Prevent delta loops on sync operations that might otherwise occur if a sequence of file changes ends with a file back to its original state after a sequence of two or more intermediate states. The is a backport/cherrypick of check-in [141b990722ea81e10e5] Leaf check-in: 285eeba64f user: drh tags: branch-1.19
2012-11-14
20:28
Detect infinite loops in the DELTA table and abort out of content_get() when they are found. Fix an off-by-one error in the version-3 clone protocol. This error might cause an incomplete and corrupt clone if a transfer block fills up just before sending the very last blob. Backport of fixes from 2012-08-23 21:15:36 check-in: 99053ab141 user: drh tags: branch-1.19

Cherrypick changes [0c37874941c8972], [9ba8a393fcc569b], and [ae092ec605eed11] in order to backport the --setmtime option of "fossil update" and the --age and -t options of "fossil ls" to version 1.19. check-in: 773c6c5f2c user: drh tags: branch-1.19

**
** If VFILE.DELETED is true or if VFILE.RID is zero, then the file was either
** removed from configuration management via "fossil rm" or added via
** "fossil add", respectively, and in both cases we always know that

** or on-disk content.
**
** If the size of the file has changed, then we always know that the file




** changed without having to look at the mtime or on-disk content.
**
** The mtime of the file is only a factor if the mtime-changes setting
** is false and the useSha1sum flag is false.  If the mtime-changes
** setting is true (or undefined - it defaults to true) or if useSha1sum
** is true, then we do not trust the mtime and will examine the on-disk
** content to determine if a file really is the same.
**
** If the mtime is used, it is used only to determine if files are the same.
** If the mtime of a file has changed, we still examine the on-disk content
