put: run the section pre-flight against the uploaded tree

The Section check always read debian/control from the current working directory, so 'pkh put --changes ../other/pkg_changes' validated the wrong tree. With an explicit --changes the check now runs against that file's own directory when it holds debian/control, and is skipped with a warning otherwise; tree uploads are unchanged.
put: remove partial uploads when the transfer fails

vhaudiquet	c1f8893576	put: run the section pre-flight against the uploaded tree CI / build (push) Failing after 2m57s Details CI / test (push) Skipped Details CI / snap (push) Skipped Details The Section check always read debian/control from the current working directory, so 'pkh put --changes ../other/pkg_changes' validated the wrong tree. With an explicit --changes the check now runs against that file's own directory when it holds debian/control, and is skipped with a warning otherwise; tree uploads are unchanged.	2026-09-18 10:40:48 +02:00
vhaudiquet	e640b153bd	put: remove partial uploads when the transfer fails 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).	2026-09-18 10:36:01 +02:00
vhaudiquet	231c478d0b	put: surface known_hosts problems instead of silently degrading 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).	2026-09-18 10:28:34 +02:00

vhaudiquet	b20acf3199	put: bound the SSH connect and session operations with timeouts 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.	2026-09-18 02:03:20 +02:00
vhaudiquet	3feca504fc	put: back up a corrupt uploads.json and write it atomically A corrupt upload log was silently treated as 'never uploaded', disabling the duplicate-upload guard without a diagnostic, and record_upload truncated the file in place — a crash mid-write produced exactly that corrupt state. Parse failures now log an error, back the file up to uploads.json.bak (so a later successful upload cannot destroy the recoverable history) and continue with an empty log; the log itself is written to a temp file and renamed into place.	2026-09-18 01:53:52 +02:00
vhaudiquet	85f0d7d92f	put: paginate the Launchpad published-sources lookup The superseded check read only the first getPublishedSources page (Launchpad defaults to 75 entries per page), so a source with a long publication history could hide its true maximum published version and let a superseded upload through, only to be rejected by the queue hours later. Follow next_collection_link (ws.size=100, hard cap of 20 pages beyond which the check errors rather than risk a false 'not superseded').	2026-09-18 01:49:50 +02:00
vhaudiquet	c45edcee76	build: refuse source build of a binary-only changelog entry dpkg-source errors with 'building source for a binary-only release' when asked to -b a tree whose newest changelog entry sets binary-only=yes: the source publication is already in the archive and is not being rebuilt. pkh instead built the fresh .dsc and then produced binNMU-style metadata referencing the previous version's .dsc and tarballs — behavior dpkg does not have at all. Mirror dpkg: run_source_build now refuses binary-only entries outright, which makes the previous-version references, the binNMU Source field and the Binary-Only-Changes handling in the source pipeline dead code — removed. Binary-only metadata stays in the binary pipeline, where it matches dpkg-genchanges/genbuildinfo (diff_binmu_binary_metadata). New tests: a unit test for the refusal, and a failure-parity differential asserting both dpkg-buildpackage -S and the native pipeline reject the same fixture.	2026-09-18 01:13:19 +02:00
vhaudiquet	1fc1d1aa77	build: render the source .buildinfo from its own checksum set The source pipeline used one checksum map for two documents with different content: the .buildinfo (which, like dpkg-genbuildinfo, lists only the referenced .dsc) and the .changes (which distributes the dsc, the tarballs and the buildinfo itself). Because the tarballs and the buildinfo were inserted into the shared map before the signing cascade re-rendered the .buildinfo, every signed source build produced a .buildinfo listing the tarballs — which dpkg-genbuildinfo never emits — and itself, with the stale digest of its own pre-signature content. Split the map: the .buildinfo renders from the referenced .dsc only (refreshed after the .dsc is signed), the .changes keeps the full distribution set with the signed buildinfo's fresh digests. Verified with a throwaway GPG key: the signed .buildinfo lists exactly one entry, the .dsc, matching the signed file.	2026-09-18 00:25:17 +02:00
vhaudiquet	af870cb7cb	build: stop redistributing the previous source on binNMU uploads dpkg-genchanges/genbuildinfo handle a binary-only upload by referencing the previous source version textually (Source: pkg (prev), Binary-Only: yes, Binary-Only-Changes) while distributing no source files at all: pkh instead pulled the previous .dsc and its tarballs into both documents whenever they sat next to the artifacts, re-uploading the whole source on every binNMU. Drop that redistribution (and include_dsc_artifacts with it), and emit the missing Binary-Only: yes field, which the new differential test against real dpkg-buildpackage -b caught. The binNMU case shares its runner with the regular binary metadata differential; a unit test pins the exclusion even with the previous artifacts present.	2026-09-18 00:24:42 +02:00
