This updates the calls that make the subdirectories for objects to use a base directory above which git_futils_mkdir won't walk any higher. This prevents attempts to mkdir all the way up to the root of the filesystem. Also, this moves the objects_dir into the loose backend structure and removes the separate allocation, plus does some preformatting of the objects_dir value to guarantee a trailing slash, etc.

This moves some of the odb_backend stuff that is related to the internals of an odb_backend implementation into include/git2/sys. Some of the stuff related to streaming I left in include/git2 because it seemed like it would be reasonably needed by a normal user who wanted to stream objects into and out of the ODB. Also, I added APIs for traversing the list of backends so that some of the tests would not need to access ODB internals.

This makes the first OID param of the ODB callback a const pointer and also propogates that change all the way to the backends.

This updates all the `foreach()` type functions across the library that take callbacks from the user to have a consistent behavior. The rules are: * A callback terminates the loop by returning any non-zero value * Once the callback returns non-zero, it will not be called again (i.e. the loop stops all iteration regardless of state) * If the callback returns non-zero, the parent fn returns GIT_EUSER * Although the parent returns GIT_EUSER, no error will be set in the library and `giterr_last()` will return NULL if called. This commit makes those changes across the library and adds tests for most of the iteration APIs to make sure that they follow the above rules.

There are three changes here: - correctly propogate error code from failed object lookups - make zlib inflate use our allocators - add OID to notfound error in ODB lookups

This migrates odb.c, odb_loose.c, odb_pack.c and pack.c to the new style of error handling. Also got the unix and win32 versions of map.c. There are some minor changes to other files but no others were completely converted. This also contains an update to filebuf so that a zeroed out filebuf will not think that the fd (== 0) is actually open (and inadvertently call close() on fd 0 if cleaned up). Lastly, this was built and tested on win32 and contains a bunch of fixes for the win32 build which was pretty broken.

This also includes droping `git_buf_lasterror` because it makes no sense in the new system. Note that in most of the places were it has been dropped, the code needs cleanup. I.e. GIT_ENOMEM is going away, so instead it should return a generic `-1` and obviously not throw anything.

Yes, this is error handling solely for `refs.c`, but some of the abstractions leak all ofer the code base.

This makes so much sense that I can't believe it hasn't been done before. Kill the old `git_fbuffer` and read files straight into `git_buf` objects. Also: In order to fully support 4GB files in 32-bit systems, the `git_buf` implementation has been changed from using `ssize_t` for storage and storing negative values on allocation failure, to using `size_t` and changing the buffer pointer to a magical pointer on allocation failure. Hopefully this won't break anything.

This is legacy compat stuff for when `deflateBound` is not defined, but we're not embedding zlib and that function is always available. Kill that with fire.

This takes all of the functions that look up simple data about paths (such as `git_futils_isdir`) and moves them over to path.h (becoming `git_path_isdir`). This leaves fileops.h just with functions that actually manipulate the filesystem or look at the file contents in some way. As part of this, the dir.h header which is really just for win32 support was moved into win32 (with some minor changes).

This converts virtually all of the places that allocate GIT_PATH_MAX buffers on the stack for manipulating paths to use git_buf objects instead. The patch is pretty careful not to touch the public API for libgit2, so there are a few places that still use GIT_PATH_MAX. This extends and changes some details of the git_buf implementation to add a couple of extra functions and to make error handling easier. This includes serious alterations to all the path.c functions, and several of the fileops.c ones, too. Also, there are a number of new functions that parallel existing ones except that use a git_buf instead of a stack-based buffer (such as git_config_find_global_r that exists alongsize git_config_find_global). This also modifies the win32 version of p_realpath to allocate whatever buffer size is needed to accommodate the realpath instead of hardcoding a GIT_PATH_MAX limit, but that change needs to be tested still.

libgit2 currently identifies loose objects as corrupt if they've been deflated using a window size less than 32Kb, because the is_zlib_compressed_data() function doesn't recognise the header byte as a zlib header. This patch makes the method tolerant of all valid window sizes (15-bit to 8-bit) - but doesn't sacrifice it's accuracy in distingushing the standard loose-object format from the experimental (now abandoned) format. It's based on a patch which has been merged into C-Git master branch: https://github.com/git/git/commit/7f684a2aff636f44a506 On memory constrained systems zlib may use a much smaller window size - working on Agit, I found that Android uses a 4KB window; giving a header byte of 0x48, not 0x78. Consequently all loose objects generated by the Android platform appear 'corrupt' :( It might appear that this patch changes isStandardFormat() to the point where it could incorrectly identify the experimental format as the standard one, but the two criteria (bitmask & checksum) can only give a false result for an experimental object where both of the following are true: 1) object size is exactly 8 bytes when uncompressed (bitmask) 2) [single-byte in-pack git type&size header] * 256 + [1st byte of the following zlib header] % 31 = 0 (checksum) As it happens, for all possible combinations of valid object type (1-4) and window bits (0-7), the only time when the checksum will be divisible by 31 is for 0x1838 - ie object type *1*, a Commit - which, due the fields all Commit objects must contain, could never be as small as 8 bytes in size. Given this, the combination of the two criteria (bitmask & checksum) always correctly determines the buffer format, and is more tolerant than the previous version.

The following files now have 0444 permissions: - loose objects - pack indexes - pack files - packs downloaded by fetch - packs downloaded by the HTTP transport And the following files now have 0666 permissions: - config files - repository indexes - reflogs - refs This brings libgit2 more in line with Git. Note that git_filebuf_commit() and git_filebuf_commit_at() have both gained a new mode parameter. The latter change fixes an important issue where filebufs created with GIT_FILEBUF_TEMPORARY received 0600 permissions (due to mkstemp(3) usage). Now we chmod() the file before renaming it into place. Tests have been added to confirm that new commit, tag, and tree objects are created with the right permissions. I don't have access to Windows, so for now I've guarded the tests with "#ifndef GIT_WIN32".

To further match how Git behaves, this change makes most of the directories libgit2 creates in a git repo have a file mode of 0777. Specifically: - Intermediate directories created with git_futils_mkpath2file() have 0777 permissions. This affects odb_loose, reflog, and refs. - The top level folder for bare repos is created with 0777 permissions. - The top level folder for non-bare repos is created with 0755 permissions. - /objects/info/, /objects/pack/, /refs/heads/, and /refs/tags/ are created with 0777 permissions. Additionally, the following changes have been made: - fileops functions that create intermediate directories have grown a new dirmode parameter. The only exception to this is filebuf's lock_file(), which unconditionally creates intermediate directories with 0777 permissions when GIT_FILEBUF_FORCE is set. - The test runner now sets the umask to 0 before running any tests. This ensurses all file mode checks are consistent across systems. - t09-tree.c now does a directory permissions check. I've avoided adding this check to other tests that might reuse existing directories from the prefabricated test repos. Because they're checked into the repo, they have 0755 permissions. - Other assorted directories created by tests have 0777 permissions.

There were quite a few places were spaces were being used instead of tabs. Try to catch them all. This should hopefully not break anything. Except for `git blame`. Oh well.

1. The license header is technically not valid if it doesn't have a copyright signature. 2. The COPYING file has been updated with the different licenses used in the project. 3. The full GPLv2 header in each file annoys me.

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.

Cleaned up the structure of the whole OS-abstraction layer. fileops.c now contains a set of utility methods for file management used by the library. These are abstractions on top of the original POSIX calls. There's a new file called `posix.c` that contains emulations/reimplementations of all the POSIX calls the library uses. These are prefixed with `p_`. There's a specific posix file for each platform (win32 and unix). All the path-related methods have been moved from `utils.c` to `path.c` and have their own prefix.
