This release has improvements in all areas. Many bug fixes are accompanied with optimization changes towards value tracing.
Fix, the new setuptools runners were not used by
pipbreaking the use of Nuitka from PyPI.
Fix, imports of
six.movescould crash the compiler for built-in names. Fixed in 0.5.29.2 already.
Windows: Make the
nuitka-runnot a symlink as these work really bad on that platform, instead make it a full copy just like we did for
nuitka3-runalready. Fixed in 0.5.29.2 already.
Python3.5: In module mode,
types.coroutinewas monkey patched into an endless recursion if including more than one module, e.g. for a package. Fixed in 0.5.29.3 already.
Python3.5: Dictionary unpackings with both star arguments and non star arguments could leak memory. Fixed in 0.5.29.3 already.
Fix, distutils usage was not working for Python2 anymore, due to using
superfor what are old style classes on that version.
Fix, some method calls to C function members could leak references.
Python3.5: The bases classes should be treated as an unpacking too.
Windows: Added back batch files to run Nuitka from the command line. Fixed in 0.5.29.5 already.
--include-packageto force inclusion of a whole package with the submodules in a compilation result.
--include-moduleto force inclusion of a single module in a compilation result.
`multiprocessingplug-in got adapted to Python 3.4 changes and will now also work in accelerated mode on Windows.
It is now possible to specify the Qt plugin directories with e.g.
--plugin-enable-=qt_plugins=imageformatsand have only those included. This should avoid dependency creep for shared libraries.
Plugins can now make the decision about recursing to a module or not.
Plugins now can get their own options passed.
The re-raising of exceptions has gotten its own special node type. This aims at more readability (XML output) and avoiding the overhead of checking potential attributes during optimization.
floatto using a slot mechanism that also analyses the type shape and detects and warns about errors at compile time.
Changed the variable tracing to value tracing. This meant to cleanup all the places that were using it to find the variable.
Enable must have / must not value value optimization for all kinds of variables including module and closure variables. This often avoids error exits and leads to smaller and faster generated code.
Added burn test with local install of pip distribution to virtualenv before making any PyPI upload. It seems pip got its specific error sources too.
<python> -m lib2to3instead, as it seems at least Debian Testing stopped to provide the binary by default. For Python 2.6 and 3.2 we continue to rely on it, as the don't support that mode of operation.
The PyLint checks have been made more robust and even more Python3 portable.
Added PyLint to Travis builds, so PRs are automatically checked too.
Added test for distutils usage with Nuitka that should prevent regressions for this new feature and to document how it can be used.
Make coverage taking work on Windows and provide the full information needed, the rendering stage is not there working yet though.
Expanded the trick assignment test cases to cover more slots to find bugs introduced with more aggressive optimization of closure variables.
New test to cover multiprocessing usage.
Generating more code tests out of doctests for increased coverage of Nuitka.
--python-versionin tests where they still remained.
Split the forms of
longinto two different nodes, they share nothing except the name. Create the constants for the zero arg variant more immediately.
Split the output comparison part into a dedicated testing module so it can be re-used, e.g. when doing distutils tests.
Removed dead code from variable closure taking.
Have a dedicated module for the metaclass of nodes in the tree, so it is easier to find, and doesn't clutter the node base classes module as much.
Have a dedicated node for reraise statements instead of checking for all the arguments to be non-present.
There is now a pull request template for Github when used.
--python-versionargument which should be replaced by using
-m nuitkawith the correct Python version. Outputs have been updated to recommend this one instead.
Make automatic import sorting and autoformat tools properly executable on Windows without them changing new lines.
The documentation was updated to prefer the call method with
-m nuitkaand manually providing the Python binary to use.
This release continued the distutils integration adding first tests, but more features and documentation will be needed.
Also, for the locals dictionary work, the variable tracing was made generic, but not yet put to use. If we use this to also trace dictionary keys, we can expect a lot of improvements for class code again.
The locals dictionary tracing will be the focus before resuming the work on C types, where the ultimate performance boost lies. However, currently, not the full compatibility has been achieved even with
