Patrick Steinhardt 9994cd3f 2018-06-25T11:56:52 treewide: remove use of C++ style comments C++ style comment ("//") are not specified by the ISO C90 standard and thus do not conform to it. While libgit2 aims to conform to C90, we did not enforce it until now, which is why quite a lot of these non-conforming comments have snuck into our codebase. Do a tree-wide conversion of all C++ style comments to the supported C style comments to allow us enforcing strict C90 compliance in a later commit.
Edward Thomson bfa1f022 2018-06-22T19:17:08 settings: optional unsaved index safety Add the `GIT_OPT_ENABLE_UNSAVED_INDEX_SAFETY` option, which will cause commands that reload the on-disk index to fail if the current `git_index` has changed that have not been saved. This will prevent users from - for example - adding a file to the index then calling a function like `git_checkout` and having that file be silently removed from the index since it was re-read from disk. Now calls that would re-read the index will fail if the index is "dirty", meaning changes have been made to it but have not been written. Users can either `git_index_read` to discard those changes explicitly, or `git_index_write` to write them.
Edward Thomson 787768c2 2018-06-22T19:07:54 index: return a unique error code on dirty index When the index is dirty, return GIT_EINDEXDIRTY so that consumers can identify the exact problem programatically.
Edward Thomson b242cdbf 2017-11-17T00:19:07 index: commit the changes to the index properly Now that the index has a "dirty" state, where it has changes that have not yet been committed or rolled back, our tests need to be adapted to actually commit or rollback the changes instead of assuming that the index can be operated on in its indeterminate state.
Edward Thomson dc4a18c7 2017-11-12T08:23:13 index: test dirty index bit Test that any changes to the index will mark the index as dirty. Also ensure that when we initialize a new index, read the index contents from disk, or write the index contents to disk that we reset the dirty flag to zero. Further ensure that an unforced read with dirty contents (when the on-disk index has not changed) does _not_ reset the dirty flag as we have not updated the contents of our index and our unsaved contents remain intact.
Edward Thomson 7330ae67 2018-06-26T10:45:57 index::addall tests: write the index When running `git_index_add_all`, we should write the index to disk so that we can re-read it safely during status.
Edward Thomson 08ea0d7d 2018-02-18T11:49:08 index::reuc tests: test that checkout succeeds The index::reuc tests must test that the checkout itself succeeds, otherwise subsequent tests are not valid. In fact, the checkouts were failing because when checking out `SAFE`, they cannot update the files that are in conflict. Change the checkout level to `FORCE` to ensure that they get updated correctly.
Edward Thomson c4ce017f 2018-02-18T22:27:34 index::names tests: add conflicts with high stages We add entries into the main index to correspond with the NAME entries that we're going to test. NAME entries store the results of conflicts occuring with rename detection during merge, and they must correspond to conflicts in the index. This test was mistakenly adding regular entries. The checkout validation failed, since it requires NAME entries to correspond to high-stage (conflict) entries. Correct the test to actually create conflicts.
Patrick Steinhardt ecf4f33a 2018-02-08T11:14:48 Convert usage of `git_buf_free` to new `git_buf_dispose`
Patrick Steinhardt cabe16df 2018-02-19T10:18:59 tests: index::filemodes: fix use of uninitialized memory The new index entry structure was not being initialized to all-zeroes. As that structure is used to add a new entry to the current index, and the hashing algorithm of the index making use of the uninitialized flags to calculate the state, we might miscompute the hash of the entry and add it at the wrong position. Later lookups would then fail. Initialize the structure with `memset` to fix the test breaking on some platforms.
Edward Thomson 5f774dbf 2018-02-11T10:14:13 git_index_add_frombuffer: only accept files/links Ensure that the buffer given to `git_index_add_frombuffer` represents a regular blob, an executable blob, or a link. Explicitly reject commit entries (submodules) - it makes little sense to allow users to add a submodule from a string; there's no possible path to success.
Patrick Steinhardt 6ee7d37a 2017-05-10T12:51:06 tests: index::tests: create sandboxed repo for locking The test `index::tests::can_lock_index` operates on the "testrepo.git" repository located inside of our source tree. While this is okay for tests which do read-only operations on these resouces, this specific test tries to lock the index by creating a lock. This will obviously fail on out-of-tree builds with read-only source trees. Fix the issue by creating a sandbox first.
Patrick Steinhardt 92d3ea4e 2017-05-19T13:04:32 tests: index::version: improve write test for index v4 The current write test does not trigger some edge-cases in the index version 4 path compression code. Rewrite the test to start off the an empty standard repository, creating index entries with interesting paths itself. This allows for more fine-grained control over checked paths. Furthermore, we now also verify that entry paths are actually reconstructed correctly.
Patrick Steinhardt 8fe33538 2017-05-19T12:45:48 tests: index::version: verify we write compressed index entries While we do have a test which checks whether a written index of version 4 has the correct version set, we do not check whether this actually enables path compression for index entries. This commit adds a new test by adding a number of index entries with equal path prefixes to the index and subsequently flushing that to disk. With suffix compression enabled by index version 4, only the last few bytes of these paths will actually have to be written to the index, saving a lot of disk space. For the test, differences are about an order of magnitude, allowing us to easily verify without taking a deeper look at actual on-disk contents.
Patrick Steinhardt 82368b1b 2017-05-12T10:04:42 tests: index::version: add test to read index version v4 While we have a simple test to determine whether we can write an index of version 4, we never verified that we are able to read this kind of index (and in fact, we were not able to do so). Add a new repository which has an index of version 4. This repository is then read from a new test.
Patrick Steinhardt fea0c81e 2017-05-12T09:09:07 tests: index::version: move up cleanup function The init and cleanup functions for test suites are usually prepended to our actual tests. The index::version test suite does not adhere to this stile. Fix this.
Patrick Steinhardt 86e88534 2016-08-29T13:09:58 tests: index: do not re-allocate index Plug a memory leak caused by re-allocating a `git_index` structure which has already been allocated by the test suite's initializer.
David Turner 5625d86b 2016-05-17T15:40:32 index: support index v4 Support reading and writing index v4. Index v4 uses a very simple compression scheme for pathnames, but is otherwise similar to index v3. Signed-off-by: David Turner <dturner@twitter.com>

Edward Thomson 6249d960 2016-06-29T17:55:44 index: include conflicts in `git_index_read_index` Ensure that we include conflicts when calling `git_index_read_index`, which will remove conflicts in the index that do not exist in the new target, and will add conflicts from the new target.
Edward Thomson 91fbf9d8 2016-06-01T22:31:16 test: ensure we can round-trip a written tree Read a tree into an index, write the index, then re-open the index and ensure that we are treesame to the original.
Edward Thomson 5baa20b8 2016-06-01T14:52:25 round-trip trees through index_read_index Read a tree into an index using `git_index_read_index` (by reading a tree into a new index, then reading that index into the current index), then write the index back out, ensuring that our new index is treesame to the tree that we read.
Patrick Steinhardt e756877d 2016-03-11T09:07:29 tests: nsec: correctly free nsec_path git_buf_clear does not free allocated memory associated with a git_buf. Use `git_buf_free` instead to correctly free its memory and plug the memory leak.
Edward Thomson 53fb823b 2016-03-07T17:37:17 index::racy: force racy entry Instead of hoping that we can get a racy entry by going real fast and praying real hard, just create a racy entry.
Edward Thomson 565c4199 2016-03-07T17:04:32 index::nsec: don't expect shit filesystems to not suck If the underlying filesystem doesn't support better than one second resolution, then don't expect that turning on `GIT_USE_NSEC` does anything magical to change that.

Edward Thomson 4afe536b 2016-02-28T16:02:49 tests: use legitimate object ids Use legitimate (existing) object IDs in tests so that we have the ability to turn on strict object validation when running tests.
Edward Thomson 6ddf533a 2016-02-23T18:29:16 git_index_add: validate objects in index entries (optionally) When `GIT_OPT_ENABLE_STRICT_OBJECT_CREATION` is turned on, validate the index entries given to `git_index_add`.
Edward Thomson a4c55069 2016-02-25T11:31:18 nsec: update staging test for GIT_USE_NSECS The index::nsec::staging_maintains_other_nanos test was created to ensure that when we stage an entry when GIT_USE_NSECS is *unset* that we truncate the index entry and do not persist the (old, invalid) nanosec values. Ensure that when GIT_USE_NSECS is *set* that we do not do that, and actually write the correct nanosecond values.
Edward Thomson 35439f59 2016-02-11T12:24:21 win32: introduce p_timeval that isn't stupid Windows defines `timeval` with `long`, which we cannot sanely cope with. Instead, use a custom timeval struct.

Edward Thomson 5f32c506 2015-11-16T18:06:52 racy: make git_index_read_index handle raciness Ensure that `git_index_read_index` clears the uptodate bit on files that it modifies. Further, do not propagate the cache from an on-disk index into another on-disk index. Although this should not be done, as `git_index_read_index` is used to bring an in-memory index into another index (that may or may not be on-disk), ensure that we do not accidentally bring in these bits when misused.
Edward Thomson c30051f0 2015-11-16T18:05:46 racy: ensure git_index_read_tree clears uptodate Ensure that `git_index_read_tree` clears the uptodate bit on files that it modifies.
Edward Thomson 956f4da8 2015-11-13T16:30:39 index: test for smudged entries on write only Test that entries are only smudged when we write the index: the entry smudging is to prevent us from updating an index in a way that it would be impossible to tell that an item was racy. Consider when we load an index: any entries that have the same (or newer) timestamp than the index itself are considered racy, and are subject to further scrutiny. If we *save* that index with the same entries that we loaded, then the index would now have a newer timestamp than the entries, and they would no longer be given that additional scrutiny, failing our racy detection! So test that we smudge those entries only on writing the new index, but that we can detect them (in diff) without having to write.
Edward Thomson d1101263 2015-11-13T15:32:48 index: don't detect raciness in uptodate entries Keep track of entries that we believe are up-to-date, because we added the index entries since the index was loaded. This prevents us from unnecessarily examining files that we wrote during the cleanup of racy entries (when we smudge racily clean files that have a timestamp newer than or equal to the index's timestamp when we read it). Without keeping track of this, we would examine every file that we just checked out for raciness, since all their timestamps would be newer than the index's timestamp.

Edward Thomson 6cc5023b 2015-11-03T11:27:31 index: test that add_bypath preserves symlinks Test that on platforms without `core.symlinks`, we preserve symlinks in `git_index_add_bypath`. (Users should correct the actual index entry's mode to change a link to a regular file.)
Edward Thomson 99a09f7f 2015-10-22T09:29:40 index: test that we round-trip nsecs Test that nanoseconds are round-tripped correctly when we read an index file that contains them. We should, however, ignore them because we don't understand them, and any new entries in the index should contain a `0` nsecs field, while existing preserving entries.
Axel Rasmussen c7b17fb5 2015-10-01T18:01:32 Merge branch 'master' into nsec_fix_next
Edward Thomson 21515f22 2015-09-29T15:49:16 index: also try conflict mode when inserting When we do not trust the on-disk mode, we use the mode of an existing index entry. This allows us to preserve executable bits on platforms that do not honor them on the filesystem. If there is no stage 0 index entry, also look at conflicts to attempt to answer this question: prefer the data from the 'ours' side, then the 'theirs' side before falling back to the common ancestor.
Edward Thomson 10df661b 2015-09-29T14:16:51 index: test that add_bypath preserves mode

Axel Rasmussen 0226f7dd 2015-08-29T13:59:20 diff/index: respect USE_NSEC for racily clean file detection
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.

Edward Thomson a32bc85e 2015-08-07T12:43:49 git_index_add: allow case changing renames On case insensitive platforms, allow `git_index_add` to provide a new path for an existing index entry. Previously, we would maintain the case in an index entry without the ability to change it (except by removing an entry and re-adding it.) Higher-level functions (like `git_index_add_bypath` and `git_index_add_frombuffers`) continue to keep the old path for easier usage.
Edward Thomson 280adb3f 2015-08-04T16:51:00 index: canonicalize directory case when adding On case insensitive systems, when given a user-provided path in the higher-level index addition functions (eg `git_index_add_bypath` / `git_index_add_frombuffer`), examine the index to try to match the given path to an existing directory. Various mechanisms can cause the on-disk representation of a folder to not match the representation in HEAD or the index - for example, a case changing rename of some file `a/file.txt` to `A/file.txt` will update the paths in the index, but not rename the folder on disk. If a user subsequently adds `a/other.txt`, then this should be stored in the index as `A/other.txt`.

Edward Thomson bdec3363 2015-08-03T17:48:33 win32: ensure hidden files can be staged
Carlos Martín Nieto b426ac90 2015-08-01T19:52:25 index: test that an unregistered submodule gets staged When we pass the path of a repository to `_bypath()`, we should behave like git and stage it as a `_COMMIT` regardless of whether it is registered a a submodule.

Carlos Martín Nieto 247d27c2 2015-07-11T19:41:03 index: allow add_bypath to update submodules Similarly to how git itself does it, allow the index update operation to stage a change in a submodule's HEAD.
Carlos Martín Nieto 0d98af09 2015-07-11T19:03:38 blob: fail to create a blob from a dir with EDIRECTORY This also affects `git_index_add_bypath()` by providing a better error message and a specific error code when a directory is passed.

Carlos Martín Nieto 6e611f7c 2015-06-22T14:17:39 index: add a diff test for smudging a file which becomes empty Even though the file is empty and thus the size in the entry matches, we should be able to detect it as a difference.
Carlos Martín Nieto 27133caf 2015-06-20T17:20:07 tests: move racy tests to the index They fit there much better, even though we often check by diffing, it's about the behaviour of the index.
Carlos Martín Nieto 46c84c72 2015-06-19T21:56:42 index: user a better assertion when comparing sizes This will tell us which numbers we were trying to compare, rather than just telling us that they're different.

Edward Thomson 666ae188 2015-05-19T17:52:13 git_index_add_all: test that conflicts are handled When confronted with a conflict in the index, `git_index_add_all` should stage the working directory copy. If there is no file in the working directory, the conflict should simply be removed.
Edward Thomson 9f545b9d 2015-05-19T11:23:59 introduce `git_index_entry_is_conflict` It's not always obvious the mapping between stage level and conflict-ness. More importantly, this can lead otherwise sane people to write constructs like `if (!git_index_entry_stage(entry))`, which (while technically correct) is unreadable. Provide a nice method to help avoid such messy thinking.

John Fultz d3282680 2015-04-20T23:41:04 Fix index-adding functions to know when to trust filemodes. The idea...sometimes, a filemode is user-specified via an explicit git_index_entry. In this case, believe the user, always. Sometimes, it is instead built up by statting the file system. In those cases, go with the existing logic we have to determine whether the file system supports all filemodes and symlinks, and make the best guess. On file systems which have full filemode and symlink support, this commit should make no difference. On others (most notably Windows), this will fix problems things like: * git_index_add and git_index_add_frombuffer() should be believed. * As a consequence, git_checkout_tree should make the filemodes in the index match the ones in the tree. * And diffs with GIT_DIFF_UPDATE_INDEX don't write the wrong filemodes. * And merges, and probably other downstream stuff now fixed, too. This makes my previous changes to checkout.c unnecessary, so they are now reverted. Also, added a test for index_entry permissions from git_index_add and git_index_add_frombuffer, both of which failed before these changes.

Carlos Martín Nieto 23a17803 2015-01-07T14:16:50 reset: remove reflog message override This function is meant to simulate what git does in the reset command, so we should include the reflog message in that.
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.
Damien PROFETA a275fbc0 2015-02-05T11:40:16 Add API to add a memory buffer to an index git_index_add_frombuffer enables now to store a memory buffer in the odb and to store an entry in the index directly if the index is attached to a repository.

Carlos Martín Nieto bb0757d5 2014-10-22T21:09:31 tree-cache: correct the entry_count calculation The entry_count field is the amount of index entries covered by a particular cache entry, that is how many files are there (recursively) under a particular directory. The current code that attemps to do this is severely defincient and is trying to count the amount of children, which always comes up to zero. We don't even need to recount, since we have the information during the cache creation. We can take that number and keep it, as we only ever invalidate or replace.
Carlos Martín Nieto 795d8e93 2014-09-29T08:03:22 index: make sure to write cached subtrees if parent is invalidated If e.g. the root tree is invalidated, we still want to write out its children, since those may still have valid cache entries.
Carlos Martín Nieto c2f8b215 2014-09-28T07:00:49 index: write out the tree cache extension Keeping the cache around after read-tree is only one part of the optimisation opportunities. In order to share the cache between program instances, we need to write the TREE extension to the index. Do so, taking the opportunity to rename 'entries' to 'entry_count' to match the name given in the format description. The included test is rather trivial, but works as a sanity check.
Carlos Martín Nieto ee4db1c1 2014-07-11T11:48:51 index: add tests for the tree cache These test that we invalidate at the right levels and that we remove the tree cache when clearing the index.
