Revision 4.1.8a
---------------
- UNSTABLE ALPHA RELEASE.
- SMI/dispatcher timeout convertion multiplier is actually 100 (1/100 sec)
rather than 1/1000. This fix affects timeouts specified through SMI.
- __repr__() implemented for UdpTransportTarget, CommunityData, UsmUserData
in oneliner module.
- Automatically initialize table index values on table management
operations (SF bug ID #1671989).
- Fix to carrier code: ignore BADFD socket error as it may happen upon
FD closure on n-1 select() event.
- Fix to MibBuilder.setMibPath() to preserve previously loaded modules
intact. Otherwise loadModules() called after setMibPath() might fail
with 'MIB file not found in search path' exception.
- Fix to oneliner classes that now invoke unconfiguration methods on
destruction. This might have caused memory leaks.
- Automatically initialize SNMP-USER-BASED-SM-MIB::UsmUserSecurityName
columnar object instance on creation, as stated in DESCRIPTION (SF
tracker ID #1620392).
- Fix to USM timeframe arithmetics (SF bug #1649032).
- VACM shortcuts merged into universal add/delVacmUser() to let notifications
and requests to co-exist for the same user.
- At oneliners, build LCD tables keys from a hashed mix of input parameters
to make sure these automatic entries won't interfere or exceed constraints
on keys values.
- Made use of notificationType parameter of the sendNotification method
in NotificationGenerator applications. This parameter used to be
ignored in the past. Note, that previously used (and ignored) syntax
has been changed in an incompatible way.
- Allow plain Python values in setCmd() and sendNotification()
methods in CommandGenerator and NotificationGenerator applications
respectively.
- Multi-target oneliner API-based example script added.
- Ignore more socket errors in datagram-type async socket code.
- AES cipher now supported (rfc3826).
- Fix to messed up tagIDs of noSuchInstance and noSuchObject types.
- SET Command Responder fixed to obscure access to non-existing variables
by returning notWritable error (SF bug #1764839).
- AsynsockDispatcher.setSocketMap() method added to facilitate pysnmp
transport integration into third-party asyncore-based applications.
- Fix to errorIndex generation at CommandResponder application, the value
should be a one-based.
Revision 4.1.7a
---------------
- UNSTABLE ALPHA RELEASE.
- Low-level debugging facility implemented.
- Support UdpTransportTarget timeout and retries parameters in oneliner API.
- Fix to snmpTrapOID construction at ...proxy.rfc2576.v1ToV2()
function.
- Fix to MibViewController.getNodeName() to take MIB module name
into account (SF bug #1505847).
- Do explicit check for Counter32,Unsigned32,TimeTicks,Counter64 value types
in MibTableRow index convertion and in TextualConvention.prettyPrint()
methods (SF bug #1506341). Handle Bits in indices as RFC2578 suggests.
- Apply read-create column status to libsmi2pysnmp-generated code
whenever MIB text specifies that (SF bug #1508955).
- Honor and apply DISPLAY-HINT specification when building TextualConvention
class at libsmi2pysnmp.
- Managed Objects Instances files (smi/mibs/instances/) are now
double-underscore prefixed to make them imported explicitly by these
prefixed names. They used to be imported as a side-effect of
Managed Objects files import what is way too hackerish.
- The libsmi2pysnmp now supports future libsmi bugfix that would generate
"ranges" subtree along with the legacy and ambiguous "range" one.
- SMI support for fixed-length string indices implemented (SF bug #1584799,
#1653908).
- Managed Object Instances may now have smiRead, smiWrite, smiCreate methods
to support specific value mangling. These methods, if present, would be
invoked from SNMP [Agent] core instead of conventional clone() method.
The reason is to separate trivial value duplication from specific
Instance value mangling that may have Agent-specific side effects
(such as RowStatus).
- MIB table row destruction now works (SF bug #1555010).
- LCD unconfiguration functions for oneliners implemented (SF bug #1635270).
- unloadModules() and unexportSymbols() implemented at MibBuilder
- Notification type PDU proxy code fixed to produce symmetrical
convertion.
- Various SNMP engine-internal caches expiration implemented.
- SMI-level access control now takes effect only if AC object is
passed to MIB instrumentation API.
- LCD management code now uses generic MIB instrumentation features.
- Fix to oneliner manager code to have individual UdpSocketTransport
instance per each SnmpEngine. Multithreaded apps might fail otherwise.
(SF bug ID #1586420).
- Exclude the PYSNMP_MODULE_ID symbol from MIB view index, as it may get
resolved into OID label instead of actual MIB object name.
- Memory leak fixed in indices.OidOrderedDict implementation.
- Fix to VACM shortcuts to let notifications and requests to co-exist
for the same user otherwise.
- Fix to ...oneliner.cmdgen.UsmUserData to support non-default ciphers.
- USM now uses local notion of snmpEngineBoots/Time when authoritative
and cached estimate otherwise. Also, a security fix applied to to USM
time-window verification (SF bug #1649032).
- Fix to notification objects resolution code at
NotificationOriginator.sendNotification()
- Do not raise securityLevel for USM error reports that lacks user
information, as these reports could never be ciphered (SF bug #1624720).
- Non-default BULK PDU params now actually applied.
- SnmpEngineID default value generation algorithmic function changed
to allow multiple SNMP engines running on the same host.
- Documentation updated.
- A handful of minor fixes applied (SourceForge tracker IDs #1537592,
#1537600, #1537659, #1548208, #1560939, #1563715, #1575697, #1599220,
#1615077, #1615365, #1616579).
Revision 4.1.6a
---------------
- UNSTABLE ALPHA RELEASE.
- pysnmpUsmSecretAuthKey and pysnmpUsmSecretPrivKey length increased
up to 256 octets. There seems no limit on this in RFC, though.
- A workaround for probably broken Agents: SNMPv3 Manager code defaults
ContextEngineId to SecurityEngineId whenever ContextEngineId is not
reported by authoritative SNMP engine on discovery.
- Use empty PDU in engine-discovery report at mpmod/rfc3412.py.
- MibBuilder.loadModules() now fails on missing MIB files.
- MibBuilder.exportSymbols() now accepts unnamed objects (likely Managed
Objects Instances)
- SNMPv2-SMI.MibScalarInstance objects now support create*/destroy*
Management Instrumentation methods to pass Columnar Object creation and
removal events. MibTableColumn class invoke these methods accordingly.
- Fix to AsynNotificationOriginator.asyncSendNotification() callback
formal parameters
- Initial VACM configuration implemented according to rfc3415 Appendix 1
- tools/buildmibs.sh split-up and re-implemented as tools/build-pysnmp-mib
and pysnmp-mibs/tools/rebuild-pysnmp-mibs for better usability. These
and libsmi2pysnmp scripts made installable.
- Types/Notifications/Groups exportSymbols() call chunking implemented
in tools/libsmi2pysnmp
- Initial values specified to pyasn1 types to comply with latest pyasn1 API.
- Documentation improved
- Minor fixes towards Python 1.5 compatibility
Revision 4.1.5a
---------------
- UNSTABLE ALPHA RELEASE.
- Multi-lingual SNMP Trap/Inform Applications completed; examples added
- SMI model re-designed to make a clear separation between
Managed Objects and their specification (AKA Agent and Manager side)
- SNMP SET Application support completed
- Minor, though backward incompatible, changes to one-liner API
- Many bugfixes
Revision 4.1.4a
---------------
- UNSTABLE ALPHA RELEASE.
- SHA-based authentication fixed and privacy implemented
- ...oneliner.cmdgen.UsmUserData constructor now takes
authProtocol and privProtocol parameters in a backward incompatible
manner.
Revision 4.1.3a
---------------
- UNSTABLE ALPHA RELEASE.
- rfc3413 applications API changes (related to callback function
behaviour).
- TransportDispatcher now provides "jobs" interface to clients
for better control of dispatcher's execution.
- Many minor fixes.
Revision 4.1.2a
---------------
- UNSTABLE ALPHA RELEASE.
- Top-level application classes renamed into longer, self descripting names
for clarity.
- CommandResponder & NotificationOriginator applications now uses
stand-alone SnmpContext for application registration.
- Many minor fixes (inspired by testing on WinXP)
Revision 4.1.1a
---------------
- UNSTABLE ALPHA RELEASE.
- SNMPv3 code first published
- SNMP engine and applications implemented on library level
- Major re-design towards SNMPv3-style API.
Release 4.0.2a
--------------
- Adopted to slightly changed asyncore API (as shipped with python 2,4)
Release 4.0.1a
--------------
- Minor bug/typo fixes, mostly in example/ scripts.
Release 4.0.0a
--------------
- UNSTABLE EARLY ALPHA RELEASE.
- Major re-design and re-implementation.
- Rudimental API versioning implemented to let incompatible package
branches to co-exist within the same Python installation.
- SMI framework designed and implemented. This framework provides
1) various access to MIB data 2) a way to implement custom MIB
instrumentation objects. There's also a tool for building SMI classes
from libsmi(3) output (smidump -f python).
- ASN.1 subtyping machinery implemented. Now dynamic ASN.1 instances
subtyping and quering becomes available. Previously, this has been done
through Python classes inheritance what proved to be a wrong concept.
- ASN.1 codecs framework re-designed and re-implemented aimed at a more
consistent design and better performance. Highlights include abstract
codec interface and serialized data caching (at encoder).
- Asn1Item constraints machinery re-implemented based on Mike C. Fletcher's
design and code. Now various constrains are implemented as stand-alone
objects serving interested Asn1Object derivatives through some abstract
protocol (that's probably the Decorator design pattern).
- ASN.1 tagging facility re-implemented along the client-server design
pattern. Besides this seems to be a more appropriate design, it allows
an easier way for dynamic subtyping.
