php7.4 deprecated syntax notices which cause output before session start

[stAn47]

i just got to check php7.4 and all of my code base and there seems to be some deprecated systax used by core joomla which causes error/notice messages to be shown (when error reporting enabled) which breaks session initalization which further breaks joomla execution.

these are notices before session is initilized

per my understanding of the problem, strings cannot be accessed with $str{1} but require to be accessed via $str[1]

i cannot get further since enabling error reporting breaks joomla and thus i cannot locate more of these now.

i guess J4?

[stAn47]

no, this on the latest j3.9.11
or is php7.4 going to be added only for j4 and later ?

well, i just checked :

https://github.com/joomla/joomla-cms/blob/staging/libraries/vendor/joomla/string/src/phputf8/ord.php
vs
https://github.com/joomla-framework/string/blob/master/src/phputf8/ord.php

and it seems that the issue is fixed on "joomla framework" but not within the latest j3 version.

is there any reason for this ?

best regards, stan

thanks for Info. Please provide always System Informations.

libraries/joomla/database/driver.php needs a patch similar to joomla-framework/database@486f073 (which I needed because the Framework apps that power parts of joomla.org were failing their test suites on 7.4).

A new release of the joomla/string package is needed then a composer update joomla/string is needed for the CMS.

The PHAR wrapper is not PHP 7.4 ready yet, TYPO3/phar-stream-wrapper#49

[alikon]

please test #25782 for 1st point
still left to do joomla/string ...

[wilsonge]

String package released as version 1.4.3

[richard67]

I will make PR for composer update of string package tonight Central European summer time. If someone else wants to do this earlier then let us know here so we don‘t do double work.

[SharkyKZ]

@richard67 There's already PR open #25601. I'll update it.

[richard67]

@SharkyKZ Thanks for info and PR.

[ghost]

@SharkyKZ can this Issue be closed?

[SharkyKZ]

@franz-wohlkoenig I'd keep this open until Phar Stream Wrapper update is released.

[SharkyKZ]

Test PR #26862 please.
