Empty string test gone wrong.
Testing this requires that you have a locale that has the sign string
unset but has int_n_sign_posn set (the default locale falls through to
use "()" around negative numbers which is probably another bug).
I created that setup by hand and indeed without this fix negative
numbers are put out as positive numbers (doesn't fall through to use
"-" as default indicator).
Unfixed example in nl_NL.ISO8859-1 with lc->negative_sign set to empty
string:
strfmon(buf, sizeof(buf), "%-8i", -42.0);
==>
example2: 'EUR 42,00' 'Eu 42,00'
Fixed:
example2: 'EUR 42,00-' 'Eu 42,00-'
This file and suggested fix are identical in at least freebsd-8.
Backport might be appropriate but some expert on locales should
probably have a look at us defaulting to negative numbers in
parenthesis when LC_* is default. That doesn't look right and is not
what other OSes are doing.

a function. I made a mistake in assuming that the .cprestore directive
will cause the assembler to automatically restore 'gp' after the 'jalr'.
The .cprestore directive does its magic only after 'jal' and 'bal'
instructions - not the 'jalr'.

* Fix a race in chunk_dealloc_dss().
* Check for allocation failure before zeroing memory in base_calloc().
Merge enhancements from a divergent version of jemalloc:
* Convert thread-specific caching from magazines to an algorithm that is
more tunable, and implement incremental GC.
* Add support for medium size classes, [4KiB..32KiB], 2KiB apart by
default.
* Add dirty page tracking for pages within active small/medium object
runs. This allows malloc to track precisely which pages are in active
use, which makes dirty page purging more effective.
* Base maximum dirty page count on proportion of active memory.
* Use optional zeroing in arena_chunk_alloc() to avoid needless zeroing
of chunks. This is useful in the context of DSS allocation, since a
long-lived application may commonly recycle chunks.
* Increase the default chunk size from 1MiB to 4MiB.
Remove feature:
* Remove the dynamic rebalancing code, since thread caching reduces its
utility.
- Make sure the mode argument is either a character or a block device.
- Use S_IS*() instead of checking S_IF*-flags by hand.
- Don't use kern.devname when the argument is already NODEV.
- Always call snprintf with the proper amount of arguments corresponding
with the format.
- Perform some whitespace fixes. Tabs instead of 4 spaces, missing space
for return statement.
- Remove unneeded includes.
This first commit brings 3 functions for enumerating, retrieving,
adding, removing and modifying EFI variables. The immediate use of these
include the insertion of a new boot option as part of the installation
process.
This library uses ioctl(2) requests implemented by io(4) to pass the
requests down through the kernel to EFI. These ioctl requests are only
implemented on ia64, so libefi is currently only enabled on ia64. The
interface is generic and io(4) on mad64/i386 can easily be taught to
handle these once EFI support has been added to the kernel there.
When we had utmp(5), we had to list all the psuedo-terminals in ttys(5)
to make ttyslot(3) function properly. Now that pututxline(3) deals with
slot allocation internally (not based on TTY names), we don't need to
list all the TTYs on the system in ttys(5) to make user accounting work
properly.
This patch removes all the entries from the /etc/ttys files, but also
the pts(4) entries that were appended implicitly, which was added in
r154838.

Whincup (https), Jukka Ukkonen (if-modified-since) and Jean-François

Continuous catopen() calls cause 4 failig stat(2) each, which means a lot
of overhead. It is also a good idea to keep the opened catalogs in the memory
to speed up further catopen() calls to the same catalog since these catalogs
are not big at all. In this case, we count references and only free() the
allocated space when the reference count reaches 0. The reads and writes to
the cache are syncronized with an rwlock when these functions are called from
a threaded program.

I've noticed many applications do a bad job at timekeeping, for several
reasons:
- Applications like screen(1) don't update time records when restoring
the old user login record.
- Many applications only set ut_tv.tv_sec, not ut_tv.tv_usec.
This causes many problems for tools such as ac(8), which require the
timestamps to be properly ordered. This is why I've decided to let the
utmpx code obtain valid timestamps itself.
Instead of trying to reference-count them and free them as soon
as they are no longer needed, we now just keep them around and free
them all when we release the archive object. This fixes a number
of minor memory leaks, especially when reading damaged archives.
