This change is required to the change in Libgcrypt. Note that we will
likely use a different OpenPGP algorithm ID for EdDSA and thus the
current Ed25519 implementation will not stay with us.

This is a more general fix for the nested compression packet bug. In

Beware: This code has not been tested because it is not yet possible
to build GnuPG 2.1 for Windows. However, the code will be the base
for an implementation in 2.0.
A portable use of GnuPG under Windows means that GnuPG uses a home
directory depending on the location of the actual binary. No registry
variables are considered. The portable mode is enabled if in the
installation directory of the the binary "gpgconf.exe" and a
file "gpgconf.ctl" are found. The latter file is empty or consists
only of empty or '#' comment lines.

It is often time consuming to figure out whether still allocated
memory at process termination is fine (e.g. a cache) or a problem. To
help for that register_mem_cleanup_func may now be used to cleanup
such memory. The run time of the program will be longer; if that
turns out to be a problem we can change the code to only run in
debugging mode.

--
Gpg uses the key database at several places without a central
coordination. This leads to several scans of the keybox for the same
key. To improve that we now use a simple cache to store a retrieved
keyblock in certain cases. In theory this caching could also be done
for old keyrings, but it is a bit more work and questionable whether
it is needed; the keybox scheme is anyway much faster than keyrings.
Using a keybox with 20000 384 bit ECDSA/ECHD keypairs and a 252 byte
sample text we get these values for encrypt and decrypt operations on
an Core i5 4*3.33Ghz system. The option --trust-model=always is used.
Times are given in milliseconds wall time.
| | enc | dec | dec,q |
|-----------+-----+-----+-------|
| key 1 | 48 | 96 | 70 |
| key 10000 | 60 | 98 | 80 |
| key 20000 | 69 | 106 | 88 |
| 10 keys | 540 | 290 | 70 |
The 10 keys test uses a mix of keys, the first one is used for
decryption but all keys are looked up so that information about are
printed. The last column gives decryption results w/o information
printing (--quiet).
The keybox is always scanned sequentially without using any index. By
adding an index to the keybox it will be possible to further reduce
the time required for keys stored to the end of the file.
* common/logging.c (log_clock): New.
* g10/gpg.c (set_debug): Print clock debug flag.
* g10/options.h (DBG_CLOCK_VALUE, DBG_CLOCK): New.
--
To actually use log_clock you need to enable the code in
logginc.c:log_check() and link against librt. --debug 4096 may then
be used to enable it at runtime.
* common/argparse.c (iio_item_def_s, IIO_ITEM_DEF): New.
(initialize): Init field IIO_LIST.
(ignore_invalid_option_p): New.
(ignore_invalid_option_add): New.
(ignore_invalid_option_clear): New.
(optfile_parse): Implement meta option.
--
This option is currently of no use. However, as soon as it has been
deployed in all stable versions of GnuPG, it will allow the use of the
same configuration file with an old and a new version of GnuPG. For
example: If a new version implements the option "foobar", and a user
uses it in gpg.conf, an old version of gpg would bail out with the
error "invalid option". To avoid that the following line can be put
above that option in gpg.conf
ignore-invalid-option foobar
This meta option may be given several times or several option names
may be given as arguments (space delimited). Note that this option is
not available on the command line.

The 3 standard curves are now supported in gpg-agent's ssh-agent
protocol implementation. I tested this with all 3 curves and keys
generated by OpenSSH 5.9p1.
Using existing non-ssh generated keys will likely fail for now. To fix
this, the code should first undergo some more cleanup; then the fixes
are pretty straightforward. And yes, the data structures are way too
complicated.
* configure.ac (HAVE_BROKEN_TTYNAME): New ac_define set for Android
systems.
* common/util.h (gnupg_ttyname): New macro. Change all callers of
ttyname to use this macro instead.
(ttyname) [W32]: Rename to _gnupg_ttyname and use also if
HAVE_BROKEN_TTYNAME is defined.
* common/simple-pwquery.c (agent_send_all_options): Keep on using
ttyname unless HAVE_BROKEN_TTYNAME is set. This is because this file
may be used standalone.
The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems. We now use two \x27 characters ('...').
The proper solution would be to use the correct Unicode symmetric
quotes here. However this has the disadvantage that the system
requires Unicode support. We don't want that today. If Unicode is
available a generated po file can be used to output proper quotes. A
simple sed script like the one used for en@quote is sufficient to
change them.
The changes have been done by applying
sed -i "s/\`\([^'\`]*\)'/'\1'/g"
to most files and fixing obvious problems by hand. The msgid strings in
the po files were fixed with a similar command.
* g10/keygen.c (keygen_set_std_prefs): Include IDEA only in PGP2
compatibility mode.
* g10/misc.c (idea_cipher_warn): Remove. Also remove all callers.
* common/status.h (STATUS_RSA_OR_IDEA): Remove. Do not emit this
status anymore.
--
To keep the number of actually used algorithms low, we want to support
IDEA only in a basically read-only way (unless --pgp2 is used during
key generation). It does not make sense to suggest the use of this
old 64 bit blocksize algorithm. However, there is old data available
where it might be helpful to have IDEA available.
* common/Makefile.am (CLEANFILES): Rename to MAINTAINERCLEANFILES.
--
In general this is not required because automake does this for files
in BUILT_SOURCES anyway. However, having them in CLEANFILES is wrong.
This is bug#1398.
GnuPG requires that options are given before other arguments. This
can sometimes be confusing. We now print a warning if we found an
argument looking alike a long option without being preceded by the
stop option. This is bug#1343.

For the shared code parts it is cumbersome to pass an error sourse
variable to each function. Its value is always a constant for a given
binary and thus a global variable makes things a lot easier than the
former macro stuff.

DEFAULT_ERRSOURCE.
* common/init.h: Assert value of GPG_ERR_SOURCE_DEFAULT.

(_ESTREAM_PRINTF_FREE): Remove.
(_ESTREAM_PRINTF_REALLOC): New.
(fixed_realloc) [!_ESTREAM_PRINTF_REALLOC]): New.
(estream_vasprintf): Use my_printf_realloc instead of my_printf_malloc
and my_printf_free.
(dynamic_buffer_out): Use my_printf_realloc instead of realloc.

This bug will never happen in current GnuPG/Libgcrypt because we use
the standard memory allocation functions via Libgcrypt. However, when
used in other environments it would mess up the heap for an asprintf
with an output length larger than ~512 bytes.
This change might help to c+p a fingerprint from an HTML page without
being enclosed in a "pre" tag.
* common/userids.c (classify_user_id): Skip a second blank in the
middle of a fingerprint.
* common/dotlock.c (use_hardlinks_p, dotlock_take_unix): Check return
value of link().
* g13/g13.c: Make sure err is initialized.
