conference thoughts
by Bill Welliver 30 May '04

30 May '04

I was discussing the topic of the next Pike conference with Martin Baehr earlier, and we thought that it might be good to share our thoughts and get a discussion going. Basically, the conversation centered around 2 points: where to have it, and when to have it. On the first point of location, Martin has done some initial legwork. He's located a few potential locations, at least one of which has real potential in my mind. I'll let him talk about them if he feels it appropriate. The subject of when to have the conference is a little bit more important to me, as I'm starting a new job and need to know when I'm going to be away from work. Ideally, I'd like to be able to attend, and for that to happen, a date range somewhere between the middle of September to the beginning of October would be ideal. I say ideal because it gives us about a year since the previous conference, it's not in a peak vacation period for many people with jobs, and the weather hasn't turned unpleasant for those with travel/holiday plans incorporating the conference. For those who aren't keeping track, last year's conference ran roughly between the 24th and 28th of September in Paderborn, Germany. Any thoughts? Bill

But I imagine roughly the same amount of hassle and expense occurs if the conference is in Germany, so I didn't mention that. :-) > Besides, if we're getting picky about location, wasn't the conference > the year before at Roxen HQ? (Not that I'm trying to be difficult or > anything) Actually, no. There were no Pike conferences at all before the one at Linköping University in 2002. There were brief visits at Roxen HQ during the Roxen User Conferences earlier years, but the conferences were not held at Roxen HQ, but rather in a specially rented movie theatre nearby. > One thing might be to consider locations where there are known pockets > of Pike developers that we might want to engage.

Also, several of the countries east of Germany (including Poland, Estonia, Latvia, and Lithuania) joined the European Union earlier this month, after years of negotiations, so it has just become easier both for the people there to travel elsewhere in the EU, and for us to get to them. / Leif Stensson, Lysator Previous text: >2004-05-29 04:27: >Subject: Re: conference thoughts >-------------------------------------------------------------------- >Sounds like a good task for a group of his new pike students :) > >> Another possibility might be Dresden.

Events in pike?
by Marcus Agehall (Scanian) ＠ Pike (-) developers forum 29 May '04

29 May '04

Is there anyone except for me that likes to use events in their code? In several of my projects, I've implemented eventsystems with a register_event() method and a fire_event() method in a very simple fashion. The thought has occured to me, to write something more general and put it within Pike. But before I spend any time on it, I'd like some input on the matter. For instance, is it useful enough to write put in Pike? Would you like it to work in some special way? How do you normally implement events in Pike?

Using Pike 7.5.17 compiled by Peter Bortas, I got the following error: \home\peter\hack\Pike\7.5\src\threads.c:65: Fatal error: \home\peter\hack\Pike\7.5\src\threads.c:182: WaitForSingleObject((*(&c->lock)), 0xFFFFFFFF) == ((((DWORD )0x00000000L) ) + 0 ) Unexpected error from thread function: 6 Backtrace at time of fatal: Is that a known bug? My code starts a lot of threads (about 20 simultaniously running) which scans directories for their permissions.

Quoting in Standards.URI
by Martin Stjernholm, Roxen IS ＠ Pike developers forum 26 May '04

26 May '04

Seems like Standards.URI do neither encoding nor decoding according to rfc 2396: Pike v7.7 release 3 running Hilfe v3.5 (Incremental Pike Frontend) > object uri = Standards.URI("http://foo/a%3Fb?c"); > uri->path; (1) Result: "/a%3Fb" > _Roxen.http_decode_string (uri->path); (2) Result: "/a?b" > uri->path = _; (3) Result: "/a?b" > (string) uri; (4) Result: "http://foo/a?b?c" Is it per design? I think it's pretty clear that it should handle this detail too. Unfortunately it's quite a problem to change that now since this class already is used extensively, and changes in quoting behavior is one of the most notorious compatibility problem generators. Someone got any idea about how common it is that calling code "works around" this by doing its own encoding and decoding?

Python's urlparse module also doesn't unescape: http://docs.python.org/lib/module-urlparse.html

Quoting in Standards.URI

Another one might be Subverson URL:s, if support for filenames containing "/" is ever added (could be used on old MacOS). There didn't seem to be much incentive for doing this last time I checked though. :-)

Process.create_process in 7.6
by Bill Welliver 25 May '04

25 May '04

It appears that one can no longer pass a Stdio.Port() object as stdin to Process.create_process. We had been using this method to process FastCGI, but now with 7.6, it seems that passing a Stdio.Port in options->stdin throws an error. Does anyone know if this was an intentional change or whether there's a workaround? Bill
