* | | Fix ambiguity in nil DST flagPaul Eggert2018-09-211-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Formerly nil meant both that DST was not in effect and that the DST flag was unknown, and different functions interpreted the flag differently. Now the meaning is consistently nil for DST not in effect, and -1 for DST flag not known. * doc/lispref/os.texi (Time Conversion): The DST slot is now three-valued, not two-. * doc/misc/emacs-mime.texi (time-date): Adjust to new behavior. * etc/NEWS: Mention this. * lisp/calendar/parse-time.el (parse-time-string): * src/editfns.c (Fdecode_time): Return -1 for unknown DST flag. * test/lisp/calendar/parse-time-tests.el (parse-time-tests): Adjust tests to match new behavior, and add a new test for nil vs -1.

* | | ; * etc/NEWS: assoc-delete-all fixGlenn Morris2018-09-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is a mess. This function was added in master in afba4ccb8b8, undocumented. It was then tweaked and documented in 9824885fabe. Much later in cc233365a92 the original untweaked and undocumented version was backported to emacs-26. This was independently redocumented in emacs-26 in cc8f334d2da, which conflicted with the interface changes that had been made on master.

* | | Avoid libgmp aborts by imposing limitsPaul Eggert2018-08-211-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libgmp calls ‘abort’ when given numbers too big for its internal data structures. The numeric limit is large and platform-dependent; with 64-bit GMP 6.1.2 it is around 2**2**37. Work around the problem by refusing to call libgmp functions with arguments that would cause an abort. With luck libgmp will have a better way to do this in the future. Also, introduce a variable integer-width that lets the user control how large bignums can be. This currently defaults to 2**16, i.e., it allows bignums up to 2**2**16. This should be enough for ordinary computation, and should help Emacs to avoid thrashing or hanging. Problem noted by Pip Cet (Bug#32463#71). * doc/lispref/numbers.texi, etc/NEWS: Document recent bignum changes, including this one. Improve documentation for bitwise operations, in the light of bignums. * src/alloc.c (make_number): Enforce integer-width. (integer_overflow): New function. (xrealloc_for_gmp, xfree_for_gmp): Move here from emacs.c, as it's memory allocation. (init_alloc): Initialize GMP here, rather than in emacs.c. (integer_width): New var. * src/data.c (GMP_NLIMBS_MAX, NLIMBS_LIMIT): New constants. (emacs_mpz_size, emacs_mpz_mul) (emacs_mpz_mul_2exp, emacs_mpz_pow_ui): New functions. (arith_driver, Fash, expt_integer): Use them. (expt_integer): New function, containing integer code that was out of place in floatfns.c. (check_bignum_size, xmalloc_for_gmp): Remove. * src/emacs.c (main): Do not initialize GMP here. * src/floatfns.c (Fexpt): Use expt_integer, which now contains integer code moved from here. * src/lisp.h (GMP_NUMB_BITS): Define if gmp.h doesn’t.

The immediate motivation for this change is to free up an enum Lisp_Type tag value, a scarce resource that can be better used elsewhere. However, this change is worthwhile in its own right, as it improves performance slightly on my platform, 0.3% faster for 'make compile-always' on Fedora 28, and it simplifies the garbage collector and interpreter (Bug#32405). * doc/lispref/internals.texi (Garbage Collection): * etc/NEWS: Document change to garbage-collect return value. * src/alloc.c (total_markers, total_free_markers): (union aligned_Lisp_Misc, MARKER_BLOCK_SIZE) (struct marker_block, marker_block, marker_block_index) (misc_free_list, allocate_misc, live_misc_holding) (live_misc_p, sweep_misc): * src/lisp.h (lisp_h_MARKERP, lisp_h_MISCP, MARKERP, MISCP) (Lisp_Misc, enum Lisp_Misc_Type, Lisp_Misc_Free) (Lisp_Misc_Marker, Lisp_Misc_Overlay, Lisp_Misc_Finalizer) (Lisp_Misc_Ptr, Lisp_Misc_User_Ptr, Lisp_Misc_Limit) (Lisp_Misc_Bignum) (XSETMISC, struct Lisp_Misc_Any, XMISCANY, XMISCTYPE) (struct Lisp_Free, union Lisp_Misc, XMISC): Remove.
