Bug ID: 7986
Summary: spamd fails when in directory with absolute pathname
length greater than 50
Product: Spamassassin
Version: 4.0.0
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: spamc/spamd
Assignee: dev@spamassassin.apache.org
Reporter: sid...@sidney.com
Target Milestone: Undefined
If you are running the installation tests in a directory whose absolute path
name is longer than about 50 characters, then spamd fails because the path it
uses to create a UNIX socket is prefixed by the absolute pathname of the
current directory, then goes to be another long string of characters that
exceeds the Linux maximum for sockets of 108 characters. I was in a directory
/home/sidney/ms004pre1 and ran make disttest which started by creating a
subdirectory named Mail-SpamAssassin-4.0.0 and running tests from a
subdirectory of that. The resulting error message and test failure in the spamd
tests was
May 4 23:43:28.831 [161340] dbg: spamd: creating UNIX socket:

exceeds system limit, exiting
spamd should create the socket in some temporary directory whose location is in
a shorter path instead of taking a chance on the current directory.
