Memory access issues will be reported on stderr +in real time as they happen (and the test will fail eventually), while +memory leaks will be reported on stderr when the test run exits successfully, +i.e., no tests failed. + +Test failures will typically cause the current test to exit hard without +cleaning up, in which case there will be a large number of reported memory +leaks, these shall be ignored. The memory leak report is only relevant +when the test suite passes. + +**NOTE**: The OSX version of ASAN does not provide memory leak protection, + you will need to run the test suite on Linux (native or in Docker). + +**NOTE**: ASAN, TSAN and valgrind are mutually exclusive. + + +#### Valgrind - memory checker + +Valgrind is a powerful virtual machine that intercepts all memory accesses +of an unmodified program, reporting memory access violations, use after free, +memory leaks, etc. + +Valgrind provides additional checks over ASAN and is mostly useful +for troubleshooting crashes, memory issues and leaks when ASAN falls short. + +To use valgrind, make sure librdkafka and the test suite is built without +ASAN or TSAN, it must be a clean build without any other instrumentation, +then simply run: + + $ ./run-test.sh valgrind + +Valgrind will report to stderr, just like ASAN. + + +**NOTE**: Valgrind only runs on Linux. + +**NOTE**: ASAN, TSAN and valgrind are mutually exclusive. + + +### TSAN - Thread and locking issues + +librdkafka uses a number of internal threads which communicate and share state +through op queues, conditional variables, mutexes and atomics. + +While the docstrings in the librdkafka source code specify what locking is +required it is very hard to manually verify that the correct locks +are acquired, and in the correct order (to avoid deadlocks). + +TSAN, ThreadSanitizer, is of great help here. As with ASAN, TSAN is a +build-time option: run `./dev-conf.sh tsan` to rebuild with TSAN. + +Run the test suite as usual, preferably in parallel. TSAN will output +thread errors to stderr and eventually fail the test run. + +If you're having threading issues and TSAN does not provide enough information +to sort it out, you can also try running the test with helgrind, which +is valgrind's thread checker (`./run-test.sh helgrind`). + + +**NOTE**: ASAN, TSAN and valgrind are mutually exclusive. + + + +# PR and release verification + +Prior to pushing your PR you must verify that your code change has not +introduced any regression or new issues, this requires running the test +suite in multiple different modes: + + * PLAINTEXT, SSL transports + * All SASL mechanisms (PLAIN, GSSAPI, SCRAM, OAUTHBEARER) + * Idempotence enabled for all tests + * With memory checking + * With thread checking + * Compatibility with older broker versions + +These tests must also be run for each release candidate that is created. + + $ make release-test + +This will take approximately 30 minutes. + +**NOTE**: Run this on Linux (for ASAN and Kerberos tests to work properly), not OSX. + + +# Test mode specifics + +The following sections rely on trivup being installed. + + +### Compatbility tests with multiple broker versions + +To ensure compatibility across all supported broker versions the entire +test suite is run in a trivup based cluster, one test run for each +relevant broker version. + + $ ./broker_version_tests.py + + +### SASL tests + +Testing SASL requires a bit of configuration on the brokers, to automate +this the entire test suite is run on trivup based clusters. + + $ ./sasl_tests.py + + + +### Full test suite(s) run + +To run all tests, including the broker version and SASL tests, etc, use + + $ make full + +**NOTE**: `make full` is a sub-set of the more complete `make release-test` target. + + +### Idempotent Producer tests + +To run the entire test suite with `enable.idempotence=true` enabled, use +`make idempotent_seq` or `make idempotent_par` for sequencial or +parallel testing. +Some tests are skipped or slightly modified when idempotence is enabled. + + +## Manual testing notes + +The following manual tests are currently performed manually, they should be +implemented as automatic tests. + +### LZ4 interop + + $ ./interactive_broker_version.py -c ./lz4_manual_test.py 0.8.2.2 0.9.0.1 2.3.0 + +Check the output and follow the instructions. + + + + +## Test numbers + +Automated tests: 0000-0999 +Manual tests: 8000-8999 diff --git a/tests/broker_version_tests.py b/tests/broker_version_tests.py index b25a5e2d67..a1edcca283 100755 --- a/tests/broker_version_tests.py +++ b/tests/broker_version_tests.py @@ -115,7 +115,7 @@ def handle_report (report, version, suite): default=False, help='On test failure start a shell before bringing the cluster down.') parser.add_argument('versions', type=str, nargs='*', -

+querying the broker for supported API request types and versions - +allowing the client to figure out what features it can use. +But for older broker versions there is no way for the client to reliably know +what protocol features the broker supports. + +To alleviate this situation librdkafka has three configuration properties: + * `api.version.request=true|false` - enables the API version request, + this requires a >= 0.10.0.0 broker and will cause a disconnect on + brokers 0.8.x - this disconnect is recognized by librdkafka and on the next + connection attempt (which is immediate) it will disable the API version + request and use `broker.version.fallback` as a basis of available features. + **NOTE**: Due to a bug in broker version 0.9.0.0 & 0.9.0.1 the broker will + not close the connection when receiving the API version request, instead + the request will time out in librdkafka after 10 seconds and it will fall + back to `broker.version.fallback` on the next immediate connection attempt. + * `broker.version.fallback=X.Y.Z.N` - if the API version request fails + (if `api.version.request=true`) or API version requests are disabled + (`api.version.request=false`) then this tells librdkafka what version the + broker is running and adapts its feature set accordingly. + * `api.version.fallback.ms=MS` - In the case where `api.version.request=true` + and the API version request fails, this property dictates for how long + librdkafka will use `broker.version.fallback` instead of + `api.version.request=true`. After `MS` has passed the API version request + will be sent on any new connections made for the broker in question. + This allows upgrading the Kafka broker to a new version with extended + feature set without needing to restart or reconfigure the client + (given that `api.version.request=true`). + +*Note: These properties applies per broker.* + +The API version query was disabled by default (`api.version.request=false`) in +librdkafka up to and including v0.9.5 due to the afforementioned bug in +broker version 0.9.0.0 & 0.9.0.1, but was changed to `true` in +librdkafka v0.11.0. + + +### Supported KIPs + +The [Apache Kafka Implementation Proposals (KIPs)](https://cwiki.apache.org/confluence/display/KAFKA/Kafka+Improvement+Proposals) supported by librdkafka. + + +| KIP | Kafka release | Status | +|--------------------------------------------------------------------------|-------------------------------------------|-----------------------------------------------------------------------------------------------| +| KIP-1 -

The default unsecured token implementation (see https://tools.ietf.org/html/rfc7515#appendix-A.5) recognizes space-separated name=value pairs with valid names including principalClaimName, principal, scopeClaimName, scope, and lifeSeconds. The default value for principalClaimName is "sub", the default value for scopeClaimName is "scope", and the default value for lifeSeconds is 3600. The scope value is CSV format with the default value being no/empty scope. For example: `principalClaimName=azp principal=admin scopeClaimName=roles scope=role1,role2 lifeSeconds=600`. In addition, SASL extensions can be communicated to the broker via `extension_NAME=value`. For example: `principal=admin extension_traceId=123`

*Type: string* transactional.id | P | | | high | Enables the transactional producer. The transactional.id is used to identify the same transactional producer instance across process restarts. It allows the producer to guarantee that transactions corresponding to earlier instances of the same producer have been finalized prior to starting any new transactions, and that any zombie instances are fenced off. If no transactional.id is provided, then the producer is limited to idempotent delivery (if enable.idempotence is set). Requires broker version >= 0.11.0.

The transaction timeout automatically adjusts `message.timeout.ms` and `socket.timeout.ms`, unless explicitly configured in which case they must not exceed the transaction timeout (`socket.timeout.ms` must be at least 100ms lower than `transaction.timeout.ms`). This is also the default timeout value if no timeout (-1) is supplied to the transactional API methods.

Producer instantation will fail if user-supplied configuration is incompatible.
*Type: boolean* enable.gapless.guarantee | P | true, false | false | low | **EXPERIMENTAL**: subject to change or removal. When set to `true`, any error that could result in a gap in the produced message series when a batch of messages fails, will raise a fatal error (ERR__GAPLESS_GUARANTEE) and stop the producer.

This patch removes all traces of shared pointers, and renames the internal rd_kafka_itopic_t type back to the public rd_kafka_topic_t. --- CMakeLists.txt | 2 - configure.self | 2 - dev-conf.sh | 3 - packaging/cmake/config.h.in | 1 - src/rd.h | 80 ---------- src/rdkafka.c | 187 ++++++++--------------- src/rdkafka_broker.c | 90 +++++------ src/rdkafka_broker.h | 2 +- src/rdkafka_cgrp.c | 60 ++++---- src/rdkafka_event.c | 3 +- src/rdkafka_int.h | 14 +- src/rdkafka_interceptor.c | 2 +- src/rdkafka_metadata.c | 20 ++- src/rdkafka_msg.c | 117 ++++++--------- src/rdkafka_msg.h | 6 +- src/rdkafka_msgbatch.h | 2 +- src/rdkafka_msgset_writer.c | 2 +- src/rdkafka_offset.c | 39 ++--- src/rdkafka_op.c | 24 ++- src/rdkafka_op.h | 4 +- src/rdkafka_partition.c | 232 +++++++++++++--------------- src/rdkafka_partition.h | 100 ++++++------ src/rdkafka_queue.c | 16 +- src/rdkafka_request.c | 40 +++-- src/rdkafka_topic.c | 292 +++++++++++++++--------------------- src/rdkafka_topic.h | 93 ++++-------- src/rdkafka_txnmgr.c | 17 +-- 27 files changed, 554 insertions(+), 896 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index ffe347e398..af6a1513ea 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -16,7 +16,6 @@ option(WITHOUT_OPTIMIZATION "Disable optimization" OFF) option(ENABLE_DEVEL "Enable development asserts, checks, etc" OFF) option(ENABLE_REFCNT_DEBUG "Enable refcnt debugging" OFF) -option(ENABLE_SHAREDPTR_DEBUG "Enable sharedptr debugging" OFF) set(TRYCOMPILE_SRC_DIR "${CMAKE_CURRENT_LIST_DIR}/packaging/cmake/try_compile") set(BUILT_WITH "CMAKE") @@ -195,7 +194,6 @@ set(GENERATED_DIR "${CMAKE_CURRENT_BINARY_DIR}/generated") # * WITHOUT_OPTIMIZATION # * ENABLE_DEVEL # * ENABLE_REFCNT_DEBUG -# * ENABLE_SHAREDPTR_DEBUG # * HAVE_ATOMICS_32 # * HAVE_ATOMICS_32_SYNC # * HAVE_ATOMICS_64 diff --git a/configure.self b/configure.self index da33615ac1..91fdef1220 100644 --- a/configure.self +++ b/configure.self @@ -33,8 +33,6 @@ mkl_toggle_option "Development" ENABLE_VALGRIND "--enable-valgrind" "Enable in-c mkl_toggle_option "Development" ENABLE_REFCNT_DEBUG "--enable-refcnt-debug" "Enable refcnt debugging" "n" -mkl_toggle_option "Development" ENABLE_SHAREDPTR_DEBUG "--enable-sharedptr-debug" "Enable sharedptr debugging" "n" - mkl_toggle_option "Feature" ENABLE_LZ4_EXT "--enable-lz4-ext" "Enable external LZ4 library support (builtin version 1.9.2)" "y" mkl_toggle_option "Feature" ENABLE_LZ4_EXT "--enable-lz4" "Deprecated: alias for --enable-lz4-ext" "y" diff --git a/dev-conf.sh b/dev-conf.sh index 8a41c34c3a..84e0992be5 100755 --- a/dev-conf.sh +++ b/dev-conf.sh @@ -105,9 +105,6 @@ OPTS="$OPTS --disable-optimization" # disable cyrus-sasl #OPTS="$OPTS --disable-sasl" -# enable sharedptr debugging -#OPTS="$OPTS --enable-sharedptr-debug" - #enable refcnt debugging #OPTS="$OPTS --enable-refcnt-debug" diff --git a/packaging/cmake/config.h.in b/packaging/cmake/config.h.in index 662a604724..796f8c7a69 100644 --- a/packaging/cmake/config.h.in +++ b/packaging/cmake/config.h.in @@ -1,7 +1,6 @@ #cmakedefine01 WITHOUT_OPTIMIZATION #cmakedefine01 ENABLE_DEVEL #cmakedefine01 ENABLE_REFCNT_DEBUG -#cmakedefine01 ENABLE_SHAREDPTR_DEBUG #cmakedefine01 HAVE_ATOMICS_32 #cmakedefine01 HAVE_ATOMICS_32_SYNC diff --git a/src/rd.h b/src/rd.h index a9c997527d..109e30a86b 100644 --- a/src/rd.h +++ b/src/rd.h @@ -390,86 +390,6 @@ static RD_INLINE RD_UNUSED int rd_refcnt_get (rd_refcnt_t *R) { -#if !ENABLE_SHAREDPTR_DEBUG - -/** - * The non-debug version of shared_ptr is simply a reference counting interface - * without any additional costs and no indirections. - */ - -#define RD_SHARED_PTR_TYPE(STRUCT_NAME,WRAPPED_TYPE) WRAPPED_TYPE - - -#define rd_shared_ptr_get_src(FUNC,LINE,OBJ,REFCNT,SPTR_TYPE) \ - (rd_refcnt_add(REFCNT), (OBJ)) -#define rd_shared_ptr_get(OBJ,REFCNT,SPTR_TYPE) \ - (rd_refcnt_add(REFCNT), (OBJ)) - -#define rd_shared_ptr_obj(SPTR) (SPTR) - -#define rd_shared_ptr_put(SPTR,REF,DESTRUCTOR) \ - rd_refcnt_destroywrapper(REF,DESTRUCTOR) - - -#else - -#define RD_SHARED_PTR_TYPE(STRUCT_NAME, WRAPPED_TYPE) \ - struct STRUCT_NAME { \ - LIST_ENTRY(rd_shptr0_s) link;

The CMake build for Windows was setting options by defining or not defining them, whereas for all other platforms options are defined to 1 or 0 to indicate set or not set. In most code, options are checked with a preprocessor test like `#if OPTION`, where it doesn't matter if OPTION is undefined or set to zero; both approaches omit the code within the `#if`. But c426b31e2 introduced code that requires OPTION to actually be defined to an integral value. This patch ensures that the CMake configuration sets options to 1/0 when targeting Windows. Technically only ENABLE_DEVEL needs to have a 1/0 value, but it seemed more future-proof to apply the change proactively to all options. --- src/CMakeLists.txt | 32 ++++++++++++++++++++++++-------- 1 file changed, 24 insertions(+), 8 deletions(-) diff --git a/src/CMakeLists.txt b/src/CMakeLists.txt index 953002e017..08772a8200 100644 --- a/src/CMakeLists.txt +++ b/src/CMakeLists.txt @@ -114,28 +114,44 @@ endif() if(WITHOUT_WIN32_CONFIG) list(APPEND rdkafka_compile_definitions WITHOUT_WIN32_CONFIG) if(WITH_SSL) - list(APPEND rdkafka_compile_definitions WITH_SSL) + list(APPEND rdkafka_compile_definitions WITH_SSL=1) + else() + list(APPEND rdkafka_compile_definitions WITH_SSL=0) endif(WITH_SSL) if(WITH_ZLIB) - list(APPEND rdkafka_compile_definitions WITH_ZLIB) + list(APPEND rdkafka_compile_definitions WITH_ZLIB=1) + else() + list(APPEND rdkafka_compile_definitions WITH_ZLIB=0) endif(WITH_ZLIB) if(WITH_SNAPPY) - list(APPEND rdkafka_compile_definitions WITH_SNAPPY) + list(APPEND rdkafka_compile_definitions WITH_SNAPPY=1) + else() + list(APPEND rdkafka_compile_definitions WITH_SNAPPY=0) endif(WITH_SNAPPY) if(WITH_ZSTD) - list(APPEND rdkafka_compile_definitions WITH_ZSTD) + list(APPEND rdkafka_compile_definitions WITH_ZSTD=1) + else() + list(APPEND rdkafka_compile_definitions WITH_ZSTD=0) endif(WITH_ZSTD) if(WITH_SASL_SCRAM) - list(APPEND rdkafka_compile_definitions WITH_SASL_SCRAM) + list(APPEND rdkafka_compile_definitions WITH_SASL_SCRAM=1) + else() + list(APPEND rdkafka_compile_definitions WITH_SASL_SCRAM=0) endif(WITH_SASL_SCRAM) if(WITH_SASL_OAUTHBEARER) - list(APPEND rdkafka_compile_definitions WITH_SASL_OAUTHBEARER) + list(APPEND rdkafka_compile_definitions WITH_SASL_OAUTHBEARER=1) + else() + list(APPEND rdkafka_compile_definitions WITH_SASL_OAUTHBEARER=0) endif(WITH_SASL_OAUTHBEARER) if(ENABLE_DEVEL) - list(APPEND rdkafka_compile_definitions ENABLE_DEVEL) + list(APPEND rdkafka_compile_definitions ENABLE_DEVEL=1) + else() + list(APPEND rdkafka_compile_definitions ENABLE_DEVEL=0) endif(ENABLE_DEVEL) if(WITH_PLUGINS) - list(APPEND rdkafka_compile_definitions WITH_PLUGINS) + list(APPEND rdkafka_compile_definitions WITH_PLUGIN=1) + else() + list(APPEND rdkafka_compile_definitions WITH_PLUGIN=0) endif(WITH_PLUGINS) endif() From 8ef7f12379a9a7084491acd683bfb1b3e27f6852 Mon Sep 17 00:00:00 2001 From: Magnus Edenhill Date: Fri, 3 Apr 2020 12:57:43 +0200 Subject: [PATCH 0341/1290] Per-partition OffsetCommit errors were unhandled (fixes #2791) For instance NOT_COORD_FOR_GROUP would not trigger a coordinator query. --- src/rdkafka_request.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/src/rdkafka_request.c b/src/rdkafka_request.c index b16d86dff7..b80e83b7d4 100644 --- a/src/rdkafka_request.c +++ b/src/rdkafka_request.c @@ -943,8 +943,12 @@ rd_kafka_handle_OffsetCommit (rd_kafka_t *rk, /* If all partitions failed use error code * from last partition as the global error. */ - if (offsets && errcnt == partcnt) + if (offsets && errcnt == partcnt) { err = last_ErrorCode;

It allows the producer to guarantee that transactions corresponding to earlier instances of the same producer have been finalized prior to starting any new transactions, and that any zombie instances are fenced off.

If this value is larger than the `transaction.max.timeout.ms` setting in the broker, the init_transactions() call will fail with ERR_INVALID_TRANSACTION_TIMEOUT. The transaction timeout automatically adjusts `message.timeout.ms` and `socket.timeout.ms`, unless explicitly configured in which case they must not exceed the transaction timeout (`socket.timeout.ms` must be at least 100ms lower than `transaction.timeout.ms`). This is also the default timeout value if no timeout (-1) is supplied to the transactional API methods.

The prior behavior required the user to manually inspect the configure output to determine whether the feature was actually enabled. This was particularly problematic with downstream build systems, like Cargo with rust-rdkafka, where the configure output is hidden from users if configuration is successful. The default behavior remains unchanged; if a user does not explicitly request a feature with --enable-XXX nor dis-request it with --disable-XXX, and the feature is enabled by default, then it is not be an error if the feature cannot be found. Note that this commit additionally excludes the `ENABLE_*` options from the confugration summary, as they were misleading. For example, if a user passed --enable-zstd, but zstd was not found on the system, the configuration summary would report "ENABLE_ZSTD y"--merely reporting that the user had requested zstd support, not that zstd support would actually be available in the built library. (If the user does desire that information, they can find it in the BUILT_WITH line, which includes only the features that were actually possible to enable.) --- configure.self | 30

The "add" wrapper preserves the invariant that a known topic should never get added to the desired partitions queue, while the "add0" function does not. Maintaining this invariant is important for rd_kafka_topic_partition_cnt_update, which assumes that a toppar is in either the list of known partitions or the list of desired partitions, but not both. Violating this invariant results in the situation described in #2915, where updating assignments can trigger incorrect "unknown partition" errors. This patch rearranges rd_kafka_toppar_desired_add/add0 so that add0, in addition to add, will avoid adding known partitions to the desired partition list. The enclosed test correctly fails if run against the current master (for the reasons described above).

Add required libraries (zlib, lz4, zstd, openssl, sasl2) to the pkg-config `Requires` field instead of to `Libs` if they were discovered via pkg-config. This allows pkg-config (and other tools built on top of the pkg-config metadata) to see librdkafka's full dependency graph. 2. Prefix full paths to librdkafka.a with the pkg-config variable ${pc_sysrootdir}. pkg-config automatically applies this prefix to paths passed to -I and -L, but nowhere else. This means that the previous link line in the -static.pc files is inconsistent, and would expand to -L${pc_sysrootdir}${libdir} ${libdir}/librdkafka.a 3. #include when checking for sasl so that detection via pkg-config works.

Producer instantation will fail if user-supplied configuration is incompatible.
*Type: boolean* enable.gapless.guarantee | P | true, false | false | low | **EXPERIMENTAL**: subject to change or removal. When set to `true`, any error that could result in a gap in the produced message series when a batch of messages fails, will raise a fatal error (ERR__GAPLESS_GUARANTEE) and stop the producer. Messages failing due to `message.timeout.ms` are not covered by this guarantee. Requires `enable.idempotence=true`.
*Type: boolean* queue.buffering.max.messages | P | 1 .. 10000000 | 100000 | high | Maximum number of messages allowed on the producer queue. This queue is shared by all topics and partitions.

And under this circumstances gcc10 with -O1 -ftree-loop-vectorize (or simply -O3), due to loop unroll, generates code that do copy by 16 bytes at a time for the second loop (MOVDQU+MOVUPS), while this is not correct since the memory may be overlapped and may be changed in the previous iteration. Fix this by eliminating those UB, by using memcpy over direct store/load since these days direct store/loads looks redundant. Even on ARM [1].

polled using the batch queue method, so the consumer will still get old messages. Solution: when assign happens, a new op event with type RD_KAFKA_OP_BARRIER will be created, a new version is been created at mean time. If the consumer met this event, will clean the buffer by comparing the version of msgs and the new version just created. --- src/rdkafka.c | 6 +- src/rdkafka_op.c | 2 + src/rdkafka_op.h | 1 + src/rdkafka_partition.c | 26 ++- src/rdkafka_queue.c | 35 +++- tests/0122-buffer_cleaning_after_rebalance.c | 207 +++++++++++++++++++ tests/CMakeLists.txt | 1 + tests/test.c | 2 + win32/tests/tests.vcxproj | 1 + 9 files changed, 275 insertions(+), 6 deletions(-) create mode 100644 tests/0122-buffer_cleaning_after_rebalance.c diff --git a/src/rdkafka.c b/src/rdkafka.c index 1019c1650d..ec9dbc5940 100644 --- a/src/rdkafka.c +++ b/src/rdkafka.c @@ -2954,7 +2954,8 @@ rd_kafka_consume_cb (rd_kafka_t *rk, struct consume_ctx *ctx = opaque;

The fix is to silently (unless debug) ignore these unsolicited abort markers if they're not in the aborted transaction list and not pop off the next non-matching offset from the aborted transaction list. --- CHANGELOG.md | 8 +++ src/rdkafka_msgset_reader.c | 113 ++++++++++++++++++++++-------------- 2 files changed, 77 insertions(+), 44 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 55308c3018..7e726f0d0a 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -72,6 +72,14 @@ librdkafka v1.7.0 is feature release: * Fix balancing and reassignment issues with the cooperative-sticky assignor. #3306. * Fix incorrect detection of first rebalance in sticky assignor (@hallfox). + * Aborted transactions with no messages produced to a partition could + cause further successfully committed messages in the same Fetch response to + be ignored, resulting in consumer-side message loss. + A log message along the lines `Abort txn ctrl msg bad order at offset + 7501: expected before or at 7702: messages in aborted transactions may be delivered to the application` + would be seen. + This is a rare occurrence where a transactional producer would register with + the partition but not produce any messages before aborting the transaction. * The consumer group deemed cached metadata up to date by checking `topic.metadata.refresh.interval.ms`: if this property was set too low it would cause cached metadata to be unusable and new metadata to be fetched, diff --git a/src/rdkafka_msgset_reader.c b/src/rdkafka_msgset_reader.c index bec8177940..a9d28e4312 100644 --- a/src/rdkafka_msgset_reader.c +++ b/src/rdkafka_msgset_reader.c @@ -81,7 +81,7 @@ static RD_INLINE int64_t rd_kafka_aborted_txns_pop_offset (rd_kafka_aborted_txns_t *aborted_txns, - int64_t pid);

Defaults: On Windows the system's CA certificates are automatically looked up in the Windows Root certificate store. On Mac OSX this configuration defaults to `probe`. It is recommended to install openssl using Homebrew, to provide CA certificates. On Linux install the distribution's ca-certificates package. If OpenSSL is statically linked or `ssl.ca.location` is set to `probe` a list of standard paths will be probed and the first one found will be used as the default CA certificate location path. If OpenSSL is dynamically linked the OpenSSL library's default path will be used (see `OPENSSLDIR` in `openssl version -a`).

These new partition objects, with no + knowledge of previous incarnations, would start counting partition messages + at zero again. + If new messages were produced for these partitions by the same producer + instance, the same message sequence numbers would be sent to the broker. + If the broker still maintains state for the producer's PID and Epoch it could + deem that these messages with reused sequence numbers had already been + written to the log and treat them as legit duplicates. + This would seem to the producer that these new messages were successfully + written to the partition log by the broker when they were in fact discarded + as duplicates, leading to silent message loss. + The fix included in this release is to save the per-partition idempotency + state when a partition is removed, and then recover and use that saved + state if the partition comes back at a later time. + + + # librdkafka v1.8.2 librdkafka v1.8.2 is a maintenance release. diff --git a/src/rdkafka_buf.h b/src/rdkafka_buf.h index 78762036b0..862d9c8db4 100644 --- a/src/rdkafka_buf.h +++ b/src/rdkafka_buf.h @@ -583,6 +583,13 @@ struct rd_kafka_buf_s { /* rd_kafka_buf_t */ } while (0) +#define rd_kafka_buf_peek_i16(rkbuf, of, dstptr) \ + do { \ + int16_t _v; \ + rd_kafka_buf_peek(rkbuf, of, &_v, sizeof(_v)); \ + *(dstptr) = be16toh(_v); \ + } while (0) + #define rd_kafka_buf_read_i16a(rkbuf, dst) \ do { \ int16_t _v; \ diff --git a/src/rdkafka_mock.c b/src/rdkafka_mock.c index 12c4b06781..7c6f891c02 100644 --- a/src/rdkafka_mock.c +++ b/src/rdkafka_mock.c @@ -171,6 +171,124 @@ rd_kafka_mock_msgset_find(const rd_kafka_mock_partition_t *mpart, } +/** + * @brief Looks up or creates a new pidstate for the given partition and PID. + * + * The pidstate is used to verify per-partition per-producer BaseSequences + * for the idempotent/txn producer. + */ +static rd_kafka_mock_pid_t * +rd_kafka_mock_partition_pidstate_get(rd_kafka_mock_partition_t *mpart, + const rd_kafka_mock_pid_t *mpid) { + rd_kafka_mock_pid_t *pidstate; + size_t tidlen; + + pidstate = rd_list_find(&mpart->pidstates, mpid, rd_kafka_mock_pid_cmp); + if (pidstate) + return pidstate; + + tidlen = strlen(mpid->TransactionalId); + pidstate = rd_malloc(sizeof(*pidstate) + tidlen); + pidstate->pid = mpid->pid; + memcpy(pidstate->TransactionalId, mpid->TransactionalId, tidlen); + pidstate->TransactionalId[tidlen] = '\0'; + + pidstate->lo = pidstate->hi = pidstate->window = 0; + memset(pidstate->seq, 0, sizeof(pidstate->seq)); + + rd_list_add(&mpart->pidstates, pidstate); + + return pidstate; +} + + +/** + * @brief Validate ProduceRequest records in \p rkbuf. + * + * @warning The \p rkbuf must not be read, just peek()ed. + * + * This is a very selective validation, currently only: + * - verify idempotency TransactionalId,PID,Epoch,Seq + */ +static rd_kafka_resp_err_t +rd_kafka_mock_validate_records(rd_kafka_mock_partition_t *mpart, + rd_kafka_buf_t *rkbuf, + size_t RecordCount, + const rd_kafkap_str_t *TransactionalId, + rd_bool_t *is_dupd) { + const int log_decode_errors = LOG_ERR; + rd_kafka_mock_cluster_t *mcluster = mpart->topic->cluster; + rd_kafka_mock_pid_t *mpid; + rd_kafka_mock_pid_t *mpidstate = NULL; + rd_kafka_pid_t pid; + int32_t expected_BaseSequence = -1, BaseSequence = -1; + rd_kafka_resp_err_t err; + + *is_dupd = rd_false; + + if (!TransactionalId || RD_KAFKAP_STR_LEN(TransactionalId) < 1) + return RD_KAFKA_RESP_ERR_NO_ERROR; + + rd_kafka_buf_peek_i64(rkbuf, RD_KAFKAP_MSGSET_V2_OF_ProducerId, + &pid.id); + rd_kafka_buf_peek_i16(rkbuf, RD_KAFKAP_MSGSET_V2_OF_ProducerEpoch, + &pid.epoch); + rd_kafka_buf_peek_i32(rkbuf, RD_KAFKAP_MSGSET_V2_OF_BaseSequence, + &BaseSequence); + + mtx_lock(&mcluster->lock); + err = rd_kafka_mock_pid_find(mcluster, TransactionalId, pid, &mpid); + mtx_unlock(&mcluster->lock); + + if (likely(!err)) { + + if (mpid->pid.epoch != pid.epoch) + err = RD_KAFKA_RESP_ERR_INVALID_PRODUCER_EPOCH; + + /* Each partition tracks the 5 last Produce requests per PID.*/ + mpidstate = rd_kafka_mock_partition_pidstate_get(mpart, mpid); + + expected_BaseSequence = mpidstate->seq[mpidstate->hi]; + + /* A BaseSequence within the range of the last 5 requests is + * considered a legal duplicate and will be successfully acked + * but not written to the log. */ + if (BaseSequence < mpidstate->seq[mpidstate->lo]) + err = RD_KAFKA_RESP_ERR_DUPLICATE_SEQUENCE_NUMBER; + else if (BaseSequence > mpidstate->seq[mpidstate->hi]) + err = RD_KAFKA_RESP_ERR_OUT_OF_ORDER_SEQUENCE_NUMBER; + else if (BaseSequence != expected_BaseSequence) + *is_dupd = rd_true; + } + + if (unlikely(err)) { + rd_kafka_dbg(mcluster->rk, MOCK, "MOCK", + "Broker %" PRId32 ": Log append %s [%" PRId32 + "] failed: PID mismatch: TransactionalId=%.*s " + "expected %s BaseSeq %" PRId32 + ", not %s BaseSeq %" PRId32 ": %s", + mpart->leader->id, mpart->topic->name, mpart->id, + RD_KAFKAP_STR_PR(TransactionalId), + mpid ?

(#3966) Returning a `const string` means "My caller can have a copy of this string, but they aren't allowed to modify it" -- for example, they aren't allowed to use move semantics to move-out-of the returned string. Thus `x = y.name();` will use copy assignment rather than move assignment. This is a needless pessimization in C++11 and later.

This solves the following problem: The property "allow.auto.create.topics" is supposed to be a consumer property, but we are setting it (and it is affecting the behaviour of) both the consumer and producer. It gives a warning if we change it in the producer, but works nevertheless. (the default value for the producer is true) One of the effects is that if a user is using their producer as an adminclient, a call to get metadata for a topic might create that topic, and if the user specifies allow.auto.create.topics, then they get a warning. Unfortunately, we even recommend using a producer with the above setting (see INTRODUCTION.md). A knock on effect is that both the go and python clients use a producer internally for their adminclients so the user has to either live with a call to GetMetadata creating topics, or with the warning. The java client only allows this property to be set on the consumer, which makes it more confusing. --- CHANGELOG.md | 2 ++ CONFIGURATION.md | 2 +- src/rdkafka_conf.c | 26 ++++++++++++++------------ 3 files changed, 17 insertions(+), 13 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index f246c988e8..a698e993b6 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -42,6 +42,8 @@ configuration property. * Bundled zlib upgraded to version 1.2.13. * Added `on_broker_state_change()` interceptor * The C++ API no longer returns strings by const value, which enables better move optimization in callers. + * 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. ## Fixes diff --git a/CONFIGURATION.md b/CONFIGURATION.md index 907737f3de..641c9271e5 100644 --- a/CONFIGURATION.md +++ b/CONFIGURATION.md @@ -57,6 +57,7 @@ api.version.request | * | true, false | true api.version.request.timeout.ms | * | 1 .. 300000 | 10000 | low | Timeout for broker API version requests.

The transaction timeout automatically adjusts `message.timeout.ms` and `socket.timeout.ms`, unless explicitly configured in which case they must not exceed the transaction timeout (`socket.timeout.ms` must be at least 100ms lower than `transaction.timeout.ms`). This is also the default timeout value if no timeout (-1) is supplied to the transactional API methods.

In case compression is enabled, we "inflate" the batch size by 8x for the purposes of this check. At least, that's the intent. Currently the condition is reversed: the 8x inflation happens if compression is disabled, not the other way around. The effect is that messages linger for longer than expected in the queue, as if the batch size was 8x larger. They are still sent respecting the batch size however, since this occurs at a different location. This change removes the 8x inflation entirely: instead we use the batch size as the threshold regardless of whether compression is enabled per the discussion on the PR.

When provided, librdkafka invokes the callback when resolving the address of a Kafka broker instead of calling `getaddrinfo` directly. The callback is expected to function exactly as `getaddrinfo`, except that it is additional provided with the `opaque` value. The callback will enable tunneling to a Kafka broker (e.g., via SSH or AWS PrivateLink). The broker addresses returned by the bootstrap protocol will not be directly routable from the client; the address resolution callback allows the end user to rewrite the broker addresses as appropriate for the tunnel. --- CHANGELOG.md | 2 +- CONFIGURATION.md | 1 + src/rdaddr.c | 39 +++++--- src/rdaddr.h | 23 +++-- src/rdkafka.h | 29 ++++++ src/rdkafka_broker.c | 9 +- src/rdkafka_conf.c | 12 +++ src/rdkafka_conf.h | 7 ++ tests/0136-resolve_cb.c | 181 ++++++++++++++++++++++++++++++++++++++ tests/CMakeLists.txt | 1 + tests/test.c | 2 + win32/tests/tests.vcxproj | 1 + 12 files changed, 285 insertions(+), 22 deletions(-) create mode 100644 tests/0136-resolve_cb.c diff --git a/CHANGELOG.md b/CHANGELOG.md index 165e006729..95c5383340 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -45,7 +45,7 @@ configuration property. * 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.

There is no way for a static library + to express link dependencies, so there will also be `rdkafka-static.pc` + pkg-config file generated that contains linker flags for the external + dependencies. + Those external dependencies are however most likely only available on the + build host, so this static library is not particularily useful for + repackaging purposes (such as for high-level clients using librdkafka). + + * a self-contained static-library (`librdkafka-static.a`) which attempts + to contain static versions of all external dependencies, effectively making + it possible to link just with `librdkafka-static.a` to get all + dependencies needed. + Since the state of static libraries in the various distro and OS packaging + systems is of varying quality and availability, it is usually not possible + for the librdkafka build system (mklove) to generate this completely + self-contained static library simply using dependencies available on the + build system, and the make phase of the build will emit warnings when it + can't bundle all external dependencies due to this. + To circumvent this problem it is possible for the build system (mklove) + to download and build static libraries of all needed external dependencies, + which in turn allows it to create a complete bundle of all dependencies. + This results in a `librdkafka-static.a` that has no external dependecies + other than the system libraries (libc, pthreads, rt, etc). + To achieve this you will need to pass + `--install-deps --source-deps-only --enable-static` to + librdkafka's `./configure`. + + * `rdkafka.pc` and `rdkafka-static.pc` pkg-config files that tells + applications and libraries that depend on librdkafka what external + dependencies are needed to successfully link with librdkafka. + This is mainly useful for the dynamic librdkafka librdkafka + (`librdkafka.so.1` or `librdkafka.1.dylib` on OSX). + + +**NOTE**: Due to libsasl2/cyrus-sasl's dynamically loaded plugins, it is +not possible for us to provide a self-contained static library with +GSSAPI/Kerberos support. + + + +### The artifact pipeline + +We rely solely on CI systems to build our artifacts; no artifacts must be built +on a non-CI system (e.g., someones work laptop, some random ec2 instance, etc). + +The reasons for this are: + + 1. Reproducible builds: we want a well-defined environment that doesn't change + (too much) without notice and that we can rebuild artifacts on at a later + time if required. + 2. Security; these CI systems provide at least some degree of security + guarantees, and they're managed by people who knows what they're doing + most of the time. This minimizes the risk for an artifact to be silently + compromised due to the developer's laptop being hacked. + 3.

Top achieve this, blocked the timer using rd_kafka_app_poll_blocking, and reset it at the end of the call. This doesn't work correctly in the cases where we're simply polling an unrelated queue, like the log queue. In that case, just by polling the log queue, the timer is reset, despite us not actually consuming anything (or doing any consume poll). At the same time, it's a reasonable expectation that max.poll.interval.ms won't be triggered while we are doing any sort of consumer poll. This commit takes care of both the cases. The methods (from public API) which block/reset the timer are: rd_kafka_consume_batch rd_kafka_consume_batch_queue rd_kafka_consume_callback rd_kafka_consume_callback_queue rd_kafka_consume rd_kafka_consumer_poll --- CHANGELOG.md | 2 + src/rdkafka.c | 15 --- tests/0089-max_poll_interval.c | 180 ++++++++++++++++++++++++++++++++- 3 files changed, 178 insertions(+), 19 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 9711f9ba2f..ca4e189448 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -5,6 +5,8 @@ librdkafka v2.0.3 is a bugfix release: * 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. +* Fix an issue with `max.poll.interval.ms`, where polling any queue would cause + the timeout to be reset (#4176). ## Fixes diff --git a/src/rdkafka.c b/src/rdkafka.c index 8eedd9f94b..c80c9feed9 100644 --- a/src/rdkafka.c +++ b/src/rdkafka.c @@ -3974,14 +3974,9 @@ rd_kafka_op_res_t rd_kafka_poll_cb(rd_kafka_t *rk, int rd_kafka_poll(rd_kafka_t *rk, int timeout_ms) { int r;

It was changed it so that only certain rdkafka.h functions which were polling would reset the timer. However, librdkafka exposes a method rd_kafka_queue_get_consumer, which returns the consumer queue, and the application can poll this queue for events rather than calling consume poll. There is no way to distinguish polls to this queue and an arbitrary queue, and it won't reset the timer. So, a new flag is maintained inside the queue denoting if it might contain fetched messages, or not. It deals with forwarding of queues, so if a queue which receives fetched messages is forwarded multiple times, calling poll on the forwardee will also reset the timer. --------- Co-authored-by: Emanuele Sabellico --- CHANGELOG.md | 8 +++- src/rdkafka.c | 25 ++++++++++ src/rdkafka.h | 6 +++ src/rdkafka_cgrp.c | 2 +- src/rdkafka_partition.c | 2 +- src/rdkafka_queue.c | 44 ++++++++++++++++- src/rdkafka_queue.h | 35 ++++++++++++-- tests/0089-max_poll_interval.c | 87 ++++++++++++++++++++++++++++++++++ 8 files changed, 201 insertions(+), 8 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 04d363d682..328f45a245 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -12,6 +12,8 @@ librdkafka v2.1.1 is a maintenance release: timeout.

These types of errors can happen it the other side doesn't support `close_notify` or if there's a TCP connection reset. ### Consumer fixes diff --git a/src/rdkafka_offset.c b/src/rdkafka_offset.c index 2cdcd7aa3c..fd76f138d2 100644 --- a/src/rdkafka_offset.c +++ b/src/rdkafka_offset.c @@ -998,10 +998,8 @@ static void rd_kafka_toppar_handle_OffsetForLeaderEpoch(rd_kafka_t *rk, &rk->rk_timers, &rktp->rktp_validate_tmr, rd_false, 500 * 1000 /* 500ms */, rd_kafka_offset_validate_tmr_cb, rktp); - goto done; - } - if (!(actions & RD_KAFKA_ERR_ACTION_REFRESH)) { + } else if (actions & RD_KAFKA_ERR_ACTION_PERMANENT) { /* Permanent error */ rd_kafka_offset_reset( rktp, rd_kafka_broker_id(rkb), diff --git a/src/rdkafka_request.c b/src/rdkafka_request.c index 1302e74d41..132f2c01f1 100644 --- a/src/rdkafka_request.c +++ b/src/rdkafka_request.c @@ -134,6 +134,7 @@ int rd_kafka_err_action(rd_kafka_broker_t *rkb, break; case RD_KAFKA_RESP_ERR__TRANSPORT: + case RD_KAFKA_RESP_ERR__SSL: case RD_KAFKA_RESP_ERR__TIMED_OUT: case RD_KAFKA_RESP_ERR_REQUEST_TIMED_OUT: case RD_KAFKA_RESP_ERR_NOT_ENOUGH_REPLICAS_AFTER_APPEND: diff --git a/src/rdkafka_ssl.c b/src/rdkafka_ssl.c index 9961a240f7..f9c9aee469 100644 --- a/src/rdkafka_ssl.c +++ b/src/rdkafka_ssl.c @@ -1722,6 +1722,14 @@ int rd_kafka_ssl_ctx_init(rd_kafka_t *rk, char *errstr, size_t errstr_size) { goto fail; +#ifdef SSL_OP_IGNORE_UNEXPECTED_EOF + /* Ignore unexpected EOF error in OpenSSL 3.x, treating + * it like a normal connection close even if + * close_notify wasn't received. + * see issue #4293 */ + SSL_CTX_set_options(ctx, SSL_OP_IGNORE_UNEXPECTED_EOF); +#endif + SSL_CTX_set_mode(ctx, SSL_MODE_ENABLE_PARTIAL_WRITE); rk->rk_conf.ssl.ctx = ctx; diff --git a/tests/0139-offset_validation_mock.c b/tests/0139-offset_validation_mock.c index 3fff5277a4..d1619634b1 100644 --- a/tests/0139-offset_validation_mock.c +++ b/tests/0139-offset_validation_mock.c @@ -138,6 +138,80 @@ static void do_test_no_duplicates_during_offset_validation(void) { SUB_TEST_PASS(); } + +/** + * @brief Test that an SSL error doesn't cause an offset reset. + * See issue #4293. + */ +static void do_test_ssl_error_retried(void) { + rd_kafka_mock_cluster_t *mcluster; + rd_kafka_conf_t *conf; + const char *bootstraps; + const char *topic = test_mk_topic_name(__FUNCTION__, 1); + const char *c1_groupid = topic; + rd_kafka_t *c1; + rd_kafka_topic_partition_list_t *rktpars; + rd_kafka_topic_partition_t *rktpar; + int msg_count = 5; + uint64_t testid = test_id_generate(); + + SUB_TEST_QUICK(); + + mcluster = test_mock_cluster_new(3, &bootstraps); + rd_kafka_mock_topic_create(mcluster, topic, 1, 1); + + /* Seed the topic with messages */ + test_produce_msgs_easy_v(topic, testid, 0, 0, msg_count, 10, + "bootstrap.servers", bootstraps, + "batch.num.messages", "1", NULL); + + /* Make OffsetForLeaderEpoch fail with the _SSL error */ + rd_kafka_mock_push_request_errors(mcluster, + RD_KAFKAP_OffsetForLeaderEpoch, 1, + RD_KAFKA_RESP_ERR__SSL); + + test_conf_init(&conf, NULL, 60); + + test_conf_set(conf, "bootstrap.servers", bootstraps); + test_conf_set(conf, "topic.metadata.refresh.interval.ms", "5000"); + test_conf_set(conf, "auto.offset.reset", "latest"); + test_conf_set(conf, "enable.auto.commit", "false"); + test_conf_set(conf, "enable.auto.offset.store", "false"); + test_conf_set(conf, "enable.partition.eof", "true"); + + c1 = test_create_consumer(c1_groupid, NULL, conf, NULL); + test_consumer_subscribe(c1, topic); + + /* EOF because of reset to latest */ + test_consumer_poll("MSG_EOF", c1, testid, 1, 0, 0, NULL); + + rd_kafka_mock_partition_set_leader(mcluster, topic, 0, 2); + + /* Seek to 0 for validating the offset. */ + rktpars = rd_kafka_topic_partition_list_new(1); + rktpar = rd_kafka_topic_partition_list_add(rktpars, topic, 0); + rktpar->offset = 0; + + /* Will validate the offset at start fetching again + * from offset 0. */ + rd_kafka_topic_partition_set_leader_epoch(rktpar, 0); + rd_kafka_seek_partitions(c1, rktpars, -1); + rd_kafka_topic_partition_list_destroy(rktpars); + + /* Read all messages after seek to zero. + * In case of permanent error instead it reset to latest and + * gets an EOF. */ + test_consumer_poll("MSG_ALL", c1, testid, 0, 0, 5, NULL); + + rd_kafka_destroy(c1); + + test_mock_cluster_destroy(mcluster); + + TEST_LATER_CHECK(); + SUB_TEST_PASS(); +} + + int main_0139_offset_validation_mock(int argc, char **argv) { if (test_needs_auth()) { @@ -147,5 +221,7 @@ int main_0139_offset_validation_mock(int argc, char **argv) { do_test_no_duplicates_during_offset_validation(); + do_test_ssl_error_retried(); + return 0; } From 865cf605094aef6ab98528b1d614ec2c7ec87b5b Mon Sep 17 00:00:00 2001 From: Milind L Date: Wed, 14 Jun 2023 18:13:19 +0530 Subject: [PATCH 1199/1290] Add broker reauthentication [KIP-368] (#4301) Here's how we're doing the reauthentication: 1. In case we get a non-zero `session_lifetime_ms` in the SaslAuthenticate response for a broker `rkb`, start a timer for that broker at 90% of that. 2. [main thread] The timer is hit and the callback triggered. The callback enqueues an op on the broker `rkb`. 3. [broker thread] We get this op in `rd_kafka_broker_op_serve`, and we set max_inflight request to 1, and change the broker state into one of reauth. 4. [broker thread] When we encounter the reauth state in `rd_kafka_broker_thread_main`, we do some cleanup for the preexisting SASL state, and just do Auth exactly the same as the normal way (when we do it the first time around). This takes care of resetting max_inflight to the correct value, too. As the KIP and the discussion in #3754 points out, we can't send anything between the auth requests. Setting max_inflight to 1 means that only one request may be in flight, and since the Sasl* requests have a high priority in the queue (RD_KAFKA_PRIO_FLASH), they will actually hold the other requests back till authentication is complete. Setting it to 1 also means that any requests already in flight will await responses before the auth sequence starts. For OAUTHBEARER, the token itself has an expiry time. There are two cases here: 1. broker's connections.max.reauth.ms > time left to token's expiry: In this case, the session_lifetime_ms in the SaslAuthenticate response is set to the time left for the token's expiry. Since our OAUTHBEARER callback runs at 80% of (time left to token's expiry) and our reauth runs at 90% of (time left to token's expiry), we'll refresh the token before the reauth. It's somewhat trickier than that, because `next_token_refresh_time := client_time + 0.8*(token_expiry - client_time)` and `reauth_time := client_time + 0.9*session_lifetime_ms`. Since session_lifetime_ms is calculated on the server, it might have some drift between the clocks, as well as well as discount the time it takes for the communication between the client/server. But it's expected that even if `token_expiry - client_time != session_lifetime_ms`, the 0.8/0.9 factors will make up for it, as typical token refresh/re-authentication times are on the order of hours (and not seconds). 2. broker's connections.max.reauth.ms < time left to token's expiry: The broker returns connections.max.reauth.ms as the session_lifetime_ms. Since the token has a later expiry, we just use the same token to reauthenticate. --------- Co-authored-by: Victoria Wu Co-authored-by: Emanuele Sabellico --- CHANGELOG.md | 3 + INTRODUCTION.md | 4 +- src/rdkafka_broker.c | 98 +++++- src/rdkafka_broker.h | 12 + src/rdkafka_feature.c | 2 +- src/rdkafka_op.c | 10 +- src/rdkafka_op.h | 1 + src/rdkafka_request.c | 18 + src/rdkafka_request.h | 1 + src/rdkafka_sasl.c | 5 + src/rdkafka_sasl_cyrus.c | 1 + src/rdkafka_sasl_oauthbearer.c | 19 +- src/rdkafka_sasl_scram.c | 1 + src/rdkafka_sasl_win32.c | 1 + src/rdkafka_transport.c | 1 + tests/0142-reauthentication.c | 495 ++++++++++++++++++++++++++++ tests/CMakeLists.txt | 1 + tests/interactive_broker_version.py | 27 +- tests/test.c | 92 +++++- tests/test.h | 4 + win32/tests/tests.vcxproj | 1 + 21 files changed, 772 insertions(+), 25 deletions(-) create mode 100644 tests/0142-reauthentication.c diff --git a/CHANGELOG.md b/CHANGELOG.md index 82d1781a52..7523d3313a 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -12,6 +12,9 @@ librdkafka v2.2.0 is a feature release: (#4184, #4291, #4252). * Fix several bugs with sticky assignor in case of partition ownership changing between members of the consumer group (#4252). + * [KIP-368](https://cwiki.apache.org/confluence/display/KAFKA/KIP-368%3A+Allow+SASL+Connections+to+Periodically+Re-Authenticate): + Allow SASL Connections to Periodically Re-Authenticate + (#4301, started by @vctoriawu). * Avoid treating an OpenSSL error as a permanent error and treat unclean SSL closes as normal ones (#4294). diff --git a/INTRODUCTION.md b/INTRODUCTION.md index 000e454156..67504dd133 100644 --- a/INTRODUCTION.md +++ b/INTRODUCTION.md @@ -1917,7 +1917,7 @@ The [Apache Kafka Implementation Proposals (KIPs)](https://cwiki.apache.org/conf | KIP-359 - Producer: use EpochLeaderId | 2.4.0 | Not supported | | KIP-360 - Improve handling of unknown Idempotent Producer | 2.5.0 | Supported | | KIP-361 - Consumer: add config to disable auto topic creation | 2.3.0 | Supported | -| KIP-368 - SASL periodic reauth | 2.2.0 | Not supported | +| KIP-368 - SASL periodic reauth | 2.2.0 | Supported | | KIP-369 - Always roundRobin partitioner | 2.4.0 | Not supported | | KIP-389 - Consumer group max size | 2.2.0 | Supported (error is propagated to application, but the consumer does not raise a fatal error) | | KIP-392 - Allow consumers to fetch from closest replica | 2.4.0 | Supported | @@ -1996,7 +1996,7 @@ release of librdkafka. | 28 | TxnOffsetCommit | 3 | 3 | | 32 | DescribeConfigs | 4 | 1 | | 33 | AlterConfigs | 2 | 1 | -| 36 | SaslAuthenticate | 2 | 0 | +| 36 | SaslAuthenticate | 2 | 1 | | 37 | CreatePartitions | 3 | 0 | | 42 | DeleteGroups | 2 | 1 | | 47 | OffsetDelete | 0 | 0 | diff --git a/src/rdkafka_broker.c b/src/rdkafka_broker.c index e8fc27b111..cb319aec11 100644 --- a/src/rdkafka_broker.c +++ b/src/rdkafka_broker.c @@ -79,9 +79,9 @@ static const int rd_kafka_max_block_ms = 1000;

*Type: integer* +retry.backoff.ms | P | 1 .. 300000 | 100 | medium | The backoff time in milliseconds before retrying a protocol request, this is the first backoff time, and will be backed off exponentially until number of retries is exhausted, and it's capped by retry.backoff.max.ms.
*Type: integer* +retry.backoff.max.ms | P | 1 .. 300000 | 1000 | medium | The max backoff time in milliseconds before retrying a protocol request, this is the atmost backoff allowed for exponentially backed off requests.
*Type: integer* queue.buffering.backpressure.threshold | P | 1 .. 1000000 | 1 | low | The threshold of outstanding not yet transmitted broker requests needed to backpressure the producer's message accumulator. If the number of not yet transmitted requests equals or exceeds this number, produce request creation that would have otherwise been triggered (for example, in accordance with linger.ms) will be delayed. A lower number yields larger and more effective batches. A higher value can improve latency when using compression on slow machines.
*Type: integer* compression.codec | P | none, gzip, snappy, lz4, zstd | none | medium | compression codec to use for compressing message sets. This is the default value for all topics, may be overridden by the topic configuration property `compression.codec`.
*Type: enum value* compression.type | P | none, gzip, snappy, lz4, zstd | none | medium | Alias for `compression.codec`: compression codec to use for compressing message sets. This is the default value for all topics, may be overridden by the topic configuration property `compression.codec`.

*Type: string* coordinator.query.interval.ms | C | 1 .. 3600000 | 600000 | low | How often to query for the current client group coordinator.

*Type: integer* max.poll.interval.ms | C | 1 .. 86400000 | 300000 | high | Maximum allowed time between calls to consume messages (e.g., rd_kafka_consumer_poll()) for high-level consumers. If this interval is exceeded the consumer is considered failed and the group will rebalance in order to reassign the partitions to another consumer group member. Warning: Offset commits may be not possible at this point. Note: It is recommended to set `enable.auto.offset.store=false` for long-time processing applications and then explicitly store offsets (using offsets_store()) *after* message processing, to make sure offsets are not auto-committed prior to processing has finished. The interval is checked two times per second. See KIP-62 for more information.
*Type: integer* enable.auto.commit | C | true, false | true | high | Automatically and periodically commit offsets in the background. Note: setting this to false does not prevent the consumer from fetching previously committed start offsets. To circumvent this behaviour set specific start offsets per partition in the call to assign().

Separate it out from to the topic partition branch - Added metadata response flow with rko - Updated OffsetFetch to v9 - Removed unrequred fields from ConsumerGroupHeartbeat API to make it work with AK > 3.6 - OffsetFetch working fine. Able to consume. - Changed subsribed list to use correct field - Fixed few memory leaks - Some more memory leak fixes. Added updation to subscribed topics list - Minor changes - [KIP-848] Added new configs group.protocol and group.remote.assignor (#4414) - Added new configs group.protocol and group.remote.assignor - Removed printfs and Updated hardcoded one topic for metadata request - Removed some changes related to removed changes in the protocols - [KIP-848] Added topic id to topic_partition_t while reading from buffer (#4416) - Updating topic name from metadata response for all the requested topic_ids instead of just 1. - Style fixes and fixed skip tag issue in buf_*_topic_partition - Changed variable for next assignment - Added topic name while reading topic partition buffer - Changed variable name from assignments to assignment --- CONFIGURATION.md | 4 +- examples/consumer.c | 14 ++ src/rdkafka_admin.c | 12 +- src/rdkafka_assignment.c | 3 +- src/rdkafka_assignor.c | 4 +- src/rdkafka_buf.c | 2 + src/rdkafka_buf.h | 6 +- src/rdkafka_cgrp.c | 294 ++++++++++++++++++++++++++++++++-- src/rdkafka_cgrp.h | 13 ++ src/rdkafka_metadata.c | 43 ++--- src/rdkafka_partition.c | 21 ++- src/rdkafka_partition.h | 14 ++ src/rdkafka_proto.h | 22 +++ src/rdkafka_protocol.h | 3 +- src/rdkafka_request.c | 284 +++++++++++++++++++++++++------- src/rdkafka_request.h | 30 +++- src/rdkafka_sticky_assignor.c | 3 +- src/rdkafka_txnmgr.c | 5 +- src/rdlist.h | 1 - 19 files changed, 666 insertions(+), 112 deletions(-) diff --git a/CONFIGURATION.md b/CONFIGURATION.md index 1d4bd948b3..e76b73ff7b 100644 --- a/CONFIGURATION.md +++ b/CONFIGURATION.md @@ -1,7 +1,7 @@ # Configuration properties ## Global configuration properties -Property | C/P | Range | Default | Importance | Description +Property | C/P | Range | Default | Importance | Description -----------------------------------------|-----|-----------------|--------------:|------------| -------------------------- builtin.features | * | | gzip, snappy, ssl, sasl, regex, lz4, sasl_gssapi, sasl_plain, sasl_scram, plugins, zstd, sasl_oauthbearer, http, oidc | low | Indicates the builtin features for this build of librdkafka.

By default, set to double the time of linger.ms. To disable sticky behavior, set to 0. This behavior affects messages with the key NULL in all cases, and messages with key lengths of zero when the consistent_random partitioner is in use. These messages would otherwise be assigned randomly. A higher value allows for more effective batching of these messages.
*Type: integer* client.dns.lookup | * | use_all_dns_ips, resolve_canonical_bootstrap_servers_only | use_all_dns_ips | low | Controls how the client uses DNS lookups. By default, when the lookup returns multiple IP addresses for a hostname, they will all be attempted for connection before the connection is considered failed. This applies to both bootstrap and advertised servers. If the value is set to `resolve_canonical_bootstrap_servers_only`, each entry will be resolved and expanded into a list of canonical names. **WARNING**: `resolve_canonical_bootstrap_servers_only` must only be used with `GSSAPI` (Kerberos) as `sasl.mechanism`, as it's the only purpose of this configuration value. **NOTE**: Default here is different from the Java client's default behavior, which connects only to the first IP address returned for a hostname.
