Throughout mozmill and other Mozilla python code, checking the underlying platform is done in many different ways. The various checks needed lead to a lot of copy+pasting, leaving the reader to wonder….is this specific check necessary for (e.g.) an operating system? Because information is not consolidated, checks are not done consistently, nor is it defined what we are checking for.
proposes to solve this problem. mozinfo is a bridge interface,
making the underlying (complex) plethora of OS and architecture
combinations conform to a subset of values of relevance to
Mozilla software. The current implementation exposes relevant keys and
values such as:
processor. Additionally, the
service pack in use is available on the windows platform.
mozinfo is a python package. Downloading the software and running
python setup.py develop will allow you to do
is the only file contained is this package,
so if you need a single-file solution, you can just download or call
this file through the web.
The top level attributes (
available as module globals:
if mozinfo.os == 'win': ...
In addition, mozinfo exports a dictionary,
contain these values. mozinfo also exports:
choices: a dictionary of possible values for os, bits, and processor
main: the console_script entry point for mozinfo
unknown: a singleton denoting a value that cannot be determined
unknown has the string representation
unknown will evaluate as
False in python:
if not mozinfo.os: ... # unknown!
Command Line Usage¶
mozinfo comes with a command line program,
mozinfo which may be used to
diagnose one’s current system.
os: linux version: Ubuntu 10.10 bits: 32 processor: x86
Three of these fields, os, bits, and processor, have a finite set of
choices. You may display the value of these choices using
mozinfo --bits, and
mozinfo --help documents command-line usage.
Update the info.
Parameters: new_info – Either a dict containing the new info or a path/url to a json file containing the new info.
Find a mozinfo.json file, load it, and update the info with the contents.
Parameters: dirs – Directories in which to look for the file. They will be searched after first looking in the root of the objdir if the current script is being run from a Mozilla objdir.
Returns the full path to mozinfo.json if it was found, or None otherwise.
A string version that can be compared with comparison operators.
