October 7, 2007 |
Bug fixes.
|
| 0.9.0 |
August 25, 2007 |
Major overhaul of osh.
- Removed the concept of named streams. They were only used to have separate output and error streams,
and error streams were awkward to use, different in the CLI and API, and a mess internally. The 'o'
stream is still present, but not named. It's just the one stream that carries objects from one
command to the next. Exceptions and stderr output are handled by functions, which can be replaced
by the user. Default implementations print to stderr.
- Cleanup of module names, following introduction of package structure in version 0.8.0.
E.g., osh.oshapi has been renamed osh.api.
- Complete rewrite of documentation. Command-line help and reference manual
are both derived from module and function __doc__ strings. The reference manual is
generated using epydoc.
Other changes:
- gen command has new flag, -p, to format generated integers as 0-padded strings.

| 0.8.1 |
April 15, 2007 |
- Added cat command.
- Improvements in error handling, especially remote errors.
|
| 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.

| 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).
|
| 0.7.0 |
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.

|
| 0.6.0 |
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.

October 25, 2005 |
Cleanup for first public release. Added timer command, process objects and the
processes function.
|
| 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.
|
| 0.3 |
May 2005 |
Added remote execution syntax and commands (@, [...], install, installosh, copyfrom, copyto).
|
| 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.
|
| 0.1 |
October 2004 |
Each osh command ran as a separate process. Pickling was used to transmit objects between commands.
