This upgrade also introduces exact stack rooting (see to the wiki:
JSRootingGuide) and fixes problems with moving GC. This allows us to
enable generational garbage collection (GGC).
Measurements a few months ago have shown a performance improvement of a
non-visual replay of around 13.5%. This probably varies quite a bit, but
it should be somewhere between 5-20%. Memory usage has also been
improved. Check the forum thread for details.
Thanks to everyone from the team who helped with this directly or
indirectly (review, finding and fixing issues, the required C++11
upgrade, the new autobuilder etc.)! Also thanks to the SpiderMonkey
developers who helped on the #jsapi channel or elsewhere!

This was SVN commit r16214.
Nobody ever looks at the data, and it takes up a lot of server disk
space. The feature should probably be restored in the future once we've
fixed all the obvious performance problems, since a wider range of data
lets us search for system-dependent issues (e.g. some GL drivers are
particularly slow with particular features), but it's not worthwhile
now.
This was SVN commit r16213.
The implementation on Windows was gross. The only user was CLogger,
which no longer uses it.
Also fix vswprintf_s to handle truncated output correctly (by returning
"") on Linux, now that CLogger is no longer relying on the buggy
behaviour.
This was SVN commit r16190.
Everything is char* now, so we don't need to mess around with different
string types.
Done with:
ag -ls 'LOG(MESSAGE|MESSAGERENDER|WARNING|ERROR)' source | xargs perl
-pi -e'1 while
s/(LOG(MESSAGE|MESSAGERENDER|WARNING|ERROR).*)%[hl]s/$1%s/g'
This was SVN commit r16187.
This saves the hassle of writing utf8_from_wstring(path.string()) in
places like log messages, and can be extended to better handle
non-ISO-8859-1 paths on Linux.
This was SVN commit r16185.
Done with:
ag -ls 'LOG(MESSAGE|MESSAGERENDER|WARNING|ERROR)' source | xargs sed
-i 's/LOG\(MESSAGE\|MESSAGERENDER\|WARNING\|ERROR\)(L/LOG\1(/g'
This was SVN commit r16183.
sys_vswprintf relies on platform-specific printf implementations, which
vary widely between platforms (in handling of truncation, return values,
use of %s/%S/%hs/%ls for mixing char and wchar_t strings, etc) and are
therefore a pain.
Use cppformat's fmt::sprintf instead, which has very similar syntax to
sprintf but is more C++ish and is portable.
Also, wchar_t is stupid, so use char* strings (which are expected to be
UTF-8) in CLogger. This creates a bit of a pain with changing all
callers to convert to char* strings, but that's their fault for not
using UTF-8 already.

This was SVN commit r16182.
Throwing exception on NULL is a bit extreme, and unhelpful when it
happens in rarely-tested error paths. Printing "(null)" is safer and
provides compatibility with glibc sprintf.
This was SVN commit r16180.
These cause a lot of type-safety trouble - unsupported types passed into
fmt::sprintf (like CStr or enums) will be accepted at compile time, but
trigger an exception at runtime. Remove them, so we'll get either an
implicit conversion to a supported type, or a compile-time error.
This was SVN commit r16179.
Also remove the placeholder technology and the rotary mill generic
Celtic template, and rename the rotary mill portrait. Refs #2619.
This was SVN commit r16174.
This needs to use the model-view matrix, not model-view-projection (the
transform uniform), else the axes won't be unit vectors and the particle
sizes will be wrong. But GLES doesn't have the pre-defined matrices, so
pass it in explicitly.
This was SVN commit r16165.
