  • Can I move beaker.SessionMiddleware to handle method somehow?

    - by Alexander A.Sosnovskiy
    It's a bit ugly that many lines of code fall into "__main__". Can someone give me a tip of how to move SessionMiddleware into handle method? I should notice that I use session in CoreXmlParser. Thanks in advance ! def handle(environ, start_response): req = webob.Request(environ) c = CoreXmlParser(req) resp = webob.Response(body=c(), charset = 'utf-8', status='200 OK', \ request=req, content_type='text/xml') resp(environ, start_response) return resp.app_iter if __name__ == '__main__': #parse config file for session options app = SessionMiddleware(handle, some_session_opts_here) from flup.server.fcgi import WSGIServer WSGIServer(app).run()

  • Can I make TCP/IP session to run less than 60 seconds?

    - by Pavel
    Our server is overloaded with TCP/IP sessions, we have 1200 - 1500 of them. Most of them are hanging in TIME_OUT state. It turns out that a connection in TIME_OUT state occupies a socket until 60 second time-out is elapsed. The problem is that the server gets unresponsive and many clients are not getting served. I have made a simple test: download an XML file from the server with Internet Explorer 8.0 The download finishes in a fraction of second. But then I see that the TCP/IP connection is hanging in TIME_OUT state for 60 seconds. Is there any way to get rid of TIME_OUT waiting or make it less to free the socket for new connections? I understand why TCP/IP connection enters TIME_OUT state, but I don't understand why Internet Explorer does not close the connection after the XML file download is over. The details. Our server runs web service written in Perl (mod-perl). The service provides weather data to clients. Client is a Flash appication (actually Flash ActiveX control embedded in Windows application). Apache "Keep Alive" option is set to 0

  • Can I view a list of public variables of some Adobe Air app or web flash file from another app?

    - by Parris
    I was thinking about creating making AIM pluggin that checks pandora one (desktop) or pandora website periodically to see what is currently playing and update a user's status. I suppose the main question is there a clever way to access a "public" variable from some open Adobe Air process? I KNOW this sounds like some crazy security flaw, but it may also be a feature. I am pretty sure javascript can potentially handle it. Thanks!

  • How can I get the followers of a user on twitter, then get posts from those followers over a period

    - by Ronan
    I've been assigned a research project to enhance social networking based adaptive e-learning and to do so I need to be able to extract several (hundreds, maybe thousands) of status updates or tweets in order to perform factor analysis on key words. Apparently this can be done with javascript but I have never used javascript before so I'm a bit lost. I know I need a Twitter API but not sure even how to use one. Anybody have any idea how I can do this?

  • HTML5 applicationCache in local development

    - by jesper
    I'm experimenting with application cache based on this example: http://html5demos.com/html5demo.manifest This example works fine in ff, but when I create analogous site (almost identical) I get only status "UNCACHED (numeric value 0) -- The ApplicationCache object's cache host is not associated with an application cache at this time." I work on xampp and I've set correct mime-type. When the page is loading ff "is asking to store data on your computer for offline use" and when I show Tools - Options - Advanced - Network - Offline data there is localhost but with 0B size.

  • Core jQuery event modification problem

    - by DSKVR
    I am attempting to overwrite a core jQuery event, in this case the keydown event. My intention is to preventDefault() functionality of Left(37), Up(38), Right(39) and Down(40) to maintain the consistency of hot keys in my web application. I am using the solution provided here for the conditional charCode preventDefault problem. For some reason, my function overwrite is simply not firing, and I cannot put my finger on the problem. I am afraid that over the past 30 minutes this issue has resulted in some hair loss. Anybody have the remedy? /* Modify Keydown Event to prevent default PageDown and PageUp functionality */ (function(){ var charCodes = new Array(37,38,39,40); var original = jQuery.fn.keydown; jQuery.fn.keydown = function(e){ var key=e.charCode ? e.charCode : e.keyCode ? e.keyCode : 0; alert('now why is my keydown mod not firing?'); if($.inArray(key,charCodes)) { alert('is one of them, do not scroll page'); e.preventDefault(); return false; } original.apply( this, arguments ); } })();

  • Are weekly reports necessary?

    - by Dbger
    At the times that we didn't use Scrum, we had weekly status meeting and technical discussion; And now after we adopt Scrum, we have daily stand up meeting. But for both cases, weekly reports are always a necessity, although I don't see much value of doing this in our development team. What do you think of weekly report? what benefit that you got from it if your like it?

  • Infinite Refresh Loop in Firefox 3.0

    - by Martin Gordon
    I'm having a strange issue with my Javascript in Firefox 3.0.x. In Firefox 3.0.12, the page constantly reloads as soon as the list body is loaded. Neither Firefox 3.5, Safari 4 nor Chrome 5 (all on Mac) experience this issue. EDIT: I've created an isolated example rather than pulling this from my existing code. test.js function welcomeIndexOnLoad() { $("#options a").live('click', function () { optionClicked($(this), "get_list_body.html"); return false; }); $(document).ready(function() { optionClicked(null, "get_list_body.html"); }); } function optionClicked(sender, URL) { queryString = ""; if (sender != null) { queryString = $(sender).attr("rel"); } $("#list_body").load(URL + "?" + queryString, function(resp, status, AJAXReq) { console.log(resp); console.log("" + status); location.hash = queryString; }); }? test.html <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js"></script> <script type="text/javascript" src="test.js"></script> <script> welcomeIndexOnLoad(); </script> </head> <body> <div id="container"> Outside of list body. <div id="list_body"> </div> </div> </body> </html> get_list_body.html <h3> <div id="options"> <a href="#" rel="change_list">Change List</a> </div> <ul> <li>li</li> </ul> jQuery line 5252 (an xhr.send() call) shows up in the console as soon as the page reloads: xhr.send( type === "POST" || type === "PUT" || type === "DELETE" ? s.data : null );

  • Redirecting one file to another using dub2 and strtok

    - by Sergiy Zakharov
    OK, here goes. I have to write a program, in which I need to use strtok and dup2 to redirect one file to another, but I need to also have the user to actually put the command cat < file1 file2, but not from the shell, but instead by using my program. That's why I need strtok. And the reason my program doesn't work is probably because of that, because I don't really understand how strtok works. I found a similar program on the internet, but they just take the ls command and redirect it to the file. That's it. My program is much more complicated. I mean, it would've been easier just to say in shell cat < file1 file2, but for some reason they want us to do it this way. So, anyways, here is what I have so far (here I just combined what I have found on the internet with what I already had from before. We had to do something similar but then the user would just go ls or ls -l. Very simple stuff. This is much harder, for me, at least.) #include <fcntl.h> #include <unistd.h> #include <stdio.h> #include <errno.h> #include <sys/wait.h> #include <string.h> int main() { pid_t pid; char line[256]; char *args[129]; int i; int fd; int status; char *temp; while (1) { printf(">"); if (fgets(line, 256, stdin) == 0) { exit(0); } else { pid = fork(); if (pid == 0) { i = 0; temp = strtok("<",line); while (temp != NULL) { args[i++] = temp; temp = strtok(">",line); args[i] = '\0'; } fd = open("hello", O_RDONLY); dup2(fd, STDIN_FILENO); fd = open("world", O_WRONLY|O_CREAT|O_TRUNC, S_IRWXU); dup2(fd, STDOUT_FILENO ); close(fd); execvp(args[0], args); } else { close(fd); wait(&status); } } } } Any help would be greatly appreciated.

  • How to communicate between service controller and a service/daemon?

    - by Sorin Sbarnea
    It is easy to display the status of a Windows service or to control it (start/stop) from a GUI application but the question if how about receiving/sending notifications from the service? Like: service telling to the user monitoring it that it needs attention. Please consider that you can have several controllers started at any time in a multi-user environment. Do you know an example(open source) for this kind of communication? Extra points for a platform independent solution :)

  • Mercurial auto update problem.

    - by Ezequiel
    We are starting to use Mercurial for source control. We have configured the HGRC configuration file to do an auto update after we push to the "central" repository. With some PCs we get this error msg: warning: changegroup hook exited with status -1 HGRC looks like this: [ui] username=ADMIN verbose=true [hooks] changegroup = hg update >&2 Later we perform the update manually and everything works right.
