Carlos Martín Nieto d8fcafb2 2016-03-16T19:05:11 Split the page size from the mmap alignment While often similar, these are not the same on Windows. We want to use the page size on Windows for the pools, but for mmap we need to use the allocation granularity as the alignment. On the other platforms these values remain the same.
Marc Strapetz 9a668abd 2016-03-15T18:32:37 Option "LIBGIT2_PREFIX" to set the CMAKE's TARGET_PROPERTIES PREFIX This is especially useful in combination with MinGW to yield the Windows-compliant DLL name "git2.dll" instead of "libgit2.dll"
Dirkjan Bussink cdde081b 2016-03-14T12:41:41 Use general cl_git_fail because the error is generic
Patrick Steinhardt 18c4ae70 2016-03-10T17:05:30 filebuf: handle write error in `lock_file` When writing to a file with locking not check if writing the locked file actually succeeds. Fix the issue by returning error code and message when writing fails.
Patrick Steinhardt f17ed637 2016-03-10T16:42:55 blame: handle error when resoling HEAD in normalize_options When normalizing options we try to look up HEAD's OID. While this action may fail in malformed repositories we never check the return value of the function. Fix the issue by converting `normalize_options` to actually return an error and handle the error in `git_blame_file`.
Dirkjan Bussink 4e91020c 2016-03-14T12:41:12 Start error string with lower case character
Marc Strapetz f587f38c 2016-03-15T18:20:32 CMake: do not overwrite but only append to CMAKE_C_FLAGS_DEBUG This is useful to force "smart" IDEs (like CLIon) to use debug flag -g even it may have decided that "-D_DEBUG" (which is already present) is sufficient.
Dirkjan Bussink c1ec732f 2016-03-14T12:02:00 Setup better defaults for OpenSSL ciphers This ensures that when using OpenSSL a safe default set of ciphers is selected. This is done so that the client communicates securely and we don't accidentally enable unsafe ciphers like RC4, or even worse some old export ciphers. Implements the first part of https://github.com/libgit2/libgit2/issues/3682
Patrick Steinhardt 89e7604c 2016-03-10T17:21:02 config_cache: check return value of `git_config__lookup_entry` Callers of `git_config__cvar` already handle the case where the function returns an error due to a failed configuration variable lookup, but we are actually swallowing errors when calling `git_config__lookup_entry` inside of the function. Fix this by returning early when `git_config__lookup_entry` returns an error. As we call `git_config__lookup_entry` with `no_errors == false` which leads us to call `get_entry` with `GET_NO_MISSING` we will not return early when the lookup fails due to a missing entry. Like this we are still able to set the default value of the cvar and exit successfully.
Patrick Steinhardt e114bbac 2016-03-01T16:00:49 index: assert required OID are non-NULL
Patrick Steinhardt d0780b81 2016-03-01T15:35:45 object: avoid call of memset with ouf of bounds pointer When computing a short OID we do this by first copying the leading parts into the new OID structure and then setting the trailing part to zero. In the case of the desired length being `GIT_OID_HEXSZ - 1` we will call `memset` with an out of bounds pointer and a length of 0. While this seems to cause no problems for common platforms the C89 standard does not explicitly state that calling `memset` with an out of bounds pointer and length of 0 is valid. Fix the potential issue by using the newly introduced `git_oid__cpy_prefix` function.
Patrick Steinhardt dd78d7d1 2016-03-10T16:33:49 blame_git: handle error returned by `git_commit_parent`
Patrick Steinhardt 8d3ee96a 2016-03-10T16:11:51 refdb_fs: fail if refcache returns NULL pointer We usually check entries returned by `git_sortedcache_entry` for NULL pointers. As we have a write lock in `packed_write`, though, it really should not happen that the function returns NULL. Assert that ref is not NULL to silence a Coverity warning.
Patrick Steinhardt 0b357e2e 2016-03-02T01:50:34 coverity: report errors when uploading tarball Curl by default does not report errors by setting the error code. As the upload can fail through several conditions (e.g. the rate limit, leading to unauthorized access) we should indicate this information in Travis CI. To improve upon the behavior, use `--write-out=%{http_code}` to write out the HTTP code in addition to the received body and return an error if the code does not equal 201.
Patrick Steinhardt 851c51ab 2016-03-10T10:40:47 diff_tform: fix potential NULL pointer access When the user passes in a diff which has no repository associated we may call `git_config__get_int_force` with a NULL-pointer configuration. Even though `git_config__get_int_force` is designed to swallow errors, it is not intended to be called with a NULL pointer configuration. Fix the issue by only calling `git_config__get_int_force` only when configuration could be retrieved from the repository.
Patrick Steinhardt d96c0638 2016-03-01T19:11:33 submodule: avoid passing NULL pointers to strncmp In C89 it is undefined behavior to pass `NULL` pointers to `strncmp` and later on in C99 it has been explicitly stated that functions with an argument declared as `size_t nmemb` specifying the array length shall always have valid parameters, no matter if `nmemb` is 0 or not (see ISO 9899 §7.21.1.2). The function `str_equal_no_trailing_slash` always passes its parameters to `strncmp` if their lengths match. This means if one parameter is `NULL` and the other one either `NULL` or a string with length 0 we will pass the pointers to `strncmp` and cause undefined behavior. Fix this by explicitly handling the case when both lengths are 0.

Piet Brauer 0370dae1 2016-02-25T18:15:02 Check for __CLANG_INTTYPES_H This fixes an issue in Xcode 7.3 in objective-git where we get the error "Include of non-modular header file in module". Not importing this header again fixes the issue.
Patrick Steinhardt e39ad747 2016-03-01T14:40:17 config_file: handle missing quotation marks in section header When parsing a section header we expect something along the format of '[section "subsection"]'. When a section is mal-formated and is entirely missing its quotation marks we catch this case by observing that `strchr(line, '"') - strrchr(line, '"') = NULL - NULL = 0` and error out. Unfortunately, the error message is misleading though, as we state that we are missing the closing quotation mark while we in fact miss both quotation marks. Improve the error message by explicitly checking if the first quotation mark could be found and, if not, stating that quotation marks are completely missing.

Carlos Martín Nieto 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.

Carlos Martín Nieto 25205737 2016-03-03T10:08:00 test: make sure we retry the auth callback on all platforms We were missing this test on Windows, which meant we didn't notice that we never fixed the single authentication attempt it tries, nor its wrong return code. Enable this for the unix platforms as well over HTTP. We previously were doing it locally but disabled it on OS X due to issues with its sshd not accepting password authentication.

We will use that and use a macro to expand to the `st_mtim` / `st_mtimespec` definition on other systems (much like the existing `st_mtime` backcompat definition).
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.

Edward Thomson 04c3b35f 2016-02-23T13:02:07 map: use `giterr_set` internally Use the `giterr_set` function, which actually supports `GITERR_OS`. The `giterr_set_str` function is exposed for external users and will not append the operating system's error message.
Patrick Steinhardt 32f07984 2016-02-23T11:07:03 diff_tform: fix potential NULL pointer access The `normalize_find_opts` function in theory allows for the incoming diff to have no repository. When the caller does not pass in diff find options or if the GIT_DIFF_FIND_BY_CONFIG value is set, though, we try to derive the configuration from the diff's repository configuration without first verifying that the repository is actually set to a non-NULL value. Fix this issue by explicitly checking if the repository is set and if it is not, fall back to a default value of GIT_DIFF_FIND_RENAMES.

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 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 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 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 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 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.
