Run the following commands from your application's root directory: - -```bash -$ mkdir build -$ cd build -$ cmake .. -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=~/lambda-install -$ make -$ make aws-lambda-package-demo -``` -The last command above `make aws-lambda-package-demo` will create a zip file called `demo.zip` in the current directory. - -Now, create an IAM role and the Lambda function via the AWS CLI. - -First create the following trust policy JSON file - -``` -$ cat trust-policy.json -{ - "Version": "2012-10-17", - "Statement": [ - { - "Effect": "Allow", - "Principal": { - "Service": ["lambda.amazonaws.com"] - }, - "Action": "sts:AssumeRole" - } - ] -} - -``` -Then create the IAM role: - -```bash -$ aws iam create-role --role-name lambda-demo --assume-role-policy-document file://trust-policy.json -``` - -Note down the role Arn returned to you after running that command. We'll need it in the next steps: - -Attach the following policy to allow Lambda to write logs in CloudWatch: -```bash -$ aws iam attach-role-policy --role-name lambda-demo --policy-arn arn:aws:iam::aws:policy/service-role/AWSLambdaBasicExecutionRole -``` - -Make sure you attach the appropriate policies and/or permissions for any other AWS services that you plan on using. - -And finally, create the Lambda function: - -``` -$ aws lambda create-function --function-name demo \ ---role \ ---runtime provided --timeout 15 --memory-size 128 \ ---handler demo --zip-file fileb://demo.zip -``` - -And to invoke the function: -```bash -$ aws lambda invoke --function-name demo --payload '{"answer":42}' output.txt -``` - -## Using the C++ SDK for AWS with this runtime -This library is completely independent from the AWS C++ SDK. You should treat the AWS C++ SDK as just another dependency in your application. -See [the examples section](https://github.com/awslabs/aws-lambda-cpp/tree/master/examples/) for a demo utilizing the AWS C++ SDK with this Lambda runtime. - -## Supported Compilers -Any *fully* compliant C++11 compiler targeting GNU/Linux x86-64 should work. Please avoid compiler versions that provide half-baked C++11 support. - -- Use GCC v5.x or above -- Use Clang v3.3 or above - -## Packaging, ABI, GNU C Library, Oh My! -Lambda runs your code on some version of Amazon Linux. It would be a less than ideal customer experience if you are forced to build your application on that platform and that platform only. - -However, the freedom to build on any linux distro brings a challenge. The GNU C Library ABI. There is no guarantee the platform used to build the Lambda function has the same GLIBC version as the one used by AWS Lambda. In fact, you might not even be using GNU's implementation. For example you could build a C++ Lambda function using musl libc. - -To ensure that your application will run correctly on Lambda, we must package the entire C runtime library with your function. -If you choose to build on the same [Amazon Linux version used by lambda](https://docs.aws.amazon.com/lambda/latest/dg/current-supported-versions.html), you can avoid packaging the C runtime in your zip file. -This can be done by passing the `NO_LIBC` flag in CMake as follows: - -```cmake -aws_lambda_package_target(${PROJECT_NAME} NO_LIBC) -``` -### Common Pitfalls with Packaging - -* Any library dependency your Lambda function has that is dynamically loaded via `dlopen` will NOT be automatically packaged. You **must** add those dependencies manually to the zip file. -This applies to any configuration or resource files that your code depends on. - -* If you are making HTTP calls over TLS (https), keep in mind that the CA bundle location is different between distros. -For example, if you are using the AWS C++ SDK, it's best to set the following configuration options: - -```cpp -Aws::Client::ClientConfiguration config; -config.caFile = "/etc/pki/tls/certs/ca-bundle.crt"; -``` -If you are not using the AWS C++ SDK, but happen to be using libcurl directly, you can set the CA bundle location by doing: -```c -curl_easy_setopt(curl_handle, CURLOPT_CAINFO, "/etc/pki/tls/certs/ca-bundle.crt"); -``` - -## FAQ & Troubleshooting -1. **Why is the zip file so large? what are all those files?** - Typically, the zip file is large because we have to package the entire C standard library. - You can reduce the size by doing some or all of the following: - - Ensure you're building in release mode `-DCMAKE_BUILD_TYPE=Release` - - If possible, build your function using musl libc, it's tiny. The easiest way to do this, assuming your code is portable, is to build on Alpine linux, which uses musl libc by default. -1. **How to upload a zip file that's bigger than 50MB via the CLI?** - Upload your zip file to S3 first: - ```bash - $ aws s3 cp demo.zip s3://mys3bucket/demo.zip - ``` - NOTE: you must use the same region for your S3 bucket as the lambda. - - Then you can create the Lambda function this way: - - ```bash - $ aws lambda create-function --function-name demo \ - --role \ - --runtime provided --timeout 15 --memory-size 128 \ - --handler demo - --code "S3Bucket=mys3bucket,S3Key=demo.zip" - ``` -1. **My code is crashing, how can I debug it?** - - - Starting with [v0.2.0](https://github.com/awslabs/aws-lambda-cpp/releases/tag/v0.2.0) you should see a stack-trace of the crash site in the logs (which are typically stored in CloudWatch). - - To get a more detailed stack-trace with source-code information such as line numbers, file names, etc. you need to install one of the following packages: - - On Debian-based systems - `sudo apt install libdw-dev` or `sudo apt install binutils-dev` - - On RHEL based systems - `sudo yum install elfutils-devel` or `sudo yum install binutils-devel` - If you have either of those packages installed, CMake will detect them and automatically link to them.

T can be any -// copyable type. If it's a raw pointer, you are responsible for managing the -// lifespan of the pointed values. - -class FooTest : public ::testing::TestWithParam { - // You can implement all the usual class fixture members here. -}; - -// Then, use the TEST_P macro to define as many parameterized tests -// for this fixture as you want. The _P suffix is for "parameterized" -// or "pattern", whichever you prefer to think. - -TEST_P(FooTest, DoesBlah) { - // Inside a test, access the test parameter with the GetParam() method - // of the TestWithParam class: - EXPECT_TRUE(foo.Blah(GetParam())); - ... -} - -TEST_P(FooTest, HasBlahBlah) { - ... -} - -// Finally, you can use INSTANTIATE_TEST_SUITE_P to instantiate the test -// case with any set of parameters you want. Google Test defines a number -// of functions for generating test parameters. They return what we call -// (surprise!) parameter generators. Here is a summary of them, which -// are all in the testing namespace: -// -// -// Range(begin, end [, step]) - Yields values {begin, begin+step, -// begin+step+step, ...}. The values do not -// include end. step defaults to 1. -// Values(v1, v2, ..., vN) - Yields values {v1, v2, ..., vN}. -// ValuesIn(container) - Yields values from a C-style array, an STL -// ValuesIn(begin,end) container, or an iterator range [begin, end). -// Bool() - Yields sequence {false, true}. -// Combine(g1, g2, ..., gN) - Yields all combinations (the Cartesian product -// for the math savvy) of the values generated -// by the N generators. -// -// For more details, see comments at the definitions of these functions below -// in this file. -// -// The following statement will instantiate tests from the FooTest test suite -// each with parameter values "meeny", "miny", and "moe". - -INSTANTIATE_TEST_SUITE_P(InstantiationName, - FooTest, - Values("meeny", "miny", "moe")); - -// To distinguish different instances of the pattern, (yes, you -// can instantiate it more than once) the first argument to the -// INSTANTIATE_TEST_SUITE_P macro is a prefix that will be added to the -// actual test suite name. Remember to pick unique prefixes for different -// instantiations. The tests from the instantiation above will have -// these names: -// -// * InstantiationName/FooTest.DoesBlah/0 for "meeny" -// * InstantiationName/FooTest.DoesBlah/1 for "miny" -// * InstantiationName/FooTest.DoesBlah/2 for "moe" -// * InstantiationName/FooTest.HasBlahBlah/0 for "meeny" -// * InstantiationName/FooTest.HasBlahBlah/1 for "miny" -// * InstantiationName/FooTest.HasBlahBlah/2 for "moe" -// -// You can use these names in --gtest_filter. -// -// This statement will instantiate all tests from FooTest again, each -// with parameter values "cat" and "dog": - -const char* pets[] = {"cat", "dog"}; -INSTANTIATE_TEST_SUITE_P(AnotherInstantiationName, FooTest, ValuesIn(pets)); - -// The tests from the instantiation above will have these names: -// -// * AnotherInstantiationName/FooTest.DoesBlah/0 for "cat" -// * AnotherInstantiationName/FooTest.DoesBlah/1 for "dog" -// * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat" -// * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog" -// -// Please note that INSTANTIATE_TEST_SUITE_P will instantiate all tests -// in the given test suite, whether their definitions come before or -// AFTER the INSTANTIATE_TEST_SUITE_P statement. -// -// Please also note that generator expressions (including parameters to the -// generators) are evaluated in InitGoogleTest(), after main() has started. -// This allows the user on one hand, to adjust generator parameters in order -// to dynamically determine a set of tests to run and on the other hand, -// give the user a chance to inspect the generated tests with Google Test -// reflection API before RUN_ALL_TESTS() is executed. -// -// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc -// for more examples. -// -// In the future, we plan to publish the API for defining new parameter -// generators. But for now this interface remains part of the internal -// implementation and is subject to change. -// -// -// A parameterized test fixture must be derived from testing::Test and from -// testing::WithParamInterface, where T is the type of the parameter -// values. Inheriting from TestWithParam satisfies that requirement because -// TestWithParam inherits from both Test and WithParamInterface. In more -// complicated hierarchies, however, it is occasionally useful to inherit -// separately from Test and WithParamInterface. For example: - -class BaseTest : public ::testing::Test { - // You can inherit all the usual members for a non-parameterized test - // fixture here. -}; - -class DerivedTest : public BaseTest, public ::testing::WithParamInterface { - // The usual test fixture members go here too. -}; - -TEST_F(BaseTest, HasFoo) { - // This is an ordinary non-parameterized test. -} - -TEST_P(DerivedTest, DoesBlah) { - // GetParam works just the same here as if you inherit from TestWithParam. - EXPECT_TRUE(foo.Blah(GetParam())); -} - -#endif // 0 - -#include - -// Copyright 2008 Google Inc. -// All Rights Reserved. -// -// Redistribution and use in source and binary forms, with or without -// modification, are permitted provided that the following conditions are -// met: -// -// * Redistributions of source code must retain the above copyright -// notice, this list of conditions and the following disclaimer. -// * Redistributions in binary form must reproduce the above -// copyright notice, this list of conditions and the following disclaimer -// in the documentation and/or other materials provided with the -// distribution. -// * Neither the name of Google Inc. nor the names of its -// contributors may be used to endorse or promote products derived from -// this software without specific prior written permission. -// -// THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS -// "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT -// LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR -// A PARTICULAR PURPOSE ARE DISCLAIMED.
