We need to enforce additional restrictions on reference names specified in gotsys.conf in order to prevent escaping to arbitrary gotd.conf syntax. Add test coverage.

This directive will not be implemented in the final design. Instead we will be adding authentication to gotwebd with associated config syntax.

SMTP relays for email notifications will only be configured server-side.

While we must install staged blob contents during revert if there are staged changes, the base blob ID recorded in the file index must always reflect the actual base blob from the base commit. Setting the base blob ID to that of a staged blob causes problems. The staged blob's ID is tracked in a separate field. ok op@

Use a dedicated flag to keep track of HEAD ref creation state, rather than checking pe == NULL.

Avoids the need to use got clone -b to get anything at all from a server implementation which does not advertise a HEAD symref. Patch by martijn@

When a reference update sends an empty pack file because the objects already exist on a different branch, gotd was wrongly rejecting the reference update. The logic which protects references from moving kicked in, but didn't account for this particular case. Run a YCA check to ensure the client is only appending new commits to the branch and allow the ref update to proceed if so. Add test coverage. Problem reported by martijn@

Because copy_ref_delta() was forgetting to update the *outsize output parameter, when clients sent ref-deltas gotd was miscalculating the on-disk size of the pack file and would report "bad offset in pack file" if an object was stored at an offset beyond the miscalculated smaller size.

Fixes regress failures due to 'git gc' complaining, as of 2.50.0: '# pack-refs with:' does not start with '# pack-refs with: ' reported by naddy@ ok op@

Could be triggered by running 'got fetch' with a "send" block in got.conf. The functions free_fetch_config() and free_send_config() were freeing data via the global "remote" variable instead of their own argument as intended. Patch by Renato Aguiar

This feature can be used by server administrators to override or augment access permissions set in gotsys.conf if needed.

Deny rules in gotsys.conf didn't actually work until recently and were lacking test coverage.

This can be observed during 'got send' or 'gotadmin pack/cleanup' in some cases. We would keep processing the same parent commits over and over.

Deny rules do not contain the rw/ro authorization mode string. Do not fail if that string is missing. Corresponding tests will be added soon.
