When binding to a socket in python the value for host can be '' which means all interfaces. Or it can be a string containing a real ip address eg '192.168.1.5'. So its possible to bind to all or 1 interface. What if I have 3 interfaces and I want to bind to only 2 of them. Is this possible? What value do I give host, I have tired a list, a tuple, a comma separated string.

true

Unfortunately, it's not possible to bind to the subset of interfaces using socket module. This module provides access to BSD socket interface, which allow to specify only single address while binding. For this single address a special value of INADDR_ANY in C exists to allow for binding to all interfaces (Python translates empty string to this value). If you want to bind to more than one, but not all, interfaces using socket module, you'll need to create multiple sockets.

After completing the oAuth handshake with Intuit Anywhere (AI), I use the API to get the HTML for the blue dot menu. Sometimes, the expected HTML is returned. Other times, I get this message This API requires Authorization. 22 2013-01-10T15:32:33.43741Z Typically, this message is returned when the oAuth token is expired. However, on the occasions when I get it, I can click around in my website for a bit or do a refresh, and the expected HTML is returned. I checked the headers being sent and, in both cases (i.e., when the expected HTML is returned, and an error is returned), the request is exactly the same. I wouldn't be surprised if this was a bug in Intuit's API, but I'm trying to rule out any other possibilities first. Please let me know if you have any thoughts on how to fix this. Thanks. Update: It seems the problem is occurring only when I do a refresh. This seems to be the case both in Firefox and Safari on OSX. It sounds to be like a Javascript caching issue.

I received this error as well and am posting this as pointer for other who stumble upon this. Error Code 22 (Authentication required) for me meant that the OAuth signature was wrong. This was confusing because I couldn't find this error listed in the Quickbooks documents for reconnect. I was signing the request as a "POST" request instead of a "GET" request which is what Quickbooks requires for calls to the reconnect endpoint.

I have a server, onto which I want to use Python, that is behind a company firewall. I do not want to mess with it and the only thing I can do is to make a firewall exception for specific URL/domains. I also want to access packages located on PYPI, using pip or easy_install. Therefore, do you know which URL should I ask to be listed in the exception rules for the firewall, except *.pypi.python.org?

You need to open up your firewall to the download locations of any package you need to install, or connect to a proxy server that has been given access. Note that the download location is not necessarily on PyPI. The Python package index is a metadata service, one that happens to also provide storage for the indexed packages. As such, not all packages indexed on PyPI are actually downloaded from PyPI, the download location could be anywhere on the internet. I'd say you start with opening pypi.python.org, then as individual package installions fail, check their PyPI page and add the download location listed for those.

I'm new to python so please excuse me if question doesn't make sense in advance. We have a python messaging server which has one file server.py with main function in it. It also has a class "*server" and main defines a global instance of this class, "the_server". All other functions in same file or diff modules (in same dir) import this instance as "from main import the_server". Now, my job is to devise a mechanism which allows us to get latest message status (number of messages etc.) from the aforementioned messaging server. This is the dir structure: src/ -> all .py files only one file has main In the same directory I created another status server with main function listening for connections on a different port and I'm hoping that every time a client asks me for message status I can invoke function(s) on my messaging server which returns the expected numbers. How can I import the global instance, "the_server" in my status server or rather is it the right way to go?

Unless your "status server" and "real server" are running in the same process (that is, loosely, one of them imports the other and starts it), just from main import the_server in your status server isn't going to help. That will just give you a new, completely independent instance of the_server that isn't doing anything, which you can then report status on. There are a few obvious ways to solve the problem. Merge the status server into the real server completely, by expanding the existing protocol to handle status-related requests, as Peter Wooster suggestions. Merge the status server into the real server async I/O implementation, but still listening on two different ports, with different protocol handlers for each. Merge the status server into the real server process, but with a separate async I/O implementation. Store the status information in, e.g., a mmap or a multiprocessing.Array instead of directly in the Server object, so the status server can open the same mmap/etc. and read from it. (You might be able to put the Server object itself in shared memory, but I wouldn't recommend this even if you could make it work.) I could make these more concrete if you explained how you're dealing with async I/O in the server today. Select (or poll/kqueue/epoll) loop? Thread per connection? Magical greenlets? Non-magical cooperative threading (like PEP 3156/tulip)? Even just "All I know is that we're using twisted/tornado/gevent/etc., so whatever that does" is enough.

You should probably use a single server and design a protocol that supports several kinds of messages. 'send' messages get sent, 'recv' message read any existing message, 'status' messages get the server status, 'stop' messages shut it down, etc. You might look at existing protocols such as REST, for ideas.

I am trying to access a subset of files from a directory in Dropbox. That directory has more than 25k files (about 200k and growing) and so my initial attempt at building a list of filenames from client.metadata isn't workable. How can one get around this? I can access the filenames from my local copy and periodically update that list. However, because this is a script that a few people in my lab will use, I hoped for something that did not rely on my local copy of Dropbox.

According to the dropbox api, the max amount of files returned from the /metadata api call is 25,000. There is a way to limit the amount of files returned from the api call, but there does not seem a way to list file entries starting from X to Y (like getting entries 100 to 200, then 200 to 300), it seems the only way is to separate these large number of files into folders

Need a way to extract a domain name without the subdomain from a url using Python urlparse. For example, I would like to extract "google.com" from a full url like "http://www.google.com". The closest I can seem to come with urlparse is the netloc attribute, but that includes the subdomain, which in this example would be www.google.com. I know that it is possible to write some custom string manipulation to turn www.google.com into google.com, but I want to avoid by-hand string transforms or regex in this task. (The reason for this is that I am not familiar enough with url formation rules to feel confident that I could consider every edge case required in writing a custom parsing function.) Or, if urlparse can't do what I need, does anyone know any other Python url-parsing libraries that would?

I'm creating a Python class as an API to objects managed remotely via REST. The REST API includes a call that returns a list of dictionaries that define properties of the remote objects. I'm in the process of writing code to dynamically add these properties as attributes of the corresponding Python objects (ie: when the class is instantiated, a REST query is made for a list of properties each of which is then added as an attribute on the instance.) However, this brought back memories of PHP code I'd once glanced at that dynamically added attributes to objects and thinking "have you heard of dictionaries??" Given my background is rooted in C/C++/Java this is a somewhat foreign idea to me, but is perhaps par for the course in Python (and PHP). So, when is it appropriate to dynamically add attributes to an object rather than using a dictionary? From what I've read in related material, it seems to me an API is a legitimate case.

disclaimer: I know nothing about REST ... That said, I would typically be a little hesitant to add attributes to an object willy-nilly for the following reasons: You might accidentally replace some data that you don't want to replace due to a namespace clash dictionaries are easier to inspect rather than having to go through obj.__dict__ or vars(obj) or something similar. There is precedence for adding attributes in the standard library however ... That's basically what argparse does to populate the returned namespace. I think that perhaps it is worth asking the question: "Will the user know which attributes are going to be added to the object?". If the answer to this question is yes, and you're not worried about the afore mentioned namespace conflicts, then perhaps a simple object is appropriate, otherwise, I'd just use a dictionary.

I have two servers. Basically Server #1 runs a script throughout the day and when its done I need to send a notification to Server #2 to get it to run some other scripts. I am currently leaning on Amazon AWS tools and using Python so I was wondering if someone could recommend a simple, secure and easy to program way of: Setting up a flag on Server #1 when it is finished running its script Polling this flag from Server #2 Run scripts on Server #2 when the flag is active Remove the flag from Server #1 when the scripts have finished running on Server #2 Should I be using Amazon SNS or SQS? Alternatively, are these both a poor choice, and if so can you recommend anything better? I am leaning towards AWS tools because I already have boto installed and I like the ease of use.

Assuming Server #1 is running a script through cron, then there should be no reason you can't just use ssh to remotely change Server #2. I believe if you use the elastic-ip addresses it might not count as bandwidth usage. Barring that, I'd use SNS. The model would instead be something like: Server #1 notifies Server #2 (script starting) Server #1 starts running script (optional) Server #1 notifies Server #2 of progress Server #1 notifies Server #2 (script complete), starting Server #2's scripts Server #2 notifies Server #1 when it's complete In this case you'd set up some sort of simple webserver to accept the notifications. Simple CGI scripts would cut it though aren't the most secure option. I'd only bring SQS into the picture if two many scripts were trying to run at once. If you are chunking it "all of Server #1, then Server #2" it's a level you don't really need.

if you are using google chrome, you can check the url which is dynamically being called in network->headers of the developer tools so based on that you can identify whether it is a GET or POST request. If it is a GET request you can find the parameters straight away from the url. If it is a POST request you can find the parameters from form data in network->headers of the developer tools.

I wrote the following function for use in a collection of socket utilities I use for testing. (Using Python 2.7.3, if that's important.) The main reason I pulled the select library into it was so I could implement a timeout instead of just waiting forever for a response. The problem I've found though is that the response is getting truncated at 2048 characters, despite using 64K as the maximum size for the .recv() method on the socket. This truncation didn't happen before I involved select. It happily pulled through 64K and even more when I set the maximum size higher. I've looked through some online resources on select and I find any information on this apparent cap on the size of the received data. I.e. no information that it exists, let alone how to modify it. Can anyone point me to a way to overcome this 2K limit? import socket,select MAXSIZE = 65535 TIMEOUT = 10 def transientConnect(host,port,sendData): error,response = False,'' try: sendSocket = socket.socket() sendSocket.connect((host,port)) sendSocket.send(sendData) gotData = select.select([sendSocket],[],[],TIMEOUT) if (gotData[0]): response = sendSocket.recv(MAXSIZE) else: error = True response = '*** TIMEOUT ***\nNo response from host.' sendSocket.close() except Exception, errText: error,response = True,'*** SOCKET ERROR ***\n'+str(errText) return (error,response)

Store the data manually the very first time (while developing the software). Every 2.5 seconds of running, use polling to check for updated data. If the data is updated, then update the data currently stored. When the user logs on, you plot the chart with the values in the database.

I am currently working on an app that syncs one specific folder in a users Google Drive. I need to find when any of the files/folders in that specific folder have changed. The actual syncing process is easy, but I don't want to do a full sync every few seconds. I am condisering one of these methods: 1) Moniter the changes feed and look for any file changes This method is easy but it will cause a sync if ANY file in the drive changes. 2) Frequently request all files in the whole drive eg. service.files().list().execute() and look for changes within the specific tree. This is a brute force approach. It will be too slow if the user has 1000's of files in their drive. 3) Start at the specific folder, and move down the folder tree looking for changes. This method will be fast if there are only a few directories in the specific tree, but it will still lead to numerous API requests.

As you have correctly stated, you will need to keep (or work out) the file hierarchy for a changed file to know whether a file has changed within a folder tree. There is no way of knowing directly from the changes feed whether a deeply nested file within a folder has been changed. Sorry.

There are a couple of tricks that might help. Firstly, if your app is using drive.file scope, then it will only see its own files. Depending on your specific situation, this may equate to your folder hierarchy. Secondly, files can have multiple parents. So when creating a file in folder-top/folder-1/folder-1a/folder-1ai. you could declare both folder-1ai and folder-top as parents. Then you simply need to check for folder-top.

Since you want to parallelize the requests, you should use requests with grequests (if you're using gevent, or erequests if you're using eventlet). You may have to throttle how quickly you hit the website though since they may do some ratelimiting and be refusing you for requesting too much in too short a period of time.

When doing a scrape of a site, which would be preferable: using curl, or using Python's requests library? I originally planned to use requests and explicitly specify a user agent. However, when I use this I often get an "HTTP 429 too many requests" error, whereas with curl, it seems to avoid that. I need to update metadata information on 10,000 titles, and I need a way to pull down the information for each of the titles in a parallelized fashion. What are the pros and cons of using each for pulling down information?

I'd go for the in-language version over an external program any day, because it's less hassle. Only if it turns out unworkable would I fall back to this. Always consider that people's time is infinitely more valuable than machine time. Any "performance gains" in such an application will probably be swamped by network delays anyway.

Using requests would allow you to do it programmatically, which should result in a cleaner product. If you use curl, you're doing os.system calls which are slower.

So I'm trying to run a search query through the Twitter API in Python. I can get it to return up to 100 results using the "count" parameter. Unfortunately, version 1.1 doesn't seem to have the "page" parameter that was present in 1.0. Is there some sort of alternative for 1.1? Or, if not, does anyone have any suggestions for alternative ways to get a decent amount of tweets returned for a subject. Thanks. Update with solution: Thanks to the Ersin below. I queried as a normally would for a page, and when it's return I would check for the id of the oldest tweet. I'd then use this as the max_id in the next URL.

I think you should use "since_id" parameter in your url. since_id provides u getting pages that older than since_id. So, for the next page you should set the since_id parameter as the last id of your current page.

I'm running some fairly simple tests using browsermob and selenium to open firefox browsers and navigate through a random pages. Each firefox instance is supposed to be independent and none of them share any cookies or cache. On my mac osx machine, this works quite nicely. The browsers open, navigate through a bunch of pages and then close. On my windows machine, however, even after the firefox browser closes, the tmp** folders remain and, after leavin the test going on for a while, they begin to take up a lot of space. I was under the impression that each newly spawned browser would have its own profile, which it clearly does, but that it would delete the profile it made when the browser closes. Is there an explicit selenium command I'm missing to enforce this behaviour? Additionally, I've noticed that some of the tmp folders are showing up in AppData/Local/Temp/2 and that many others are showing up in the folder where I started running the script...

On your mac, have you looked in /var/folders/? You might find a bunch of anonymous*webdriver-profile folders a few levels down. (mine appear in /var/folders/sm/jngvd6s57ldb916b7h25d57r0000dn/T/) Also, are you using driver.close() or driver.quit()? I thought driver.quit() cleans up the temp folder, but I could be wrong.

my apologies if this is a trivial question. I've recently begun doing some android programming and I'm writing a simple app that allows you to use your android device as a controller for your windows PC. Specifically it allows the user to do things like turn off the machine, make it sleep, reboot it etc etc. I'm currently using a python library called CherryPy as a server on the windows machine to execute the actual win32api calls to perform the desired function. What i'm not sure about is how to discover (dynamically) which machine on the network is actually hosting the server. Everything is working fine if I hardcode my machines public IP into the android app, but obviously that is far less than ideal. I've considered having the user manually enter their machines public IP in the app, but if there's a way to, say, broadcast a quick message to all machines on the WiFi and check for a pre-canned response that my Python server would send out, that'd be wonderful. Is that possible? Thanks in advance guys.

Try sending a UDP packet to the special broadcast address 255.255.255.255. Every device in the network should receive a copy of that packet (barring firewalls), and you can arrange to have the server reply to the packet with its identity.

We test an application developed in house using a python test suite which accomplishes web navigations/interactions through Selenium WebDriver. A tricky part of our web testing is in dealing with a series of pdf reports in the app. We are testing a planned upgrade of Firefox from v3.6 to v16.0.1, and it turns out that the way we captured reports before no longer works, because of changes in the directory structure of firefox's temp folder. I didn't write the original pdf capturing code, but I will refactor it for whatever we end up using with v16.0.1, so I was wondering if there' s a better way to save a pdf using Python's selenium webdriver bindings than what we're currently doing. Previously, for Firefox v3.6, after clicking a link that generates a report, we would scan the "C:\Documents and Settings\\Local Settings\Temp\plugtmp" directory for a pdf file (with a specific name convention) to be generated. To be clear, we're not saving the report from the webpage itself, we're just using the one generated in firefox's Temp folder. In Firefox 16.0.1, after clicking a link that generates a report, the file is generated in "C:\Documents and Settings\ \Local Settings\Temp\tmp*\cache*", with a random file name, not ending in ".pdf". This makes capturing this file somewhat more difficult, if using a technique similar to our previous one - each browser has a different tmp*** folder, which has a cache full of folders, inside of which the report is generated with a random file name. The easiest solution I can see would be to directly save the pdf, but I haven't found a way to do that yet. To use the same approach as we used in FF3.6 (finding the pdf in the Temp folder directory), I'm thinking we'll need to do the following: Figure out which tmp*** folder belongs to this particular browser instance (which we can do be inspecting the tmp*** folders that exist before and after the browser is instantiated) Look inside that browser's cache for a file generated immedaitely after the pdf report was generated (which we can by comparing timestamps) In cases where multiple files are generated in the cache, we could possibly sort based on size, and take the largest file, since the pdf will almost certainly be the largest temp file (although this seems flaky and will need to be tested in practice). I'm not feeling great about this approach, and was wondering if there's a better way to capture pdf files. Can anyone suggest a better approach? Note: the actual scraping of the PDF file is still working fine.

We ultimately accomplished this by clearing firefox's temporary internet files before the test, then looking for the most recently created file after the report was generated.

It can be due to an invalid character (due to charset encoding/decoding), therefor BeautifulSoup has issues to parse the input. I solve it by passing my string directly to BeautifulSoup without doing any encoding/decoding. In my case, I was trying to convert UTF-16 to UTF-8 myself.

So I have a webpage that has some javascript that gets executed when a link is clicked. This javascript opens a new window and calls some other javascript which requests an xml document which it then parses for a url to pass to a video player. How can I get that xml response using selenium?

true

14,711,161

1.2

0

1

Short answer, unless the xml is posted to the page, you can't. Long answer, you can use Selenium to do JS injection on the page so that the xml document is replicated to some hidden page element you can expect, or stored to a file locally that you can open. This is, of course, assuming that the xml document is actually retrieved client side; if this is all serverside, you'll need to integrate with the backend or emulate the call yourself. Oh, and one last option to explore would be to proxy the browser Selenium is driving, then inspect the traffic for the response containing the xml. Though more complicated, that actually could be argued to be the best solution, since you aren't modifying the system under test to test it.

We run a bunch of Python test scripts on a group of test stations. The test scripts interface with hardware units on these test stations, so we're stuck running one test script at a time per station (we can't virtualize everything). We built a tool to assign tests to different stations and report test results - this allows us to queue up thousands of tests and let these run overnight, or for any length of time. Occasionally, what we've found is that test stations will drop out of the cluster. When I remotely log into them, I get a black screen, then they reboot, then upon logging in I'm notified that windows XP had a "serious error". The Event Log contains a record of this error, which states Category: (102) and Event ID: 1003. Previously, we found that this was caused by the creation of hundreds of temporary Firefox profiles - our tests use selenium webdriver to automate website interactions, and each time we started a new browser, a temporary Firefox profile was created. We added a step in the cleanup between each test that empties these temporary Firefox profiles, but we're still finding that stations drop out sometime, and always with this serious error and record in the Event Log. I would like to find the root cause of this problem, but I don't know how to go about doing this. I've tried searching for information about how to read event log entries, but I haven't turned up anything that helps. I'm open to any suggestions for ways to go about debugging this issue.

I've experienced similar problems before with Firefox. The rare times that we managed to catch a machine in the act it was just not closing browser sessions. Hence the BSOD eventually. Obviously this was a bug in either webdriver, firefox, or XP (which we were also using). We solved it by aggressively killing every firefox process between each individual test. This worked for us. And because you are not running tests in parallel it would work for you as well. By agressively I mean putting an axe through it. The windows equivalent of killall -9 firefox. Because these sessions were unresponsive. As to the root cause? The problem did not occur with specific versions of Firefox. But we never actually managed to debug it properly. Debugging was very difficult because it wasn't reproducible under short test runs and once the issue arose it really did cause a hard crash.

I am very new to AWS SQS queues and I am currently playing around with boto. I noticed that when I try to read a queue filled with messages in a while loop, I see that after 10-25 messages are read, the queue does not return any message (even though the queue has more than 1000+ messages). It starts populating another set of 10-25 messages after a few seconds or on stopping and restarting the the program. while true: read_queue() // connection is already established with the desired queue. Any thoughts on this behaviour or point me in the right direction. Just reiterating I am just couple of days old to SQS !! Thanks

Long polling is more efficient because it allows you to leave the HTTP connection open for a period of time while you wait for more results. However, you can still do your own polling in boto by just setting up a loop and waiting for some period of time between reading the queue. You can still get good overall throughput with this polling strategy.

Can you do something like this. Im assuming friends of a user is relatively less, and the events attended by a particular user is also much lesser than total number of events. So have a boolean vector of attended events for each friend of the user. Doing a dot product and those that have max will be the friend who most likely resembles the user. Again,.before you do this..you will have to filter some events to keep the size of your vectors manageable.

I don't have any example code to share, but you can definitely use SWF to coordinate the execution of scripts across two servers. The main idea with this is to create three pieces of code that talk to SWF: A component that knows which script to execute first and what to do once that first script is done executing. This is called the "decider" in SWF terms. Two components that each understand how to execute the specific script you want to run on each machine. These are called "activity workers" in SWF terms. The first component, the decider, calls two SWF APIs: PollForDecisionTask and RespondDecisionTaskCompleted. The poll request will give the decider component the current history of an executing workflow, basically the "where am i" state information for your script runner. You write code that looks at these events and figure out which script should execute. These "commands" to execute a script would be in the form of a scheduling of an activity task, which is returned as part of the call to RespondDecisionTaskCompleted. The second components you write, the activity workers, each call two SWF APIs: PollForActivityTask and RespondActivityTaskCompleted. The poll request will give the activity worker an indication that it should execute the script it knows about, what SWF calls an activity task. The information returned from the poll request to SWF can include single execution-specific data that was sent to SWF as part of the scheduling of the activity task. Each of your servers would be independently polling SWF for activity tasks to indicate the execution of the local script on that host. Once the worker is done executing the script, it calls back to SWF through the RespondActivityTaskCompleted API. The callback from your activity worker to SWF results in a new history being handed out to the decider component that I already mentioned. It will look at the history, see that the first script is done, and schedule the second one to execute. Once it sees that the second one is done, it can "close" the workflow using another type of decision. You kick off the whole process of executing the scripts on each host by calling the StartWorkflowExecution API. This creates the record of the overall process in SWF and kicks out the first history to the decider process to schedule the execution of the first script on the first host. Hopefully this gives a bit more context on how to accomplish this type of workflow using SWF. If you haven't already, I would take a look at the dev guide on the SWF page for additional info.

To use python libraries, you must have development version of python like python2.6-dev, which can be installed using sudo apt-get install python2.6-dev. Then you may install any additional development libraries that you want in your code to run. Whatever you install using sudo apt-get install python-paramkio or python setup.py install will then be available to you.

Do an online search for a listing of "Proxy services" from the internet. You can then loop through them as proxies in Python. There are companies that maintain open proxy networks , and across multiple continents , to help people get past GEO-IP restrictions. You can also configure different servers you control on the internet to act as remote proxies for your needs. Don't use TOR for this project, which has legitimate uses and needs... and has bad bandwidth already. There are rarely any legitimate uses for doing stuff like this. There are also shady publishers of "Open Proxy" lists - basically a daily updated list of wrongly configured apache instances that can reroute requests. Those are often used by people trying to increase ad impressions / pagecounts or fake online voting contests. ( which are the two main things people want to do with open proxies and repeated 'new' visits )

So the answer is that on windows proxy system settings are stored in the registry under HKEY_CURRENT_USER So as the service runs under a special user it can't find it in its HKEY_CURRENT_USER. The solutions: 1. Run the service under another user. 2. Read the proper user registry

It turns out that the problem itself wasn't BeautifulSoup, but the dynamics of the page itself. For this specific scenario that is. The page returns part of the page, so headers need to be analysed and sent to the server accordingly. This isn't a BeautifulSoup problem itself. Therefore, it is important to take a look at how the data is loaded on a specific site. It's not always a "Load a whole page, process the whole page" paradigm. In some cases, you need to load part of the page and send a specific parameter to the server in order to keep loading the rest of the page.

Basically you can't tell that the user has left your site on the server-side. The common way to do what you want to achieve is to use a time limit after the last known request as a cutoff between the online/offline states. To make this more accurate you can have a script on the client-side that does regular AJAX polling, if you must consider that a user is online long after their last request while your site is still open in a tab. If you must check that the user has the tab active, make that request conditional on recent mouse or keyboard events.

I am having a hard time installing lxml(3.1.0) on python-3.3.0.

You should probably mention the specific operating system you're trying to install on, but I'll assume it's some form of Linux, perhaps Ubuntu or Debian since you mention apt-get. The error message you mention is typical on lxml when the libxml2 and/or libxslt libraries are not installed for it to link with. For whatever reason, the install procedure does not detect when these are not present and can give the sense the install has succeeded even though those dependencies are not satisfied. If you issue apt-get install libxml2 libxml2-dev libxslt libxslt-dev that should eliminate this error.

I'm trying to create a list of dicts with two data items. The page I'm looking at has 37 matches for //div[@id='content']/*[self::p or self::h2]/a[2]; however, it only has 33 matches for //div[@id='content']/*[self::p or self::h2]/a[contains(@href,'game')]/img[@src] The two xpaths have //div[@id='content']/*[self::p or self::h2] in common. I effectively only want to get the element matched for the first xpath if the second xpath is matched, and leave the 4 without the second element behind. I'm hoping that this can be accomplished with xpath but if not, could use some advice on writing a function that achieves this in python.

What you want to do is called Single sign on (SSO) and it's much easier to implement on actual web server than Django. So, you should check how to do SSO on Apache/Nginx/whateverYouAreUsing, then the web server will forward the authenticated username to your django app.

Using Redis with our Python WSGI application, we are noticing that at certain intervals, Redis stops responding to requests. After some time, however, we are able to fetch the values stored in it again. After seeing this situation and checking the status of the Redis service, it is still online. If it is of any help, we are using the redis Python package and using StrictRedis as a connection class, with a default ConnectionPool. Any ideas on this will be greatly appreciated. If there is more information which will help better diagnose the problem, let me know and I'll update ASAP. Thanks very much!

More data about your redis setup and the size of the data set would be useful. That said I would venture to guess your Eedis server is configured to persist data to disk (the default). If so you could be seeing your Redis node getting a bit overwhelmed whenit forks off a copy of itself to save the data set to disk. If this is the case and you do need to persist to disk then I would recommend a second instance be stood up and configured to be a shave to the first one and persist to disk. The master you would then configure to not persist to disk. In this configuration you should see the writable node be fully responsive at all times. You could even go so far as to setup a Non-persisting slave for read-only access. But without more details on your configuration, resources, and usage it is merely an educated guess.

I have a small python program to help my colleagues to analyse some tsv data. The data is not big, usually below 20MB. I developed the GUI with PyQT. I want to change this desktop program to a web app so my colleagues don't have to upgrade the program every time I change it or fix a bug. They can just go to a website and use Chrome as the GUI. So how do I do this? I spend most of my time developing desktop program and just know some basic web developing knowledges. I have read some framework such as flask and web2py, and know how to use HTML and Javascript to make buttons but no clue to achieve my purpose. Can someone give me a practical way to do this? It'd be better if the user don't have to upload the local data to the server. Maybe just download the python code from server then execute in Chrome. Is this possible? Thanks.

The whole point of a web application is that the GUI is written in HTML, CSS, and JavaScript, not Python. However, it talks to a web service, which can be written in Python. For a well-written desktop app, the transition should be pretty easy. If you've already got a clean separation between the GUI part and the engine part of your code, the engine part will only need minor changes (and maybe stick it behind, e.g., a WSGI server). You will have to rewrite the GUI part for the web, but in a complex app, that should be the easy part. However, many desktop GUI apps don't have such a clean separation. For example, if you have button handlers that directly do stuff to your model, there's really no way to make that work without duplicating the model on both sides (the Python web service and the JS client app) and synchronizing the two, which is a lot of work and leads to a bad experience. In that case, you have to decide between rewriting most of your app from scratch, or refactoring it to the point where you can web-service-ify it. If you do choose to go the refactoring route, I'd consider adding a second local interface (maybe using the cmd module to build a CLI, or tkinter for an alternate GUI), because that's much easier to do. Once the same backend code can support your PyQt GUI and your cmd GUI, adding a web interface is much easier.

No, you cannot run Python code in a web browser.[1] You'd have to port the core of your application to JavaScript to do it all locally. Just do the upload. 20MB isn't all that much data, and if it's stored on the server then they can all look at each others' results, too. [1] There are some tools that try to transpile Python to JavaScript: pyjs compiles directly, and Emscripten is an entire LLVM interpreter in JS that can run CPython itself. I wouldn't really recommend relying on these.

If I get your point correctly, you want Web connection, so your python program updated on server, client get it before using it. Data store on local to avoid upload big file. You can write a python program to check a server location to get your latest program if needed. You need a url / server file for program version / created date/time information to determine if you need to update or not. After get latest python program, then start this python program to run locally. With this said, What you need is to update your program to add below features: Access your server, to get latest version information Check against current version to see if you need to download latest program Download latest version and use that to run locally. Does this solve your problem?

It seems the socket connection through paramiko (v1.10.0) is not stable. I have two computers. The python code is on the PC one. The connection sometime is successful and sometime is not (Same code). When the PC paramiko code fails (socket.error, 10060), I use my Mac via terminal ssh login the server and everything is fine. I use set_missing_host_key_policy in the code. But the Mac has the key I guess. I typed yes when login at the first time. If the unstable connection is caused by the hotkey, how do I get the host key?

If polling is not an option, you can think about the better technique, WebSockets, if your server supports it (and your target browser!). One way or another, you need a connection opened by the client to the server, though.

An SVG file is basically an XML file so I could use the string <?xml (or the hex representation: '3c 3f 78 6d 6c') as a magic number but there are a few opposing reason not to do that if for example there are extra white-spaces it could break this check.

I'm going to run a small server inheriting from Python.SocketServer.TCPServer. In case the code is too slow, I could make it threaded or just expand the queue size, and it will take a bit longer to run.

Depending on your OS, the maximum value for request_queue_size will be 128 (that's the default maximum size on Linux and Mac OS X, at least). Higher values won't give an error but will just silently be limited. Higher values won't necessarily be a problem I think, although I would seriously consider using some form of threading (or, if appropriate, an asynchronous solution using gevent or something similar). The SocketServer module provides mixins for creating threaded or forking socket servers.

You can query the last build timestamp to determine if the build finished. Compare it to what it was just before you triggered the build, and see when it changes. To get the timestamp, add /lastBuild/buildTimestamp to your job URL As a matter of fact, in your Jenkins, add /lastBuild/api/ to any Job, and you will see a lot of API information. It even has Python API, but I not familiar with that so can't help you further However, if you were using XML, you can add lastBuild/api/xml?depth=0 and inside the XML, you can see the <changeSet> object with list of revisions/commit messages that triggered the build

I use to program on python. I have started few months before, so I am not the "guru" type of developer. I also know the basics of HTML and CSS. I see few tutorials about node.js and I really like it. I cannot create those forms, bars, buttons etc with my knowledge from html and css. Can I use node.js to create what user see on browser and write with python what will happen if someone push the "submit" button? For example redirect, sql write and read etc. Thank you

I think you're thinking about this problem backwards. Node.js lets you run browser Javascript without a browser. You won't find it useful in your Python programming. You're better off, if you want to stick with Python, using a framework such as Pyjamas to write Javascript with Python or another framework such as Flask or Twisted to integrate the Javascript with Python.

Is it possible to make selenium use the TOR browser? Does anyone have any code they could copy-paste?

false

15,316,304

0

I looked into this, and unless I'm mistaken, on face value it's not possible. The reason this cannot be done is because: Tor Browser is based on the Firefox code. Tor Browser has specific patches to the Firefox code to prevent external applications communicating with the Tor Browser (including blocking the Components.Interfaces library). The Selenium Firefox WebDriver communicates with the browser through Javascript libraries that are, as aforementioned, blocked by Tor Browser. This is presumably so no-one outside of the Tor Browser either on your box or over the internet knows about your browsing. Your alternatives are: Use a Tor proxy through Firefox instead of the Tor Browser (see the link in the comments of the question). Rebuild the Firefox source code with the Tor Browser patches excluding those that prevent external communication with Tor Browser. I suggest the former.

You can run multiple instances of IDLE/Python shell at the same time. So open IDLE and run the server code and then open up IDLE again, which will start a separate instance and then run your client code.

I need to make a simple p2p vpn app, after a lot of searches I found a tun/tap module for python called PYTUN that is used to make a tunnel. How can I use this module to create a tunnel between 2 remote peers? All the attached doc only show how to make the tunnel interface on your local computer and config it, but it does not mention how to connect it to the remote peer.

pytun is not sufficient for this. It serves to connect your Python application to a system network interface. In effect, you become responsible for implementing that system network interface. If you want traffic that is routed over that network interface to traverse an actual network, then it is the job of your Python program to do the actual network operations that move the data from host A to host B. This is probably a lot of work to do well. I suggest you use an existing VPN tool instead.

I want to write a little program that will give me an update whenever a webpage changes. Like I want to see if there is a new ebay listing under a certain category and then send an email to myself. Is there any clean way to do this? I could set up a program and run it on a server somewhere and have it just poll ebay.com every couple of minutes or seconds indefinitely but I feel like there should be a better way. This method could get dicey too if I wanted to monitor a variety of pages for updates.

There is no 'clean' way to do this. You must relay on CURL or file_get_context() with context options in order to simply get data from URL, and, in order to notify you when content of URL is changed, you must store in database snapshots of page you are listening. Lately you are comparing new version of crawled content with earlier created snapshot and, if change in significant parts of DOM are detected, that should be trigger for your mail notifier function.

I have an app that consists of a local "server" and a GUI client. The server is written in Python, while the GUI is meant to be changable, and is written in Flex 4. The client queries the local server for information and displays it accordingly. Both applications are meant to be run on the same computer, and will only communicate locally. At the moment, the client and the Python server communicates via a basic socket, the client writes a request to the socket, and the socket returns some data. However, since I'm writing a desktop app, I thought it might be easier to maintain and to polish a system that uses standard streams instead of a socket. The server would listen for raw_input() continuously, and output according to anything written to stdin, and the client, in this case, would use AIR's NativeProcess class to read and write to stdout and stdin, rather than using sockets. The client and server are separate processes, but are meant to be started at more or less the same time. I don't really have need for complex networking, just local cross-language communication. What are the pros and cons of each approach? What would I gain or lose from using sockets, vs what I would gain or lose from using standard streams to communicate? Which one is more efficient? Which one is easier to maintain?

On UNIX-like platforms, using stdin/stdout is a socket, so there's no difference. That is, if you launch a process with its stdout redirected, that'll typically be done with socketpair, so making your own UNIX-domain socket to communicate is unnecessary. The Python classes for handling stdin/stdout won't give you access to the full flexibility of the underlying socket though, so you'll have to set it up yourself I think if you want to do a half-close, for example (Python can't offer that cross-platform because the Windows sys::stdin can't be a socket, for example, nor is it always on UNIX.) The nice thing about a local TCP connection is that it's cross-platform, and gives predictable semantics everywhere. If you want to be able to close your output and still read from the input, for example, it's much simpler to do this sort of thing with sockets which are the same everywhere. Even without that, for simplicity's sake, using a TCP socket is always a reasonable way to work around the wacky Windows mess of named pipes, although Python shields you from that reasonably well.

I have two Python files that I want to prevent anyone from executing unless it's from the server itself. The files implement a function that increases an amount of money to a user. What I need is to make this file not public to the web, so that if someone tries to call this file, the file would refuse this request, unless the call is from the server. Does anyone know how I can do this? My first idea was to check for the IP address but a lot of people can spoof their IP. Example Let's say I have this file: function.py, a function in this file will accept a new amount of money and increase the appropriate balance in the database. When someone tries to post data to this file, and this person is outside the server (lets say from 244.23.23.0) the file will be in-accessible. Whereas, calling the function from the server itself will be accepted. So files can access other files on the server, but external users cannot, with the result that no one can execute this file unless it's called from the server. This is really important to me, because it's related to real money. Also, the money will come from PayPal IPN. And actually, if there was a way to prevent access unless it was coming from PayPal, that would be an amazing way to secure the app. OK, as far as what I have tried: Put the database in a cloud SQL using Google [https://developers.google.com/cloud-sql/] Try to check the IP of the incoming request, in the file Thanks for any and all help.

You could use some HTTP sniffer (like fiddler) or any protocol sniffer (tcpdump, wireshark) to sniff your network traffic to Google and check if your urllib request and wget/browser requests differ. Also check and compare all the cookies and HTTP-headers of both requests. And remember , that for IPs with big number of requests to Google - google sends captcha every N requests , so if you need to parse it's content - you possibly need to use some proxies for Google parsing.

No, there really isn't any way to do this without putting some sort of service between the people clicking on the links and the S3 objects. The reason is that access to the S3 content is determined by your AWS access_key and secret_key. There is no way to "login" with these credentials and logging into the AWS web console uses a different set of credentials that are only useful for the console. It does not authenticate you with the S3 service.

I want to be able to get the list of all URLs that a browser will do a GET request for when we try to open a page. For eg: if we try to open cnn.com, there are multiple URLs within the first HTTP response which the browser recursively requests for. I'm not trying to render a page but I'm trying to obtain a list of all the urls that are requested when a page is rendered.

I guess you will have to create a list of all known file extensions that you do NOT want, and then scan the content of the http response, checking with "if substring not in nono-list:" The problem is all href's ending with TLDs, forwardslashes, url-delivered variables and so on, so i think it would be easier to check for stuff you know you dont want.

Please help me solve following case: Imagine a typical classified category page. A page with list of items. When you click on items you land on internal pages.Now currently my crawler scrapes all these URLs, further scrapes these urls to get details of the item, check to see if the initial seed URL as any next page. If it has, it goes to the next page and do the same. I am storing these items in a sql database. Let say 3 days later, there are new itmes in the Seed URL and I want to scrap only new items. Possible solutions are: At the time of scraping each item, I check in the database to see if the URL is already scraped. If it has, I simply ask Scrapy to stop crawling further. Problem : I don't want to query database each time. My database is going to be really large and it will eventually make crawling super slow. I try to store last scraped URL and pass it on in the beginning, and the moment it finds this last_scraped_url it simply stops the crawler. Not possible, given the asynchronous nature of crawling URLs are not scraped in the same order they are received from seed URLs. ( I tried all methods to make it in orderly fashion - but that's not possible at all ) Can anybody suggest any other ideas ? I have been struggling over it for past three days. Appreciate your replies.

Before trying to give you an idea... I must say I would try first your database option. Databases are made just for that and, even if your DB gets really big, this should not do the crawling significantly slow. And one lesson I have learned: "First do the dumb implementation. After that, you try to optimize." Most of times when you optimize first, you just optimize the wrong part. But, if you really want another idea... Scrapy's default is not to crawl the same url two times. So, before start the crawling you can put the already scraped urls (3 days before) in the list that Scrapy uses to know which urls were already visited. (I don't know how to do that.) Or, simpler, in your item parser you can just check if the url was already scraped and return None or scrape the new item accordingly.

I've created an XMPP chat client in python. Chat generally works except it seems that Google Talk 'blocks' some messages when sending from my chat client to a user using Google Talk. For example, if I send the same one word message 'hi' multiple times to gtalk user, it only displays it once. However, when sending that same sequence of messages to a user on iChat or on Adium, all of the 'hi's get shown. Sometimes, Google Talk also doesn't display the first 1-2 incoming messages from my client. Otherwise, chatting works. My client never has any trouble with incoming chats. Thoughts?

In case it helps anyone, I figured it out. You just need to specify an id attribute in each chat message. They can be random id's but each message should have a different one. I assume gtalk was 'blocking' repeated messages b/c it couldn't tell if the messages were distinct or just repeats without an id.

Selenium isn't actually a testing framework, it's a browser driver. You don't write tests in Selenium any more than you write GUI apps in OpenGL. You usually write tests in a unit testing framework like unittest, or something like nose or lettuce built on top of it. Your tests then use Selenium to interact with a browser, as they use a database API to access the DB or an HTTP library to communicate with web services.

I wonder, what is the advantage of using selenium for automation if at the end of the test he emits no reports where the test passed or failed?

Its up to the discretion of the user what to do with the selenium webdriver automation and how to report the test results. Selenium webdriver will give you the power to control your web browser and to automate your web application tests. Same as how you have to program in any other automation tool the conditions for checking your pass or fail criteria for any tests, in Selenium also it has to be programmed.It is totally up to the programmer how to report their results and the template to be followed. You will have to write your own code to format and store the test results.

I have implemented GCM using my own sever. Now I'm trying to do the same using Python 2.7 in Google App Engine. How can I get the IP address for the server hosting my app? (I need it for API Key). Is IP-LookUp only option? And if I do so will the IP address remain constant?

You can check the IP easily by doing a ping from the command line to the domain name, as in "ping appspot.com". With this you will obtain the response from the real IP. Unfortunately this IP will change over time and won't make your GCM service work. In order to make it work you only need to leave the allowed IPs field blank.

I have a Python script which produces some some data. I would like to stream it to an HTTP server using POST. That is, I don't want to accumulate the data in a buffer and then send it -- I just want to send it as it's created. There will be a lot. The apparently obvious way to do this would be to open the HTTP connection in some way that return a writeable file object, write the data to that object, and then close the connection. However, it's not obvious to me that this is supported in any of the libraries I looked at (urllib2, httplib, and requests). How can I accomplish this?

You wont get a writeable file object via urllib2 / urllib. The return value is a "file like" object which supports iteration and reading. If you can read the contents and create your own file object for writing.

I have a large local file. I want to upload a gzipped version of that file into S3 using the boto library. The file is too large to gzip it efficiently on disk prior to uploading, so it should be gzipped in a streamed way during the upload. The boto library knows a function set_contents_from_file() which expects a file-like object it will read from. The gzip library knows the class GzipFile which can get an object via the parameter named fileobj; it will write to this object when compressing. I'd like to combine these two functions, but the one API wants to read by itself, the other API wants to write by itself; neither knows a passive operation (like being written to or being read from). Does anybody have an idea on how to combine these in a working fashion? EDIT: I accepted one answer (see below) because it hinted me on where to go, but if you have the same problem, you might find my own answer (also below) more helpful, because I implemented a solution using multipart uploads in it.

There really isn't a way to do this because S3 doesn't support true streaming input (i.e. chunked transfer encoding). You must know the Content-Length prior to upload and the only way to know that is to have performed the gzip operation first.

I wrote a little download manager in python, and now i want to "catch" downloads from Chrome Firefox and Explorer so they will download with it, instead of each built-in download manager of the browser itself. I want to know when each of the browsers are starting a file download, so i can prevent the default behavior and use my own manager. All i need to start a download myself is the file url of course. I know that in the past there were popular download managers such as "Get Right" that did exactly this. I want to do something similar. Any ideas how would i go about doing this?

Each of the web browsers e.g. Firefox, Chrome, IE, Safari, all have plugin models. If you are going to truly integrate your manager into the web browsers, you will need to examine their plugin models, and make your download manager work through that.

I have an email interface client, and I am using IMAP for my requests. I want to be able to show, in real-time, basic email data, for a list view. As in, for example, the GMail list view. For that, I need to do an IMAP request to obtain the subject of all emails, the date of all emails, etc. This works so far. The problem is, I want to also show the first characters of the body text. If I use the BODYSTRUCTURE call to obtain the index of the text/HTML part it takes too long (for emails with thousands of characters it might take well over a second per email, while using only the subject/date/etc calls takes about 0.02 seconds max. I tried using the BODY[INDEX]<0.XYZ> bytes where XYZ is the number of the first bytes we want to obtain, but to my dismay, it takes as long as using the BODY[INDEX] call. Sometimes even more. Is there another way to obtain the first text characters, but in a quick manner? If I want to list 300 emails on my interface I cannot afford to spend 1 second per email just to obtain the first text characters. I'm using Python with imaplib for this, even though probably not relevant.

If you really want to fetch the beginning of the first textual part of a message, you will have to parse the BODYSTRUCTURE. After you obtain the part ID of the desired textual part, use the BODY[number]<0.size> syntax. The suggestion given in the other answer will fail on multipart messages (like if you have a text/plain and text/html, which is most common format today.
