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.
658022c4	2019-07-18T13:53:41	configuration: cvar -> configmap `cvar` is an unhelpful name. Refactor its usage to `configmap` for more clarity.
6574cd00	2019-06-08T19:25:36	index: rename `frombuffer` to `from_buffer` The majority of functions are named `from_something` (with an underscore) instead of `fromsomething`. Update the index functions for consistency with the rest of the library.

0bf7e043	2019-01-24T12:12:04	index: preserve extension parsing errors Previously, we would clobber any extension-specific error message with an "extension is truncated" message. This makes `read_extension` correctly preserve those errors, takes responsibility for truncation errors, and adds a new message with the actual extension signature for unsupported mandatory extensions.

8b6e2895	2018-09-21T15:18:03	index: fix adding index entries with conflicting files When adding an index entry "a/b/c" while an index entry "a/b" already exists, git will happily remove "a/b/c" and only add the new index entry: $ git init test Initialized empty Git repository in /tmp/test.repo/test/.git/ $ touch x $ git add x $ rm x $ mkdir x $ touch x/y $ git add x/y $ git status A x/y The other way round, adding an index entry "a/b" with an entry "a/b/c" already existing is equivalent, where git will remove "a/b/c" and add "a/b". In contrast, libgit2 will currently fail to add these properly and instead complain about the entry appearing as both a file and a directory. This is a programming error, though: our current code already tries to detect and, in the case of `git_index_add`, to automatically replace such index entries. Funnily enough, we already remove the conflicting index entries, but instead of adding the new entry we then bail out afterwards. This leaves callers with the worst of both worlds: we both remove the old entry but fail to add the new one. The root cause is weird semantics of the `has_file_name` and `has_dir_name` functions. While these functions only sound like they are responsible for detecting such conflicts, they will also already remove them in case where its `ok_to_replace` parameter is set. But even if we tell it to replace such entries, it will return an error code. Fix the error by returning success in case where the entries have been replaced. Fix an already existing test which tested for wrong behaviour. Note that the test didn't notice that the resulting tree had no entries. Thus it is fine to change existing behaviour here, as the previous result could've let to silently loosing data. Also add a new test that verifies behaviour in the reverse conflicting case.
fbc0dcda	2018-10-08T13:01:23	index: add failing test for writing an invalid tree from an unowned index When the index does not belong to any repository, we do not do any checks of the target id going in as we cannot verify that it exists. When we then write it out to a repository as a tree, we fail to perform the object existance and type-matching check that we do in other code-paths. This leads to being able to write trees which point to non-existent blobs even with strict object creation enabled.
3a1f5df8	2018-08-24T09:15:29	tests: verify adding index conflicts with invalid filemodes fails Commit 581d5492f (Fix leak in index.c, 2018-08-16) was fixing a memory leak in our code adding conflicts to the index when the added index entries have an invalid file mode. The memory leak was previously undiscovered as there are no tests covering this scenario, which is now being added by this commit.
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.
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.
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.
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.
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.
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.
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.
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.

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.
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.
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.
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.
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.
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.
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.

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.

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.
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.
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.
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.

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.

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.

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.
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`.

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.

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.

index: fix adding index entries with conflicting files When adding an index entry "a/b/c" while an index entry "a/b" already exists, git will happily remove "a/b/c" and only add the new index entry: $ git init test Initialized empty Git repository in /tmp/test.repo/test/.git/ $ touch x $ git add x $ rm x $ mkdir x $ touch x/y $ git add x/y $ git status A x/y The other way round, adding an index entry "a/b" with an entry "a/b/c" already existing is equivalent, where git will remove "a/b/c" and add "a/b". In contrast, libgit2 will currently fail to add these properly and instead complain about the entry appearing as both a file and a directory. This is a programming error, though: our current code already tries to detect and, in the case of `git_index_add`, to automatically replace such index entries. Funnily enough, we already remove the conflicting index entries, but instead of adding the new entry we then bail out afterwards. This leaves callers with the worst of both worlds: we both remove the old entry but fail to add the new one. The root cause is weird semantics of the `has_file_name` and `has_dir_name` functions. While these functions only sound like they are responsible for detecting such conflicts, they will also already remove them in case where its `ok_to_replace` parameter is set. But even if we tell it to replace such entries, it will return an error code. Fix the error by returning success in case where the entries have been replaced. Fix an already existing test which tested for wrong behaviour. Note that the test didn't notice that the resulting tree had no entries. Thus it is fine to change existing behaviour here, as the previous result could've let to silently loosing data. Also add a new test that verifies behaviour in the reverse conflicting case.

index: add failing test for writing an invalid tree from an unowned index When the index does not belong to any repository, we do not do any checks of the target id going in as we cannot verify that it exists. When we then write it out to a repository as a tree, we fail to perform the object existance and type-matching check that we do in other code-paths. This leads to being able to write trees which point to non-existent blobs even with strict object creation enabled.

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.

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.

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.

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.

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.

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.

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`.

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.

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.

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.

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.

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.

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.

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.

conflicts: when adding conflicts, remove staged When adding a conflict for some path, remove the staged entry. Otherwise, an illegal index (with both stage 0 and high-stage entries) would result.

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.

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.
