• dump csv from sqlalchemy

  - by afilatun

  For some reason, I want to dump a table from a database (sqlite3) in the form of a csv file. I'm using a python script with elixir (based on sqlalchemy) to modify the database. I was wondering if there is any way to dump the table I use to csv. I've seen sqlalchemy serializer but it doesn't seem to be what I want. Am I doing it wrong? Should I call the sqlite3 python module after closing my sqlalchemy session to dump to a file instead? Or should I use something homemade?

• How to make socket.listen(1) work for some time and then continue rest of code???

  - by Rami Jarrar

  I'm making server that make a tcp socket and work over port range, with each port it will listen on that port for some time, then continue the rest of the code. like this:: import socket sck = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sck.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) msg ='' ports = [x for x in xrange(4000)] while True: try: for i in ports: sck.bind(('',i)) ## sck.listen(1) ## make it just for some time and then continue this ## if there a connection do this conn, addr = sck.accept() msg = conn.recv(2048) ## do something ##if no connection continue the for loop conn.close() except KeyboardInterrupt: exit() so how i could make sck.listen(1) work just for some time ??

• SQL Server join and wildcards

  - by Ernst

  I want to get the results of a left join between two tables, with both having a column of the same name, the column on which I join. The following query is seen as valid by the import/export wizard in SQL Server, but it always gives an error. I have some more conditions, so the size wouldn't be too much. We're using SQL Server 2000 iirc and since we're using an externally developed program to interact with the database (except for some information we can't retrieve that way), we can not simply change the column name. SELECT table1.*, table2.* FROM table1 LEFT JOIN table2 ON table1.samename = table2.samename At least, I think the column name is the problem, or am I doing something else wrong?

• Why can't I get Python's urlopen() method to work?

  - by froadie

  Why isn't this simple Python code working? import urllib file = urllib.urlopen('http://www.google.com') print file.read() This is the error that I get: Traceback (most recent call last): File "C:\workspace\GarchUpdate\src\Practice.py", line 26, in <module> file = urllib.urlopen('http://www.google.com') File "C:\Python26\lib\urllib.py", line 87, in urlopen return opener.open(url) File "C:\Python26\lib\urllib.py", line 206, in open return getattr(self, name)(url) File "C:\Python26\lib\urllib.py", line 345, in open_http h.endheaders() File "C:\Python26\lib\httplib.py", line 892, in endheaders self._send_output() File "C:\Python26\lib\httplib.py", line 764, in _send_output self.send(msg) File "C:\Python26\lib\httplib.py", line 723, in send self.connect() File "C:\Python26\lib\httplib.py", line 704, in connect self.timeout) File "C:\Python26\lib\socket.py", line 514, in create_connection raise error, msg IOError: [Errno socket error] [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond I've tried it with several different pages but I can never get the urlopen method to execute correctly.

• How to apply a free third party CA and set up Tomcat SSL with it

  - by lenny

  These days I tried to apply a free third pary CA ( www.cacert.org & www.freeca.cn ) and then set up Tomcat SSL with the CA. My purpose is to eliminate the "Certificate Error" page when accessing https://... from a client browser. But it's a little hard for me to get around it.

• Python: wxpython wx.media.MediaCtrl - millisecond seek capability

  - by PPTim

  I've been searching for a media player that can display sub-second resolution in videos. Some pointed me to the Frame stepping functionality in MPC, but I'd like even more than that. I know from previous experience with wxPython that the wx.media.MediaCtrl both displays and (as fast as i can click with the mouse anyway) stops the video with millisecond-precision. The code is here, and runs no-problem with python +wxpython module. Has anyone come across other video players that handle this functionality, or has seen a more robust/developed video player written with wxPython that allows for this level of precision? This is possibily a one-off task so I'd like to use existing solutions if possible. Thanks.

• need help with installing shared libraries on linux

  - by naiquevin

  Hi, I am new to linux and trying to get the Ajax Push engine server to work on Ubuntu 9.04. I installed the server from source it fails the check that it does by using its own javascript framework. The problem is that it fails to load the modules and the output that i get in the terminal when i start it is. [Module] Failed to load ../modules/lib/libmod_spidermonkey.so [Invalid library] (libmysac.so.0.0: cannot open shared object file: No such file or directory) i thought i had to install mysac lib as a shared lib, so after some searching i copied the libmysac.so to /usr/local/lib/ and upon running ldconfig there it created the symlink. But still it gived the same error. Now I copied the libmod_spidermonkey.so in the shared lib dir. But this time ldconfig did not create any symlinks. I am really confused and looking for some pointers . Please help

• I want to version control my entire slice

  - by Tom

  I'm renting a slice (i.e., a VPS) from Slicehost. I've a spent a day or two filling up /usr with my favorite packages, /etc with configs and init scripts, and so on. Now I want to: save this whole setup somewhere (e.g., to load onto another machine). see what changes I've made to which files revert changes, tag revisions, and all that other good version control stuff Saving a disk image gives me (1), but not (2) and (3). Using Subversion (svn import / svn://someotherhost) might give me all three, but I expect problems if I actually try to check a project out into / and maintain .svn directories in root-owned areas. And to load my setup onto a fresh slice, I'd need to install an svn client on it first. Is there a good way to do what I want to do?

• Convert xs:Enumerations in XSD to dropdown lists in Excel

  - by ashwnacharya

  I have an XSD file which contains the schema for my XML. The XSD file contains an xs:Enumeration definition, which allows me to choose between 5 options as a value for one of the nodes. Now, we want to be able to generate this data through Excel, so that non techie people can create it... When I import this XSD file into Excel, i want the xs:enumeration values to be listed as dropdowns. How do I get to do that? Edit: Starting a bounty. To win, I need a working sample code for this :)

• how to remove a few lines from a Unicode registry file using batch commands in Windows?

  - by Cosmin

  Hi. I have a program who's generating some data in registry. I save it with "reg export HKCU\Software\ProgramName\Data data.reg" (Unicode format). I need to take it to other computer and import it there so the program from that computer could use the data. But I have to remove some text lines from data.reg. The text lines are easy to find because they contain some strings. Now I'm doing this manually (using Wordpad) every few days but maybe there is another way... Oh and I can't install other programs on these computers (the access is restricted) so I have to use batch/cmd files. What I tried so far: - redirecting the export to "con" but is visual only not in a variable; - using "for /F ..." but this works only with ANSI and removes blank lines. Can somebody please help me...? Thank you.

• Best way to structure AJAX for a Zend Framework application

  - by John Nall

  Sorry, but there's a lot of outdated and just plain bad information for Zend Framework, since it has changed so much over the years and is so flexible. I thought of having an AJAX module service layer, with controllers and actions that interact with my model. Easy, but not very extensible and would violate DRY. If I change the logistics of some process I'll have to edit the AJAX controllers and the normal controllers. So ideally I would load the exact same actions for both javascript and non-javascript users. I have thought about maybe checking for $_POST['ajax'], if it is set I would load a different (json'y) view for the data. Was wondering how/a good way to do this (front controller plugin I imagine?) or if someone can point me to an UP TO DATE tutorial that describes a really good way for building a larger ajax application. thx

• Set top level directory to be handled by Perl?

  - by Sam Lee

  I have an Apache server set up to use mod_perl. I have it set up to handle all requests using a Perl module MyModule. Here is part of my httpd.conf: LoadModule perl_module modules/mod_perl.so <Directory /> Order Deny,Allow Allow from all </Directory> PerlModule MyModule <Location /> SetHandler modperl PerlResponseHandler MyModule </Location> This seems to work fine, except top level directory (ie. www.mysite.com/) is not being sent to MyModule. What's going wrong?

• Processing file uploads before object is saved

  - by Dominic Rodger

  I've got a model like this: class Talk(BaseModel): title = models.CharField(max_length=200) mp3 = models.FileField(upload_to = u'talks/', max_length=200) seconds = models.IntegerField(blank = True, null = True) I want to validate before saving that the uploaded file is an MP3, like this: def is_mp3(path_to_file): from mutagen.mp3 import MP3 audio = MP3(path_to_file) return not audio.info.sketchy Once I'm sure I've got an MP3, I want to save the length of the talk in the seconds attribute, like this: audio = MP3(path_to_file) self.seconds = audio.info.length The problem is, before saving, the uploaded file doesn't have a path (see this ticket, closed as wontfix), so I can't process the MP3. I'd like to raise a nice validation error so that ModelForms can display a helpful error ("You idiot, you didn't upload an MP3" or something). Any idea how I can go about accessing the file before it's saved? p.s. If anyone knows a better way of validating files are MP3s I'm all ears - I also want to be able to mess around with ID3 data (set the artist, album, title and probably album art, so I need it to be processable by mutagen).

• Multiple levels of 'collection.defaultdict' in Python

  - by Morlock

  Thanks to some great folks on SO, I discovered the possibilities offered by collections.defaultdict, notably in readability and speed. I have put them to use with success. Now I would like to implement three levels of dictionaries, the two top ones being defaultdict and the lowest one being int. I don't find the appropriate way to do this. Here is my attempt: from collections import defaultdict d = defaultdict(defaultdict) a = [("key1", {"a1":22, "a2":33}), ("key2", {"a1":32, "a2":55}), ("key3", {"a1":43, "a2":44})] for i in a: d[i[0]] = i[1] Now this works, but the following, which is the desired behavior, doesn't: d["key4"]["a1"] + 1 I suspect that I should have declared somewhere that the second level defaultdict is of type int, but I didn't find where or how to do so. The reason I am using defaultdict in the first place is to avoid having to initialize the dictionary for each new key. Any more elegant suggestion? Thanks pythoneers!

• Fatal Error when using ADODB in VB6 on Windows Server 2003 SP2

  - by m.edmondson

  We've got a legacy app (VB6) which works fine on an old Windows Server 2003 box and has been for many years. Recently we've had to move it to a different physical location and in doing this we cloned the box with virtualisation and placed it elsewhere. In theory these two environments should be identical. On the new box however the app falls over when calling the RecordCount method of an ADODB.Recordset. I should say that I can successfully read the ADODB.RecordSet.Properties.Count property with no problem on the line before. The event viewer reports the following: Event Type: Error Event Source: Application Error Event Category: (100) Event ID: 1000 Date: 28/09/2012 Time: 11:15:27 User: N/A Computer: APP01 Description: Faulting application Control.exe, version 1.0.0.6, faulting module ntdll.dll, version 5.2.3790.4789, fault address 0x0002c6e4. I can only imagine there is something wrong with using ADODB within a virtualised environment. Any ideas?

• Python ValueError: not allowed to raise maximum limit

  - by Ricky Bobby

  I'm using python 2.7.2 on mac os 10.7.3 I'm doing a recursive algorithm in python with more than 50 000 recursion levels. I tried to increase the maximum recursion level to 1 000 000 but my python shell still exit after 18 000 recursion levels. I tried to increase the resources available : import resource resource.setrlimit(resource.RLIMIT_STACK, (2**29,-1)) sys.setrecursionlimit(10**6) and I get this error : Traceback (most recent call last): File "<pyshell#58>", line 1, in <module> resource.setrlimit(resource.RLIMIT_STACK,(2**29,-1)) ValueError: not allowed to raise maximum limit I don't know why I cannot raise the maximum limit ? thanks for your suggestions .

• Named semaphores in Python?

  - by Boaz

  Hi, I have a script in python which uses a resource which can not be used by more than a certain amount of concurrent scripts running. Classically, this would be solved by a named semaphores but I can not find those in the documentation of the multiprocessing module or threading . Am I missing something or are named semaphores not implemented / exposed by Python? and more importantly, if the answer is no, what is the best way to emulate one? Thanks, Boaz PS. For reasons which are not so relevant to this question, I can not aggregate the task to a continuously running process/daemon or work with spawned processed - both of which, it seems, would have worked with the python API.

• How do you sort files numerically?

  - by Zachary Young

  Hello all, First off, I'm posting this because when I was looking for a solution to the problem below, I could not find one on stackoverflow. So, I'm hoping to add a little bit to the knowledge base here. I need to process some files in a directory and need the files to be sorted numerically. I found some examples on sorting--specifically with using the lamba pattern--at wiki.python.org, and I put this together: #!env/python import re tiffFiles = """ayurveda_1.tif ayurveda_11.tif ayurveda_13.tif ayurveda_2.tif ayurveda_20.tif ayurveda_22.tif""".split('\n') numPattern = re.compile('_(\d{1,2})\.', re.IGNORECASE) tiffFiles.sort(cmp, key=lambda tFile: int(numPattern.search(tFile).group(1))) print tiffFiles I'm still rather new to Python and would like to ask the community if there are any improvements that can be made to this: shortening the code up (removing lambda), performance, style/readability? Thank you, Zachary

• Any way to run DLL's at button click C#

  - by Sandeep Bansal

  Hi Guys, I'm looking for ways to speed my program to the max and one way I thought of was to strip all DLL's being run at startup and run them when they need to be. As an example, I have a DLL containing info required for an update module, but I don't want to have that running in the program if I don't need it till I have an update. (I know I can create a separate program and link it to that but this is just an example.) Is there anyway to attach this on a button click? Sorry if I haven't made my question understandable. Thanks

• Sort by an object's type

  - by Richard Levasseur

  Hi all, I have code that statically registers (type, handler_function) pairs at module load time, resulting in a dict like this: HANDLERS = { str: HandleStr, int: HandleInt, ParentClass: HandleCustomParent, ChildClass: HandleCustomChild } def HandleObject(obj): for data_type in sorted(HANDLERS.keys(), ???): if isinstance(obj, data_type): HANDLERS[data_type](obj) Where ChildClass inherits from ParentClass. The problem is that, since its a dict, the order isn't defined - but how do I introspect type objects to figure out a sort key? The resulting order should be child classes follow by super classes (most specific types first). E.g. str comes before basestring, and ChildClass comes before ParentClass. If types are unrelated, it doesn't matter where they go relative to each other.

• Can I fill in an encypted PDF with iTextSharp?

  - by Cmpalmer

  I have a fillable, saveable PDF file that has an owner password (that I don't have access to). I can fill it out in Adobe reader, export the FDF file, modify the FDF file, and then import it. Then I tried to do it with iText(Sharp). I can't create a PdfStamper from my PdfReader because I didn't provide the owner password to the reader. Is there any way to do this programmatically or must I recreate the document? Even using FdfReader requires a PdfStamper. Am I missing anything? Anything legal that is - I'm pretty sure I could hack the document, but I can't. Ironically, recreating it would probably be ok.
