* threaded alloc (#20492)Andreas Rumpf2022-10-091-106/+225
| | | | | | | | * allocator: catch up with multi-threading techniques * removed the global thread lock * more atomics for fun and profit * added important sysAssert * stats remain thread local and don't have to be atomic * undo split chunk optimizations in the hope it makes the CI happy

* Freeing critical sections via atexit in system/alloc and system/io (#19062)Tail Wag Games2021-10-291-0/+3
| | | | | | | | | | | | | | | * adding new system module sysexitprocs and including system exit procedures when registering exit handlers defined in userland * fixing failing tests and adding initialization guard to handle cases where the module's global init logic isn't invoked first as is the case with some gc implementaions * js backend shouldn't try to invoke actual system exit procs * fixing formatting in sysexitprocs.nim * 256 was too much - my max number of plugins in my engine is 64 and I require two hooks per runtime it looks like with tls emulation turned off, so for my purposes 128 should be sufficient * so atExit should be enough here, can get rid of all the extra cruft I had added on top since I didn't realize atExit already provided a stack * done being cute - since newruntime prevents correct cpp codegen for object variants apparently and breaks tests if I try to use std/exitprocs, ddSysExitProc is just going into both modules. Since system doesn't include system/io, polluting system with it doesn't make sense either... at least it is only importc'd when it is required in either module and we don't have to have any weird when defined(nimOwnedEnabled) with a comment explaining why
* fixes #18494 (#18783)Andreas Rumpf2021-09-021-8/+34

* added `nimAllocPagesViaMalloc` switch (#18490)Andreas Rumpf2021-07-151-1/+2

| | | | | | | | | | | | | | | | | | | | | | | | | allocShared0. (#13190) * Cleanup, remove lib/system/allocators.nim. seqs_v2 and strs_v2 now use allocShared0 by default. * Fixed -d:useMalloc allocShared / reallocShared / deallocShared. These now use the alloc/dealloc/realloc implementation that also takes care of zeroing memory at realloc. * Removed debug printfs * Removed unpairedEnvAllocs() from tests/destructor/tnewruntime_misc * More mmdisp cleanups. The shared allocators do not need to zero memory or throw since the regular ones already do that * Introduced realloc0 and reallocShared0, these procs are now used by strs_v2 and seqs_v2. This also allowed the -d:useMalloc allocator to drop the extra header with allocation length. * Moved strs_v2/seqs_v2 'allocated' flag into 'cap' field * Added 'getAllocStats()' to get low level alloc/dealloc counters. Enable with -d:allocStats * *allocShared implementations for boehm and go allocators now depend on the proper *allocImpl procs
