When we moved from acting on the instance to acting on the
configuration, we dropped the validation of the passed refspec, which
can lead to writing an invalid refspec to the configuration. Bring that
validation back.
The public key field is optional and as such can take NULL. Account for
that and do not call strlen() on NULL values. Also assert() for non-NULL
values of username & private key.
Declare GIT_CREDTYPE_SSH_MEMORY to have consistent API independently of
whether libgit2 was built with or without in-memory key passing support.
Or rather, to have it at all since build-time definitions are not stored
in headers.
Make both username & password in git_cred_userpass_payload 'const'.
The values are not altered anywhere, and the extra qualifier allows
clients to assign 'const' values there.
When we look for which remote corresponds to a remote-tracking branch,
we look in the refspecs to see which ones matches. If none do, we should
abort. We currently ignore the error message from this operation, so
let's not do that anymore.
As part of the test we're writing, let's test for the expected behaviour
if we cannot find a refspec which tells us what the remote-tracking
branch for a remote would look like.
When we find out that we're dealing with a matching refspec, we set the
flag and return immediately. This leaves the strings as NULL, which
breaks the contract.
Assign these pointers to a string with the correct values.
When we discover that we want to keep a negative rule, make sure to
clear the error variable, as it we otherwise return whatever was left by
the previous loop iteration.
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.
When we fail to read from stdout, it's typically because the URL was
wrong and the server process has sent some output over its stderr
output.
Read that output and set the error message to whatever we read from it.
We set an error if we get an error when reading, but we don't bother
setting an error message for write failing. This causes a cryptic error
to be shown to the user when the target filesystem is full.
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 code used to rely on the clone code calling the remote's save, which
does not happen anymore, meaning that the configuration settings the
remote expected were not being written to disk.
The run-time configuration was still being affected, so the right branch
was being cloned. The tests continued to pass as we did not check for
the configuration entires. Fix this by creating the remote with the
single-branch refspec we want and checking for its existence in the
configuration.
This function deals with functions doing IO which means the amount of
errors that can happen is quit large. It does not help if it always
ovewrites the underlying error message with a less understandable
version of "something went wrong".
Instead, only use this generic message if there was no error set by the
callback.
