Subject: [OMPI devel] OMPI 1.5 twitter notification plugin probably broken by switch to OAUTH
From: Chris Samuel (samuel_at_[hidden])

Hi folks,

Looking at the code for the Twitter notifier in OMPI 1.5
and seeing its use of HTTP basic authentication I would
suggest that it may be non-functional due to Twitters
switch to purely OAUTH based authentication for their API.

I'm trying to test it out here but I'm at a bit of a loss
to find a trivial command line to trigger a notifier, even
the syslog one! I've Googled and grep'd with no joy..

For instance:

chris_at_quad:/tmp/ompi$ ./bin/mpirun --mca notifier syslog --mca notifier_threshold_severity 99 --mca
notifier_base_verbose 99 /bin/doesnotexist
[quad:18429] mca: base: components_open: Looking for notifier components
[quad:18429] mca: base: components_open: opening notifier components
[quad:18429] mca: base: components_open: found loaded component syslog
[quad:18429] mca: base: components_open: component syslog has no register function
[quad:18429] mca: base: components_open: component syslog open function successful
[quad:18429] mca:base:select: Auto-selecting notifier components
[quad:18429] mca:base:select:(notifier) Querying component [syslog]
[quad:18429] mca:base:select:(notifier) Query of component [syslog] set priority to 1
[quad:18429] mca:base:select:(notifier) Selected component [syslog]
mpirun was unable to launch the specified application as it could not access
or execute an executable:

Executable: /bin/doesnotexist
Node: quad

while attempting to start process rank 0.
[quad:18429] mca: base: close: component syslog closed
[quad:18429] mca: base: close: unloading component syslog

But nothing appears in the syslog.

Ideas ?
