Intersystems REGEX engine

#JavaScript #Caché

I am working on a product that uses REGEX and matches it. 
The regex is tested both on the client-side (using the JavaScript REGEX engine) and both on the server-side.

But I couldn't find one word about the way intersystems parses the regex, It is quite elementary to state which which engine it works with. 

from what I could gather from early implementations and such, the engine is based off PCRE, But I need to confirm this somehow, Can anyone give me a definitive answer, Is there any tool to test the regex other than writing it myself??
 

And just to clarify, YES - i found values that would test false in client but test true on server and vice versa, For the exact same regex, So obviously the engine is different..

* My goal is to be able to craft unified regex for both engines to avoid duplicate regex that required maintance...

第三十章 TCP 客户端 服务器通信 - 作业服务器资源

第三十章 TCP 客户端 服务器通信 - 作业服务器资源

作业服务器资源

如果正在编写一个IRIS服务器来与无法控制的客户端连接，则服务器进程必须发出CLOSE命令来关闭TCP连接。就 IRIS而言，CLOSE命令确实会关闭连接，但是在内部TCP/IP会在服务器上为这个连接保留最长两分钟的资源。

当jobserver用于为TCP/IP作业提供服务时，可能会产生意想不到的结果。当一个JOBSERVER进程执行暂停时，该进程立即返回到可用的JOBSERVER进程池，但其资源在内部保留最多两分钟。由于JOBSERVER进程是在第一个可用的基础上分配的，因此来自数量相对较少的客户机的重载可能会耗尽JOBSERVER进程的资源。

From which IRIS version is the new JDBC driver on github?

#InterSystems IRIS

Hello everyone,

I hope you're doing well!

I wanted to share that a new JDBC driver version has been added to the iris-driver-distribution repository on GitHub. The filename is intersystems-jdbc-3.10.1.jar.

However, I noticed that the commit message doesn’t provide much information about the IRIS version this driver is associated with. Could anyone clarify if this is a final release? Is it production-ready? Additionally, are there details about the bugs it addresses or the new features it introduces?

For comparison, the JDBC driver included in the Docker image as of today (23/11/2024) "IMAGE=containers.intersystems.com/intersystems/iris-community:latest-preview" — has the filename intersystems-jdbc-3.10.0.jar, which appears to be an older version.

Looking forward to any insights you can share. Thank you!

Best regards,
Andreas

Can I connect to Epic FHIR sandbox server using iris-fhir-client?

#Autenticación #FHIR #OAuth2 #InterSystems IRIS for Health

I finally figured out how to get JWT token using set x = ##class(%SYS.OAuth2.Authorization).GetAccessTokenClient("medbank","openid fhirUser",.prop,.err).

I also found iris-fhir-client app on Open Exchange. I registered Epic sandbox server, but I cannot list resources. I suspect I need to integrate authorization / authentication. How do I do this with irisfhirclient py?

第二十九章 TCP 客户端 服务器通信 - 记录的拼接

第二十九章 TCP 客户端 服务器通信 - 记录的拼接

记录的拼接

在某些情况下，TCP会将不同的记录连接在一起形成单个记录。如果客户端或服务器进程向一个由WRITE分隔的TCP端口发出一系列WRITE命令，则可能会发生串接！或用于刷新缓冲区的WRITE#命令，而不管读命令是否在连接的另一端等待。
