which defaults to 1024 as before.
- Add two ioctls TIOC{G,S}QSIZE to read and adjust the queue size on
individual ptys.
NB: ttys (and ptys) still silently (or beepingly (IMAXBEL)) drop
characters if the queue size is exceeded. I.e. you can appear
to succeed writing to the {p,t}ty, but not all characters will
have made it if the queue overflows. CVS:
- Don't use TTYHOG - 1, you can use the last byte in the ring buffer.
- Don't put unnecessary if statements around the code. The loop invariant
is that if you reach the top of the loop, cc == 0.
- Remove cast to (void *).
- Check result of b_to_q and adjust cc.
- Explain what the TTYHOG - 2 code tried to do, and do it right.
files is empty. Sometimes the variable contains one or more spaces,
and testing against "" gave the wrong result, but applying the
:M* modifier discards the spaces. This should fix PR 45396.
* Instead of using "-" to ignore the exit status from the rm command,
use ||true. This should work around the bug in PR 45356, but that
bug is not fixed.
* Suppress the ${MKMSG} command with .if 0. People who build with
MAKEVERBOSE=1 don't want to see the message, and people who build
with MAKEVERBOSE=2 or higher will see the actual rm command. The
message may be useful for debugging this makefile itself, so it's
only disabled, not deleted.
RUMP-visible code. Instead of checking that updateproc (aka ioflush,
aka syncer) will not sleep in PUFFS code, I check for any kernel thread:
after all none of them are designed to hang awaiting for a remote filesystem
operation to complete.
nocoredump filesystems to avoid dumping on them) only worked for core
filenames that dump in the current working directory. Update the code to
validate the mount point of the parent directory of the core file if needed.
slightly modified by me to profit from runtime checks for dom0 privileges
instead of using compile time macros (DOM0OPS).
It should now be possible to use pkgsrc's sysutils/xentools inside
a domU to query XenStore entries (or even modify part of it if the domain
has enough rights).
DMA buffers with cacheing disabled but things like write combining, relaxed
ordering etc. allowed when the CPU supports it
so far enabled only on Loongson, should work on R1xk and probably newer CPUs
