ANNOUNCING

                 eGenix PyRun - One file Python Runtime

                            Version 2.1.0


         An easy-to-use single file relocatable Python run-time -
           available for Linux, Mac OS X and Unix platforms,
                 with support for Python 2.6, 2.7 and
                       **also for Python 3.4**.


This announcement is also available on our web-site for online reading:

INTRODUCTION

eGenix PyRun is our open source, one file, no installation version of
Python, making the distribution of a Python interpreter to run based
scripts and applications to Unix based systems as simple as copying a
single file.

eGenix PyRun's executable only needs 11MB for Python 2 and 13MB for
Python 3, but still supports most Python application and scripts - and
it can be compressed to just 3-4MB using upx, if needed.

Compared to a regular Python installation of typically 100MB on disk,
eGenix PyRun is ideal for applications and scripts that need to be
distributed to several target machines, client installations or
customers.

It makes "installing" Python on a Unix based system as simple as
copying a single file.

eGenix has been using eGenix PyRun internally in the mxODBC Connect
Server product since 2008 with great success and decided to make it
available as a stand-alone open-source product.

We provide both the source archive to build your own eGenix PyRun, as
well as pre-compiled binaries for Linux, FreeBSD and Mac OS X, as 32-
and 64-bit versions. The binaries can be downloaded manually, or you
can let our automatic install script install-pyrun take care of the
installation: ./install-pyrun dir and you're done.

Please see the product page for more details:

NEWS

This major new release of eGenix PyRun 2.1 comes with the following new features and changes:

New Features
------------

 * Upgraded eGenix PyRun to work with and use Python 2.7.9 per
   default.

 * Upgraded eGenix PyRun to work with and use Python 3.4.3 for Python
   3 support.

 * Added support for setting rpath on the PyRun binary to make it easy
   to ship external libraries together with PyRun, without having to
   set the LD_LIBRARY_PATH variable.

 * Added special support for egenix-pyopenssl to load its OpenSSL libs
   during startup.

 * PyRun allows to disable the new default HTTPS certificate
   verification (PEP 476) by setting the env var PYRUN_HTTPSVERIFY to
   0. Default is to apply certificate verification.

 * Add support for more Python command line options: -s and -3 are
   ignored, -R raises an error explaining to use the PYTHONHASHSEED
   env var instead, -B prevents writing of byte code files.This should
   increase compatibility of PyRun with the standard Python command
   line interface.

Enhancements / Changes
----------------------

 * Added patch for Python 2.7.9 and 3.4.3 to make ctypes work again
   after changes to those versions of Python. See
   https://bugs.python.org/issue23042 for details.

 * The PyRun -v command line switch will now be passed to Python and
   supports setting the level using e.g. -vv for a verbose 2 level.

 * Disabled user site configurations in PyRun, since these are not
   needed or wanted for typical PyRun uses and cost startup time.

 * Optimized sys.path setup a bit. PyRun won't check for a Python
   build run and will not check lib/site-python on startup anymore.

 * PyRun for Python 3.4 is no longer compiled to always run in
   optimized mode. This allows using asserts in tests again.

Fixes
-----

 * Entering "license" in the interactive shell now returns the correct
   URL for all supported Python versions.

 * Tilde expansion now works for most arguments of install-pyrun. This
   wasn't working before due to a bug.

install-pyrun Quick Install Enhancements
---------------------------------------------

eGenix PyRun includes a shell script called install-pyrun, which
greatly simplifies installation of PyRun. It works much like the
virtualenv shell script used for creating new virtual environments
(except that there's nothing virtual about PyRun environments).

    https://downloads.egenix.com/python/install-pyrun

With the script, an eGenix PyRun installation is as simple as running:

    ./install-pyrun targetdir

This will automatically detect the platform, download and install the
right pyrun version into targetdir.

We have updated this script since the last release:

 * Updated install-pyrun to default to eGenix PyRun 2.1.0 and its
   feature set.

 * Added -r/--requirements option which allows automatically
   installing a set of required packages using a requirements file, so
   you can easily set up a complete Python environment using a single

   ./install-pyrun -r requirements.txt targetdir

 * Updated install-pyrun to install pyrun 2.1.0, setuptools 15.2 and
   pip 1.5.6 per default.

For a complete list of changes, please see the eGenix PyRun Changelog:

Really interesting. 

Should we consider this to be an improvement towards the slow startup problem ? 

It seems to have really decreased the number of failed attempt to open files (ENOENT's appearing with strace upon startup) due to the interpreter default behavior for module loading on startup. (with a simple hello world I got 72 ENOENT's against 307 from default python installation on my standard ubuntu machine).

This problem mainly shows up when slow access storages are used (say raspberry + sdcard). Any chances you can provide this tool as prebuilt arm binaries ?

My assumptions may be all wrong, but anyway thanks for sharing your work. :)

We have been providing binaries for Raspberry Pis for quite
some time, but without official support, so they are not listed
on the product page.

If you run install-pyrun on a Raspi, this should install PyRun
for you. I'm not sure whether it'll work on the new Raspi 2.
We'll probably add one to our build farm in a few weeks.

[Multipart message — attachments visible in raw view] — view raw

Well I gave it a try, and it seems my assumptions were *somehow* true.
Here is what I got when running one of my apps in single shot mode (load,
run, terminate):

*default python distribution*
total time 9.022s
ENOENT's count 7377

*pyrun*
total time 8.455s
ENOENT's count 3064

So, it indeed failed much less to open files, but I guess this didn't make
that much difference after all (500ms).
Perhaps it is because this app has some external dependencies (22 to be
precise) not bundled on pyrun that had to be scanned by the interpreter
anyway. If by any means we could bundle them all the same way, than it
could bring a much higher performance gain. But I guess it is not really
safe-feasible.

Thanks

PyRun has the advantage of being able to read the byte code
directly from the binary (using memory mapping). However,
it still needs to run the same startup machinery as Python
itself.

Note that startup time for Python was a lot worse before
Python used the same approach as PyRun to compile in the
parsed sysconfig data.

It's certainly possible to use the pyrun build system to create
bundles with more packages and tools included.

The one we're shipping has most of the stdlib included,
but leaves all the application code to reside on the
sys.path or in a ZIP archive.

In one of the next releases we'll probably add a tool to bundle
complete applications together with pyrun, perhaps even by
recompiling it to include the application byte code files
right in the binary like we do for the stdlib.

Well, that would be simply awesome. Looking forward to it.

PS: you guys should definitely advertise this work on the embedded software
community.

I think Activestate makes a Python 2.y for Solaris.

I've never used it.

We don't currently have direct access to these types of systems, so
cannot provide regular builds for these platforms.

For AIX and Solaris x86 we do provide custom paid support to get
our software ported, if you're interested in this.
