The previous parseFill would try to parse an expression and only unscan
one token when it failed. This caused it to not put back the correct
number of tokens with some expression.
Now it has been modified to check for the fill ident ahead of time and
then use ParseExpr() to parse the call. If the expression fails to parse
into a call, it will send an error instead of trying to continue with an
invalid parser state.
Fixes#6543.
Normally, compactions do not conflict on the files they are compacting.
If the full cold threshold is set very low, it can cause conflicts where
two compactions compact the same files. The full compaction was the
only place this could happen as it's planning is greedy.
To make this safer for concurrent execution, the compaction tracks which
files are current being compacted and prevents any new compactions from
starting if the file set overlaps.
Fixes#6595
If a query was running against a file being compacted, we close the file
and the query would end wherever it had read up to. This could result
in queries that randomly lost data, but running them again showed the
full results.
We now use a reference counting approach and move the in-use files out
of the way in the filestore and allow the queries to complete against
the old tsm files. The new files are installed and new queries will
use them.
Fixes#5501
There was a race where the same series would get added to the in-memory
index for a measurement more than once. This would result in the same
series being returned more than once during queries causing duplicate
results. The issue was that we check for the series under the read
lock, but did not check again under the write lock where there was
a small window where the series could be added by another goroutine.
We now check for the series under the write lock.

* Removes sysvinit-tools as an RPM package dependency.
* Update init script to not rely on sysvinit utils for backwards
compatibility.
* Minor overall improvements to init script (improved error messages,
comments, check for root privileges).
* Adds SLES support to post-installation script.
According to the HTTP standard, a lack of authentication credentials or
incorrect authentication credentials should send back a 401
(Unauthorized) with a `WWW-Authenticate` header with a challenge that
can be used to authenticate. This is because a 401 status should be sent
when an authentication attempt can be retried by the browser.
The 403 (Forbidden) status code should be sent when authentication
succeeded, but the user does not have the necessary authorization.
Previously, the server would always send a 401 status code.
Updating the help formatting for all of the commands for consistency.
Removed tabs from the output in favor of using spaces so it is more
clear how the output is intended to look.
Truncate the time interval output of the monitor service to be on even
time intervals rather than on every minute based on the start time. This
normalizes the output from the monitor service.
Previously, it encoded the text representation of the regex literal
which included the surrounding slashes used in the query language. The
binary encoding should only include the exact string used to create the
regular expression.
If there were blocks in later TSM files that were for overwritten
points or writes into the past, they could be returned more than
once or out of order causing the cursor values to be unsorted.
One effect of this is that graphs in graphana would render with
the line going all over the place in spots.
This might also cause duplicate data to be returned.
Fixes#6738
Previously, a non-admin could not call "use" in the influx cli since the
`SHOW DATABASES` command requires admin permissions to run. The correct
solution to this is likely to allow non-admins to call `SHOW DATABASES`,
but only see the databases they should be capable of seeing.
Since we don't have this kind of fine-grained authorization yet and
plans for it are still in the works, we do need someway to not
arbitrarily cripple non-admins attempting to use the cli program. This
is a temporary solution that will ignore any authorization errors from
`SHOW DATABASES` if authorization has been set. A warning message will
be printed and the database will be switched. This should be enough to
ensure that there is some warning that you may not have switched to a
valid database while not crippling non-admin users.
A temporary solution for #6397.
Normalize the output for the various help options so they all follow the
same format and display all relevant options.
Removing some of the unused config options from the configuration file
and updating the help documentation. Removing some remaining references
to clustering within the open source version.
Removes the old implementation of `dumptsm`. It was for an older version
of the tsm1 files that is no longer used and now just panics when used
on a tsm1 file. dumptsmdev has been renamed to `dumptsm`, but the old
`dumptsmdev` command still works for compatibility.
Updated `influx_inspect` to use the `FieldDimensions` method instead
(more reliable anyway). The `influx_tsm` program used its own vendored
copy of `FieldCodec` so it is not affected by this change. `FieldCodec`
was only used for the `b1` and `bz1` engines which were removed in 0.12,
but the code that created the field codec was never removed. This
limited the maximum number of fields to 255 even though that restriction
was removed with the `tsm1` engine.
Fixes#6869.
