* | vector: avoid double assertingKirill A. Shutemov2011-07-131-3/+0

| | | | | | | | The `hashfile` function has been moved to ODB, next to `git_odb_hash`. Global state has been removed from the dirent call in `status.c`, because global state is killing the rainforest and causing global warming.

* Remove unused methodsVicent Marti2011-07-098-74/+23
| | | | | | | | | The direct-writes commit left some (slow) internals methods that were no longer needed. These have been removed. Also, the Reflog code was using the old `git_signature__write`, so it has been rewritten to use a normal buffer and the new `writebuf` signature writer. It's now slightly simpler and faster.
* odb: Direct writes are backVicent Marti2011-07-0912-98/+244
| | | | | | | | | | | | | | | | | | | | | | DIRECT WRITES ARE BACK AND FASTER THAN EVER. The streaming writer to the ODB was an overkill for the smaller objects like Commit and Tags; most of the streaming logic was taking too long. This commit makes Commits, Tags and Trees to be built-up in memory, and then written to disk in 2 pushes (header + data), instead of streaming everything. This is *always* faster, even for big files (since the git_filebuf class still does streaming writes when the memory cache overflows). This is also a gazillion lines of code smaller, because we don't have to precompute the final size of the object before starting the stream (this was kind of defeating the point of streaming, anyway). Blobs are still written with full streaming instead of loading them in memory, since this is still the fastest way. A new `git_buf` class has been added. It's missing some features, but it'll get there.
* posix: Portable `vsnprintf`Vicent Marti2011-07-094-12/+42
| | | | | | | | | | | | | | | Our good, lovely folks at Microsoft decided that there was no good reason to make `vsnprintf` compilant with the C standard, so that function in Windows returns -1 on overflow, instead of returning the actual byte count needed to write the full string. We now handle this situation more gracefully with the POSIX compatibility layer, by returning the needed byte size using an auxiliary method instead of blindly resizing the target buffer until it fits. This means we can now support `printf`s of any size by allocating a temporary buffer. That's good.

* vector: Timsort all of the thingsVicent Marti2011-07-0710-81/+423
| | | | | | | | | | | | | | | | | | | | | | | | Drop the GLibc implementation of Merge Sort and replace it with Timsort. The algorithm has been tuned to work on arrays of pointers (void **), so there's no longer a need to abstract the byte-width of each element in the array. All the comparison callbacks now take pointers-to-elements, not pointers-to-pointers, so there's now one less level of dereferencing. E.g. int index_cmp(const void *a, const void *b) { - const git_index_entry *entry_a = *(const git_index_entry **)(a); + const git_index_entry *entry_a = (const git_index_entry *)(a); The result is up to a 40% speed-up when sorting vectors. Memory usage remains lineal. A new `bsearch` implementation has been added, whose callback also supplies pointer-to-elements, to uniform the Vector API again.

| * Fix network MSYS compilationCarlos Martín Nieto2011-07-062-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | MSYS/MinGW uses winsock but obviously doesn't set _MSC_VER. Use _WIN32 to decide whether to use winsock or BSD headers. Also remove these headers from src/transport_git.c altogether, as they are not needed. MSYS is very conservative, so we have to tell it that we don't care about versions of Windows lower than WindowsXP. We also need to tell CMake to add ws2_32 to the libraries list and we shouldn't add the -fPIC option, to MSYS because it complains that it does it anyway.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Index operation use git_vector_sort() to sort index entries. Since index support adding duplicates (two or more entries with the same path), it's important to preserve order of elements. Preserving order of elements allows to make decisions based on order. For example it's possible to implement function witch removes all duplicates except last added. Signed-off-by: Kirill A. Shutemov <kirill@shutemov.name>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases it's important to preserve order of elements with equal keys (stable sort). qsort(3) doesn't define order of elements with equal keys. git__msort() implements merge sort which is stable sort. Implementation taken from git. Function renamed git_qsort() -> git__msort(). Signed-off-by: Kirill A. Shutemov <kirill@shutemov.name>
