12 daysscripts/checkpatch: reject license boilerplate on new filesDaniel P. Berrangé1-0/+23
The previous commit mandates use of SPDX-License-Identifier on common source files, and encourages it on all other files. Some contributors are none the less still also including the license boilerplate text. This is redundant and will potentially cause trouble if inconsistent with the SPDX declaration. Match common boilerplate text blurbs and report them as invalid, for newly added files.

12 daysscripts/checkpatch: reimplement mandate for SPDX-License-IdentifierDaniel P. Berrangé1-0/+15
Going forward we want all newly created source files to have an SPDX-License-Identifier tag present. Initially mandate this for C, Python, Perl, Shell source files, as well as JSON (QAPI) and Makefiles, while encouraging users to consider it for other file types. The new attempt at detecting missing SPDX-License-Identifier relies on the hooks for relying triggering logic at the end of scanning a new file in the diff.

When seeing a new/deleted/renamed file we check to see if MAINTAINERS is updated, but we don't give the user a list of files affected, as we don't want to repeat the same warning many times over.

12 daysscripts/checkpatch: introduce tracking of file start/endDaniel P. Berrangé1-3/+107
Some checks want to be performed either at the start of a new file within a patch, or at the end. This is complicated by the fact that the information relevant to the check may be spread across multiple lines. It is further complicated by a need to support both git and non-git diffs, and special handling for renames where there might not be any patch hunks. To handle this more sanely, introduce explicit tracking of file start/end, taking account of git metadata, and calling a hook function at each transition.

This reverts commit fa4d79c64dae03ffa269e42e21822453856618b7. The logic in this commit was flawed in two critical ways * It always failed to report SPDX validation on the last newly added file. IOW, it only worked if at least 2 new files were added in a commit * If an existing file change, followed a new file change, in the commit and the existing file context/changed lines included SPDX-License-Identifier, it would incorrectly associate this with the previous newly added file. Simply reverting this commit will make it significantly easier to understand the improved logic in the following commit.

2025-04-30meson/configure: add 'valgrind' option & --{en, dis}able-valgrind flagDaniel P. Berrangé1-0/+3
Currently valgrind debugging support for coroutine stacks is enabled unconditionally when valgrind/valgrind.h is found. There is no way to disable valgrind support if valgrind.h is present in the build env. This is bad for distros, as an dependency far down the chain may cause valgrind.h to become installed, inadvertently enabling QEMU's valgrind debugging support. It also means if a distro wants valgrind support there is no way to mandate this. The solution is to add a 'valgrind' build feature to meson and thus configure script. Signed-off-by: Daniel P.

This is equivalent to using qemu-img to convert a file to qcow2 and then writing the result to stdout, with the difference that this tool does not need to create this temporary qcow2 file and therefore does not need any additional disk space. Implementing this directly in qemu-img is not really an option because it expects the output file to be seekable and it is also meant to be a generic tool that supports all combinations of file formats and image options. Instead, this tool can only produce qcow2 files with the basic options, without compression, encryption or other features. The input file is read twice. The first pass is used to determine which clusters contain non-zero data and that information is used to create the qcow2 header, refcount table and blocks, and L1 and L2 tables. After all that metadata is created then the second pass is used to write the guest data. By default qcow2-to-stdout.py expects the input to be a raw file, but if qemu-storage-daemon is available then it can also be used to read images in other formats. Alternatively the user can also run qemu-nbd or qemu-storage-daemon manually instead.

2025-03-11scripts/qapi/backend: Clean up create_backend()'s failure modeMarkus Armbruster1-15/+9
create_backend()'s caller catches QAPIError, and returns non-zero exit code on catch. The caller's caller passes the exit code to sys.exit(). create_backend() doesn't care: it reports errors to stderr and sys.exit()s. Change it to raise QAPIError instead.

2025-03-11qapi/parser: add undocumented stub members to all_sectionsJohn Snow1-1/+16
Parser and doc generator cooperate on generating stub documentation for undocumented members. The parser makes up an ArgSection with an empty description, and the doc generator makes up a description. Right now, the made-up ArgSections go into doc.args. However, the new doc generator uses .all_sections, not .args. So put them into .all_sections, too. Insert them right after existing 'member' sections. If there are none, insert directly after the leading section. Doesn't affect the old generator, because that one doesn't use .all_sections.

2025-03-11qapi/source: allow multi-line QAPISourceInfo advancingJohn Snow1-2/+2
This is for the sake of the new rST generator (the "transmogrifier") so we can advance multiple lines on occasion while keeping the generated<-->source mappings accurate. next_line now simply takes an optional n parameter which chooses the number of lines to advance. The next patch will use this when converting section syntax in free-form documentation to more traditional rST section header syntax, which does not always line up 1:1 for line counts. For example: ``` ## # = Section <-- Info is pointing here, "L1" # # Lorem Ipsum ## ``` would be transformed to rST as: ``` ======= <-- L1 Section <-- L1 ======= <-- L1 <-- L2 Lorem Ipsum <-- L3 ``` After consuming the single "Section" line from the source, we want to advance the source pointer to the next non-empty line which requires jumping by more than one line.

2025-03-11qapi: clean up encoding of section kindsJohn Snow1-27/+70
We have several kinds of sections, and to tell them apart, we use Section attribute @tag and also the section object's Python type: type @tag untagged Section None @foo: ArgSection 'foo' Returns: Section 'Returns' Errors: Section 'Errors' Since: Section 'Since' TODO: Section 'TODO' Note: * @foo can be a member or a feature description, depending on context. * tag == 'Since' can be a Since: section or a member or feature description. If it's a Section, it's the former, and if it's an ArgSection, it's the latter. Clean this up as follows. Move the member or feature name to new ArgSection attribute @name, and replace @tag by enum @kind like this: type kind name untagged Section PLAIN @foo: ArgSection MEMBER 'foo' if member or argument ArgSection FEATURE 'foo' if feature Returns: Section RETURNS Errors: Section ERRORS Since: Section SINCE TODO: Section TODO The qapi-schema tests are updated to account for the new section names; "TODO" becomes "Todo" and `None` becomes "Plain" there.

2025-03-11qapi/parser: adjust info location for doc body sectionJohn Snow1-1/+5
Instead of using the info object for the doc block as a whole (which always points to the very first line of the block), update the info pointer for each call to ensure_untagged_section when the existing section is otherwise empty. This way, Sphinx error information will match precisely to where the text actually starts. For example, this patch will move the info pointer for the "Hello!" untagged section ... > ## <-- from here ... > # Hello! <-- ... to here. > ## This doesn't seem to improve error reporting now. It will with the forthcoming QAPI doc transmogrifier. If I stick bad rST into qapi/block-core.json like this: > ## > # @SnapshotInfo: > # > +# rST syntax error: *ahh! > +# > # @id: unique shapshot id > # > # @name: user chosen name The existing code's error message will point to the beginning of the doc comment, which is less than helpful. The transmogrifier's message will point to the erroneous line, but to accomplish this, it needs this patch.

This option is supported by both gcc (since 4.7) and clang (since 7.0). Not only does this make the linkers job easier by reducing the amount of ELF it needs to parse it also reduces the total build size quite considerably. In my case a default build went from 5.8G to 3.9G (vs 1.9G for --disable-debug-info). The --disable-split-debug option allows distros to keep all the info together for ease of packaging.

2025-03-04qapi: pluggable backend code generatorsDaniel P. Berrangé2-35/+108
The 'qapi.backend.QAPIBackend' class defines an API contract for code generators. The current generator is put into a new class 'qapi.backend.QAPICBackend' and made to be the default impl. A custom generator can be requested using the '-k' arg which takes a fully qualified python class name qapi-gen.py -B the.python.module.QAPIMyBackend This allows out of tree code to use the QAPI generator infrastructure to create new language bindings for QAPI schemas. This has the caveat that the QAPI generator APIs are not guaranteed stable, so consumers of this feature may have to update their code to be compatible with future QEMU releases.

Until now, the script has worked under the assumption that a host CPU can run binaries targeting any CPU in the same family. That's a fair enough assumption when it comes to running i386 binaries on x86_64, but it doesn't quite apply in the general case. For example, while riscv64 CPUs could theoretically run riscv32 applications natively, in practice there exist few (if any?) CPUs that implement the necessary silicon; moreover, even if you had one such CPU, your host OS would most likely not have enabled the necessary kernel bits. This new option gives distro packagers the ability to opt out of the assumption, likely on a per-architecture basis, and make things work out of the box for a larger fraction of their user base. As an interesting side effect, this makes it possible to enable execution of 64-bit binaries on 32-bit CPUs of the same family, which is a perfectly valid use case that apparently hadn't been considered until now.
