While we do verify that we are able to open the global ".gitconfig" file
in config::global::open_global, we never verify that we it is in fact
readable. Do so by writing the global configuration file and verifying
that reading from it produces the expected values.

We've got reports that users are unable to open repos when their global
configuration ("~/.gitconfig") is a symlink. Add a test to verify that
we are in fact able to do so as expected.

The config::global test suite creates various different directories and
files which are being populated with pretend-global files.
Unfortunately, the tests do not clean up after themselves, which may
cause subsequent tests to fail due to cruft left behind.
Fix this by always removing created directories and their contents.

Matching on the prefix of a negated pattern was triggering false
negatives on siblings of that pattern. e.g.
Given the .gitignore:
dir/*
!dir/sub1/sub2/**
The path `dir/a.text` would not be ignored.

When a directory's contents are ignored, and then a glob negation is made to a nested subdir, other subdirectories are now unignored

Currently, our headers need to leak some implementation details of maps due to
their direct use of indices in the implementation of their foreach macros. This
makes it impossible to completely hide the map structures away, and also makes
it impossible to include the khash implementation header in the C files of the
respective map only.
This is now being fixed by providing a high-level iteration interface
`map_iterate`, which takes as inputs the map that shall be iterated over, an
iterator as well as the locations where keys and values shall be put into. For
simplicity's sake, the iterator is a simple `size_t` that shall initialized to
`0` on the first call. All existing foreach macros are then adjusted to make use
of this new function.

Currently, one would use either `git_oidmap_insert` to insert key/value pairs
into a map or `git_oidmap_put` to insert a key only. These function have
historically been macros, which is why their syntax is kind of weird: instead of
returning an error code directly, they instead have to be passed a pointer to
where the return value shall be stored. This does not match libgit2's common
idiom of directly returning error codes.Furthermore, `git_oidmap_put` is tightly
coupled with implementation details of the map as it exposes the index of
inserted entries.
Introduce a new function `git_oidmap_set`, which takes as parameters the map,
key and value and directly returns an error code. Convert all trivial callers of
`git_oidmap_insert` and `git_oidmap_put` to make use of it.

The current way of looking up an entry from a map is tightly coupled with the
map implementation, as one first has to look up the index of the key and then
retrieve the associated value by using the index. As a caller, you usually do
not care about any indices at all, though, so this is more complicated than
really necessary. Furthermore, it invites for errors to happen if the correct
error checking sequence is not being followed.
Introduce a new high-level function `git_oidmap_get` that takes a map and a key
and returns a pointer to the associated value if such a key exists. Otherwise,
a `NULL` pointer is returned. Adjust all callers that can trivially be
converted.

There currently exist two different function names for getting the entry count
of maps, where offmaps offset and string maps use `num_entries` and OID maps use
`size`. In most programming languages with built-in map types, this is simply
called `size`, which is also shorter to type. Thus, this commit renames the
other two functions `num_entries` to match the common way and adjusts all
callers.

Currently, the lifecycle functions for maps (allocation, deallocation, resize)
are not named in a uniform way and do not have a uniform function signature.
Rename the functions to fix that, and stick to libgit2's naming scheme of saying
`git_foo_new`. This results in the following new interface for allocation:
- `int git_<t>map_new(git_<t>map **out)` to allocate a new map, returning an
error code if we ran out of memory
- `void git_<t>map_free(git_<t>map *map)` to free a map
- `void git_<t>map_clear(git<t>map *map)` to remove all entries from a map
This commit also fixes all existing callers.

Previously, we would fail to correctly truncate the source buffer
if the source has more than one line and ends with a non-newline
character. In the following call, we thus truncate the source
string in the middle of the second line. Without the bug fixed,
we would successfully apply the patch to the source and return
success. With the overflow being fixed, we should return an
error now.

Enable creation of worktree from bare repo's default branch

In a bare repository, HEAD usually points to the branch that is
considered the "default" branch. As the current implementation for
`git_branch_is_checked_out` only does a comparison of HEAD with the
branch that is to be checked, it will say that the branch pointed to by
HEAD in such a bare repo is checked out.
Fix this by skipping the main repo's HEAD when it is bare.
|
| | | |
| | |
| | |
| | |
| | |
| | |
| | | |
Right now, the function `git_repository_foreach_head` will always
iterate over all HEADs of the main repository and its worktrees. In some
cases, it might be required to skip either of those, though. Add a flag
in preparation for the following commit that enables this behaviour.

Libraries should use assert(3P) only very scarcely. First, we usually
shouldn't cause the caller of our library to abort in case where the
assert fails. Second, if code is compiled with -DNDEBUG, then the assert
will not be included at all.
In our `git_branch_is_checked_out` function, we have an assert that
verifies that the given reference parameter is non-NULL and in fact a
branch. While the first check is fine, the second is not. E.g. when
compiled with -DNDEBUG, we'd proceed and treat the given reference as a
branch in all cases.
Fix the issue by instead treating a non-branch reference as not being
checked out. This is the obvious solution, as references other than
branches cannot be directly checked out.

We currently do not have any tests at all for the

Although the error functions were deprecated, we did not properly mark
them as deprecated. We need to include the `deprecated.h` file in order
to ensure that the functions get their export attributes.
Similarly, do not define `GIT_DEPRECATE_HARD` within the library, or
those functions will also not get their export attributes. Define that
only on the tests and examples.

index: preserve extension parsing errors
|
| | |
| |
| |
| |
| |
| |

Previously, we would clobber any extension-specific error message with
an "extension is truncated" message. This makes `read_extension`
correctly preserve those errors, takes responsibility for truncation
errors, and adds a new message with the actual extension signature for
unsupported mandatory extensions.

Move the deprecated stream tests into their own compilation unit. This
will allow us to disable any preprocessor directives that apply to
