[2/2] incubator-corinthia git commit: Added functions to work
directly with zlib.
Posted by ja...@apache.org.
Added functions to work directly with zlib.
Minizip is removed, a.o. due to its problematic license in the main part of corinthia.
New functions have been made, with significant differences:
DFZipOpen, now scans the zip file, and delivers the whole directory back.
DFZipReadFile, reads the whole file in one chunk, and delivers a freshly allocated buffer back
DFZipCreate, creates a new zip file without knowing the content
DFZipWriteFile, adds a whole file to the zip file, and updates the in memory directory.
DFZipClose, releases used memory, and in case of creating a zip file, writes the global directory as well as the end record.
The functions have been tested with LO, AOO, MS-WORD on ODF and OOXML files. The testing showed an error in AOO ODF implementation,
AOO has significant differences between the local header and the global directory, making it very difficult to recover a file with
a corrupted directory. The functions accepts the behaivour of all 6 combinations.

- This code is a modified version of crypting code in Infozip distribution
-
- The encryption/decryption parts of this source code (as opposed to the
- non-echoing password parts) were originally written in Europe. The
- whole source package can be freely distributed, including from the USA.
- (Prior to January 2000, re-export from the US was a violation of US law.)
-
- This encryption code is a direct transcription of the algorithm from
- Roger Schlafly, described by Phil Katz in the file appnote.txt. This
- file (appnote.txt) is distributed with the PKZIP program (even in the
- version without encryption capabilities).
-
- If you don't need crypting in your application, just define symbols
- NOCRYPT and NOUNCRYPT.
-
- This code support the "Traditional PKWARE Encryption".
-
- The new AES encryption added on Zip format by Winzip (see the page
- http://www.winzip.com/aes_info.htm ) and PKWare PKZip 5.x Strong
- Encryption is not supported.
