NAME
perlintern - autogenerated documentation of purely internal
Perl functions
DESCRIPTION
This file is the autogenerated documentation of functions in
the Perl interpreter that are documented using Perl's
internal documentation format but are not marked as part of
the Perl API. In other words, they are not for use in
extensions!
CV reference counts and CvOUTSIDE
CvWEAKOUTSIDE
Each CV has a pointer, "CvOUTSIDE()", to its
lexically enclosing CV (if any). Because pointers to
anonymous sub prototypes are stored in "&" pad
slots, it is a possible to get a circular reference,
with the parent pointing to the child and vice-
versa. To avoid the ensuing memory leak, we do not
increment the reference count of the CV pointed to
by "CvOUTSIDE" in the one specific instance that the
parent has a "&" pad slot pointing back to us. In
this case, we set the "CvWEAKOUTSIDE" flag in the
child. This allows us to determine under what
circumstances we should decrement the refcount of
the parent when freeing the child.
There is a further complication with non-closure
anonymous subs (i.e. those that do not refer to any
lexicals outside that sub). In this case, the
anonymous prototype is shared rather than being
cloned. This has the consequence that the parent may
be freed while there are still active children, eg
BEGIN { $a = sub { eval '$x' } }
In this case, the BEGIN is freed immediately after
execution since there are no active references to
it: the anon sub prototype has "CvWEAKOUTSIDE" set
since it's not a closure, and $a points to the same
CV, so it doesn't contribute to BEGIN's refcount
either. When $a is executed, the "eval '$x'" causes
the chain of "CvOUTSIDE"s to be followed, and the
freed BEGIN is accessed.
To avoid this, whenever a CV and its associated pad
is freed, any "&" entries in the pad are explicitly
removed from the pad, and if the refcount of the
pointed-to anon sub is still positive, then that
child's "CvOUTSIDE" is set to point to its
grandparent. This will only occur in the single
specific case of a non-closure anon prototype having
perl v5.12.5 Last change: 2014-06-17 1
Perl Programmers Reference Guide PERLINTERN(1)
one or more active references (such as $a above).
One other thing to consider is that a CV may be
merely undefined rather than freed, eg "undef &foo".
In this case, its refcount may not have reached
zero, but we still delete its pad and its "CvROOT"
etc. Since various children may still have their
"CvOUTSIDE" pointing at this undefined CV, we keep
its own "CvOUTSIDE" for the time being, so that the
chain of lexical scopes is unbroken. For example,
the following should print 123:
my $x = 123;
sub tmp { sub { eval '$x' } }
my $a = tmp();
undef &tmp;
print $a->();
bool CvWEAKOUTSIDE(CV *cv)

Functions in file pp_ctl.c
docatch Check for the cases 0 or 3 of cur_env.je_ret, only
used inside an eval context.
0 is used as continue inside eval,
3 is used for a die caught by an inner eval -
continue inner loop
See cop.h: je_mustcatch, when set at any runlevel to
TRUE, means eval ops must establish a local jmpenv
to handle exception traps.
OP* docatch(OP *o)
GV Functions
gv_try_downgrade
If the typeglob "gv" can be expressed more
succinctly, by having something other than a real GV
in its place in the stash, replace it with the
optimised form. Basic requirements for this are
that "gv" is a real typeglob, is sufficiently
ordinary, and is only referenced from its package.
This function is meant to be used when a GV has been
looked up in part to see what was there, causing
upgrading, but based on what was found it turns out
that the real GV isn't required after all.
If "gv" is a completely empty typeglob, it is
deleted from the stash.
If "gv" is a typeglob containing only a
sufficiently-ordinary constant sub, the typeglob is
replaced with a scalar-reference placeholder that
more compactly represents the same thing.
NOTE: this function is experimental and may change
or be removed without notice.
void gv_try_downgrade(GV* gv)
is_gv_magical_sv
Returns "TRUE" if given the name of a magical GV.
Currently only useful internally when determining if
a GV should be created even in rvalue contexts.
"flags" is not used at present but available for
future extension to allow selecting particular
classes of magical variable.
Currently assumes that "name" is NUL terminated (as
perl v5.12.5 Last change: 2014-06-17 5
Perl Programmers Reference Guide PERLINTERN(1)
well as len being valid). This assumption is met by
all callers within the perl core, which all pass
pointers returned by SvPV.
bool is_gv_magical_sv(SV *const name_sv, U32 flags)
Hash Manipulation Functions
refcounted_he_chain_2hv
Generates and returns a "HV *" by walking up the
tree starting at the passed in "struct refcounted_he
*".
NOTE: this function is experimental and may change
or be removed without notice.
HV * refcounted_he_chain_2hv(const struct refcounted_he *c)
refcounted_he_free
Decrements the reference count of the passed in
"struct refcounted_he *" by one. If the reference
count reaches zero the structure's memory is freed,
and "refcounted_he_free" iterates onto the parent
node.
NOTE: this function is experimental and may change
or be removed without notice.
void refcounted_he_free(struct refcounted_he *he)
refcounted_he_new
Creates a new "struct refcounted_he". As key is
copied, and value is stored in a compact form, all
references remain the property of the caller. The
"struct refcounted_he" is returned with a reference
count of 1.
NOTE: this function is experimental and may change
or be removed without notice.
struct refcounted_he * refcounted_he_new(struct refcounted_he *const parent, SV *const key, SV *const value)
IO Functions
start_glob
Function called by "do_readline" to spawn a glob (or
do the glob inside perl on VMS). This code used to
be inline, but now perl uses "File::Glob" this glob
starter is only used by miniperl during the build
process. Moving it away shrinks pp_hot.c; shrinking
pp_hot.c helps speed perl up.
NOTE: this function is experimental and may change
or be removed without notice.
perl v5.12.5 Last change: 2014-06-17 6
Perl Programmers Reference Guide PERLINTERN(1)
PerlIO* start_glob(SV *tmpglob, IO *io)
Magical Functions
magic_clearhint
Triggered by a delete from %^H, records the key to
"PL_compiling.cop_hints_hash".
int magic_clearhint(SV* sv, MAGIC* mg)
magic_clearhints
Triggered by clearing %^H, resets
"PL_compiling.cop_hints_hash".
int magic_clearhints(SV* sv, MAGIC* mg)
magic_sethint
Triggered by a store to %^H, records the key/value
pair to "PL_compiling.cop_hints_hash". It is
assumed that hints aren't storing anything that
would need a deep copy. Maybe we should warn if we
find a reference.
int magic_sethint(SV* sv, MAGIC* mg)
mg_localize
Copy some of the magic from an existing SV to new
localized version of that SV. Container magic (eg
%ENV, $1, tie) gets copied, value magic doesn't (eg
taint, pos).
If setmagic is false then no set magic will be
called on the new (empty) SV. This typically means
that assignment will soon follow (e.g. 'local $x =
$y'), and that will handle the magic.
void mg_localize(SV* sv, SV* nsv, bool setmagic)
MRO Functions
mro_get_linear_isa_dfs
Returns the Depth-First Search linearization of @ISA
the given stash. The return value is a read-only
AV*. "level" should be 0 (it is used internally in
this function's recursion).
You are responsible for "SvREFCNT_inc()" on the
return value if you plan to store it anywhere semi-
permanently (otherwise it might be deleted out from
under you the next time the cache is invalidated).
AV* mro_get_linear_isa_dfs(HV* stash, U32 level)
mro_isa_changed_in
perl v5.12.5 Last change: 2014-06-17 7
Perl Programmers Reference Guide PERLINTERN(1)
Takes the necessary steps (cache invalidations,
mostly) when the @ISA of the given package has
changed. Invoked by the "setisa" magic, should not
need to invoke directly.
void mro_isa_changed_in(HV* stash)
Pad Data Structures
CvPADLIST
CV's can have CvPADLIST(cv) set to point to an AV.
For these purposes "forms" are a kind-of CV, eval""s
are too (except they're not callable at will and are
always thrown away after the eval"" is done
executing). Require'd files are simply evals without
any outer lexical scope.
XSUBs don't have CvPADLIST set - dXSTARG fetches
values from PL_curpad, but that is really the
callers pad (a slot of which is allocated by every
entersub).
The CvPADLIST AV has does not have AvREAL set, so
REFCNT of component items is managed "manual"
(mostly in pad.c) rather than normal av.c rules.
The items in the AV are not SVs as for a normal AV,
but other AVs:
0'th Entry of the CvPADLIST is an AV which
represents the "names" or rather the "static type
information" for lexicals.
The CvDEPTH'th entry of CvPADLIST AV is an AV which
is the stack frame at that depth of recursion into
the CV. The 0'th slot of a frame AV is an AV which
is @_. other entries are storage for variables and
op targets.
During compilation: "PL_comppad_name" is set to the
names AV. "PL_comppad" is set to the frame AV for
the frame CvDEPTH == 1. "PL_curpad" is set to the
body of the frame AV (i.e. AvARRAY(PL_comppad)).
During execution, "PL_comppad" and "PL_curpad" refer
to the live frame of the currently executing sub.
Iterating over the names AV iterates over all
possible pad items. Pad slots that are SVs_PADTMP
(targets/GVs/constants) end up having &PL_sv_undef
"names" (see pad_alloc()).
Only my/our variable (SVs_PADMY/SVs_PADOUR) slots
perl v5.12.5 Last change: 2014-06-17 8
Perl Programmers Reference Guide PERLINTERN(1)
get valid names. The rest are op
targets/GVs/constants which are statically allocated
or resolved at compile time. These don't have names
by which they can be looked up from Perl code at run
time through eval"" like my/our variables can be.
Since they can't be looked up by "name" but only by
their index allocated at compile time (which is
usually in PL_op->op_targ), wasting a name SV for
them doesn't make sense.
The SVs in the names AV have their PV being the name
of the variable. xlow+1..xhigh inclusive in the NV
union is a range of cop_seq numbers for which the
name is valid. For typed lexicals name SV is
SVt_PVMG and SvSTASH points at the type. For "our"
lexicals, the type is also SVt_PVMG, with the
SvOURSTASH slot pointing at the stash of the
associated global (so that duplicate "our"
declarations in the same package can be detected).
SvUVX is sometimes hijacked to store the generation
number during compilation.
If SvFAKE is set on the name SV, then that slot in
the frame AV is a REFCNT'ed reference to a lexical
from "outside". In this case, the name SV does not
use xlow and xhigh to store a cop_seq range, since
it is in scope throughout. Instead xhigh stores some
flags containing info about the real lexical (is it
declared in an anon, and is it capable of being
instantiated multiple times?), and for fake ANONs,
xlow contains the index within the parent's pad
where the lexical's value is stored, to make cloning
quicker.
If the 'name' is '&' the corresponding entry in
frame AV is a CV representing a possible closure.
(SvFAKE and name of '&' is not a meaningful
combination currently but could become so if "my sub
foo {}" is implemented.)
Note that formats are treated as anon subs, and are
cloned each time write is called (if necessary).
The flag SVs_PADSTALE is cleared on lexicals each
time the my() is executed, and set on scope exit.
This allows the 'Variable $x is not available'
warning to be generated in evals, such as
{ my $x = 1; sub f { eval '$x'} } f();
For state vars, SVs_PADSTALE is overloaded to mean
'not yet initialised'

Perl Programmers Reference Guide PERLINTERN(1)
AV * CvPADLIST(CV *cv)
cv_clone
Clone a CV: make a new CV which points to the same
code etc, but which has a newly-created pad built by
copying the prototype pad and capturing any outer
lexicals.
CV* cv_clone(CV* proto)
cv_dump dump the contents of a CV
void cv_dump(const CV *cv, const char *title)
do_dump_pad
Dump the contents of a padlist
void do_dump_pad(I32 level, PerlIO *file, PADLIST *padlist, int full)
intro_my
"Introduce" my variables to visible status.
U32 intro_my()
pad_add_anon
Add an anon code entry to the current compiling pad
PADOFFSET pad_add_anon(SV* sv, OPCODE op_type)
pad_add_name
Create a new name and associated PADMY SV in the
current pad; return the offset. If "typestash" is
valid, the name is for a typed lexical; set the
name's stash to that value. If "ourstash" is valid,
it's an our lexical, set the name's SvOURSTASH to
that value
If fake, it means we're cloning an existing entry
NOTE: this function is experimental and may change
or be removed without notice.
PADOFFSET pad_add_name(const char *name, const STRLEN len, const U32 flags, HV *typestash, HV *ourstash)
pad_alloc
Allocate a new my or tmp pad entry. For a my, simply
push a null SV onto the end of PL_comppad, but for a
tmp, scan the pad from PL_padix upwards for a slot
which has no name and no active value.
PADOFFSET pad_alloc(I32 optype, U32 tmptype)
perl v5.12.5 Last change: 2014-06-17 10
Perl Programmers Reference Guide PERLINTERN(1)
pad_block_start
Update the pad compilation state variables on entry
to a new block
void pad_block_start(int full)
pad_check_dup
Check for duplicate declarations: report any of:
* a my in the current scope with the same name;
* an our (anywhere in the pad) with the same
name and the same stash
as "ourstash" "is_our" indicates that the
name to check is an 'our' declaration
void pad_check_dup(SV *name, const U32 flags, const HV *ourstash)
pad_findlex
Find a named lexical anywhere in a chain of nested
pads. Add fake entries in the inner pads if it's
found in an outer one.
Returns the offset in the bottom pad of the lex or
the fake lex. cv is the CV in which to start the
search, and seq is the current cop_seq to match
against. If warn is true, print appropriate
warnings. The out_* vars return values, and so are
pointers to where the returned values should be
stored. out_capture, if non-null, requests that the
innermost instance of the lexical is captured;
out_name_sv is set to the innermost matched namesv
or fake namesv; out_flags returns the flags normally
associated with the IVX field of a fake namesv.
Note that pad_findlex() is recursive; it recurses up
the chain of CVs, then comes back down, adding fake
entries as it goes. It has to be this way because
fake namesvs in anon protoypes have to store in xlow
the index into the parent pad.
PADOFFSET pad_findlex(const char *name, const CV* cv, U32 seq, int warn, SV** out_capture, SV** out_name_sv, int *out_flags)
pad_fixup_inner_anons
For any anon CVs in the pad, change CvOUTSIDE of
that CV from old_cv to new_cv if necessary. Needed
when a newly-compiled CV has to be moved to a pre-
existing CV struct.
void pad_fixup_inner_anons(PADLIST *padlist, CV *old_cv, CV *new_cv)
pad_free
Free the SV at offset po in the current pad.
perl v5.12.5 Last change: 2014-06-17 11
Perl Programmers Reference Guide PERLINTERN(1)
void pad_free(PADOFFSET po)
pad_leavemy
Cleanup at end of scope during compilation: set the
max seq number for lexicals in this scope and warn
of any lexicals that never got introduced.
void pad_leavemy()
pad_new Create a new compiling padlist, saving and updating
the various global vars at the same time as creating
the pad itself. The following flags can be OR'ed
together:
padnew_CLONE this pad is for a cloned CV
padnew_SAVE save old globals
padnew_SAVESUB also save extra stuff for start of sub
PADLIST* pad_new(int flags)
pad_push
Push a new pad frame onto the padlist, unless
there's already a pad at this depth, in which case
don't bother creating a new one. Then give the new
pad an @_ in slot zero.
void pad_push(PADLIST *padlist, int depth)
pad_reset
Mark all the current temporaries for reuse
void pad_reset()
pad_setsv
Set the entry at offset po in the current pad to sv.
Use the macro PAD_SETSV() rather than calling this
function directly.
void pad_setsv(PADOFFSET po, SV* sv)
pad_swipe
Abandon the tmp in the current pad at offset po and
replace with a new one.
void pad_swipe(PADOFFSET po, bool refadjust)
pad_tidy
Tidy up a pad after we've finished compiling it:
* remove most stuff from the pads of anonsub
prototypes;
* give it a @_;
* mark tmps as such.
perl v5.12.5 Last change: 2014-06-17 12
Perl Programmers Reference Guide PERLINTERN(1)
void pad_tidy(padtidy_type type)
pad_undef
Free the padlist associated with a CV. If parts of
it happen to be current, we null the relevant
PL_*pad* global vars so that we don't have any
dangling references left. We also repoint the
CvOUTSIDE of any about-to-be-orphaned inner subs to
the outer of this cv.
(This function should really be called pad_free, but
the name was already taken)
void pad_undef(CV* cv)
Per-Interpreter Variables
PL_DBsingle
When Perl is run in debugging mode, with the -d
switch, this SV is a boolean which indicates whether
subs are being single-stepped. Single-stepping is
automatically turned on after every step. This is
the C variable which corresponds to Perl's
$DB::single variable. See "PL_DBsub".
SV * PL_DBsingle
PL_DBsub
When Perl is run in debugging mode, with the -d
switch, this GV contains the SV which holds the name
of the sub being debugged. This is the C variable
which corresponds to Perl's $DB::sub variable. See
"PL_DBsingle".
GV * PL_DBsub
PL_DBtrace
Trace variable used when Perl is run in debugging
mode, with the -d switch. This is the C variable
which corresponds to Perl's $DB::trace variable.
See "PL_DBsingle".
SV * PL_DBtrace
PL_dowarn
The C variable which corresponds to Perl's $^W
warning variable.
bool PL_dowarn
PL_last_in_gv
The GV which was last used for a filehandle input
operation. ("<FH>")
perl v5.12.5 Last change: 2014-06-17 13
Perl Programmers Reference Guide PERLINTERN(1)
GV* PL_last_in_gv
PL_ofsgv
The glob containing the output field separator -
"*," in Perl space.
GV* PL_ofsgv
PL_rs The input record separator - $/ in Perl space.
SV* PL_rs
Stack Manipulation Macros
djSP Declare Just "SP". This is actually identical to
"dSP", and declares a local copy of perl's stack
pointer, available via the "SP" macro. See "SP".
(Available for backward source code compatibility
with the old (Perl 5.005) thread model.)
djSP;
LVRET True if this op will be the return value of an
lvalue subroutine
SV Manipulation Functions
sv_add_arena
Given a chunk of memory, link it to the head of the
list of arenas, and split it into a list of free
SVs.
void sv_add_arena(char *const ptr, const U32 size, const U32 flags)
sv_clean_all
Decrement the refcnt of each remaining SV, possibly
triggering a cleanup. This function may have to be
called multiple times to free SVs which are in
complex self-referential hierarchies.
I32 sv_clean_all()
sv_clean_objs
Attempt to destroy all objects not yet freed
void sv_clean_objs()
sv_free_arenas
Deallocate the memory used by all arenas. Note that
all the individual SV heads and bodies within the
arenas must already have been freed.

SV-Body Allocation
sv_2num Return an SV with the numeric value of the source
SV, doing any necessary reference or overload
conversion. You must use the "SvNUM(sv)" macro to
access this function.
NOTE: this function is experimental and may change
or be removed without notice.
SV* sv_2num(SV *const sv)
Unicode Support
find_uninit_var
Find the name of the undefined variable (if any)
that caused the operator o to issue a "Use of
uninitialized value" warning. If match is true,
only return a name if it's value matches uninit_sv.
So roughly speaking, if a unary operator (such as
OP_COS) generates a warning, then following the
direct child of the op may yield an OP_PADSV or
OP_GV that gives the name of the undefined variable.
On the other hand, with OP_ADD there are two
branches to follow, so we only print the variable
name if we get an exact match.
The name is returned as a mortal SV.
Assumes that PL_op is the op that originally
triggered the error, and that PL_comppad/PL_curpad
points to the currently executing pad.
NOTE: this function is experimental and may change
or be removed without notice.
SV* find_uninit_var(const OP *const obase, const SV *const uninit_sv, bool top)
report_uninit
Print appropriate "Use of uninitialized variable"
warning
