It seems official downloads are supposed to be at http://qa.php.net/, but for some reason, that site isn't loading for me. Is there an alternate location to download 5.6 from? ------------------------------------------------------------------------ [2014-07-13 09:53:26] yohgaki@php.net Sorry for typo. Could you try 5.6? ------------------------------------------------------------------------ [2014-07-13 04:55:41] nachms+php at gmail dot com I just tested with 5.5.12, getting the same results as I did with 5.3.x and 5.4.x, so yes, the bug has not been fixed. I noticed my pastes with test code expired. So I quickly whipped up some more: HTTP: http://paste.nachsoftware.com/Nach/LnpHS6e57f952e3f56df4fcc753c210e8401a7vM CGI: http://paste.nachsoftware.com/Nach/vCDhzd84835a1b4439c96ad0353c2111051a09zj ------------------------------------------------------------------------ [2014-07-13 01:08:36] yohgaki@php.net PHP 5.5 and up should be able to handle large input. Do you still have this issue? ------------------------------------------------------------------------ [2013-02-20 03:47:08] nachms+php at gmail dot com Hi payden, Thanks for the info and your test script. I'll try to run some tests myself when I get a chance. No worries about hardcoded data, you'll see the C files I provided hardcode data as well. Regarding the comment breaking, did you test to ensure things are not broken with the original un-commented PHP code? Also, the PHP I provided actually contains a typo, fclose($tfp); should be fclose($ifp); Perhaps this is why things are being left open? As for the 4GB limitation, indeed 99% of users would not care. However I created a file-sharing website using PHP, and ran into this ridiculous limitation. For the time being, I'm using a slight variation on my patch here on my Apache+FastCGI+PHP5-CGI site. I have yet to play with the PHP5-FPM SAPI though, but hope to thanks to your script. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
