RE: Connection is broken, cannot receive request reply

[Allan Udy via 4D_Tech]

Hi David,

We've seen something similar in recent weeks.

Merged Server database running under Windows 2012 Server, problem seen 
with both 4D v16R3 and v16R4


Periodically, once every 18-36 hours the ten or more 4D Remote clients 
connected to the server lose contact with the server application. IN 
some cases there may be idle issues, but at least half a dozen of the 
users are using the database reasonably heavily on a continual basis 
throughout the day.


If the users quit the 4D Remote and then attempt to connect to the 
server again, they cannot make the connection. It appears that the 4D 
Server is no longer broadcasting its availability.


Interestingly enough the Web Server is still working perfectly well, 
even for brand new connections.


No spike in processes, cpu usage, or anything that even resembles a 
rouge / infinite process.


Only option is to quit the Server app and restart.

Customer is starting to get a bit grumpy about this and we're struggling 
to work out a solution to the problem.   :-(

Alan,

SET DATABASE PARAMETER(54;4)

This is for testing, wanted to make sure 4D closed the connection, not any 
network resource. But alas something is closing it and 4D Remote is crashing 
because of it.

The crash occurs both after a long time of idle, and when the users are 
actively interacting in the application.

The SET DATABASE PARAMETER(14;1) AND SET DATABASE PARAMETER(13;1) seem to have 
made the idle error occur after a longer delay on our test network. But the 
error continues to occur both on our network, and on our client’s network.

We have not solved this problem. We plan to open a tech support case…

Thanks!
David Ringsmuth

Re: HTTP Request PATCH

[Tom Swenson via 4D_Tech]

Yep, I’ve had that “PATCH” working for some time interfacing with a couple of 
REST services.

Hi Doug,

There is no PATCH constant defined in 4D, but you can use “PATCH” as string 
for http method as the first parameter:
HTTP Request(“PATCH”;$url;…)

The other constants are just strings for the other method keywords: GET, 
POST,...

Re: Slow characters visualization

[stardata.info via 4D_Tech]

Someone have solved this issue?

Otherwise is better to work with 4D V15.4 is really slownes to write 
code with this delay.


Thanks

Previously, I only had problems on the Mac with version 15.4 if I had many 
large methods open. Closing everything would solve the problem.

Then I upgraded the Mac from 10.11 to 10.13 High Sierra. Now a single large 
method open is enough to make typing code very frustrating. No problems with 
16.2 on the same computer.

Just wanted to mention it for those that might be considering using 10.13 with 
4D 15. Method editing is not only slow, but startup time and any database 
operation seems perceptively slower. Probably no surprise since 4D 15 is not 
certified to work with 10.13.

Just to confirm, I have also seen the issue on my MacBook Pro since v15 was 
introduced.  It was intermittent, and I have not experienced it for a while. 
Sometimes quitting 4D and restarting would help.  Other times it would restart 
with the problem still present.  I never saw a clear pattern for what would 
trigger the slowness.
