| * | Unbreak a fileio test on non-Mac OS X systemsGlenn Morris2017-12-201-1/+4
| | | | | | | | | | | | | | | | | | * test/src/fileio-tests.el (fileio-tests--symlink-failure): Don't use an undefined coding system. ; No need to merge to master, since breaking commit wasn't merged.
| * | Use utf-8-hfs-unix on macOS (Bug#29712)Alan Third2017-12-161-1/+2
| | | | | | | | | | | | | | | | | | | | | This is a quick fix for the Emacs 26 release. Do not merge to master. * test/src/fileio-tests.el (fileio-tests--symlink-failure): Override file-name-coding-system to utf-8-hfs-unix to prevent test failure.
* | | Allow JSON parser functions to return alistsPhilipp Stephani2017-12-191-7/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/json.c (Fjson_parse_string, Fjson_parse_buffer): Give these functions a keyword argument to specify the return type for JSON objects. (json_to_lisp): Convert objects to alists if requested. (json_parse_object_type): New helper function to parse keyword arguments. * test/src/json-tests.el (json-parse-string/object): Add a unit test. * doc/lispref/text.texi (Parsing JSON): Document new functionality.

| | | | | | | | | | | | | | | | | | | | | | Behaving like Common Lisp is less likely to lead to surprises, as it yields the same answers on 32- vs 64-bit machines. * doc/lispref/numbers.texi (Bitwise Operations): Document behavior on negative integers. * src/data.c (Flogcount): Behave like Common Lisp for negative arguments. * test/src/data-tests.el (data-tests-popcnt) (data-tests-logcount): Test negative args too.

* Expose viewing conditions in CAM02-UCS metricMark Oteiza2017-09-211-5/+32
| | | | | | | | | | | | | | | | Also add tests from the colorspacious library. Finally, catch an errant calculation, where degrees were not being converted to radians. * src/lcms.c (deg2rad, default_viewing_conditions): (parse_viewing_conditions): New functions. (lcms-cam02-ucs): Add comments pointing to references used. Expand the docstring and explain viewing conditions. JCh hue is given in degrees and needs to be converted to radians. (lcms-d65-xyz): Remove. No need to duplicate this in Lisp or make the API needlessly impure. * test/src/lcms-tests.el: Reword commentary. (lcms-rgb255->xyz): New function. (lcms-cri-cam02-ucs): Fix let-binding. (lcms-dE-cam02-ucs-silver): New test, assimilated from colorspacious.
* Fix 2 testsuite tests for MS-WindowsEli Zaretskii2017-09-201-1/+5
| | | | | | | | * test/lisp/ibuffer-tests.el (test-buffer-list): Don't try to create files with "*" in their names. * test/src/editfns-tests.el (format-time-string-with-zone): Adapt results to MS-Windows build. Reported by Fabrice Popineau <fabrice.popineau@gmail.com>.
* Adapt fileio-tests--symlink-failure to CygwinKen Brown2017-09-181-0/+2
| | | | | | * test/src/fileio-tests.el (fileio-tests--symlink-failure) [CYGWIN]: Skip the case of a symlink target starting with '\'; this is treated specially on Cygwin.
* Fix format-time-string %Z bug with negative tzPaul Eggert2017-09-171-0/+4
| | | | | | | * src/editfns.c (tzlookup): Fix sign error in %Z when a purely numeric zone is negative (Bug#28746). * test/src/editfns-tests.el (format-time-string-with-zone): Add test for this bug.
* Fix bug with min and max and NaNsPaul Eggert2017-09-171-1/+5
| | | | | | * src/data.c (minmax_driver): Fix bug with (min 0 NaN), which mistakenly yielded 0. Also, pacify GCC in a better way. * test/src/data-tests.el (data-tests-min): Test for the bug.

* Add lisp variable lcms-d65-xyzMark Oteiza2017-09-161-0/+19
| | | | | | | | | | This serves as the default optional argument for functions in this library. * src/lcms.c (lcms-d65-xyz): New variable. (lcms-cam02-ucs): Use it. Use better word in docstring. Fix bug color1 -> color2. * test/src/lcms-tests.el: Add some tests for lcms-cri-cam02-ucs. (lcms-colorspacious-d65): New variable.
* Add lcms-temp->white-point and initial testsMark Oteiza2017-09-151-0/+69
| | | | | * src/lcms.c (lcms-temp->white-point): New function. * test/src/lcms-tests.el: New file.
* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-1331-34/+34
| | | | | | | | | | | | | 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.
* Fix 'directory-file-name' on DOS_NT systems as wellEli Zaretskii2017-09-081-0/+30
| | | | | | | | | | * src/fileio.c (directory_file_name) [DOS_NT]: Fix the DOS_NT case to be consistent with last change. * test/src/fileio-tests.el (fileio-tests--odd-symlink-chars): Disable on MS-Windows. (fileio-tests--directory-file-name-dos-nt) (fileio-tests--file-name-as-directory-dos-nt): New tests.
* Fix bug: (directory-file-name "///") returned "//"Paul Eggert2017-09-071-0/+19
| | | | | | | * src/fileio.c (directory_file_name): For "///" and longer, return "/", not "//", as per POSIX. * test/src/fileio-tests.el (fileio-tests--directory-file-name) (fileio-tests--file-name-as-directory): New tests.
* Improve error messages for improper plists (Bug#27726)Philipp Stephani2017-09-021-0/+28
| | | | | | | | | | | | * src/fns.c (Fplist_put, Flax_plist_get, Flax_plist_put) (Fplist_member, syms_of_fns): Use ‘plistp’ as pseudo-predicate for improper plists instead of ‘listp.’ * test/src/fns-tests.el (plist-get/odd-number-of-elements) (lax-plist-get/odd-number-of-elements) (plist-put/odd-number-of-elements) (lax-plist-put/odd-number-of-elements) (plist-member/improper-list): Add unit tests.
* Do not munge contents of local symbolic linksPaul Eggert2017-08-261-11/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Change recent symlink tests to just test ASCIIPaul Eggert2017-08-191-4/+2
| | | | | | * test/src/fileio-tests.el (fileio-tests--symlink-failure): Be less ambitious about testing non-ASCII chars and encoding errors, as there are too many portability issues.
* Don’t adjust CRLF in file namesPaul Eggert2017-08-191-0/+49
| | | | | | | | | | | | | * doc/misc/gnus.texi (Non-ASCII Group Names): * etc/NEWS: * test/lisp/net/tramp-tests.el (tramp--test-utf8): Use utf-8-unix, not utf-8, for default-file-name-coding-system, so that CRLF in file names is left alone. * lisp/international/mule-cmds.el (set-default-coding-systems): Do not alter CRLF in file name coding systems. (prefer-coding-system): Ignore differences in CRLF processing when checking whether we used the user-specified file name coding system. * test/src/fileio-tests.el: New file.
* Fix crashing emacs-module tests on MS-WindowsEli Zaretskii2017-08-091-4/+12
| | | | | | | | | | | | * src/w32fns.c (syms_of_w32fns) <w32-disable-abort-dialog>: New variable. (emacs_abort): If w32-disable-abort-dialog is non-nil, abort right away, without displaying the Abort dialog, which waits for the user. * test/src/emacs-module-tests.el (module--test-assertion): Run the inferior Emacs with the w32 abort dialog disabled. Expect the status of the aborted Emacs sub-process to be 3 on MS-Windows and 2 on MS-DOS.
* Fix some crashes on self-modifying Elisp codePaul Eggert2017-08-061-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | 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 . "string") from making Emacs dump core in some cases. * test/src/eval-tests.el (eval-tests--if-dot-string) (eval-tests--let-with-circular-defs, eval-tests--mutating-cond): New tests.
* Fix a bug in 'generate-new-buffer-name'Eli Zaretskii2017-08-051-0/+5
| | | | | | | | | * src/buffer.c (Fgenerate_new_buffer_name): Test IGNORE for being nil before calling string-equal, since the latter will compare "nil and 'nil' as equal. (Bug#27966) * test/src/buffer-tests.el (test-generate-new-buffer-name-bug27966): New test.
* Signal error for symbol names with strange quotes (Bug#2967)Noam Postavsky2017-07-221-0/+17
| | | | | | | | * src/lread.c (read1): Signal an error when a symbol starts with a non-escaped quote-like character. * test/src/lread-tests.el (lread-tests--funny-quote-symbols): New test. * etc/NEWS: Announce change.
* Add an optional testfn parameter to assocNicolas Petton2017-07-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | * src/fns.c (assoc): New optional testfn parameter used for comparison when provided. * test/src/fns-tests.el (test-assoc-testfn): Add tests for the new 'testfn' parameter. * src/buffer.c: * src/coding.c: * src/dbusbind.c: * src/font.c: * src/fontset.c: * src/gfilenotify.c: * src/image.c: * src/keymap.c: * src/process.c: * src/w32fns.c: * src/w32font.c: * src/w32notify.c: * src/w32term.c: * src/xdisp.c: * src/xfont.c: Add a third argument to Fassoc calls. * etc/NEWS: * doc/lispref/lists.texi: Document the new 'testfn' parameter.
* Fix failing module tests on GNU/LinuxGlenn Morris2017-07-091-2/+2
| | | | | | | * test/src/emacs-module-tests.el (module--test-assertions--load-non-live-object) (module--test-assertions--call-emacs-from-gc): Avoid test failures due to backtraces.
* Fix core dump in substitute-object-in-subtreePaul Eggert2017-07-091-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 collectionsPhilipp Stephani2017-07-081-29/+58
| | | | | | | | | | | | | | | | | | | | 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. * src/emacs-module.c (module_assert_thread): Also check whether a garbage collection is in progress. * test/data/emacs-module/mod-test.c (invalid_finalizer) (Fmod_test_invalid_finalizer): New test module functions. (emacs_module_init): Register new test function. * test/src/emacs-module-tests.el (module--test-assertion) (module--with-temp-directory): New helper macros. (module--test-assertions--load-non-live-object): Rename existing unit test, use helper macros. (module--test-assertions--call-emacs-from-gc): New unit test.
* Add command to replace buffer contentsPhilipp Stephani2017-06-171-0/+31
| | | | | | | | | | | | | | | | | Add a new command 'replace-buffer-contents' that uses the Myers diff algorithm to non-destructively replace the accessible portion of the current buffer. The Myers algorithm is implemented in Gnulib. * src/editfns.c (Freplace_buffer_contents): New command. (set_bit, bit_is_set, buffer_chars_equal): New helper functions. (syms_of_editfns): Define new command. * test/src/editfns-tests.el (replace-buffer-contents-1) (replace-buffer-contents-2): New unit tests. * src/buffer.h (BUF_FETCH_CHAR_AS_MULTIBYTE): New helper macro. * admin/merge-gnulib (GNULIB_MODULES): Add diffseq.h and minmax.h.
* Add test for the fix in the parent commitDmitry Gutov2017-06-171-0/+22
| | | | | * test/src/undo-tests.el (undo-test-skip-invalidated-markers): New test, for the fix in the parent commit.
* Give a more informative failure in module assertion testGlenn Morris2017-06-121-5/+8
| | | | | * test/src/emacs-module-tests.el (module--test-assertions): Rephrase final check to give a more informative failure.
* Clean up after module assertion testsGlenn Morris2017-06-121-20/+24
| | | | | * test/src/emacs-module-tests.el (module--test-assertions): Use a temporary directory to contain any core dumps.
* Small improvement for module assertion testGlenn Morris2017-06-121-15/+15
| | | | | * test/src/emacs-module-tests.el (module--test-assertions): Don't rely on the precise form of an "Abort" message.
* Implement module assertions for usersPhilipp Stephani2017-06-121-3/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new command-line option '-module-assertions' that users can enable developing or debugging a module. If this option is present, Emacs performs additional checks to verify that modules fulfill their requirements. These checks are expensive and crash Emacs if modules are invalid, so disable them by default. This is a command-line option instead of an ordinary variable because changing it while Emacs is running would cause data structure imbalances. * src/emacs.c (main): New command line option '-module-assertions'. * src/emacs-module.c (module_assert_main_thread) (module_assert_runtime, module_assert_env, module_assert_value): New functions to assert module requirements. (syms_of_module): New uninterned variable 'module-runtimes'. (init_module_assertions, in_main_thread, module_abort): New helper functions. (initialize_environment): Initialize value list. If assertions are enabled, use a heap-allocated environment object. (finalize_environment): Add assertion that environment list is never empty. (finalize_runtime_unwind): Pop module runtime object stack. (value_to_lisp): Assert that the value is valid. (lisp_to_value): Record new value if assertions are enabled. (mark_modules): Mark allocated object list. (MODULE_FUNCTION_BEGIN_NO_CATCH) (module_non_local_exit_check, module_non_local_exit_clear) (module_non_local_exit_get, module_non_local_exit_signal) (module_non_local_exit_throw): Assert thread and environment. (module_get_environment): Assert thread and runtime. (module_make_function, module_funcall, module_intern) (module_funcall, module_make_integer, module_make_float) (module_make_string, module_make_user_ptr, module_vec_get) (funcall_module, Fmodule_load): Adapt callers. (module_make_global_ref): If assertions are enabled, use the global environment to store global values. (module_free_global_ref): Remove value from global value list. * test/Makefile.in (EMACSOPT): Enable module assertions when testing modules. * test/data/emacs-module/mod-test.c (Fmod_test_invalid_store) (Fmod_test_invalid_load): New functions to test module assertions. (emacs_module_init): Bind the new functions. * test/src/emacs-module-tests.el (mod-test-emacs): New constant for the Emacs binary file. (mod-test-file): New constant for the test module file name. (module--test-assertions): New unit test.
* Rework printing of module functionsPhilipp Stephani2017-06-041-2/+2
| | | | | | | | | | | | | | | | | | Fix a FIXME in emacs-module.c. Put the printing into print.c, like other types. * src/print.c (print_vectorlike): Add code to print module functions. * src/emacs-module.c (funcall_module): Stop calling 'module_format_fun_env'. Now that module functions are first-class objects, they can be added to signal data directly. (module_handle_signal): Remove now-unused function 'module_format_fun_env'. * test/src/emacs-module-tests.el (mod-test-sum-test): Adapt unit test. * src/eval.c (funcall_lambda): Adapt call to changed signature of 'funcall_module'.
* Fix a bug when using format field numbersPhilipp Stephani2017-06-031-1/+2
| | | | | | | | | | Previously styled_format overwrite the argument vector. This is no longer possible because there might be more than one specification per argument. Use the existing auxiliary info array instead. * src/editfns.c (styled_format): Record arguments in the info structure instead of overwriting them. * test/src/editfns-tests.el (format-with-field): Add unit test.
