I guess what I wanted to say is that it might be desirable to have the klibc shell do some dancing (perhaps controlled by some flags, but on by default?) If getpid() == 1 then fork a child, continue in the child, have the parent wait for the child to terminate, then exit child should setsid() close(2) close(1) close(0) open("/dev/ttyS0", O_RDONLY) open("/dev/ttyS0",

...or hvc0 normally ? plus, if it fails you get a message and can retry). My point here, asking for this change, is: normally you do *not* need full job control right from the start. But you *do* want to have PS1 and working command line editing (e.g. tab completion). For this, /dev/console must be isatty(). bye, //mirabilos -- FWIW, I'm quite impressed with mksh interactively. I thought it was much *much* more bare bones. But it turns out it beats the living hell out of ksh93 in that respect. I'd even consider it for my daily use if I hadn't wasted half my life on my zsh setup. :-) --...

The 4.6p1 sshd is logging this error during remote commands or file transfers: error: channel 0: chan_read_failed for istate 3 Platform is Solaris 8, 4.6p1 + OpenSSL 0.9.8d. The commands and transfers work correctly, so the error message appears to be spurious. The error message does not appear when processing logins. Otherwise 4.6p1 is running without any apparent problems. This error

Does ctrl+c work? My experience with (non klibc) init=/bin/bash is that getting ctrl+c to work requires some jumping through hoops, because running as pid 1 doesn't really work. If I recall correctly you have to call setsid, and open a tty as a controlling tty, you can't call setsid as pid 1. The hack that I got to work (for reference, I'm using this for raw kernel testing

Nope. An easy solution (both here and for clang) is for ninja to set an environment variable (`NINJA_ISATTY`?), and add some magic to LLVM's "isatty" to return true if it sees it. (for matters of correctness, it would actually be best if ninja sets the environment variable only when *it's* stdout/stderr isatty (also taking into account this environment variable), so that everything wor...

I'm just wondering if anyone's using Ninja (which buffers output from subcommands, such as lit/FileCheck/etc) & has thought about/found a way to force FileCheck to use colour in spite of Ninja's buffering. Thanks, - David

I'm a little unsure what you mean by "LLVM's 'isatty'" - isn't that just a system call LLVM would be making? (I suppose we probably have a wrapper somewhere to handle platform-s...

...re build changes required though and may be > incompatibilities between unix bison and windows bison. If these were > worked out and solved, I would like to see this happen :) In my experience the only difference between recent bison versions on unix vs win32 is the inclusion of unistd (for isatty()). This is easily solved by adding a dummy unistd.h header which either defines isatty as a macro which always evaluates to zero, or actually implementing the function in a separate source file for win32. The first option would be preferred since the only required change would be an added include...

...the input and not read lines until the buffer is exceeded or StdIn is closed by the sending process. This prevents interactive communication between a calling process and a child R process. >From a quick look at the source code, it looks like the bug is caused by only disabling buffering when isatty() returns true for a file descriptor (connections.c). This fixes the original bug when the script is run in a terminal, but doesn't help for pipes, which will return false for isatty(). An example R script and python script are provided to demonstrate the problem: R script (example.r): ======...

...ailed, it places the error into pending socket error, where it is later pulled up by select()/poll(). However OpenSSH does a bunch of other stuff between connect() and select(). In particular, it calls channels.c:channel_register_fds. And the Portable OpenSSH (not "pure" OpenSSH) invokes isatty() here. On Solaris, isatty() invokes underlaying ioctl() which gets and clears the pending socket error. Therefore on Solaris, there is a race condition when the following happens: - OpenSSH invokes connect() which returns EINPROGRESS - connection attempt outcome is known after a while and is plac...
