SearchIndexer..::..Dispose Method
Assembly: AdvantageCSP.Keyoti.SiteIndexer (in AdvantageCSP.Keyoti.SiteIndexer.dll)
Remarks
Do not copy this shape. The host holds the plug-in in a field typed SearchIndexPluginBase and calls Dispose() on it; that method is not virtual, so the call binds statically to the base and this body never executes. The practical consequence is that ExtendedParserProvider — and with it the browser session it owns — is never released by the host's teardown.
The extension point that does get reached is Dispose(bool): the base's public Dispose() calls it, and it is virtual. Override that instead, and always chain to base.Dispose(disposing) — the base implementation is what unsubscribes the dispatcher handlers. Because the host constructs one plug-in instance per domain in a loop over the whole run, a missed unsubscribe leaves the dispatcher holding every previous domain's plug-in, browser session and link sets alive for the lifetime of the process.
Examples
protected override void Dispose(bool disposing) { if (disposing) { try { if (_parserProvider != null) _parserProvider.Dispose(); } catch { /* teardown must not throw */ } _parserProvider = null; } base.Dispose(disposing); // unsubscribes the dispatcher handlers }
