2020-02-25docs: Move qemu-option-trace.rst.inc to docs/Peter Maydell
The qemu-option-trace.rst.inc file contains a rST documentation fragment which describes trace options common to qemu-nbd and qemu-img. We put this file into interop/, but we'd like to move the qemu-nbd and qemu-img files into the tools/ manual. We could move the .rst.inc file along with them, but we're eventually going to want to use it for the main QEMU binary options documentation too, and that will be in system/. So move qemu-option-trace.rst.inc to the top-level docs/ directory, where all these files can include it via .. include:: ../qemu-option-trace.rst.inc This does have the slight downside that we now need to explicitly tell Make which manuals use this file rather than relying on a wildcard for all .rst.inc in the manual.

2020-02-25docs: Create new 'tools' manualPeter Maydell
Some of the documentation for QEMU "tools" which are standalone binaries like qemu-img is an awkward fit in our current 5-manual split. We've put it into "interop", but they're not really about interoperability. Create a new top level manual "tools" which will be a better home for this documentation. This commit creates an empty initial manual; we will move the relevant documentation files in a subsequent commit.

The documentation of the various options and commands is rather muddled, with some options being described inside the relevant command description and some in a more general section near the start of the manual. All the command synopses are replicated in the .hx file and then again in the manual. A lot of text is also duplicated in the qemu-img.c code for the help text. I have not attempted to deal with any of this, but have simply transposed the existing structure into rST. As usual, there are some minor formatting changes but no textual changes, except that as with one or two other conversions I have dropped the 'see also' section since it's not very informative and looks odd in the HTML.

2020-02-03Makefile: Ensure we don't run Sphinx in parallel for manpagesPeter Maydell
Sphinx will corrupt its doctree cache if we run two copies of it in parallel. In commit 6bda415c10d966c8d3 we worked around this by having separate doctrees for 'html' vs 'manpage' runs. However now that we have more than one manpage produced from a single manual we can run into this again when trying to produce the two manpages. Use the trick described in 'Atomic Rules in GNU Make' https://www.cmcrossroads.com/article/atomic-rules-gnu-make to ensure that we only run the Sphinx manpage builder once for each manual, even if we're producing several manpages. This fixes doctree corruption in parallel builds and also avoids pointlessly running Sphinx more often than we need to. (In GNU Make 4.3 there is builtin support for this, via the "&:" syntax, but we can't wait for that to be available in all the distros we support...) The generic "one invocation for multiple output files" machinery is provided as a macro named 'atomic' in rules.mak; we then wrap this in a more specific macro for defining the rule and dependencies for the manpages in a Sphinx manual, to avoid excessive repetition.

2020-01-24build-sys: clean up flags included in the linker command linePaolo Bonzini
Some of the CFLAGS that are discovered during configure, for example compiler warnings, are being included on the linker command line because QEMU_CFLAGS is added to it. Other flags, such as the -m32, appear twice because they are included in both QEMU_CFLAGS and LDFLAGS. All this leads to confusion with respect to what goes in which Makefile variables (and we have plenty). So, introduce QEMU_LDFLAGS for flags discovered by configure, following the lead of QEMU_CFLAGS, and stop adding to it: 1) options that are already in CFLAGS, for example "-g" 2) duplicate options At the same time, options that _are_ needed by both compiler and linker must now be added to both QEMU_CFLAGS and QEMU_LDFLAGS, which is clearer. This is mostly -fsanitize options. For now, --extra-cflags has this behavior (but --extra-cxxflags does not). Meson will not include CFLAGS on the linker command line, do the same in our build system as well.

2020-01-23qemu-block-drivers: Convert to rSTPeter Maydell
The qemu-block-drivers documentation is currently in docs/qemu-block-drivers.texi in Texinfo format, which we present to the user as: * a qemu-block-drivers manpage * a section of the main qemu-doc HTML documentation Convert the documentation to rST format, and present it to the user as: * a qemu-block-drivers manpage * part of the system/ Sphinx manual This follows the same pattern we've done for qemu-ga and qemu-nbd. We have to drop a cross-reference from the documentation of the -cdrom option back to the qemu-block-drivers documentation, since they're no longer within the same texinfo document. As noted in a comment, the manpage output is slightly compromised due to limitations in Sphinx. In an ideal world, the HTML output would have the various headings like 'Disk image file formats' as top-level section headings (which then appear in the overall system manual's table-of-contents), and it would not have the section headings which make sense only for the manpage like 'synopsis', 'description', and 'see also'. Unfortunately, the mechanism Sphinx provides for restricting pieces of documentation is limited to the point of being flawed: the 'only::' directive is implemented as a filter that is applied at a very late stage in the document processing pipeline, rather than as an early equivalent of an #ifdef. This means that Sphinx's process of identifying which section heading markup styles are which levels of heading gets confused if the 'only::' directive contains section headings which would affect the heading-level of a later heading. I have opted to prioritise making the HTML format look better, with the compromise being that in the manpage the 'Disk image file formats' &c headings are top-level headings rather than being sub-headings under the traditional 'Description' top-level section title.

All the content of the old manpage is retained, except that I have dropped the "This is free software; see the source for copying conditions. There is NO warranty..." text that was in the old AUTHOR section; Sphinx's manpage builder doesn't expect that much text in the AUTHOR section, and since none of our other manpages have it it seems easiest to delete it rather than try to figure out where else in the manpage to put it. The only other textual change is that I have had to give the --nocache option its own description ("Equivalent to --cache=none") because Sphinx doesn't have an equivalent of using item/itemx to share a description between two options. Some minor aspects of the formatting have changed, to suit what is easiest for Sphinx to output. (The most notable is that Sphinx option section option syntax doesn't support '--option foo=bar' with bar underlined rather than bold, so we have to switch to '--option foo=BAR' instead.) The contents of qemu-option-trace.texi are now duplicated in docs/interop/qemu-option-trace.rst.inc, until such time as we complete the conversion of the other files which use it; since it has had only 3 changes in 3 years, this shouldn't be too awkward a burden. (We use .rst.inc because if this file fragment has a .rst extension then Sphinx complains about not seeing it in a toctree.)

The QAPI code generator clocks in at some 3100 SLOC in 8 source files. Almost 60% of the code is in qapi/common.py. Split it into more focused modules: * Move QAPISchemaPragma and QAPISourceInfo to qapi/source.py. * Move QAPIError and its sub-classes to qapi/error.py. * Move QAPISchemaParser and QAPIDoc to parser.py. Use the opportunity to put QAPISchemaParser first. * Move check_expr() & friends to qapi/expr.py. Use the opportunity to put the code into a more sensible order. * Move QAPISchema & friends to qapi/schema.py * Move QAPIGen and its sub-classes, ifcontext, QAPISchemaModularCVisitor, and QAPISchemaModularCVisitor to qapi/gen.py * Delete camel_case(), it's unused since commit e98859a9b9 "qapi: Clean up after recent conversions to QAPISchemaVisitor" A number of helper functions remain in qapi/common.py. I considered moving the code generator helpers to qapi/gen.py, but decided not to. Perhaps we should rewrite them as methods of QAPIGen some day.

2019-10-17sphinx: Use separate doctree directories for different buildersEduardo Habkost
sphinx-build is buggy when multiple processes are using the same doctree directory in parallel. See the 3-year-old Sphinx bug report at: https://github.com/sphinx-doc/sphinx/issues/2946 Instead of avoiding parallel builds or adding some kind of locking, I'm using the simplest solution: just using a different doctree cache for each builder.

2019-09-20Makefile: Fix in-tree builds when Sphinx is availablePeter Maydell
In commit 27a296fce9821e we switched the qemu-ga manpage over to being built from Sphinx. The makefile rules for this were correct for an out-of-tree build, but break for in-tree builds if Sphinx is present and we're trying to build the documentation. Specifically, because Sphinx refuses to build output files into the same directory as its sources, for an in-tree build we tell it to build into a subdirectory docs/built, and set up a makefile variable MANUAL_BUILDDIR indicating where the docs are going. The makefile rule telling Make how to build qemu-ga.8 correctly used this variable, but the lines adding qemu-ga.8 to the list of DOCS to be built and the 'make install' rune did not. The effect was that for an in-tree build we told Make to build 'docs/interop/qemu-ga.8' but did not provide a specific rule for doing so, which caused Make to fall back to the old rules.make rule for building any "%.8" file. Make tried to invoke texi2pod with a bogus command line, resulting in the error: GEN docs/interop/qemu-ga.8 No filename or title make: *** [rules.mak:394: docs/interop/qemu-ga.8] Fix this by using $(MANUAL_BUILDDIR) when constructing the list of DOCS files we want to build and also in the source file name we install for 'make install'. (Among other things, this broke the Shippable CI builds.)

2019-09-10tests/tcg: move configuration to a sub-shell scriptPaolo Bonzini
Avoid the repeated inclusions of config-target.mak, which have risks of namespace pollution, and instead build minimal configuration files in a configuration script. The same configuration files can also be included in Makefile and Makefile.qemu [AJB 10/09/19] In the original PR this had inadvertently enabled tests for ppc64abi32. However as the rest of the multiarch tests work rather than disabling the otherwise correctly functioning build I've just skipped the failing linux-test test. For some reason I can't debug it with TCG so I'm leaving that to the PPC maintainers to look at.
