SrvStateManager for the stand-alone HTTP server.

The server serves a fixed set of libraries known at startup. Each one is parsed once in the constructor, an in-memory SearchContext is built for it, and the (BibDatabaseContext, mtime) pair is held for the lifetime of the process.

Because nothing watches the files asynchronously (jabsrv uses DummyFileUpdateMonitor everywhere), getOpenDatabases does a per-call stat on every tracked file and re-parses any that changed on disk since the last observation. The cost is one stat per library per request; only an actual modification triggers re-parsing. This is the cheap middle ground between "snapshot at startup" (broken when the user edits a .bib externally) and running a real org.jabref.model.util.FileUpdateMonitor thread.

There is no Postgres path: the in-memory backend has no startup cost, and the toggle is hardwired to false.

public synchronized ObservableList<BibDatabaseContext> getOpenDatabases()

Implements org.jabref.http.SrvStateManager.getOpenDatabases.

Returns an unmodifiable snapshot of the open libraries.

Grizzly/Jersey serve requests concurrently and several resources call getOpenDatabases().stream(). Returning the live openDatabases would let a caller iterate the list while another thread enters this method and refreshStaleLibraries structurally modifies it via the ListIterator#set in the reparse path. The snapshot is taken under the monitor so iteration after the call is race-free.

parseLibraryback to summary
private Optional<BibDatabaseContext> parseLibrary(Path file)

Parses a single library. A library that fails to parse is logged and skipped.

refreshStaleLibrariesback to summary
private void refreshStaleLibraries()

Compares each tracked file's current mtime against the snapshot taken at the last parse. If it changed, the library is re-parsed, the context in openDatabases is replaced, the old SearchContext is removed, and a fresh one is registered under the new context's uid.
