* Disallow string data resizing (bug#79784)Mattias Engdegård2025-08-241-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | Only allow string mutation that is certain not to require string data to be resized and reallocated: writing bytes into a unibyte string, and changing ASCII to ASCII in a multibyte string. This ensures that mutation will never transform a unibyte string to multibyte, that the size of a string in bytes never changes, and that the byte offsets of characters remain the same. Most importantly, it removes a long-standing obstacle to reform of string representation and allow for future performance improvements. * src/data.c (Faset): Disallow resizing string mutation. * src/fns.c (clear_string_char_byte_cache): * src/alloc.c (resize_string_data): Remove. * test/src/data-tests.el (data-aset-string): New test. * test/lisp/subr-tests.el (subr--subst-char-in-string): Skip error cases. * test/src/alloc-tests.el (aset-nbytes-change): Remove test that is no longer relevant. * doc/lispref/strings.texi (Modifying Strings): * doc/lispref/sequences.texi (Array Functions): * doc/lispref/text.texi (Substitution): Update manual. * etc/NEWS: Announce.

* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-131-1/+1
| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.
* Deprecate copy-record in favor of copy-sequencePaul Eggert2017-04-071-1/+1
| | | | | | | | | | | | | | | | | Since copy-sequence seems to be needed anyway for records, have it work on records, and remove copy-record as being superfluous. * doc/lispref/records.texi (Records, Record Functions): * lisp/emacs-lisp/cl-macs.el (cl-defstruct): * lisp/emacs-lisp/eieio.el (make-instance, clone): * test/src/alloc-tests.el (record-3): Use copy-sequence, not copy-record, to copy records. * doc/lispref/sequences.texi (Sequence Functions) (Array Functions): Document that aref and copy-sequence work on records. * etc/NEWS: Omit copy-record. * src/alloc.c (Fcopy_record): Remove. * src/data.c (Faref): Document that arg can be a record. * src/fns.c (Fcopy_sequence): Copy records, too.

Define `Qrecordp'. (Faref, Faset): Work with records. * src/fns.c (Flength): Work with records. * src/lisp.h (prec_type): Add PVEC_RECORD.
