eGenix PyRun 2.1.2 GA

eGenix PyRun - One file Python Runtime 2.1.2 GA

eGenix is pleased to announce our new open-source eGenix PyRun - One file Python runtime 2.1.2 for Python 2.6, 2.7 and Python 3.4.


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.

This patch level release of eGenix PyRun 2.1 comes with the following enhancements:

Enhancements / Changes

  • Upgraded eGenix PyRun to work with and use Python 2.7.11 per default. Python 2.7.11 now uses computed gotos in the interpreter loop, adding some more performance. In addition, the vulnerable SSLv3 protocol was switched off in the defaults of the ssl module.
  • Upgraded eGenix PyRun to work with and use Python 3.4.4 for the Python 3 version.
  • Added an explicit --libpath configure setting to work a problem with some 64-bit platforms defaulting to lib64/. The new setting forces the libs to always go into a lib/ directory.

install-pyrun Enhancements

  • Updated install-pyrun to default to eGenix PyRun 2.1.2 and its feature set.

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