Patrick Steinhardt 05bf67b9 2016-02-23T11:16:36 openssl_stream: fix NULL pointer dereference
Patrick Steinhardt 2baf854e 2016-02-22T16:08:56 openssl_stream: fix memory leak when creating new stream
Patrick Steinhardt d0cb11e7 2016-02-22T16:01:03 remote: set error code in `create_internal` Set the error code when an error occurs in any of the called functions. This ensures we pass the error up to callers and actually free the remote when an error occurs.
Patrick Steinhardt 2afb6fa4 2016-02-22T16:05:13 rebase: plug memory leak in `rebase_alloc` Convert `rebase_alloc` to use our usual error propagation patterns, that is accept an out-parameter and return an error code that is to be checked by the caller. This allows us to use the GITERR_CHECK_ALLOC macro, which helps static analysis.
Patrick Steinhardt 0f1e2d20 2016-02-23T11:23:26 index: fix contradicting comparison The overflow check in `read_reuc` tries to verify if the `git__strtol32` parses an integer bigger than UINT_MAX. The `tmp` variable is casted to an unsigned int for this and then checked for being greater than UINT_MAX, which obviously can never be true. Fix this by instead fixing the `mode` field's size in `struct git_index_reuc_entry` to `uint32_t`. We can now parse the int with `git__strtol64`, which can never return a value bigger than `UINT32_MAX`, and additionally checking if the returned value is smaller than zero. We do not need to handle overflows explicitly here, as `git__strtol64` returns an error when the returned value would overflow.
Patrick Steinhardt 793e0855 2016-02-22T14:06:48 refdb_fs: remove unnecessary check for NULL The fail-label of `reflog_parse` explicitly checks the entry poitner for NULL before freeing it. When we jump to the label the variable has to be set to a non-NULL and valid pointer though: if the allocation fails we immediately return with an error code and if the loop was not entered we return with a success code, withouth executing the label's code. Remove the useless NULL-check to silence Coverity.
Patrick Steinhardt 42c05ed5 2016-02-23T10:02:44 path: use GITERR_CHECK_ALLOC_BUF to verify passed in buffer
Patrick Steinhardt 859ed5dd 2016-02-23T09:54:26 common: introduce GITERR_CHECK_ALLOC_BUF We commonly have to check if a git_buf has been allocated correctly or if we ran out of memory. Introduce a new macro similar to `GITERR_CHECK_ALLOC` which checks if we ran OOM and if so returns an error. Provide a `#nodef` for Coverity to mark the error case as an abort path.
Patrick Steinhardt be8479c9 2016-02-22T14:01:50 diff_print: assert patch is non-NULL When invoking `diff_print_info_init_frompatch` it is obvious that the patch should be non-NULL. We explicitly check if the variable is set and continue afterwards, happily dereferencing the potential NULL-pointer. Fix this by instead asserting that patch is set. This also silences Coverity.
Patrick Steinhardt bac52ab0 2016-02-22T13:48:45 pack-objects: return early when computing write order fails The function `compute_write_order` may return a `NULL`-pointer when an error occurs. In such cases we jump to the `done`-label where we try to clean up allocated memory. Unfortunately we try to deallocate the `write_order` array, though, which may be NULL here. Fix this error by returning early instead of jumping to the `done` label. There is no data to be cleaned up anyway.
Patrick Steinhardt d1c9a48d 2016-02-23T10:45:09 pack-objects: check realloc in try_delta with GITERR_CHECK_ALLOC
Patrick Steinhardt 7808c937 2016-02-22T15:59:15 index: plug memory leak in `read_conflict_names`
Patrick Steinhardt 2129d6df 2016-02-22T13:33:48 crlf: do not ignore GIT_PASSTHROUGH error When no payload is set for `crlf_apply` we try to compute the crlf attributes ourselves with `crlf_check`. When the function determines that the current file does not require any treatment we return the GIT_PASSTHROUGH error code without actually allocating the out-pointer, which indicates the file should not be passed through the filter. The `crlf_apply` function explicitly checks for the GIT_PASSTHROUGH return code and ignores it. This means we will try to apply the crlf-filter to the current file, leading us to dereference the unallocated payload-pointer. Fix this obviously incorrect behavior by not treating GIT_PASSTHROUGH in any special way. This is the correct thing to do anyway, as the code indicates that the file should not be passed through the filter.

Patrick Steinhardt 038d7af0 2016-02-15T11:30:48 signature: use GITERR_CHECK_ALLOC to check for OOM situation When checking for out of memory situations we usually use the GITERR_CHECK_ALLOC macro. Besides conforming to our current code base it adds the benefit of silencing errors in Coverity due to Coverity handling the macro's error path as abort.

Edward Thomson 318b825e 2016-02-16T17:11:46 index: allow read of index w/ illegal entries Allow `git_index_read` to handle reading existing indexes with illegal entries. Allow the low-level `git_index_add` to add properly formed `git_index_entry`s even if they contain paths that would be illegal for the current filesystem (eg, `AUX`). Continue to disallow `git_index_add_bypath` from adding entries that are illegal universally illegal (eg, `.git`, `foo/../bar`).
Edward Thomson 4fea9cff 2016-02-16T13:08:55 iterator: assert tree_iterator has a frame Although a `tree_iterator` that failed to be properly created does not have a frame, all other `tree_iterator`s should. Do not call `pop` in the failure case, but assert that in all other cases there is a frame.
Colin Xu a218b2f6 2016-01-22T16:03:37 Validate pointer before access the member. When Git repository at network locations, sometimes git_iterator_for_tree fails at iterator__update_ignore_case so it goes to git_iterator_free. Null pointer will crash the process if not check.

Carlos Martín Nieto eadd0f05 2016-02-16T14:06:48 commit: expose the different kinds of errors We should be checking whether the object we're looking up is a commit, and we should let the caller know whether the not-found return code comes from a bad object type or just a missing signature.

Edward Thomson f28bae0c 2016-02-15T17:16:00 rebase: persist a single in-memory index When performing an in-memory rebase, keep a single index for the duration, so that callers have the expected index lifecycle and do not hold on to an index that is free'd out from under them.
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.

Arthur Schreiber 3679ebae 2016-02-11T23:37:52 Horrible fix for #3173.
Carlos Martín Nieto 460ae11f 2016-02-11T22:19:20 commit: don't forget the last header field When we moved the logic to handle the first one, wrong loop logic was kept in place which meant we still finished early. But we now notice it because we're not reading past the last LF we find. This was not noticed before as the last field in the tested commit was multi-line which does not trigger the early break.
Edward Thomson a202e0d4 2016-02-11T10:11:21 rebase: allow custom merge_options Allow callers of rebase to specify custom merge options. This may allow custom conflict resolution, or failing fast when conflicts are detected.
Edward Thomson ee667307 2016-02-11T10:48:48 rebase: introduce inmemory rebasing Introduce the ability to rebase in-memory or in a bare repository. When `rebase_options.inmemory` is specified, the resultant `git_rebase` session will not be persisted to disk. Callers may still analyze the rebase operations, resolve any conflicts against the in-memory index and create the commits. Neither `HEAD` nor the working directory will be updated during this process.

Patrick Steinhardt a53d2e39 2016-02-09T09:58:56 pack: do not free passed in poiter on error The function `git_packfile_stream_open` tries to free the passed in stream when an error occurs. The only call site is `git_indexer_append`, though, which passes in the address of a stream struct which has not been allocated on the heap. Fix the issue by simply removing the call to free. In case of an error we did not allocate any memory yet and otherwise it should be the caller's responsibility to manage it's object's lifetime.
Carlos Martín Nieto f55eca16 2016-02-09T07:17:26 commit: also match the first header field when searching We were searching only past the first header field, which meant we were unable to find e.g. `tree` which is the first field. While here, make sure to set an error message in case we cannot find the field.
Edward Thomson 2ed855a9 2016-02-07T13:16:30 filter: avoid races during filter registration Previously we would set the global filter registry structure before adding filters to the structure, without a lock, which is quite racy. Now, register default filters during global registration and use an rwlock to read and write the filter registry (as appopriate).

As a result, we must hardcode these definitions ourselves. However, we should not use a public struct with those names, lest another library do the same thing and consumers cannot link to both.

Carlos Martín Nieto 9d81509a 2015-12-23T11:54:52 index: get rid of the locking We don't support using an index object from multiple threads at the same time, so the locking doesn't have any effect when following the rules. If not following the rules, things are going to break down anyway.

Vicent Marti ef8b7feb 2015-12-16T19:36:50 index: Also size-hint the hash table Note that we're not checking whether the resize succeeds; in OOM cases, we let it run with a "small" vector and hash table and see if by chance we can grow it dynamically as we insert the new entries. Nothing to lose really.

Vicent Marti 879ebab3 2015-12-16T12:30:52 merge: Use `git_index__fill` to populate the index Instead of calling `git_index_add` in a loop, use the new `git_index_fill` internal API to fill the index with the initial staged entries. The new `fill` helper assumes that all the entries will be unique and valid, so it can append them at the end of the entries vector and only sort it once at the end. It performs no validation checks. This prevents the quadratic behavior caused by having to sort the entries list once after every insertion.

Carlos Martín Nieto 465c3b38 2015-12-09T19:16:11 reset: perform the checkout before moving HEAD or the index This keeps the state of the workdir the same as one from HEAD, removing a source of possible confusion when calculating the work that is to be done.
Carlos Martín Nieto 21b1e015 2015-12-08T21:11:58 Merge pull request #3539 from libgit2/typedef-submodule-cb Use a typedef for the submodule_foreach callback.
joshaber eda726cf 2015-12-08T11:34:00 Use a typedef for the submodule_foreach callback. This fits with the style for the rest of the project, but more importantly, makes life easier for bindings authors who auto-generate code.
Patrick Steinhardt b057fdef 2015-12-08T16:00:35 index: always queue `remove_entry` for removal When replacing an index with a new one, we need to iterate through all index entries in order to determine which entries are equal. When it is not possible to re-use old entries for the new index, we move it into a list of entries that are to be removed and thus free'd. When we encounter a non-zero error code, though, we skip adding the current index entry to the remove-queue. `INSERT_MAP_EX`, which is the function last run before adding to the remove-queue, may return a positive non-zero code that indicates what exactly happened while inserting the element. In this case we skip adding the entry to the remove-queue but still continue the current operation, leading to a leak of the current entry. Fix this by checking for a negative return value instead of a non-zero one when we want to add the current index entry to the remove-queue.
Carlos Martín Nieto fc436469 2015-12-06T22:51:00 tree: mark a tree as already sorted The trees are sorted on-disk, so we don't have to go over them again. This cuts almost a fifth of time spent parsing trees.
Edward Thomson 5d1f31c6 2015-12-03T17:42:52 Merge pull request #3530 from libgit2/cmn/parse-mode tree: use a specialised mode parse function
Edward Thomson 626f9e24 2015-12-03T16:27:15 index: canonicalize inserted paths safely When adding to the index, we look to see if a portion of the given path matches a portion of a path in the index. If so, we will use the existing path information. For example, when adding `foo/bar.c`, if there is an index entry to `FOO/other` and the filesystem is case insensitive, then we will put `bar.c` into the existing tree instead of creating a new one with a different case. Use `strncmp` to do that instead of `memcmp`. When we `bsearch` into the index, we locate the position where the new entry would go. The index entry at that position does not necessarily have a relation to the entry we're adding, so we cannot make assumptions and use `memcmp`. Instead, compare them as strings. When canonicalizing paths, we look for the first index entry that matches a given substring.
Carlos Martín Nieto 0174f21b 2015-12-02T18:56:31 tree: use a specialised mode parse function Instead of going out to strtol, which is made to parse generic numbers, copy a parse function from git which is specialised for file modes.

Patrick Steinhardt 9487585d 2015-12-01T14:19:29 tree: mark cloned tree entries as un-pooled When duplicating a `struct git_tree_entry` with `git_tree_entry_dup` the resulting structure is not allocated inside a memory pool. As we do a 1:1 copy of the original struct, though, we also copy the `pooled` field, which is set to `true` for pooled entries. This results in a huge memory leak as we never free tree entries that were duplicated from a pooled tree entry. Fix this by marking the newly duplicated entry as un-pooled.
Patrick Steinhardt 254e0a33 2015-11-24T13:43:43 diff: include commit message when formatting patch When formatting a patch as email we do not include the commit's message in the formatted patch output. Implement this and add a test that verifies behavior.
Patrick Steinhardt 7f8fe1d4 2015-12-01T10:03:56 commit: introduce `git_commit_body` It is already possible to get a commit's summary with the `git_commit_summary` function. It is not possible to get the remaining part of the commit message, that is the commit message's body. Fix this by introducing a new function `git_commit_body`.
Patrick Steinhardt 944dbd12 2015-11-24T10:52:17 blame: use size_t for line counts in git_blame__entry The `git_blame__entry` struct keeps track of line counts with `int` fields. Since `int` is only guaranteed to be at least 16 bits we may overflow on certain platforms when line counts exceed 2^15. Fix this by instead storing line counts in `size_t`.
