update-python-modules

NAME

update-python-modules - byte-compile python modules

SYNOPSIS

update-python-modules [options] [directory [...]]

DESCRIPTION

The update-python-modules command is part of the python-support bundle.

update-python-modules is responsible for the byte-compilation of python modules. When used in byte-compilation mode, it will byte-compile modules in the directories given on the command line. When use in installation mode, it will byte-compile them once for each installed python version, and will make them available for all of them.

At each invocation, with or without arguments, update-python-modules will check for installed python versions, and will build or remove modules according to new or removed versions since the last time it was run.

OPTIONS

-h, --help

Show summary of options.

-v, --verbose

Detail all actions while they are performed.

-b, --bytecompile

Byte-compilation only mode. This is the default. In this mode, byte-compiled modules are put directly in the directories given on the command line. This mode is meant to be used for private python modules, which only need to be bytecompiled for the current python version.

-i, --install

Installation mode. In this mode, modules must be located in /usr/share/python-support/package/. They are byte-compiled for each python version, and put in separate directories. Files that don't end with .py are symlinked to their original place. The /usr/lib/python-support/package/pythonX.Y/ directories are also searched for files to be installed for a single python version. If a .version file is found in a directory, the module will be compiled only for the python versions listed in it.

-c, --clean

Clean modules instead of installing them. Beware, this option behaves differently in byte-compilation and installation modes.

-a, --rebuild-all

Rebuild all modules that were installed using -b. This is necessary when the default python version was changed, for example. .TP -f, --force-rebuild-all Clean all modules and rebuild them, whether they were compiled using -b or -i.

FILES

/var/lib/python-support/pythonX.Y/

These directories contain the byte-compiled modules for version pythonX.Y, for modules installed using -i.
