Many places around were re-inventing logException with varying level of success.
In addition, the full error is now printed as a diagnostic instead of debug.
This is more in line with the description of `LogLevel.diagnostic`
("Extended user information (e.g. for more detailed error information)"),
as opposed to the one of `LogLevel.debug_`
("Developer information useful for algorithm debugging").
Since DMD v2.079.0 it is possible to put default, always-used default parameters
after variadic arguments (as long as IFTI is used).
This way we can move all the compile-time arguments, which would always trigger
a template instantiation, to runtime arguments, and re-enable module and function.
The code as is never checks the requested address family when doing a DNS query,
so resolving an IPv6 only host with AddressFamily.INET would still return an IPv6.
This was not working at all since the release of vibe-core due to dependencies on other parts of vibe.d. The unit test has now been moved out of the template class, so that it is actually run.
1. Removes the marker task used by schedule() and instead limits the number of task resumptions to the initial length of the task queue
2. Assigns a static and a dynamic priority to each task. The dynamic priority starts with the same value as the static priority and gets incremented by the static priority each time the task gets overtaken by a higher priority task, eventually leading to the task becoming the highest priority (unless the static priority is zero). Tasks with a higher dynamic priority generally take precedence, unless the concurrency exceeds 10 scheduled tasks, in which case the front of the queue is scheduled in normal FIFO order.
Uninitialized YieldLock values can happen in various ways, dispite the default constructor being disabled. If any such value got destroyed, it would lead to a negative lock count. Since this is handled properly now, the default constructor is also enabled in this commit.
- Deprecates Format.decodeSegment (returning a range of GemericPath.Segment) and added decodeSingleSegment instead, which returns a string instead.
- Adds Format.encodeSegment to encode a single path segment
