The Boehm GC only needs interior pointer checking if pointers in global
variables or on the heap point to the interior of an object rather than
the beginning. If this does not happen, then checking for interior
pointers causes additional overhead, in particular because any objects
whose sizes are an exact multiple of two words gain another two words of
padding, wasting memory.
If checking of interior pointers is still desired, this can be achieved
by setting the environment variable GC_ALL_INTERIOR_POINTERS.
Pointers on the stack will always be treated as potential interior
pointers, as compiler optimizations may advance the only live reference
to a point past the beginning of an object.
* s/exitStatus(...)/exitStatusLikeShell(...)/
* fix#10273 execShellCmd now returns nonzero when child exits with signal
* test case for #10249 and explanation for the bug
* fix test failure
* add tests/nim.cfg
* add unsetControlCHook to remove a Ctrl-C hook after it was set
Adds the inverse proc to setControlCHook in order to lift a Ctrl-C
hook after it has been set.
* remove check for noSignalHandler in system/excpt.nim
* Codegen now ignores object fields of type void
* Fix `$` bug for objects/tuples where it does not add a comma
* fields/fieldPairs iterators now ignore void types
* Use `isEmptyType` instead of checking for `tyVoid` directly
* Add more Date wrappers to jscore
* Times cosmetic changes
- Improved docs
- Code wrapped at 80 chars
- Formatting fixes using nimpretty
- Remove some old deprecated procs
* add `isNamedTuple`; make $(1, 2) be (1, 2) instead of leaking implementation detail (Field0: 1, Field1: 2)
fixes this: #8670 (comment) /cc @alehander42 @Vindaar @mratsim
* Note: isNamedTuple is useful in other places, eg #10010 (comment)
* move isNamedTuple to helpers.nim to avoid exposing new symbol to system.nim
* remove workaround in tests/vm/tissues.nim failing test now that #10218 was makes it work
Darwin has long deprecated the wait union, but their macros still assume
it unless you define _POSIX_C_SOURCE. This trips up C++ compilers.
This commit duplicates the behavior of WEXITSTATUS when _POSIX_C_SOURCE
is defined.
* add custom pragma support for var and let symbols
* updated changelog for custom pragmas on var and let symbols
* add oldast switch for backwards compatibility
According to POSIX, system() shall returns the termination status in the
format specified by waitpid(), which means WEXITSTATUS should be used to
retrieve the exit code portably.
This fixes execShellCmd on Haiku.
* removed from `compiler`:
* lists (deprecated 2 years ago)
* removed from `lib` (all deprecated 3 years ago):
* ssl
* matchers
* httpserver
* removed from `lib/deprecated`:
* unsigned
* actors (and three accompanying tests)
* parseurl
* moved to `lib/deprecated`:
* securehash (the reason for not directly removing - it was deprecated (only) one year ago)
