Brython 3.2.8 released

[Pierre Quentel]

Hi,

I have released version 3.2.8 of Brython and updated brython.info.

The latest release was more than 3 months old, an eternity... It's hard to select features among all the changes in this version, but I mention :

• the port of Unicode-related methods of str() (by Quentin Santos)
• the addition of a code profiler (by Jonathan Verner)
• a rewriting of the generators implementation : it doesn't use attributes defined at compilation time anymore. This is part of the work required to achieve the goals suggested by Glyph in issue #491 : "Feature Request: Brython Production App Development Pipeline"

In the next weeks development will focus on this issue. I will also try to fix the memory leaks that I observe when I run the test suite several times.

Many thanks to all contributors !
- Pierre

Complete changelog :


New features
============
- port of Unicode-related methods of str() (by Quentin Santos)

- add and document a code profiler (by Jonathan Verner)
- allow sending files in XMLHttpRequests (idem)
- implement a Console (and XMLHTTP) handler for the logging module (idem)

- rewrite the generators implementation : it doesn't use attributes defined
  at compilation time anymore. This is part of the work required to achieve
  the goals suggested by Glyph in issue #491 : "Feature Request: Brython
  Production App Development Pipeline"

- support "return expression" in generators. Add attribute "value" to
  StopIteration
- deployment should always be over https. Change the URL used for deployment
  to an HTTPS URL (by Glyph)
 
Implementation
==============
- reduce number of calls to getattr() in function calls and in setattr(), to
  improve performance
- add many "var" in scripts to reduce global Javascript namespace pollution
- change the attribute __mro__ of class objects : it doesn't start with the
  class object itself, to avoid circular references

Bug fixes
=========
- bug in SyntaxError reporting
- remove method __or__ of object
- bug with function calls (would evaluate the function object 2 times)

  undefined` on editor
- #465 : context-defined variable not declared
- #466: add method `json.load()` (by Quentin Santos)
- #467: incorrect SyntaxError with imports (idem)
- #469: add `co_flags` property to Code objects (idem)
- #470 : incorrect evaluation of generators

- #480 : functions cannot have 'throw' keyword arguments
- #481 : super() behaviour does not match Python's when an object's
  '__class__' attribute is changed

- #486 : fix formating precision for floats close to 0 (by Jonathan Verner)
- #498 : multiplying complex numbers by floats does not work
- #506 : error in round() (by Jonathan)

They are almost the same, I found a small bug just after releasing the version and uploaded a new one a few minutes later. I thought I had removed the version at 15:54:06... It's done now. Thanks for reporting this !
