commit 5454da3bcaa383f5b47984283f11f010d3d2b73e Author: Greg Hudson Date: Wed May 1 13:07:36 2013 -0400 Don't use portmapper in RPC tests On many Linux systems, due to what is arguably a bug in rpcbind, the portmapper doesn't allow service registration from non-root processes. This causes the RPC tests to be frequently skipped. Modify the tests so that they don't need the portmapper, by grabbing the port number from the server process and passing it to the client. diff --git a/doc/build/doing_build.rst b/doc/build/doing_build.rst index bc438c8..3c686cc 100644 --- a/doc/build/doing_build.rst +++ b/doc/build/doing_build.rst @@ -149,9 +149,6 @@ However, there are several prerequisites that must be satisfied first: **-**\ **-disable-rpath**, which renders the build tree less suitable for installation, but allows testing without interference from previously installed libraries. -* In order to test the RPC layer, the local system has to be running - the portmap daemon and it has to be listening to the regular network - interface (not just localhost). There are additional regression tests available, which are not run by ``make check``.
