MemoryError vs malloc error
Hi, I've a long running python process (running on freebsd). Sometimes when it uses too much memory it core dumps. I would've expected it to raise MemoryError. Normally, when would a python process raise MemoryError and when would it fail with malloc error and cores? This is happening in pure python code (Eg. if ' '.join(biglist)) etc. Regards, Amit -- http://mail.python.org/mailman/listinfo/python-list
Reference Cycles with instance method
Simple question. If I have the following code:
class A:
def __init__(self, s):
self.s = s
self.m2 = m1
def m1(self):
pass
if __name__ == '__main__':
a = A("ads")
a.m1()
a = None
The object is not garbage collected, since there appears to be a cycle
(between method m2 and A). I would expect this to behave the same as
having another method "def m2(self): self.m1()", but unfortunately its
not.
In above case m2 seems to be in a.__dict__ which is causing the cycle.
Any idea why this is so?
Regards,
Amit

Memory Usage of Strings
I'm observing a strange memory usage pattern with strings. Consider the following session. Idea is to create a list which holds some strings so that cumulative characters in the list is 100MB. >>> l = [] >>> for i in xrange(10): ... l.append(str(i) * (1000/len(str(i This uses around 100MB of memory as expected and 'del l' will clear that. >>> for i in xrange(2): ... l.append(str(i) * (5000/len(str(i This is using 165MB of memory. I really don't understand where the additional memory usage is coming from. If I reduce the string size, it remains high till it reaches around 1000. In that case it is back to 100MB usage. Python 2.6.4 on FreeBSD. Regards, Amit -- http://mail.python.org/mailman/listinfo/python-list
Re: Memory Usage of Strings
sum(map(len, l)) => 8200 for 1st case and 9100 for 2nd case. Roughly 100MB as I mentioned.

python and ARM memory types
I am running python in the ARM architecture (arm64 to be exact). The CPU Arch I use has clusters (2 big cores in a cluster and 2 small cores in another cluster think : A57, A53). It's going to be run in Ubuntu 14.04 I am trying to run traffic that stresses the interconnects of the clusters. One example is dekker's algorithm : pin first process to 1 cluster and another process to another cluster and check the algo (using multiprocessing library). Also I am also trying to run "streaming" traffic - the kind of traffic that you don't want in the cache because it is non-temporal. But how do I specify (streaming,write-combining,write-back) memory types in python ? Is there a library that I can use ? I am thinking of programming some fixed memory space (say 0x1000_000 - 0x2000_000) as "WC or WT or streaming" using the OS and then try to use the mmap facility in python. What set of libraries can I use ? Where should I start ? Fixed memories are discouraged so what kind of alternatives I can use ? Thanks, Vox -- https://mail.python.org/mailman/listinfo/python-list
Minimal Python Build in Docker Container
Hello, I wanted to share what I've learned about making a reasonably minimal Docker image containing CPython built from source. Motivation: Many popular distros are not able to provide packaged builds of the desired Python version. Operators of co-tenanted Python services have struggled since the dawn of time to manage the Matrix of Hell with Python apps - system Python version versus versions required by different applications versus shared lib versions, etc. We have made due with "almost good enough" tools like virtualenv, pyenv, and Software Collections. In spite of this, many operators just gave up and decided every Python service ought to live inside its own virtual machine. To me, it seems like we finally have a real solution: Compile Python from source with the version and deps you need inside a Standard Container on top of the distro of your choosing. Disclaimer: I have never been involved in the Python project or in the packaging of Python libs for any distro, so excuse me if this is naive. If you, like me, have decided the key to sanity is in containerized Python services, you might try pulling the official Docker Python image: python 2.7.7 a87a2288ce782 weeks ago 1.041 GB Hmm, Python 2.7.8 has been out for over a month with "regression and security fixes over 2.7.7". Also, over 1 GB? The "debian:wheezy" image with Python 2.7.3 installed from apt-get weighs in at 124 MB. And finally, this image is running on top of a pre-release version of the as-yet unreleased debian jessie. So we have 3 very good reasons from staying away from the official Python Docker image. Let's build our own. We chose Centos 7 as the standard base for both Docker hosts and guest containers. Here's what I did: FROM centos:centos7 RUN yum install -y tar gcc make RUN mkdir /usr/src/python WORKDIR /usr/src/python RUN curl -Sl "https://www.python.org/ftp/python/2.7.8/Python-2.7.8.tar.xz"; \ | tar -xJ --strip-components=1 # You may want to verify the download with gpg: https://www.python.org/download RUN ./configure \ && make -j$(nproc) \ && make install \ && make clean # Clean up prior to flattening RUN yum remove -y tar gcc make \ && yum clean all \ && rm -rf /usr/src/python Beginning with the 244 MB Centos 7 base image, this yields a 369 MB image after flattening, with a compiled Python 2.7.8. While +125 MB to the base is not terrible, it seems like the image could still lose some weight. Any ideas? If you would like to check out the built image, it is at marina/python:2.7.8_r1 on the public registry. Of course I recommend building your own with whatever makes sense for your "Python base" for production use! -- https://mail.python.org/mailman/listinfo/python-list
GeoBases V5 beta release
Hello! We just released the new beta version of GeoBases. For those who do not know GeoBases, this project provides tools to play with geographical data. It also works with non-geographical data, except for map visualizations :). There are embedded data sources in the project, but you can easily play with your own data in addition to the available ones. After data loading, you can: - perform various types of queries (find this key, or find keys with this property) - make fuzzy searches based on string distance (find things roughly named like this) - make phonetic searches (find things sounding like this) - make geographical searches (find things next to this place) - get results on a map, or on a graph, or export it as csv data, or as a Python object A few highlights of this new version: - sub-indexes - join clauses - better zsh autocomplete - sources admin mode - beginner's mode - phonetic search - graph display Get the code from Github https://github.com/opentraveldata/geobases Get the latest news from https://twitter.com/GeoBasesDev/ If you like it, share it! -- http://mail.python.org/mailman/listinfo/python-list

Michael, Ben & others: The short answer is others on a shared system, or malware that could modify the scripts. I'm new to python programming and there are just some paradigms I'm having trouble grasping. If the scripts can be modified (very easily), how can the application be trusted? i.e. If its an address book, then it would be trivial for malware to modify the script to override data or send it somewhere else... It would also seem like it makes user authentication through a password/ username, or encryption useless. The script could easily be modified to by-pass authentication and encryption could be disabled. Please correct any wrong assumptions that I might be making.. In a compiled application its not impossible to by pass the code.. but its not so easy. Perhaps this is just a side-effect of being a scripted language - not a flaw, just me trying to use it for something its not well suited for. - Kiel -- http://mail.python.org/mailman/listinfo/python-list
