The vet checks for some files did not pass for go 1.7. As part of a
preliminary start to making go 1.7 work with this software, go vet
should pass.
Also updated the gogo/protobuf dependency which fixed the code generator
to work with go 1.7 too. Ran `go generate` on the entire repository to
ensure every file was up to date.
When we refactored expvar, the cmdline and memstats sections were not
readded to the output. This adds it back if they can be found inside of
`expvar`.
It also stops trying to sort the output of the statistics so they get
returned faster. JSON doesn't need them to be sorted and it causes
enough latency problems that sorting them hurts performance.
Instead of having the parser set the defaults, the command will set the
defaults so that the constants for that are actually used. This way we
can also identify which things the user provided and which ones we are
filling with default values.
This allows the meta client to be able to make smarter decisions when
determining if the user requested a conflict or if the requested
capabilities match with what is currently available. If you just say
`CREATE DATABASE WITH NAME myrp`, the user doesn't really care what the
duration of the retention policy is and just wants to use the default.
Now, we can use that information to determine if an existing retention
policy would conflict with what the user requested rather than returning
an error if a default value ever gets changed since the meta client
command can communicate intent more easily.
Previously, we implicitly added a newline and had to add one to the
number of bytes transmitted because we added that byte. That was removed
at some point and the metric was not updated to record the correct
value.
The query killing functionality depends on the ResponseWriter exposing a
CloseNotify method. Since we wrap the http.ResponseWriter, the new
struct does not have that method and the HTTP handler would skip past
calling that method.
Instead of duplicating `Flush()` and `CloseNotify()` for every response
formatter, we will unify all of that under a single struct and create
formatters instead.
Also, fixes a bug where the header information from a query would not be
returned until some other data was returned with it because of
buffering and another bug in the gzipResponseWriter that wouldn't flush
the actual underlying ResponseWriter.
The query can be uploaded from a file using `multipart/form-data` and
setting the file name to `q`. An example of using curl to execute an
async query would be:
curl -F "q=@database.iql" -F "async=true" http://localhost:8086/query
It will return a 204 No Content as long as the query is accepted
(immediate errors will be returned, but not individual errors with
specific queries). The only way to kill the query is by using the task
manager.
CSV doesn't offer a way to separate different sheets from each other and
it doesn't really have a standard format. We separate sheets with a
newline so they can be imported into something like Excel or LibreOffice
more easily.
The number of columns for each sheet is inferred from the first returned
row in each statement since they should all be the same.
Instead of having the parser set the defaults, the command will set the
defaults so that the constants for that are actually used. This way we
can also identify which things the user provided and which ones we are

This commit limits queries to only process one shard at a time.
However, within a shard, multiple series can still be processed in
parallel. Shard iterators are lazily instantiated during query
execution to limit the amount of memory a given query uses.
The `Content-Type` header is meant to say what the content type of the
request is supposed to be and `Accept` is used to ask for a specific
content type. I messed this up and used `Content-Type` instead of
`Accept`. This works with `GET` requests accidentally, but `POST`
requests stop working.
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.
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.
Similar to #1339 .
Fix getClientVersion() on setups where the admin interface resides on some
other path than root path due to some reverse proxy setup.
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.
The tsdb package had a substantial amount of dead code related to the
old query engine still in there. It is no longer used, so it was removed
since it was left unmaintained. There is likely still more code that is
the same, but wasn't found as part of this code cleanup.
influxql has dead code show up because of the code generation so it is
not included in this pruning.
The highest time represented by a nanosecond needs to be used for an
exclusive range, so the maximum time needs to be one less than the
possible maximum number of nanoseconds representable by an int64 so that
we don't lose a point at that one time.
Previously worked in the open source version because the timestamp used
for finding a shard would be truncated by the retention policy so the
lookup time didn't run into this edge case because it didn't rest on the
truncation boundary. Since that point didn't really belong in that shard
group and was placed there by mistake, it's best to fix this bug since
the timestamp used to create the shard group should be capable of
retrieving it.
changes the httpd log lines from this:
[httpd] 2016/06/08 14:06:39 ::1 - - [08/Jun/2016:14:06:39 +0100] POST /write?consistency=any&db=telegraf&precision=s&rp= HTTP/1.1 204 0 - InfluxDBClient d6aa01fc-2d79-11e6-8024-000000000000 2.751391ms
to this:
[httpd] ::1 - - [08/Jun/2016:14:06:39 +0100] "POST /write?consistency=any&db=telegraf&precision=s&rp= HTTP/1.1" 204 0 "-" "InfluxDBClient" d6aa01fc-2d79-11e6-8024-000000000000 2751
So it changes a few things:
1. Remove the logger timestamp at the beginning which isn't very relevant anyways
2. adds quotes around "METHOD URI PROTOCOL", because this is part of the
common log format.
3. adds quotes around "AGENT" and "REFERRER" because this is part of the
"combined" log format.
4. Puts the response time in integer microseconds, because this is
consistent with apache's %D config mod option.
Compared with CLF, our logs now look like this:
[httpd] %{COMMON_LOG_FORMAT} "<agent>" "<referrer>" <request_uuid> <response_time_µs>
For reference, see:
https://en.wikipedia.org/wiki/Common_Log_Formathttp://httpd.apache.org/docs/current/mod/mod_log_config.html
The task manager now acts as its own statement executor so that a custom
statement executor can perform custom actions for KillQueryStatement and
ShowQueriesStatement.
The graphite service will attempt to create the retention policy and use
it. If the retention policy doesn't exist, it will be created with the
default options.
Fixes#5655.
This allows us to add additional options to ExecuteQuery without
creating parameter bloat.
Removing the unused Series structs. Their necessity was removed by a
previous commit, but the structs were not removed yet.
Add another type of interrupt iterator that monitors the interrupt
channel and calls `Close()` on the iterator when the interrupt happens.
It will primarily be used for asynchronously closing the ReaderIterator,
but it will only close the read side of the connection properly. More
work needs to be done to allow closing the write side efficiently.
The default retention policy name is changed to "autogen" instead of
"default" since it ends up being ambiguous when we tell a user to check
the default retention policy, it is uncertain if we are referring to the
default retention policy (which can be changed) or the retention policy
with the name "default".
Now the automatically generated retention policy name is "autogen".
The default retention policy is now also configurable through the
configuration file so an administrator can customize what they think
should be the default.
Fixes#3733.
Use the latest documentation by default if the server version can't be
found. If it can be found, update the documentation link to that
specific version so it always points at the exact documentation relevant
for the server version.
Fixes#5906.
The HTTPS configuration for the httpd service only had an option to
specify the certificate file and the same file would be used for both
the certificate and private key file (they could be concatenated
together).
This adds an additional option to specify the files differently from
each other while still allowing the previous behavior. If only
`https-certificate` is specified, the httpd service will try to load the
private key from the `https-certificate` file. If a separate
`https-private-key` file is specified, the private key will be loaded
from there instead.
Fixes#1310.
The parser can be passed a map of keys to literal values to be replaced
into the query. Parameters are preceded by a dollar sign (`$`). If a
parameter key is missing, an error is thrown by the parser.
Fixes#2926.
When authenticating a request, check that an admin user exists instead
of checking for len(users) > 0. This prevents getting stuck with no
admin user and being unable to create one.
The http connection limit is for any HTTP operation and is independent
of the other connection limits. It should be set to a higher value than
the query limit. The difference between this and the query limit is it
will close out the connection immediately without any further
processing.
This is the equivalent of the `max_connections` option in PostgreSQL.
Also removes some unused config options from the cluster config.
Fixes#6559.
