Oliver Tan 175856ffd3 add GSS authentication to pgproto3 2022-04-12 07:13:21 -05:00
Yuli Khodorkovskiy 7c9e840726 Add support for identifying authentication messages 
The pgprotocol overloads 'p' messages with PasswordMessage,
SASLInitialResponse, SASLResponse, and GSSResponse. This patch allows
contextual identification of the message by setting the authType in the
frontend and then setting this value in the backend when a
AuthenticationResponseMessage is received.

Jack Christensen fede0ce5d6 Document that received messages are only valid until the next receive. 2020-09-05 11:30:23 -05:00
Jack Christensen 595780be0f Map io.EOF errors to io.ErrUnexpectedEOF 
io.EOF is never expected during valid usage. In addition, database/sql
uses io.EOF as a sentinal value that all rows from a query have been
received.

Jack Christensen b3d0cbd0e6 Fix reading interrupted messages 
When an message is received and a timeout occurs after reading the
header but before reading the entire body the connection state could
be corrupted due to the header being consumed. The next read would
consider the body of the previous message as the header for the next.

fixes #348
