pkh put only spoke SFTP to the PPA queue, so a failure of the SSH
transport itself (TCP, banner exchange) failed the upload even though
dput happily pushes the same files: its plain ppa: profile goes over
the anonymous FTP queue of ppa.launchpad.net, the same destination
over another port.
Classify the SSH connection failures: Transport (the connection never
came up: resolution, TCP, banner or key exchange) degrades to that FTP
queue — the upload order (payload first, .changes last), the
reverse-order DELE cleanup of a failed upload and the per-chunk
progress reporting all mirror the SFTP path, sharing cleanup_list.
Refused failures (host key not accepted, no matching authentication)
stay errors: silently switching transport would bypass the refusal.
The FTP client is suppaftp's blocking stream, with the time bounds it
does not carry by itself: the control channel's reads and writes, the
data channel's writes and connect (through a custom passive stream
builder), and the NAT workaround for PASV replies announcing an
unroutable address. The queue endpoints (host, port) join
data/launchpad.yml next to the SFTP ones, and the FTP transport is
covered by unit tests against an in-process fake queue plus a live
control-channel handshake with the real server (ignored, network).
put() loses its MultiProgress parameter: the summary, pre-flight and
connection spinners become view messages, the per-file SFTP transfer
reports determinate progress through view.progress (upload_file takes
a byte-count callback instead of an indicatif bar), and the display is
released through view.suspend on every exit path. The hardcoded
trust-on-first-use prompt in the SSH host-key verification becomes the
Prompter::accept_host_key port (fail-closed by default; the terminal
prompter prints the authenticity banner and confirms), so a remote
frontend can surface its own host-key dialog.
A failed or interrupted upload left the already-uploaded payloads — or
a truncated .changes — in the PPA's incoming area. On failure the
already-uploaded files are now removed best-effort in reverse upload
order with the failed file first, so a .changes never outlives the
payloads it references; the original upload error keeps precedence over
cleanup failures, and record-after-success semantics are unchanged (a
failed upload must not count as uploaded).
An unreadable or unparsable known_hosts file was swallowed with
'let _', silently downgrading to prompt-and-accept without telling the
user why their configuration was ignored: warn naming the file, then
continue. And when the pinned Launchpad fingerprint matches, a
DIFFERENT key recorded for that host in known_hosts was silently
bypassed: warn about the stale entry (diagnostic only — the published
fingerprint stays authoritative).
TcpStream::connect and the blocking libssh2 session had no timeouts: a
black-holed host hung pkh put forever, mid-resolution, mid-handshake or
mid-upload. Connect attempts now get a 15 s timeout per resolved
address, the session gets a 30 s API timeout for the handshake/auth
phase and a 300 s per-call timeout for SFTP operations (per low-level
libssh2 call, not per transfer — documented); failures name the
operation and host.
Host pattern lists were evaluated per-pattern with 'any', so
'Host * !*.launchpad.net' matched ppa.launchpad.net via the wildcard;
a block now applies only if a positive pattern matches and no negated
one does (OpenSSH's rule). The system ssh_config was read first with
first-obtained-wins, inverting OpenSSH's user-over-system precedence;
the user file is read first now. A Match block also no longer leaks
the previous Host block's match state (its options are ignored until
the next Host).
ssh2::File's Drop discards the close-handshake error ('too late to
recover'), so a quota or server-side abort surfacing in the final ACKs
was recorded as a successful upload of a truncated file. Close upload
handles explicitly and propagate the error; also applies to the ssh
context driver's write_file and upload_recursive, which had the same
silent-drop issue.
IdentityFile values were stored verbatim, so the near-universal
'IdentityFile ~/.ssh/key' spelling never matched an existing file and
the key was silently skipped during authentication. Expand a leading
~ (only that form; ~user and embedded tildes stay verbatim) against
the user's home directory when parsing.
Upload built source packages over SFTP with host-key verification
(Launchpad fingerprints pinned in host_keys.yml, ask-to-accept
otherwise), Launchpad account discovery (git config lp.user), and
pre-flight checks the upload queue itself never does: changes file
discovery/validation, PPA existence via the Launchpad API, target
series validity, and debian/control Section validity (sections
bundled in distro_info.yml). Upload log prevents duplicate uploads
unless --force.
