* Add manual pages
Generate manual pages from the README and extend README with Name and
Description sections.
The generation requires 'ronn' which may not be available. Just check in
all generated manual pages.
- added dnstapEncoder object which incapsulates marshalling of dnstap
messages to protobuf and writing data to connection
- dnstapEncoder writes data directly to connection object. It doesn't
use the framestream's "write" method, because it writes data to
intermediate buffer (bufio.Writer) which leads to unnecessary
data copying and drops the performance
- dnstapEncoder reuses a preallocated buffer for marshalling dnstap
messages. Many messages are added to the same buffer. They are
separated with a "frame length" 4-byte values, so the buffer content
is writen to connection object in the format compatible with
framestream library
- added test which guarantees that dnstapEncoder output is the same
as framestream Encoder output
- the performance increase is about 50% in (dio *dnstapIO) serve() method
of dnstap plugin. The overall coredns performance increase is about 10%
in the following configuration:
.:1053 {
erratic {
drop 0
truncate 0
delay 0
}
dnstap tcp://127.0.0.1:6000 full
errors stdout
}
tested with dnsperf tool
Some cleanup in proxy and dnstap:
* just use time pkg directly and side step the indirection for Epoch
* Use Set in SetQueryEpoch to be more Go like. (Looked like a reader)
* Don't maintain two sets of time, we already track start, so use that.
* Use time.Time and convert when needed
* dedent the toDnstap function and put in a separate file
* doc update
Go through all README and fix mistakes, extend example and let more
corefile snippets be test for validity.
* Cant use spefic addr in test
* Add custom data into dnstap context
* Fix error and fix UT compile errors
* Add UTs
* Change as per review comments. Use boolean to indicate which Dnstap message to send out
* Merge with master and fix lint warning
* Remove newline
* Fix review comments
* don't spam Travis + valid dnstap payload
* log instead of fmt
* Revert "log instead of fmt"
This reverts commit 88f09c3939.
* log the right way
* log the final way
* minor enhancements
* Rename middleware to plugin
first pass; mostly used 'sed', few spots where I manually changed
text.
This still builds a coredns binary.
* fmt error
* Rename AddMiddleware to AddPlugin
* Readd AddMiddleware to remain backwards compat
