• Where are the static methods in gcc's dump file.c.135r.jump

  - by Customizer

  When I run gcc with the parameter -fdump-rtl-jump, I get a dump file with the name file.c.135r.jump, where I can read some information about the intermediate representation of the methods in my C or C++ file. I just recently discovered, that the static methods of a project are missing in this dump file. Do you know, why they are missing in that representation and if there is a possibility to include the static methods in this file, too. Update (some additional information): The test program, I'm using here, is the Hybrid OpenMP MPI Benchmark. Update2: I just reproduced the problem with a serial application, so it has nothing to do with parallel sections.

• How to get extension methods on Roslyn?

  - by eestein

  I need to list all extension methods found on the file. This is what I'm doing so far (looks like it's working): var methods = nodes.OfType<MethodDeclarationSyntax>(); var extensionMethods = methods.Where(m => m.Modifiers.Any(t => t.Kind == SyntaxKind.StaticKeyword) && m.ParameterList.Parameters.Any(p => p.Modifiers.Any(pm => pm.Kind == SyntaxKind.ThisKeyword))); Even though I couldn't test all cases it looks like this is working. But I was wondering if there was a more concise way to approach this solution. Is there some sort of IsExtension or some SyntaxKind.ExtensionMethod? I took a look but could not find anything obvious, at least. I'm using the latest Roslyn Sept/12

• Max number of web methods?

  - by Rippo

  Guys I have a web service in asp.net 2.0 that has 234 methods. It seems that when I add another method the site does not compile in VS2005 until I remove one first. I get a message saying that the new method I just added does not exist in a file that belongs in the Microsoft.Net/.../Temporary Files directory. I have restarted IIS, closed down VS2005, removed all files from this temp directory but to no avail. The only way to get the code to compile is to remove another one so as to keep 234 methods.... I can consistency replicate this behaviour so it cannot be my code. Now I know this seems strange but it is true! One other strange thing is that exactly 100 of the method names begin with the word GetXXXyyyZZZ Has anyone else experienced problems with the maximum number of methods that are allowed in a web service? Many Thanks

• using different key for to_json :methods

  - by fphilipe

  When using :methods in to_json, is there a way to rename the key? I'm trying to replace the real id with a base62 version of it and I want that the value of base62_id has the key id. @obj.to_json( :except => :id :methods => :base62_id ) I tried to do @obj.to_json( :except => :id :methods => { :id => :base62_id } ) but that didn't work. Any advice?

• Searching for empty methods

  - by Brian McCord

  I am currently working on a security audit/code review of our system. This requires me to check all pages in the system and make sure that the code behind contains two methods that are used to check security. Sometimes the code in these methods get commented out to make testing easier. So, my question is does anyone know an easy way to search code, make sure the methods are present, and to determine which ones have no code or have all the code commented out. It would make my job much easier if I can get a list instead of having to look at every file... I'm sure I could write this myself, but I thought someone may know of something that already exists. Thanks!

• Best way to test instance methods without running __init__

  - by KenFar

  I've got a simple class that gets most of its arguments via init, which also runs a variety of private methods that do most of the work. Output is available either through access to object variables or public methods. Here's the problem - I'd like my unittest framework to directly call the private methods called by init with different data - without going through init. What's the best way to do this? So far, I've been refactoring these classes so that init does less and data is passed in separately. This makes testing easy, but I think the usability of the class suffers a little. EDIT: Example solution based on Ignacio's answer: import types class C(object): def __init__(self, number): new_number = self._foo(number) self._bar(new_number) def _foo(self, number): return number * 2 def _bar(self, number): print number * 10 #--- normal execution - should print 160: ------- MyC = C(8) #--- testing execution - should print 80 -------- MyC = object.__new__(C) MyC._bar(8)

• C++ STL containers

  - by cambr

  Different STL containers like vector, stack, set, queue, etc support different access methods on them. If you are coding for example in Notepad++ or vim, you have to continuously refer to the documentation to see what all methods are available, atleast I have to. Is there some good way of remembering which container supports which methods??

• Securing input of private / protected methods?

  - by ts

  Hello, normally, all sane developers are trying to secure input of all public methods (casting to proper types, validating, sanitizing etc.) My question is: are you in your code validating also parameters passed to protected / private methods? In my opinion it is not necessary, if you securize properly parameters of public methods and return values from outside (other classes, db, user input etc...). But I am constantly facing frameworks and apps (ie. prestashop to name one) where validation is often repeated in method call, in method body and once again for securize returned value - which, I think, is creating performace overhead and is also a sign of bad design.

• Linked lists in Java - Help with writing methods

  - by user368241

  Representation of a string in linked lists In every intersection in the list there will be 3 fields : The letter itself. The number of times it appears consecutively. A pointer to the next intersection in the list. The following class CharNode represents a intersection in the list : public class CharNode { private char _data; private int _value; private charNode _next; public CharNode (char c, int val, charNode n) { _data = c; _value = val; _next = n; } public charNode getNext() { return _next; } public void setNext (charNode node) { _next = node; } public int getValue() { return _value; } public void setValue (int v) { value = v; } public char getData() { return _data; } public void setData (char c) { _data = c; } } The class StringList represents the whole list : public class StringList { private charNode _head; public StringList() { _head = null; } public StringList (CharNode node) { _head = node; } } Add methods to the class StringList according to the details : (I will add methods gradually according to my specific questions) (Pay attention, these are methods from the class String and we want to fulfill them by the representation of a string by a list as explained above) Pay attention to all the possible error cases. Write what is the time complexity and space complexity of every method that you wrote. Make sure the methods you wrote are effective. It is NOT allowed to use ready classes of Java. It is NOT allowed to move to string and use string operations. 1) public int indexOf (int ch) - returns the index in the string it is operated on of the first appeareance of the char "ch". If the char "ch" doesn't appear in the string, returns -1. If the value of fromIndex isn't in the range, returns -1. Here is my try : public int indexOf (int ch) { int count = 0; charNode pos = _head; if (pos == null ) { return -1; } for (pos = _head; pos!=null && pos.getData()!=ch; pos = pos.getNext()) { count = count + pos.getValue(); } if (pos==null) return -1; return count; } Time complexity = O(N) Space complexity = O(1) EDIT : I have a problem. I tested it in BlueJ and if the char ch doesn't appear it returns -1 but if it does, it always returns 0 and I don't understand why... I am confused. How can the compiler know that the value is the number of times the letter appears consecutively? Can I assume this because its given on the question or what? If it's true and I can assume this, then my code should be correct right? Ok I just spoke with my instructor and she said it isn't required to write it in the exercise but in order for me to test that it indeed works, I need to open a new class and write a code for making a list so that the the value of every node is the number of times the letter appears consecutively. Can someone please assist me? So I will copy+paste to BlueJ and this way I will be able to test all the methods. Meanwhile I am moving on to the next methods. 2) public int indexOf (int ch, int fromIndex) - returns the index in the string it is operated on of the first appeareance of the char "ch", as the search begins in the index "fromIndex". If the char "ch" doesn't appear in the string, returns -1. If the value of fromIndex doesn't appear in the range, returns -1. Here is my try: public int indexOf (int ch, int fromIndex) { int count = 0, len=0, i; charNode pos = _head; CharNode cur = _head; for (pos = _head; pos!=null; pos = pos.getNext()) { len = len+1; } if (fromIndex<0 || fromIndex>=len) return -1; for (i=0; i<fromIndex; i++) { cur = cur.getNext(); } if (cur == null ) { return -1; } for (cur = _head; cur!=null && cur.getData()!=ch; cur = cur.getNext()) { count = count + cur.getValue(); } if (cur==null) return -1; return count; } Time complexity = O(N) ? Space complexity = O(1) 3) public StringList concat (String str) - returns a string that consists of the string that it is operated on and in its end the string "str" is concatenated. Here is my try : public StringList concat (String str) { String str = ""; charNode pos = _head; if (str == null) return -1; for (pos = _head; pos!=null; pos = pos.getNext()) { str = str + pos.getData(); } str = str + "str"; return str; } Time complexity = O(N) Space complexity = O(1)

• How to generalize a method call in Java (to avoid code duplication)

  - by dln385

  I have a process that needs to call a method and return its value. However, there are several different methods that this process may need to call, depending on the situation. If I could pass the method and its arguments to the process (like in Python), then this would be no problem. However, I don't know of any way to do this in Java. Here's a concrete example. (This example uses Apache ZooKeeper, but you don't need to know anything about ZooKeeper to understand the example.) The ZooKeeper object has several methods that will fail if the network goes down. In this case, I always want to retry the method. To make this easy, I made a "BetterZooKeeper" class that inherits the ZooKeeper class, and all of its methods automatically retry on failure. This is what the code looked like: public class BetterZooKeeper extends ZooKeeper { private void waitForReconnect() { // logic } @Override public Stat exists(String path, Watcher watcher) { while (true) { try { return super.exists(path, watcher); } catch (KeeperException e) { // We will retry. } waitForReconnect(); } } @Override public byte[] getData(String path, boolean watch, Stat stat) { while (true) { try { return super.getData(path, watch, stat); } catch (KeeperException e) { // We will retry. } waitForReconnect(); } } @Override public void delete(String path, int version) { while (true) { try { super.delete(path, version); return; } catch (KeeperException e) { // We will retry. } waitForReconnect(); } } } (In the actual program there is much more logic and many more methods that I took out of the example for simplicity.) We can see that I'm using the same retry logic, but the arguments, method call, and return type are all different for each of the methods. Here's what I did to eliminate the duplication of code: public class BetterZooKeeper extends ZooKeeper { private void waitForReconnect() { // logic } @Override public Stat exists(final String path, final Watcher watcher) { return new RetryableZooKeeperAction<Stat>() { @Override public Stat action() { return BetterZooKeeper.super.exists(path, watcher); } }.run(); } @Override public byte[] getData(final String path, final boolean watch, final Stat stat) { return new RetryableZooKeeperAction<byte[]>() { @Override public byte[] action() { return BetterZooKeeper.super.getData(path, watch, stat); } }.run(); } @Override public void delete(final String path, final int version) { new RetryableZooKeeperAction<Object>() { @Override public Object action() { BetterZooKeeper.super.delete(path, version); return null; } }.run(); return; } private abstract class RetryableZooKeeperAction<T> { public abstract T action(); public final T run() { while (true) { try { return action(); } catch (KeeperException e) { // We will retry. } waitForReconnect(); } } } } The RetryableZooKeeperAction is parameterized with the return type of the function. The run() method holds the retry logic, and the action() method is a placeholder for whichever ZooKeeper method needs to be run. Each of the public methods of BetterZooKeeper instantiates an anonymous inner class that is a subclass of the RetryableZooKeeperAction inner class, and it overrides the action() method. The local variables are (strangely enough) implicitly passed to the action() method, which is possible because they are final. In the end, this approach does work and it does eliminate the duplication of the retry logic. However, it has two major drawbacks: (1) it creates a new object every time a method is called, and (2) it's ugly and hardly readable. Also I had to workaround the 'delete' method which has a void return value. So, here is my question: is there a better way to do this in Java? This can't be a totally uncommon task, and other languages (like Python) make it easier by allowing methods to be passed. I suspect there might be a way to do this through reflection, but I haven't been able to wrap my head around it.

• Two methods with different signatures, jquery is not calling correct method

  - by Lee

  There are two methods GetUserAssignedSystems() and GetUserAssignedSystems(string Id) These methods act very differently from each other. The problem is, when I want to call GetUserAssignedSystems(string Id), the parameter-less method is called. Here are the methods: [WebMethod] [ScriptMethod] public IEnumerable GetUserAssignedSystems(string cacId) { return Data.UserManager.GetUserAssingedSystems(cacId); } [WebMethod] [ScriptMethod] public IEnumerable GetUserAssignedSystems() { //do something else } Here is the jquery making the call: CallMfttService("ServiceLayer/UserManager.asmx/GetUserAssignedSystems", "{'cacId':'" + $('#EditUserCacId').val() + "'}", function(result) { for (var userSystem in result.d) { $('input[UserSystemID=' + result.d[userSystem] + ']').attr('checked', 'true'); } }); Any ideas why this method is being ignored?

• How do I fix my VM's network connection if it seems to be running ok from the host?

  - by AndreiC

  I have a virtual machine (made with vmware) with a linux ubuntu os installed on it (i have a series of them), with NAT network connection - i am running vmware on Windows XP (my host system); the virtual machine can't connect to the internet. All the vmware services seem to be working fine from windows point of view, but inside the machine i can't connect to the internet. What is strange is that the virtual machine was able to use the internet some time ago, but all of a sudden, i just can't use my internet on the virtual machine - i have made no changes to the settings, nor in windows, nor in the virtual machine - so i don't understand.

• Adding code to the beginning / end of methods in runtime dynamically

  - by Irchi

  I know instrumentation is a technique to add trace code dynamically into the methods to enable tracing and debugging. I was wondering if this is only a "Trace" option, hard coded into the CLR to add only trace code, or is there the ability to add any code to the methods? For example, I want to check for a condition in the beginning of every single method call in a certain class (say for permissions). Can I do this via adding dynamic code to the beginning of the methods in execution time? I'm not sure how this trace "instrumentation" thing works, but I'm wondering if this can be used for other goals too, or not.

• accessing my public methods from within my namespace

  - by Derek Adair

  I am in the process of making my own namespace in JavaScript... (function(window){ (function(){ var myNamespace = { somePublicMethod: function(){ }, anotherPublicMethod: function(){ } } return (window.myNamespace = window.my = myNamespace) }()); })(window); I'm new to these kinds of advanced JavaScript techniques and i'm trying to figure out the best way to call public methods from within my namespace. It appears that within my public methods this is being set to myNamespace. Should I call public methods like... AnotherPublicMethod: function(){ this.somePublicMethod() } or... AnotherPublicMethod: function(){ my.somePublicMethod(); } is there any difference?

• How to inherit methods from a parent class in C++

  - by Pat

  When inheriting classes in C++ I understand members are inherited. But how does one inherit the methods as well? For example, in the below code, I'd like the method "getValues" to be accessible not through just CPoly, but also by any class that inherits it. So one can call "getValues" on CRect directly. class CPoly { private: int width, height; public: void getValues (int* a, int* b) { *a=width; *b=height;} }; class CRect: public CPoly { public: int area () { return (width * height); } }; In other words, is there any way to inherit methods for simple generic methods like getters and setters?

  I have a static class with a few methods that just take in a byte array, parses it, and returns a structure. I need to call these methods from many separate threads. Do I need a lock() or some kind of thread-safety within the methods? I can't get my head around it.

• number of methods in an interface.

  - by Jeow

  I know this might seem a controversial question but it really is not meant to be. is there an optimal number of methods in an interface. For example, I personally hate an interface with 20 methods. It is just difficult to implement. The contract seems to hard to maintain. Similarly if the number of methods is just 1. It makes me wonder if it is really a good abstraction. Any thoughts ?

• Can't make virtual host working

  - by sica07

  I have to create a virtual host on a server which, previously hosted a single website (domain name). Now I'm trying to add a second domain on this server (using the same nameserver). What I've done so far: Initially there was no virtual host so I've made one for the second domain: NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot /var/www/bla ServerName www.blabla.com ServerAlias blabla.com <Directory /var/www/blabla> Order deny,allow Allow from all AllowOverride All </Directory> </VirtualHost *:80> Because nothing happend, I changed the DocumentRoot of the apache server to /var/www (initially was the root document of the first website -/var/www/html) and created a virtual host for the first domain too: <VirtualHost *:80> DocumentRoot /var/www/html ServerName www.first.com ServerAlias first.com <Directory /var/www/html> Order deny,allow Allow from all AllowOverride All </Directory> </VirtualHost *:80> In this case, first.com is working ok, but bla.com not. When I ping blabla.com I get the "unkown host" response. What am I doing wrong? Do I have to modify something in the DNS settings too? Thank you.

• Apache Virtual host not recognized

  - by Bozho

  I've been using one server, then I reinstalled everything on another server, and the mod_jk stopped working. Here is the situation: apache 2.0 sitting "in front" mod_jk used to connect to the apache to tomcat tomcat 6.0.26 used to server the actual requests I followed this tutorial. The result is: accessing http://mysite.com opens the index.html in /var/www/ accessing http://mysite.com:8080/ works OK the logs at /var/logs/apache2 show everything is OK: [Mon Mar 29 22:01:53.310 2010] [28349:3075389184] [info] init_jk::mod_jk.c (2830): mod_jk/1.2.26 initialized [Mon Mar 29 22:01:53 2010] [warn] No JkShmFile defined in httpd.conf. Using default /var/log/apache2/jk-runtime-status [Mon Mar 29 22:01:53 2010] [notice] Apache/2.2.9 (Debian) mod_jk/1.2.26 configured -- resuming normal operations I compared the server.xml, jk.conf, sites-enabled/mysite from the new server to those from the old one and they are identical. The domain name is the same (I updated the DNS record today, and it has refreshed successfully) So the question is, what can go wrong? Is there another place where problems would be logged, if such occur? Update What I can be almost certain of is that the virtual host is not recognized. It is always forwarded to the default virtual host. So, how to make sure the virtual host is recognized and working?

• Exim 4 Virtual Domains and Catchall on Debian (Squeeze)

  - by parazuce

  Hello, I've been at it for about 4 hours now. Searching as well as trying different tutorials. Here's my setup: I have 2 domains, both under my own DNS server (MX records setup as well). I have exim4 successfully running, and it is able to send messages from both of those domains. I have tested this using sendmail, and manually setting the "From" attribute. Exim successfully delivers mail to users no matter which domain was specified. I'm fine with that, but I'm having an issue editing virtual domains, and adding custom delivery options (such as a catch all). I've been searching for about 4 hours, and I can't find any up-to-date documentation on how to do this. The old methods would be to add a line such as: domainlist local_domains = @:localhost:dsearch;/etc/exim4/virtual Once that line was added, I made a directory at /etc/exim4/virtual, then created files inside such as example.com which would then contain rules for delivery under that domain. This did not work, however. Searching further, I've found that exim no longer supports dsearch (I guess because they claim it never has?) This is where I'm stuck. I'm on a "split" configuration as well.

• apache2 defaultsite redirect but not virtual host

  - by MMM

  I'm trying to set up a new server with several virtual hosts but also such that if the requested fqdn doesn't match a virtual host then the request is redirected to http://example.com/log.php?url=fqdn I have got the default host redirecting as desired however the virtual host that I have defined doesn't work. I'm testing using a different host and curl -I http://hostname.example.com:8080/ on the command line to read the html headers to check for the redirect header directly rather than following it with a browser (to avoid any caching issues). I have defined a virtualhost as the fqdn of the server but when I use curl to request that virtualhost I get redirected. If I request the server by any other name which doesn't have a virtualhost defined I also get redirected. apache version is 2.2.16 on ubuntu The config (concatenated together in order from a couple of different files) is as follows: Listen 8080 NameVirtualHost * <VirtualHost _default_> ServerAdmin [email protected] RewriteEngine On RewriteRule ^(.*)$ http://example.com/log.php?url=%{HTTP_HOST}$1 [R=302,L] </VirtualHost> <VirtualHost *> <Directory "/var/www"> allow from all Options Indexes </Directory> DocumentRoot /var/www ServerName hostname.example.com </VirtualHost> I've also tried ServerName values of hostname.example.com:* and hostname.example.com:8080 In case I wasn't clear enough: anything.anything.any/something requested from my server should redirect to example.com/log.php?url=anything.anything.any/something foo.example.com (not defined as a VirtualHost) requested from my server should redirect to example.com/log.php?url=foo.example.com hostname.example.com (defined as a VirtualHost) requested from my server should return an html document anothername.example.com (also defined as a VirtualHost) requested from my server should return an html document It turns out that because the servers own fqdn is hostname.example.com that gets redirected to the Default VirtualHost even if there is a named VirtualHost for it. Other fqdn's that are not the same as the servers fqdn work as I intended.

• Canonical Redirect on Dynamic Mass Virtual Hosts on Apache

  - by Josh

  I have a Web app on Apache that allows users to point their domain to the server. Right now I'm using Apache's dynamic mass virtual hosts with an entry VirtualDocumentRoot /www/hosts/%0/docs So with www.companydomain.com it points to /www/hosts/www.companydomain.com/docs The problem is when the user goes to companydomain.com it will point to /www/hosts/companydomain.com/docs Is there an easy way to automatically have Apache check to see if a directory exists for the virtual host, and if not, look for the host name with "www." in front of it? Other subdomains are fine (i.e. abc.domain.com should point to a diff. directory than def.domain.com) but the whole "www" issue is a mystery to me. I am using dynamic mass virtual hosts so the server does not have to restart after each registration for the application. If there is a different way that is fine as long as apache isn't restarted each time. How can I accomplish this? Worst case scenario if there were a way to redirect to a "default" location on the server if not found I could always do a check via PHP or something but I feel like that is a bit hacked together and there has to be a more efficient way. Thanks in advance!

• How to configure multiple virtual hosts for multiple users on Linux/Apache2.2

  - by authentictech

  I want to set up a virtual hosting server on Linux/Apache2.2 that allows multiple users to set up multiple website domains as would be appropriate for commercial shared hosting. I have seen examples (from my then perspective as a shared hosting customer) that allow users to store their web files in their user home directory with directories to correspond to the virtual host domain, e.g.: /home/user1/www/example1.com /home/user2/www/example2.com instead of using /var/www Questions: How would you configure this in your Apache configuration files? (Don't worry about DNS) Is this the best way to manage multiple virtual hosts? Are there others? What safety or security issues do you think I should be aware of in doing this? Many thanks, folks. Edit: If you want to only answer question 1, please feel free, as that is the most urgent to me at this moment and I would consider that an answer to the question. I have done it for myself since posting, but I am not confident that it's the best solution and I would like to know how an experienced sysadmin would do it. Thanks.

• 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.
