php - Is it possible not to load the bootstrapping mechanism at every call? -

-

this not php question, expertise php frameworks.

a lot of frameworks have bootstrapping (loading of classes , files) mechanism. (drupal, zend framework name few)

everytime make request, complete bootloading process needs repeated. , can optimized using apc automatically caching intermediate code

the general question is:

for language, there way not load complete bootstrapping process? there way of "caching" state (or starting at) @ end of bootstraping process not load again? (maybe answer in other language/framework/pattern)

it looks me extremely inefficient.

in general, it's quite possible perform bootstrap / init code once per process, instead of having reload every request. in specific case, don't think possible php (but knowledge of php limited). know have seen criticism of php's architecture... fair php, it's not language or framework things way. go detail...

the style of "run every request" came "cgi" scripts (c.f. common gateway interface), programs got executed separate process webserver whenever request came in matching file, , predefined environmental variables set providing meta information. file executable, written in language. since first way came of doing server-side scripting, number of first languages integrate webserver used cgi interface, perl , php among them.

to eliminate inefficiency identified, second method devised, used plugins webserver itself... apache, includes mod_perl perl, , mod_python python (the latter replaced mod_wsgi python). using these plugins, configure server identify program load once per process, requisite initialization, loads it's persistent state memory, , offers single function server call whenever there request. can lead extremely fast frameworks, things such easy database connection pooling.

the other solution devised write web server (usually stripped down) in language required, , use real webserver act proxy complicated requests, while still serving static files directly. route used python (quite via server provided 'paste' project). it's used java, through tomcat webserver. these servers, in turn, offer approximately same interface mentioned in last paragraph.

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...
