[tor/master] Revert "Use the FILE_SHARE_DELETE flag for CreateFile on a mapping"

I'm reverting this because it doesn't actually make the problem go away.

[tor/master] Use the FILE_SHARE_DELETE flag for CreateFile on a mapping
by nickm＠torproject.org 12 Jun '13

commit 884a0e269c382f9e927d8c8b1ef4ef9d2d48379d Author: Nick Mathewson <nickm(a)torproject.org> Date: Wed Jun 12 09:53:46 2013 -0400 Use the FILE_SHARE_DELETE flag for CreateFile on a mapping A comment by rransom on #8795 taken together with a comment by doorss recorded on #2077 suggest that *every* attempt to replace the md cache will fail on Vista/Win7 if we don't have the FILE_SHARE_DELETE flag passed to CreateFile, and if we try to replace the file ourselves before unmapping it. I'm adding the FILE_SHARE_DELETE, since that's this simplest fix. Broken indexers (the favored #2077 hypothesis) could still cause trouble here, but at least this patch should make us stop stepping on our own feet. Likely fix for #2077 and its numerous duplicates. Bugfix on 0.2.2.6-alpha, which first had a microdescriptor cache that would get replaced before remapping it. --- changes/bug2077_share_delete | 7 +++++++ src/common/compat.c | 2 +- 2 files changed, 8 insertions(+), 1 deletion(-) diff --git a/changes/bug2077_share_delete b/changes/bug2077_share_delete new file mode 100644 index 0000000..71e9160 --- /dev/null +++ b/changes/bug2077_share_delete @@ -0,0 +1,7 @@ + o Major bugfixes (windows): + - Open files to be mapped with FILE_SHARE_DELETE so that we can + replace them before closing the mapping.
