Summary: "spamassassin" script needs a SIGPIPE handler
Product: Spamassassin
Version: SVN Trunk (Latest Devel Version)
Platform: Other
OS/Version: other
Status: NEW
Severity: minor
Priority: P5
Component: spamassassin
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
by email regarding bug 5557, Per Kristian Hove noted:
'Hi again. I've attached a backtrace (backtrace.txt) of spamassassin
when this bug [the failure to remove tmp files] occurs.
The backtrace is produced from (and the line numbers relative to)
spamassassin 3.2.3 patched with the attached patch (debug.diff).
Spamassassin was run with TMPDIR set to "./debug".
Installing a signal handler in bin/spamassassin that ignores SIGPIPE
hides/cures the bug.'

my comments:
it appears that Per is therefore running the "spamassassin" command-line script,
and that script is failing to call ->finish() on a SIGPIPE. it should catch
SIGPIPEs and clear up appropriately.
