| Description: | ||||
The "<<" [exec] redirection operator truncates its operand at the first NUL. Similar does not happen when writing to an [open |] channel. % exec xxd << ab\0cd 0000000: 6162 ab % exec xxd << ab\1cd 0000000: 6162 0163 64 ab.cd % set chan [open |xxd a+]; puts -nonewline $chan ab\0cd; close $chan write; read $chan 0000000: 6162 0063 64 ab.cd | ||||

This is fixed in 8.5.12 and 8.6b3 . You must not really be testing what you think you are testing. Use [package present Tcl] to confirm. % package present Tcl 8.6b3 % exec xxd << ab\0cd 0000000: 6162 0063 64 ab.cd % andygoth added on 2012-09-28 22:20:46:
Sorry for picking the wrong version, I meant 8.6b2. Also I tested on 8.4.something, forget exactly what, but it was nowhere close to the latest 8.4. dgp added on 2012-09-28 22:34:40:
