[AOLSERVER] TCL 8.5 and ns_proxy segfault
Alexey Pechnikov
I did try to build AOL 4.5.1 with TCL 8.5. AOL is work, but nsproxy module now
doesn't work. nsproxy is simple but I don't understand why this doesn't work
:-(
$ /usr/lib/aolserver4/bin/nsproxy
Segmentation fault
I did copy strace for no-work nspoxy (TCL 8.5) and work (TCL 8.4).

nsproxy is being called.
The strace is not very informative. gdb is better. The stack trace below
indicates that the problem might point to a problem with the
thread associated data. GetData() in nsd/tclinit.c calls
Tcl_AsyncCreate(), which crashes when it tries to get the thread data.

to Tcl 8.5 and Alexey's problem.
nsproxy defines the structure Proxy as follows:
typedef struct Proxy {
....
char id[16]; /* Proxy unique string id. */
Proc *procPtr; /* Running child process, if any. */
....
} Proxy;
later, the id is initialized by
sprintf(proxyPtr->id, "%s-proxy-%d", poolPtr->name, poolPtr->nextid++);
The sprintf will cause a problem, if the pool name has more than 16-9 =
7 bytes.
Since pool name is passed in via tcl, and its length is not checked,
wierd things
are likely to happen (the procPtr will be overwritten).
For example, OpenACS does a
set handle [ns_proxy get exec_proxy]
where len(exec_proxy)>7.
The quick fix is to change char id[16] to id[32], but actually, one should
check the length...
Unfortunately, this does not help in the original problem.

Don't know if he compiled it himself, or used it to compile AOLserver.
But in this case, the symptom is usually very strange and random
segfaults.

below is a fix for the nsproxy problem that you reported.
The problem comes from a different initialization semantics
in Tcl 8.5, that hits the nsproxy binary. The added call
should work with Tcl 8.4 as well; please report back
such i can commit the fix to CVS.
best regards

Patch really did solve the problem. I did test AOL4.5.1+Tcl8.5.6 build on one
my low-loaded productions server by 4 hour now and this work. Thank you very
much!
But I did find a few additional problems:
1. Some queries to nsproxy processes may produce zombie:

The problem is exists as for tcl8.5 as tcl8.4 builds of AOL+nsproxy.
2. Proxy processes have infinite live time and "waittimeout" is ignored.
I did start nsproxy some days ago on my production server and one process
exists now (tcl 8.4).
Now I'm testing nsproxy with tcl 8.5.
I did try
ns_proxy config myproxy -max 1 -getimeout 2000 -evaltimeout 4000
And I'm get result as:

But default waittimeout must be equal to 100ms as described in
http://panoptic.com/wiki/aolserver/Nsproxy
And I did try
ns_proxy config myproxy -max 1 -getimeout 2000 -evaltimeout 4000 -waittimeout
1000

So waittimeout is ignored. Am I right?
APD page code have section
ns_adp_puts [\
with-proxy myproxy {
puts "proxy pid: [ns_info pid]"
}]
puts "main pid: [ns_info pid]"
I did write wrapper for proxy as
proc with-proxy {proxy code} {
set handle [ns_proxy get $proxy]
set result [ns_proxy eval $handle $code]
ns_proxy release $handle
return $result
}
Infinite live time for proxy process is not problem but this behaviour is not
equal to documented.
Best regards.

It might be a good idea to report the two bugs on the tracker to keep
them on the radar
