Attention is currently required from: flichtenheld, plaisthos.
Hello flichtenheld,
I'd like you to reexamine a change. Please visit
http://gerrit.openvpn.net/c/openvpn/+/1942?usp=email
to look at the new patch set (#3).
The following approvals got outdated and were removed:
Code-Review-1 by flichtenheld
Change subject: Change most ENABLE_DEBUG ifdefs to ifndef ENABLE_SMALL
......................................................................
Change most ENABLE_DEBUG ifdefs to ifndef ENABLE_SMALL
Most of these are verbose logging or even enable logging at high
verbosity level or just useful tools like --show-gateway.
We had --enabled-debug on by default forever, so these "debug"
logs are on by default. This patch instead moves them to
enable-small.
Since the verbose logging is now always enabled
(apart from --enable-small), --enable-debug now only covers true
debug options like gremlin.
Rename the configure option from --enable-debug to
--enable-developer-debug to ensure existing build
script/maintainer do not enable this option
by default.
