           Summary: wininet:http - test_http_cache() opening the backing
                    file sometimes fails due to a sharing violation on
                    Windows
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2

wininet:http - test_http_cache() opening the backing file sometimes fails due
to a sharing violation on Windows:
http.c:1603: Test failed: Could not create file: 32
http.c:1605: Test failed: file size = 4294967295
http.c:1613: Test failed: file size = 4294967295
http.c:1617: Test failed: Deleting file returned 1(6)
http.c:1623: Test failed: Could not create file: 2
http.c:1625: Test failed: WriteFile failed: 0, 0
http.c:1627: Test failed: CommitUrlCacheEntry failed: 2
http.c:1634: Test failed: HttpSendRequest failed
http.c:1639: Test failed: size = 0
http.c:1641: Test failed: incorrect page data: <html><body>
<h1>Hello world!</h1>
This is a test page for the Wine regression test suite.
</body><
See https://test.winehq.org/data/patterns.html#wininet:http
Where the first failure causes all the other ones and 32 ==
ERROR_SHARING_VIOLATION.
This failure mode has only happened on w1064v1809, w1064-tsign (21H2) and
w1064v21h2 for a total of 8 occurrences between 2022-06-13 and 2022-11-23.
This seems like broken Windows behavior so maybe we should retry after a delay
and a broken()?
