This ports over some of the tests from
https://github.com/libgit2/libgit2/pull/1683
by @yorah and @ethomson
|
|
This makes the git_buf struct that was used internally into an
externally available structure and eliminates the git_buffer.
As part of that, some of the special cases that arose with the
externally used git_buffer were blended into the git_buf, such as
being careful about git_buf objects that may have a NULL ptr and
allowing for bufs with a valid ptr and size but zero asize as a
way of referring to externally owned data.
|
|
This adds the ident filter (that knows how to replace $Id$) and
tweaks the filter APIs and code so that git_filter_source objects
actually have the updated OID of the object being filtered when
it is a known value.
|
|
This moves the git_filter_list into the public API so that users
can create, apply, and dispose of filter lists. This allows more
granular application of filters to user data outside of libgit2
internals.
This also converts all the internal usage of filters to the public
APIs along with a few small tweaks to make it easier to use the
public git_buffer stuff alongside the internal git_buf.
|
|
This creates include/sys/filter.h with a basic definition of a
git_filter and then converts the internal code to use it. There
are related internal objects (git_filter_list) that we will want
to publish at some point, but this is a first step.
|
|
This tests the fixes for issues from #1849
|
|
Now that #1785 is merged, git_odb_stream_finalize_write() calculates the object id before invoking the odb backend.
This commit gives a chance to the backend to check if it already knows this object.
|
|
|
|
This is in preparation for moving the hashing to the frontend, which
requires us to handle the incoming data before passing it to the
backend's stream.

Even more rename detection fixes
|
|
|
|
This flips rename detection around so instead of creating a
forward mapping from deltas to possible rename targets, instead
it creates a reverse mapping, looking at possible targets and
trying to find a source that they could have been renamed or
copied from. This is important because each output can only
have a single source, but a given source could map to multiple
outputs (in the form of COPIED records).
Additionally, this makes a couple of tweaks to the public rename
detection APIs, mostly renaming a couple of options that control
the behavior to make more sense and to be more like core Git.
I walked through the tests looking at the exact results and
updated the expectations based on what I saw. The new code is
different from the old because it cannot give some nonsense
results (like A was renamed to both B and C) which were part of
the outputs previously.

I frequently want to the the first N digits of an OID formatted
as a string and I'd like it to be efficient. This function makes
that easy and I could rewrite the OID formatters in terms of it.

Make sure error messages are set for most error returns
|
|
Peeling to an invalid type is now checked via an assert so this
test is no longer relevant.

We need to hammer the packfile open phase harder in the thread
tests, in addition to the cache API.
|
|
|
|
|
|
The indexer was creating a packfile object separately from the
code in pack.c which was a problem since I put a call to
git_mutex_init into just pack.c. This commit updates the pack
function for creating a new pack object (i.e. git_packfile_check())
so that it can be used in both places and then makes indexer.c
use the shared initialization routine.
There are also a few minor formatting and warning message fixes.
|
|
This adds some basic tests for the oidmap just to make sure that
collisions, etc. are dealt with correctly.
This also adds some tests for the new caching that check if items
are inserted (or not inserted) properly into the cache, and that
the cache can hold up in a multithreaded environment without error.

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 adds crlf/lf conversion functions into buf_text with more
efficient implementations that bypass the high level buffer
functions. They attempt to minimize the number of reallocations
done and they directly write the buffer data as needed if they
know that there is enough memory allocated to memcpy data.
Tests are added for these new functions. The crlf.c code is
updated to use the new functions.
Removed the include of buf_text.h from filter.h and just include
it more narrowly in the places that need it.

This reverts commit efe7fad6c96a3d6197a218aeaa561ec676794499, except for
the indentation fixes.
|
|
Along with that, fix indentation in tests-clar/object/raw/hash.c
|
|
The recent changes with git_treebuilder_entrycount point out that
the test coverage for git_treebuilder_remove and
git_treebuilder_entrycount is completely absent. This adds tests.

as per @vmg's request

Also ammends one of the tag tests to make sure it's working.

Previously a NULL oid was handled like an empty buffer and
returned a status empty string. This makes git_oid_tostr()
set the output buffer to the empty string instead.

There are many different broken filemodes in the wild so we need to
protect against them and give something useful up the chain. Don't
fail when reading a tree from the ODB but normalize the mode as best
we can.
As 664 is no longer a mode that we consider to be valid and gets
normalized to 644, we can stop accepting it in the treebuilder. The
library won't expose it to the user, so any invalid modes are a bug.

There are many scattered functions that look into the contents of
buffers to do various text manipulations (such as escaping or
unescaping data, calculating text stats, guessing if content is
binary, etc). This groups all those functions together into a
new file and converts the code to use that.
This has two enhancements to existing functionality. The old
text stats function is significantly rewritten and the BOM
detection code was extended (although largely we can't deal with
anything other than a UTF8 BOM).
