In CPS we would consume an exception in the except branch by stashing it
into a local then remove the exception from Nim environment so as not to
leak it to other code that would be running before the continuation
continues
However since popCurrentException() assumes that the exception always
exist, removing the exception from an except branch will cause a
SIGSEGV to happen. This commit fixes that.

* nimStackTraceOverride: enable stack traces in exceptions
This is a two-step stack trace collection scheme, because re-raised
exceptions will collect multiple stack traces but use them rarely, when
printing info about an uncaught exception, so it makes sense to only do
the cheap stack unwinding all the time and the relatively expensive
debugging information collection on-demand.
`asyncfutures` implements its own `$` proc for printing
`seq[StackTraceEntry]`, so we have to add the debugging info there, just
like we do for the private `$` proc in `system/excpt`.
* cleaned up PR #15284

* Error -> Defect for defects
The distinction between Error and Defect is subjective,
context-dependent and somewhat arbitrary, so when looking at an
exception, it's hard to guess what it is - this happens often when
looking at a `raises` list _without_ opening the corresponding
definition and digging through layers of inheritance.
With the help of a little consistency in naming, it's at least possible
to start disentangling the two error types and the standard lib can set
a good example here.

(#13677)
* rewritten goto based exception handling; much cleaner implementation; fixes #13668
|
| |
|
|
|
| |
* make goto based exceptions available for 'nim cpp'
* optimize seq.add to be comparable to C++'s emplace_back
|
| |
|
|
|
|
|
|
| |
* os:any implementation
* os:asny: omit flock/funlock calls in echoBinSafe
* Disabled default "unhandled expection" reporting for `--os:any` to reduce
code size. Added unhandledExceptionHook instead which can be used to get
a notification from Nim and handle it from the application.

This implements "deterministic" exception handling for Nim based on goto instead of setjmp. This means raising an exception is much cheaper than in C++'s table based implementations. Supports hard realtime systems. Default for --gc:arc and the C target because it's generally a good idea and arc is all about deterministic behavior.
Note: This implies that fatal runtime traps are not catchable anymore! This needs to be documented.

* libbacktrace support
* switch to a generic stack trace overriding mechanism
When "nimStackTraceOverride" is defined, once of the imported modules
can register its own procedure to replace the default stack trace
generation by calling `registerStackTraceOverride(myOwnProc)`.
Tested with `./koch boot -d:release --debugger:native -d:nimStackTraceOverride --import:libbacktrace`
for the compiler itself and `./bin/nim c -r -f --stacktrace:off --debugger:native -d:nimStackTraceOverride --import:libbacktrace foo.nim`
for an external program.
* make the StackTraceOverrideProc {.noinline.}
