The way that was achieved was by getting rid of the obscure and not well used functions sqlSafefFrag and sqlDyStringPrintfFrag and replacing them with the plain versions of those functions, since these are not needed anymore. The new version checks for NOSQLINJ in unquoted %-s which is used to include SQL clauses, and will give an error the NOSQLINJ clause is not present, and this will automatically require the correct behavior by developers. sqlDyStringPrint is a very useful function, however because it was not enforced, users could use various other dyString functions and they operated without any awareness or checking for SQL correct use. Now those dyString functions are prohibited and it will produce an error if you try to use a dyString function on a SQL string, which is simply detected by the presence of the NOSQLINJ prefix. diff --git src/hg/lib/syntenyBerk.c src/hg/lib/syntenyBerk.c index 5388bdf..1f2a5fb 100644 --- src/hg/lib/syntenyBerk.c +++ src/hg/lib/syntenyBerk.c @@ -59,31 +59,31 @@ return list; } struct syntenyBerk *syntenyBerkLoadWhere(struct sqlConnection *conn, char *table, char *where) /* Load all syntenyBerk from table that satisfy where clause.
