handling libs or the requests library
- Remove ldap_lib.py: This is now nicely supported by ldap3 which
also has a native iterator for paged search
- Remove Freshmeat.py: Freshmeat is more or less dead now and they
don't support an API-Test so it is very hard to get this right
- Put Firstname (with all the history) into its own package, note
that this needs more work to run against the latest version of the
website
- Lots of fixes for python3 compatibility: Where doctests existed
these pass now but there is still untested code and some code where
libaries are missing for python3 (pyst asterisk bindings and
openssl wrappers)

- Add ast_probe.py
- Allow specification of parsed config (cfg) for Call_Manager in
ast_call.py
- Better resource monitoring for asterisk and dahdi in ocf.py
- fix ocf.py to use new classes in isdn.py
- isdn.py now doesn't probe asterisk for the isdn stack in use if it
finds a hint in the config-file
Version 0.41: Minor feature enhancements
Fixes to Freshmeat, pycompat, sql-dump parser.
- Fix parsing of escaped quotes in mysql dumps
- Freshmeat
- pycompat fixes
Version 0.40: Distribution bug-fix
Renaming of README lead to the missing file README.rst in the distro.
Version 0.39: Minor feature enhancements
Fixes to hexdump, unicode issues (elementtree wrapper, stateparser).
Add some fixes to IP_Address comparison. The nmap output has changed in
recent versions, adapt to new format.
- Make address in hexdump configurable
- Bug-fix with comparison of sub-classes in IP_Address
- Unicode support in ETree
- Unicode support in stateparser
- Fix for trailing empty attributes in CSV output of PostgreSQL dumps
in sqlparser
- Unicode support in sqlparser (uses stateparser)
- Parse new nmap format
- Fix for configurable Releasetools location
Version 0.38: Minor feature enhancements
Fix boolean conversion of IP6_Address (and IP4_Address).
- IP6_Address would throw an error when trying a truth-test. Add
__nonzero__ (which always returns True even for the 0 Address)
Version 0.37: Minor feature enhancements
Change sort-order of IP_Address, make IP_Address immutable, use
metaclass magic to allow copy-constructor semantics.
- Sort order of IP_Address objects (both v4 and v6) now reverses the
order of the netmask: If the IP-Address part of the objects to
compare are the same, we used to sort by inverse netmask (putting
smaller networks with higher netmask first). We now reversed this to
be compatible with PostgrSQL cidr type objects.
- All attributes of IP_Address objects are now implemented as
properties to return the '_' variant of the attribute. Thus
IP_Address objects are (when using the public interface) immutable.
Since we already had a __hash__ method this effectively fixes the
interface to not allow mutation of objects that are in a dictionary.
- Allow calling the IP_Address constructors with another IP_Address
object. Since IP_Address objects are now immutable we use metaclass
trickery to return the passed object itself (instead of generating a
copy).
Version 0.36: Minor feature enhancements
Allow auto-coercion of comparison parameters. Add parent property and
is_sibling test.
- Now comparison operators and 'in' do auto coercion.
- Add parent property (next bigger network)
- Add is_sibling test (same parent)
Version 0.35: Minor feature enhancements
Add 'mask_len' as an alias of 'mask' to IP_Address.
- Need the network mask length (aka prefix length) sometimes as
mask_len (e.g. for FFM on github).
Version 0.34: Minor feature enhancements
Fix trafficshape to use new tc syntax. Add label to hexdump.
- The tc command has renamed the ipt action to xt (Linux
introduced xtables as a refactoring of iptables), the old ipt is
still available in iproute2 but we make xt the default now.
A backward-compatibility parameter can be used to get the old
behavior.
- Add save-mark to iptables action parser.
- The hexdump class now can generate labels.
Version 0.33: Minor feature enhancements
More fixes for ast_call.
- Add parser for events from asterisk wireshark trace
- Add fail.log for 'real' test
- Don't double-register call with Call_Manager
- Allow explicit matching by account-code
Version 0.32: Minor feature enhancements
More fixes for ast_call.
- Regression test with pyst asterisk emulator
- Fix case where OriginateResponse immediately returns Failure
- Tests for cases where Hangup comes before or after the
OriginateResponse
Version 0.31: Minor feature enhancements
Fix ast_call for immediately failing calls. Fix dahdi channel
computation in isdn.py.
- Fix OriginateResponse handling in ast_call
- Fix dahdi channel computation, can't directly use the span, use the
basechan attribute
Version 0.30: Minor feature enhancements
Fix how dahdi vs. mISDN interpret what is called an interface and what
is called a port. In mISDN we can combine several ports (physical lines)
to an interface. In dahdi both are the same (a port is a span in dahdi).
- Remove parsing of B- and C- channels from dahdi isdn parser
Version 0.29: Minor feature enhancements
The lcr module is now named isdn. It can now handle isdn interfaces
managed by Asterisk DAHDI in addition to Linux Call Router (LCR).
Version 0.28: Minor feature enhancements
Fix inductance formula of Robert Weaver, thanks Robert for pointing me
to the correction you did on your new site! For most doctests in the
inductance module the error was in the lower percentage points.
Add an xxrange iterator to the iter_recipes that can replace pythons
native xrange iterator but works with long integers. Needed for some
operations on IPv6 addresses in the IP_Address module.
- Fix inductance calculation according to patch from Robert Weaver
- Add xxrange iterator to iter_recipes
- Use new xxrange instead of xrange in IP_Address module, add a test
that failed with large numbers for IPv6
Version 0.27: Minor feature enhancements
Add pageurl and pageinfo attributes to HTML_Parser.Page_Tree, other
enhancements to HTML_Parser. Add pickle support to parser classes.
Fix comparison of IP_Address classes.
- Add pageurl and pageinfo attributes to HTML_Parser.Page_Tree storing
information retrieved via geturl and info calls from urllib2.
- Parser classes in stateparser.py and HTML_Parse.py where not
pickleable, fixed by removing parser-specific attributes when calling
pickle. Note that the parsing cannot be continued after reading class
from a pickle.
- Add base_pickler module to allow pickle exceptions
- HTML_Parse: Make Parse_Error a ValueError
- HTML_Parse: Raise line number with exception
- HTML_Parse: Add a timeout

Add sqlparser for parsing SQL dumps of PostgreSQL and mysql, add Phone
to parse phone numbers.
- sqlparser added
- Phone added for parsing phone numbers
Version 0.24: Minor feature enhancements
Better syntax checks and comparison operators for IP_Address, bug fixes
for parser and __str__ for IP_Address.IP6_Address
- IP_Address better syntax checks
- IP_Address __cmp__ and __eq__ improved for comparison with other types
- more regression tests for IP6_Address
- bug fixes in __str__ and parser of IP6_Address
- support for strict checking of netmask (all bits at right of netmask
must be zero if strict_mask is True)
Version 0.23: Minor feature enhancements
IP4_Address can now be put in a dict, add a subnets iterator for
IP4_Address. Factor IP_Address and add IP6_Address
- Add __hash__ for IP_Address
- The new subnets iterator for IP_Address iterates over all IPs in a
subnet. Optionally a netmask can be specified.
- Support for IPv6 addresses
- rename IP4_Address to IP_Address
Version 0.22: Minor feature enhancements
Allow unicode ip address input, hopefully make rsclib installable via pip.
- Address given to IP4_Address constructor now may be unicode
- Add download_url to setup.py to make installable via pip
Version 0.21: Minor feature enhancements
Fix autosuper: allow to inherit from non-autosuper classes, some small
fixes to ast_call and lcr parser. Fix ETree pretty-printing. Update
Freshmeat to new hostname. Add dotted netmaks parsing to IP4_Address.
- Since python2.6 constructor of "object" do not allow parameters, so
we need to strip these when doing the upcall from autosuper. This
fails when e.g. inheriting from a non-autosuper enabled class, e.g.,
class (With_Autosuper, dict)
in that case dict would get empty parameters. New implementation
finds out if our upcall is to "object", only in that case strip
parameters.
- ast_call now processes all queued unhandled events when a call is
matched.
- update regression test for ast_call.Call
- lcr parser: fix regex, port can have an empty name.
- Optimize call matching in ast_call: mark call as closed once we are
sure about the uniqueid. Add matching of Account-Code.
- Fix ETree pretty-printing: don't print unicode strings when arguments
are already converted
- freshmeat.net now is freecode.com (and the API redirects there),
update Freshmeat.py to new hostname (including .netrc credentials
with compatibility for old name).
- explicit mask paramter of IP4_Address can now be a dotted netmask.
Version 0.20: Not announced on freshmeat
Database value output for ast_cdr, added inductance calculation.
- ast_cdr: Add methods for database values of CDR records -- database
values of CDRs are different, they don't include start, end, answer
time-stamps but instead only a calldate, in addition the amaflags are
numerical in the database.
- added inductance calculation
Version 0.19: Not announced on freshmeat
Extend ETree with a walk method and implement small ldap library
- ETree: add walk method to walk the tree and call an optional pre- and
post-hook function
- ldap_lib: common ldap tasks for user and group search, and an
iterator for paged search (used with active directory).

Add a framework for process pipeline execution, processes can either be
python methods or external programs (with parameter list). They can be
connected in a pipe and there may be T-points in the pipe, where the
pipe forks into two or more pipelines fed by the output of one process.
- Add process pipeline framework
- HTML_Parse now has an explicit translate hook for preprocessing the
html page before parsing it. This defaults to the old behaviour of
filtering out common characters in broken HTML.
- Add nmap parser (e.g. to generate TeX tables from an nmap scan)
- Fix Lock_Mixin in execute module to remove lockfile at exit,
this used to rely on __del__ which breaks in certain cases.

Version 0.11: Not announced on freshmeat
Add a parser for CDR records in asterisk. We currently use text-files
only, this might be later extended for database use. Some fixes for
ast_call, make call-handling more robust (some race conditions would
identify events of other calls as belonging to our initiated call).
Add an execute module for executing commands and handling IO, this also
has a Lock and a Log mixin. Add ocf.py, a small framework for writing
OCF scripts for the heartbeat cluster resource manager (probably also
usable for the newer version called pacemaker but for now only tested
with the version in Debian stable aka lenny). Add lcr.py to model the
status of Linux Call Router ISDN lines.
