mountable file descriptor, update documentation
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.

threadsrv() functions
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.

Fd2path is a useful call for the netsurf plan9 frontend,
so we should expose it.

inttypes.h was added to C99, and this is the only header that used
_SUSV2_SOURCE.
Also, remove now unneeded _SUSV2_SOURCE from python mkfile.

This patch exposes the bezierpts function,
providing a way to get the points on a path,
similar how bezsplinepts gives them for b
splines.

/$objtype/include/ape/math.h contained an almost
identical copy of math.h for each architecture.
The only difference between them architectures
was that some had an incorrect version of isinf
defined.
This change picks one of the versions of math.h
with a correct definition, moves it to /sys/include,
and removes the redundant versions.

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().
|
|
strndup is part of POSIX.1, so APE should provide it.
This patch adds it, so need to patch it out of fewer
programs going forward.
|
|
This allows us to attach additional context
to the biobuf so can read from some sort of
data structure without a global variable.
|
|
Fix missing 'L' in the size suffix, so we were overflowing the
maximum size.
|
|
Our ctype.h mistakenly ommitted isblank. Add it in.
While we're here, the make the 'isfoo()' functions
are broken: they're offsetting into the array, and
don't work with negative character values.
Sync the function bodies with the macros, and make
them produce correct results.
|
|
The putc macro is specified as returning an int, but our
type conversion rules turned it into a uint. Put in the
appropriate cast to make the type what we want.
|
|
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.

|
Masking with _IO_CHMASK after the assignment causes a warning.
We're better off masking before, but casting the assignment to
prevent sign extension.
|
|
When calling putc, we need to return either EOF
or the character returned. To distinguish the
two, we need to avoid sign extending 0xff. The
code attempted to do this, but the order of
operations was wrong, so we ended up masking,
setting a character, and then sign extending
the character.
This fixes things so we mask after assignment.

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.

This adds the mkfiles and plumb.h to ape,
similar to how libdraw is made available.
This is used for ports such as netsurf.
|
|
in accordance with c99:7.16. Used by perl, trivial enough
that I feel ok with adding it before the port is fully done.
|
|
We're missing type flags for:
hh: char
ll: vlong
z: size_t
t: ptrdiff_t
j: intmax_t
The lack of '%lld' was causing us to fail when parsing
timezone files. This brings us in line with the specifiers
in the C99 standard, section 7.19.6.2p11
|
|
C99 requires that if intXX_t types are defined, int_fastxx_t and
int_leastxx_t types are defined as well. We define all three to
be identical (intXX_t == int_fastXX_t == int_leastXX_t).
|
|
This makes it easier to figure out what's going wrong when
we forget to define _POSIX_SOURCE.
|
|
|
|
|
|
while technically a 32 bit ptrdiff_t is in spec on
systems with 64 bit ponters as long as we guarantee
that individual objects are small enough, this can
confuse legitimate code, so lets fix this.

postfd() and sharefd() functions
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.
|
|
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.

manpage
|
|
It's been 20 years since c99 came out. By now, if code
hasn't been fixed, it's not going to be. Requiring this
define just confuses porters.

I needed to convert the RSA private key that was laying around in
secstore into a format understood by UNIX® tools like SSH.
With asn12rsa(8) we can go from the ASN.1/DER to Plan 9 format, but not
back - so I wrote the libsec function asn1encodeRSApriv(2) and used it in
rsa2asn1(8) by adding the -a flag which causes the full private key to be
encoded and output.

moving _IO_CHMASK masking on the right hand side fixes it.
|
|
Now, you can safely use them in unbraced if statements, and
with char*s.

between being commited to a machno and having acquired the lock, the
scheduler could come in an schedule us on a different processor. the
solution is to have dtmachlock() take a special -1 argument to mean
"current mach" and return the actual mach number after the lock has
been acquired and interrupts being disabled.

we want to accept V4 subnets in CIDR notation consistently which
means we need to interpret the mask in context of the IP address.
so parseipmask() now has an additional v4 flag argument which
offsets the prefixlength by 96 so a /24 will be interpreted
as a /120.
parseipandmask() is the new function which handles this automatically
depending on the ip address type.
v4parsecidr() is now obsolete.
