* test/src/data-tests.el (data-tests-kill-all-local-variables): New test.
* src/buffer.c (swap_out_buffer_local_variables): Remove.
Fuse the body of its loop into that of reset_buffer_local_variables.
(Fkill_buffer, Fkill_all_local_variables): Don't call it any more.
(reset_buffer_local_variables): Make sure the buffer's local binding
is swapped out before removing it from the alist (bug#30846).
Call watchers before actually killing the var.
* src/data.c (Fmake_local_variable): Simplify.
Use swap_in_global_binding to swap out any local binding, instead of
a mix of find_symbol_value followed by messing with where&found.
Don't call swap_in_symval_forwarding since the currently swapped
binding is never one we've modified.
(Fkill_local_variable): Use swap_in_global_binding rather than messing
with where&found to try and trick find_symbol_value into doing the same.
* src/alloc.c (mark_localized_symbol): 'where' can't be a frame any more.
Unchain all dead markers with a single scan of the markers list,
instead of calling the O(N) 'unchain_marker' N times.
(unchain_dead_markers): New function.
(sweep_buffers): Use it.
(gc_sweep): Sweep buffers before markers.
(sweep_misc): Check that markers have been unchained when reclaiming them.
* doc/lispref/variables.texi (Defining Variables)
(Using Lexical Binding):
* doc/lispref/compile.texi (Compiler Errors): Emphasize that omitting
VALUE for `defvar' marks the variable special only locally.
* doc/lispref/variables.texi (Using Lexical Binding): Add example of
using `defvar' without VALUE.
This fixes a bug where a byte-compiler running on 64-bit Emacs
optimized (lsh -1 -1) to #x1fffffffffffffff, an optimization
that is incorrect for .elc files intended for either 32- or
64-bit Emacs. While I was in the neighborhood, I noticed other
glitches in the lists of pure and side-effect-free functions, and
fixed the errors that I found.
* lisp/emacs-lisp/byte-opt.el (side-effect-free-fns):
Move some functions here from side-effect-and-error-free-fns,
since they can now signal errors. The affected functions are
current-time-string, current-time-zone,
line-beginning-position, line-end-position. Rename langinfo
to locale-info. Add logcount. Remove string-to-int.
(side-effect-and-error-free-fns): Remove minibuffer-window, a
function that can signal errors, and that is already in
side-effect-free-fns.
(pure-fns): Remove ash, lsh, and logb, since they are
platform-dependent and .elc files should be
platform-independent. Add %, logand, logcount. Sort.
Clarify what is meant by “pure”.
Fix a portability bug when emacs-module-tests.el is byte-compiled
with a 32-bit Emacs (where #x20000000 evaluates to a
floating-point number) and then is run on a 64-bit Emacs (where
the floating-point number causes a test failure).
* test/src/emacs-module-tests.el (mod-test-sum-test):
Don’t assume #x20000000 can be represented as an Emacs integer.
* lisp/net/tramp.el (tramp-handle-substitute-in-file-name): Drop volume
letter of localname substitution. Reported by Chris Zheng
<chriszheng99@gmail.com>.
* test/lisp/net/tramp-tests.el (tramp-test39-utf8)
(tramp-test39-utf8-with-stat, tramp-test39-utf8-with-perl)
(tramp-test39-utf8-with-ls): Tag the tests as :unstable.
* test/lisp/emacs-lisp/eieio-tests/eieio-test-persist.el
(eieio-test-persist-hash-and-vector,
eieio-test-persist-interior-lists): Persistence does not currently
handle deeply-nested objects. Expect current failures, and mark for
future fixes.
* lisp/emacs-lisp/eieio-base.el (eieio-persistent-validate/fix-slot-value):
`object-write' may quote lists inside hash tables and vectors, so
unquote those lists here.
This patch allows the eieio-persistent write/restore process to
perform a clean round trip. It only handles a very specific and
limited range of object structures, but at least the write and read
procedures match.
* lisp/emacs-lisp/eieio-base.el (eieio-persistent-validate/fix-slot-value):
The function `eieio-persistent-slot-type-is-class-p' could return
either a single class, or a list of classes.
* test/lisp/emacs-lisp/eieio-tests/eieio-test-persist.el:
(hash-equal): New comparison test for hash-tables.
(persist-test-save-and-compare): Use test for hash-tables.
(eieio-test-persist-hash-and-vector,
eieio-test-persist-interior-lists): New tests.
* test/src/data-tests.el (data-tests-popcnt):
Don’t assume Emacs integers can represent 32-bit quantities.
Change to a simple and straightforward approach, since runtime
performance is not important here.
* lisp/vc/vc-git.el (vc-git-stash-read-history)
(vc-git-stash-read): New history variable and function.
(vc-git-stash-show, vc-git-stash-apply, vc-git-stash-pop): Update
their interactive specifications.
* test/lisp/emacs-lisp/eieio-tests/eieio-test-methodinvoke.el:
* test/lisp/emacs-lisp/eieio-tests/eieio-test-persist.el:
* test/lisp/emacs-lisp/eieio-tests/eieio-tests.el:
Remove obsolete name args where not being explicitly tested.
* doc/lispref/variables.texi (Generalized Variables)
(Setting Generalized Variables): Define a generalized variable as something
setf can write to. Remove the insinuation that hackers have poor memories.
State explicitly that the list of GVs given is complete. Remove the
suggestion that `setf' has superseded, or is in the process of superseding,
`setq'. Make minor corrections to the English.
* doc/emacs/files.texi (Reverting): Mention that Aut-Revert
applies to Dired buffers as well. Suggested by Michael Albinus
<michael.albinus@gmx.de> in emacs-manual-bugs@gnu.org.
* doc/emacs/dired.texi (Dired): Mention that Dired works with
remote directories.
(Dired Enter): ls-lisp is used on some remote systems as well.
(Dired Navigation): Mention and index the command names.
(Dired Deletion): Document the 'always' value of
dired-recursive-deletes. Mention the alternative deletion method.
(Marks vs Flags): Fix spelling of Auto-Revert mode. Document what
marking does on a subdirectory header line.
(Operating on Files): Document that 'Z' uses gzip or compress.
(Comparison in Dired): Mention ediff-files.
(Misc Dired Features): Fix a typo. Suggested by Michael Albinus
<michael.albinus@gmx.de> in emacs-manual-bugs@gnu.org.
It highlights normal variable names in perl programs (Bug#30812).
* lisp/progmodes/perl-mode.el (perl-imenu-generic-expression)
(perl-font-lock-keywords-2): Restore values prior to Bug#27613 fix.
Don't merge to master, we will fix Bug#27613 properly there (it's too
close to release to do that on emacs-26).
Backport from master.
Problem reported by Ulrich Mueller; fix suggested by Eli Zaretskii
and Andreas Schwab (Bug#30855).
* src/alloc.c (mark_memory): Call mark_maybe_object only on
pointers that are properly aligned for Lisp_Object.
