ckolivas ae63349e3c We do need to seek to read the MD5 correctly on very small files so support seeking to end and then seek to the md5 start. 2011-03-17 11:53:29 +11:00

Con Kolivas c75a50f723 Being modifying write_1g function to be able to write to a temporary buffer instead of straight to fd_out.

Con Kolivas 13a6fb5b43 Dump the temporary file generated to emulate stdout at the end of each chunk on decompression and then truncate the file instead of writing the whole file before dumping it. 2011-03-07 17:14:07 +11:00
Con Kolivas a7b4708bd2 Use a different failure mode for when perror is unlikely to be set.

 2011-02-21 14:51:20 +11:00
Con Kolivas 57e25da244 Update copyright yeah in updated files. 2011-02-20 23:04:44 +11:00
Con Kolivas 7b073160a3 Can't always open fd_out in runzip for integrity testing, so use fd_hist. 2011-02-20 22:44:10 +11:00
Con Kolivas 9b264959f5 Implement the ability to test the integrity of the file written to disk on decompression. 2011-02-20 22:29:49 +11:00
Con Kolivas 8a27dc5057 Changes to make md5 be used for integrity testing. 
Add the md5 value to the end of each archive.
This can then be used for integrity testing instead of crc32.
Keep crc in new archives to maintain compatibility with version 0.5 files.
Use md5 integrity testing on decompression when available in preference, and disable calculation of crc32.
Display the choice of integrity testing in verbose output and when -i is used.
Display the md5 and crc values when max verbosity, file info, or display hash is enabled.
Store a new flag in the magic header to show that the md5 value is stored at the end of the file.
Update the magic header information document.
