-*************************************************************************
-**
-** This is a utility program designed to aid running the SQLite library
-** against an external fuzzer, such as American Fuzzy Lop (AFL)
-** (http://lcamtuf.coredump.cx/afl/). Basically, this program reads
-** SQL text from standard input and passes it through to SQLite for evaluation,
-** just like the "sqlite3" command-line shell. Differences from the
-** command-line shell:
-**
-** (1) The complex "dot-command" extensions are omitted. This
-** prevents the fuzzer from discovering that it can run things
-** like ".shell rm -rf ~"
-**
-** (2) The database is opened with the SQLITE_OPEN_MEMORY flag so that
-** no disk I/O from the database is permitted. The ATTACH command
-** with a filename still uses an in-memory database.
-**
-** (3) The main in-memory database can be initialized from a template
-** disk database so that the fuzzer starts with a database containing
-** content.
-**
-** (4) The eval() SQL function is added, allowing the fuzzer to do
-** interesting recursive operations.
-**
-** (5) An error is raised if there is a memory leak.
-**
-** The input text can be divided into separate test cases using comments
-** of the form:
-**
-** |****<...>****|
-**
-** where the "..." is arbitrary text. (Except the "|" should really be "/".
-** "|" is used here to avoid compiler errors about nested comments.)
-** A separate in-memory SQLite database is created to run each test case.
-** This feature allows the "queue" of AFL to be captured into a single big
-** file using a command like this:
-**
-** (for i in id:*; do echo '|****<'$i'>****|'; cat $i; done) >~/all-queue.txt
-**
-** (Once again, change the "|" to "/") Then all elements of the AFL queue
-** can be run in a single go (for regression testing, for example) by typing:
-**
-** fuzzershell -f ~/all-queue.txt
-**
-** After running each chunk of SQL, the database connection is closed. The
-** program aborts if the close fails or if there is any unfreed memory after
-** the close.
-**
-** New test cases can be appended to all-queue.txt at any time. If redundant
-** test cases are added, they can be eliminated by running:
-**
-** fuzzershell -f ~/all-queue.txt --unique-cases ~/unique-cases.txt
