Please show your code, here.  urllib doesn't always return full content

The backslash '\' is a meta-char that escapes the string.  You can
escape the char as following string
u"\\u'
insert another '\' before it.

Why not try to create a file object with bufsize = 0 ?

-

"import" imports bindings between symbols and objects into
the module from another one. When you call a function in another
module, it changes global space of module where it is defined.
The global space of the module, where caller is in, is kept from touched
except accessing through module names.

This is amount of memory allocate by process not Python interpreter.
It is managemed by
malloc() of C library. When you free a block memory by free()
function, it only return
the memory to C library for later use, but C library not always return
the memory to
the kernel.

Since there is a virtual memory for modem OS, inactive memory will be
paged
to pager when more physical memory blocks are need. It don't hurt
much if you have enough
swap space.

What you get from ps command is memory allocated by process, it don't
means
they are used by Python interpreter.

Why don't you just define HelloWindow as a function? It is more simple.
If you want HelloWindow() to return the object from glade, you can
make HelloWindow as a function or
a class with __new__() method, suggested by Sylvain's, that return a
object from glade.

for ex:
def HelloWindow():
..
return xml.get_widget("window")
pass

or
class HelloWindow:
def __init__(self):
pass
def __new__(clz, *args):

return xml.get_widget("window")

Do you want to call constructor of super-class to initialize the object?
If it is true, you have following options.

In old style class:
class MyClass(ParentClass):
def __init__(self):
ParentClass.__init__(self)

In new style class:
class MyClass(ParentClass):
def __init__(self):
super(MyClass).__init__(self)

Or
class MyClass(ParentClass):
def __init__(self):
super(MyClass, self).__init__()

No, Python is executing a module. You should explicit call __main__()
at top scope of
your module. For ex.

if __name__ == '__main__':
__main__()

This snippet calls __main__() when the module is executed directly,
but not imported as a module.

Once a module had been imported, you should invoke reload() function
to reload it from filesystem.

You have better set LD_LIBRARY_PATH environment variable, or use
ldconfig (plz, man ldconfig)
to add the directory, where you shared object is in, to the search
path of dynamic linker.

Since you create a new module, you should try to link your module with
- -rpath-link option.
You can specify a path searched by linker when finding shared object
required.

Does child-process terminate it-self in a very short time ?
It can be a race condition, here.
You can try to sleep for a while in child-process to make sure parent
being executed. Parent process may not schedule to run immediately
after spawn. And, you can print some thing before os.spawnl() to make
sure that message can be delivered successfully.

You have missed my idea.
Since os.waitpid will be blocked, you should print your message before

You should flush sys.stdout after you print messages, or

I guess it is caused by ill handling reference count of coord.
You should call Py_INCREF() to get a reference since it is borrowed
from PyArg_ParseTuple().

Since PyArg_ParseTuple() is supposed to parse arguments, I recommand you
to use PyTuple_GetItem() or PyTuple_GET_ITEM(). You can find more
functions
at http://docs.python.org/api/genindex.html .

Yes! Please refer http://docs.python.org/api/arg-parsing.html#l2h-210
And your second PyArg_ParseTuple() call, should not make a reference
on coord.
It should be PyArg_ParseTuple(coord, ...) since you declare coord as a
pointer.
You can add some printf() to throw out messages to make sure where the
program stop at.
If you can compile the module with debug information and use gdb to
backtrace dump file,
it would be useful.

It should be "PyObject *coord;" .
Maybe, it is what is wrong with your program!

ld-elf.so reads environment variables when it was loaded.
It never reads environment variables again!
That you setting environment in the process does not make link-editor
to re-read environment variable and take effect.

To resolve the problem, you can try to add the path to sys.path.

find code like

def setencoding():
"""Set the string encoding used by the Unicode implementation. The
default is 'ascii', but if you're willing to experiment, you can
change this."""
encoding = "ascii" # Default value set by _PyUnicode_Init()
if 0:
# Enable to support locale aware default string encodings.
import locale
loc = locale.getdefaultlocale()
if loc[1]:
encoding = loc[1]

in site.py . and change if 0: to if 1: to enable string encoding.
Now, you can execute python interpreter with LC_CTYPE='UTF-8'.

What you want is something like 'tail -f' in linux.
If you look into it's source code, you will find it check file periodically.
When a read() reach the end of the file, read() will return a empty string.
You can try to read data from the file periodically after a EOF.
I think it is what you want.

another SQL implement

[Thinker]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

hello,

I have implement a SQL command generator for Python. It uses features
and syntax of Python to describe SQL schema & query. Following is a
example:

from pysqlite2 import dbapi2 as sqlite
from pysql import *

#
# define data source
# comprises tables and queries
#
class my_data_src(data_src):
def ds_definition():
class t1(pysql.table):
#
# define table 't1'
#
item = pysql.str_f()
count = pysql.int_f()
pass

class t2(pysql.table):
#
# define table 't2'
#
item = pysql.str_f()
money = pysql.float_f()
pass

#
# define a query 'get_count_and_money_of_item'
#
get_count_and_money_of_item = \
lambda: (t1 * t2) \
.fields(t1.item, t1.count * t2.money - 30) \
.where((t1.item == t2.item) & (t1.item != pysql._q))

return ds_define()
pass

cx = sqlite.connect('test
<http://heaven.branda.to/%7Ethinker/GinGin_CGI.py/show_kw_docs/test>.db')

db = my_data_src(cx) # create a instance of data source

db.init_db() # create tables

db.insert(db.t1, item='foo', count=100)
db.insert(db.t2, item='foo', money=3.2)
db.insert(db.t1, item='boo', count=50)
db.insert(db.t2, item='boo', money=3.0)

db.update(db.t1, count=140, where=~(db.t1.item == 'foo'))

cu = db.get_count_and_money_of_item('foo')
rows = cu.fetchall()
print rows

cu = db.get_count_and_money_of_item('cool')
rows = cu.fetchall()
print rows

db.commit()

pass

This is example code to define database schema and query.
get_count_and_money_of_item is initialized by a lambda expression. It
can also be a function. By inherit class data_src and defining method
ds_definition, my_data_src is acting as a wrapper of a database. It
includes two tables, t1 & t2, and a query,
get_count_and_money_of_item. Instantiate a instance of my_data_src
with a DB connection, you can create tables (init_db), insert records,
update records, and perform queries.

get_count_and_money_of_item = \
lambda: (t1 * t2) \
.fields(t1.item, t1.count * t2.money - 30) \
.where((t1.item == t2.item) & (t1.item != pysql._q))

(t1 * t2) means join tables t1 & t2, you can specify fields to be
return by query with *.fields(...). *.where() is just like WHERE
expression in SQL. get_count_and_money_of_item comprises a
free-variable; pysql._q stands as a free-variable waiting for caller
specified as parameter when calling get_count_and_money_of_item.

cu = db.get_count_and_money_of_item('foo')
rows = cu.fetchall()

It calls get_count_and_money_of_item() with 'foo' for free-variable.
A query returns a cursor defined in DBAPI.

Why another SQL ? Why not SQLObject?
RDBMS provides powerful query language, it provides performance by
reducing traffic between database & application and reducing memory
copy. A OR-mapping made RDBMS weak. DBMS is reduced as a indexed
storage. Relational algebra is so powerful & effective. Why don't
integrate it into Python language?

Downloads:
The implementation depend on pythk, so you need two modules, pysql & pythk

What is your OS? Maybe you should show out the memory usage of your python
process. In FreeBSD, you should set evironment variable
'MALLOC_OPTIONS=P' to
print out usage of malloc()。Maybe you can find a way, in your system,
to print out usage of the
heap.
