| Description: |
Bytecompiling [uplevel]ed scripts (see uplevel.patch below) causes two failures in encoding.test: 2.2 and 11.1. Only the first is of concern, the second failure can be shown to be an artifact of the first. The problem seems to be that when the string "shiftjis" is stored as a shared literal, its intRep is not spoiled at the appropriate time. Please see http://paste.tclers.tk/952 for a demo of the bug in a standard tclsh, and the attached analysis (kbk at the chat). | |||

Logged In: YES user_id=80530 Originator: NO Backported same workaround to 8.5 branch where those tests have also recently started to fail. dgp added on 2008-06-20 23:18:12: Logged In: YES user_id=80530 Originator: NO Added shimmer-inducing commands to the tests so they will stop failing. Better would be to more fully determine what's really being tested; whether the test is even still valid; and if so, construct a more robust direct test, perhaps even with a custom Tcltest command for that purpose. msofer added on 2008-06-09 20:46:37: Logged In: YES user_id=148712 Originator: YES That patch has been committed to HEAD now dkf added on 2008-05-26 23:52:51: Logged In: YES user_id=79902 Originator: NO TclOO used to hit a lot of this general sort of problem. I dealt with them by giving each object its own unique sequence number; maybe sequence/epoch numbers are the easiest way for checking whether the internal rep is valid here too? msofer added on 2008-05-26 20:09:41: File Added - 279076: [email protected] Logged In: YES user_id=148712 Originator: YES File Added: [email protected] msofer added on 2008-05-26 20:08:44: File Added - 279075: uplevel.patch | |||
