IW 14.2.6 and ISAPI

Posted: Feb 1, 2018 7:28 AM

Hi,

I have updated to IW 14.2.6 from 14.1.8 and now a ISAPI DLL app stops
working after a few minutes(Error 500), I have tested on both Berlin
Update 2 and Tokyo 10.2.2 with same results, reverting back to 14.1.8
makes de app works ok with no problems.

Any hints or setting to set to help identify the change version issue
with my app.

Thanks in advance,

Omar Zelaya

I have been working through some similar issues but I am not sure if they are related to the iw version.

Alex had us put this line in the dpr to turn off some of the new things they were doing in version 14.2. (note you will also need add IWServerControllerBase in the uses section of the dpr.)

begin
TIWServerControllerBase.DisableFixupPatch := True;
IWRun;
end.

If adding that line solves your issue, then you will need to have Alex assist you to find the problem real problem

Hi,

Making the changes to the dpr file has made my app estable now as it was
with previous 14.1.x version.

Now what? how can I find out what the real issue is with 14.2.x and my
ISAPI app?

Thanks in advance,

Omar Zelaya

You might look at this thread for some changes that we made which helped our applications: https://forums.embarcadero.com/thread.jspa?threadID=276948&tstart=0

However, it did not fix all of the issues. We are working with Alex and supplied him with a call stack using Eurekalog:

You might check out the following to see if you maybe supplying this to IW support would help.

One way is to use Eurekalog and their tool call ThreadsSnapShotGui.exe found in the C:\comps\EurekaLog 7\Bin folder

For more information look att: http://eurekalog.blogspot.com/2012/05/what-my-application-is-doing.html

Now what? how can I find out what the real issue is with 14.2.x and my
ISAPI app?

This switch will make it work as before 14.2.x (regarding some multi-thread improvements). We are still investigating it. I suspect that something else (maybe some 3rd party code), or something unusual causes it to fail. I've just sent you an e-mail so we can get more data to find out the cause.

Kind regards
