This is to inform you about the new stable release of Nuitka. Please see the page "What is Nuitka?" for clarification of what it is now and what it wants to be.
This release 0.2.4 is likely the last 0.2.x release, as it's the one that
achieved feature parity with CPython 2.6, which was the whole point of the
release series, so time to celebrate. I have stayed away (mostly) from any
optimization, so as to not be premature.
From now on speed optimization is going to be the focus though. Because right
now, frankly, there is not much of a point to use Nuitka yet, with only a minor
run time speed gain in trade for a long compile time. But hopefully we can
change that quickly now.
New Features
The use of exec in a local function now adds local variables to scope it is
in.
The same applies to from module_name import * which is now compiled
correctly and adds variables to the local variables.
Bug Fixes
Raises UnboundLocalError when deleting a local variable with del
twice.
Raises NameError when deleting a global variable with del twice.
Read of to uninitialized closure variables gave NameError, but
UnboundLocalError is correct and raised now.
Cleanups
There is now a dedicated pass over the node tree right before code generation
starts, so that some analysis can be done as late as that. Currently this is
used for determining which functions should have a dictionary of locals.
Checking the exported symbols list, fixed all the cases where a static was
missing. This reduces the "module.so" sizes.
With gcc the "visibility=hidden" is used to avoid exporting the helper
classes. Also reduces the "module.so" sizes, because classes cannot be made
static otherwise.
New Tests
Added "DoubleDeletions" to cover behaviour of del. It seems that this is
not part of the CPython test suite.
The "OverflowFunctions" (those with dynamic local variables) now has an
interesting test, exec on a local scope, effectively adding a local variable
while a closure variable is still accessible, and a module variable too. This
is also not in the CPython test suite.
Restored the parts of the CPython test suite that did local star imports or
exec to provide new variables. Previously these have been removed.
Also "test_with.py" which covers PEP 343 has been reactivated, the with
statement works as expected.
