patch 9.0.1776: No support for stable Python 3 ABI
Problem: No support for stable Python 3 ABI
Solution: Support Python 3 stable ABI
Commits:
1) Support Python 3 stable ABI to allow mixed version interoperatbility
Vim currently supports embedding Python for use with plugins, and the
"dynamic" linking option allows the user to specify a locally installed
version of Python by setting `pythonthreedll`. However, one caveat is
that the Python 3 libs are not binary compatible across minor versions,
and mixing versions can potentially be dangerous (e.g. let's say Vim was
linked against the Python 3.10 SDK, but the user sets `pythonthreedll`
to a 3.11 lib). Usually, nothing bad happens, but in theory this could
lead to crashes, memory corruption, and other unpredictable behaviors.
It's also difficult for the user to tell something is wrong because Vim
has no way of reporting what Python 3 version Vim was linked with.
For Vim installed via a package manager, this usually isn't an issue
because all the dependencies would already be figured out. For prebuilt
Vim binaries like MacVim (my motivation for working on this), AppImage,
and Win32 installer this could potentially be an issue as usually a
single binary is distributed. This is more tricky when a new Python
version is released, as there's a chicken-and-egg issue with deciding
what Python version to build against and hard to keep in sync when a new
Python version just drops and we have a mix of users of different Python
versions, and a user just blindly upgrading to a new Python could lead to
bad interactions with Vim.
Python 3 does have a solution for this problem: stable ABI / limited API
(see https://docs.python.org/3/c-api/stable.html). The C SDK limits the
API to a set of functions that are promised to be stable across
versions. This pull request adds an ifdef config that allows us to turn
it on when building Vim. Vim binaries built with this option should be
safe to freely link with any Python 3 libraies without having the
constraint of having to use the same minor version.
Note: Python 2 has no such concept and this doesn't change how Python 2
integration works (not that there is going to be a new version of Python
2 that would cause compatibility issues in the future anyway).
---
Technical details:
======
The stable ABI can be accessed when we compile with the Python 3 limited
API (by defining `Py_LIMITED_API`). The Python 3 code (in `if_python3.c`
and `if_py_both.h`) would now handle this and switch to limited API
mode. Without it set, Vim will still use the full API as before so this
is an opt-in change.
The main difference is that `PyType_Object` is now an opaque struct that
we can't directly create "static types" out of, and we have to create
type objects as "heap types" instead. This is because the struct is not
stable and changes from version to version (e.g. 3.8 added a
`tp_vectorcall` field to it). I had to change all the types to be
allocated on the heap instead with just a pointer to them.
Other functions are also simply missing in limited API, or they are
introduced too late (e.g. `PyUnicode_AsUTF8AndSize` in 3.10) to it that
we need some other ways to do the same thing, so I had to abstract a few
things into macros, and sometimes re-implement functions like
`PyObject_NEW`.
One caveat is that in limited API, `OutputType` (used for replacing
`sys.stdout`) no longer inherits from `PyStdPrinter_Type` which I don't
think has any real issue other than minor differences in how they
convert to a string and missing a couple functions like `mode()` and
`fileno()`.
Also fixed an existing bug where `tp_basicsize` was set incorrectly for
`BufferObject`, `TabListObject, `WinListObject`.
Technically, there could be a small performance drop, there is a little
more indirection with accessing type objects, and some APIs like
`PyUnicode_AsUTF8AndSize` are missing, but in practice I didn't see any
difference, and any well-written Python plugin should try to avoid
excessing callbacks to the `vim` module in Python anyway.
I only tested limited API mode down to Python 3.7, which seemes to
compile and work fine. I haven't tried earlier Python versions.
2) Fix PyIter_Check on older Python vers / type##Ptr unused warning
For PyIter_Check, older versions exposed them as either macros (used in
full API), or a function (for use in limited API). A previous change
exposed PyIter_Check to the dynamic build because Python just moved it
to function-only in 3.10 anyway. Because of that, just make sure we
always grab the function in dynamic builds in earlier versions since
that's what Python eventually did anyway.
3) Move Py_LIMITED_API define to configure script
Can now use --with-python-stable-abi flag to customize what stable ABI
version to target. Can also use an env var to do so as well.
4) Show +python/dyn-stable in :version, and allow has() feature query
Not sure if the "/dyn-stable" suffix would break things, or whether we
should do it another way. Or just don't show it in version and rely on
has() feature checking.
5) Documentation first draft. Still need to implement v:python3_version
6) Fix PyIter_Check build breaks when compiling against Python 3.8
7) Add CI coverage stable ABI on Linux/Windows / make configurable on Windows
This adds configurable options for Windows make files (both MinGW and
MSVC). CI will also now exercise both traditional full API and stable
ABI for Linux and Windows in the matrix for coverage.
Also added a "dynamic" option to Linux matrix as a drive-by change to
make other scripting languages like Ruby / Perl testable under both
static and dynamic builds.
8) Fix inaccuracy in Windows docs
Python's own docs are confusing but you don't actually want to use
`python3.dll` for the dynamic linkage.
9) Add generated autoconf file
10) Add v:python3_version support
This variable indicates the version of Python3 that Vim was built
against (PY_VERSION_HEX), and will be useful to check whether the Python
library you are loading in dynamically actually fits it. When built with
stable ABI, it will be the limited ABI version instead
(`Py_LIMITED_API`), which indicates the minimum version of Python 3 the
user should have, rather than the exact match. When stable ABI is used,
we won't be exposing PY_VERSION_HEX in this var because it just doesn't
seem necessary to do so (the whole point of stable ABI is the promise
that it will work across versions), and I don't want to confuse the user
with too many variables.
Also, cleaned up some documentation, and added help tags.
11) Fix Python 3.7 compat issues
Fix a couple issues when using limited API < 3.8
- Crash on exit: In Python 3.7, if a heap-allocated type is destroyed
before all instances are, it would cause a crash later. This happens
when we destroyed `OptionsType` before calling `Py_Finalize` when
using the limited API. To make it worse, later versions changed the
semantics and now each instance has a strong reference to its own type
and the recommendation has changed to have each instance de-ref its
own type and have its type in GC traversal. To avoid dealing with
these cross-version variations, we just don't free the heap type. They
are static types in non-limited-API anyway and are designed to last
through the entirety of the app, and we also don't restart the Python
runtime and therefore do not need it to have absolutely 0 leaks.
See:
- https://docs.python.org/3/whatsnew/3.8.html#changes-in-the-c-api
- https://docs.python.org/3/whatsnew/3.9.html#changes-in-the-c-api
- PyIter_Check: This function is not provided in limited APIs older than
3.8. Previously I was trying to mock it out using manual
PyType_GetSlot() but it was brittle and also does not actually work
properly for static types (it will generate a Python error). Just
return false. It does mean using limited API < 3.8 is not recommended
as you lose the functionality to handle iterators, but from playing
with plugins I couldn't find it to be an issue.
- Fix loading of PyIter_Check so it will be done when limited API < 3.8.
Otherwise loading a 3.7 Python lib will fail even if limited API was
specified to use it.
12) Make sure to only load `PyUnicode_AsUTF8AndSize` in needed in limited API
We don't use this function unless limited API >= 3.10, but we were
loading it regardless. Usually it's ok in Unix-like systems where Python
just has a single lib that we load from, but in Windows where there is a
separate python3.dll this would not work as the symbol would not have
been exposed in this more limited DLL file. This makes it much clearer
under what condition is this function needed.

Use at your own risk! Getscript is a plugin that simplifies retrieval of the latest versions of the scripts that you yourself use! Typing |:GLVS| will invoke getscript; it will then use the <GetLatestVimScripts.dat> (see |GetLatestVimScripts_dat|) file to get the latest versions of scripts listed therein from http://vim.sf.net/. ============================================================================== 1.

GetLatestVimScripts -- Getting Started *getscript-start* *getlatestvimscripts-install* VERSION FROM VIM DISTRIBUTION *glvs-dist-install* Vim 7.0 does not include the GetLatestVimScripts.dist file which serves as an example and a template. So, you'll need to create your own! See |GetLatestVimScripts_dat|. VERSION FROM VIM SF NET *glvs-install* NOTE: The last step, that of renaming/moving the GetLatestVimScripts.dist file, is for those who have just downloaded GetLatestVimScripts.tar.bz2 for the first time. The GetLatestVimScripts.dist file serves as an example and a template for your own personal list. Feel free to remove all the scripts mentioned within it; the "important" part of it is the first two lines. Your computer needs to have wget or curl for GetLatestVimScripts to do its work. 1. if compressed: gunzip getscript.vba.gz 2. Unix: vim getscript.vba :so % :q cd ~/.vim/GetLatest mv GetLatestVimScripts.dist GetLatestVimScripts.dat (edit GetLatestVimScripts.dat to install your own personal list of desired plugins -- see |GetLatestVimScripts_dat|) 3. Windows: vim getscript.vba :so % :q cd **path-to-vimfiles**/GetLatest mv GetLatestVimScripts.dist GetLatestVimScripts.dat (edit GetLatestVimScripts.dat to install your own personal list of desired plugins -- see |GetLatestVimScripts_dat|) ============================================================================== 3. GetLatestVimScripts Usage *glvs-usage* *:GLVS* Unless it has been defined elsewhere, > :GLVS will invoke GetLatestVimScripts(). If some other plugin has defined that command, then you may type > :GetLatestVimScripts < The script will attempt to update and, if permitted, will automatically install scripts from http://vim.sourceforge.net/. To do so it will peruse a file, > .vim/GetLatest/GetLatestVimScripts.dat (unix) < or > ..wherever..\vimfiles\GetLatest\GetLatestVimScripts.dat (windows) (see |glvs-data|), and examine plugins in your [.vim|vimfiles]/plugin directory (see |glvs-plugins|). Scripts which have been downloaded will appear in the ~/.vim/GetLatest (unix) or ..wherever..\vimfiles\GetLatest (windows) subdirectory. GetLatestVimScripts will attempt to automatically install them if you have the following line in your <.vimrc>: > let g:GetLatestVimScripts_allowautoinstall=1 The <GetLatestVimScripts.dat> file will be automatically be updated to reflect the latest version of script(s) so downloaded. (also see |glvs-options|) ============================================================================== 4. GetLatestVimScripts Data File *getscript-data* *glvs-data* *:GetLatestVimScripts_dat* The data file <GetLatestVimScripts.dat> must have for its first two lines the following text: > ScriptID SourceID Filename -------------------------- < Following those two lines are three columns; the first two are numeric followed by a text column. The GetLatest/GetLatestVimScripts.dist file contains an example of such a data file. Anything following a #... is ignored, so you may embed comments in the file. The first number on each line gives the script's ScriptID. When you're about to use a web browser to look at scripts on http://vim.sf.net/, just before you click on the script's link, you'll see a line resembling http://vim.sourceforge.net/scripts/script.php?script_id=40 The "40" happens to be a ScriptID that GetLatestVimScripts needs to download the associated page, and is assigned by vim.sf.net itself during initial uploading of the plugin. The second number on each line gives the script's SourceID. The SourceID records the count of uploaded scripts as determined by vim.sf.net; hence it serves to indicate "when" a script was uploaded. Setting the SourceID to 1 insures that GetLatestVimScripts will assume that the script it has is out-of-date. The SourceID is extracted by GetLatestVimScripts from the script's page on vim.sf.net; whenever it is greater than the one stored in the GetLatestVimScripts.dat file, the script will be downloaded (see |GetLatestVimScripts_dat|). If your script's author has included a special comment line in his/her plugin, the plugin itself will be used by GetLatestVimScripts to build your <GetLatestVimScripts.dat> file, including any dependencies on other scripts it may have. As an example, consider: > " GetLatestVimScripts: 884 1 :AutoInstall: AutoAlign.vim This comment line tells getscript.vim to check vimscript #884 and that the script is automatically installable. Getscript will also use this line to help build the GetLatestVimScripts.dat file, by including a line such as: > 884 1 :AutoInstall: AutoAlign.vim < assuming that such a line isn't already in GetLatestVimScripts.dat file. See |glvs-plugins| for more. Thus, GetLatestVimScripts thus provides a comprehensive ability to keep your plugins up-to-date! In summary: * Optionally tell getscript that it is allowed to build/append a GetLatestVimScripts.dat file based upon already installed plugins: > let g:GetLatestVimScripts_allowautoinstall=1 < * A line such as > " GetLatestVimScripts: 884 1 :AutoInstall: AutoAlign.vim < in an already-downloaded plugin constitutes the concurrence of the plugin author that getscript may do AutoInstall. Not all plugins may be AutoInstall-able, and the plugin's author is best situated to know whether or not his/her plugin will AutoInstall properly. * A line such as > 884 1 :AutoInstall: AutoAlign.vim < in your GetLatestVimScripts.dat file constitutes your permission to getscript to do AutoInstall. AutoInstall requires both your and the plugin author's permission. See |GetLatestVimScripts_dat|. *GetLatestVimScripts_dat* As an example of a <GetLatestVimScripts.dat> file: > ScriptID SourceID Filename -------------------------- 294 1 :AutoInstall: Align.vim 120 2 Decho.vim 40 3 DrawIt.tar.gz 451 4 EasyAccents.vim 195 5 engspchk.vim 642 6 GetLatestVimScripts.vim 489 7 Manpageview.vim < Note: the first two lines are required, but essentially act as comments. ============================================================================== 5. GetLatestVimScripts Friendly Plugins *getscript-plugins* *glvs-plugins* (this section is for plugin authors)~ If a plugin author includes the following comment anywhere in their plugin, GetLatestVimScripts will find it and use it to automatically build the user's GetLatestVimScripts.dat files: > src_id v " GetLatestVimScripts: ### ### yourscriptname ^ scriptid < As an author, you should include such a line in to refer to your own script plus any additional lines describing any plugin dependencies it may have. Same format, of course! If your command is auto-installable (see |glvs-autoinstall|), and most scripts are, then you may include :AutoInstall: just before "yourscriptname": > src_id v " GetLatestVimScripts: ### ### :AutoInstall: yourscriptname ^ scriptid < NOTE: The :AutoInstall: feature requires both the plugin author's and~ the user's permission to operate!~ GetLatestVimScripts commands for those scripts are then appended, if not already present, to the user's GetLatest/GetLatestVimScripts.dat file. It is a relatively painless way to automate the acquisition of any scripts your plugins depend upon. Now, as an author, you probably don't want GetLatestVimScripts to download your own scripts atop your own copy, thereby overwriting your not-yet-released hard work. GetLatestVimScripts provides a solution for this: put > 0 0 yourscriptname < into your <GetLatestVimScripts.dat> file and GetLatestVimScripts will skip examining the "yourscriptname" scripts for those GetLatestVimScripts comment lines. As a result, those lines won't be inadvertently installed into your <GetLatestVimScripts.dat> file and subsequently used to download your own scripts. This is especially important to do if you've included the :AutoInstall: option. Be certain to use the same "yourscriptname" in the "0 0 yourscriptname" line as you've used in your GetLatestVimScripts comment! ============================================================================== 6. GetLatestVimScripts AutoInstall *getscript-autoinstall* *glvs-autoinstall* GetLatestVimScripts now supports "AutoInstall". Not all scripts are supportive of auto-install, as they may have special things you need to do to install them (please refer to the script's "install" directions). On the other hand, most scripts will be auto-installable. To let GetLatestVimScripts do an autoinstall, the data file's comment field should begin with (surrounding blanks are ignored): > :AutoInstall: < Both colons are needed, and it should begin the comment (yourscriptname) field. One may prevent any autoinstalling by putting the following line in your <.vimrc>: > let g:GetLatestVimScripts_allowautoinstall= 0 < With :AutoInstall: enabled, as it is by default, files which end with ---.tar.bz2 : decompressed & untarred in .vim/ directory ---.vba.bz2 : decompressed in .vim/ directory, then vimball handles it ---.vim.bz2 : decompressed & moved into .vim/plugin directory ---.tar.gz : decompressed & untarred in .vim/ directory ---.vba.gz : decompressed in .vim/ directory, then vimball handles it ---.vim.gz : decompressed & moved into .vim/plugin directory ---.vba : unzipped in .vim/ directory ---.vim : moved to .vim/plugin directory ---.zip : unzipped in .vim/ directory and which merely need to have their components placed by the untar/gunzip or move-to-plugin-directory process should be auto-installable. Vimballs, of course, should always be auto-installable. When is a script not auto-installable? Let me give an example: .vim/after/syntax/blockhl.vim The <blockhl.vim> script provides block highlighting for C/C++ programs; it is available at: http://vim.sourceforge.net/scripts/script.php?script_id=104 Currently, vim's after/syntax only supports by-filetype scripts (in blockhl.vim's case, that's after/syntax/c.vim). Hence, auto-install would possibly overwrite the current user's after/syntax/c.vim file. In my own case, I use <aftersyntax.vim> (renamed to after/syntax/c.vim) to allow a after/syntax/c/ directory: http://vim.sourceforge.net/scripts/script.php?script_id=1023 The script allows multiple syntax files to exist separately in the after/syntax/c subdirectory. I can't bundle aftersyntax.vim in and build an appropriate tarball for auto-install because of the potential for the after/syntax/c.vim contained in it to overwrite a user's c.vim. ============================================================================== 7. GetLatestVimScripts Options *glvs-options* > g:GetLatestVimScripts_wget < default= "wget" This variable holds the name of the command for obtaining scripts. > g:GetLatestVimScripts_options < default= "-q -O" This variable holds the options to be used with the g:GetLatestVimScripts_wget command. > g:GetLatestVimScripts_allowautoinstall < default= 1 This variable indicates whether GetLatestVimScripts is allowed to attempt to automatically install scripts. Furthermore, the plugin author has to have explicitly indicated that his/her plugin is automatically installable (via the :AutoInstall: keyword in the GetLatestVimScripts comment line). > g:GetLatestVimScripts_autoinstalldir < default= $HOME/.vim (linux) default= $HOME/vimfiles (windows) Override where :AutoInstall: scripts will be installed. Doesn't override vimball installation. > g:GetLatestVimScripts_scriptaddr < default='http://vim.sourceforge.net/script.php?script_id=' Override this if your system needs ... ='http://vim.sourceforge.net/script/script.php?script_id=' ============================================================================== 8. GetLatestVimScripts Algorithm *glvs-algorithm* *glvs-alg* The Vim sourceforge page dynamically creates a page by keying off of the so-called script-id. Within the webpage of http://vim.sourceforge.net/scripts/script.php?script_id=40 is a line specifying the latest source-id (src_id). The source identifier numbers are always increasing, hence if the src_id is greater than the one recorded for the script in GetLatestVimScripts then it's time to download a newer copy of that script. GetLatestVimScripts will then download the script and update its internal database of script ids, source ids, and scriptnames. The AutoInstall process will: Move the file from GetLatest/ to the following directory Unix : $HOME/.vim Windows: $HOME\vimfiles if the downloaded file ends with ".bz2" bunzip2 it else if the downloaded file ends with ".gz" gunzip it if the resulting file ends with ".zip" unzip it else if the resulting file ends with ".tar" tar -oxvf it else if the resulting file ends with ".vim" move it to the plugin subdirectory ============================================================================== 9.
