Peter Otten,
Yes that seems to work better. Thanks for the tips. But I see now that
I am getting some http errors when I try to run this code from the Microsoft
Azure Notebooks. Here is the URL to my Note Book:
https://notebooks.azure.com/n/n31C2DSCOr8/notebooks/URLopen%20Test.ipynb
And here is the error:
URLError:
Does anybody know if something can be done about this with urllib? Or is
this completely related to the firewall rules at http://geonb.snb.ca??
Thanks,
Bernie.

Thomas,
The PID parameter at the end of my url must be enclosed in single quotes,
'75385120', or the API won't execute the query. I have the code in a python
notebook on Azure -

===
lst2 = lst1[1] removes first line of instructions
printing lst2[1:2] produces essentially the list of students and scores ??
([{u'student ': u'Hannah', u'score': 77}, {u'student ': u'Emily', u'score':
57}, {u'student ': u'Olivia', u'score': 80}, {u'student ': u'Nora', u'score':

I'm not surprised it is also failing. test_pickle appears to have a similar issue.

The abort is very rare for me on Linux, so much so that I originally thought it only occurred on Windows. I can't reproduce it on a local Linux machine, but it has happened inconsistently in our Jenkins cluster.

Then I tried with a MongoDB > server running. The problem only occurs for me when testing with a MongoDB instance running. Running background threads seem to be a key requirement for reproduction. Note also that this problem does not reproduce when using PyMongo's C extensions, only when using the pure python BSON encoder. You can run the tests like this from a clean git checkout: python3.5 setup.py --no_ext test > I don't have exactly the same version (I'm reading pymongo 3.0.3 source) Clone master from github: https://github.com/mongodb/mongo-python-driver > @Bernie: Would you be able to get a C backtrace using gdb on such crash?

[issue25222] 3.5.0 regression - Fatal Python error: Cannot recover from stack overflow
New submission from Bernie Hackett:
While running PyMongo's test suite against python 3.5.0 the interpreter
inconsistently aborts when we test encoding a recursive data structure like:
evil = {}
evil['evil'] = evil
The test that triggers this was added to test the use of Py_EnterRecursiveCall
in PyMongo's C extensions and passes without issues on all previous CPython
releases back to 2.4.x (the oldest version PyMongo supports). The interesting
thing about this abort is that it only occurs when testing PyMongo *without*
its C extensions. The stacktrace looks like this:
test_bad_encode (test_bson.TestBSON) ... Exception ignored in: >
RecursionError: maximum recursion depth exceeded while calling a Python object
Fatal Python error: Cannot recover from stack overflow.

[issue6901] Runaway programs often become unresponsive to CTRL-C
New submission from Bernie H. Innocenti ber...@codewiz.org:
On startup, the Python interpreter changes the default behavior
of SIGINT, which results in many Python programs to ignore the
keyboard interrupt exactly in the situations when users are
most likely to use it (i.e.: when the program becomes unresponsive).
Minimal testcase:
$ echo void foo() { for(;;) {} } foo.c
$ gcc -shared -o foo.so foo.c
$ python -c 'import ctypes;ctypes.CDLL(./foo.so).foo()'
^C^C^C
^C
^C DAMN!
^C
This scenario mimics a Python program calling some blocking library
function. It can also happen with IO-bound functions if they loop
on read() and don't abort on short reads.
One might be tempted to say this behavior of the Python intepreter
is by design and suggest users to use CTRL-\ instead of CTRL-C.
However, this non-standard behavior is very annoying for users who
expect ^C to work on UNIX systems. In fact, no other compiled or
interpreted language I know of behaves this way, and Python should
not be the only exception.
While I see the usefulness of KeyboardInterrupt from the programmer
point of view, only a minority of programs actually need to trap
SIGINT and do something with it. Other language runtimes require
the programmer to manually trap SIGINT when needed. The Python
interpreter could maintain backwards compatibility by enabling
automatic SIGINT trapping when entering a try block that would
intercept KeyboardInterrupt.

[issue6901] Runaway programs often become unresponsive to CTRL-C
Bernie H. Innocenti ber...@codewiz.org added the comment: This is a fundemental behavior that will never change. If you dislike it, you can remove the signal handler for it with the signal module. What? We could break the syntax of print statements and cannot change this minor detail that afftects many 1% of all Python programs? As a matter of fact, for 2 years I've been using this in my /usr/lib64/python2.6/sitecustomize.py: cut- import signal signal.signal(signal.SIGINT, signal.SIG_DFL) cut- ^C has been working perfectly ever since. So far, I have not yet found a single Python program where restoring the default behavior of SIGINT causes real issues, but there may certainly be a few. Granted, this is just a kludge, not a perfect fix, but from a user perspective, it already improves upon the current behavior (i.e. more pros than cons). At least, this is my personal experience. If you're skeptical, please try this workaround yourself for a few months and let me know what breaks for you. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6901 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
