I've upgraded the MTA of our DECstation-3100 running Ultrix4.3a to
|
||
|
|
postfix-19990317-pl05 and am sending you the patches I needed to get
|
||
|
|
it running under Ultrix.
|
||
|
|
|
||
|
|
...
|
||
|
|
|
||
|
|
o One of the bugs of Ultrix's /bin/sh is that shell-variables set in
|
||
|
|
arguments of `:' expand to garbage if expanded in here-documents.
|
||
|
|
Using a different shell helps. I needed to replace all calls of
|
||
|
|
``sh .../makedefs'' by ``$(SHELL) .../makedefs'' in all the
|
||
|
|
Makefile.in and am now able to use
|
||
|
|
|
||
|
|
make SHELL=/bin/sh5 or zsh.
|
||
|
|
|
||
|
|
...
|
||
|
|
|
||
|
|
o Ultrix's FD_SET_SIZE is 4096, but getdtablesize() returns 64 by
|
||
|
|
default, if not increased when building a new kernel. getrlimit()
|
||
|
|
doesn't know RLIMIT_NOFILE. This makes event_init() always log
|
||
|
|
the warning: `could allocate space for only 64 open files'.
|
||
|
|
|
||
|
|
I just reduced the threshold from 256 to 64, but this is not good.
|
||
|
|
The initial problem still remains: How to disable this warning on
|
||
|
|
Ultrix without making the source ugly?
|
||
|
|
|
||
|
|
[I have updated util/sys_defs.h, and by default set FD_SETSIZE to
|
||
|
|
100. This should be sufficient for a workstation. No-one would
|
||
|
|
run a major mail hub on Ultrix 4. -- Wietse]
