I have prepared 2 files, one with uncompressed 11964 bytes, the other
with 11965 bytes uncompressed. I'll try the verbose test with the
bigger file ...

Just one check: does the problem happen only with large compressed
files, or does it happen also with large uncompressed files?

If it doesn't in the latter case, then it might be a problem of saving
the binary data from the temporary buffer. Maybe something because of
the unicode merge (wild guess, I know).


There might be even more bugs! Yesterday I built my test files on command line with split. In dired i gzip'ed them – und two lines became one! Today I tried to gunzip the two files to test uncompressed transfer – and again two lines became one in dired. At both times only one file was gzip'ed or gunzip'ed.

Uncompresses text (LOG) files up to almost 16 MB are transferred fine. My check was simple: viewing the original file in dired and viewing the copy in dired. Then doing a compare-windows.

I also fetched the files with sftp and invoked diff on the command line, diff between the copied and the sftp'ed file. The differences found were new log entries.


How does v(iewing) a remote gzip'ed file in dired work? This never showed a(n obvious) problem ...

I again could observe that the remote server delivers data at varying rates from less than 10 kB/sec to up to 120 kB/sec. Sftp showed a more stable and higher transfer rate.

I'm off now for some hours!
