#42280 [Opn->Bgs]: Change in file upload behavior

ID: 42280 User updated by: chris at dented-planet dot net Reported By: chris at dented-planet dot net -Status: Open +Status: Bogus Bug Type: *General Issues Operating System: Mac OS X 10.4.10 PHP Version: 5.2.4RC1 New Comment: There is no bug here. Only someone who doesn't completely understand how to compile source code. I was reusing the same source download over and over switching between --enable-debug and --disable-debug. While I rm'd config.cache, I didn't remove other generated files in the source directory. I assumed they'd be overwritten. Once I downloaded a virgin source code for 5.2.3, the "bug" no longer occurred. Sorry! That being said, can you suggest a good book on learning and compiling C? I think it's about time I learn a bit more so this doesn't happen again. Previous Comments: ------------------------------------------------------------------------ [2007-08-12 22:45:49] chris at dented-planet dot net I compiled each version myself from source downloaded from php.net I used the --disable-debug config setting and phpinfo() says "Debug Build No" ------------------------------------------------------------------------ [2007-08-12 22:16:38] jani@php.net Are you absolutely sure you do NOT have a debug build? (check from phpinfo() output..) I can't see any way in sources for the error to be '5' if you really aren't using a debug build. It's only possible if you have patched the sources.. ------------------------------------------------------------------------ [2007-08-12 21:30:06] chris at dented-planet dot net Description: ------------ I don't know if this is considered a bug there there has been a change in behavior in the File Upload handling when uploading a zero-length file. The change happened after PHP 5.2.2 and is in 5.2.4RC1 as well. Note: I am not using a debug build. Reproduce code: --------------- Use this code to upload a zero-length file (I used Firefox 1.5.x): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US"> <head></head> <body> <form method="post" action="<?php echo $_SERVER['PHP_SELF'] ?>" enctype="multipart/form-data"> <input type="file" name="upload_file" /> <br /> <input type="submit" name="submit" value="Submit" /> </form> <br /> <pre> <?php var_dump($_FILES); ?> </pre> </body> </html> Expected result: ---------------- In PHP 5.2.2, the output of var_dump($_FILES) is: array(1) { ["upload_file"]=> array(5) { ["name"]=> string(9) "empty.txt" ["type"]=> string(10) "text/plain" ["tmp_name"]=> string(18) "/var/tmp/phpLAvnSB" ["error"]=> int(0) ["size"]=> int(0) } } In PHP 5.2.3 and later it is: array(1) { ["upload_file"]=> array(5) { ["name"]=> string(9) "empty.txt" ["type"]=> string(0) "" ["tmp_name"]=> string(0) "" ["error"]=> int(5) ["size"]=> int(0) } } Especially, notice the change in "error". ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=42280&edit=1
