Compiled Java classes parser.
Author: Thomas de Grenier de Latour (TGL) <[email protected]>
Creation: 2006/11/01
Last-update: 2006/11/06
Introduction:
* This parser is for compiled Java classes, aka .class files. What is nice
with this format is that it is well documented in the official Java VM specs.
* Some fields, and most field sets, have dynamic sizes, and there is no offset
to directly jump from an header to a given section, or anything like that.
It means that accessing a field at the end of the file requires that you've
already parsed almost the whole file. That's not very efficient, but it's
okay given the usual size of .class files (usually a few KB).
* Most fields are just indexes of some "constant pool" entries, which holds
most constant datas of the class. And constant pool entries reference other
constant pool entries, etc. Hence, a raw display of this fields only shows
integers and is not really understandable. Because of that, this parser
comes with two important custom field classes:
- CPInfo are constant pool entries. They have a type ("Utf8", "Methodref",
etc.), and some contents fields depending on this type. They also have a
"__str__()" method, which returns a syntetic view of this contents.
- CPIndex are constant pool indexes (UInt16). It is possible to specify
what type of CPInfo they are allowed to points to. They also have a
custom display method, usually printing something like "-> foo", where
foo is the str() of their target CPInfo.
References:
* The Java Virtual Machine Specification, 2nd edition, chapter 4, in HTML:
http://java.sun.com/docs/books/vmspec/2nd-edition/html/ClassFile.doc.html
=> That's the spec i've been implementing so far. I think it is format
version 46.0 (JDK 1.2).
* The Java Virtual Machine Specification, 2nd edition, chapter 4, in PDF:
http://java.sun.com/docs/books/vmspec/2nd-edition/ClassFileFormat.pdf
=> don't trust the URL, this PDF version is more recent than the HTML one.
It highligths some recent additions to the format (i don't know the
exact version though), which are not yet implemented in this parser.
* The Java Virtual Machine Specification, chapter 4:
http://java.sun.com/docs/books/vmspec/html/ClassFile.doc.html
=> describes an older format, probably version 45.3 (JDK 1.1).
TODO/FIXME:
* Google for some existing free .class files parsers, to get more infos on
the various formats differences, etc.
* Write/compile some good tests cases.
* Rework pretty-printing of CPIndex fields. This str() thing sinks.
* Add support of formats other than 46.0 (45.3 seems to already be ok, but
there are things to add for later formats).
* Make parsing robust: currently, the parser will die on asserts as soon as
something seems wrong. It should rather be tolerant, print errors/warnings,
and try its best to continue. Check how error-handling is done in other
parsers.
* Gettextize the whole thing.
* Check whether Float32/64 are really the same as Java floats/double. PEP-0754
says that handling of +/-infinity and NaN is very implementation-dependent.
Also check how this values are displayed.
* Make the parser edition-proof. For instance, editing a constant-pool string
should update the length field of it's entry, etc. Sounds like a huge work.

We don't handle the following:
1. Cache-Control: max-stale

Not that this algorithm is simpler than you might think
because we are operating as a private (non-shared) cache.
This lets us ignore 's-maxage'. We can also ignore
'proxy-invalidate' since we aren't a proxy.
We will never return a stale document as
fresh as a design decision, and thus the non-implementation
of 'max-stale'. This also lets us safely ignore 'must-revalidate'
since we operate as if every server has sent 'must-revalidate'.
Since we are private we get to ignore both 'public' and
'private' parameters. We also ignore 'no-transform' since
we don't do any transformations.
The 'no-store' parameter is handled at a higher level.

============================
JSONRPC Library (jsonrpclib)
============================
This library is a JSON-RPC v.2 (proposed) implementation which
follows the xmlrpclib API for portability between clients. It
uses the same Server / ServerProxy, loads, dumps, etc. syntax,
while providing features not present in XML-RPC like:
* Keyword arguments
* Notifications
* Versioning
* Batches and batch notifications
Eventually, I'll add a SimpleXMLRPCServer compatible library,
and other things to tie the thing off nicely. :)
For a quick-start, just open a console and type the following,
replacing the server address, method, and parameters
appropriately.
>>> import jsonrpclib
>>> server = jsonrpclib.Server('http://localhost:8181')
>>> server.add(5, 6)
11
>>> server._notify.add(5, 6)
>>> batch = jsonrpclib.MultiCall(server)
>>> batch.add(3, 50)
>>> batch.add(2, 3)
>>> batch._notify.add(3, 5)
>>> batch()
[53, 5]
See http://code.google.com/p/jsonrpclib/ for more info.

Otherwise, no such check takes place.

JavaScript syntax (ECMA-262 3rd edition) used as a lightweight data
interchange format.
:mod:`simplejson` exposes an API familiar to users of the standard library
:mod:`marshal` and :mod:`pickle` modules. It is the externally maintained
version of the :mod:`json` library contained in Python 2.6, but maintains
compatibility with Python 2.4 and Python 2.5 and (currently) has
significant performance advantages, even without using the optional C
extension for speedups.
Encoding basic Python object hierarchies::
>>> import simplejson as json
>>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
'["foo", {"bar": ["baz", null, 1.0, 2]}]'
>>> print json.dumps("\"foo\bar")
"\"foo\bar"
>>> print json.dumps(u'\u1234')
"\u1234"
>>> print json.dumps('\\')
"\\"
>>> print json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True)
{"a": 0, "b": 0, "c": 0}
>>> from StringIO import StringIO
>>> io = StringIO()
>>> json.dump(['streaming API'], io)
>>> io.getvalue()
'["streaming API"]'
Compact encoding::
>>> import simplejson as json
>>> json.dumps([1,2,3,{'4': 5, '6': 7}], separators=(',',':'))
'[1,2,3,{"4":5,"6":7}]'
Pretty printing::
>>> import simplejson as json
>>> s = json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4)
>>> print '\n'.join([l.rstrip() for l in s.splitlines()])
{
"4": 5,
"6": 7
}
Decoding JSON::
>>> import simplejson as json
>>> obj = [u'foo', {u'bar': [u'baz', None, 1.0, 2]}]
>>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]') == obj
True
>>> json.loads('"\\"foo\\bar"') == u'"foo\x08ar'
True
>>> from StringIO import StringIO
>>> io = StringIO('["streaming API"]')
>>> json.load(io)[0] == 'streaming API'
True
Specializing JSON object decoding::
>>> import simplejson as json
>>> def as_complex(dct):
... if '__complex__' in dct:
... return complex(dct['real'], dct['imag'])

The relativedelta type is based on the specification of the excelent
work done by M.-A. Lemburg in his mx.DateTime extension. However,
notice that this type does *NOT* implement the same algorithm as
his work. Do *NOT* expect it to behave like mx.DateTime's counterpart.
There's two different ways to build a relativedelta instance. The
first one is passing it two date/datetime classes:
relativedelta(datetime1, datetime2)
And the other way is to use the following keyword arguments:
year, month, day, hour, minute, second, microsecond:
Absolute information.
years, months, weeks, days, hours, minutes, seconds, microseconds:
Relative information, may be negative.
weekday:
One of the weekday instances (MO, TU, etc). These instances may
receive a parameter N, specifying the Nth weekday, which could
be positive or negative (like MO(+1) or MO(-2). Not specifying
it is the same as specifying +1. You can also use an integer,
where 0=MO.
leapdays:
Will add given days to the date found, if year is a leap
year, and the date found is post 28 of february.
yearday, nlyearday:
Set the yearday or the non-leap year day (jump leap days).
These are converted to day/month/leapdays information.
Here is the behavior of operations with relativedelta:
1) Calculate the absolute year, using the 'year' argument, or the
original datetime year, if the argument is not present.
2) Add the relative 'years' argument to the absolute year.
3) Do steps 1 and 2 for month/months.
4) Calculate the absolute day, using the 'day' argument, or the
original datetime day, if the argument is not present. Then,
subtract from the day until it fits in the year and month
found after their operations.
5) Add the relative 'days' argument to the absolute day. Notice
that the 'weeks' argument is multiplied by 7 and added to
'days'.
6) Do steps 1 and 2 for hour/hours, minute/minutes, second/seconds,
microsecond/microseconds.
7) If the 'weekday' argument is present, calculate the weekday,
with the given (wday, nth) tuple. wday is the index of the
weekday (0-6, 0=Mon), and nth is the number of weeks to add
forward or backward, depending on its signal. Notice that if
the calculated date is already Monday, for example, using
(0, 1) or (0, -1) won't change the day.

This method was ported from the work done by GM Arts,
on top of the algorithm by Claus Tondering, which was
based in part on the algorithm of Ouding (1940), as
quoted in "Explanatory Supplement to the Astronomical
Almanac", P. Kenneth Seidelmann, editor.
This algorithm implements three different easter
calculation methods:
1 - Original calculation in Julian calendar, valid in
dates after 326 AD
2 - Original method, with date converted to Gregorian
calendar, valid in years 1583 to 4099
3 - Revised method, in Gregorian calendar, valid in
years 1583 to 4099 as well
These methods are represented by the constants:
EASTER_JULIAN = 1
EASTER_ORTHODOX = 2
EASTER_WESTERN = 3
The default method is method 3.
More about the algorithm may be found at:
http://users.chariot.net.au/~gmarts/eastalg.htm
