So now you can actually safely mix policies in any combination. If it finds that Key has policies with the same ACL, it will merge them together. So now it is possible to have one "read" policy (with permissions per path/method), second "write" policy, and you can mix them together, just by assigning multiple policies to the key.

Additionally refactored all code related to how we start a web server, in particular now you can run multiple APIs on different ports, and Tyk will dynamically open or close port listeners. Added 2 new fields to API definition: `listen_port` and `protocol`. Valid protocol values: "", "http", "https", "tcp", "tls". By default, protocol is selected based on `http_server_options.use_ssl`, and can be either http or https. Additionally in order to tell that your upstream should be `tcp` or `tls` one, in target URL you can specify protocol like this: "tls://upstream:". So you can have GW listening on TLS, but pointing to TCP upstreaming, or the other way. Example service description: ``` "listen_port": 30001, "protocol": "tls", "certificate": [""], "proxy": { "target_url": "tls://upstream:9191" } ``` All the TLS related features, like mutual TLS or certificate pinning work as expected. Adding "listen_port", means that you can now start HTTPS server on one port, HTTP on another port, and some TCP services on another port as well. The only requirement that each port should serve the same protocol (GW has checks preventing it). Additionally, TCP proxying, support multiplexing based on SNI information, e.g. you can serve multiple TCP services on different domains, pointing to different upstream. - [x] Analytics support - [x] ~Way to specific fixed ports and protocols they are support~Way to specific fixed ports and protocols they don't support -

Most of CPython glue code was moved and simplified into its own package (`dlpython` directory). - The dynamic Python loader uses `python-config` to find available Python versions in the system, the latest version is selected by default. - If the user wants to override a specific version, it's possible to set `python_version` under `coprocess_options`, specifying `3.7` for example. - By default, when using `go build`, the resulting binary will support Python and gRPC. Python will be loaded only when it's available in the system and a Python plugin is used. - The Lua build has its own build tag: `go build -tags 'lua'`. - It's possible to have multiple APIs using different types of plugins at the same time, e.g. API 1 with a gRPC plugin and API 2 with Python. --- .travis.yml | 1 + bin/ci-test.sh | 12 +- cli/linter/schema.json | 3 + config/config.go | 1 + .../{grpc_dispatcher.go => dispatcher.go} | 9 - coprocess/grpc/coprocess_grpc_test.go | 3 - coprocess/native_dispatcher.go | 46 - coprocess/proto/stuff/coprocess_common_pb2.py | 111 -- .../proto/stuff/coprocess_common_pb2_grpc.py | 3 - .../coprocess_mini_request_object_pb2.py | 403 ------ .../coprocess_mini_request_object_pb2_grpc.py | 3 - coprocess/proto/stuff/coprocess_object_pb2.py | 311 ---- .../proto/stuff/coprocess_object_pb2_grpc.py | 63 - .../stuff/coprocess_return_overrides_pb2.py | 131 -- .../coprocess_return_overrides_pb2_grpc.py | 3 - .../stuff/coprocess_session_state_pb2.py | 651 --------- .../stuff/coprocess_session_state_pb2_grpc.py | 3 - coprocess/proto/stuff/server.py | 29 - .../coprocess_id_extractor_python_test.go | 25 +- coprocess/python/coprocess_python_test.go | 22 +- coprocess/python/dispatcher.py | 18 +- coprocess/python/gateway.py | 38 - coprocess/python/tyk/gateway.py | 33 + coprocess/python/tyk/gateway_wrapper.c | 78 - coprocess/python/tyk/gateway_wrapper.h | 8 - coprocess/python/tyk/middleware.py | 1 + coprocess/sds/sds.c | 1277 ----------------- coprocess/sds/sds.h | 273 ---- coprocess/sds/sdsalloc.h | 42 - dlpython/binding.go | 278 ++++ dlpython/helpers.go | 165 +++ dlpython/main.go | 183 +++ dlpython/main_test.go | 50 + dlpython/test_helpers.go | 19 + gateway/api_loader.go | 2 +- gateway/coprocess.go | 129 +- gateway/coprocess_api.go | 13 - gateway/coprocess_bundle.go | 20 +- gateway/coprocess_bundle_test.go | 2 - gateway/coprocess_dummy.go | 87 -- gateway/coprocess_events.go | 7 +- gateway/coprocess_grpc.go | 41 +- gateway/coprocess_helpers.go | 2 - gateway/coprocess_lua.go | 60 +- gateway/coprocess_native.go | 85 -- gateway/coprocess_python.go | 391 +++-- gateway/coprocess_python_api.c | 78 - gateway/coprocess_testutil.go | 182 --- gateway/event_system.go | 5 +- gateway/sds.c | 1277 ----------------- gateway/server.go | 6 +- gateway/testutil.go | 1 - 52 files changed, 1098 insertions(+), 5586 deletions(-) rename coprocess/{grpc_dispatcher.go => dispatcher.go} (91%) delete mode 100644 coprocess/native_dispatcher.go delete mode 100644 coprocess/proto/stuff/coprocess_common_pb2.py delete mode 100644 coprocess/proto/stuff/coprocess_common_pb2_grpc.py delete mode 100644 coprocess/proto/stuff/coprocess_mini_request_object_pb2.py delete mode 100644 coprocess/proto/stuff/coprocess_mini_request_object_pb2_grpc.py delete mode 100644 coprocess/proto/stuff/coprocess_object_pb2.py delete mode 100644 coprocess/proto/stuff/coprocess_object_pb2_grpc.py delete mode 100644 coprocess/proto/stuff/coprocess_return_overrides_pb2.py delete mode 100644 coprocess/proto/stuff/coprocess_return_overrides_pb2_grpc.py delete mode 100644 coprocess/proto/stuff/coprocess_session_state_pb2.py delete mode 100644 coprocess/proto/stuff/coprocess_session_state_pb2_grpc.py delete mode 100644 coprocess/proto/stuff/server.py delete mode 100644 coprocess/python/gateway.py create mode 100644 coprocess/python/tyk/gateway.py delete mode 100644 coprocess/python/tyk/gateway_wrapper.c delete mode 100644 coprocess/python/tyk/gateway_wrapper.h delete mode 100644 coprocess/sds/sds.c delete mode 100644 coprocess/sds/sds.h delete mode 100644 coprocess/sds/sdsalloc.h create mode 100644 dlpython/binding.go create mode 100644 dlpython/helpers.go create mode 100644 dlpython/main.go create mode 100644 dlpython/main_test.go create mode 100644 dlpython/test_helpers.go delete mode 100644 gateway/coprocess_dummy.go delete mode 100644 gateway/coprocess_native.go delete mode 100644 gateway/coprocess_python_api.c delete mode 100644 gateway/coprocess_testutil.go delete mode 100644 gateway/sds.c diff --git a/.travis.yml b/.travis.yml index 3d8be76628e..77ca1c0f4f4 100644 --- a/.travis.yml +++ b/.travis.yml @@ -14,6 +14,7 @@ addons: packages: - python3.5 - python3-pip + - python3.5-dev - libluajit-5.1-dev matrix: diff --git a/bin/ci-test.sh b/bin/ci-test.sh index 883563f096c..c50ad319537 100755 --- a/bin/ci-test.sh +++ b/bin/ci-test.sh @@ -33,10 +33,12 @@ if [[ ${LATEST_GO} ]];

This helps to avoid tedious specifying each possible ports. Example ```json { "ports_whitelist": { "http": { "ranges": [ { "from": 8000, "to": 9000 } ] } } } ``` This configures the gateway to allow any port withing `8000` `...` `9000` boundary inclusively meaning `8000` ,`8050`, `9000` will all be allowed. # Precedence Ports defined in `ports` property takes precedence over `ranges`.

For +convenience, all of the top-level functions use a global state available +via the spew.Config global. + +It is also possible to create a ConfigState instance that provides methods +equivalent to the top-level functions. This allows concurrent configuration +options. See the ConfigState documentation for more details. + +The following configuration options are available: + * Indent + String to use for each indentation level for Dump functions. + It is a single space by default. A popular alternative is "\t". + + * MaxDepth + Maximum number of levels to descend into nested data structures. + There is no limit by default. + + * DisableMethods + Disables invocation of error and Stringer interface methods. + Method invocation is enabled by default. + + * DisablePointerMethods + Disables invocation of error and Stringer interface methods on types + which only accept pointer receivers from non-pointer variables. + Pointer method invocation is enabled by default. + + * DisablePointerAddresses + DisablePointerAddresses specifies whether to disable the printing of + pointer addresses. This is useful when diffing data structures in tests. + + * DisableCapacities + DisableCapacities specifies whether to disable the printing of + capacities for arrays, slices, maps and channels. This is useful when + diffing data structures in tests. + + * ContinueOnMethod + Enables recursion into types after invoking error and Stringer interface + methods.

This PR makes sure we can still cross-compile aarch64 (arm64) with CGO disabled.
