* fix int32's that should be uint32 on BSD & OSX (#24078)metagn2024-09-092-10/+10
| | | | | | | | | fixes #24076 As described in #24076, misannotating these types causes codegen errors. Sources for the types are https://github.com/openbsd/src/blob/master/sys for BSD and https://opensource.apple.com/source/Libinfo/Libinfo-391/ and [_types.h](https://opensource.apple.com/source/xnu/xnu-1456.1.26/bsd/sys/_types.h.auto.html) for OSX.
* Fix ioselectors_kqueue raising wrong exceptions (#24079)bptato2024-09-081-2/+6
| | | | | | | | | | | | | | | | | kqueue will remove pipes automatically if their read end is closed. Unfortunately this means that trying to unregister it (which is necessary to clean up resources & for consistency with other ioselectors implementations) will set an ENOENT error, which currently raises an exception. (ETA: in other words, it is currently impossible to call unregister on a pipe fd without potentially getting the selector into an invalid state on platforms with kqueue.) Avoid this issue by ignoring ENOENT errors returned from kqueue. (Tested on FreeBSD. I added a test case to the tioselectors file; the seemingly unrelated change is to fix a race condition that doesn't appear on Linux, so that it would run my code too.)

* expose `rangeBase` typetrait, fix enum conversion warning (#24056)metagn2024-09-061-0/+34
| | | | | | | | | | | | | | | | refs #21682, refs #24038 The `rangeBase` typetrait added in #21682 which gives the base type of a range type is now added publicly to `typetraits`. Previously it was only privately used in `repr_v2` and in `enumutils` since #24052 (coincidentally I didn't see this until now). This is part of an effort to make range types easier to work with in generics, as mentioned in #24038. Its use combined with #24037 is also tested. The condition for the "enum to enum conversion" warning is now also restricted to conversions between different enum base types, i.e. conversion between an enum type and a range type of itself doesn't give a warning. I put this in this PR since the test gave the warning and so works as a regression test.

| | | | | | | | in https://forum.nim-lang.org/t/12463 which seems reasonable enough to me. stdlib has several dozens of places doing result.setLen now, but if `experimental:strictDefs` move sot on by default and there is no easy way to locally suppress the warning we can revisit this.
* streams: implement readStr for VM, document VM limitations (#24058)metagn2024-09-041-3/+12
| | | | | | | | | | | fixes #24054 `readData` is not implemented for the VM as mentioned in the issue, but `readDataStr` is, so that is used for `readStr` instead on the VM. We could also just use it in general since it falls back to `readData` anyway but it's kept the same otherwise for now. Also where and why streams in general don't work in VM is now documented on the top level `streams` module documentation.

* Fix linux start process errorCode always 0 (#24001)握猫猫2024-08-281-4/+7
| | | | | | | | | | | | #23992 The test case provided does not cover the Windows situation, I fixed it in this new PR. Fixed an issue where errorCode was always 0 when startProcess didn't use the poEvalCommand flag. Tthe sleep command might not be available in all Windows installations, so I skipped the relevant test. Added a test case, tested on my fedora and windows systems.
* opensym for templates + move behavior of opensymchoice to itself (#24007)metagn2024-08-282-4/+4
| | | | | | | | | | | | | | | | | | | | | | | fixes #15314, fixes #24002 The OpenSym behavior first added to generics in #23091 now also applies to templates, since templates can also capture symbols that are meant to be replaced by local symbols if the context imports symbols with the same name, as in the issue #24002. The experimental switch `templateOpenSym` is added to enable this behavior for templates only, and the experimental switch `openSym` is added to enable it for both templates and generics, and the documentation now mainly mentions this switch. Additionally the logic for `nkOpenSymChoice` nodes that were previously wrapped in `nkOpenSym` now apply to all `nkOpenSymChoice` nodes, and so these nodes aren't wrapped in `nkOpenSym` anymore. This means `nkOpenSym` can only have children of kind `nkSym` again, so it is more in line with the structure of symchoice nodes. As for why they aren't merged with `nkOpenSymChoice` nodes yet, we need some way to signal that the node shouldn't become ambiguous if other options exist at instantiation time, we already captured a symbol at the beginning and another symbol can only replace it if it's closer in scope and unambiguous.
* remove fauxMatch for tyFromExpr, remove tyProxy and tyUnknown aliases (#24018)metagn2024-08-281-1/+1
| | | | | | | | | | | | | | | | | | | | | updated version of #22193 After #22029 and the followups #23983 and #24005 which fixed issues with it, `tyFromExpr` no longer match any proc params in generic type bodies but delay all non-matching calls until the type is instantiated. Previously the mechanism `fauxMatch` was used to pretend that any failing match against `tyFromExpr` actually matched, but prevented the instantiation of the type until later. Since this mechanism is not needed anymore for `tyFromExpr`, it is now only used for `tyError` to prevent cascading errors and changed to a bool field for simplicity. A change in `semtypes` was also needed to prevent calling `fitNode` on default param values resolving to type `tyFromExpr` in generic procs for params with non-generic types, as this would try to coerce the expression into a concrete type when it can't be instantiated yet. The aliases `tyProxy` and `tyUnknown` for `tyError` and `tyFromExpr` are also removed for uniformity.

* generate symchoice for ambiguous types in templates & generics + handle ↵metagn2024-08-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | types in symchoices (#23997) fixes #23898, supersedes #23966 and #23990 Since #20631 ambiguous type symbols in templates are rejected outright, now we generate a symchoice for type nodes if they're ambiguous, a generalization of what was done in #22375. This is done for generics as well. Symchoices also handle type symbols better now, ensuring their type is a `typedesc` type; this probably isn't necessary for everything to work but it makes the logic more robust. Similar to #23989, we have to prepare for the fact that ambiguous type symbols behave differently than normal type symbols and either error normally or relegate to other routine symbols if the symbol is being called. Generating a symchoice emulates this behavior, `semExpr` will find the type symbol first, but since the symchoice has other symbols, it will count as an ambiguous type symbol. I know it seems spammy to carry around an ambiguity flag everywhere, but in the future when we have something like #23104 we could just always generate a symchoice, and the symchoice itself would carry the info of whether the first symbol was ambiguous. But this could harm compiler performance/memory use, it might be better to generate it only when we have to, which in the case of type symbols is only when they're ambiguous.

* fix #23817; Use __builtin_saddl_overflow variants for arm-none-eabi-gcc. ↵Mark Leyva2024-08-121-3/+11
| | | | | | | | | | | | | | | | | | | | (#23835) Provides a fix for #23817. With target `arm-none-eabi`, GCC defines `int32_t` to `long int`. Nim uses `__builtin_sadd_overflow` for 32-bit targets, but this emits warnings on GCC releases 13 and under, while generating an error on GCC 14. More info regarding this [here](https://gcc.gnu.org/gcc-14/porting_to.html#c) and [here](https://gcc.gnu.org/pipermail/gcc-cvs/2023-December/394351.html). The proposed PR attempts to address this issue for these targets by defining the `nimAddInt`, `nimSubInt`, and `nimMulInt` macros to use the appropriate compiler intrinsics for this platform. As for as we know, the LLVM toolchain for bare metal Arm does not define `int32_t` as `long int` and has no need for this patch. Thus, we only define the above macros for GCC targeting `arm-non-eabi`.

* opensym as node kind + fixed experimental switch (#23892)metagn2024-08-122-2/+4
| | | | | | | | | | | | | | | refs https://github.com/nim-lang/Nim/pull/23873#discussion_r1687995060, fixes #23386, fixes #23385, supersedes #23572 Turns the `nfOpenSym` node flag implemented in #23091 and extended in #23102 and #23873, into a node kind `nkOpenSym` that forms a unary node containing either `nkSym` or `nkOpenSymChoice`. Since this affects macros working on generic proc AST, the node kind is now only generated when the experimental switch `genericsOpenSym` is enabled, and a new node flag `nfDisabledOpenSym` is set to the `nkSym` or `nkOpenSymChoice` when the switch is not enabled so that we can give a warning. Now that the experimental switch has more reasonable semantics, we define `nimHasGenericsOpenSym2`.

* Allocator: Always place free cells into the active chunk and add ↵SirOlaf2024-07-221-21/+96
| | | | | | | | | | | | | | documentation (#23871) Lets single threaded applications benefit from tracking foreign cells as well. After this, `SmallChunk` technically doesn't need to act as a linked list anymore I think, gotta investigate that more though. The likelihood of overflowing `chunk.free` also rises, so to work around that it might make sense to check `foreignCells` instead of adjusting free space or replace free with a counter for the local capacity. For Nim compile I can observe a ~10mb reduction, and smaller ones for other projects.

* Allocator: Track number of foreign cells a small chunk has access to (#23856)SirOlaf2024-07-201-29/+46
| | | | | | | | | Ref: https://github.com/nim-lang/Nim/issues/23788 There was a small leak in the above issue even after fixing the segfault. The sizes of `free` and `acc` were changed to 32bit because adding the `foreignCells` field will drastically increase the memory usage for programs that hold onto memory for a long time if they stay as 64bit.
* Add '.' (period, dot, ..) to `FormatLiterals` so that `ss.fff` can work. ↵c-blake2024-07-191-1/+1
| | | | | | | | | | | | | (#23861) Honestly, to me the entire design of a (highly!) restricted set of `FormatLiterals` characters seems antithetical to the very idea of a format string template. Fixing that is a much larger change, though. So, this PR just adds `'.'` so that the standard (both input & output!) notation for decimal numbers in Nim can be used for the seconds part of a time format in `lib/pure/times.format(.., f)`. It should only make legal what was illegal and should be harmless since `'.'` is not used in any special way otherwise.
