If successful, the number ** of bytes written is returned. If an error occurs, NULL is returned. ** ** If the first option argument - MODE - is present, then it must ** be passed an integer value that corresponds to a POSIX mode ** value (file type + permissions, as returned in the stat.st_mode ** field by the stat() system call). Three types of files may ** be written/created: ** ** regular files: (mode & 0170000)==0100000 ** symbolic links: (mode & 0170000)==0120000 ** directories: (mode & 0170000)==0040000 ** ** For a directory, the DATA is ignored. For a symbolic link, it is ** interpreted as text and used as the target of the link. For a ** regular file, it is interpreted as a blob and written into the ** named file. Regardless of the type of file, its permissions are ** set to (mode & 0777) before returning. ** ** If the optional MTIME argument is present, then it is interpreted ** as an integer - the number of seconds since the unix epoch. The ** modification-time of the target file is set to this value before ** returning. ** ** If three or more arguments are passed to this function and an ** error is encountered, an exception is raised. ** ** READFILE(FILE): ** ** Read and return the contents of file FILE (type blob) from disk. ** ** FSDIR: ** ** Used as follows: ** ** SELECT * FROM fsdir($path [, $dir]); ** ** Parameter $path is an absolute or relative pathname. If the file that it ** refers to does not exist, it is an error. If the path refers to a regular ** file or symbolic link, it returns a single row. Or, if the path refers ** to a directory, it returns one row for the directory, and one row for each ** file within the hierarchy rooted at $path. ** ** Each row has the following columns: ** ** name: Path to file or directory (text value). ** mode: Value of stat.st_mode for directory entry (an integer). ** mtime: Value of stat.st_mtime for directory entry (an integer). ** data: For a regular file, a blob containing the file data. For a ** symlink, a text value containing the text of the link. For a ** directory, NULL. ** ** If a non-NULL value is specified for the optional $dir parameter and ** $path is a relative path, then $path is interpreted relative to $dir. ** And the paths returned in the "name" column of the table are also ** relative to directory $dir. */ #include "sqlite3ext.h" SQLITE_EXTENSION_INIT1 #include <stdio.h> #include <string.h> #include <assert.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #if !defined(_WIN32) && !defined(WIN32) # include <unistd.h> # include <dirent.h> # include <utime.h> #else # include "windows.h" # include <io.h> # include <direct.h> # include "test_windirent.h" # define dirent DIRENT # define timespec TIMESPEC # define stat _stat # define mkdir(path,mode) _mkdir(path) # define lstat(path,buf) _stat(path,buf) #endif #include <time.h> #include <errno.h> #define FSDIR_SCHEMA "(name,mode,mtime,data,path HIDDEN,dir HIDDEN)" /* ** Set the result stored by context ctx to a blob containing the ** contents of file zName. */ static void readFileContents(sqlite3_context *ctx, const char *zName){ FILE *in; long nIn; void *pBuf; in = fopen(zName, "rb"); if( in==0 ) return; fseek(in, 0, SEEK_END); nIn = ftell(in); rewind(in); pBuf = sqlite3_malloc( nIn ); if( pBuf && 1==fread(pBuf, nIn, 1, in) ){ sqlite3_result_blob(ctx, pBuf, nIn, sqlite3_free); }else{ sqlite3_free(pBuf); } fclose(in); } /* ** Implementation of the "readfile(X)" SQL function.
