4063 issue.. wipes out Cumulus.ini

I installed the 4063 file as usual by overwrite of the c:\CumulusMX directory with the .zip content.
On running it, the following appeared in the CMD window:
Cumulus MX v.4.3.0 build 4063
Working Dir: C:\CumulusMX\

and the Cumulus.ini file was set to 'null' (zero bytes).
Restored the Cumulus.ini file from backup, and tried again.. same display.
I've temporarily reverted to my prior version of CUMX 4.2.1 [b4043] - 2024-10-19
Help???

Oh dear, could you send me your Cumulus.ini file from 4.2.1?
All the sensitive stuff should be encrypted, and I will not be able to read those entries, but hopefully it will read enough to reproduce the error. I hope it is not Linux specific!
It sounds like the write operation is running out of buffer space, that will in the INI file code that Steve got from a third party, I'll delve into that to start with...

And of course it works perfectly in my test environment with your file!

I've run out of time this evening; I'll pick this up again tomorrow.
Q: What state was the Cumulus.ini file in after the error? Did it exist? If so, was it zero length, or contain all the content?

After the error, the Cumulus.ini file had zero bytes. Before the error, it was as I'd posted above.

Thanks, v4.3.0 moves some settings to a different section. To do this is reads the ini file, resets the ini file on disk to zero length, then writes it again. The write is the standard write it uses all the time. That is what has failed in your case. The code that does all that has been around for a while which is why this is puzzling.
Some searching shows that the error originates in the OS filesystem with a Windows error 1784. Unfortunately, I cannot find anything helpful in pinning down the cause or fixes. As the write that failed is the same function that MX uses all the time for saving the Cumulus.ini file, maybe it was something transitory on your system.
Perhaps you could have a look in the System event log for that time and see if there is a 1784 error in there, and if that or any surrounding errors give clue?
Have you tried the upgrade multiple times, or just the once?

Hi Mark,
Yes, I'd tried the update multiple times, restoring the prior Cumulus.ini before starting the .exe file.
It failed with the same errors each time. (tried 3 times.. insanity, I guess).
I restored the prior version (and the Cumulus.ini) and it started and ran normally (still running).
I'll dive into the event viewer and see what I can find around the times I tried yesterday...

Arrrgh.. file this in the Journal of Irreproducable Results. Tried this morning.
1) shutdown Old CumulusMX
2) made copy of Cumulus.ini for safety
3) extracted 4063 over existing CumulusMX directory.
4) had event viewer open to diagnose
5) crossed fingers and started 4063
result:
Cumulus MX v.4.3.0 build 4063
Working Dir: C:\CumulusMX\
Cumulus running at:
http://localhost:8998/

Ok, but I don't like not knowing what was going wrong
Is the disk formatted NTFS?

Most of the issues I managed to find around this error are permissions, file locked, corrupt file system, etc etc.
I did wonder if it was a race condition between the file truncation and writing the new content, but they are synchronous operations performed on the same thread.

Since .ini is historically special filetype for windows, I wonder if some antivirus product could be involved in this.
Re: 4063 issue.. wipes out Cumulus.ini

Possibly... The system is using Microsoft Defender Antivirus and Acronis True Image (backup and basic virus protection).
No events were flagged as I'd had the issues by either antivirus products.
Since it started normally yesterday, I'm at a loss to explain what had happened, but 4063 is working fine now.

and the Cumulus.ini file was set to 'null' (zero bytes).
That would scare me.
Restored the Cumulus.ini file from backup.
Good thing that CMX saves the Cumulus.ini in the daily backup as well as at a restart.
Enjoy,
Paul
