Re: http server hangs on post without enctype=multipart/form-data
I was thinking about rewriting the server, I already wrote a prototype asynchronous http server but I have only the reading part non-blocking and not the writing part yet. I do not want to spend too much time on it right now. Sorry, I was not clear. It would not have to be a asynhronous server, just structured a bit differently than the current one... but then how far do we want to go changing the server? We would need to be careful to keep it working with @lib/form.l Cheers, Tomas -- UNSUBSCRIBE: mailto:[EMAIL PROTECTED]
Re: http server hangs on post without enctype=multipart/form-data
An even better solution might be to extend the built-in 'line' function in that a way that when only a single 'cnt' argument is passed it is taken as a length parameter. The idea is that in the current semantics of 'line' a single 'cnt' argument makes no sense. But would cnt mean number of chars or number of bytes? That could be confusing.

Reference links in generators
I just realized I haven't had the need to do a reference link lookup until know and don't really know how. Pretend we have +User(s), they are from different countries like so: (rel country (+Ref +Link) NIL (+Country)) Now if I want to have all the Germans, how would that generator look? Maybe like this?: (country +User (db nm +Country @CountryName)) Or is there an easier way? I'm looking at this example: http://www.mail-archive.com/picolisp@software-lab.de/msg00567.html But I don't really understand what is happening there since I don't know what is hiding behind all the symbols, what is the meaning of this line for instance: (nm +Ort @Ort (ort @Cls)) that last (ort @Cls)?

OK, I've built this now. The 'ht' library has a new function 'Read'. I had also to change lib/form.js (remove the linefeeds from the data sent by a XMLHttpRequest). It is available in the new picoLisp.tgz. I hope this is all right. Needs good testing ;-) @Henrik: Now it should be OK if you remove your patch from jQuery.

Re: http server hangs on post without enctype=multipart/form-data
Hi Tomas, you to get http query vars in assoc list (see *HtVars and *HtVarsHook). Sometimes it is possible to make application-specific changes or extensions dynamically at application startup, without the need to modify the system files. For example, your extension of '_htSet' (de _htSet (Var Val) (if (and *HtVarsHook (*HtVarsHook)) (push '*HtVars (cons (pack Var) Val)) (use (@N @V @Z) ... can also be be achieved with (redef _htSet @ (if (and *HtVarsHook (*HtVarsHook)) (push '*HtVars (cons (pack (next)) (next))) (pass _htSet) ) ) Cheers, - Alex -- UNSUBSCRIBE: mailto:[EMAIL PROTECTED]

Hi Alex, (redef _htSet @ (if (and *HtVarsHook (*HtVarsHook)) (push '*HtVars (cons (pack (next)) (next))) (pass _htSet) ) ) thank you, I will use this;-) Tomas -- UNSUBSCRIBE: mailto:[EMAIL PROTECTED]

Re: http server hangs on post without enctype=multipart/form-data
Hi Tomas, I would expect 'char' to block and return next character when available and 'peek' return the next character if available otherwise return nothing without blocking. On that level there is no concept of blocking. Data are read as a logical stream. Something similar to what you suggest might be achieved with 'poll', but not completely, and probably not in our case. 'peek' returning nothing would have a different meaning. For normal operations I *do* it want to block, until I receive all data. I guess it seems broken to me because of the two char lookahead in 'char', but is it necessary? Is it only to handle different line endings? 'char' has to cooperate with 'read', 'line', 'till', 'skip, etc. And the logic behind these functions (most notably 'read') require that internally there is always a single-character lookahead, and thus one more character read than necessary.
