Hello,

I know this isn't as exciting as the GOTO discussion, but I need some help.
I don't know if this just my fault, or if it's a PHP problem.

Consider this:
<?

$fp=fopen('compress.bzip2://http://php.net/backend/notes/all.bz2', 'r');

while (!feof($fp)) {
   echo fgets($fp, 4096);
}

fclose($fp);
?>


This gives an error:
Warning: `fopen()` 1137 bytes of buffered data lost during stream conversion!
in /cvs/livedocs/test_bz.php on line 3

And outputs nothing more. I'm using PHP 5.1.

Whats is wrong here?


Thanks for your time,
Nuno

I just wanted to be sure I wasn't making any newbie mistake :)

Most likely a bug in the bzip2 wrapper.
It might not be fixable, and it might be better to use Sara's bzip2
filter from pecl instead.

This code is in PHP 5.1. We have plents of time to fix it.
If the PECL code works, why not copy it? I need this to allow anyone to
compile livedocs with notes (without needing the token)

A filter != wrapper, so copying the code won't work.
Filters are preferred over wrappers for compression/decompression in any case.

I didn't say we weren't going to fix the bug, just that it might not
be fixable; need to check into it.

You don't *need* it, since you can always do this:

$name = tempnam('/tmp', 'notes');
copy("http://.....", $name);
fopen("compress.bzip://$name", 'r');

The point of the token is that people can not get the notes easily. So I
wonder how you're handling this now...

They are in all mirrors at: http://php.net/backend/notes/all.bz2

Great idea, Wez!

It is working now.
