  • How to solve Python memory leak when using urrlib2?

    - by b_m
    Hi, I'm trying to write a simple Python script for my mobile phone to periodically load a web page using urrlib2. In fact I don't really care about the server response, I'd only like to pass some values in the URL to the PHP. The problem is that Python for S60 uses the old 2.5.4 Python core, which seems to have a memory leak in the urrlib2 module. As I read there's seems to be such problems in every type of network communications as well. This bug have been reported here a couple of years ago, while some workarounds were posted as well. I've tried everything I could find on that page, and with the help of Google, but my phone still runs out of memory after ~70 page loads. Strangely the Garbege Collector does not seem to make any difference either, except making my script much slower. It is said that, that the newer (3.1) core solves this issue, but unfortunately I can't wait a year (or more) for the S60 port to come. here's how my script looks after adding every little trick I've found: import urrlib2, httplib, gc while(true): url = "http://something.com/foo.php?parameter=" + value f = urllib2.urlopen(url) f.read(1) f.fp._sock.recv=None # hacky avoidance f.close() del f gc.collect() Any suggestions, how to make it work forever without getting the "cannot allocate memory" error? Thanks for advance, cheers, b_m update: I've managed to connect 92 times before it ran out of memory, but It's still not good enough. update2: Tried the socket method as suggested earlier, this is the second best (wrong) solution so far: class UpdateSocketThread(threading.Thread): def run(self): global data while 1: url = "/foo.php?parameter=%d"%data s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect(('something.com', 80)) s.send('GET '+url+' HTTP/1.0\r\n\r\n') s.close() sleep(1) I tried the little tricks, from above too. The thread closes after ~50 uploads (the phone has 50MB of memory left, obviously the Python shell has not.) UPDATE: I think I'm getting closer to the solution! I tried sending multiple data without closing and reopening the socket. This may be the key since this method will only leave one open file descriptor. The problem is: import socket s=socket.socket(socket.AF_INET, socket.SOCK_STREAM) socket.connect(("something.com", 80)) socket.send("test") #returns 4 (sent bytes, which is cool) socket.send("test") #4 socket.send("test") #4 socket.send("GET /foo.php?parameter=bar HTTP/1.0\r\n\r\n") #returns the number of sent bytes, ok socket.send("GET /foo.php?parameter=bar HTTP/1.0\r\n\r\n") #returns 0 on the phone, error on Windows7* socket.send("GET /foo.php?parameter=bar HTTP/1.0\r\n\r\n") #returns 0 on the phone, error on Windows7* socket.send("test") #returns 0, strange... *: error message: 10053, software caused connection abort Why can't I send multiple messages??

  • Best language for scripting large scale file management

    - by Dan
    The National Park Service's Natural Sounds Program collects multiple terabytes of data each year measuring soundscapes. In your opinion, what is best available scripting language to manage massive amounts of files and file types? We would like to easily design and run efficient user-friendly scripts to search for and retrieve/create copies of files that may be located in different directories according a single static hierarchy. The OS will most likely be windows. Thanks!

  • How can I stop and start individual websites in IIS using PowerShell?

    - by Joey Green
    I have multiple sites configured in IIS7 on my Windows7 development machine to run on the same port and usually only run one at a time depending on what I'm working on. I would like to be able to start and stop my development sites from PowerShell instead of having the IIS manager opened. Does anyone have a good resource to point me in the right direction or a script that already accomplishes this? Thanks

  • Package SWF into an EXE or APP

    - by Jeremy White
    I am trying to adjust my Flash development workflow so that I am using Flash Builder for all of my coding and multiple FLA files for the user interfaces. I will be creating an ActionScript project in Flash Builder and then having each FLA export a SWC into a resources folder. It is important that I retain the ability to export PC and Mac -- EXE and app, respectively -- projector files. Is there a way of doing this with the Flash compiler or any 3rd party tools?

  • What features would you like to see removed from C++?

    - by Justin Ethier
    This question was inspired by what-features-would-you-like-to-see-added-to-c. anBasically, C++ is a great general-purpose language. But perhaps too general and feature-rich... multiple inheritance, operator overloading, manual memory management, templates, smart pointers, virtual destructors, legacy frameworks (think MFC), and I could just go on. Is there any one feature / aspect of C++ that you would like taken away, to make our lives easier as C++ developers? One feature per answer, please.

  • How to select records as columns in SQL

    - by Leigh
    Hi, I have two tables: tblSizes and tblColors. tblColors has columns called ColorName, ColorPrice and SizeID. There is one size to multiple colors.

The colors must be returned as columns, for instance: SizeID : Width : Height : Red : Green : Blue 1---------220-----220----£15----£20-----£29 Hope this makes sense Thank you

  • How to simulate a dial-up connection for testing purposes?

    - by mawg
    I have to code a server app where clients open a TCP/IP socket, send some data and close the connection. The data packets are small < 100 bytes, however there is talk of having them batch their transactions and send multiple packets. How can I best simulate a dial-up ut connection (using Delphy & Indy components, just FYI)? Is it as simple as open connection wait a while (what is the definition of "a while"?) close connection

  • Is there any way to sync the scrollbars in a JavaFX 1.2 ListView?

    - by Xystus7777
    I have multiple listviews sidebyside. I have a way to make sure the "selectedIndex" is the same on all of them, but is there a way to make it so the scrollbar's are ALWAYS synchronized? It seems that the scrollbars WILL be synced as long as the user uses the ARROW KEYS when navigating down the listview, however, if the user HOLDS DOWN the key, OR USES THE MOUSE WHEEL, they will not be synchronized at all. Thanks in advance! Andrew Davis NASA - Kennedy Space Center
