TYPO3 Core

My current problem:

Continually enhancing Upgrade mechanism for TYPO3 patch update (m.m.a >> m.m.b) from command line and still running into problems.

Current Upgrade Mechanism

1. replace symbolic link to TYPO3 Source
2. clear PHP OpCache
3. (typo3_console)./typo3cms cache:flush --force

this will result in the followinng:

problem on upgrade 7.6.15 to 7.6.16:
Extension-Manager:

Oops, an error occurred!
Could not analyse class: "TYPO3\CMS\Extensionmanager\ViewHelpers\ReloadSqlDataViewHelper" maybe not loaded or no autoloader? Class TYPO3\CMS\Extensionmanager\ViewHelpers\ReloadSqlDataViewHelper does not exist

This could be fixed by clearing - once more - the PHP OPCache.

Alternative and more brutal methods were tried, among which were some of the following steps:

• rm typotemp
• rm typo3temp/Cache
• use coreapi: cacheapi:clearsystemcache
• or cacheapi:clearallcaches
• use typo3_console without --force: ./typo3cms cache:flush

I ran into problems with TYPO3 6 and TYPO3 7 (didn't try TYPO3 8). With TYPO3 4.5 there were no problems whatsoever - ever.

On Updates a number of about 150 TYPO3 installations were updated. Usually the mechanism worked quite well, but still it is not 100% reliable.

My wishlist

• document recommended way for upgrading from command line on typo3.org
• integrate command line tools (i.e. typo3_console, coreapi into TYPO3 core)
• make command line tools and configuration for TYPO3 a priority

Hints from others

Searches for this topic: the answers where ambiguous: e.g. TYPO3 slack: #cig-deployment:
2 answers on the question:

• "for a 7.6 I suggest to use typo3_console :typo3cms cache:flush --force will do the job"
• "But should be avoided to not step into race conditions. typo3cms cache:flush is usually enough."

Any help is really appreciated.
