We currently have gitno for talking over TCP, but this needs to know
about both plaintext and OpenSSL connections and the code has gotten
somewhat messy with ifdefs determining which version of the function
should be called.
In order to clean this up and abstract away the details of sending over
the different types of streams, we can instead use an interface and
stack stream implementations.
We may not be able to use the stackability with all streams, but we
are definitely be able to use the abstraction which is currently spread
between different bits of gitno.
This makes them show up in the reference, even if the text itself isn't
the most descriptive.
These have been found with
grep -Przon '\n\ntypedef struct.*?\{' -- include
grep -Przon '\n\ntypedef enum.*?\{' -- include
There are some combination of objects and target types which we know
cannot be fulfilled. Return EINVALIDSPEC for those to signify that there
is a mismatch in the user-provided data and what the object model is
capable of satisfying.
If we start at a tag and in the course of peeling find out that we
cannot reach a particular type, we return EPEEL.
This function, similar in style to git_remote_fetch(), performs all the
steps required for a push, with a similar interface.
The remote callbacks struct has learnt about the push callbacks, letting
us set the callbacks a single time instead of setting some in the remote
and some in the push operation.
This describes their purpose better, as we now initialize ssl and some
other global stuff in there. Calling the init function is not something
which has been optional for a while now.
This function has one output but can match multiple files, which can be
unexpected for the user, which would usually path the exact path of the
file he wants the status of.
Already cherry-picked commits should not be re-included. If all changes
included in a commit exist in the upstream, then we should error with
GIT_EAPPLIED.
`git_rebase_next` will apply the next patch (or cherry-pick)
operation, leaving the results checked out in the index / working
directory so that consumers can resolve any conflicts, as appropriate.
Remote objects are not meant to be changed from under the user. We did
this in rename, but only the name and left the refspecs, such that a
save would save the wrong refspecs (and a fetch and anything else would
use the wrong refspecs).
Instead, let's simply take a name and not change any loaded remote from
under the user.
This function does not in fact tell us anything, as almost anything with
a colon in it is a valid rsync-style SSH path; it can not tell us that
we do not support ftp or afp or similar as those are still valid SSH
paths and we do support that.
We don't need the remote loaded, and the function extracted both of
these from the git_remote in order to do its work, so let's remote a
step and not ask for the loaded remote at all.
This fixes#2390.
A transaction allows you to lock multiple references and set up changes
for them before applying the changes all at once (or as close as the
backend supports).
This can be used for replication purposes, or for making sure some
operations run when the reference is locked and thus cannot be changed.
With opportunistic ref updates, git has introduced the concept of having
base refspecs *and* refspecs that are active for a particular fetch.
Let's start by letting the user override the refspecs for download.
When we describe the workdir, we perform a describe on HEAD and then
check to see if the worktree is dirty. If it is and we have a suffix
string, we append that to the buffer.
Instead of printing out to the buffer inside the information-gathering
phase, write the data to a intermediate result structure.
This allows us to split the options into gathering options and
formatting options, simplifying the gathering code.
Instead of spreading the data in function arguments, some of which
aren't used for ssh and having a struct only for ssh, use a struct for
both, using a common parent to pass to the callback.
This option make it easy to ignore anything about the server we're
connecting to, which is bad security practice. This was necessary as we
didn't use to expose detailed information about the certificate, but now
that we do, we should get rid of this.
If the user wants to ignore everything, they can still provide a
callback which ignores all the information passed.
We should let the user decide whether to cancel the connection or not
regardless of whether our checks have decided that the certificate is
fine. We provide our own assessment to the callback to let the user fall
back to our checks if they so desire.
If the certificate validation fails (or always in the case of ssh),
let the user decide whether to allow the connection.
The data structure passed to the user is the native certificate
information from the underlying implementation, namely OpenSSL or
WinHTTP.
When using a bare repo with an index, libgit2 attempts to read
files from the index. It caches those files based on the path
to the file, specifically the path to the directory that contains
the file.
If there is no working directory, we use `git_path_dirname_r` to
get the path to the containing directory. However, for the
`.gitattributes` file in the root of the repository, this ends up
normalizing the containing path to `"."` instead of the empty
string and the lookup the `.gitattributes` data fails.
This adds a test of attribute lookups on bare repos and also
fixes the problem by simply rewriting `"."` to be `""`.
Teach git_repository_init_ext to use relative paths for the gitlink
to the work directory. This is used when creating a sub repository
where the sub repository resides in the parent repository's
.git directory.
It does the same as git_remote_supported_url() but has a name which
implies we'd check the URL for correctness while we're simply looking at
the scheme and looking it up in our lists.
While here, fix up the tests so we check all the combination of what's
supported.
The old `allocfmt` is of no use to callers, as they are not able to free
the returned buffer. Export a new API that returns a static string that
doesn't need to be freed.
* Move the transport registration mechanisms into a new header under
'sys/' because this is advanced stuff.
* Remove the 'priority' argument from the registration as it adds
unnecessary complexity. (Since transports cannot decline to operate,
only the highest priority transport is ever executed.) Users who
require per-priority transports can implement that in their custom
transport themselves.
* Simplify registration further by taking a scheme (eg "http") instead
of a prefix (eg "http://").
