* 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.
* Add neglected API call `find` to heapqueue.
* Add a changelog.md entry, `since` annotation and rename parameter to be
`heap` like all the other procs for consistency.
* Add missing import.
* json custom serialization; application for strtabs
* serialize using nesting
* make toJson more feature complete
* add since
* Revert "Improve JSON serialisation of strtabs (#14549)"
This reverts commit 7cb4ef26ad.
* better approach via mixin
* toJson, jsonTo
* fix test
* address comments
* move to jsonutils
* doc
* cleanups
* also test for js
* also test for vm
Previously, the `net` module use the blanket "ALL" as the default cipher
list. This list may contain security ciphers that are weak and/or outdated
according to the current standard.
This commit introduces a new module `ssl_config` that contains the
latest OpenSSL configurations as recommended by Mozilla OpSec, and
make the `net` module use the cipher list targeting `intermediate`
compatibility level as the default.
Per SSL_get_error(3):
The current thread's error queue must be empty before the TLS/SSL I/O
operation is attempted, or SSL_get_error() will not work reliably.
There has been records of not clearing the error queue causing weird SSL
errors when there shouldn't be any, see:
https://github.com/openssl/openssl/issues/11889
Closing a socket clears the error queue of the entire thread, which
seems to be a bit too invasive.
Also I don't find any reason in the PR that added this.
* Change `UnpackError` with `UnpackDefect`
The deprecation warning for `UnpackError` exception raised by some
`inline` procedures in the Nim standard library propagates to the user
code. If the user code has a requirement for building without warnings
this is a problem for the successful execution of the tests. In order
to resolve this, all occurrences of `UnpackError` in the Nim code base
are changed to `UnpackDefect`. Only the type alias is retained to not
break other people's user code since `UnpackError` is exported type.
* Remove the catching of `UnpackDefect`
Defect exceptions should not be cached, because they indicate problem in
the API usage. The code in `nimblesocket.nim` is rewritten to first
check whether there is a value set into the `knownDomain` variable from
the `Option` type before usage.
