-### Commentary:
-
-# This file parses the file CaseFolding.txt in Unicode's UNIDATA package,
-# and generates a Lisp file containing instructions to set all the case
-# mappings in the standard case table.
-
-# To run this file, redirect its stdout to the file mule/uni-case-conv.el
-# (or whatever else you have named it according to the variable
-# `output_filename').
-
-# #### Aidan Kehoe, Do 9 Nov 2017 21:32:14 GMT; this approach doesn't work,
-# since CaseFolding folds both upper and lower case characters to lower case,
-# without marking which is which. We need to parse UnicodeData.txt instead; I
-# do this in lisp/mule/make-case-conv.el. I will remove make-case-conv.py down
-# the line.
-
-### Code:
-
-import urllib2, re, sys
-#import fileinput
-
-# The URL holding the case-folding table at www.unicode.org.
-uni_casefold_url = 'http://www.unicode.org/Public/UNIDATA/CaseFolding.txt'
-
-# Path to this file, as will appear in the comments of the generated file
-our_filepath = 'lib-src/make-case-conv.py'

-
-;;; Code:
-
-;; Hack: We nreverse the table below before applying it so that the more
-;; desirable mappings, which come early, override less desirable later ones.
-;; In particular, we definitely do not want the following bindings to work
-;; both ways:
-
-;; (?\u017F ?\u0073) ;; LATIN SMALL LETTER LONG S
-;; (?\u212A ?\u006B) ;; KELVIN SIGN
-;; (?\u212B ?\u00E5) ;; ANGSTROM SIGN
-
-;; The first two are especially bad as they will cause upcasing operations
-;; on lowercase s and k to give strange results. It's actually worse than
-;; that -- for unknown reasons, with the bad mappings in place, the byte-
-;; compiler produces broken code for some files, which results in a stack-
-;; underflow crash upon loadup in preparation for dumping.

Be more careful about integer types within the C code, e.g. not
using an int where a value represents a (possibly large) number of
bytes, or characters, especially relevant for values like fill
columns, which can usefully be set to most-positive-fixnum,
something the code up to now dealt with badly on a 64-bit build.
Issues flushed out using the -Wnarrowing GCC option.
* lisp.h (XCHAR_OR_CHAR_INT):
Provide an error-checking version of this to check uses with
fixnums where valid_ichar_p() is not true.
* lisp.h (GOOD_HASH):
Set this to a prime number just over 2^32 on sixty-four bit
architectures, of type Hashcode, an unsigned type, so modular
arithmetic is defined.

Summary: Better range checking, decoding Lisp values, for underlying C integer types
src/ChangeLog addition:
2018-04-21 Aidan Kehoe <kehoea(a)parhasard.net>
* data.c:
Provide macros to generalise the two-way conversion
between C integer types and Lisp values (fixnums, bignums, conses
of fixnums and, because GNU, floats).
Use these macros to generate conversion functions for OFF_T and
for uid_t. There may be scope down the line for further types, it
needs looking into.
* dired.c (Ffile_attributes):
Use OFF_T_to_lisp here.
* editfns.c:
* editfns.c (Ftemp_directory):
* editfns.c (Fuser_login_name):
* editfns.c (Fuser_uid):
* editfns.c (Fuser_real_uid):
Use lisp_to_uid_t, uid_t_to_lisp as appropriate in these
functions.
* fileio.c:
Remove the old lisp_to_off_t(). Use the new lisp_to_OFF_T.
* number.h:
Declare the new generated conversion functions for OFF_T and for
uid_t.
tests/ChangeLog addition:
2018-04-21 Aidan Kehoe <kehoea(a)parhasard.net>
* automated/os-tests.el (two-to-the-thirty-second):
Check that (user-login-name 4294967296) no longer gives "root", as
it used to do on 64-bit builds.

+
+ * data.c:
+ Provide macros to generalise the two-way conversion
+ between C integer types and Lisp values (fixnums, bignums, conses
+ of fixnums and, because GNU, floats).
+ Use these macros to generate conversion functions for OFF_T and
+ for uid_t. There may be scope down the line for further types, it
+ needs looking into.
+ * dired.c (Ffile_attributes):
+ Use OFF_T_to_lisp here.

+ * editfns.c (Ftemp_directory):
+ * editfns.c (Fuser_login_name):
+ * editfns.c (Fuser_uid):

+ Use lisp_to_uid_t, uid_t_to_lisp as appropriate in these

+ Remove the old lisp_to_off_t(). Use the new lisp_to_OFF_T.

Summary: Reduce narrowing warnings, catch non-idempotent arguments to make_integer()
src/ChangeLog addition:
2018-04-21 Aidan Kehoe <kehoea(a)parhasard.net>
* lisp.h (NUMBER_FITS_IN_A_FIXNUM, NUMBER_FITS_IN_A_FIXNUM):

If the GCC extended expression syntax is available, use it and
__typeof__ to catch non-idempotent arguments to these arguments,
and to silence type-narrowing warnings for non-EMACS_INT
arguments.

src/ChangeLog addition:
2018-04-21 Aidan Kehoe <kehoea(a)parhasard.net>
* gccache-x.c (gc_cache_hash):
* gccache-x.c (x_gc_cache_lookup):
Add a couple of casts here to placate the C++ compiler.
* text.c (rep_bytes_by_first_byte):
Don't use hexadecimal notation for 0xDEADBEEF in this table,
that causes a compile problem with C++ on a thirty-two bit
machine.

+ Don't use hexadecimal notation for 0xDEADBEEF in this table,

Summary: Quiet some compiler warnings, src/
src/ChangeLog addition:
2018-04-16 Aidan Kehoe <kehoea(a)parhasard.net>
* fileio.c (Finsert_file_contents_internal):
Be clearer about not using an unitialised OFFSET in an lseek(2)
call here.
* regex.c (re_wctype):
Match the argument types used in the declaration in regex.h, to
placate the C++ compiler.
* text.c:
Only make unicode_internal_handle_bad_ichar_to_unicode() available
on unicode-internal builds.
* tls.h (tls_negotiate):
Rework this stub macro to mark its arguments as used.
* vdb.c (Ftest_vdb):
Quiet the compiler regarding one variable here.

Summary: Handle bignum START, END values as appropriate, #'insert-file-contents-internal
src/ChangeLog addition:
2018-04-07 Aidan Kehoe <kehoea(a)parhasard.net>
* fileio.c (Fsubstitute_in_file_name): Fixup some whitespace here.
* fileio.c (Finsert_file_contents_internal):
Handle bignum values for START, END. Error if the difference
between START and END means the relevant buffer would become too
big to handle.
* insdel.c (buffer_insert_string_1):
Check the new buffer size in terms of characters, not bytes.
* lstream.c (make_filedesc_stream_1):
* lstream.c (make_filedesc_input_stream):
* lstream.c (make_filedesc_output_stream):
* lstream.h:
Use the OFF_T type for the OFFSET argument to these functions,
Bytecount for the COUNT argument, as has long been the most
reasonable approach.

Changeset: f101d3bd2814
User: kehoea
Date: 2018-04-10 07:03:42+00:00
Summary: Interpret a numeric APPEND as a position for lseek(), #'write-region-internal
src/ChangeLog addition:
2018-04-10 Aidan Kehoe <kehoea(a)parhasard.net>
* fileio.c (lisp_to_off_t): New function.
Decode a Lisp_Object into an OFF_T. Accept floats as well as
integers, as does GNU (they have more need to, because they don't
have bignums)
* fileio.c (Finsert_file_contents_internal):
Use it here.
* fileio.c (Fwrite_region_internal):
Interpret a numeric APPEND argument as specifying a byte offset in
the output file to seek to before writing.
lisp/ChangeLog addition:
2018-04-10 Aidan Kehoe <kehoea(a)parhasard.net>
* code-files.el (write-region):
Document that APPEND can now be a numeric offset, indicating a
point to seek to.
Affected #: 4 files

When called from a program, takes three required arguments:
START, END and FILENAME. START and END are buffer positions.
-APPEND, if non-nil, means append to existing file contents (if any), else
- the file's existing contents are replaced by the specified region.
+APPEND, if non-nil, means append to existing file contents (if any). If it is
+a byte file offset, seek to that point before writing.
VISIT, if non-nil, should be a string naming a file. The buffer is marked
as visiting VISIT. VISIT is also the file name to lock
and unlock for clash detection.
