java - How to force Apache Tomcat not to reuse a thread from the thread pool? -

-

we've got normal-ish server stack including blazeds, tomcat , hibernate.

we'd arrange things such if errors (especially assertionerror) thrown, current thread considered in unknown state , won't used further http requests. (partly because we're storing things, such hibernate transaction session, in thread-local storage. now, can catch throwables , make sure roll transactions , rethrow, there's no guarantee other code may have left knows in thread-local storage.)

tomcat default thread pool behavior reuses threads. tried specifying our own executor, seems specific method of changing thread pool behavior, doesn't call executor.execute() new task each request. (most reuses same execution context requests in same http connection.)

one option disable keepalive, there's 1 request per http connection, that's ugly.

anyway, i'd know. there way tell tomcat not reuse thread, or kill or exit thread tomcat forced create new one?

(from tomcat source, appears tomcat close connection , abandon task/thread after sending http 500 response, don't know how blazeds generate 500 response; that's angle i'd know more about.)

i suggest getting rid of use of thread-local storage, or @ least coming method clear thread-local storage when request first enters pipeline (with <filter> in web.xml, example).

having reconfigure basic tomcat work app points code smell.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

fortran - Function return type mismatch -

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
