- changes in ruleutils_11.c is reflected
- vacuum statement api change is handled. We now allow
multi-table vacuum commands.
- some other function header changes are reflected
- api conflicts between PG11 and earlier versions
are handled by adding shims in version_compat.h
- various regression tests are fixed due output and
functionality in PG1
- no change is made to support new features in PG11
they need to be handled by new commit
In DistributedTablesSize() we didn't close the relations that had
replication factor > 2. This caused relcache reference leaks, and
warning messages like following in logs:
WARNING: relcache reference leak: relation "researchers" not closed
If we don't propagate the errors we are catching in PG_CATCH(), database's
internal state might not be clean. So we do PG_TRY() inside a subtransaction
so we can rollback to it after catching errors.
This patch adds --with-reports-host configure option, which sets the
REPORTS_BASE_URL constant. The default is reports.citusdata.com.
It also enables stats collection in tests.
Curl writes the received response to stdout if we don't specify a response
callback or an output file. This can pollute the PostgreSQL log. In this change
we add a callback function so the response messages aren't added to the log file.
Sends a request to /v1/releases/latest?flavor=$CITUS_EDITION once a day,
which returns a response similar to {"version": "7.1.0", "major": 7,
"minor": 1, "patch": 0}. Then compares it with current Citus version,
and if the latest release is newer, logs a LOG message.
This includes:
(1) Wrap everything inside a StartTransactionCommand()/CommitTransactionCommand().
This is so we can access the database. This also switches to a new memory context
and releases it, so we don't have to do our own memory management.
(2) LockCitusExtension() so the extension cannot be dropped or created concurrently.
(3) Check CitusHasBeenLoaded() && CheckCitusVersion() before doing any work.
(4) Do not PG_TRY() inside a loop.
This change introduces the `pg_dist_node_metadata` which has a single jsonb value. When creating
the extension, a random server id is generated and stored in there. Everything in the metadata table
is added as a nested objected to the json payload that is sent to the reports server.
The following scenario can cause an Assert() crash if we don't do this:
- Install Citus v7.0-15
- Restart server & run a query to start maintenanced.
- Install Citus v7.1
- Restart server & run a query. This will tell user to upgrade.
- Type "UPDATE EXTENSION c" & press tab. maintenanced will start and crash
with Assert(CitusHasBeenLoaded() && CheckCitusVersion(WARNING));
This change checks Citus version before calling metadata functions so the
crash doesn't happen.
Eclipse apparently doesn't scan build output looking for -D flags, so
having the value actually appear in a header is nicer for those of us
using IDEs.
Previously <curl/curl.h> was included even if compiled --without-libcurl.
This can fail when libcurl headers are not there. This commit guards this
include by checks for HAVE_LIBCURL.
Adds ```citus.enable_statistics_collection``` GUC variable, which ```true``` by default, unless built without libcurl. If statistics collection is enabled, sends basic usage data to Citus servers every 24 hours.
The data that is collected consists of:
- Citus version
- OS name & release
- Hardware Id
- Number of tables, rounded to next power of 2
- Size of data, rounded to next power of 2
- Number of workers
