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
