Hi all,
RE presents with SRC680 m212 the build tool's new feature. Now it is
possible to make distributed builds, ie - build one CWS/workspace using
multiple machines.
The usage is simple: you start client(s) on machines, that should be
used for builds, and "build --server" on the "master" machine. Client
machines should be usable as build machines, and they should have the
same paths to the sources as the master has.
=======================================================================
Usage:
master:
build --master --setenvstring "setenv_string" [--port PORT]
setenv_string - the command for setting the build environment
(imho
should be the same as used for master environment).
Does not need to be specified in SO(setsolar) environment
PORT - port number for server (default is one of range
7890-7894, assigned automatically)
client:
build_client [-PN] host[:port1:...:portN]|@server_list_file
-PN - number of client process to start. Each client process
operates as a independent client.
host[:port1:...:portN] - host/ports from which the jobs can
be accepted. There can be multiple hosts/ports at the same time.
Default - the client tries to connect the ports 7890-7894 of
each master
@server_list_file - path to the text file with server list,
specified as host1[:port1:...:portN] [host2[:port1:...:portN]
the file can be changed in the runtime - the changes will be
noticed
by the client
=======================================================================
This description is not complete, it covers basic usage. More detailed
description deliver the tools themselves...
The build tool in the master mode writes a html page, where one can see
the progress of the build process. The page is here(per default):
$SOLARSRC/$INPATH.build.html
All other features of the build tool are not changed.
I made a test on linux, and here are the results:
complete OOo local build on one machine: 4h 59m
complete OOo build on two machines, one machine - locally, another -
over nfs: 3h 07m
These results can be different on different OS, CPU, infrastructure.
I hope this feature will be useful.
Have fun,
Vladimir
