my compiler ignoring: #pragma data_section(..., "iram_init"); and #pragma code_section(..., ".icode"); where ... function. this causing segmentation errors when run program. suppose because incorrect syntax gcc compiler ? equivalent ? thanks (context: on raspberry pi in raspian) the equivalent are: __attribute__((section(".icode"))) void fct1(int toto) { ... } __attribute__((section("iram_init"))) int fct2(void) { ... } __attribute__((section(".var"))) int myvar; but take care linker script (commonly ".ld" gnu tools): thoses sections have defined , mapped correct memory

this question people lot of experience of swinject swift. i show problematic code, , question @ bottom. there's quite lot of code, sorry that. this myswinjectstoryboard.swift registration: import swinject extension swinjectstoryboard { class func setup () { defaultcontainer.register( stopwatch.self ) { responder in stopwatch( signals: responder.resolve( signalsservice.self )! ) } defaultcontainer.register( signalsservice.self ) { _ in signalsservice() }.inobjectscope( .container ) defaultcontainer.register( imageservice.self ) { responder in imageservice( signals: responder.resolve( signalsservice.self )! , stopwatch: responder.resolve( stopwatch.self )! ) }.inobjectscope( .container ) defaultcontainer.registerforstoryboard( startupviewcontroller.self ) { ...

i have table added boolean column done when column true want prevent unautorized action (delete, update) on row. i wrote trigger: create trigger productstock_beforeupdate before update or delete on table each row execute procedure trig() create or replace function trig() returns trigger $$ begin if tg_op='update' or tg_op='delete' if old.done=true raise exception 'cant that'; return null; end if; end if; return new; end; $$ if autorized transaction wants change data have first disable trigger. this idea should work when try delete row done=false it returns me "0 rows deleted" , not perform delete. any idea wrong trigger? this caused fact update go through need return new record. delete go through, need return old record. quote manual thus, if trigger function wants triggering action succeed without altering row value, new (or value equal thereto)...

my major development framework java spring framework. have write service layers, controller layer, dao layer, repository layer , on. there thousands of tons of layering. think component based development approach become more productive layering. spring calls every java beans component. think there should major difference between component , layer. layer passive component active. component fires events, call life cycle callbacks methods , actively handle task. on other hand layer gives abstraction. fundamental difference between layer , component? concepts of layer , component different, don't replace each other. layer abstraction. abstract business logic database interactions, or http endpoint handlers. layer consists of components. there may multiple components in layer. let's continue concrete examples. have user , group entities in system. have necessary endpoint handlers both, named usercontroller , groupcontroller . these components , form endpoint handle...
