v1.4.7

Compare Source

sync: tar

A new way to share the workspace, available on every architecture: the
tree is streamed in as a ustar archive over the ssh connection the
action already opens, and streamed back the same way when the run
finishes. Nothing is installed in the guest and no filesystem support
is needed on either side, unlike sshfs and nfs. openbsd-builder v2.1.0
declares it for every release, and it was verified on this guest before
the declaration went in: 300 files plus a 1 MB binary blob pushed, a
file written inside the VM, the whole tree pulled back and compared by
content hash.

rsync remains the default.

Under the hood

openbsd-builder v2.1.0 is also the first openbsd build to publish
releases.json, the machine-readable index this action bakes its
configuration from -- which is why the pre-tar method list survived
until now.

The runtime moves to anyvm v0.6.5, ten releases on from the v0.5.5 that
v1.4.6 shipped. Two of its fixes reach every job: a failed folder sync
is now fatal instead of a warning that left the guest running without
the files it was about to use, and the workspace push no longer carries
the runner's own harness directories into the guest.
