WebSockets Handshake non HTTP conforming?

nospam@example.com (Mike) — 2010-05-10T10:16:00Z

Update:

Just found a revelatory discussion. The summary of Bjoern Hoehrmann is especially interesting with regards to that topic.

While skimming through the new HTML5 WebSocket draft, I noticed the following exemplar HTTP message demonstrating the client message of a WebSocket handshake:


        GET /demo HTTP/1.1
        Host: example.com
        Connection: Upgrade
        Sec-WebSocket-Key2: 12998 5 Y3 1  .P00
        Sec-WebSocket-Protocol: sample
        Upgrade: WebSocket
        Sec-WebSocket-Key1: 4 @1  46546xW%0l 1 5
        Origin: http://example.com

        ^n:ds[4U

To me this looks non conforming to the HTTP spec due to the lack of an indicator that the request contains a message body.

Quoting the 4th paragraph of section 4.3 of RFC2616:

The presence of a message-body in a request is signaled by the inclusion of a Content-Length or Transfer-Encoding header field in the request's message-headers. A message-body MUST NOT be included in a request if the specification of the request method (section 5.1.1) does not allow sending an entity-body in requests. A server SHOULD read and forward a message-body on any request; if the request method does not include defined semantics for an entity-body, then the message-body SHOULD be ignored when handling the request.

Huh?

PHP commandline highlighter

nospam@example.com (Mike) — 2009-04-10T12:29:16Z

Just chewed up a command line highlighter for php code.
It's hacky, but it fullfills my needs.

pecl_http and sub-second timeouts

nospam@example.com (Mike) — 2008-12-05T13:13:00Z

Just a quick info, because I forget this again and again--and it's not noted in the documentation yet either.

Sub-second timeouts are supported by libcurl and thus by pecl_http--yes but only if libcurl is built with (c-)ares support:

If libcurl is built to use the standard system name resolver, that portion of the transfer will still use full-second resolution for timeouts with a minimum timeout allowed of one second.

I tried to post a comment at the regex chanllenge on ubuntu-tutorials.com

nospam@example.com (Mike) — 2008-11-19T14:30:22Z

...but somehow managed to not get through, so here's my attempt:


awk -v RS="[\n ,]+" '{print}' < u.txt

Vpopmail and people reaching their maildir quota

nospam@example.com (Mike) — 2008-11-18T13:25:25Z

This tiny program lists all users of a domain with a maildir quota usage above 90%.


#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <string.h>

#include <pwd.h>
#include <errno.h>

#include <vpopmail.h>
#include <vauth.h>

int main(int argc, char **argv) {
    struct vqpasswd *user;
    char dir[1024];
    uid_t uid;
    gid_t gid;
    int offset_counter = -1, sort = 1, usage;

    if (argc != 2) {
        fprintf(stderr, "Usage: %s <domain>\n", argv[0]);
        return EXIT_FAILURE;
    }
    if (vget_assign(argv[1], NULL, 0, &uid, &gid) == NULL) {
        fprintf(stderr, "domain '%s' does not exist\n", argv[1]);
        return EXIT_FAILURE;
    }
    if (setgid(gid) || setuid(uid)) {
        fprintf(stderr, "could not setuid/setgid to %d:%d\n", uid, gid);
        return EXIT_FAILURE;
    }

    while (NULL != (user = vauth_getall(argv[1], !++offset_counter, sort))) {
        if (strcmp(user->pw_shell, "NOQUOTA")) {
            snprintf(dir, sizeof(dir), "%s/Maildir", user->pw_dir);
            usage = vmaildir_readquota(dir, 
                format_maildirquota(user->pw_shell));

            if (usage >= 90) {
                printf("%s %s %d\n", user->pw_name, user->pw_shell, usage);
            }
        }
    }

    return EXIT_SUCCESS;
}

Qmail + SpamAssassin + selectivity

nospam@example.com (Mike) — 2008-11-18T13:18:44Z

Here's how my qmail-queue script looks like to selectively check messages with SpamAssassin for non-relay clients only:


#!/bin/sh
(if [ -n "${RELAYCLIENT+1}" -o `id -u` != 64011 ]; \
    then cat -; \
    else /usr/bin/spamc -x -U /var/run/spamd/spamd.sock; \
fi) | /usr/sbin/qmail-queue.orig

For the records.

Introducing libcurls multi socket API

nospam@example.com (Mike) — 2007-09-11T17:09:00Z

So, finally a first beta of pecl_http 1.6 has been released.

This is the first version which supports libcurls multi socket API introduced in 7.16 through libevent.

Here's a not very impressive comparison of the performance of the traditional multi API vs. the new multi socket API:

So, apparently time savings are not huge, but noticable.

Definitely

nospam@example.com (Mike) — 2007-05-31T18:25:00Z

Well, it's this time in one's life, you know...

I'm single again, and I'm looking for a radical change in my life.

I'm going to abandon being self-employed and looking for a PHP/HTTP/CURL related job.

Some info about me, even in german.

Silence

nospam@example.com (Mike) — 2007-05-23T17:14:00Z

It's been more than 3 months that I brought back to mind, what was happening in my PHP/HTTP/CURL world, so here we go.

February:

pecl/http with support for persistent handles has been released.

A proposal of mine at internals to change the behaviour of read_property/write_property and get_property_ptr_ptr object handlers has successfully been ignored.

The idea was the following:

Wouldn't it be reasonable for the engine to use get_property_ptr_ptr() whenever it wants to modify a property and get rid of using read_property() for write access?

That would make rather simple ops like concatenation, in-/decrementation etc work again with overloaded internal classes. Just make the engine use read_property() followed by a write_property() when there's no get_property_ptr_ptr().

Nobody was interested.

March:

I added a comparison object handler to the DateTime class, which means that comparisons of DateTime objects should work in recent PHP5 versions.

I started development of pecl/libetpan, but dropped it again because of pretty huge differences between how the library works and how PHP is supposed to work. What a pity.

A less fine guy, some Omid, wanted me to write a PHP extension which calculates the strength of "poker hands", but he jumped off when I had done the algos.

April:

A fine guy, pretending his name was Andreas Weber, noticed that pecl/http's request method implementation was completely b0rked. Thanks to his report it was fixed in 1.5.3.

All fame Lukas Smith, queried me about what might have changed with my new output layer implementation for PHP6, but I noticed too late that it's been for a conference talk he was preparing, so I feel like I didn't spend enough attention to his questions. Sorry Lukas.

I started to implement libcurl's new multi_socket AKA hiper API in conjunction with libevent, but stumbled across a few problems.

May:

My journey with libcurl's multi_socket API continues, which eventually causes the delay of a first pecl/http 1.6 release candidate.

I tried Drupal for the first time.

Well, that'd be it. If it reads like an extrusion of junk, it probably was.

nuff!

nospam@example.com (Mike) — 2007-05-22T10:42:00Z

I cancelled my German PHP-Magazine subscription last fall. I even got a cancellation confirmation letter on behalf of them on 10/10/2006.

The funny journey began shortly after. I got each 2007 issue twice, last month an issue of the dot-net magazine and now again the 04.07 issue of the PHP magazine. The subscription was supposed to end with issue 03.07.

I already wrote mails to abo-at-phpmagazin.de and info-at-software-support.biz, without response.

Now I'm sitting here--quite puzzled--with issue 04.07 and am looking forward to my 2007 subscription invoice... hm... now I wonder if it will be for the dot-net or the PHP magazine :-/

New development page

nospam@example.com (Mike) — 2007-05-19T19:45:00Z

I've finally created the basement for a development homepage, where I'll be hosting all my projects.

Drupal serves as the CMS, and I'm pondering moving my s9y--which sucks--blog over to this site. It seems that there'd be everything I needed.

Let's see if I get the menu for the blog right...

Wishlist

nospam@example.com (Mike) — 2007-05-09T19:25:00Z

Yes, this gonna be my wishlist placeholder.

Thank you.

Phar vs World

nospam@example.com (Mike) — 2007-05-09T10:30:00Z

Recent discussions about inclusion of pecl/phar into the core distribution shows again that we are missing a defined process of handling additions to the PHP main distibution. How many people are really reading through all mails of 100+ message threads?

It's going to be a chaos. Always. Once a developer has got his new, shiny and soon-to-be-world-dominating extension into the core, he'll be a even stronger advocator of the "no-new-extensions" camp. Not to disrespect any work, but this is pure rivalism, masculine--really!

The idea of moving extensions from core to pecl is honorous, but we all know the current problems of this ideology.

Many people have asked me when pecl/http will be included in the main distribution. My answer is short and simple: "Never" (I usually add a tiny sentence, but that's nothing encouraging either).

Ah... and please do me a favour: rather keep your comments to yourself (...or toss it into the nonsense thread@internals).

Two pitfalls in one afternoon
