The new mechanism can deal with more complex scenarios such as
not nil field appearing in a non-default case object branch or
a field within a generic object that may depend on a when branch.
The commit also plugs another hole: the user is no longer able
to create illegal default values through seq.setLen(N).
New issue: since `Table[A, B]` allocates its backing storage with
`newSeq[KeyValuePair[A, B]]`, it's no longer legal to create a table
with `not nil` types used as either keys or values.
* code cleanups and feature additions
* added basic test and koch/CI integration
* make it build on Unix
* DrNim: now buildable on Unix, only takes 10 minutes, enjoy
* added basic documentation for DrNim which can also be seen as the RFC we're following
* drnim: change the build setup so that drnim.exe ends up in bin/
* makes simple floating point ranges work
* added basic float range check
* drnim: teach Z3 about Nim's range types plus code refactoring
* drnim: make unsigned numbers work
* added and fixed index checking under setLen
* first implementation of .ensures, .invariant and .assume (.requires still missing and so is proc type compatibility checking
* drnim: .requires checking implemented
* drnim: implemented .ensures properly
* more impressive test involving min()
* drnim: check for proc type compatibility and base method compatibility wrt .requires and .ensures
* testament: support for 'pattern <directory>
* koch: uses new <directory> feature of testament
* drnim: added tiny musings about 'old'
* Make testament work with old SSL versions
* koch: add support for 'koch drnim -d:release'
* drnim: preparations for the param.old notation
* new minor feature: macros for proc types, to be documented
* Finished the implementation and added tests
* [skip ci] Describe the new custom pragmas in the manual and the changelog

* workflows/ci_docs: fix docs publishing
It turns out that github.ref is the full ref name, so we have to be a
bit more specific.
See https://developer.github.com/v3/activity/events/types/#pushevent
Also fixed a silly typo :)
* workflows/ci_docs: run CI when there are changes to the workflow
* Unwind just the "pseudorandom probing" (whole hash-code-keyed variable
stride double hashing) part of recent sets & tables changes (which has
still been causing bugs over a month later (e.g., two days ago
https://github.com/nim-lang/Nim/issues/13794) as well as still having
several "figure this out" implementation question comments in them (see
just diffs of this PR).
This topic has been discussed in many places:
https://github.com/nim-lang/Nim/issues/13393https://github.com/nim-lang/Nim/pull/13418https://github.com/nim-lang/Nim/pull/13440https://github.com/nim-lang/Nim/issues/13794
Alternative/non-mandatory stronger integer hashes (or vice-versa opt-in
identity hashes) are a better solution that is more general (no illusion
of one hard-coded sequence solving all problems) while retaining the
virtues of linear probing such as cache obliviousness and age-less tables
under delete-heavy workloads (still untested after a month of this change).
The only real solution for truly adversarial keys is a hash keyed off of
data unobservable to attackers. That all fits better with a few families
of user-pluggable/define-switchable hashes which can be provided in a
separate PR more about `hashes.nim`.
This PR carefully preserves the better (but still hard coded!) probing
of the `intsets` and other recent fixes like `move` annotations, hash
order invariant tests, `intsets.missingOrExcl` fixing, and the move of
`rightSize` into `hashcommon.nim`.
* Fix `data.len` -> `dataLen` problem.
* #13806 - first call sysctl with a null buffer to get the length, then alloc buffer and call again
* Use csize_t rather than csize
* Suggestions from @Clyybber

* workflows/ci_docs: publish documentation to Github Pages
This should be a complete replacement for our current Travis CI setup.
* workflows/ci_docs: run docgen upon modification to the css on push
So that any changes regarding the stylesheets would be reflected on the
published docs.
* workflows/ci_docs: build the compiler in release mode
* workflows/ci_docs: set branch name for the generated docs
This makes the "Source" links work correctly.
* workflows/ci_docs: run docgen on windows and osx too
Only deploy the Linux-generated version.
* workflows/ci_docs: cache csources compiler
This should cut the time spent building csources, which is about 1-2mins
depending on OS.
* stacktraces can now show custom runtime msgs
* improve tests/stdlib/tstackframes.nim
* fix test for --gc:arc
* test --stacktraceMsgs:on and --stacktraceMsgs:off
* --stacktracemsgs:off by default
* osproc: move fork-based code path under the when conditional
* osproc: avoid using the environ global on Haiku
* osenv: import environ from stdlib.h on Haiku
Haiku's environ is declared in `<stdlib.h>` by default, differing from
POSIX and/or Linux. Import it from there to avoid collision with anyone
importing `<stdlib.h>` from Nim.
* koch boot --gc:arc now passes the nim stage
... but generates invalid C code
* Move it closer to where its used
* Try something else
* Poor mans var
* Use UncheckedArray instead
