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!
Compile-time scope hooks
BhkENTRY
Return an entry from the BHK structure. which is a preprocessor token indicating
which entry to return. If the appropriate flag is not set this will return NULL.
The type of the return value depends on which entry you ask for.
NOTE: this function is experimental and may change or be removed without notice.
void * BhkENTRY(BHK *hk, which)
BhkFLAGS
Return the BHK's flags.
NOTE: this function is experimental and may change or be removed without notice.
U32 BhkFLAGS(BHK *hk)
CALL_BLOCK_HOOKS
Call all the registered block hooks for type which. which is a preprocessing
token; the type of arg depends on which.
NOTE: this function is experimental and may change or be removed without notice.
void CALL_BLOCK_HOOKS(which, arg)
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 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)
Embedding Functions
cv_dump dump the contents of a CV
void cv_dump(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()
padlist_dup
Duplicates a pad.
AV * padlist_dup(AV *srcpad, CLONE_PARAMS *param)
pad_alloc_name
Allocates a place in the currently-compiling pad (via "pad_alloc" in perlapi) and
then stores a name for that entry. namesv is adopted and becomes the name entry;
it must already contain the name string and be sufficiently upgraded. typestash
and ourstash and the "padadd_STATE" flag get added to namesv. None of the other
processing of "pad_add_name_pvn" in perlapi is done. Returns the offset of the
allocated pad slot.
PADOFFSET pad_alloc_name(SV *namesv, U32 flags,
HV *typestash, HV *ourstash)
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 C<ourstash>
"is_our" indicates that the name to check is an 'our' declaration.
void pad_check_dup(SV *name, 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 *namepv,
STRLEN namelen, U32 flags,
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.
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_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_swipe
Abandon the tmp in the current pad at offset po and replace with a new one.
void pad_swipe(PADOFFSET po, bool refadjust)
Functions in file op.c
core_prototype
This function assigns the prototype of the named core function to "sv", or to a
new mortal SV if "sv" is NULL. It returns the modified "sv", or NULL if the core
function has no prototype. "code" is a code as returned by "keyword()". It must
be negative and unequal to -KEY_CORE.
SV * core_prototype(SV *sv, const char *name,
const int code,
int * const opnum)
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)
Hash Manipulation Functions
hv_ename_add
Adds a name to a stash's internal list of effective names. See "hv_ename_delete".
This is called when a stash is assigned to a new location in the symbol table.
void hv_ename_add(HV *hv, const char *name, U32 len,
U32 flags)
hv_ename_delete
Removes a name from a stash's internal list of effective names. If this is the
name returned by "HvENAME", then another name in the list will take its place
("HvENAME" will use it).
This is called when a stash is deleted from the symbol table.
void hv_ename_delete(HV *hv, const char *name,
U32 len, U32 flags)
refcounted_he_chain_2hv
Generates and returns a "HV *" representing the content of a "refcounted_he"
chain. flags is currently unused and must be zero.
HV * refcounted_he_chain_2hv(
const struct refcounted_he *c, U32 flags
)
refcounted_he_fetch_pv
Like "refcounted_he_fetch_pvn", but takes a nul-terminated string instead of a
string/length pair.
SV * refcounted_he_fetch_pv(
const struct refcounted_he *chain,
const char *key, U32 hash, U32 flags
)
refcounted_he_fetch_pvn
Search along a "refcounted_he" chain for an entry with the key specified by keypv
and keylen. If flags has the "REFCOUNTED_HE_KEY_UTF8" bit set, the key octets are
interpreted as UTF-8, otherwise they are interpreted as Latin-1. hash is a
precomputed hash of the key string, or zero if it has not been precomputed.
Returns a mortal scalar representing the value associated with the key, or
&PL_sv_placeholder if there is no value associated with the key.
SV * refcounted_he_fetch_pvn(
const struct refcounted_he *chain,
const char *keypv, STRLEN keylen, U32 hash,
U32 flags
)
refcounted_he_fetch_pvs
Like "refcounted_he_fetch_pvn", but takes a literal string instead of a
string/length pair, and no precomputed hash.
SV * refcounted_he_fetch_pvs(
const struct refcounted_he *chain,
const char *key, U32 flags
)
refcounted_he_fetch_sv
Like "refcounted_he_fetch_pvn", but takes a Perl scalar instead of a string/length
pair.
SV * refcounted_he_fetch_sv(
const struct refcounted_he *chain, SV *key,
U32 hash, U32 flags
)
refcounted_he_free
Decrements the reference count of a "refcounted_he" by one. If the reference
count reaches zero the structure's memory is freed, which (recursively) causes a
reduction of its parent "refcounted_he"'s reference count. It is safe to pass a
null pointer to this function: no action occurs in this case.
void refcounted_he_free(struct refcounted_he *he)
refcounted_he_inc
Increment the reference count of a "refcounted_he". The pointer to the
"refcounted_he" is also returned. It is safe to pass a null pointer to this
function: no action occurs and a null pointer is returned.
struct refcounted_he * refcounted_he_inc(
struct refcounted_he *he
)
refcounted_he_new_pv
Like "refcounted_he_new_pvn", but takes a nul-terminated string instead of a
string/length pair.
struct refcounted_he * refcounted_he_new_pv(
struct refcounted_he *parent,
const char *key, U32 hash,
SV *value, U32 flags
)
refcounted_he_new_pvn
Creates a new "refcounted_he". This consists of a single key/value pair and a
reference to an existing "refcounted_he" chain (which may be empty), and thus
forms a longer chain. When using the longer chain, the new key/value pair takes
precedence over any entry for the same key further along the chain.
The new key is specified by keypv and keylen. If flags has the
"REFCOUNTED_HE_KEY_UTF8" bit set, the key octets are interpreted as UTF-8,
otherwise they are interpreted as Latin-1. hash is a precomputed hash of the key
string, or zero if it has not been precomputed.
value is the scalar value to store for this key. value is copied by this
function, which thus does not take ownership of any reference to it, and later
changes to the scalar will not be reflected in the value visible in the
"refcounted_he". Complex types of scalar will not be stored with referential
integrity, but will be coerced to strings. value may be either null or
&PL_sv_placeholder to indicate that no value is to be associated with the key;
this, as with any non-null value, takes precedence over the existence of a value
for the key further along the chain.
parent points to the rest of the "refcounted_he" chain to be attached to the new
"refcounted_he". This function takes ownership of one reference to parent, and
returns one reference to the new "refcounted_he".
struct refcounted_he * refcounted_he_new_pvn(
struct refcounted_he *parent,
const char *keypv,
STRLEN keylen, U32 hash,
SV *value, U32 flags
)
refcounted_he_new_pvs
Like "refcounted_he_new_pvn", but takes a literal string instead of a
string/length pair, and no precomputed hash.
struct refcounted_he * refcounted_he_new_pvs(
struct refcounted_he *parent,
const char *key, SV *value,
U32 flags
)
refcounted_he_new_sv
Like "refcounted_he_new_pvn", but takes a Perl scalar instead of a string/length
pair.
struct refcounted_he * refcounted_he_new_sv(
struct refcounted_he *parent,
SV *key, U32 hash, SV *value,
U32 flags
)
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.
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_methcall
Invoke a magic method (like FETCH).
"sv" and "mg" are the tied thingy and the tie magic.
"meth" is the name of the method to call.
"argc" is the number of args (in addition to $self) to pass to the method.
The "flags" can be:
G_DISCARD invoke method with G_DISCARD flag and don't
return a value
G_UNDEF_FILL fill the stack with argc pointers to
PL_sv_undef
The arguments themselves are any values following the "flags" argument.
Returns the SV (if any) returned by the method, or NULL on failure.
SV* magic_methcall(SV *sv, const MAGIC *mg,
const char *meth, U32 flags,
U32 argc, ...)
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
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)
mro_package_moved
Call this function to signal to a stash that it has been assigned to another spot
in the stash hierarchy. "stash" is the stash that has been assigned. "oldstash"
is the stash it replaces, if any. "gv" is the glob that is actually being
assigned to.
This can also be called with a null first argument to indicate that "oldstash" has
been deleted.
This function invalidates isa caches on the old stash, on all subpackages nested
inside it, and on the subclasses of all those, including non-existent packages
that have corresponding entries in "stash".
It also sets the effective names ("HvENAME") on all the stashes as appropriate.
If the "gv" is present and is not in the symbol table, then this function simply
returns. This checked will be skipped if "flags & 1".
void mro_package_moved(HV * const stash,
HV * const oldstash,
const GV * const gv,
U32 flags)
Optree Manipulation Functions
finalize_optree
This function finalizes the optree. Should be called directly after the complete
optree is built. It does some additional checking which can't be done in the
normal ck_xxx functions and makes the tree thread-safe.
void finalize_optree(OP* o)
Pad Data Structures
CX_CURPAD_SAVE
Save the current pad in the given context block structure.
void CX_CURPAD_SAVE(struct context)
CX_CURPAD_SV
Access the SV at offset po in the saved current pad in the given context block
structure (can be used as an lvalue).
SV * CX_CURPAD_SV(struct context, PADOFFSET po)
PAD_BASE_SV
Get the value from slot "po" in the base (DEPTH=1) pad of a padlist
SV * PAD_BASE_SV(PADLIST padlist, PADOFFSET po)
PAD_CLONE_VARS
Clone the state variables associated with running and compiling pads.
void PAD_CLONE_VARS(PerlInterpreter *proto_perl,
CLONE_PARAMS* param)
PAD_COMPNAME_FLAGS
Return the flags for the current compiling pad name at offset "po". Assumes a
valid slot entry.
U32 PAD_COMPNAME_FLAGS(PADOFFSET po)
PAD_COMPNAME_GEN
The generation number of the name at offset "po" in the current compiling pad
(lvalue). Note that "SvUVX" is hijacked for this purpose.
STRLEN PAD_COMPNAME_GEN(PADOFFSET po)
PAD_COMPNAME_GEN_set
Sets the generation number of the name at offset "po" in the current ling pad
(lvalue) to "gen". Note that "SvUV_set" is hijacked for this purpose.
STRLEN PAD_COMPNAME_GEN_set(PADOFFSET po, int gen)
PAD_COMPNAME_OURSTASH
Return the stash associated with an "our" variable. Assumes the slot entry is a
valid "our" lexical.
HV * PAD_COMPNAME_OURSTASH(PADOFFSET po)
PAD_COMPNAME_PV
Return the name of the current compiling pad name at offset "po". Assumes a valid
slot entry.
char * PAD_COMPNAME_PV(PADOFFSET po)
PAD_COMPNAME_TYPE
Return the type (stash) of the current compiling pad name at offset "po". Must be
a valid name. Returns null if not typed.
HV * PAD_COMPNAME_TYPE(PADOFFSET po)
pad_peg When PERL_MAD is enabled, this is a small no-op function that gets called at the
start of each pad-related function. It can be breakpointed to track all pad
operations. The parameter is a string indicating the type of pad operation being
performed.
NOTE: this function is experimental and may change or be removed without notice.
void pad_peg(const char *s)
PAD_RESTORE_LOCAL
Restore the old pad saved into the local variable opad by PAD_SAVE_LOCAL()
void PAD_RESTORE_LOCAL(PAD *opad)
PAD_SAVE_LOCAL
Save the current pad to the local variable opad, then make the current pad equal
to npad
void PAD_SAVE_LOCAL(PAD *opad, PAD *npad)
PAD_SAVE_SETNULLPAD
Save the current pad then set it to null.
void PAD_SAVE_SETNULLPAD()
PAD_SETSV
Set the slot at offset "po" in the current pad to "sv"
SV * PAD_SETSV(PADOFFSET po, SV* sv)
PAD_SET_CUR
Set the current pad to be pad "n" in the padlist, saving the previous current pad.
NB currently this macro expands to a string too long for some compilers, so it's
best to replace it with
SAVECOMPPAD();
PAD_SET_CUR_NOSAVE(padlist,n);
void PAD_SET_CUR(PADLIST padlist, I32 n)
PAD_SET_CUR_NOSAVE
like PAD_SET_CUR, but without the save
void PAD_SET_CUR_NOSAVE(PADLIST padlist, I32 n)
PAD_SV Get the value at offset "po" in the current pad
void PAD_SV(PADOFFSET po)
PAD_SVl Lightweight and lvalue version of "PAD_SV". Get or set the value at offset "po"
in the current pad. Unlike "PAD_SV", does not print diagnostics with -DX. For
internal use only.
SV * PAD_SVl(PADOFFSET po)
SAVECLEARSV
Clear the pointed to pad value on scope exit. (i.e. the runtime action of 'my')
void SAVECLEARSV(SV **svp)
SAVECOMPPAD
save PL_comppad and PL_curpad
void SAVECOMPPAD()
SAVEPADSV
Save a pad slot (used to restore after an iteration)
XXX DAPM it would make more sense to make the arg a PADOFFSET
void SAVEPADSV(PADOFFSET po)
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>")
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.
void sv_free_arenas()
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)
sv_ref Returns a SV describing what the SV passed in is a reference to.
SV* sv_ref(SV *dst, const SV *const sv,
const int ob)
Unicode Support
find_uninit_var
Find the name of the undefined variable (if any) that caused the operator to issue
a "Use of uninitialized value" warning. If match is true, only return a name if
its 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.
void report_uninit(const SV *uninit_sv)
