QUESTION
I have some syntax trouble using zend-select,
I get fields and values out of a searchform, I'm using an array which comes out for example like this (everything here ist out of my model):
Because of the fact that the array-parameters (vorname and nachname (mandant will be integer)) are type string, I want to use wildcards in my select, if the fields vorname or/and nachname are filled by the user.
I tried this one to learn how to write it properly, which works:

Zend will just transform that in to a where statement with equalto's

QUESTION
AFAIK, when passing arrays from JS to Emscripten-compiled C/C++ functions, we are essentially putting the array into a JS simulated HEAP(like Module.HEAPU8
), which is shared by JS code and C/C++ code.
This works fine in a single-threaded environment, but how about a multi-threaded environment, like worker threads? Is there some built-in mechanism to guarantee the thread safety for this simulated HEAP?
If not, does it mean we need to call Module._malloc()
& Module._free()
to dynamically manage heap space for each thread? If so, this sounds like a potential performance bottleneck, given the effort for array copy and space allocation/free might compromise the benefit we gain from using worker threads.
ANSWER
Answered 2017-Oct-27 at 00:29Your understanding is correct, but it is currently impossible to share a WebAssembly.Memory
across workers. JavaScript has SharedArrayBuffer
but WebAssembly doesn't yet support the equivalent (and compatible) WebAssembly.Memory
with shared=true
attribute.
Once it is supported you'll be able to postMessage
a WebAssembly.Memory
and use it to instantiate multiple modules with it across workers. You'll also be able to postMessage
the underlying SharedArrayBuffer
, and read / write to and from it using JavaScript, concurrently with WebAssembly.
In all these cases they memory won't be copied. The WebAssembly malloc
/ free
implementation isn't specified, but what you'll get from e.g. Emscripten will be thread safe. It won't use grow_memory
initially (the design currently disallows growing a shared memory), but will rather pre-allocate and make sure that's thread safe for you (like any multi-threaded C implementation does).
QUESTION
first of all, sorry for my english, it's not my main language, and I'm not sure the question is fully understandable.
I need to do some queries after receiving a Map as a @RequestParam of a Rest Web Service.
I'm trying to call the web service with Postman, and here is the full POST request http://localhost:8080/CDRestApi/rest/cd/esibizione/getIdUdFromIstanzaMetadatoByMap/5/map?25=ALAN&26=IANESELLI
This is my WS code:
