Karl Williamson [Thu, 17 Dec 2015 17:22:44 +0000 (10:22 -0700)]
Optimize some qr/[...]/ classes

Bracketed character classes generally generate an ANYOF-type regnode,
which consists of a bitmap for the lower code points, and an inversion
list or swash to handle ones not in the bitmap.  They take up more
memory than other regnode types.  There are already some optimizations
that use a smaller and/or faster regnode instead.  For example, some
people prefer not to use a backslash to escape metacharacters, instead
writing something like /abc[.]def/.  This has for some time generated
the same thing as /abc\.def/ does, namely a single EXACT node, which is
both smaller and faster than an ANYOF node in the middle of two EXACT
nodes.

This commit adds some optimizations that hadn't been done previously.
Now things like /[\p{Word}]/ will optimize to \w, for example.  I had
not done this before, because my tests had shown very little performance
difference, but I had added most of the code to regcomp.c so it wouldn't
get lost, #ifdef'd out.

It turns out that I hadn't tested on code points above the bitmap, which
with this commit have a small, but appreciable speed up in matching, so
this commit enables and finishes that code.

Prior to this commit, things like /[[:word:]]/ were optimized to \w, but
things like /[_[:word:]]/ were not.  This commit fixes that.

regcomp.c: Try simplifications in some qr/[...]/d

Characters in a bracketed character class can come from a bunch of
sources, all bundled together.  Some things under /d match only when the
target string is UTF-8; some match only when it isn't UTF-8.  Other
sources may introduce ones that match regardless.  It may be that some
things are specified as conditionally matching from one source, and as
unconditionally matching from another.  We can subtract the
unconditionals from the conditionals, leaving a simpler set of things
that must be conditionally matched.  In some cases, the conditional set
may go to zero, allowing other optimizations to happen that otherwise
couldn't.  An example is

    qr/[\W\xAB]/

which before this commit compiled to:

    ANYOFD[^0-9A-Z_a-z\x{80}-\x{AA}\x{AC}-\x{FF}][{non-utf8-latin1-all}
    {utf8}0080-00A9 00AC-00B4 00B6-00B9 00BB-00BF 00D7 00F7
    02C2-02C5...] (12)

and after it, compiles to

    ANYOFD[^0-9A-Z_a-z\x{AA}\x{B5}\x{BA}\x{C0}-\x{D6}\x{D8}-\x{F6}
    \x{F8}-\x{FF}][{non-utf8-latin1-all}{utf8}02C2-02C5...] (12)

Notice that the {utf8} component has been stripped of everything below
256.  That means no swash has to be created at runtime when matching
code points below 256, unlike the case before this commit.

A starker example, though unlikely in real life except in
machine-generated code, is

    qr/[\w\W]/

Before this commit, it would generate:

    ANYOFD[\x{00}-\x{7F}][{non-utf8-latin1-all}{above_bitmap_all}
    {utf8}0080-00FF]

and afterwards, simply:

[perl #126240] use -DPERL_USE_SAFE_PUTENV where possible on OS X

On threaded builds on OS X, libSystem registers atfork handlers that
call setenv(), which internally modifies members of environ[], setting
them to malloc()ed blocks.

In some cases Perl_my_setenv() reallocates environ[] using
safesysmalloc(), which under debugging builds adds a tracking header,
and if perl_destruct() sees that environ[] has been reallocated, frees
it with safesysfree().

When these combine, perl attempts to free the malloc()ed block with
safesysfree(), which attempts to access the tracking header, causing
an invalid access in tools like valgrind, or a "free from wrong pool"
error, since the header contains unrelated data.

Avoid this mess by letting libc manage environ[] if unsetenv() is
available.
