Remove svn:mergeinfo from the releng/10.0 branch.

After branch creation from stable/10, the stable/10 branch mergeinfo
was moved to the root of the branch.

Since there have not been any merges from stable/10 to releng/10.0
yet, we do not need to track any of the existing mergeinfo here.

Merges to releng/10.0 should now be done to the root of the branch.

For future branches during the release cycle, unless otherwise noted,
this change will be done as part of the stable/ and releng/ branch
creation.

Compile contrib/tzcode/stdtime/localtime.c with -fwrapv, since it relies
on signed integer overflow wrapping. Otherwise mktime(3) and timegm(3)
can hang, in case the timestamp passed in struct tm is not representable
in a time_t. Specifically, any timestamp after 2038-01-19 03:14:07, in
combination with a 32-bit time_t.

Note that it would be better to change the code to not rely on undefined
behaviour, but it is contributed code, and it is not entirely trivial to
fix the issue properly.

With retirement of cpumask_t and usage of cpuset_t for representing a
mask of CPUs, pc_other_cpus and pc_cpumask become highly inefficient.

Remove them and replace their usage with custom pc_cpuid magic (as,
atm, pc_cpumask can be easilly represented by (1 << pc_cpuid) and
pc_other_cpus by (all_cpus & ~(1 << pc_cpuid))).

This change is not targeted for MFC because of struct pcpu members
removal and dependency by cpumask_t retirement.

etire the cpumask_t type and replace it with cpuset_t usage.

This is intended to fix the bug where cpu mask objects are
capped to 32. MAXCPU, then, can now arbitrarely bumped to whatever
value. Anyway, as long as several structures in the kernel are
statically allocated and sized as MAXCPU, it is suggested to keep it
as low as possible for the time being.

Technical notes on this commit itself:
- More functions to handle with cpuset_t objects are introduced.
The most notable are cpusetobj_ffs() (which calculates a ffs(3)
for a cpuset_t object), cpusetobj_strprint() (which prepares a string
representing a cpuset_t object) and cpusetobj_strscan() (which
creates a valid cpuset_t starting from a string representation).
- pc_cpumask and pc_other_cpus are target to be removed soon.
With the moving from cpumask_t to cpuset_t they are now inefficient
and not really useful. Anyway, for the time being, please note that
access to pcpu datas is protected by sched_pin() in order to avoid
migrating the CPU while reading more than one (possible) word
- Please note that size of cpuset_t objects may differ between kernel
and userland. While this is not directly related to the patch itself,
it is good to understand that concept and possibly use the patch
as a reference on how to deal with cpuset_t objects in userland, when
accessing kernland members.
- KTR_CPUMASK is changed and now is represented through a string, to be
set as the example reported in NOTES.

Please additively note that no MAXCPU is bumped in this patch, but
private testing has been done until to MAXCPU=128 on a real 8x8x2(htt)
machine (amd64).

Please note that the FreeBSD version is not yet bumped because of
the upcoming pcpu changes. However, note that this patch is not
targeted for MFC.

People to thank for the time spent on this patch:

several revision of the patches and really helped in improving
stability of this work.

Merger of the quota64 project into head.

This joint work of Dag-Erling Smørgrav and myself updates the
FFS quota system to support both traditional 32-bit and new 64-bit
quotas (for those of you who want to put 2+Tb quotas on your users).

By default quotas are not compiled into the kernel. To include them
in your kernel configuration you need to specify:

options QUOTA # Enable FFS quotas

If you are already running with the current 32-bit quotas, they
should continue to work just as they have in the past. If you
wish to convert to using 64-bit quotas, use `quotacheck -c 64';
if you wish to revert from 64-bit quotas back to 32-bit quotas,
use `quotacheck -c 32'.

There is a new library of functions to simplify the use of the
quota system, do `man quotafile' for details. If your application
is currently using the quotactl(2), it is highly recommended that
you convert your application to use the quotafile interface.
Note that existing binaries will continue to work.

Special thanks to John Kozubik of rsync.net for getting me
interested in pursuing 64-bit quota support and for funding
part of my development time on this project.

struct tm.tm_year is listed as 'years since 1900', and is signed. On
64 bit systems, years roughly -2^31 through 2^31 can be represented in
time_t without any trouble. 32 bit time_t systems only range from
roughly 1902 through 2038. As a consequence, none of the date munging
code for all the various calendar tweaks before then is present. There
are other problems including the fact that there was no 'year zero' and
so on. So rather than get excited about trying to figure out when the
calendar jumped by two weeks etc, simply disallow negative (ie: prior to
1900) years.

This happens to have an important side effect. If you bzero a 'struct
tm', it corresponds to 'Jan 0, 1900, 00:00 GMT'. This happens to be
representable (after canonification) in 64 bit time_t space. Zero tm
structs are generally an error and mktime normally returns -1 for them.
Interestingly, it tries to canonify the 'jan 0' to 'dec 31, 1899', ie:
year -1. This conveniently trips the negative year test above, which
means we can trivially detect the null 'tm' struct.

This actually tripped up code at work. :-/ (Don't ask)

Do not guarantee an overflow of tm_year when doing the binary search in
localtime/mktime/tmcomp and friends on ia64.

Approved by: re

Replace rev 1.33 with a real fix. The problem was integer overflows
when trying to store the year in a signed int. The maximum time_t on ia64
is around 292 billion years in the future, but 'int' and struct tm.tm_year
can only represent then ext 2.1 billion years or so.

This solves the problem of mktime/localtime looping on ia64. Unfortunately,
the standards say that tm_year is an 'int', so we are still stuck with a
y2147483647 bug. bash2's configure script looks for bugs in mktime() and
fails on ia64 because of this. However, mktime() on FreeBSD fails the test
normally anyway so this is no big loss.

This change does not affect any other platforms besides ia64.

excessive usage of the 'const' qualifier that was neither
present in the prototype in the publice header, nor in the
local prototype just above the function definition.
- Replace the K&R function definition with a ANSI-C one.
- Update the prototype of strftime(3) in its manual page.

function prototype and definition of strptime(3).
- Update the manual page.

Add routines to convert time_t to/from fixed-bit fields. These routines
serve two purposes: (1) so we can maintain backwards compatibility with
protocols (rwhod, dump, etc...) that either assume time_t is 32 bits or
assume sizeof(time_t) == sizeof(int), or make other similar assumptions.
(2) To tag such routines (by the presence of these calls) for future
cleanup/extension work.

The 32->64 routine, time32_to_time() (when time_t is 64 bits, that is),
is defined specifically to implement temporal locality to properly set the
msb bits of a 64 bit time_t quantity, using the 50 year rule. The locality
code has not been implemented yet (and doesn't need to be for a while),
but that is the intent. This will allow us to maintain backwards protocol
compatibility past 2038.

These routines are intended to be platform and time_t agnostic.

Add unsigned char cast to isupper

Implement new format specifier for strftime: %OB, alternative national
representation of the full month name. In the Russian locale, this alternative
will be "nominative case", useful when the date designate month as a whole.
E.g. month heading in a calendar. I hope it can be useful for some other
locales too.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

When attempting to load a `lastditch' timezone (e.g., because the load
of the user's timezone failed), don't bail if the specified timezone
doesn't have an offset; in this case it isn't going to. (Perhaps it would
be better to change the caller to always supply one, but this is quick
and clean and fixes the bug in the easiest possible way.)

Here are the diffs for libc_r to get it one step closer to P1003.1c
These make most of the thread/mutex/condvar structures opaque to the
user. There are three functions which have been renamed with _np
suffixes because they are extensions to P1003.1c (I did them for JAVA,
which needs to suspend/resume threads and also start threads suspended).

I've created a new header (pthread_np.h) for the non-POSIX stuff.

The egrep tags stuff in /usr/src/lib/libc_r/Makefile that I uncommented
doesn't work. I think its best to delete it. I don't think libc_r needs
tags anyway, 'cause most of the source is in libc which does have tags.

also:

Here's the first batch of man pages for the thread functions.
The diff to /usr/src/lib/libc_r/Makefile removes some stuff that was
inherited from /usr/src/lib/libc/Makefile that should only be done with
libc.

also:

I should have sent this diff with the pthread(3) man page.
It allows people to type

make -DWANT_LIBC_R world

to get libc_r built with the rest of the world. I put this in the
pthread(3) man page. The default is still not to build libc_r.


also:
The diff attached adds a pthread(3) man page to /usr/src/share/man/man3.
The idea is that without libc_r installed, this man page will give people
enough info to know that they have to build libc_r.

Revert to old version of strftime.c; the new one doesn't work right.

Merge the recently-imported tzcode96h distribution (libc portion). The

Don't reset LC_TIME to C when it isn't neccessary

Fix manpage to reflect current sources

Restore %s format support from previous version

Fix default %c to be ctime-compatible as supposed (by Solaris too)

The European Commission went out and invented a new sort of summer-time
changeover, so we have to extend the format of timezone files (in a backward-
compatible way, of course). This probably means that libc needs a minor
version number bump before 2.2 is released (or maybe not).

Implement locale-sensitive strftime () from ADO (heavily modified
by me). This probably loses for multibyte characters, but I have no
way of telling. I'll let ache decide whether to add this support to
startup_setlocale. Note that for this to make any sense at all, the
symlinks in /usr/share/locale must go. (For the moment, this doesn't
make any difference since there are no locales supplied.)

Remove trailing whitespace.

On snap 950210, format %s (print seconds from the epoch) is missing
from the code in strftime.c . This affects both the library code
and all the commands using it (e.g. date +%s).

Note that %s is not required by ANSI, but we've already got it in 1.1.5.1.

Suggested by: luigi@labinfo.iet.unipi.it (Luigi Rizzo)

Use latest Arthur Olson timezone code rather than that supplied with
4.4. The code is almost identical to the 4.4 versions, but this organization
should make it easier to merge new versions in the future.

Port to FreeBSD. Not ready for inclusion in libc just yet, but here
so we can compile zic.
