From 20a8a277ee0d507d2b9a369ab0c41d23ab8b2291 Mon Sep 17 00:00:00 2001 From: Friedemann Kleint Date: Tue, 24 Oct 2017 13:52:51 +0200 Subject: tst_qfileinfo: Refactor ntfsJunctionPointsAndSymlinks() Move the creation of the symbolic link/junction from the _data() slot into the actual test function. The parameters are passed by a newly introduced struct. This ensures only the symbolic links/junctions that are actually needed are created. It can then no longer happen that filtering for one data row invokes recursive deletion of the mountpoint junction. Also use of the newly introduced convenience createSymbolicLink() in canonicalFilePath() Task-number: QTBUG-63989 Change-Id: Ia78fd4ad6097136934ab5a375f4c352713d0f115 Reviewed-by: Orgad Shaneh --- tests/shared/filesystem.h | 32 ++++++++++++++++++++++++-------- 1 file changed, 24 insertions(+), 8 deletions(-) (limited to 'tests/shared') diff --git a/tests/shared/filesystem.h b/tests/shared/filesystem.h index 73d7d6523c..9f4527a992 100644 --- a/tests/shared/filesystem.h +++ b/tests/shared/filesystem.h @@ -80,7 +80,7 @@ public: } #if defined(Q_OS_WIN) && !defined(Q_OS_WINCE) && !defined(Q_OS_WINRT) - static void createNtfsJunction(QString target, QString linkName) + static DWORD createNtfsJunction(QString target, QString linkName, QString *errorMessage) { typedef struct { DWORD ReparseTag; @@ -97,14 +97,22 @@ public: DWORD returnedLength; wchar_t fileSystem[MAX_PATH] = L""; PREPARSE_MOUNTPOINT_DATA_BUFFER reparseInfo = (PREPARSE_MOUNTPOINT_DATA_BUFFER) reparseBuffer; + DWORD result = ERROR_SUCCESS; QFileInfo junctionInfo(linkName); linkName = QDir::toNativeSeparators(junctionInfo.absoluteFilePath()); - - GetVolumeInformationW( (wchar_t*)linkName.left(3).utf16(), NULL, 0, NULL, NULL, NULL, - fileSystem, sizeof(fileSystem)/sizeof(WCHAR)); - if(QString().fromWCharArray(fileSystem) != "NTFS") - QSKIP("This seems not to be an NTFS volume.
