You can't do this, as scrapy will not execute the JavaScript code. What you can do: Rely on a headless browser like Selenium, which will execute the JavaScript. Afterwards, use XPath (or simple DOM access) like before to query the web page after executing the page. Understand where the contents come from, and load and parse the source directly instead. Chrome Dev Tools / Firebug might help you with that, have a look at the "Network" panel that shows fetched data. Especially look for JSON, sometimes also XML.

I'm creating a unittest- and Selenium-based test suite for a web application. It is reachable by several hostnames, e.g. implying different languages; but of course I want to be able to test e.g. my development instances as well without changing the code (and without fiddling with the hosts file which doesn't work for me anymore, because of network security considerations, I suppose). Thus, I'd like to be able to specify the hostname by commandline arguments. The test runner does argument parsing itself, e.g. for chosing the tests to execute. What is the recommended method to handle this situation?

true

The solution I came up with finally is: Have a module for the tests which fixes the global data, including the hostname, and provides my TestCase class (I added an assertLoadsOk method to simply check for the HTTP status code). This module does commandline processing as well: It checks for its own options and removes them from the argument vector (sys.argv). When finding an "unknown" option, stop processing the options, and leave the rest to the testrunner. The commandline processing happens on import, before initializing my TestCase class. It works well for me ...

I'm trying to create a bot for an online game. The values for the game are stored in Javascript variables, which I can access. However, running my bot code in Javascript freezes the browser, since my code is the only thing that executes. I'm trying to code my bot in Python, then, since it can run synchronously with the browser. How can I pass the Javascript variables to a client-side Python program?

I'm trying to code my bot in Python, then, since it can run synchronously with the browser. How can I pass the JavaScript variables to a client-side Python program?... You can pass the JavaScript variables only with query string. I create the server in CherryPy (CherryPy is an object-oriented web application framework using the Python ) and the client function with file HTML. Repeat: The data can be passed only by query string because the Server works statically and the Client works dynamically. This is a stupid sentence but so function a general Client/Server. The server receive a call or message one times and offers the service and response. I also can wrong....This is a my opinion. Exists Mako Templates where you can include the pages HTML (helpful for build the structure of the site) or pass variable from Server to Client. I not know nothing programs or languages that you can pass the JavaScript variable to Server (and I try with Mako Templates but not function).

I created a simple threaded python server, and I have two parameters for format, one is JSON (return string data) and the other is zip. When a user selects the format=zip as one of the input parameters, I need the server to return a zip file back to the user. How should I return a file to a user on a do_GET() for my server? Do I just return the URL where the file can be downloaded or can I send the file back to the user directly? If option two is possible, how do I do this? Thank you

The issue was that I hadn't closed the zipfile object before I tried to return it. It appeared there was a lock on the file. To return a zip file from a simple http python server using GET, you need to do the following: Set the header to 'application/zip' self.send_header("Content-type:", "application/zip") Create the zip file using zipfile module Using the file path (ex: c:/temp/zipfile.zip) open the file using 'rb' method to read the binary information openObj = open( < path > , 'rb') return the object back to the browser openObj.close() del openObj self.wfile.write(openObj.read()) That's about it. Thank you all for your help.

Is there a way to send data packets from an active Python script to a webpage currently running JavaScript? The specific usage I'm looking for is to give the ability for the webpage, using JavaScript, to tell the Python script information about the current state of the webpage, then for the Python script to interpret that data and then send data back to the webpage, which the JavaScript then uses to decide which function to execute. This is for a video game bot (legally), so it would need to happen in real time. I'm fairly proficient in Python and web requests, but I'm just getting into JavaScript, so hopefully a solution for this wouldn't be too complex in terms of Javascript. EDIT: One way I was thinking to accomplish this would be to have Javascript write to a file that the Python script could also read and write to, but a quick google search says that JavaScript is very limited in terms of file I/O. Would there be a way to accomplish this?

I've written a script that pulls data from my school's website and I'm having some trouble with execution time. There are over 20 campuses, each with data for three semesters. The script looks up those school names, then the semesters available for each school, then the subjects/departments that are offering classes each semester. Then the script searches for the classes per department and then I do things with that data. I timed the execution of the script on just one campus, and it ran for over three minutes. When I ran it for all 24 campuses it took over an hour. I'm using the "requests" library, which runs each HTTP request in synchronously. I'm using the "requests" library, primarily because it handles sessions nicely. I'm looking for ways to bring down the time the script takes to run, by making the various requests for each semester run in parallel. I suspect that if I run three semesters asynchronously, then each school should take a minute, instead of three. Then, I can run all schools in parallel and achieve the same minute for all of the data. A minute is a lot less than an hour and a quarter! Am I wrong in my guess that multithreading/processing will bring down the execution time so drastically? What Python libraries should I be using for threads or processes? Once I've got each school being processed on a thread, how do I consolidate the data from all the schools into one place? I know that it's considered poor practice for threads to alter global state, but what's the alternative here?

I know the httpserver module in tornado is implemented based on the tcpserver module, so I can write a socket server based on tornado. But how can I write a server that is both a socket server and a web server? For example, if I want to implement a chat app. A user can either login through a browser or a client program. The browser user can send msg to the client user through the back-end server. So the back-end server is a web and socket server.

It may not be the fastest solution, but it is short and seems to work... clonedtag = BeautifulSoup(str(sourcetag)).body.contents[0] BeautifulSoup creates an extra <html><body>...</body></html> around the cloned tag (in order to make the "soup" a sane html document). .body.contents[0] removes those wrapping tags. This idea was derived Peter Woods comment above and Clemens Klein-Robbenhaar's comment below.

Use wireshark, you have to setup a filter for ftp (filter like: port ftp). Then start sniffing the transfer traffic. When the transfer is done you can see the captured packets in the main window. You have to right click on the first ftp packet and then select "Follow TCP stream". Then you should be able to view all your transfered bytes and such. This works also with tcpdump and such but it is commandline only. Kind regards, Dirk

I am using asynchronous socket API in C#. In the client side, I need a buffer to store the binary data read from the server.

When I make an HTTPS request using the aiohttp library with asyncio and Python 3.4 in Windows 7, the request fails with a NotImplementedError in the _make_ssl_transport function in base_events.py as shown in the traceback. On Windows, I use the ProactorEventLoop. I think you have to use that one to get asyncio to work. I tried the same request in a Debian 7 VM with a compiled version of Python 3.4, and the same request works. I don't use the ProactorEventLoop in Debian, just the default though. Any ideas or workarounds? Or, should I give up with aiohttp HTTPS on Windows for now? I am not able to use Linux for this project, needs to be on Windows.

Although it might be possible to use a single connection for multiple services, that's not how boto is written and as the comment above states, I doubt very much that it would improve your performance. I would recommend that you create a single connection per service and keep reusing that connection. Boto caches connections and will also handle any reconnection that might be required if you don't use the connection for a while or encounter some error.

I have a couple of gigantic XML files (10GB-40GB) that have a very simple structure: just a single root node containing multiple row nodes. I'm trying to parse them using SAX in Python, but the extra processing I have to do for each row means that the 40GB file takes an entire day to complete. To speed things up, I'd like to use all my cores simultaneously. Unfortunately, it seems that the SAX parser can't deal with "malformed" chunks of XML, which is what you get when you seek to an arbitrary line in the file and try parsing from there. Since the SAX parser can accept a stream, I think I need to divide my XML file into eight different streams, each containing [number of rows]/8 rows and padded with fake opening and closing tags. How would I go about doing this? Or — is there a better solution that I might be missing? Thank you!

You can't easily split the SAX parsing into multiple threads, and you don't need to: if you just run the parse without any other processing, it should run in 20 minutes or so. Focus on the processing you do to the data in your ContentHandler.

I am running selenium webdriver (firefox) using python on a headless server. I am using pyvirtualdisplay to start and stop the Xvnc display to grab the image of the sites I am visiting. This is working great except flash content is not loading on the pages (I can tell because I am taking screenshots of the pages and I just see empty space where flash content should be on the screenshots). When I run the same program on my local unix machine, the flash content loads just fine. I have installed flash on my server, and have libflashplayer.so in /usr/lib/mozilla/plugins. The only difference seems to be that I am using the Xvnc display on the server (unless plash wasn't installed properly? but I believe it was since I used to get a message asking me to install flash when I viewed a site that had flash content but since installing flash I dont get that message anymore).

However, I've realized that the tests I have won't work the way I want them to if it's close to midnight, as the times I'm passing in will wrap to the next day, and be earlier than the current time rather than later, or vice versa. Is it possible to run these tests as if it were a specific date/time?

false

If you want to keep the date/time constant for the purpose of your tests, you can just hardcode the date/time and passing it to the methods you want to test. If "hardcoding a date" doesn't feel right you could hardcode the specific sequence of actions that a browser might go through, to pick a particular date that happens to be static. After all, you are testing whether your method correctly determines whether a date is before or after another date; how the input is provided is not relevant.

I'm not aware of any way to see that via the API. That's typically something you'd leave up to the end-user to know when they're signing up. Ask them if they have Pro or not, and based on that, setup your permissions request accordingly.

I am trying to write my own proxy extensions. Both, burp suite as well as mitmproxy allows us to write extensions. Till now, I am successful with intercepting the request and response headers, and write it to my own output file. The problem is, I get frequent requests and responses at anonymous time and at the same time, the output is getting written in the file. How should I identify that which response belongs to which particular request ?? If we see in burp suite, when we click on particulat URL in target, we see two different tabs- "Request" and "Response". How is burp suite identifying this ? Similar is the case with mitmproxy. I am new to proxy extensions, so any help would be great. ----EDIT---- If any additional information is required then pls let me know.

I have a directory of images that I'd like to transfer to Google drive via a python script. What's a good way to upload (recursively) a directory of images to Google drive while preserving the original directory structure? Would there be any benefit to making this multithreaded? And if so, how would that work?

I would do this in two passes. Start by scanning the folder hierarchy, and then recreate the folders on drive. Update your in-memory folder model with the Drive folder ids. Then scan your files, uploading each one with appropriate parent id. Only make it multithreaded if each thread will have a unique client id. Otherwise you will end up triggering the rate limit bug in Drive. If you have a large number of files, buy the boxed set of Game Of Thrones.

I need to calculate a digest (checksum) from the request body (e.g. raw POST data) that is being sent via QNetworkRequest and include a digest signature in the request header. How could I do this before sending the request (so the signature can be included in the header) ? This is trivial when I'm using a byte array as the request body, but what if I have a QHttpMultiPart object ? Basically something like QHttpMultiPart.toString().

I would like to start the conversation in blocking mode and later switch to non-blocking. Is that a stupid idea? The python docs are kind of ambiguous about it, there it says: ... You do this [setblocking(0)] after creating the socket, but before using it. (Actually, if you’re nuts, you can switch back and forth.) I read this as 'please don't do that', so I was wondering if there are reasons as to why it is discouraged. Is there some kind of undefined behavior, what problems could I run into?

Yes you can do this, but mostly people do multiple blocking sockets with threads or multiple non-blocking sockets with event loops. But it should be no problem in switching in-between, as long as you don't switch between buffered and unbuffered I/O.

I'm using Selenium (python bindings, with Django) for automated web app testing. My page has a form with a button, and the button has a .click() handler that captures the click (i.e. the form is not immediately submitted). The handler runs function2(), and when function2() is done, it submits the form. In my test with Selenium, I fill in the form, then click the Submit button. I want to verify that the form is eventually submitted (resulting in a POST request). The form POSTs and then redirects with GET to the same url, so I can't check for a new url. I think I need to check that the POST request occurs. How do I check for successful form submission? Alternatively I could check at the database level to see that some new object is created, but that would make for a bad "unit" test.

false

23,397,090

I guess it depends on how deep down the rabbit hole you want to go. If you're building a test for the functional side from the user's perspective, and your GET action results in changes on the webpage, then trigger the submit with selenium, then wait for the changes to propagate to the webpage (like waiting for one/more elements to change value or waiting for an element to appear) If you want to build an unit test, then all you should be testing is the ability to Submit the data, not also the ability of the javascript code to do a POST request, then a GET then display the data. If you want to build an integration test, then you will need to check that each individual action in the sequence you described is performed correctly in whatever scenario you deem appropriate and then check that the total result of those actions is as expected. The tricky part will be chaining all those checks together. If you want to build an end to end test, then you need to check for all of the above, plus changes to any permanent storage locations that the code you test changes (like databases or in-memory structures) plus whatever stress/security/usability/performance checks your software needs to pass in your specific context.

I am using scrapy to scrape reviews about books from a site. Till now i have made a crawler and scraped comments of a single book by giving its url as starting url by myself and i even had to give tags of comments about that book by myself after finding it from page's source code. Ant it worked. But the problem is that till now the work i've done manually i want it to be done automatically. i.e. I want some way that crawler should be able to find book's page in the website and scrape its comments. I am extracting comments from goodreads and it doesn't provide a uniform method for url's or even tags are also different for different books. Plus i don't want to use Api. I want to do all work by myself. Any help would be appreciated.

Is there a way to get CherryPy to respond to a url that includes a period, such as http://some/base/path/oldscript.py ? I have a number of old CGI scripts that were called like that, and I'm trying to roll them into a nice pretty CherryPy web app - but I don't want to break all the bookmarks and the like that still point to the CGI scripts. Ideally the same method would respond to the url regardless of if it has a .py or not.

Turns out using an _ in the method definition works as a dot/period. This does mean I have to have two function definitions if I want to be able to call it either with or without the .py, but since I can easily call the one function from the other, this is a minor quibble.

I have built a program for summarization that utilizes a parser to parse from multiple websites at a time. I extract only <p> in each article.

Your solution is really going to be specific to each website page you want to scrape, so, without knowing the websites of interest, the only thing I could really suggest would be to inspect the page source of each page you want to scrape and look if the article is contained in some html element with a specific attribute (either a unique class, id, or even summary attribute) and then use beautiful soup to get the inner html text from that element

I'm working on a game that allows you to add other users as your friend. The game is in Flash AS2 and the server is Python. I'm currently hoping to make it so the game sends an HTTP request to an API server that will then verify everything, such as if they're already friends, if they can be friends, etc, and then if everything's okay, I'd then insert the request into a request able. Anyway, if the user is currently online, I would like to send the user a notification through the server. The only way I could see this happening is if I opened up a socket connection through the add friend script and then sent a special packet letting the server know that it needs to send the notification. Right now that seems like it would take a while to do and not so efficient if a lot of users used it daily. How would I best approach this and is there any other efficient ways?

true

23,507,196

0

I've decided it would be better if I still do the HTTP request, but depending on what the request returned, I could have the client send a packet to the server telling it to give the specific user a notification. For example, if I tried adding user ID #323095643, I send the HTTP request and everything turns out okay and I get an OK response, the flash client sends a packet to the server basically saying "Hey, give user ID #323095643 a notification saying '_ wants you to be their friend'" and it sends it to that user.

Basically I need a tool (preferably for linux) for getting some data from webpage, opening some others, filling form on them, closing windows and clicking on some buttons. What would be the tool for doing this in whole? Some scripting language like Perl or Python can do it for me? This is maybe difficult so give me the way that is most user friendly. :-) I am not familiar with Perl or Python, but I am strong in my will to make it work because it is important to me. Notify that I can't do anything on the server, so everything that needs to be done is from clientside/web browser. open webpage on that page click on the link to open webpage in new window on new page click on two radio buttons and submit close that window and return to previous extract part of the text from tag that follows text "IP Address: " to the end of the line and save it to the variable extract part of the text from tag that follows text "Timestamp: " to the end of the line and save it to the variable extract part of the text from tag that follows text "File Name: " to the end of the line and save it to the variable (these three are similar to make) open URL in the new window fill in the form with the data that is extracted from the previous page and submit if there is "answer"(result is table) from the form do "procedure1"(copy entire table with result and concat its cells, close window and return to previous, again click some buttons/links on that page etc.....) if there is "no answer"(empty table) from the form do "precedure2"(opening new window, filling form with data in variables, clicking some buttons and closing that window) than proceed to "procedure1" Thank you all for helping me.

I am trying to use Python Selenium to click a button on a webpage, but Selenium is giving exception "Element is not currently visible and so may not be interacted with". The DOM structure is quite simple: <body style="overflow: hidden;"> ... <div aria-hidden="false" style="display: block; ..."> ... <button id="button-aaa" aria-hidden="true" style="..."> ... </div> ... </body> I have searched Google and Stackoverflow. Some users say Selenium cannot click a web element which is under a parent node with overflow: hidden. But surprisingly, I found that Selenium is able to click some other buttons which are also under a parent node with overflow: hidden. Anyway, I have tried to use driver.execute_script to change the <body> style to overflow: none, but Selenium is still unable to click this button. I have also tried to change the button's aria-hidden="true" to aria-hidden="false", but Selenium still failed to click. I have also tried to add "display: block;" to the button's style, and tried all different combination of style changes, but Selenium still failed to click. I have used this commands to check the button: buttonelement.is_displayed(). It always returns False no matter what style I change in the DOM. The button is clearly visually visible in the Firefox browser, and it is clickable and functioning. By using the Chrome console, I am able to select the button using ID. May I know how can I check what is causing a web element to be invisible to Python Selenium?

I'm working on a project that needs to parse a very big XML file (about 10GB). Because process time is really long (about days), It's possible that my code exit in the middle of the process; so I want to save my code's status once in a while and then be able to restart it from last save point. Is there a way to start (restart) a SAX parser not from the beginning of a XML file? P.S: I'm programming using Python, but solutions for Java and C++ are also acceptable.

Not really sure if this answers your question, but I would take a different approach. 10GB is not THAT much data, so you could implement a two-phase parsing. Phase 1 would be to split the file in smaller chunks based on some tag, so you end up with more smaller files. For example if your first file is A.xml, you split it to A_0.xml, A_1.xml etc. Phase 2 would do the real heavy lifting on each chuck, so you invoke it on A_0.xml, then after that on A_1.xml etc. You could then restart on a chunk after your code has exitted.

Start simple and use the way, which seems to be easy to use for you. Consider optimization to be done later on only if needed. Use of async libraries would come into play as helpful if you would have thousands of request a second. Much sooner you are likely to have performance problems related to database (if you use it), which is not to be resolved by async magic.

This problem is a bit underspecified. Say, you're on some Windows: You could assign the correct python invocation as default open action to the .xml file type, but this would then apply to all .xml files. And you might need elevated access rights to perform the change. On Linux, you'd have to deal with various ways of desktop environments ... and then I'd open an issue because it does not work with xfe running under awesome on my box here. In short: Solve this problem by avoiding it. Can you make do with "drag this file onto the application icon"? Can you make the .xml files appear in a dedicated place and have a background task check for new ones?

I'd like to know if is it possible to browse all links in a site (including the parent links and sublinks) using python selenium (example: yahoo.com), fetch all links in the homepage, open each one of them open all the links in the sublinks to three four levels. I'm using selenium on python. Thanks Ala'a

Sure it is possible, but you have to instruct selenium to enter these links one by one as you are working within one browser. In case, the pages are not having the links rendered by JavaScript in the browser, it would be much more efficient to fetch these pages by direct http request and process it this way. In this case I would recommend using requests. However, even with requests it is up to your code to locate all urls in the page and follow up with fetching those pages. There might be also other Python packages, which are specialized on this kind of task, but here I cannot serve with real experience.

I am writing a socket based "python cmd like" server module which can support cli interactive functions such as autocompletion or command history, by doing that a simple "telnet" or "nc" client side may able to connect to server to read/set something on server side. after searching, there are a lot of modules can do "cmd" part such like python standard module "cmd" or "ipython" or even vty simulator, however, I cannot find a module can actually bind to socket directly to detect keystrokes such as "tab" key or "control+c" client side. Most of them just able to process line(s) read, which not suitable for autocompletion with tab press or command history with up/down press. I think this question can be simplify to: Is that possible to read socket keystroke input non-blocking, then process this key input value somehow server side - for example ASCII code + 1, then echo back to socket to show in client side? Thank you for your help.

What you want is not possible. As you say, you want to write a socket based cmd like server. The server will open a socket and listen for data from the client. Now it is possible to read socket input character by character (which is not the same as non-blocking BTW), but that will not help you. It is up to the client program to decide how and when to send the data. So if the client side program decides to "eat" tab and control characters, then you will simply not see them. So if you want to process keystrokes one by one, you will also need a client application.

This is my first StackOverflow post so please bear with me. What I'm trying to accomplish is a simple program written in python which will change all of a certain html tag's content (ex. all <h1> or all <p> tags) to something else. This should be done on an existing web page which is currently open in a web browser. In other words, I want to be able to automate the inspect element function in a browser which will then let me change elements however I wish. I know these changes will just be on my side, but that will serve my larger purpose. I looked at Beautiful Soup and couldn't find anything in the documentation which will let me change the website as seen in a browser. If someone could point me in the right direction, I would be greatly appreciative!

What you are talking about seems to be much more of the job of a browser extension. Javascript will be much more appropriate, as @brbcoding said. Beautiful Soup is for scraping web pages, not for modifying them on the client side in a browser. To be honest, I don't think you can use Python for that.

I'm trying to teach myself a concept by writing a script. Basically, I'm trying to write a Python script that, given a few keywords, will crawl web pages until it finds the data I need. For example, say I want to find a list of venemous snakes that live in the US. I might run my script with the keywords list,venemous,snakes,US, and I want to be able to trust with at least 80% certainty that it will return a list of snakes in the US. I already know how to implement the web spider part, I just want to learn how I can determine a web page's relevancy without knowing a single thing about the page's structure. I have researched web scraping techniques but they all seem to assume knowledge of the page's html tag structure. Is there a certain algorithm out there that would allow me to pull data from the page and determine its relevancy? Any pointers would be greatly appreciated. I am using Python with urllib and BeautifulSoup.

You're basically asking "how do I write a search engine." This is... not trivial. The right way to do this is to just use Google's (or Bing's, or Yahoo!'s, or...) search API and show the top n results. But if you're just working on a personal project to teach yourself some concepts (not sure which ones those would be exactly though), then here are a few suggestions: search the text content of the appropriate tags (<p>, <div>, and so forth) for relevant keywords (duh) use the relevant keywords to check for the presence of tags that might contain what you're looking for. For example, if you're looking for a list of things, then a page containing <ul> or <ol> or even <table> might be a good candidate build a synonym dictionary and search each page for synonyms of your keywords too. Limiting yourself to "US" might mean an artificially low ranking for a page containing just "America" keep a list of words which are not in your set of keywords and give a higher ranking to pages which contain the most of them. These pages are (arguably) more likely to contain the answer you're looking for good luck (you'll need it)!

I've created a test that click on an element X. This element is only revealed after you click on another button, and those elements are connected with ng-hide. When i try to run my code the click on X element doesn't work. However, in debug mode or after adding 1 second sleep, it does. I'm using selenium framework in python, with a remote webdriver with ImplicitlyWait of 10 sec. Does someone knows the reason for this behavior?

false

As said by @Siking, this is clearly a timing issue. The fact is that Selenium is very fast and faster than loading of element. Sometimes, Selenium requires a pause or a sleep to ensure that an element is present. I also recommend -especially for asynchronous requests- using waitForElementPresent to wait until ajax method is finished.

I need to transfer data via pyzmq through two computers connected by an ethernet cable. I have already set up a script that runs on the same computer correctly, but I need to find the tcp address of the other computer in order to communicate. They both run Ubuntu 14.04. One of them should be a server processing requests while the other sends requests. How do I transfer data over tcp through ethernet? I simply need a way to find the address. EDIT: (Clarification) I am running a behavioural study. I have a program called OpenSesame which runs in python and takes python scripts. I need a participant to be able to sit at a computer and be able to ask another person questions (specifically for help in a task).

Maybe you could periodically send datagram message containing peer's ip address (or some other useful information) to broadcast address, to allow other peers to discover it. And after peer's address is dicovered you can estabish connection via ZeroMQ or other kind... connection. :)

My script logs in to my account, navigates the links it needs to, but I need to download an image. This seems to be easy enough to do using urlretrive. The problem is that the src attribute for the image contains a link which points it to the page which initiates a download prompt, and so my only foreseeable option is to right click and select 'save as'. I'm using mechanize and from what I can tell Mechanize doesn't have this functionality. My question is should I switch to something like Selenium?

The Freebase dump is in RDF format. The easiest way to query it is to dump it (or a subset of it) into an RDF store. It'll be quicker to query, but you'll need to pay the database load time up front first.

There are 2 possible ways: 1) UPnP / NATPMP / PCP - These are protocols implemented by some(most?) routers more likely local networks to allow applications behind a firewall interact in this case you send packets (from both clients) to their respective routers using the protocol mentioned above asking for a port opening, then communicate regulary using sockets. 2) In some cases NAT traversal is possible - read about STUN servers and the ICE protocol. - This is most common for UDP communication, though sometimes TCP traffic can be also traversed in the network this way - most common tech is UDP hole punching 3) If none of these apply (say, symmetric NAT on a huge scale network) the only way would be a TURN approach when you relay all data through your publicly accesible server. P2P and NAT traversal are common in SIP,Voip and torrents, hence, free libraries like VUZE (torrent open source lib) can be a good place to start digging... :)

I need to create a BASH script, ideally using SED to find and replace value lists in href URL link constructs with HTML sit files, looking-up in a map (old to new values), that have a given URL construct. There are around 25K site files to look through, and the map has around 6,000 entries that I have to search through. All old and new values have 6 digits. The URL construct is: One value: HREF=".*jsp\?.*N=[0-9]{1,}.*" List of values: HREF=".*\.jsp\?.*N=[0-9]{1,}+N=[0-9]{1,}+N=[0-9]{1,}...*" The list of values are delimited by + PLUS symbol, and the list can be 1 to n values in length. I want to ignore a construct such as this: HREF=".*\.jsp\?.*N=0.*" IE the list is only N=0 Effectively I'm only interested in URL's that include one or more values that are in the file map, that are not prepended with CHANGED -- IE the list requires updating. PLEASE NOTE: in the above construct examples: .* means any character that isn't a digit; I'm just interested in any 6 digit values in the list of values after N=; so I've trying to isolate the N= list from the rest of the URL construct, and it should be noted that this N= list can appear anywhere within this URL construct. Initially, I want to create a script that will create a report of all links that fulfills the above criteria and that have a 6 digital OLD value that's in the map file, with its file path, to get an understanding of links impacted. EG: Filename link filea.jsp /jsp/search/results.jsp?N=204200+731&Ntx=mode+matchallpartial&Ntk=gensearch&Ntt= filea.jsp /jsp/search/BROWSE.jsp?Ntx=mode+matchallpartial&N=213890+217867+731& fileb.jsp /jsp/search/results.jsp?N=0+450+207827+213767&Ntx=mode+matchallpartial&Ntk=gensearch&Ntt= Lastly, I'd like to find and replace all 6 digit numbers, within the URL construct lists, as outlined above, as efficiently as possible (I'd like it to be reasonably fast as there could be around 25K files, with 6K values to look up, with potentially multiple values in the list). **PLEASE NOTE:** There is an additional issue I have, when finding and replacing, is that an old value could have been assigned a new value, that's already been used, that may also have to be replaced. E.G. If the map file is as below: MAP-FILE.txt OLD NEW 214865 218494 214866 217854 214867 214868 214868 218633 ... ... and there is a HREF link such as: /jsp/search/results.jsp?Ntx=mode+matchallpartial&Ntk=gensearch&N=0+450+214867+214868 214867 changes to 214868 - this would need to be prepended to flag that this value has been changed, and should not be replaced, otherwise what was 214867 would become 218633 as all 214868 would be changed to 218633. Hope this makes sense - I would then need to run through file and remove all 6 digit numbers that had been marked with the prepended flag, such that link would become: /jsp/search/results.jsp?Ntx=mode+matchallpartial&Ntk=gensearch&N=0+450+214868CHANGED+218633CHANGED Unless there's a better way to manage these infile changes. Could someone please help me on this, I'm note an expert with these kind of changes - so help would be massively appreciated. Many thanks in advance, Alex

I will write the outline for the code in some kind of pseudocode. And I don't remember Python well to quickly write the code in Python. First find what type it is (if contains N=0 then type 3, if contains "+" then type 2, else type 1) and get a list of strings containing "N=..." by exploding (name of PHP function) by "+" sign. The first loop is on links. The second loop is for each N= number. The third loop looks in map file and finds the replacing value. Load the data of the map file to a variable before all the loops. File reading is the slowest operation you have in programming. You replace the value in the third loop, then implode (PHP function) the list of new strings to a new link when returning to a first loop. Probably you have several files with the links then you need another loop for the files. When dealing with repeated codes you nees a while loop until spare number found. And you need to save the numbers that are already used in a list.

The scenario: I have a Networkx network with around 120.000 edges which I need to query each time a user requests a page or clicks something on the page, so a lot of calls. I could load and parse the network each call, but that would be a waste of time as that would take around 4 seconds each time (excluding the querying). I was hoping I could store this network object (which is static) somewhere globally and just query it when needed, but I can't find an easy way to do so. Putting all the edges in a DB is not an option as it doesn't eliminate the time needed for parsing.

You could simply install it as a global variable. Call the function that loads it in a module-level context and import that module when you need it (or use a singleton pattern that loads it on first access, but it's basically the same thing). You should never use a global variable in a webapp if you expect to alter the contents on the fly, but for static content there's nothing wrong with them. Just be aware that if you put the import inside a function, then that import will run for the first time when that function is run, which means that the first time someone accesses a specific server after reboot they'll have to wait for the data to load. If you instead put the import in a module-level context so that it's loaded on app start, then your app will take four seconds (or whatever) longer to start in the first place. You'll have to pick one of those two performance hits -- the latter is probably kinder to users.

I am trying to run a python script in which I am opening a webpage and clicking on some element. But the script is running very slow and giving random exceptions . Mostly it halts at line driver = webdriver.Firefox() Message - selenium.common.exceptions.WebDriverException: Message: 'Can\'t load the profile. Profile ?Dir: /tmp/tmp4liaEq Firefox output: Xlib: extension "RANDR" missing on display ":1733".\n1403086712970\taddons.xpi\tDEBUG\tstartup\n1403086713204\taddons.xpi\tDEBUG\tcheckForChanges\n1403086713568\taddons.xpi\tDEBUG\tNo changes found\n' Sometimes - driver.find_element_by_xpath("//a[@id='some_id']") Returning error that the element is not visible so can't be clicked. The same script runs smoothly on my system that has 4GB RAM.

Even JavaScript is using http requests to get the data, so one method would be to investigate, what requests are providing the data when user asks to "Load more results" and emulate these requests. This is not traditional scraping, which is based on plain or rendered html content and detecting further links, but can be working solution. Next actions: visit the page in Google Chrome or Firefox press F12 to start up Developer tools or Firebug switch to "Network" tab click "Load more results" check, what http requests have served data for loading more results and what data they return. try to emulate these requests from Python Note, that the data do not necessarily come in HTML or XML form, but could be in JSON. But Python provide enough tools to process this format too.

I'd like to write a program that parses an online .docx file to build an XML document. I know (or at least I think I know) that browsers need a plug-in to view .docx in browser, but I'm not that familiar with plug-ins or how the work. After looking at a .docx file in Notepad++, it seems clear to me that I won't be able to parse the binary data. Is there a way to simulate the opening of the .docx file for my purposes (EDIT: that is, without downloading and saving the file to my hard drive) within the the abilities of any languages or libraries? My question is more about the opening of the file without downloading than about the actual parsing of it, as I've looked into the Apache POI API for parsing the document in Java.

Let me try to make this clear. If you are viewing it, then you have downloaded it. You are "downloading" this webpage in order for your browser to render it. You're "downloading" a link to a document which tells you that there is a document. You cannot view the document unless you download it. Yes, you have to download it. Downloading a file is just getting it from the remote server. Of course, you don't have to write it to your hard drive. You can download it and store it in memory, and then deal with it from memory. Once you open a connection, you get an InputStream object to read bytes. You can pass that into the Apache POI libraries to read the file.

I been using python to create an web app and it has been doing well so far. Now I would like to encrypt the transmission of the data between client and server using https. The communication is generally just post form and web pages, no money transactions are involve. Is there anything I need to change to the python code except setting the server up with certificate and configurate it to use https? I see a lot of information regarding ssl for python and I not sure if I need those modules and python setup to make https work. Thanks

Typically, the ssl part for Python web app is managed by some frontend web server like nginx, apache or so. This does not require any modification of your code (assuming, you are not expecting user to authenticate by ssl certificate on client side, what is quite exotic, but possible scenario). If you want to run pure Python solution, I would recommend using cherrypy, which is able providing rather reliable and performant web server part (it will be very likely slower then served behind nginx or apache).

How can I programmatically convert urllib2.Request object into the equivalent curl command? My Python script constructs several urllib2.Request objects, with different headers and postdata. For debugging purposes, I'd like to replay each request with curl. This seems tricky, as we must consider Bash escaping and urllib2's default headers. Is there a simple way to do this?

false

Simple way would be to run wireshark to capture the desired requests and then replay them with a packet replay tool like TCPreplay. If you do want to modify parts in curl for debugging wireshark will show you all the headers urllib2 is setting so you can set them the same in curl.

Netsuite has provided toolkits for Java, .Net and PHP to access their webservices. For other languages either there are third party toolkits or you have to send Raw SOAP requests. For my Python based projects I'm using Raw SOAP requests method. I suggest that first you get familiar with Netsuite Web services using any of the available toolkits and then for Python use this knowledge to generate raw SOAP requests. SOAPUI can also be of great help. Have you explored restlets they are a generally good alternate for webservices.

I'm working on an online multiplayer game. I already developed the login servers and database for any persistent storage; both are written in Python and will be hosted with Google's App Engine. (For now.) I'm relatively comfortable with two languages - Java and Python. I'd like to write the actual gameplay server in one of those languages, and I'd like for the latency of the client to gameplay-server connection to be as low as possible, so I assume that the majority of gameplay data (e.g. fine player movements) will need to be sent via UDP connections. I'm unfamiliar with UDP connections so I really don't know where to begin designing the server. How should the server be threaded? One thread per client connection that retains session info, and then a separate thread(s) to control autonomous world changes (NPCs moving, etc.)? How should relatively large packets be transmitted? (e.g. ~25 nearby players and all of their gameplay data, usernames, etc.) TCP or UDP? Lastly - is it safe for the gameplay server to interface with the login server via HTTP requests, how do I verify (from the login server's perspective) the gameplay server's identity - simple password, encryption? Didn't want to ask this kind of question because I know they're usually flagged as unproductive - which language would be better for me (as someone inexperienced with socketing) to write a sufficiently efficient server - assume equal experience with both? Lastly - if this is relevant - I have not begun development on the client - not sure what my goals for the game itself are yet, I just want the servers to be scalable (up to ~150 players, beyond that I expect and understand that major rewrite will probably be necessary) and able to support a fair amount of players and open-world style content. (no server-taxing physics or anything like that necessary)

"I assume that the majority of gameplay data (e.g. fine player movements) will need to be sent via UDP connections. I'm unfamiliar with UDP connections so I really don't know where to begin designing the server." UDP can be lower latency, but sometimes, it is far more important that packets aren't dropped in a game. If it makes any difference to you, World of Warcraft uses TCP. If you chose to use UDP, you would have to implement something to handle dropped packets. Otherwise, what happens if a player uses an important ability (Such as a spell interrupt or a heal) and the packet gets dropped? You COULD use both UDP and TCP to communicate different things, but that adds a lot of complexity. WoW uses only a single port for all gameplay traffic, plus a UDP port for the in-game voice chat that nobody actually uses. "How should the server be threaded? One thread per client connection that retains session info, and then a separate thread(s) to control autonomous world changes (NPCs moving, etc.)?" One thread per client connection can end up with a lot of threads, but would be a necessity if you use synchronous sockets. I'm not really sure of the best answer for this. "How should relatively large packets be transmitted? (e.g. ~25 nearby players and all of their gameplay data, usernames, etc.) TCP or UDP?" This is what makes MMORPG servers so CPU and bandwidth intense. Every action has to be relayed to potentially dozens of players, possibly hundreds if it scales that much. This is more of a scaling issue than a TCP vs UDP issue. To be honest, I wouldn't worry much about it unless your game catches on and it actually becomes an issue. "Lastly - is it safe for the gameplay server to interface with the login server via HTTP requests, how do I verify (from the login server's perspective) the gameplay server's identity - simple password, encryption?" You could easily use SSL. "Lastly - if this is relevant - I have not begun development on the client - not sure what my goals for the game itself are yet, I just want the servers to be scalable (up to ~150 players, beyond that I expect and understand that major rewrite will probably be necessary) and able to support a fair amount of players and open-world style content. (no server-taxing physics or anything like that necessary)" I wouldn't use Python for your server. It is horrendously slow and won't scale well. It's fine for web servers and applications where latency isn't too much of an issue, but for a real-time game server handling 100+ players, I'd imagine it would fall apart. Java will work, but even THAT will run into scaling issues before a natively coded server does. I'd use Java to rapidly prototype the game and get it working, then consider a rewrite in C/C++ to speed it up later. Also, something to consider regarding Python...if you haven't read about the Global Interpreter Lock, I'd make sure to do that. Because of the GIL, Python can be very ineffective at multithreading unless you're making calls to native libraries. You can get around it with multiprocessing, but then you have to deal with the overhead of communication between processes.

I want to be able to edit existing XML config files via Python while preserving the formatting of the file and the comments in them so that its still human readable. I will be updating existing XML elements and changing values as well as adding new XML elements to the file. Available XML parsers such as ElementTree and lxml are great ways to edit XML files but you loose the original formatting(when adding new elements to the file) and comments that were in the file. Using Regular expressions seems to be an option but I know that this is not recommended with XML. So I'm looking for something along the lines of a Pythonic XML file editor. What is the best way to go about this? Thanks.

Similar for the client. It's not the ideal solution and I'd be thankful if someone comes up with a better one but that is how I use it now.

Both "localhost" and "127.0.0.1" are local loopback interfaces only: they only make sense within the same machine. From your Android device, assuming it's on the same wifi network as your machine, you'll need to use the actual IP address of your main machine: you can either find that from the network settings of that machine, or from your router's web interface.

I'm analyzing tweets and need to find which state (in the USA) the user was in from their GPS coordinates. I will not have an internet connection available so I can't use an online service such as the Google Maps API to reverse geocode. Does anyone have any suggestions? I am writing the script in python so if anyone knows of a python library that I can use that would be great. Or if anyone can point me to a research paper or efficient algorithm I can implement to accomplish this that would also be very helpful. I have found some data that represents the state boundaries in GPS coordinates but I can't think of an efficient way to determine which state the user's coordinates are in.

Use a point-in-polygon algorithm to determine if the coordinate is inside of a state (represented by a polygon with GAP coordinates as points). Practically speaking, it doesn't seem like you would be able to improve much upon simply checking each state one at a time, though some optimizations can be made if it's too slow. However, parts of Alaska are on both sides of the 180th meridian which cases problems. One solution would be to offset the coordinates a bit by adding 30 degrees modulus 180 to the longitude for each GPS coordinate (user coordinates and state coordinates). This has the effect of moving the 180th meridian about 30 degrees west and should be enough to ensure that the entire US on one side of the 180th meridian.

If you want the latest tweets from specific users, Twitter offers the Streaming API. The Streaming API is the real-time sample of the Twitter Firehose. This API is for those developers with data intensive needs. If you're looking to build a data mining product or are interested in analytics research, the Streaming API is most suited for such things. If you're trying to access old information, the REST API with its severe request limits is the only way to go.

I'd like to detect if the browser made a request via AJAX (AngularJS) so that I can return a JSON array, or if I have to render the template. How can I do this?

There isn't any way to be certain whether a request is made by ajax. What I found that worked for me, was to simply include a get parameter for xhr requests and simply omit the parameter on non-xhr requests. For example: XHR Request: example.com/search?q=Boots&api=1 Other Requests: example.com/search?q=Boots

The simplest would be to use traffic shaping tools under linux, like tc. These tools let you control bandwidth and even simulate network packet loss or even long distance communication issues. Easy to write a python script to control the port behavior via a shell.
