Many thanks to SourceForge user 'nyademo' for - pointing this out and developing a fix. - * generic/tclPathObj.c: Corrected a 'const'ness fault that caused - bitter complaints from MSVC. - * tests/clock.test (clock-40.1, clock-58.1, clock-59.1): Corrected a - test case that depended on ":localtime" being able to handle dates - prior to the Posix epoch. [Bug 1618445] Added a test case for the - dates of the Japanese emperors. [Bug 1637471] Added a regression test - for military time zone input conversion. [Bug 1586828] - * generic/tclGetDate.y (MilitaryTable): Fixed an ancient bug where the - military NZA time zones had the signs reversed. [Bug 1586828] - * generic/tclDate.c: Regenerated. - * doc/Notifier.3: Documented Tcl_SetNotifier and Tcl_ServiceModeHook. - Quite against my better judgment.

This explains why the - testsuite did not pick this mistake. Rewrote to make the intention - clear. + * tests/tcltest.test: When creating the notwritabledir we deny the + current user access to delete the file. We must grant this right when + we cleanup.

Removed an outdated + comment in Tcl_DeleteCommandFromToken that claimed we use + cmdPtr->objPtr==NULL as a test of command validity. In fact we use + cmdPtr->flags&CMD_IS_DELETED to perform that test. Also removed the + setting to NULL, since any extension following the advice of the old + comment is going to be broken by NRE anyway, and needs to shift to + flag-based testing (or stop intruding into such internal matters). + Part of [Bug 2486550]. -2006-01-25 Donal K.
