This version fixes a few bugs in the way jSAVF implements the various unpacking algorithms needed to read the SAVF contents:
- The *LOW/SNA unpacking could in some cases produce too many bytes, which corrupted the extraction of SAVF embedded in other SAVF.
- The *MEDIMU/TERSE unpacking now handles many edge-cases in the way this algorithm dictionary behaves when full, which mostly happens on objects with high entropy such as programs or embedded SAVF, on which TERSE usualy gives negative compression ratios.
- The zlib unpacking which seems to be needed to open some SAVF since V7R5 is now supported.
This version offers a first shot at CSV export of database tables (members of non-source physical files). Most field types are handled except DECFLOAT which will probably come later. It's possible that some variants I have not tested may be incorrectly exported.
For now, I could export the following field types: NUMERIC, DECIMAL, TINYINT, SMALLINT, INTEGER, BIGINT, FLOAT, REAL, DOUBLE, DATE, TIME, TIMESTAMP, CHAR, BINARY, VARCHAR, VARBINARY, GRAPHIC, VARGRAPHIC, DBCS, CLOB, BLOB, DBCLOB
Given that the size and number of samples which I could find freely available on Internet is rather limited, it is probable that exporting large tables will be buggy (especially if they contain VARYING or LOB fields given the way these are stored when they do not fit their allocated space in the main record). More information can be obtained when enabling the debug/experimental mode in jSAVF preferences and restarting jSAVF.
I am considering making the CSV table export configurable to allow the selection of exported fields and their formatting, and to force their encoding.
This version also brings a first experimental shot at extracting *SOURCE or *LIST debug views which are included in some programs during compilation. This is available on objects of types *PGM, *MODULE and *SRVPGM when the debug/experimental mode is enabled at jSAVF startup.
For now the feature is quite basic, all debug views are exported together without further post-processing besides some unpacking when needed, so such exports may include the content of multiple source files or compilation spools.
If you encounter any issue with this version don't hesitate to reach out to me.
