| 0.1 |
October 2004 |
Each osh command ran as a separate process. Pickling was used to transmit objects between commands.
|
| 0.2 |
December 2004 |
Complete rewrite. Introduced piping of objects internal to python process, denoted by '^'.
Everything after "osh" on the command line is concatenated into a single string
which is then parsed. Introduced tpg parser to parse command line.
|
| 0.3 |
May 2005 |
Added remote execution syntax and commands (@, [...], install, installosh, copyfrom, copyto).
|
| 0.4 |
September 8, 2005 |
Lots of polishing and bug-fixing based on day-to-day usage in helping to develop
the Archivas cluster, ArC.
|
| 0.5 |
October 25, 2005 |
Cleanup for first public release. Added timer command, process objects and the
processes function.
|
| 0.6.0 |
October 31, 2005 |
Cleaner integration with Python functions. Previously, functions in f, select, etc.
received a single argument, typically a tuple or list, and elements were obtained
by subscripting.
Now, the elements of
an incoming tuple or list are assigned to arguments. (If you want
to use a tuple argument, then prefix the argument declaration with '*', just
as in ordinary Python.) Also deleted spread command, replacing it with expand, which
is more general.

November 15, 2005 |

|
| 0.6.2 |
December 15, 2005 |
Bugfix release. Fixed a number of bugs in the squish command.
|
| 0.6.3 |
February 15, 2006 |
Bugfix and minor feature release. Fixed error handler to not
propagate errors downstream.
Added -t option to out.
Much improved ctrl-c handling.
|
| 0.7.0 |
April 26, 2006 |
Major upgrade:
- Added an API: osh can now be used from within Python.
- Nodes of cluster can be configured as a list of addresses as before; or as a map in which the key is a logical
name and the value is the address.
- Generalized expand command.
- Modified options of window command.
|
| 0.7.1 |
October 5, 2006 |
- oshtestssh is now much faster. It checks all nodes in parallel.
- Fixed bugs and error reporting in the sql command.
- Cluster configuration can now specify a default database for each node of the cluster, (see documentation for sql command).
|
| 0.8.0 |
January 8, 2007 |
- Restructured so that top-level modules are in the osh package.
- Osh configuration file now supports slice notation, (e.g. osh.remote['cluster-123'].user = 'root').
- Added version command.
- Added imp command.
- Added py command.
- oshapi errors are now reported as exceptions, not output on e stream.
Better fit for a python script. This also enables osh() to return o stream output in a list.
- New oshapi command, return_list() to return o stream output in a list. Most uses of oshapi
no longer need to handle o and e stream outputs via handlers.
- Improvements in error handling, especially remote errors.
