Finding folks (was Bug 52633)

In terms of finding people, the place to recruit is the Tcl community at large. On the near-term horizon is the 2012 Google Summer of Code. This won't be a good place to look for the Apache interface, but it's a good place to find someone willing to do relatively simple gruntwork. Something like taking Harald's list of fixes, applying them and testing is a decent summer task for an undergrad. The wiki pages for the 2012 GSoC are http://wiki.tcl.tk/28789 The requirements are that there be an ostensible adult to mentor the student. You don't need to be physically co-located. I mentored a guy from Poland for a couple years. Email, chats or skype are adequate tools. We've assembled some easy-to-swallow Tcl introductions at the Tcl Community Association website to make it (relatively) easy for a student to come to the project unable to spell Tcl and do useful work. http://www.tclcommunityassociation.org I don't know if Rivet has a comprehensive regression test. That might be a good place for a GSoC student. Extending/reworking some of the older code to new standards might also be suitable for an undergrad. One problem we have in the Tcl community with GSoC is too many PhD type projects and too few Sophomore/Junior level projects. The low-hanging fruit in the Tcl Core development was picked in the 20'th century. Happy Tcl'ing, Clif -- ... Clif Flynt ... http://www.cwflynt.com ... c...@cflynt.com ... ..

I'm not sure about defaults, but here's a code snippet using the
TclOO form command. The big caveat on this code is that it works
for the features I needed, but I didn't have time to run it through
complete testing.
form create spForm -method post -name create

Re: namespace command lookup vs lsearch
Hi, Name matches are done through the hash tables, so you get hash speeds. Lsearch is big-O linear. When I last did a lsearch vs hash comparison (for a speed discussion in my book), the difference between lsearch and hash didn't matter until around 500 elements. There are XML parsing libraries for Tcl. I tested them a few years ago, and they all worked. The compiled ones (TclExpat) were the fastest, but not by so much that I cared. For trivial XML parsing, I write my own parser with a simple stack class. I've never seen the need for a tree in any XML pages I've seen. Hope this helps, Clif -- ...

Web Tech panel at Tcl-2011 US
Hi, I'd like to assemble a compare and contrast panel at the Tcl Conference to discuss tclhttpd, Rivet, AOLServer and Wub. Would anyone from the list be attending and willing to be the advocate for Rivet? My plan is for me to to be moderator. I've used all of these packages, but am expert at none. Here's the proposed question list for the panelists. Other suggestions are gleefully accepted. Please let me know if anyone can do this. If we can assemble the experts, I'll get it onto the schedule. Thanks, Clif What distinguishes your package from other tcl http engines? What's the best reason for using your package? What's your packages weakest feature?

Speaking of Tcl-US 2011
It seems to me that there's more web activity now than there's been in several years. This might just be because I've got a contract doing some web-work for a change, but... In the Tcl arena, we've got: tclhttpd - old, reliable, stable and obsolete (but I use it). wub - new, snazzy, up-to-date and fluid (I use this one, too). rivet - stable, integrated with the most-used server (yeah, I use this one). ?others? - I probably missed a dozen or two that I don't use. Would it be reasonable to do a compare-and-contrast panel at the Tcl conference? Would anyone be willing to step up and defend their turf? FWIW: I use tclhttpd when I've got a fairly simple task that doesn't need anything fancy. I used tclhttpd to set up sample exams for my students when I taught Tcl at EMU - a separate tclhttpd (and port) for each exam, was trivial. I use wub for the Tcl Community Association pages mostly because the pages are co-hosted with the wiki.tcl.tk, and that's wub. It's nice in that it supports lots of new stuff. Less nice because it changes and grows. I'm using rivet for a commercial task because Apache is solid and nobody questions using it. Rivet isn't moribund like Tclhttpd, but it's not so fluid that I worry about my code breaking with the next release. Happy Tcl'ing, Clif -- ...

Persistent DB connection
Hi, I think I'm missing something simple. I may be getting bit by threads. The system I'm building is a database backed web application. Nothing particularly complex. I open a connection to the database using tdbc - this creates a new command that I put in the global scope as '::db1'. A few minutes later, I hit a web page, and the command is gone. It's simple enough to re-create it, but I'm getting bored with adding the 'is it still here' check to my code. Is there a way to open a persistent link? Or am I getting caught by a new thread being assigned to a session and the new thread has never heard of any ::db1 command. Maybe I should drop the tdbc idea and move to dio... My primary reason for using tdbc is that I'm not convinced that we won't be switching backends before we get out of prototype mode and tdbc seemed like the simplest way to be server-neutral.

The reason you're hitting this is because every time you request a page, you get a random child process from Apache. You don't know which one you're going to get, and it's unlikely you'll get the same one over and over again. Once you create the DB handle the first time in the global scope, it will remain in that Apache child, but you may get a different child next time. Thanks. I was suspecting something like this. Eventually, all of the children will have a ::db1 procedure, and all will be happy. I was afraid that I was causing some unnecessary thrashing, but I guess it's necessary after all.

form.tcl -method get|post?
Hi, I'm using rivet 2.0.1. The form package docco says: -method ?post|get? The http method for sending the form data back to the server. Possible values are get or post Note At the time of writing only the 'get' method is implemented My test indicates that putting -method post results in a 'get' operation. Is this likely to be updated/modified? Is there a variant of form.tcl (cvs tip?) that supports post? I grabbed the CVS tip of Tcl8.6 (yeah, living on the edge) in order to get the newest tdbc. For reasons unobvious to me, the itcl that builds out of the box doesn't quite support pure itcl syntax. In particular, it requires a [self] methodName to invoke internal object methods from within a method. I've got a kludged version of form.tcl that works (to the extent that I've tested it) with the new 8.6. Is anyone interested in this code? I'm not sure that my kludge has long term use, though it might provide a start on a port from itcl to TclOO. Thanks, Clif -- ... Clif Flynt ... http://www.cwflynt.com ... c...@cflynt.com ... ..

yes, I am.
I've attached it to this email. If attachments get scrubbed, let

It's something we should talk about. Tcl 8.6 is getting momentum among the
Tcl'ers and its new introductions will probably set new standards in the
language history.
I'm pretty bullish on TclOO. I think it's a nice mix of providing
structure while still giving the developer the freedom to rework
things as his understanding of the problem matures. (How's that for
buzz-word compliance?)
I worked in C++ for 5 or 6 years and did a little with itcl. I ended
up unthrilled with OO. TclOO has revived my excitement.
This construct in the form.tcl code was the only one that caused
me some dismay at a quick-N-dirty translation to TclOO:
public variable defaults {
upvar 1 $defaults array
array set DefaultValues [array get array]
}
I think this can be implemented in TclOO with a variable trace and a
new object method, but I didn't have time right then to play with it.

Hi, I'm starting a fairly major project and intending to use Apache2, Rivet and the 8.6 tdbc and TclOO. We're anticipating 1000+ simultaneous users once the system goes live. I'll be beating on the form.tcl package fairly hard (already had one go-to with it). I've got a version of form.tcl that's happy (partly) with the 8.6 out-of-the-box version of Itcl. This seemed to want a few more of the TclOO constructs (using [self] to call object internal methods.) Suggestions and comments are welcome. Clif -- ...
