# 1.0.8 - changed Windows support to read version from kernel32.dll
|
2016-02-06 09:36:57 +00:00
|
|
|
# 1.0.7 - added DEV_NULL
|
|
|
|
|
# 1.0.6 - added linux_distribution()
|
|
|
|
|
# 1.0.5 - fixed Java support to allow running the module on Jython
|
|
|
|
|
# 1.0.4 - added IronPython support
|
|
|
|
|
# 1.0.3 - added normalization of Windows system name
|
|
|
|
|
# 1.0.2 - added more Windows support
|
|
|
|
|
# 1.0.1 - reformatted to make doc.py happy
|
|
|
|
|
# 1.0.0 - reformatted a bit and checked into Python CVS
|
|
|
|
|
# 0.8.0 - added sys.version parser and various new access
|
|
|
|
|
# APIs (python_version(), python_compiler(), etc.)
|
|
|
|
|
# 0.7.2 - fixed architecture() to use sizeof(pointer) where available
|
|
|
|
|
# 0.7.1 - added support for Caldera OpenLinux
|
|
|
|
|
# 0.7.0 - some fixes for WinCE; untabified the source file
|
|
|
|
|
# 0.6.2 - support for OpenVMS - requires version 1.5.2-V006 or higher and
|
|
|
|
|
# vms_lib.getsyi() configured
|
|
|
|
|
# 0.6.1 - added code to prevent 'uname -p' on platforms which are
|
|
|
|
|
# known not to support it
|
|
|
|
|
# 0.6.0 - fixed win32_ver() to hopefully work on Win95,98,NT and Win2k;
|
|
|
|
|
# did some cleanup of the interfaces - some APIs have changed
|
|
|
|
|
# 0.5.5 - fixed another type in the MacOS code... should have
|
|
|
|
|
# used more coffee today ;-)
|
|
|
|
|
# 0.5.4 - fixed a few typos in the MacOS code
|
|
|
|
|
# 0.5.3 - added experimental MacOS support; added better popen()
|
|
|
|
|
# workarounds in _syscmd_ver() -- still not 100% elegant
|
|
|
|
|
# though
|
|
|
|
|
# 0.5.2 - fixed uname() to return '' instead of 'unknown' in all
|
|
|
|
|
# return values (the system uname command tends to return
|
2018-12-31 23:25:26 +00:00
|
|
|
# 'unknown' instead of just leaving the field empty)
|
2016-02-06 09:36:57 +00:00
|
|
|
# 0.5.1 - included code for slackware dist; added exception handlers
|
|
|
|
|
# to cover up situations where platforms don't have os.popen
|
|
|
|
|
# (e.g. Mac) or fail on socket.gethostname(); fixed libc
|
|
|
|
|
# detection RE
|
|
|
|
|
# 0.5.0 - changed the API names referring to system commands to *syscmd*;
|
|
|
|
|
# added java_ver(); made syscmd_ver() a private
|
|
|
|
|
# API (was system_ver() in previous versions) -- use uname()
|
|
|
|
|
# instead; extended the win32_ver() to also return processor
|
|
|
|
|
# type information
|
|
|
|
|
# 0.4.0 - added win32_ver() and modified the platform() output for WinXX
|
|
|
|
|
# 0.3.4 - fixed a bug in _follow_symlinks()
|
|
|
|
|
# 0.3.3 - fixed popen() and "file" command invokation bugs
|
|
|
|
|
# 0.3.2 - added architecture() API and support for it in platform()
|
|
|
|
|
# 0.3.1 - fixed syscmd_ver() RE to support Windows NT
|
|
|
|
|
# 0.3.0 - added system alias support
|
|
|
|
|
# 0.2.3 - removed 'wince' again... oh well.
|
|
|
|
|
# 0.2.2 - added 'wince' to syscmd_ver() supported platforms
|
|
|
|
|
# 0.2.1 - added cache logic and changed the platform string format
|
|
|
|
|
# 0.2.0 - changed the API to use functions instead of module globals
|
|
|
|
|
# since some action take too long to be run on module import
|
|
|
|
|
# 0.1.0 - first release
