  perl.h: remove UNION_ANY_DEFINITION support

This macro, if defined, is supposed to provide an alternative definition
of the `union any` type. It was added in commit 0f4eea8fa1779e0 (June
1998) to let win32.h override `union any` with its own definition. That
override was removed from win32.h in commit c06b86730d867c (July 1999).

For the past 25 years, this feature has been sitting there undocumented
and unused.

If any of these format strings are empty, things can go very wrong at
runtime, from garbage output to segfaults (e.g. see #22375).

This is a static check, so it could be placed in any source file. I
chose util.c because according to the comment at the top, it is the home
of "any stuff that people couldn't think of a better place for".

- three `goto`s and a label
- one duplicate instance of `PUSHs(boolSV(fchdir(...) >= 0))`
- one `#ifdef ... #endif` section

  add ::chdir (properly)

Previously, CORE::chdir was not "ampable", i.e. it could not be called
through a coderef or with a sigil: ::chdir($dir);

The only thing allowed was to make a compile-time alias, whose calls
would then be inlined to chdir again:

BEGIN { *foo = \::chdir; }
foo ".";  # actually does chdir "."

However, this was broken if the function call used parentheses, in which
case chdir would always try to use its argument as a filehandle, not the
name of a directory:

BEGIN { *foo = \::chdir; }
foo(".");
# Triggers a warning:
# chdir() on unopened filehandle . at file line 2.

This commit fixes the problem and makes chdir fully "ampable", so
::chdir() no longer triggers the "::chdir cannot be called
directly" error.

  sort: fix display of verbatim blocks by using spaces, not tabs

The `use sort 'defaults';` line used only one tab before the comment;
the other lines had two. This renders inconsistently depending on how
much initial space is used in the output (and where the tab stops are).

For example,  looked like

use sort 'stable';  # guarantee stability
use sort 'defaults';# revert to default behavior
no  sort 'stable';  # stability not important

Using spaces ensures the "#" signs are aligned everywhere.

  Fcntl: remove pointless S_ISENFMT function

S_ISENFMT($mode) has no equivalent C macro. It was implemented (in XS)
as the equivalent of `($mode & S_IFMT) == S_ENFMT`, which is always
false because S_ENFMT is not a file type and thus not covered by the
S_IFMT mask.

(See commits ca6e1c2, 0e6f150, 0f68039, fb59364, 87eca6e for the history
of this function, which has always been broken in various ways ever
since it was added in 2000.)

Fixes #22190.

  perlfunc/stat: fix description of S_ENFMT and S_IFMT

S_ENFMT properly belongs to the group of permission bits (like
setuid/setgid), not file types. On systems that have it (like AIX), it
can be set/cleared with chmod(). (In fact, it usually shares its value
with S_ISGID because enforced locking is signaled by the combination of
a non-executable file with the setgid bit set.)

S_IFMT($mode) directly gives you one of the file types (S_IFREG,
S_IFDIR, etc). You don't need to bit-and it further (especially not with
the S_IS* functions), contrary to what the comment claims. (The
confusion likely stems from the C side of things, where you'd do `mode &
S_IFMT` to extract the file type from the mode bits, leading to code
like `(mode & S_IFMT) == S_IFDIR`. But even then you could write
`S_ISDIR(mode)` without any bit mask trickery.)

Most of the symbols in the "S_IF* constants" section don't start with
"S_IF", so change to "S_I* constants" everywhere.

Most of the symbols in the "S_IF* functions" section don't start with
"S_IF" (with the sole exception of S_IFMT, which is only a function in
Perl; the C macro is a constant).
(Historical note: This section label used to make more sense because it
documented S_IFMODE and S_IFMT functions, but the former was just a typo
for S_IMODE.)

  h2ph: define all symbols at runtime

Preprocessor directives must be processed strictly in order. `#if` and
`#ifdef` directives can inspect the current state of defined symbols.
That's why it is wrong to translate `#define FOO() ...` to `sub foo() {
... }` since subroutine definitions are processed unconditionally at
compile time, before the rest of the code starts running.

In particular,

unless(defined()) {
sub FOO () { eval q(1); }
}

is equivalent to

# at compile time:
sub FOO () { eval q(1); }

# ... later, at runtime:
unless(defined()) {
# does nothing
}

Fix this case by always wrapping subroutines in eval '...', which moves
the symbol definition to runtime, regardless of what $t (our indentation
state) is.

Similarly, generate `_h2ph_pre.ph` without the functionally useless
`unless (defined &...) { }` blocks. We don't need runtime definitions
(via eval) here because nothing in this file depends on the dynamic
state of macro definitions. It's all `#define`s, no `#if`s.

Fixes #22109.

  regcomp: OPFAIL is neither SIMPLE nor HASWIDTH

This is an extension of fc7dfe8e82a76ba43c, which marked zero-width
constructs as non-SIMPLE.

This change affects synthetic OPFAIL nodes generated by the regclass
optimizer (empty character classes like [^\W\S] should always fail to
match), but which were still marked SIMPLE (indicating they match
exactly one character). If such a character class is under a quantifier,
it would cause regrepeat() to panic at runtime.

Fixes #22094.

config.h:4052:18: note: format string is defined here
 #define U32uf  "lu"  /**/

This is because the code tries to format __LINE__ with a varargs
function using %"LINE_Tf".

Things are slightly tricky here because in a varargs function, no type
context is available, so the format string absolutely has to match the
intrinsic type of each argument. The __LINE__ macro expands to a simple
(decimal) integer constant. According to C, such a constant has type int
if its value fits, otherwise unsigned int if it fits, otherwise long
int, etc. None of the *.c files in the perl distribution exceed 32767
lines (the minimum INT_MAX required by C), so even on ancient 16-bit
systems, our __LINE__ will always be of type int.

The %"LINE_Tf" format is designed to match a line_t argument, not int.
(On some platforms, line_t is defined as unsigned long and incompatible
with int for formatting purposes.) Therefore it is an error to use
%"LINE_Tf" with __LINE__.

One way to fix this is to convert the argument to match the format
string: ... %"LINE_Tf" ...", (line_t)__LINE__.

The other way is to change the format string to match the (int)
argument: "... %d ...", __LINE__.

Option 1 is what is used elsewhere in locale.c, so use line_t
consistently for all line numbers.

  fix "uninitialized value" warnings for shift()/pop()

This fixes an oversight introduced in 1b0ae12.

The Perl code "shift" (or "shift()") produces different optrees
depending on where it occurs: At file scope, it shifts @ARGV and the
corresponding OP has an explicit @ARGV child. But at subroutine scope,
it shifts @_, and @_ is not represented explicitly in the optree.
Instead the parser just generates an OP_SHIFT without any children.

This latter case was not handled in S_find_uninit_var (and blindly
accessing a non-existent child OP would crash perl). pop() was similarly
affected.

Fix: Explicitly check whether OPf_KIDS is set on the OP before accessing
the op_first field (plus some tests for this case).

Fixes #21960.

  mention length() in "uninitialized value" warnings

When perl looks for the source of "uninitialized value" warnings, it
treats length() as transparent: length(X) is undef iff X is undef, so it
makes sense to ignore length() when looking for the origin of the undef
value. However, this makes for misleading diagnostics: If $x is undef,
then 'length($x) == 0' triggers a "Use of uninitialized value $x in
numeric eq (==)" warning. This is correct insofar as (==) encountered an
undef value and $x is its origin, but incorrect in that $x is not one of
the operands of (==) in the source code.

This patch skips over length() when looking for the origin of undef (as
before), but adds "length(...)" around the name of the variable found,
if any.

Before:

$ perl -we 'my $x; $_ = length $x == 0'
Use of uninitialized value $x in numeric eq (==) at -e line 1.

(Misleading: $x is not an operand of (==).)

After:

$ perl -we 'my $x; $_ = length $x == 0'
Use of uninitialized value length($x) in numeric eq (==) at -e line 1.

Fixes #21930.

  special-case shift/pop/splice in "uninitialized value" warnings

Before the preceding commit, this warning was halfway correct:

$ perl -we 'my @x; $_ = length(shift @x) == 0;'
Use of uninitialized value within @x in numeric eq (==) at -e line 1.

The "uninitialized value" did come from @x (sort of), but it was never
an element of @x, and no element of @x was used as an operand of (==).

After the preceding commit, we get:

Use of uninitialized value length(within @x) in numeric eq (==) at -e line 
1.

... which is invalid code. With this commit, we get:

Use of uninitialized value length(shift(@x)) in numeric eq (==) at -e line 
1.

(The same logic applies to pop().)

Also, splice() was overly optimistic in assigning blame:

$ perl -we 'my @x = 42; $_ = splice(@x, 0, 0) == 0'
Use of uninitialized value within @x in numeric eq (==) at -e line 1.

@x doesn't contain any undefs. The undef encountered by (==) was
returned from splice itself; it didn't come from any of splice's
arguments, so mentioning @x was just wrong.

With this commit we get:

Use of uninitialized value in numeric eq (==) at -e line 1.

  make generic "Out of memory!" error more specific

The problem: When perl runs out of memory, it outputs a generic "Out of
memory!" error and exits. This makes it hard to track down what's
happening in a complex system, especially since the message does not
even mention perl.

This patch contains two main changes:

1. vec() in lvalue context can throw fake "Out of memory!" errors when
   it discovers that the index being assigned to is too big. Unlike real
   allocation errors, these are trappable with try {}/eval {}.

   This message has been changed to "Out of memory during vec in lvalue
   context" (and since it comes from a Perl_croak() call, it will
   generally have a script name and line number attached).

2. All other places in the source code that can emit "Out of memory!"
   errors have been changed to attach a location identifier to the
   message. For example: "Out of memory in perl:util:safesysmalloc"

   This way the error message at least mentions "perl".

Fixes #21672.

  bisect: explicitly set diff path prefixes

The patch code in Porting/bisect-runner.pl assumes `git show` will
always display filenames with "a/..." and "b/..." prefixes. This is not
necessarily the case. For example, the config settings
diff.mnemonicPrefix and diff.noprefix can cause different prefixes or no
prefixes at all to be used. In that case (e.g. after `git config
--global diff.noprefix true`), bisect will halt like this:

|Configure should avoid looping infinitely repeating the same question
|
|Configure's helper function ./myread is intended to loop until it gets 
an
|acceptable answer. For a couple of cases, an empty string is not 
acceptable
|(eg 'Where is your C library?', if all automated attempts at answering 
this
|have failed). In these cases, if Configure's standard input is 
/dev/null (or
|closed), the shell read returns an empty string, and ./myread repeats 
the
|question.
|
|Before this commit, it would loop infinitely (generating continuous 
terminal
|output). With this commit, we add a retry counter - if it asks the same
|question to many times, it aborts Configure. This means that unattended
|./Configure runs should now always terminate, as termination with an 
error
|is better than spinning forever.
|
|diff --git Configure Configure
|index 9d7fc39419..9d3b5f73b1 100755
|--- Configure
|+++ Configure
--
File to patch:

... which seems silly, seeing as how the filename is right there ("diff
--git Configure Configure", "--- Configure", "+++ Configue") and yet
bisect has to ask which file to patch ("it's Configure, duh!").

This commit tells git explicitly to use "a/" and "b/" as prefixes, which
works no matter what the local config settings are.

  don't optimize (or warn about) control flow ops in OP_SASSIGN

In short, '$a = return $b' is stored "backwards": OP_SASSIGN has the RHS
of the assignment as its first operand. Warning about precedence makes
no sense here.

Logical assignment ops like //=, ||=, &&= are represented as
OP_{DOR,OR,AND}ASSIGN wrapped around a weird single-child OP_SASSIGN.
Trying to naively elide the inner OP_SASSIGN leaves a dangling outer
OP_{DOR,OR,AND}ASSIGN (which B::Deparse doesn't know what to do with) or
just makes the compiler loop indefinitely. So just don't.

Fixes #21665.

  elide right operand if left operand transfers control

This commit contains the following changes:

- The "possible precedence issue" warning now mentions (in parentheses)
  the name of the control flow operator that triggered the warning:

  $ ./perl -cwe 'return $a or $b'
  Possible precedence issue with control flow operator (return) at -e line 
1.

- CORE::dump now counts as a control flow operator:

  $ ./perl -cwe 'CORE::dump or f()'
  Possible precedence issue with control flow operator (dump) at -e line 1.

- Any binary operator whose left operand is a control flow operator is
  optimized out along with any right operand it may have, even if no
  warning is triggered:

  $ ./perl -Ilib -MO=Deparse -we '(die $a) + $b'
  BEGIN { $^W = 1; }
  die $a;
  -e syntax OK

  (No warnings because explicit parentheses are used in the preceding
  example.)

  $ ./perl -Ilib -MO=Deparse -we 'exit $a ? 0 : 1'
  Possible precedence issue with control flow operator (exit) at -e line 1.
  BEGIN { $^W = 1; }
  exit $a;

  extend "Possible precedence issue" warning, cover more cases

Previously, code like

return $a or $b;

would emit a warning of the form "Possible precedence issue with control
flow operator" because it parses as (return $a) or $b.

However, the equally misleading

exit $a != 0;  # exit($a) != 0
exit $a ? 0 : $b;  # exit($a) ? 0 : $b

were not diagnosed.

This patch moves the check higher up in the compiler: Now any binary or
ternary operator (not just logical operators) warns if its first operand
is an unparenthesized control flow operator that does not terminate
normally (i.e. next, last, redo, goto, exit, return, die).

  perl5300delta: mention removal of arybase module

arybase was the internal module implementing the $[ feature. While the
removal of $[ is documented, the removal of arybase was not. This commit
tries to fix the oversight.

(Programmers were not supposed to use arybase directly, but it had its
own POD documentation and was officially listed as a core module in
perlmodlib, and previous perldeltas documented version changes in
arybase, so I feel its removal should be mentioned as well.)

  POSIX: fix mktime on 32-bit platforms with large time_t

If IV is a 32-bit type, but time_t is bigger, then it is possible for
mktime() to return values outside the 32-bit range (> 0x7fff_ after
2038-01-19). In that case, fall back to NV (i.e. floating point). A
double-precision floating point number provides more than 52 bits of
precision, which should be plenty.

  perlre: remove statement suggesting /p is a no-op

Perl's documentation used to say that /p became a no-op starting in
v5.20.0 and all regexes would now set ${^PREMATCH}, ${^MATCH}, and
${^POSTMATCH}. This is not the case.

This wording was removed from perlvar in commit 60c52570a7183b5ef7, but
a similar sentence in perlre was missed.

This commit removes the erroneous statement from perlre and changes "and
performance penalty" to "the performance penalty" in perlvar, which
looks like a typo that got copy/pasted around.

(less-or-equal) never matches (unless p == '*'). That is, if you are on
v5.38.0 and want to check PERL_VERSION_LE(5, 38, 0), it'll return false.

Fix: Switch to '<=' and change the logic for '*' to bump the patch
version up to 999, which is the maximum supported by the encoding that
PERL_JNP_TO_DECIMAL_ uses.

Also add some ad-hoc sanity checks for the version comparison macros.

Fixes #21506.

  fix PERL_JNP_TO_DECIMAL_

Commit 4a1bbd3d3953c4 added the multiplication by 10. As the comment
explains, this is to leave room for alpha/beta releases.

However, the expression is parenthesized such that the '10 *' part only
applies to the major version; i.e. major is now effectively multiplied
by 10_000_000 instead of 1_000_000.

Change this to multiply the whole thing by 10. That way we get an extra
digit at the bottom, which seems to have been the original intent.

An early exit in pp_anonhash (added in 7a607afee585e60ce329b)
inadvertently made { $foo } behave like {}; i.e. a hashref constructor
containing a single value ended up returning a reference to an empty
hash (and did not emit an "Odd number of elements in anonymous hash"
warning).

Fixes #21478.

  perl.pod: use spaces instead of tabs for alignment

On some platforms/formatters, the documentation overview in 'perldoc
perl' renders badly (misaligned) because tabs are interpreted
differently. This is presumably because some renderers output all of the
leading spaces in a verbatim paragraph as-is, while others don't.

For example, https://perldoc.perl.org/perl currently shows for me:

|
v
...
perlsyn Perl syntax
perldataPerl data structures
perlop  Perl operators and precedence
perlsub Perl subroutines
perlfuncPerl built-in functions
  perlopentut   Perl open() tutorial
  perlpacktut   Perl pack() and unpack() tutorial
perlpod Perl plain old documentation
perlpodspec Perl plain old documentation format specification
perldocstylePerl style guide for core docs
perlpodstylePerl POD style guide
perldiagPerl diagnostic messages
perldeprecation Perl deprecations
perllexwarn Perl warnings and their control
perldebug   Perl debugging
perlvar Perl predefined variables
...
^
|

All of the "Perl"s in the second column should be aligned like the
"perldeprecation" line, which is the only one that uses spaces in the
original POD document (the others use either one tab, two tabs, or a mix
of spaces and tabs).

By using spaces everywhere we bypass the whole issue and get
consistently aligned results, no matter how tabs are rendered.

  perlop, perlsyn: make abstract more verbose/precise

If you're looking for the syntax of Perl expressions or strings, you
might think that "perlsyn - Perl syntax" is the document you need. But
perlsyn is mostly about syntax at the statement level. Expressions
(including how string literals are parsed, available escape sequences,
etc) are documented in perlop instead.

Hopefully, making the abstract slightly more verbose will make it easier
for people to find the documentation they're looking for.

-!- Pull-Request [~pull-requ@40.84.179.161] has left #p5p []

Six of those are redundant because botifico already handles everything.

This commit gets rid of the empty message by stripping trailing newlines
from the YAML string. It also tries to fix the "merged PR" and "closed

It also disables #p5p IRC notifications by default. They can be enabled
by setting the github project variable NOTIFY_IRC_P5P to 'true'.

variable and jumping before the `if` block that checks the variable, we
can just jump into the block and get rid of the variable.

  report uninit variable name even in optimized cases

Several cases that used to be simple assignment ops with lexical
variables have been optimized in some way:

 - $foo = undef is now a single OP_UNDEF with special flags
 - $foo = ... is now a single OP_PADSV_STORE
 - $foo[0] = ... is now a single OP_AELEMFASTLEX_STORE

This is mostly transparent to users, except for "Use of uninitialized
value" warnings, which previously mentioned the name of the undefined
variable, but don't do so anymore in blead.

This commit teaches find_uninit_var() about the new ops, so error
messages for these ops can mention variable names again.

Fixes #20945.

  fix incorrect vi filetype declarations in generated files

Vim's filetype declarations are case sensitive. The correct types for
Perl, C, and Pod are perl, c, and pod, respectively.

  don't set a special filetype for generated .gitignore

Previously it would default to Perl, which happens to produce the right
comment character ("#"), but results in nonsensical syntax highlighting.
Now we set $lang to the special value 'None', which still produces
read-only declarations, but doesn't force a mode/filetype on editors.
