* lib/Makefile.in (clean): Remove *-t files.
(mostlyclean): Remove MOSTLYCLEANFILES that are not *-t files.
This removes files like lib/getopt.h that should be removed
even if this configuration did not need to build them.
(maintainer-clean): Remove TAGS here, not in distclean,
to be consistent with ../src/Makefile.in.
In Greek, a sigma character has two lower case forms which depend on
their position in the word. Implement logic determining it.
* src/casefiddle.c (struct casing_context, case_character_impl): Don’t
assume inword is true when flag is CASE_UP and false when flag is
CASE_DOWN. For final sigma detection we need this information tracked
reliably;.
(CAPITAL_SIGMA, SMALL_SIGMA, SMALL_FINAL_SIGMA): New macros defining
Unicode code point of different forms of sigma letter.
(case_character): Implement support for final sigma casing.
(do_casify_multibyte_string, do_casify_multibyte_region): Update after
changes to case_character.
* test/src/casefiddle-tests.el (casefiddle-tests-casing): Add test
cases for final sigma.
Implement unconditional special casing rules defined in Unicode standard.
Among other things, they deal with cases when a single code point is
replaced by multiple ones because single character does not exist (e.g.
‘fi’ ligature turning into ‘FL’) or is not commonly used (e.g. ß turning
into SS).
* admin/unidata/SpecialCasing.txt: New data file pulled from Unicode
standard distribution.
* admin/unidata/README: Mention SpecialCasing.txt.
* admin/unidata/unidata-get.el (unidata-gen-table-special-casing,
unidata-gen-table-special-casing--do-load): New functions generating
‘special-uppercase’, ‘special-lowercase’ and ‘special-titlecase’
character Unicode properties built from the SpecialCasing.txt Unicode
data file.
* src/casefiddle.c (struct casing_str_buf): New structure for
representing short strings used to handle one-to-many character
mappings.
(case_character_imlp): New function which can handle one-to-many
character mappings.
(case_character, case_single_character): Wrappers for the above
functions. The former may map one character to multiple (or no)
code points while the latter does what the former used to do (i.e.
handles one-to-one mappings only).
(do_casify_natnum, do_casify_unibyte_string,
do_casify_unibyte_region): Use case_single_character.
(do_casify_multibyte_string, do_casify_multibyte_region): Support new
features of case_character.
* (do_casify_region): Updated to reflact do_casify_multibyte_string
changes.
(casify_word): Handle situation when one character-length of a word
can change affecting where end of the word is.
(upcase, capitalize, upcase-initials): Update documentation to mention
limitations when working on characters.
* test/src/casefiddle-tests.el (casefiddle-tests-char-properties):
Add test cases for the newly introduced character properties.
(casefiddle-tests-casing): Update test cases which are now passing.
* test/lisp/char-fold-tests.el (char-fold--ascii-upcase,
char-fold--ascii-downcase): New functions which behave like old ‘upcase’
and ‘downcase’.
(char-fold--test-match-exactly): Use the new functions. This is needed
because otherwise fi and similar characters are turned into their multi-
-character representation.
* doc/lispref/strings.texi: Describe issue with casing characters versus
strings.
* doc/lispref/nonascii.texi: Describe the new character properties.
No functional changes at this time but splitting casify_region into
a function dealing with multibyte and another dealing with unibyte
buffers will make future code changes slightly easier.
* src/casefiddle.c (casify_region): Move most of the code into two
new functions:
(do_casify_multibyte_region, do_casify_unibyte_region): new functions.
* src/casefiddle.c (struct casing_context, prepare_casing_context): Add
titlecase_char_table member. It’s set to the ‘titlecase’ Unicode
property table if capitalisation has been requested.
(case_character): Make use of the titlecase_char_table to title-case
initial characters when capitalising.
* test/src/casefiddle-tests.el (casefiddle-tests--characters,
casefiddle-tests-casing): Update test cases which are now passing.
Move single-character casing logic into a separate function so that
it is collected in a single place. This will make future changes to
the logic easier. This commit introduces no functionality changes.
* src/casefiddle.c (struct casing_context, prepare_casing_context): New
sturcture for saving casing context and function to initialise it.
(case_character): New function which cases character base on provided
context.
(do_casify_integer, do_casify_multibyte_string,
do_casify_unibyte_string, casify_object, casify_region): Convert to
use casing_context and case_character.
casify_object had three major cases to cover and those were mostly
independent of each other. Move those branches to separate function
so it’s easier to comprehend each individual case.
While at it, use somewhat more descriptive ch and cased variable names
rather than c and c1.
This commit introduces no functional changes.
* src/casefiddle.c (casify_object): Split into…
(do_casify_integer, do_casify_multibyte_string,
do_casify_unibyte_string): …new functions.
* objects.texi (Record Type): improve description of what
`type-of' returns for records.
(Type Descriptors): new section.
* elisp.texi: reference it.
* records.texi (Records): reference it. Document behaviour when type
slot is a record.
* alloc.c (Fmake_record, Frecord): mention type desciptors.
* lisp/loadup.el: Perform the "dump" or "bootstrap" actions like
calling dump-emacs only if dump-emacs is defined; otherwise, don't
treat those command-line argument specially.
Having a command-line argument of "dump" or "bootstrap" would trigger
behavior like not installing signal handlers. In CANNOT_DUMP modes,
we should get signal handlers installed regardless of whatever funny
file names we decide to edit.
src/emacs.c (main) [CANNOT_DUMP]: Don't enable the "dumping"
alterations to initialization that prepares the process for unexec.
During a bootstrap, loading rmail.el invokes movemail to determine its
flavor, but call-process doesn't work if exec-path is nil.
* lisp/loadup.el: Only clear exec-path if dumping.
* lisp/textmodes/sgml-mode.el (sgml-syntax-propertize-rules): New
defconst.
(sgml-syntax-propertize): Use it.
(sgml--find-<>-backward): New function.
(sgml-parse-tag-backward): Use it.
* lisp/subr.el (provided-mode-derived-p): New function.
(derived-mode-p): Use it.
* lisp/emulation/viper.el (viper-mode): Use derived-mode-p.
(this-major-mode-requires-vi-state): Use provided-mode-derived-p.
(set-viper-state-in-major-mode): Use derived-mode-p.
* src/data.c (Frecordp): Rename from Frecordp_p, for consistency.
* src/data.c (syms_of_data):
* src/frame.c (syms_of_frame): Put all the primitive type names
together, under the "Types that type-of returns" comment.
* doc/lispref/records.texi (Records): Mention size limit.
* etc/NEWS: Mention records.
* src/alloc.c (allocate_pseudovector, allocate_record):
Prefer 'PSEUDOVECTOR_SIZE_MASK' to its definiens.
(allocate_record): Check arg range here, not in callers, as this
simplifies the code. Use allocate_vectorlike instead of
allocate_vector, to avoid duplicate runtime tests.
(Fmake_record, record): Don't mention PSEUDOVECTOR_SIZE_BITS in
the doc string, as it is not visible to the user.
(Fmake_record, record, Fcopy_record):
Prefer make_lisp_ptr to XSETVECTOR.
(record): Broaden memcpy to copy the type, too.
`call-process' doesn't respect file name handlers in
`default-directory', so `file-name-non-special' has to resolve them
for `process-file', `start-file-process', and
`shell-command' (Bug#25949).
* lisp/files.el (file-name-non-special): Also resolve default
directory for 'process-file', 'start-file-process', and
'shell-command'.
* test/lisp/files-tests.el
(files-tests--file-name-non-special--subprocess): Add unit test.
Quoted file names need to be unquoted before passed to
subprocesses (Bug#25950).
* lisp/vc/ediff-diff.el (ediff-exec-process): Handle remote and quoted
file names.
* test/lisp/vc/ediff-diff-tests.el
(ediff-diff-tests--ediff-exec-process--quoted-file): Add unit test.
* lisp/emacs-lisp/cl-lib.el (cl--old-struct-type-of): New function.
(cl-old-struct-compat-mode): New minor mode.
* lisp/emacs-lisp/cl-macs.el (cl-defstruct): Pass `record' to
cl-struct-define to signal use of record objects.
* lisp/emacs-lisp/cl-preloaded.el (cl--struct-get-class,
cl-struct-define): Enable legacy defstruct compatibility.
* test/lisp/emacs-lisp/cl-lib-tests.el (cl-lib-old-struct,
old-struct): New tests.
* doc/lispref/elisp.texi, doc/lispref/records.texi: Document
`old-struct-compat'.
* lisp/url/url.el, lisp/url/url-cache.el, lisp/url/url-dav.el,
lisp/url/url-expand.el, lisp/url/url-file.el, lisp/url/url-imap.el,
lisp/url/url-ldap.el: Use `url-p' instead of `vectorp'.
* lisp/url/url-http.el (url-http): Check for type `url' instead of
`vector'.
* lisp/emacs-lisp/eieio-compat.el
(eieio--generic-static-object-generalizer): Adjust to new tags.
* lisp/emacs-lisp/eieio-core.el: Use records, and place the class object
directly as tag.
(eieio--object-class): Adjust to new tag representation.
(eieio-object-p): Rewrite, and adapt to new `type-of' behavior.
(eieio-defclass-internal): Use `make-record'.
(eieio--generic-generalizer): Adjust generalizer code accordingly.
* lisp/emacs-lisp/eieio.el (make-instance, clone): Use copy-record.
* lisp/emacs-lisp/pcase.el (pcase-mutually-exclusive-predicates):
Add `recordp'.
* doc/lispref/records.texi, doc/misc/eieio.texi: Update for records.
* lisp/emacs-lisp/cl-extra.el (cl--describe-class)
(cl--describe-class-slots): Use the new `type-of'.
* lisp/emacs-lisp/cl-generic.el (cl--generic-struct-tag): Use type-of.
(cl--generic-struct-specializers): Adjust to new tag.
* lisp/emacs-lisp/cl-macs.el (cl-defstruct): When type is nil, use records.
Use the type symbol as the tag. Use copy-record to copy structs.
(cl--defstruct-predicate): New function.
(cl--pcase-mutually-exclusive-p): Use it.
(cl-struct-sequence-type): Can now return `record'.
* lisp/emacs-lisp/cl-preloaded.el (cl--make-slot-desc): Adjust ad-hoc
code to new format.
(cl--struct-register-child): Work with records.
(cl-struct-define): Don't touch the tag's symbol-value and
symbol-function slots when we use the type as tag.

name if record's type holds class.
(Frecordp): New function.
(syms_of_data): defsubr it. Define `Qrecordp'.
(Faref, Faset): Work with records.
* src/fns.c (Flength): Work with records.
* src/lisp.h (prec_type): Add PVEC_RECORD.
(RECORDP, CHECK_RECORD, CHECK_RECORD_TYPE): New functions.

Fix a test that breaks the test suite when it is run within a
virtual environment.
See following link for details:
https://lists.gnu.org/archive/html/emacs-devel/2017-03/msg00857.html
* test/lisp/progmodes/python-tests.el
(python-shell-calculate-process-environment-7): Bind
python-shell-virtualenv-root to VIRTUAL_ENV when this var is set; otherwise
bind it to '/env'.
The original fix for Bug#6106 switched from signalling `search-failed'
to `user-error'. However, this breaks incremental searching over
multiple nodes because the isearch code doesn't expect a `user-error'.
* src/search.c (syms_of_search): New error, `user-search-failed',
with `user-error' and `search-failed' as parents.
* doc/lispref/errors.texi (Standard Errors): Document it.
* etc/NEWS: Announce it.
* lisp/info.el (Info-search): Use it instead of `user-error' so that
isearch will handle failed searches correctly.
Problem reported by Glenn Morris in:
http://lists.gnu.org/archive/html/emacs-devel/2017-04/msg00017.html
* test/Makefile.in (LOGFILES, TESTS): Omit leading "./".
(TESTS): Omit unnecessary patsubst.
(test_template): Redo dependency heuristic, hopefully
correctly this time. It's the .log file that depends,
not the phony test target. Declare the phonies to be PHONY.
Resurrect the exception for the *-tests subdirectory.
Adjust to the fact that leading "./" is omitted now.
