Decouple index iterator sort from index
This makes the index iterator honor the GIT_ITERATOR_IGNORE_CASE
and GIT_ITERATOR_DONT_IGNORE_CASE flags without modifying the
index data itself. To take advantage of this, I had to export a
number of the internal index entry comparison functions. I also
wrote some new tests to exercise the capability.

Initial Implementation of progress reports during push
This adds the basics of progress reporting during push. While progress
for all aspects of a push operation are not reported with this change,
it lays the foundation to add these later. Push progress reporting
can be improved in the future - and consumers of the API should
just get more accurate information at that point.
The main areas where this is lacking are:
1) packbuilding progress: does not report progress during deltafication,
as this involves coordinating progress from multiple threads.
2) network progress: reports progress as objects and bytes are going
to be written to the subtransport (instead of as client gets
confirmation that they have been received by the server) and leaves
out some of the bytes that are transfered as part of the push protocol.
Basically, this reports the pack bytes that are written to the
subtransport. It does not report the bytes sent on the wire that
are received by the server. This should be a good estimate of
progress (and an improvement over no progress).

Major rename detection changes
After doing further profiling, I found that a lot of time was
being spent attempting to insert hashes into the file hash
signature when using the rolling hash because the rolling hash
approach generates a hash per byte of the file instead of one
per run/line of data.
To optimize this, I decided to convert back to a run-based file
signature algorithm which would be more like core Git.
After changing this, a number of the existing tests started to
fail. In some cases, this appears to have been because the test
was coded to be too specific to the particular results of the file
similarity metric and in some cases there appear to have been bugs
in the core rename detection code where only by the coincidence
of the file similarity scoring were the expected results being
generated.
This renames all the variables in the core rename detection code
to be more consistent and hopefully easier to follow which made it
a bit easier to reason about the behavior of that code and fix the
problems that I was seeing. I think it's in better shape now.
There are a couple of tests now that attempt to stress test the
rename detection code and they are quite slow. Most of the time
is spent setting up the test data on disk and in the index. When
we roll out performance improvements for index insertion, it
should also speed up these tests I hope.

Reorganize diff and add basic diff driver
This is a significant reorganization of the diff code to break it
into a set of more clearly distinct files and to document the new
organization. Hopefully this will make the diff code easier to
understand and to extend.
This adds a new `git_diff_driver` object that looks of diff driver
information from the attributes and the config so that things like
function content in diff headers can be provided. The full driver
spec is not implemented in the commit - this is focused on the
reorganization of the code and putting the driver hooks in place.
This also removes a few #includes from src/repository.h that were
overbroad, but as a result required extra #includes in a variety
of places since including src/repository.h no longer results in
pulling in the whole world.

Fix issues with git_diff_find_similar
There are a number of bugs in the rename code that only were
obvious when I started testing it against large old repos with
more complex patterns. (The code to do that testing is not ready
to merge with libgit2, but I do plan to add more thorough tests.)
This contains a significant number of changes and also tweaks the
public API slightly to make emulating core git easier.
Most notably, this separates the GIT_DIFF_FIND_AND_BREAK_REWRITES
flag into FIND_REWRITES (which adds a self-similarity score to
every modified file) and BREAK_REWRITES (which splits the modified
deltas into add/remove pairs in the diff list). When you do a raw
output of core git, rewrites show up as M090 or such, not at A and
D output, so I wanted to be able to emulate that.
Publicly, this also changes the flags to be uint16_t since we
don't need values out of that range.
Internally, this contains significant changes from a number of
small bug fixes (like using the wrong side of the diff to decide
if the object could be found in the ODB vs the workdir) to larger
issues about which files can and should be compared and how the
various edge cases of similarity scores should be treated.
Honestly, I don't think this is the last update that will have to
be made to this code, but I think this moves us closer to correct
behavior and I tried to document the code so it would be easier
to follow..

Further threading fixes
This builds on the earlier thread safety work to make it so that
setting the odb, index, refdb, or config for a repository is done
in a threadsafe manner with minimized locking time. This is done
by adding a lock to the repository object and using it to guard
the assignment of the above listed pointers. The lock is only
held to assign the pointer value.
This also contains some minor fixes to the other work with pack
files to reduce the time that locks are being held to and fix an
apparently memory leak.

Make tree iterator handle icase equivalence
There is a serious bug in the previous tree iterator implementation.
If case insensitivity resulted in member elements being equivalent
to one another, and those member elements were trees, then the
children of the colliding elements would be processed in sequence
instead of in a single flattened list. This meant that the tree
iterator was not truly acting like a case-insensitive list.
This completely reworks the tree iterator to manage lists with
case insensitive equivalence classes and advance through the items
in a unified manner in a single sorted frame.
It is possible that at a future date we might want to update this
to separate the case insensitive and case sensitive tree iterators
so that the case sensitive one could be a minimal amount of code
and the insensitive one would always know what it needed to do
without checking flags.
But there would be so much shared code between the two, that I'm
not sure it that's a win. For now, this gets what we need.
More tests are needed, though.

Add payload "_r" versions of bsearch and tsort
git__bsearch and git__tsort did not pass a payload through to the

adds git__bsearch_r and git__tsort_r versions that pass a third
parameter to the cmp function of a user payload.

Some diff refactorings to help code reuse
There are some diff functions that are useful in a rewritten
checkout and this lays some groundwork for that. This contains
three main things:
1. Share the function diff uses to calculate the OID for a file
in the working directory (now named `git_diff__oid_for_file`
2. Add a `git_diff__paired_foreach` function to iterator over
two diff lists concurrently. Convert status to use it.
3. Move all the string/prefix/index entry comparisons into
function pointers inside the `git_diff_list` object so they
can be switched between case sensitive and insensitive
versions. This makes them easier to reuse in various
functions without replicating logic. As part of this, move
a couple of index functions out of diff.c and into index.c.

Ranged iterators and rewritten git_status_file
The goal of this work is to rewrite git_status_file to use the
same underlying code as git_status_foreach.
This is done in 3 phases:
1. Extend iterators to allow ranged iteration with start and
end prefixes for the range of file names to be covered.
2. Improve diff so that when there is a pathspec and there is
a common non-wildcard prefix of the pathspec, it will use
ranged iterators to minimize excess iteration.
3. Rewrite git_status_file to call git_status_foreach_ext
with a pathspec that covers just the one file being checked.
Since ranged iterators underlie the status & diff implementation,
this is actually fairly efficient. The workdir iterator does
end up loading the contents of all the directories down to the
single file, which should ideally be avoided, but it is pretty
good.

Includes:

- Rewritten `config_write`, now with 99% less goto-spaghetti
- Error state in `git_filebuf`: filebuf write functions no longer
need to be checked for error returns. If any of the writes performed
on a buffer fail, the last call to `git_filebuf_commit` or
`git_filebuf_hash` will fail accordingly and set the appropiate error
message. Baller!

Remove poor git__removechar function
Going back over this, the git__removechar function was not
needed (only invoked once) and is actually mislabeled. As
implemented, it really only made sense for removing backslash
characters, since two of the "removed" characters in a row
would include the second one -- i.e. it really implements
stripping backslash-escaped strings where a backslash allows
internal whitespace in a word.

Fix handling of relative paths for attrs
Per issue #533, the handling of relative paths in attribute
and ignore files was not right. Fixed this by pre-joining
the relative path of the attribute/ignore file onto the match
string when a full path match is required.
Unfortunately, fixing this required a bit more code than I
would have liked because I had to juggle things around so that
the fnmatch parser would have sufficient information to prepend
the relative path when it was needed.

Improved gitattributes macro implementation
This updates to implementation of gitattribute macros to be much more
similar to core git (albeit not 100%) and to handle expansion of
macros within macros, etc. It also cleans up the refcounting usage
with macros to be much cleaner.
Also, this adds a new vector function `git_vector_insert_sorted()`
which allows you to maintain a sorted list as you go. In order to
write that function, this changes the function `git__bsearch()` to
take a somewhat different set of parameters, although the core
functionality is still the same.

Adds a bunch more tests and fixed some memory leaks. Note that
adding macros required me to use refcounted attribute assignment
definitions, which complicated, but probably improved memory usage.

repository: Change ownership semantics
The ownership semantics have been changed all over the library to be
consistent. There are no more "borrowed" or duplicated references.
Main changes:
- `git_repository_open2` and `3` have been dropped.
- Added setters and getters to hotswap all the repository owned
objects:
`git_repository_index`
`git_repository_set_index`
`git_repository_odb`
`git_repository_set_odb`
`git_repository_config`
`git_repository_set_config`
`git_repository_workdir`
`git_repository_set_workdir`
Now working directories/index files/ODBs and so on can be
hot-swapped after creating a repository and between operations.
- All these objects now have proper ownership semantics with
refcounting: they all require freeing after they are no longer
needed (the repository always keeps its internal reference).
- Repository open and initialization has been updated to keep in
mind the configuration files. Bare repositories are now always
detected, and a default config file is created on init.
- All the tests affected by these changes have been dropped from the
old test suite and ported to the new one.

Remove unused methods
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.

vector: Timsort all of the things
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.

util: introduce merge sort routine
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().

fileops: Cleanup
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.

Add git.git's fnmatch, which is really GNU's and the git__fnmatch wrapper
If the strings match, git__fnmatch returns GIT_SUCCESS and
GIT_ENOMATCH on failure to match.
MSVC fixes: Added a test for _MSC_VER and (in that case) defined
HAVE_STRING_H to 1 so it doesn't try to include <strings.h> which
doesn't exist in the MSVC world. Moved the function declarations to
use the modern inline ones so MSVC doesn't have a fit. Added casts
everywhere so MSVC doesn't crap its pants.

Change error handling mechanism once again
Ok, this is the real deal. Hopefully. Here's how it's going to work:
- One main method, called `git__throw`, that sets the error
code and error message when an error happens.
This method must be called in every single place where an error
code was being returned previously, setting an error message
instead.
Example, instead of:
return GIT_EOBJCORRUPTED;
Use:
return git__throw(GIT_EOBJCORRUPTED,
"The object is missing a finalizing line feed");
And instead of:
[...] {
error = GIT_EOBJCORRUPTED;
goto cleanup;
}
Use:
[...] {
error = git__throw(GIT_EOBJCORRUPTED, "What an error!");
goto cleanup;
}
The **only** exception to this are the allocation methods, which
return NULL on failure but already set the message manually.
/* only place where an error code can be returned directly,
because the error message has already been set by the wrapper */
if (foo == NULL)
return GIT_ENOMEM;
- One secondary method, called `git__rethrow`, which can be used to
fine-grain an error message and build an error stack.
Example, instead of:
if ((error = foobar(baz)) < GIT_SUCCESS)
return error;
You can now do:
if ((error = foobar(baz)) < GIT_SUCCESS)
return git__rethrow(error, "Failed to do a major operation");
The return of the `git_lasterror` method will be a string in the
shape of:
"Failed to do a major operation. (Failed to do an internal
operation)"
E.g.
"Failed to open the index. (Not enough permissions to access
'/path/to/index')."
NOTE: do not abuse this method. Try to write all `git__throw`
messages in a descriptive manner, to avoid having to rethrow them to
clarify their meaning.
This method should only be used in the places where the original
error message set by a subroutine is not specific enough.
It is encouraged to continue using this style as much possible to
enforce error propagation:
if ((error = foobar(baz)) < GIT_SUCCESS)
return error; /* `foobar` has set an error message, and
we are just propagating it */
The error handling revamp will take place in two phases:
- Phase 1: Replace all pieces of code that return direct error codes
with calls to `git__throw`. This can be done semi-automatically
using `ack` to locate all the error codes that must be replaced.
- Phase 2: Add some `git__rethrow` calls in those cases where the
original error messages are not specific enough.
Phase 1 is the main goal. A minor libgit2 release will be shipped once
Phase 1 is ready, and the work will start on gradually improving the
error handling mechanism by refining specific error messages.
OTHER NOTES:
- When writing error messages, please refrain from using weasel
words. They add verbosity to the message without giving any real
information. (<3 Emeric)
E.g.
"The reference file appears to be missing a carriage return"
Nope.
"The reference file is missing a carriage return"
Yes.
- When calling `git__throw`, please try to use more generic error
codes so we can eventually reduce the list of error codes to
something more reasonable. Feel free to add new, more generic error
codes if these are going to replace several of the old ones.
E.g.
return GIT_EREFCORRUPTED;
Can be turned into:
return git__throw(GIT_EOBJCORRUPTED,
"The reference is corrupted");

config: store the section name separately
The section and variable names use different rules, so store them as
two different variables internally.
This will simplify the configuration-writing code as well later on,
but even with parsing, the code is simpler.
Take this opportunity to add a variable to the list directly when
parsing instead of passing through config_set.

I broke your bindings
Hey. Apologies in advance -- I broke your bindings.
This is a major commit that includes a long-overdue redesign of the
whole object-database structure. This is expected to be the last major
external API redesign of the library until the first non-alpha release.
Please get your bindings up to date with these changes. They will be
included in the next minor release. Sorry again!
Major features include:
- Real caching and refcounting on parsed objects
- Real caching and refcounting on objects read from the ODB
- Streaming writes & reads from the ODB
- Single-method writes for all object types
- The external API is now partially thread-safe
The speed increases are significant in all aspects, specially when
reading an object several times from the ODB (revwalking) and when
writing big objects to the ODB.
Here's a full changelog for the external API:
blob.h
------
- Remove `git_blob_new`
- Remove `git_blob_set_rawcontent`
- Remove `git_blob_set_rawcontent_fromfile`
- Rename `git_blob_writefile` -> `git_blob_create_fromfile`
- Change `git_blob_create_fromfile`:
The `path` argument is now relative to the repository's working dir
- Add `git_blob_create_frombuffer`
commit.h
--------
- Remove `git_commit_new`
- Remove `git_commit_add_parent`
- Remove `git_commit_set_message`
