## Remote Execution Caching Compiler (RECC) Engineering CppCon 2024 September 19, 2024 Shivam Bairoliya Software Engineer TechAtBloomberg.com © 2024 Bloomberg Finance L.P. All rights reserved. ## ## What is RECC? • Remote Execution Caching Compiler (RECC) Open source build tool that wraps compiler commands and optionally forwards them to a remote build execution service Encompasses the capabilities remote linking and caching ## • Designed to share caches across diverse toolchains Works with many compiler toolchains (GCC, Clang, Solaris CC) o Supports multiple operating systems (Linux, macOS, Solaris)

When invoking the compiler, it needs to be able to resolve the location of #included files Typically: • Some default locations: ☐ Relative to the .cpp file (for “”) ☐ System or compiler installation locations hello_world.cpp.o -c hello_world.cpp -I/path/to/fmt/include The compiler needs to locate and load the binary module interface (BMI): |compiler|CLI| |---|---| |msvc|/reference fmt=/path/to/fmt.ifc| |clan foxtrot.o golf.o #include Compiler invocations: Embarrassingly parallel If many .cxx files in the project include the same headers - Each compiler invocation is parsing them independently

Fortunately, modern language design and compiler techniques make it possible to mostly eliminate the performance trade-off and provide a single environment computing, with performance comparable to traditional statically-typed languages. Because Julia's compiler is different from the interpreters used for languages like Python or R, you may find that Julia's

up anymore. Added in version 1.2.0. Warning: The default value is set to False for backwards compatibility. In future versions of Waitress this default will be changed to True. Warnings will be raised https://github.com/Pylons/waitress/issues/152, and https://github.com/Pylons/waitress/pull/202 ### 20.3 Compatibility • Waitress has now "vendored" asyncore into itself as waitress.wasyncore. This is to multisegment imports in some Python 2 revisions (see https://github.com/Pylons/waitress/pull/34). • For compatibility, WSGIServer is now an alias of TcpWSGIServer. The signature of BaseWSGIServer is now compatible

The The latter are special types which are not expressible in Kotlin and are used by the compiler in type inference, smart casts, etc. #### 2.1.1 Built-in types Kotlin type system uses the following

Python 3.5. Use a compatible object on earlier versions. Look at SWITCHING_PROTOCOLS in websockets.compatibility for an example.) This method may be overridden to check the request headers and set a different WebSocketURI into four variables, adjust your code to account for that fifth field. ## Also: • Added compatibility with Python 3.7. • connect() performs HTTP Basic Auth when the URI contains credentials. • Iterating connect()’s class argument to create_protocol to reflect that it can also be a callable. For backwards compatibility, klass is still supported. • serve() can be used as an asynchronous context manager on Python

Software version requirements and release notes This document refers to version 3.8.0. Django/Python compatibility table LTS in the table indicates a combination of Django and django CMS both covered by a long-term executed, the historical models may be out of sync with the applied database schema. To keep compatibility with 3.0 and 3.x you can force the data migration to run before the django CMS migration that the critical areas of the code explaining the behaviour appropriate test coverage Python 2/3 compatibility South and Django migrations (where applicable) The pull request description must briefly describe

=AsyncHTTPClient() response = await http_client.fetch(url) return response.body Or for compatibility with older versions of Python, using the tornado.gen module: from tornado.httpclient importAsyncHTTPClient and await keywords (functions using these keywords are also called “native coroutines”). For compatibility with older versions of Python, you can use “decorated” or “yield-based” coroutines using the tornado Native coroutines are the recommended form whenever possible. Only use decorated coroutines when compatibility with older versions of Python is required. Examples in the Tornado documentation will generally
