tinyproxy: explicitly flush logged messages On Windows, output streams are buffered when redirected to a file, and TerminateProcess() apparently doesn't trigger a flush. This left test-http-proxy.t missing part of the last line when it cat'd proxy.log[1]. Flushing stderr is all that is needed (on py27 anyway). I originally flushed stdout too, but that added additional output to the log: $ cat proxy.log + Accept: $LOCALIP (localhost)\r (esc) + Serving HTTP on 0.0.0.0 port 20810 ...\r (esc) + connect to localhost:$HGPORT\r (esc) * - - [*] "GET http://localhost:$HGPORT/?cmd=capabilities HTTP/1.1" - - (glob) + bye\r (esc) + connect to localhost:$HGPORT\r (esc) * - - [*] "GET http://localhost:$HGPORT/?cmd=branchmap HTTP/1.1" - - x-hgproto-1:0.1 0.2 comp=*zlib,none,bzip2 (glob) + bye\r (esc) + connect to localhost:$HGPORT\r (esc) * - - [*] "GET http://localhost:$HGPORT/?cmd=stream_out HTTP/1.1" - - x-hgproto-1:0.1 0.2 comp=*zlib,none,bzip2 (glob) + bye\r (esc) + connect to localhost:$HGPORT\r (esc) ...
