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
This build is allowed to fail and finish-fast is enabled, so there is
no negative impact on developers, yet we can now stay better abreast of
upcoming PostgreSQL changes.
The latest citus tools version also adds enable-depend to the flags in
our "custom PG" source-based builds which will result in fewer false
failures due to build caching behavior.
Adds support for PostgreSQL 10 by copying in the requisite ruleutils
and updating all API usages to conform with changes in PostgreSQL 10.
Most changes are fairly minor but they are numerous. One particular
obstacle was the change in \d behavior in PostgreSQL 10's psql; I had
to add SQL implementations (views, mostly) to mimic the pre-10 output.
The use of a bare src/ rather than $srcdir caused configure to fail
during VPATH builds. With our additional dependency upon AWK, we need
to call AC_PROG_AWK, otherwise environments may not have $AWK set.
Finally, citus_version.h should be in .gitignore.
With this change, we start to error out if loaded citus binaries does not match
the available major version or installed citus extension version. In this case
we force user to restart the server or run ALTER EXTENSION depending on the
situation
Adds an --enable-coverage configure option which provides the necessary
flags for coverage instrumentation. A new tools branch uses this flag
during all builds. Coverage reports are uploaded to codecov.io, where
they are publicly visible.
That's useful when trying to rely on files only present in source and/or
build directories, not in the normal installation. E.g. the
isolationtester binary, or the valgrind suppression files.
Adds support for PostgreSQL 9.6 by copying in the requisite ruleutils
file and refactoring the out/readfuncs code to flexibly support the
old-style copy/pasted out/readfuncs (prior to 9.6) or use extensible
node APIs (in 9.6 and higher).
Most version-specific code within this change is only needed to set new
fields in the AggRef nodes we build for aggregations. Version-specific
test output files were added in certain cases, though in most they were
not necessary. Each such file begins by e.g. printing the major version
in order to clarify its purpose.
The comment atop citus_nodes.h details how to add support for new nodes
for when that becomes necessary.
If postgres was compiled without flex support - possible when building
from a tarball, because those contain the flex generated files - citus
compilation would fail, because FLEX is defined as missing.
Add detection for flex, overwriting postgres' detection if one was
found.
Fixes: #439
All citusdb references in
- extension, binary names
- file headers
- all configuration name prefixes
- error/warning messages
- some functions names
- regression tests
are changed to be citus.
