CakePHP 1.3 - Ciclo infinito nelle librerie di dolci, arresto di Apache, aiuto di sessione e __start()?

Question

Dopo aver aggiunto l'helper di sessione al controller dell'app, Apache inizia a bloccarsi. Ho rintracciato il problema con la registrazione e trovato che in/CORE/cake/libs/controller/component/session la funzione check() inizia a funzionare una volta e non viene completata. Tuttavia, la funzione che chiama, __start(), viene eseguita all'infinito (almeno finché Apache non si blocca). E correndo all'infinito intendo che l'intera funzione __start() viene eseguita più volte fino in fondo. Ancora una volta, ciò accade quando aggiungo l'helper di sessione nel controller dell'app. Senza di esso, Cake sembra funzionare bene fino a quando non raggiungo un punto in cui l'helper di sessione viene utilizzato in una vista. Questo sistema è stato aggiornato da Cake 1.1 e in Cake 1.1 l'helper di sessione è stato incluso automaticamente e ha funzionato correttamente. Ho provato su Cake 1.3.7 e Cake 1.3.15 con lo stesso risultato. Sto indovinando qualcosa con le impostazioni della sessione in conflitto con il modo in cui Cake 1.3 fa le cose. Di seguito è riportato il mio file config/core, le informazioni sugli arresti anomali di Apache e il registro di Apache subito prima del crash. Se qualche altra informazione sarebbe utile per favore fammelo sapere nei commenti. Qualche suggerimento su come risolvere questo problema? Grazie!

MODIFICA: Ho dimenticato di includere uno discussion here rilevante. Sfortunatamente, non hanno una soluzione chiara qui, ma sembrano voler correggere l'errore nella torta, dove sarei felice di alterare il mio codice per evitare il bug.

MODIFICA 2: Recentemente ho scoperto che il gestore di questo progetto prevede di interrompere l'utilizzo delle sessioni del database in futuro, in modo tale da risolvere completamente la situazione per me. Ovviamente lascerò questa domanda per i futuri visitatori.

Answer 1

ho trovato una soluzione che permette di versione del database delle sessioni per funzionare. Non è una correzione, ma probabilmente funzionerà per la mia situazione, anche se la soluzione reale sarebbe comunque preferibile.

Il lavoro attorno è quello di trasformare l'agente spuntare:

Configure::write('Session.checkAgent', false);
