2026-08-29 — Native futex for TOSLightLock and ICU deadlock fix

Sat, 29 Aug 2026 07:00:00 +0000

Today's commits bring a major evolution to the mORMot 2 core synchronization primitives. TOSLightLock now leverages native futex on Linux and WaitOnAddress on Windows 8+, promising significant contention performance gains. In addition, an ICU library deadlock was fixed and the async networking polling got a boundary check.

TOSLightLock uses native futex on Linux and WaitOnAddress on Windows 8+.
TIcuLibrary fixes a deadlock during shared converter creation.
TAsyncConnections fixes a potential out-of-range bug in thread polling.
Adaptive spin-wait mechanisms are extracted to the core base unit.

2026-08-28 — Thread wake-up goes lockless, and two API moves worth grepping for

Fri, 28 Aug 2026 07:00:00 +0000

Today is mostly about the asynchronous server core. The thread-wakeup path used by every async HTTP, WebSocket and TFTP server drops its lock in favour of two atomic counters, which should show up as less contention on busy multi-core boxes. Around that, two smaller changes deserve a grep through your own code: TOrmTable.GetAsVariant and ToDocVariant changed their parameter from out to var, and the mORMot 1 compatibility function Lecuyer moved to another unit. Everything else is internal cleanup.

Async server thread wake-up is now lockless: two CAS counters replace the TLightLock that guarded acoThreadSmooting.
TOrmTable.GetAsVariant and TOrmTable.ToDocVariant now take var instead of out — the destination variant is no longer cleared for you.
The legacy Lecuyer function moved from mormot.core.base to mormot.crypt.core and now returns the shared ThreadRandom generator.
TLoggedThread gained an ExecuteDone property, standing in for the RTL Finished property on older compilers.
The TFTP server compiles again on Delphi 7 and 2007 after last week's worker-lifetime fix.
