BSD-2-Clause
* Sat Nov 18 2023 Dirk Müller <dmueller@suse.com>
- update to 2.3.0:
* Partial support of topic identifiers. Topic identifiers in
metadata response available through the new
`rd_kafka_DescribeTopics` function
* KIP-117 Add support for AdminAPI `DescribeCluster()` and
`DescribeTopics()`
* Return authorized operations in Describe Responses.
* KIP-580: Added Exponential Backoff mechanism for
retriable requests with `retry.backoff.ms` as minimum backoff
and `retry.backoff.max.ms` as the
maximum backoff, with 20% jitter (#4422).
* Fixed ListConsumerGroupOffsets not fetching offsets for all
the topics in a group with Apache Kafka version below 2.4.0.
* Add missing destroy that leads to leaking partition structure
memory when there are partition leader changes and a stale
leader epoch is received (#4429).
* Fix a segmentation fault when closing a consumer using the
cooperative-sticky assignor before the first assignment
* Fix for insufficient buffer allocation when allocating rack
information (@wolfchimneyrock, #4449).
* Fix for infinite loop of OffsetForLeaderEpoch requests on
quick leader changes. (#4433).
* Fix for stored offsets not being committed if they lacked the
leader epoch (#4442).
* Upgrade OpenSSL to v3.0.11 (while building from source) with
various security fixes, check the release notes
* Fix to ensure permanent errors during offset validation
continue being retried and don't cause an offset reset (#4447).
* Fix to ensure max.poll.interval.ms is reset when
rd_kafka_poll is called with consume_cb (#4431).
* Fix for idempotent producer fatal errors, triggered after a
possibly persisted message state (#4438).
* Fix `rd_kafka_query_watermark_offsets` continuing beyond
timeout expiry (#4460).
* Fix `rd_kafka_query_watermark_offsets` not refreshing the
partition leader after a leader change and subsequent
`NOT_LEADER_OR_FOLLOWER` error (#4225).
* Sun May 07 2023 Dirk Müller <dmueller@suse.com>
- update to 2.1.1:
* Avoid duplicate messages when a fetch response is received
* in the middle of an offset validation request
* Fix segmentation fault when subscribing to a non-existent
topic and calling `rd_kafka_message_leader_epoch()` on the polled
`rkmessage`
* Fix a segmentation fault when fetching from follower and the
partition lease expires while waiting for the result of a list offsets
operation
* Fix documentation for the admin request timeout, incorrectly
stating -1 for infinite
* timeout. That timeout can't be infinite.
* Fix CMake pkg-config cURL require and use
* pkg-config `Requires.private` field
* Fixes certain cases where polling would not keep the consumer
* in the group or make it rejoin it
* Fix to the C++ set_leader_epoch method of TopicPartitionImpl,
* that wasn't storing the passed value
* Duplicate messages can be emitted when a fetch response is
received in the middle of an offset validation request. Solved by
avoiding a restart from last application offset when offset validation
succeeds.
* When fetching from follower, if the partition lease expires
after 5 minutes, and a list offsets operation was requested
to retrieve the earliest or latest offset, it resulted in
segmentation fault. This was fixed by allowing threads different
from the main one to call the `rd_kafka_toppar_set_fetch_state`
function, given they hold the lock on the `rktp`.
* In v2.1.0, a bug was fixed which caused polling any queue to
reset the `max.poll.interval.ms`.
Only certain functions were made to reset the timer,
but it is possible for the user to obtain the queue with
messages from the broker, skipping these functions. This was fixed by
encoding information in a queue itself, that, whether polling,
resets the timer.
* Thu Apr 27 2023 Dirk Müller <dmueller@suse.com>
- update to 2.1.0:
* Allow fetchers to detect and handle log truncation (#4122).
* Fix a reference count issue blocking the consumer from
closing (#4187).
* Fix a protocol issue with ListGroups API, where an extra
* field was appended for API Versions greater than or equal to
3 (#4207).
* Fix an issue with `max.poll.interval.ms`, where polling any
queue would cause the timeout to be reset (#4176).
* Fix seek partition timeout, was one thousand times lower than
the passed value (#4230).
* Fix multiple inconsistent behaviour in batch APIs during
* *pause** or **resume** operations (#4208).
* Update lz4.c from upstream. Fixes CVE-2021-3520
* Upgrade OpenSSL to v3.0.8 with various security fixes
* Added `rd_kafka_topic_partition_get_leader_epoch()` (and
`set..()`).
* A reference count issue was blocking the consumer from
closing.
* Fixed known issues related to Batch Consume APIs mentioned in
v2.0.0 release notes.
* Fixed `rd_kafka_consume_batch()` and `rd_kafka_consume_batch_queue()`
intermittently updating `app_offset` and `store_offset`
incorrectly when **pause** or **resume** was being used for a partition.
* Fixed `rd_kafka_consume_batch()` and `rd_kafka_consume_batch_queue()`
intermittently skipping offsets when **pause** or **resume**
was being used for a partition.
* Sun Jan 29 2023 Dirk Müller <dmueller@suse.com>
- update to 2.0.2:
* OffsetFetch Protocol Update (#3995).
* Add Consumer Group operations to Admin API (started by @lesterfan, #3995).
* Allow listing consumer groups per state (#3995).
* Partially implemented: support for AlterConsumerGroupOffsets
* OpenSSL 3.0.x support - the maximum bundled OpenSSL version is now 3.0.7 (previously 1.1.1q).
* Fixes to the transactional and idempotent producer.
* The introduction of OpenSSL 3.0.x in the self-contained librdkafka
bundles changes the default set of available ciphers, in particular all obsolete
or insecure ciphers and algorithms as listed in the OpenSSL legacy
manual page are now disabled by default.
Should you need to use any of these old ciphers you'll need to
explicitly enable the `legacy` provider by configuring
`ssl.providers=default,legacy` on the librdkafka client.
OpenSSL 3.0.x deprecates the use of engines, which is being replaced by
providers. As such librdkafka will emit a deprecation warning if
`ssl.engine.location` is configured. OpenSSL providers may be
configured with the new `ssl.providers` configuration property.
The default value for `ssl.endpoint.identification.algorithm` has been
changed from `none` (no hostname verification) to `https`, which enables
broker hostname verification (to counter man-in-the-middle
impersonation attacks) by default. To restore the previous behaviour, set
`ssl.endpoint.identification.algorithm` to `none`.
* The Consumer Batch APIs `rd_kafka_consume_batch()` and
`rd_kafka_consume_batch_queue()` are not thread safe if
`rkmessages_size` is greater than 1 and any of the **seek**,
* *pause**, **resume** or **rebalancing** operation is performed in
parallel with any of the above APIs. Some of the messages might be
lost, or erroneously returned to the application, in the above scenario.
* It is strongly recommended to use the Consumer Batch APIs and the
mentioned operations in sequential order in order to get consistent result.
* For **rebalancing** operation to work in sequencial manner, please set
`rebalance_cb` configuration property (refer
[examples/rdkafka_complex_consumer_example.c]
* (examples/rdkafka_complex_consumer_example.c) for the help with the
usage) for the consumer.
* Added `rd_kafka_sasl_set_credentials()` API to update SASL credentials.
* Setting `allow.auto.create.topics` will no longer give a warning if used
by a producer, since that is an expected use case. Improvement in
documentation for this property.
* Added a `resolve_cb` configuration setting that permits using custom
DNS resolution logic.
* Added `rd_kafka_mock_broker_error_stack_cnt()`.
* The librdkafka.redist NuGet package has been updated to have fewer external
dependencies for its bundled librdkafka builds, as everything but cyrus-sasl
is now built-in. There are bundled builds with and without linking to
cyrus-sasl for maximum compatibility.
* Admin API DescribeGroups() now provides the group instance id
for static members KIP-345 (#3995).
* Fixed memory leak when loading SSL certificates (@Mekk, #3930)
* Load all CA certificates from `ssl.ca.pem`, not just the first one.
* Each HTTP request made when using OAUTHBEARER OIDC would leak a small
amount of memory.
* When a PID epoch bump is requested and the producer is waiting
to reconnect to the transaction coordinator, a failure in a find coordinator
request could cause an assert to fail. This is fixed by retrying when the
coordinator is known (#4020).
* Transactional APIs (except `send_offsets_for_transaction()`) that
timeout due to low timeout_ms may now be resumed by calling the same API
again, as the operation continues in the background.
* For fatal idempotent producer errors that may be recovered by bumping the
epoch the current transaction must first be aborted prior to the epoch bump.
This is now handled correctly, which fixes issues seen with fenced
transactional producers on fatal idempotency errors.
* Timeouts for EndTxn requests (transaction commits and aborts) are now
automatically retried and the error raised to the application is also
a retriable error.
* TxnOffsetCommitRequests were retried immediately upon temporary errors in
`send_offsets_to_transactions()`, causing excessive network requests.
These retries are now delayed 500ms.
* If `init_transactions()` is called with an infinite timeout (-1),
the timeout will be limited to 2 * `transaction.timeout.ms`.
The application may retry and resume the call if a retriable error is
returned.
* Back-off and retry JoinGroup request if coordinator load is in progress.
* Fix `rd_kafka_consume_batch()` and `rd_kafka_consume_batch_queue()` skipping
other partitions' offsets intermittently when **seek**, **pause**, **resume**
or **rebalancing** is used for a partition.
* Fix `rd_kafka_consume_batch()` and `rd_kafka_consume_batch_queue()`
intermittently returing incorrect partitions' messages if **rebalancing**
happens during these operations.
* Mon Sep 12 2022 Dirk Müller <dmueller@suse.com>
- update to 1.9.2:
* Added KIP-768 OUATHBEARER OIDC support (by @jliunyu, #3560)
* Added KIP-140 Admin API ACL support (by @emasab, #2676)
* Consumer:
`rd_kafka_offsets_store()` (et.al) will now return an error for any
partition that is not currently assigned (through `rd_kafka_*assign()`).
This prevents a race condition where an application would store offsets
after the assigned partitions had been revoked (which resets the stored
offset), that could cause these old stored offsets to be committed later
when the same partitions were assigned to this consumer again - effectively
overwriting any committed offsets by any consumers that were assigned the
same partitions previously. This would typically result in the offsets
rewinding and messages to be reprocessed.
As an extra effort to avoid this situation the stored offset is now
also reset when partitions are assigned (through `rd_kafka_*assign()`).
Applications that explicitly call `..offset*_store()` will now need
to handle the case where `RD_KAFKA_RESP_ERR__STATE` is returned
in the per-partition `.err` field - meaning the partition is no longer
assigned to this consumer and the offset could not be stored for commit.
* Improved producer queue scheduling. Fixes the performance regression
introduced in v1.7.0 for some produce patterns. (#3538, #2912)
* Windows: Added native Win32 IO/Queue scheduling. This removes the
internal TCP loopback connections that were previously used for timely
queue wakeups.
* Added `socket.connection.setup.timeout.ms` (default 30s).
The maximum time allowed for broker connection setups (TCP connection as
well as SSL and SASL handshakes) is now limited to this value.
This fixes the issue with stalled broker connections in the case of network
or load balancer problems.
The Java clients has an exponential backoff to this timeout which is
limited by `socket.connection.setup.timeout.max.ms` - this was not
implemented in librdkafka due to differences in connection handling and
`ERR__ALL_BROKERS_DOWN` error reporting. Having a lower initial connection
setup timeout and then increase the timeout for the next attempt would
yield possibly false-positive `ERR__ALL_BROKERS_DOWN` too early.
* SASL OAUTHBEARER refresh callbacks can now be scheduled for execution
on librdkafka's background thread. This solves the problem where an
application has a custom SASL OAUTHBEARER refresh callback and thus needs to
call `rd_kafka_poll()` (et.al.) at least once to trigger the
refresh callback before being able to connect to brokers.
With the new `rd_kafka_conf_enable_sasl_queue()` configuration API and
`rd_kafka_sasl_background_callbacks_enable()` the refresh callbacks
can now be triggered automatically on the librdkafka background thread.
* `rd_kafka_queue_get_background()` now creates the background thread
if not already created.
* Added `rd_kafka_consumer_close_queue()` and `rd_kafka_consumer_closed()`.
This allow applications and language bindings to implement asynchronous
consumer close.
* Bundled zlib upgraded to version 1.2.12.
* Bundled OpenSSL upgraded to 1.1.1n.
* Added `test.mock.broker.rtt` to simulate RTT/latency for mock brokers.
- enable libcurl integration
- enable RapidJSON integration
* Tue Jan 04 2022 Dirk Müller <dmueller@suse.com>
- update to 1.8.2:
* Added ssl.ca.pem to add CA certificate by PEM string
* Upon quick repeated leader changes the transactional producer could receive
an OUT_OF_ORDER_SEQUENCE error from the broker
* The transactional producer could stall during a transaction if the transaction
coordinator changed
* Sat Oct 16 2021 Dirk Müller <dmueller@suse.com>
- update to 1.8.0:
* Upgrade bundled zlib version from 1.2.8 to 1.2.11 in the `librdkafka.redist`
NuGet package. The updated zlib version fixes CVEs:
CVE-2016-9840, CVE-2016-9841, CVE-2016-9842, CVE-2016-9843
See https://github.com/edenhill/librdkafka/issues/2934 for more information.
* librdkafka now uses [vcpkg](https://vcpkg.io/) for up-to-date Windows
dependencies in the `librdkafka.redist` NuGet package:
OpenSSL 1.1.1l, zlib 1.2.11, zstd 1.5.0.
* The upstream dependency (OpenSSL, zstd, zlib) source archive checksums are
now verified when building with `./configure --install-deps`.
These builds are used by the librdkafka builds bundled with
confluent-kafka-go, confluent-kafka-python and confluent-kafka-dotnet.
* Producer `flush()` now overrides the `linger.ms` setting for the duration
of the `flush()` call, effectively triggering immediate transmission of
queued messages. (#3489)
* Lots of bugfixes, see included CHANGELOG.md for details
- build against system libraries rather than bundled ones
- enable all features
* Sun Jun 06 2021 Dirk Müller <dmueller@suse.com>
- update to 1.7.0:
* [KIP-360](https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=89068820) - Improve reliability of transactional producer.
Requires Apache Kafka 2.5 or later.
* OpenSSL Engine support (`ssl.engine.location`) by @adinigam and @ajbarb.
* Added `connections.max.idle.ms` to automatically close idle broker
connections.
This feature is disabled by default unless `bootstrap.servers` contains
the string `azure` in which case the default is set to <4 minutes to improve
connection reliability and circumvent limitations with the Azure load
balancers (see #3109 for more information).
* Bumped to OpenSSL 1.1.1k in binary librdkafka artifacts.
* The binary librdkafka artifacts for Alpine are now using Alpine 3.12.
OpenSSL 1.1.1k.
* Improved static librdkafka Windows builds using MinGW (@neptoess, #3130).
* The C++ `oauthbearer_token_refresh_cb()` was missing a `Handle *`
argument that has now been added. This is a breaking change but the original
function signature is considered a bug.
This change only affects C++ OAuth developers.
* [KIP-735](https://cwiki.apache.org/confluence/display/KAFKA/KIP-735%3A+Increase+default+consumer+session+timeout) The consumer `session.timeout.ms`
default was changed from 10 to 45 seconds to make consumer groups more
robust and less sensitive to temporary network and cluster issues.
* Statistics: `consumer_lag` is now using the `committed_offset`,
while the new `consumer_lag_stored` is using `stored_offset`
(offset to be committed).
This is more correct than the previous `consumer_lag` which was using
either `committed_offset` or `app_offset` (last message passed
to application).
* Bugfixes
* Mon Apr 26 2021 Dirk Müller <dmueller@suse.com>
- update to 1.6.1:
* Fatal idempotent producer errors are now also fatal to the transactional
producer. This is a necessary step to maintain data integrity prior to
librdkafka supporting KIP-360. Applications should check any transactional
API errors for the is_fatal flag and decommission the transactional producer
if the flag is set.
* The consumer error raised by `auto.offset.reset=error` now has error-code
set to `ERR__AUTO_OFFSET_RESET` to allow an application to differentiate
between auto offset resets and other consumer errors.
* Admin API and transactional `send_offsets_to_transaction()` coordinator
requests, such as TxnOffsetCommitRequest, could in rare cases be sent
multiple times which could cause a crash.
* `ssl.ca.location=probe` is now enabled by default on Mac OSX since the
librdkafka-bundled OpenSSL might not have the same default CA search paths
as the system or brew installed OpenSSL. Probing scans all known locations.
* Fatal idempotent producer errors are now also fatal to the transactional
producer.
* The transactional producer could crash if the transaction failed while
`send_offsets_to_transaction()` was called.
* Group coordinator requests for transactional
`send_offsets_to_transaction()` calls would leak memory if the
underlying request was attempted to be sent after the transaction had
failed.
* When gradually producing to multiple partitions (resulting in multiple
underlying AddPartitionsToTxnRequests) sub-sequent partitions could get
stuck in pending state under certain conditions. These pending partitions
would not send queued messages to the broker and eventually trigger
message timeouts, failing the current transaction. This is now fixed.
* Committing an empty transaction (no messages were produced and no
offsets were sent) would previously raise a fatal error due to invalid state
on the transaction coordinator. We now allow empty/no-op transactions to
be committed.
* The consumer will now retry indefinitely (or until the assignment is changed)
to retrieve committed offsets. This fixes the issue where only two retries
were attempted when outstanding transactions were blocking OffsetFetch
requests with `ERR_UNSTABLE_OFFSET_COMMIT`. #3265
* [KIP-429 Incremental rebalancing](https://cwiki.apache.org/confluence/display/KAFKA/KIP-429%3A+Kafka+Consumer+Incremental+Rebalance+Protocol) with sticky
consumer group partition assignor (KIP-54) (by @mhowlett).
* [KIP-480 Sticky producer partitioning](https://cwiki.apache.org/confluence/display/KAFKA/KIP-480%3A+Sticky+Partitioner) (`sticky.partitioning.linger.ms`) -
achieves higher throughput and lower latency through sticky selection
of random partition (by @abbycriswell).
* AdminAPI: Add support for `DeleteRecords()`, `DeleteGroups()` and
`DeleteConsumerGroupOffsets()` (by @gridaphobe)
* [KIP-447 Producer scalability for exactly once semantics](https://cwiki.apache.org/confluence/display/KAFKA/KIP-447%3A+Producer+scalability+for+exactly+once+semantics) -
allows a single transactional producer to be used for multiple input
partitions. Requires Apache Kafka 2.5 or later.
* Transactional producer fixes and improvements, see **Transactional Producer fixes** below.
* The [librdkafka.redist](https://www.nuget.org/packages/librdkafka.redist/)
NuGet package now supports Linux ARM64/Aarch64.
* Sticky producer partitioning (`sticky.partitioning.linger.ms`) is
enabled by default (10 milliseconds) which affects the distribution of
randomly partitioned messages, where previously these messages would be
evenly distributed over the available partitions they are now partitioned
to a single partition for the duration of the sticky time
(10 milliseconds by default) before a new random sticky partition
is selected.
* The new KIP-447 transactional producer scalability guarantees are only
supported on Apache Kafka 2.5 or later, on earlier releases you will
need to use one producer per input partition for EOS. This limitation
is not enforced by the producer or broker.
* Error handling for the transactional producer has been improved, see
the **Transactional Producer fixes** below for more information.
* KIP-107, KIP-204: AdminAPI: Added `DeleteRecords()` (by @gridaphobe).
* KIP-229: AdminAPI: Added `DeleteGroups()` (by @gridaphobe).
* KIP-496: AdminAPI: Added `DeleteConsumerGroupOffsets()`.
* KIP-464: AdminAPI: Added support for broker-side default partition count
and replication factor for `CreateTopics()`.
* Windows: Added `ssl.ca.certificate.stores` to specify a list of
Windows Certificate Stores to read CA certificates from, e.g.,
`CA,Root`. `Root` remains the default store.
* Use reentrant `rand_r()` on supporting platforms which decreases lock
contention (@azat).
* Added `assignor` debug context for troubleshooting consumer partition
assignments.
* Updated to OpenSSL v1.1.1i when building dependencies.
* Update bundled lz4 (used when `./configure --disable-lz4-ext`) to v1.9.3
which has vast performance improvements.
* Added `rd_kafka_conf_get_default_topic_conf()` to retrieve the
default topic configuration object from a global configuration object.
* Added `conf` debugging context to `debug` - shows set configuration
properties on client and topic instantiation. Sensitive properties
are redacted.
* Added `rd_kafka_queue_yield()` to cancel a blocking queue call.
* Will now log a warning when multiple ClusterIds are seen, which is an
indication that the client might be erroneously configured to connect to
multiple clusters which is not supported.
* Added `rd_kafka_seek_partitions()` to seek multiple partitions to
per-partition specific offsets.
* Fix a use-after-free crash when certain coordinator requests were retried.
* The C++ `oauthbearer_set_token()` function would call `free()` on
a `new`-created pointer, possibly leading to crashes or heap corruption (#3194)
* The consumer assignment and consumer group implementations have been
decoupled, simplified and made more strict and robust. This will sort out
a number of edge cases for the consumer where the behaviour was previously
undefined.
* Partition fetch state was not set to STOPPED if OffsetCommit failed.
* The session timeout is now enforced locally also when the coordinator
connection is down, which was not previously the case.
* Transaction commit or abort failures on the broker, such as when the
producer was fenced by a newer instance, were not propagated to the
application resulting in failed commits seeming successful.
This was a critical race condition for applications that had a delay after
producing messages (or sendings offsets) before committing or
aborting the transaction. This issue has now been fixed and test coverage
improved.
* The transactional producer API would return `RD_KAFKA_RESP_ERR__STATE`
when API calls were attempted after the transaction had failed, we now
try to return the error that caused the transaction to fail in the first
place, such as `RD_KAFKA_RESP_ERR__FENCED` when the producer has
been fenced, or `RD_KAFKA_RESP_ERR__TIMED_OUT` when the transaction
has timed out.
* Transactional producer retry count for transactional control protocol
requests has been increased from 3 to infinite, retriable errors
are now automatically retried by the producer until success or the
transaction timeout is exceeded. This fixes the case where
`rd_kafka_send_offsets_to_transaction()` would fail the current
transaction into an abortable state when `CONCURRENT_TRANSACTIONS` was
returned by the broker (which is a transient error) and the 3 retries
were exhausted.
* Calling `rd_kafka_topic_new()` with a topic config object with
`message.timeout.ms` set could sometimes adjust the global `linger.ms`
property (if not explicitly configured) which was not desired, this is now
fixed and the auto adjustment is only done based on the
`default_topic_conf` at producer creation.
* `rd_kafka_flush()` could previously return `RD_KAFKA_RESP_ERR__TIMED_OUT`
just as the timeout was reached if the messages had been flushed but
there were now no more messages. This has been fixed.
* Tue Dec 22 2020 Dirk Müller <dmueller@suse.com>
- update to 1.5.3:
* Fix a use-after-free crash when certain coordinator requests were retried.
* Consumer would not filter out messages for aborted transactions
if the messages were compressed (#3020).
* Consumer destroy without prior `close()` could hang in certain
cgrp states (@gridaphobe, #3127).
* Fix possible null dereference in `Message::errstr()` (#3140).
* The `roundrobin` partition assignment strategy could get stuck in an
endless loop or generate uneven assignments in case the group members
had asymmetric subscriptions (e.g., c1 subscribes to t1,t2 while c2
subscribes to t2,t3). (#3159)
* Mon Oct 26 2020 Dirk Mueller <dmueller@suse.com>
- update to 1.5.2:
* Security fixes: There was an incorrect call to zlib's inflateGetHeader()
with unitialized memory pointers that could lead to the GZIP header of a
fetched message batch to be copied to arbitrary memory.
* The default value for the producer configuration property retries has
been increased from 2 to infinity
* The default value for the producer configuration property
request.timeout.ms has been increased from 5 to 30 seconds
* lots of bugfixes, see https://raw.githubusercontent.com/edenhill/librdkafka/v1.5.2/CHANGELOG.md
* Fri Aug 21 2020 Chris Coutinho <chrisbcoutinho@gmail.com>
- Update library v1.3.0 -> 1.5.0
* Improved broker connection error reporting with more useful information and
hints on the cause of the problem.
* Consumer: Propagate errors when subscribing to unavailable topics (#1540)
* Producer: Add `batch.size` producer configuration property (#638)
* Add `topic.metadata.propagation.max.ms` to allow newly manually created
topics to be propagated throughout the cluster before reporting them
as non-existent. This fixes race issues where CreateTopics() is
quickly followed by produce().
* Prefer least idle connection for periodic metadata refreshes, et.al.,
to allow truly idle connections to time out and to avoid load-balancer-killed
idle connection errors (#2845)
* Added `rd_kafka_event_debug_contexts()` to get the debug contexts for
a debug log line (by @wolfchimneyrock).
* Added Test scenarios which define the cluster configuration.
* Added MinGW-w64 builds (@ed-alertedh, #2553)
* `./configure --enable-XYZ` now requires the XYZ check to pass,
and `--disable-XYZ` disables the feature altogether (@benesch)
* Added `rd_kafka_produceva()` which takes an array of produce arguments
for situations where the existing `rd_kafka_producev()` va-arg approach
can't be used.
* Added `rd_kafka_message_broker_id()` to see the broker that a message
was produced or fetched from, or an error was associated with.
* Added RTT/delay simulation to mock brokers.
* Subscribing to non-existent and unauthorized topics will now propagate
errors `RD_KAFKA_RESP_ERR_UNKNOWN_TOPIC_OR_PART` and
`RD_KAFKA_RESP_ERR_TOPIC_AUTHORIZATION_FAILED` to the application through
the standard consumer error (the err field in the message object).
* Consumer will no longer trigger auto creation of topics,
`allow.auto.create.topics=true` may be used to re-enable the old deprecated
functionality.
* The default consumer pre-fetch queue threshold `queued.max.messages.kbytes`
has been decreased from 1GB to 64MB to avoid excessive network usage for low
and medium throughput consumer applications. High throughput consumer
applications may need to manually set this property to a higher value.
* The default consumer Fetch wait time has been increased from 100ms to 500ms
to avoid excessive network usage for low throughput topics.
* If OpenSSL is linked statically, or `ssl.ca.location=probe` is configured,
librdkafka will probe known CA certificate paths and automatically use the
first one found. This should alleviate the need to configure
`ssl.ca.location` when the statically linked OpenSSL's OPENSSLDIR differs
from the system's CA certificate path.
* The heuristics for handling Apache Kafka < 0.10 brokers has been removed to
improve connection error handling for modern Kafka versions.
Users on Brokers 0.9.x or older should already be configuring
`api.version.request=false` and `broker.version.fallback=...` so there
should be no functional change.
* The default producer batch accumulation time, `linger.ms`, has been changed
from 0.5ms to 5ms to improve batch sizes and throughput while reducing
