If provided, the the 'read_guard' method will be called when objects

lib/python/Products/PythonScripts/zbytecodehacks/ChangeLog deleted 100755 → 0
View file @ d7508240
1999-12-11 Evan Simpson <evan@4-am.com>
* Tupleizing and UntupleFunction now handle nested function definitions
* Subdirectories reverted to v0.5 bytecodehacks, since the only change
I've ever made was to accidentally change line endings in them to CRLF
1999-09-09 Evan Simpson <evan@4-am.com>
* Tupleizing a function now omits globals
* New UntupleFunction re-applies globals, with automatic initialization
of variables to None, since there's no way to check if they exist.
It also includes $functions, and checks __builtins__ handling.
* Moved all bytecode manipulation into Munge_window class, which uses
op.execute to maintain information about who did what to the stack.
* Added Munger which re-enables creation of dictionary literals.
* Made all Mungers load frequently used functions from the global dict
into the local instead of storing them in co_consts.
* Simplified GuardedOps and turned off test Guard.
* Wrote lots of docstring.
1999-08-28 Evan Simpson <evan@4-am.com>
* Ripped out Fleshy acquisition-style class and added
CycleHandle in an attempt to improve speed.
* code_editor.py: Added "as_tuple" to Function and EditableCode
to provide (hopefully) pickleable representations. Their __init__s
now accept these tuples.
* Added VSExec.py (the point of all this), which provides facilities
for compiling arbitrary blocks of code with heavy restrictions.
1999-06-11 Michael Hudson <mwh21@cam.ac.uk>
* a monumental amount has changed. I haven't been keeping the
ChangeLog up to date, sorry.
1999-05-16 Michael Hudson <mwh21@cam.ac.uk>
* doc/bch.tex: documented macro and macros.
* macros.py: added basic library of macros.
* setq2.py: does same job as setq.py, but uses the new macro
package.
* macro.py It's a macro packages of sorts. Needs documentation.
1999-05-15 Michael Hudson <mwh21@cam.ac.uk>
* inline.py: Substantially rewritten to use find_function_call,
and to support keyword arguments. No varags yet.
* setq.py Added changes written by Christian Tismer (now converts
globals to locals)
1999-05-13 Michael Hudson <mwh21@cam.ac.uk>
* Release 0.11 - cleaned up production of documentation following
advice from the documentation master, Fred L. Drake.
1999-05-12 Michael Hudson <mwh21@cam.ac.uk>
* Release 0.10.
* doc/ There's documentation (gasp)
1999-05-10 Michael Hudson <mwh21@cam.ac.uk>
* inline.py: Python now has inline functions! Bet you never
expected that.
* It's all changing again! Much polish, some docstrings,
everything rewritten to use code_editor that wasn't already, many
style fixes.
1999-05-06 Michael Hudson <mwh21@cam.ac.uk>
* attr_freeze.py: implement an attribute freezer that works.
* xapply2.py: implement xapply for functions (again!) using the
new code editing framework from code_editor.py.
* code_editor.py: That's more like it!
1999-05-04 Michael Hudson <mwh21@cam.ac.uk>
* attr_freeze.py: implements a (buggy) attempt at freezing
attribute references.
* read_code.py,opbases.py,ops.py,write_ops.py,
common.py,__init__.py: Much stuff added/changed. It not pretty or
internally consistent yet. I might bash on it some more some
time. I'm afraid I don't feel like explaining myself properly yet
either.
1999-05-02 Michael Hudson <mwh21@cam.ac.uk>
* README,ChangeLog: Added.
* xapply.py: Added, following prompting by Christian Tismer.
* closure.py: Made improvements suggested by Tim Peters.

View file @ d7508240
Welcome to the bytecodehacks!
There's docmentation in doc/; To build it you need an unpacked python
source distribution somewhere, and for html output you also need
latex2html.
Build docs like this:
$(path to Python source)/Doc/tools/mkhowto --$(format) (--a4) bch.tex
You can get built html docs at
ftp://starship.python.net/pub/crew/mwh/bytecodehacks-doc-$(VERSION).tar.gz.
The bytecodehacks rewrite the bytecode of functions to do unlikely
things in Python.
The package (and that's how it's distributed) splits into two parts -
the byte code editing routines and the "bytecodehacks" that are
usuable without a degree in python arcanery, although one might help
understand some of the consequences.
Some highlights:
bytecodehacks.closure - bind global references to constants
bytecodehacks.xapply - a sort-of lazy apply
bytecodehacks.setq - this one should interest people!
bytecodehacks.inline - Python gets inline functions
bytecodehacks.macro - Python gets semantic (hygenic) macros!
Please note that these modules are not really bullet-proof, more a
proof-of-concept than anything else.
The are also public domain; do what you like with them. If you find
bugs, or more imaginative uses for these techniques, I'd surely like
to know!
Thanks for taking an interest.

'''CycleHandles are proxies for cycle roots
A CycleHandle subclass should create one or more workers, and pass them
to _set_workers. These workers can then participate in cycles, as long
as deleting all of the worker's attributes will break the cycle. When a
CycleHandle instance goes away, it deletes all attributes of all of
its workers. You could also explicitly call drop_workers.
For example,
>>> class Ham:
... def __del__(self):
... print 'A ham has died!'
...
>>> ct = CycleHandle()
>>> ct._set_workers(Ham(), Ham())
>>> ct._workers[0].ham2 = ct._workers[1]
>>> ct._workers[1].ham1 = ct._workers[0]
>>> del ct
A ham has died!
