* sysif.c (sysif_init): Fix misspelled FNM_EXTMATCH in #ifdef
causing registration of fnm-extmatch being excluded.

|

* sysif.c (validate_salt): Take const wchar_t * argument
instead of val. Set errno and return null pointer instead of
throwing, so we don't have two places that throw an exception
related to crypt.
(crypt_wrap): Put exception at the end. Return hash only if
validate_salt returns a non-null pointer and so does crypt.
In all other cases, reach exception call.

The crypt function on glibc, and maybe other platforms, simply
crashes when given a perfectly valid salt string that contains
invalid salt syntax. This is nasty; we want TXR Lisp
library functions to be robust; bringing down the image is not
acceptable.
Also, crypt may return a null pointer. glibc's crypt does
this in certain situations, like when the "2a" (Blowfish)
algorithm is specified when not available. We are not checking
for this null return, in which case the ensuing crash is our
fault.
* sysif.c (salt_char_p, validate_salt): New functions.
(crypt_wrap): Validate the salt via validate_salt.
Check the return value from crypt/crypt_r; if null,
then throw an exception that incorporates the errno
information.

This is Coreutils chmod behavior.
* sysif.c (chmod_wrap): Sample cmode into oldm at the start of
every assigment before punching the masked hole into cmode.

Within the same clause, permissions given by ugo must refer to
the unaltered permissions, before the target bits were masked
out, otherwise self-assignment like o=o just clears the
permissions. The other self-referential perm is X: it checks
for existing x permissions. That works with the current
value.
* sysif.c (chmod_wrap): Keep the old permissions in a new loop
variable called oldm. The u, g and o perms refer to oldm
rather than to the updated value in cmode. When we hit a
comma, we update oldm to the current value. The code for
this is now in one place with a goto.
* tests/018/chmod.tl: New test case that fails in the
absence of this fix. Test cases confirming that X
refers to the current permissions.

|

|
|
|
|
|

* sysif.c (chmod_wrap): The chm_comma state is transitioned to
after seeing a right hand side u, g or o. These do not combine
with other letters, so ch_comma expects a comma after which a
new permission clause we start,. Therefore the srcm and who
variables must be rest. It's also a good idea to continue the
loop.
* tests/018/chmod.tl: New test case which exposed
the above issue.

* sysif.c (chmod_wrap): Again, related to the = operator, we
must not punch a hole in the suid and sgid bits for all
non-directory objects. This was based on a misinterpretation
of some coreutils documentation, and doesn't match the
actual behavior. Rather, if the owner is a target (including
implicitly) then we mask out suid; and if the group owner is a
targe, then we mask out sgid. Thus when we are doing a
permission set not targetting the owner we don't touch suid,
and similarly for the group owner and setgid.
* tests/018/chmod.tl: Failed test diagnostics now
identify which mode string was used.
Some existing tests involving the suid/sgid bits
have to be revised because this commit reflects
a correction in the requirements. One new test is added.

* sysif.c (chmod_wrap): When processing set (=), only punch a
hole in the target permission area once per clause, so as not
to clobber previously set modes. We do this by checking for
the chm_perm state. Whenever '=' is processed, the state machine
enters into that state; when any permission letter is then
processed, it transitions out of that state. This gets the
"u=rwsx" test to pass.
* tests/018/chmod.tl: New tests.
|
|
|
|
|
|
|
|
|
| |
* sysif.c (chmod_wrap): The umask logic is not activating
after the first iteration through the loop, because when who
is zero, we clobber it by adding the bits for u, g, and o.
Then on subsequent iterations, who is no longer zero.
Instead, let us leave the value of who alone, and in
all the relevant places, check for it being zero.
|
|
|
|
|
| |
* sysif.c (chmod_wrap): Clear the sticky bit from the right
variable: cmode rather than bits.
|
|
|
|
|
|
| |
* sysif.c (chmod_wrap): The uw_throw expression contains an
otal format specifier ~o which requires an integer argument;
but the mode can be a string now. Split into two cases.

We can get rid of fstat_wrap entirely and make
the lstat and fstat function bindings point to the same
function.
* parser.c (load_rcfile): Call stat_wrap instead of
fstat_wrap.
* sysif.c (stat_wrap): Static function becomes extern. Useless
forward declaration removed.
(fstat_wrap): Static function removed.
(sysif_init): Bind fstat and lstat to the same function
object.
* sysif.h (fstat_wrap): Declaration removed.
(stat_wrap): Declaration added.
|
|
|
|
|
|
|
|
|
|
|
|
| |
* sysif.c (get_fd): Move this function higher in the file to
avoid forward declarations. The do_fstatt code being moved into
do_stat needs to call it.
(do_stat): Provide stat and fstat functionality in one
function.
(do_fstat): Static function removed.
(fstat_wrap): Call do_stat instead of do_fstat.
* txr.1: Updated.

The chmod function can now take a string, which uses the same
conventions as the symbolic mode argument of the chmod utility.
* sysif.c (CHM_O, CHM_G, CHM_U): New preprocessor symbols.
(enum chm_state, enum chm_op): New enums.
(chmod_wrap): Allow argument to be a string, and in that case
interpret the chmod symbolic permission language.
* txr.1: Documented.

|
|
|
|
|
|
|
| |
* sysif.c (do_stat, do_lstat): Functions relocated before
mkdir_nothrow_exists.
(mkdir_nothrow_exists): In the EEXIST case, call stat on the
object. If it's not a directory or a symlink to a directory,
then do not suppress the error; propagate it to the caller,
where it will become an exception.
* txr.1: Specify the behavior of ensure-dir more precisely:
that it only supresses the existence error for directories
and directory symlinks.
|
|
|
|
|
|
|

* configure: detect mkfifo.
(sysif_init): Register mkfifo intrinsic.

Some functions in utf8.c have w_ prefixes. They are wide
character wrappers for functions that take multi-byte string
inputs.
The prefix is being inappropriately used in the names of a
few sysif functions that should be named _wrap.
* sysif.c (w_stat, w_lstat, w_fstat): Rename to do_stat,
do_lstat and do_fstat, respectively. These are callbacks
used with stat_impl.
(statp, statl, statf): Rename to stat_wrap, lstat_wrap and
fstat_wrap, following existing convention. Additionally,
stat_wrap becomes static since nothing outside this file
calls it.
(sysif_init): Follow renames of statp, statl and statf.
* sysif.h (statp): Declaration removed.
(statf): Renamed to fstat_wrap.
* parser.c (load_rcfile): Follow statf rename.
|
|

The sysif.h header breaks on some systems because it
references off_t, which requires <sys/types.h>. But the off_t
materials in this header are unnecessary; we can remove
them.
* sysif.c (off_t_num, num_off_t): Extern functions become static,
and are wrapped with #if HAVE_FSEEKO. These functions are
only called from sysif.c, only from code relying on fseeko.
* sysif.h (OFF_T_MAX, OFF_T_MIN): Macros not used anywhere are removed.
(off_t_num, num_off_t): Declarations removed.

We introduce the function c_time to convert a Lisp integer
to time_t, and num_time to do the reverse conversion.
The FFI type time-t already does this right.
(See registration of time-t in ffi_init_extra_types).
* hash.c (gen_hash_seed): The first value out of time_sec_usec
corresponds to a time_t value. We now convert this to C number
using c_time rather than c_num. Also, while we are touching
this code, the microseconds value can convert directly to
ucnum with c_unum.
* lib.c (time_sec_usec): Use num_time for seconds.
(time_string_local, time_string_utc, time_fields_local,
time_fields_utc, time_struct_local, time_struct_utc): Use c_time.
(make_time_impl, time_parse_utc): Use num_time instead of num.
* signal.h (getitimer_wrap, setitimer_wrap): Convert tv_sec
members of struct timeval using c_time and num_time.
* sysif.c (c_time, num_time): New functions.
(stat_to_struct): Convert st_atime, st_mtime and st_ctime
to Lisp using num_time instead of num.
* sysif.c (c_time, num_time): Declared.

* configure (have_sys_stat): New variable. Set to y when our
test detects <sys/stat.h>. New test added for the presence of
high resolution time stamps in struct stat. If we have these,
we #define HAVE_STAT_NSEC 1 in config.h.
* share/txr/stdlib/path-test.tl (path-newer): Compare
nanosecond parts of the modification time if the seconds are
equal, improving the resolution of the test.
* sysif.c (atime_nsec_s, mtime_nsec_s, ctime_nsec_s): New
symbol variables.
(stat_to_struct): If nanosecond resolution is available, set
the new nanosecond slots from the three tv_nsec fields in
struct stat. Otherwise, set the new slots to zero.
(sysif_init): Initialize the new symbol variables. Add the
three new slots to the stat struct.
* sysif.c (atime_nsec_s, mtime_nsec_s, ctime_nsec_s):
Declared.
* txr.1: Documented new atime-nsec, mtime-nsec and ctime-nsec
slots of stat structure. Added note to path-newer mentioning
high resolution support.

* configure: New test for crypt_r, depositing HAVE_CRYPT_R
preprocessor symbol in config.h.

(sysif_init): Register crypt intrinsic if we HAVE_CRYPT or if
we HAVE_CRYPT_R.

Several new more specific exception types are derived from
file-error and used. Error handlers can distinguish unexpected
non-existence, unexpected existence and permission errors
from each other and other errors.
* lib.c (path_not_found_s, path_exists_s, path_permission_s):
New symbol variables.
(obj_init): New variables initialized.
* lib.h (path_not_found_s, path_exists_s, path_permission_s):
Declared.
* parser.c (open_txr_file): Use new errno_to_file_error
function to convert errno to exception symbol.
* socket.c (open_sockfd): Likewise.
* stream.c (open_directory, open_file, open_fileno,
open_command, open_process, run, remove_path, rename_path):
Likewise, and process-error is used in open_process and run
instead of file-error for problems related to creating the
process.
* sysif.c (errno_to_file_error): New function.
(mkdir_wrap, ensure_dir, chdir_wrap, getcwd_wrap, mknod_wrap,
chmod_wrap, symlink_wrap, link_wrap, readlink_wrap, stat_impl,
umask_wrap, ): Use
errno_to_file_error to convert errno to exception symbol.
(exec_wrap): Use process-error instead of file-error.
* sysif.c (errno_to_file_error): Declared.
* unwind.c (uw_init): Register path-not-found, path-exists and
path-permission as subtypes of file-error.

* stream.c (stdio_seek): Handle new-style Boolean return from
stdio_fseek.
* sysif.c (stdio_fseek): Return an int indication that is 1
for success, 0 for failure. There was a mistaken assumption
here that fseeko returns the file offset, and the return value
in the fseek case was mistakenly harmonized, using a wasteful
call to stdio_ftell. The only call to this function relies
only on a Boolean success/fail indication.
* sysif.h (stdio_fseek): Declaration updated.
|
|
|
|
|
|
| |
* sysif.c (num_off_t): Remove #ifdef here and just use num_64
if off_t fits into 64 bits. Now this code compiles even if
HAVE_DOUBLE_INTPTR_T is missing.

|
|
|

* 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.
|
|
|
|
|
|
|
|
|
|
|
| |
* arith.c (bignum_dbl_ipt): Change internal function to
external linkage.
* arith.h (bignum_dbl_ipt): Conditionally declared.
* sysif.c (num_off_t): Use bignum_dbl_ipt instead of
open-coding exactly the same thing that bignum_dbl_ipt does.
Abort is changed to same internal_error as in off_t_num.
|
|
|
|
|
|
|
|
|
|
|
| |
* sysif.c (off_t_num): Retarget to just use c_i32 or c_i64
from ctypes.c, depending on which of these types is the same
width as off_t.
(stdio_fseek): Pass identifying "self" string to off_t_num.
Don't use off_t_num for fseek's offset argument which is of
type long; for that we can use c_long from ctypes.c.
* sysif.h (off_t_num): Declaration updated.

* mpi/mpi.h (mp_sign, mp_isneg, mp_used, mp_alloc, mp_digits,
mp_digit): New macros, based on renaming SIGN, ISNEG, USED,
ALLOC, DIGITS and DIGIT.
(mp_set_prec): Use mp_digits instead of DIGITS.
* mpi/mpi.c (SIGN, ISNEG, USED, ALLOC, DIGITS, DIGIT): Macros
defined here now, as local aliases for their namespaced
counterparts.
* arith.c (signum, floordiv): Replace ISNEG with mp_isneg.
* rand.c (random): Replace ISNEG with mp_isneg.
* sysif.c (off_t_num): Replace USED, DIGITS and ISNEG with
mp_used, mp_digits and mp_isneg.

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>.

The GNU C library is deprecating the practice of <sys/types.h>
defining the makedev, major and minor macros. A loud,
multi-line warning is issued for programs which include this
header and then use the macros. The new way is to rely on
the <sys/sysmacros.h> header instead. Of course, that might
not exist.
* configure (have_makedev): New variable. Upgrade the makedev
test to try it with <sys/sysmacros.h> first, then fall back
on <sys/types.h>. A new config macro HAVE_SYS_SYSMACROS_H
is created in config.h if sysmacros exists.
* sysif.c: If config.h defines HAVE_SYS_SYSMACROS_H to a
nonzero value, then include <sys/sysmacros.h>.

using getexecname, which requires us to prepend the current
directory name if the result is a relative path.

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.

* sysif.c (excec_wrap): Check that our nargs manipulation
doesn't exceed INT_MAX. Use chk_xalloc to allocate the
argument vector, providing an overflow check. Use self
variable in place function name embedded in literal.
(getgroups_wrap): Use chk_xalloc instead of chk_malloc,
so multiplication overflow is checked. Use self variable
in place function name embedded in literal.
(setgroups_wrap): Revamp existing overflow check. Use
ucnum for the size, check that it can convert to size_t
and back without loss of value, and use chk_xalloc
instead of chk_malloc.
