Tilting allows using left/right rotated or invetrted display orientation.
This can be changed at runtime such as: echo tilt right > /dev/vgactl
This removes the old panning and vga overlays as they are only implemented
with some ancient vga controllers.
The idea is to avoid the magic files that contain
per process information in devcons when possible.
It will make it easier to deprecate them in the future.
Provide a central function to change the user id
of the calling process.
This is mostly used by programs to become the none
user, followed by a call to newns().
hget supports adding custom headers with -r;
it makes sense for hpost to do the same, both
because custom headers are more likely necessary
with POSTs, and for consistency.
The initial protocol handling in exportfs for
cpu and import services is a huge mess.
Saparate the code out into its own program with
its own oexportfs(4) manpage.
The OCEXEC flag used to be maintained per channel,
making it shared between all the file desciptors.
This has a unexpected side effects with regard to
channel passing drivers such as devdup (/fd),
devsrv (/srv) and devshr (/shr).
For example, opening a /srv file with OCEXEC
makes it impossible to be remounted by exportfs
as it internally does a exec() to mount and
re-export it. There is no way to reset the flag.
This change makes the OCEXEC flag per file descriptor,
so a open with the OCEXEC flag only affects the fd
group of the calling process, and not the channel
itself.
On rfork(RFFDG), the per file descriptor flags get
copied.
On dup(), the per file descriptor flags are reset.
The second modification is that /fd, /srv and /shr
should reject the ORCLOSE flag, as the files that
are returned have already been opend.
The -v flag now does not create a new rio window,
while -w flag does (restores the old behaviour).
This allows vmx to run under vncs and is in general
mode aligned to other emulators and programs.
Initially the code tried to guess the date format. This
turned out to be a bit too magical, so the feature was
removed, but the manpage still documented the nonfeature.
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.
Ignoring '?' when formatting date strings allows
the format strings to be reused for parsing. This
is convenient, since we don't need to duplicate
the format strings.
The format produced by `diff -u` is inferior to that
produced by `diff -c`, but it's what ape/patch and
unix patch expect, so it's useful to generate it.
This patch adds `diff -u`.
Following is a list of functional changes:
* The -o flag outputs the entire buffer to the length returned
by the syscall, or, in case of fd2path(2) and errstr(2), to '\0'.
* The -x flag is removed; the above makes it possible to pipe
into xd(1) to get the same result.
* The -s flag uses dirfmt(2) to format the stat message, instead
of trying to imitate ls(1).
* Stderr reports are normalized and made easier to parse.
The code also suffered a number of stylistic changes.
There were a number of ideas that were tried out as the tmdate
api evolved. As a result, there were some references in the
manpage to things that are no more.
Fix them.
Ctime is defined as printing a 3-character timezone
name. The timezone name is ambiguous. For example,
EST refers to both Australian and American eastern
time. On top of that, we don't want to make the
tzabbrev table exhaustive. So, we put in this hack:
Before we consult the well known table of timezones,
we check if the local time matches the timezone name.
On top of that, tm2sec
If you want unambiguous timezone parsing, use numeric
timezone offsets (Z, ZZ formats).
We almost always want to skip leading whitespace in time
formats, so make tmparse just do it. This fixes upas mbox
parsing, which leaves a leading whitespace at the start of
the date.
The current date and time APIs on Plan 9 are not good. They're
inflexible, non-threadsafe, and don't expose timezone information.
This commit adds new time APIs that allow parsing arbitrary
dates, work from multiple threads, and can handle timezones
effectively.
this breaks the sample from the seconds manpage, and overall
produces funky results. this needs alot more testing.
term% seconds '23 may 2011'
seconds: tmparse: invalid date 23 may 2011 near 'may 2011'
term% seconds '2019-01-01 00:00:00'

Redo date handling in libc almost entirely. This allows
handling dates and times from outside your timezones,
fixes timezone loading in multithreaded applications,
and allows parsing and formatting using custom format
strings.
As a test of the APIs, we replace the formatting code in
seconds(1), shrinking it massively.
The last commit missed a few removals, and made it
unnecessarily hard to do an update.

Added a ver= field to the filter to distinguish the ip version.
By default, a filter is parsed as ipv6, and after parsing
proto, src and dst fields are converted to ipv4. When no
ver= field is specified, a ip version filter is implicitely
added and both protocols are parsed.
This change also gets rid of the fast compare types as the
filed might not be aligned correctly in the packet.
This also fixes the ifc= filter, as we have to check any
local address.
The new command marks the target window as a scratch window -- a window
whose state cannot be "dirtied" by changes made to its body, therefore
avoiding warnings about unsaved changes when deleting the window or
exiting acme.
Existing examples of scratch windows are error, directory, and guide
windows, whose scratchness is set internally.
With the new command users and programs alike can create their own
scratch windows. This is put to use in acme's own win(1).
This makes the flagfmt parser more robust and accepting
a looser input language — namely by allowing whitespace
around specifier fields and ignoring any empty fields.
Long flagfmts can thus be pleasingly displayed:
flagfmt='
a, b, c, C:cache,
m:mtpt mountpoint,
s:srvn srvname'
Fix inconsistencies between programs and their usage
messages, correct instances where information seems
to be missing or lost. This includes missing arguments,
making usage consistent with manuals, and so on.
with the latest changes to shr(3), we can use ORCLOSE on
the control file to get the mount in the share automatically
removed when the server exits or something goes wrong during
postsharesrv().
do not expose postfd() and sharefd() functions. they where
undocumented and leak the control file descriptors.
with the -s flag, we should read 9P messages from
standard *INPUT* (fd 0) and write responses to
standard *OUTPUT* (fd 1).
before these servers where reading from fd 1,
assuming they where both the same files.
it is unclear how Srv.nopipe flag should work inside
postmountserv(). if a server wants to serve on stdio
descriptors, he can just call srv() after initializing
Srv.infd and Srv.outfd.
The Srv.leavefdsopen hack can be removed now that acme
win has been fixed.
