bookmarks: make writing files out avoid ambiguity of file stat Cached attribute repo._bookmarks uses stat of '.hg/bookmarks' and '.hg/bookmarks.current' files to examine validity of cached contents. If writing these files out keeps ctime, mtime and size of them, change is overlooked, and old contents cached before change isn't invalidated as expected. To avoid ambiguity of file stat, this patch writes '.hg/bookmarks' and '.hg/bookmarks.current' files out with checkambig=True.

transaction: avoid ambiguity of file stat at closing transaction Files below, which might be changed at closing transaction, are used to examine validity of cached properties. If changing keeps ctime, mtime and size of a file, change is overlooked, and old contents cached before change isn't invalidated as expected. - .hg/bookmarks - .hg/dirstate - .hg/phaseroots To avoid ambiguity of file stat, this patch writes files out with checkambig=True at closing transaction. checkambig becomes True only at closing (= 'not suffix'), because stat information of '.pending' file isn't used to examine validity of cached properties.
