The compiler was deducing an unsigned type for the difference (U64 desired
microseconds - half KERNEL_SLEEP_INTERVAL_US). When the desired sleep was less
than that constant, the difference went hugely positive, resulting in a very
long snooze.
Amusingly, forcing that U64 result into an S32 num_sleep_intervals worked only
*because* of integer truncation: the high-order bits were discarded, resulting
in a negative result as intended.
Ensuring that both integer operands are signed at the outset, though, produces
a more formally correct result.

It seems newer compilers have a different interpretation of exactly when to
engage LLSDArray's copy constructor. In particular, this assignment:
some_LLSD_map[key] = LLSDArray(...)(...)...;
used to convert the LLSDArray object directly to LLSD; now it first calls the
custom copy constructor, which embeds the intended array within an outer array
before assigning it into the containing map.
The newer llsd::array() function avoids that problem because what it returns
is already an LLSD object.
Taking inventory of LLSDArray assignments of that form turned up a number of
workarounds like LLSD(LLSDArray(...)). Replacing those with llsd::array() is
both simpler and more readable.
Tip of the hat to Chorazinallen for surfacing this issue!

The unsigned index arithmetic was problematic in that case.

Since LLSDSerialize::SIZE_UNLIMITED is negative, passing that through unsigned
size_t parameters could result in peculiar behavior.

There might be other causes for sendRenderInfoToRegion and getRenderInfoFromRegion, crashing, but in some cases viewer was shutting down

LLViewerTexture::mNeedsCreateTexture needs to be an attomic bool since
it is written both in the main thread and in the GL image worker thread.
We can now enable threaded bump maps creation as a result of this fix.

Introduce LLSD template constructors and assignment operators to disambiguate
construction or assignment from any integer type to Integer, likewise any
floating point type to Real. Use new narrow() function to validate
conversions.
For LLSD method parameters converted from LLSD::Integer to size_t, where the
method previously checked for a negative argument, make it now check for
size_t converted from negative: in other words, more than S32_MAX. The risk of
having a parameter forced from negative to unsigned exceeds the risk of a
valid length or index over that max.
In lltracerecording.cpp's PeriodicRecording, now that mCurPeriod and
mNumRecordedPeriods are size_t instead of S32, defend against subtracting 1
from 0.
Use narrow() to validate newly-introduced narrowing conversions.
Make llclamp() return the type of the raw input value, even if the types of
the boundary values differ.
std::ostream::tellp() no longer returns a value we can directly report as a
number. Cast to U64.

'BeqJanus/ll-viewer-pull-requests/Beq-alpha-mask-on-emissive-fix' into DRTVWR-570-maint-Q
|
|
|
|
This is the most local fix for this issue, addressing the specific unqualified use of HAS_ALPHA_MASK.
If we find other issues with alpha mask being applied incorrectly then, it may be better to fix higher up in llvieweshadermgr.cpp by reverting the changes from SL-17532.
For now, this way works for this specific bug without non-emissive side-effects.

llssize is for a function parameter that should accept a size or index
(derived from size_t, which is 64 bits in a 64-bit viewer) but might need to
go negative for flag values. We've historically used S32 for that purpose, but
Xcode 14.1 complains about trying to pass size_t to S32.
narrow() is a template function that casts a wider type (e.g. size_t or
llssize) to a narrower type (e.g. S32 or U32), with validation in
RelWithDebInfo builds. It verifies (using assert()) that the value being
truncated can in fact fit into the target type.

Due to udp texture fetching no longer being present
|
|
|
|
|
|
It's a little distressing how often we have historically coded S32 or U32 to
pass a length or index.
There are more such assumptions in other viewer subdirectories, but this is a
start.

Or rather, attempting to implicitly sign. On TeamCity we must explicitly sign
using viewer_manifest.py. On a developer system, without these changes, Xcode
produces many errors of the form:
error: An empty identity is not valid when signing a binary for the product
type 'Command-line Tool'. (in target 'INTEGRATION_TEST_lldir' from project
'SecondLife')
and refuses to compile anything at all.
Thanks to Rye Mutt and NickyD. Also thanks Geir Nøklebye for additional
settings to help tame Xcode 14.1 warnings.
