  XXX craig Unixish.h, doshish.h: Reorder terminations; simplify

The IO and memory terminations need to be after other things.  Add a
comment so that future maintainers won't make the mistakes I did.

Also refactor to that amiga os doesn't have a separate list to get out
of sync

I suspect that the amiga termination should be moved to earlier in
the sequence, but absent any evidence; I'm leaving it unchanged.

  locale.c: Win32: Don't check folds validity

This code will check, when warnings are on, that the libc functions
return valid values.  But Windows platforms will always fail because
they have multiple divergences from the Posix standard.  The macros that
implement the case changing/folding in handy.h take extra steps to bring
Windows code more into alignment with Posix.  Those are too complicated
to easily duplicate the logic here.  The result of these checks is
looked at by our test suite, which has long, without anyone noticing,
skipped portions on Windows, even though handy.h should correct for
this.  So simply, don't do the checking under Windows, and find out what
handy.h has failed to fully correct for.

  DEBUG_L now also looks at environment variable

Because locale initialization happens before command line processing,
one can't pass a -DL argument to enable debugging of locale
initialization.  Instead, an environment variable is read then, and is
used to enable debugging or not.  In the past, code specifically had to
test for this being set.  This commit changes that so that debugging can
automatically be enabled without having to write special code.  Future
commits will strip out those special checks.

This commit changes what happens on platforms without locale handling to

called the libc locale-dependent functions and made sure the result was
ASCII.  I think this is a holdover from before we had the precomputed
definitions

  handy.h: Add wrapper layer macros for isalnum() ...

This adds a new set of macros, forming a lower layer to what is currently
there to wrap the character classification libc functions, isdigit()
etc, and case changing ones, tolower(), toupper().

On most platforms these expand simply to the libc function call.  But on
windows, they expand to something more complex, to bring the Windows
calls into POSIX compliance.  Previously that was achieved at the higher
level, with the result that lower level calls were broken.  This
resulted in parts of the test suite being skipped on Windows.

The current level is rewritten to use the new lower layer, with the
result that it is simpler, as the complexity is now done further down.

I thought about calling these macros is_porcelain_isalnum or something
similar to emphaisze that they are close to the bare libc version, but
thought isU8_alnum() is shorter and conveys another truth, that being
the input is assumed to be a byte, without checking.

These case statements in a switch all had the same prelude for checking

the common UTF-8 handling, and then puts the lower lever things in the
switch().  Perhaps the C optimizer will be smart enough to do this too,
but we might as well do it ourselves, now that it is convenient.

  locale.c: Create S_get_category_index()

libc locale categories, like LC_NUMERIC, are opaque integers.  This
makes it inconvenient to have table-driven code.  Instead, we have
tables that are indexed by small positive integers, which are a
compile-time mapping from the libc values.

This commit creates a run-time function to also do that mapping.  It
will first be used in the next commit.

The function does a loop through the available categories, looking for a
match.  It could be replaced by some sort of quick hash lookup, but the
largest arrays in the field have a max of 12 elements, with almost all
searches finding their quarry in the first 6.  It doesn't seem
worthwhile to me to replace a linear search of 6 elements by something
more complicated.  The design intent is this search will be used only at
the edges of the locale-handling code; once found the index is used in
future bits of the current operation.

  locale.c: Use get_category_index()

This creates the first uses of the function added in the previous commit.

It changes the name of a function that now takes an index to have the
suffix _i to indicate its calling parameter is a category index rather
than a category.  This will become a common paradigm in this file in
later commits.

Two macros are also created to call that function; they have suffixes _c
(to indicate the parameter is a category known at compile time, and _r
(to indicate it needs to be computed at runtime).  This is in keeping
with the already existing paradigm in this file.

  locale.c: Change S_emulate_setlocale name and sig

It turns out this function is called only from places where we have the
category index already computed; so change the signature to use the
index and remove the re-calculation.

It renames it to emulate_setlocale_i() to indicate that the category
parameter is an index.

This also means, that it's very unlikely that it will be called with an
out-of-bounds value.  Remove the debugging statement for that case (but
retain the error return value).

There are two sets of names, which immediately indicate if the result
can be relied on to be thread level or must be assumed to be global to

since on a threadless perl, it's a don't care; and on a threaded perl,
they are all already thread-level, in the Configurations we support.

Future commits will cause the macros to diverge, and comments will be
added then.

For POSIX 2008, this commit causes queries to go directly to the query
function, avoiding S_emulate_setlocale_i() completely.

  Perl_setlocale(): Same code for all param2 == NULL

Calling Perl_setlocale() with a NULL 2nd parameter returns the current
locale, rather than changing it.  Previously LC_NUMERIC and LC_ALL were
treated specially; other categories were lumped in with the code that
changes the locale.

Changing some categories involves a non-trivial amount of work.  This
commit avoids that by moving all queries to the same 'if' branch.
LC_NUMERIC and LC_ALL still have to be treated specially, but now it's
all within the same outer 'if', and the unnecessarily executing code
for when the locale changes is avoided.

  locale.c: Create new convenience macro

glibc doesn't have the querylocale() function, available on some other
platforms, such as Darwin and *BSD.  However, it instead has the
equivalent functionality available through an undocumented feature.

This commit allows someone in the know to compile perl to use that
feature, and wraps its API with a macro so that the calling code doesn't
have to be aware of the different APIs of the two methods.

That macro's definition is now done in perl.h, as future commits will
use it in other files.

Since this is an undocumented feature, I am not currently documenting
this wrapper availability.  However, it has been used in the field
without complaint for a couple of releases, as follows:  A more
cumbersome substitute method continues to be used to get what it does.
But in the past both methods were tried and the program died if they
yielded different results.  Since no one has complained, I'm fairly
confident it works.  But sill I'm deferring its more general use.

  locale.c: querylocale() doesn't work on LC_ALL

I had misread the man pages.  This bug has been in the field for several
releases now, but most likely hasn't shown up because it's almost always
the case that the locale categories will be set to the same locale.  And
so most implementations of querylocale() would return the correct
result.

This commit works by splitting the calculation of the value of LC_ALL
from S_emulate_setlocale_i() into a separate function, and extending it
to work on querylocale() systems.  This has the added benefit of
removing tangential code from the main line, making
S_emulate_setlocale_i easier to read.

calculate_LC_ALL() is the new function, and is now called from two
places.  As part of this commit, constness is added to PL_curlocales[]

Part of this change is to keep our records of LC_ALL on non-querylocale
systems always up-to-date, which is better practice

And part of this change is temporary, marked as such, to be removed a
few commits later.

  -----------
  locale.c: locale "" can be disparate

Setting a locale "" means to get the value from environment variables.
These can set locale categories to different locales, and this needs to
be handled.  The logic before this commit only handled the disparate
case when the locale wasn't ""; but this was compensated for elsewhere.
A future commit will remove that compensation.

  locale.c: Add fcn to hide edge case undefined behavior

The POSIX 2008 API has an edge case in that the result of most of the
functions when called with a global (as opposed to a per-thread) locale
is undefined.

The duplocale() function is the exception which will create a per-thread
locale containing the values copied from the global one.

This commit just calls duplocale, if needed, and the caller need not
concern itself with this possibility

But it dawned on me that if the arbitrary date we use to do our
calculations were such that it was for a year in which January 1 falls
on a Sunday, then the util.c version automatically works.

and copied the way cygwin does it.

This also no longer returns just an empty string in certain cases.
nl_langinfo() itself doesn't, so conform to that.

  locale.c: Improve non-nl_langinfo() CODESET calc

Prior to this commit, on non-Windows platforms that don't have a
nl_langinfo() libc function, the code completely punted computation of
the CODESET item.  I have not been able to figure out how to do this,
even going to the locale definition files on disk (which may vary
anyway), but we can do a lot better than punting.

This commit adds three checks:

1) If the locale name is C or POSIX, we know the codeset

2) We can detect if a locale is UTF-8.  If it is, that is the codeset.
Many modern locales are of this ilk.

3) Failing that, some locales have the codeset appear in the name,
following a dot.

It isn't perfect, but it's a lot better than completely punting.

This commit changes the calling sequence for my_langinfo to add the
desired locale (or a sentinel to indicate to use the current locale),
and the locale category of the desired item.

This allows the function to be able to return the desired value for any
locale, avoiding some locale changes that would happen until this
commit, and hiding the need for locale changes from outside functions,
though a couple continue to do so to avoid potential multiple changes.

Previous commits have added the infrastructure to be able to determine

places, with more to come in future commits.

This uses as a final fallback, mbtowc(), which some sources view was a
late adder to C89, and others as not really being available until C99.
Future commits will add heuristics when that function isn't available.

  XXX perldelta Move POSIX::localeconv() logic to locale.c

The code currently in POSIX.xs is moved to locale.c, and reworked some
to fit in that scheme, and the logic for the workaround for the Windows
broken localeconv() is made more robust.

This is in preparation for the next commit which will use this logic
instead of (imperfectly) duplicating it.

This also creates Perl_localeconv() for direct XS calls of this
functionality.

  locale.c: Collapse duplicate logic into one instance

The previous commit move the logic for localeconv() into locale.c.  This
commit takes advantage of that to use it instead of repeating the logic.

On Windows, there is alternative way of finding the radix character for
systems that have a localeconv() that could cause a race.  Prior to this
commit, if that failed to find something that looked like the radix, it
returned a '?'.  Now it will drop down to using this new code, as the
likelihood of the race is small.

Notably, this commit removes the inconsistent duplicate logic that had
been used to deal with the Windows broken localeconv() bug.

  locale.c: Fix windows bug with broken localeconv()

localeconv() was broken on Windows until VS 2015.  As a workaround, this
was using my_snprintf() to find what the decimal point character is,
trying to avoid our workaround for localeconv(), which has a (slight)
chance of a race condition.

The problem is that my_snprintf() might not end up calling snprintf at
all; I didn't trace all possibilities in Windows.  So it doesn't make
for a reliable sentinel.

This commit now specifically uses libc snprintf(), and if it fails, drops
down to try localeconv().

  Avoid mojibake in "$!"

In stress testing, I discovered that the LC_CTYPE and LC_MESSAGES
locales need to be the same locale, or strerror() can return
question marks or mojibake instead of the proper message.

This commit refactors the handling of stringifying "$!" to make the
locales of both categories the same during the stringification.

Actually, I suspect it isn't the locale, but the codeset of the locale
that needs to be the same.  I suspect that if the categories were both
in different UTF-8 locales, or both in single-byte locales, that things
would work fine.  But it's cheaper to find the locale rather than the
locale's codeset, so that is what is done.

there is now a single entry cache, so I don't think the complexity
warrants keeping it.

It could be added back if necessary, split off from the remainder of

  Swap the ordering of two locale category indices

Perl internally uses a mapping of locale category values into a
consecutive sequence of indices starting at 0.  These are used as
indexes into arrays.  The reason is that the category numbers are
opaque, vary by platform, aren't necessarily sequential, and hence are
hard to make table driven code for.

This commit makes the LC_CTYPE index 0, and LC_NUMERIC equal to 1;
swapping them.  The reason is to cause LC_CTYPE to get done first in the
many loops through the categories.  The UTF8ness of categories is an
often needed value, and most of the time the categories will have the
same locale.  LC_CTYPE is needed to calculate the UTF8ness, and by doing
it first and caching the result, the other categories likely
automatically will use the same value, without having to recalculate.

This reorders the function so that on POSIX 2008 platforms, the numeric

platforms, as we already have the correct value in place for querying
what the radix and thousands separator characters are.

Explanatory comments are also added.

  locale.c: Don't assume LC_CTYPE, LC_COLLATE are same

This code is using isCNTRL_LC which depends on LC_CTYPE to verify that
something in the LC_COLLATE locale is a control.  That only works
properly if the two locales are the same.  This commit adds code to
ensure they are.

  locale.c: strxfrm() requires LC_CTYPE eq LC_COLLATE

The libc functions strxfrm() on some platforms requires the LC_CTYPE
locale to be the same as the LC_COLLATE locale (or rather, probably that
they have the same code set, but checking for locale is cheaper).
Otherwise mojibake would result, or more likely the function will fail,
setting errno.

This commit brings the locales into alignment if necessary

prior to this commit it would do if the LC_COLLATION locale were

  Use general locale mutex for numeric operations

This commit removes the separate mutex for locking locale-related
numeric operations on threaded perls; instead using the general locale
one.  The previous commit made that a general semaphore, so now suitable
for use for this purpose as well.

This means that the locale can be locked for the duration of some
sprintf operations, longer than before this commit.  But on most modern
platforms, thread-safe locales cause this lock to expand just to a
no-op; so there is no effect on these.  And on the impacted platforms,
one is not supposed to be using locales and threads in combination, as
races can occur.  This lock is used on those perls to keep Perl's
manipulation of LC_NUMERIC thread-safe.  And for those there is also no
effect, as they already lock around those sprintf's.

  Add locale macro to wrap static-space-using fncs

Some functions return a result in a global-to-the-program buffer, or
they have an internal global buffer.  Other threads must be kept from
simultaneously using that function.  This macro is to be used for all
such ones dealing with locales.  Ideally, there would be a separate mutex
for each such buffer space.  But these functions also have to lock the
locale from changing during their execution, and there aren't that many
such functions, and they actually are rarely executed.  So a single lock
will do.

This will allow future commits to have more targeted locking for
functions that don't affect the global locale.

  XXX perlembed Add PORCELAIN_SETLOCALE_LOCK/UNLOCK

This macro is used to surround raw setlocale() calls so that the return
value in a global static buffer can be saved without interference with
other threads.

There are a few very rarely occurring instances in locale.c that are
converted to use this.  These previously could have been races.

The raw setlocales in the initialization function are not guarded, as
these happen early in the Perl process initialization, before threading
is enabled.

This is buggy if there are multiple embedded perls.  It can't be helped.
perlembed is being updated to indicate this.

  locale.c: Mitigate unsafe threaded locales

This a new set of macros and functions to do locale changing and
querying for platforms where perl is compiled with threads, but the
platform doesn't have thread-safe locale handling.

All it does is:

1) The return of setlocale() is always safely saved in a per-thread
buffer, and
2) setlocale() is protected by a mutex from other threads which are
using perl's locale functions.

This isn't much, but it might be enough to get some programs to work on
such platforms which rarely change or query the locale.

  Make fc(), /i thread-safe on participating platforms

A long standing bug in Perl that has gone undetected is that the array
is global that is created when changing locales and tells fc() and qr//i
matching what the folds are in the new locale.

What this means is that any program only has one set of fold definitions
that apply to all threads within it, even if we claim that the locales
are thread-safe on the given platform.  One possibility for this going
undetected so long is that no one is using locales on multi-threaded
systems much.  Another possibility is that modern UTF-8 locales have the
same set of folds as any other one.

It is a simple matter to make the fold array per-thread instead of
per-process, and that solves the problem transparently to other code.

I discovered this stress-testing locale handling under threads.  That
test will be added in a future commit.

  perl.h: Finish implementing combo ENV/LOCALE mutexes

There are cases where an executing function is vulnerable to either the
locale or environment being changed by another thread.  This commit
implements macros that use mutexes to protect these critical sections.
There are two cases that exist:  one where the functions only read; and
one where they can also need exclusive control so that a competing
thread can't overwrite the returned static buffer before it is safely
copied.

5.32 had a placeholder for these, but didn't actually implement it.
Instead it locked just the ENV portion.  On modern platforms with
thread-safe locales, the locale portion is a no-op anyway, so things
worked on them.

This new commit extends that safety to other platforms.  This has long
been a vulnerability in Perl.

adding an additional fallback, specified in C89, which isn't a great
substituted, but far better than nothing.

  locale.c: Rmv unused code

The code to handle changing LC_NUMERIC and LC_COLLATION handled the
possibility of being passed a NULL locale name.  But we're not changing
things unless we have a new locale, and know its name, so a name is
always passed

  locale.c: Add 'Lazy' location changing

When comparing two strings for order under 'use locale', one can call
strcoll() which creates hidden modified versions of the strings based on
the locale's collation ordering, does the comparison, and then throws
away the modified versions.

Or one can call strxfrm() to create a non-hidden modified version of
each string, and then do a straight comparison.  The advantage here is
that you are in control of when to discard the modified version, and the
(expensive) transformation is done just once, no matter how many times a
comparison is done.

Perl assumes that a string will be compared multiple times, so the first
time it happens under 'use locale', strxfrm() is called, and the
modified string is attached via magic to the SV.  The modified string is
discarded if the string changes, or is recomputed if the locale has
changed since the computation was done.

The transformation generally occupies some multiple of size of the
original string.  Memory must be allocated to hold it.  For any given
locale, the amount is predictable for all strings, roughly via a linear
equation "mx+b", where x is the size of the original string.  By
computing 'm' and 'b' once, Perl can allocate enough memory to hold the
transformation, but not too much.  (m and b are adjusted up as necessary
as more strings get transformed.)  This minimizes mallocs.

But the calculation of m and b is somewhat expensive, and only necessary
if the program actually does a string compare under 'use locale'.

This commit defers the calculation until needed.  It does the bare
minimum of changes accomplish this.  The next commit will rearrange
things.

  locale.c: Move code, white-space, comment only

This moves the function created in the previous commit to a more logical
place in the file; just before its only call.  It also removes nested
blocks that are no longer necessary.
