* MFC r226403:Mikolaj Golub2011-10-211-3/+6
| | | | | | | | | | | | | | | | | | | | In r225809 the intention was to send VEOF only once if STDIN was not a terminal. Unfortunately the fix was incorrect and for flushtime > 0 it keept sending VEOF. Sent VEOF generates ^D\b\b echoed by the terminal, which was reported in bin/161526. Note, we still send VEOF at least once. Otherwise commands like below would hang forever: echo 1 |script /tmp/script.out cat PR: bin/161526 Reported by: Adrian Wontroba <aw1@stade.co.uk>, Stefan Bethke <stb@lassitu.de> Tested by: Stefan Bethke <stb@lassitu.de> Approved by: re (kib) Notes: svn path=/stable/9/; revision=226591

* MFC r225809:Mikolaj Golub2011-10-042-12/+29
| | | | | | | | | | | | | | | | | | | | When script(1) reads EOF from input it starts spinning on zero-byte reads eating 100% CPU. Fix this by skipping select on STDIN after reading EOF -- permanently if STDIN is not terminal and for one second if it is. Also after reading EOF from STDIN we have to pass it to the program being scripted. The previous approach was to write zero bytes into the pseudo-terminal. This does not work because zero-byte write does not have any effect on read. Fix this by sending VEOF instead.

* Mark functions and variables as static.Ed Schouten2010-08-161-15/+14

* Remove WNOHANG flag from wait3().Ed Schouten2010-04-301-15/+9
| | | | | | | | | | | | | | | | | Because script(1) now reliably terminates when the TTY is closed, it may be the case that the call to wait3() occurs just before the child process exits. This causes error codes to be ignored. Just change script(1) to use waitpid() instead of wait3(). This makes it more portable and prevents the need for a loop, since waitpid() only returns a specified process.

* Fix the following bugs:Dag-Erling Smørgrav1998-09-191-19/+27
| | | | | | | | | | | | | | | | | | | | - if a command was specified and script(1) failed to execute it, it would print the name of your shell in the error message instead of that of the command that failed. - since finish() was installed as a SIGCHLD handler, it would often run before the main loop had had time to process the last few bytes of output. This resulted in very strange truncated error messages. - script(1) would almost always return with an exit status of 0, even if the command returned a non-zero exit status. This broke my 'build world, install it and rebuild the kernel' scripts because 'make installworld' would run even if 'make buildworld' had failed. Notes: svn path=/head/; revision=39481
