  • Way to partialy match a Ruby string using Regexp

    - by Fabiano PS
    I'm working on 2 cases: assume I have those var: a = "hello" b = "hello-SP" b = "not_hello" 1 - Any partial matches I want to accept any string that has the var a inside, so b and c would match. 2 - Patterned match I want to match a string that has a inside, followed by '-', so b would match, c does not. I am having problem, because I always used the syntax /expression/ to define Regexp, so how dinamicaly define an RegExp on Ruby??

  • Sanitize file_get_contents

    - by Luis
    I want to use file_get_contents to implement a proxy so I can do ajax cross domain requests. Querystring will be used to supply the URL to file_get_contents. Now the problem is people can muck around with the qurystring in order to read local files on the server. I dont wnat this. Can someone get me a function to sinitize the querystring in order only to accept urls and not local files: ie: ?url=http://google.com.au - OK ?url=./passwords.txt - Not OK

  • url validation in ruby on rails

    - by jpallavi
    1)Url field should also accept url as “www.abc.com”. If user enters url like this, it should be automatically appended with “http://” resulting in value saved in database as “http://www.abc.com”. If user enters url as “http://www.xyz.com” system should not append “http://”. User should be able to save url with “https://”. what is the code for it in ruby on rails?

  • Simple Ruby Command Line Question

    - by aronchick
    Um - I feel like an idiot, but.... ruby -e '3+5' Outputs nothing (Windows 7, Ruby 1.8.7, Cygwin or Git Bash). What am I missing? Extra credit - will this also allow the extra cool bundle (stolen from TextMate) Execute and Update # = markers to work properly? EDIT Ok that worked, and I'll accept the answer, but e-texteditor still doesn't work with that really cool bundle. Too bad.

  • How do I rename a process on Linux?

    - by jemfinch
    I'm using Python, for what it's worth, but will accept answers in any applicable language. I've tried writing to /proc/$pid/cmdline, but that's a readonly file. I've tried assigning a new string to sys.argv[0], but that has no perceptible impact. Are there any other possibilities? My program is executing processes via os.system (equivalent to system(3)) so a general, *NIX-based solution using an additional spawning process would be fine.

  • Is there a way to get the uid of the other end of a unix socket connection

    - by yuyichao
    Is there a way for a unix socket listener to only accept connection from certain user (chmod/chown does not work for abstract socket afaik), or in another word, get the uid of the incoming connection (on Linux)? Dbus, which uses abstract unix socket on Linux, has a function GetConnectionUnixUser which is used by polkit to determine the caller. So I suppose the dbus-daemon must have a way to do that. Does anyone know how that works? THX

  • Android URLConnection GET query works WiFi but different response 3G

    - by kisplit
    Hey, I have some code which queries a web server using HTTP GET URLConnection connection = new URL("www.example.com" + "?blah=ok").openConnection(); connection.setRequestProperty("Accept-Charset", "UTF-8"); InputStream http_response = connection.getInputStream(); Now when I run this code while connected to WiFi I get the expected response but when I run this with WiFi disabled I instead seem to get the response of www.example.com without the appended query. Does anyone know why this is happening?

  • LaTeX verbatim that can break too long lines?

    - by kotlinski
    I want to generate a PDF of user-submitted text using LaTeX. To handle crazy user input, I first thought about using the verbatim package, but of course it doesn't break up too long lines. Is there some package that works similar to verbatim (i.e., accept any input) but formats the text nicely?

  • WCF Endpoint routing

    - by Dmitriy Sosunov
    Hi, Guys, how to route inbound message between different endpoints. I need to expose the single endpoint that could accept different credentials. I guess, solve this by intercept the incoming message and based on message header then do forward message to appropriate endpoint. Thanks.

  • non blocking TCP-acceptor not reading from socket

    - by Abruzzo Forte e Gentile
    I have the code below implementing a NON-Blocking TCP acceptor. Clients are able to connect without any problem and the writing seems occurring as well, but the acceptor doesn't read anything from the socket and the call to read() blocks indefinitely. Am I using some wrong setting for the acceptor? Kind Regards AFG int main(){ create_programming_socket(); poll_programming_connect(); while(1){ poll_programming_read(); } } int create_programming_socket(){ int cnt = 0; p_listen_socket = socket( AF_INET, SOCK_STREAM, 0 ); if( p_listen_socket < 0 ){ return 1; } int flags = fcntl( p_listen_socket, F_GETFL, 0 ); if( fcntl( p_listen_socket, F_SETFL, flags | O_NONBLOCK ) == -1 ){ return 1; } bzero( (char*)&p_serv_addr, sizeof(p_serv_addr) ); p_serv_addr.sin_family = AF_INET; p_serv_addr.sin_addr.s_addr = INADDR_ANY; p_serv_addr.sin_port = htons( p_port ); if( bind( p_listen_socket, (struct sockaddr*)&p_serv_addr , sizeof(p_serv_addr) ) < 0 ) { return 1; } listen( p_listen_socket, 5 ); return 0; } int poll_programming_connect(){ int retval = 0; static socklen_t p_clilen = sizeof(p_cli_addr); int res = accept( p_listen_socket, (struct sockaddr*)&p_cli_addr, &p_clilen ); if( res > 0 ){ p_conn_socket = res; int flags = fcntl( p_conn_socket, F_GETFL, 0 ); if( fcntl( p_conn_socket, F_SETFL, flags | O_NONBLOCK ) == -1 ){ retval = 1; }else{ p_connected = true; } }else if( res == -1 && ( errno == EWOULDBLOCK || errno == EAGAIN ) ) { //printf( "poll_sock(): accept(c_listen_socket) would block\n"); }else{ retval = 1; } return retval; } int poll_programming_read(){ int retval = 0; bzero( p_buffer, 256 ); int numbytes = read( p_conn_socket, p_buffer, 255 ); if( numbytes > 0 ) { fprintf( stderr, "poll_sock(): read() read %d bytes\n", numbytes ); pkt_struct2_t tx_buf; int fred; int i; } else if( numbytes == -1 && ( errno == EWOULDBLOCK || errno == EAGAIN ) ) { //printf( "poll_sock(): read() would block\n"); } else { close( p_conn_socket ); p_connected = false; retval = 1; } return retval; }

  • What is the fastest XML parser in PHP?

    - by Jakub Lédl
    Hi, for a certain project, I need some way to parse XML and get data from it. So I wonder, which one of built-in parsers is the fastest? Also, it would be nice of the parser could accept a XML string as input - I have my own implementation of thread-safe working with files and I don't want some nasty non-thread-safe libraries to make my efforts useless.
