* window.el (display-buffer-alist): Set pop-up-window-min-height
and pop-up-window-min-width in default value. Reported by
Thierry Volpiatto <thierry.volpiatto@gmail.com>. New specifier
other-window-means-other-frame.
(display-buffer-macro-specifiers): Comment out entry for
other-window specifier.
(display-buffer-other-window-means-other-frame): New function.
(display-buffer-normalize-specifiers-1): New arguments
buffer-name and label. Treat other-window case specially.
(display-buffer-normalize-specifiers-2): Treat other-window case
specially.
(display-buffer-normalize-specifiers-3): New function.
(display-buffer-normalize-specifiers): Call
display-buffer-normalize-specifiers-3.
* window.el (display-buffer-normalize-specifiers-1): Don't
check pop-up-frames for 'unset initialization.
(display-buffer-normalize-specifiers-2): Major rewrite using
special-display-p and same-window-p (Bug#8851) and (Bug#8856).
(pop-up-frames, display-buffer-reuse-frames)
(display-buffer-mark-dedicated): Don't initialize to 'unset.
Suggested by David Engster <deng@randomsample.de>.
(even-window-heights): Initialize to 'unset.
(display-buffer-alist-set): Handle new 'unset initializations.
* fileio.c (Finsert_file_contents):
* insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
Remove the old (too-loose) buffer overflow checks.
They weren't needed, since make_gap checks for buffer overflow.
* insdel.c (make_gap_larger): Catch buffer overflows that were missed.
The old code merely checked for Emacs fixnum overflow, and relied
on undefined (wraparound) behavior. The new code avoids undefined
behavior, and also checks for ptrdiff_t and/or size_t overflow.
(display-buffer): Don't check noninteractive when calling
display-buffer-pop-up-frame.
(display-buffer-pop-up-frame): Never pop up a frame in
noninteractive mode (Bug#8857).
* window.el (display-buffer-normalize-specifiers-1): Respect
current value of pop-up-frames for most reasonable values of
second argument of display-buffer (Bug#8865).
auth-source.el (auth-source-save-secrets): New variable to control if secret tokens should be saved encrypted.
(auth-source-netrc-parse, auth-source-netrc-search): Pass the file name to `auth-source-netrc-normalize'.
(with-auth-source-epa-overrides): Add convenience macro. Don't depend on the EPA variables being defined.
(auth-source-epa-make-gpg-token): Convert text to a "gpg:" token.
(auth-source-netrc-normalize): Convert "gpg:" tokens back to text in the lexical-let closure.
(auth-source-netrc-create): Create "gpg:" tokens according to `auth-source-save-secrets'.
This is for the case where you want to force a `plain' network
connection, but the protocol still requires the capabilitiy command
(i.e., SMTP and EHLO).
* window.el (display-buffer-alist): Trim default value to avoid
popping up a new frame (Bug#8857) or reusing an arbitrary window
on another frame.
(display-buffer): Do not fall back on popping up a new frame in
batch mode (Bug#8857).
(Fsafe_length): Return a float if the value is not representable
as a fixnum. This shouldn't happen except in contrived situations.
Use same QUIT_COUNT_HEURISTIC as Flength now does.
Use EMACS_INT, not int, to avoid unwanted truncation on 64-bit hosts.
Check for QUIT every 1024 entries rather than every other entry;
that's faster and is responsive enough. Report an error instead of
overflowing an integer.
(header_size, word_size): New constants.
(allocate_vectorlike): Don't check size overflow here.
(allocate_vector): Check it here instead, since this is the only
caller of allocate_vectorlike that could cause overflow.
Check that the new vector's length is representable as a fixnum.
