i know postgresql locks row while doing function because of transaction process. tried trigger function when last row of table unlock. let's take example: function_one() , function_two defined inside pg. my application use function_one() add data or update stuff whatever. when it's done, last row needed unlock , can launch other transaction if want. @ point want postgresql launch function_two() when function_one() done. thanks answer(s). edit : more informations i have tried put trigger on pg catalog did not work because had information needed view , can't trigger data of view. so release lock need 1 of following commands: commit; rollback; so if had code so: function_one(); commit; function_two(); that looking for. issue chaining functions in such way dictate when lock gets released.

how convert function javascript typescript? var toggleswitch = this.toggleswitch || (function () { //code } i know var toggleswtich part can written export class toggleswitch {} , i'm not sure rest of line. if write module, you'll end identical code... module toggleswitch { } modules can extended in typescript. difference compiler know whether module declared or not, saves test. to take example further, here example toggleswitch declared twice, different contents. you'll notice can access contents. can split across multiple files: module toggleswitch { export class { go() { alert('a'); } } } module toggleswitch { export class b { go() { alert('b'); } } } var = new toggleswitch.a(); var b = new toggleswitch.b(); a.go(); b.go();

i'm linking against static library , wonder how 1 should handle stripping of dead code in llvm/clang. can't find documentation hints clang has equivalent of -wl, --gc-section or -dead_strip. i assume dead code elimination performed automatically @ higher optimisation levels, that's case in gcc too, right? yet, gcc provides explicit control of via above mentioned flags. clang not provide or missing something? (the system osx) dead stripping linker feature, not compiler feature. neither gcc nor clang have it, result. that's why had use -wl - you're passing flag linker. mac os x linker uses -dead_strip . can pass flag directly clang invocation , pass through automatically.
