This changeset makes it possible to build the Second Life viewer using
Python 3. It is designed to be used with an equivalent Autobuild branch
so that a developer can compile without needing Python 2 on their
machine.
Breaking change: Python 2 support ending
Rather than supporting two versions of Python, including one that was
discontinued at the beginning of the year, this branch focuses on
pouring future effort into Python 3 only. As a result, scripts do not
need to be backwards compatible. This means that build environments,
be they on personal computers and on build agents, need to have a
compatible interpreter.
Notes
- SLVersionChecker will still use Python 2 on macOS
- Fixed the message template url used by template_verifier.py

Turns out that one of our WorkQueue integration tests was relying on the
incorrect runFor() behavior that we just fixed, so the test broke. Now that
runFor() doesn't wait around for work to be posted, use an explicit wait loop
instead.
To support this, add LLCond::get(functor), where functor must accept a const
reference to the stored data. This new get() returns whatever the functor
returns, allowing a caller to peek at the stored data.
Also use universal references for all remaining LLCond functor arguments.

Reverting a merge is sticky: it tells git you never want to see that branch
again. Merging the DRTVWR-546 branch, which contained the revert, into the
glthread branch undid much of the development work on that branch. To restore
it we must revert the revert.
This reverts commit 029b41c0419e975bbb28454538b46dc69ce5d2ba.

runFor(interval) and runUntil(timestamp) are intended, and documented, to run
*no longer than* the specified time. Instead, the initial implementation
always waited the full specified time, hoping for work to arrive. Fix that:
once we clear work that's already pending, return right away.

It's sometimes important to finish other initialization before launching the
threads in the ThreadPool, so make that an explicit step. In particular, we
were launching the LLImageGL texture thread before initializing the GL
context, resulting in all gray textures.

and correspondingly, ll_convert<std::wstring>(const wchar_t*).
Now that we're using ll_convert() for single-argument stringize(arg), make
sure it can efficiently handle the simple case of constructing a string from a
const char pointer.

It's useful to be able to say STRINGIZE(item0 << item1 << item2), and we use
that a lot in our code base. But weird syntax aside, there are a couple
advantages to being able to write stringize(item0, item1, item2).
First, it allows stringize() to be used from within some other variadic
function, without having to make that function a macro that accepts an
arbitrary insertion-operator expression. There's no such thing as a member
macro.
Second, particularly for variadic functions, it allows us to optimize the
single-argument case stringize(item0). A macro can't do that. When item0 is
already a string of the desired char type, instead of streaming it into a
std::ostringstream and retrieving it again, we can simply return the input
string. When it's a pointer to the desired char type, we can directly
construct the result string without the help of std::ostringstream. When it's
a string of some other char type, we can engage ll_convert() to perform needed
conversions.
We generalize and optimize the generic gstringize() function, retaining the
role of stringize() and wstringize() as thin wrappers that merely provide the
desired char type.
Optimizing the single-argument case requires separately defining gstringize()
with two or more arguments: the general case. Then gstringize(arg) is
delegated to a gstringize_impl class template so we can partially specialize
to recognize a std::basic_string<desired_char_type> argument, as well as
desired_char_type*. Both these specializations engage ll_convert(), which
already handles the trivial case when no conversion is required.
Use of ll_convert() in this role supercedes and generalizes the previous
wstring_to_utf8str() and utf8str_to_wstring() overloads.
Also introduce stream_to(std::ostream&, ...) to support variadic streaming to
other destinations, e.g. a file, std::cout, ...

This reverts commit 5188a26a8521251dda07ac0140bb129f28417e49, reversing
changes made to 819088563e13f1d75e048311fbaf0df4a79b7e19.

We want to skip calling PostMessage() to bump the window thread out of
GetMessage() in any frame with no work functions pending for that thread. That
test depends on being able to sense the size() of the queue. Having converted
to WorkQueue, we need that queue to support size().

That is, when LLViewerFetchedTexture::scheduleCreateTexture() wants to call
createTexture() on the LLImageGLThread, but postCreateTexture() on the main
thread, use the "mainloop" WorkQueue to set up the handshake.
Give ThreadPool a public virtual run() method so a subclass can override with
desired behavior. This necessitates a virtual destructor. Add accessors for
embedded WorkQueue (for post calls), ThreadPool name and width (in threads).
Allow LLSimpleton::createInstance() to forward arguments to the subject
constructor.
Make LLImageGLThread an LLSimpleton - that abstraction didn't yet exist at the
time LLImageGLThread was coded. Also derive from ThreadPool rather than
LLThread. Make it a single-thread "pool" with a very large queue capacity.
|

Give ThreadPool and WorkQueue the ability to override default
ThreadSafeSchedule capacity.
Instantiate "mainloop" WorkQueue and "General" ThreadPool with very large
capacity because we never want to have to block trying to push to either.

postIfOpen() provides a no-exception alternative to post(), which blocks if
full but throws if closed. postIfOpen() likewise blocks if full, but returns
true if able to post and false if the queue was closed.

That function wants to pass a code_page to ll_convert_string_to_wide(), but
the code_page parameter was being mistaken for the length parameter, leading
to access violations.

clang allows us to specify, as a default function parameter, an expression
involving a preceding parameter, e.g. (char* ptr, size_t len=strlen(ptr)). The
Microsoft compiler produces errors, requiring more overloads to address that.
Also #undef llstring.h's declaration helper macros at the bottom of the file.
Once we've used them to declare stuff, they need not (should not) be visible
to the consuming source file.
