| 42 | # 0.8.0 - added sys.version parser and various new access |
| 43 | # APIs (python_version(), python_compiler(), etc.) |
| 44 | # 0.7.2 - fixed architecture() to use sizeof(pointer) where available |
| 45 | # 0.7.1 - added support for Caldera OpenLinux |
| 46 | # 0.7.0 - some fixes for WinCE; untabified the source file |
| 47 | # 0.6.2 - support for OpenVMS - requires version 1.5.2-V006 or higher and |
| 48 | # vms_lib.getsyi() configured |
| 49 | # 0.6.1 - added code to prevent 'uname -p' on platforms which are |
| 50 | # known not to support it |
| 51 | # 0.6.0 - fixed win32_ver() to hopefully work on Win95,98,NT and Win2k; |
| 52 | # did some cleanup of the interfaces - some APIs have changed |
| 53 | # 0.5.5 - fixed another type in the MacOS code... should have |
| 54 | # used more coffee today ;-) |
| 55 | # 0.5.4 - fixed a few typos in the MacOS code |
| 56 | # 0.5.3 - added experimental MacOS support; added better popen() |
| 57 | # workarounds in _syscmd_ver() -- still not 100% elegant |
| 58 | # though |
| 59 | # 0.5.2 - fixed uname() to return '' instead of 'unknown' in all |
| 60 | # return values (the system uname command tends to return |
| 61 | # 'unknown' instead of just leaving the field emtpy) |
| 62 | # 0.5.1 - included code for slackware dist; added exception handlers |
| 63 | # to cover up situations where platforms don't have os.popen |
| 64 | # (e.g. Mac) or fail on socket.gethostname(); fixed libc |
| 65 | # detection RE |
| 66 | # 0.5.0 - changed the API names referring to system commands to *syscmd*; |
| 67 | # added java_ver(); made syscmd_ver() a private |
| 68 | # API (was system_ver() in previous versions) -- use uname() |
| 69 | # instead; extended the win32_ver() to also return processor |
| 70 | # type information |
| 71 | # 0.4.0 - added win32_ver() and modified the platform() output for WinXX |
| 72 | # 0.3.4 - fixed a bug in _follow_symlinks() |
| 73 | # 0.3.3 - fixed popen() and "file" command invokation bugs |
| 74 | # 0.3.2 - added architecture() API and support for it in platform() |
| 75 | # 0.3.1 - fixed syscmd_ver() RE to support Windows NT |
| 76 | # 0.3.0 - added system alias support |
| 77 | # 0.2.3 - removed 'wince' again... oh well. |
| 78 | # 0.2.2 - added 'wince' to syscmd_ver() supported platforms |
| 79 | # 0.2.1 - added cache logic and changed the platform string format |
| 80 | # 0.2.0 - changed the API to use functions instead of module globals |
| 81 | # since some action take too long to be run on module import |
| 82 | # 0.1.0 - first release |
