* Replacement PR for https://github.com/nim-lang/Nim/pull/23779 that (#23793)c-blake2024-07-071-4/+7
| | | | | | | makes new hash the default, with an opt-out (& js-no-big-int) define. Also update changelog (& fix one typo). Only really expect the chronos hash-order sensitive test to fail until they merge that PR and tag a new release.
* Add Farm Hash conditioned upon `nimPreviewHashFarm` as 64-bit `Hash` (#23735)c-blake2024-06-191-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Unlike present Nim this actually fills `Hash` for `string` & related. For the curious, note that `hashData` remains the aboriginal Nim string hasher & `import hashes {.all.}` allows simultaneous test/time of {orig, murmur, farm} on your favorite CPU & back end compiler. Update tests also conditioned upon `nimPreviewHashFarm` so they should pass either with or without that `define` on. In `--jsbigint=on` mode, only the lower 32-bits of `Hash` match nimvm & run-time values because `type Hash = int` and on JS int=int32, not int64 as for 64-bit Nim platforms. Due to the matching, `const` Table should match run-time `Table` on all platforms. To operate in `--jsbigint=off` mode is feasible but needs much "double precision mul/xor/ror/shr-arithmetic"-style work. That is distracting & also of questionable value since JS added BigInt in 2018, ringabout added Nim support for it in 2021 & `nimPreviewHashFarm` is unlikely to swap from an opt-in to an opt-out default before 2025..2026 which will have given a backward looking time window of 7..8 years for deployment platforms - reasonably generous. Add a changelog entry for 2.2.

| | | | | | | | | | | | | | | | | | | | | (#23102) refs #23091, especially post merge comments Unsure if `experimental` and `bind` are the perfect constructs to use but they seem to get the job done here. Symbol nodes do not get marked `nfOpenSym` if the `bind` statement is used for their symbol, and `nfOpenSym` nodes do not get replaced by new local symbols if the experimental switch is not enabled in the local context (meaning it also works with `push experimental`). However this incurs a warning as the fact that the node is marked `nfOpenSym` means we did not `bind` it, so we might want to do that or turn on the experimental switch if we didn't intend to bind it. The experimental switch name is arbitrary and could be changed. --------- Co-authored-by: Andreas Rumpf <rumpf_a@web.de>

* Fix #22862 - change the httpclient user-agent to be valid spec-wise (#22882)Yardanico2023-10-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Per https://datatracker.ietf.org/doc/html/rfc9110#name-user-agent a User-Agent is defined as follows: ``` User-Agent = product *( RWS ( product / comment ) ) ``` Where ``` product = token ["/" product-version] product-version = token ``` In this case, `token` is defined in RFC 7230 - https://datatracker.ietf.org/doc/html/rfc7230#section-3.2.6: ``` token = 1*tchar tchar = "!" / "#" / "$" / "%" / "&" / "'" / "*" / "+" / "-" / "." / "^" / "_" / "`" / "|" / "~" / DIGIT / ALPHA ; any VCHAR, except delimiters ``` or, in the original RFC 2616 - https://datatracker.ietf.org/doc/html/rfc2616#section-2.2 (next page): ``` token = 1*<any CHAR except CTLs or separators> separators = "(" | ")" | "<" | ">" | "@" | "," | ";" | ":" | "\" | <"> | "/" | "[" | "]" | "?" | "=" | "{" | "}" | SP | HT ``` which means that a `token` cannot have whitespace. Not sure if this should be in the breaking changelog section - theoretically, some clients might've relied on the old Nim user-agent? For some extra info, some other languages seem to have adopted the same hyphen user agent to specify the language + module, e.g.: - https://github.com/python/cpython/blob/main/Lib/urllib/request.py#L1679 (`Python-urllib/<version>`) Fixes #22862.

* copyFile with bufferSize instead of hardcoded value (#22769)Juan Carlos2023-09-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - `copyFile` allows to specify `bufferSize` instead of hardcoded wrong value. Tiny diff. # Performance - 1200% Performance improvement. # Check it yourself Execute: ```bash for i in $(seq 0 10); do bs=$((1024*2**$i)) printf "%7s Kb\t" $bs timeout --foreground -sINT 2 dd bs=$bs if=/dev/zero of=/dev/null 2>&1 | sed -n 's/.* \([0-9.,]* [GM]B\/s\)/\1/p' done ``` (This script can be ported to PowerShell for Windows I guess, it works in Windows MinGW Bash anyways). # Stats - Hardcoded `8192` or `8000` Kb bufferSize gives `5` GB/s. - Setting `262144` Kb bufferSize gives `65` GB/s (script suggestion). --------- Co-authored-by: Andreas Rumpf <rumpf_a@web.de>

* This adds `parseutils.parseSize`, an inverse to `strutils.formatSize` (#21349)c-blake2023-02-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * This adds `parseutils.parseSize`, an inverse to `strutils.formatSize` which has existed since 2017. It is useful for parsing the compiler's own output logs (like SuccessX) or many other scenarios where "human readable" units have been chosen. The doc comment and tests explain accepted syntax in detail. Big units lead to small numbers, often with a fractional part, but we parse into an `int64` since that is what `formatSize` stringifies and this is an inverse over partial function slots. Although metric prefixes z & y for zettabyte & yottabyte are accepted, these will saturate the result at `int64.high` unless the qualified number is a small fraction. This should not be much of a problem until such sizes are common (at which point another overload with the parse result either `float64` or `int128` could be added). Tests avoids `test()` because of a weakly related static: test() failure as mentioned in https://github.com/nim-lang/Nim/pull/21325. This is a more elemental VM failure. As such, it needs its own failure exhibition issue that is a smaller test case. (I am working on that, but unless there is a burning need to `parseSize` at compile-time before run-time it need not hold up this PR.) * This worked with `int` but fails with `int64`. Try for green tests. * Lift 2-result matching into a `checkParseSize` template and format as a table of input & 2 expected outputs which seems nicer and to address https://github.com/nim-lang/Nim/pull/21349#pullrequestreview-1294407679 * Fix (probably) the i386 trouble by using `int64` consistently. * Improve documentation by mentioning saturation. * Improve documentation with `runnableExamples` and a little more detail in the main doc comment based on excellent code review by @juancarlospaco: https://github.com/nim-lang/Nim/pull/21349#pullrequestreview-1294564155 * Address some more @juancarlospaco code review concerns. * Remove a stray space. * Mention milli-bytes in docs to maybe help clarify why wild conventions are so prone to going case-insensitive-metric. * Add some parens.
