Has it been fixed? Which release?

February 12, 2020

Thank you for moving the post to General.

About the issue: I have not restarted the application pool during the test but this is repeatable so what I can do is:

Reboot the web server
Open http://10.1.1.110:10080/TEST/test.dll
Call http://10.1.1.110:10080/TEST/myapp.dll

On the step 3, with a clean situation, the error came up and the problem is exactly the same as described above.

Just a small note: After the nodes being purged, the newly created nodes/sessions has no problem at all. The problem happens only during the "first hyperserver init". In this situation the server works perfectly for months but if I reboot the server or simply restart IIS the problem arises.

February 7, 2020

What I'll describe has been tested with version 1.70.1485 but even with the latest 1.90.1519, having same results.

Compiled a very simple demo app displaying just a text message
Configured IIS with just one 'TEST' Application pointing to C:\UniGUI\TEST\
Configured Hyperserver running my app (it has been renamed to test.dll with my demo app as test.exe)
The Hyperserver test.cfg file has only the following modifications

...
[http_transport]
start_port=16384

[hyper_server]
binary_name=test.exe
...

Calling http://10.1.1.110:10080/TEST/test.dll opens my simple demo app without any problem.

That's ok. Proceeding..

Copy the same app with a different name (myapp.exe)
Configuring Hyperserver with the following myapp.cfg

...
[http_transport]
start_port=16784

[hyper_server]
binary_name=myapp.exe
...

Now I will trigger the problem, calling http://10.1.1.110:10080/TEST/myapp.dll

myapp opens BUT my other app test.dll crashes with : Socket Error # 10054 Connection reset by peer.

Here the logs...

As you can see calling myapp.dll triggers a crash on test.dll.

This happens only because they're on the same folder C:\UniGUI\TEST\, If i put myapp on C:\UniGUI\MYAPP\ it has no problems!

Anywhere on the documentation having one dedicated fodler per-app has been specified, moreover the logs are placed per-process in different sub-folders, in other words having 2 dll/exe on the same folder is something that seems supported by design.

Any help?

This bug is happening on Windows, not only with unsupported Wine "hacks". It's very important to be able to use the HyperServer on a subfolder but it still doesn't work. Please give it the importance that it deserve and fix it, please!

January 25, 2019

I have this issue still present on v1.50.0.1484, which release has the fix?

July 10, 2017

I fixed this problem.

How about? Is there a new version?

About our UniGui version, I'm will ask to the developer that is testing UniGUI as soon as possible. We probably bought a license to evaluate the product but I can't confirm that right now.

July 9, 2017

Thanks...

I mean using Apache JMeter as a proxy and recording the session on my UniGUI site (like this https://www.digitalocean.com/community/tutorials/how-to-use-jmeter-to-record-test-scenarios)

I have my load balancers injecting a session cookie to lock the browser to a certain backend server and your Stress Tool does not support cookies them because UniGui does not use them.

For this reason, going through my load balancers is perfectly fine using a browser (that supports cookies), but your stress tool thrown out many errors because the session jumps from one backend server to the other. The only thing that prevent using different backends for the same session is the cookie injected by the load balancer.

So, JMeter supports cookies and I need it as a stress tool.

JMeter can record a session as your stress tool does, but sometimes the session is reset unexpectedly and, looking on the requests, I can guess that the session is being rejected because of the malformed Ajax parameter that has a double-double quote in it:

Hypertext Transfer Protocol

HTML Form URL Encoded: application/x-www-form-urlencoded

Form item: "Ajax" = "1"

Form item: "IsEvent" = "1"

Form item: "Obj" = "O220"

Form item: "Evt" = "select"

Form item: "this" = "O220"

Form item: ""_fp_" = "_S_ID=QZ3bYFScfeFFD6D531"

Form item: "O220" = "0Verboten""

Form item: "_seq_" = "b"

Form item: "_uo_" = "O80"

On the highlighted row there is the _S_ID string but it looks malformed, somehow mixed with the _fp_ variable.

This is the error that, in my opinion, results in a "invalid session" when recording the session with JMeter.

I don't know why the browser does not show errors, probably JMeter is more sensitive...

Can you help me?

July 9, 2017

Please post your issue to bug reports forum.

I can't, probably because I'm new, I have no permission to post there.

ColIndex=1

_fp_=_S_ID=KSbWmuOucCqu6Yw&OCD=%020%02%02%030%031%03

Sorry for replying to this old thread but I'm having issues recording an UniGui session with Apache JMeter.

It looks like the quoted variable is somehow weird, indeed there should be the _S_ID = <session_id> as the previously requests, but it is different, kinda mixed with the _fp_ variable.

Can anybody explain me if this is the normal behavior?

Looking through Wireshark I can see...

Hypertext Transfer Protocol

HTML Form URL Encoded: application/x-www-form-urlencoded

Form item: "Ajax" = "1"

Form item: "IsEvent" = "1"

Form item: "Obj" = "O220"

Form item: "Evt" = "select"

Form item: "this" = "O220"

Form item: ""_fp_" = "_S_ID=QZ3bYFScfeFFD6D531"

Form item: "O220" = "0Verboten""

Form item: "_seq_" = "b"

Form item: "_uo_" = "O80"

Again, I see double quotes where they shouldn't be, this maybe is the reason because JMeter as a proxy thrown me out giving "Invalid Session ID"...
