[perl #81032] Overhaul Porting/epigraphs.pod

This patch makes multiple changes to Porting/epigraphs.pod and
pod/perlhist.pod.

For those that don't know, Porting/epigraphs.pod is a new document that
collects the quotes (chosen by Pumpkins) in perl release announcements.

The changes are the following.

1. Add a link pointing to each release announcement in the mailing
list archives.  These are from ysth's list, the source from which
Porting/epigraphs.pod was originally compiled, but they weren't in
Porting/epigraphs.pod so far.
2. Reorder Porting/epigraphs.pod chronologically, because I believe
that makes more sense -- pod/perlhist.pod is still sorted by version numbers.
3. Incidentally, some missing releases are added to pod/perlhist.pod too.
4. Fix a mistake where Porting/epigraphs.pod gives the wrong version number.
5. Add some epigraphs that appear in ysth's list but not in
Porting/epigraphs.pod.
6. I did some research in perl history before the part that ysth's list
covers, and added older perl announcements I found.  This work is not
complete: I stopped somewhere in 2000.

are not DESTROYed.

This commit adds a new visit() call to sv_clean_objs, which curses
(DESTROYs and un-blesses, leaving the reference count as it is) any
objects that are still left after do_clean_named_io_objs. The new

do_clean_named_io_objs’ example and explicitly skips the STDOUT and
STDERR handles, in case destructors need to use them.

sv_clear and put in its own routine. The check that the reference
count is zero does not apply when called from sv_clean_objs, so the

8 years agoBetter handling of magic methods freeing the SV
David Mitchell [Thu, 30 Dec 2010 10:32:44 +0000 (10:32 +0000)] 
Better handling of magic methods freeing the SV

This is a fix for RT #81230 (and more). Currently, mg_get() works around
the case where the called magic (e.g. FETCH) frees the magic SV. It does
this by unconditionally pushing the SV on the tmps stack before invoking
the method.

There are two issues with this. Firstly, it may artificially extend the
life of the SV. This was the root of the problem with #81230. There, the
DB_File code, under -T, created a tainted tied object. Accessing the
object (within FETCH as it happens), caused mg_get() to be invoked on the
object (due to the taint magic), and thus extend the life of the object.
This then caused c<untie %h if $h{k}> to give the warning
    untie attempted while 1 inner references still exist.
This only became noticeable after efaf36747029c85b4d8825318cb4d485a0bb350e,
which stopped wrapping magic method calls in SAVETMPS/FREETMPS.

The second issue issue that this protection only applies to mg_get();
functions like mg_set() can still segfault if the SV is deleted.

This commit fixes both problems as follows:

First, the protection mechanism is moved out of mg_get() and into
save_magic() / restore_magic(), so that it protects more things.
Secondly, the protection is now:

* in save_magic(), SvREFCNT_inc() the SV, thus protecting it from being
  freed during FETCH (or whatever)

* in restore_magic(), SvREFCNT_dec() the SV, undoing the protection
  without extending the life of the SV, *except* if the refcount is
  1 (ie FETCH tried to free it), then push it on the mortals stack
  to extend it life a bit so our callers wont choke on it.

Why: The Math::BigFloat->bcmp() method returns the wrong result when the

scalar. In such cases, bcmp() returns 0 because it fails to distinguish
between the two exponents.

How: With this fix, bcmp() does not convert the exponents to Perl
numerical scalars, but keeps them as arbitrary precision integers, thus
returning the correct result regardsless of the number of digits in the

Fix RT 25274: Math::BigInt::Calc->_num() overflow.

Why: Math::BigInt::Calc->_num() converts a big integer (in the internal
format) to a Perl scalar. If the big integer is too large to be
represented as a Perl scalar, it might return a Perl scalar numeric
"nan", rather than "inf". The reason is that the current algorithm might
multiply "inf" by "0", giving a "nan" which propagates. The following
example illustrates the bug:

    perl -MMath::BigInt=lib,Calc -wle \
        'print Math::BigInt->new("1e999999")->numify()'

How: This fix computes the output in a different way, never multiply
"inf" by "0".

Test: It is not obvious to me how to test this automatically in a
portable way, since Perl has no standard way of stringifying a scalar
numeric infinity. However the desired behaviour is verified manually and
