nim: Update to 1.4.0

Changelog extracted from https://nim-lang.org/blog/2020/10/16/version-140-released.html

Standard library additions and changes

    Added some enhancements to std/jsonutils module.
        Added a possibility to deserialize JSON arrays directly to
        HashSet and OrderedSet types and respectively to serialize
        those types to JSON arrays via jsonutils.fromJson and
        jsonutils.toJson procedures.
        Added a possibility to deserialize JSON null objects to Nim
        option objects and respectively to serialize Nim option object
        to JSON object if isSome or to JSON null object if isNone via
        jsonutils.fromJson and jsonutils.toJson procedures.
        Added a Joptions parameter to jsonutils.fromJson currently
        containing two boolean options allowExtraKeys and
        allowMissingKeys.
            If allowExtraKeys is true Nim’s object to which the JSON
            is parsed is not required to have a field for every JSON
            key.
            If allowMissingKeys is true Nim’s object to which JSON is
            parsed is allowed to have fields without corresponding
            JSON keys.
    Added bindParams, bindParam to db_sqlite for binding parameters
    into a SqlPrepared statement.
    Added tryInsert,insert procs to db_* libs which accept primary key
    column name.
    Added xmltree.newVerbatimText support create style’s,script’s
    text.
    uri module now implements RFC-2397.
    Added DOM Parser to the dom module for the JavaScript target.
    The default hash for Ordinal has changed to something more
    bit-scrambling. import hashes; proc hash(x: myInt): Hash =
    hashIdentity(x) recovers the old one in an instantiation context
    while -d:nimIntHash1 recovers it globally.
    deques.peekFirst and deques.peekLast now have var Deque[T] -> var T
    overloads.

    File handles created from high-level abstractions in the stdlib
    will no longer be inherited by child processes. In particular,
    these modules are affected: asyncdispatch, asyncnet, system,
    nativesockets, net and selectors.

    For asyncdispatch, asyncnet, net and nativesockets, an inheritable
    flag has been added to all procs that create sockets, allowing the
    user to control whether the resulting socket is inheritable. This
    flag is provided to ease the writing of multi-process servers,
    where sockets inheritance is desired.

    For a transition period, define nimInheritHandles to enable file
    handle inheritance by default. This flag does not affect the
    selectors module due to the differing semantics between operating
    systems.

    asyncdispatch.setInheritable, system.setInheritable and nativesockets.setInheritable are also introduced for setting file handle or socket inheritance. Not all platforms have these procs defined.

    The file descriptors created for internal bookkeeping by
    ioselector_kqueue and ioselector_epoll will no longer be leaked to
    child processes.
    strutils.formatFloat with precision = 0 has been restored to the
    version 1 behaviour that produces a trailing dot,
    e.g. formatFloat(3.14159, precision = 0) is now 3., not 3.

    Added commonPrefixLen to critbits.

    relativePath(rel, abs) and relativePath(abs, rel) used to silently
    give wrong results (see #13222); instead they now use
    getCurrentDir to resolve those cases, and this can now throw in
    edge cases where getCurrentDir throws. relativePath also now works
    for js with -d:nodejs.

    JavaScript and NimScript standard library changes:
    streams.StringStream is now supported in JavaScript, with the
    limitation that any buffer pointers used must be castable to ptr
    string, any incompatible pointer type will not work. The lexbase
    and streams modules used to fail to compile on NimScript due to a
    bug, but this has been fixed.

    The following modules now compile on both JS and NimScript:
    parsecsv, parsecfg, parsesql, xmlparser, htmlparser and
    ropes. Additionally supported for JS is cstrutils.startsWith and
    cstrutils.endsWith, for NimScript: json, parsejson, strtabs and
    unidecode.

    Added streams.readStr and streams.peekStr overloads to accept an
    existing string to modify, which avoids memory allocations,
    similar to streams.readLine (#13857).

    Added high-level asyncnet.sendTo and asyncnet.recvFrom UDP functionality.

    dollars.$ now works for unsigned ints with nim js.

    Improvements to the bitops module, including bitslices,
    non-mutating versions of the original masking functions,
    mask/masked, and varargs support for bitand, bitor, and bitxor.

    sugar.=> and sugar.-> changes: Previously (x, y: int) was
    transformed into (x: auto, y: int), it now becomes (x: int, y:
    int) for consistency with regular proc definitions (although you
    cannot use semicolons).

    Pragmas and using a name are now allowed on the lefthand side of =>.
    Here is an example of these changes:

    import sugar

    foo(x, y: int) {.noSideEffect.} => x + y

    # is transformed into

    proc foo(x: int, y: int): auto {.noSideEffect.} = x + y

    The fields of times.DateTime are now private, and are accessed
    with getters and deprecated setters.

    The times module now handles the default value for DateTime more
    consistently. Most procs raise an assertion error when given an
    uninitialized DateTime, the exceptions are == and $ (which returns
    "Uninitialized DateTime"). The proc times.isInitialized has been
    added which can be used to check if a DateTime has been
    initialized.

    Fix a bug where calling close on io streams in osproc.startProcess was a noop and led to hangs if a process had both reads from stdin and writes (e.g. to stdout).
    The callback that is passed to system.onThreadDestruction must now be .raises: [].

    The callback that is assigned to system.onUnhandledException must now be .gcsafe.

    osproc.execCmdEx now takes an optional input for stdin, workingDir and env parameters.

    Added a ssl_config module containing lists of secure ciphers as recommended by Mozilla OpSec

    net.newContext now defaults to the list of ciphers targeting “Intermediate compatibility” per Mozilla’s recommendation instead of ALL. This change should protect users from the use of weak and 
insecure ciphers while still provides adequate compatibility with the majority of the Internet.

    A new module std/jsonutils with hookable jsonTo,toJson,fromJson operations for json serialization/deserialization of custom types was added.
    A new proc heapqueue.find[T](heap: HeapQueue[T], x: T): int to get index of element x was added.
    Added rstgen.rstToLatex a convenience proc for renderRstToOut and initRstGenerator.
    Added os.normalizeExe.
    macros.newLit now preserves named vs unnamed tuples.
    Added random.gauss, that uses the ratio of uniforms method of sampling from a Gaussian distribution.
    Added typetraits.elementType to get the element type of an iterable.
    typetraits.$ changes: $(int,) is now "(int,)" instead of "(int)"; $tuple[] is now "tuple[]" instead of "tuple"; $((int, float), int) is now "((int, float), int)" instead of "(tuple of (int, 
float), int)"

    Added macros.extractDocCommentsAndRunnables helper.
    strformat.fmt and strformat.& support specifier =. fmt"{expr=}" now expands to fmt"expr={expr}".

    Deprecations: instead of os.existsDir use dirExists, instead of os.existsFile use fileExists.
    Added the jsre module, Regular Expressions for the JavaScript target..
    Made maxLines argument Positive in logging.newRollingFileLogger, because negative values will result in a new file being created for each logged line which doesn’t make sense.
    Changed log in logging to use proper log level for JavaScript, e.g. debug uses console.debug, info uses console.info, warn uses console.warn, etc.
    Tables, HashSets, SharedTables and deques don’t require anymore that the passed initial size must be a power of two - this is done internally. Proc rightSize for Tables and HashSets is 
deprecated, as it is not needed anymore. CountTable.inc takes val: int again not val: Positive; i.e. it can “count down” again.
    Removed deprecated symbols from macros module, some of which were deprecated already in 0.15.
    Removed sugar.distinctBase, deprecated since 0.19. Use typetraits.distinctBase.

    asyncdispatch.PDispatcher.handles is exported so that an external low-level libraries can access it.
    std/with, sugar.dup now support object field assignment expressions:

    import std/with

    type Foo = object
      x, y: int

    var foo = Foo()
    with foo:
      x = 10
      y = 20

    echo foo

    Proc math.round is no longer deprecated. The advice to use strformat instead cannot be applied to every use case. The limitations and the (lack of) reliability of round are well documented.

    Added getprotobyname to winlean. Added getProtoByname to nativesockets which returns a protocol code from the database that matches the protocol name.

    Added missing attributes and methods to dom.Navigator like deviceMemory, onLine, vibrate(), etc.
    Added strutils.indentation and strutils.dedent which enable indented string literals:

    import strutils
    echo dedent """
      This
        is
          cool!
      """

    Added initUri(isIpv6: bool) to uri module, now uri supports parsing ipv6 hostname.

    Added readLines(p: Process) to osproc.
    Added the below toX procs for collections. The usage is similar to procs such as sets.toHashSet and tables.toTable. Previously, it was necessary to create the respective empty collection and add 
items manually.
        critbits.toCritBitTree, which creates a CritBitTree from an openArray of items or an openArray of pairs.
        deques.toDeque, which creates a Deque from an openArray.
        heapqueue.toHeapQueue, which creates a HeapQueue from an openArray.
        intsets.toIntSet, which creates an IntSet from an openArray.

    Added progressInterval argument to asyncftpclient.newAsyncFtpClient to control the interval at which progress callbacks are called.
    Added os.copyFileToDir.

Language changes

    The =destroy hook no longer has to reset its target, as the compiler now automatically inserts wasMoved calls where needed.

    The = hook is now called =copy for clarity. The old name = is still available so there is no need to update your code. This change was backported to 1.2 too so you can use the more readable =copy 
without loss of compatibility.

    In the newruntime it is now allowed to assign to the discriminator field without restrictions as long as the case object doesn’t have a custom destructor. The discriminator value doesn’t have to 
be a constant either. If you have a custom destructor for a case object and you do want to freely assign discriminator fields, it is recommended to refactor the object into 2 objects like this:

    type
      MyObj = object
        case kind: bool
        of true: y: ptr UncheckedArray[float]
        of false: z: seq[int]

    proc `=destroy`(x: MyObj) =
      if x.kind and x.y != nil:
        deallocShared(x.y)

    Refactor into:

    type
      MySubObj = object
        val: ptr UncheckedArray[float]
      MyObj = object
        case kind: bool
        of true: y: MySubObj
        of false: z: seq[int]

    proc `=destroy`(x: MySubObj) =
      if x.val != nil:
        deallocShared(x.val)

    getImpl on enum type symbols now returns field syms instead of idents. This helps with writing typed macros. The old behavior for backwards compatibility can be restored with --useVersion:1.0.
    The typed AST for proc headers will now have the arguments be syms instead of idents. This helps with writing typed macros. The old behaviour for backwards compatibility can be restored with 
--useVersion:1.0.
    let statements can now be used without a value if declared with importc/importcpp/importjs/importobjc.
    The keyword from is now usable as an operator.
    Exceptions inheriting from system.Defect are no longer tracked with the .raises: [] exception tracking mechanism. This is more consistent with the built-in operations. The following always used 
to compile (and still does):

    proc mydiv(a, b): int {.raises: [].} =
      a div b # can raise an DivByZeroDefect

    Now also this compiles:

    proc mydiv(a, b): int {.raises: [].} =
      if b == 0: raise newException(DivByZeroDefect, "division by zero")
      else: result = a div b

    The reason for this is that DivByZeroDefect inherits from Defect and with --panics:on Defects become unrecoverable errors.
    Added the thiscall calling convention as specified by Microsoft, mostly for hooking purposes.
    Deprecated the {.unroll.} pragma, because it was always ignored by the compiler anyway.
    Removed the deprecated strutils.isNilOrWhitespace.
    Removed the deprecated sharedtables.initSharedTable.
    Removed the deprecated asyncdispatch.newAsyncNativeSocket.

    Removed the deprecated dom.releaseEvents and dom.captureEvents.

    Removed sharedlists.initSharedList, was deprecated and produces undefined behaviour.

    There is a new experimental feature called “strictFuncs” which makes the definition of .noSideEffect stricter. See here for more information.

    “for-loop macros” (see the manual) are no longer an experimental feature. In other words, you don’t have to write pragma {.experimental: "forLoopMacros".} if you want to use them.

    Added the .noalias pragma. It is mapped to C’s restrict keyword for the increased performance this keyword can enable.
    items no longer compiles with enums with holes as its behavior was error prone, see #14004.

    system.deepcopy has to be enabled explicitly for --gc:arc and --gc:orc via --deepcopy:on.
    Added the std/effecttraits module for introspection of the inferred effects. We hope this enables async macros that are precise about the possible exceptions that can be raised.
    The pragma blocks {.gcsafe.}: ... and {.noSideEffect.}: ... can now also be written as {.cast(gcsafe).}: ... and {.cast(noSideEffect).}: .... This is the new preferred way of writing these, 
emphasizing their unsafe nature.

Compiler changes
    Specific warnings can now be turned into errors via --warningAsError[X]:on|off.
    The define and undef pragmas have been de-deprecated.
    New command: nim r main.nim [args...] which compiles and runs main.nim, and implies --usenimcache so that the output is saved to $nimcache/main$exeExt, using the same logic as nim c -r to avoid 
recompilations when sources don’t change. Example:

    nim r compiler/nim.nim --help # only compiled the first time
    echo 'import os; echo getCurrentCompilerExe()' | nim r - # this works too
    nim r compiler/nim.nim --fullhelp # no recompilation
    nim r --nimcache:/tmp main # binary saved to /tmp/main

    --hint:processing is now supported and means --hint:processing:on (likewise with other hints and warnings), which is consistent with all other bool flags. (since 1.3.3).
    nim doc -r main and nim rst2html -r main now call openDefaultBrowser.
    Added the new hint --hint:msgOrigin will show where a compiler msg (hint|warning|error) was generated; this helps in particular when it’s non obvious where it came from either because multiple 
locations generate the same message, or because the message involves runtime formatting.
    Added the new flag --backend:js|c|cpp|objc (or -b:js etc), to change the backend; can be used with any command (e.g. nim r, doc, check etc); safe to re-assign.
    Added the new flag --doccmd:cmd to pass additional flags for runnableExamples, e.g.: --doccmd:-d:foo --threads use --doccmd:skip to skip runnableExamples and rst test snippets.
    Added the new flag --usenimcache to output binary files to nimcache.
    runnableExamples "-b:cpp -r:off": code is now supported, allowing to override how an example is compiled and run, for example to change the backend.
    nim doc now outputs under $projectPath/htmldocs when --outdir is unspecified (with or without --project); passing --project now automatically generates an index and enables search. See docgen for 
details.
    Removed the --oldNewlines switch.
    Removed the --laxStrings switch for mutating the internal zero terminator on strings.
    Removed the --oldast switch.
    Removed the --oldgensym switch.
    $getType(untyped) is now “untyped” instead of “expr”, $getType(typed) is now “typed” instead of “stmt”.
    Sink inference is now disabled per default and has to enabled explicitly via --sinkInference:on. Note: For the standard library sink inference remains enabled. This change is most relevant for 
the --gc:arc, --gc:orc memory management modes.

Tool changes
    nimsuggest now returns both the forward declaration and the implementation location upon a def query. Previously the behavior was to return the forward declaration only.
