svn commit: r1870454 - in /httpd/httpd/trunk: CHANGES modules/http2/h2_config.c modules/http2/h2_h2.c modules/http2/h2_stream.c modules/slotmem/mod_slotmem_shm.c

Author: icing
Date: Tue Nov 26 09:36:28 2019
New Revision: 1870454

URL: http://svn.apache.org/viewvc?rev=1870454&view=rev
Log:
  *) mod_http2: Fixed interaction with mod_reqtimeout. A loaded mod_http2 was disabling the
     ssl handshake timeouts. Also, fixed a mistake of the last version that made `H2Direct` 
     always `on`, irregardless of configuration. Found and reported by
     <Ar...@united-security-providers.ch> and
     <Ma...@united-security-providers.ch>. [Stefan Eissing] 

  *) mod_http2: Multiple field length violations in the same request no longer cause
     several log entries to be written. [@mkauf]
