Update some URLs

2019-09-23T07:12:52+00:00

This mostly changes http: to https: in URLs.  It also updates
some URLs that have moved, removes some URLs that no longer
work, recommends against using procmail (procmail.org no
longer works), and removes some mentions of the
no-longer-existing Gmane, LPF and VTW.
It doesn't update all URLs, just the ones I had time for.
* GNUmakefile (help):
* admin/admin.el (manual-doctype-string):
* admin/charsets/Makefile.in (${charsetdir}/ALTERNATIVNYJ.map):
* admin/charsets/mapconv:
* lisp/net/soap-client.el (soap-create-envelope):
* lisp/org/org.el (org-doi-server-url):
* lisp/textmodes/bibtex.el (bibtex-generate-url-list):
Prefer https: to http: un URLs.

Make fingerprint handling compatible with LTO

2019-07-09T19:41:24+00:00

Tell the compiler that the fingerprint variable is modified unpredictably.

* lib/fingerprint.h (fingerprint): Remove const.
* lib/fingerprint.c (fingerprint): Likewise.
* src/pdumper.c (Fdump_emacs_portable): Cast fingerprint variable.
(pdumper_load): Likewise.
* lib-src/make-fingerprint.c (main): Likewise.

Port new fingerprinting scheme to clang + LTO

2019-05-04T20:16:15+00:00

* lib-src/make-fingerprint.c (main): Don't consider multiple
instances of the fingerprint to be an error, as this can
happen with clang and -flto.  Instead, replace all instances
of the fingerprint.  There is a tiny chance that this will
silently corrupt the Emacs executable.

This patch suggests that we should go back to fingerprinting
the inputs to the linker instead of its output, as the new
fingerprinting scheme is unnecessarily complicated and this
complexity reduces reliability. The old scheme (i.e., before
commit 2019-05-14T23:31:24Z!eggert@cs.ucla.edu) was simpler
and more portable and good enough, and it's looking like it
would be less trouble in practice than the new scheme.

Port make-fingerprint to LeakSanitizer

2019-04-21T06:10:57+00:00

* lib-src/make-fingerprint.c (buf): Now static,
to pacify LeakSanitizer.

* lib-src/make-fingerprint.c (main): Properly initialize 'prog'

2019-04-18T21:19:05+00:00

Fix make-fingerprint off-by-one bug

2019-04-18T19:57:47+00:00

Problem reported by Alex Gramiak in:
https://lists.gnu.org/r/emacs-devel/2019-04/msg00784.html
* lib-src/make-fingerprint.c (main): Fix recently-introduced
off-by-one bug when accessing args after -r.

Fix MS-Windows build broken by make-fingerprint changes

2019-04-15T14:17:01+00:00

* lib-src/make-fingerprint.c (fseeko) [WNDOWSNT]: Define to
fseeko64 for non-MinGW64 MinGW.

* lib-src/ntlib.c (stat): Fix calculation of file size.
(fstat): New function, a subset of src/w32.c:fstat.  This is
needed because make-fingerprint.c now calls 'fstat', and the
MS version will fail to produce reliable results because
nt/inc/sys/stat.h redefines 'struct stat'.
