      Do not munge contents of local symbolic links · e8001d4c
      Paul Eggert authored
      This lets Emacs deal with arbitrary local symlinks without
      mishandling their contents (Bug#28156).  For example,
      (progn (shell-command "ln -fs '~' 'x'") (rename-file "x" "/tmp/x"))
      now consistently creates a symbolic link from '/tmp/x' to '~'.
      Formerly, it did that only if the working directory was on the
      same filesystem as /tmp; otherwise, it expanded the '~' to
      the user's home directory.
      * lisp/dired.el (dired-get-filename): Use files--name-absolute-system-p
      instead of rolling our own code.
      * lisp/files.el (files--name-absolute-system-p): New function.
      (file-truename, file-chase-links): Use it to avoid mishandling
      symlink contents that begin with ~.
      (copy-directory, move-file-to-trash):
      Use concat rather than expand-file-name, to avoid mishandling
      symlink contents that begin with ~.
      * src/fileio.c (Fmake_symbolic_link): Do not expand leading "~" in the
      target unless interactive.  Strip leading "/:" if interactive.
      (emacs_readlinkat): Do not prepend "/:" to the link target if
      it starts with "/" and contains ":" before NUL.
      * test/src/fileio-tests.el (try-link): Rename from try-char,
      and accept a string instead of a char.  All uses changed.
      (fileio-tests--symlink-failure): Also test leading ~, and "/:",
      to test the new behavior.

      Fix some crashes on self-modifying Elisp code · 93511e94
      Paul Eggert authored
      Prompted by a problem report by Alex in:
      * src/eval.c (For, Fprogn, Fsetq, FletX, eval_sub):
      Compute XCDR (x) near XCAR (x); although this doesn't fix any bugs,
      it is likely to run a bit faster with typical hardware caches.
      (Fif): Use Fcdr instead of XCDR, to avoid crashing on
      self-modifying S-expressions.
      (Fsetq, Flet, eval_sub): Count the number of arguments as we go
      instead of trusting an Flength prepass, to avoid problems when the
      code is self-modifying.
      (Fquote, Ffunction, Fdefvar, Fdefconst): Prefer !NILP to CONSP
      where either will do.  This is mostly to document the fact that
      the value must be a proper list.  It's also a tiny bit faster on
      typical machines nowadays.
      (Fdefconst, FletX): Prefer XCAR+XCDR to Fcar+Fcdr when either will do.
      (eval_sub): Check that the args are a list as opposed to some
      other object that has a length. This prevents e.g. (if . "string")
      from making Emacs dump core in some cases.

      Fix core dump in substitute-object-in-subtree · 083940a9
      Paul Eggert authored
      Without this fix, (substitute-object-in-subtree #0=(#0# 'a) 'a)
      would dump core, since the C code would recurse indefinitely through
      the infinite structure.  This patch adds an argument to the function,
      and renames it to lread--substitute-object-in-subtree as the function
      is not general-purpose and should not be relied on by outside code.
      See Bug#23660.
      * src/intervals.c (traverse_intervals_noorder): ARG is now void *,
      not Lisp_Object, so that callers need not cons unnecessarily.
      All callers changed.  Also, remove related #if-0 code that was
      “temporary” in the early 1990s and has not been compilable for
      some time.
      * src/lread.c (struct subst): New type, for substitution closure data.
      (seen_list): Remove this static var, as this info is now part of
      struct subst.  All uses removed.
      (Flread__substitute_object_in_subtree): Rename from
      Fsubstitute_object_in_subtree, and give it a 3rd arg so that it
      doesn’t dump core when called from the top level with an
      already-cyclic structure.  All callers changed.
      (SUBSTITUTE): Remove.  All callers expanded and then simplified.
      (substitute_object_recurse): Take a single argument SUBST rather
      than a pair OBJECT and PLACEHOLDER, so that its address can be
      passed around as part of a closure; this avoids the need for an
      AUTO_CONS call.  All callers changed.  If the COMPLETED component
      is t, treat every subobject as potentially circular.
      (substitute_in_interval): Take a struct subst * rather than a
      Lisp_Object, for the closure data.  All callers changed.
      * test/src/lread-tests.el (lread-lread--substitute-object-in-subtree):
      New test, to check that the core dump does not reoccur.

      Module assertions: check for garbage collections · b7dab24b
      Philipp Stephani authored
      It's technically possible to write a user pointer finalizer that calls
      into Emacs module functions.  This would be disastrous because it
      would allow arbitrary Lisp code to run during garbage collection.
      Therefore extend the module assertions to check for this case.

      garbage collection is in progress.

      Philipp Stephani authored
      Add a new command-line option '-module-assertions' that users can

      are invalid, so disable them by default.

      Reimplement module functions · 31fded03
      Philipp Stephani authored
      Instead of a lambda, create a new type containing all data required to
      call the function, and support it in the evaluator.  Because this type
      now also needs to store the function documentation, it is too big for
      Lisp_Misc; use a pseudovector instead.  That also has the nice benefit
      that we don't have to add special support to the garbage collector.
      Since the new type is user-visible, give it a predicate.
      Now we can easily support 'help-function-args' and 'func-arity'; add
      unit tests for these.
      * src/lisp.h (allocate_module_function, MODULE_FUNCTIONP)
      (XMODULE_FUNCTION): New pseudovector type 'module function'.
      * src/eval.c (FUNCTIONP): Also treat module functions as functions.
      (funcall_lambda, Ffuncall, eval_sub): Add support for calling module
      (Ffunc_arity): Add support for detecting the arity of module
      * src/emacs-module.c (module_make_function): Adapt to new structure.
      Return module function object directly instead of wrapping it in a
      lambda; remove FIXME.
      (funcall_module): New function to call module functions.  Replaces
      `internal--module-call' and is called directly from eval.c.
      (syms_of_module): Remove internal helper function, which is no longer
      (module_function_arity): New helper function.
      * src/data.c (Ftype_of): Adapt to new implementation.
      (Fmodule_function_p, syms_of_data): New user-visible function.  Now
      that module functions are first-class objects, they deserve a
      predicate.  Define it even if not compiled with --enable-modules so
      that Lisp code doesn't have to check for the function's existence.
      * src/doc.c (Fdocumentation): Support module functions.
      * src/print.c (print_object): Adapt to new implementation.
      * src/alloc.c (mark_object): Specialized garbage collector support is
      no longer needed.
      * lisp/help.el (help-function-arglist): Support module functions.
      While there, simplify the arity calculation by using `func-arity',
      which does the right thing for all kinds of functions.
      * test/data/emacs-module/mod-test.c: Amend docstring so we can test
      the argument list.
      * test/src/emacs-module-tests.el (mod-test-sum-docstring): Adapt to

      is gone, the backtrace has changed and no longer leaks the
      (module--func-arity): New test for `func-arity'.
