Hi!

Ah, I forgot. The serendipity_options table is only used when the "Remember me" login feature of s9y is enabled.

Without it, no tokens are required for login.

What wonders me about Rinces Dump is that the author_information stuff gets sent when he posts a blog. Usually, this should only happen when "Remember me" is checked. So I wonder why those headers are emitted there, maybe some HTTP POst fields trigger this authentication routine.

However, rinces dump is also missing the POST serendipity_Admin.php authentication. There you should also get an author_token and other cookies!

Maybe someone can look at it before I find the time around Wednesday next week.

What would help:

1. Log out of your s9y blog
2. Remove all cookies that are associated with the URL of your s9y blog. Also truncate your serendipity_options table for all keys that do not start with "t_" in their okey column. Those are template options.
3. Restart your browser, only open your blog URL and no other tabs
4. Open LiveHTTPHeader window. Exclude all permalinks with the pattern .css, .gif, .jpg - so that only PHP actually remains.
5. Go to the admin suite of your blog, directly via serendipity_admin.php
6. After each step you now perform, check the contents of your php session file.
6. Login to your s9y blog
7. Create an entry, save the entry.
8. Save the created HTTP Header dump as well as your tracking of the PHP session file.

For Zugschlus: You might need to repeat those steps until you can reproduce your heisenbug; additionally you might want to simply add more steps of 7.) so that you have more pages to check. Also pay attention to the time you spend on the site; if it reaches your PHP session garbage routine collection, this might be an additional culprit.

Best regards,
Garvin

Is it OK that _eight_ new sess_*-Files appear in /var/lib/php5 when I just call up the blog home page? Which file am I supposed to track?

How can I find out which interval is used for the GC?

Hi!

No, that's not OK. There should be a maximum of 3 session files created with the method I described in the earlier posting.

If you get eight session files, this leaves the conclusion that each HTTP call of yourse might invoke a new session (like a call to CSS stylesheet, javascript files, external plugins etc.).

How can I find out which interval is used for the GC?

Through phpinfo(), check the session.* options and search for "gc".

Ok, that had something to do with the way I coaxed the browser into accessing blog.zugschlus.de in the virtual machine.

I have corrected this, am now doing this via a proxy.pac:

Code: Select all

function FindProxyForURL(url, host) {
  if( isInNet(host, "81.169.156.164", "255.255.255.255")) {
    return "PROXY 192.168.8.132:80";
  } else {
    return "DIRECT";
  }
}

and I only get a single session file now.

session.gc_divisor 100 100
session.gc_maxlifetime 1440 1440
session.gc_probability 0 0

24 Minutes? Or 24 Hours?

Hi,

while I haven't been awfully successful in reproducing the error in my lab setup, the followig perl code might help in keeping a watch on the PHP session directory.

Code: Select all

#!/usr/bin/perl -w

use strict;
use File::Find::Rule;
use File::stat;
use IO::File;
use English;

$OUTPUT_AUTOFLUSH=1;

my $dir="/var/lib/php5";
my %ctimes;

while(1) {
    print ".";
    foreach my $file ( File::Find::Rule->file->in("$dir") ) {
        my $sb = stat($file);
        my $out;
        if( ! defined $ctimes{$file} ) {
            $ctimes{$file}=0;
            $out="new file $file, contents:"
        } else {
            $out="$file changed since $ctimes{$file}, new contents:";
        }
        if( $sb->ctime != $ctimes{$file} ) {
            print "$out\n";
            my $fh=IO::File->new("<$file") or die("error opening $file: $!");
            print <$fh>;
            close $fh;
            print "\n";
            $ctimes{$file}=$sb->ctime;
        }
    }
    foreach my $file( keys %ctimes ) {
        if( ! stat($file) ) {
            print "$file vanished\n";
            delete $ctimes{$file};
        }
    }
    sleep(2);
}

Hi!

What about suhosin? Disabled that already?

IMHO working on this without trying to eradicate suhosin could be unnecessary work, so I'd like you to try to reproduce your heisenbug on an installation without suhosin, before we try anything more.

Garvin

The Debian maintainers of PHP 5.2.5 have assured me that suhosin does - in the default configuration - only add more verbose logs and all "active" things are disabled by default.

garvinhicking wrote: IMHO working on this without trying to eradicate suhosin could be unnecessary work, so I'd like you to try to reproduce your heisenbug on an installation without suhosin, before we try anything more.

Since I wanted to make you happy, I have rebuilt PHP 5.2.5 on Debian stable with suhosin enabled, and all recent tests were done with that PHP version. I was able to reproduce the issue with unpatched 5.2.5 before deleting my browser cookies. Since deleting the cookies, I have not yet been able to reproduce the issue on the test system any more.

I hope that you'll accept header traces from the live system with suhosin after I have tried in the test system and saw the issue there as well, since I am very very reluctant to break the production system where I'd have to exchange the PHP for about a dozen of other PHP apps to satisfy your debugging requirements.

The other PHP applications are usual ones, that do not mangle with PHP session files in a special manor? If any of them might access the session storage path on their own, they could be responsible for interferance?

Squirrelmail is one of the applications that mangle with my PHP session files on my test server...

I am not sure what is installed there since I am not the only user on that box, but I am at least aware of a couple of other s9y installations, gallery, gallery2, pickle, phpmyadmin and dokuwiki.

Hi,

I have found one more specialty of the system in question: All PHP applications running on the box have their own apache instance, all using mod-php, and are running under different UIDs. However, the php instances are all writing their session files to the default directory /var/lib/php5.

I don't know how php builds the session file names, but can this be a source of conflict here? For the time being, I have told the php that runs my blog's php stuff to write its session files somewhere else. I'll report back whether my problem still comes up.

It still comes up, so a potential conflict in php session file names is ruled out as well.

Hi,

finally, I have session data _and_ live headers. Here is what I did:

- delete blog.zugschlus.de cookies
- close firefox
- open firefox
- verify that s9y_option has 0 rows
- verify that blog.zugschlus.de cookies are still gone
- start live headers
- start watchsession
-1- call up blog
-2- call serendipity_admin
-3- log in
-4- click "comments"
=> login screen

This is the output of watchsession; the numbers written right into the watchsession dump show when I did the corresponding thing listed above

The watchsession stuff is cluttered by things generated by other blog users, but I tried using a packet filter to only allow connects from my own client during the test and it was considerably harder to see the issue then.

And here are the live headers:

(Password was changed, all session files deleted before posting this; I hope that I didn't open any holes to the live system by posting this).

Does this output help?

Hi!

Here's your problem:

Code: Select all

Set-Cookie: serendipity[old_session]=f2f84bd24f36d30dd8bc180be7292515; expires=Tue, 22-Apr-2008 08:15:31 GMT; path=/; domain=127.0.0.1:1312

Your server sets a cookie for 127.0.0.1:1312 domain, but your browser rejects this cookie.

I think this is caused by a reverse proxy you are using?

Regards,
Garvin

Thanks for spotting this. Looks like the reverse proxy is acting up as I see the cookie's domain rewritten in earlier requests. I'll do a trace on the circuit between reverse proxy and application.
