[Python-Dev] C ABI and #ifndef Py_LIMITED_API
In the CPython source code I see #ifndef Py_LIMITED_API Is there a section in the docs that explains the purpose? If not, can someone give me the cliff notes version?

IIUC, it would require stable component IDs for components to be upgraded, which I could not manage to provide. So, do you have any plans on dealing with a or b? So the stable component IDs is dealt with - WiX will auto-generate them based on the relative install path of each file and a user-provided ID (to distinguish between the 32-bit and 64-bit installs, for example. This ID is currently generated from the hash of a user provided URI, which is also used to generate upgrade codes and a few fixed component IDs). Installing patches is something we can defer until 3.5.1, but I am interested in looking into it. My main concern is that it may hurt fresh installs (for example, 3.5.5 is actually 3.5.0.msi+.1.msp+.2.msp+.3.msp+.4.msp+.5.msp) and I'm not sure that true slipstreams are supported/recommended because it will affect future patches (different product codes, IIRC). So fresh installs of later versions may have a significantly increased download size. Because of the split into multiple MSIs, it's also possible to independently version some parts of it. I suspect this will only apply to the py.exe launcher, but if that is unchanged between 3.5.0 and 3.5.1 then we can leave its version at 3.5.0 and it won't be redownloaded/installed. Not a huge saving, but it's a possibility. I expect most MSIs will change in some way between versions, so an MSP is the only good way to improve upgrades (the main benefit of the MSI split here is we will always install the latest 32-bit launcher, and if you install 3.5 32-bit and 64-bit and eventually 3.6 32-bit and 64-bit you'll only have one launcher installed). Another possible problem is that MSI uses file version information to determine whether to update files. .py files don't have version information, so MSI to MSI updates are probably always going to replace everything - another reason why MSPs are the only good choice here. I'll chat to some of the guys who work on the Visual Studio installer, since it uses the same technology and is far more complex than Python's one. They may have some suggestions about how to approach this. Other issues: - what MSI version do you require, and what is the minimum Windows version supporting that MSI version? I need to double-check the support still, but the aim is to support back to Windows Vista, so I think that's Windows Installer 3.0. Of more concern is the installer EXE, which is going to require a minimum level C runtime that may not be available before we've installed... - Since you are going to install into Program Files by default, I think the library should be precompiled by default - there is little chance that a regular user can save .pyc files when running Python. It might be possible to even include the pyc files in the distribution, if we can arrange to somehow support relative paths in co_filename. Agreed. The library will be precompiled by default if you choose the All Users button on the front page, and you can control this independently through the customize option (to precompile Just for Me or install without precompiling).

That said, there aren't that many changes to what is already in the guide - mostly new information that I'd like to add. I'll try and get something written up this week. Python 3.5 now requires Visual Studio 2010 *SP1*, or newer Visual Studio: http://bugs.python.org/issue22919#msg233637 Technically, Python 3.5 requires Visual Studio 2015, as the decision was made to move to the newer compiler for this release (and make whatever schedule changes were necessary to ensure everything will be available - it was on python-dev, though I don't have links handy). It will still open and build with Visual Studio 2010 SP1 or later, however, buildbots should move to VS 2015 as they can, since that will be the official toolset. (I'm not pushing too hard until 2015 RC is released, since that's when Microsoft start supporting upgrades to newer versions. We do have one buildbot that's already using VS 2015 Preview though.) I found PCbuild\readme.txt which is not mentionned in the devguide :-/ https://hg.python.org/cpython/file/56f717235c45/PCbuild/readme.txt (at least not on the Windows section of the setup page) That should help, since I've updated that file. Though it's a little ahead of its time still, so a lot of the instructions do not yet have to be followed strictly, and I consider being able to build with VS 2010 SP1 a feature that we want to keep supporting for now while we transition. I found some clues to build OpenSSL to be able to build the Python ssl module, but I still have issues. Is there a more complete documentation? I found how to install svn.exe, perl.exe and nasm.exe, but not how to install nmake.exe. I don't know the command to build OpenSSL. You don't require perl, you don't have to install nasm or build OpenSSL. Calling PCBuild/get_externals.bat will get nasm and the OpenSSL sources, and PCBuild/build.bat will rebuild OpenSSL as necessary. nmake is part of Visual C++, so it should be available once you have your path configured (PCBuild/env.bat). So a complete guide to check out and build Python on Windows should be: 1. Install SVN and put it on your path 2. Run PCBuild\get_externals.bat (this is the only step that requires SVN) 3. Install Visual Studio 2010 SP1 or later 4. Open PCBuild\pcbuild.sln in Visual Studio *or* run PCBuild\build.bat from the command line. I don't care of building OpenSSL, my goal is only to build the Python ssl module. Is there a way to install a development version of OpenSSL (.lib files if I remember correctly) from an installer/binary? If you can find ssleay.lib and libeay.lib somewhere, they'll probably work. If not, those projects are in PCBuild and will be built automatically (if necessary) when you build _ssl.vcxproj or _hashlib.vcxproj.

Note that this isn't precisely true; any VS 2010 SP1 or newer *should* work, as you already know :). This just says 2015 because that's the 'official' version to use. -- Zach ___ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

Lemburg m...@egenix.com: Just a note of caution: for older preview releases of VS the only way to get back to a clean system was to reinstall Windows. Does it mean that it's not possible to have VS 2008 and VS 2015 installed at the same time? It's possible, and that configuration will be fine. Until VS 2015 RC is released, there's no guarantee that it will uninstall or upgrade cleanly. The testing so far looks like it'll be fine, but there's no guarantee. There's also a chance that it will interfere with VS 2013, but any earlier versions will be fine. Cheers, Steve VS 2008 is required to build Python 2.7.
