[PATCH v3 1/2] ntdll: Allow renaming a file/directory to a different casing of itself.
by Gabriel Ivăncescu 20 Apr '21

20 Apr '21

Renaming a file or directory from e.g. foobar to FooBar (or any other casing change) should work, like on Windows, instead of being a no-op. Clobbering an existing file must also respect the new casing. Note that we only send the different casing (and thus casing_len != 0) if it's actually different. This is important to preserve atomicity of rename() in wineserver in all other cases that don't require this special casing handling. The only extra time rename() is not atomic is when an existing file is clobbered with a different casing, since we have to unlink the old file first, then rename the new file into the new casing, but there's no way around that... Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=46203 Signed-off-by: Gabriel Ivăncescu <gabrielopcode(a)gmail.com> --- We just prepend the unix casing filename (without path) to the wineserver data before the actual unix filename, and add an extra (optional) field `casing_len` which is the length of this data. If there's no casing, this is zero and the behavior is identical to before, which is the default. dlls/ntdll/unix/file.c | 46 ++++++++++++++++++--- server/fd.c | 94 +++++++++++++++++++++++++++++------------- server/protocol.def | 2 + 3 files changed, 107 insertions(+), 35 deletions(-) diff --git a/dlls/ntdll/unix/file.c b/dlls/ntdll/unix/file.c index 9ee5e84..fa604a1 100644 --- a/dlls/ntdll/unix/file.c +++ b/dlls/ntdll/unix/file.c @@ -4508,8 +4508,9 @@ NTSTATUS WINAPI NtSetInformationFile( HANDLE handle, IO_STATUS_BLOCK *io, { FILE_RENAME_INFORMATION *info = ptr;

[tools] winetest/dissect: Fix handling of skipped test unit.
by Francois Gouget 20 Apr '21

close_test_unit() adds an entry in summary.txt for every test unit. So the report parser must set $summary instead of manually adding a redundant summary.txt entry.
