When TXR executes a top-level program, such that it will
exit when the last form in that program terminates,
it simulates a load. There is a block named load visible,
and the program can evaluate a (return-from load <expr>).
The value of that <expr> is thrown away, and the
termination status is always unsuccessful.
In this patch, (return-from load <expr>) is made to work
such that the value of <expr> will determine the exit
status, according to the same interpretation that
(exit <expr>) would give to the value.
* sysif.[ch] (exit_wrap): Static function becomes external.
* txr.c (txr_main): In the cases where we execute a file
and return from main, we now call exit_wrap instead.
The termination status is not simply based on whether
the file was successfully read, but takes into account the
load block.
* tests/019/load-ret/{script.tl,bad.tl}: New files.
* tests/019/load-ret/load-ret.tl: New tests.

link which resolves the source object if it is a symlink.
* configure: test for linkat.
* sysif.c (link_wrap_common): New static function, used
by both link_wrap and rlink_wrap.
(link_wrap): Now a one-liner which calls link_wrap_common.

It has been reported by user cielesti that some of our
crypt tests fail on the Musl library.
Musl has some additional agorithms so it yields
a meaningful hash for a "$0$" salt, as well as for "$9$".
Musl uses "*" and "x" as error tokens rather than "*0"
and "*1". We need to change how we detect error tokens.
* sysif.c (crypt_wrap): Detect error tokens only by their
length: if a string emerges from crypt or crypt_r, whose
length is less than 13, it's an error token.
* tests/018/crypt.tl: Drop the tests that require :error
for salts "$0$" and "$9$", replacing them with a test
for a salt that is almost certainly invalid in all C libraries
on Linux.
* txr.1: Document that crypt throws an error exception and
under what circumstances (when the C library function does
what).

Some OS distros have switched to a library called libxcrypt,
which, instead of returning null on failure, like the Glibc
crypt, returns a valid "failure token" string starting with
a * character, which is guaranteed to be different from the
salt argument.
We should check for this so that we handle errors uniformly.
Users are reporting failing crypt tests that are coming
up with "*0" instead of throwing an exception.
* sysif.c (crypt_wrap): Only accept a non-null result if
it isn't one of the two strings "*0" and "*1".
|
| |
|
|
|
|
|
|
|
| |
* sysif.c (sysif_init): The passwd symbol is used by both the
passwd and group structure, so we need to initialize it if
either HAVE_PWUID or HAVE_GRGID is set. Certain Android SDK
levels have getgrgid but not getpwuid, so it's possible to end
up with HAVE_GRGID but not HAVE_PWUID, in which case passwd_s
ends up nil, blowing up the make_struct_type call.

* sysif.c (crypt_wrap): Don't call free(cd) on platforms
where we don't have crypt_r and have not defined the
cd variable.
* test/018/crypt.tl: Move the (crypt "a" "b") test case
to be GNU/Linux-only. On Solaris, it yields a valid-looking
hash instead of failing. That hash will not validate the
password though; i.e. (crypt "a" (crypt "a" "b")) is not
equal to (crypt "a" "b").
|
| |
|
|
|
|
| |
* sysif.c (crypt_wrap): Dynamically allocate struct crypt_data
instead, because it's over 128K wide, resulting in a huge
stack frame size.

The validate_salt function was introduced in commit
c3a0ceb2cea1a9d43f2baf5a2e63d0d712c8df19, February 2020.
I cannot reproduce the internal crash in crypt which
it alleges, and I neglected to mention the bad inputs
in the commit or add tests. I'm not able to reproduce
the alleged behavior in spite of trying all sorts of bad
inputs; and looking at the crypt source in glibc, I
don't see any obvious problem.
And so, on this Halowe'en, we exorcise the ghost
that has been haunting the crypt.
* sysif.c (salt_char_p, validate_salt): Static functions
removed.
(crypt_wrap): Don't call validate_salt, and so cwsalt
need not be tested for null.
* tests/018/crypt.tl: New file.
* txr.1: Mention that crypt_r is used if available, which
avoids static storage.

* args.h (args_decl_list): This macro now handles only
constant values of N. It declares an anonyous container
struct type which juxtaposes the struc args header
with exactly N values. This is simply defined as a local
variable without alloca.
(args_decl_constsize): Like args_decl, but requiring a
constant N; implemented via args_decl_list.
(args_decl_list_dyn): New name for the old args_decl_list
which calls alloca. No places in the code depend on this
at all, except the definition of args_decl.
(args_decl): Retargeted to args_decl_list_dyn.
There is some inconsistency in the macro naming in that
args_decl_constsize depends on args_decl_list, and
args_decl depends on arg_decl_list_dyn. This was done
to minimize diffs. Most direct uses of args_decl_list
have a constant size, but a large number of args_decl
uses do not have a constant size.
* eval.c (op_catch): Use args_decl_constsize.
* ffi.c (ffi_struct_in, ffi_struct_get, union_out):
Likewise.
* ftw.c (ftw_callback): Likewise.
* lib.c (funcall, funcall1, funcall2, funcall3,
funcall4, uniq, relate): Likewise.

It is against TXR coding conventions to use the C cast
notation. The usage creeps into the code. To find instances of
this, we must compile using GNU g++, and add -Wold-style-cast
via EXTRA_FLAGS.
* eval.c (prof_call): Use macro instead of cast.
* ffi.c (pad_retval, ffi_varray_alloc, make_ffi_type_union,
carray_dup, carray_replace, uint_carray, int_carray,
put_carray, fill_carray): Likewise.

* lib.c (cyr, chk_xalloc, spilt_str_keep, vector,
cobj_register): Likewise.
* linenoise.c (record_undo): Likewise. Also, drop one
superfluous cast: wstrdup_fn returns wchar_t *.
(flash, edit_insert, edit_insert_str): Use macro instead of cast.
* mpi/mpi.c (s_mp_ispow2d): Likewise.
* parser.c (lino_getch): Likewise.
* rand.c (make_random_state, random_buf): Likewise.
* stream.c (generic_get_line, do_parse_mode): Likewise.

* lib.h (num_ex): New macro. Uses unum if the argument is out
of range for the signed type. Thus we can use this with
unsigned constants that would wrap negative if passed to num.
This is useful if some type in a system header file might be
signed or unsigned.
* sysif.c (sysif_init): Use num_ex for the RLIM_* constants.
I'm observing values of -1 which should really be large,
positive values in the rlim_t type, that being unsigned.

Now that we fixed the regression in detecting whether to use
-D_FILE_OFFSET_BITS=64, this has unmasked an issue in newer
code. In sysif.c, the RLIM_INFINITY, and related constants,
are being passed to num_fast: but they are 64 bit unsigned
constants under the large file offset, which don't fit into a
cnum or unum on a 32 bit system.
* configure: When we detect large file offset, we deposit
the tell-tale configuration constant CONFIG_LARGE_FILE_OFFSET
into config.h.
* sysif.c (sysif_init): Under CONFIG_LARGE_FILE_OFFSET,
treat the RLIM_ constants using bignum_dbl_uipt.

The use of -ansi doesn't by itself diagnose instances of some
constructs we don't want in the project, like mixed
declarations and statements.
* configure (diag_flags): Add -Werror=declaration-after-statement.
This is C only, so filter it out for C++.
Also add -Werror=vla.
* HACKING: Update inaccurate statements about what dialect we
are using. TXR isn't pure C90: some GCC extensions are used.
We even use long long if the configure script detects it as
working, and some C99 library features.
* buf.c (replace_buf, buf_list): Fix by reordering.
* eval.c (op_dohash, op_load_time_lit): Fix by reordering.
* ffi.c (ffi_simple_release): Fix by reordering.
(align_sw_get): Fix empty macro to expand to dummy declaration
so a semicolon after it isn't interpreted as a statement.
On platforms with alignment, remove a semicolon from the macro
so that it requires one.
(ffi_i8_put, ffi_u8_put): Fix by reordering.
* gc.c (gc_init): Fix with extra braces.
* hash.c (hash_init): Fix by reordering.
* lib.c (list_collect_revappend, sub_iter, replace_str,
replace_vec, mapcar_listout, mappend, mapdo, window_map_list,
subst): Fix by reordering.
(gensym, find, rfind, pos, rpos, in, search_common): Fix by
renaming optional argument and using declaration instead of
assignment.
* linenoise/linenoise.c (edit_in_editor): Fix by reordering.
* parser.c (is_balanced_line): Fix by reordering.
* regex.c (nfa_count_one, print_rec): Fix by reordering.
* signal.c (sig_mask): Fix by reordering.

* unwind.h (uw_block_beg): New macro which doesn't define
RESULTVAR but expects it to refers to an existing one.
(uw_block_begin): Replace do while (0) with enum trick
so that we have a declaration that requires a semicolon,
rather than a statement, allowing declarations to follow.
(uw_match_env_begin): Now opens a scope and features the
same enum trick as in uw_block_begin.
This fixes a declaration-follows-statement issue in
the v_output function in match.c.

(exec_wrap): If *child-env* is other than t, then save the
environment in a list, and install the specified environment
before calling execvp. If that function returns, restore the

Using this new function together with env, it's now possible
to save the set of environment variables, clobber it to a
specified set (possibly empty) and then restore it.
Useful for improved security in running child processes.

Basic idea: when we throw an exception that pertains to a
system error which has an errno code, we can stick the errno
into the memory area of the character string, into the wchar_t
that immediately follows the null terminator. We can do this
because strings track their actual allocation size.
A pair of setter/getter functions to set and retrieve this
value are provided, and all functions in the code which can
set such a code are updated to do so, simply by calling the
newly added uw_ethrowf that drop-in replaces for uw_throwf.

This is a big commit motivated by the need to clean up the
situation with built-in type symbols, COBJ objects and
structs.
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.

This function back-fills the missing d-type information in a
dirent on platforms that don't provide d_type in the native
dirent.
* sysif.c (DT_FIFO, DT_CHR, DT_DIR, DT_BLK, DT_REG, DT_LNK,
DT_SOCK): Define all these preprocessor symbols to their Linux
values on platforms where DT_DIR is not defined.
(DT_UNKNOWN): Make sure this symbol is #undef-d if DT_DIR
is not defined, so the corresponding dt-unknown variable does
not exist.
(dirstat): New static function.
(sysif_init): Register dirstat intrinsic. Register dt-fifo and
the rest unconditionally now. Changing their order to
increasing numeric.
* txr.1: Documented.

* sysif.c (opendir_free): Since d->dir may now be null, avoid
calling closedir on it in that situation. Also, set d->dir to
null after closedir.
(closedir_wrap): New static function.
(readdir_wrap): If the d->dir is null, safely treat that as a
directory entry not being available; do not pass a null DIR
pointer to readdir.
(sysif_init): Register intrinsic function closedir.
* txr.1: Documented, plus spelling error fix under readdir.
|
| |
|
|
|
|
| |
* sysif.c (opendir_wrap): Store path into d->path after
allocating the cobj, because d->path may be the only reference
to that object, and the cobj call may trigger gc.

The c_num and c_unum functions now take a self argument for
identifying the calling function. 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.
