This adds tests for diffs with submodules in them and (perhaps
unsurprisingly) requires further fixes to be made. Specifically,
this fixes:
- when considering if a submodule is dirty in the workdir, it was
being treated as dirty even if only the index was dirty.
- git_diff_patch_to_str (and git_diff_patch_print) were "printing"
the headers for files (and submodules) that were unmodified or
had no meaningful content.
- added comment to previous fix and removed unneeded parens.
The purported command output was already inaccurate, as the refs
aren't where it shows. In any event, the labels a reader of this
file really needs are the indices used in commit_sorting_*, to make
it possible to understand them by referring directly from those
arrays to the diagram rather than from the index arrays, to commit_ids,
to the diagram. Add those.

Return the size we'd need to write to instead of simply an
error. Split the function into two to be used later by the upstream
configuration functions.
This started out trying to look at the problems from issue #1425
and gradually grew to a broader set of fixes. There are two core
things fixed here:
1. When you had an ignore like "/bin" which is rooted at the top
of your tree, instead of immediately adding the "bin/" entry
as an ignored item in the diff, we were returning all of the
direct descendants of the directory as ignored items. This
changes things to immediately ignore the directory. Note that
this effects the behavior in test_status_ignore__subdirectories
so that we no longer exactly match core gits ignore behavior,
but the new behavior probably makes more sense (i.e. we now
will include an ignored directory inside an untracked directory
that we previously would have left off).
2. When a submodule only contained working directory changes, the
diff code was always considering it unmodified which was just
an outright bug. The HEAD SHA of the submodule matches the SHA
in the parent repo index, and since the SHAs matches, the diff
code was overwriting the actual status with UNMODIFIED.
These fixes broke existing tests test_diff_workdir__submodules and
test_status_ignore__subdirectories but looking it over, I actually
think the new results are correct and the old results were wrong.
@nulltoken had actually commented on the subdirectory ignore issue
previously.
I also included in the tests some debugging versions of the
shared iteration callback routines that print status or diff
information. These aren't used actively in the tests, but can be
quickly swapped in to test code to give a better picture of what
is being scanned in some of the complex test scenarios.
This option has been sitting unimplemented for a while, so I
finally went through and implemented it along with some tests.
As part of this, I improved the implementation of
GIT_DIFF_IGNORE_SUBMODULES so it be more diligent about avoiding
extra work and about leaving off delta records for submodules to
the greatest extent possible (though it may include them still
if you are request TYPECHANGE records).
This implements working versions of GIT_DIFF_RECURSE_IGNORED_DIRS
and GIT_STATUS_OPT_RECURSE_IGNORED_DIRS along with some tests for
the newly available behaviors. This is not turned on by default
for status, but can be accessed via the options to the extended
version of the command.
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 fixes of the file contents checks in checkout to give
slightly better error messages by directly calling the underlying
clar assertions so the file and line number of the top level call
can be reported correctly, and renames the helpers to not start
with "test_" since that is kind of reserved by clar.
This also enables some of the CRLF tests on all platforms that
were previously Windows only (by pushing a check of the native
line endings into the test body).
This fixes some places where the new tests were leaving the test
area in a bad state or were freeing data they should not free.
It also removes code that is extraneous to the core issue and
fixes an invalid SHA being looked up in one of the tests (which
was failing, but for the wrong reason).
Currently, the odb cache has a fixed size of 128 slots as defined by
GIT_DEFAULT_CACHE_SIZE. Allow users to set the size of the cache via
git_libgit2_opts().
Fixes#1035.
This adds a helper function for the cases where you want to
quickly set a single boolean config value for a repository.
This allowed me to remove a lot of code.
This makes the size_t comparison test nicer (assuming that the
values are actually not using the full length), and converts
some cases that were using it for pointer comparison to use the
macro that is designed for pointer comparison.
1. Fix sort order problem with submodules where "mod" was sorting
after "mod-plus" because they were being sorted as "mod/" and
"mod-plus/". This involved pushing the "contains a .git entry"
test significantly lower in the stack.
2. Reinstate behavior that a directory which contains a .git entry
will be treated as a submodule during iteration even if it is
not yet added to the .gitmodules.
3. Now that any directory containing .git is reported as submodule,
we have to be more careful checking for GIT_EEXISTS when we
do a submodule lookup, because that is the error code that is
returned by git_submodule_lookup when you try to look up a
directory containing .git that has no record in gitmodules or
the index.
This switches the APIs for setting and getting the global/system
search paths from using git_strarray to using a simple string with
GIT_PATH_LIST_SEPARATOR delimited paths, just as the environment
PATH variable would contain. This makes it simpler to get and set
the value.
I also added code to expand "$PATH" when setting a new value to
embed the old value of the path. This means that I no longer
require separate actions to PREPEND to the value.
The goal of this work is to expose the search logic for "global",
"system", and "xdg" files through the git_libgit2_opts() interface.
Behind the scenes, I changed the logic for finding files to have a
notion of a git_strarray that represents a search path and to store
a separate search path for each of the three tiers of config file.
For each tier, I implemented a function to initialize it to default
values (generally based on environment variables), and then general
interfaces to get it, set it, reset it, and prepend new directories
to it.
Next, I exposed these interfaces through the git_libgit2_opts
interface, reusing the GIT_CONFIG_LEVEL_SYSTEM, etc., constants
for the user to control which search path they were modifying.
There are alternative designs for the opts interface / argument
ordering, so I'm putting this phase out for discussion.
Additionally, I ended up doing a little bit of clean up regarding
attr.h and attr_file.h, adding a new attrcache.h so the other two
files wouldn't have to be included in so many places.
This fixes a number of issues identified by valgrind - mostly
missed free calls. Inside valgrind, mmap() may fail which causes
some of the diff tests to fail. This adds a fallback code path
to diff_output.c:get_workdir_content() where is the mmap() fails
the code will now try to read the file data directly into allocated
memory (which is what it would do if the data needed to be filtered
anyhow).
This updates the tree iterator internals to be more efficient.
The tree_iterator_entry objects are now kept as pointers that are
allocated from a git_pool, so that we may use git__tsort_r for
sorting (which is better than qsort, given that the tree is
likely mostly ordered already).
Those tree_iterator_entry objects now keep direct pointers to the
data they refer to instead of keeping indirect index values. This
simplifies a lot of the data structure traversal code.
This also adds bsearch to find the start item position for range-
limited tree iterators, and is more explicit about using
git_path_cmp instead of reimplementing it. The git_path_cmp
changed a bit to make it easier for tree_iterators to use it (but
it was barely being used previously, so not a big deal).
This adds a git_pool_free_array function that efficiently frees a
list of pool allocated pointers (which the tree_iterator keeps).
Also, added new tests for the git_pool free list functionality
that was not previously being tested (or used).
This fixes two bugs with the workdir iterator depth check: first
that the depth was not being decremented and second that empty
directories were counting against the depth even though a frame
was not being created for them.
This also fixes a bug with the ENOTFOUND return code for workdir
iterators when you attempt to advance_into an empty directory.
Actually, that works correctly, but it was incorrectly being
propogated into regular advance() calls in some circumstances.
Added new tests for the above that create a huge hierarchy on
the fly and try using the workdir iterator to traverse it.
Given a group of case-insensitively equivalent tree iterator
entries, this ensures that the case-sensitively first trees will
be used as the representative items. I.e. if you have conflicting
entries "A/B/x", "a/b/x", and "A/b/x", this change ensures that
the earliest entry "A/B/x" will be returned. The actual choice
is not that important, but it is nice to have it stable and to
have it been either the first or last item, as opposed to a
random item from within the equivalent span.
Tree iterator advance was moving forward without taking the
filemode of the entries into account, equating "a" and "a/".
This makes the tree entry comparison code more easily reusable
and fixes the problem.
This fixes an off by one error for generating full paths for
tree entries in tree iterators when INCLUDE_TREES is set. Also,
contains a bunch of small code cleanups with a couple of small
utility functions and macro changes to eliminate redundant code.
If there are case-ambiguities in the path of a case insensitive
tree iterator, it will now rewrite the entire path when it gives
the path name to an entry, so a tree with "A/b/C/d.txt" and
"a/B/c/E.txt" will give the true full paths (instead of case-
folding them both to "A/B/C/d.txt" or "a/b/c/E.txt" or something
like that.
