Checkin some changes related to experiment automation and vnode feedback: * configure, configure.in: Add sensors/canaryd/feedbacklogs template. * db/libdb.pm.in, db/xmlconvert.in: Add "virt_user_environment" table that holds environment variable names and values. * event/lib/event.c: Allocate memory of the right size for event_notifications. * event/program-agent/GNUmakefile.in: Add version.c file and add install targets for the man page. * event/program-agent/program-agent.8: Man page describing the program-agent daemon. * event/program-agent/program-agent.c: Add a bunch of convenience features: let the user specify the working directory for commands; save output to separate files on every invocation of an agent; let the user specify a timeout for a command; make the set of environment variables sane and add vars given in the NS file in the opt array; a "status" file containing process information is written out when children are collected. Internal changes: child processes are collected immediately, instead of waiting for the next START event, so we can send back COMPLETE events; the daemon now runs with a real-time priority, to increase the chances of receiving events. * event/proxy/evproxy.c: Made it bidirectional so the program-agent's COMPLETE events make it back to the scheduler. * event/sched/error-record.c: Change the default log directory. * event/sched/event-sched.h, event/sched/event-sched.c: Setup an environment similar to a program-agent to run the user's log digester. * event/sched/node-agent.cc: Add a handler for the SNAPSHOT event that runs create_image for the node. * event/sched/simulator-agent.h, event/sched/simulator-agent.cc: Let the user specify a "DIGESTER" script that digests the log files into a summary of the results. Add event handler for remapping a vnode experiment. * event/sched/timeline-agent.c: Accept the RUN event as well as the START event. * os/GNUmakefile.in: Install the install-tarfile.1 man page. * os/install-tarfile: Automatically chown/chgrp any files that do not have valid user or group IDs, the new owner will be the user that swapped in the experiment. Include the install directory in the DB file. Add a "list" mode that just dumps what files have been installed and where. Add a "force" option so the user can forcefully install the file, even though the DB says its already there. * os/install-tarfile.1: Man page describing the install-tarfile tool. * os/syncd/GNUmakefile.in: Install man pages on ops. * sensors/canaryd/GNUmakefile.in: Link canaryd statically and install "feedbacklogs" tool. * sensors/canaryd/canaryd.c: Dump dummynet pipe data. * sensors/canaryd/canarydEvents.c: Log errors. * sensors/canaryd/feedbacklogs.in: Tool used to generate feedback data from canaryd log files. * sensors/slothd/GNUmakefile.in: Install digest-slothd on ops. * sensors/slothd/digest-slothd: Fix some bugs and write out an "alert" file with all the nodes/links that were overloaded. * tbsetup/os_load.in, tbsetup/libosload.pm.in: Add "waitmode" argument that lets you specify that you want to wait for the disk to finish loading and/or wait for the node to come back up in the new OS. * tbsetup/power.in: Remove debugging printf. * tbsetup/ns2ir/node.tcl, tbsetup/ns2ir/program.tcl, tbsetup/ns2ir/sequence.tcl, tbsetup/ns2ir/sim.tcl.in: Fix some quoting problems with event-sequences. Add -expected-exit-code and -tag options to the "$program run" event. Add -digester to the "$ns report" event that lets the user specify a program to run to digest the log files. * tbsetup/ns2ir/tb_compat.tcl.in: Change the initial scaling factor for feedback nodes to 1%, instead of 100%. * tmcd/tmcd.c, tmcd/common/libtmcc.pm: Add "userenv" command that returns the values in "virt_user_environment". Return new program agent fields: dir, timeout, and expected_exit_code. * tmcd/common/GNUmakefile.in: Install rc.canaryd. * tmcd/common/bootvnodes: Add hack to boost the program-agents to a real-time priority, they can't do it from inside the jail. * tmcd/common/rc.canaryd: Rc script for canaryd. * tmcd/common/watchdog: Don't fail outright if there is a bad line in the battery.log * tmcd/common/rc.progagent: Append "userenv" data to the program-agent config file. * utils/GNUmakefile.in: Install loghole and its man page on ops. * utils/loghole.1: Document "clean" command and the change in loghole directories. * utils/loghole.in: Add "clean" command and parallelization. * xmlrpc/emulabserver.py.in: Add "virt_user_environment" table. Order the eventlist by "idx" and time, needed for sequences. And removed unnecessary nologin checks.
