Introducing pyNMS, SNMP, MIB and other tools for Python
by Keith Dart July 10, 2002

July 10, 2002

The pyNMS package is a collection of Python (and some C) modules for use in network management applications. It is also useful for testing and other types of applications. The package as a whole is currently in development, and much of the top-level NMS functionality (namely, a GUI interface). But, man low-level modules are still very useful for custom management scripts. Some notworthy sub-packages and modules: SNMP -- An implementation of SNMP v1 and v2c (Manager only now.. but Agent class just needs to be filled in). SMI -- A library, based on wrapping libsmi, for parsing and accessing MIB files. Devices -- Defines SNMP Manager objects for specific devices. You can create a class that represent as device, and define which MIBs it supports. POM -- Python Object Model for XML. This is patterned after XML DOM, but is more pythonic. It also incorporates some XPath funcionality. HTML -- Utilities and classes for creating XHTML documents. This is based on the POM module. This project is being hosted on Sourceforge. Home page: http://pynms.sourceforge.net/ Looking for feedback and testers. Have a Great day, Keith Dart

ANN: Logging Module v0.4.6 released
by vinay_sajip＠yahoo.co.uk July 7, 2002

July 7, 2002

A new version of the proposed Python standard logging module (as per PEP 282) has been released. What Does It Do? ================ The logging module offers the ability for any Python program to log events which occur during program execution. It's typically used to provide application diagnostics, warnings and error messages. In addition to capturing "what happened", "where it happened", "when it happened", "how important it is" and event specific data, you can configure, without changing the application source code, both the verbosity of logging and the routing of events to different destinations such as console, disk files, sockets, email addresses, Web servers, SOAP servers etc. etc. You can even change the configuration of a running program without stopping and restarting it! You can use the logging module in exception handlers, and it will include traceback information in the log. It's thread-safe, and very easy to use - just "import logging" and log away! Classes provided include: Logger - used to log messages for a particular area of an application. You can instantiate these wherever you want, there's no need to pass references to them around your application. You can log events based on importance levels of DEBUG (least important), INFO, WARN, ERROR, and CRITICAL (most important). You can define your own levels if the default levels don't meet your requirements. Handler - used to route events to particular destinations. Handlers included are: StreamHandler (for generalized streams, including console) FileHandler (for disk files - including log file rotation with size limits for log files) SocketHandler (for sending events to a TCP socket) DatagramHandler (for sending events to a UDP socket - faster, but less reliable than TCP) SMTPHandler (send events to arbitrary email addresses) HTTPHandler (send events to Web servers) SysLogHandler (send events to Unix syslog) MemoryHandler (batch up events and process them several at a time) NTEventLogHandler (send events to Windows NT event logs) There are also examples of XMLHandler and SOAPHandler in the distribution. Formatter - used to format events as text strings. Flexible "msg % arg_tuple" formatting is the basis for formatting, with flexible date/time formatting including ISO8601 and any strftime-based formats. Filter - used when filtering based on importance (DEBUG/INFO/WARN/ERROR/CRITICAL) is not sufficient. The distribution includes examples of filters based on class matching, regular expression matching, value matching, and logger matching. In the unlikely event that you're daunted by all the apparent complexity, fear not. The module offers a simple function-based interface to allow very simple, almost casual use of the underlying features. In addition to the core logging functionality, you get the ability to configure logging using a ConfigParser-based text file format, a Tkinter-based GUI configurator which creates configuration files for you, and a simple network-based event receiver which receives events on TCP, UDP, HTTP and SOAP ports. This is suitable for testing and might perhaps serve as a model for your own event receivers. Also included are over 20 test scripts which serve both as test harnesses and examples of how to use the logging module. You can get more information from http://www.red-dove.com/python_logging.html There are "download" and "recent changes" links at the top of that page. The new stuff includes some bug fixes, better support for class-based filtering and logging, more documentation of the configuration file format, an example hand-coded configuration file for those people who can't use the GUI configurator, an example Filter for regular-expression match-based filtering, and more! As always, your feedback is most welcome (especially bug reports, patches and suggestions for improvement). Enjoy! Cheers Vinay Sajip Red Dove Consultants Ltd. Changes since the last version: ================================= Added raiseExceptions to allow conditional propagation of exceptions which occur during handling. Added converter to Formatter to allow use of any function to convert time from seconds to a tuple. It still defaults to time.localtime but now you can also use time.gmtime. Added log_test22.py to test the conversion feature. Changed rootlogger default level to WARN - was DEBUG. Updated some docstrings. Moved import of threading to where thread is imported. If either is unavailable, threading support is off. Updated minor defects in python_logging.html. Check to see if ConfigParser has readfp method; if it does and an object with a 'read' method is passed in, assumes a file-like object and uses readfp to read it in.

spyce v1.1.22
by Rimon Barr July 7, 2002

July 7, 2002

Most important changes since last posting (v1.1.18) - easier install; .rpm should work on more systems - does not rely on mod_python by default... too hard to get right automatically, and users don't get to play with Spyce - downgraded some code to run on Python v2.1.1 and up. (requires nested scoping, so can't go further than that) - removed use of Python threads - new filter module - improved installation documentation, and explained how modules work ... and lots more. ---------- SPYCE - Server Python Pages SPYCE is a webserver plugin that supports simple and efficient Python-based dynamic HTML scripting. Those who like Python and are familiar with JSP, or PHP, or ASP, should have a look at this engine. It allows one to generate dynamic HTML content just as easily, using Python for the dynamic parts. Its modular design makes it very flexible and extensible. It supports FastCGI, CGI and mod_python to plugin into Apache and most other webservers. It can also be used as a command-line utility for HTML pre-processing. v1.1.22 released on 7 July 2002. Get it at: http://spyce.sourceforge.net ---------- Partial change log: v1.1.22 fixed Python v2.1.1-related bugs. improved installation process and documentation rpm more likely to succeed - uses fcgi or drops back to cgi no longer mod_python based by default v1.1.21 (faulty release) stochastic session clean up; no more threading dependency documentation: better installation notes peep-hole optimizer v1.1.20 (faulty release) created explicit (swappable) cache infrastructure BUG ** Spyce also works on Python v2.1 request - request.post(),post1() works in includes documentation: cheetah install, ... v1.1.19 filter module v1.1.18 fcgi support added X-Spyce header added documentation: how to write new modules v1.1.17 feature request - compaction algorithm improved ...

ANN: leo.py 2.5
by Edward K. Ream July 7, 2002

July 7, 2002

leo.py 2.5 is now available at: http://sourceforge.net/projects/leo/ The highlights of 2.5 --------------------- 1. Leo supports tab widths properly, and negative tab widths cause Leo to convert tabs to blanks as you type. Three new commands appear in the Edit Body menu: Convert Tabs, Convert All Tabs and Convert All Blanks. Convert All Tabs and Convert All Spaces convert the entire selected tree. 2. Leo now allows you to override selected preferences using a configuration file called leoConfig.txt. Leo acts as before if this file does not exist. An option in leoConfig.txt specifies whether leoConfig.txt is read-only. 3. The Preferences panel is now a modal dialog containing Ok, Cancel and Revert buttons. 4. At long last, cut and paste work properly in all situations. You can cut and paste between Leo and other applications, or between two different copies of Leo. 5. Added the Recent Files submenu to the File menu. 6. Fixed a number of bugs, including several crashers. Fixed several bugs in the Import commands. Leo will no longer abort reading if it detects an invalid directory name in the Default Tangle Directory in the Preferences panel. What is Leo? ------------ 1. A programmer's editor, an outlining editor and a flexible browser. 2. A literate programming tool, compatible with noweb and CWEB. 3. A data organizer and project manager. Leo provides multiple views projects within a single outline. 4. Fully scriptable using Python and saves its files in XML format. 5. Portable. leo.py is 100% pure Python and will run on any platform supporting Python and Tk/tcl. 6. Open Software, distributed under the Python License.

ANN: px/p4lib.py v0.6.6 - a p4 wrapper and a Python Perforce interface
by Trent Mick July 5, 2002

July 5, 2002

Where? http://starship.python.net/~tmick/ What are 'px' and 'p4lib.py'? Perforce is a source code control system (like CVS). One uses the p4 command line application (and/or a GUI client) to work with a Perforce repository. 'px' is a wrapper around p4. It provides all the functionality of p4 (defering work to it) plus it extends some standard p4 commands and adds a few new ones. If you are a Perforce user you might find these extensions useful. 'px' uses p4lib.py, a Python interface to the Perforce client application. If you are a Python programmer and script Perforce you might find this module helpful. Currently, most common commands (though your definition of "common" may differ from mine) are supported. What platforms? Windows and Linux. Cheers, Trent -- Trent Mick TrentM(a)ActiveState.com

ANN: 'which' v0.6.1 - A Python GNU-which replacement
by Trent Mick July 5, 2002

July 5, 2002

Where? http://starship.python.net/~tmick/ What is 'which'? GNU which is a common command line app on Unix. There are Windows ports (for example, the one in the Cygwin distribution), though I find the ones I have seen to be a little stupid. They don't understand the use of the PATHEXT environment variable. They don't support the useful '-a' option to listing all matches on the current PATH. This which has the following features: - it is portable (Windows, Linux); - it understands PATHEXT on Windows; - it can print all matches on the PATH; - it can note "near misses" on the PATH (e.g. files that match but may not, say, have execute permissions); and - it can be used as a Python module. What platforms? Windows and Linux. Cheers, Trent -- Trent Mick TrentM(a)ActiveState.com
