I have one abstract class and several subclasses. All share one data/id global.
How can I get concrete class name from id (without opening the object)?
What I have so far:
write $p($lg(^DATAGLOBAL(<id>),1),"~",*-1)It does the job, but is there a more official way?
I'm connecting to a remote device using TCP. It has a binary protocol.
set host = ""
set port = ""
set io = $io
set device = "|TCP|7000"
set timeout = 2
open device:(host:port:"M")
use device:(/IOT="RAW")
read string:timeout
use io
zzdump string
The problem is when reading from it, I get a 0A (also known as 10 or \n or linefeed) byte, which terminates the read.
Expected output:
0000: 42 00 7B 0A 11But I get this output:
0000: 42 00 7BHow can I fix that?
Some additional info:
Here's a simple indirection snippet. It fails with <UNDEFINED> error and I'm not sure why.
ClassMethod ind()
{
kill info
set active = 1
set reactive = 2
for i="active","reactive" {
set info(i)= @i
}
zw info
break
}
I'm getting this exception: <UNDEFINED>zind+5^test.Client.1 *active
I have a date in this format: "YYYY-MM-DD HH:MM:SS+HHMM" how can I convert it to UTC?
write $zdth("2018-02-01 00:00:00+0600",3,5)
>64680,0
write $zdt("64680,0",3,5)
>2018-02-01T00:00:00+03:00
As you see, timezone is lost. Docs for $zdth in timeopt (5) state: Specify time in the form "hh:mm:ss+/-hh:mm" (24-hour clock). The time is specified as local time. The following optional suffix may be supplied, but is ignored: a plus (+) or minus (–) suffix followed by the offset of local time from Coordinated Universal Time (UTC)
SetIdentityInsert call controls the ability of the user to specify a value for the IDENTITY property when saving a new object, a value for the IDENTITY column or an explicit ROWID value in an SQL INSERT. If IDENTITY_INSERT is false and the user specifies an explicit IDENTITY or ROWID value when saving a new object or inserting a new ROW then an error condition is reported.
Setting takes effect immediately and lasts for the duration of the process or until SetIdentityInsert is called again.
My question is how can I change this setting system-wide?
I have a business process.
if it has an error it dies, or if a have a catch all/fault handler the execution flow goes there.
However, I want another behavior.
If any error occurs I want the process to "Pause" (and alert me), so I can figure out what went wrong and resume from the last request.
Here's an example of how it could work:
I'm not set on the exact pause/resume mechanic but I hope it makes the general idea of what I want clear enough. Ideas?
How do you populate and update test/initial data for you classes?
CSV tables? Globals export? And how do you update test data?
Here's one way I found useful for small projects.
I want to consume external websocket api, URL looks like this:
wss://site.com/ws/v2/?&token=<token>
Checked with external tool (Simple WebSocket Client) that websocket works and I can consume the data.
In Cache the relevant functionality is offered by %IO.Socket class.
set sock = ##class(%IO.Socket).%New()
set sock.SSLConfig = "MyEmptySSLConfig"
set sock.TranslationTable="UTF8"
do sock.Open("site.com/ws/v2/?&token=<token>","443", 10,.sc)
However I get this error:
ERROR #7109: Timed out after 10 seconds trying to open stream '|TCP|443|42881' [zOpen+41^%IO.Socket.1:IOT] Any ideas on how Cache can consume websocket API are appreciated.
Today in docs I found this example using NULL:
WRITE $LISTVALID($LB(NULL)),!simplified
zzdump $LB(NULL)and NULL can be case-insensitive:
zzdump $LB(null)seems the same as just:
zzdump $LB()But if null variable is defined then list would contain value from variable. Case sensitive in that situation.
Does anyone have any Idea what is this? Is NULL used anywhere besides as a list element?
