2024-08-03Fix missing type checks before specbindMattias Engdegård
This fixes bugs that crashed Emacs when the Lisp interpreter was fed bad code. * src/eval.c (FletX, Flet, internal_lisp_condition_case) (funcall_lambda): Hoist symbol-with-pos elimination and type checks to a dominating position for efficiency. This also plugs at least two typing holes. (Mea culpa.) * test/src/eval-tests.el (eval-bad-specbind): New regression test.
2024-02-19* test/src/eval-tests.el (eval-tests/default-value): Add new test case.Ihor Radchenko
Bug#66117
2024-01-04(signal_or_quit): Preserve error object identityStefan Monnier
Make sure we build the (ERROR-SYMBOL . ERROR-DATA) object only once when signaling an error, so that its `eq` identity can be used. It also gets us a tiny bit closer to having real "error objects" like in most other current programming languages. * src/eval.c (maybe_call_debugger): Change arglist to receive the error object instead of receiving the signal and the data separately. (signal_or_quit): Build the error object right at the beginning so it stays `eq` to itself. Rename the `keyboard_quit` arg to `continuable` so say what it does rather than what it's used for. (signal_quit_p): Change arg to be the error object rather than just the error-symbol. * src/keyboard.c (cmd_error_internal, menu_item_eval_property_1): Adjust calls to `signal_quit_p` accordingly. * test/src/eval-tests.el (eval-tests--error-id): New test.
2024-01-04New special form `handler-bind`Stefan Monnier
AFAIK, this provides the same semantics as Common Lisp's `handler-bind`, modulo the differences about how error objects and conditions are represented. * lisp/subr.el (handler-bind): New macro. * src/eval.c (pop_handler): New function. (Fhandler_Bind_1): New function. (signal_or_quit): Handle new handlertypes `HANDLER` and `SKIP_CONDITIONS`. (find_handler_clause): Simplify. (syms_of_eval): Defsubr `Fhandler_bind_1`. * doc/lispref/control.texi (Handling Errors): Add `handler-bind`. * test/src/eval-tests.el (eval-tests--handler-bind): New test. * lisp/emacs-lisp/lisp-mode.el (lisp-font-lock-keywords): Move 'handler-bind' from CL-only to generic Lisp. (handler-bind): Remove indentation setting, it now lives in the macro definition.

2023-04-14Disallow creation of circular variable alias chainsMattias Engdegård
Make `defvaralias` signal an error upon attempts to create variable alias cycles. This detects errors earlier and makes the alias traversal during execution simpler and faster since no cycle detection is needed elsewhere. Now variable and function aliases are handled identically in these respects. * src/lisp.h (indirect_variable): Remove declaration. * src/data.c (indirect_variable): Remove. (Findirect_variable): Update doc string. Simplify alias resolution. (Fboundp, find_symbol_value, set_internal, default_value) (set_default_internal, Fmake_variable_buffer_local) (Fmake_local_variable, Fkill_local_variable, Flocal_variable_p) (Flocal_variable_if_set_p, Fvariable_binding_locus): * src/buffer.c (buffer_local_value): * src/eval.c (specbind): Simplify variable alias resolution. (Fdefvaralias): Update doc string. Check for cycles. * doc/lispref/variables.texi (Variable Aliases): Mention that `defvaralias` can signal `cyclic-variable-indirection` but `indirect-variable` cannot. * etc/NEWS: Announce the change. * test/src/eval-tests.el (eval-tests-defvaralias): New test.
2023-04-02src/eval.c: Fix bug#62419Stefan Monnier
Yup, almost 40 years after ELisp first combined them, buffer-local and let bindings still don't work quite right :-( The "automatically buffer-local if set" semantics should follow the principle that it becomes buffer-local iff the var's current binding refers to the top-level/global/non-let binding. * src/eval.c (let_shadows_buffer_binding_p): Disregard non-global let-bindings. * test/src/eval-tests.el (eval-test--bug62419): New test.

2022-09-23Remove max-specpdl-size overrun testMattias Engdegård
* test/src/eval-tests.el (eval-tests--exceed-specbind-limit) (eval-exceed-specbind-with-signal-hook): Remove test that is no longer useful, since there is no longer any specpdl limit to overrun. (The test still passed but vacuously so, by hitting the max-lisp-eval-depth limit instead.) This silences an obsoletion warning.
2022-05-30Fix atimer setting and overdue expiration (bug#55628)Mattias Engdegård
* src/atimer.c (set_alarm): If the atimer has already expired, signal it right away instead of postponing it further. Previously this could occur repeatedly, blocking atimers indefinitely. Also only use `alarm` as fallback if `setitimer` is unavailable, not both at the same time (which makes no sense, and they both typically use the same mechanism behind the curtains). * test/src/eval-tests.el (eval-tests/funcall-with-delayed-message): New test, verifying proper functioning of funcall-with-delayed-message which also serves as test for this bug (which also caused debug-timer-check to fail, but that test is only run when Emacs is built with enable-checking).

2018-03-25Allow `&rest' or `&optional' without following variable (Bug#29165)Noam Postavsky
This is sometimes convenient when writing macros, so that the empty variable case doesn't need to be handled specially.

2018-02-16Avoid memory corruption with specpdl overflow + edebug (Bug#30481)Noam Postavsky
If grow_specpdl fails due to outgrowing max_specpdl_size, it will signal an error *before* growing the specpdl array. Therefore, when handling the signal, specpdl_ptr points past the end of the specpdl array and any further use of of specpdl before unwinding (e.g., if edebug binds signal-hook-function) will cause memory corruption. * src/eval.c (signal_or_quit): Don't call `signal-hook-function' if the specpdl_ptr is already past the end of the specpdl array. * test/src/eval-tests.el (eval-tests--exceed-specbind-limit) (eval-exceed-specbind-with-signal-hook): New test & helper function.

2017-09-13Prefer HTTPS to FTP and HTTP in documentationPaul Eggert
Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.
2017-08-06Fix some crashes on self-modifying Elisp codePaul Eggert
Prompted by a problem report by Alex in: http://lists.gnu.org/archive/html/emacs-devel/2017-08/msg00143.html * 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 .

2017-04-22Don't require bytecomp for running ert testsNoam Postavsky
"Fix ert-tests when running compiled" 2016-12-06 accidentally introduced a dependency on `bytecomp' into `ert'. As mentioned in "Avoid ert test failures" 2017-04-18, the accidental dependency of ert on bytecomp was masked by loading other libraries until recently. * lisp/emacs-lisp/ert.el (ert--expand-should-1): Only use `byte-compile-macro-environment' if it's bound. * test/src/eval-tests.el: Add defvar for dynamic variable `byte-compile-debug'.
2017-01-19Check that variable lists are actually listsPhilipp Stephani
'let' and 'let*' document that their first argument has to be a list, but don't check for that; instead, they allow (and silently ignore) other types. Introduce an explicit type check. * src/eval.c (Flet, FletX): Check that the variable list is indeed a list. * test/src/eval-tests.el: Add unit tests.
