Re: [AOLSERVER] Getting a handle on memory usage
Let me add my 2 cents as well as i have spent a lot of time trying to deal with ever-growing nsd process. Currently i have nsd process (Naviserver) with size about 500Mb running without restart for 15 days. Tcl compiled without Zippy, with standard malloc-family. I tried it with vtmalloc as well, the difference is not big, it gets shrinked faster but overall size-wise it is similar to just standard Linux malloc. The only bug change i had to make to Naviserver is to intriduces timeout and max number of jobs to execute to the Tcl job facility and to scheduling thread. Conn threads are controlled by maxconn and etc, DB handles have idle and config parameters when to close connections. the only missing part was to let sched and tcljob cleanup their resources. For example i use a lot ns_job and sch_schedXXX, that measn all Tcl interps allocted by sched and job threads stay forever and grow unconditionally. But with limits and config parameters that tell those threads when to exit work perfectly. Hope those changes may be useful for aolserver code as well. Maurizio Martignano wrote: Dear all, Sometime ago I made some tests on the memory leaks of aolserver+tcs+openacs. I'd like to share my two cents worth of what I believe I found, hoping it might help. Aolserver uses TCL, and TCL's got three different memory managers: 1. Standard: using the malloc, free, etc... primitives of the OS (not so fast and not using a lot of memory) 2. Zippy: multithreaded primitives specially developed for TCL (very fast but using plenty of memory - this is the default mechanism) 3. VTMalloc: another multithreaded implementation, developed by third parties, and somehow in between Standard and Zippy for what concerns efficiency and memory occupation. When using Zippy I noticed that the memory occupied by Aolserver (nsd) always grows, without being released. On the contrary when using the Standard memory allocator every now and then memory gets released when not used. The total memory occupied by Aolserver keeps growing but at a slower pace that in the previous case. How to enable TCL Standard memory allocator? Just call the following configure command: configure -enable-threads Then edit the Makefile, look for AC_FLAGS and remove from it the -DUSE_THREAD_ALLOC=1 define (i.e. delete the string -DUSE_THREAD_ALLOC=1). Compile everything, and see how it goes With this change in place, I've seen some saving on the memory occupied by nsd (around 30%). Another point to look at very carefully is the overall system configuration (config.tcl): Parameters like maxconnections maxdropped maxthreads minthreads threadtimeout and maxidle maxopen connections1 have quite an effect on the total occupied memory. Here there's no general recipe. My suggestion would be try to use the smallest possible values that still allow the system to work.

Re: [AOLSERVER] nsfreetds
Thank you, i was experimenting yesterday and i think i got it working
right, but with 0.64+ version.
With versions 0.63+ DB_Cancel should call
tds_process_simple_query to clear pending results, tds_freeall_resulst
does not do this.

The severity level of an error message provides an indication of the

Severity level 10 messages are informational and indicate problems
caused by mistakes in the information you have entered. Severity
levels from 11 through 16 are generated by the user, and can be
corrected by the user.
I remember experimenting and finding that it was safe to consider
error levels 1 - 10 Notice information and 10 always indicating a

Vlad,

It seems to work fine, but has a glitch I ran into as well which is
that it doesn't return error codes when something went wrong with the

SQL:
SELECT cast('foo' as int)
Results:
error: Database operation exec failed (exception NSDB, Syntax

Rows affected: -1
With your version I get

This has to do with a fundamental change in error handling where
non-network communication errors are not errors to freetds anymore.
They are simply passed back to the application for it to handle.

Vlad,

It seems to work fine, but has a glitch I ran into as well which is
that it doesn't return error codes when something went wrong with the

SQL:
SELECT cast('foo' as int)
Results:
error: Database operation exec failed (exception NSDB, Syntax
error converting the varchar value 'foo' to a column of data type

Rows affected: -1
With your version I get

This has to do with a fundamental change in error handling where
non-network communication errors are not errors to freetds anymore.
They are simply passed back to the application for it to handle.
Here is my hack which seems to work but may be terribly wrong for other reasons.

Re: [AOLSERVER] Asterisk and AOLserver
While reading the previous postings I stumbled upon multiple mentioning of multi protocol support and asterisk, therefore I assume people on this list are knowledgeable about this topic. Here is what we need: We run a CRM system on top of AOLserver. The CRM system contains the phone numbers of the clients. I want my PBX connected phone to make a connection to the client if I click on a link in the CRM System. Once the phone call is finished, the CRM system should be notified about this, so it can add a new entry in the call history. Same goes the other way round, if the client calls me, the CRM systems starts logging and once finished, an entry is added. Any clues, hints, offers, suggestions, RTFM advises on how to achieve this ? I did not reach that point yet, i just implemented UDP support and SIP module and perform SIP redirects using flexible rules where to forward the call. The functionality you are looking for will depend on your PBX, how you can place or receive calls. In case of VoIP you have more options than with traditional PSDN PBX, you can use softphone to initiate and receive calls, and using SIP you can easily forward calls to next available CSR. But this is a lot of work, i did not see anything yet in the open source. -- AOLserver - http://www.aolserver.com/ To Remove yourself from this list, simply send an email to [EMAIL PROTECTED] with the body of SIGNOFF AOLSERVER in the email message.

Re: [AOLSERVER] AOLserver facelift.
So, for a moment, ignore the existance of AOL. What does the rest of the AOLserver Community think about your patches? I don't mean people just saying oh, we think Vlad's patches are great -- I mean, who else has written code that needs to run on a version of AOLserver built with your patches? (This is my actions speak louder than words principle.) If no code nobody will use it, it needs to be developed first and then other people will notice it and may try it. For example, i made binder to support all kinds of sockets, not just TCP, UDP/UNIX/RAW. Before if you need UDP server you will have to write module or separate process, now you can use AS API. This give opportunities for others to develop different applications, not Web apps but server apps. Please explain what the difference is between being just a webserver and being a full-blown application server. Isn't a web server that serves web applications, by definition, a kind of application server? By virtue of its name, at minimum a web application server? By application server i mean you can built not only web applications, more exactly, the server does not necessary accepts only HTTP requests. This is, of course, the benefit of having a very flexible, easily extendable and highly modular architecture. Only stuff that needs to be part of the core in order to function should go there. And, as time goes on, you may likely see even more and more functionality come out of the AOLserver core into their own independent modules. It's been 5 years and we still have same AOLserver distirbution since 3.3.1, same functionality, it took how long to accept aD patches into mainline? A list of contributed AOLserver modules (for lack of a better name) has been up on the wiki for a while: http://panoptic.com/wiki/aolserver/Modules Many of the modules listed were not developed by AOL! That's a significant contribution from outside of AOL, for a project that so many people criticize as not being friendly to non-AOL contributions. Is the argument here that those modules should be integrated into the core? Do you really think that makes sense? I'm all in favor for an even more lightweight core, but maybe others aren't? I contributed myself 12 modules (i have more in my repository) and they are active, but that's my point exactly, if you have to implement something not simple or different as AS module, AOLServer architecture does not allow you to do this without changing the core. On ther hand, not everybody needs it, maybe only 1% from all users will need from AS non-web only functionality, so, may be keeping core as is would be the best thing and having only one version in the SF. Maybe completley different version/fork with its own plans and not associated with AOLserver is the only way? I was not trying to break AOLServer community, that was my personall opinion and actually i do not expect anything from AOL or Core developers, i am sorry if i offended somebody. I will continue to use AOLserver, extend it, keep my patches and contributing new modules. I just gave up participating in SF tracker thing. -- AOLserver - http://www.aolserver.com/ To Remove yourself from this list, simply send an email to [EMAIL PROTECTED] with the body of SIGNOFF AOLSERVER in the email message.

Re: [AOLSERVER] AOLserver facelift.
Oh yes! See, our app is written entirely arround it and the web-part is about 20% of the total (the web-based config GUI). All other is combination of C/Tcl modules. It is well suited for what we're doing because of the speed of C and ease of development in Tcl. We considered writing our own app-server way back in 1999 but then AS got open-sourced. This saved us lots of time and trouble. Since then I'm trying to help with the project to give something in return. I would also love to see this project evolves since we're betting our company on it. I also think (we have proved it) that AS can be a very powerful application server. It would be the pitty to neglect this potential. Sure would be a huge problem for us. Same here, our system is based on AOLServer platform and Web gui is only top of the iceberg, the core does all stuf like network/device provisioning, various background tasks. It is all different C/Tcl modules and having them developed under one platform, using same C and Tcl languages is a big susccess. Administration of such system is a breeze, very stable and fast. The only missing part is reentrant expect, for this external expect process should be called. For big complex systems it is natural to extend aolserver from its web-only roots, in many cases it is just extending API, the big modification is driver change, making it more flexible and not HTTP-only will open doors for aolserver to get to application server market. May be having two different versions is a solution, but keeping it as simple webserver and constantly talking how to make it more popular is useless, apache is there already, installation and configuration is much simpler, documentation is complete. Webserver which is more complicated in everything serving Web pages does not have any chances even among developers, i am not talking about people who wants just to try it before starting development. What are AOL's direction and plans for AOLServer? If AOL will say that it wants to keep it as is, just stable webserver, AOL is not interested in extending it, then others who think it should be extended will decide how to proceed. At least it would be fair, i've been hoping that aolserver may be extended for the last 2 years but it never happened, AOL rewrites HTTP driver with every version, squeezing from it another 0.009 miliseconds to serve web pages and making it more and more HTTP specific. AOL web farms are unique, i do not think there will be sites something like it ever, and those sites will not need that kind of performance, but keeping aolserver in this way prevents others to use it more widely and what is more important adding new features. So, what is the answer? -- Vlad Seryakov 571 262-8608 office [EMAIL PROTECTED] http://www.crystalballinc.com/vlad/ -- AOLserver - http://www.aolserver.com/ To Remove yourself from this list, simply send an email to [EMAIL PROTECTED] with the body of SIGNOFF AOLSERVER in the email message.

Re: [AOLSERVER] AOLserver facelift.
Spend some time thinking about it, and when you have a better idea of what that something actually is, tell us all about it. We're all listening. In my case something is: i feel that contributing into AOLServer project feels like asking permission from AOL, is AOL willing to accept or even consider whatever additions i am offering. In most case they will be rejected because of stability, direction, code style or pure messed up code. I understand that AOL pays core developers but i think this is what makes me feel this is not open-source project, this is AOL project with open sources. It is not bad and AOL benefits from this greatly, so many free QA/testers but still, AOLserver goes in the direction at least i do not agree with. I think AOLServer should not be pure webserver, just another webserver even running by AOL, still just another webserver, it has potential to be full-blown application server. I support my patches and develop different version of aolserver, allowing differnet protocols, for example HTTP or SIP over UDP, but i am sure AOL will not accept them, so i keep them to myself. There are many small improvements can be done and i 've done a lot of them, binder for example, many modules. They are public but still, core is what AOL provides. I am not saying the word fork, but it may happen. If you're being intentionally vague about what something is, and something refers to me and my leadership of this project, then please just say so. You are great project leader, no doubt, you just work for AOL, it is very noticable. -- AOLserver - http://www.aolserver.com/ To Remove yourself from this list, simply send an email to [EMAIL PROTECTED] with the body of SIGNOFF AOLSERVER in the email message.

Re: [AOLSERVER] core server design docs
I believe you are talking about the iovec scatter/gather method, which reads/writes from multiple buffers in a single call. It should be much faster for a lot of applications, especially UDP. Likely you have to change one line of code to change nssock into a UDP module (of course it might be nice to do that from a config file setting, which is probably what Vlad did if he has written a SIP server). Change in the nssock driver is minimal, because UDP is much simpler, just one packet, more changes are in the driver itself, i introduced socket type and some buffers. I can publish the patches, they work fine with asterisk and ser and sipura. -- Vlad Seryakov 571 262-8608 office [EMAIL PROTECTED] http://www.crystalballinc.com/vlad/ -- AOLserver - http://www.aolserver.com/ To Remove yourself from this list, simply send an email to [EMAIL PROTECTED] with the body of SIGNOFF AOLSERVER in the email message.

Re: [AOLSERVER] Support for non-HTTP protocols
This is what i 've done with my first version of SMTP driver, i wrote it
in pure Tcl. Performance was terrible, the site was serving
thousands of incoming SMTP connections and it was very slow. Second
version was doing pretty same stuff but in C, i registered TCP callback
and create new thread for each new connection. Not much a difference.
Only after i started using AOLServer's thread pools and
connection manager, performance issues disappear. So if new protocol
does not serve thousands of connections, Tcl/TCP callback
solution works just fine.

Just the other night, I had the need to implement a non-HTTP server in
AOLserver in order to implement the TiVo beacon connection for the
Home Media Option (MHO) feature of the Series2 TiVo. I thought about
both Vlad's and Stephen's approaches, and decided I'd rather stay
pure-Tcl instead. Here's what I came up with:
proc tivo.init {} {
# ...some setting of nsv config vars here...
ns_thread begindetached tivo.beaconThread
}
proc tivo.beaconThread {} {
set address [nsv_get tivo address]
set beaconport [nsv_get tivo beaconport]
ns_log notice TiVo beacon listening on $address:$beaconport
set master [ns_socklisten $address $beaconport]
while {![nsv_get tivo shutdown]} {
foreach {rfd wfd} [ns_sockaccept $master] break
ns_chan create $rfd $rfd
ns_chan create $wfd $wfd
ns_thread begindetached [list tivo.beacon $rfd $wfd]
}
close $master
}
tivo.beacon {rfd wfd} {
ns_chan get $rfd
ns_chan get $wfd
# ... do actual beacon exchange ...
# connection must remain open, so we just poll until the remote
# side disconnects.
while {![nsv_get tivo shutdown]} {
set sel [ns_sockselect -timeout 2 $rfd {} {}]
if {[llength [lindex $sel 0]]} {
read $rfd 1
if {[fblocked $rfd] || [eof $rfd]} {
ns_log notice TiVo: Beacon disconnected.
break
}
}
}
close $rfd
close $wfd
}
The gist of this is that:
1. Can't use [ns_socklistencallback] since our connection handler keeps
the connection open, and that would block the thread that executes
the callback handler.
2. At server start-up, we create a thread to just accept connections
which creates new threads to process those connections.
3. We use [ns_chan] to detach/attach Tcl channels to the socket fd's in
order to pass them from the master thread to the slave threads.
So far, this has been working really well for me. No modification to
the core involved, and it's implemented in very few LOC overall. Using
the same pattern, I could easily implement an SMTP, IMAP, etc., server
in pure Tcl. I'm not sure what the real performance difference there
would be compared to the two proposals that require C code changes in
the core: as long as the actual functionality is implemented in a Tcl
callback that gets invoked from the C code, the performance difference
is probably negligible.
On a side note: if you have a Series2 TiVo with Home Media Option, and
want to serve content to it from AOLserver ... I've got a module that
works (but is far from complete) that does it. :-)

Re: [AOLSERVER] Support for non-HTTP protocols
It is not thread pools by itself but more reusing existing thread pools. If you have AOLServer thread pools and Tcl thread pools and if you have 100 connections always connected to the server and using SMTP and HTTP (this is my case) both AOLServer pools and Tcl pools would compete for the same resources. I do not have Tcl implementation, it was more than 1 year ago and i did not save old experimental code.

Re: [AOLSERVER] Support for non-HTTP protocols
Time and energy have been already spent by implementing/testing those patches, why are we circling around that somebody need to spend efforts to make AOLServer worse HTTP server and better non-HTTP server. Nobody needs to do anything, AOLServer still remains http server, those patches do not even change HTTP processing a bit, they only add additional functionality which co-exists with existing infrastructure making AOLserver more versatile environment. Regarding sendmail list: We use AOLserver with SMTP in front of sendmail and postfix, as MX server, and same aolserver provides us with nice Web interface which simplifies administration to just one server and even that administration goes through Web interface.

Re: [AOLSERVER] AOLSERVER Digest - 10 Aug 2004 to 11 Aug 2004 (#2004-171)
I think everyone would benefit if AOLserver includes some kind
templating solution without installing whole OpenACS system.
Strip down templating with several usefull tags like if include
multirow list and etc would put AOLServer on the same level
as PHP/Perl with Apache systems regarding templating. I can provide
small version of my templating system which is kind of
similar to OpenACS, it can work without any external dependencies. No
documentation but good examples will be a good start.

ns_puts a href=\$link\link/a
Can be written without the quotes simply by doing this:
ns_puts [subst {a href=$linklink/a}];# No escapes required!
True, but subst does still require an amount of escaping in various
situations. For example:
# Lets output some financial data
# We need to escape the $ for the monetary units
ns_puts [subst {
tr
tda ref=link[set $i]Item $i/a/td
td\$$amount($i)/td
/tr
}
# We need to escape the [ and ] for negative amounts
ns_puts [subst {
tr
tda ref=link[set $i]Item $i/a/td
td\$\[$amount($i)\]\$/td
/tr
}
# {} need to be escaped too, if they come up
So, its not as simple as not needing to escape things. There's just less
to escape.
Secondly:
%
if ($condition) {
%
This html
%
} else {
%
This other html
%
}
%
Makes for the most hideous, unreadable and unmaintainable code ever
concieved and should be avoided at all cost if you have any interest in
writing quality code.
For that type of output, yes its not the best choice. However, there are
situations where doing it inside an ns_adp_puts is the more hideous of
the choices. For example:
table
%
foreach row $rows {
foreach {
item1 item2 item3 item4 item5 item6 item7
} $row {break}
### Output a lot of html for each row of data
%
tr
!-- 30 lines of html here that output the items
-- and the form elements involved with them
--
/tr
%
### Done with row
}
%
/table
Tcl is called a procedural language, best to use it that way and create
loads of nice little procedure to create html. Surely,
set table_list [list 1 [link http://aol.com AOL]]
lappend table_list 2 [link http://genie.com Genie]
lappend table_list 3 [link http://msn.com MSN]
ns_puts [create_table -cols 2 -style linktable $table_list]
is a lot more elegant and maintainable than writing all the tags
yourself?
(let alone using ASP style tags)
Very much so, at least for links. Do we actually have a nice, robust
library of procedures that can produce complex html with a simple
syntax? If so, thats great and I'd be happy to hear about it. If not,
then every single person who uses the server to create pages making
their own helper procs is just a source of server bloat.
Even with a good library, there are still some things that are better
written in plain html. Its all about making the resulting page easily
readable and maintainable, in my opinion.

Re: [AOLSERVER] Intermittent hangs without a message
We are running aolserver on Redhat 7.3, 8.0 and Mandrake 10 and never got this problem. RH machines uses older glibc with LinuxThreads and Mandrake uses NPTL.

Re: [AOLSERVER] encoding of ns_sockopen
I have patch that convert aolserver into generic threaded server platform. I had to write SMTP proxy server and it required just a small patch to change default HTTP-aware behaiviour of server thread. Now it supports generic drivers and uses same thread pools/connection driver as for http communications. It is possible to write generic C-module that will register Tcl callbacks and call them at some points and aolserver connection thread will handle the rest. Tom Jackson wrote: Brandy, Thanks for the info. That is very good to know. One thing that is 'busted' in AOLserver is the ability to provide threaded generic servers. I would like to build this in for various reasons, so it looks like the socket/fileevent method might be the way to go, and just forget about threads. For those who don't know, ns_socklistencallback runs in a single thread, no matter how many times you call it with different ip/port combinations. If any client connection blocks, everyone else stacks up waiting. Last week I started working on a shared 'Network Variable' server. Not wanting to write any more C level code, I had to use ns_socklistencallback to receive an ip/port number to dial back to, and start a new thread on the listen server to dial back the client, which had setup a server using ns_socklisten. While this worked great, I ran into another issue: when a connection thread finishes with a connection it forgets about any open fds, so the connection is only available for the first connection. :( So it looks like another project will be to setup a module which allows persistent tcp connections, probably similar to nsdb, but working with arrays instead of ns_sets. tom jackson On Fri, 2004-05-28 at 09:00, Brady Wetherington wrote: Note that tclhttpd uses fileevent to implement a full-fledged single-process select-based web server - I don't know how good it actually is in practice, but it should make for a very high- performance, low-overhead server.

http://sourceforge.net/tracker/index.php?func=detailaid=726288group_id=3152atid=303152
but it is quite old already, i have newer version but did not submit it.
The idea is same just little improvements.
We use this proxy module for 1 year already in th eproduction, no
problems at all, it co-exists with normal http driver
in the same aolserver process, they both reuse same connection pool.
i am working on generic TCP server using new patch, hope to release it soon.
Basically new driver will look like this, just need to export socket
interface to Tcl, so i can read/write
to socket from scripts. All Ns_Conn fields are available and C API i
used same way as for HTTP connections.

That sounds quite useful. Vlad, where is this patch available? Dossy

Re: [AOLSERVER] AOLserver 4.0 Documentation update
Would it be easier to automatically upload existing man pages to Wiki and then go and update them or add new docs? There are a lot of man pages that can be used. Dossy wrote: A quick update -- with the tremendous help of our anonymous prolific wiki updater, the AOLserver 4.0 Documentation effort is underway. The starting point is on the wiki, here: http://panoptic.com/wiki/aolserver/Documentation For the 6/25 milestone, the goal is to have the Tcl API docs complete on the wiki, and the roff format updated in CVS. Here's a link to the Tcl API docs: http://panoptic.com/wiki/aolserver/TclAPI I've only done a four or five commands so far, but it's a start and it should hopefully give a clear idea of the format that I think the documentation should take. Here's a link to an example, for the ns_addrbyhost command: http://panoptic.com/wiki/aolserver/ns_addrbyhost My approach to writing the documentation is to take what we currently have written (in roff format from CVS, from the various documentation efforts that have gone on in the past, etc.), then actually look at the AOLserver source to fill the gaps (undocumented subcommands, behaviors, where the docs and code disagree, etc.) -- this should at least provide us accurate documentation, again.

Having to do it manually forces me to look at each and every man page and go oh god, no, that's wrong and correct it before I move on. It's also an easy way to see progress: docs that are not done yet show up as uncreated wiki links which are visually easy to distinguish from ones that are already created.

Re: [AOLSERVER] ns_logctl expansion?
There is Tcl syslog extension, i use it in my Tcl scripts but it is fo rUnix only. If Windows is one of the platforms syslog may not be portable solution, but if only Unix, collecting nsd.logs over syslog makes life much easier than re-inventing Tcl version of syslog itself.

Re: [AOLSERVER] ns_logctl expansion?

Please note that I'm not *reinventing* anything. I just want to make *existing* ns_log facility be able to use alternative channels apart from the one file-channel hard-wired at the server start. Also, collecting nsd logs over syslog is not much easier. It is, at least in our case, out of the question. The only viable solution for us is to manage our own socket connection to other AS instances and set them to use alternative log sinks. I do believe that this might open interesting possibilities to other AS users, not necessarily familiar with syslog and its configuration.

Re: [AOLSERVER] ns_logctl expansion?
What about making logging facility pool based like db system, define different pools, eventually those logging pools may be not just files but syslog, custom socket etc. Then in your app you just use those log pools, something like ns_log setpool logfile1 ns_log Debug ns_log setpool syslog1 ns_log Debug Just throwing an idea Tom Jackson wrote: On Sun, 2004-03-07 at 23:37, Zoran Vasiljevic wrote: Oh, it is not the work that I'm afraid of :) Your idea seems pretty good.

Or maybe a better idea is to come up with a way of establishing a ierarchy of commands/script files and log based on that criteria instead. If procs were namespaced, a message from a certain namespace could trigger the desired action. Or while loading, library commands could be associated with the files where they were stored...

I'm guessing the motivation is for performance, what if you could register log files like you register Registered Procedures, use the trie structure to store nearest match logging. Then on restart you could easily add/remove a log file for debugging purposes, or long term high performance logging. Oh, misunderstanding... I was talking about the *server* log not the access log. The motivation is not the performance. The motivation is to be able to collect (even over the network) logs produced by many AS instances running all arround the net at one central place. Oh, the stack is thread-wide of course. The ns_log itself is a thread-wide stuff, therefore. We use ns_log facility extensively and need it for various debugging purposes. It proved very clumsy to handle all those logs dispersed on different machines arround the net, so we thought about creating a Tcl channel and sending all the output to one central handling place. Now, one could employ the same principle to access logs as well. The only thing is: I don't know wether there is Tcl access to access logs (I think not). The ns_logctl functionality appearing in 4.0 was a good step towards better server log management. It could be extened even further, as explained in my proposal. The good thing here is: there is no backward-compat to take care of, no users would be affected by this change so there is nothing to fear about. It merely adds new functionality. For some people this may be interesting, for some not. Therefore I wanted to probe wether anybody could benefit from this. We would, definitely.

[AOLSERVER] Initialization crashes in 4.0
i just encountered situation when aolserver crashes on startup, it is rare but...

[AOLSERVER] aolserver 4.0 shutdown hangs
Hello all, i was trying to upgrade to aolserver 4.0 but noticed that every time i do ns_shutdown from nscp the server just hangs.

Re: [AOLSERVER] loading nschartdir
Yes, CharDir library compiled with gcc2.96, so you cannot use it on recent versions of Linux which uses gcc3. I asled them about version for gcc3, but at that time they did not provide it, may now they have more recent version compiled with gcc3. On Redhat you can compile the whole aolserver using gcc2.96.

Re: [AOLSERVER] aolserver4 bad file descriptor errors
But Ns_ConnClose is called from within connection thread and is using mutex for firstClosePtr but at the same time single threaded driver.c is using the same pointer without any mutexes. After i put mutex there i started receiving much less Bad file descriptor errors and crashes which may be unrelated completely but on my fast dual-CPU machine with many concurrent connections that might be the case. Jim Davidson wrote: Hi, I'm not sure this is the case. Code in driver.c is single-threaded by design, i.e., there's a single driver thread which accepts new connections, does the read-ahead, dispatches the sockets with pre-read content to the thread pools for service, receives the sockets back for keep-alive or graceful close. This is why the various lists and counters don't have locks around them. The design assumption is this single thread can spin fast enough to keep a reasonable thread pool filled with incoming requests. For NsSockClose, note there is a lock around the firstClosePtr list which is the list to return sockets to the driver thread. Sockets are put there and a trigger is sent for driver to pull them off. Anyway, that's the plan -- I could have missed something and allowed these lists to be fiddled by other threads by accident. -- AOLserver - http://www.aolserver.com/ To Remove yourself from this list, simply send an email to [EMAIL PROTECTED] with the body of SIGNOFF AOLSERVER in the email message.

Re: [AOLSERVER] aolserver4 bad file descriptor errors
But what about SockAccept and SockRelease, they do not use lock mutex
but update firstClosePtr.
I have small communication driver so those errors may not be related to
firstClosePtr.
Jim Davidson wrote:
Hi,
Seems like firstClosePtr at least is protected -- there's an
informatively named Ns_Mutex defined:
static Ns_Mutex lock; /* Lock around close list and shutdown flag. */
and then in NsSockClose:
void
NsSockClose(Sock *sockPtr, int keep)
{
...
Ns_MutexLock(lock);
if (firstClosePtr == NULL) {
trigger = 1;
}
sockPtr-keep = keep;
sockPtr-nextPtr = firstClosePtr;
firstClosePtr = sockPtr;
Ns_MutexUnlock(lock);
if (trigger) {
SockTrigger();
}
}
and in DriverThread:
static void
DriverThread(void *ignored)
{
...
/*
* Check for shutdown and get the list of any closing or
* keepalive sockets.
*/
Ns_MutexLock(lock);
sockPtr = firstClosePtr;
firstClosePtr = NULL;
stopping = shutdownPending;
Ns_MutexUnlock(lock);
I've debugged a similar problem before -- turned out to be a misbehaved
module closing sockets twice or something. Are you getting these bad
file errors with simple nsd/nssock only configs?

Re: [AOLSERVER] BIG problem with Tcl8.4.(1|2)
Yes, i am currently fighting with the same problem, under big load when i do many calles to Tcl [file] command aolserver crashes consistently in static void FreeFsPathInternalRep(pathObjPtr), but i do not do [cd], just [file mtime,stat,file] When i do not do Tcl [file] command everything is working fine. Zoran Vasiljevic wrote: Hi ! After some days... (yes, it is *always* very costly and difficult) I've pinpointed a large hole in Tcl8.4.(1|2) which effectively generates bogus OS paths, corrupts memory and otherwise impairs the AOLserver (or any other MT-enabled application). The problem is in Tcl generic/tclIOUtil.c and naive handling of static Tcl_Obj *cwdPathPtr. The pointer to this Tcl object gets shuffled arround threads by simple reference, it is read (referenced) without proper locks, etc. The implementor obviously protected the most obvious write operations, but neglected any others. Also, the Rule#1 in Tcl Do not pass Tcl_Obj's between threads is grossly violated. I must see how we can solve this. I'm afraid that we'd need to rewrite some parts of the above file and bump to Tcl8.4.3 or such. How come nobody has noticed this so far? Well, the problem starts displaying itself if you ever change the current directory of the process *after* the Tcl has been initialized. You need not do [cd] explicitly; some internal Tcl code does that on your behalf as well. As for AOLserver 4.0; we do need at least Tcl8.4 or higher. So, I'm afraid we will not be able to go to production before fixing this ugly thing.

negative value whenever the Long IP provided is greater than 2147483647. Can
anyone help figure out why expr will not accept any values bigger than that,
and what my options are? I have looked through the AOLServer functions to see
if there was anything built-in that would work but nothing caught my eye.
Thanks!
proc dotted_ip_from_long { long_ip } {
set n 1
set ip_parts [list]
while { $n 5 } {
set denom [expr int(pow(256,(4 - $n)))]
set ip_part [expr int(floor($long_ip / $denom ))]
set long_ip [expr $long_ip % $denom ]
lappend ip_parts $ip_part
incr n
}
return [join $ip_parts .]
}
