From 48d6a20861f95be856bef0e780c054757c9c3803 Mon Sep 17 00:00:00 2001 From: "jan.nijtmans" Date: Wed, 10 Jan 2018 14:02:03 +0000 Subject: Re-implement Tcl_WinTCharToUtf/Tcl_WinUtfToTChar in pure win32 api, even for TCL_UTF_MAX=3. We can do that now safely, because of the changed handling of valid 4-byte UTF-8 characters in the previous commit. --- generic/tclEvent.c | 1 - generic/tclIOUtil.c | 9 ------ generic/tclInt.h | 1 - generic/tclIntPlatDecls.h | 4 +++ generic/tclStubInit.c | 39 +++++++----------------- unix/tclUnixInit.c | 6 ---- win/tclWin32Dll.c | 76 ++--------------------------------------------- win/tclWinInit.c | 7 ----- 8 files changed, 17 insertions(+), 126 deletions(-) diff --git a/generic/tclEvent.c b/generic/tclEvent.c index 49fd2ae..93cf983 100644 --- a/generic/tclEvent.c +++ b/generic/tclEvent.c @@ -1057,7 +1057,6 @@ TclInitSubsystems(void) * mutexes. */ TclInitIOSubsystem(); /* Inits a tsd key (noop). */ TclInitEncodingSubsystem(); /* Process wide encoding init. */ - TclpSetInterfaces(); TclInitNamespaceSubsystem();/* Register ns obj type (mutexed). */ subsystemsInitialized = 1; } diff --git a/generic/tclIOUtil.c b/generic/tclIOUtil.c index 8fb3aa8..144bab0 100644 --- a/generic/tclIOUtil.c +++ b/generic/tclIOUtil.c @@ -830,15 +830,6 @@ TclResetFilesystem(void) if (++theFilesystemEpoch == 0) { ++theFilesystemEpoch; } - -#ifdef _WIN32 - /* - * Cleans up the win32 API filesystem proc lookup table.
