907b846653 qapi: Touch generated files only when they change
A massive number of objects depends on QAPI-generated headers.  In my
"build everything" tree, it's roughly 4800 out of 5100.  This is
particularly annoying when only some of the generated files change,
say for a doc fix.

Improve qapi-gen.py to touch its output files only if they actually
change.  Rebuild time for a QAPI doc fix drops from many minutes to a
few seconds.  Rebuilds get faster for certain code changes, too.  For
instance, adding a simple QMP event now recompiles less than 200
instead of 4800 objects.  But adding a QAPI type is as bad as ever;
we've clearly got more work to do.

fb0bc835e5 qapi-gen: New common driver for code and doc generators
Whenever qapi-schema.json changes, we run six programs eleven times to
update eleven files.  Similar for qga/qapi-schema.json.  This is
silly.  Replace the six programs by a single program that spits out
all eleven files.

The programs become modules in new Python package qapi, along with the
helper library.  This requires moving them to scripts/qapi/.  While
moving them, consistently drop executable mode bits.

26df4e7fab qapi: Turn generators into modules
The next commit will introduce a common driver program for all
generators.  The generators need to be modules for that.  qapi2texi.py
already is.  Make the other generators follow suit.

The changes are actually trivial.  Obvious in the diffs once you view

47a6ea9aab qapi: New classes QAPIGenC, QAPIGenH, QAPIGenDoc
These classes encapsulate accumulating and writing output.

Convert C code generation to QAPIGenC and QAPIGenH.  The conversion is
rather shallow: most of the output accumulation is not converted.
Left for later.

The indentation machinery uses a single global variable indent_level,
even though we generally interleave creation of a .c and its .h.  It
should become instance variable of QAPIGenC.  Also left for later.

Documentation generation isn't converted, and QAPIGenDoc isn't used.
This will change shortly.

fb1a66bc01 tracetool: Update argument format regex to non-greedy star
Using the greedy star matching, arguments like "...%"PRIx64 caused issues
for functions with multiple PRI formats.

The issue was only seen with the ust backend, as it is the only one
using the format regex.

The result for many functions was that the arguments coming after the
greedy star end was left out of the tracepoint, and in some cases some
of the arguments that was traced had the wrong format.

af99fa9fe2 qemu.py: better control of created files
To launch a VM, we need to create basically two files: the monitor
socket (if it's a UNIX socket) and the qemu log file.

For the qemu log file, we currently just open the path, which will
create the file if it does not exist or overwrite the file if it does
exist.

For the monitor socket, if it already exists, we are currently removing
it, even if it's not created by us.

This patch moves to _pre_launch() the responsibility to create a
temporary directory to host the files so we can remove the whole
directory on _post_shutdown().

f7a5376d4b qapi: ensure stable sort ordering when checking QAPI entities
Some early python 3.x versions will have different default
ordering when calling the 'values()' method on a dict, compared
to python 2.x and later 3.x versions. Explicitly sort the items
to get a stable ordering.

The iteritems()/itervalues() methods are gone in py3, but the
items()/values() methods are still around. The latter are less
efficient than the former in py2, but this has unmeasurably
small impact on QEMU build time, so taking portability over

Python 3 no longer supports the bare "print" statement, it must be
called as a normal function with round brackets. It is possible to
opt-in to this new syntax with Python 2.6 onwards by importing the
"print_function" from the "__future__" module, making it easy to
support Python 2 and 3 in parallel.

6f49ec4034 dump-guest-memory.py: fix python 2 support
Python GDB support may use Python 2 or 3.

Inferior.read_memory() may return a 'buffer' with Python 2 or a
'memoryview' with Python 3 (see also
https://sourceware.org/gdb/onlinedocs/gdb/Inferiors-In-Python.html)

The elf.add_vmcoreinfo_note() method expects a "bytes" object. Wrap
the returned memory with bytes(), which works with both 'memoryview'
and 'buffer'.

Fixes a regression introduced with commit
d23bfa91b7 ("add vmcoreinfo").

f4bdc13e49 checkpatch: Enforce proper do/while (0) style
Use of a loop construct for code that is not intended to repeat
does not make much idiomatic sense, except in one place: it is a
common usage in macros in order to wrap arbitrary code with
single-statement semantics.  But when used in a macro, it is more
typical for the caller to supply the trailing ';' when calling
the macro.

Although qemu coding style frowns on bare:
  if (cond)
    statement1;
  else
    statement2;
where extra semicolons actually cause syntax errors, we still
want our macro styles to be easily copied to other projects.
Thus, declare it an error if we encounter any form of 'while (0)'
with a semicolon in the same line.

2ced93eee0 linux-user: Separate binfmt arm CPU families
Give big-endian arm and aarch64 CPUs their own family in
qemu-binfmt-conf.sh to make sure we register qemu-user for binaries of
the opposite endianness on arm and aarch64. Apart from the family
assignments of the magic values, qemu_get_family() needs to be able to
distinguish the two and recognise aarch64{,_be} as well.

65255e8efd target/*helper: don't check retaddr before calling cpu_restore_state
cpu_restore_state officially supports being passed an address it can't
resolve the state for. As a result the checks in the helpers are
superfluous and can be removed. This makes the code consistent with
other users of cpu_restore_state.

Of course this does nothing to address what to do if cpu_restore_state
can't resolve the state but so far it seems this is handled elsewhere.

The change was made with included coccinelle script.

de6b4f908c qemu-options: Remove stray colons from output of --help
Commit 43f187a broke --help: it put colons into blank lines.  It
removed the colon from DEFHEADING(TITLE:) and added it back in the
macro expansion of DEFHEADING(TITLE), so hxtool can emit "@subsection
TITLE" more easily.  Trouble is it's added back even for the blank
lines made with DEFHEADING().

Put the colons back where they were before commit 43f187a, and strip
them in hxtool instead.

1b3bbc6887 Use qemu.org domain name
The owner of qemu.org has delegated authority to modify DNS records to
the QEMU Project.  This has allowed us to use the domain name without
worries about IP address changes or technical issues disrupting service.
The issues described in commit 8593898109
("Use qemu-project.org domain name") have therefore been mitigated.

This patch switches back to consistently using qemu.org instead of
qemu-project.org in documentation, version.rc, and the Windows installer
script.

The git submodules and SeaBIOS still use qemu-project.org for the time
being.  This will be fixed in the QEMU 2.12 release cycle.

d0dead3b6d scripts/make-release: ship u-boot source as a tarball
The u-boot sources we ship currently cause problems with unpacking on
a case-insensitive filesystem due to path conflicts. This has been
fixed in upstream u-boot via commit 610eec7f, but since it is not
yet included in an official release we implement this approach as a
temporary workaround.

Once we move to a u-boot containing commit 610eec7f we should revert
this patch.

49ad3cfa67 build: delay check for empty git submodule list
We short circuit the git submodule update when passed an empty module list.
This accidentally causes the 'status' command to write to the status file. The
test needs to be delayed into the individual commands to avoid this premature
writing of the status file.

37b5e74e28 build: don't fail if given a git submodule which does not exist
If going back in time in git history, across a commit that introduces a new
submodule, the 'git-submodule.sh' script will fail, causing rebuild to fail.

This is because config-host.mak contains a GIT_SUBMODULES variable that lists
a submodule that only exists in the later commit. config-host.mak won't get
repopulated until config.status is invoked, but make won't get this far due to
the submodule error.

This change makes 'git-submodule.sh' check whether each module is known to git
and drops any which are not present. A warning message will be printed when any
submodule is dropped in this manner.

f62bbee55d build: allow automatic git submodule updates to be disabled
Some people building QEMU use VPATH builds where the source directory is on a
read-only volume. In such a case 'scripts/git-submodules.sh update' will always
fail and users are required to run it manually themselves on their original
writable source directory.

While this is already supported, it is nice to give users a command line flag
to configure to permanently disable automatic submodule updates, as it means
they won't get hard to diagnose failures from git-submodules.sh at an arbitrary
later date.

This patch thus introduces a flag '--disable-git-update' which will prevent
'make' from ever running 'scripts/git-submodules.sh update'. It will still run
the 'status' command to determine if a submodule update is needed, but when it
does this it'll simply stop and print a message instructing the developer what
todo. eg

$ ./configure  --target-list=x86_64-softmmu --disable-git-update
...snip...

$ make
  GEN     config-host.h
  GEN     trace/generated-tcg-tracers.h
  GEN     trace/generated-helpers-wrappers.h
  GEN     trace/generated-helpers.h
  GEN     trace/generated-helpers.c
  GEN     module_block.h

The https://gitlab.com/keycodemap/keycodemapdb/ repo contains a
data file mapping between all the different scancode/keycode/keysym
sets that are known, and a tool to auto-generate lookup tables for
different combinations.

It is used by GTK-VNC, SPICE-GTK and libvirt for mapping keys.
Using it in QEMU will let us replace many hand written lookup
tables with auto-generated tables from a master data source,
reducing bugs. Adding new QKeyCodes will now only require the
master table to be updated, all ~20 other tables will be
automatically updated to follow.

47bb908dd1 docker: don't rely on submodules existing in the main checkout
When building the tarball to pass into the docker/vm test image,
the code relies on the git submodules being checked out in the
main checkout.

ie if the developer has not run 'git submodule update --init dtc'
many of the docker tests will fail due to the libfdt package not
being present in the test images. Patchew manually checks out the
dtc submodule in the main git checkout, but this is a bad idea.

When running tests we want to have a predictable set of submodules
included in the source that's tested. The build environment is
completely independent of the developers host OS, so the submodules
the developer has checked out should not be considered relevant for
the tests.

This changes the archive-source.sh script so that it clones the
current git checkout into a temporary directory, checks out a
fixed set of submodules, builds the tarball and finally removes
the temporary git clone.

aef45d51d1 build: automatically handle GIT submodule checkout for dtc
Currently if DTC is required by configure and not available in the host
OS install, we exit with an error message telling the user to checkout a
git submodule or install the library.

This introduces automatic handling of the git submodule checkout process
and enables it for dtc. This only runs if building from GIT, so users of
release tarballs still need the system library install. The current state
of the git checkout is stashed in .git-submodule-status, and a helper
program is used to determine if this state matches the desired submodule
state. A dependency against 'Makefile' ensures that the submodule state
is refreshed at the start of the build process

don't need debugging output, because debug messages don't trigger
the "No handlers could be found for logger" message from the
Python logging module.

Scripts that already configure logging but don't use debug=True
(e.g. scripts/vm/basevm.py) will get QMP debugging enabled for
free.

3d5eecab4a Add --firmwarepath to configure
Add a firmware path config option to configure.  Multiple directories
are accepted, with the usual colon as separator.  Default value is
${prefix}/share/qemu-firmware.  The path is searched in addition to the
current search path (typically ${prefix}/share/qemu).

This prepares qemu for the planned split of the prebuilt firmware blobs
into a separate project.

Distributions can also use this to get rid of the firmware symlink farm
and add -- for example -- /usr/share/seabios to the firmware path
instead.

5810314e98 qemu.py: Call logging.basicConfig() automatically
Not all scripts using qemu.py configure the Python logging
module, and end up generating a "No handlers could be found for
logger" message instead of actual log messages.

To avoid requiring every script using qemu.py to configure
logging manually, call basicConfig() when creating a QEMUMachine
object.  This won't affect scripts that already set up logging,
but will ensure that scripts that don't configure logging keep
working.

825bfa0052 checkpatch: add hwaddr to @typeList
The script doesn't know about all possible types and learn them as
it parses the code. If it reaches a line with a type cast but the
type isn't known yet, it is misinterpreted as an identifier.

For example the following line:

    foo = (hwaddr) -1;

results in the following false-positive to be reported:

ERROR: spaces required around that '-' (ctx:VxV)

Let's add this standard QEMU type to the list of pre-known types.

8e1fe1753a scripts: let checkpatch.pl process an entire GIT branch
Currently before submitting a series, devs should run checkpatch.pl
across each patch to be submitted. This can be automated using a
command such as:

  git rebase -i master -x 'git show | ./scripts/checkpatch.pl -'

This is rather long winded to type, so this patch introduces a way
to tell checkpatch.pl to validate a series of GIT revisions.

There are now three modes it can operate in 1) check a patch 2) check a source
file, or 3) check a git branch.

If no flags are given, the mode is determined by checking the args passed to
the command. If the args contain a literal ".." it is treated as a GIT revision
list. If the args end in ".patch" or equal "-" it is treated as a patch file.
Otherwise it is treated as a source file.

This automatic guessing can be overridden using --[no-]patch --[no-]file or
--[no-]branch

For example to check a GIT revision list:

    $ ./scripts/checkpatch.pl master..
    total: 0 errors, 0 warnings, 297 lines checked

    b886d352a2bf58f0996471fb3991a138373a2957 has no obvious style problems and is ready for submission.
    total: 0 errors, 0 warnings, 182 lines checked

    2a731f9a9ce145e0e0df6d42dd2a3ce4dfc543fa has no obvious style problems and is ready for submission.
    total: 0 errors, 0 warnings, 102 lines checked

    11844169bcc0c8ed4449eb3744a69877ed329dd7 has no obvious style problems and is ready for submission.

If a genuine patch filename contains the characters '..' it is
possible to force interpretation of the arg as a patch

  $ ./scripts/checkpatch.pl --patch master..

will force it to load a patch file called "master..", or equivalently

  $ ./scripts/checkpatch.pl --no-branch master..

will simply turn off guessing of GIT revision lists.

4738b0a85a qemu.py: avoid writing to stdout/stderr
This module should not write directly to stdout/stderr. Instead, it
should either raise exceptions or just log the messages and let the
callers handle them and decide what to do. For example, scripts could
choose to send the log messages stderr or/and write them to a file if
verbose or debugging mode is enabled.

This patch replaces the writes to stderr by an exception in the
send_fd_scm() when _socket_scm_helper is not set or not present. In the
same method, the subprocess Popen will now redirect the stdout/stderr to
logging.debug instead of writing to system stderr. As consequence, since
the Popen.communicate() is now used (in order to get the stdout), the
further call to wait() became redundant and was replaced by
Popen.returncode.

The shutdown() message on negative exit code will now be logged
to logging.warn instead of written to system stderr.

A future patch will generate enums with "holes".  NULL-termination
will cease to work then.

To prepare for that, store the length in the FOO_lookup by wrapping it
in a struct and adding a member for the length.

The sentinel will be dropped next.

fda72ab451 qapi: Fix error handling code on alternate conflict
The conflict check added by commit c0644771 ("qapi: Reject
alternates that can't work with keyval_parse()") doesn't work
with the following declaration:

  { 'alternate': 'Alt',
    'data': { 'one': 'bool',
              'two': 'str' } }

It crashes with:

  Traceback (most recent call last):
    File "./scripts/qapi-types.py", line 295, in <module>
      schema = QAPISchema(input_file)
    File "/home/ehabkost/rh/proj/virt/qemu/scripts/qapi.py", line 1468, in __init__
      self.exprs = check_exprs(parser.exprs)
    File "/home/ehabkost/rh/proj/virt/qemu/scripts/qapi.py", line 958, in check_exprs
      check_alternate(expr, info)
    File "/home/ehabkost/rh/proj/virt/qemu/scripts/qapi.py", line 830, in check_alternate
      % (name, key, types_seen[qtype]))
  KeyError: 'QTYPE_QSTRING'

This happens because the previously-seen conflicting member
('one') can't be found at types_seen[qtype], but at
types_seen['QTYPE_BOOL'].

Fix the bug by moving the error check to the same loop that adds
new items to types_seen, raising an exception if types_seen[qt]
is already set.

Add two additional test cases that can detect the bug.

47e1cb1f0a scripts: add argparse module for Python 2.6 compatibility
The minimum Python version supported by QEMU is 2.6.  The argparse
standard library module was only added in Python 2.7.  Many scripts
would like to use argparse because it supports command-line
sub-commands.

This patch adds argparse.  See the top of argparse.py for details.

840d835177 simpletrace: fix flight recorder --no-header option
The simpletrace.py script can pretty-print flight recorder ring buffers.
These are not full simpletrace binary trace files but just the end of a
trace file.  There is no header and the event ID mapping information is
often unavailable since the ring buffer may have filled up and discarded
event ID mapping records.

The simpletrace.stp script that generates ring buffer traces uses the
same trace-events-all input file as simpletrace.py.  Therefore both
scripts have the same global ordering of trace events.  A dynamic event
ID mapping isn't necessary: just use the trace-events-all file as the
reference for how event IDs are numbered.

It is now possible to analyze simpletrace.stp ring buffers again using:

  $ ./simpletrace.py trace-events-all path/to/ring-buffer

d6b76d6805 trace: use static event ID mapping in simpletrace.stp
This is a partial revert of commit
7f1b588f20 ("trace: emit name <-> ID
mapping in simpletrace header"), which broke the SystemTap flight
recorder because event mapping records may not be present in the ring
buffer when the trace is analyzed.  This means simpletrace.py
--no-header does not know the event ID mapping needed to pretty-print
the trace.

Instead of numbering events dynamically, use a static event ID mapping
as dictated by the event order in the trace-events-all file.

The simpletrace.py script also uses trace-events-all so the next patch
will fix the simpletrace.py --no-header option to take advantage of this
knowledge.

3932ef3ffb trace: add TRACE_<event>_BACKEND_DSTATE()
QEMU keeps track of trace event enabled/disabled state and provides
monitor commands to inspect and modify the "dstate".  SystemTap and
LTTng UST maintain independent enabled/disabled states for each trace
event, the other backends rely on QEMU dstate.

Introduce a new per-event macro that combines backend-specific dstate
like this:

  #define TRACE_MY_EVENT_BACKEND_DSTATE() ( \
      QEMU_MY_EVENT_ENABLED() || /* SystemTap */ \
      tracepoint_enabled(qemu, my_event) /* LTTng UST */ || \
      false)

This will be used to extend trace_event_get_state() in the next patch.

[Daniel Berrange pointed out that QEMU_MY_EVENT_ENABLED() must be true
by default, not false.  This way events will fire even if the DTrace
implementation does not implement the SystemTap semaphores feature.

Ubuntu Precise uses lttng-ust-dev 2.0.2 which does not have
tracepoint_enabled(), so we need a compatibility wrapper to keep Travis
builds passing.

ea1ff54f7d trace: ensure unique function / variable names per .stp file
The simpletrace compatibility code for systemtap creates a
function and some global variables for mapping to event ID
numbers. We generate multiple -simpletrace.stp files though,
one per target and systemtap considers functions & variables
to be globally scoped, not per file. So if trying to use the
simpletrace compat probes, systemtap will complain:

 # stap -e 'probe qemu.system.arm.simpletrace.visit_type_str { print( "hello")}'

086ee7a620 scripts: use build_ prefix for string not piped through cgen()
The gen_ prefix is awkward.  Generated C should go through cgen()
exactly once (see commit 1f9a7a1).  The common way to get this wrong is
passing a foo=gen_foo() keyword argument to mcgen().  I'd like us to
adopt a naming convention where gen_ means "something that's been piped
through cgen(), and thus must not be passed to cgen() or mcgen()".
Requires renaming gen_params(), gen_marshal_proto() and
gen_event_send_proto().

e8c2091d4c checkpatch: should not use signal except for SIG_DFL or SIG_IGN
Using signal to establish a signal handler is not portable; on
SysV systems, the signal handler would be reset to SIG_DFL after
delivery, while BSD preserves the signal handler.  Daniel Berrange
reported that (to complicate matters further) the signal system call
has SysV behavior, but glibc signal() actually calls the sigaction
system call to provide BSD behavior.

However, using signal() to set a signal's disposition to SIG_DFL
or SIG_IGN is portable and is a relatively common occurrence in
QEMU source code, so allow that.

23ea4f3032 scripts: Test script to look for -device crashes
Test code to check if we can crash QEMU using -device. It will
test all accel/machine/device combinations by default, which may
take a few hours (it's more than 90k test cases). There's a "-r"
option that makes it test a random sample of combinations.

The scripts contains a whitelist for: 1) known error messages
that make QEMU exit cleanly; 2) known QEMU crashes.

This is the behavior when the script finds a failure:

* Known clean (exitcode=1) errors generate DEBUG messages
  (hidden by default)
* Unknown clean (exitcode=1) errors will generate INFO messages
  (visible by default)
* Known crashes generate error messages, but are not fatal
  (unless --strict mode is used)
* Unknown crashes generate fatal error messages

Having an updated whitelist of known clean errors is useful to make the
script less verbose and run faster when in --quick mode, but the
whitelist doesn't need to be always up to date.

c0644771eb qapi: Reject alternates that can't work with keyval_parse()
Alternates are sum types like unions, but use the JSON type on the
wire / QType in QObject instead of an explicit tag.  That's why we
require alternate members to have distinct QTypes.

The recently introduced keyval_parse() (commit d454dbe) can only
produce string scalars.  The qobject_input_visitor_new_keyval() input
visitor mostly hides the difference, so code using a QObject input
visitor doesn't have to care whether its input was parsed from JSON or
KEY=VALUE,...  The difference leaks for alternates, as noted in commit
0ee9ae7: a non-string, non-enum scalar alternate value can't currently
be expressed.

In part, this is just our insufficiently sophisticated implementation.
Consider alternate type 'GuestFileWhence'.  It has an integer member
and a 'QGASeek' member.  The latter is an enumeration with values
'set', 'cur', 'end'.  The meaning of b=set, b=cur, b=end, b=0, b=1 and
so forth is perfectly obvious.  However, our current implementation
falls apart at run time for b=0, b=1, and so forth.  Fixable, but not
today; add a test case and a TODO comment.

Now consider an alternate type with a string and an integer member.
What's the meaning of a=42?  Is it the string "42" or the integer 42?
Whichever meaning you pick makes the other inexpressible.  This isn't
just an implementation problem, it's fundamental.  Our current
implementation will pick string.

So far, we haven't needed such alternates.  To make sure we stop and
think before we add one that cannot sanely work with keyval_parse(),
let's require alternate members to have sufficiently distinct
representation in KEY=VALUE,... syntax:

* A string member clashes with any other scalar member

* An enumeration member clashes with bool members when it has value
  'on' or 'off'.

* An enumeration member clashes with numeric members when it has a
  value that starts with '-', '+', or a decimal digit.  This is a
  rather lazy approximation of the actual number syntax accepted by
  the visitor.

  Note that enumeration values starting with '-' and '+' are rejected
  elsewhere already, but better safe than sorry.

fe2f74af2b scripts/qmp/qom-set: fix the value argument passed to srv.command()
When invoking the script with -s, we end up passing a bogus value
to QEMU:

$ ./scripts/qmp/qom-set -s /var/tmp/qmp-sock-exp /machine.accel kvm
{}
$ ./scripts/qmp/qom-get -s /var/tmp/qmp-sock-exp /machine.accel
/var/tmp/qmp-sock-exp

This happens because sys.argv[2] isn't necessarily the command line
argument that holds the value. It is sys.argv[4] when -s was also
passed.

Actually, the code already has a variable to handle that. This patch
simply uses it.

b7d5a9c2c6 scripts: Switch to more portable Perl shebang
The default NetBSD package manager is pkgsrc and it installs Perl
along other third party programs under custom and configurable prefix.
The default prefix for binary prebuilt packages is /usr/pkg, and the
Perl executable lands in /usr/pkg/bin/perl.

This change switches "/usr/bin/perl" to "/usr/bin/env perl" as it's
the most portable solution that should work for almost everybody.
Perl's executable is detected automatically.

This change switches -w option passed to the executable with more
modern "use warnings;" approach. There is no functional change to the
default behavior.

We have macros in place to make it less verbose to add a subtype
of QObject to both QDict and QList. While we have made cleanups
like this in the past (see commit fcfcd8ffc, for example), having
it be automated by Coccinelle makes it easier to maintain.

The script is separate from the cleanups, for ease of review and
backporting.  A later patch will then add further possible cleanups.

f3fddaf60b trace: disallow more than 10 arguments per trace event
The UST trace backend can only cope with upto 10 arguments. To ensure we
don't exceed the limit when UST is not compiled in, disallow more than
10 arguments upfront.

This prevents the case where:

    Optimize two trace events as one, adjust print format make

6e9389563e checkpatch: Disallow glib asserts in main code
Glib commit a6a875068779 (from 2013) made many of the glib assert
macros non-fatal if a flag is set.
This causes two problems:
  a) Compilers moan that your code is unsafe even though you've
     put an assert in before the point of use.
  b) Someone evil could, in a library, call
     g_test_set_nonfatal_assertions() and cause our assertions in
     important places not to fail and potentially allow memory overruns.

Ban most of the glib assertion functions (basically everything except
g_assert and g_assert_not_reached) except in tests/

This makes checkpatch gives an error such as:

  ERROR: Use g_assert or g_assert_not_reached
  #77: FILE: vl.c:4725:
  +    g_assert_cmpstr("Chocolate", >, "Cheese");

012b126de2 qapi: Fix a misleading parser error message
When choking on a token where an expression is expected, we report

Expected '"{", "[", string, boolean or "null"'.

Missed in commit e53188a.
