* lisp/progmodes/cperl-mode.el (cperl-electric-else): Don't expand
scalar variables like '$continue' as keywords. (Bug#47902)
* test/lisp/progmodes/cperl-mode-tests.el
(cperl-test-hyperactive-electric-else): Verify that keywords are
expanded but variable names aren't.
This is a useful abstraction, and saves a few levels of indentation in
the test body.
* test/lisp/progmodes/project-tests.el
(project-tests--with-temporary-directory): New helper macro.
(project/quoted-directory): Use it.
This is only a band-aid; it would be better to fix xref.el to work
with quoted filenames as well.
* lisp/progmodes/project.el (project--find-regexp-in-files): Unquote
filenames before passing them to 'xref-matches-in-files'.
* test/lisp/progmodes/project-tests.el (project/quoted-directory):
Also test 'project-find-regexp'.
* test/lisp/progmodes/project-tests.el (project/quoted-directory):
Skip if the 'find' program isn't available. The 'project-files'
function uses 'find' to obtain the list of project files.
Try to search the audit log as well as recent core dumps.
* test/src/emacs-tests.el (emacs-tests--seccomp-debug): New helper
function.
(emacs-tests/seccomp/allows-stdout)
(emacs-tests/seccomp/forbids-subprocess)
(emacs-tests/bwrap/allows-stdout): Use it.
* lisp/progmodes/project.el (project--files-in-directory): Unquote
directory name before passing it to 'find'.
(project--remote-file-names): Requote local filenames if the original
directory is quoted.
* test/lisp/progmodes/project-tests.el (project/quoted-directory): New
unit test.
Allow a condition-case handler on the form (:success BODY) to be
specified as the success continuation of the protected form, with
the specified variable bound to its result.
* src/eval.c (Fcondition_case): Update the doc string.
(internal_lisp_condition_case): Implement in interpreter.
(syms_of_eval): Defsym :success.
* lisp/emacs-lisp/bytecomp.el (byte-compile-condition-case):
Implement in byte-compiler.
* lisp/emacs-lisp/cl-macs.el (cl--self-tco): Allow self-TCO
from success handler.
* doc/lispref/control.texi (Handling Errors): Update manual.
* etc/NEWS: Announce.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases)
(bytecomp-condition-case-success):
* test/lisp/emacs-lisp/cl-macs-tests.el (cl-macs--labels):
Add test cases.
* lisp/net/tramp-sh.el (tramp-do-copy-or-rename-file-out-of-band):
Use `start-process' instead of `start-process-shell-command'.
(tramp-make-copy-program-file-name): Do not quote `localname'.
* test/lisp/net/tramp-tests.el (tramp-method-out-of-band-p): Declare.
(tramp--test-windows-nt-and-batch-p)
(tramp--test-windows-nt-and-pscp-psftp-p): Remove, and also all callees.
(tramp--test-windows-nt-and-out-of-band-p)
(tramp--test-windows-nt-and-scp-p): New defuns.
(tramp-test17-dired-with-wildcards)
(tramp-test40-special-characters)
(tramp-test40-special-characters-with-stat)
(tramp-test40-special-characters-with-perl)
(tramp-test40-special-characters-with-ls, tramp-test41-utf8)
(tramp-test41-utf8-with-stat, tramp-test41-utf8-with-perl)
(tramp-test41-utf8-with-ls): Use them.
* src/character.c (Fstring_width, lisp_string_width): Accept two
optional arguments FROM and TO, to indicate the substring to be
considered.
(Fstring_width): Add caveats in the doc string about display
features ignored by the function. (Bug#47712)
* src/character.h (lisp_string_width): Update prototype.
* src/editfns.c (styled_format): Adjust call of lisp_string_width
to its changed signature.
* test/src/character-tests.el (character-test-string-width): New
file with tests for 'string-width'.
* doc/lispref/display.texi (Size of Displayed Text): Document
caveats of using 'string-width'.
* etc/NEWS: Announce the change.
This is useful when starting Emacs with a Seccomp filter enabled,
e.g. using 'bwrap'.
* lib-src/seccomp-filter.c (main): Generate new Seccomp files.
* lib-src/Makefile.in (all)
(seccomp-filter.bpf seccomp-filter.pfc seccomp-filter-exec.bpf
seccomp-filter-exec.pfc): Generate new Seccomp files.
* .gitignore: Ignore new Seccomp files.
* test/src/emacs-tests.el (emacs-tests/bwrap/allows-stdout): New unit
test.
* lisp/calculator.el (calculator-string-to-number):
The last bugfix changed the code to just blindly replace ".e". This
has some minor problems like making "-." parse as 0.0 instead of -0.0,
and ".1.e1" is parsed as 1 instead of 0.1. Instead, replace the first
"." that is followed by a non-digit with ".0". Since this has had
several problems over the years, add some tests too. (Also, restore
the original if-indentation style.)
The binary uses the 'seccomp' helper library. The library isn't
needed to load the generated Secure Computing filter.
* configure.ac: Check for 'seccomp' header and library.
* lib-src/seccomp-filter.c: New helper binary to generate a generic
Secure Computing filter for GNU/Linux.
* lib-src/Makefile.in (DONT_INSTALL): Add 'seccomp-filter' helper
binary if possible.
(all): Add Secure Computing filter file if possible.
(seccomp-filter$(EXEEXT)): Compile helper binary.
(seccomp-filter.bpf seccomp-filter.pfc): Generate filter files.
* test/src/emacs-tests.el (emacs-tests/seccomp/allows-stdout)
(emacs-tests/seccomp/forbids-subprocess): New unit tests.
* test/Makefile.in (src/emacs-tests.log): Add dependency on the helper
binary.
When passing this option on GNU/Linux, Emacs installs a Secure
Computing kernel system call filter. See Bug#45198.
* configure.ac: Check for seccomp header.
* src/emacs.c (usage_message): Document --seccomp option.
(emacs_seccomp): New wrapper for 'seccomp' syscall.
(load_seccomp, maybe_load_seccomp): New helper functions.
(main): Potentially load seccomp filters during startup.
(standard_args): Add --seccomp option.
* lisp/startup.el (command-line): Detect and ignore --seccomp option.
* test/src/emacs-tests.el (emacs-tests/seccomp/absent-file)
(emacs-tests/seccomp/empty-file)
(emacs-tests/seccomp/file-too-large)
(emacs-tests/seccomp/invalid-file-size): New unit tests.
(emacs-tests--with-temp-file): New helper macro.
* etc/NEWS: Document new --seccomp option.
Edebug doesn't deal well with backtracking out of definitions, see
Bug#41988. Rather than trying to support this rare situation (e.g. by
implementing a multipass parser), prevent it by adding an implicit
gate.
* lisp/emacs-lisp/edebug.el (edebug--match-&-spec-op): Disable
backtracking when hitting a &define keyword.
* test/lisp/emacs-lisp/edebug-tests.el
(edebug-tests-duplicate-&define): New unit test.
(edebug-tests--duplicate-&define): New helper macro.
* doc/lispref/edebug.texi (Backtracking): Mention &define in the list
of constructs that disable backtracking.
* etc/NEWS: Document new behavior.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker): Don't
perform incorrect optimisations when a condition-case variable shadows
another lexical variable.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
New test case.
These changes allow all bytecomp-tests to be run interactively.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp--with-warning-test)
(bytecomp--define-warning-file-test): Interpret any space in the
pattern as arbitrary whitespace to tolerate line breaks.
Don't abuse the expected-failure mechanism when checking
for the expected absense of a warning.
(bytecomp/*.el): Rewrite patterns to work with line breaks
in the middle.
Now all test cases are run with both lexical and dynamic binding
where applicable, comparing interpreted against compiled results.
Previously, almost all tests were only run with dynamic binding
which was definitely not intended.
* test/lisp/emacs-lisp/bytecomp-tests.el
(byte-opt-testsuite-arith-data): Rename to bytecomp-tests--test-cases.
(bytecomp-check-1, bytecomp-explain-1, bytecomp-tests)
(bytecomp-lexbind-tests, bytecomp-lexbind-check-1)
(bytecomp-lexbind-explain-1): Remove.
(bytecomp-tests--eval-interpreted, bytecomp-tests--eval-compiled)
(bytecomp-tests-lexbind, bytecomp-tests-dynbind)
(bytecomp-tests--test-cases-lexbind-only): New.
* lisp/emacs-lisp/cl-macs.el (cl--self-tco): Recognise
`condition-case` handlers as being in the tail position.
* test/lisp/emacs-lisp/cl-macs-tests.el (cl-macs--labels):
Extend test.
* test/infra/gitlab-ci.yml (.test-template): New template.
(test-fast-inotify, test-lisp-inotify, test-lisp-net-inotify)
(test-filenotify-gio, test-gnustep, test-all-inotify): Use it.
* test/lisp/files-tests.el (files-colon-path)
(files-tests-bug-21454): Adapt to MS-DOS/Windows, where
parse-colon-path needs and absolute file name with a drive letter.
(files-tests-file-name-non-special-get-file-buffer): Forcefully
delete the file's buffer if it happens to exist.
