Allow upgrades when HOME is read-only #195
Description
I originally asked this as a question at Stack Overflow: https://civicrm.stackexchange.com/questions/48137/upgrade-5-66-0-5-66-2-fails-with-permission-error .
I'm using CiviCRM with Wordpress 6.5.3 and MySQL 5.7.44.
I'm attempting to upgrade my CiviCRM from 5.66.0 to 5.66.2. When I get to the DB upgrade stage, when I hit /wp-admin/admin.php?page=CiviCRM&q=civicrm/upgrade&reset=1 -> Upgrade Now -> OK, I just see an empty progress bar and the message [Executed: undefined].
If I switch to the command-line cv (version v0.3.48), and turn on maximum debugging output, I see this:
singersin@s483:~/www/wp$ cv upgrade:db -vvv

I'm assuming this is because I don't have permission to create directories in $HOME (the site's hosting provider doesn't allow it):
$ ls -ld ~
drwxr-x---+ 15 root singersin 4096 Mar 9 2020 /home/singersin
Can I specify a different temporary directory for it to perform its work somehow? Trying HOME=$HOME/private/tmp cv upgrade:db didn't work, it still tried to create .cv/upgrade in the original non-writeable location. This seems to be because PHP in general doesn't allow overriding HOME:
$ HOME=foo BAR=baz php -r '$home=getenv("HOME"); $bar=getenv("BAR"); echo("[$home;$bar]\n");'
[/home/singersin;baz]
CGI binaries will let me override HOME, but cv refuses to run from a CGI binary:
$ HOME=$HOME/private/tmp php81.cgi bin/cv
Content-type: text/html
The application may only be invoked from a command line, got "cgi-fcgi"
I'm also wondering if there's some place I can find the DB update steps and just run them manually, is that an option? How can I find those SQL statements?
