Summary0011362: Picture dowload fails wit exhausted memory error with firefox 3.5.7 but not with IE8
Description

When I try to download a small picture (PNG or JPG) that was previously successfully uploaded and is displayed properly as preview, I get a page with a lot of strange characters. At the end the following error message:

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 524289 bytes) in D:\Programs\xampp\htdocs\Mantis_Ontw\file_download.php on line 191

This only happen with the latest firefox 3.5.7 browser. I don't recall this happening before so I am not entirely sure that the error is in Mantis and has nothing to do with firefox. It does not happen with IE8!

I took the file_download.php from the nightly built. On firefox, the preview disapeared and the download still gave an error. This time it was just the error:
( ! ) Fatal error: Call to undefined function http_content_disposition_header() in D:\Programs\xampp\htdocs\Mantis_Ontw\file_download.php on line 121
Call Stack

Time Memory Function Location

1 0.0018 130408 {main}( ) ..\file_download.php:0

I will try to create a full mantis installation with the nightly built this week.

Also experienced issue with Firefox 3.5.7 on Karmic MantisBT v1.2RC2 but not anymore on MantisBT 1.2.0rc2 git live as of 20100122

Lots of changes in the respons in the Content-Disposition area.
WRONG
Content-Encoding: gzip
Keep-Alive: timeout=2, max=100
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: text/html

OK
Content-Disposition: filename="Error.png"
Content-Length: 12553
Connection: close
Content-Type: image/png

and possible more.

Since the download is ok (despite of the error) but the error message is appended,
I was forced to suppress error by "@" in the file_download.php:
@$buffer = file_get_contents.....
Otherwise it breaks or distorts various text files - xml, txt, etc.

Hope this will be fixed somewhen.

Can you please use a clean checkout of the latest 1.2.x master or 1.3.x master branches? Overwriting individual files in your old installation with newer files from the git repository won't work. It's an upgrade all or nothing problem :)

With a clean checkout (please specify if you're using 1.2.x or 1.3.x or both), do you still get the memory exhaustion error message appended to the end of the HTTP response?

I met the problem like this in mantisbt-1.2.0rc2-2010-02-19-master-1.2.x-4a56720.when i view have two small images,the page view.php?id=bugid can't display,i can only see the error message like "Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 524289 bytes)".
but it's hard to reproduce,i only met one time.

I have this problem too.

I use Mantis 1.2.0 Final and Firefox 3.6 in Windows XP SP3.

IE8 does not show this problem:

Error occurs when i change from view.php (with inline jpg) to view_all_bug_page.php.

I have this problem too. Mantis 1.2.0 Final and Firefox 3.6 in Windows XP SP3.
Problem is also with downloading file (errors, problem with opening files ) not only with memory.

Allowed memory [...] in [...]/file_download.php on line 209

Issue has attached 3 pictures:
72,892 bytes
67,737 bytes
91,242 bytes

memory_limit = 512M in php.ini

SOLUTION from previous version:
file_download.php (line 159)
change file_send_chunk( $t_local_disk_file ) to readfile ( $t_local_disk_file )

I couldn't reproduce the problem before but this issue seems to keep reappearing. As PHP's readfile() does it's own chunking we don't need a custom implementation of our own. Hopefully this solves all the reports we've been having of file downloads not working nicely with large files.

Please let me know how this fix works out for you.

Works for me too, I applied the first diff to the 1.2.0 installation I have here, it now works just fine.

Note: I have no idea what the second diff is for, it seems it does not apply to the 1.2.0 release
