> PythonImport that works for any interpreter. > -------------------------------------------- > > Key: MODPYTHON-117 > URL: http://issues.apache.org/jira/browse/MODPYTHON-117 > Project: mod_python > Type: Wish > Components: core > Versions: 3.2.7 > Reporter: Graham Dumpleton > Assignee: Graham Dumpleton > > Currently PythonImport requires that the name of the interpreter be > explicitly named. If running lots of virtual hosts, where each is dynamically > assigned their own interpreter name automatically, it is a lot of work to > have to specify PythonImport directives for all virtual host interpreters > where a particular module needs to be loaded in all interpreters. > Syntactically, it isn't hard to allow something like: > PythonImport moduleforallinterpreters > or: > PythonImport moduleforallinterpreters * > however the current location where such Python imports are done in mod_python > will not allow this. > This is because such Python imports are done in the PythonChildInitHandler() > function right after the child process is initialised. The code iterates > through the list of imports and creates interpreters for the named > interpreters and loads the modules. Where we want a module loaded into all > modules, we will not actually know the names of all potential modules in > advance at that point so can't do it. > The logical spot is to to load a module common to all modules in > get_interpreter() when a request is first made for the interpreter. Thus, it > may be possible to move the module imports from PythonChildInitHandler() into > get_interpreter(). > One issue that needs to be considered is that currently, having a > PythonImport directive means that any named interpreter is always created at > child initialisation, even if a request never arrives that is processed > within the context of that interpreter. It might also be worthwhile adding > syntax which allows one to specify whether a PythonImport should be performed > at the point of child initialisation, or only when a request comes in that > requires that specific interpreter. To keep backward compatability, the > default would be at child initialisation time. > Not sure what would be a good syntax. The options would be 'child > intialisation' and 'interpreter initialisation'.
