a130bbd154d535b80fe9f602a13bf2e322817881 Squashed 'src/leveldb/' changes from 04b5790928..4188247086 (fanquake)

Pull request description:

  Cherry-picks two commits from upstream (302786e211, e829478c6a), which remove the usage of `std::aligned_storage/std::aligned_union`.

  Note the first cherry-pick is not clean, because due to Google tooling issues, it accidently contained a revert of the prior two commits. See https://github.com/google/leveldb/pull/1249 for more details.

  Also see https://issues.chromium.org/issues/388068052, although note that they [reverted the roll to latest leveldb](https://issues.chromium.org/issues/388068052#comment9). I'm guessing due to the acidental reversion issue above.

CI Scripts

This directory contains scripts for each build step in each build stage.

Running a Stage Locally

Be aware that the tests will be built and run in-place, so please run at your own risk. If the repository is not a fresh git clone, you might have to clean files from previous builds or test runs first.

The ci needs to perform various sysadmin tasks such as installing packages or writing to the user's home directory. While it should be fine to run the ci system locally on your development box, the ci scripts can generally be assumed to have received less review and testing compared to other parts of the codebase. If you want to keep the work tree clean, you might want to run the ci system in a virtual machine with a Linux operating system of your choice.

To allow for a wide range of tested environments, but also ensure reproducibility to some extent, the test stage requires bash, docker, and python3 to be installed. To run on different architectures than the host qemu is also required. To install all requirements on Ubuntu, run

sudo apt install bash docker.io python3 qemu-user-static

It is recommended to run the ci system in a clean env. To run the test stage with a specific configuration,

env -i HOME="$HOME" PATH="$PATH" USER="$USER" bash -c 'FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh'

Configurations

The test files (FILE_ENV) are constructed to test a wide range of configurations, rather than a single pass/fail. This helps to catch build failures and logic errors that present on platforms other than the ones the author has tested.

Some builders use the dependency-generator in ./depends, rather than using the system package manager to install build dependencies. This guarantees that the tester is using the same versions as the release builds, which also use ./depends.

It is also possible to force a specific configuration without modifying the file. For example,

env -i HOME="$HOME" PATH="$PATH" USER="$USER" bash -c 'MAKEJOBS="-j1" FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh'

The files starting with 0n (n greater than 0) are the scripts that are run in order.

Cache

In order to avoid rebuilding all dependencies for each build, the binaries are cached and reused when possible. Changes in the dependency-generator will trigger cache-invalidation and rebuilds as necessary.
