Bug ID: 51813 Summary: python fatal error redirecting stdout to file Product: Wine Version: 6.16 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: xantares09@hotmail.com Distribution: ArchLinux

python exits with a fatal error when the output is redirected to a file

$ wget https://www.python.org/ftp/python/3.9.5/python-3.9.5-embed-win32.zip $ unzip python-3.9.5-embed-win32.zip $ wine python -c 'print("hello world")' > out.txt wine: created the configuration directory '/home/devel/.wine' ... wine: configuration in L"/home/devel/.wine" has been updated. Fatal Python error: init_sys_streams: can't initialize sys standard streams Python runtime state: core initialized OSError: [WinError 6] Invalid handle

Current thread 0x000000d4 (most recent call first): <no Python frame>

whereas it succeeds on stdout or /dev/null: $ wine python -c 'print("hello world")' hello world

I also tried python 3.8.6 and wine 6.15/6.14 without luck

--- Comment #1 from xantares xantares09@hotmail.com --- curiously it works through tee:

$ wine python -c 'print("hello world")' | tee > out.txt

--- Comment #2 from Bernhard Übelacker bernhardu@mailbox.org --- Created attachment 71237 --> https://bugs.winehq.org/attachment.cgi?id=71237 Workaround for redirection at linux side.

As far as I see does python query GetFileType for the handle from stdin which returns in the redirected case FILE_TYPE_DISK. Therefore it looks like python calls GetFileInformationByHandle and expects this to succeed.

In the case of a redirection created by cmd in native or wine this works as expected. But GetFileInformationByHandle fails if the redirection is done at linux side because fd->unix_name gets not set.

Attached patch should demonstrate the issue and possible workaround.

--- Comment #5 from Eric Pouech eric.pouech@gmail.com --- Created attachment 73605 --> https://bugs.winehq.org/attachment.cgi?id=73605 alternative patch

could you test this alternative patch? - we can do better than returning an empty BY_HANDLE_FILE_INFORMATION buffer - and doesn't require heuristics to return empty buffer

Current thread 0x00000024 (most recent call first): <no Python frame>

As a workaround, I have cherry-picked your fix into my branch: https://gitlab.winehq.org/epo/wine/-/commit/cde092dd35463fff95a22f27256f6fe5...

For other readers: This patch fixes the issue in kernelbase by removing unnecessary call to NtQueryInformationFile with FileAllInformation in GetFileInformationByHandle, which fails to retrieve the name (FileNameInformation) of the pipe-file. Instead it queries FileBaicInformation, FileStandardInformation and FileInternalInformation which provide sufficient information without failing.

Alternatively, there is also this patch: https://www.winehq.org/pipermail/wine-devel/2020-September/174029.html

This patch solves the issue in wineserver implementing NtQueryInformationFile FileNameInformation for pipes.

I don't see any change to GetFileInformationByHandle. It still uses FileAllInformation.
