The previous resize optimization now means that the wfill()
is skipped on resize for libdraw programs.
So do it once /dev/mouse is closed and the window processes
the Refresh message.
"" looks for patterns in the form 'prompt;' or 'prompt%',
and gets confused when proof emits 'illegal;'. This change
replaces the ';' with a ':', which both matches other
conventional error outputs and prevents "" from getting
confused.
As long as the client as the mouse file open
and maintains reading the winname file of the window
after a resize we will avoid drawing the text frame
on a resize as it will be overdrawn by the client.
This reduces flicker on resize somewhat for slow systems.
Fixes 3 issues in our upas mkfiles:
- mk/mkfile and send/mkfile were rebuilding
only the rfc822.tab.$O, even though the
header also needed to be rebuilt.
- CLEANFILES had a pattern that would not
get expanded.
- Third, ../upas/mkfile was being included
in the wrong place and making the wrong
rule default.
dc crashes because a Blk* sometimes ends getting double freed.
To make it crash, any of these lines will do:
(each line is a separate input to dc):
1 sa 2 :a le d sa v :a
1 sa 2 :a le d sa :a
1 sa 2 :a le d sa c
Fix by assigning p to sptr->val before EMTPY causes a jump.
Additionally, dcgetwd() can return 0. all other uses check for
0 ptr; Also fix a buffer overflow.
the hid 1.11 specification says that for hid devices which arent in
the boot subclass (subclass 1), it is only optional to support the set
protocol command. for my devices, trying to set protocol results in a
stall error and unusable devices.
fixes my Tex Shinobi keyboard and Playstation 4 controller.
Before the "native" awk work, a call to the fflush function resulted
in one or more calls to the APE fflush(2).
Calling fflush on a stream open for reading has different behavior
based on the environment: within APE, it's a no-op¹; on OpenBSD, it's
an error²; in musl, it depends on whether or not the underlying file
descriptor is seekable³; etc. I'm sure glibc is subtly different.
Now that awk uses libbio, things are different: calling Bflush(2) on a
file open for reading simply discards any data in the buffer. This
explains why we're seeing truncated input. When awk attempts to read
in the next record, there's nothing in the buffer and no more data to
read so it gets EOF and exits normally. Note that this behavior is not
documented in bio(2). It was added in the second edition but I haven't
figured out why or what depends on it.
The simple fix is to have awk only call Bflush on files that were
opened for writing. You could argue that this is the only correct
behavior according to the awk(1) manual and it is, in fact, how GNU
awk behaves⁴.

Changeset 50ad211fb12f broke the libcommon rule in
mkupas. Deleting the 'mk clean' in the recipe fixes
this.
Cleanup includes deleting UPDATE vars from all mkfiles,
reorganization of vars in TARG,LIB,OFILE,HFILE order,
and deletion of extra vars used for UPDATE.
The fsdestroyfid() is called regardless if the open succeeded
or failed. This causes erroneous videoclose() when opening
the frame or video file while the camera is active.
Upas/marshal -F was broken with the '-8' command, and silly
without it: It used aliases passed on the command line, so
the destination address was ignored with -8 was passed.
In addition, it would create a new mailbox for any aliases
being sent to, instead of putting them all in one location.
The new -S option is similar to -F, but specifies where the
message should go.
libcommon.a$O doesn't end with a .a, so mk
doesn't know how to look inside it in order
to check if the files are up to date.
This means that when 'mk clean' is run,
libcommon.a$O looks up to date:
% mk clean
...
% mk
mk: 'default' is up to date
Deleting the library works around this problem.
This prevents VESA bios from accessing the pci
CONFIG_ADDRESS/CONFIG_DATA registers (0xCF8/0xCFC)
directly to access pci config space.
This makes sure the access to pci config space is
properly serialized by the kernel.
vt chording behaves slightly differently from other
applications: a chord must be fully released before
the next chord can be applied. This makes any change
in chord apply the action.
supplying a non-ip address in ADD_EDGE crashes the unix tincd.
the reason was that we where misreporting ADD_EDGE messages;
ignoring the information from our peers; and always supplying
the Address string from our configuration instead of the
connections ip address.
now we just report the edge information as is.
When moving messages between folders, mbappend,
deliver, and nedmail were trying to parse the
timestamp ouut of the message. They were doing
it incorrectly, trying to include the user name
as part of the date format.
Change to pass just the date to the date parser.
I have the problem that i need to delegate a subdomain
to another name server that is confused about its own zone
(and its own name) returning unusable ns records.
With this, one can make up a nameserver entry in ndb that
is authoritative and owned by us for that nameserver,
and then put it in the soa=delegated ns entry.
This promotes the ns record in the soa=delegated to
Authoritative, which avoids overriding the ns rr's from
the confused server for the delegated zone.
we used to only allocate ports from 6881 to 6890,
which limits the maximum of parallel torrents to 9.
this change make it go up to 9000, which gives us
at best 2120 ports, which is overkill but ports might
be randomly occupied by other connections.
the new date format introduced by the previous commit;
using numeric timezone offsets; needs one character more,
so increase the date format buffer to 31 characters.
Complete the conversion of upas to remove ctime,
use the new date library, and print time zones
in +hhmm format, instead of NNN format.
This may affect code that expects specific names
for timezones. Fix that code.
Recently the script which generates tab.h and the code including it got
incompatibly changed. People reported problems involving syntax errors
when trying to rebuild the system following a sysupdate.
The problem was with the script being embedded within a mkfile rule,
meaning that mk didn't notice it changing and therefore didn't rebuild
the target file. For people who were rebuilding the system this meant
that the old tab.h got included, causing syntax errors.
This patch moves the codegen script into a file and tells mk about this
new dependency, so that tab.h will get rebuilt for everyone. I also
took an opportunity to rewrite the script, hopefuly making it easier to
follow.
