be digging itself deeper into a hole, it forks off a subprocess
that locates files with too many discontinuities and rewrites them, if
there is enough room.
Optionally the user can manually coaleasce files by running with "-c".
The recent change to lfs_markv is required for the coalescer to do anything.
All of "digging itself deeper", "too many discontinuities", and "enough room"
need to be better defined.
as well as bi_daddr. This lets the cleaner have an idea of what the size
of this block was at the time it was written without having to refer to
a segment header (e.g., in the file coalescing case).
Tested on i386.
-cut yhe trailing '\r' from input lines so that commands are recognized
-use db_vprintf() for output in interactive mode to get the "|more" effect
-do the same setjmp() game as ddb, so we can return to the prompt
- First implementation of procblk(). THis is supposed to suspend processes.
We emulate this by sending a SIGSTOP, which is not very accurate since
on IRIX, sending a SIGCONT to a process suspended by procblk() will not
resume it.
- support for shared groups
Reenable statistics interrupts, reading it as 16bit caused it to not be cleared,and thus the eventual interrupt to not be cleared (and this caused an
infinite loop in interrupt routine).
While I'm there count STE_CarrierSenseErrors as oerror (this is incremented
each time we try to send a packet and the link is down).
- when a transmit underrun occurs, only reset the transmit logic. This prevents
the link from going down at the MII level (the same logic can probably
be used for other transmit errors)
- set the urgent threshold to half the start threshold. From experiments
this helps a bit decreasing the number of underruns
Now that underruns don't cause the interface to stop for several seconds,
make back out the default transmit threshold to 128.
- Add `no' keyword, which can be used in the following ways:
no file-system SOMEFS
no makeoptions FOO
no options OPT1[,OPT2[,...]]
no pseudo-device somepseudo
This turns off a previous file-system/makeoptions/options/pseudo-device
entry for the same item.
Grammar support for 'no device DEV at ATTACH' added, but not
implemented yet.
Code changes:
- Convert many simple lists to TAILQs
- Convert prefix to SLIST
- Remove argument names from prototypes.
- Don't bother with custom alloc code for hashtables; just use emalloc()
like everything else.
- Implement ht_remove(), to remove an entry from a hash table.
Add removed entries to a freelist for later reuse.
- Don't selectbase() devices and pseudo-devices at definition time; instead
do it at one pass after the config file has been parsed in fixdevis().
- Rename nvhead to nvfreelist; a more apt name...
- Minor code cleanups.
elapsed time. (suggested by simonb)
- actually display transfer stats after a URL fetch. (bug introduced a
*long* time ago)
- update copyright & version
