cpython/PC/dllbase_nt.txt

In Win32, DLL's are "pre-linked" using a specified base address.
When the DLL is loaded, an attempt is made to place it at
that address.  If that address is already in use, a new base address
is selected, and the DLL subject to fixups.  Apparently, these
fixups are very slow, and significant performance gains can be
made by selecting a good base address.

This document is to allocate base addresses to core Python
and Python .PYD files, to give a better change of optimal performance.
This base address is passed to the linker using the /BASE
command line switch.

datetime escapes the sandbox. The Windows build is all set. I leave it to others to argue about how to build it on other platforms (on Windows it's in its own DLL). 2002-12-16 16:18:38 -04:00			`This document is to allocate base addresses to core Python`

Start building the bz2 module on Windows. CAUTION: The Python test still has many failures, but I'm out of time for this now (already took much longer than hoped to get this far). The base bz2 library does pass its own tests (see next). CAUTION: People building on Windows have to download and build tne bz2 compression libraries now.
