SNI support in python 2.7 for Locust load tests

[Reddy]

Hello,

At the beginning - welcome everyone, as this is my first post here. I'm not an 
active Python developer now, but I have general knowledge of the language. 

I'm trying to use locust (http://locust.io/) to run load test of one site we're 
developing. Everything was running nice and smooth until we switch the servers 
to use SNI. SNI is not officially supported in python 2.7.5 but Locust doesn't 
work on python3 as it uses gevent which AFAIK are supported for python2 only. I 
finally managed to run our scripts on local Ubuntu after upgrading python to 
2.7.8 from utopic repository but I can't replicate the same on target CentOS 
where the scripts are supposed to be executed. I tried compiling python from 
http://www.python.org/ftp/python/2.7.8/Python-2.7.8.tar.xz, I even tried 
unpacking sources of Ubuntu python2.7 package (from 
http://se.archive.ubuntu.com/ubuntu/pool/main/p/python2.7/python2.7_2.7.8.orig.tar.gz),
 patching them with TLS1_1 and TLS1_2 support from  
https://bugs.python.org/file30761/python-2.7.5-tls1.1-and-tls1.2.patch) and 
still no luck. I do monkey patch in Locust startup file according to 
http://stackoverflow.com/a/19477363 (oth
 erwise it wouldn't work on Ubuntu as well) but still I get error stack as 
attached below. I also checked with pip list that all python packages have the 
same versions on both systems. Any idea what I'm missing on the target load 
test system which I have in Ubuntu? 

Regards,
Reddy

Thanks Christian and Dieter for your prompt responses!
I tried yesterday with Python built from 
https://hg.python.org/cpython/archive/9b4673d7b046.tar.gz. I also do use 
pyOpenSSL as described at http://stackoverflow.com/a/19477363 so I used pip to 
install pyOpenSSL, ndg-httpsclient and pyasn1 as well as patched locust startup 
file with the following:

from urllib3.contrib import pyopenssl
pyopenssl.inject_into_urllib3()

I also tried adding the following:
from functools import partial
ssl.wrap_socket = partial(ssl.wrap_socket, ssl_version=ssl.PROTOCOL_TLSv1)

Finally, I've just tried with:
/usr/local/bin/pip2.7 install backports.ssl

and patching the lucust file with:

import backports.ssl as ssl
import backports.ssl.monkey as monkey
import requests
monkey.patch()

I've also added verify=False to my locust test scripts to disable certificate 
verification according to http://docs.locust.io/en/latest/api.html

...And I still get exactly the same error:

[2014-09-30 14:19:41,793] ip-x-x-x-x/ERROR/stderr: File 
"build/bdist.linux-x86_64/egg/OpenSSL/SSL.py", line 977, in sendall

[2014-09-30 14:19:41,794] ip-x-x-x-x/ERROR/stderr: WantWriteError

Now I'm starting to think it's something else than SNI, but all those scripts 
were working nice before and the only change done was turning on the SNI on 
tested servers... 

Any idea what my actually cause this WantWriteError?

I think I have a clue what's wrong. By default using:
/usr/local/bin/pip2.7 install pyOpenSSL ndg-httpsclient pyasn1
gives me pyOpenSSL version 0.14. When I downgrade it to 0.13 with
/usr/local/bin/pip2.7 install pyOpenSSL==0.13
everything works nice and smooth. Interestingly, on my local Ubuntu I do have 
0.14 version of that package and it works well there...
I noticed that dowgrading it to 0.13 buids 'OpenSSL.crypto' extension and that 
does not happen when installing v. 0.14 so I guess there's simply a connection 
to openssl missing somehow there in 0.14. According to 
https://github.com/pyca/pyopenssl/releases there was a big change there:
"Second, pyOpenSSL is no longer implemented in C as a collection of extension 
modules using the Python/C API. Instead, pyOpenSSL is now a pure-Python project 
with a dependency on a new project, http://github.com/pyca/cryptography, which 
provides (among other things) a cffi-based interface to OpenSSL."
but I also have the most recent version of cryptography (0.6) installed there. 
And again - it works on local Ubuntu. Weird.

I guess I'll just stick to pyOpenSSL==0.13 for the time being, unless somebody 
gives me a hint what I'm doing wrong with 0.14 :)

Br,
Reddy

Try to use iterator function finditer instead of findall. To see the
difference run below code by calling findIter or findAll function one at a
time in for loop.  You can have achieve atleast 4x better performance.

I was written a simple tcp server in python, which is nicely communicating with

Hi,
Thanks for your reply, But how can i find client socketfd when i want send 
message to specific client.I can store connected client ip, port in database. 
how can use that ip, port when i want send.

Dear ChrisA,
Currently we are a team of three. We are planning to have contect 
categorized into topics like
☺ Some application made of python(command line program or a GUI program) that 
we make using a python module(planning to cover as many modules as possible) 
ie; of included batteries of python.
☺ Python in Security ie; Some scripts that we can write in python like a 
dictionary attack tool
☺ One for covering Tkinter.
☺ One small Game using python.
☺ Python Facts,Python Quotes, Python PersonalitY (a python personnel bio or an 
interview), Python video(about a python video from Python Conferences)
☺ Python articles Guest as well as our own.
☺ Python Tutorials.
☺ Python Place( A place where python is being used for production).
☺ If we are not overloading magazine we would also cover about Python tools 
like say Ninja-IDE(an IDE for Python extensively written in Python).
After a few days we are planning to cover
☺ Python in cloud.(Open Stack)
☺ Network Programming.(probably Twisted framework)
☺ Database programming with SQLite.
☺ Python Puzzles(some programming Questions).
☺ Python Webframework probably Django.
We welcome further suggestions from the community.

Thank you very much with your suggestion. I installed the python intepreter from SUSE CD but downloaded the sources of python from the python website. It seems like it created the mismatches here.

For certain compilers (msvc, cygwin, mingw) it'sappropriate to use the __declspec extension to make the Python sharedlibrary work properly. For other compilers, PyAPI_FUNC doesn't doanything special. It's through the presence of absence of defines likePy_ENABLE_SHARED and HAVE_DECLSPEC_DLL that Python decides how to definePyAPI_FUNC, and this little detail is usually below the radar.Jeff

I am trying to install Python 3.6.4 in my laptop. I am getting the following 
error. I also attached failure log as well in the mail. I could not change the 
path. It is automatically installing in C drive. Might be, this is restricted 
drive, so we got errors. I am not sure, but let me know as well to do the path 
changes at D drive.

Please suggest me to do the installation steps without failures of the attached 
logs.

Python Enhancement Proposal for List methods

[Siva Sukumar Reddy]

Hey everyone,

I am really new to Python contribution community want to propose below
methods for List object. Forgive me if this is not the format to send an
email.

1. *list.replace( item_to_be_replaced, new_item )*: which replaces all the
occurrences of an element in the list instead of writing a new list
comprehension in place.
2. *list.replace( item_to_be_replaced, new_item, number_of_occurrences )*:
which replaces the occurrences of an element in the list till specific
number of occurrences of that element. The number_of_occurrences can
defaulted to 0 which will replace all the occurrences in place.
3. *list.removeall( item_to_be_removed )*: which removes all the
occurrences of an element in a list in place.

What do you think about these features?
Are they PEP-able? Did anyone tried to implement these features before?
Please let me know.

Thank you,
Sukumar

In programming language theory, there is no law to the effect that
"everything" should be of one kind or another.  So, we would not go with
Alan Kay's ideal.

Having said that, theorists do want to unify concepts wherever possible and
wherever they make sense.  Imperative programming types, which I will call
"storage types", are semantically the same as classes.  Bare storage types
have predefined operations for 'getting' and 'setting' whereas classes allow
user-defined operations.  So, the distinction made between them in typical
programming languages is artificial and implementation-focused.  C and C++
are especially prone to this problem because they were designed for writing
compilers and operating systems where proximity to the machine architecture
seems quite necessary.  The higher-level languages such as Java are moving
towards abolishing the distinction.  Scala might be the best model in this
respect, though I do not know its type system fully.

Here are a couple of references in theoretical work that might be helpful in
understanding these connections:

- John Reynolds, The Essence of Algol, in de Bakker and van Vliet (eds)
Algorithmic Languages, 1981.  Also published in O'Hearn and Tennent (eds)
Algol-like Languages, Vol. A, 1997.

- Uday Reddy, Objects and Classes in Algol-like Languages, Information and
Computation, 172:63-97, 2002. (previously in FOOL workshop 1998.)
http://www.cs.bham.ac.uk/~udr/papers/classes.pdf

However, there are properties that are special to storage types, which are
not shared by all class types.  Sometimes, they simplify some theoretical
aspects.  It is not uncommon for authors to make a distinction between
storage types and general types.  An example is one of our own papers:

- Swarup, Reddy and Ireland: Assignments for applicative languages, FPCA
1991. http://www.cs.bham.ac.uk/~udr/papers/assign.pdf

Indeed.  However, this is not the only notion of type in imperative
programming languages.  For example, a function type in C or its descendants
is not there to describe storage, but to describe the interface of an
abstraction.  I will use Reynolds's term "phrase types" to refer to such
types.  Reynolds's main point in "The Essence of Algol" was to say that
phrase types are much more general, and a language can be built around them
in a streamlined way.  Perhaps "Streamlining Algol" would have been a more
descriptive title for his paper.  Nobody should be designing an imperative
programming language without having read "The Essence of Algol", but they
do.

Whether storage types (and their generalization, class types) should be
there in a type system at all is an open question.  I can think of arguments
both ways.  In Java, classes are types.  So are interfaces (i.e., phrase
types).  I think Java does a pretty good job of combining the two
in a harmonious way.

If you have trouble getting hold of "The Essence of Algol", please write to
me privately and I can send you a scanned copy.  The Handout 5B in my
"Principles of Programming Languages" lecture notes is a quick summary of
the Reynolds's type system.

The chasms are too many, not only between theoretical and applied
communities, but within each of them.  My feeling is that this is
inevitable.  Our field progresses too fast for people to sit back, take
stock of what we have and reconcile the multiple points of view.

There is nothing wrong with "Turing machines".  But the question in
programming language design is how to integrate the Turing machine concepts
with all the other abstractions we need (functions/procedures, modules,
abstract data types etc.), i.e., how to fit the Turing machine concepts into
the "big picture".  That is not an easy question to resolve, and there isn't
a single way of doing it.  So you see multiple approaches being used in the
practical programming languages, some cleaner than the others.

The abstract notions of academia do make it into the real world, but rather
more slowly than one would hope.  Taking Java for example, the initial
versions of Java treated interfaces in a half-hearted way, ignored
generics/polymorphism, and ignored higher-order functions.  But all of them
are slowly making their way into Java, with pressure not only from the
academic community but also through competition from other "practical"
languages like Python, C# and Scala.  If this kind of progress continues,
that is the best we can hope for in a fast-paced field like ours.

Uday Reddy

These distinctions are not fully valid.  

- Functional programming, logic programming and imperative programming are
three different *computational mechanisms*.

- Object-orientation and abstract data types are two different ways of
building higher-level *abstractions*.

The authors of this paragraph did not understand that computational
mechanisms and higher-level abstractions are separate, orthogonal dimensions
in programming language design.  All six combinations, obtained by picking a
computational mechanism from the first bullet and an abstraction mechanism
from the second bullet, are possible.  It is a mistake to put
object-orientation in the first bullet.  Their idea of "paradigm" is vague
and ill-defined.

I think there is some misunderstanding here.  Being "mathematical" in
academic work is a way of making our ideas rigorous and precise, instead of
trying to peddle wooly nonsense.  Providing a mathematical description does
not imply in any way that these ideas are not implementable on machines.  In
fact, very often these mathematical descriptions state precisely how to
implement the concepts (called operational semantics), but using
mathematical notation instead of program code.  The mathematical notation
used here is usually no more than high school set theory, used in a
stylized way.

In contrast, there are deeper "mathematical models" (called denotational
semantics and axiomatic semantics) which are invented to describe how
programming language features work in a deep, intrinsic way.  This is
similar to, for instance, how Physics invents mathematical models to capture
how the nature around us works.  Physicists don't need to "implement"
nature.  It has already been "implemented" for us before we are born.
However, to understand how it works, and how to design systems using
physical materials in a predictable way, we need the mathematical models
that Physics has develeped.

Similarly, the mathematical models of programming languages help us to
obtain a deep understanding of how languages work and how to build systems
in a predictable, reliable way.  It seems too much to expect, at the present
stage of our field, that all programmers should understand the mathematical
models.  But I would definitely expect that programming language designers
who are trying to build new languages should understand the mathematical
models.  Otherwise, they would be like automotive engineers trying to build
cars without knowing any Mechanics.

How about this one liner, if you prefer them;
set([(k,yourList.count(k)) for k in yourList])

Re: death of newsgroups (Microsoft closing their newsgroups)

the posters are always just the 20 or 30 known faces. I think perhaps
maybe no more than 100 different posters a year. Since this year or

comp.emacs is pretty much just me.

gnu.emacs.help is not much better. It's pretty much the same
developers and the same few elisp coders, with perhaps 1 new face with
once-per-lifetime post every few days. gnu.emacs.help is doing a bit
better because it is connected to fsf's mailing list.


Doing "better" means having more posts?  I don't believe that having a lot of 
posts is necessarily a measure of goodness.


In my opinion, discussion forums do well when they encourage people to think 
carefully and communicate clearly.  In this respect, I think mailing lists do 
worse, newsgroups better, and web-based forums the best.


Mailing lists seem to turn into talking shops where people get to know each 
other over time and their "public" nature gets lost.  Those who write a lot end 
up dominating them, independent of whether they write any sense or not.  The 
other people get tired and stop reading.  So, you can generate a lot of 
traffic, but its value is dubious.


Newsgroups are much better because they are public and, visibly so.  If 
somebody says something stupid, a lot of people will jump on them.  And, so, 
over time, they develop some quality.  (There is no guarantee, of course.  I 
have also seen a lot of newsgroups, especially in politics, really degenerate 
with opposing factions fighting and dominating everything else.)


Web-based forums, especially those where people have to register, work the best 
in my experience.  They are very visibly public, discouraging people to write 
nonsense.  The difficulty of writing on the web instead of your favorite editor 
hopefully provides some resistance to write.  So, people tend to think more 
than they write.


I used a forum called silentpcforum last year to help me build myself a new 
computer.  There was a lot of high quality information dating back to years, 
which was easy to find and easy to use.


So, if newsgroups die and get replaced by web forums, that would be a move for 
the better.  If they get replaced by mailing lists, that would be a move for 
the worse.
