varnishlog not behaving as expected (by me)

[Alex Hooper]

Hi,

It's OK: I'm used to not receiving responses from mailing lists. I have
an unfortunate way of communicating in such forums, I think.

Anyway, having come back to this after a slight hiatus I have noted that
the inclusion of the '-c' flag makes it work as expected.

If I instead include the '-b' flag, it also seems to work as expected
(ie, it doesn't spew output, returns data on backend requests where
tag/regex matched). If I include both -b and -c, it continues to work --
but if I include neither, I get the type of spurious* output I noted
originally, no matter what the combination of tag and regex.

My reading of the man page is that

  varnishlog -o <tag> <regex>

is semantically equivalent to

  varnishlog -b -c -o <tag> <regex>


Either I or the code or the man page would appear to be wrong.

Cheers,

Alex.
