The wait group gets passed to HttpServerConnection, then down to the
HttpHandlers. For those handlers that modify the program state, the
wait group is locked so ApiListener will wait on Stop() for the
request to complete. If the request iterates over config objects,
a further check on the state of the wait group is added to abort early
and not delay program shutdown. In that case, 503 responses will be
sent to the client.
Additionally, in HttpServerConnection, no further requests than the
one already started will be allowed once the wait group is joining.
- If there is no package main directory, assume "empty packages".
- Catch exceptions thrown through GlobRecursive() and present a better http 500
to the user.
The packages directory tree is automatically created with the first
package creation, either from the user, or by the `_api` package.
fixes#6129
Removes verboseError from httprequest and uses
HttpUtility::GetLastParameter() instead to find out whether verbose
errors are enabled. Also parsing an invalid URL will now not lead to a
stacktrace anymore.
