i used this script, a little clunky but it got the job done
```bash
for file in `find . -type f -print | grep '\.go'`; do
sed '1,/^\/\/ limitations under the License.$/d' $file > $file.tmp;
result=`cat $file.tmp`
if [[ result != "" ]]; then
gofmt $file.tmp &> /dev/null;
if [[ $? == 0 ]]; then
mv $file.tmp $file && gofmt -w $file;
else
rm $file.tmp;
fi
else
rm $file.tmp;
fi
done
```
The "just open the holder" subcommand doesn't work the way it used
to, because now that we rely on etcd to open a holder, trying to open
a holder without things set up just coredumps.
Step 1: Fix that.
Step 2: Also add a test that covers it so we don't get bitrotted again.
Step 3: Remove an unrelated stale comment that doesn't deserve its
own commit log, having to do with an option that no longer exists
which is no longer being set right under the comment saying we set it.
Underlying goal: Don't use the http client to send messages back to the
local host. Also, when sending data to other nodes, don't collate it
from an ImportRequest into a completely different format, then immediately
collate that back into an ImportRequest. This does require changing
the logic over in ctl/import to make it create an ImportRequest.
Also, add additional testing to make sure we're actually trying anything
at all with several combinations (such as submitting import requests
which don't match the configuration of index or field), and improve
test coverage for that.
This introduces the ability to tell an http/client InternalClient about
a specific API that it should use for local queries where applicable.
That's not implemented outside of the import stuff, but should probably
be applied eventually to other things that are trying to talk to many
nodes one of which may be the local node. That behavior is contingent
on passing in a Qcx, because it is implicitly tied to an existing
execution context, and it can't assume that it can create a new one,
because that could deadlock.
Attributes are unmaintained and unused.
They have become more of a liability than a benefit.
This change eliminates them from the codebase.
The only user-visible change (assuming that attrs are not used) is that the attrs field will no longer appear in row JSON.
We check mmap limits, and try to set/increase our open file limits,
and we check the mmap limit when we start the server, and try to set
the open file limit every time we open a holder.
It's useless to do these things more than once, though. We migrate
these things to be run through a sync.Once, which runs all of them
the first time a server starts up, and then thereafter just returns
the error code from that first run. This should make test startup
ever so slightly cheaper, saving us potentially several microseconds,
but also reducing the spamminess of the message.
I've taken out the `sudo ulimit` advice since it's wrong, and the
documentation link is updated to point to our (now private!)
customer documentation.
