ZC Buildout recipe for precompiling .py files
Project description
ZC Buildout recipe for precompiling Python in product directories
This recipe searches for Python scripts with .py filename extensions and compiles them into .pyc bytecode files.
It will compile all the files in specified directories and their descendents. A “skip” list of directory names will be bypassed.
This recipe will probably usually be used in a Zope or Plone buildout using plone.recipe.* recipes. When it is, it will automatically use the product directories specified in plone.recipe.zope2instance recipes. Skip directories will be those required to produce an error-free build in that environment.
Precompiling Python code files to bytecode can prevent the Zope process from writing out .pyc files as it operates – which requires that the daemon process be able to write into program directories.
This recipe may return harmless warnings regarding the inability to compile skin layer scripts, which typically have “return” outside of a function. While these warnings are harmless, you may suppress them by tuning the skip list.
Usage
When used in a typical Plone install, usage is as simple as:
[precompile] recipe = plone.recipe.precompiler
When used in a different type of install, or with a need for manual tuning:
[precompile] recipe = plone.recipe.precompiler dirs = list of dirs in multiple indented lines skip = list of skip directories in multiple indented lines rx = individual file exclusion regular expression
Default usage is equivalent to:
[instance] ... [precompile] recipe = plone.recipe.precompiler dirs = ${instance:products} skip = tests skins doc kupu_plone_layer Extensions .svn rx = /\.
