Automated release PR for v0.46.1.

Summary by CodeRabbit

New Features
- --upgrade-config --dry-run now previews configuration changes without modifying files.
- Filesystem details can show symlink targets, and Ceph filesystems are recognized.
- Configuration values support $$ for a literal dollar sign.
Bug Fixes
- Improved backup scheduling, installation checks, and handling of disabled secondary storage.
- Cloud backup copies preserve appropriate file permissions; log-write failures are surfaced in run summaries.
- Notification and update errors provide clearer status information while limiting potentially sensitive response details.
- Mail queue counts now reflect messages rather than recipient addresses.
Documentation
- Clarified cloud log path behavior and dry-run compatibility.

A backend credential passed in RCLONE_FLAGS (--s3-secret-access-key=X, --webdav-pass X) was written in plain text to the run log, which is copied to SECONDARY_LOG_PATH, uploaded to CLOUD_LOG_PATH and attached by --support: nine DEBUG lines print the full rclone argv (filesystem check, write test, copy, both verifications, delete), and with -vv in RCLONE_FLAGS rclone itself echoes its argv into the stderr that errors carry to WARNING/ERROR lines (measured on pve-test, rclone 1.60.1). NewCloudStorage now registers every RCLONE_FLAGS value (the text after '=' or a token that is not a flag) as a log secret, before the first rclone call, so each line shows "--s3-secret-access-key=************EKEY". The logger skips values under 6 characters, so the shipped flags stay readable and no line changes on the default configuration. Audit finding storage-10 (audit-prod-go-2026-10-26).

For a status the startup handshake does not know, the WARNING printed on every centralized run read "Telegram: 502 - Unexpected response: " plus the raw answer, up to the 8 KiB read cap: a proxy's 502 page spanned 9 physical lines (8 without a prefix), a 5.4 KB body 89, and its escape and bidi bytes reached the console and the run log raw. The setup screens showed the same Message. Message now names the status only, as the 403/409/422/426 branches do: "Telegram: 502 - Unexpected response" on the run, and the same text on the CLI and TUI setup screens. The answer stays in the DEBUG bodyPreview line printed before it, quoted and cut to 200 characters. The error of the 403/409/422/426 branches, printed at DEBUG as "Telegram connection error", carried the raw body too; it is now quoted and cut the same way. Audit finding notify-health-7 (audit-prod-go-2026-10-26).

0ad31c9 registered the RCLONE_FLAGS values as log secrets but missed three forms (automated security review of that commit): 1. a separate value that starts with '-' ("--ftp-pass -x...") was taken for a flag and left in plain text. Every token that is not a --flag is now a value; 2. rclone -vv echoes its argv with %q, so a value holding a quote, a backslash or a control byte appears escaped there, a form the mask did not match. That form is registered too; 3. a failed copy keeps the last 4 KiB of rclone's output, and the cut can start inside an echoed value, whose rest the logger no longer recognises. The output is now masked before the cut. No line changes beyond the approved mask. Audit finding storage-10 (audit-prod-go-2026-10-26).

d72453a put two raw U+202E runes in the test source (an editing tool turned the \u202e escape into the rune). Same string at run time; the source no longer holds an invisible reordering character.

…lines A failed endpoint's answer was printed raw in the visible line of every attempt (4 with the defaults): a proxy's 502 page made 38 physical lines with its escape and bidi bytes, and the read had no limit, so an 8 MiB answer made an 8 MiB WARNING. Measured side effects: a line over 1 MiB stops the run log re-parse (exit 0 instead of 1), and an answer line shaped like "[ts] ERROR" was counted as a backup error (exit 4). The 5xx line also said "will retry" on the last attempt. The answer is now read up to 8 KiB and shown only in the DEBUG "Response body" line, with the endpoint's credentials masked, on one line of printable characters, cut to 200. The errors no longer carry it. Approved texts: ERROR ❌ Bad request (HTTP 400) ERROR ❌ Forbidden (HTTP 403) WARNING ⚠️ Rate limited (HTTP 429), attempt 1/4 WARNING ⚠️ Server error (HTTP 502), attempt 1/4 WARNING ⚠️ Unexpected status (HTTP 405), attempt 1/4 Found while fixing audit finding notify-health-7: same raw server body in a visible line, at a sibling site.

A non-200 answer from GitHub went raw into the ERROR line of proxsave --upgrade (and the session log of the dashboard's Run upgrade): a proxy's 502 page made 8 lines with its escape and bidi bytes, for the release API and for the asset downloads alike. The error now names the status with Go's own status text, plus, for the release API, the message of GitHub's JSON error, which is where its rate limit says why. The answer itself goes to a DEBUG line, on one line of printable characters, cut to 200. Approved texts: failed to fetch latest release: status 502 Bad Gateway failed to fetch latest release: status 403 Forbidden: API rate limit exceeded for <ip>. (...) Upgrade failed: failed to download archive: download failed with status 502 Bad Gateway Upgrade failed: failed to download archive: download failed with status 403 Forbidden Found while fixing audit finding notify-health-7: same raw server body in a visible line, at a sibling site.

…wer excerpt 20241ef masked the endpoint URL whole in the DEBUG excerpt of an endpoint's answer (automated security review of that commit): an error page echoes the requested path alone, and a webhook URL often carries its token in a path segment; query values and header values can be credentials too. Those are now masked as well, before the cut to 200 characters. DEBUG only.

Three senders put a non-2xx answer raw into their error, printed at DEBUG twice (by the sender and by the adapter's failure detail): the bot server's get-chat-id at send time (up to 8 KiB), api.telegram.org in personal mode (no read limit at all) and the Gotify server (2 KiB). A proxy page split those lines with its escape and bidi bytes. No visible line carried it: the adapter's WARNING is generic. The errors now name the status only. The answer goes to one DEBUG line of printable characters, cut to 200, with the bot or Gotify token masked before the cut; api.telegram.org is read up to 8 KiB. No visible text changes. Found while fixing audit finding notify-health-7: same raw server body, at sibling sites.

…swer excerpt Second round of the automated security review on the DEBUG excerpt of an endpoint's answer: the masking missed the URL's userinfo, the path segments as sent (percent-encoded), the raw query values, the basic-auth header made from AUTH_USER and AUTH_PASS, and a token inside a header value ("Bearer <token>"). Those are masked too, before the cut. DEBUG only. Values under 6 characters stay unmasked, as everywhere in the logger.

…in the excerpt Third round of the automated security review on the DEBUG excerpt of an endpoint's answer: the basic-auth header made from the URL's userinfo, and query pairs with no '=' or a credential as key, were not masked. They are now, before the cut. DEBUG only.

ParseLogCounts, whose counts set the exit code, the healthchecks ping and the metrics, read the run log through a bufio.Scanner capped at 1 MiB and never checked its error: a longer line stopped the parse without a word, so that line and every line after it went uncounted. Measured: an ERROR after a 2 MiB WARNING left the exit code at 1 instead of 4; with the long line first the run exited 0 and the healthchecks ping was green, while the footer, which reads the logger's own counters, showed the warnings. Present since the first Go port (3808e6c). Lines are now read with a bufio.Reader of any length: the first 64 KiB of each is classified (messages are cut to 300 bytes anyway) and the rest is skipped. A read error that is not the end of the file still ends the walk with what was read so far, as before. No visible text. Found while verifying the webhook fix (raw 8 MiB answer in one line).

Every string value of backup.env goes through os.Expand, and a '$' could not be written at all: quotes are stripped before the expansion, a backslash stays and the name after it is still looked up, and "$$" was consumed whole. A webhook password "p$ssw0rd" reached the endpoint as "p" on every notification, with no line saying the value had been altered; an HMAC secret or token with a '$' broke the same way. "$$" is now a literal '$', in every value (no per-variable exception, as decided for paths). Only values holding "$$" change meaning, and those always expanded to nothing before. Approved docs texts in CONFIGURATION.md: the personal-scripts paragraph ("`$$` is a literal `$`", "Write `$$` where the path really contains a `$`."), the path resolution note, and a new line under the per-endpoint webhook block. Audit finding ui-config-5 (audit-prod-go-2026-10-26).

Lint (modernize): errors.As with a declared target becomes errors.AsType in the two callers added by ed68c42, and the startup Telegram test ranges over strings.SplitSeq.

…on gets its target's filesystem Filesystem detection matched the path string against /proc/mounts and never followed a symlink. A BACKUP_PATH, SECONDARY_PATH or log path that is a link into an NFS root_squash share was seen as the filesystem holding the link (ext4, with ownership): the security check then tried to fix the share's owner, refused to chown the symlink with an ERROR, and with the defaults every run stopped at exit 14 before the backup (measured on pve-test). Primary and secondary also warned "permissions not set" on every run. The mount is now found by device: the st_dev of the path (the stat follows links) against /proc/self/mountinfo, the deepest entry holding the resolved path. A device no mountinfo entry carries (btrfs subvolumes report their own) falls back to the path match, on the resolved path. Measured on pve-test after the fix: "nfs4 (no ownership)", the security check skips the share, 0 errors. The Filesystem line names the target when the path is reached through a link. Approved text: Filesystem: nfs4 (no ownership) [network] [mount: /mnt/s6nfs] [link to: /mnt/s6nfs/proxsave] Audit finding storage-6 (audit-prod-go-2026-10-26).

…config previews Six modes return before the runtime, where --dry-run is honoured, and none of them read the flag, so they wrote for real while the operator asked for a simulation. Measured on pve-test: --upgrade-config and --upgrade-config-json rewrote backup.env, --newkey replaced the recipient, --new-install deleted backup/, configs/ and log/. --upgrade-config --dry-run now runs the existing --upgrade-config-dry-run preview. The other five are refused with exit 2, like --restore and --upgrade. Approved texts: --dry-run is not supported with --install or --new-install: the installer always writes the installation. --dry-run is not supported with --newkey: it always replaces the encryption recipient. --dry-run is not supported with --decrypt: it always writes the decrypted archive. --dry-run is not supported with --upgrade-config-json: use --upgrade-config-dry-run to preview the changes. docs/CLI_REFERENCE.md lists the refused modes and the preview (approved). --upgrade calls --upgrade-config-json without --dry-run: unaffected. Audit finding cmd-main-5 (audit-prod-go-2026-10-26).

…witch to cron The install's cron path wrote the cron line, which reports its failures only as WARNINGs, and then removed the daemon unit whenever one was installed. With a crontab that refused the new table (Debian cron rejects the whole table for one bad line) or no crontab binary, the host ended with no daemon and no cron line, under a green "Installation completed". --daemon-remove already reads the crontab back (5098c4d); the install path never got it. The crontab is now read back after the write. Without the proxsave line the daemon is kept, so it keeps scheduling the backup, and the install fails; a first cron install without the line fails too. Approved texts: WARNING daemon: the cron entry could not be written, so the daemon service was left in place and keeps scheduling the backup. ERROR the cron entry could not be written ERROR the cron entry could not be written, so no scheduler is installed followed by the existing "Installation failed" banner. Audit finding cmd-main-7 (audit-prod-go-2026-10-26).

…out ownership With CLOUD_REMOTE as a local directory on a filesystem without ownership (NFS root_squash, CIFS), the backup set and the log rclone copied there kept rclone's 0644, while the Secondary's copies on the same mount ended 0600 (log 0640); the archive is unencrypted by default. docs/CLOUD_STORAGE.md promises the Secondary's owner and mode. The chmod was skipped together with the chown, though it needs no ownership. On such a filesystem the owner is still left alone, but each file of the backup set takes its source file's mode, as the Secondary's copy does, and the log takes the Secondary log's 0640. A failure stays at DEBUG. No visible line changes. Measured on pve-test with real rclone on an NFS root_squash share: 644 before, 600 after. Two tests that pinned the 0644 now expect the new modes. Audit finding storage-7 (audit-prod-go-2026-10-26).

…d copy modes Automated security review of 6439cd8: when the source mode could not be read the copy was left at rclone's 0644, and the chmod followed a symlink, in a directory that can be a share other hosts write to, so a link swapped in for a copy could redirect a root chmod to another file. The copy now gets 0600 when its source mode is unknown, and both the backup-set chmod and the log's 0640 go through safefs.Lchmod, which refuses a symlink at the final component. Failures stay at DEBUG, as on the Secondary. No visible line changes. Audit finding storage-7 (audit-prod-go-2026-10-26).

…ISSIONS With SET_BACKUP_PERMISSIONS=true every run, --install and --upgrade walked SECONDARY_PATH and SECONDARY_LOG_PATH recursively even with SECONDARY_ENABLED=false: the loader keeps both paths, and the pass chowned to BACKUP_USER and re-moded every entry of a directory the backup no longer uses (measured on pve-test: 11 of 11 entries, dirs 0755 to 0750). Every other consumer checks the flag; the Bash version gated this step on it too. config.ActiveSecondaryPaths returns the two paths only when the secondary is enabled, and the pass uses it. The test that built a secondary without SecondaryEnabled now sets it. Approved docs texts: SECURITY.md "every run walks `BACKUP_PATH` and `LOG_PATH`, plus `SECONDARY_PATH` and `SECONDARY_LOG_PATH` when `SECONDARY_ENABLED=true`", CONFIGURATION.md "(when `SECONDARY_ENABLED=true`)". Audit finding cmd-main-11 (audit-prod-go-2026-10-26).

…dary The security preflight of every run, --install and --upgrade listed SECONDARY_PATH and SECONDARY_LOG_PATH whatever SECONDARY_ENABLED said. The loader keeps both paths when the secondary is off, so the preflight created a missing one at 0755 root:root (on the root filesystem when its mount was absent, hidden later under the mount), and with AUTO_FIX_PERMISSIONS re-owned an existing one to root:root 0755 (measured on pve-test). The Bash version created them only when the secondary was enabled. Both sites now use config.ActiveSecondaryPaths. Two tests that built a secondary without SecondaryEnabled set it. Approved docs text, SECURITY.md: "`SECONDARY_PATH` and `SECONDARY_LOG_PATH` are checked, and created when missing, only when `SECONDARY_ENABLED=true`." Audit finding platform-3 (audit-prod-go-2026-10-26).

applyBackupPermissions returns nil on every skip, so the install and upgrade footers printed "permissions and ownership normalized correctly (including backup paths)" when BACKUP_USER/BACKUP_GROUP were empty or could not be resolved, or a path could not be read, detected or changed. The TUI install hides the pass's WARNINGs, so nothing on its screen told the operator. Its "warning" branch was dead. The pass now reports what it left undone; the backup run keeps its contract (no error). The footer reads it. Approved texts: Permissions: WARNING (non blocking) - permissions and ownership normalized; backup paths skipped: <reasons> with the reasons "BACKUP_USER/BACKUP_GROUP are empty", "BACKUP_USER/ BACKUP_GROUP cannot be resolved", "<dir> could not be read", "the filesystem of <dir> could not be detected", "<dir> could not be changed" (joined by "; "). A documented skip (filesystem without ownership, missing directory) drops the "(including backup paths)" suffix: "permissions and ownership normalized correctly". The dead branch and its never-printed texts are gone. Audit finding cmd-main-6 (audit-prod-go-2026-10-26).

When the support email could not be sent the operator saw only the adapter's generic "❌ Email: notification failed", nothing naming the support email. Its CRITICAL line and yellow banner were dead code: the notification adapter returns nil for every delivery failure by design, and the outcome is in NotifyResults. The dead branch is gone; the failure branch logs, after the adapter's line, the approved text: WARNING Support mode: FAILED to send support email to <recipient> The exit code does not change (the support email runs after it is set). Audit finding notify-health-2 (audit-prod-go-2026-10-26).

The mail queue count took every mailq line with an "@": postfix prints the sender on the queue-ID line and each recipient on its own, so 3 queued messages read "7 message(s)" (measured on pve-test, postfix 3.10.5), the "increased from X to Y" line was off the same way, and "Large queue detected" fired at 6 real messages instead of 11. The first Go version's comment already meant queue-ID lines. The count is now one per queue-ID line; output with none (exim prints the age first) keeps the line count. Only the numbers inside the existing lines change. Two tests that pinned 4 for a 2-message fixture now expect 2. Audit finding notify-health-4 (audit-prod-go-2026-10-26).

…back On a PBS-only host the recipient fallback parsed /etc/proxmox-backup/user.cfg as PVE's colon lines, but PBS writes it as section-config ("user: root@pam" then indented "email <addr>"), so the email of root@pam was never found there when proxmox-backup-manager failed (measured with pve-test's PBS 4.2.5 file). A section-config reader now handles the PBS file; PVE keeps its colon parser. When the CLI already read the user without an email, the file is no longer read (it holds none either). No INFO or WARNING changes. Approved docs line, TROUBLESHOOTING.md: grep -A5 '^user: root@pam' /etc/proxmox-backup/user.cfg Audit finding notify-health-5 (audit-prod-go-2026-10-26).

The run, install and upgrade footers and the missing-config hint still named "proxmox-backup" as an alias. Install and upgrade delete that entrypoint since 37e9e42 and nothing recreates it, so an operator following the hint got "command not found" (on pve-test only proxmox-backup-client/-manager/-debug exist). The texts were reworded later (7c2b850, 90338af) and kept the alias. Approved texts: proxsave - Open the interactive dashboard (runs the backup directly when non-interactive, e.g. cron) Run 'proxsave --install' to create a new configuration The footer line now sits in the same column as the other commands. Audit finding cmd-main-8 (audit-prod-go-2026-10-26).

… 1 when GitHub fails --upgrade exited 2, documented as "Invalid or missing configuration", when the release check could not reach GitHub and when the confirmation got Ctrl+C, SIGTERM, end of input or the idle timeout, while a failed download exited 1. A wrapper reading $? saw a configuration error for a network outage or a Ctrl+C. Now (approved): Ctrl+C or SIGTERM during the check or at the prompt exits 130 with no ERROR line, as backup and restore; end of input or the idle timeout at the prompt prints the existing "Upgrade cancelled by user; no changes were made." and exits 0; GitHub not answering prints its ERROR and exits 1, like a failed download. Docs unchanged: they already give 130 for Ctrl+C/SIGTERM. Audit finding cmd-main-10 (audit-prod-go-2026-10-26).

…sed components" The post-install audit runner swallows every exit status, and the collector never read its own context: a dry-run killed by Esc or by the 90 s bound, or one that stopped early (exit 16, a backup already running), returned no suggestions and no error, shown as the green "✓ NO UNUSED COMPONENTS" (TUI) or "No unused components detected" (CLI). That check is what keeps a stock PBS green by offering to disable the optional collectors. The collector now returns an error for a cancelled or timed-out dry-run and for an exit status other than 0 or 1. Approved texts: a dry-run stopped with Esc shows "Status: NOT CHECKED" with "The dry-run was cancelled before it finished."; the others keep the existing CHECK FAILED screen and CLI WARNING with "post-install audit dry-run failed: context deadline exceeded" or "...: exit code 16". Audit finding ui-config-1 (audit-prod-go-2026-10-26).

On the TUI install, Ctrl+C at the Healthchecks selector came back from the step as "check skipped" (nil: the step also serves the dashboard, where that is right) and on its spinner as the task's own context.Canceled. The install then ran its finalization on the closed session, ended "Installation failed" (exit 2) and did not restore backup.env, while the CLI treats the same Ctrl+C as an abort with the restore. 3774dea meant every optional step to abort on Ctrl+C. After the step, a closed session is now the operator's Ctrl+C: the driver reports it as the other steps do. Existing texts, as approved ("like the CLI"): "Healthcheck setup aborted (interrupted); stopping the install before finalization", the "Installation aborted" banner, exit 0, backup.env restored. As on the CLI, the scheduler reconciliation before the step stays done. Audit finding ui-config-2 (audit-prod-go-2026-10-26).

The daemon-mode writes of backup.env (SCHEDULER_MODE, the schedule adoption) go through a read and an atomic write rooted at the file's parent, which refuse a final component that is an absolute or escaping symlink ("openat backup.env: path escapes from parent"), while the loader and the upgrade merge follow it. On such a link the switch to the daemon removed the cron line, lost its schedule (the daemon ran at 02:00), warned and then reported the daemon enabled, and the dashboard showed a green INSTALLED over a backup.env still saying cron (measured on pve-test). The link is now resolved first and the write roots at the target's parent, as resolveSystemCronPath does for /etc/cron.d; the link stays a link. An adoption that cannot read backup.env, for any cause, now gets the WARNING block a failed write already had, with the approved reason "backup.env could not be read" (it was DEBUG only while the cron line was removed anyway). Docs unchanged: they still advise a regular file. Audit finding cmd-daemon-2 (audit-prod-go-2026-10-26).

…ommand The system-crontab extractor (/etc/crontab, /etc/cron.d) returned the command field as it was, so "0 2 * * * root TZ=UTC /usr/local/bin/proxsave" (or PATH=/LANG= in front) was invisible to the four checks that use it: the --upgrade retrofit refusal, the daemon setup warning, the --daemon-remove advisory and the schedule seed. A retrofitted daemon then ran beside a live /etc schedule. The user-crontab extractor steps over such assignments since 3eac58c; its own comment promised the two "can never drift". Both now take the command word through one helper, cronCommandWordAt(fields, n), so the step-over (and its guard for an assignment it cannot lex whole) is shared. No new text: the existing lines appear for these hosts. /etc stays read-only to ProxSave. The comment that said cron does not read /etc/timezone and that TZ= is the ordinary way to pin a job's hour is corrected: cron(8) fires every job in its single timezone from /etc/timezone; TZ= only sets the job's environment (approved). Audit finding cmd-daemon-4 (audit-prod-go-2026-10-26).

A write to the run log that failed for any reason but a timeout (disk full, EIO, a read-only remount, a closed fd) was dropped without a word and the sink stayed armed. The run log - copied to the secondary and the cloud, attached to the email - silently lost its WARNING and ERROR lines, and the exit code and the healthchecks ping, computed by re-reading that file, read a clean run while the footer counted the issues (measured on a full tmpfs: file 0 bytes, exit 0). Only the timeout path had been decided (F11-04: strikes, marker). Now (approved): the first lost line of a series prints, on stdout and counted as a warning, WARNING log file write failed (<cause>); continuing on stdout, lines are missing from the on-disk log and the first line that lands afterwards is preceded in the file by [<ts>] WARNING log file writes failed (<cause>); <n> lines missing from the on-disk log here The sink stays armed, as the strike rule wants for a passing stall. When any line of the run missed the file (a write error, a timeout, the sink disabled), the re-parse takes the higher of the file's counts and the logger's own, which also closes the same hole on the timeout path. Audit finding platform-5 (audit-prod-go-2026-10-26).

With the template defaults (CLOUD_REMOTE_PATH=/proxsave/backup, CLOUD_LOG_PATH=/proxsave/log) on an sftp or ftp remote the backups went to ~/proxsave/backup (the leading "/" of the backup path is dropped, decided 2026-10-04 so existing sftp backups do not move) and the logs to /proxsave/log at the server root; a non-root login got "Log not copied to cloud" (measured on pve-test with real rclone over sftp). On S3/Drive the two forms are the same. As approved, nothing moves for existing installs: the template (and so the install wizard's default) becomes CLOUD_LOG_PATH=proxsave/log, and the comment and docs say that a leading "/" is kept here: backup.env: # - With a leading /: /proxsave/log (on sftp, ftp and local remotes: an absolute path on the server, not under the home directory) CLOUD_STORAGE.md: Unlike `CLOUD_REMOTE_PATH`, a leading `/` is kept: on an `sftp` or `ftp` remote `/proxsave/log` is an absolute path on the server, not under the login user's home directory. The install characterization goldens change only by that comment and the prompt default; a test name that said the slash is "stripped" while asserting it is kept now says "kept".

Lint (modernize) on the test added by 61425db.

--decrypt set its session logger from DEBUG_LEVEL only and never read --log-level: with --log-level debug its log had no DEBUG line (measured on pve-test; --restore wrote 154), and --log-level error still printed the INFO lines. The docs and --help give the flag no mode exception. Decrypt now resolves the level with resolveRunLogLevel, the backup and restore rule (approved): DEBUG_LEVEL is the base, --log-level overrides it. No new text; the decrypt log gains the DEBUG "main run: log_level=<LEVEL>" those runs already write. The interactive-stdin check gets a test seam. Audit finding cmd-main-9 (audit-prod-go-2026-10-26).

The loader still read DISABLE_COLORS and let it override USE_COLOR, from the file and the environment, while the integrity check reported "DISABLE_COLORS is not a known variable and is ignored": an operator who deleted the line as told got the colors back. 935fcc5 removed the legacy names from the loader and missed this one; no Go writer ever wrote it, so it comes only from a copied Bash env. As approved, it is no longer read: the integrity line becomes true and USE_COLOR decides alone. Three comments that named it as a live knob now name USE_COLOR. Audit finding ui-config-3 (audit-prod-go-2026-10-26).

Personal scripts are executed from a pinned descriptor, /proc/self/fd/3, so a swapped path cannot change what runs (f882c8f). For an interpreted script that also sets $0, BASH_SOURCE, Python's __file__ and Perl's $FindBin::Bin to /proc/self/fd/3: dirname "$0" finds nothing next to the script, silently. The docs tell the operator to give the script a shebang and never said so. Behaviour unchanged (approved, docs only). The approved sentence, in DAEMON.md after "give it a shebang" and in CONFIGURATION.md's personal-scripts paragraph: An interpreted script sees its own name as `/proc/self/fd/3`, not as the configured path: `$0`, `BASH_SOURCE`, Python's `__file__` and Perl's `$FindBin::Bin` all carry it, so `dirname "$0"` points at `/proc/self/fd`. To find files next to the script, resolve it first: `readlink -f "$0"`, `os.path.realpath(__file__)` or `$FindBin::RealBin`. Audit finding cmd-main-4 (audit-prod-go-2026-10-26).

…robe decides The filesystem classifier had no case for CephFS: the kernel client ("ceph") fell to unknown and ceph-fuse ("fuse.ceph-fuse") to the FUSE rule, both without ownership. On a common PVE destination SET_BACKUP_PERMISSIONS was never applied, the backups stayed root-only, and the security preflight skipped the owner and mode checks of those paths. CephFS takes POSIX ownership unless the client cap carries root_squash. Both clients are now "ceph", a network filesystem, so the existing ownership write probe decides (approved, root_squash included). The lines read "Filesystem: ceph (supports ownership) [network] [mount: ...]" or "ceph (no ownership)" under root_squash; with SET_BACKUP_PERMISSIONS=false the preflight now enforces its checks on CephFS directories as on ext4 (approved side effect). Approved docs line: "POSIX-capable NFS and CephFS mounts requiring specific ownership". pve-test has no Ceph cluster; the classifier and the probe path are tested with the detector's seams.

…fest Deduplication replaces duplicate files with symlinks and records them in var/lib/proxsave-info/dedup_manifest.json, the only input that turns them back into files on restore. The archiver applies the run's exclusion patterns afterwards and drops a match silently: with an operator pattern such as *.json, *manifest* or /var/lib/** the archive shipped the symlinks without the manifest, and a restore brought the duplicates back as links (dangling on a selective restore) with no error. The template and docs patterns do not match. Dedup now checks the manifest path and each directory above it against the run's exclusions first (as writeBackupMetadata does for its file) and, on a match, is skipped for that run. Approved INFO line: Deduplication skipped: the dedup manifest var/lib/proxsave-info/dedup_manifest.json matches exclusion pattern <pattern> "Deduplication completed" is then not printed.

Walkthrough

This PR updates CLI mode and scheduler handling, configuration and storage behavior, backup deduplication, logging, notification responses, and post-install audits. It also adds tests and updates related documentation.

Changes: CLI and scheduler workflows

Layer / File(s)	Summary
Config links and cron command parsing `cmd/proxsave/daemon_setup.go`, `cmd/proxsave/schedule_helpers.go`, `cmd/proxsave/runtime_helpers.go`, `cmd/proxsave/cron_indirect_refs.go`, `cmd/proxsave/backup_env_symlink_write_test.go`, `cmd/proxsave/system_cron_env_prefix_test.go`	Config-file symlinks are resolved for backup environment reads and writes. Cron command extraction steps over environment assignments. Schedule-adoption read failures now produce a warning with the failure reason.
Install and dry-run handling `cmd/proxsave/install_runtime.go`, `cmd/proxsave/install_step_abort.go`, `cmd/proxsave/install_tui.go`, `cmd/proxsave/main_modes.go`, `cmd/proxsave/main_config_modes.go`, `cmd/proxsave/install*test.go`, `cmd/proxsave/dryrun_ignored_modes_test.go`, `docs/CLI_REFERENCE.md`	The installer verifies cron write-back before removing a daemon unit. Closed TUI sessions are classified as install aborts. Dry-run compatibility checks reject specified modes, while `--upgrade-config --dry-run` runs the preview.
Decrypt workflow arguments and logging `cmd/proxsave/decrypt_cmd.go`, `cmd/proxsave/main_modes.go`, `cmd/proxsave/decrypt_log_level_test.go`	The decrypt workflow receives full CLI arguments and resolves the log level from arguments, config, and bootstrap settings.
Upgrade errors and exit handling `cmd/proxsave/upgrade.go`, `cmd/proxsave/main_update.go`, `cmd/proxsave/upgrade_*test.go`, `cmd/proxsave/config_helpers.go`, `cmd/proxsave/install.go`, `cmd/proxsave/main_footer.go`, `cmd/proxsave/footer_alias_test.go`, `docs/CLI_REFERENCE.md`, `internal/whatsnew/registry.go`	Upgrade handling distinguishes interruption, cancellation, and input abort. GitHub response excerpts are bounded and logged at DEBUG, while returned errors use status details. The command text removes the `proxmox-backup` alias.

Configuration and active secondary paths

Layer / File(s)	Summary
Config values and path defaults `internal/config/config.go`, `internal/config/templates/backup.env`, `internal/config/*test.go`, `docs/CONFIGURATION.md`, `docs/DAEMON.md`, `docs/CLOUD_STORAGE.md`, `internal/logging/bootstrap.go`, `internal/ui/shell/router.go`, `internal/ui/shell/session.go`, `cmd/proxsave/install.go`	Doubled dollar signs expand to literal dollar signs, and `USE_COLOR` controls color selection. The cloud log path default is relative. Documentation describes script paths and path handling.
Secondary paths and permission reporting `cmd/proxsave/permissions.go`, `cmd/proxsave/permissions_test.go`, `internal/security/security.go`, `internal/security/test.go`, `docs/CONFIGURATION.md`, `docs/SECURITY.md`	Secondary paths are active only when secondary storage is enabled. Permission finalization reports skipped paths, and security directory checks use active secondary paths.

Filesystem detection and cloud storage

Layer / File(s)	Summary
Filesystem and symlink detection `internal/storage/filesystem.go`, `internal/storage/storage.go`, `internal/storage/filesystem*test.go`, `cmd/proxsave/runtime_helpers.go`, `cmd/proxsave/filesystem_link_line_test.go`	Mount lookup uses device and resolved-path information. Filesystem results include symlink targets, and Ceph aliases are classified as network filesystems.
Cloud copy modes and rclone log redaction `internal/storage/cloud.go`, `internal/storage/cloud_*test.go`, `internal/orchestrator/storage_attempts_e2e_test.go`	Local cloud logs receive mode `0640`. Local backup copies on filesystems without ownership support use source modes or `0600`. Rclone flag values are redacted from copy errors.

Backup deduplication exclusions

Layer / File(s)	Summary
Exclude the manifest from deduplication `internal/backup/optimizations.go`, `internal/backup/dedup_manifest_excluded_test.go`	Deduplication is skipped when an exclusion pattern matches the dedup manifest or an ancestor.
Pass run exclusions into optimizations `internal/orchestrator/backup_run_helpers.go`, `internal/orchestrator/backup_run_phases.go`	The backup orchestrator passes collector exclusion patterns to the optimization configuration.

Log write gaps and log parsing

Layer / File(s)	Summary
Track incomplete log-file writes `internal/logging/logger.go`, `internal/logging/log_write_gap_test.go`	The logger records failed file writes, reports missing-line gaps, and exposes whether the log file is incomplete.
Parse long lines and retain logger counts `internal/orchestrator/log_parser.go`, `internal/orchestrator/extensions.go`, `internal/orchestrator/log_parser_long_line_test.go`, `internal/orchestrator/log_incomplete_counts_test.go`	Log parsing handles lines longer than 1 MiB. When the log file is incomplete, refreshed issue counts include the logger’s counters.

Notifications and email reporting

Layer / File(s)	Summary
PBS email lookup and mail queue counts `internal/notify/email.go`, `internal/notify/email_maillog.go`, `internal/notify/email_*test.go`, `docs/TROUBLESHOOTING.md`	PBS email lookup parses section-format `user.cfg` and distinguishes users without email. Mail queue counts use queue-ID lines when available.
Bound and redact notification response details `internal/notify/gotify.go`, `internal/notify/telegram.go`, `internal/notify/telegram_registration.go`, `internal/notify/webhook.go`, `internal/notify/*test.go`, `cmd/proxsave/telegram_server_status_body_test.go`	Notification errors omit or bound response bodies. Debug excerpts are bounded and redact applicable credentials. Webhook response reads are limited to 8 KiB.
Support email delivery outcomes `internal/support/support.go`, `internal/support/support_email_failure_line_test.go`	Support email failures and unexpected notifier outcomes produce a warning naming the recipient.

Post-install audit outcomes

Layer / File(s)	Summary
Validate post-install audit completion `internal/installer/audit.go`, `internal/installer/audit_incomplete_dryrun_test.go`	The audit collector checks for context cancellation and accepts only exit codes 0 and 1.
Display canceled audits as not checked `internal/ui/flows/install/audit.go`, `internal/ui/flows/install/audit_cancel_test.go`	The install UI records canceled collection errors and displays a “NOT CHECKED” result.

Full details: Title check

Explanation

The title "Release v0.46.1" names a release, but the changeset is a broad set of fixes across storage, notifications, webhooks, upgrades, config, installation, permissions, logging, and CLI behavior. The title only identifies the version bump and does not describe any of these changes. It is not off-topic, because the PR is the v0.46.1 release, and the whatsnew registry gains a 0.46.1 entry. It is also too general to tell a reader what changed.

Resolution

Retitle the PR to name the primary changes, for example by summarizing the main fixes (secret masking in logs and notifications, dry-run mode validation, symlink handling, and log write gap tracking) and keeping the version in the title, such as "Release v0.46.1: mask server responses and fix dry-run and symlink handling".

Full details: Docstring Coverage

Explanation

Docstring coverage is 74.58% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 59 functions across 50 files. (37 skipped: 6 unsupported, 31 over the file limit.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Handle quoted multiword assignments in system cron lines.

systemCronCommandToken returns the first word after a quoted, multiword assignment. For 0 2 * * * root MSG="nightly backup" /usr/local/bin/proxsave --backup, it returns MSG="nightly. Neither the direct nor the indirect detector matches that token, so the advisory omits this /etc job. The miss predates this PR. A fix must make cronCommandWord quote-aware, and root crontab removal also uses that function, so handle it as a separate change.

Record failed per-entry chown and chmod calls in the backup permissions outcome.

applyOwnershipWalkEntry logs a failed Lchown or Lchmod at debug level and returns nil. The walk therefore completes, and applyBackupPermissionsOutcome records nothing. When every entry fails and the directory passes the filesystem check, the footer prints "permissions and ownership normalized correctly (including backup paths)". Record failed entries in outcome.skipped, so the footer reports them.

When the run log misses lines, refreshLogIssuesFromFile raises ErrorCount from the logger. LogCategories is still built only from the file. A notification can therefore show an error count with no matching issue entry. The logger's issueLines holds the lost line, but no notification path reads it.

Assert the WARNING level for the unreadable backup.env case.

Require the DEBUG token on the answer line.

assertAnswerOnlyAtDebug checks that the answer reaches the log. It does not check the level of that line. The test loggers run at types.LogLevelDebug, so the buffer also holds INFO and WARNING lines. A sender that logs the answer at INFO or WARNING still passes every assertion. Each log line carries its level name (internal/logging/logger.go:509), so the helper can require DEBUG on each line that contains the answer.

Place the bot token before the proxy page in the personal Telegram fixture.

The fixture writes the bot token after proxyPage. In the 200-rune debug excerpt, only 56 of the 59 token characters appear, at runes 145 to 200. Redaction at telegram.go:634 is the only protection for this path. If that redaction is removed, the partial token still reaches the log, and the full-token assertion still passes.

Writing req.URL.Path first puts the complete token at runes 5 to 63. The 502 Bad Gateway</title> marker still ends within the window, at rune 118. A regression in the body redaction then fails the test.

Add a length bound on the server answer in the DEBUG line.

assertAnswerOnlyAtDebug does not check the excerpt length. Raising the Snippet(200) cap at a call site would still pass. Only the Telegram personal body exceeds 200 printable runes. Lengthen the centralized and Gotify response bodies past 200 runes so their caps are also exercised. Append the filler after the existing content, so the secret checks still cover the start of the excerpt.

In each subtest, take the rest of the answer line after that call site's DEBUG message prefix. For example, the personal prefix is Telegram: api answer (HTTP 502): and the Gotify prefix is Gotify answer (HTTP 502): . Count its runes with utf8.RuneCountInString and require at most 200. Do not anchor on <html>. The personal request path now precedes the body, so an <html> anchor drops it and undercounts. Use an upper bound, not exactly 200, because redaction can shorten the excerpt.

Cover cancellation at the upgrade confirmation prompt.

The interrupted during the check row cancels before release discovery, so it returns at upgrade.go:240-243. No test row reaches the prompt branch at upgrade.go:270-272. That branch returns exitCodeInterrupted when the context is canceled while the prompt waits. If the ctx.Err() case were removed, a canceled prompt would match input.ErrInputAborted at upgrade.go:273 and return types.ExitSuccess. The suite would still pass.

The prompt reads os.Stdin directly, so the test needs to replace stdin with an open pipe that carries no input. The case can then:

Serve a successful release response from the test server so release discovery completes.

Cancel the context while the prompt blocks on stdin.

Confirm the prompt was reached, for example by capturing the prompt text. This keeps a slow release check from cancelling in the earlier branch.

Assert exitCodeInterrupted and that no ERROR line is logged.

Add coverage for another user's email in the PBS user.cfg fixtures.

The new test covers two arrangements: a target with an email listed first, and a target without an email in a file that has no other users. A parser that ignores section ownership passes both cases. Add a case where another user's email precedes the target. Add a case where a target without email is followed by another user's email. The parser handles both correctly through its inTarget check, so this is a coverage gap and not a current defect.

Cover the running-dry-run cancel path in the audit test.

TestRunPostInstallAuditCancelledDryRunIsNotChecked returns context.Canceled from the auditCollect stub without waiting on ctx. No key reaches the running task. The test therefore covers only the NOT CHECKED mapping. It does not cover the path from an operator esc through RunTask into auditCollect.

The generic RunTask test covers esc wiring for a generic run function only. It does not show that the audit flow passes the cancelled context to auditCollect. Add a test in which the auditCollect stub blocks on ctx.Done(), the operator sends esc while the dry-run task runs, and the test asserts NOT CHECKED.

internal/notify/webhook_response_body_test.go: 1
85-87: Trivial · Stability & Availability · Quick win

Count bytes read from the response body in both large-response tests.

The webhook test checks only the log size. The webhook read at internal/notify/webhook.go:438 caps the body at webhookMaxResponseBytes (8 KiB). The DEBUG excerpt is capped at 200 printable runes by Snippet(200), not 200 bytes. Without the cap, the log stays under the limit, so the assertion still passes.

The personal Telegram send read at internal/notify/telegram.go:633 caps the body at 8192 bytes. The telegram personal case in internal/notify/server_answer_debug_test.go checks the error text and log content, not size. Removing the cap also leaves that test passing.

Asserting the (%d bytes read) value would also detect removal, but it reports the length after the cap. A counting reader measures bytes consumed from the body directly.

In each test, wrap the response body in a counting reader and assert the number read.

Webhook test: wrap the body through the notifier's client transport, then assert that the count equals webhookMaxResponseBytes.

Telegram personal case: wrap the body with io.TeeReader into a bytes.Buffer, then assert that the count equals 8192. The file must import bytes.

Review comments at @cmd/proxsave/install_runtime.go:
- Around line 105-106: Update the warning in the daemonUnitInstalled() branch to
avoid claiming that the daemon continues scheduling based only on the unit
file’s existence. Reword it to state that the service unit was left in place and
its running state is unverified; do not add an active-state check.
- Around line 102-104: Update the cron readback check around
canonicalCronLinePresent to verify the expected schedule and full command,
including --backup and configArgs, against the crontab entries. Only treat the
write as verified when that exact entry is present, and preserve the existing
safeguard that prevents daemon removal when verification fails.

Review comments at @cmd/proxsave/install_tui.go:
- Around line 303-305: Update the abort path around abortInstallOnOptionalStep
for “Healthcheck setup” so an aborted install after the daemon switch leaves
scheduler configuration consistent: either restore the previous scheduler state,
including the daemon unit and cron entry, or preserve the daemon configuration
when restoring backup.env.

Review comments at @internal/logging/logger.go:
- Around line 234-238: Update writeFileLocked so fileWriteGap is cleared only
after the missing-lines marker is actually written; preserve the pending gap
when a marker write times out or otherwise fails, allowing the next line to
retry it. Ensure writeOnceLocked’s result distinguishes a timed-out marker from
a successful write without treating the timeout as success.

Review comments at @internal/notify/email_maillog.go:
- Around line 230-232: Update the queue-ID condition in checkMailQueueFor to
require at least two fields before counting a line as a message, while retaining
the existing identifier match and counting behavior for valid queue headers.

Review comments at @internal/notify/email_queue_count_test.go:
- Around line 31-32: Update parseMailQueue to recognize Exim queue-ID tokens in
lines that begin with an age field, so this fixture counts one message instead
of falling back to counting address lines; change the corresponding assertion in
the test to expect 1.

Review comments at @internal/notify/email.go:
- Around line 731-732: Update detectRecipientViaPBSUserCfg to parse the property
key and value using any whitespace as the separator, including tabs, while
preserving the existing email-key and non-empty-value checks so the PBS user.cfg
fallback detects tab-separated email entries.

Review comments at @internal/notify/webhook.go:
- Around line 49-50: Update the query iteration in webhookBodyExcerpt to also
add each decoded query key to secrets, while preserving the existing addition of
query values, so echoed bare-query credentials are masked in the response
excerpt.
- Around line 61-62: Update webhookBodyExcerpt to mask any non-empty auth.Pass
in the response body before calling logging.RedactSecrets, ensuring short
passwords are covered while preserving the existing redaction of other secrets.

Review comments at @internal/orchestrator/log_parser.go:
- Line 143: Update forEachLogLine so leading whitespace does not count toward
logLineClassifyBytes; apply the 64 KiB classification limit to the line content
after that whitespace. Add a test confirming a WARNING or ERROR line following
more than 64 KiB of leading spaces is still classified.

Review comments at @internal/security/disabled_secondary_test.go:
- Around line 21-27: Set BaseDir to root in the test’s config.Config literal so
verifyDirectories creates identity paths within the temporary test root and the
test cleans them up.

Review comments at @internal/storage/cloud.go:
- Around line 566-569: Update rcloneFlagSecrets to track bare --flag tokens and
register the immediately following token as the credential value, even when that
value begins with --; preserve the existing handling of --flag=value tokens.
- Around line 524-527: Update the Rclone flag redaction flow around
rcloneFlagSecrets and logger.RegisterSecret so credential values shorter than
six characters are masked by their argument positions in both the debug argv log
and -vv stderr. Avoid globally replacing short values, which can redact
unrelated log text; preserve existing redaction for other secrets.
- Around line 273-275: Update setLocalModesFromSource to receive the
storeIssueRecorder used by setLocalPermissions, and record
StoreIssuePermissionsNotSet when safefs.Lchmod fails, matching the ownership
path’s failure handling. Pass the same recorder from the no-ownership branch so
Store reports the permission failure.
- Line 273: Path-based Lchmod can follow symlinks in parent directories; update
the local-cloud mode changes in setLocalModesFromSource and SetLocalLogMode to
resolve the destination safely and apply the mode only to the verified final
file. Ensure parent components cannot redirect resolution outside the cloud
directory during the operation.
- Line 1262: Update Store’s verification-failure path to call
setLocalPermissions with the same arguments when the failed verification leaves
a copied archive in c.localDir. Restrict the call to that retained-local-copy
case, preserving the existing permission logic for other paths.

Review comments at @internal/storage/filesystem_symlink_test.go:
- Around line 55-58: Canonicalize the temporary directory with
filepath.EvalSymlinks before the device comparison and direct detection, using
the resolved path when resolution succeeds. This ensures the direct result’s
LinkTarget check compares against the canonical target.

Review comments at @internal/storage/filesystem.go:
- Line 250: Update mountPointForDevice and its use in getFilesystemType to
verify that a selected mount alias resolves to the same device as the original
path before using it for Statfs or mount-type lookup. If the alias cannot be
validated, fall back to the original path so an overmounted or inaccessible
alias cannot produce an incorrect filesystem type or prevent detection.

Review comments at @internal/ui/flows/install/audit.go:
- Around line 87-90: Update the post-install audit result handling to recognize
cancellation in auditRes.CollectErr before the generic CollectErr failure case.
Log context.Canceled as a neutral informational outcome, while preserving the
existing skipped-by-user handling and warning for other collection errors.

Minor comments:
Review comments at @cmd/proxsave/cron_indirect_refs.go:
- Around line 2092-2094: Update systemCronCommandToken to handle quoted,
multiword assignments before extracting the command, so the example system cron
line identifies /usr/local/bin/proxsave rather than a word from the assignment.
Keep root crontab removal behavior and its use of cronCommandWord separate and
unchanged.

Review comments at @cmd/proxsave/permissions.go:
- Around line 144-146: Update applyOwnershipWalkEntry and the
applyBackupPermissionsOutcome flow so failed per-entry Lchown or Lchmod calls
are recorded in outcome.skipped instead of being silently treated as successful;
preserve the affected entry paths so the footer reports failures even when the
recursive walk completes without a directory-level error.

Review comments at @internal/orchestrator/extensions.go:
- Around line 342-348: Update refreshLogIssuesFromFile so that when the run log
is incomplete, it adds the logger’s issueLines to the notification’s
LogCategories alongside issues read from the file. Preserve existing
file-derived entries and avoid duplicating issues already represented there.

Nitpick comments:
Review comments at @cmd/proxsave/backup_env_symlink_write_test.go:
- Around line 65-72: Update the assertions in the test using
adoptSchedulerTimeForDaemon to verify that the log line containing “Backup
schedule: not adopted from cron entry” is emitted at WARNING level. Keep the
existing message-presence checks for the unreadable backup.env case.

Review comments at @cmd/proxsave/dryrun_ignored_modes_test.go:
- Around line 40-42: Add an explicit assertion in the accepted-mode test that
validateModeCompatibility returns no validation messages when UpgradeConfig and
DryRun are both true. Keep the existing substring-based guard check for other
accepted modes.

Review comments at @cmd/proxsave/upgrade_exit_codes_test.go:
- Around line 62-65: Extend the upgrade exit-code test around the `tc.cancel`
setup with a case that reaches the confirmation prompt before cancellation:
serve a successful release response, provide an open stdin pipe with no input,
and use captured prompt output to synchronize cancellation after the prompt is
reached. Assert the result is `exitCodeInterrupted` and no `ERROR` line is
logged, while preserving the existing pre-discovery cancellation case.

Review comments at @cmd/proxsave/upgrade_github_status_test.go:
- Around line 82-90: Extend the GitHub response fixture used by the test around
`Snippet(200)` in `upgrade_github_status_test.go` to exceed 200 runes, then
assert that the logged `response body=` excerpt contains no more than 200 runes.
Also add coverage for the API message bound near `Snippet(200)` in `upgrade.go`,
reusing the long fixture approach and verifying its logged excerpt respects the
same limit.

Review comments at @internal/backup/dedup_manifest_excluded_test.go:
- Around line 24-26: Add a nonmatching exclusion case to the table-driven test
so it verifies that dedup still creates symlinks when ExcludePatterns is
nonempty but does not match the manifest. Locate the test case table in the
dedup manifest exclusion test and include a pattern that cannot match the
manifest, expecting the symlink behavior to remain enabled.

Review comments at @internal/notify/email_pbs_usercfg_test.go:
- Around line 25-26: Add test coverage around detectRecipientViaPBSUserCfg for
section ownership: verify it returns the target’s email when another user’s
email appears first, and reports that the target has no email when another
user’s email follows its section. Keep the existing fixture assertions
unchanged.

Review comments at @internal/notify/server_answer_debug_test.go:
- Around line 28-30: Update assertAnswerOnlyAtDebug to inspect each log line
containing the answer and require that line to include the DEBUG level; preserve
the existing assertion that the answer appears in the log.
- Line 67: Update the personal Telegram fixture body in the test to place
req.URL.Path before proxyPage, keeping the long padding after both. Preserve the
existing debug-excerpt and redaction assertions so the test verifies the
complete token falls within the excerpt and remains redacted.
- Around line 28-40: Update assertAnswerOnlyAtDebug and its subtests to check
the answer excerpt after each site’s DEBUG message prefix, counting runes with
utf8.RuneCountInString and requiring no more than 200; do not anchor the count
on the HTML body. Extend the centralized and Gotify response bodies beyond 200
runes by appending filler after their existing content, so their snippet caps
are exercised while existing secret checks still cover the excerpt’s beginning.

Review comments at @internal/notify/webhook_response_body_test.go:
- Around line 85-87: Update the webhook response-body test to count bytes
consumed through the notifier client transport and assert the count reaches
webhookMaxResponseBytes. In the “telegram personal” case around sendToTelegram
and assertAnswerOnlyAtDebug, tee the response body into a bytes.Buffer and
assert that 8192 bytes were consumed; add the bytes import needed for the
counter.

Review comments at @internal/storage/cloud_local_test.go:
- Around line 663-665: Update TestCloudLocalFormNoOwnershipSetsTheSourceMode so
the source archive uses mode 0640 while both sidecars remain 0600; assert that
each destination retains its corresponding source mode.

Review comments at @internal/ui/flows/install/audit_cancel_test.go:
- Around line 16-17: Extend TestRunPostInstallAuditCancelledDryRunIsNotChecked
to cover cancellation during an active dry run: make the auditCollect stub wait
for ctx.Done() before returning, send esc while the task is running, and assert
the result is NOT CHECKED. Verify the audit flow passes the cancelled task
context through RunTask to auditCollect.

Compare the schedule and arguments in the readback, not only the command token.

The readback accepts any ProxSave cron line. When the crontab write is refused, an older line with a different configuration survives and passes the check. The daemon is then removed, and cron runs the old command. Compare the expected line, <schedule> <command> --backup<configArgs>, with the crontab entries before removing the daemon.

Do not claim the daemon keeps scheduling when only the unit file exists.

daemonUnitInstalled() checks only that the unit file exists. The unit can be stopped, disabled, or failed. This warning runs after the cron write fails, and cron mode does not start the daemon. Reword the warning, or check the unit's active state before stating that scheduling continues.

Roll back the scheduler change when an aborted install restores backup.env.

On abort after the daemon switch, backup.env reverts to SCHEDULER_MODE=cron. The daemon unit stays installed and running, and the cron entry stays removed. Restore the previous scheduler state, or keep the daemon configuration in backup.env.

Count Exim queue messages by queue ID, and expect 1 for this fixture.

The Exim fixture holds one message, but parseMailQueue returns 2 and the test asserts that value. Exim lines start with the age field (25m), which fails mailQueueIDLineRegex, so the parser falls back to counting address lines. Change the assertion to 1 and make the parser recognize the Exim queue-ID token. Without the parser change, the corrected assertion fails.

Split email property lines on any whitespace in the PBS user.cfg fallback.

detectRecipientViaPBSUserCfg splits each property line only on a space. The PBS section-config parser accepts any whitespace, so email<TAB>address is skipped. When the proxmox-backup-manager lookup fails, auto-detection reports no email, and relay or sendmail delivery is skipped.

Keep the gap when the marker write times out.

When a gap is pending, writeFileLocked writes a marker through writeOnceLocked. A timed-out marker returns as success, so the gap counter resets to 0 and the marker is never retried.

Mask decoded query keys in the response excerpt.

webhookBodyExcerpt adds query values from u.Query() but not their decoded keys. A bare query credential such as ?Bare%2FQueryToken42 therefore stays unmasked when an endpoint echoes Bare/QueryToken42 in an error body. With DEBUG logging, that decoded value reaches the log. Add the keys from u.Query() to secrets.

Resolve the cloud chmod through a trusted directory descriptor.

safefs.Lchmod (internal/safefs/safefs.go:305-316) applies O_NOFOLLOW only to the final path component. A symlink in a parent directory is still followed. On a local CLOUD_REMOTE share that another host can write to, a writer can plant such a symlink. The Stat check at cloud.go:48 and the Lchmod at cloud.go:273 then both resolve to the same file outside the share, and the process changes that file's mode. The target must already exist with the same basename as the backup file, which limits the impact. When ProxSave runs as non-root, the chmod affects only files the process user may change.

A check that refuses symlinked ancestors before the chmod does not close this window. A writer can swap a parent between the check and the chmod. Open the destination directory once, then resolve each component relative to that descriptor with O_NOFOLLOW. Call fchmod on the descriptor for the final file. Apply this to every Lchmod call on the local cloud path, including setLocalModesFromSource and SetLocalLogMode.

When the primary upload copies the archive to c.localDir but verification fails, Store keeps the copy and returns. setLocalPermissions runs only when the primary copy succeeds and the sidecar fails, or after a full success.

Check the device of the selected mount alias before using it.

When EvalSymlinks fails after Stat succeeds, mountPointForDevice returns the last mountinfo entry for the device, even if that alias does not hold the path. getFilesystemType then runs Statfs on that alias and reads its type from /proc/mounts by path, without checking the device. If that alias is overmounted by another filesystem, the reported type is wrong. If it is inaccessible, detection fails for a backup path that is accessible. Validate that the selected alias is on the stat device, or fall back to the original path, before reporting the filesystem.

Map a cancelled dry-run to a neutral message in the install flow.

When the operator cancels the post-install dry-run, the audit screen shows "NOT CHECKED". The install flow then logs "Post-install audit failed (non-blocking)" for the same run. Add a context.Canceled case before the CollectErr case so the install flow reports the cancellation as neutral.

Suggested fix

case !auditRes.Ran: bootstrap.Info("Post-install audit: skipped by user") + case errors.Is(auditRes.CollectErr, context.Canceled): + bootstrap.Info("Post-install audit: dry-run cancelled, nothing checked") case auditRes.CollectErr != nil: bootstrap.Warning("Post-install audit failed (non-blocking): %v", auditRes.CollectErr)

Review comment at @internal/ui/flows/install/audit.go around lines 87 - 90: Update the post-install audit result handling to recognize cancellation in auditRes.CollectErr before the generic CollectErr failure case. Log context.Canceled as a neutral informational outcome, while preserving the existing skipped-by-user handling and warning for other collection errors.

test(telegram): write the bidi rune of the startup test as an escape

2dc0ce2

d72453a put two raw U+202E runes in the test source (an editing tool turned the \u202e escape into the rune). Same string at run time; the source no longer holds an invisible reordering character.

style(upgrade): use errors.AsType for the GitHub status error

26f9010

Lint (modernize): errors.As with a declared target becomes errors.AsType in the two callers added by ed68c42, and the startup Telegram test ranges over strings.SplitSeq.

style(config): range over strings.SplitSeq in the template test

d16e280

Lint (modernize) on the test added by 61425db.

chore(whatsnew): add the 0.46.1 entry

c95ac3f

No new features since v0.46.0: the single generic fixes line.
