Type of source is checked later anyway and using
ls -p1 results in "dir/", which we should cleanup
with "sed 's;/$;;' again, which is ugly.

The interval definition section was down to just before the
maximum backup check. This makes the code more friendly to
automatic interval selection. Auto interval selection needs to
have ddir defined first and it is best if it is done after
delete_incomplete. This change accomplishes that while still
placing it before the maximum backup check which needs to know
the interval.
so all incomplete backups are deleted, not just the ones with
the particular interval that the user specified.
The advantage of this is that those to-be-deleted incomplete
backups will not interfere with calculations required for
automatic interval selection.
Eight lines and two variables are removed which makes the code,
I think, easier to read.
The main motivation for this change, however, is that it makes
ccollect.sh more friendly to (future) auto interval selection.
The removed lines and variables assumed that the interval was
known prior to the start of the source loop. With auto interval
selection, the selected interval can be different for each
source.
If a source is not connectable, ccollect.sh issues a series of error
messages such as:
$ ccollect.sh "int 1" dummy
2009-06-25-21:04:14: ccollect 0.7.1: Beginning backup using interval int 1
[dummy] 2009-06-25-21:04:14: Beginning to backup
[dummy] ssh: connect to host Ha port 20: No route to host
[dummy] rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
[dummy] rsync error: unexplained error (code 255) at io.c(600) [receiver=3.0.5]
[dummy] 2009-06-25-21:04:17: Error: source Ha:/tmp is not readable. Skipping.
2009-06-25-21:04:17: Finished
If you expect the source to be up, you want to see these messages.
However, for a notebook computer or other portable machine, it may be
normal for it to be disconnected. If quiet_if_down is specified for
that source, then the ssh and rsync errors are suppressed and the
"Error:" prefix is removed from the "skipping" message:
$ ccollect.sh "int 1" dummy
2009-06-25-21:03:33: ccollect 0.7.1: Beginning backup using interval int 1
[dummy] 2009-06-25-21:03:34: Beginning to backup
[dummy] 2009-06-25-21:03:37: Source Ha:/tmp is not readable. Skipping.
2009-06-25-21:03:37: Finished
I considered the alternative implementation of adding the logic to
ccollect_analyse_logs.sh to enable it to separate rsync messages
generated the initial connection test from messages generated by
rsync used for an actual backup data transfer. Adding this approach
to ccollect.sh appeared much simpler.
By default, ccollect.sh sorts backup directories based on last change
time (ctime). This adds the option to sort based on modification
time (mtime).
I have updated doc/ccollect.text but it needs some work to simplify
and explain the issue.
