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.
* first implementation of the =trace and =dispose hooks for the cycle collector
* a cycle collector for ARC: progress
* manual: the .acyclic pragma is a thing once again
* gcbench: adaptations for --gc:arc
* enable valgrind tests for the strutils tests
* testament: better valgrind support
* ARC refactoring: growable jumpstacks
* ARC cycle detector: non-recursive algorithm
* moved and renamed core/ files back to system/
* refactoring: --gc:arc vs --gc:orc since 'orc' is even more experimental and we want to ship --gc:arc soonish
* conversions to unsigned numbers are not checked anymore; implements / fixes https://github.com/nim-lang/RFCs/issues/175
* change the spec yet again to be less consistent but to make more sense; updated the changelog
https://github.com/nim-lang/Nim/pull/12600
and in
https://forum.nim-lang.org/t/5499
indicates that everyone is happy/happier with ``pop``.
This just renames the brand new ``take``s to ``pop`` and installs inline
aliases/wrappers to preserve ``Table.take`` and ``TableRef.take``.
Update apis.rst to try to maintain consistency of remove-and-return procs.
* Clarifies experimental / parallel on manual.rst
Details:
Calling `useParallel()` in example fails with compiler error
Error: 'parallel' section without 'spawn'
Adding `spawn` causes error:
Error: internal error: (filename: "ccgexprs.nim", line: 1032, column: 17)
No stack traceback available
To create a stacktrace, rerun compilation with ./koch temp c <file>
Therefore a separate proc, `threadedEcho`, is added for the echo'ing
of the string, which allows the example to build, however, `sync()`
must be added so that the "echo in parallel" strings will actually
be shown on the terminal. Otherwise, the program will spawn of the
threads and exit before they can return to the main thread.
* Fixes and clarifies example for threading in manual.rst
Issue:
Calling useParallel() in example failed with compiler error
`Error: 'parallel' section without 'spawn'`
Adding spawn yielded compiler error:
```bash
Error: internal error: (filename: "ccgexprs.nim", line: 1032, column: 17)
No stack traceback available
To create a stacktrace, rerun compilation with ./koch temp c
```
Proposed Solution:
- Separate proc, threadedEcho, is added for the echo'ing
of the string, which allows the example to build
- Added the thread number so that it can demonstrate that sometimes
threads which were started sooner, come back after threads which
were started later.
* Fix many broken links
Note that contrary to what docgen.rst currently says, the ids have
to match exactly or else most web browsers will not jump to the
intended symbol.
* Prefer relative links for Nim documentation
This is more friendly to those browsing the documentation without
a network connection. The nim-doc package in Debian allows this,
for example.
Also, the domain name being used was not consistent. It could have
been either nim-lang.org or nim-lang.github.io, and those reading
the stable docs could have found themselves suddenly reading the
devel docs instead.
* koch.rst: remove link to nonexistent section
* manual.rst: remove unintended link
cast[T](0) is interpreted as a link to id 0 with text T, so escape
the opening parentheses to display the intended output.
* asyncstreams: replace unintended link with emphasis
* Fix word wrapping
