Subject: [PATCH] Destroy {GDBM,NDBM,ODBM,SDBM}_File objects only from original
thread context
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch fixes a crash when destroing a hash tied to a *_File
database after spawning a thread:
use Fcntl;
use SDBM_File;
use threads;
tie(my %dbtest, 'SDBM_File', "test.db", O_RDWR|O_CREAT, 0666);
threads->new(sub {})->join;
This crashed or paniced depending on how perl was configured.
Closes RT#61912.

Subject: [PATCH] t/op/crypt.t: Perform SHA-256 algorithm if default one is
disabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The crypt(3) call may return NULL. This is the case of FIPS-enabled
platforms. Then "salt makes a difference" test would fail.
