abap gzip zip

[Former Member]

Hi,

I have tried to use the classes,

cl_abap_zip

CL_ABAP_GZIP

CL_ABAP_GZIP_BINARY_STREAM

CL_ABAP_UNGZIP_BINARY_STREAM

I use winzip 8.1 sr1

SAP XI SP14

status report

cl_abap_zip - fails to read a file created with winzip

cl_abap_zip - can create a file that may be opened with winzip

cl_abap_zip can zip and then unzip the just zipped data, it is COMPATIBLE WITH ITSELF

CL_ABAP_GZIP - can not read files created with gnu gzip, nor write files that can be read with gnu gzip

CL_ABAP_GZIP - can gzip and then ungzip the just gzipped data, it is COMPATIBLE WITH ITSELF

CL_ABAP_GZIP_BINARY_STREAM CL_ABAP_UNGZIP_BINARY_STREAM both hangs when trying to use the _end method

I'm using gui_upload and gui_download to create the files, which works fine, except for big files, this is why you want to use compression.

If someone has useful working examples, that would be appreciated.

Sap was creating gzip without header info. Please check SAP Note 2475108 for fix.

Here is an abap implementation of gzip / gunzip. Enjoy.

If you find it useful, please post a followup. The same goes if you find bugs, or make any improvements. As usual without any warranty, use at your own risk.

It is useful when you need to upload hughe file with gui_upload.
