Rodrigo Mesquita pushed to branch wip/romes/24212 at Glasgow Haskell Compiler / GHC Commits: ea2c6673 by Teo Camarasu at 2025-07-08T13:24:43-04:00 Implement user-defined allocation limit handlers Allocation Limits allow killing a thread if they allocate more than a user-specified limit. We extend this feature to allow more versatile behaviour. - We allow not killing the thread if the limit is exceeded. - We allow setting a custom handler to be called when the limit is exceeded. User-specified allocation limit handlers run in a fresh thread and are passed the ThreadId of the thread that exceeded its limit. We introduce utility functions for getting and setting the allocation limits of other threads, so that users can reset the limit of a thread from a handler. Both of these are somewhat coarse-grained as we are unaware of the allocations in the current nursery chunk. We provide several examples of usages in testsuite/tests/rts/T22859.hs Resolves #22859 - - - - - 03e047f9 by Simon Hengel at 2025-07-08T13:25:25-04:00 Fix typo in using.rst - - - - - 67957854 by Ben Gamari at 2025-07-09T09:44:44-04:00 compiler: Import AnnotationWrapper from ghc-internal Since `GHC.Desugar` exported from `base` has been deprecated. - - - - - 813d99d6 by Ben Gamari at 2025-07-09T09:44:44-04:00 ghc-compact: Eliminate dependency on ghc-prim - - - - - 0ec952a1 by Ben Gamari at 2025-07-09T09:44:44-04:00 ghc-heap: Eliminate dependency on ghc-prim - - - - - 480074c3 by Ben Gamari at 2025-07-09T09:44:44-04:00 ghc-heap: Drop redundant import - - - - - 03455829 by Ben Gamari at 2025-07-09T09:44:45-04:00 ghc-prim: Bump version to 0.13.1 There are no interface changes from 0.13.0 but the implementation now lives in `ghc-internal`. - - - - - d315345a by Ben Gamari at 2025-07-09T09:44:45-04:00 template-haskell: Bump version number to 2.24.0.0 Bumps exceptions submodule. - - - - - 004c800e by Ben Gamari at 2025-07-09T09:44:45-04:00 Bump GHC version number to 9.14 - - - - - eb1a3816 by Ben Gamari at 2025-07-09T09:44:45-04:00 Bump parsec to 3.1.18.0 Bumps parsec submodule. - - - - - 86f83296 by Ben Gamari at 2025-07-09T09:44:45-04:00 unix: Bump to 2.8.7.0 Bumps unix submodule. - - - - - 89e13998 by Ben Gamari at 2025-07-09T09:44:45-04:00 binary: Bump to 0.8.9.3 Bumps binary submodule. - - - - - 55fff191 by Ben Gamari at 2025-07-09T09:44:45-04:00 Win32: Bump to 2.14.2.0 Bumps Win32 submodule. - - - - - 7dafa40c by Ben Gamari at 2025-07-09T09:44:45-04:00 base: Bump version to 4.22.0 Bumps various submodules. - - - - - ef03d8b8 by Rodrigo Mesquita at 2025-07-09T09:45:28-04:00 base: Export displayExceptionWithInfo This function should be exposed from base following CLC#285 Approved change in CLC#344 Fixes #26058 - - - - - 01d3154e by Wen Kokke at 2025-07-10T17:06:36+01:00 Fix documentation for HEAP_PROF_SAMPLE_STRING - - - - - ac259c48 by Wen Kokke at 2025-07-10T17:06:38+01:00 Fix documentation for HEAP_PROF_SAMPLE_COST_CENTRE - - - - - 2b4db9ba by Pi Delport at 2025-07-11T16:40:52-04:00 (Applicative docs typo: missing "one") - - - - - ccef90b4 by Rodrigo Mesquita at 2025-07-14T13:49:35+01:00 ghc-toolchain: Use ByteOrder rather than new Endianness Don't introduce a duplicate datatype when the previous one is equivalent and already used elsewhere.

Moreover, it removes all the now-redundant entries from `lib/settings` that are configured as part of a `Target` but were being written into `settings`. This makes it easier to support multiple targets from the same compiler (aka runtime retargetability). `ghc-toolchain` can be re-run many times standalone to produce a `Target` description for different targets, and, in the future, GHC will be able to pick at runtime amongst different `Target` files. This commit only makes it read the default `Target` configured in-tree or configured when installing the bindist. The remaining bits of `settings` need to be moved to `Target` in follow up commits, but ultimately they all should be moved since they are per-target relevant.
