python - QNetworkReply doesn't abort/close -


edit:

i've prepared sscce convenience: (just run it)

from pyqt4 import qtcore, qtgui, qtnetwork pyqt4.qtcore import * pyqt4.qtgui import * pyqt4.qtnetwork import qnetworkaccessmanager, qnetworkrequest, qnetworkreply import time import sys import json  try:     _fromutf8 = qtcore.qstring.fromutf8 except attributeerror:     def _fromutf8(s):         return s  class sscce(object):     def setupui(self, mainwindow):         mainwindow.setobjectname(_fromutf8("mainwindow"))         mainwindow.resize(800, 578)         qmetaobject.connectslotsbyname(mainwindow)      def main(self):         request = qnetworkrequest()         request.seturl(qurl("http://search.twitter.com/search.json?q=blue&rpp=1"))          self.network_manager = qnetworkaccessmanager()         self.network_manager.finished.connect(self._request_finished)                  self.network_manager.post(request, self.urlencode_post({'a' : 'b'}))      def urlencode_post(self, data):         post_params = qurl()         (key, value) in data.items():             post_params.addqueryitem(key, unicode(value))                      return post_params.encodedquery()      def func2(self):         request = qnetworkrequest()         request.seturl(qurl("http://search.twitter.com/search.json?q=red&rpp=1"))         request.setrawheader('content-type', 'application/x-www-form-urlencoded;charset=utf-8')         self.network_manager.finished.connect(self.func3)         self.network_manager.get(request)      def func3(self, reply):         if not reply.error() == qnetworkreply.noerror:             # request failed             print(reply.error())             print(reply.errorstring())         else:             reply.close()      def func1(self, reply):         ans = reply.readall()         print(ans)         time.sleep(5)         print("""\n  prints them both: =================== %s """%ans)         self.func2()      def _request_finished(self, reply):         if not reply.error() == qnetworkreply.noerror:             # request failed             print(reply.error())             print(reply.errorstring())         else:             reply.close()             self.func1(reply)   app = qapplication(sys.argv) mainwindow = qmainwindow() ui = sscce() ui.setupui(mainwindow) ui.main()  mainwindow.show() sys.exit(app.exec_())

original question:

my code: (relevent parts)

    def update(self):         request = qnetworkrequest()         request.seturl(qurl("someurl"))         self.network_manager.finished.connect(self._update)         self.network_manager.get(request)      def _update(self, reply): # update stage 2             if not reply.error() == qnetworkreply.noerror:             # request failed             print(reply.error())             print(reply.errorstring())             print("retrying")             self.update()         else:             reply.abort()             #print(str(reply.readall().data()))             data = json.loads(str(reply.readall().data())) # data             #work data (irrelevant)      def sendbearer_req(self):          request = qnetworkrequest()         request.seturl(qurl("someotherurl"))          self.network_manager = qnetworkaccessmanager()         self.network_manager.finished.connect(self._request_finished)                  self.network_manager.post(request, self.urlencode_post({'some' : 'thing'}))      def sendbearer(self, reply):         reply.abort()         ans = reply.readall()                 print(ans)         time.sleep(5)         print(ans)          try:             self.bearer = json.loads(str(ans))                             self.update()                     except:             raise #for debugging             self.sendbearer_req() #retry              def _request_finished(self, reply):         if not reply.error() == qnetworkreply.noerror:             # request failed             print(reply.error())             print(reply.errorstring())             print("retrying")             self.sendbearer_req()         else:             self.sendbearer(reply)

problem:

in part:

reply.abort() ans = reply.readall()         print(ans) time.sleep(5) print(ans)

i'm pretty sure abort isn't working because on first print prints want then, while waits, apparently continues code , enters update function sends request. therefor in second print 2 replies mix , prints both.

(btw tried close - same result)

what doing wrong?

i found problem!

the problem haven't disconnected network manager finished signal former function connected to, therefore causing reply go both functions (new connection , old one)

i solved using .disconnect() command before connecting again:

self.network_manager.finished.disconnect() #this!!! self.network_manager.finished.connect(self._update)

and in sscce:

self.network_manager.finished.disconnect() #this!!! self.network_manager.finished.connect(self.func3)

hope helped future viewers!

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
