OriginalBugID: 1370 Bug Version: 8.0.4 SubmitDate: '1999-03-02' LastModified: '1999-10-29' Severity: SER Status: UnAssn Submitter: pat ChangedBy: hobbs OS: Solaris Machine: Other FixedDate: '2000-10-25' ClosedDate: '2000-10-25' Name: Alexandre FERRIEUX ReproducibleScript: fconfigure stdin # does *not* show the proper socket options when it's a socket # same when it's a serial device fileevent stdin readable MyProc # fails when it's a pipe on Windows, *even* in 8.1 ObservedBehavior: The channel type of stdin/out/err are not computed from trhe underlying file descriptor. They are just hypothetized to be console/regular. DesiredBehavior: A few ioctls should be issued on stdin/out/err, and also on the result of [open] (because of [open /dev/fd/N] on Solaris and Linux, which can yield *any* descriptor), to decipher their nature, and attach whatever specific behavior would be given to their kind if created from Tcl (fconfigure options for sockets and serial; reader thread for pipes on 8.1/Windows). | |||

Logged In: YES user_id=75003 Fixed for 8.4a3.

In need of testcases now. andreas_kupries added on 2001-04-10 03:43:23: Logged In: YES user_id=75003 After looking through manpages and tcl sources it seems that most of the required capabilities are available through "isatty" and "fstat" (+ some standardized macros). Note that both "Tcl_MakeFileChannel" and "TclpOpenFileChannel" have to be modified, in the same way. andreas_kupries added on 2001-04-10 02:23:15: Logged In: YES user_id=75003 See also Bug #219146. This is fixed for Win*, but not unixoid systems. Are the necessary ioctls portable or standardized ? | |||
