On Windows, the termination handler is executed for uncaught C++
exceptions unless a SEH unhandled exception filter is also set. In this
case, this filter has to explicitly chain the default filter to keep
this behavior.
This commit adds a timeout for both establishing new outgoing and incoming
connections. This timeout applies to everything until the connection is in a
state where either JsonRpcConnection or HttpServerConnection takes over.
This partially reverts 68a0079c26686363b6202a8abd2712d2bf96d9f2 and keeps the
fix only for comment and downtime objects for now. For reasoning, please see
the comment in the code.
68a0079c26686363b6202a8abd2712d2bf96d9f2 introduced two problems that are fixed
with this commit:
1. The new truncated/hashed name did not use EscapeName()
2. There was a possible collision of names when creating objects with a full
name of format "[80 characters]...[40 hex digits]" (i.e. the same as the
truncated/hashed variant but short enough that it isn't hashed)
$env:CMAKE_GENERATOR_PLATFORM is only used in configure-dev.ps1 but now
is also required in configure.ps1 to allow the build pipeline to be
upgraded to Visual Studio 2019.
Additionally bump the versions in paths for Boost and OpenSSL.
At numerous places in the code, something like this is performed:
String name = Downtime::AddDowntime(...);
Downtime::Ptr downtime = Downtime::GetByName(name);
However, `downtime` can be a `nullptr` after this as it is possible that
the downtime is deleted in between.
This commit changes the return type of `Downtime::AddDowntime` to return
a Downtime::Ptr instead of the full name of the downtime. `AddDowntime`
performs the very same `GetByName()` operation internally, but handles
the `nullptr` case correctly and throws an exception.
Only two out of three cases were handled properly by the code: host
downtimes referencing a deleted host and service downtimes referencing a
deleted service worked fine. However, if a service downtime references a
deleted host, `Host::GetByName()` returns `nullptr` which isn't
accounted for. Use `Service::GetByNamePair()` instead as this performs a
check for the host being null internally.
`this` could be deleted after `Notification::BeginExecuteNotification`
exited and before `Notification::ExecuteNotificationHelper` finished.
This is fixed by constructing a `Notification::Ptr` and operate on that
one as it is properly reference-counted.
Note that even when passing `nullptr` as target zone to `RelayMessage()`, the
cluster message will still be sent to the parent zone. These incoming messages
will now be rejected by the parent nodes. At the moment, there's no way to only
send within the local zone.
