📝 WalkthroughWalkthroughThe pull request adds a managed update system with validated manifests, optimized ranged downloads, filesystem transactions, startup recovery, Electron RPC procedures, and frontend download integration. Game launches wait for update recovery, and managed updates use transactional setup and completion. ChangesManaged update system

Mergeability Score: 🟠 High · up to The new managed-update and recovery flows still contain high-impact issues: malformed recovery data can block game launches, transaction identifiers can enable unsafe filesystem paths, rollback checks can underestimate required disk space, and large or slow updates can stall the application or fall back unexpectedly. The PR is not merge-ready until these risks are fixed or explicitly accepted. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Greptile SummaryThe PR adds managed direct-download updates that reuse verified installed files, retrieve validated ZIP ranges, stage addon setup in recoverable transactions, and fall back to full downloads when optimization is unavailable.
Confidence Score: 3/5The PR should not merge until incomplete transaction directories are recoverable and archive-controlled central-directory allocations are bounded. A crash before the initial transaction journal write can permanently block game launches, and a malformed downloaded ZIP can exhaust process memory while its managed manifest is built. Files Needing Attention: application/src/electron/update-system/transaction.ts, application/src/electron/update-system/zip.ts
|
| Filename | Overview |
|---|---|
| application/src/electron/update-system/transaction.ts | Adds the recovery transaction state machine, but an interruption before the first journal write can make startup recovery permanently block guarded operations. |
| application/src/electron/update-system/zip.ts | Adds local ZIP manifest parsing with path and format checks, but trusts the declared central-directory allocation size. |
| application/src/electron/update-system/remote.ts | Adds bounded ranged retrieval, source verification, ZIP-structure checks, reuse hashing, and output hash validation with fallback on failure. |
| application/src/electron/update-system/manager.ts | Coordinates optimized and full managed extraction plus transaction RPC operations; its ZIP manifest path exposes the unbounded parser allocation. |
| application/src/frontend/managers/DownloadManager.svelte | Integrates begin, setup, finish, library finalization, completion, and rollback for managed updates with explicit error handling. |
| application/src/electron/update-system/readiness.ts | Gates update and launch operations on recovery, which makes an unhandled recovery artifact failure globally blocking. |

### Issue 1
application/src/electron/update-system/transaction.ts:404
**Incomplete journals block recovery**
When the application exits after creating a transaction directory but before writing its journal, `recoverTransaction` fails immediately at `readJournal`. That failure is retained globally, causing every operation guarded by `afterUpdateRecovery`, including game launches, to fail on every restart until the incomplete directory is manually removed.
### Issue 2
application/src/electron/update-system/zip.ts:76
**Archive metadata drives allocation**
When a downloaded ZIP declares a very large non-ZIP64 central-directory size, the parser passes that archive-controlled value directly to `readExactly` without bounding it against the file size or a safe maximum, causing a multi-gigabyte allocation that can exhaust memory or terminate Electron.
**How this was verified:** The EOCD-derived `centralSize` flows directly to `readExactly` after checks that reject sentinel values but impose no allocation bound.
### Issue 3
application/src/electron/update-system/files.ts:79
**Filesystem writes bypass Bun convention**
The new update subsystem uses `node:fs` `readFile` and `writeFile` operations here and in the staging, remote, and transaction modules instead of the repository-preferred `Bun.file` API. Consolidating these persistence paths on the required runtime convention avoids maintaining parallel filesystem patterns.

- Around line 69-79: Replace the synchronous gzipSync call in the
Effect.tryPromise request body with asynchronous gzip compression using
node:zlib/promises or a promisified node:zlib.gzip, await the result inside the
try callback, and preserve the existing manifest payload and fetch behavior.
- Around line 33-52: Update the response-body handling around the manifest fetch
to read response.body incrementally and stop once accumulated bytes exceed
maximumManifestBytes, avoiding response.text() and unbounded buffering; preserve
the existing size validation and parsing behavior. Also replace the nested
Effect.runPromise used for UpdateManifestSchema decoding with an
Effect.flatMap-based composition so decoding remains in the surrounding Effect
and preserves interruption.

manifest generation is best-effort: preserve the successfully extracted staging
directory when manifest creation fails and return a result with an absent
manifest instead of failing the operation. Remove the manifest-build error
cleanup that deletes extracted content, adjust the result type and
submitCommunityManifest call as needed, and update callers such as
beginManagedSetup to explicitly handle the missing manifest.

the existing installedByHash behavior while avoiding repeated linear scans at
all three sites.
In `@application/src/electron/update-system/remote.ts`:
- Around line 323-343: Update the range-download attempt in the
Effect.tryPromise block to avoid applying the 7.5-second total sourceTimeoutMs
deadline to the response body; use an idle timeout that resets whenever a chunk
arrives and is cleared when the pipeline settles, while retaining
sourceTimeoutMs for HEAD and structural probe requests.
- Around line 237-252: In the central-directory loop, update the bounds
validation before any field reads so offset + 46 must be within central.length;
return false immediately when the fixed header is truncated. Keep the existing
end, disk, and flags validation after parsing the header fields.
- Around line 359-420: Update extractEntry so compressed is created only after
local-header validation and dataOffset checks complete; ensure the stream is
destroyed in a finally block covering the pipeline, and remove the partial
destination file when pipeline processing fails, while preserving existing
hash/size cleanup and return behavior.
In `@application/src/electron/update-system/staging.ts`:
- Around line 109-124: Update findMarker to catch JSON parsing and marker file
read errors for each candidate entry, skip unreadable or corrupt markers, and
continue scanning the remaining .json files; preserve returning the first valid
marker matching path and registryPath, otherwise return undefined.
In `@application/src/electron/update-system/transaction.ts`:
- Around line 386-400: Add a TransactionJournalSchema and decode parsed journal
data within readJournal, ensuring malformed or incomplete journal.json files
return typed errors instead of reaching rollbackTransaction as invalid data.
Update recoverTransactions to handle failures independently for each
recoverTransaction call so one corrupt transaction does not abort recovery of
other directories or gate later operations.
- Around line 118-148: Update the rollback-space calculation near filesToProtect
and requiredBackupBytes so it estimates the sizes of the same existing files
that the backup loop actually copies, including unmanaged files and the
ownership-undefined case. Alternatively, if retaining the ownership-aware
estimate, filter filesToProtect to exactly that same set; ensure the
availability check and backup operation use matching file sets.
In `@application/src/electron/update-system/zip.ts`:
- Around line 39-48: Update readExactly to repeatedly read into the remaining
portion of the buffer, advancing the file position and accumulated byte count
after each read; only throw “Unexpected end of ZIP archive” when a read returns
zero before length bytes are collected, then return the fully populated buffer.
- Around line 84-129: In the ZIP entry parsing loop, reject entries whose
compressedSize, size, or localOffset equals 0xffffffff, since ZIP64 extra-field
values are not supported. After calculating each entry’s dataStart, validate
that dataStart plus compressedSize does not exceed stat.size before adding the
entry, using the existing parsed entry fields and bounds-checking flow.
- Around line 168-200: In buildZipManifest, validate the constructed manifest
with UpdateManifestSchema before returning it, and convert any schema validation
failure into FileSystemError. Return the validated manifest so manager.ts
submits only schema-compliant data to submitCommunityManifest; retain the
existing literal fields without adding a cast.
In `@application/src/frontend/lib/downloads/services/DirectService.ts`:
- Around line 97-121: In
application/src/frontend/lib/downloads/services/DirectService.ts:97-121, update
the optimized branch so the inserted managed-update record is guaranteed to
transition from downloading to setup-complete or error, and ensure the
ddl:download-complete listener is registered before insertion. In
application/src/frontend/components/PlayPage.svelte:114-114, report a blocked
launch to the user instead of returning silently when a non-terminal update
record is detected.
In `@application/tests/update-system.test.ts`:
- Around line 101-118: Split the test around isStructurallyValidManifest into
two independent invalid manifests: one changing only the second entry’s path to
match the first, and another changing only its range to be out of source bounds.
Decode each separately and assert that both results are Left.
---
Nitpick comments:
In `@application/src/electron/handlers/handler.update-system.ts`:
- Around line 22-24: Update the startUpdateRecovery call to run
recoverTransactions and recoverStaging independently, ensuring staging recovery
executes even when transaction recovery fails while preserving each recovery
step’s failure handling.
In `@application/src/electron/update-system/community.ts`:
- Around line 14-17: Update endpoint() to parse the trimmed
OGI_UPDATE_MANIFEST_URL with URL, return its normalized value only when parsing
succeeds and the protocol is exactly https:, and return undefined for malformed
or non-HTTPS values.
In `@application/src/electron/update-system/files.ts`:
- Around line 76-84: Update writeJsonAtomic to fsync the temporary file before
renaming it, then fsync the containing directory after the rename so the durable
replacement is persisted. Wrap the write/rename sequence in cleanup handling
that removes the generated .tmp file when any step fails, while preserving the
existing atomic JSON-write behavior.
In `@application/src/electron/update-system/manager.ts`:
- Around line 220-240: Update inspectRemoteSource to use a shared HEAD probe
timeout constant instead of the hardcoded 3,000 ms value, consolidating the
related timeout definitions across the update-system modules while preserving
the existing timeout behavior.
- Around line 88-94: Update the Effect.catchAll handler in the staging/update
flow to log a warning with the failure details before returning the existing
fallback result. Follow the warning pattern used by the remote update flow,
covering failures from registerStaging or removeStaging without changing the
fallback behavior.
- Around line 160-203: Extract a shared decodeManifest helper for
UpdateManifestSchema decoding and its existing Invalid update manifest error
mapping, then reuse it in beginManagedSetup and finishManagedSetup while
preserving their transaction-specific error mapping. Remove the unnecessary
manifest as UpdateManifest casts from prepareTransaction and commitTransaction
calls; use the decoded manifest directly.
In `@application/src/electron/update-system/model.ts`:
- Around line 111-117: Update isSafeRelativePath to reject any path segment
containing a colon and reject Windows reserved device-name segments, including
reserved names with extensions or trailing spaces/dots and the COM/LPT numbered
forms. Preserve the existing traversal, absolute-path, null-byte, backslash, and
.ogi-update-ranges checks.
In `@application/src/electron/update-system/planner.ts`:
- Around line 71-101: Consolidate the duplicated grouping logic by exporting the
existing coalescing helper from remote.ts and reusing it in
measureCoalescedRanges and the downloader, passing the configured
coalesceGapBytes value so planning and requests use identical boundaries. In
measureCoalescedRanges, reset end when starting a new group to make each range
independent while preserving the existing sorted-range behavior.
In `@application/src/electron/update-system/readiness.ts`:
- Around line 10-34: Update startUpdateRecovery and afterUpdateRecovery so
recovery failures are logged through the existing main-process logger and
callers do not remain permanently blocked by a single failed attempt; provide an
explicit retry path that resets the started and recoveryFailure state before
rerunning recovery, while preserving the successful recovery flow. Also ensure
afterUpdateRecovery handles a recovery that was never started with a bounded
failure or diagnostic instead of waiting indefinitely, and retain the existing
failure propagation for callers.
In `@application/src/electron/update-system/remote.ts`:
- Around line 102-120: Update the range-group processing around fetchRange and
extractEntry to use bounded concurrency, such as Effect.forEach with a small
concurrency limit, so multiple groups can download simultaneously without
exceeding resource limits. Preserve sequential extraction and cleanup within
each group, including its existing entry order and failure behavior.
In `@application/src/electron/update-system/staging.ts`:
- Around line 36-49: Update registerStaging so cleanup only removes the staging
directory when this invocation created it; track whether path existed before
fs.mkdir and skip recursive removal for pre-existing directories, while
preserving cleanup for newly created directories and propagating the original
failure.
In `@application/src/electron/update-system/transaction.ts`:
- Around line 490-498: Refactor cleanupPreparation to compose
removeStaging(extractedPath) directly with the filesystem cleanup effect instead
of calling Effect.runPromise inside Effect.promise. Preserve the sequential
order: remove directory first, then run removeStaging within the same Effect
runtime so interruption and tracing propagate.
In `@application/src/frontend/lib/downloads/services/DirectService.ts`:
- Around line 94-96: Update the Effect.catchAll fallback in DirectService to log
the caught failure before returning the fallback result. Preserve the existing {
kind: 'fallback' } behavior while ensuring manifest validation failures and RPC
faults include their cause in the diagnostic log.
In `@application/src/frontend/store.svelte.ts`:
- Line 15: Update the UpdateManifest import in store.svelte.ts to use the
consistent .js module specifier style established by electron-rpc.ts, while
preserving the existing imported symbol and type-only import.

Validate transactionId before path joins.
completeSetup and abortSetup use Schema.String, so path traversal strings reach journalPath and the recursive transaction-directory removal. Constrain transactionId to the canonical UUID format produced by randomUUID. Also validate the journal before using its path fields.

The size limit does not prevent unbounded buffering.
Line 34 reads content-length, but the check only applies when the header is present and truthful. Line 41 then calls response.text(), which buffers the complete body into memory. The check at line 42 runs after the allocation. A server that omits content-length or under-reports it can therefore exhaust main-process memory before any limit applies.
Read the body in chunks from response.body and stop once the accumulated size passes maximumManifestBytes.
Separately, line 48 calls Effect.runPromise inside Effect.tryPromise. That detaches the decode from the surrounding fiber and drops interruption. Return the parsed value and decode with Effect.flatMap instead.
🔧 Proposed fix for the buffering limit
- const text = await response.text();
- if (Buffer.byteLength(text) > maximumManifestBytes) return undefined;
+ if (!response.body) return undefined;
+ const chunks: Buffer[] = [];
+ let total = 0;
+ for await (const chunk of response.body as AsyncIterable<Uint8Array>) {
+ total += chunk.byteLength;
+ if (total > maximumManifestBytes) return undefined;
+ chunks.push(Buffer.from(chunk));
+ }
+ const text = Buffer.concat(chunks).toString('utf8');

Update the response-body handling around the manifest fetch to read
response.body incrementally and stop once accumulated bytes exceed
maximumManifestBytes, avoiding response.text() and unbounded buffering; preserve
the existing size validation and parsing behavior. Also replace the nested
Effect.runPromise used for UpdateManifestSchema decoding with an

gzipSync blocks the Electron main process.
gzipSync compresses on the calling thread. UpdateManifestSchema allows up to 250,000 entries, so a canonical manifest can reach tens of megabytes. Compressing that synchronously freezes the main process and the UI for a noticeable time, and this submission is best-effort work that the user does not wait for.
Use the async zlib.gzip (via node:util promisify or node:zlib/promises) inside the tryPromise body.
🔧 Proposed fix
-import { gzipSync } from 'node:zlib';
+import { promisify } from 'node:util';
+import { gzip } from 'node:zlib';
+
+const gzipAsync = promisify(gzip);

Hashing spawns one worker thread per batch of 8 files. hashFiles creates a new Worker on every invocation, and both callers loop over their input in batches of 8. A large installation or archive therefore creates thousands of short-lived worker threads, each compiling the eval'd worker source. The shared root cause is the per-call worker lifetime, not the batch size.

Loop until the requested length is read.
handle.read can return fewer bytes than requested for a regular file. readExactly treats any short read as a corrupt archive, so a valid ZIP with a large central directory can be rejected. Read in a loop until length bytes arrive or EOF is reached.

Reject per-entry ZIP64 sentinel values and check entry bounds.
The EOCD check rejects archive-level ZIP64 markers, but per-entry ZIP64 is still accepted. A ZIP64 entry stores 0xffffffff in compressedSize, size, or localOffset and keeps the real values in the extra field, which this parser ignores. The manifest then records a wrong range, and the entry data is never bounded against stat.size.
Reject those sentinel values and verify that dataStart + compressedSize <= stat.size.

FileSystemError. Return the validated manifest so manager.ts submits only
schema-compliant data to submitCommunityManifest; retain the existing literal
fields without adding a cast.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
A managed-update record that never reaches a terminal status blocks the launch permanently. The optimized branch inserts the download record with status: 'downloading', and PlayPage.svelte now treats every non-terminal update record as an active update download that blocks the launch. One shared root cause links both sites: the record lifecycle has no guaranteed terminal state.
application/src/frontend/lib/downloads/services/DirectService.ts#L97-L121: guarantee that the inserted record always reachessetup-completeorerror, and confirm that theddl:download-completelistener is registered before the record is inserted.application/src/frontend/components/PlayPage.svelte#L114-L114: report the blocked launch to the user instead of returning with no output, so a stuck record is visible.

Split this test so each rejection rule is exercised separately.
The invalid manifest combines a duplicate path and an out-of-source range. The decode produces one Left, so the assertion passes if either rule fires. If the duplicate-path check in isStructurallyValidManifest regressed, this test would still pass because the range check fails first.
Decode two separate manifests: one with only a duplicate path, one with only an out-of-source range.

Description
Adds managed direct-download game updates that reuse unchanged owned files when worthwhile, validate community manifests, and fall back to the existing full-update path when optimization is unavailable. Setup changes are applied through recoverable transactions so interrupted or failed updates can roll back safely.
Example
For an update where most archive data is unchanged, OpenGameInstaller now reuses verified installed files, downloads only required archive ranges, runs addon setup in a staged transaction, validates the resulting library metadata, and commits atomically.
