Hello: I am trying to compile Python 2.5.2 on AIX 5.3 with gcc 4.2.3. I am getting following error. (I also tried Python 2.6 with same error) creating build/temp.aix-5.3-2.5/share/tmhsdsd2/tmp/Python-2.5.2/ Modules gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O3 -Wall - Wstrict-prototypes -I. -I/share/tmhsdsd2/tmp/Python-2.5.2/./Include - I. -IInclude -I./Include -I/usr/local/include -I/share/tmhsdsd2/tmp/ Python-2.5.2/Include -I/share/tmhsdsd2/tmp/Python-2.5.2 -c /share/ tmhsdsd2/tmp/Python-2.5.2/Modules/_struct.c -o build/temp.aix-5.3-2.5/ share/tmhsdsd2/tmp/Python-2.5.2/Modules/_struct.o creating build/lib.aix-5.3-2.5 ./Modules/ld_so_aix gcc -pthread -bI:Modules/python.exp build/ temp.aix-5.3-2.5/share/tmhsdsd2/tmp/Python-2.5.2/Modules/_struct.o -L/ usr/local/lib -lpython2.5 -o build/lib.aix-5.3-2.5/_struct.so collect2: library libpython2.5 not found *** WARNING: renaming "_struct" since importing it failed: 0509-022 Cannot load module build/lib.aix-5.3-2.5. 0509-026 System error: A file or directory in the path name does not exist. error: No such file or directory make: 1254-004 The error code from the last command is 1.

optimization
by Neal Becker Dec. 1, 2008

Dec. 1, 2008

I noticed in some profiling, that it seems that: def Func (): def something(): ... It appears that if Func is called many times, this nested func definition will cause significant overhead. Is this true? I guess I've become accustomed to decent compilers performing reasonable transformations and so have tended to write code for clarity.

I suggest it will likely be worth your time unless you are unalterably opposed to spending money on development products.

HTML File Parsing
by Felipe De Bene Dec. 1, 2008

Dec. 1, 2008

I'm having problems parsing an HTML file with the following syntax : <TABLE cellspacing=0 cellpadding=0 ALIGN=CENTER BORDER=1 width='100%'> <TH BGCOLOR='#c0c0c0' Width='3%'>User ID</TH> <TH Width='10%' BGCOLOR='#c0c0c0'>Name</TH><TH width='7%' BGCOLOR='#c0c0c0'>Date</TH> and so on.... whenever I feed the parser with such file I get the error : Traceback (most recent call last): File "C:\Documents and Settings\Administrator\My Documents\workspace \thread\src\parser.py", line 91, in <module> p.parse(thechange) File "C:\Documents and Settings\Administrator\My Documents\workspace \thread\src\parser.py", line 16, in parse self.feed(s) File "C:\Python25\lib\HTMLParser.py", line 110, in feed self.goahead(0) File "C:\Python25\lib\HTMLParser.py", line 152, in goahead k = self.parse_endtag(i) File "C:\Python25\lib\HTMLParser.py", line 316, in parse_endtag self.error("bad end tag: %r" % (rawdata[i:j],)) File "C:\Python25\lib\HTMLParser.py", line 117, in error raise HTMLParseError(message, self.getpos()) HTMLParser.HTMLParseError: bad end tag: "</TH BGCOLOR='#c0c0c0'>", at line 515, column 45 Googling around I've found a solution to a similar situation, over and over again : http://64.233.169.104/search?q=cache:zOmjwM_sGBcJ:coding.derkeiler.com/pdf/… but coding : you can disable proper parsing by setting the CDATA_CONTENT_ELEMENTS attribute on the parser instance, before you start parsing. by default, it is set to CDATA_CONTENT_ELEMENTS = ("script", "style") setting it to an empty tuple disables HTML-compliant handling for these elements: p = HTMLParser() p.CDATA_CONTENT_ELEMENTS = () p.feed(f.read()) didn't solve my problem. I've made a little modification then to HTMLParser.py instead that solved the problem, as follows: original: endtagfind = re.compile('</\s*([a-zA-Z][-.a-zA-Z0-9:_]*)?(.*) \s*>') my version : endtagfind = re.compile('</\s*([a-zA-Z][-.a-zA-Z0-9:_]*) \s*>') it worked ok for all the files I needed and also for a different file I also parse using the same library. I know it might sound stupid but I was just wondering if there's a better way of solving that problem than just modifying the standard library. Any clue ? thx in advance, Felipe.

double import protection - how to ?
by Helmut Jarausch Dec. 1, 2008

Dec. 1, 2008

Hi, sorry if this is a FAQ (I couldn't find an answer) I have a module which gets imported at several different places not all of which are under my control. How can I achieve that all/some statements within that module get executed only at the very first import? (the statement which must be executed only once, initializes another OS-thread (java in my case)) Many thanks for a hint, Helmut Jarausch Lehrstuhl fuer Numerische Mathematik RWTH - Aachen University D 52056 Aachen, Germany

My mistake. I am sorry to post such a braindead question here. I mistook the host for the url here. Sorry.

setuptools - library dependencies
by redbaron Dec. 1, 2008

Dec. 1, 2008

I try to write setup.py which compiles C Extenstion (A). The problem is the fact, that my C Extension depends on another C lib (B). I've digged it setuptools sources a bit and found "libraries" option for setuptools.setup. Now it compile B library at build_clib stage and A Extenstion at build_ext stage. But it doesn't pack B library in final egg file, only A one. Even more, it compiles B as static lib, but links it to A as dynamic, it leads to undefined symbols in A. How could I either: 1) link A with B staticaly? 2) put B in final egg in same dir as A?

11001, 'getaddrinfo failed' : Error in httplib but not in urllib2
by RajNewbie Dec. 1, 2008

Dec. 1, 2008

Hi all, I am trying to connect to localhost via httplib, but it fails. To check whether it is a firewall problem etc, I tried to connect via urllib2, but it went through fine. Could some one help me out on this? I cannot use urllib2 in the program because I have to send files via post to a url, and urllib2 doesn't support it (Python2.4) Please see the code below: -->HTTPLIB<-- h = httplib.HTTPConnection("http://127.0.0.1:8000") h.request('GET', "/accounts/") res = h.getresponse() -->URLLIB2<-- req = urllib2.Request("http://127.0.0.1:8000/accounts/") fd = urllib2.urlopen(req) Regards Raj
