+=head1 NAME
+
+ExtUtils::MM::Utils - ExtUtils::MM methods without dependency on ExtUtils::MakeMaker
+
+=head1 SYNOPSIS
+
+    require ExtUtils::MM::Utils;
+    MM->maybe_command($file);
+
+=head1 DESCRIPTION
+
+This is a collection of L<ExtUtils::MM> subroutines that are used by many
+other modules but that do not need full-featured L<ExtUtils::MakeMaker>. The
+issue with L<ExtUtils::MakeMaker> is it pulls in Perl header files and that is
+an overkill for small subroutines.
+
+An example is the L<IPC::Cmd> that caused installing GCC just because of
+three-line I<maybe_command()> from L<ExtUtils::MM_Unix>.
+
+The intentions is to use L<ExtUtils::MM::Utils> instead of
+L<ExtUtils::MakeMaker> for these trivial methods. You can still call them via
+L<MM> class name.
+
+=head1 METHODS
+
+=over 4
+
+=item maybe_command
+
+Returns true, if the argument is likely to be a command.
+
+=cut
+
+if (!exists $INC{'ExtUtils/MM.pm'}) {
+    *MM::maybe_command = *ExtUtils::MM::maybe_command = \&maybe_command;
+}
+
+sub maybe_command {
+    my($self,$file) = @_;
+    return $file if -x $file && ! -d $file;
+    return;
+}
+
+1;
+
+=back
+
+=head1 BUGS
+
+These methods are copied from L<ExtUtils::MM_Unix>. Other operating systems
+are not supported yet. The reason is this
+L<a hack for Linux
+distributions|https://bugzilla.redhat.com/show_bug.cgi?id=1129443>.

+Subject: [PATCH] hints/linux: Add -lphtread to lddlflags
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Passing -z defs to linker flags causes perl to fail to build if threads are
+enabled:
+
+gcc  -shared -Wl,-z,relro -Wl,-z,defs -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -L/usr/local/lib -fstack-protector-strong Bzip2.o  -o ../../lib/auto/Compress/Raw/Bzip2/Bzip2.so  \
+   -L/usr/lib64 -lbz2 "-L../.." -lperl   \
+
+Bzip2.o: In function `deRef':
+/builddir/build/BUILD/perl-5.26.1/cpan/Compress-Raw-Bzip2/Bzip2.xs:256: undefined reference to `pthread_getspecific'
+
+The reason is Bzip2.xs calls dTHX macro included from thread.h via perl.h that
+expands to pthread_getspecific() function call that is defined in pthread
+library. But the pthread library is not explicitly linked to Bzip.so (see the
+gcc command). This is exactly what -z defs linker flag enforces.
+
+Underlinking ELFs can be dangerous because in case of versioned
+symbols it can cause run-time binding to an improper version symbol or
+even to an symbold from different library.
+
+This patch fixes hints for Linux by adding -lpthreads to lddlflags. It
+also adds -shared there because Configure.sh adds it only hints return
+lddlflags empty.

+Subject: [PATCH] PATCH: [perl #134329] Use after free in regcomp.c
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+A compiled regex is composed of nodes, forming a linked list, with
+normally a maximum of 16 bits used to specify the offset of the next
+link.  For patterns that require more space than this, the nodes that
+jump around are replaced with ones that have wider offsets.  Most nodes
+are unaffected, as they just contain the offset of the next node, and
+that number is always small.  The jump nodes are the ones affected.
+
+When compiling a pattern, the 16 bit mechanism is used, until it
+overflows, at which point the pattern is recompiled with the long jumps
+instead.
+
+When I rewrote the compiler last year to make it generally one pass, I
+noticed a lot of the cases where a node was added didn't check if the
+result overflowed (the function that does this returns FALSE in that
+case).  I presumed the prior authors knew better, and did not change
+things, except to put in a bogus value in the link (offset) field that
+should cause a crash if it were used.  That's what's happening in this
+ticket.
+
+But seeing this example, it's clear that the return value should be
+checked every time, because you can reach the limit at any time.  This
+commit changes to do that, and to require the function's return value to
+not be ignored, to guard against future changes.
+
+My guess is that the reason it generally worked when there were multiple
+passes is that the first pass didn't do anything except count space, and
+that at some point before the end of the pass the return value did get
+checked, so by the time the nodes were allocated for real, it knew
+enough to use the long jumps.

+Subject: [PATCH] Remove undefined behavior from IV shifting
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+It is undefined behavior to shift a negative integer to the left.  This
+commit avoids that by treating the value as unsigned, then casting back
+to integer for return.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The hexfp code doesn't check that the shift is 4, and so also
+accepts binary and octal fp numbers.
+
+Unfortunately the call to S_new_constant() always passed a prefix
+of 0x, so overloading would be trying to parse the wrong number.
+
+Another option is to simply allow only hex floats, though some work
+was done in 131894 to improve oct/bin float support.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Essentially the same code was being used in three places, and had
+undefined C behavior for some inputs.
+
+This consolidates the code into one inline function, and rewrites it to
+avoid undefined behavior.

+
+This breaks hooking the filetest ops' check function by modules like
+bareword::filehandles.  Instead use the OP_IS_FILETEST() macro to decide
+check for filetest ops.  Also add an OP_IS_STAT() macro for when we want
+to check for (l)stat as well as the filetest ops.

+
+This was due to a logic error on my part.  We need to save and restore a
+value.  Instead, it was getting restored to the wrong value.
+
+This particular instance of the bug was outputting a fatal error
+message, so that the only harm is not giving the user the correct info,
+and creating unnecessary work for them and us when it gets reported.
+But this bug could manifest itself when trying to output just a warning
+that the program otherwise would carry on from.

+Subject: [PATCH] S_scan_const() Properly test if need to grow
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+As we parse the input, creating a string constant, we may have to grow
+the destination if it fills up as we go along.  It allocates space in an
+SV and populates the string, but it doesn' update the SvCUR until the
+end, so in single stepping the debugger through the code, the SV looks
+empty until the end.  It turns out that as a result SvEND also doesn't
+get updated and still points to the beginning of the string until SvCUR
+is finally set.  That means that the test changed by this commit was
+always succeeding, because it was using SvEND that didn't get updated,
+so it would attempt to grow each time through the loop.  By moving a
+couple of statements earlier, and using SvLEN instead, which does always
+have the correct value, those extra growth attempts are avoided.

+Subject: [PATCH] (perl #122112) a simpler fix for pclose() aborted by a signal
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This change results in a zombie child process for the lifetime of
+the process, but I think that's the responsibility of the signal
+handler that aborted pclose().
+
+We could add some magic to retry (and retry and retry) waiting on
+child process as we rewind (since there's no other way to remove
+the zombie), but the program has chosen implicitly to abort the
+wait() done by pclose() and it's best to honor that.
+
+If we do choose to retry the wait() we might be blocking an attempt
+by the process to terminate, whether by exit() or die().
+
+If a program does need more flexible handling there's always
+pipe()/fork()/exec() and/or the various event-driven frameworks on
+CPAN.

+MIME-Version: 1.0

+
+This undoes some of the effect of f1000aa2d in that TO will always
+be supplied to CORE::send() if it's supplied, otherwise whether
+TO is supplied to CORE::send() is based on whether the socket is
+connected.
+
+On Linux you appear to be able to sendto() to a different address on
+a connected UDP socket, but this doesn't appear to be portable,
+failing on darwin, and presumably on other BSDs.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+subs in main:: are stored as a RV referring to a CV as a space
+optimization, but the pp_refassign code expected to find a glob,
+which made the assignment a no-op.
+
+Fix this by upgrading the reference to a glob in the refassign check
+function.
+
+Note that this would be an issue in other packages if 1e2cfe157ca
+was reverted (allowing the space savings in other packages too.)

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+RT #134275
+
+When the 'uninitialized warning' code in S_find_uninit_var() comes
+across an OP_MULTIDEREF node, it scans it to see if any part of that op
+(e.g. the indices or the returned value) could have been the source of
+the uninitialized value which triggered the warning.  Unfortunately when
+getting an AV or HV from a GV, it wasn't checking whether gp_av/gp_hv
+contained a NULL value. If so, it would SEGV.
+
+The test code is a bit contrived; you have to "pull the rug" from under
+the GV at just the right moment with *foo = *bar, then trigger an uninit
+warning on an op whose subtree includes an OP_MULTIDEREF.

+ VMS
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+VMS doesn't allow you to delete an open file like POSIXish systems
+do, but you can mark a file to be deleted once it's closed, but
+only when you open it.
+
+Since VMS doesn't (yet) have mkostemp() we can add our own flag to
+our mkostemp() emulation to pass the necessary magic to open() call
+to delete the file on close.

+        $dv->dumpValue([$x, $y]);
+
+and
+
+        $dv->dumpValues($x, $y);
+
+was not being sustained in the case where one of the elements in the
+array (or array ref) was undefined.  This was due to an insufficiently
+precise specification within the dumpValues() method for determining
+when the value "undef\n" should be printed.
+
+Tests for previously untested cases have been provided in
+t/rt-134441-dumpvalue.t.  They were not appended to t/Dumpvalue.t (as
+would normally have been the case) because the tests in that file have
+accreted over the years in a sub-optimal manner:  changes in attributes
+of the Dumpvalue object are tested but those changes are not zeroed-out
+(by, e.g., use of 'local $self->{attribute} = undef')
+before additional attributes are modified and tested.  As a consequence,
+it's difficult to determine the state of the Dumpvalue object at any
+particular point and interactions between attributes cannot be ruled
+out.
+
+Package TieOut, used to capture STDOUT during testing, has been
+extracted to its own file so that it can be used by all test files.

+Subject: [PATCH] Adapt Configure to GCC version 10
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+I got a notice from Jeff Law <law@redhat.com>:
+
+    Your particular package fails its testsuite. This was ultimately
+    tracked down to a Configure problem. The perl configure script treated
+    gcc-10 as gcc-1 and turned on -fpcc-struct-return. This is an ABI
+    changing flag and caused Perl to not be able to interact properly with
+    the dbm libraries on the system leading to a segfault.
+
+His proposed patch corrected only this one instance of the version
+mismatch. Reading the Configure script revealed more issues. This
+patch fixes all of them I found.
+
+Please note I did not test it because I don't have GCC 10 available.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Most linux systems rarely update atime, so it's very unlikely
+for this issue to trigger there, but on a system with classic atime
+behaviour this was a race between open modifying atime and time()
+ticking over.

+Subject: [PATCH] toke.c: Fix bug tr/// upgrading to UTF-8 in middle
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Consider tr/\x{ff}-\x{100}/AB/.
+
+While parsing, the code keeps an offset from the beginning of the output
+to the beginning of the second number in the range.  This is purely for
+speed so that it wouldn't have to re-find the beginning of that value,
+when it already knew it.
+
+But the example above shows the folly of this shortcut.  The second
+number in the range causes the output to be upgraded to UTF-8, which
+makes that offset invalid in general.  Change to re-find the beginning.

+The Fedora perl MakeMaker distribution differs from the standard
+upstream release in that it disables use of the MakeMaker generated
+LD_RUN_PATH by default, UNLESS this attribute is specified , or the
+USE_MM_LD_RUN_PATH environment variable is set during the MakeMaker run.
+
+The upstream MakeMaker will set the ld(1) environment variable LD_RUN_PATH
+to the concatenation of every -L ld(1) option directory in which a -l ld(1)
+option library is found, which is used as the ld(1) -rpath option if none
+is specified. This means that, if your application builds shared libraries
+and your MakeMaker application links to them, that the absolute paths of the
+libraries in the build tree will be inserted into the RPATH header of all
+MakeMaker generated binaries, and that such binaries will be unable to link
+to these libraries if they do not still reside in the build tree directories
+(unlikely) or in the system library directories (/lib or /usr/lib), regardless
+of any LD_LIBRARY_PATH setting. So if you specified -L../mylib -lmylib , and
+ your 'libmylib.so' gets installed into /some_directory_other_than_usr_lib,
+ your MakeMaker application will be unable to link to it, even if LD_LIBRARY_PATH
+is set to include /some_directory_other_than_usr_lib, because RPATH overrides
+LD_LIBRARY_PATH.
+
+So for Fedora MakeMaker builds LD_RUN_PATH is NOT generated by default for
+every link. You can still use explicit -rpath ld options or the LD_RUN_PATH
+environment variable during the build to generate an RPATH for the binaries.
+
+You can set the USE_MM_LD_RUN_PATH attribute to 1 on the MakeMaker command
+line or in the WriteMakefile arguments to enable generation of LD_RUN_PATH
+for every link command.
+
+USE_MM_LD_RUN_PATH will default to 1 (LD_RUN_PATH will be used) IF the
+$USE_MM_LD_RUN_PATH environment variable is set during a MakeMaker run.
