Stephen Heumann 16cd3c0619 Merge with BusyBox 1.24.0.
There's really only one bug fix in here that should be significant for GNO hush. The other changes should be inconsequential, AFAIK.

Stephen Heumann d305e3b821 Fix a bug where numbers could be truncated to four decimal digits in certain circumstances.
This affected values from $RANDOM, and could potentially also result in corruption of pid values if they were large enough.

Stephen Heumann fb9b298ca4 Implement "close-on-exec" functionality for GNO.
We do this by maintaining a mask (for each pid) giving the fds to be closed on exec. We wrap functions that close fds so that their close-on-exec bits can be cleared at that point.

This implementation may close the fds even if the execve operation ultimately fails.

Stephen Heumann b3a419646b Changes to handle the use of \r as newline on the IIgs. 2014-11-08 19:58:11 -06:00
Stephen Heumann cae994bc22 Add an emulation of waitpid that should be better than the one in libc.
In particular, it will buffer information about children other than the one being waited for, so it isn't lost. It can also emulate a non-blocking wait by arranging to interrupt the wait with a signal.

Stephen Heumann a3c32aaa73 Revise terminal control code to use ioctls supported by GNO instead of termios calls that aren't supported. 2014-11-04 19:53:40 -06:00
Stephen Heumann 036b92595c Address some link errors with various small changes.
The most significant change is to at use malloc instead of alloca in the code to evaluate shell arithmetic expressions in shell/math.c.

Denys Vlasenko d6e7672545 less: move "retry-on-EAGAIN" logic closer to read ops
This makes "G" (goto end of input) command work as well as
/search_for_nonexistent_string: both will read to EOF now
even from somewhat slow input (such as kernel's "git log").
