This can be used by tools to show mesages about failing to communicate
with the server. The error message in this case will often contain the
server's error message, as far as it managed to send anything.
These were left over from the culling as it's not clear which use-cases
might benefit from this. It is not clear that we want to support any
use-case which depends on changing the remote's idea of the base
refspecs rather than passing in different per-operation refspec list, so
remove these functions.
The base refspecs changing can be a cause of confusion as to what is the
current base refspec set and complicate saving the remote's
configuration.
Change `git_remote_add_{fetch,push}()` to update the configuration
instead of an instance.
This finally makes `git_remote_save()` a no-op, it will be removed in a
later commit.
While this will rarely be different from the default, having it in the
remote adds yet another setting it has to keep around and can affect its
behaviour. Move it to the options.
Instead of having it set in a different place from every other callback,
put it the main structure. This removes some state from the remote and
makes it behave more like clone, where the constructors are passed via
the options.
As a first step in removing the repository-saving logic, don't allow
chaning the url or push url from a remote object, but change the
configuration on the configuration immediately.
Having the setting be different from calling its actions was not a great
idea and made for the sake of the wrong convenience.
Instead of that, accept either fetch options, push options or the
callbacks when dealing with the remote. The fetch options are currently
only the callbacks, but more options will be moved from setters and
getters on the remote to the options.
This does mean passing the same struct along the different functions but
the typical use-case will only call git_remote_fetch() or
git_remote_push() and so won't notice much difference.
Restricting files to size_t is a silly limitation. The loose backend
writes to a file directly, so there is no issue in using 63 bits for the
size.
We still assume that the header is going to fit in 64 bytes, which does
mean quite a bit smaller files due to the run-length encoding, but it's
still a much larger size than you would want Git to handle.
While we are confident about the size of an int in architectures we're
likely to care about, the index format is defined by the exact size of
the fields. Use the definitions which show the exact width of the entry
fields.
As part of that, bring back 32-bit time and size fields, which currently
are 64 bits wide and can bring a false sense of security in how much
data they really store. Document that these fields are not to be taken
as authoritative.
When checking out with a case-insensitive working directory, we
want to change the case of items in the working directory to
reflect changes that occured in the checkout target. Diff now
has an option to break case-changing renames into delete/add.
In `git_rebase_operation_current()`, indicate when a rebase has not
started (with `GIT_REBASE_NO_OPERATION`) rather than conflating that
with the first operation being in-progress.
It can be useful for the caller to know which update commands will be
sent to the server before the packfile is pushed up. git does this via
the pre-push hook.
We don't have hooks, but as it adds introspection into what is
happening, we can add a callback which performs the same function.
As it seems it's not quite clear what it means to push a commit, try to
be more explicit about adding a new root and that we may not see this
commit if it is hidden.
This function recursively inserts the given object and any referenced
ones. It can be thought of as a more general version of the functions to
insert a commit or tree.
This extra constructor will be useful for the annotated versions of
ref-modifying functions, as it allows us to create a commit with the
extended sha syntax which was used to retrieve it.
We do not always want to put the id directly into the reflog, but we
want to speicfy what a user typed. For this use-case we provide
annotated version of a few functions which let the caller specify what
user-friendly name was used when asking for the operation.
Most use-cases for the object packer communicate in terms of commits
which each side has. We already have an object to specify this
relationship between commits, namely git_revwalk.
By knowing which commits we want to pack and which the other side
already has, we can perform similar optimisations to git, by marking
each tree as interesting or uninteresting only once, and not sending
those trees which we know the other side has.
This changes the get_entry() method to return a refcounted version of
the config entry, which you have to free when you're done.
This allows us to avoid freeing the memory in which the entry is stored
on a refresh, which may happen at any time for a live config.
For this reason, get_string() has been forbidden on live configs and a
new function get_string_buf() has been added, which stores the string in
a git_buf which the user then owns.
The functions which parse the string value takea advantage of the
borrowing to parse safely and then release the entry.
We want to use the "checkout: moving from ..." message in order to let
git know when a change of branch has happened. Make the convenience
functions for this goal write this message.
This namespace is about behaving like git's branch command, so let's do
exactly that instead of taking a reflog message.
This override is still available via the reference namespace.
The signature for the reflog is not something which changes
dynamically. Almost all uses will be NULL, since we want for the
repository's default identity to be used, making it noise.
In order to allow for changing the identity, we instead provide
git_repository_set_ident() and git_repository_ident() which allow a user
to override the choice of signature.
Win32 DLLs have four fields for the version number (major, minor,
teeny, patch). If a consumer wants to build a custom DLL, it may
be useful to set the patchlevel version number in the DLL.
This value only affects the DLL version number, it does not affect
the resultant "version number", which remains major.minor.teeny.
git_index_add_frombuffer enables now to store a memory buffer in the odb
and to store an entry in the index directly if the index is attached to a
repository.
Add structures and preliminary functions to take a buffer, file or
blob and write the contents in chunks through an arbitrary number
of chained filters, finally writing into a user-provided function
accept the contents.
On case insensitive filesystems, we may have files in the working
directory that case fold to a name we want to write. Remove those
files (by default) so that we will not end up with a filename that
has the unexpected case.
The implementation of the hashsig API disallows computing a signature on
small files containing only a few lines. This new flag disables this
behavior.
git_diff_find_similar() sets this flag by default which means that rename
/ copy detection of small files will now work. This in turn affects the
behavior of the git_status and git_blame APIs which will now detect rename
of small files assuming the right options are passed.
`git_merge_commits` (and thus `git_merge`) do not use the same
strategy as `git-merge-recursive` wherein they can produce an
artificial common ancestor that is the merge of all common
ancestors. Document this accordingly.
For the REUC and NAME entries, we use size_t internally, and we take
size_t for the get_byindex() functions, but the entrycount() functions
strangely cast to an unsigned int instead.
