*************************************************************************
|
|
**
|
|
** This is a utility program designed to aid running regressions tests on
|
|
** the SQLite library using data from external fuzzers.
|
|
**
|
|
** 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.
|
|
**
|
|
** DBSQLFUZZ: (Added 2020-02-25)
|
|
**
|
|
** The dbsqlfuzz fuzzer includes both a database file and SQL to run against
|
|
** that database in its input. This utility can now process dbsqlfuzz
|
|
** input files. Load such files using the "--load-dbsql FILE ..." command-line
|
|
** option.
|
|
**
|
|
** Dbsqlfuzz inputs are ordinary text. The first part of the file is text
|
|
** that describes the content of the database (using a lot of hexadecimal),
|
|
** then there is a divider line followed by the SQL to run against the
|
|
** database. Because they are ordinary text, dbsqlfuzz inputs are stored
|
|
** in the XSQL table, as if they were ordinary SQL inputs. The isDbSql()
|
|
** function can look at a text string and determine whether or not it is
|
|
** a valid dbsqlfuzz input.
