Added

• Docker support.
• (Experimental) ExecuteFunction support.
• (Experimental) Proxyless Gateway support.
• ExecuteQuery support for types and namespaces.
• JSON serialization for interoperability (also Repr, Pickle and Dill).
• Saving context now saves user functions.
• Python datatypes escaper: string, bool, date, time, timestamp.
• Initializer interface.
• Python shell: do ##class(isc.py.util.Shell).Shell()
• Business Process emulator.
• Sample %ZLANGC00 and %ZSTART routines.

Changed

• Dill is now a required module.
• GetVariableInfo now returns FQCN as type.
• GetVariableInfo support for attributes (methods and the like).
• Test process now uses non-interactive GUI for test business process
• Test process: new data, simplified code.
• Log trace events enabled by default.

Removed

• Test methods GetRandom, GetRandomSimple, SimpleStringFull from callout API

Installation instructions

See README.md

Update instructions (from v0.6):

1. Load new code and library.
2. PythonLib setting should be reset again if it was set before the update.
3. All processes using RAW data ingestion method must be recompiled.
4. It's now a requirement to install dill module: pip install dill.
5. Reload test data: do ##class(isc.py.test.CannibalizationData).Import()

Mac OS X support

New features:

• Queries - load data from query without xDBC
• Linux - added ability to load Python library explicitly
• Test process now works in 3 modes: RAW, ODBC, JDBC
• Mac OS X support
• Added exception handling to Callout interface
• Added Main interface utility methods

Streams support

Streams up to 2,147,483,647 bytes (~2Gb) now can be passed inside to python context and retrieved (up to IRIS limit) from it.
Context persistence uses streams.
New class isc.py.Main as a public interface.
Mask and MaxLength conditions added to context persistence.

Stream length also depends on available process memory, so real limits may be lower.

Pass limit raized to 3 641 144 characters, context persistence, error reporting

Now it works!

Both input and output are now limited to 3 641 144 characters which is a maximum for callout library.
Context now can be persisted, displayed and restored. See readme for details.
Get errors with set sc = ##class(isc.py.Callout).GetStatus()
Refactored interoperability messages. All processes now must utilize the new request and response classes instead of the old ones:

• isc.py.ens.Request → isc.py.msg.ExecutionRequest
• isc.py.ens.Response → isc.py.msg.ExecutionResponse
