This series moves all qerrors we have today to qapi-schema-errors.json and
generates the QERR_ macros and the qerror_table[] from it.
With this series, one doesn't have to manually add an error macro and the
matching table entry anymore. He or she just have to add the new error to
qapi-schema-errors.json.
There's only one small problem: the matching between error class name and
the (generated) error macro may not be clear for those not familirized with
qerrors. There are two possible solutions to this:
1. Add the generated macro name along with the error class name in
qapi-schema-json-errors.json; and/or
2. add docs/qapi-errors.txt to explain this in detail
This series is my first step on improving our error API.
o v2
- Small qapi-errors.py improvements
- Fix QERR_DEVICE_ENCRYPTED and QERR_AMBIGUOUS_PATH desc message

The socket error classes call a socket 'Sock', like in SockConnectFailed,
but the error macros call a socket SOCKET, like in QERR_SOCKET_CONNECT_FAILED.
This will cause problems when the error macros creation get automated,
because the macro name will be derived from the error class name.
Avoid that by renaming all QERR_SOCKET_* macros to QERR_SOCK_*.

The error class name is SockConnectInprogress, not SockConnectInProgress.
Rename the QERR_SOCK_CONNECT_IN_PROGRESS macro to QERR_SOCK_CONNECT_INPROGRESS
to reflect that, so that future error macro generation generates the
expected macro name.

Actually, renames it to 'object'. This must be what the original author
meant to write, as there's no 'object' in the error's data member.

A future commit will add a new qapi script which escapes that character.

This is the main error file, where all errors are defined and from
where error macros and whatnot will be automatically generated.
It contains all errors classes currently defined in qerror.[ch].

This script generates two files from qapi-schema-errors.json:
o qapi-errors.h: contains error macro definitions, eg. QERR_BASE_NOT_FOUND,
corresponds to most of today's qerror.h
o qapi-errors.c: contains the error table that currently exists in qerror.c

From: Luiz Capitulino @ 2012-07-25 16:54 UTC (permalink / raw)
To: qemu-devel; +Cc: pbonzini, aliguori, armbru, mdroth
Previous commits added qapi infrastructure to automatically generate
qerror macros and the qerror table from qapi-schema-errors.json.
This commit drops the current error macros from qerror.h and the error
table from qerror.c and use the generated ones instead.
Please, note that qapi-error.c is actually _included_ by qerror.c.
This is hacky, but the alternative is to make the table private to
qapi-error.c and generate functions to return table entries. I think that
doesn't pay much off.

The qerror.h file doesn't contain the macros anymore, the script should
check qapi-schema-errors.json instead.

Won't this cause us to look at string[-1] if
the input data has two ' characters in a row?
(also, maybe infinite loop if the input string has an
unterminated ' ?)

Non escaped? If you meant '' that's a zero length string and should work, but
if you meant 'foo '' bar' that's illegal, because ' characters should be escaped.
I don't doubt bad things will happen in that case, but in general we don't do
much error detection in the qapi scripts and improving that is beyond this
series' scope.

Yes, that's how I found out I needed this patch :)

I meant the zero length string case. yes. We come in with data = "''",
strip the first ' and set string to empty. Then in the first time
in the while loop data[0] is "'" but len(string) is 0 and so we'll
do string[-1] which I think will throw an exception.
...and yep, quick test of a nobbbled qapi-schema.json confirms:
$ python /home/pm215/src/qemu/qemu/scripts/qapi-types.py -h -o "." <

Try this (very lightly tested but seems to work):

For what it's worth, the orthodox way to lexically analyze strings is a
finite automaton. Utterly untested sketch:

Doesn't handle missing close quote gracefully; you may want to add that.

I'm afraid this isn't quite what you want. It's shorthand for two
separate rules with the same recipe[*]. Therefore, it's prone to run
the recipe twice, with make blissfully unaware that each of the two runs
clobbers the other file, too. Could conceivably lead to trouble with
parallel execution.
Paolo, Eric, maybe you can provide advice on how to best tell make that
a recipe generates multiple files.

"err_domain" is just a fancy name for the error symbol, i.e. what
qerror.h calls 'class', isn't it?
Is it the same as error_class in gen_error_decl_macros() below?

PRId64 matches existing qerror.h practice. Requires the macro's users
to pass suitable argument, which can be bothersome, but at least the
compiler helps with it.

colon is either empty or ', ', but never a colon. What about calling it

Wouldn't
if err.has_key('data'):
data = gen_error_macro_data_str(err['data'])
else:
data = gen_error_macro_data_str({})

Hmm, I would just do
qapi-errors.h: qapi-errors.c
qapi-errors.c: $(SRC_PATH)/qapi-schema-errors.json $(SRC_PATH)/scripts/qapi-errors.py
$(call quiet-command,$(PYTHON) $(SRC_PATH)/scripts/qapi-errors.py -o "." < $<, " GEN $@")
I think that's what I usually saw for bison (which creates both .h and .c).
A perhaps cleaner alternative is to add a stamp file, and make both files
depend on it.

Functions? Why can't you simply put
const QErrorStringTable qerror_table[NUMBER_OF_ERRORS];
into qapi-errors.h?
With a literal number instead of NUMBER_OF_ERRORS. If you suffer from
literal-phobia, you can also #define it instead.

I'd add the new rule in the commit that adds qapi-schema-errors.json,
and drop the old rules in the commit that deletes the old definitions.

Indeed, per
https://www.gnu.org/software/automake/manual/automake.html#Multiple-Outputs,
that is an appropriate solution for a 2-file generation. It is only
when you have more than two files where...

a stamp file makes more sense.

Or, since we depend on GNU make, we can use pattern rules instead
(untested):
%-errors.h %-errors.c: \
%(SRC_PATH)/%-schema-errors.json $(SRC_PATH)/srcipts/%-errors.py
$(call quiet-command,$(PYTHON) $(SRC_PATH)/scripts/qapi-errors.py -o
"." < $<, " GEN $@")

I started this script as a copy from the others qapi scripts and didn't
notice that, thanks for spotting it (fixed in v3).

This was also copied from others qapi scripts, but qapi-errors.py always
creates both files so I've dropped this.

I don't think so, but doesn't cause any harm either (and I'll maintain it as
the others qapi scripts do this too).

Because it's included by qerror.h, which is included by several files.
I don't like much the idea of including a .c file, but on the other hand
it's only included by qerror.c and qerror.c will probably die in the
near future.

And what harm does the declaration of qerror_table[] to those files?

The other qapi scripts need fixing then --- self-contradictory copyright

No, I'm just trying to understand what's going on, and asking you to
confirm my hypothesis.
But yes, same name for same thing would be nice.

We want to restrict qerror stuff as much as we can. Having it on a header
that's used by several files goes against that.
However, we just had a discussion on irc about not having the schema, so
this patch is probably going to change.
PS: Anthony will send a summary of the discussion to the list later.

for '', handle ' without matching '.

Have you tried squashing it into your commit? Apply on top of your
series, then git-rebase -i --autosquash master.
