Unfortunately, the symbol resolution of boost::stacktrace is broken on
FreeBSD, therefore fall back to using backtrace_symbols() to print the
stack trace saved by Boost.
Additionally, -D_GNU_SOURCE is required on FreeBSD for the
_Unwind_Backtrace function used by boost::stacktrace.
This makes the format more similar to what the uncaught C++ and SEH
exception handlers write. Previously there was no indication in the
crash log that a SIGABRT happened.
Older versions of MSVC fail to rethrow an unhandled C++ exception (using
`throw;`) in the termination handler (`std::set_terminate`), however
Icinga relies on this behavior in its crash handler
(`Application::ExceptionHandler`).
Maybe this will save the next person who has to look at this code some
time. Please don't blame me for the implementation, I'm just trying to
reconstruct what it does.
The logic for selecting the traces to print stays the same, but there
are fewer nested ifs now. This changes the format of the returned string
a bit by adding a heading for both traces.
By default, DiagnosticInformation uses the stack trace saved when the
exception was thrown, but this mechanism is not in use on Windows.
Gathering a stacktrace in the terminate handler serves as a fallback.
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.
