Backtraces Logged in Cacti 1.2.x Branch - Gettext Translation

[reubenfarrelly]

Unfortunately I don't know what the trigger is for this backtrace (it has occurred twice today, once at 5am and another after 10am) but this has been logged:

Gentoo Linux x86_64 with php-8.1.1 and cacti git 1.2.x branch.

I have a hunch this is in the breadcrumb code. Booting my lab.

[TheWitness]

@reubenfarrelly this does not appear to be the 1.2.x branch. There is no translation call on lib/functions.php:5426.

[TheWitness]

@reubenfarrelly , can you install this version and let me know if the problem is resolved?

https://github.com/php-gettext/Gettext/releases/tag/v5.6.1

[TheWitness]

@reubenfarrelly, I just updated the 1.2.x branch with the latest. Please test again.

[reubenfarrelly]

So far - around 12 hours after re-updating again - I haven't seen the issue reoccur and haven't seen any regressions. Will continue to monitor for a bit longer but it seems likely this update may have fixed the problem (I see the latest version of php-gettext also adds support for php-8.1).

[TheWitness]

Good. The changelog is updated to include this. When you are satisfied, just close.

Ok I haven't seen that above error appear again. But this was logged this morning which also looks to be gettext related:

Unfortunately, I've had to revert the commit that updated gettext (not php-gettext). This is because it has a 7.2+ limitation that we simply can't apply to the 1.2.x branch at this point. You may need to force the translation code to use one of the other libraries.
