The <dirent.h> header is included all over the place because
it is needed by a single declaration in stream.h. That
declaration is for a function that is only called within
stream.c, so we make it internal. Now only stream.c has
to include <dirent.h>.

VM machine code is endian-specific: it consists of 32 bit
instruction words which are 32 bit in the local byte order.
Thus code assembled on a little-endian machine won't run
on a big endian-machine, or vice versa: unless we identify
the situation and byte-swap the code when we load it.
* buf.c (buf_swap32): New function.
* buf.h (buf_swap32): Declared.
* parser.c (read_file_common): Decode the third element from
the version: a Boolean indicating big endian, if true.
If the object file's endian is opposite from our endian, then
byte swap the code.
* itypes.c (itypes_init): Oops, calculation of
itypes_little_endian was broken due to classic C =/== typo.
Luckily, nothing has used this flag so far; it's been waiting
for this first use. I caught this due to testing on a PPC64
box.
* share/txr/stdlib/compiler.tl (%big-endian%, %tlo-ver%): New
variables.
(usr:compile-file): The file version comes from %tlo-ver% now,
which includes the big-endian flag.

There is an issue with the printer in that it produces
output whereby objects continue on the same line after
a multi-line object, e.g:
(foo (foobly bar
xyzzy quux) (oops same
line))
rather than:
(foo (foobly bar
xyzzy quux)
(oops same line))
There is a simple fix for this: set a flag to force
a line break on the next width-check operation whenever
an object has been broken into multiple lines.
width-check can return a Boolean indication whether
it generated a line break, and so aggregate object
printing routines can tell whether their object
has been broken into lines, and set the flag.
* stream.h (struct strm_base): New member, force_break.
(force_break): Declared.
* stream.c (strm_base_init): Extent initializer to cover
force_break flag.
(put_string, put_char): Clear the force_break flag whenever
we hit column zero.
(width_check): If indent mode is on, and force_break is
true, generate a break. Clear force_break.
(force_break): New function.
(stream_init): Register force-break intrinsic.
* buf.c (buf_print): Set the force break flag if the buffer
was broken into multiple lines.
* hash.c (hash_print_op): Set the force break flag if the
hash was broken into multiple lines.
* lib.c (obj_print_impl): Same logic for lists.
* struct.c (struct_inst_print): Same logic for structs.
* tests/009/json.expected, tests/011/macros-2.expected,
tests/012/struct.tl, tests/017/glob-zarray.expected:
Update expected textual output to reflect new formatting.

* buf.c (buf_get_bytes): Fix off-by-one test for reading past
end of buffer. This prevents, e.g. a buf-get-u32
from the last four bytes of a buffer (or from a four-byte-long
buffer, period).

The purpose of this commit is to address certain situations in
which code is wrongly relying on a cnum value being in the
fixnum range (NUM_MIN to NUM_MAX), so that num_fast can safely
be used on it.
One wrong pattern is that c_num is applied to some Lisp value,
and that value (or one derived from it arithmetically) is then
passed to num_fast. The problem is that c_num succeeds on
integers outside of the fixnum range. Some bignum values
convert to a cnum successfully. Thus either num has to be used
instead of num_fast, or else the original c_num attempt must
be replaced with something that will fail if the original
value isn't a fixnum. (In the latter case, any arithmetic on
the fixnum cannot produce value outside of that range).
* buf.c (buf_put_bytes): The size argument here is not
guaranteed to be in fixnum range: use num.
* combi.c (perm_init_common): Throw if the sequence length
isn't a fixnum. Thus the num_fast in perm_while_fun is
correct, since the ci value is bounded by k, which is bounded
by n.
* hash.c (hash_grow): Remove dubious assertion which aborts
the run-time if the hash table doubling overflows. Simply
don't allow the modulus to grow beyond NUM_MAX. If doubling
it makes it larger than NUM_MAX, then just don't grow the
table. We need the modulus to be in fixnum range, so that
uses of num_fast on the modulus value elsewhere are correct.
(group_by, group_reduce): Use c_fixnum rather than c_num to
extract a value that is later assumed to be a fixnum.
* lib.c (c_fixnum): New function.
(nreverse, reverse, remove_if, less, window_map_list,
sort_vec, unique): Use c_fixnum rather than c_num to extract a
value that is later assumed to be a fixnum.
(string_extend): Use c_fixnum rather than c_num to extract a
value that is later assumed to be a fixnum. Cap the string
allocation size to fixnum range rather than INT_PTR_MAX.
(cmp_str): The wcscmp function could return values outside
of the fixnum range, so we must use num, not num_fast.
* lib.h (c_fixnum): Declared.
|
| |
|
|
|
|
|
| |
* buf.c (buf_grow): When size is zero and len is nonzero, the
loop doesn't terminate. Replace silly loop with
straightforward calculation: grow buffer by 25%, capped at
INT_PTR_MAX, or grow to the length, whichever is larger.

Old style casts have crept into the code base.
* buf.c (make_buf, buf_grow, buf_get_i8, buf_get_u8): Replace
old style cast with macro.
* ffi.c (align_sw_get, align_sw_put, ffi_be_i32_get,
ffi_be_u32_get, ffi_le_i32_put, ffi_le_i32_get,
ffi_le_u32_get, ffi_be_i64_put, ffi_be_i64_get,
ffi_be_u64_get, ffi_le_i64_put, ffi_le_i64_get,
ffi_le_u64_get, ffi_sbit_put, ffi_sbit_get,
ffi_init_extra_types): Likewise.
* hash.c (hash_buf): Likewise.
* itypes.c (c_i32, c_i64, c_u64): Likewise.
* stream.c (stdio_put_buf, stdio_fill_buf): Likewise.
|
| |
|
|
| |
* buf.c, ffi.c: Must include <stdarg.h> for va_list.
|
| |
|
|
|
|
|
| |
* buf.c (buf_put_bytes): We must extend the buffer based
on looking at the end position of the data transfer,
not the start position, so the buffer is large enough to
old the entire transfer.
|
| |
|
|
|
|
|
| |
* buf.c (buf_shrink): If a buffer has zero length,
don't shrink the allocation size all the way down to
zero, because that value indicates a non-resizeable
buffer.

Backing out of the scheme of (ptr buf) passing the
address of the internal pointer within buf objects.
Also giving buf in handlers, to prevent the fallback
on get.
* buf.c (buf_addr_of): Function removed.
* buf.h (buf_addr_of): Declaration removed.
* ffi.c (ffi_buf_in, ffi_buf_d_in): New functions.
(ffi_buf_alloc): Function removed.
(ffi_type_compile, ffi_init_types): Remove specialty alloc and
free functions from buffers, so the regular fixed allocator is
used. Give buffers the new in functions.
|
| |
|
|
|
|
| |
* buf.c (make_duplicate_buf): A duplicated buf is dynamic,
so the size must not be nil, which indicates a static or
borrowed one. Set the size properly, so finalize will free it.

The buf FFI type's alloc virtual should return a pointer to
the buffer's pointer, not the buffer itself.
What's currently going on is something silly, whereby
the pointer to the buffer is stored into the buffer
itself.
* buf.c (buf_addr_of): New function.
* buf.c (buf_addr_of): Declared.
* ffi.c (ffi_buf_alloc): Use buf_addr_of instead of buf_get.

* buf.c (make_duplicate_buf, buf_get, buf_fill): New
functions.
* buf.h (make_duplicate_buf, buf_get, buf_fill): Declared.
* ffi.c (struct txr_ffi_type): New member, nelem.
Keeps track of number of elements, for types that are
FFI pointers. This lets us support the get method so that
a buf can be a C function return value, if its size is
declared in our FFI type system.
(ffi_buf_put, ffi_buf_get, ffi_buf_fill): New functions.
(ffi_type_compile): Handle two new cases of syntax for
buffers: (buf <size>) and buf.

* buf.c (buf_put_float, buf_put_cptr, buf_get_float,
buf_get_cptr, align_float, align_cptr, size_float, size_cptr):
New functions.
(buf_init): Registered intrinsics buf-put-float, buf-put-cptr,
buf-get-float, buf-get-cptr, align-float, align-cptr,
size-float, size_cptr.
* buf.h (buf_put_float, buf_put_cptr, buf_get_float,
buf_get_cptr, align_float, align_cptr, size_float, size_cptr):
Declared.

buf_get_char, buf_get_uchar, buf_get_short, buf_get_ushort,
buf_get_int, buf_get_uint, buf_get_long, buf_get_ulong,

* Makefile (OBJS): New objects itypes.o and buf.o.
* buf.c, buf.h: New files.
* itypes.c, itypes.h: New files.
* lib.c (obj_print_impl): Handle BUF via buf_print and
buf_pprint.
(init): Call itypes_init and buf_init.
* parser.h (end_of_buflit): Declared.
* parser.l (BUFLIT): New exclusive state.
(grammar): New rules for recognizing start of buffer
literal and its interior.
(end_of_buflit): New function.
* parser.y (HASH_B_QUOTE): New token.
(buflit, buflit_items, buflit_item): New nonterminals
and corresponding grammar rules.
(i_expr, n_expr): These symbols now generate a buflit;
a buffer literal is a kind of expression.
(yybadtoken): Handle HASH_B_QUOTE case.
