A 13-agent hunt pinned the "wird mit der Zeit laggy" symptom (CPU/RAM normal, UI
sluggish after many uploads) to the main process re-doing config I/O that scales
with the ever-growing history, stalling the synchronous main event loop so the
renderer's IPC round-trips feel laggy. The renderer render path was already
optimized (virtualized queue, capped panels) — confirmed clean.
This commit lands the two contained fixes (T1 + T3); the queue-persist rewrite (T2)
follows separately.
config-store (T1):
- load() now has an in-memory cache keyed on the file mtime+size. The processed
config (merged + credential-decrypted) is re-read/re-parsed/re-DPAPI-decrypted
ONLY when the file actually changes; our writes invalidate it, external edits
change mtime/size so the cache misses. Eliminates a full disk read + JSON.parse of
the whole growing history + per-credential decrypt on the vast majority of the ~38
load() call sites. load() always returns a structuredClone so callers can mutate
freely without corrupting the cache.
- _serializeForDisk clones ONLY the hosters subtree (the only thing encryptCredentials
touches) instead of JSON.parse(JSON.stringify(whole config)) — no more deep-cloning
an 8 MB history on every write.
- _atomicWrite refreshes the .bak with a raw fs.copyFileSync instead of
read + JSON.parse + write (it was re-parsing the full config a 2nd time per write).
main.js (T3):
- The log-flush paths resolved the log file via configStore.load() ~8x/second during
uploads (re-reading + cloning the whole config just to read logMode/logFilePath).
Cache those two strings in module scope, invalidate on the settings-save handlers.
Verified: 26 config-store tests (incl. new cache-correctness: independent clones,
external-change invalidation, save invalidation) + full 394-test suite green, lint 0
errors. Benchmark (8000-batch / 4.6 MB history): log flush no longer calls load() at
all; the remaining per-write history serialize is what T2 removes from the hot path.

Follow-up hardening on the v3.3.80 queue-persistence fix after a deeper adversarial
sweep + reviewer pass over the WHOLE subsystem (not just the diff). Two real defects:
1. Basename-collision lost work (regression introduced by v3.3.80 FIX A).
restoreQueueStateFromConfig collapses jobs on the FULL path while the ts-gate keys
on basename|hoster. Two genuinely different files with the same basename queued to
the same hoster from different folders therefore share a gate key: if one was logged
after savedAt, the ts-rule dropped BOTH — silently losing the still-pending one.
Pre-FIX-A only 'done' jobs were dropped, so a pending file was never at risk.
Fix: an ambiguity guard in partitionRestoredJobsByLog — the ts-rule is suppressed
when a basename|hoster key maps to more than one distinct file path (the log records
only basenames, so it can't say which physical file completed). The done-in-log rule
is unchanged. Fails safe: worst case a visible ghost survives, never silent data loss.
2. selectedFiles re-materialization with removeFromQueueOnDone=ON (second mechanism,
independent of the stale snapshot). When that setting is on, a completed job is
stripped from queueJobs but its path stays in selectedFiles (syncSelectedFilesFromQueue
only runs at batch-done, never on a mid-upload close). On restart the ts-gate operates
on queueJobs and never sees it, then the startup updateUploadView -> buildQueuePreview
re-creates it as a preview ghost AFTER the gate ran, and it re-persists with a fresh
savedAt — sticky. Fix: completedSelectionKeys() seeds _completedUploadKeys (the set
buildQueuePreview already consults) from the log at startup, keyed on full path, with
the same ambiguity guard. Log-based so it survives a hard kill, consistent with FIX A.
Also extracts the orphan-tmp sweep decision into lib/orphan-tmp.js (was untested inline
code in main.js; behavior-preserving) and adds executable coverage for the paths that
were previously only argued from logic: orphan-tmp sweep, config-store pendingQueue+savedAt
round-trip, an end-to-end scenario in the exact user-reported shape (300 queued / ~200
finished mid-session), and a 3000+500-iteration property fuzz of the gate invariant
including the lost-work guarantee. 359/359 green, ESLint clean, smoke-boot unchanged.

The byse suspect size-memo (softened in v3.3.73 to arm only after two
confirmed suspect rejections on the same account and only for strictly
larger files) still occasionally pre-skips a primary account with
"Bekanntes Größen-Limit auf diesem Account", which the user finds annoying
when they would rather just let every file attempt the upload for real.
Add a per-hoster opt-out: a new "Größen-Limit merken" checkbox (Accounts tab,
default ON so existing behavior is preserved for everyone) that, when
unchecked, disables the memo-based pre-skip entirely for that hoster.
- config-store.js / upload-manager.js DEFAULT_SETTINGS: sizeMemoEnabled: true.
- upload-manager.js _suspectMemoBlocks(): returns false up front when the
hoster has sizeMemoEnabled === false. That single guard covers BOTH consult
sites — the pre-job block (skips the guaranteed-fail upload) and the
alternate-account skip — since both route through _suspectMemoBlocks. The
memo is still recorded; it is simply never allowed to block. This moves the
flow toward "fail open": with the toggle off, every file always gets a real
attempt on its account.
- The genuine suspect-reject alternates walk is gated on err.suspectReject,
not the memo, so disabling the memo does not weaken real failover — a file
the account actually rejects still rolls over to the next account.
- renderer/app.js: checkbox data-hs="sizeMemoEnabled", checked when
hs.sizeMemoEnabled !== false; persisted by the existing generic checkbox
path in saveHosterSettingsFromDom(). The running manager picks it up on the
next batch (fresh UploadManager) and immediately on save (updateSettings).
Tests: suspect-reject-alternates gains a disabled-memo case proving the larger
third file still gets a real primary attempt (key1 tried 3x, no
suspect-memo-skip event); config-store gains a default-true + persist-false
case. Full suite 305/305. Reviewed by a 4-lens adversarial workflow
(completeness / composition / persistence-ui / conventions): 0 findings.

v3.3.74 created a fresh account picker inside every buildUploadTasks /
buildUploadTasksFromJobs call, so its in-memory rotation index reset to 0
on each call. That is correct for a one-shot batch (drag-drop N files at
once distributes fine), but it silently no-ops in exactly the pattern the
byse 80-uploads/30-days quota cares about: the folder monitor feeds new
files into a *running* batch one detection at a time via add-jobs-to-batch
(renderer -> add-jobs-to-batch IPC), and per-detection autoStart likewise
fires start-upload per file. Each of those calls rebuilt the picker from
index 0, so account 1 won every single time and the secondary accounts
never received anything.
The rotation cursor now lives outside the picker and survives across calls
and across app restarts (the quota spans a rolling 30-day window, so a
session-only counter would still starve secondaries for users who restart
between small uploads):
- account-rotation.js: createAccountPicker() accepts a seed { indices } map,
resumes the per-hoster cursor from it, and exposes indices() (the advanced
cursors) + dirty() (whether any rotation actually happened this call). The
cursor is a monotonic counter taken mod the current enabled-account count,
so it keeps wrapping correctly even if an account is later enabled/disabled.
- config-store.js: new top-level rotationCursors map (added to DEFAULTS, read
back in load() which otherwise reconstructs the result and would drop
unknown keys) plus a saveRotationCursors() method. The existing
read-modify-write save() preserves it across unrelated settings/credential
saves; secret-store never touches it.
- main.js: a module-level _rotationCursors is the authoritative source of
truth (seeded once from disk on first use, updated synchronously per batch),
with config as restart-survival backing. makeAccountPicker() seeds the
picker from it; persistRotation() folds the advance back and flushes to
config only when dirty. Authoritative in-memory state also closes the
disk-read race two rapid batches would otherwise hit. Both task builders
now receive the picker instead of constructing their own.
Composition with failover is unchanged and verified: the picker only chooses
each file's *initial* account and is never called on the failover path. The
pre-job-swap reroutes a task only when that task's own account is in
_failedAccounts, so a dead account's jobs reroute while healthy accounts keep
their rotation share. No double-advance of the cursor.
Tests: account-rotation gains seeded-resume, drip-feed-across-pickers (the
regression), dirty()-semantics, carry-forward, and count-shrink-wrap cases;
config-store gains rotationCursors default, save round-trip, no-clobber, and
credentials-undisturbed cases. Full suite 303/303.

Adds a third choice next to the existing single-file and per-day modes: a new
log file is created at every app start (process boot) and used until the app is
closed. A close → reopen of the app starts a new session, hence a new file.
File pattern: fileuploader-session-YYYY-MM-DD_HH-MM-SS-<pid>.log.
The boolean sessionLog field — misnamed: it actually toggled daily mode — is
replaced by a logMode enum: "single" | "daily" | "session". The misnomer made
the migration the trap to watch: existing users with sessionLog:true must land
on "daily", NOT "session". normalizeLogMode handles this and is unit-tested.
- lib/log-mode.js (new, pure, dual CJS/window export): normalizeLogMode +
resolveLogFileName + format helpers. No fs, no Date.now() at call time.
- config-store.js: normalize at the single load() boundary so downstream
readers consume logMode only. logMode is deliberately NOT seeded in DEFAULTS
(would beat the legacy migration after merge).
- main.js: stamp SESSION_ID once at process start (with pid hedge against
same-second restart collisions); getLogFilePath and buildFallbackLogName
switch on mode via the lib. _resolveUploadLogTarget cache key is now just
the primary path, which already encodes mode/date/session — self-invalidates.
- renderer: <select> with three German labels replaces the old checkbox;
saveSettings writes logMode; index.html loads the lib so window.LogMode is
available in renderSettings.
- Tests: 14 log-mode tests (incl. legacy-migration regression), 3 config-store
tests (defaults, legacy migration, round-trip all three values). 200/200.
End-to-end simulated locally: two launches → two distinct session files; PID
hedge produces distinct names even within the same second.

New per-hoster setting "Links in Log schreiben" (logToFile, default
on). When unchecked for a hoster, that hoster's successful upload
links are no longer written to fileuploader.log — other hosters keep
logging independently.
- lib/config-store.js: logToFile: true added to HOSTER_SETTINGS_DEFAULTS;
merge-on-load gives every hoster the key (old configs included).
- renderer/app.js: checkbox per hoster panel + collection loop now
handles type=checkbox (boolean) alongside the numeric fields. The
autosave bind already special-cased checkboxes (change event).
- lib/log-policy.js (new): hosterLogToFileEnabled() — pure, opt-out
semantics. Only an explicit logToFile===false disables; missing/
malformed/non-true values all default ON so links are never
silently dropped.
- main.js: shouldLogHosterToFile() reads the LIVE uploadManager
.hosterSettings (so a mid-batch toggle takes effect at once), falls
back to persisted config, then to enabled. Guards appendUploadLog
in the done handler; skipped writes get a debugLog line.
Tests: 8 log-policy (defaults, opt-out, per-hoster independence,
malformed input) + 2 config-store (default true, persisted false
survives reload). 147/147 green, eslint clean.
- Fix 3 failing config-store tests: update expectations to match
multi-account array format (tests passed with old single-object format)
- backup-crypto: reject empty/null passwords on encrypt+decrypt
instead of producing weak keys silently
- updater: validate assetUrl and assetName before downloading
to prevent crash on incomplete update metadata
All 59 tests now passing.
