Problems with Arcanist

[Nullus]

Hi, I recently made a small edit to 0AD, allowing the "wololo" cheat to switch units to an arbitrary player. I wanted to submit this as a patch, so I created a phabricator account and downloaded arcanist. However, when I try to run any arc command, I get the following error:

PHP Deprecated:  Function libxml_disable_entity_loader() is deprecated in /usr/share/arcanist/support/init/init-script.php on line 92

I am using ubuntu 21.10 with arcanist version 0~git20200925 and PHP version 8.0.8. Could anyone give me advice about how to fix this?

@Nullus

1.) open /src/init/lib/PhutilBootloader.php, find line 275 and note the function name.
2.) make backup of /usr/share/arcanist/src/workflow/ArcanistWorkflow.php
3.) find the function definition in ArcanistWorkflow.php from point 1

4.) remove word "final"

I opened the file to that line, but it seemed to be for error logging. It contained this:

throw new Exception(
          "Error while loading file \"{$path}\": {$message}");

 

[Silier]

Could you upload both files mentioned in the exception message?

cd ~/.local && git clone https://github.com/phacility/arcanist.git && alias arc='~/.local/arcanist/bin/arc' && cd $OLDPWD

Fine. Don't forget to save the alias permanently
 

echo "alias arc='~/.local/arcanist/bin/arc'" >> ~/.bashrc
