* src/alloc.c (mark_maybe_object, mark_maybe_objects): Remove.
(mark_objects): New function.
* src/eval.c (mark_specpdl): Use mark_objects instead of
mark_maybe_objects, since the array now has only valid Lisp objects.
* src/lisp.h (SAFE_ALLOCA_LISP_EXTRA): When allocating a large
array, clear it so that it contains only valid Lisp objects. This
is simpler and safer, and does not hurt performance significantly
on my usual benchmark as the code is executed so rarely.
This lets Emacs avoid marking some garbage as if it were in use.
On one test platform (RHEL 7.8, Intel Xeon Silver 4116) it
sped up ‘cd lisp; make compile-always’ by a bit over 1%.
* src/alloc.c (live_string_holding, live_cons_holding)
(live_symbol_holding, live_large_vector_holding)
(live_small_vector_holding):
Count only pointers that point to a struct component,
or are a tagged pointer to the start of the struct.
Exception: for non-bool-vector pseudovectors,
count any pointer past the header, since it’s too much
of a pain to write code for every pseudovector.
(live_vector_pointer): New function.
* src/alloc.c (mark_memory): Do not bother using mark_maybe_object
on the stack, since mark_maybe_pointer now marks everything that
mark_maybe_object would.
On --with-wide-int platforms where Lisp_Object can be
put into non-adjacent registers, mark_maybe_pointer failed
to mark a float whose only reference was as a tagged pointer.
* src/alloc.c (live_float_holding): New function,
a generalization of the old live_float_p.
(live_float_p): Use it.
(mark_maybe_pointer): Use live_float_holding, not live_float_p.
* lisp/play/life.el (life): New defgroup.
(life-step-time): New defcustom (lower default from 1 to 0.5).
(life): Use above new variable. Make prefix arguments set step time
in tenths of a second instead of whole seconds.
(life-expand-plane-if-needed): Rename argument to step-time.
(life-setup): Fix running `M-x life' with existing buffer.
(life-patterns): Add three more classic patterns.
* lisp/wid-edit.el (file widget): Add a :match and a :validate
function to the 'file widget, to be able to check if the widget
value is an existent file, when required (bug#25678).
Having it placed in the beginning of that hook meant it was mostly
impossible to track the args to a function call while writing it from
scratch, since most compilers issue a diagnostic about incorrect
number of arguments.
See bug#43103.
* lisp/progmodes/flymake.el (flymake-mode): Lower priority of
flymake-eldoc-function.
* doc/lispref/minibuf.texi (Text from Minibuffer): Document it.
* lisp/help-fns.el (describe-function): Adjust the caller.
* lisp/minibuffer.el (format-prompt): Interpret a nil default
value as "no default".
This eldoc-documentation-strategy function didn't always obey protocol
since it returned nil sometimes, which the eldoc engine took it as a
hint for the "old" protocol to clear the echo area.
* lisp/emacs-lisp/eldoc.el (eldoc-documentation-enthusiast):
Return t.
(Version): Bump to 1.9.0
* src/fileio.c (Fexpand_file_name): Restore pre-August-26
behavior, if DOS_NT. This should fix the recently-introduced
expand-file-name bugs on DOS_NT (Bug#26911).
* lisp/mail/smtpmail.el (smtpmail-try-auth-methods): Let the
authorization credentials have an entry with key :smtp-auth containing
a preferred authentication mechanism.
* lisp/progmodes/compile.el (compilation-error-regexp-alist-alist):
Extend regular expression to match optional column numbers.
*
test/lisp/progmodes/compile-tests.el (compile-tests--test-regexps-data):
Add a test.
* test/lisp/progmodes/compile-tests.el (compile-test-error-regexps):
Update the total number of compilation errors in a test.
* etc/compilation.txt: Update compilation.txt with the newly supported
message format.
* etc/NEWS: Advertise the feature.
* lisp/progmodes/project.el (project-async-shell-command)
(project-shell-command): New commands to run 'async-shell-command'
and 'shell-command' in project's root directory.
(project-prefix-map): Bind commands to '!' and '&'.
* doc/emacs/maintaining.texi (Project File Commands): Document the
new commands.
* etc/NEWS: Announce the new commands.
* lisp/emacs-lisp/warnings.el (display-warning-minimum-level)
(log-warning-minimum-level): Make XEmacs compat aliases into obsolete
aliases for 'warning-minimum-level' and 'warning-minimum-log-level'.
This allows override of the read process for eieio-persistent objects,
providing the possibility of matching read/write customization for
eieio-persistent subclasses.
* lisp/emacs-lisp/eieio-base.el (eieio-persistent-make-instance): New
generic function for constructing instances from object data written
to disk. Previously known as eieio-persistent-convert-list-to-object.
Actual object creation (in `make-instance') will later run all slot
values through cl-typep, which does a better job of validation. This
validation is redundant, and slows the read process down.
* lisp/emacs-lisp/eieio-base.el (eieio-persistent-fix-value): Rename
from `eieio-persistent-validate/fix-slot-value', as we no longer
validate, and we don't care about the slot definition.
(eieio-persistent-slot-type-is-class-p): Delete function.
(eieio-persistent-convert-list-to-object): Still call
`eieio--full-class-object', to trigger an autoload if necessary, but
discard the return value.
* lisp/progmodes/cperl-mode.el (cperl-fix-line-spacing): Fix Bug#18985.
Hash keys or function names starting with a Perl keyword followed
by an underscore (as in "for_me" are no longer split into two words
by M-x indent-region.
The bug was that (expand-file-name "~") returned something
like "/home/eggert/" instead of "/home/eggert".
Problem reported by Mattias Engdegård (Bug#26911#27).
* src/fileio.c (Fexpand_file_name): When concatenating NEWDIR to
NM, instead of stripping trailing slashes from NEWDIR (which can
turn non-symlinks into symlinks), strip leading slashes from NM.
This also simplifies the code by removing no-longer-needed DOS_NT
special-casing. Also, remove an unnecessary ‘target[length] = 0;’
as that byte will be overwritten by the next memcpy anyway.
* test/src/fileio-tests.el (fileio-tests--HOME-trailing-slash):
New test.
