Bug #74283 [Opn->Nab]: Cannot write nor copy to file names ending with dot.

Edit report at https://bugs.php.net/bug.php?id=74283&edit=1 ID: 74283 Updated by: ab@php.net Reported by: pavel dot hlousek at gmail dot com Summary: Cannot write nor copy to file names ending with dot. -Status: Open +Status: Not a bug Type: Bug Package: Filesystem function related Operating System: Windows PHP Version: 7.1.3 Block user comment: N Private report: N New Comment: Thanks for the report. The behavior change is intentional. Paths with trailing dots are invalid on Windows. Why it happens in 7.1 is, that we are now occasionally forced to use the long path prefix and thus have to be more strict with the path normalization. Otherwise, if "test" exists, accessing "test." is tolerated.

Previous Comments: ------------------------------------------------------------------------ [2017-03-21 12:24:57] pavel dot hlousek at gmail dot com Description: ------------ PHP5.6 handled the same way file names without extension written either "filename" or "filename." (with dot character at the end of the file name). PHP7.1.3 handles both forms of file name only in some of the functions but throws warning "Permission denied" in others. OK functions: file_get_contents, file_exists Bad functions: file_put_contents, copy, rename Test script: --------------- 1) file_put_contents('test.', 'test.'); 2) file_put_contents('test.txt', 'test.txt'); copy('test.txt', 'test.'); 3) file_put_contents('test.txt', 'test.txt'); rename('test.txt', 'test.'); Expected result: ---------------- 1) File "test" written to file system with "test." content. 2) File "test" exists in file system with "test.txt" content. 3) File "test" exists in file system with "test.txt" content. Actual result: -------------- 1-3) Warning: Permission denied. Files not created. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74283&edit=1
