• Java code critique request [closed]

  - by davidk01

  Can you make sense of the following bit of java code and do you have any suggestions for improving it? Instead of writing four almost identical setOnClickListener method calls I opted to iterate over an array but I'm wondering if this was the best way to do it. Here's the code: /* Set up the radio button click listeners so two categories are not selected at the same time. When one of them is clicked it clears the others. */ final RadioButton[] buttons = {radio_books,radio_games,radio_dvds,radio_electronics}; for (int i = 0; i < 4; i++) { final int k = i; buttons[i].setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { for (int j = 0; j < 4; j++) { if (buttons[j] != buttons[k]) { buttons[j].setChecked(false); } } } }); }

• Nginx + Haproxy + Thin + Rails - 503 Service Unavailable -

  - by Luca G. Soave

  I don't know how troubleshoot this. I get "503 Service Unavailable" http error for all "nginx upstreams" proxy passing calls to haproxy fast_thin and slow_thin ( server 127.0.0.1:3100 and server 127.0.0.1:3200 ), which loadbalance on 6 Thin servers ( 127.0.0.1:3000 .. 3005 ). Static files like /blog are currently fine. The falldown is: nginx on port 80 - haproxy on 3100 and 3200 - thin on 3000 .. 3005 and then Rails.

• Should we enforce code style in our large codebase?

  - by eighttrackmind

  By "code style" I mean 2 things: Style, eg. // bad if(foo){ ... } // good if (foo) { ... } Conventions and idiomaticity, where two ways of writing the same thing are functionally equivalent, but one is more idiomatic. eg. // bad if (fooLib.equals(a, b)) { ... } // good if (a == b) { ... } I think it makes sense to use an auto-formatter to enforce #1 automatically. So my question is specifically about #2. I like to break things down into pros and cons, here's what I've come up with so far: Pros: Used by many large codebases (eg. Google, jQuery) Helps make it a bit easier to work on new areas of the codebase Helps make code more portable (this is not necessarily true) Code style is automatic once you get used to it Makes it easier to fast-decline pull requests Cons: Takes engineers’ and code reviewers’ time away from more important things (like developing features) Code should ideally be rewritten every 2-3 years anyway, so it’s more important to focus on getting the architecture right, and achieving high test coverage Adds strain to code reviews (eg. “don’t do it this way, I like this other way better”) Even if I’ve been using a code style for a while, I still sometime have to pause and think about how to write a line better Having an enforced, uniform code style makes it hard to experiment with potentially better styles Maintaining a style guide takes a lot of incremental effort Engineers rarely read through the style guide. More often, it's cited in code reviews And as a secondary question: we also have many smaller repositories - should the same code style be enforced there?

• When to use HTTP status code 404 in an API

  - by Sybiam

  I am working on a project and after arguing with people at work for about more than a hour. I decided to know what people on stack-exchange might say. We're writing an API for a system, there is a query that should return a tree of Organization or a tree of Goals. The tree of Organization is the organization in which the user is present, In other words, this tree should always exists. In the organization, a tree of goal should be always present. (that's where the argument started). In case where the tree doesn't exist, my co-worker decided that it would be right to answer response with status code 200. And then started asking me to fix my code because the application was falling apart when there is no tree. I'll try to spare flames and fury. I suggested to raise a 404 error when there is no tree. It would at least let me know that something is wrong. When using 200, I have to add special check to my response in the success callback to handle errors. I'm expecting to receive an object, but I may actually receive an empty response because nothing is found. It sounds totally fair to mark the response as a 404. And then war started and I got the message that I didn't understand HTTP status code schema. So I'm here and asking what's wrong with 404 in this case? I even got the argument "It found nothing, so it's right to return 200". I believe that it's wrong since the tree should be always present. If we found nothing and we are expecting something, it should be a 404. More info, I forgot to add the urls that are fetched. Organizations /OrgTree/Get Goals /GoalTree/GetByDate?versionDate=... /GoalTree/GetById?versionId=... My mistake, both parameters are required. If any versionDate that can be parsed to a date is provided, it will return the closes revision. If you enter something in the past, it will return the first revision. If by Id with a id that doesn't exists, I suspect it's going to return an empty response with 200. Extra Also, I believe the best answer to the problem is to create default objects when organizations are created, having no tree shouldn't be a valid case and should be seen as an undefined behavior. There is no way an account can be used without both trees. For that reasons, they should be always present. also I got linked this (one similar but I can't find it) http://viswaug.files.wordpress.com/2008/11/http-headers-status1.png

• svn 503 error when commit new files

  - by philipp

  I am struggling with a strange error when I try to commit my repository. I have a V-server with webmin installed on it. Via Webmin I installed an svn module, created repositories and everything worked fine until three days ago. Trying to commit brings the following error: Commit failed (details follow): Server sent unexpected return value (503 Service unavailable) in response to PROPFIND request for '/svn/rle/!svn/wrk/a1f963a7-0a33-fa48-bfde-183ea06ab958/RLE/.htaccess' Server sent unexpected return value (503 Service unavailable) in response to PROPFIND request for '/svn/rle/RLE/.htaccess' I google everywhere and found only very few solutions. One indicated that a wrong error document is set, another one dealt about the problem that filenames might cause this error and last but not least a wrong proxy configuration in the local svn config could be the reason. After trying all of the solutions suggested I could not reach anything. Only after a server reboot there was a little difference in the error-message, telling me that the server was not able to move a temp file, because the operation was permitted. So I also controlled the permissions of the svn directory, but also with no success. An svn update than restored the "normal" error from above and nothing changed since then. The only change I made on the server, I guess that this could be the reason why svn does not work anymore, was to install the php5_mysql module for apache via apt-get install php5_mysql. Atg the moment I have totally no idea where I could search. I don't know if the problem is on my server or in my repository and I would be glad to get any hint to solve this. Thanks in advance Greetings philipp error log: [Tue Oct 25 19:23:02 2011] [error] [client 217.50.254.18] Could not create activity /svn/rle/!svn/act/d8dd436f-d014-f047-8e87-01baac46a593.

I also created a second repository and tried to commit files in there, what gave me the same error.

  I'm frequently getting 503 Service Unavailable when I have limit_req turned on.

• Is code maintenance typically a special project, or is it considered part of daily work?

  - by blueberryfields

  Earlier, I asked to find out which tools are commonly used to monitor methods and code bases, to find out whether the methods have been getting too long. Most of the responses there suggested that, beyond maintenance on the method currently being edited, programmers don't, in general, keep an eye on the rest of the code base. So I thought I'd ask the question in general: Is code maintenance, in general, considered part of your daily work? Do you find that you're spending at least some of your time cleaning up, refactoring, rewriting code in the code base, to improve it, as part of your other assigned work? Is it expected of you/do you expect it of your teammates? Or is it more common to find that cleanup, refactoring, and general maintenance on the codebase as a whole, occurs in bursts (for example, mostly as part of code reviews, or as part of refactoring/cleaning up projects)?

• HAProxy "503 Service Unavailable" for webserver running on a KVM virtual machine

  - by Menda

  I'm setting up a server with KVM (IP 192.168.0.100) and I have created inside of it one virtual machine using network bridging at 192.168.0.194. This virtual machine has an nginx instance running, which I can access from the server or from any computer computer in the internal network just typing in the browser http://192.168.0.194. However, I try configure HAProxy in the same server that hosts KVM and looking the status page of HAProxy it always shows the virtual machine as "DOWN". If I try from the server http://localhost, it should be the same than if I go to http://192.168.0.194. My goal is to build a reverse proxy, but I tried this little example and won't work. What am I doing bad? This is my config file in the server: # /etc/haproxy/haproxy.cfg global maxconn 4096 user haproxy group haproxy daemon defaults log global mode http option httplog option dontlognull retries 3 option redispatch maxconn 2000 contimeout 5000 clitimeout 50000 srvtimeout 50000 listen ServerStatus *:8081 mode http stats enable stats auth haproxy:haproxy listen Server *:80 mode http balance roundrobin cookie JSESSIONID prefix option httpclose option forwardfor option httpchk HEAD /check.txt HTTP/1.0 server mv1 192.168.0.194:80 cookie A check Thanks.

• A Web exception occurred because an HTTP 503 - ServiceUnavailable response was received from Unknown

  - by Dai

  As far as I can tell my Exchange 2010 Mailbox and Client Access server is working fine except for Outlook Anywhere. I fired up the Exchange Connectivity Tester and ran it against my server and I get this report: Part 5 Testing HTTP Authentication Methods for URL https://mail.contoso.com/rpc/rpcproxy.dll?server6.corp.contoso.com:6002. The HTTP authentication test failed. Additional details: A Web exception occurred because an HTTP 503 - ServiceUnavailable response was received from Unknown. When I do a search for "ServiceUnavailable response was received from Unknown." I get only a couple of relevant results, including a 22k-view Exchange Forum thread, but none of the solutions discussed help. There is nothing of relevance in the server's Event Log. mail.contoso.com is the public domain name of the CAS/MB/HT server. server6.corp.contoso.com is the internal domain name of the server.

  I'm having issues with my ColdFusion 9 server, it continuously keeps crashing. When I go to a web page from my application I am getting a "503 Jrun Servlet Error". Does anyone have any clue to why this is happening? It appears that my memory is being consumed greatly and causing my server to crash. I read somewhere about setting this setting to false "cfset This.Clientmanagement="false"". Any ideas about any of this? All suggestions would be a tremendous help. Thanks much. tone

• HTTP Builder/Groovy - lost 302 (redirect) handling?

  - by Misha Koshelev

  Dear All: I am reading here http://groovy.codehaus.org/modules/http-builder/doc/handlers.html "In cases where a response sends a redirect status code, this is handled internally by Apache HttpClient, which by default will simply follow the redirect by re-sending the request to the new URL. You do not need to do anything special in order to follow 302 responses." This seems to work fine when I simply use the get() or post() methods without a closure. However, when I use a closure, I seem to lose 302 handling. Is there some way I can handle this myself? Thank you p.s. Here is my log output showing it is a 302 response [java] FINER: resp.statusLine: "HTTP/1.1 302 Found" Here is the relevant code: // Copyright (C) 2010 Misha Koshelev.

• How to test an HTTP 301 redirect?

  - by NoozNooz42

  How can one easily test HTTP return codes, like, say, a 301 redirect? For example, if I want to "see what's going on", I can use telnet to do something like this: ... $ telnet nytimes.com 80 Trying 199.239.136.200... Connected to nytimes.com. Escape character is '^]'. GET / HTTP/1.0 (enter) (enter) HTTP/1.1 200 OK Server: Sun-ONE-Web-Server/6.1 Date: Mon, 14 Jun 2010 12:18:04 GMT Content-type: text/html Set-cookie: RMID=007af83f42dd4c161dfcce7d; expires=Tuesday, 14-Jun-2011 12:18:04 GMT; path=/; domain=.nytimes.com Set-cookie: adxcs=-; path=/; domain=.nytimes.com Set-cookie: adxcs=-; path=/; domain=.nytimes.com Set-cookie: adxcs=-; path=/; domain=.nytimes.com Expires: Thu, 01 Dec 1994 16:00:00 GMT Cache-control: no-cache Pragma: no-cache Connection: close <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> ... Which is an easy way to access quite some infos. But now I want to test that a 301 redirect is indeed a 301 redirect. How can I do so? Basically, instead of getting a HTTP/1.1 200 OK I'd like to know how I can get the 301? I know that I can enter the name of the URL in a browser and "see" that I'm redirected, but I'd like to know what tool(s) can be used to actually really "see" the 301 redirect. Btw, I did test with a telnet, but when I enter www.example.org, which I redirected to example.org (without the www), all I can see is an "200 OK", I don't get to see the 301.

• HTTP 1.0 vs 1.1

  - by Jason Baker

  Could somebody give me a brief overview of the differences between HTTP 1.0 and HTTP 1.1? I've spent some time with both of the RFCs, but haven't been able to pull out a lot of difference between them. Wikipedia says this: HTTP/1.1 (1997-1999) Current version; persistent connections enabled by default and works well with proxies. Also supports request pipelining, allowing multiple requests to be sent at the same time, allowing the server to prepare for the workload and potentially transfer the requested resources more quickly to the client. But that doesn't mean a lot to me. I realize this is a somewhat complicated subject, so I'm not expecting a full answer, but can someone give me a brief overview of the differences at a bit lower level? By this I mean that I'm looking for the info I would need to know to implement either an HTTP server or application. I realize that this can be a somewhat complicated subject (based on what I know about HTTP as of right now), so I'm not necessarily looking for a full answer. I'm really more looking for a nudge in the right direction so that I can figure it out on my own.

• Git push over http (using git-http-backend) and Apache is not working

  - by Ole_Brun

  I have desperately been trying to get push for git working through the "smart-http" mode using git-http-backend. However after many hours of testing and troubleshooting, I am still left with error: Cannot access URL http://localhost/git/hello.git/, return code 22 fatal: git-http-push failed` I am using latest versions of Ubuntu (12.04), Apache2 (2.2.22) and Git (1.7.9.5) and have followed different tutorials found on the Internet, like this one http://www.parallelsymmetry.com/howto/git.jsp. My VHost file currently looks like this: <VirtualHost *:80> SetEnv GIT_PROJECT_ROOT /var/www/git SetEnv GIT_HTTP_EXPORT_ALL SetEnv REMOTE_USER=$REDIRECT_REMOTE_USER DocumentRoot /var/www/git ScriptAliasMatch \ "(?x)^/(.*?)\.git/(HEAD | \ info/refs | \ objects/info/[^/]+ | \ git-(upload|receive)-pack)$" \ /usr/lib/git-core/git-http-backend/$1/$2 <Directory /var/www/git> Options +ExecCGI +SymLinksIfOwnerMatch -MultiViews AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> I have changed the ownership of the /var/www/git folder to root.www-data and for my test repositories I have enabled anonymous push by doing git config http.receivepack true. I have also tried with authenticated users but with the same outcome. The repositories were created using: sudo git init --bare --shared [repo-name] While looking at the apache2 access.log, it appears to me that WebDAV is trying to be used, and that git-http-backend is never fired: 127.0.0.1 - - [20/May/2012:23:04:53 +0200] "GET /git/hello.git/info/refs?service=git-receive-pack HTTP/1.1" 200 207 "-" "git/1.7.9.5" 127.0.0.1 - - [20/May/2012:23:04:53 +0200] "GET /git/hello.git/HEAD HTTP/1.1" 200 232 "-" "git/1.7.9.5" 127.0.0.1 - - [20/May/2012:23:04:53 +0200] "PROPFIND /git/hello.git/ HTTP/1.1" 405 563 "-" "git/1.7.9.5" What am I doing wrong? Is it an issue with the version of git and/or apache that I am using perhaps? BTW: I have read all the git http related questions on ServerFault and StackOverflow, and none of them provided me with a solution, so please don't mark this as duplicate.

• First Request to IIS Express Fails with 503 Service Unavailable, Second Succeeds

  - by Chris Moschini

  Each time I start my ASP.Net MVC 3 app from Visual Studio 2010, IIS Express launches and IE spins waiting. The request fails with HTTP 503 Service Unavailable. I hit Refresh in IE, and the request succeeds. All subsequent requests succeed until I stop debugging. The next time I go to start debugging, the first request fails again. Has anyone else experienced this? In IISExpress\applicationhost.config I have: <site name="ProjectName" id="6"> <application path="/" applicationPool="Clr4IntegratedAppPool"> <virtualDirectory path="/" physicalPath="c:\users\chris\dropbox\code\2010\SolutionName\ProjectName" /> </application> <bindings> <binding protocol="http" bindingInformation="*:80:laptop" /> </bindings> </site> I have this in my hosts file: 127.0.0.1 laptop And my Project is set to start with IIS Express, with Project Url set to: http://laptop It's very strange that only the first request fails, perhaps as though Visual Studio isn't waiting long enough for IIS Express to start? Is there some way to make it wait? Stopping debugging, making a change, and then starting again is one of the most common tasks I do so adding another step to get there is pretty annoying.

• HTTP Error 503 - Service is unavailable (how fix?)

  - by SilverLight

  i have a web site for download mobile files and there many users in my web site. sometimes i have the error below : HTTP Error 503 - Service is unavailable 1-so why this error happens and what is that mean? 2-as i know appache free up itself when it's oveloaded, but what about iis? how can i put some limitations in my server (i have remote access to my server) for prevent this error happening? a.is limitation of dowload's speed efficient for prevent that error's occur? how can i do that? is squid useful for this job or i can do that with another iis extension. b.is limitation of download's Bandwidth efficient for prevent that error's occur? how can i do that (with iis or another extension)? in right side of iis - configure area - i found some limits. what do those limits mean and can i use them for keep my server alive all the time? EDIT: after viewing event viewer of windows - custom views - server rols - web server (iis) i figure out there is no error in that area. but many warnings and information. the latest warnings and information are like below : warning A worker process '2408' serving application pool 'ASP.NET 4.0 (Integrated)' failed to stop a listener channel for protocol 'http' in the allotted time. The data field contains the error number. warning A process serving application pool 'ASP.NET 4.0 (Integrated)' exceeded time limits during shut down. The process id was '6764'. warning A worker process '3232' serving application pool 'ASP.NET 4.0 (Integrated)' failed to stop a listener channel for protocol 'http' in the allotted time. The data field contains the error number. warning A process serving application pool 'ASP.NET 4.0 (Integrated)' exceeded time limits during shut down. The process id was '3928'. thanks in advance best regards
