Automated release PR for v0.39.0.

Summary by Sourcery

Harden Proxmox detection and dual-role backup handling so residual files do not cause misclassification and partial backups remain accurately represented.

New Features:

  • Improve Proxmox environment detection by distinguishing installed products from residual files and recovering versions from package metadata when commands or version files are inconclusive.
  • Preserve successful role and shared system data from partially failed dual-role backups while recording incomplete roles in manifests and backup status.
  • Use unified environment detection and completed archive targets for restore compatibility decisions.

Bug Fixes:

  • Prevent leftover PBS files, repositories, or empty version files from misclassifying PVE hosts as dual or PBS systems.
  • Avoid treating unreadable package status data as proof that a product is not installed.

Enhancements:

  • Add residue reporting, detection provenance, partial-archive handling, and restore compatibility coverage.

Build:

  • Update Go module dependencies.

CI:

  • Update pinned Codecov and CodeQL workflow actions.

Documentation:

  • Update collector and restore architecture documentation for independent dual-role collection and partial archive compatibility.

Tests:

  • Expand regression coverage for environment detection, version recovery, residue handling, partial dual backups, manifests, and restore compatibility.

Chores:

  • Add v0.39.0 release notes and user guidance.

Summary by CodeRabbit

  • New Features

    • Improved Proxmox VE/PBS detection distinguishes active installations from leftover files and reports residual files without misclassifying hosts.
    • Backups can continue when one side of a dual-role system fails, preserving successful data and recording incomplete targets.
    • Archive metadata now identifies partially collected roles.
  • Bug Fixes

    • Restore compatibility correctly recognizes partial dual-role archives.
    • Version detection more reliably falls back to package information when commands fail or omit versions.
    • Package status reporting now distinguishes unavailable status data from packages that are not installed.
  • Documentation

    • Updated collector and restore documentation to describe partial collection and revised detection behavior.

RetriggerConfidence Score: 5/5

The PR appears safe to merge, with no outstanding correctness, security, or repository-rule issues identified in the reviewed changes.

Summary

This release improves residue-aware Proxmox role detection, preserves successful payloads from partial dual-role collection, records incomplete roles for restore compatibility, and updates dependencies, workflows, tests, and operator documentation.

  • Separates PVE and PBS collection so one successful role can survive failure of the other.
  • Propagates incomplete-role metadata into manifests and restore compatibility decisions.
  • Uses unified environment detection and clearer detection provenance.
  • The changes since the previous review synchronize dpkg diagnostic classification around one status-file snapshot and update restore documentation to match existing hostname fallback behavior.

tis24dev and others added 13 commits September 16, 2026 21:36
Removing proxmox-backup-server takes away everything the package ships: its binary,
its share directory, its dpkg stanza. It does not take away /etc/proxmox-backup or
/var/lib/proxmox-backup. Those are created at runtime, belong to no package (dpkg -S
finds nothing for either, measured on PBS 3.4.9 and 4.2.0) and the server postrm
leaves them alone even on purge. The detection ladder ends on a directory rung, so
on a host in that state a directory that outlived its product is the only evidence
of PBS, and the verdict is dual.

The run then aborts on proxmox-backup-manager, a command the host does not have, and
the abort discards the PVE payload that was already collected (issue #315).

These tests state the verdict the host deserves and fail today. They cover the live
shape, the same host under SYSTEM_ROOT_PREFIX, the second candidate directory alone
(deleting /etc/proxmox-backup changed nothing because the ladder walks the whole
list), and an empty version file. Two of them are non-regressions rather than new
claims: a coinstalled host must stay dual (issue #197, the request that produced
dual support) and an installed PBS under a prefix must still be found without
running a command (issue #255).

DetectionStep.Residual and EnvironmentInfo.PVEResidual/PBSResidual land here so the
red is behavioural rather than a build failure. Nothing populates them yet.

No release note: this commit changes nothing an operator can observe.
Detection walked a ladder of markers and returned at the first one that fired, with
every rung weighted the same. The last PBS rung is a directory, so on a host where
proxmox-backup-server had been removed the verdict was dual: /etc/proxmox-backup and
/var/lib/proxmox-backup are made at runtime, are owned by no package (dpkg -S finds
nothing for either on PBS 3.4.9 or 4.2.0) and the server postrm leaves them alone
even on purge. Everything the package ships had gone; what PBS itself created stayed,
and that was what decided.

The recipe then ran pbs_runtime_core, which treats proxmox-backup-manager as
critical, and the whole collection aborted on a command the host never had. The PVE
payload was already collected at that point and went out with the workspace, so the
host had no backup at all (issue #315).

A marker now either proves an install or it does not, and only the first kind ends a
ladder. Proving an install means the command answering, a dpkg stanza, a binary the
package ships, a package-owned share directory, or a version file with a version in
it. The rest are residue: a directory no package owns, an empty version file, and an
apt source, which was never evidence of an install and matches the pbs-client
repository Proxmox tells you to add on hosts that are not PBS.

Residue is recorded rather than dropped. It is the reason an operator expected the
other verdict, so the rungs are still walked, the trace marks them as residue instead
of a miss, EnvironmentInfo carries the first one per product, and a run reports it at
warning: a debug-only line does not reach the person reading an unexpected type. When
nothing at all is detected, the error now separates "residue but no install" from "no
Proxmox here", because under SYSTEM_ROOT_PREFIX the first usually means the mount
carries /etc but not the /usr and /var that hold the package evidence.

TestDetectionProvenanceNamesDecidingMarker asserted the old verdict and now asserts
this one. The "via sources" and "via directories" subtests did the same for each half
of the ladder and are inverted with them. Verified on pve-test (PVE 9.1.9 with PBS
4.2.0 coinstalled), which still reports dual with both halves decided by their
command and no residue.
DetectCurrentSystem carried its own rule, and the rule had rotted. hasPBS was
`/etc/proxmox-backup` OR `/usr/sbin/proxmox-backup-proxy`, and that second path does
not exist on PBS 3.4.9 or on 4.2.0: the proxy is a systemd unit, not a binary on
PATH. So the OR was never a choice between two proofs. Every PBS decision on the
restore side rested on one directory, the same directory that turned a PVE-only host
into a dual backup in issue #315, and it rested on it with no ladder behind it: no
dpkg stanza, no version, no package-owned file.

That mattered beyond the label. SupportsPBS() gates the staged PBS apply, the PBS
access-control and notification paths, datastore directory recreation, the mount
guard, and NeedsPBSServices, which asks systemd to stop proxmox-backup-proxy and
proxmox-backup. The common `ssl` category lists ./etc/proxmox-backup/proxy.pem among
its paths and shouldStopPBSServices reads the category definition rather than the
archive, so selecting SSL on a host with leftovers was enough to send the restore
stopping services that host does not have.

It now delegates to environment.Detect, so a host cannot be one type while being
collected and another while being restored onto. detectEnvironment is the seam for
tests, mirroring compatFS.

The three table cases built their verdict by creating directories on the fake
filesystem, which is exactly the rule being removed; they now stub the verdict and
assert the mapping, and the rule itself stays covered where it lives. Two cases are
added for what this changes: a host whose only PBS evidence is residue restores as
PVE, and a nil verdict fails closed to unknown rather than to PVE.
pbs_validate ran a bare Stat on the PBS configuration directory and logged
"Detected %s, proceeding with PBS collection". That is a detection sentence, and the
directory it stats is the one no package owns and no removal deletes, so on the host
in issue #315 this was the third place in the codebase to conclude PBS from a
leftover. It agreed with a type that was already wrong and let 25 more bricks run
before the recipe hit the command that is not there.

The type is settled before any recipe runs. Reaching this brick means PBS is
installed, so a missing configuration directory is a genuine anomaly on a genuine PBS
node rather than evidence about what the host is, and the error says that instead of
"not a PBS system".

No release note: the type is already correct by the time this runs, so the message
only changes for an operator who is on a real PBS node with its configuration
directory missing.
…ayload

Two independent losses, both visible on the host in issue #315.

CollectAll returned as soon as the role-specific collection failed, and the common
system collection sits after that switch. So a run that lost its PBS half also lost
the network, storage-stack and hardware snapshot, which have nothing to do with which
hypervisor the host is. The role error is now held until the common payload has been
collected, and then returned unchanged.

The dual recipe was PVE bricks and PBS bricks concatenated into one fail-fast list.
On that host 34 PVE bricks and 25 PBS bricks completed, the sixtieth aborted on a
command the host does not have, and the workspace holding all of it was deleted: the
node ended the night with no backup because of a role it does not run. The halves now
run as separate recipes over the shared state, and one failing leaves the other
standing. Both failing is still an error, because then there is no role payload to
keep and an archive of system files labelled dual would be worse than none.

A kept half is not a quiet half. The role that did not finish is reported twice at
warning and written into the manifest as incomplete_targets with its reason. Warning
rather than error is the exit code: an error marks the run a failed backup, and this
run produced an archive worth keeping, while a warning still promotes it off clean so
a monitor sees the night was not normal.

newDualRecipe has no caller left and goes, along with its entry in the recipe
well-formedness test; the two recipes it concatenated are already covered there.
The table is an inventory: every marker in it answers YES or NO. These two answered
only when the package was installed, which is the one case that needs no explaining.

On the host in issue #315 the table listed nine PBS markers, all of them NO, and
silently omitted the tenth. The omitted one was the decisive evidence: that
proxmox-backup-server is not installed at all. An absent line reads as a check that
never ran rather than as a negative answer, so the table said least exactly where it
mattered most, and the installed version goes on the line now too.
detectPVEViaSources, detectPBSViaSources and detectViaDirectories stopped being part
of detection when the ladder inlined its rungs, and nothing in the package has called
them since. Six tests kept calling them, so the package looked covered where
production code no longer ran: two of those tests only asserted that the function does
not panic.

The cases worth keeping are pointed at the helpers detection actually uses,
firstMatchingSource and firstExistingDir, so the same behaviour stays covered on the
code path that runs.

No release note: nothing an operator can observe.
…version

The command rung returned "installed, version unknown" when the probe failed, and
that stopped the ladder one step above dpkg, which holds the real version. So a run
reported a host with no version at all while the number sat in the next rung down.

It is not a rare path. pveversion takes 4.4 to 5.2 seconds on pve-test and
commandTimeout is 5, so it times out on nothing more unusual than a busy node. Before
this, the probe on that host printed PVEVersion "" and a combined version of the PBS
half alone; after it, pve=9.1.9,pbs=4.2.0.

The probes now report three outcomes instead of two. markerInstalledNoVersion says
the binary is on PATH, so the product IS installed, and this run did not produce a
version: the ladder keeps walking for one, and falls back to "unknown" only if every
later marker misses too. It is deliberately not markerResidual, which says the
opposite about whether the product is there.

Found while verifying the issue #315 fix on a real host, not part of that fix. It is
its own commit so it can be judged, or reverted, on its own.
warnDetectionResidue landed with the detection fix and had no test. The case worth
pinning is the quiet one: detection returns at the first marker that proves an install
and never reaches the residue rungs, so a healthy host of either kind records nothing
and must print nothing. A line that fired on every run would be ignored by the time it
mattered, which is the run where the type is not what the operator expected.

Also pinned: one line per product that left something behind, and nil arguments, since
this runs on the bootstrap path before the main logger exists.
An 81-agent review of the eight commits raised 38 claims; 28 survived two skeptics
each. This closes the ones that were about the code rather than about wording, plus
the wording that was wrong.

The one that mattered: incomplete_targets was recorded only in the collection
manifest, and that manifest carries a comment saying restore never opens it. The
record restore actually reads is the archive sidecar, so a dual archive that lost its
PBS half still declared targets pve+pbs and cleared ValidateCompatibility against a
dual host as a whole archive would, with the PBS categories offered and nothing behind
them. The gap now travels in the sidecar, and DetectBackupType subtracts it: a run
that lost a half ships an archive of the other half and is treated as one. Losing both
halves reports unknown rather than claiming a product.

Two defects in code this branch wrote:

- CollectAll returned the bare context error when a cancelled run reached the system
  phase, dropping roleErr, so the log said "context canceled" where the phase that
  died had a name. Both are joined now.
- The both-halves-failed error wrapped the PVE cause with %w and the PBS cause with
  %v, so the PBS cause was in the text but unreachable to errors.Is.

Provenance: the versionless-command rung is a hit that keeps walking, and decidedBy
returned the first hit, so PVESource named the probe that had failed while dpkg one
rung down supplied the version. Steps that keep walking are marked Continued and
skipped when naming the decider, falling back to the command when nothing else
answered.

The residue warning no longer declares the package absent. dpkgPackageInstalled
returns false both when the stanza says not-installed and when the status file cannot
be read, and under SYSTEM_ROOT_PREFIX the second is the usual case: a mount carrying
/etc but not the /var holding the package database. It now reports what was observed,
that nothing proved the product installed.

Also: WriteManifest read c.incomplete without the lock every other access takes; a
dual run that lost a half logged "collection completed"; the release note called a
warning a "notice" while it demotes the run to exit 1; an orchestrator test started
asking the build host what it is once DetectCurrentSystem began running real probes;
TestIncompleteTargetTravelsInTheManifest asserted an in-memory field and never wrote
a manifest; the PBS half of the versionless-command fix had no test; the rootPrefix
safety comment still claimed both setters are bootstrap-only, which the restore
delegation makes false; two comments named outcomes the code does not return; and the
restore and collector docs still presented the deleted DetectCurrentSystem body and
newDualRecipe as current. Three files this branch touched were not gofmt-clean.
…n its exit code

A residue is recorded only when a product was NOT proved installed, and enumerating
every mount shape with both products installed shows that leaves exactly two
situations, never a third:

  - the verdict is pve, pbs or dual: the product is genuinely absent, the backup is
    complete and correct, and the leftovers are untidy filesystem rather than a fault.
  - the verdict is unknown: a real fault, and it already carries three warnings that
    decide the exit code between them - the detection error, which now names the
    residue itself, the host-backup mount warning, and the collector reporting that it
    is collecting generic system info only.

There is no mount shape that yields a confident wrong type alongside a residue, and
the reason is structural: /var/lib/dpkg/status is one file covering both products, so
it either proves both or neither. The asymmetry that would make a residue the only
hint of a missed half cannot arise.

So warning level bought nothing and cost plenty. It pinned an otherwise healthy host
at exit 1 on every run over leftovers its operator often cannot delete, since
/var/lib/proxmox-backup belongs to the PVE file-restore stack: a nightly monitor
gating on the exit code would alarm forever on a node whose backups are fine. The host
in issue #315 is exactly that host.

The test now pins the LEVEL rather than the line count, through ReplayConsoleSince,
which replays warning and worse only: putting Warning back makes it fail. Verified by
doing precisely that before committing. The release note no longer promises the exit 1
it was describing, and warnDetectionResidue is renamed reportDetectionResidue because
it no longer warns.

File-Level Changes

Change Details Files
Correct Proxmox environment detection by distinguishing installed-product evidence from leftover filesystem residue.
  • Treat unowned directories, repositories, and empty version files as non-decisive residue.
  • Continue past versionless command results so package metadata can provide versions.
  • Record detection provenance and report residue informationally without changing clean-run exit status.
  • Use the unified detection ladder for restore-side host classification.

Make dual-role collection resilient to failures in one product role while preserving accurate run and restore metadata.
  • Run PVE and PBS recipes independently over shared state instead of using one fail-fast combined recipe.
  • Continue collecting common system data after role failures and retain the successful role payload.
  • Record incomplete roles with causes, warning-level reporting, and concurrency-safe snapshots.
  • Propagate incomplete targets into collection statistics and the archive sidecar manifest.
  • Classify partial archives by completed targets so restore compatibility detects partial rather than full dual backups.

📝 Walkthrough

Walkthrough

The pull request separates installation evidence from residue, preserves successful portions of partial dual-role backups, records incomplete targets in manifests, and updates restore compatibility classification. It also adds tests, documentation, dependency updates, release notes, and pinned workflow action updates.

Changes

Proxmox detection and partial collection

Layer / File(s) Summary
Residue-aware environment detection
internal/environment/detect.go, internal/environment/*test.go
Detection distinguishes absent, residual, versionless, and installed markers. Residual paths no longer determine the host type. Package metadata can provide versions when commands fail or return no version.
Partial dual-role collection and manifest propagation
internal/backup/*, internal/orchestrator/orchestrator.go, internal/orchestrator/backup_run_helpers.go, docs/COLLECTOR_ARCHITECTURE.md, docs/DEVELOPER_GUIDE.md
PVE and PBS recipes run separately. A failed role is recorded while successful payloads and common system data remain. Incomplete targets and reasons are written to manifests and backup statistics.
Restore detection and compatibility
internal/orchestrator/compatibility.go, internal/orchestrator/*test.go, docs/RESTORE_TECHNICAL.md
Restore system detection uses environment detection. Backup classification removes incomplete targets before determining the archive type.
Residue reporting and supporting updates
cmd/proxsave/*, .github/workflows/*, go.mod, internal/whatsnew/registry.go
Residue is logged at INFO level. Tests cover logging behavior. Workflow actions and Go dependencies move to newer versions, and release notes describe the changes.

Hey - I've found 2 issues

## Individual Comments

### Comment 1
<location path="internal/environment/detect.go" line_range="467" />
<code_context>
+func detectPVE(trace *detectionTrace) (string, bool, string) {
+	residue := ""
+	noteResidue := func(marker, target, note string) {
+		trace.residue(productPVE, marker, target, note)
+		if residue == "" {
+			residue = fmt.Sprintf("%s (%s)", marker, target)
</code_context>
<issue_to_address>
**issue (bug_risk):** The residue callbacks dereference `trace` unconditionally, so `detectPVE(nil)` and `detectPBS(nil)` panic when an apt-source, leftover-directory, or empty-version-file marker is encountered. Existing callers such as `GetVersion` and tests intentionally pass a nil trace, making any such host crash instead of returning the detection result.

**Triggers:** When detection is invoked without provenance tracing and the product has residue but no earlier install marker.

**Suggested fix:** Guard the trace call in the residue callbacks, or make `detectionTrace.residue` safely accept a nil receiver like the other detection helpers.
</issue_to_address>

### Comment 2
<location path="internal/environment/detect.go" line_range="1022" />
<code_context>
+	// host in issue #315 the table listed nine PBS markers and silently omitted the one
+	// that said proxmox-backup-server is NOT installed, so the decisive evidence read as
+	// a check that had never run. Every other marker here reports YES or NO.
+	for _, pkg := range []string{"pve-manager", "proxmox-backup-server"} {
+		if version, ok := dpkgPackageInstalled(pkg); ok {
+			add("dpkg %s: installed (%s)", pkg, version)
+		} else {
+			add("dpkg %s: not installed", pkg)
+		}
 	}
</code_context>
<issue_to_address>
**issue (bug_risk):** The marker snapshot labels every false result as `not installed`, but `dpkgPackageInstalled` also returns false when the dpkg status file cannot be read. Under `SYSTEM_ROOT_PREFIX` with a mount that lacks `/var/lib/dpkg/status`, the snapshot therefore reports an unverified package as absent and gives a false explanation of the detection result.

**Triggers:** When `MarkerSnapshot` runs against a prefixed root whose dpkg status file is missing or unreadable.

**Suggested fix:** Return and report a distinct status-file-error outcome, or label the false case as `not proven installed` rather than `not installed`.

```suggestion
			add("dpkg %s: not proven installed", pkg)
```
</issue_to_address>

Sourcery assessment

Needs a human reviewer. 2 findings to address first, and a faulty detection or dual-collection change could create backups missing an entire PVE or PBS role, or cause restore to classify an archive incorrectly; those archives persist after reverting the code and may be relied on later, although the incomplete-role manifest makes the impact bounded and rerunning the backup can repair it. The workflow and dependency updates are otherwise ordinarily reversible.

Blocking findings: internal/environment/detect.go:467, internal/environment/detect.go:1022

…bsent

dpkgPackageInstalled answers false for two different facts - the package is
absent, or the status file could not be read at all - and the marker table
printed "not installed" for both. On a SYSTEM_ROOT_PREFIX mount that carries
no /var/lib/dpkg/status, that line stated as checked something the run had
never been able to check, and the marker table is the whole explanation an
operator gets for a detection verdict.

markerLines now reads the status file once and separates the two: a read
error prints "not proven installed (<error>)", naming the path the read
failed on, and "not installed" keeps meaning exactly that. dpkgPackageInstalled
is left alone - it has three callers and two of them are the detection ladder,
which is not what this fixes.

Also realigns the DetectBackupType sample in RESTORE_TECHNICAL.md with the
function it documents. The prose above it already described subtracting
incomplete roles; the code block still showed the body from before that
change, in a file that declares itself the source of truth for restore
compatibility.

Both found by reviewers on the v0.39.0 release PR (#322).

Comment thread internal/environment/detect.go Outdated
…a later one

The previous commit read the status file once to tell "absent" from "could not
read", then called dpkgPackageInstalled per package - which reads the file
again. Three reads, and the verdict printed came from a different read than
the one the check was based on. A status file that stopped being readable
after the check would have been reported as a package simply not installed:
exactly the claim the check exists to stop making.

markerLines now reads once and classifies both packages against that data.
dpkgPackageInstalled keeps its signature, so detectPVE and detectPBS - the
other two callers, and the detection ladder itself - are untouched; its parse
half moves into dpkgPackageInstalledIn, which is what markerLines calls.

TestMarkerTableClassifiesBothPackagesFromOneDpkgRead serves the status file
once and refuses every later read of it. Against the previous commit it fails
with "status exists: YES" directly above "dpkg pve-manager: not installed",
on a host where pve-manager is installed.

Also completes the DetectBackupType sample in RESTORE_TECHNICAL.md: the
comment said hostname heuristics and the body returned SystemTypeUnknown
without them, while the real function does check the hostname.
