* 🐛 Fix library updates reappear after file is reloaded
Summary
Migrate synced_at timestamps to a standalone file_library_sync table to ensure sync state is tracked for both direct and transitive libraries.
Problem
Transitive libraries (libraries imported by other libraries) are not stored as direct rows in file_library_rel. Because the system previously coupled synced_at directly to the file_library_rel schema, transitive libraries lacked a persistent location for their sync timestamps. This caused sync states to be lost or incorrectly reported for nested dependencies.
Changes
Schema Migration: Created file_library_sync and migrated existing synced_at values from file_library_rel.
Decoupling: Removed tight Foreign Key coupling to allow sync rows to exist independently of specific relationship records.
Persistent Writes: Added upsert-file-library-sync! helper. Updated all import, duplication, and RPC write paths (v1/v2/v3 importers, link-file-library) to ensure every write persists a sync row.
Unified Reads: Updated both direct and recursive/transitive library queries to fetch synced_at from the new table.
Testing: Added regression tests to verify that sync rows are correctly created/updated even when a transitive relation is absent in file_library_rel.
Impact
This fix ensures that the system accurately records and retrieves sync states for the entire library dependency tree, resolving the bug where nested libraries appeared out of sync.
* ✨ MR review
The recursive `read-items` function in `app.util.sse/read-stream`
caused a synchronous stack overflow when reading buffered stream
data. Each `rx/mapcat` call chained another recursive invocation
on the same call stack without yielding to the event loop.
Replace the recursive pattern with an `rx/create`-based async pump
that uses Promise `.then()` chaining, keeping the call stack depth
constant regardless of stream size.
Also add progress reporting with names and IDs during binfile
export and import, and bump `eventsource-parser` dependency.
Closes#9470

The current binfile export process uses a streaming technique. The
major problem with the streaming approach is the case when an error
happens on the middle of generation, because we have no way to
notify the user about the error (because the response is already
is sent and contents are streaming directly to the user
client/browser).
This commit replaces the streaming with temporal files and SSE
encoded response for emit the export progress events; once the
exportation is finished, a temporal uri to the exported artifact
is emited to the user via "end" event and the frontend code
will automatically trigger the download.
Using the SSE approach removes possible transport timeouts on export
large files by sending progress data over the open connection.
This commit also removes obsolete code related to old binfile
formats.
Caused when file is deleted in the middle of an exportation. The
current export process is not transactional, and on file deletion
several queries can start return not-found exception because of
concurrent file deletion.
With the changes on this PR we allow query deleted files internally
on the exportation process and make it resilent to possible
concurrent deletion.
Replace general usage of virtual threads with platform threads
and use virtual threads for lightweight procs such that websocket
connections. This decision is made mainly because virtual threads
does not appear on thread dumps in an easy way so debugging issues
becomes very difficult.
The threads requirement of penpot for serving http requests
is not very big so having so this decision does not really affects
the resource usage.
We don't migrate the libraries for avoid cascade migration; it is not ideal
but it reduces the total of the required memory needed for process a single
file migration that requires libraries to be loaded.
The patch was already existed but only applied to binfile-v3,
with this commit, the fix is properly applied to all binfile
formats and for duplicate file operation.
