Description
Hi,
well, it's a bit hard to explain. The Qt 5.15.1 upgrade broke our test environment (no problem with Qt 5.13 so far). We cross-compile our application (Linux host, MinGW 64 build), and we run our tests on Linux host with wine.
We noticed "Broken filename passed to function" errors in the logs, and I managed to find a bug in the QFileInfo::canonicalFilePath()'s function. When the path is relative and contains a "../" inside, the resolved path will be wrong.
Example code to trigger the issue:
#include <QCoreApplication> #include <QDebug> #include <QDirIterator> #include <QFileInfo> #include <iostream> int main(int argc, char *argv[]) { QCoreApplication a(argc, argv); Q_UNUSED(a) const auto somePath = qEnvironmentVariable("SOME_PATH", QStringLiteral("/tmp")); QFileInfo info(somePath); std::cout << "cannonicalFilePath " << info.canonicalFilePath().toStdString() << std::endl; QDirIterator it(info.canonicalFilePath(), QDirIterator::Subdirectories); while (it.hasNext()) { QString file = it.next(); if (it.fileInfo().isFile()) { std::cout << " file " << file.toStdString() << std::endl; } } return 0; }
Output when it's working as expected:
$SOME_PATH=$PWD/ /usr/bin/wine ./brokenfilenameqt5151.exe 0068:err:ole:start_rpcss Failed to start RpcSs service cannonicalFilePath Z:/mnt/home/tomi/zwa/projects/adp-developing-2.0/source/adp/brokenfilenameqt5151/aaa file Z:/mnt/home/tomi/zwa/projects/adp-developing-2.0/source/adp/brokenfilenameqt5151/aaa/brokenfilenameqt5151.exe file Z:/mnt/home/tomi/zwa/projects/adp-developing-2.0/source/adp/brokenfilenameqt5151/aaa/commands.txt file Z:/mnt/home/tomi/zwa/projects/adp-developing-2.0/source/adp/brokenfilenameqt5151/aaa/main.o file Z:/mnt/home/tomi/zwa/projects/adp-developing-2.0/source/adp/brokenfilenameqt5151/aaa/Makefile file Z:/mnt/home/tomi/zwa/projects/adp-developing-2.0/source/adp/brokenfilenameqt5151/aaa/strace_fail.txt file Z:/mnt/home/tomi/zwa/projects/adp-developing-2.0/source/adp/brokenfilenameqt5151/aaa/strace_success.txt file Z:/mnt/home/tomi/zwa/projects/adp-developing-2.0/source/adp/brokenfilenameqt5151/aaa/winedebug_fail.txt file Z:/mnt/home/tomi/zwa/projects/adp-developing-2.0/source/adp/brokenfilenameqt5151/aaa/winedebug_success.txt
Output when it is not working:
$SOME_PATH=$PWD/../aaa /usr/bin/wine ./brokenfilenameqt5151.exe 0068:err:ole:start_rpcss Failed to start RpcSs service cannonicalFilePath Z:/mnt/home/tomi/zwa/projects/adp-developing-2.0/source/adp/brokenfilenameqt5151/aaa../aaa $ls $PWD/../aaa -1 brokenfilenameqt5151.exe commands.txt main.o Makefile strace_fail.txt strace_success.txt winedebug_fail.txt winedebug_success.txt
The problem is that the canonical file path is wrong.
Z:/mnt/home/tomi/zwa/projects/adp-developing-2.0/source/adp/brokenfilenameqt5151/aaa missind a '/' here ../aaa
I have also attached a sample project with debug outputs with strace and wine logs.
Most probably this was an issue with our qmltestcase test apps, where the -import path stopped working for us, and had to change the deployment for our tests to be able to run it them with wine.
