could you please send me the [REDACTED] bit from this ToolLog message?

The error indicates that the actual contents of that is incorrectly formatted.

Subject: [HTCondor-users] "Failed to receive remote ad" runtime error when querying history with the python api

Â

Hello HTCondor users,

Â

I get aÂ"Failed to receive remote ad" error when using the Python bindings to query history immediately after submitting a job. Looking into the HTCondor logs, I see the following error in ToolLog:

Â

[Timestamp] condor_history: getInheritedSocks from CONDOR_INHERIT is ... [REDACTED]

[Timestamp] ERROR "Assertion ERROR on (*ptmp == '*')" at line 2244 in file /slots/10/dir_3701941/userdir/.tmplMkQ9O/BUILD/condor-8.7.6/src/condor_io/sock.cpp

Â

I also see a core dump in the log directory.

Â

This error does not occur if I wait a few seconds before invoking schedd.history. Also, there is no error if I run the history query without submitting a job.

Â

Below is the Python code that triggers the problem.

Â

import htcondor

submit = htcondor.Submit({'executable': '/usr/bin/sleep', 'arguments': '300'})

schedd = htcondor.Schedd()

with schedd.transaction() as txn:

 print submit.queue(txn)

print list(schedd.history('true', ['ClusterId'], 10))

# RuntimeError: Failed to receive remote ad.

Â

Is there something I am missing? Thanks in advance for your help!
