a window when the new patch file wasn't committed, and there's no check
for "extra" lines in distinfo, so this clearly identifies the version
with the new patch file included.
After spending more time on this this trying to patch it properly than I
care to admit, I concede defeat and add a hack.mk for DragonFly.
I'm not exactly sure what the problem is, other than "make" works on the
subdir makefile and "bmake" doesn't. And that's only true if executed
outside of the package -- hardcoding "make" inside the do-build phase
doesn't work. Weird problem, but the hack works.
* Added support for retrieving Sieve scripts from dict lookup. This
means that Sieve scripts can now be downloaded from a database.
Compiled script binaries are still put on disk somewhere if used.
The INSTALL documentation is updated with information on this new
feature and the (backwards-compatible) changes to the configuration.
Note that his feature is currently not supported for
sieve_before/sieve_after or script management through ManageSieve.
+ Incorporated the sieve_duplicate plugin into main Pigeonhole tree as
a normal extension (vnd.dovecot.duplicate). This Dovecot-specific
extension adds the ability to check for duplicate deliveries based
on message ID. Specification can be found in:
doc/rfc/spec-bosch-sieve-duplicate.txt
+ Added support for specifying multiple sieve_before and sieve_after
paths. This adds much more flexibility to the multiscript
configuration. One application is to have user-specific Sieve
scripts outside the user's normal control through ManageSieve.
+ Added a "session ID" string for managesieve connections, available in
%{session} variable (analogous to Dovecot change).

This source and binary release contains minor fixes to the
unannounced 2010-02-02 release. It is the first official

This source and binary release cleans up a few reported
build problems in the 2009-05-01 release (which has been
removed). The release procedures have been adjusted to avoid
similar problems in the future. (The main problem is
synthesizing external non-ast environments to fully exercise
portions of the build system seen by outside users -- since
we use our stuff for everything, including packaging and
building, setting up an environment that has no ast
components leaking in can be non-trivial).
See the release change log for details:
http://www2.research.att.com/~gsf/download/release.2009-05-05.2009-05-01.html
2009-05-01
This source release contains the official (and hopefully
final) ksh93t+ 2009-05-01, along with updates for the ast
commands and libraries. A lot of work went into cleaning up
the regression tests -- most regressions directly correspond
to unsupported native system features or buggy native system
interfaces that we felt should be fixed rather than worked around.
Of course we could be persuaded otherwise.

Yes -- a new release in only 3 months. This release contains
fixes and features that address the issues raised on the lists.
A summary of recent ksh93 changes:
1. Double precision floating point arithmetic with full C99
arithmetic support on systems that provide the C99
arithmetic functions. The numbers Inf and NaN can be
used in arithmetic expressions.
2. TAB-TAB completion generates a numbered list of
completions which the user can select.
3. Support for processing/handling multibyte locales (e.g.,
en_US.UTF-8, hi_IN.UTF-8, ja_JP.eucJP, zh_CN.GB18030,
zh_TW.BIG5 etc.) has been extensively revised, tested,
and is now supported even on the language level (e.g.
variable and function identifiers may contain locale
specific codeset characters).
4. /dev/(tcp|udp|sctp)/host/sevrice now handles IPv6
addresses on systems that provide getaddrinfo(3).
5. The ability to seek on a file by offset or content with
new redirection operators.
6. A new --showme option which allows portions of a script
to behave as if -x were specified while other parts
execute as usual. This simplifies the coding of make -n
style semantics at the script level by eliminating code
replication. In particular, io redirections are handled
by --showme.
7. The [[...]] operator =~ has been added which compares
the string to an extended regular expression rather than
== which compares against a shell pattern.
8. The printf(1) builtin has been extended to support the =
flag for centering a field. The # flag when used with
%d and %i provides values in units of thousands or 1024
respectively with an appropriate suffix added.
9. Example screenshots from joint work with the Solaris
ksh93 integration project are available here.

This release, almost a year from the last big release,
contains changes based on feedback from the { ast-users
ast-developers uwin-users uwin-developers } lists and the
ongoing ksh93-solaris integration project. Thanks to all

frequency to keep internal and external source/binaries
more in sync. See the release change log for details:

This isn't strictly true; foolscap needs to be >= 0.6.3 if Twisted is
> 10, but it's easier to just require it than invent new compound
dependencies.
PKGREVISION++, because tahoe-lafs built with Twisted > 10 and foolscap
0.6.1 (from today or earlier in pkgsrc) fails to work.
pkgsrc.
* Release 0.6.3 (05-Jan-2012)
** Compatibility Fixes
This release really is compatible with Twisted-11.1.0 . The previous Foolscap
release (0.6.2), despite the changes described below, suffered mild
incompatibilites with the new TLS code in the final Twisted-11.1.0 release.
The most common symptom is a DirtyReactorError in unit tests that use
Tub.stopService() in their tearDown() method (to coordinate shutdown and
cleanup). Another symptom is tests overlapping with one another, causing
port-already-in-use errors.
This incompatibility did not generally affect normal operation, but only
impacted unit tests.
** Other Changes
The Debian packaging tools in misc/ were removed, as they were pretty stale.
These days, both Debian and Ubuntu make their own Foolscap packages.
* Release 0.6.2 (15-Oct-2011)
** Compatibility Fixes
Foolscap-0.6.2 will be compatible with future versions of Twisted (>11.0.0).
The 0.6.1 release will not: a TLS change went into Twisted trunk recently
(after the 11.0.0 release) which broke Foolscap 0.6.1 and earlier.
This release also fixes a minor incompatibility with newer versions of
OpenSSL (0.9.8o was ok, 1.0.0d was not), which caused errors in the test
suite (but normal runtime operation) on e.g. Ubuntu 11.10 "Oneiric".
** Git-Over-Foolscap Tools
The doc/examples/ directory contains two executables (git-foolscap and
git-remote-pb) which, when placed in your $PATH, make it easy to use Foolscap
to access a Git repository. These use the flappserver/flappclient tools and
let you build a FURL that provides read-only or read-write access to a single
repository. This is somewhat like providing SSH access to a repo, but with a
much smaller scope: the client will only be able to manipulate the one
repository, and gets no other authority on the target system. See the tool's
inline comments for usage instructions.
** Minor Fixes
Using 'flappserver upload-file FILE1 FILE2 FILE3..' (with three or more
files) now correctly uploads all files: previously it only managed to upload
the first and last.
'flappserver' argument handling was improved slightly. A workaround was added
to handle a Twisted stdio-closing bug which affected flappserver's
run-command function and broke the git-foolscap tool. Several changes were
made for the benefit of Windows: log filenames all use hyphens (not colons),
log filtering tools tolerate the lack of atomic-rename filesystem operations,
and some unixisms in the test suite were removed.
The Tub.setLogGathererFURL() method can now accept a list (iterable) of log
gatherer FURLs, not just a single one.
For some reason, LLVM is using autoconf files from 2003 which is before
DragonFly even existed. I submitted a bug report #12944 at llvm.org's
bugzilla to request they use versions from 2012.
Also, installation fails at document generation without some extra tools.
No need to revbump, either built or it didn't without these packages.

* [CVE-2012-2417] Fix LP#985164: insecure ElGamal key generation.
(thanks: Legrandin)
In the ElGamal schemes (for both encryption and signatures), g is
supposed to be the generator of the entire Z^*_p group. However, in
PyCrypto 2.5 and earlier, g is more simply the generator of a random
sub-group of Z^*_p.
The result is that the signature space (when the key is used for
signing) or the public key space (when the key is used for encryption)
may be greatly reduced from its expected size of log(p) bits, possibly
down to 1 bit (the worst case if the order of g is 2).
While it has not been confirmed, it has also been suggested that an
attacker might be able to use this fact to determine the private key.
Anyone using ElGamal keys should generate new keys as soon as practical.
Any additional information about this bug will be tracked at
https://bugs.launchpad.net/pycrypto/+bug/985164
* Huge documentation cleanup (thanks: Legrandin).
* Added more tests, including test vectors from NIST 800-38A
(thanks: Legrandin)
* Remove broken MODE_PGP, which never actually worked properly.
A new mode, MODE_OPENPGP, has been added for people wishing to write
OpenPGP implementations. Note that this does not implement the full
OpenPGP specification, only the "OpenPGP CFB mode" part of that
specification.

* Fix: getPrime with invalid input causes Python to abort with fatal error
https://bugs.launchpad.net/pycrypto/+bug/988431

Changes 1.7.27:
* Increased row_buf malloc to row_bytes+64 instead of row_bytes+16, to
match the size of big_row_buf in pngrutil.c (it is 48 in libpng14, 15, 16,
and 64 in libpng10, 12. Otherwise there is a double-free crash when the
row_buf is destroyed.
Changes 1.7.26:
* Increased the text_text buffer from 2048 to 10*2048 (Ralph Giles), and
changed an incorrect test for keyword length "< 180" to "< 80". The
text_text buffer was inadvertently reduced from 20480 to 2048 in
pngcrush-1.7.9.
* Added -DZ_SOLO to CFLAGS, needed to compile zlib-1.2.6.
* Changed user limits to width and height max 500000, malloc max 2MB,
cache max 500.
* Added -nolimits option which sets the user limits to the default
unlimited values.
