-To run the tests, just do a "make check" in the tests subdirectory.
-On the CPlant alpha systems, 3 of the 7 tests in test_all.pl are excluded
-due to known problems (problems as of the date of writing this; they
-may have since been fixed). You can also manually run the individual
-tests or ./test_all.pl. If you are running on CPlant, you need to
-run test_all.pl with a -alpha argument. Either "make check" or
-test_all.pl will run the 7 basic functionality tests (explained
-below) and report the total number of passes and failures.

------------------------SCRIPTS---------------------------------
-
-There are a total of 8 scripts: test_copy.pl, test_list.pl,
-test_getcwd.pl, test_stats.pl, test_stdfd.pl, test_path.pl,
-populator.pl, and verifier.pl. All but the last two scripts
-are ran with the test_all.pl script. Here is an explanation
-of the scripts. All scripts take an optional "-alpha" arg
-for running the scripts in an alpha/cplant environment. The
-alpha arg makes certain assumptions about the running of the
-environment; for example, it does not initilization and it
-starts off the test driver with yod.
-
-test_copy.pl <src> <dest> : This copies a file from src to dest.
- : It runs a system cmp to verify that
- : the two files are equivalent
-
-test_list.pl [-p] <dir> : This comes in two forms.
-test_list.pl [-p] <fstype:mdir> <dir> : In the first form, it will
- : parse through the getdirentries
- : result in order to generate a
- : a listing. If the -p option is
- : given, it will print out the
- : listing. In the second form, it
- : mounts mdir into dir and then does
- : the listing
-
-test_getcwd.pl <dir> : Tests getcwd by verifying that setting the current
- : working directory to dir and then calling getcwd
- : returns dir
-
-test_stats.pl <file> : Verifies that the set of stat calls (stat, fstat,
- : fstatvfs, statvfs) return the same set of stats for file
- : and that the calls return the same items as Perl's stat
- : call (which would use a native library and not libsysio)
-
-test_stdfd.pl <file> : Verified that stdin, stdout, and stderr can be opened and
- : either written to or read from
-
-test_path.pl <path1> <path2> ... : Print each path listed and its type.
- : If no paths are given, paths are read
- : from stdin until a "quit" is given
-
-populator.pl [-seed seed] : Create a file and populate with random numbers.
- [-file filename] : Will use the given seed for the random number
- [-bytes bytes] : generator if it is given, otherwise it uses the
- : the current time as a seed. The seed used is
- : returned. If no filename is given, the file
- : will be named randfile.seed.procnum, where seed
- : is the seed used and procnum is the process number
- : of the script. If no bytes are given, 1024 bytes
- : are written. All write commands use libsysio
-
-
-verifier.pl <-seed seed> <-file fname> : Verifies that all bytes in the file fname
- : (which was created with populator) match the
- : random numbers which would have been used with
- : the populator, using the given seed.
-
-
-
------------------------------TEST DRIVER---------------------------------
-
-
-There are 6 basic commands for the test driver, CALL, PRINT,
-ALLOC, FREE, HELP, and exit (EXIT, quit, or QUIT will also work).
-
-CALL is the main command for running libsysio calls. The format
-will depend on the particular libsysio command being ran.
-Basically, the format is CALL cmd args. The available commands
-used with CALL are (in no particular order):
-
-fstat iwrite read chdir
-fstatvfs iwritev readv chmod
-fsync list rmdir chown
-ftruncate lseek sizeof close
-getcwd lstat stat cmpstr
-getdirentries mkdir statvfs creat
-init mknod symlink debug
-ioctl mount truncate dup
-iodone open umask dup2
-iowait umount endian ipread
-printline unlink ipreadv pread
-write fcntl ipwrite preadv
-writev fdatasync ipwritev pwritev
-fill iread pwrite ireadv
-
-The specifics of the commands are explained later.
-
-The return value from a command can be saved and referenced later
-by using a syntax similar to $foo = x. Commands can be combined, such
-as:
-
-CALL fstat ( $fd = CALL open foo ) ( $buf = ALLOC 128 ),
-
-with some cautionary notes. First, everything needs to be
-seperated by a space. File names with spaces in them need to be quoted,
-as in:
-
-$fd = CALL open "file with spaces" O_RDONLY
-
-Second, any value that is used needs to be identified with an identifier.
-In other words, the command:
-
-$buf = ALLOC ( CALL sizeof stat )
-
-will not work, but the command
-
-$buf = ALLOC ( $size = CALL sizeof stat )
-
-will.
-
-
-All commands return a 4 digit status code. The codes are:
-
-0000 : Success. This does NOT necessarily mean that the libsysio
- : command returned success, only that there were no errors
- : in issuing the command to libsysio. To get the result of
- : the libsysio command, use PRINT $$ . PRINT $errno will return
- : the last error code.
-0x001 : Invalid arguments given to command
-0x002 : Invalid command issued
-0x004 : Invalid variable identifier given
-
-
-ALLOC takes a size argument and an optional alignment argument.
-FREE takes the variable to free as an argument.
-HELP without any arguments displays the list of commands.
-HELP <cmd> will give information on the specific command
-
-PRINT take several forms. To just print out a variable, type
-PRINT $var-name. If the variable is an integer, it will return
-the integer. If it is a string, it will print out the string.
-If it is a buffer, it will print out the buffer as a series of
-hex digits. Note for most buffers, the test driver will not
-know what it contains--just because it should contain a string
-does not mean that the driver will know that.
-
-The other form of PRINT is:
-
-PRINT $var_name <offset> <length> <type>
-
-which will print out length units of the given type starting at
-the given offset. The length is the total length in bytes, so
-for an integer, a length of 4 would only print out one integer.
-The length argument is ignored for strings. Allowable types are
-INT SHORT CHAR and LONG.
-
-For most of the CALL commands, their format is similar to the
-related sysio call. The ones that do not have a corresponding
-sysio call are listed below:
-
-init: This MUST be called prior to any sysio calls. It initilizes
- : libsysio
-
-printline: If debugging is turned on, this will print a line number
- : with any debug lines
-
-fill <val> <type> <size> <offset> <buf>: Fills buffer buf with size
- : bytes of val starting at
- : buf+offset. The type of val
- : can be UINT. STR, or PTR and
- : is given by the type arg
-
-list <dir>: Lists contents of dir. If no dir is given, uses cwd
-
-debug <num>: Sets debug level to num
-
-sizeof <obj>: Gives the size of the obj. Valid objs are char, int,
- : long, flock, stat, and statvfs
-
-endian: returns 0 if the machine is little endian, one otherwise
-
-cmpstr <buf1> <buf2>: Issues a strcmp call on the two buffers to
- : see if they are the same. Returns 0 for a
- : match
