Make PerlIO marginally reentrant

Currently if an operation on a file handle is interrupted, and if
the signal handler accesses that same file handle (e.g. closes it),
then perl will crash. See [perl #75556].

This commit provides some basic infrastructure to avoid segfaults.
Basically it adds a lock count field to each handle (by re-purposing the
unused flags field in the PL_perlio array), then each time a signal
handler is called, the count is incremented. Then various parts of PerlIO
use a positive count to change behaviour. Most importantly, when layers
are popped, the PerlIOl structure is cleared, but not freed, and is left
in the chain of layers. This means that callers still holding pointers to
the various layers won't access freed structures. It does however mean
that PerlIOl structs may be leaked, and possibly slots in PL_perlio. But
this is better than crashing.

example, a buffer that has already been written once might get written
again. Fixing this sort of thing would require a large-scale audit of

make PL_perlio an array of PerlIOl, not PerlIO *

Layers in PerlIO are implemented as a linked list of PerlIOl structs;
eaxch one has a 'next' field pointing to the next layer. Now here's the
clever bit: When PerlIO* pointers are passed around to refer to a
particular handle, these are actually pointers to the 'next' field of the
*parent* layer (so to access the flags field say of a PerlIOl, you have to
double-defref it, e.g. (*f)->flags). The big advantage of this is that
it's easy for a layer to pop itself; when you call PerlIO_pop(f), f is a
pointer to the parent's 'next' field, so pop(f) can just do
*f = (*f)->next.

This means that there has to be a fake 'next' field above the topmost
layer. This is where PL_perlio comes in: it's a pointer to an arena of
arrays of pointers, each one capable of pointing to a PerlIOl structure.
When  a new handle is created, a spare arena slot is grabbed, and the
address of that slot is returned. This also allows for a handle with no

What this commit does is change PL_perlio from being an array of
PerlIO* into an array of PerlIOl structures - i.e. each element in the
array goes from being a single pointer, to having several fields. These
will be made used of in follow-up commits.

Stop eval "BEGIN{die}" from leaking

eval "BEGIN{die}" creates a *{"_<(eval 1)"} glob regardless of $^P’s
setting in non-threaded builds as of change f9bddea (5.12.0).

Notice that, for non-threaded builds, BEGIN{die} goes from never sav-

commit f9bddea7d2a0d824366014c8ee6ba57e7dedd8c3
Author: Nicholas Clark <>
Date:   Tue Dec 2 20:43:58 2008 +0000

    Implement PERLDBf_SAVESRC_INVALID, which saves source lines for string
    evals that fail to compile.

    p4raw-id: //depot/perl@34985

It stops unconditionally using the scoping mechanism to delete
$::{"_<(eval $num)"} on compilation failure:

-    safestr = savepvn(tmpbuf, len);
-    SAVEDELETE(PL_defstash, safestr, len);

but instead does it explicitly in this block:

+    if (doeval(gimme, NULL, runcv, seq)) {
+ if (was != PL_breakable_sub_gen /* Some subs defined here. */
+     /* Retain the filegv we created.  */
+ } else {
+     char *const safestr = savepvn(tmpbuf, len);
+     SAVEDELETE(PL_defstash, safestr, len);
+ }
+ return DOCATCH(PL_eval_start);
+    } else {
+ /* We have already left the scope set up earler thanks to the LEAVE
+    in doeval().  */
+     /* Retain the filegv we created.  */
+ } else {
+     (void)hv_delete(PL_defstash, tmpbuf, len, G_DISCARD);
+ }
+ return PL_op->op_next;
+    }

In the case of BEGIN{die}, that doeval() never returns, so the
clean-up code is not reached.

S_doeval never returns because call_list calls Perl_croak if it
catches a BEGIN error (appending the extra ‘BEGIN failed--compilation
aborted’, etc.). That takes execution all the way back to perl_run, so
it bypasses the clean-up code in pp_entereval.

What’s leaking is the GV created earlier in pp_entereval by this line:

    CopFILE_set(&PL_compiling, tmpbuf+2);

CopFILE_set simply stores a string under threads, but creates a GV
under non-threaded builds.

This commit solves the problem by scheduling a deletion *before* call-
ing doeval, if the source lines have not been saved.

This works because the usual code to handle it is only bypassed when
there is a BEGIN block (a subroutine), so PL_breakable_sub_gen will
have gone up. So we never need to delete the saved lines when that
code is bypassed.
