Duncan Coutts pushed to branch wip/dcoutts/idle-gc at Glasgow Haskell Compiler / GHC Commits: 86bd9bfc by fendor at 2026-03-17T23:46:09-04:00 Introduce `-fimport-loaded-targets` GHCi flag This new flag automatically adds all loaded targets to the GHCi session by adding an `InteractiveImport` for the loaded targets. By default, this flag is disabled, as it potentially increases memory-usage. This interacts with the flag `-fno-load-initial-targets` as follows: * If no module is loaded, no module is added as an interactive import. * If a reload loads up to a module, all loaded modules are added as interactive imports. * Unloading modules removes them from the interactive context. Fixes #26866 by rendering the use of a `-ghci-script` to achieve the same thing redundant. - - - - - e3d4c1bb by mniip at 2026-03-17T23:47:03-04:00 ghc-internal: Remove GHC.Internal.Data.Eq It served no purpose other than being a re-export. - - - - - 6f4f6cf0 by mniip at 2026-03-17T23:47:03-04:00 ghc-internal: Refine GHC.Internal.Base imports Removed re-exports from GHC.Internal.Base. This reveals some modules that don't actually use anything *defined* in GHC.Internal.Base, and that can be pushed down a little in the import graph. Replaced most imports of GHC.Internal.Base with non-wildcard imports from modules where the identifiers are actually defined.

This works because we only ever care about it if the respective job is not a cross job. We also statically detect darwin cross jobs in the same way. We only ever have darwin -> darwin cross jobs so this is enough to detect the host reliably. - - - - - f8817879 by mangoiv at 2026-03-17T23:48:44-04:00 ci: mark size_hello_artifact fragile on darwin x86 The size of the x86_64 hello artifact is not stable which results in flaky testruns.

This avoids all the problems with using signals. In practice, all supported platforms were probably using the non-signal tickers already, which is probably why we do not get lots of reports about deadlocks and other weirdness: we were definately using functions that are not async signal safe in the tick handler (such as fflush to flussh the eventlog). Only Solaris was explicitly using the timer_create ticker impl, and even Solaris could probably use the pthreads one (if anyone cared: Solaris is no longer a Teir 3 supported platform). Plausibly the only supported platform that this will change will be AIX, which should now use the pthreads impl. - - - - - b2bd2031 by Duncan Coutts at 2026-03-20T14:35:41+00:00 Tidy up some timer/ticker comments elsewhere - - - - - 33cb0627 by Duncan Coutts at 2026-03-20T14:35:41+00:00 Remove now-unused install_vtalrm_handler Support function used by both of the signal-based ticker implementations. - - - - - 2a3c5355 by Duncan Coutts at 2026-03-20T14:36:24+00:00 No longer probe for timer_create in rts/configure It was only used by the TimerCreate.c ticker impl. - - - - - 77f009cc by Duncan Coutts at 2026-03-22T14:50:01+00:00 Note that rtsTimerSignal is deprecated. - - - - - 08ce2396 by Duncan Coutts at 2026-03-22T14:52:23+00:00 Add an FdWakup module for posix I/O managers This will be used to implement wakeupIOManager for in-RTS I/O managers. It provides a notification/wakeup mechanism using FDs, suitable for situations when I/O managers are blocked on a set of fds anyway. - - - - - e83a7b27 by Duncan Coutts at 2026-03-22T14:52:23+00:00 Add prompt shutdown to the pthread ticker implementation. The Linux timerfd ticker monitors a pipe which is used by exitTicker to ensure a prompt wakeup and shutdown. The pthread ticker lacked this and so would only exit at the next ticker wakeup (10ms by default). This patch adds the same mechanism to the pthread ticker. This changes the pthread ticker from waiting by using nanosleep() to waiting using either ppoll() or select(), so that it can wait on both a time and a file descriptor. On Linux at least, a test program to compare the timing jitter of these APIs shows that using nanpsleep, ppoll or select makes no statistical difference to the maximum or average jitter. This is a step towards unifying the posix ticker implementations, so that we can have just one portable one (albeit with some limited cpp). It is also a step towards using the ticker as part of a more general implementation of wakeUpRts, since this will require a method to wake the rts from a signal handler context (ctl-c handler). - - - - - 972b07ec by Duncan Coutts at 2026-03-22T14:52:23+00:00 Update ticker header commentary It was antique and didn't apply even to the previous implementation, and certainly not to the updated one. - - - - - c81a29c1 by Duncan Coutts at 2026-03-22T14:54:00+00:00 Remove the timerfd-based ticker implementation There does not appear to be any remaining advantage on Linux to using the timerfd ticker implementation over the portable one (using ppoll on Linux for precise timing). The eventfd implementation was originally added at a time when Linux was still using a signal based implementation. So it made sense at the time. See (closed) issue #10840. - - - - - c5e86753 by Duncan Coutts at 2026-03-22T14:55:37+00:00 Consolodate to a single posix ticker implementation Previously we had four implementations, two using signals and two using threads. Having just one should make behaviour more consistent between platforms, and should make maintenance easier. - - - - - 302 changed files: - .gitlab/ci.sh - compiler/GHC/Driver/Flags.hs - compiler/GHC/Driver/Session.hs -
