Iterators shouldn't have methods like write(); if you need to write to
an iterator, that logic should be handled by something outside of the
iterator...which also explains why we have a specialization of
nsCharTraits<nsWritingIterator<T>>. The HTML parser wants this for its
own reasons, so we have to make sure it continues to work.
This change is necessary so we can start using a pair of
iterators (current, end) and subtract them to figure out how far we have
left to go. The current code just uses size_forward and size_backward
for this purpose, and it's quite an unusual iterator that knows how far
it can go until it's done.
Asking for size_forward on an iterator that you haven't started reading
from is just asking for the length of the original string, so use that
instead.
This adds an SSE2 optimized path for UTF-16 strings that can be trivially
converted to UTF-8 (they contain no characters > 0X7F). It has a
speedup for the case where many of the leading characters are < 0X80 and
should have the same performance in the worst-case scenario where the first
character is > 0X7F.
This removes the unnecessary setting of c-basic-offset from all
python-mode files.
This was automatically generated using
perl -pi -e 's/; *c-basic-offset: *[0-9]+//'
... on the affected files.
The bulk of these files are moz.build files but there a few others as
well.

It's an annotation that is used a lot, and should be used even more, so a
shorter name is better.

StringBeginsWith (resp. StringEndsWith) takes a defaulted
nsStringComparator object for doing comparisons. The flexibility this
affords is great, but the cost is not: nsStringComparator has virtual
methods, so initializing that defaulted object (at every callsite)
requires a temporary object whose vtable must be initialized.
Since the overwhemingly common case is to use the default comparator
anyway, we should not use defaulted arguments and instead provide the
default comparator/user-provided comparator cases as separate overloads.
This change eliminates the virtual call for the majority of callsites
and reduces codesize as well.
The patch changes all uses of SizeOfIncludingThisMustBeUnshared() to
SizeOfIncludingThisIfUnshared(). This incurs the (tiny) cost of an unnecessary
IsReadonly() check for guaranteed-unshared strings, but avoids the possible
assertion failures that would occur when MustBeUnshared() was used incorrectly
on shared strings, which is an easy mistake to make.

Also, use a fatal assertion in
nsStringBuffer::SizeOfIncludingThisMustBeUnshared().

The patch removes 455 occurrences of FAIL_ON_WARNINGS from moz.build files, and
adds 78 instances of ALLOW_COMPILER_WARNINGS. About half of those 78 are in
code we control and which should be removable with a little effort.

They are kept around for the sake of the standalone glue, which is used
for e.g. webapprt, which doesn't have direct access to jemalloc, and thus
still needs a wrapper to go through the xpcom function list and get to
jemalloc from there.
We have better, C++-ier ways of doing compile-time assertions now. Fold in the
nsTSubstring.cpp change in passing, since mccr8 suggested it in his review.
