We only have 4 bytes for offsets, but what if a file is
over 4GB? Someone came to us with a file with 265 *million* containers,
in a single fragment, which means that over 3GB of their 4.7GB file
is actually just the container headers alone. But we can't easily make
the offsets larger, or change the file format.
So we don't. We just track how many 4GB hunks of the file we've
been through and bump that every time the 32-bit offset wraps. And this
appears to... just work.
This is fixed for both the roaring iterator and the old unmarshalBinary
logic. The logic to handle this will work on 32-bit hosts in the sense
that it will correctly error out for excessively large file sizes or
container counts, but it doesn't actually handle the large files since
it can't.
When the interval is a proper superset of the range with start equal to
interval start, the range must be considered a superset or it will be
completly ignored (since it neither a subset nor it overlaps)
Without this, a data set with a ludicrously large value in it
could break a BSI field's depth even though the import would then
reject it.
always treat BSI fields as having at least their depth:
If you imported only small values, BSI fields could end up
not bothering to clear higher bits in existing values, which
produced strange behaviors.
This change should have been adding the "GetClientCertificate"
function in server/tlsconfig.go. This is in addition to the
GetCertificate func which is only used by servers. It ended up being
much more involved for a few reasons:
1. We had no way of passing a configured HTTP client into the
translate store stuff.
2. Our cluster tests assumed http, not HTTPS, and didn't have any way
to pass the necessary configuration in.
3. I encountered what turned out to be an unrelated bug in
cmd/server_test.go which is why I moved "close(m.Started)" in
server/server.go. Basically, I was running something on port 10111
which caused the test to fail (because it was trying to bind to that),
but the failure was not immediately caught during server startup
because the m.Started channel got closed which allowed the test code
to fall through to where it called m.Close() which then got a nil
pointer exception because m.Handler had never been set up.
4. Our test code was assuming that it could create clients that
ignored the config, which meant they didn't do TLS. I added an
InternalClient() method to pilosa.Server to expose the configured
client.
