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).
This adds a check to the drop_crlf filter path to check it the
file in the index already has a CR in it, in which case this will
not drop the CRs from the workdir file contents.
This uncovered a "bug" in `git_blob_create_fromworkdir` where the
full path to the file was passed to look up the attributes instead
of the relative path from the working directory root. This meant
that the check in the index for a pre-existing entry of the same
name was failing.
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.
Implicit type conversion argument of function to size_t type
Suspicious sequence of types castings: size_t -> int -> size_t
Consider reviewing the expression of the 'A = B == C' kind. The expression is calculated as following: 'A = (B == C)'
Unsigned type is never < 0
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 adds a git_pool_freelist_item struct that makes it a little
easier to follow what's going on with the pool free list block
management code. It is functionally neutral.
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.
