Fix a bug where eql, sxhash-eql, memql, and make-hash-table
were not consistent on NaNs. Likewise for equal,
sxhash-equal, member, and make-hash-table. Some of these
functions ignored NaN significands, whereas others treated
them as significant. It's more logical to treat significands
as significant, and this typically makes eql a bit more
efficient on floats, with just one integer comparison instead
of one to three floating-point comparisons.
* doc/lispref/numbers.texi (Float Basics): Document that
NaNs are never numerically equal, but might be eql.
* src/fns.c (WORDS_PER_DOUBLE): Move to top level of this file.
(union double_and_words): Now named, and at the top level of this file.
(same_float): New function.
(Fmemql, Feql, internal_equal, cmpfn_eql): Use it, so that
the corresponding functions treat NaNs consistently.
(sxhash_float): Simplify based on above-mentioned changes.
* test/src/fns-tests.el (fns-tests-equality-nan): New test.
This causes config.guess to assume support for shell functions,
a safe assumption nowadays.
* build-aux/config.guess, build-aux/config.sub: Copy from Gnulib.
* etc/NEWS: Describe the change.
* lisp/register.el (register-val-describe)
[(window-configuration-p (car val))]: Include the shown
buffers in the return value to make
'register-read-with-preview' more useful. (Bug#30863)
Previously, gpg2 2.0 would be rejected, but the same version installed
as "gpg" would be accepted.
* lisp/epg-config.el (epg-gpg2-minimum-version): New constant.
(epg-config--program-alist) <OpenPGP>: Require a version in 1.4.3..2.0
or 2.1.6+., not just anything above 1.4.3.
(epg-check-configuration): Accept a list of required version
intervals, in addtion to just a single minimum.
On the Hydra test machines, which have gpg 2.0, the symmetric tests
fail.
* test/lisp/epg-tests.el (with-epg-tests): Pass REQUIRE-PUBLIC-KEY to
`epg-tests-find-usable-gpg-configuration' and call it before
`epg-make-context' so that the latter uses the resulting cached
config.
(epg-tests-find-usable-gpg-configuration): Only allow gpg 2.0 for
symmetric operations. Clear `epg--configurations' and don't pass
NO-CACHE to `epg-find-configuration'.
(epg-tests--config-program-alist): Use copy-tree to avoid modifying
the epg-config--program-alist cons values.
* test/lisp/emacs-lisp/package-tests.el (package-test-signed): Allow
running with gpg 2.0.
* test/lisp/emacs-lisp/package-tests.el (package-test-signed): Update
the expected message. The message was changed in 2018-06-25 "Reformat
package.el message strings for future l10n".
(with-package-test, with-fake-help-buffer): Add debug declarations.
* test/lisp/emacs-lisp/package-tests.el (package-test-signed): Stop
using epg-check-configuration and ignore-errors, they're redundant
because epg-find-configuration already does all that.
* test/lisp/epg-tests.el (epg-tests-find-usable-gpg-configuration):
Remove tracing.
(with-epg-tests): Skip test if no gpg config is found.
(epg-decrypt-1 epg-roundtrip-1, epg-sign-verify-1, epg-sign-verify-2)
(epg-import-1): Don't check gpg configuration at top-level, rely on
`with-epg-tests' instead. Checking the gpg configuration requires a
valid HOME (or GNUPGHOME), which is provided by `with-epg-tests'.
* xdisp.c (safe_set_text_properties): New function.
(display_mode_element): Call Fset_text_properties through
internal_condition_case_n, using safe_set_text_properties as a
wrapper. (Bug#32038)

* lisp/emacs-lisp/subr-x.el (string-join): #'-quote function symbol.
(string-trim-left, string-trim-right):
Make better use of substring for minor speedup.

* lisp/custom.el: (custom-available-themes): Use directory-files
instead of performing arbitrary wildcard expansion in file names.
(custom-theme--load-path): Document return value.
* test/lisp/custom-tests.el: New file.
(custom-theme--load-path): New test.
* test/src/thread-tests.el (threads-call-error, threads-custom)

(compile-test-grep-regexps): New tests.
(compile--test-error-line): Return `compilation-message'.
* lisp/vc/smerge-mode.el (smerge-refine-regions): Bind
write-region-inhibit-fsync to t. This was reported in
https://github.com/magit/magit/pull/2834 to give a noticable speedup.
* test/lisp/epg-tests.el (epg-tests--config-program-alist): New
constant, which allows gpg2 version 2.0+.
(epg-tests-find-usable-gpg-configuration): Pass it to
epg-find-configuration.
* src/process.c (Fmake_network_process): On 2018-07-09 "Explicitly
reject :server and :nowait (Bug#31903)", the sense of the SERVER check
was accidentally reversed so that we ended up looking for the wrong
ADDRESS. Reported by T.V Raman in
<https://lists.gnu.org/archive/html/emacs-devel/2018-07/msg00437.html>.
* lisp/subr.el (zerop): Add commentary explaining why moving the
function's location within the file broke bootstrap in
2018-07-10T23:08:58-07:00!contovob@tcd.ie.
rcirc does not retain the server alias on reconnect. As a result, rcirc
fails to re-use server and channel buffers when an alias is used. Further
problems may ensue when aliases are used to differentiate multiple
connections to the same host, for example when using a single IRC bouncer
or proxy to connect to multiple IRC networks.
Save the server alias when connecting to a server so that reconnect will
retain the alias.
* lisp/net/rcirc.el (rcirc-connect): Include server-alias when setting
rcirc-connection-info.
Copyright-paperwork-exempt: yes
