** SQLite uses this code for testing only. It is not a part of
|
||||
** the SQLite library. This file implements two new TCL commands
|
||||
** "md5" and "md5file" that compute md5 checksums on arbitrary text
|
||||
** and on complete files. These commands are used by the "testfixture"
|
||||
** program to help verify the correct operation of the SQLite library.
|
||||
**
|
||||
** The original use of these TCL commands was to test the ROLLBACK
|
||||
** feature of SQLite. First compute the MD5-checksum of the database.
|
||||
** Then make some changes but rollback the changes rather than commit
|
||||
** them. Compute a second MD5-checksum of the file and verify that the
|
||||
** two checksums are the same. Such is the original use of this code.
|
||||
** New uses may have been added since this comment was written.
