| ************************************************************************* |
| ** |
| ** This is a utility program designed to aid running regressions tests on |
| ** the SQLite library using data from an external fuzzer, such as American |
| ** Fuzzy Lop (AFL) (http://lcamtuf.coredump.cx/afl/). |
| ** |
| ** This program reads content from an SQLite database file with the following |
| ** schema: |
| ** |
| ** CREATE TABLE db( |
| ** dbid INTEGER PRIMARY KEY, -- database id |
| ** dbcontent BLOB -- database disk file image |
| ** ); |
| ** CREATE TABLE xsql( |
| ** sqlid INTEGER PRIMARY KEY, -- SQL script id |
| ** sqltext TEXT -- Text of SQL statements to run |
| ** ); |
| ** CREATE TABLE IF NOT EXISTS readme( |
| ** msg TEXT -- Human-readable description of this test collection |
| ** ); |
| ** |
| ** For each database file in the DB table, the SQL text in the XSQL table |
| ** is run against that database. All README.MSG values are printed prior |
| ** to the start of the test (unless the --quiet option is used). If the |
| ** DB table is empty, then all entries in XSQL are run against an empty |
| ** in-memory database. |
| ** |
| ** This program is looking for crashes, assertion faults, and/or memory leaks. |
| ** No attempt is made to verify the output. The assumption is that either all |
| ** of the database files or all of the SQL statements are malformed inputs, |
| ** generated by a fuzzer, that need to be checked to make sure they do not |
| ** present a security risk. |
| ** |
| ** This program also includes some command-line options to help with |
| ** creation and maintenance of the source content database. The command |
| ** |
| ** ./fuzzcheck database.db --load-sql FILE... |
| ** |
| ** Loads all FILE... arguments into the XSQL table. The --load-db option |
| ** works the same but loads the files into the DB table. The -m option can |
| ** be used to initialize the README table. The "database.db" file is created |
| ** if it does not previously exist. Example: |
| ** |
| ** ./fuzzcheck new.db --load-sql *.sql |
| ** ./fuzzcheck new.db --load-db *.db |
| ** ./fuzzcheck new.db -m 'New test cases' |
| ** |
| ** The three commands above will create the "new.db" file and initialize all |
| ** tables. Then do "./fuzzcheck new.db" to run the tests. |
| ** |
| ** DEBUGGING HINTS: |
| ** |
| ** If fuzzcheck does crash, it can be run in the debugger and the content |
| ** of the global variable g.zTextName[] will identify the specific XSQL and |
| ** DB values that were running when the crash occurred. |
