QUESTION
I'm using Kotlin and vertx. In my vertx app, I'm trying to send a ByteArray to another event consumer.
To do this i'm converting it to a string, and then once its received in the 2nd handler I'm converting it back to a ByteArray but the objects aren't equal. They are very different and I have no idea why.
My 2 event handlers are:
...ANSWER
Answered 2021-Jun-11 at 20:53If you aren't using clustered Vert.x, you can just send and receive ByteArray.
You may need to implement a no-op codec, though: https://alexey-soshin.medium.com/understanding-vert-x-event-bus-c31759757ce8
QUESTION
I'm trying to view files in my workspace, eventually I want to use GetSyncedFiles() to simply view the current state of the files and what revision it is so I can alert the user. But I can't perform the most simple operation with no flags.
The message to the exception is "GetSyncedFiles has no valid options\r\nParameter name: options".
I've tried omitting the file list and setting different flags in the options, always the same result.
...ANSWER
Answered 2021-Jun-07 at 08:53My guess would be that an empty option object is marked as invalid:
If you look at the documentation, the option has many many subclasses that override the default option class https://www.perforce.com/manuals/p4api.net/p4api.net_reference/html/T_Perforce_P4_Options.htm
Have you tried any of those options like this one? Or have you tried just passing null? or omitting the line?
QUESTION
So I have logic handling a queue of print jobs (Which is how all of our other printer integrations are handled) that calls specific functions for each printer (in this case, the sendCommand function) that does the print job, then reports back success / fail so we can properly handle retrying or removing the print job document.
...ANSWER
Answered 2021-May-14 at 02:50You could use closure for this problem.
add a closure parameter to the sendCommand method and remove the Bool return value, hold this parameter as you class property.
QUESTION
Main urls.py file:
...ANSWER
Answered 2021-Apr-27 at 21:02After 4 hours of debugging, I found out that the issue was related to the database being empty.
The webpage that I wanted to render is expecting some models to be passed, and since the DB was empty those models weren't passed and hence the crash. In normal circumstances ( ./manage.py runserver) if DEBUG=True it will tell you what is wrong, but for some reason StaticLiveServerTestCase doesn't have this option or at least I am not aware of it. If anyone knows how to enable some debugger for the StaticLiveServerTestCase please feel free to add to this thread.
So what I did:
./manage.py dumpdata order.tax > data.json - I dumped the data that I needed into a json file and at the beginning of the TestCase I added that data into the fixture
Hope this helps someone with the same issue!
QUESTION
We are trying to implement CSP in our application. But we are stuck for the following situation:
We are using the Epson EPOS SDK script, which connects to the local IP of the printer of our users. That IP is different (of course) for every user, and we can't add all hosts in the connect-src line.
I have tried to generate a hash of the specific code but I can't get that code. The SDK (which is loaded as 'epos.js') is sending an POST with the commands to the printer. When I send that command in PostMan I only get an response (XML) from the printer and not the script.
Now I'm looking for other ways to use CSP in combination with this SDK. Of course I can add an * as connect-src but that will be the same as not using CSP. Is there a way to accept connections to local IP addresses? Or are there better ways to implement this?
ANSWER
Answered 2021-Apr-08 at 04:40The connect-src directive does not support hash-sources, it's road to nowhere.
CSP level 3 does not allow to use IPv4address (except 127.0.0.1) as host-sourses, although browsers support them (Chrome and Firefox was tested). Therefore, it is incorrect to use this feature in production.
The only way is connect-src *;, i do not see any workarounds.

QUESTION
After searching for 2-3 days and trying different solutions, I do not know what the problem is. The picture is loaded and everything is fine, but in realtime it does not want to be saved in any way, I'm already confused where to form with getDownloadUrl, because both the call to ref and the call to task / uploadtask must return the correct value. I already even removed all the progress reader code in UploadImage and now there is code from firebase documentation.

ANSWER
Answered 2021-Feb-07 at 00:47thanks for the tips. decided as follows. I wanted to save the uri by clicking a button in the user's information, but this caused an error, since the user can not always put a picture, and sometimes the uri returns null because the file does not have time to load and the link is not formed in time. And then I remembered that loading a picture is called already at the click of a button and I just wrote down a link to a picture in the photo upload block. Well, in short, here, even tightened
QUESTION
I have this loop over the file msp.chr1
ANSWER
Answered 2020-Oct-22 at 12:44You can generate the name of the file with paste, and then get the file by its name with get. A better option would be to create these files within a list, then you'd only use the j like df=list[[j]].
