* maint: clarify comments about sticky EOFPádraig Brady2018-06-241-1/+3
| | | | | | | | | * lib/af_alg.c: Be more direct that we can't assume stickiness of EOF for portability reasons. * lib/md5.c: Clarify that this isn't just a glibc issue. * lib/sha1.c: Likewise. * lib/sha256.c: Likewise. * lib/sha512.c: Likewise.
* af_alg: avoid hangs when reading from streamsPádraig Brady2018-06-241-6/+6
| | | | | | | | | * lib/af_alg.c (afalg_stream): Don't assume EOF is sticky, and thus avoid doing a fread() when feof() is set. * lib/md5.c: Ensure feof() is called before fread(). * lib/sha1.c: Likewise. * lib/sha256.c: Likewise. * lib/sha512.c: Likewise.
* crypto: use byteswapPaul Eggert2018-06-171-9/+2
| | | | | | | | | | * lib/md4.c, lib/md5.c, lib/sha1.c, lib/sha256.c, lib/sha512.c: * lib/sm3.c: Include <byteswap.h>. (SWAP): Use its macros rather than reinventing the wheel. * modules/crypto/md4, modules/crypto/md5-buffer: * modules/crypto/sha1-buffer, modules/crypto/sha256-buffer: * modules/crypto/sha512-buffer, modules/crypto/sm3: (Depends-on): Add byteswap.
* crypto: omit stream ops Emacs doesn’t needPaul Eggert2018-05-211-2/+5
| | | | | | | | | | | | | | | | | * lib/md5.c (md5_stream): * lib/sha1.c (sha1_stream): * lib/sha256.c (shaxxx_stream, sha256_stream, sha224_stream): * lib/sha512.c (shaxxx_stream, sha512_stream, sha384_stream): Compile stream functions only if GL_COMPILE_CRYPTO_STREAM is defined. Emacs needs this, as it does not use the stream operations and doesn’t need all the af_alg stuff we’ve recently added. Perhaps a similar change is needed to the other crypto modules, but this patch changes only those needed for Emacs. * modules/crypto/md5-buffer, modules/crypto/sha1-buffer: * modules/crypto/sha256-buffer, modules/crypto/sha512-buffer: New modules, used by Emacs. * modules/crypto/md5, modules/crypto/sha1, modules/crypto/sha256: * modules/crypto/sha512: Rewrite to depend on the new modules.

| | | | | | | | Problem reported by Assaf Gordon in: https://lists.gnu.org/r/bug-gnulib/2018-05/msg00041.html * lib/af_alg.c (afalg_buffer): Move local decls to pacify gcc -Wjump-misses-init. * lib/sha512.c (shaxxx_stream): Now static.
* crypto/{md5,sha1,sha256,sha512}: simplifyPaul Eggert2018-05-051-96/+26
| | | | | | | | | | | | | | * lib/md5.c (md5_stream): * lib/sha1.c (sha1_stream): * lib/sha256.c (shaxxx_stream): Simplify, partly by assuming C99. * lib/sha256.c (shaxxx_stream): New function, which implements both sha256 and sha224. Simplify, partly by assuming C99. (sha256_stream, sha224_stream): Use it to avoid code duplication, removing a FIXME. * lib/sha512.c (shaxxx_stream, sha512_stream, sha384_stream): Likewise.

* maint: Add encoding marker for Emacs to non-ASCII sources.Bruno Haible2018-01-051-0/+7
| | | | | | | | | | | | | | | | | | | Similar to commit f406941a8a2ec5fbf3eacc386b9be09d6593d53b from Paul Eggert <eggert@cs.ucla.edu> 2015-09-24. To determine the file list that need the marker, I used the command: for f in `find . -type f | grep -v '^\./\.git/' | grep -v '^\./tests/'`; do if iconv -f ASCII -t ASCII < $f > /dev/null 2>&1 ; then : ; else if iconv -f UTF-8 -t UTF-8 < $f > /dev/null 2>&1 ; then if grep 'The GNU C Library is' $f > /dev/null; then :; else if grep 'coding: utf-8' $f > /dev/null; then :; else echo $f fi fi fi fi done | LC_ALL=C sort

* digests, copy-file: increase the IO buffer size from 4KiB to 32KiBPádraig Brady2009-10-231-5/+20
| | | | | | | | | | | | | | | | | This results in a significant decrease in syscall overhead giving a 3% speedup to the digest utilities for example (when processing large files from cache).
