| | | | | | | | | | | | | Change documentation style and fix minor typos in tests/qtest/libqos/qgraph.h to automatically generate sphinx documentation in docs/devel/qgraph.rst The mechanism explanation that once was in qgraph.h is now moved to qgraph.rst There is no functional change intended.

* docs: move CODING_STYLE into the developer documentationAlex Bennée2021-02-241-0/+1
| | | | | | | | | | | There is no particular reason to keep this on it's own in the root of the tree. Move it into the rest of the fine developer manual and fixup any links to it. The only tweak I've made is to fix the code-block annotations to mention the language C.

* scripts: add block-coroutine-wrapper.pyVladimir Sementsov-Ogievskiy2020-10-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a very frequent pattern of creating a coroutine from a function with several arguments: - create a structure to pack parameters - create _entry function to call original function taking parameters from struct - do different magic to handle completion: set ret to NOT_DONE or EINPROGRESS or use separate bool field - fill the struct and create coroutine from _entry function with this struct as a parameter - do coroutine enter and BDRV_POLL_WHILE loop Let's reduce code duplication by generating coroutine wrappers. This patch adds scripts/block-coroutine-wrapper.py together with some friends, which will generate functions with declared prototypes marked by the 'generated_co_wrapper' specifier. The usage of new code generation is as follows: 1. define the coroutine function somewhere int coroutine_fn bdrv_co_NAME(...) {...} 2. declare in some header file int generated_co_wrapper bdrv_NAME(...); with same list of parameters (generated_co_wrapper is defined in "include/block/block.h"). 3. Make sure the block_gen_c declaration in block/meson.build mentions the file with your marker function. Still, no function is now marked, this work is for the following commit.

* docs: add Secure Coding Practices to developer docsStefan Hajnoczi2019-05-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | At KVM Forum 2018 I gave a presentation on security in QEMU: https://www.youtube.com/watch?v=YAdRf_hwxU8 (video) https://vmsplice.net/~stefan/stefanha-kvm-forum-2018.pdf (slides) This patch adds a guide to secure coding practices. This document covers things that developers should know about security in QEMU. It is just a starting point that we can expand on later. I hope it will be useful as a resource for new contributors and will save code reviewers from explaining the same concepts many times.

* docs: Provide separate conf.py for each manual we wantPeter Maydell2019-03-071-0/+21
By default Sphinx wants to build a single manual at once. For QEMU, this doesn't suit us, because we want to have separate manuals for "Developer's Guide", "User Manual", and so on, and we don't want to ship the Developer's Guide to end-users. However, we don't want to completely duplicate conf.py for each manual, and we'd like to continue to support "build all docs in one run" for third-party sites like readthedocs.org. Make the top-level conf.py support two usage forms: (1) as a common config file which is included by the conf.py for each of QEMU's manuals: in this case sphinx-build is run multiple times, once per subdirectory. (2) as a top level conf file which will result in building all the manuals into a single document: in this case sphinx-build is run once, on the top-level docs directory. Provide per-manual conf.py files and top level pages for our first two manuals: * QEMU Developer's Guide (docs/devel) * QEMU System Emulation Management and Interoperability Guide (docs/interop) Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Aleksandar Markovic <amarkovic@wavecomp.com> Message-id: 20190305172139.32662-9-peter.maydell@linaro.org Message-id: 20190228145624.24885-9-peter.maydell@linaro.org
