Bug #65453 [Fbk]: Readfile() + mpg = http status 500, windows server 2008 r2 sp1, php 5.5.1

Edit report at https://bugs.php.net/bug.php?id=65453&edit=1 ID: 65453 Updated by: ab@php.net Reported by: oli dot laurel at arcor dot de Summary: Readfile() + mpg = http status 500, windows server 2008 r2 sp1, php 5.5.1 Status: Feedback Type: Bug Package: IIS related Operating System: Windows Server 2008 R2 SP1 PHP Version: 5.5.1 Block user comment: N Private report: N New Comment: CLI server also shows 200. It'd make sense to ask on IIS forums as well, as nothing points to PHP yet. Previous Comments: ------------------------------------------------------------------------ [2013-08-20 12:34:12] ab@php.net I've just tried this with a text file of 6M with no reproduce. Please post the output of these commands wget --server-response --limit-rate=40000 http://127.0.0.1/65453/index.php You can also try curl. It's available for windows or with msysgit shell curl -v --limit-rate 40000 -o /dev/null http://127.0.0.1/65453/index.php Thanks ------------------------------------------------------------------------ [2013-08-16 07:45:46] oli dot laurel at arcor dot de hi, thank you for reply. - does the same happen when you out a plain text file instead of mpeg, also using appropriate content-type and --limit-rate? i changed content-type to text/plain and renamed movie.mpg to movie.txt. No behaviour change. If i abort download i will also get a 500. - does it happen when you request static content using wget with --limit-rate? no, if i just download a file for example http://127.0.0.1/movie.mpg all works fine. Also if i abort download.

In the BT there is nothing about PHP. Combined with the fact you find nothing in the error log, it might be not PHP. How did you get that BT? Debug symbols should be used for PHP as well. And when IIS starts, you should attach the debugger to the clean PHP fcgi process, so then debugger takes over. Some more points before i go try it - does the same happen when you out a plain text file instead of mpeg, also using appropriate content- type and --limit-rate? - does it happen when you request static content using wget with --limit-rate? - please post the request/response headers Thanks. ------------------------------------------------------------------------ [2013-08-15 07:41:11] oli dot laurel at arcor dot de Description: ------------ - Installed a blank Windows Server 2008 R2 SP1 Standard, added Role IIS & Feature CGI. - Extracted 5.5.1 VC11 x86 Non Thread Safe to c:\Program Files (x86)\php - Installed vcredist_x86.exe - Configuration of IIS: added Handler Mappings in IIS Request path: *.php Module: FastCgiModule Executable: c:\Program Files (x86)\php\php-cgi.exe Name: PHP via FastCgi - Then added 2 files to C:\inetpub\wwwroot index.php & movie.mpg (6MB) - Installed wget. - No modification of php.ini, no malware scanner, ...
