1 2 3 4 5 6 7 | 2000-06-01 Scott Stanton <stanton@ajubasolutions.com> * tlsIO.c: Restored call to Tcl_NotifyChannel from ChannelHandler to ensure that events propagate from the lower driver. This may result in an infinite loop in some cases, so this is not a total fix. This may be sufficient for now, however. [Bug: 5623] | > > > > > > | 1 2 3 4 5 6 7 8 9 10 11 12 13 | 2000-06-05 Brent Welch <welch@ajubasolutions.com> * tls.c, tlsIO.c: Split Tls_Free into Tls_Clean, which does the SSL cleanup, and the Tcl_Free call. It is important to shutdown the SSL state "synchronously" during a stacked flush. 2000-06-01 Scott Stanton <stanton@ajubasolutions.com> * tlsIO.c: Restored call to Tcl_NotifyChannel from ChannelHandler to ensure that events propagate from the lower driver.
