* rand: rearrange code to test fixnump first.Kaz Kylheku2025-03-231-46/+46
| | | | | | * rand.c (random): The fixnump is going to come up more often than bignum, and is also fast to test for since fixnums are identified by just the tag in value word.
* rand: use PRNG bits more economically for small moduli.Kaz Kylheku2025-03-211-1/+149
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rand function always calls rand32 at least one for each call, even for small moduli that need only a few pseudo-random bits. For instance when the modulus is 2, the function requires only one pseudo-random bit from the PRNG, yet it takes 32 and throws away 31. With this commit, that changes. For moduli of 65536 or smaller, the bits are used more efficiently; and for a modulus of 2, the function can satisfy 32 calls using the bits of a single rand32_t word: one stepping of the WELL512a PRNG. * rand.c (struct rand_state): New member, shift. Holds the shift register for rand/random to take bits from, replenished from rand32() when it runs out. The shift register detects when it runs out of bits in a clever way, without any additional variable. The register is regarded as being 33 bits wide, with a top bit that is always 1. When the register is empty, a 32 bit word is taken from the PRNG. The required random bits are taken from the word, and it is then shifted to the right. (We take only power-of-two amounts out of the shift register: 1, 2, 4, 8 or 16 bits). Even the smallest shift produces enough room that the 33rd bit can be added to the word, into its shifted position. After that, the shift register is considered to have enough bits for a given modulus if its value is less than equal to the mask. I.e if we were to take bits from it, we would be including the unconditional signaling bit. At that point we clobber the shift register with a new set of 32 bits from the PRNG, take the random bits we need, shift it to the right and add the signaling bit. (opt_noshift): New static variable; indicates whether we are in compatibility mode, requiring the shift register optimization to be defeated. (make_random_state): Initialize shift register to 0 in several places. (random): Implement various small modulus cases. There are specific cases for moduli that are exactly 65536, 256, 16, 4, 3 and 2. The in-between cases are handled by shifting the bits in the same amounts as the next higher power of two from this list of sizes: 16, 8, or 4 bits. For these cases, we calculate the smallest Mersenne modulus which covers the bits of the actual moduls and use that for rejecting potential values, just as we do in the general large modulus case. For instance if the modulus is 60 (range 0 to 59), that lands into the 8 bit shift range: we pull 8 bits at a time from the shift register. But the modulus 60 is covered by the six bit mask 63. We mask each 8 bit value with 63, and if it is in the required range 0 to 59, we accept it, otherwise draw another 8 bits. (rand_compat_fixup): Initialize opt_noshift to 1 if the requested compat version is 299 or less. * tests/012/sort.tl: Fix one test case involving shuffled data. The shufle function uses rand with small moduli, so its behavior changes for the same PRNG sequence. * tests/013/maze.expected: Likewise, the generated pseudo-random maze in the maze test case is different now; we must update to the new expected output. * txr.1: Document that a value of 299 or less of the compatibility -C option has an effect on rand.

| | | | | | | | | | | * rand.c (random): The msb_rand_mask calculation shifts by 32 when msb_rand_bits is zero, like when the modulus is (expt 2 32). By fluke, this has been treated as a zero bit shift on 64 bit intel, so the correct mask was calculated. However, in a PPC64 build, it yields zero. Instead, we calculate the required shift by negating the bit count, in unsigned semantics, and then reducing modulo 32. This gives us the correct value from 0 to 31, resulting in the correct mask.

The struct type system allows struct types to be defined for symbols like regex or str, which are used by built-in or cobj types. This is a bad thing. What is worse, structure instances are COBJ types which identify their type using the COBJ class symbol mechanism. There are places in the C implementation which assume that when a COBJ has a certain class symbol, it is of a certain expected type, which is totally different from and incompatible form a struct instance. User code can define a structure object which will fool that code. There are multiple things going on in this patch. The major theme is that the COBJ representation is changing. Instead of a class symbol, COBJ instances now carry a "struct cobj_class *" pointer. This pointer is obtained by registration via the cobj_register function. All modules must register their class symbols to obtain these class handles, which are then used in cobj() calls for instantiation. The CPTR type was identical to COBJ until now, except for the type tag. This is changing; CPTR objects will keep the old representation with the class symbol. commit 20fdfc6008297001491308849c17498c006fe7b4 Author: Kaz Kylheku <kaz@kylheku.com> Date: Thu Jul 8 19:17:39 2021 -0700 * ffi.h (carray_cls): Declared. * hash.h (hash_cls): Declared.

This requires changes in a large number of places. In a few places, additional functions acquire a self argument. The ffi module has the most extensive example of this. Some functions mention their name in a larger string, or have scattered literals giving their name; with the introduction of the self local variable, these are replaced by references to self. In the following changelog, the notation TS stands for "take self argument", meaning that the functions acquires a new "val self" argument. The notation DS means "define self": the functions in question defines a self variable, which they pass down. The notation PS means that the functions pass down an existing self variable to functions that now require it. * args.h (args_count): TS. * arith.c (c_unum, c_num): TS.

* safety: fix type tests that code can subvert.Kaz Kylheku2019-09-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes numerous instances of a safety hole which involves the type of a COBJ object being tested to be of a given class using logic that can be subverted by the definition of a like-named struct. Specifically logic like (typeof(obj) == hash_s) is broken, because if a struct type called hash is defined, then the test will yield true for instances of that struct type. Those instances can then be passed into code that only works on COBJ hashes, and relies on this test to reject invalid objects. * ffi.c (make_carray): Replace fragile test with strong one, using new cobjclassp function. * hash.c (hashp): Likewise. * lib.c (class_check): The expression used here for the type test moves into the new function cobjclassp and so is replaced by a call to that function. (cobjclassp): New function. * lib.h (cobjclassp): Declared. * rand.c (random_state_p): Replace fragile test using cobjclassp. * regex.c (char_set_compile): Replace fragile typeof tests for character type with is_chr. (reg_derivative, regexp): Replace fragile test with cobjclassp. * struct.c (struct_type_p): Replace fragile test with cobjclassp.
* Fix some instances of 4 bytes = 32 bits assumption.Kaz Kylheku2019-01-231-6/+6
| | | | | | | | | | | | | | | | | * hash.c (equal_hash, eql_hash, cobj_eq_hash_op, hash_hash_op): Multiply object size by CHAR_BIT and switch on number of bits, rather than bytes. * sysif.c (off_t_num): Likewise. * arith.c, ffi.c, itypes.c, rand.c: In numerous #if directive, fix size tests from bytes to bits. * configure: in the test that detects integer types, and in the test for enabling large file offsets, detect one more variable from the system: the value of CHAR_BIT. This turns into SIZEOF_BYTE. We use that value instead of a hard-coded 8.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MPI has a mp_size type for sizing of the digit arrays and some other uses. It is not consistently used. Moreover, it is typedef'd as a signed type. The type int is used for iterating over digits, instead of the matching mpi_size type. The int type is used as a size argument in some functions, and in functions that return the number of bits. This patch makes mp_size unsigned and replaces most uses of int with a more appropriate type. Because mp_size is now used for indexing, and is unsigned, some downward loop termination tests have to be changed; the always true condition ix >= 0 cannot be used. * arith.c (width): Use mp_size for local variable which iterates over digits inside mpi_int object, and for bit count. Use unum to convert bit count to Lisp integer: mp_size could be out of range of cnum. * mpi/mpi-types.h (mp_size): Typedef to unsigned. (MP_SIZE_MAX): New macro. (MP_DIGIT_BIT, MP_WORD_BIT): Cast the value to mp_size rather than to int. * mpi/mpi.c (s_mp_defprec): Declare variable as mp_size. (s_mp_setz, s_mp_copy, mp_size, s_highest_bit_mp, s_mp_set_bit, s_mp_ispow2, s_mp_outlen, mp_set_int, mp_set_uintptr, mp_set_double_intptr, mp_expt, mp_sqrt, mp_exptmod, mp_hash, mp_gcd, mp_shift, mp_bit, mp_to_double, mp_print, mp_read_signed_bin, mp_signed_bin_size, mp_read_unsigned_bin, mp_unsigned_bin_size, mp_to_unsigned_bin, mp_to_unsigned_buf, mp_count_bits, mp_is_pow_two, mp_read_radix, mp_radix_size, mp_value_radix_size, mp_toradix_case, s_mp_setz, s_mp_copy, mp_size, s_highest_bit_mp, s_mp_set_bit, s_mp_mul_2, s_mp_mod_2d, s_mp_div_2d, s_mp_div_d, s_mp_sqr, s_mp_sqr, s_mp_div, s_mp_cmp, s_mp_cmp_d, s_mp_ispow2, s_mp_outlen): In all these functions, use size_t for external size, mp_size for number of digits and bits, in return values, arguments and local variables. Tests in descending loops are adjusted for unsigned logic. * mpi/mpi.h (mp_get_prec, mp_set_prec, mp_read_signed_bin, mp_signed_bin_size, mp_read_unsigned_bin, mp_unsigned_bin_size, mp_to_unsigned_buf, mp_count_bits, mp_is_pow_two, mp_radix_size, mp_value_radix_size): Declarations updated. * mpi/mplogic.c (mpl_not, mpl_and, mpl_or, mpl_xor, mpl_rsh, mpl_lsh, mpl_num_set, mpl_num_clear, mpl_parity): Just like in mpi.c * rand.c (make_random_state): Use mp_size and ucnum for local variables holding digit and bit counts. * sysif.c (off_t_num): Use mp_size for digit count.
