Hi,
I'm trying to parse some binary data with regexes. It works well in
the latest Python build, but I need to run this on Python 1.5.2. The
binary data has a pattern like this:
keyName1\002..( .*)\000.*keyNam e2\002..(.*)\00 0
(I'm using regex syntax to illustrate)
So I wrote the following script:
def amfKey(str):
return "%s\002..([^\000]*)" % str
keys = re.compile(amfK ey("key"), re.DOTALL).find all(amfStr)
Works on 2.3.3, but produces the following error on 1.5.2:
Traceback (innermost last):
File "test.py", line 26, in ?
keys = re.compile(amfK ey("key"), re.DOTALL).find all(amfStr)
File "C:\Python152\L ib\re.py", line 79, in compile
code=pcre_compi le(pattern, flags, groupindex)
TypeError: argument 1: expected string without null bytes, string found
Does anyone know a workaround? The type of binary data I'm trying to
parse is AMF (Action Message Format), Macromedia's proprietary format
for fast communication between the Flash Player and their "Flash
Remoting" servers (ColdFusion/.NET/Java implementations ). But there
are opensource "Flash Remoting" implementations in PHP (amfphp.org),
Perl (simonf.com/flap/) and Java (openamf.org) already - I've
started to work on the Python port.
And I wanted to keep this Python 1.5.2-compatible...
Thanks in advance,
=-

I'm working on writing a program that will synchronize one database with
another. For the source database, we can just use the python sybase API;
that's nice and normal.
For the target database, unfortunately, the only interface we have access
to, is http+html based. There's same javascript involved too, but
hopefully we won't have to interact with that.
So, I've got Basic AUTH going with http, but now I'm faced with the

Hi
I have an .Net application which processes thousands of Xml nodes each
day and for each node I am using around 30-40 Regex matches to see if
they satisfy some conditions are not. These Regex matches are called
within a loop (like if or for). E.g.
for(int i = 0; i < 10; i++)
{
Regex r = new Regex();

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
