktree` to ease working on it.
Patrick Steinhardt 32841973 2017-05-19T08:38:47 repository: improve parameter names for `find_repo` The out-parameters of `find_repo` containing found paths of a repository are a tad confusing, as they are not as obvious as they could be. Rename them like following to ease reading the code: - `repo_path` -> `gitdir_path` - `parent_path` -> `workdir_path` - `link_path` -> `gitlink_path` - `common_path` -> `commondir_path`
Patrick Steinhardt 57121a23 2017-05-19T08:34:32 repository: clear out-parameter instead of freeing it The `path` out-parameter of `find_repo` is being sanitized initially such that we do not try to append to existing content. The sanitization is done via `git_buf_free`, though, which forces us to needlessly reallocate the buffer later in the function. Fix this by using `git_buf_clear` instead.
Edward Thomson be343b88 2017-05-01T18:56:55 worktrees: cleanup some memory leaks Be sure to clean up looked up references. Free buffers instead of merely clearing them. Use `git__free` instead of `free`.
Patrick Steinhardt 74511aa2 2017-04-04T18:44:29 repository: add function to iterate over all HEADs While we already provide functions to get the current repository's HEAD, it is quite involved to iterate over HEADs of both the repository and all linked work trees. This commit implements a function `git_repository_foreach_head`, which accepts a callback which is then called for all HEAD files.
Patrick Steinhardt 3e84aa50 2017-04-05T13:47:09 repository: get worktree HEAD via `git_reference__read_head` The functions `git_repository_head_for_worktree` and `git_repository_detached_head_for_worktree` both implement their own logic to read the HEAD reference file. Use the new function `git_reference__read_head` instead to unify the code paths.
Patrick Steinhardt 987f5659 2017-04-04T17:12:22 repository: extract function to get path to a file in a work tree The function `read_worktree_head` has the logic embedded to construct the path to `HEAD` in the work tree's git directory, which is quite useful for other callers. Extract the logic into its own function to make it reusable by others.
Patrick Steinhardt 8242cc1a 2017-04-04T18:18:45 repository: set error message if trying to set HEAD to a checked out one If trying to set the HEAD of a repository to another reference, we have to check whether this reference is already checked out in another linked work tree. If it is, we will refuse setting the HEAD and return an error, but do not set a meaningful error message. Add one.
Edward Thomson e86d02f9 2017-04-03T00:10:47 git_repository_set_head: use remote name in reflog When `git_repository_set_head` is provided a remote reference, update the reflog with the tag name, like we do with a branch. This helps consumers match the semantics of `git checkout remote`.
Edward Thomson ea3bb5c0 2017-03-21T18:12:02 git_repository_set_head: use tag name in reflog When `git_repository_set_head` is provided a tag reference, update the reflog with the tag name, like we do with a branch. This helps consumers match the semantics of `git checkout tag`.

Patrick Steinhardt 39abd3ad 2016-11-04T13:39:54 worktree: compute workdir for worktrees opened via their gitdir When opening a worktree via the gitdir of its parent repository we fail to correctly set up the worktree's working directory. The problem here is two-fold: we first fail to see that the gitdir actually is a gitdir of a working tree and then subsequently fail to determine the working tree location from the gitdir. The first problem of not noticing a gitdir belongs to a worktree can be solved by checking for the existence of a `gitdir` file in the gitdir. This file points back to the gitlink file located in the working tree's working directory. As this file only exists for worktrees, it should be sufficient indication of the gitdir belonging to a worktree. The second problem, that is determining the location of the worktree's working directory, can then be solved by reading the `gitdir` file in the working directory's gitdir. When we now resolve relative paths and strip the final `.git` component, we have the actual worktree's working directory location.
Patrick Steinhardt 84f56cb0 2016-11-04T11:59:52 repository: rename `path_repository` and `path_gitlink` The `path_repository` variable is actually confusing to think about, as it is not always clear what the repository actually is. It may either be the path to the folder containing worktree and .git directory, the path to .git itself, a worktree or something entirely different. Actually, the intent of the variable is to hold the path to the gitdir, which is either the .git directory or the bare repository. Rename the variable to `gitdir` to avoid confusion. While at it, also rename `path_gitlink` to `gitlink` to improve consistency.
Patrick Steinhardt 384518d0 2015-10-27T14:17:52 repository: restrict checking out checked out branches If a branch is already checked out in a working tree we are not allowed to check out that branch in another repository. Introduce this restriction when setting a repository's HEAD.
Patrick Steinhardt 04fb12ab 2015-10-27T12:37:51 worktree: implement functions reading HEAD Implement `git_repository_head_for_worktree` and `git_repository_head_detached_for_worktree` for directly accessing a worktree's HEAD without opening it as a `git_repository` first.
Patrick Steinhardt 8c8d726e 2015-10-21T12:10:30 worktree: implement `git_repository_open_from_worktree` Add function `git_repository_open_from_worktree`, which allows to open a `git_worktree` as repository.
Patrick Steinhardt 854b5c70 2015-10-26T16:21:09 repository: expose `repo_init_create_head` Expose the function `repo_init_create_head` as `git_repository_create_head`.
Patrick Steinhardt 4292837d 2015-09-24T14:37:10 config: open configuration in commondir A repository's configuartion file can always be found in the GIT_COMMON_DIR, which has been newly introduced. For normal repositories this does change nothing, but for working trees this change allows to access the shared configuration file.
Patrick Steinhardt 79ab3ef6 2015-10-15T15:58:05 repository: introduce is_worktree variable
Patrick Steinhardt c5f3da96 2016-11-11T14:36:43 repository: use `git_repository_item_path` The recent introduction of the commondir variable of a repository requires callers to distinguish whether their files are part of the dot-git directory or the common directory shared between multpile worktrees. In order to take the burden from callers and unify knowledge on which files reside where, the `git_repository_item_path` function has been introduced which encapsulate this knowledge. Modify most existing callers of `git_repository_path` to use `git_repository_item_path` instead, thus making them implicitly aware of the common directory.
Patrick Steinhardt cb3269c9 2016-11-11T13:46:59 repository: add function to retrieve paths for repo items
Patrick Steinhardt c09fd54e 2015-09-16T12:10:11 repository: introduce commondir variable The commondir variable stores the path to the common directory. The common directory is used to store objects and references shared across multiple repositories. A current use case is the newly introduced `git worktree` feature, which sets up a separate working copy, where the backing git object store and references are pointed to by the common directory.
Brock Peabody 4d99c4cf 2016-11-23T18:32:48 Allow for caching of submodules. Added `git_repository_submodule_cache_all` to initialze a cache of submodules on the repository so that operations looking up N submodules are O(N) and not O(N^2). Added a `git_repository_submodule_cache_clear` function to remove the cache. Also optimized the function that loads all submodules as it was itself O(N^2) w.r.t the number of submodules, having to loop through the `.gitmodules` file once per submodule. I changed it to process the `.gitmodules` file once, into a map. Signed-off-by: David Turner <dturner@twosigma.com>
Edward Thomson 909d5494 2016-12-29T12:25:15 giterr_set: consistent error messages Error messages should be sentence fragments, and therefore: 1. Should not begin with a capital letter, 2. Should not conclude with punctuation, and 3. Should not end a sentence and begin a new one
Patrick Steinhardt 0f316096 2016-11-11T16:55:33 repository: do not interpret all files as gitlinks in discovery When trying to find a discovery, we walk up the directory structure checking if there is a ".git" file or directory and, if so, check its validity. But in the case that we've got a ".git" file, we do not want to unconditionally assume that the file is in fact a ".git" file and treat it as such, as we would error out if it is not. Fix the issue by only treating a file as a gitlink file if it ends with "/.git". This allows users of the function to discover a repository by handing in any path contained inside of a git repository.
Josh Triplett c9e967a1 2016-11-10T03:51:12 git_repository_open_ext: fix handling of $GIT_NAMESPACE The existing code would set a namespace of "" (empty string) with GIT_NAMESPACE unset. In a repository where refs/heads/namespaces/ exists, that can produce incorrect results. Detect that case and avoid setting the namespace at all. Since that makes the last assignment to error conditional, and the previous assignment can potentially get GIT_ENOTFOUND, set error to 0 explicitly to prevent the call from incorrectly failing with GIT_ENOTFOUND.
Edward Thomson b118f647 2016-07-22T14:02:00 repository: don't cast to `int` for no reason And give it a default so that some compilers don't (unnecessarily) complain.
Josh Triplett 2b490284 2016-06-24T15:59:37 find_repo: Clean up and simplify logic find_repo had a complex loop and heavily nested conditionals, making it difficult to follow. Simplify this as much as possible: - Separate assignments from conditionals. - Check the complex loop condition in the only place it can change. - Break out of the loop on error, rather than going through the rest of the loop body first. - Handle error cases by immediately breaking, rather than nesting conditionals. - Free repo_link unconditionally on the way out of the function, rather than in multiple places. - Add more comments on the remaining complex steps.
Josh Triplett 0dd98b69 2016-04-03T17:22:07 Add GIT_REPOSITORY_OPEN_FROM_ENV flag to respect $GIT_* environment vars git_repository_open_ext provides parameters for the start path, whether to search across filesystems, and what ceiling directories to stop at. git commands have standard environment variables and defaults for each of those, as well as various other parameters of the repository. To avoid duplicate environment variable handling in users of libgit2, add a GIT_REPOSITORY_OPEN_FROM_ENV flag, which makes git_repository_open_ext automatically handle the appropriate environment variables. Commands that intend to act just like those built into git itself can use this flag to get the expected default behavior. git_repository_open_ext with the GIT_REPOSITORY_OPEN_FROM_ENV flag respects $GIT_DIR, $GIT_DISCOVERY_ACROSS_FILESYSTEM, $GIT_CEILING_DIRECTORIES, $GIT_INDEX_FILE, $GIT_NAMESPACE, $GIT_OBJECT_DIRECTORY, and $GIT_ALTERNATE_OBJECT_DIRECTORIES. In the future, when libgit2 gets worktree support, git_repository_open_env will also respect $GIT_WORK_TREE and $GIT_COMMON_DIR; until then, git_repository_open_ext with this flag will error out if either $GIT_WORK_TREE or $GIT_COMMON_DIR is set.
Josh Triplett 39c6fca3 2016-04-03T16:01:01 Add GIT_REPOSITORY_OPEN_NO_DOTGIT flag to avoid appending /.git GIT_REPOSITORY_OPEN_NO_SEARCH does not search up through parent directories, but still tries the specified path both directly and with /.git appended. GIT_REPOSITORY_OPEN_BARE avoids appending /.git, but opens the repository in bare mode even if it has a working directory. To support the semantics git uses when given $GIT_DIR in the environment, provide a new GIT_REPOSITORY_OPEN_NO_DOTGIT flag to not try appending /.git.
Josh Triplett ed577134 2016-04-03T19:24:15 Fix repository discovery with ceiling_dirs at current directory git only checks ceiling directories when its search ascends to a parent directory. A ceiling directory matching the starting directory will not prevent git from finding a repository in the starting directory or a parent directory. libgit2 handled the former case correctly, but differed from git in the latter case: given a ceiling directory matching the starting directory, but no repository at the starting directory, libgit2 would stop the search at that point rather than finding a repository in a parent directory. Test case using git command-line tools: /tmp$ git init x Initialized empty Git repository in /tmp/x/.git/ /tmp$ cd x/ /tmp/x$ mkdir subdir /tmp/x$ cd subdir/ /tmp/x/subdir$ GIT_CEILING_DIRECTORIES=/tmp/x git rev-parse --git-dir fatal: Not a git repository (or any of the parent directories): .git /tmp/x/subdir$ GIT_CEILING_DIRECTORIES=/tmp/x/subdir git rev-parse --git-dir /tmp/x/.git Fix the testsuite to test this case (in one case fixing a test that depended on the current behavior), and then fix find_repo to handle this case correctly. In the process, simplify and document the logic in find_repo(): - Separate the concepts of "currently checking a .git directory" and "number of iterations left before going further counts as a search" into two separate variables, in_dot_git and min_iterations. - Move the logic to handle in_dot_git and append /.git to the top of the loop. - Only search ceiling_dirs and find ceiling_offset after running out of min_iterations; since ceiling_offset only tracks the longest matching ceiling directory, if ceiling_dirs contained both the current directory and a parent directory, this change makes find_repo stop the search at the parent directory.
Edward Thomson d5592378 2016-04-26T11:39:53 annotated_commit: provide refs and description Differentiate between the ref_name used to create an annotated_commit (that can subsequently be used to look up the reference) and the description that we resolved this with (which _cannot_ be looked up). The description is used for things like reflogs (and may be a ref name, and ID something that we revparsed to get here), while the ref name must actually be a reference name, and is used for things like rebase to return to the initial branch.

Edward Thomson 538dfc88 2015-09-17T18:12:05 repository: only reserve repo dirs in the workdir Check that the repository directory is beneath the workdir before adding it to the list of reserved paths. If it is not, then there is no possibility of checking out files into it, and it should not be a reserved word. This is a particular problem with submodules where the repo directory may be in the super's .git directory.
Edward Thomson ac2fba0e 2015-09-16T15:07:27 git_futils_mkdir_*: make a relative-to-base mkdir Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter assumes that we own everything beneath the base, as if it were being called with a base of the repository or working directory, and is tailored towards checkout and ensuring that there is no bogosity beneath the base that must be cleaned up. This is (at best) slow and (at worst) unsafe in the larger context of a filesystem where we do not own things and cannot do things like unlink symlinks that are in our way.

Carlos Martín Nieto 16c73d38 2015-06-23T20:44:27 repository: check the format version This is something we do on re-init but not when opening a repository. This hasn't particularly mattered up to now as the version has been 0 ever since the first release of git, but the times, they're a-changing and we will soon see version 1 in the wild. We need to make sure we don't open those.
Carlos Martín Nieto 99e11cdd 2015-06-23T20:43:49 repository: don't error out if there is no version git will assume the repository format version is 0 if the value is not there. Do the same.
Carlos Martín Nieto dfda2f68 2015-04-27T19:27:29 submodule: remove the per-repo cache Having this cache and giving them out goes against our multithreading guarantees and it makes it impossible to use submodules in a multi-threaded environment, as any thread can ask for a refresh which may reallocate some string in the submodule struct which we've accessed in a different one via a getter. This makes the submodules behave more like remotes, where each object is created upon request and not shared except explicitly by the user. This means that some tests won't pass yet, as they assume they can affect the submodule objects in the cache and that will affect later operations.

Carlos Martín Nieto 9a97f49e 2014-12-21T15:31:03 config: borrow refcounted references This changes the get_entry() method to return a refcounted version of the config entry, which you have to free when you're done. This allows us to avoid freeing the memory in which the entry is stored on a refresh, which may happen at any time for a live config. For this reason, get_string() has been forbidden on live configs and a new function get_string_buf() has been added, which stores the string in a git_buf which the user then owns. The functions which parse the string value takea advantage of the borrowing to parse safely and then release the entry.
Carlos Martín Nieto 4e498646 2015-01-15T16:50:31 repository: remove log message override for switching the active branch We want to use the "checkout: moving from ..." message in order to let git know when a change of branch has happened.

Carlos Martín Nieto 659cf202 2015-01-07T12:23:05 Remove the signature from ref-modifying functions The signature for the reflog is not something which changes dynamically. Almost all uses will be NULL, since we want for the repository's default identity to be used, making it noise. In order to allow for changing the identity, we instead provide git_repository_set_ident() and git_repository_ident() which allow a user to override the choice of signature.
