• The ast_call now is brought to latest version of pyst and asterisk
• isdn module now supports remote isdn via isdn gateway
• various python3 fixes

Version 0.55: LOCKDIR

• Now it's possible to set the locking directory (default is still /var/lock which is a symlink to /run/lock on modern systems) via the environment variable LOCKDIR.

Version 0.54: inductance, sqlparser

• The sqlparser now can do round-tripping (some items are in different order)
• More inductance formulae

Version 0.53: inductance, IPv4 address

• Change Rational to no longer print mixed fractions by default
• Allow setting the locking filename for Lock_Mixin in execute

Version 0.49: Python3 compatibility

• Remove ETree, HTML_Parse, PDF_Parse, multipart_form: These are better handled by libraries like BeautifulSoup or specific PDF 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)

Version 0.48: Fixes for execute

Version 0.45: Fix ISDN ports

String reprentation had leading unicode 'u'

• Fix string representation in ISDN ports

Version 0.44: Make line-waiting for bero configurable

For cluster resource berofos we make waiting for the L1 and L2 of the ISDN line configurable. The hard-coded default was too low.

• New config-item ISDN_WAIT_UP

Version 0.43: Support new berofos firmware

The new berofos (failover switch) firmware has some new low-level commands which we now accept when getting the device status.

• Fix bero.py to accept new low-level commands
• Add some more documentation to bero.py
• Add description of ast_probe in this README

Version 0.42: Feature enhancements

Add crm for pacemaker cluster management, new ast_probe for checking of asterisk status. Fixes to ocf and ast_call.

• 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.

• Fix MANIFEST.in

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
• HTML_Parse: raise Retries_Exceeded with url
• HTML_Parse: url parameter may now be None, not joined with site parameter
• Add pageurl and pageinfo to HTML_Parse
• IP_Address: Fix comparison
• Slight refactoring of NMAP_Parser class

Version 0.26: Minor feature enhancements

Fix double-utf-8-encoding option for sqlparser. Enhance stderr handling for exec_pipe.

• More detected broken encodings for fix_double_encode option
• execute.py: add error message from executed command to message raised by exec_pipe, make stderr output available in non-failing case.

Version 0.25: Minor feature enhancements

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).

Version 0.18: Not announced on freshmeat

Bugfix of ast_call and update for asterisk 1.6, small extension to IP4_Address.

• ast_call: match calls via (unique) account code
• ast_call: State vs ChannelState parameter in Newstate event
• ast_call: handle immediate error from asterisk (e.g. Permission Denied)
• IP4_Address: add netblk (start and end address for address with netmask)
