Per the docs:
the sender SHOULD include a LF, but the
receiver MUST NOT complain if it is not
present.
I typoed away the SHOULD, and got missed the
MUST NOT.
thanks qbit.
the subst utility no longer supports a '-g'
flag, but this was left behind in commit;
this means that the lines listing modified
files were not correctly commented in the
commit header.
This is mostly harmless, but when using an
editor like sam to edit the commit message,
the modified lines would have to be removed
manually.
was testing out the git/import tweaks and accidentally
pushed this commit. No comment on whether we want it,
but it definitely wasn't ready for merge.
Oops.
Often, people (including myself) will write emails that
can almost be applied with git/import. This changes
git/diff and git/import so that things will generally
work even when assembling diffs by hand:
1. git/import becomes slightly more lax:
^diff ...
^--- ...
will both be detected as the start of a patch.
2. git/diff produces the same format of diff
as git/export, starting with paths:
--- a/path/to/file
+++ b/path/to/file
which means that the 'ape/patch -p1' used
within git/import will just work.
So with this, if you send an email to the mailing list,
write up a committable description, and append the
output of git/diff to the end of the email, git/import
should just work.
[this patch was send through the mailing list using the
above procedure, and will be committed with git/import
to verify that it works as advertised]

some more thoughts on this, i think as 0x15*2 is not multiple
of 8, fw rounds the offset to 0x14*2. i have touched to code
to read data from 0x14*2 then ignore the first 2 bytes, just
so it's not confusing. if this causes mac to be read wrong again,
report.
also, some more changes:
1. set the fwname at iwlpci, just to align the behavior with 8000+.
this is a cosmetic change.
2. i have discovered that on device boot/reset/shutdown functions,
our driver slept way much more than it should. the reason for that is,
driver used the function delay() on places where it needs to use
microdelay() instead. i have modified the code to use microdelay().
wpi likely needs similar changes too. i hope that this does not
break the code.
3. zzz a bit more on tx/rx scheduler shutdowns and niclock.
4. openbsd's iwm and linux apparently does not check if ownership
was obtained anymore in their handover functions. instead they
just loop until the hw is ready. aligned the behavior.
see linux commit: 289e5501c3141191dd830957f1d764d3dc14a54f
5. don't take antenna masks from nvm. it's apparently empty
in some cards from 7k family. we will rely on what the fw file gives
us.
6. when the calibration is completed, wakeup the proc that runs
postboot. otherwise that thing sleeps for like 2 whole seconds
even if calibration completed earlier.
i honestly don't think any of these changes will fix 7260 not
being able to get calibration results, but i don't see anything
wrong at all in postboot7000 at this point. i will just hope
these changes somehow make it get calibration results.
NOTE: latest patch on the 9front ml, posted Mon, 14 Feb 2022 15:26:55 +0300
(non functional as of yet)
Some gba cartridges use flash chips produced by a few different
manufacturers for backup memory. A game rom may then try to read the
device id for its flash chip and break if it's the wrong one. There's
no way for us to know which chip is supposed to be there, save for
looking it up in some database. These chips are either 64k or 128k
big. gba(1) hardcodes the id for the SST 64k chip, but games like the
Pokémon ones use a 128k Macronix chip and expect a different id,
completely breaking them.
This patch sets a different default for 128k flash backups, and gives
the ability to set the exact type when creating the save file if it's
really necessary. This new default fixes the Pokémons. The type is
saved in the save file, but this will *not* break existing ones. It
may be that we don't need to worry about the type and just have an id
that corresponds to the right chip size, which is why these defaults
make sense, but I haven't tested more than a dozen roms, mostly since
I don't really know which games use 128k flash.
Before applying this patch the following will fail to open ed
in the '/tmp/s p a c e' folder:
<snip>
% mkdir '/tmp/s p a c e'
% window -cd '/tmp/s p a c e' ed
!pwd
/tmp/s p a c e
!
q
<snap>
After applying the patch the above sequence works as expected,
opening ed in the '/tmp/s p a c e' folder, printing the present
working directory, and quitting ed.
The root cause was a faulty computation of the pointer `s`,
being off by one, leading to any arguments after the
directory path to be skipped.
This regression was introduced in revision:
• 614f1d6268
Thanks umbraticus for finding and reporting the issue.
The device address is highly variable and depends on
all prior enumerated devices.
This can happen with some devices that do not have
a serial number and all devices of the same type
having the same hname.
Using a counter of collisions per hname makes more sense
and is more stable (given that the order devices are
enumerated is deterministic).
This allows mapping incoming filenames to a different name
using regular expressions, followed by subtitutions
of the %[ICE] format strings.
I needed this to have individual cmdline.txt files for
netbooted raspberry pi's. In this example, i map cmdline.txt
to %C, which gets substituted for /cfg/pxe/$ether of the client.
The transitional PCI device ID for block devices is 0x1001, and the
virtio spec says that devices must have the transitional device ID or
0x1040 + the virtio device ID (2).
Mothra does not currently render text inside <samp> tags inline
similar to <code>, but instead treats them like <pre> which is actually
incorrect behavior. The following small patch should fixes issue.
Sometimes, there is the one-off occation when one needs to
pass a huge list in rc...
This change makes devenv track total memory consumption
of environment groups allowing them to grow up to 1MB in
size (including overhead).
(Before, only the variable size was restricted, but
not the amount of files being created).
The maximum value size of a single environment variable
is set to half of the total size, which allows the
occational large value. (But not many of them).
Because we track all memory consuption, it is also
now possible to create around 10k small environment
variales.
A hashtable is added for name lookups and the qid.path
was changed to allow direct indexing into the entry
array without needing a scan lookup.
All smalloc() calls have been removed, exhaustion is
handled with error(Enomem) avoiding deadlock
in case we run out of kernel memory.
This does not have any adverse effect, since yylex never calls mpatov
with a string with leading 0 (and not 0x) that contains non-octal
digits, but the condition was wrong regardless.
Strings for existing codes in the most used server (OpenSSH) just
repeat the error code name. OTOH we like to have wording of the
strings under our control as much as possible, so we can easier find
and process them. Error strings are still usefull as fallback for
compatibility with future versions of the server.
- fix showpage1 only decrementing proc counter once limit is reached;
this blocked having more than one loadpages process after NPROC calls,
since the next one has to wait until the last has exited
- allow procs to skip pages currently being loaded by others; this
forced processes to wait for each other at the same page
- bump NPROC from 4 to 8
- (hack) immediately fork a few times after adding all pages at
startup to force loading a batch of pages in parallel
To avoid a MAXMACH limit of 32 and make
txtflush into an array for the bitmap.
Provide portable macros for testing and clearing
the bits: needtxtflush(), donetxtflush().
On pc/pc64, define inittxtflush()/settxtflush()
as no-op macros, avoiding the storage overhead of
the txtflush array alltogether.
The new rc's exit status will be '' for a successfull
pipeline execution instead of '|'.
This is a bit too tightly coupled, so just use if()
statement instead, handling this in a portable way.
programs that try to use /srv would choke when running
under iostats, because we intercepted operations on the
special, magic fd passing; we should instead give them
access to the real /srv.
when running outside of a repository, we would try to
remove '$msgfile.tmp', but we had never actually set
'$msgfile'.
the error is harmless, but annoying.
The following patch fixes acme display glitches at the bottom fringe
of columns when adding/moving/resizing windows.
Here an example of an easy to reproduce case:
• https://invidio.xamh.de/watch?v=iLekQrxycaM
…opening acme and resizing a column to the right is all that is needed.
The functions winresize(…) and textresize(…) are extended with an
additional parameter `fillfringe` to indicate if a window/tag shall
fill a potential fringe area that would otherwise remain white.
The changes have been inspired by the approach taken in plan9port
acme.
Eckard's test case:
cat <<! | cat
asdf
!
The issue is that we have to continue parsing until we see
the '\n' before consuming the here document.
So we revert to the old approach of having two functions:
heredoc() which remembers if we'v seen a heredoc redirection
and a second readhere() function that reads the doc from
the lexers input and sets Tree.str on thee REDIR node.
due to the way the size of buf was calculated, the parent
file had one trailing null byte for each parent. also, while
we're here, replace the sprint with seprint, and compute the
size from how much we printed in.
Fixup remaining Plan9 dependencies (chartorune()).
Add Makefile for UNIX-like systems (tested with Linux and APE).
Make error printing consistent, use Errstr() explicitely.
Get rid of NSTATUS buffer limit, just malloc it.
git used to track cache size in object
count, rather than bytes. This had the
unfortunate effect of making memory use
depend on the size of objects -- repos
with lots of large objects could cause
out of memory deaths.
now, we track sizes in bytes, which should
keep our memory usage flatter.
Untangle the lexer and interpreter thread state.
Fix the file and line number error reporting, getting rid of
Xsrcfile instruction, as the whole code block can only come
from a single file, stuff the source file in slot[1] of the
code block instead.
Remove limitations for globber (path element limits)
and be more intelligent about handling globbing by
inserting Xglob instruction only when needed and not
run it over every Xsimple argument list.
Remove fragile ndot magic and make it explicit by adding
the -q flag to . builtin command.
Add -b flag for full compilation.
Make exitnext() smart, so we can speculate thru rcmain and
avoid the fork().
Get rid of all print(2) format functions and use io
instead.
Improve the io library, adding rstr() to handle tokenization,
which allows us to look ahead in the already read buffer
for the terminators, avoiding alot of string copies.
Auto indent pcmd(), to make line number reporting more usefull.
Implement here documents properly, so they can work everywhere.
We seem to have a botch in the protocol negotiation, where
we leak some protocol packets into the packfile; this will
need to be fixed before we put this change in.
The initial working directory of a new window may be set by a
`-cd directory` option. However, the `-cd directory` option is
not capable of handling paths with spaces when used via wctl.
To enable paths with spaces the function
/sys/src/cmd/rio/wctl.c:/^parsewctl is extended to handle quoted
directory paths.
Before applying the patch the following will fail to open a new
window by writing to /dev/wctl:
<snip>
% rio -i window
% mkdir '/tmp/path with space'
% echo new -cd '''/tmp/path with space''' window -x rc >> /dev/wctl
% pwd
/tmp/path with space
<snap>
The following invocation fails as well:
<snip>
% window -cd '/tmp/path with space'
% pwd
/tmp/path with space
<snap>
After applying the patch the above sequences work as expected,
opening a window running rc with the working directory set to
'/tmp/path with space'.
exportfs -d logs 9p traffic to /tmp/exportdb.
-f allows writing to a different file.
exportfs silently continues if it doesn't have
permissions to create or write to /tmp/exportdb.
These are poor behaviors.
A better default is to write to stderr, since it
is 9P debug info that is better immediately printed,
and not user info that is better handled by syslog().
As a result, -f is obsolete and thus removed.
Redirect responsibility is now on rc.
As a side effect, rc will fail if it doesn't
have permissions to write.
exportfs(4) is updated to reflect all changes
and with a better Synopsis.
oexportfs is changed to match exportfs.
oexportfs(4) is updated to reflect all changes.
The Synopsis is not changed due to the number of flags.
Removed -f from iostats.
iostats(4) is updated to reflect all changes.

http://fqa.9front.org/fqa1.html#1.2 states the supported archs.
However, clean and nuke also remove build files for 0 (spim) and q
(power). 'mk all' using those archs fails; 'mk kernels' also tries to
build all the kernels, even those which are not supported. For
example, I tried to build the power arch (qc, qa, ql) and without
surprise it failed (when building dtracy): ...

The patch below skips over non-supported architectures. Is that
something we want? This way, 'mk kernels' should work without a
problem (tested on amd64). Then if someone works on getting those
architectures supported again in the future, they can be added back
in.
snoopy shares ndb/dns's dns parser code, but has its own
copy of rralloc() function, which is responsible to allocating
auxiolary data structures on an RR depending on the type.
ndb/dns gained some support for some new types, but snoopy's
copy of rralloc() was not updated, resulting the auxiolary
structures to be nil, and the shared parsing routines crashes
when trying to dereference them.
this just syncs the copies, we might consider moving rralloc()
into its own file so it can be completely shared.
Git currently gets a bit confused if you try to
manipulate files by absolute path. There were also a
number of places where user-controlled file paths ended
up getting passed to regex interpretation, which could
confuse things.
This change mainly does 2 things:
- Adds a 'drop' function which drops
a non-regex prefix from a string, and uses
that to manipulate paths, simplifies 'subst',
and removes 'subst -g', which was only used
with fixed regexes; sed does this job fine.
- When getting a path from a user, we
make it absolute and then strip out the head
Along the way it cleans up a couple of stupids:
- 'for(f in $list) if(! ~ $#f 0) use $f:
$f can't be a nil list because of
list flattening.
- removes a useless substitution here:
all=`$nl{{git/query -c $1 $2; git/query -c $2 $3} | sed 's/^..//' | \
gsubst '^('$ourbr'|'$basebr'|'$theirbr')/*' | sort | uniq}
where git/query -c doesn't produce
paths prefixed with the query.
exportfs -d logs 9p traffic to /tmp/exportdb.
-f allows writing to a different file.
exportfs silently continues if it doesn't have
permissions to create or write to /tmp/exportdb.
These are poor behaviors.
A better default is to write to stderr, since it
is 9P debug info that is better immediately printed,
and not user info that is better handled by syslog().

Update tinc(8) man page to:
1. state the implementation aligns with 1.0.36 of tinc.org;
2. use same hostname as mentioned in usage line.
Fix typos in tinc.c.
The '-m' flag was added to date largely
to support git scripts. It predates the
tmdate code, which is why it exists, but
it's a recent enough addition that nothing
I'm aware of uses it, other than git.
As a result, it would be good to remove
it, so let's do that.
As part of the transition to 64 bit userspace
APIs, we need to make our libc functions which
take arrays all accept and deal with large sizes.
This does the work for qsort.
According to the ASN.1 BER spec, we should be encoding
all sequences (including empty ones) as constructed:
8.9.1 The encoding of a sequence value shall be constructed.
8.10.1 The encoding of a sequence-of value shall be constructed.
8.11.1 The encoding of a set value shall be constructed.
8.12.1 The encoding of a set-of value shall be constructed.
However, we were only setting them as constructed when the
list was non-empty.
This changes it, and makes letsencrypt happy with the CSRs that
we generate.
when running 'mk clean', we get a stray
libpanel.$O.a, because our 'mk clean'
rule expects libpanel.a$O.
This causes build failures after mk clean
on a symbol change.

- avoid print() format routines (saves alot of code)
- avoid useless opens of /dev/cons (already done by initcode)
- avoid useless binds of /env and /dev (already done by initcode)
- do bind of /shr in bootrc, it is not needed by us
- we'r pid 1 so kernel will print the exit message for us
currently, git/fetch prints the refs
to update before it fully fetches the
pack files; this can lead to updates
to the refs before we're 100% certain
that the objects are present.
This change prints the updates after
the packfile has been successfully
indexed.
We used to use performance cycle counter for cycles(),
but it is kind of useless in userspace as each core
has its own counter and hence not comparable between
cores. Also, the cycle counter stops counting when
the cores are idle.
Most callers expect cycles() to return a high resolution
timestamp instead, so do the best we can do here
and enable the userspace generic timer virtual counter.
sbrk(0) returns the current end address of the BSS segment,
not the base. This might have been confused with the behaviour
of segbrk(), which when given a zero address returns the base.

When pulling into a git repository that is group
writable as a non-owner, the pack file is left
in place because we do not have permission to
remove it.
We also leave it behind if we bail out early due
to an error, or due to only listing the changes.
This pushes down the creation of the file, and
cleans it up on error.
thanks to Anthony Martin for spotting the bug.

we have to protect the temporary buffer allocated by rwfield()
as rwreg() calls amlmapio() which might cause further aml code
execution causing gc() which frees it under us (as it is not
referenced from the interpreter state).
this fixes a panic on boot of a
Lenovo Thinkpad P17 Gen1 Professional Mobile Workstation
when a virtio device gets reset, we have to also reset the device
shadow indices: availableidx and usedidx. for extra safetly,
we also reset the buffer descriptor table addresses.
this is accomplished by adding a vioqreset(VIOQueue*) function
that brings the queue to its initial reset state.
this fixes non functional ethernet after reboot(8).
The new interface uses pci capability structures to locate the
registers in a rather fine granular way making it more complicated
as they can be located anywhere in any pci bar at any offset.
As far as i can see, qemu (6.0.50) never uses i/o bars in
non-legacy mode, so only mmio is implemented for now.
The previous virtio drivers implemented the legacy interface only
which uses i/o ports for all register accesses. This is still
the preferred method (and also qemu default) as it is easier to
emulate and most likely faster.
However, some vps providers like vultr force the legacy interface
to disabled with qemu -device option "disable-legacy=on" resulting
on a system without a disk and ethernet.
This used to be a internal function, but virtio
uses multiple structures with the same cap type
to indicate the location of various register
blocks in the pci bars so export it.
fn foo @{bar} is now equivalent to
fn foo {@{bar}}. As a side effect,
this disallows creating functions
named after keywords without first
quoting them.
We need a way to parse a rsa certificate request and return the public
key and subject names. The new function X509reqtoRSApub() works the
same way as X509toRSApub() but on a certificate request.
We also need to support certificates that are valid for multiple domain
names (as tlshand does not support certificate selection). For this
reason, a comma separated list is returned as the certificate subject,
making it symmetric to X509rsareq() handling.
A little helper is provided with this change (auth/x5092pub) that takes
a certificate (or a certificate request when -r flag is provided) and
outputs the RSA public key in plan 9 format appended with the subject
attribute.
git/export *almost* produces output that can be
emailed with upas using
git/export $commit | mail maintainer@site.com
but, the
From: commit-id date
line that git generates trips it up. Luckily,
'git am' doesn't seem to care much if that line
is missing, so we can simply omit it with no issue.
There are a number of alphabets in common use for base32
and base64 encoding, such as url-safe encodings.
This adds support for passing a function to encode into
arbitary alphabets.

When resizing windows, vt would signal ssh by updating
the window size and sending an interrupt. Ssh reacted
by forwarding both the winch and an interrupt.
This change adds a WINCH generation counter so that
ssh can differentiate between resizes and interrupts.
If an interrupt comes in, and the WINCH generation
changes, then the interrupt is taken as signalling a
WINCH.
The change to "assignment not used" breaks symmetry with
"used and not set" and removes the reference to the
specific warning mentioned in /sys/doc/comp.ms.
Also, the patch was half-assed as that it left some typos
in like "used an not set", which this change also fixed.
We weren't correctly skipping the location operators
in codefree. This would mostly be work, but sometimes
you'd get unlucky and have one of the argmuents mismatch,
and that would lead to an invalid free.
This correctly skips the args in codefree.
Since we now store /dist/plan9front in git, the
initial assumption that the owner of the repo
is the person touching it is not always true.
This change gives us a better heuristic for the
file permissions we should have in the files we
copy around, basing it off of the permissions of
the .git directory.
When loading a file using ".", we could
end up with our line numbers thrown off
due to the mutation of lexline. Putting
lexline into the runq beside the file
that we're reading from causes it to get
pushed and popped correctly, so that we
no longer lose track of our location.
when trying to request certificates from letsencrypt,
their test api would reject our csr because of
"tuncated sequence" unless we force subectAltName
by passing multiple domains (as comma separated list).
apparently, we need to provide the context specific tag
"cont [ 0 ]" for the extensions even when we do have
any extensions for the csr (triggered when we need to
have subjectAltNames).
for this, we change mkcont() to take a Elist* instead,
which then can be nil when not used. also put the tag
number argument first, which makes it easier to read.
As checking for all zero has to be done in a timing-safe
way to avoid a side channel, it is best todo this here
instead of letting the caller deal with it.
This adds a return type of int to curve25519_dh_finish()
where returning 0 means we got a all zero shared key.
RFC7748 states:
The check for the all-zero value results from the fact
that the X25519 function produces that value if it
operates on an input corresponding to a point with small
order, where the order divides the cofactor of the curve.
1. add the curve x25519 to tls, both client and server.
it's more faster, immune to timing attacks by design,
does not require verifying if the public key is valid,
etc etc. server-side has to check if the client supports
the curve, so a new function has been introduced to parse
the client's extensions.
2. reject weak dhe primes that can be easily cracked with
the number field sieve algorithm. this avoids attacks like
logjam.
3. stop putting unix time to the first 4 bytes of client/
server random. it can allow fingerprinting, tls 1.3 doesn't
recommend it any more and there was a draft to deprecate
this behaviour earlier.[1]
4. simply prf code, remove useless cipher enums.

Note how the days (i.e. ' M Tu W Th F Sa Su') for Feb and Mar
do not align with the day numbers.
This is because an extra space is left *before* adding the terminating
'\0' via the pointer `dayw`.
With the patch applied the calendar aligns nicely for the year view:

When switching a branch implicitly -- ie, creating a local
branch off of a remote branch -- we would get the list of
changed files before we would resolve the implicit branch
switch, leading to an empty list of changes.
All of these files appear to have been imported from sources in a
case-insensitive manner and consequently lost their original content.
- Hx, Hb, and Hi fonts should be narrow versions of Helvetica
- c[1-3] fonts should be condensed versions of Century Old Style
- the lH character should be a filled left hand symbol
- the rh character should be a stroked right hand symbol
- the rc character should be the right ceiling symbol
I've verified that these are the only files that collide with others
when ignoring case (aside from rc/bin/[Kk]ill but those are correct).
git/import expected a patch, however upas/fs serves
either a raw file without any of the mime decoding
and line joining, or a directory, with the headers
and body split out.
This makes it a pain to apply some mails.
So, here we teach git to import upas dirs natively,
making it easy to handle all patches that come in
as emails.
git/push died within a subshell, which prevented the
whole program from exiting, and lead to an incorrect
ref update line that confused people.
git/send would eventually error out, but would push
all the data before that happened; this was annoying.
It's not fatal for someone else to push a branch
with objects that we don't have. We should deal
with it gracefully, and act as though it doesn't
exist.
In showlist, call bwindata instead of bwinopen in order to use a
pre-existing fd to write to the data file. This existing fd will
properly honour any address set by a previous write to the addr file.
Specifically, the redraw function sets addr to "," before calling
showlist in order to overwrite the entire contents of the window.
This is implemented by checking first if the uri is
a directory containing the .git/ subdirectory.
If this is the case, we fork git/serve serving the
repository on a pipe.
We weren't giving all objects to the twixt() function, and
it was making bad life choices -- gambling, smoking, drinking,
and packing in too much data.
With more information, it doesn't do the last.
For 64-bit architectures, the a.out header has the HDR_MAGIC flag set
in the magic and is expanded by 8 bytes containing the 64-bit virtual
address of the programs entry point. While Exec.entry contains physical
address for kernel images.
Our sysexec() would always use Exec.entry, even for 64-bit a.out binaries,
which worked because PADDR(entry) == entry for userspace pointers.
This change fixes it, having the kernel use the 64-bit entry point
and document the behaviour in the manpage.
The 9p debug server was broken as it assumed the first
tree file added would have a qid of 0 (it has a qid
of 1 as the root directory is using 0 already).
Instead, just compare File* pointers and get rid of
the table (less code).
When passing 64-bit unsigned addresses as 64-bit signed
file offsets, we have to make sure to not pass negative
offsets (filtered out by kernel and lib9p)!
This is solved by clearing and sign bit in encoding and
63-bit sign extension on decoding.
Make the mem file writable (needed for acid).
The 9p debug server provided a single directory containing
mem and regs files. This patch renames the regs file
(which is in vmx specific text format) to "xregs" and
adds "regs" and "kregs" file which use the same format
as exported by the kernels /proc filesystem.
This allows one to bind the vmx directory over a proc
directory and attach acid to a running system like:
mount -b /srv/vmx /proc/1
acid -k -lkernel 1 /sys/src/9/pc64/9pc64
If we tokenize the register file contents in a static buffer,
we can avoid having to duplicate the register names.
All callers to rpoke() provide constant register arguments
so they also do not need to be duplicated.
games/dmid uses the same sample rate as the chip for music, but other
applications do not. opl3 and its older version opl2 (not in 9front)
read an input stream of commands in basically IMF format, something
used in other id Software games and some others, which assumes a
given input sampling rate: 700 Hz for Wolfenstein 3D music, 560 Hz
for Commander Keen, 60 Hz for Ultima 6, etc.
The opl3 emulation on the other hand is not really intended to run at
a sampling rate different that the chip's 49.716 kHz sampling rate.
Previously, we assumed it runs at 44.1 kHz and just used the input
rate as a divisor to get the number of samples per delay tic.
From what I understand, the correct way to use it for accurate
emulation is to run the opl chip emulator at its intended sampling
frequency, then downsample to 44.1 kHz. This means better output
but more code. The alternative is to basically do the same as
before rev 8433, except with no buffering, but at accuracy/quality
loss. This change implements the former and just forks pcmconv to
deal with resampling.
Now that we have these new functions,
we can also make them return an error
instead of calling sysfatal() like
postmountsrv().
Remove the confusing Srv.srvfd, as it
is only temporarily used and return
it from postsrv() instead.
To use srvrease()/srvaquire() we need to have a way to spawn
new processes to handle the service loop. This functionality
was provided by the internal _forker() function which was
eigther rfork or libthread based implementation depending on
if postmountsrv() or threadpostmountsrv() where called.
For servers who want to use srv() directly, _forker would not
be initialized so srvrelease() could not be used.
To untangle this, we get rid of the global _forker handler
and put the handler in the Srv structure. Which will get
initialized (when nil) to eigther srvforker() or threadsrvforker()
depending on if the thread or non-thread entry points where used.
For symmetry, we provde new threadsrv() and threadpostsrv()
functions which handle the default initialization of Srv.forker.
This also allows a user to provide his own forker function,
maybe to conserve stack space.
To avoid dead code, we put each of these function in their
own object file. Note, this also allows a user to define its
own srvforker() symbol.
this fixes real-time applications.
-n previously specified a rate divisor rather than the rate itself,
which was used for specific applications outside of 9front. instead,
just set the rate directly, more useful and straightforward.
Remove unused fields and factor common fields into a
new PMach struct in port/portdat.h.
The fields machno, splpc and proc are not moved to
PMach as they are part of the known offsets from
assembly (l.s).
Resample is well known for taking a long time to resize an image. This
patch brings an important performance boost (in my test image, time
was reduced from ~2850ms to ~500ms). It does that by extracting FP
multiplication and division out of the innermost loop of
resamplex/resampley.
The results differ slightly from the current implementation: in my
test: ~0.3% of the bytes had a ±2 difference in their value, which I
attribute to rounding errors. I'm personally not concerned with that
deviation, given the performance gains. However, I recommend testing
it just to be sure I didn't overlook anything.

The patch does the following:
1. Adds recognition of executable script (shebang) files.
2. Returns correct MIME type for mbox files (RFC 4155).
3. Returns XML instead of HTML type in some cases.

When an imap fetch fails, it's helpful at times to know the underlying
cause. This provides more details by providing the underlying error
message.
unlike other tools like iconv(1), a crop(1) without arguments or with
ones resulting in a no-op, like `-t 0 0', errors out. other options
like `-i 0' do not error. this breaks assumptions and results in
tedious intermediary steps or hacks like:
foo | {crop -t $1 $2 >[2]/null || cat} > baz.bit
instead, just ignore the check. subsequent code doesn't make
assumptions on that.
/sys/src/cmd/mksyslib uses `{basename $stem .$objtype}^.c to get the
source file name for *.acid files. /sys/lib/acid/thread expects
sched.$objtype.acid. This lets /sys/src/libthread/mkfile generate
that file.
