Avoid the Defer-Disconnect destructor pattern with Boost.Coroutines
2019-09-09 11:41:34 +02:00
Michael Friedrich c5aa978912 Rewrite error handling in HttpServerConnection#EnsureValidHeaders()
Throwing local exceptions unnecessarily pollutes the exception
stack with immediate unwinding. Avoid this pattern at all cost within
Boost.Coroutines. MSVC may handle exceptions differently and cause
problems with stack unwinding.

Michael Friedrich 17d4d17307 Avoid the Defer-Disconnect destructor pattern with Boost.Coroutines
Exceptions in Disconnect() might be thrown (this has been reworked
into error_code locally) which are swallowed inside the Destructor
for being dangerous. On the other hand, swallowing them may
corrupt the stack unwinding operation from the coroutine layer.

The best is to avoid Defer inside lib/remote and call Disconnect()
directly after breaking from other operations.

HttpServerConnection: Prefer error codes over Boost exceptions
2019-09-06 10:22:42 +02:00
Michael Friedrich a208f7baf0 HttpServerConnection: Prefer error codes over Boost exceptions
When run within a coroutine, exceptions on Windows may influence
bad behaviour here. Instead, we'll check for the error code
and extract the message from memory. In contrast to exceptions
which are stored on the stack frame and then return, this costs
a little more memory but simplifies the logic.

This doesn't fix the linked issue, but is related to the analysis.

Michael Friedrich 2760748d78 Fix and improve logging for runtime object sync
config::UpdateObject would create a new object, but this may
have been silently ignored with 'ignore_on_error' - downtimes, etc.
Since we cannot simply fetch the error from inside the config compiler,
we'd just check whether there's a config object created at this stage.
This happens synchronously, and once there is, log something.

The previous code always logged the creation, even if the downtime
was ignored, e.g. when the first master sent one for local host objects.

This commit also adds more details: identity, endpoint, zone to extract
the MessageOrigin details into log messages for better troubleshooting
and debugging.

Michael Friedrich 6cce9c0fdd API: Automatically repair broken packages
This partially reverts #7150 and avoids exceptions
inside the flow. Each time an empty active stage
is detected, Icinga tries to repair it from the
the given directory tree.

Also, the code now takes into account that it should
create the package storage on startup, whether within
the API object, or if disabled, inside the application.

Caching the active stages for packages in memory
only is in effect with the API feature being enabled.
This is useful for other deployed config packages,
not only the internal one.
