QUESTION
I have prepare 2 tree view in separate iframe using jstree. The right tree view should control the left tree view. When user click one one the list in right tree view, the respective item folder will open and selected on left tree view. I can make it happen using div in single page. I control the left tree view using instance of left tree view in right jstree div var instance = $('#left').jstree(true);
.
ANSWER
Answered 2021-Jun-16 at 03:07I had used document.getElementById('1').contentWindow.jQuery('#left').jstree(true);
to get instance from iframe with id='1'. In order to listen to right iframe(with id='2') if any menu has been clicked, I used document.getElementById('2').contentWindow.jQuery('#right').on("changed.jstree",function(e,data){})
. I get the instance of left iframe within this function. By using this instance, I has deselect previous selection, select current selection, and open children of selected menu.

I built an app using Django 3.2.3., but when I try to settup my javascript code for the HTML, it doesn't work. I have read this post Django Static Files Development and follow the instructions, but it doesn't resolve my issue.
Also I couldn't find TEMPLATE_CONTEXT_PROCESSORS
, according to this post no TEMPLATE_CONTEXT_PROCESSORS in django, from 1.7 Django and later, TEMPLATE_CONTEXT_PROCESSORS
is the same as TEMPLATE
to config django.core.context_processors.static
but when I paste that code, turns in error saying django.core.context_processors.static
doesn't exist.
I don't have idea why my javascript' script isn't working.
The configurations are the followings

The way you handle static wrong, remove the static dirs in your INSTALLED_APPS out of STATIC_DIRS and set a STATIC_ROOT then collectstatic again.
Add the following as django documentation to your urls.py

Answered 2021-Jun-16 at 01:31If you are using vuetify from vue-cli-plugin-vuetify
(vue add vuetify
), treeshaking and auto component import is enabled by default, by using vuetify-loader
.
If you look into the source code of vue-cli-plugin-vuetify
, it only uses vuetify-loader
if it is present in your package.json
. So removing vuetify-loader
from package.json
should disable this behavior.

QUESTION
I'm currently using Winsock2 to be able to test a connection to multiple local telnet
servers, but if the server connection fails, the default Winsock client takes forever to timeout.
I've seen from other posts that select()
can set a timeout for the connection part, and that setsockopt()
with timeval
can timeout the receiving portion of the code, but I have no idea how to implement either. Pieces of code that I've copy/pasted from other answers always seem to fail for me.
How would I use both of these functions in the default client code? Or, if it isn't possible to use those functions in the default client code, can someone give me some pointers on how to use those functions correctly?
...ANSWER
Answered 2021-Jun-15 at 21:17
select()
can set a timeout for the connection part.
Yes, but only if you put the socket into non-blocking mode before calling connect()
, so that connect()
exits immediately and then the code can use select()
to wait for the socket to report when the connect operation has finished. But the code shown is not doing that.
setsockopt()
withtimeval
can timeout the receiving portion of the code
Yes, though select()
can also be used to timeout a read operation, as well. Simply call select()
first, and then call recv()
only if select()
reports that the socket is readable (has pending data to read).
Try something like this:
QUESTION
In C++20, we got the capability to sleep on atomic variables, waiting for their value to change.
We do so by using the std::atomic::wait
method.
Unfortunately, while wait
has been standardized, wait_for
and wait_until
are not. Meaning that we cannot sleep on an atomic variable with a timeout.
Sleeping on an atomic variable is anyway implemented behind the scenes with WaitOnAddress on Windows and the futex system call on Linux.
Working around the above problem (no way to sleep on an atomic variable with a timeout), I could pass the memory address of an std::atomic
to WaitOnAddress
on Windows and it will (kinda) work with no UB, as the function gets void*
as a parameter, and it's valid to cast std::atomic
to void*
On Linux, it is unclear whether it's ok to mix std::atomic
with futex
. futex
gets either a uint32_t*
or a int32_t*
(depending which manual you read), and casting std::atomic
to u/int*
is UB. On the other hand, the manual says
The uaddr argument points to the futex word. On all platforms, futexes are four-byte integers that must be aligned on a four- byte boundary. The operation to perform on the futex is specified in the futex_op argument; val is a value whose meaning and purpose depends on futex_op.
Hinting that alignas(4) std::atomic
should work, and it doesn't matter which integer type is it is as long as the type has the size of 4 bytes and the alignment of 4.
Also, I have seen many places where this trick of combining atomics and futexes is implemented, including boost and TBB.
So what is the best way to sleep on an atomic variable with a timeout in a non UB way? Do we have to implement our own atomic class with OS primitives to achieve it correctly?
(Solutions like mixing atomics and condition variables exist, but sub-optimal)
...ANSWER
Answered 2021-Jun-15 at 20:48You shouldn't necessarily have to implement a full custom atomic
API, it should actually be safe to simply pull out a pointer to the underlying data from the atomic
and pass it to the system.
Since std::atomic
does not offer some equivalent of native_handle
like other synchronization primitives offer, you're going to be stuck doing some implementation-specific hacks to try to get it to interface with the native API.
For the most part, it's reasonably safe to assume that first member of these types in implementations will be the same as the T
type -- at least for integral values [1]. This is an assurance that will make it possible to extract out this value.
... and casting
std::atomic
tou/int*
is UB
This isn't actually the case.
std::atomic
is guaranteed by the standard to be Standard-Layout Type. One helpful but often esoteric properties of standard layout types is that it is safe to reinterpret_cast
a T
to a value or reference of the first sub-object (e.g. the first member of the std::atomic
).
As long as we can guarantee that the std::atomic
contains only the u/int
as a member (or at least, as its first member), then it's completely safe to extract out the type in this manner:

I need a cloud function that triggers automatically once per day and query in my "users" collection where "watched" field is true and update all of them as false. I get "13:26 error Parsing error: Unexpected token MyFirstRef" this error in my terminal while deploying my function. I am not familiar with js so can anyone please correct function. Thanks.
...ANSWER
Answered 2021-Jun-15 at 16:13There are several points to correct in your code:
- You need to return a Promise when all the asynchronous job is completed. See this doc for more details.
- If you use the
await
keyword, you need to declare the functionasync
, see here. - A
QuerySnapshot
has aforEach()
method - You can get the
DocumentReference
of a doc from theQuerySnapshot
just by using theref
property.
