Subject [jira] [Comment Edited] (HTTPCLIENT-1478) https calls ignore http.socket.timeout during SSL Handshake

httpclient 4.3.6 with httpcore 4.3.3 -> problem exists.

I am using a lot of threads that do https requests through proxy.
And some of those threads ( 5-20 from 300 ) hang on:

http-outgoing-76778 >> "CONNECT host.ru:443 HTTP/1.1[\r][\n]"
http-outgoing-76778 >> "Host: host.ru[\r][\n]"
Http-outgoing-76778 >> "Proxy-Connection: Keep-Alive[\r][\n]"
http-outgoing-76778 >> "[\r][\n]"

Timeout is set with RequestConfig.setConnectTimeout and RequestConfig.setTimeout.

> https calls ignore http.socket.timeout during SSL Handshake. This can result in a https
call hanging forever waiting for socket read. 
> In both SSLSocketFactory and SSLConnectionSocketFactory, sslsock.startHandshake(); is
called before socket timeout is set on the socket. This means timeout is not respected during
the SSL handshake, and the thread can hang with a stacktrace that looks like this:
> org.apache.http.impl.client.AbstractHttpClient.doExecute
> org.apache.http.impl.client.DefaultRequestDirector.execute
> org.apache.http.impl.client.DefaultRequestDirector.tryConnect
> org.apache.http.impl.conn.ManagedClientConnectionImpl.open
> org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection
> org.apache.http.conn.ssl.SSLSocketFactory.connectSocket
> org.apache.http.conn.ssl.SSLSocketFactory.connectSocket
> sun.security.ssl.SSLSocketImpl.startHandshake
> sun.security.ssl.SSLSocketImpl.startHandshake
> sun.security.ssl.SSLSocketImpl.performInitialHandshake
> sun.security.ssl.SSLSocketImpl.readRecord
> sun.security.ssl.InputRecord.read
> sun.security.ssl.InputRecord.readV3Record
> sun.security.ssl.InputRecord.readFully
