* QFileInfo: Fail faster when stat'ing filepath on a disconnected driveVolker Hilsheimer2020-07-291-6/+8
| | | | | | | | | | | | | The Windows implementation of QFileSystemEngine tries hard to fill the metadata for a file, even if GetFileAttributesEx returns with error. This is good in many situations, but when the error code indicates that the drive on which the file resides has been disconnected, then we should fail quickly.

* QFile::moveToTrash: work with relative file paths on WindowsVolker Hilsheimer2020-05-071-2/+2
| | | | | | | | | | | | | | | | | | | | The system APIs expect an absolute "display name" of the file path, so make it absolute. The test was overly tolerant in accepting failure, as a QStorageInfo initialized with a file path that doesn't exist is invalid, and thus always different from the QStorageInfo of the home directory. Fix the test to compare only valid QStorageInfo objects, and postpone the check until the file we want to move has been created.

* On Windows 7, fall back to SHFileOperation to avoid confirmation dialogsVolker Hilsheimer2020-02-071-63/+69
| | | | | | | | | | | | | | | | | | | | Moving a file to the trash should preferably done via IFileOperation. However, the implementation on Windows 7 ignores the operation flags that request the shell not to show any confirmation dialogs or other UI elements. SHFileOperation is an old API that doesn't show any UI, but has the limitation that it doesn't report the location of the file in the trash after the move. So an application cannot restore the file, but the user can do so via Explorer. Overall, the better compromise is to not have dialogs at the expense of not being able to report the new path. This allows us to run the unit test on Windows 7 as well. Change-Id: Ib8e651a69e2c6750f668b52d2a70925d156cc8ae Fixes: QTBUG-81927 Reviewed-by: Vitaly Fanaskov <vitaly.fanaskov@qt.io>
* Implement moving of a single file system entry to the trashVolker Hilsheimer2020-01-301-0/+192
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements the operation for Windows, macOS, and Unix, for now only as a private API (since QFileSystemEngine is private). This adds the capability as a testable function; public API to be agreed on and added in a separate commit. The Unix implementation follows the freedesktop.org specification [1] version 1.0. [1] https://specifications.freedesktop.org/trash-spec/trashspec-1.0.html On macOS and Windows, native APIs are used, with each having some limitations: * on macOS, the file in the trash won't have a "put back" option, as we don't use Finder automation, for the reasons provided in the comments * on Windows, we might not be able to use the modern IFileOperation API, e.g. if Qt is built with mingw which doesn't seem to provide the interface definition; the fallback doesn't provide access to the file name in the trash The test case creates files and directories, and moves them to the trash. As part of the cleanup routine, it deletes all file system entries created. If run on Windows without IFileOperations support, this will add a file in the trash for each test run, filling up hard drive space.

* QFileSystemEngine: Consistently check for invalid file namesUlf Hermann2019-10-241-1/+26
| | | | | | | | | | | | | | stat() and friends expect a null-terminated C string. There is no way to generate anything useful from a string that has null bytes in the middle. It's important to catch this early, as otherwise, for example, a QDir::exists() on such a path can return true, as the path is silently truncated. Extend the checks for empty file names to windows and add checks for null bytes. Change-Id: Ie9794c3a7c4fd57f9a66bdbbab8b45a08b6f9170 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | Without this change, the target of a symbolic link that points to a UNC share would include UNC in the target path, and not be correctly made absolute. Add a relevant test case, and use the opportunity to factor out the helper code that creates NTFS symlinks into a function that takes care of error handling.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rename(2) system call overwrites, so instead of using it, we try to use the link/unlink pair. This works for regular cases, but can fail if trying to change case in case-insensitive filesystems, if we're operating on a non-Unix filesystem (FAT) or, on Linux, if the file doesn't belong to the calling user (BSDs permit this). For those cases, we fall back to rename(2). That means there's a race condition if a new file is created there. But we at least reduce the likelihood of that happening for regular files.

* | Simplify fileTimeToQDateTime() by having it return a UTC timeEdward Welbourne2017-01-111-8/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This avoids so many complications. The prior code, using SystemTimeToTzSpecificLocalTime(), lead to unhelpful results when the QDateTime() implementation used MS-POSIX's defective mktime(). Although SystemTimeToTzSpecificLocalTime() is actually more correct, we were getting inconsistent results by mixing the two: and eliminating the use of mktime() turns out to be decidedly tricky. So, to avoid inconsistency, stick with a UTC time (which is what FILETIME is defined as). Change QFileInfo's methods to explicitly convert .toLocalTime() where appropriate and document that these methods do indeed return local time (as we conjecture has been taken for granted by callers). Also added a regression test for the reported case of this going wrong. A time-stamp from before Russia's (permanent, not DST) change of TZ could end up inconsistently handled between file-system meta-data and raw date-time APIs, due to cross-talk between different MS-Win time APIs. [ChangeLog][QtCore][QFileInfo] Made sure that all file lifecycle times are in local time. This was probably true before, but is now explicit.
