when multiple apptasks are scheduled, we end up with a sequence like this:
- task1 finishes
- task2 (uninstall) removes appdata directory
- sftp rebuild (from task1 finish)
- task2 fails because sftp rebuild created empty appdata directory
a fix is to delay the sftp rebuild until all tasks are done. of course,
the same race is still there, if a user initiated another task immediately
but this seems unlikely. if that happens often, we can further add a sftpRebuildInProgress
flag inside apptaskmanager.
had to move the ~ login/logout regexp inside. This is because of
https://www.ruby-forum.com/t/proxy-pass-location-inheritance/239135
What it says is that a regexp inside a matching location prefix is
given precedence regardless of how it appears in the file. This means
that the negative regexp got precedence over login|logout and thus
went into infinite redirect. By moving it to same level, the regexps
are considered in order.
Some notes on nginx location:
* First, it will match the prefixes (= and the /). If =, the matching stops.
If /xx then the longest match is "remembered"
* It will then match the regex inside the longest match. First match wins
* It will then match the rest of the regex locations. First match win
* If no regex matched, it will then do the remembered longest prefix

the main reason this is under app and not domain is because it let's
the user know that an app has to be installed for the whole thing to work.
