c78368f04f Change the interface for fatal logging.
This more general interface lets liblog give us any fatal log message,
regardless of source. This means we can remove the special case for
LOG_ALWAYS_FATAL with a simpler scheme that automatically works for
the VM too.

7c435f2415 Leave more space for extensions in pthread_rwlockattr_t
Change pthread_rwlockattr_t from int to long. On LP64 this gives us more
room for extensibility since longs are 8 bytes. glibc also reserves 8
bytes for this.

9a5a3e8e74 Fix <math.h> to quieten most of our warnings.
I've reported the wcsftime bug upstream, but we really just want to use -D
to ensure the buggy code isn't built. (I've also brought our strftime a bit
closer to upstream now we have the right define.)

I don't think upstream is likely to fix all their sign-compare and
uninitialized warnings, so let's just silence them.

As for libm, again upstream isn't likely to fix all their warnings, and
silencing those made the ones that were our fault stand out. I've fixed
our <math.h> to fix the warnings caused by our lack of definitions for
the non-imprecise long-double functions. I checked the C99 standard, and
all these functions are there.

9ded07cff6 bionic: make epoll_event structure packed
Description: In the kernel the epoll_event structure is packed
in 64 bit kernel builds to allow the structure to be more easily
compatible with 32 bit user space.  As a result, when user space
is 64-bit the structure must be packed as well.

Add unit test to show the ptr alignment issue.

f0291ca6b7 Merge "Switch to a working UTF-8 mb/wc implementation." 2014-05-01 23:12:41 +00:00
Elliott Hughes
5a0aa3dee2 Switch to a working UTF-8 mb/wc implementation.
Although glibc gets by with an 8-byte mbstate_t, OpenBSD uses 12 bytes (of
the 128 bytes it reserves!).

We can actually implement UTF-8 encoding/decoding with a 0-byte mbstate_t
which means we can make things work on LP32 too, as long as we accept the
limitation that the caller needs to present us with a complete sequence
before we'll process it.

Our behavior is fine when going from characters to bytes; we just
update the source wchar_t** to say how far through the input we got.

I'll come back and use the 4 bytes we do have to cope with byte sequences
split across multiple input buffers. The fact that we don't support
UTF-8 sequences longer than 4 bytes plus the fact that the first byte of
a UTF-8 sequence encodes the length means we shouldn't need the other
fields OpenBSD used (at the cost of some recomputation in cases where a
sequence is split across buffers).

This patch also makes the minimal changes necessary to setlocale(3) to
make us behave like glibc when an app requests UTF-8. (The difference
being that our "C" locale is the same as our "C.UTF-8" locale.)

fddbafdc0a Keep the kernel header scrubber's data structures in sync.
If you rewrite the tokens of a #if you need to rewrite the expression to match
because either might be used later. This was showing up as SIGRTMAX being
rewritten in a #define but not in the #ifndef that guarded it, for which case
I've added a unit test.

0990d4fda8 Make SIGRTMIN hide the real-time signals we use internally.
__SIGRTMIN will continue to tell the truth. This matches glibc's
behavior (as evidenced by the fact that we don't need a special case
in the strsignal test now).

3d7a0d9b08 Switch to the OpenBSD wcsto* functions.
This replaces a partial set of non-functional functions with a complete
set of functions, all of which actually work.

This requires us to implement mbsnrtowcs and wcsnrtombs which completes
the set of what we need for libc++.

The mbsnrtowcs is basically a copy & paste of wcsnrtombs, but I'm going
to go straight to looking at using the OpenBSD UTF-8 implementation rather
than keep polishing our home-grown turd.

(This patch also opportunistically switches us over to upstream btowc,
mbrlen, and wctob, since they're all trivially expressed in terms of
other functions.)

533dde4dbf Fix brk/sbrk error checking.
Note that the kernel returns the current break on error or if the requested
break is smaller than the minimum break, or the new break. I don't know where
we got the idea that the kernel could return -1.

Also optimizes the query case.

Also hides an accidentally-exported symbol for LP64.
