Subject svn commit: r1051084 - in /couchdb/branches/1.0.x/src/ibrowse: Makefile.am ibrowse.app.in ibrowse.erl ibrowse_http_client.erl ibrowse_test.erl
Date Mon, 20 Dec 2010 12:34:53 GMT
Author: fdmanana

New Revision: 1051084

URL: http://svn.apache.org/viewvc?rev=1051084&view=rev
Log:
Merged revision 1051082 from trunk

Upgraded ibrowse to version 2.1.2 (released today)

This version fixes a blocking issue (which rarely happens) when using the same connection
(with ot without pipelining) for multiple requests using the option {stream_to, {pid(), once}}.
