c0487bde	2018-01-12T08:23:43	tree: reject writing null-OID entries to a tree In commit a96d3cc3f (cache-tree: reject entries with null sha1, 2017-04-21), the git.git project has changed its stance on null OIDs in tree objects. Previously, null OIDs were accepted in tree entries to help tools repair broken history. This resulted in some problems though in that many code paths mistakenly passed null OIDs to be added to a tree, which was not properly detected. Align our own code base according to the upstream change and reject writing tree entries early when the OID is all-zero.

35079f50	2017-04-21T07:31:56	odb: add option to turn off hash verification Verifying hashsums of objects we are reading from the ODB may be costly as we have to perform an additional hashsum calculation on the object. Especially when reading large objects, the penalty can be as high as 35%, as can be seen when executing the equivalent of `git cat-file` with and without verification enabled. To mitigate for this, we add a global option for libgit2 which enables the developer to turn off the verification, e.g. when he can be reasonably sure that the objects on disk won't be corrupted.
28a0741f	2017-04-10T09:30:08	odb: verify object hashes The upstream git.git project verifies objects when looking them up from disk. This avoids scenarios where objects have somehow become corrupt on disk, e.g. due to hardware failures or bit flips. While our mantra is usually to follow upstream behavior, we do not do so in this case, as we never check hashes of objects we have just read from disk. To fix this, we create a new error class `GIT_EMISMATCH` which denotes that we have looked up an object with a hashsum mismatch. `odb_read_1` will then, after having read the object from its backend, hash the object and compare the resulting hash to the expected hash. If hashes do not match, it will return an error. This obviously introduces another computation of checksums and could potentially impact performance. Note though that we usually perform I/O operations directly before doing this computation, and as such the actual overhead should be drowned out by I/O. Running our test suite seems to confirm this guess. On a Linux system with best-of-five timings, we had 21.592s with the check enabled and 21.590s with the ckeck disabled. Note though that our test suite mostly contains very small blobs only. It is expected that repositories with bigger blobs may notice an increased hit by this check. In addition to a new test, we also had to change the odb::backend::nonrefreshing test suite, which now triggers a hashsum mismatch when looking up the commit "deadbeef...". This is expected, as the fake backend allocated inside of the test will return an empty object for the OID "deadbeef...", which will obviously not hash back to "deadbeef..." again. We can simply adjust the hash to equal the hash of the empty object here to fix this test.
d59dabe5	2017-04-10T09:00:51	tests: object: test looking up corrupted objects We currently have no tests which check whether we fail reading corrupted objects. Add one which modifies contents of an object stored on disk and then tries to read the object.
86c03552	2017-04-10T09:27:04	tests: object: create sandbox The object::lookup tests do use the "testrepo.git" repository in a read-only way, so we do not set up the repository as a sandbox but simply open it. But in a future commit, we will want to test looking up objects which are corrupted in some way, which requires us to modify the on-disk data. Doing this in a repository without creating the sandbox will modify contents of our libgit2 repository, though. Create the repository in a sandbox to avoid this.
1d41b86c	2016-11-14T12:22:20	tree: add a failing test for unsorted input We do not currently use the sorted version of this input in the function, which means we produce bad results.

92249656	2016-05-19T15:21:26	tree: use testrepo2 for the tree updater tests This gives us trees with subdirectories, which the new test needs.
9464f9eb	2016-05-02T17:36:58	Introduce a function to create a tree based on a different one Instead of going through the usual steps of reading a tree recursively into an index, modifying it and writing it back out as a tree, introduce a function to perform simple updates more efficiently. `git_tree_create_updated` avoids reading trees which are not modified and supports upsert and delete operations. It is not as versatile as modifying the index, but it makes some common operations much more efficient.
eb39284b	2016-04-25T12:16:05	tag: ignore extra header fields While no extra header fields are defined for tags, git accepts them by ignoring them and continuing the search for the message. There are a few tags like this in the wild which git parses just fine, so we should do the same.
6669e3e8	2015-11-08T04:28:08	blob: remove _fromchunks() The callback mechanism makes it awkward to write data from an IO source; move to `_fromstream()` which lets the caller remain in control, in the same vein as we prefer iterators over foreach callbacks.
35e68606	2015-11-04T10:36:50	blob: fix fromchunks iteration counter By returning when the count goes to zero rather than below it, setting `howmany` to 7 in fact writes out the string 6 times. Correct the termination condition to write out the string the amount of times we specify.
0a5c6028	2015-11-04T10:30:48	blob: introduce creating a blob by writing into a stream The pair of `git_blob_create_frombuffer()` and `git_blob_create_frombuffer_commit()` is meant to replace `git_blob_create_fromchunks()` by providing a way for a user to write a new blob when they want filtering or they do not know the size. This approach allows the caller to retain control over when to add data to this buffer and a more natural fit into higher-level language's own stream abstractions instead of having to handle IO wait in the callback. The in-memory buffer size of 2MB is chosen somewhat arbitrarily to be a round multiple of usual page sizes and a value where most blobs seem likely to be either going to be way below or way over that size. It's also a round number of pages. This implementation re-uses the helper we have from `_fromchunks()` so we end up writing everything to disk, but hopefully more efficiently than with a default filebuf. A later optimisation can be to avoid writing the in-memory contents to disk, with some extra complexity.
60a194aa	2016-03-20T11:00:12	tree: re-use the id and filename in the odb object Instead of copying over the data into the individual entries, point to the originals, which are already in a format we can use.
ea5bf6bb	2016-03-04T12:34:38	treebuilder: don't try to verify submodules exist in the odb Submodules don't exist in the objectdb and the code is making us try to look for a blob with its commit id, which is obviously not going to work. Skip the test if the user wants to insert a submodule.

4d3f1f97	2014-06-09T04:38:22	treebuilder: use a map instead of vector to store the entries Finding a filename in a vector means we need to resort it every time we want to read from it, which includes every time we want to write to it as well, as we want to find duplicate keys. A hash-map fits what we want to do much more accurately, as we do not care about sorting, but just the particular filename. We still keep removed entries around, as the interface let you assume they were going to be around until the treebuilder is cleared or freed, but in this case that involves an append to a vector in the filter case, which can now fail. The only time we care about sorting is when we write out the tree, so let's make that the only time we do any sorting.

af567e88	2014-05-12T10:44:13	Merge pull request #2334 from libgit2/rb/fix-2333 Be more careful with user-supplied buffers
1e4976cb	2014-05-08T10:17:14	Be more careful with user-supplied buffers This adds in missing calls to `git_buf_sanitize` and fixes a number of places where `git_buf` APIs could inadvertently write NUL terminator bytes into invalid buffers. This also changes the behavior of `git_buf_sanitize` to NUL terminate a buffer if it can and of `git_buf_shorten` to do nothing if it can. Adds tests of filtering code with zeroed (i.e. unsanitized) buffer which was previously triggering a segfault.
5269008c	2014-05-06T16:01:49	Add filter options and ALLOW_UNSAFE Diff and status do not want core.safecrlf to actually raise an error regardless of the setting, so this extends the filter API with an additional options flags parameter and adds a flag so that filters can be applied with GIT_FILTER_OPT_ALLOW_UNSAFE, indicating that unsafe filter application should be downgraded from a failure to a warning.
217c029b	2014-04-09T14:08:22	commit: safer commit creation with reference update The current version of the commit creation and amend function are unsafe to use when passing the update_ref parameter, as they do not check that the reference at the moment of update points to what the user expects. Make sure that we're moving history forward when we ask the library to update the reference for us by checking that the first parent of the new commit is the current value of the reference. We also make sure that the ref we're updating hasn't moved between the read and the write. Similarly, when amending a commit, make sure that the current tip of the branch is the commit we're amending.
eb46fb2b	2014-03-08T00:49:18	Add failing test for git_object_short_id
13f7ecd7	2014-03-04T16:23:28	Add git_object_short_id API to get short id string This finds a short id string that will unambiguously select the given object, starting with the core.abbrev length (usually 7) and growing until it is no longer ambiguous.
80c29fe9	2014-01-17T10:45:11	Add git_commit_amend API This adds an API to amend an existing commit, basically a shorthand for creating a new commit filling in missing parameters from the values of an existing commit. As part of this, I also added a new "sys" API to create a commit using a callback to get the parents. This allowed me to rewrite all the other commit creation APIs so that temporary allocations are no longer needed.

452c7de6	2013-12-12T14:16:40	Add git_treebuilder_insert test and clarify doc This wasn't being tested and since it has a callback, I fixed it even though the return value of this callback is not treated like any of the other callbacks in the API.
19853bdd	2013-12-10T13:01:34	Update git_blob_create_fromchunks callback behavr The callback to supply data chunks could return a negative value to stop creation of the blob, but we were neither using GIT_EUSER nor propagating the return value. This makes things use the new behavior of returning the negative value back to the user.
25e0b157	2013-12-06T15:07:57	Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.

treebuilder: use a map instead of vector to store the entries Finding a filename in a vector means we need to resort it every time we want to read from it, which includes every time we want to write to it as well, as we want to find duplicate keys. A hash-map fits what we want to do much more accurately, as we do not care about sorting, but just the particular filename. We still keep removed entries around, as the interface let you assume they were going to be around until the treebuilder is cleared or freed, but in this case that involves an append to a vector in the filter case, which can now fail. The only time we care about sorting is when we write out the tree, so let's make that the only time we do any sorting.

Merge pull request #2334 from libgit2/rb/fix-2333 Be more careful with user-supplied buffers

Be more careful with user-supplied buffers This adds in missing calls to `git_buf_sanitize` and fixes a number of places where `git_buf` APIs could inadvertently write NUL terminator bytes into invalid buffers. This also changes the behavior of `git_buf_sanitize` to NUL terminate a buffer if it can and of `git_buf_shorten` to do nothing if it can. Adds tests of filtering code with zeroed (i.e. unsanitized) buffer which was previously triggering a segfault.

Add filter options and ALLOW_UNSAFE Diff and status do not want core.safecrlf to actually raise an error regardless of the setting, so this extends the filter API with an additional options flags parameter and adds a flag so that filters can be applied with GIT_FILTER_OPT_ALLOW_UNSAFE, indicating that unsafe filter application should be downgraded from a failure to a warning.

commit: safer commit creation with reference update The current version of the commit creation and amend function are unsafe to use when passing the update_ref parameter, as they do not check that the reference at the moment of update points to what the user expects. Make sure that we're moving history forward when we ask the library to update the reference for us by checking that the first parent of the new commit is the current value of the reference. We also make sure that the ref we're updating hasn't moved between the read and the write. Similarly, when amending a commit, make sure that the current tip of the branch is the commit we're amending.

Add git_object_short_id API to get short id string This finds a short id string that will unambiguously select the given object, starting with the core.abbrev length (usually 7) and growing until it is no longer ambiguous.

Add git_commit_amend API This adds an API to amend an existing commit, basically a shorthand for creating a new commit filling in missing parameters from the values of an existing commit. As part of this, I also added a new "sys" API to create a commit using a callback to get the parents. This allowed me to rewrite all the other commit creation APIs so that temporary allocations are no longer needed.

Add git_treebuilder_insert test and clarify doc This wasn't being tested and since it has a callback, I fixed it even though the return value of this callback is not treated like any of the other callbacks in the API.

Update git_blob_create_fromchunks callback behavr The callback to supply data chunks could return a negative value to stop creation of the blob, but we were neither using GIT_EUSER nor propagating the return value. This makes things use the new behavior of returning the negative value back to the user.

Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.
