All README.MSG values are printed prior 34 ** to the start of the test (unless the --quiet option is used). If the 35 ** DB table is empty, then all entries in XSQL are run against an empty 36 ** in-memory database. 37 ** 38 ** This program is looking for crashes, assertion faults, and/or memory leaks. 39 ** No attempt is made to verify the output. The assumption is that either all 40 ** of the database files or all of the SQL statements are malformed inputs, 41 ** generated by a fuzzer, that need to be checked to make sure they do not 42 ** present a security risk. 43 ** 44 ** This program also includes some command-line options to help with 45 ** creation and maintenance of the source content database. The command 46 ** 47 ** ./fuzzcheck database.db --load-sql FILE... 48 ** 49 ** Loads all FILE... arguments into the XSQL table. The --load-db option 50 ** works the same but loads the files into the DB table. The -m option can 51 ** be used to initialize the README table. The "database.db" file is created 52 ** if it does not previously exist. Example: 53 ** 54 ** ./fuzzcheck new.db --load-sql *.sql 55 ** ./fuzzcheck new.db --load-db *.db 56 ** ./fuzzcheck new.db -m 'New test cases' 57 ** 58 ** The three commands above will create the "new.db" file and initialize all 59 ** tables. Then do "./fuzzcheck new.db" to run the tests. 60 ** 61 ** DEBUGGING HINTS: 62 ** 63 ** If fuzzcheck does crash, it can be run in the debugger and the content 64 ** of the global variable g.zTextName[] will identify the specific XSQL and 65 ** DB values that were running when the crash occurred. 66 */ 67 #include <stdio.h> 68 #include <stdlib.h> 69 #include <string.h> 70 #include <stdarg.h> 71 #include <ctype.h> 72 #include "sqlite3.h" 73 #define ISSPACE(X) isspace((unsigned char)(X)) 74 #define ISDIGIT(X) isdigit((unsigned char)(X)) 75 76 77 #ifdef __unix__ 78 # include <signal.h> 79 # include <unistd.h> 80 #endif 81 82 #ifdef SQLITE_OSS_FUZZ 83 # include <stddef.h> 84 # if !defined(_MSC_VER) 85 # include <stdint.h> 86 # endif 87 #endif 88 89 #if defined(_MSC_VER) 90 typedef unsigned char uint8_t; 91 #endif 92 93 /* 94 ** Files in the virtual file system. 95 */ 96 typedef struct VFile VFile; 97 struct VFile { 98 char *zFilename; /* Filename.
