ac7936cb8f Rename thread-alive-p to thread-live-p
3d09d533d1 rcirc: Document /reconnect as a built-in command (Bug#29656)
a1e615618d * test/lisp/calc/calc-tests.el (calc-imaginary-i): New test.
* doc/lispref/threads.texi (Basic Thread Functions): Use thread-live-p.
* etc/NEWS: 'thread-alive-p' has been renamed to 'thread-live-p'.
* src/thread.c (thread_live_p): Rename from thread_alive_p. Adapt
all callees.
(Fthread_live_p): Rename from Fthread_alive_p.
(syms_of_threads): Make thread-alive-p an alias of thread-live-p.
* test/src/thread-tests.el (all): Replace `thread-alive-p' by
`thread-live-p'.
(threads-live): Rename from `threads-alive'.
* src/bignum.c: Include stdlib.h, for abs.
(bignum_bufsize, bignum_to_c_string): New functions.
* src/bignum.c (bignum_to_string):
* src/print.c (print_vectorlike): Use them.
* src/editfns.c (styled_format): Instead of having a separate
buffer for sprintf (which does not work for bignums), just append
to the main buffer. When formatting bignums, add support for the
standard integer flags -, #, 0, + and space. Fix some comments.
Capitalize properly when formatting bignums with %X. Use
functions like c_isdigit rather than reinventing the wheel.
Simplify computation of excess precision.
* src/print.c: Do not include bignum.h; no longer needed.
(print_vectorlike): Avoid recalculating string length.
* test/src/editfns-tests.el (format-bignum):
Test some of the above fixes.

* src/emacs-module.c (module_free_global_ref): Compare a value to be
freed with all entries of the list.

function.
(emacs_module_init): Make it accessible from Lisp.

Also, since Emacs historically reported a range error when
rounding operations overflowed, do that consistently for all
bignum overflows.
* doc/lispref/errors.texi (Standard Errors):
* doc/lispref/numbers.texi (Integer Basics): Document range errors.
* src/alloc.c (range_error): Rename from integer_overflow.
All uses changed.
* src/floatfns.c (rounding_driver): When the result of a floating
point rounding operation does not fit into a fixnum, put it
into a bignum instead of always signaling an range error.
* test/src/floatfns-tests.el (divide-extreme-sign):
These tests now return the mathematically-correct answer
instead of signaling an error.
(bignum-round): Check that integers round to themselves.
Problem reported by Andy Moreton (Bug#32463#35 (d)).
* src/floatfns.c (rounding_driver): Change the signature
of the integer rounder to use mpz_t rather than EMACS_INT.
All uses changed. Support bignums.
(ceiling2, floor2, truncate2, round2): Remove.
All uses changed to rounddiv_q or to a GMP library function.
(rounddiv_q): New function.
* test/src/floatfns-tests.el (bignum-round): New test.
Problem reported by Stefan Monnier (Bug#32476).
* src/lread.c (string_to_number): Don't pass leading "+"
or trailing "." or junk to make_bignum_str.
* test/src/lread-tests.el (lread-string-to-number-trailing-dot):
New test.
I audited use of lsh in the Lisp source code, and fixed the
glitches that I found. While I was at it, I replaced uses of lsh
with ash when either will do. Replacement is OK when either
argument is known to be nonnegative, or when only the low-order
bits of the result matter, and is a (minor) win since ash is a bit
more solid than lsh nowadays, and is a bit faster.
* lisp/calc/calc-ext.el (math-check-fixnum):
Prefer most-positive-fixnum to (lsh -1 -1).
* lisp/vc/vc-hg.el (vc-hg-state-fast): When testing fixnum width,
prefer (zerop (ash most-positive-fixnum -32)) to (zerop (lsh -1
32)) (Bug#32485#11).
* lisp/emacs-lisp/bytecomp.el (byte-compile-lapcode):
Tighten sanity-check for bytecode overflow, by checking that the
result of (ash pc -8) is nonnegative. Formerly this check was not
needed since lsh was used and the number overflowed differently.
* lisp/net/dns.el (dns-write): Fix some obvious sign typos in
shift counts. Evidently this part of the code has never been

Also, fix bug when N is a positive bignum, a problem reported
by Eli Zaretskii and Pip Cet in:
https://lists.gnu.org/r/emacs-devel/2018-08/msg00690.html
* src/fns.c (Fnthcdr): If a cycle is found, reduce the count
modulo the cycle length before continuing. This reduces the
worst-case cost of (nthcdr N L) from N to min(N, C) where C is
the number of distinct cdrs of L. Reducing modulo the cycle
length also allows us to do arithmetic with machine words
instead of with GMP.
* test/src/fns-tests.el (test-nthcdr-circular): New test.
Problem and initial solution reported by Andy Moreton in:
https://lists.gnu.org/r/emacs-devel/2018-08/msg00503.html
* doc/lispref/numbers.texi (Math Functions): expt integer
overflow no longer causes truncation; it now signals an error
since bignum overflow is a big deal.
* src/floatfns.c (Fexpt): Support bignum arguments.
* test/src/floatfns-tests.el (bignum-expt): New test.
* src/data.c (isnan): Remove, as we can assume C99.
(bignumcompare): Remove, folding its functionality
into arithcompare.
(arithcompare): Compare bignums directly here.
Fix bugs when comparing NaNs to bignums.
When comparing a bignum to a fixnum, just look at the
bignum’s sign, as that’s all that is needed.
Decrease scope of locals when this is easy.
* test/src/data-tests.el (data-tests-bignum): Test bignum vs NaN.
* doc/lispref/numbers.texi (Bitwise Operations): Document that
the traditional (lsh A B) behavior is for fixnums, and that it
is an error if A and B are both negative and A is a bignum.
See Bug#32463.
* lisp/subr.el (lsh): New function, moved here from src/data.c.
* src/data.c (ash_lsh_impl): Remove, moving body into Fash
since it’s the only caller now.
(Fash): Check for out-of-range counts. If COUNT is zero,
return first argument instead of going through libgmp. Omit
lsh code since lsh is now done in Lisp. Add code for shifting
fixnums right, to avoid a round trip through libgmp.
(Flsh): Remove; moved to lisp/subr.el.
* test/lisp/international/ccl-tests.el (shift):
Test for traditional lsh behavior, instead of assuming
lsh is like ash when bignums are present.
* test/src/data-tests.el (data-tests-logand)
(data-tests-logior, data-tests-logxor, data-tests-ash-lsh):
New tests.
These operations incorrectly treated negative fixnums as
bignums greater than most-positive-fixnum.
* src/alloc.c (mpz_set_intmax_slow): Avoid undefined
behavior if signed unary negation overflows, while
we’re in the neighborhood.
(mpz_set_uintmax_slow): Remove. All uses removed.
* src/data.c (arith_driver): Treat fixnums as signed, not
unsigned, even for logical operations.
* src/lisp.h (mpz_set_uintmax): Remove. All uses removed.
* test/src/data-tests.el (data-tests-logand)
(data-tests-logior, data-tests-logxor): New tests.

New constant.
(data-tests-=, data-tests-<, data-tests->, data-tests-<=)
(data-tests->=, data-tests-min): Use it.
* src/editfns.c (styled_format): Add the spec beginning index
to the info recorded for each format spec, and use it to
detect the case that a format spec and its text property end
where the next spec with another property begins. (Bug#32404)
* test/src/editfns-tests.el (format-properties): Add tests for
bug#32404.
This is in preparation for using Gnulib regex for etags,
to avoid collisions in include directives.
* src/regex-emacs.c: Rename from src/regex.c.
* src/regex-emacs.h: Rename from src/regex.h. All uses changed.
* test/src/regex-emacs-tests.el: Rename from test/src/regex-tests.el.
* src/fns.c (cmpfn_eql, hashfn_eql): Handle bignums.
(sxhash_bignum): New function.
(sxhash): Use it.
* test/src/fns-tests.el (test-bignum-hash): New test.
Optionally treat integers as signed numbers with %o
and %x format specifiers, instead of treating them as
a machine-dependent two’s complement representation.
This option is more machine-independent, allows formats
like "#x%x" to be useful for reading later, and is
better-insulated for future changes involving bignums.
Setting the new variable ‘binary-as-unsigned’ to nil
enables the new behavior (Bug#32252).
This is a simplified version of the change proposed in:
https://lists.gnu.org/r/emacs-devel/2018-07/msg00763.html
I simplified that proposal by omitting bitwidth modifiers, as
I could not find an any example uses in the Emacs source code
that needed them and doing them correctly would have been
quite a bit more work for apparently little benefit.
* doc/lispref/strings.texi (Formatting Strings):
Document that %x and %o format negative integers in a
platform-dependent way. Also, document how to format
numbers so that the same values can be read back in.
* etc/NEWS: Document the change.
* src/editfns.c (styled_format): Treat integers as signed
numbers even with %o and %x, if binary-as-unsigned is nil.
Support the + and space flags with %o and %x, since they’re
about signs.
(syms_of_editfns): New variable binary-as-unsigned.
* test/src/editfns-tests.el (read-large-integer):
Test that maximal integers can be read after printing
with all integer formats, if binary-as-unsigned is nil.
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.
