c512d58f	2019-06-15T22:26:23	win32: cast WinAPI to void * before casting GetProcAddress is prototyped to return a `FARPROC`, which is meant to be a generic function pointer. It's literally `int (FAR WINAPI * FARPROC)()` which gcc complains if you attempt to cast to a `void ()(GIT_SRWLOCK )`. Cast to a `void *` before casting to avoid warnings about the arguments.

a9f57629	2019-06-13T15:03:00	wildmatch: import wildmatch from git.git In commit 70a8fc999d (stop using fnmatch (either native or compat), 2014-02-15), upstream git has switched over all code from their internal fnmatch copy to its new wildmatch code. We haven't followed suit, and thus have developed some incompatibilities in how we match regular expressions. Import git's wildmatch from v2.22.0 and add a test suite based on their t3070-wildmatch.sh tests.

Recent tries to do that escalated quite fast to a set of different CMake checks, implementations, fallbacks, etc., which started to look real awkward to maintain. In fact, `p_fallocate` had only been introduced in commit 4e3949b73 (tests: test that largefiles can be read through the tree API, 2019-01-30) to support a test with large files, but given the maintenance costs it just seems not to be worht it. As we have removed the sole user of `p_fallocate` in the previous commit, let's drop it altogether.

0b5ba0d7	2019-06-06T16:36:23	Rename opt init functions to `options_init` In libgit2 nomenclature, when we need to verb a direct object, we name a function `git_directobject_verb`. Thus, if we need to init an options structure named `git_foo_options`, then the name of the function that does that should be `git_foo_options_init`. The previous names of `git_foo_init_options` is close - it _sounds_ as if it's initializing the options of a `foo`, but in fact `git_foo_options` is its own noun that should be respected. Deprecate the old names; they'll now call directly to the new ones.

b055a6b5	2019-01-13T01:24:39	tests: regex: add test with LC_COLLATE being set While we already have a test for `p_regexec` with `LC_CTYPE` being modified, `regexec` also alters behavior as soon as `LC_COLLATE` is being modified. Most importantly, `LC_COLLATE` changes the way how ranges are interpreted to just not handling them at all. Thus, ensure that either we use `regcomp_l` to avoid this, or that we've fallen back to our builtin regex functionality which also behaves properly.

18cf5698	2018-12-01T09:37:40	maps: provide high-level iteration interface Currently, our headers need to leak some implementation details of maps due to their direct use of indices in the implementation of their foreach macros. This makes it impossible to completely hide the map structures away, and also makes it impossible to include the khash implementation header in the C files of the respective map only. This is now being fixed by providing a high-level iteration interface `map_iterate`, which takes as inputs the map that shall be iterated over, an iterator as well as the locations where keys and values shall be put into. For simplicity's sake, the iterator is a simple `size_t` that shall initialized to `0` on the first call. All existing foreach macros are then adjusted to make use of this new function.
2e0a3048	2019-01-23T10:48:55	oidmap: introduce high-level setter for key/value pairs Currently, one would use either `git_oidmap_insert` to insert key/value pairs into a map or `git_oidmap_put` to insert a key only. These function have historically been macros, which is why their syntax is kind of weird: instead of returning an error code directly, they instead have to be passed a pointer to where the return value shall be stored. This does not match libgit2's common idiom of directly returning error codes.Furthermore, `git_oidmap_put` is tightly coupled with implementation details of the map as it exposes the index of inserted entries. Introduce a new function `git_oidmap_set`, which takes as parameters the map, key and value and directly returns an error code. Convert all trivial callers of `git_oidmap_insert` and `git_oidmap_put` to make use of it.
9694ef20	2018-12-17T09:01:53	oidmap: introduce high-level getter for values The current way of looking up an entry from a map is tightly coupled with the map implementation, as one first has to look up the index of the key and then retrieve the associated value by using the index. As a caller, you usually do not care about any indices at all, though, so this is more complicated than really necessary. Furthermore, it invites for errors to happen if the correct error checking sequence is not being followed. Introduce a new high-level function `git_oidmap_get` that takes a map and a key and returns a pointer to the associated value if such a key exists. Otherwise, a `NULL` pointer is returned. Adjust all callers that can trivially be converted.

7e926ef3	2018-11-30T12:14:43	maps: provide a uniform entry count interface There currently exist two different function names for getting the entry count of maps, where offmaps offset and string maps use `num_entries` and OID maps use `size`. In most programming languages with built-in map types, this is simply called `size`, which is also shorter to type. Thus, this commit renames the other two functions `num_entries` to match the common way and adjusts all callers.
351eeff3	2019-01-23T10:42:46	maps: use uniform lifecycle management functions Currently, the lifecycle functions for maps (allocation, deallocation, resize) are not named in a uniform way and do not have a uniform function signature. Rename the functions to fix that, and stick to libgit2's naming scheme of saying `git_foo_new`. This results in the following new interface for allocation: - `int git_<t>map_new(git_<t>map *out)` to allocate a new map, returning an error code if we ran out of memory - `void git_<t>map_free(git_<t>map map)` to free a map - `void git_<t>map_clear(git<t>map *map)` to remove all entries from a map This commit also fixes all existing callers.

df2cc108	2018-11-18T10:29:07	stream: provide generic registration API Update the new stream registration API to be `git_stream_register` which takes a registration structure and a TLS boolean. This allows callers to register non-TLS streams as well as TLS streams. Provide `git_stream_register_tls` that takes just the init callback for backward compatibliity.
43b592ac	2018-10-25T08:49:01	tls: introduce a wrap function Introduce `git_tls_stream_wrap` which will take an existing `stream` with an already connected socket and begin speaking TLS on top of it. This is useful if you've built a connection to a proxy server and you wish to begin CONNECT over it to tunnel a TLS connection. Also update the pluggable TLS stream layer so that it can accept a registration structure that provides an `init` and `wrap` function, instead of a single initialization function.

4209a512	2018-11-14T12:04:42	strntol: fix out-of-bounds reads when parsing numbers with leading sign When parsing a number, we accept a leading plus or minus sign to return a positive or negative number. When the parsed string has such a leading sign, we set up a flag indicating that the number is negative and advance the pointer to the next character in that string. This misses updating the number of bytes in the string, though, which is why the parser may later on do an out-of-bounds read. Fix the issue by correctly updating both the pointer and the number of remaining bytes. Furthermore, we need to check whether we actually have any bytes left after having advanced the pointer, as otherwise the auto-detection of the base may do an out-of-bonuds access. Add a test that detects the out-of-bound read. Note that this is not actually security critical. While there are a lot of places where the function is called, all of these places are guarded or irrelevant: - commit list: this operates on objects from the ODB, which are always NUL terminated any may thus not trigger the off-by-one OOB read. - config: the configuration is NUL terminated. - curl stream: user input is being parsed that is always NUL terminated - index: the index is read via `git_futils_readbuffer`, which always NUL terminates it. - loose objects: used to parse the length from the object's header. As we check previously that the buffer contains a NUL byte, this is safe. - rebase: this parses numbers from the rebase instruction sheet. As the rebase code uses `git_futils_readbuffer`, the buffer is always NUL terminated. - revparse: this parses a user provided buffer that is NUL terminated. - signature: this parser the header information of objects. As objects read from the ODB are always NUL terminated, this is a non-issue. The constructor `git_signature_from_buffer` does not accept a length parameter for the buffer, so the buffer needs to be NUL terminated, as well. - smart transport: the buffer that is parsed is NUL terminated - tree cache: this parses the tree cache from the index extension. The index itself is read via `git_futils_readbuffer`, which always NUL terminates it. - winhttp transport: user input is being parsed that is always NUL terminated
50d09407	2018-10-29T18:05:27	strntol: fix detection and skipping of base prefixes The `git__strntol` family of functions has the ability to auto-detect a number's base if the string has either the common '0x' prefix for hexadecimal numbers or '0' prefix for octal numbers. The detection of such prefixes and following handling has two major issues though that are being fixed in one go now. - We do not do any bounds checking previous to verifying the '0x' base. While we do verify that there is at least one digit available previously, we fail to verify that there are two digits available and thus may do an out-of-bounds read when parsing this two-character-prefix. - When skipping the prefix of such numbers, we only update the pointer length without also updating the number of remaining bytes. Thus if we try to parse a number '0x1' of total length 3, we will first skip the first two bytes and then try to read 3 bytes starting at '1'. Fix both issues by disentangling the logic. Instead of doing the detection and skipping of such prefixes in one go, we will now first try to detect the base while also honoring how many bytes are left. Only if we have a valid base that is either 8 or 16 and have one of the known prefixes, we will now advance the pointer and update the remaining bytes in one step. Add some tests that verify that no out-of-bounds parsing happens and that autodetection works as advertised.
41863a00	2018-10-29T17:19:58	strntol: fix out-of-bounds read when skipping leading spaces The `git__strntol` family of functions accepts leading spaces and will simply skip them. The skipping will not honor the provided buffer's length, though, which may lead it to read outside of the provided buffer's bounds if it is not a simple NUL-terminated string. Furthermore, if leading space is trimmed, the function will further advance the pointer but not update the number of remaining bytes, which may also lead to out-of-bounds reads. Fix the issue by properly paying attention to the buffer length and updating it when stripping leading whitespace characters. Add a test that verifies that we won't read past the provided buffer length.

83e8a6b3	2018-10-18T16:08:46	util: provide `git__memmem` function Unfortunately, neither the `memmem` nor the `strnstr` functions are part of any C standard but are merely extensions of C that are implemented by e.g. glibc. Thus, there is no standardized way to search for a string in a block of memory with a limited size, and using `strstr` is to be considered unsafe in case where the buffer has not been sanitized. In fact, there are some uses of `strstr` in exactly that unsafe way in our codebase. Provide a new function `git__memmem` that implements the `memmem` semantics. That is in a given haystack of `n` bytes, search for the occurrence of a byte sequence of `m` bytes and return a pointer to the first occurrence. The implementation chosen is the "Not So Naive" algorithm from [1]. It was chosen as the implementation is comparably simple while still being reasonably efficient in most cases. Preprocessing happens in constant time and space, searching has a time complexity of O(n*m) with a slightly sub-linear average case. [1]: http://www-igm.univ-mlv.fr/~lecroq/string/
ea19efc1	2018-10-18T15:08:56	util: fix out of bounds read in error message When an integer that is parsed with `git__strntol32` is too big to fit into an int32, we will generate an error message that includes the actual string that failed to parse. This does not acknowledge the fact that the string may either not be NUL terminated or alternative include additional characters after the number that is to be parsed. We may thus end up printing characters into the buffer that aren't the number or, worse, read out of bounds. Fix the issue by utilizing the `endptr` that was set by `git__strntol64`. This pointer is guaranteed to be set to the first character following the number, and we can thus use it to compute the width of the number that shall be printed. Create a test to verify that we correctly truncate the number.

This may leave stale files and/or directories after having run tests, confusing subsequent tests that expect a pristine test environment. Most importantly, it may cause the test initialization to fail which expects being able to re-create the testing hierarchy before each test in case where another test hasn't cleaned up after itself. Fix the issue by adding a cleanup function that removes the temporary testing hierarchy after each test if it still exists.

89a34828	2017-06-16T13:34:43	diff: implement function to calculate patch ID The upstream git project provides the ability to calculate a so-called patch ID. Quoting from git-patch-id(1): A "patch ID" is nothing but a sum of SHA-1 of the file diffs associated with a patch, with whitespace and line numbers ignored." Patch IDs can be used to identify two patches which are probably the same thing, e.g. when a patch has been cherry-picked to another branch. This commit implements a new function `git_diff_patchid`, which gets a patch and derives an OID from the diff. Note the different terminology here: a patch in libgit2 are the differences in a single file and a diff can contain multiple patches for different files. The implementation matches the upstream implementation and should derive the same OID for the same diff. In fact, some code has been directly derived from the upstream implementation. The upstream implementation has two different modes to calculate patch IDs, which is the stable and unstable mode. The old way of calculating the patch IDs was unstable in a sense that a different ordering the diffs was leading to different results. This oversight was fixed in git 1.9, but as git tries hard to never break existing workflows, the old and unstable way is still default. The newer and stable way does not care for ordering of the diff hunks, and in fact it is the mode that should probably be used today. So right now, we only implement the stable way of generating the patch ID.

Our current check does not do the right thing, though, in that it does not honor that our `pos` variable counts the position down instead of up. As such, we will require too much memory for small varints and not enough memory for big varints. Fix the issue by correctly calculating the required size as `(sizeof(varint) - pos)`. Add a test which failed before.

5d59520c	2017-02-07T20:30:11	path: get correct dirname for Windows root Getting the dirname of a filesystem root should return the filesystem root itself. E.g. the dirname of "/" is always "/". On Windows, we emulate this behavior and as such, we should return e.g. "C:/" if calling dirname on "C:/". But we currently fail to do so and instead return ".", as we do not check if we actually have a Windows prefix before stripping off the last directory component. Fix this by calling out to `win32_prefix_length` immediately after stripping trailing slashes, returning early if we have a prefix.

Since `git_thread_create` is internal-only, keep this sanity check. Flip the invocation so that we `git_libgit2_init` before our thread tests and `git_libgit2_shutdown` again after.

95fa3880	2016-10-28T16:07:40	pqueue: resolve possible NULL pointer dereference The `git_pqueue` struct allows being fixed in its total number of entries. In this case, we simply throw away items that are inserted into the priority queue by examining wether the new item to be inserted has a higher priority than the previous smallest one. This feature somewhat contradicts our pqueue implementation in that it is allowed to not have a comparison function. In fact, we also fail to check if the comparison function is actually set in the case where we add a new item into a fully filled fixed-size pqueue. As we cannot determine which item is the smallest item in absence of a comparison function, we fix the `NULL` pointer dereference by simply dropping all new items which are about to be inserted into a full fixed-size pqueue.

posix: remove `p_fallocate` abstraction By now, we have repeatedly failed to provide a nice cross-platform implementation of `p_fallocate`. Recent tries to do that escalated quite fast to a set of different CMake checks, implementations, fallbacks, etc., which started to look real awkward to maintain. In fact, `p_fallocate` had only been introduced in commit 4e3949b73 (tests: test that largefiles can be read through the tree API, 2019-01-30) to support a test with large files, but given the maintenance costs it just seems not to be worht it. As we have removed the sole user of `p_fallocate` in the previous commit, let's drop it altogether.

apply: add an options struct initializer

0b5ba0d7

2019-06-06T16:36:23

Rename opt init functions to `options_init` In libgit2 nomenclature, when we need to verb a direct object, we name a function `git_directobject_verb`. Thus, if we need to init an options structure named `git_foo_options`, then the name of the function that does that should be `git_foo_options_init`. The previous names of `git_foo_init_options` is close - it _sounds_ as if it's initializing the options of a `foo`, but in fact `git_foo_options` is its own noun that should be respected. Deprecate the old names; they'll now call directly to the new ones.

maps: provide high-level iteration interface Currently, our headers need to leak some implementation details of maps due to their direct use of indices in the implementation of their foreach macros. This makes it impossible to completely hide the map structures away, and also makes it impossible to include the khash implementation header in the C files of the respective map only. This is now being fixed by providing a high-level iteration interface `map_iterate`, which takes as inputs the map that shall be iterated over, an iterator as well as the locations where keys and values shall be put into. For simplicity's sake, the iterator is a simple `size_t` that shall initialized to `0` on the first call. All existing foreach macros are then adjusted to make use of this new function.

These function have historically been macros, which is why their syntax is kind of weird: instead of returning an error code directly, they instead have to be passed a pointer to where the return value shall be stored. This does not match libgit2's common idiom of directly returning error codes.Furthermore, `git_oidmap_put` is tightly coupled with implementation details of the map as it exposes the index of inserted entries. Introduce a new function `git_oidmap_set`, which takes as parameters the map, key and value and directly returns an error code. Convert all trivial callers of `git_oidmap_insert` and `git_oidmap_put` to make use of it.

Furthermore, it invites for errors to happen if the correct error checking sequence is not being followed.

maps: provide a uniform entry count interface There currently exist two different function names for getting the entry count of maps, where offmaps offset and string maps use `num_entries` and OID maps use `size`. In most programming languages with built-in map types, this is simply called `size`, which is also shorter to type. Thus, this commit renames the other two functions `num_entries` to match the common way and adjusts all callers.

Rename the functions to fix that, and stick to libgit2's naming scheme of saying `git_foo_new`. This results in the following new interface for allocation: - `int git_<t>map_new(git_<t>map **out)` to allocate a new map, returning an error code if we ran out of memory - `void git_<t>map_free(git_<t>map *map)` to free a map - `void git_<t>map_clear(git<t>map *map)` to remove all entries from a map This commit also fixes all existing callers.

strntol: fix out-of-bounds reads when parsing numbers with leading sign When parsing a number, we accept a leading plus or minus sign to return a positive or negative number. When the parsed string has such a leading sign, we set up a flag indicating that the number is negative and advance the pointer to the next character in that string. This misses updating the number of bytes in the string, though, which is why the parser may later on do an out-of-bounds read. Fix the issue by correctly updating both the pointer and the number of remaining bytes. Furthermore, we need to check whether we actually have any bytes left after having advanced the pointer, as otherwise the auto-detection of the base may do an out-of-bonuds access. Add a test that detects the out-of-bound read. Note that this is not actually security critical. While there are a lot of places where the function is called, all of these places are guarded or irrelevant: - commit list: this operates on objects from the ODB, which are always NUL terminated any may thus not trigger the off-by-one OOB read. - config: the configuration is NUL terminated. - curl stream: user input is being parsed that is always NUL terminated - index: the index is read via `git_futils_readbuffer`, which always NUL terminates it. - loose objects: used to parse the length from the object's header. As we check previously that the buffer contains a NUL byte, this is safe. - rebase: this parses numbers from the rebase instruction sheet. As the rebase code uses `git_futils_readbuffer`, the buffer is always NUL terminated. - revparse: this parses a user provided buffer that is NUL terminated. - signature: this parser the header information of objects. As objects read from the ODB are always NUL terminated, this is a non-issue. The constructor `git_signature_from_buffer` does not accept a length parameter for the buffer, so the buffer needs to be NUL terminated, as well. - smart transport: the buffer that is parsed is NUL terminated - tree cache: this parses the tree cache from the index extension. The index itself is read via `git_futils_readbuffer`, which always NUL terminates it. - winhttp transport: user input is being parsed that is always NUL terminated

strntol: fix detection and skipping of base prefixes The `git__strntol` family of functions has the ability to auto-detect a number's base if the string has either the common '0x' prefix for hexadecimal numbers or '0' prefix for octal numbers. The detection of such prefixes and following handling has two major issues though that are being fixed in one go now. - We do not do any bounds checking previous to verifying the '0x' base. While we do verify that there is at least one digit available previously, we fail to verify that there are two digits available and thus may do an out-of-bounds read when parsing this two-character-prefix. - When skipping the prefix of such numbers, we only update the pointer length without also updating the number of remaining bytes. Thus if we try to parse a number '0x1' of total length 3, we will first skip the first two bytes and then try to read 3 bytes starting at '1'. Fix both issues by disentangling the logic. Instead of doing the detection and skipping of such prefixes in one go, we will now first try to detect the base while also honoring how many bytes are left. Only if we have a valid base that is either 8 or 16 and have one of the known prefixes, we will now advance the pointer and update the remaining bytes in one step. Add some tests that verify that no out-of-bounds parsing happens and that autodetection works as advertised.

strntol: fix out-of-bounds read when skipping leading spaces The `git__strntol` family of functions accepts leading spaces and will simply skip them. The skipping will not honor the provided buffer's length, though, which may lead it to read outside of the provided buffer's bounds if it is not a simple NUL-terminated string. Furthermore, if leading space is trimmed, the function will further advance the pointer but not update the number of remaining bytes, which may also lead to out-of-bounds reads. Fix the issue by properly paying attention to the buffer length and updating it when stripping leading whitespace characters. Add a test that verifies that we won't read past the provided buffer length.

util: provide `git__memmem` function Unfortunately, neither the `memmem` nor the `strnstr` functions are part of any C standard but are merely extensions of C that are implemented by e.g. glibc. Thus, there is no standardized way to search for a string in a block of memory with a limited size, and using `strstr` is to be considered unsafe in case where the buffer has not been sanitized. In fact, there are some uses of `strstr` in exactly that unsafe way in our codebase. Provide a new function `git__memmem` that implements the `memmem` semantics. That is in a given haystack of `n` bytes, search for the occurrence of a byte sequence of `m` bytes and return a pointer to the first occurrence. The implementation chosen is the "Not So Naive" algorithm from [1]. It was chosen as the implementation is comparably simple while still being reasonably efficient in most cases. Preprocessing happens in constant time and space, searching has a time complexity of O(n*m) with a slightly sub-linear average case. [1]: http://www-igm.univ-mlv.fr/~lecroq/string/

util: fix out of bounds read in error message When an integer that is parsed with `git__strntol32` is too big to fit into an int32, we will generate an error message that includes the actual string that failed to parse. This does not acknowledge the fact that the string may either not be NUL terminated or alternative include additional characters after the number that is to be parsed. We may thus end up printing characters into the buffer that aren't the number or, worse, read out of bounds. Fix the issue by utilizing the `endptr` that was set by `git__strntol64`. This pointer is guaranteed to be set to the first character following the number, and we can thus use it to compute the width of the number that shall be printed. Create a test to verify that we correctly truncate the number.

While this is totally fine in this test, as the pointer's value is never being used in the first place, we can trivially avoid the warning by instead just inserting a pointer for a variable allocated on the stack into the vector.

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.

util: introduce `git__prefixncmp` and consolidate implementations Introduce `git_prefixncmp` that will search up to the first `n` characters of a string to see if it is prefixed by another string. This is useful for examining if a non-null terminated character array is prefixed by a particular substring. Consolidate the various implementations of `git__prefixcmp` around a single core implementation and add some test cases to validate its behavior.

diff: implement function to calculate patch ID The upstream git project provides the ability to calculate a so-called patch ID. Quoting from git-patch-id(1): A "patch ID" is nothing but a sum of SHA-1 of the file diffs associated with a patch, with whitespace and line numbers ignored." Patch IDs can be used to identify two patches which are probably the same thing, e.g. when a patch has been cherry-picked to another branch. This commit implements a new function `git_diff_patchid`, which gets a patch and derives an OID from the diff. Note the different terminology here: a patch in libgit2 are the differences in a single file and a diff can contain multiple patches for different files. The implementation matches the upstream implementation and should derive the same OID for the same diff. In fact, some code has been directly derived from the upstream implementation. The upstream implementation has two different modes to calculate patch IDs, which is the stable and unstable mode. The old way of calculating the patch IDs was unstable in a sense that a different ordering the diffs was leading to different results. This oversight was fixed in git 1.9, but as git tries hard to never break existing workflows, the old and unstable way is still default. The newer and stable way does not care for ordering of the diff hunks, and in fact it is the mode that should probably be used today. So right now, we only implement the stable way of generating the patch ID.

varint: fix computation for remaining buffer space When encoding varints to a buffer, we want to remain sure that the required buffer space does not exceed what is actually available. Our current check does not do the right thing, though, in that it does not honor that our `pos` variable counts the position down instead of up. As such, we will require too much memory for small varints and not enough memory for big varints. Fix the issue by correctly calculating the required size as `(sizeof(varint) - pos)`. Add a test which failed before.

path: ensure dirname on Win32 prefix always has a trailing '/' When calling `git_path_dirname_r` on a Win32 prefix, e.g. a drive or network share prefix, we always want to return the trailing '/'. This does not work currently when passing in a path like 'C:', where the '/' would not be appended correctly. Fix this by appending a '/' if we try to normalize a Win32 prefix and there is no trailing '/'.

path: get correct dirname for Windows root Getting the dirname of a filesystem root should return the filesystem root itself. E.g. the dirname of "/" is always "/". On Windows, we emulate this behavior and as such, we should return e.g. "C:/" if calling dirname on "C:/". But we currently fail to do so and instead return ".", as we do not check if we actually have a Windows prefix before stripping off the last directory component. Fix this by calling out to `win32_prefix_length` immediately after stripping trailing slashes, returning early if we have a prefix.

core::init tests: reverse init/shutdown We want a predictable number of initializations in our multithreaded init test, but we also want to make sure that we have _actually_ initialized `git_libgit2_init` before calling `git_thread_create` (since it now has a sanity check that `git_libgit2_init` has been called). Since `git_thread_create` is internal-only, keep this sanity check. Flip the invocation so that we `git_libgit2_init` before our thread tests and `git_libgit2_shutdown` again after.

This tries to catch races and makes sure that it is possible to reinitialize libgit2 multiple times. After deinitializing libgit2, we have to make sure to setup options required for testing. Currently, this only includes setting up the configuration search path again. Before, this has been set up once in `tests/main.c`.

pqueue: resolve possible NULL pointer dereference The `git_pqueue` struct allows being fixed in its total number of entries. In this case, we simply throw away items that are inserted into the priority queue by examining wether the new item to be inserted has a higher priority than the previous smallest one. This feature somewhat contradicts our pqueue implementation in that it is allowed to not have a comparison function. In fact, we also fail to check if the comparison function is actually set in the case where we add a new item into a fully filled fixed-size pqueue. As we cannot determine which item is the smallest item in absence of a comparison function, we fix the `NULL` pointer dereference by simply dropping all new items which are about to be inserted into a full fixed-size pqueue.
