Bug #75384 [Com]: PHP seems incompatible with OneDrive files on demand

Edit report at https://bugs.php.net/bug.php?id=75384&edit=1 ID: 75384 Comment by: simbiat at bk dot ru Reported by: phpbugs at dougweb dot org Summary: PHP seems incompatible with OneDrive files on demand Status: Open Type: Bug Package: *Directory/Filesystem functions Operating System: Windows 10 PHP Version: 7.1.10 Block user comment: N Private report: N New Comment: I think this is not OneDrive related. I moved htdocs to 1 directory above OneDrive (that is C:\users\username\htdocs) but still get the same error. When I move it to C:\htdocs - it works fine. I think there is something wrong with permissions, that PHP gets from Apache, even though, Apache can access the files normally. Tried setting php.exe to run under admin (Compatibility mode), but that did not help, either. Warning like PHP Warning: Unknown: failed to open stream: Operation not permitted in Unknown on line 0 Only support that PHP can't access the file. And the funny thing is: if I look at the folders in Total Commander it shows them as... Links. And SymLink following is allowed in configuration file.

The problem exist after upgrading Windows fall creators update 1709. I have upgraded 2 PC's to this version. On the first one, the Onedrive update (build 17.3.7073.1013) that supports the "Files on Demand" feature , is installed. On the second one, Onedrive (build 17.3.6998.0830) does not support the "Files on Demand" feature. On both the problem exists. This seems to suggest the cause of the problem is introduced by the Windows update, and is not depending on the Onedrive version. I can also confirm that the problem does not exist on files that are not in a Onedrive directory. ------------------------------------------------------------------------ [2017-10-15 18:01:52] phpbugs at dougweb dot org Description: ------------ It would seem that the new "Files on Demand" feature of OneDrive in the Windows fall update causes issues with PHP's ability to open files. In theory according to MS this should be invisible to applications but there's definitely something screwy going on with PHP. (https://support.office.com/en-us/article/Learn-about-OneDrive-Files-On-Demand-0e6860d3-d9f3-4971-b321-7092438fb38e?ui=en-US&rs=en-US&ad=US&fromAR=1). Any attempt to iterate through files in a folder, or even simply do a "require" results in PHP somehow not being able to see them. This applies even if the files are locally available on the PC, the only thing needed to trigger this is to have Files on Demand enabled and to have the source located somewhere within the OneDrive folder. Moving the source code to any other folder makes things work normally. Weirdly, PHP does seem to be able to read the initial file it's asked to execute, it's only secondary files it's unable to load. This may or may not help debugging, but if I install Ubuntu into Windows 10 via the Windows Store, and execute PHP scripts in the OneDrive folder from Linux (so PHP is using the Linux file APIs, with the MS shim converting them to the Windows ones) then that works fine. Test script: --------------- 1) On a recent Windows Insider Build (or wait until RTM in a few days) 2) Enable OneDrive, and the "Files on Demand" feature Then in your OneDrive folder, create 2 files Foo.php <?php require 'Bar.php'; Bar.php <?php echo 'Require worked'; Then run php Foo.php Expected result: ---------------- See "Require worked" output to the screen Actual result: -------------- PHP Warning: require(Bar.php): failed to open stream: No such file or directory in Foo.php on line 2 Warning: require(Bar.php): failed to open stream: No such file or directory in F oo.php on line 2 PHP Fatal error: require(): Failed opening required 'Bar.php' (include_path='.; C:\php\pear') in Foo.php on line 2 Fatal error: require(): Failed opening required 'Bar.php' (include_path='.;C:\ph p\pear') in Foo.php on line 2 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75384&edit=1
