Hi,

When this option is enable: Asynchronous Operation: output HTML, close connection, then store static file.
I get this error for any visited cache page:

Type php
Date XXX, XXX, XXX - XXX
User Anonymous
Location http://www.XXX.XXX/XXX/XXX
Referrer
Message Cannot modify header information - headers already sent in /var/www/vhosts/XXX.XXX/httpdocs/sites/all/modules/boost/boost.module on line 4097.
Severity error
Hostname XX.XXX.XX.XXX
Operations

This option worked fine before I done a clean upgrade from 1.03 to 1.17

Thanks

What module are you using that could set a header & not be using drupal_set_header()? In any case to prevent this error from ever happening we can use headers_sent() to check before calling boost_async_opp().

this will move the call into hook_exit; hopefully it will give us the correct location of where the headers are being sent from.

committed; turn boost verbose setting up to 7 and let me know what the output of the dblog is.

I apply the new patch and change vebose setting to 7, here is the results:

1. "Message Headers already sent in on line 0. Asynchronous Operation will be disabled." Is now not showing when disabled
2. "Message Headers already sent in on line 0. Asynchronous Operation will be disabled." display when enabled (in vebose up tp 7 or 5 {I checked only these two settings})

here is the other notices that was appear after changing the vebose from 5 to 7 (display before and after the patch):
1.

I will not be available until the weekend, so I will not be able to test new patches.
Thanks for your help.

I need a list of all your enabled modules; one of them is conflicting with the way boost's async operation is working & I would like to know what could be causing the issue.

Hi, I am also seeing this bug in a format that's easily replicatable. The issue is with pathauto. I'm trying to make a large number of aliases. When I run this script, I get the following error:

php pathauto.php

Warning: parse_url(http:///.): Unable to parse URL in /var/www/autism.healingthresholds.com/sites/all/modules/boost/boost.module on line 2760

Disabling boost fixes the error.

makes since
http://us.php.net/parse_url

On seriously malformed URLs, parse_url() may return FALSE and emit a E_WARNING. Otherwise an associative array is returned...

Wrap parse_url in a try catch block; change the logic so it will fail gracefully?

Is this in the latest dev release? If so, I can download and confirm the fix for you?

Hi dankohn,

I'm sure it is in the latest dev release indeed.

From the CVS list:

#657960: catch errors thrown by parse_url().

Without any offence: #657960 refer to this post node id. :D

[Warning: Cannot modify header information - headers already sent by (output started... ]

These problems will face the situation causing the error as follows:
- If you use Unicode UTF-8 editor, you check to see strange characters will appear the file. Check with the editor like notepad, notepad + +.
- Add the following function in the first line of code:
ob_start ();
