When the Error API was created, we adopted the (unwritten) rule to
return void when the function returns no useful value on success,
unlike GError, which recommends to return true on success and false on
error then.
When a function returns a distinct error value, say false, a checked
call that passes the error up looks like
if (!frobnicate(..., errp)) {
handle the error...
}
When it returns void, we need
Error *err = NULL;
frobnicate(..., &err);
if (err) {
handle the error...
error_propagate(errp, err);
}
Not only is this more verbose, it also creates an Error object even
when @errp is null, &error_abort or &error_fatal.
People got tired of the additional boilerplate, and started to ignore
the unwritten rule. The result is confusion among developers about
the preferred usage.
This series adopts the GError rule (in writing), and updates a
substantial amount of code to honor the rule. Cuts the number of
error_propagate() calls nearly by half. The diffstat speaks for
itself.
Also available from my public repository
https://repo.or.cz/qemu/armbru.git on branch error-smooth.
v3:
* Rebased
* Fix patch ordering: old PATCH 19 becomes PATCH 37
* PATCH 03+13+25+27: Avoid long lines in Coccinelle script [Eric]
* PATCH 14: Fix commit message typo [Eric]
* PATCH 16: Unbreak opts_start_list(), qapi_clone_start_list(),
qapi_clone_start_alternate() [Vladimir]
* PATCH 24: Unbreak object_set_link_property() [Vladimir]
* PATCH 25+33+35: Move unrelated hunks from 25 to 33 and 35
[Vladimir], tweak line breaks
* PATCH 32: Have commit message point out the unnecessary
error_propagate() will be eliminated shortly [Eric]
* PATCH 33: Fix commit message typo [Eric]
* PATCH 35: Delete comment along with the assertion [Eric]
* Left for later: followup to fix nearby typos and such [Eric]
v2:
* Rebased
* Coccinelle scripts reworked, patches sliced and diced for
reviewability:
Old PATCH 03+17+23-24+35+38-39+42 split into "Use returned bool to
check for failure" parts [PATCH 03+13+17-18+25+28-29+42], and
"Eliminate error_propagate()" parts. The latter combined with old
PATCH 06-07+18-19+29+43 are now [PATCH 33-37]. The end result is
almost identical. Some R-bys dropped; sorry!
* Drop variables as they become unused [Vladimir]
* PATCH 01: Comment typos fixed [Greg]
* PATCH 09: Simplify further by cutting out variables [Eric]
* PATCH 11: opt_set() renamed to opt_validate(), redundant parameter
dropped [Vladimir], R-by kept
* PATCH 16: Comment typos fixed, indentation tidied up [Eric]
* PATCH 23: Assertion dropped [Eric], incorrect hunk backed out
* PATCH 26: Regenerated after rebase; note additional Coccinelle
hiccup in the commit message
* PATCH 27: Indentation tiedied up [Eric]
* Left for later: followup to fix nearby typos and such [Eric]

Show errp instead of &err where &err is actually unusual. Add a
missing declaration. Add a second error pileup example.

This merely codifies existing practice, with one exception: the rule
advising against returning void, where existing practice is mixed.
When the Error API was created, we adopted the (unwritten) rule to
return void when the function returns no useful value on success,
unlike GError, which recommends to return true on success and false on
error then.
When a function returns a distinct error value, say false, a checked
call that passes the error up looks like
if (!frobnicate(..., errp)) {
handle the error...
}
When it returns void, we need
Error *err = NULL;
frobnicate(..., &err);
if (err) {
handle the error...
error_propagate(errp, err);
}
Not only is this more verbose, it also creates an Error object even
when @errp is null, &error_abort or &error_fatal.
People got tired of the additional boilerplate, and started to ignore
the unwritten rule. The result is confusion among developers about
the preferred usage.
The written rule will hopefully reduce the confusion.
The remainder of this series will update a substantial amount of code
to honor the rule.

+ * - Functions that use Error to report errors have an Error **errp
+ * parameter. It should be the last parameter, except for functions
+ * taking variable arguments.
+ *
+ * - You may pass NULL to not receive the error, &error_abort to abort
+ * on error, &error_fatal to exit(1) on error, or a pointer to a
+ * variable containing NULL to receive the error.
+ *
+ * - The value of @errp should not affect control flow.
+ *
+ * - On success, the function should not use @errp. On failure, it
+ * should set a new error, e.g. with error_setg(errp, ...), or
+ * propagate an existing one, e.g. with error_propagate(errp, ...).
+ *
+ * - Whenever practical, also return a value that indicates success /
+ * failure. This can make the error checking more concise, and can
+ * avoid useless error object creation and destruction. Note that
+ * we still have many functions returning void. We recommend
+ * • bool-valued functions return true on success / false on failure,
+ * • pointer-valued functions return non-null / null pointer, and
+ * • integer-valued functions return non-negative / negative.
+ *
+ * How to:
+ *
* Create an error:
* error_setg(errp, "situation normal, all fouled up");

Chokes on hw/arm/musicpal.c's lcd_refresh() with the unhelpful error
message "no position information". Nothing to convert there; skipped.
Fails to convert hw/arm/armsse.c, because Coccinelle gets confused by
ARMSSE being used both as typedef and function-like macro there.
Converted manually.
A few line breaks tidied up manually.

macio_newworld_realize() effectively ignores ns->gpio realization
errors, leaking the Error object. Fortunately, macio_gpio_realize()
can't actually fail. Tidy up.

virtio_crypto_pci_realize() continues after realization of its
"virtio-crypto-device" fails. Only an object_property_set_link()
follows; looks harmless to me. Tidy up anyway: return after failure,
just like virtio_rng_pci_realize() does.

Convert uses like
opts = qemu_opts_create(..., &err);
if (err) {
...
}
to
opts = qemu_opts_create(..., &err);
if (!opts) {
...
}
Eliminate error_propagate() that are now unnecessary. Delete @err
that are now unused.

opt_set() frees its argument @value on failure. Slightly unclean;
functions ideally do nothing on failure.
To tidy this up, move opt_create() from opt_set() into its callers,
along with the cleanup. Rename opt_set() to opt_validate(), noting
its similarity to qemu_opts_validate(). Drop redundant parameter
@opts; use opt->opts instead.

When creating an image fails because the format doesn't support option
"backing_file" or "backing_fmt", bdrv_img_create() first has
qemu_opt_set() put a generic error into @local_err, then puts the real
error into @errp with error_setg(), and then propagates the former to
the latter, which throws away the generic error. A bit complicated,
but works.
Now that qemu_opt_set() returns a useful value, we can simply ignore
the generic error instead.

The previous commit enables conversion of
visit_foo(..., &err);
if (err) {
...
}
to
if (!visit_foo(..., errp)) {
...
}
for visitor functions that now return true / false on success / error.

The previous commit used Coccinelle to convert from checking the Error
object to checking the return value. Convert a few more manually.
Also tweak control flow in places to conform to the conventional "if
error bail out" pattern.

s390_pci_set_fid() sets zpci->fid_defined to true even when
visit_type_uint32() failed. Reproducer: "-device zpci,fid=junk".
Harmless in practice, because qdev_device_add() then fails, throwing
away @zpci. Fix it anyway.

Commit 2f262e06f0 lifted qdev_get_type() from qdev to object without
renaming it accordingly. Do that now.

Pass &error_abort instead of NULL where the returned value is
dereferenced or asserted to be non-null. Drop a now redundant
assertion.

Don't handle object_property_get_link() failure that can't happen
unless the programmer screwed up, pass &error_abort.

When using the Error object to check for error, we need to receive it
into a local variable, then propagate() it to @errp.
Using the return value permits allows receiving it straight to @errp.

The object_property_set_FOO() setters take property name and value in
an unusual order:
void object_property_set_FOO(Object *obj, FOO_TYPE value,
const char *name, Error **errp)
Having to pass value before name feels grating. Swap them.
Same for object_property_set(), object_property_get(), and
object_property_parse().
Convert callers with this Coccinelle script:
@@
identifier fun = {
object_property_get, object_property_parse, object_property_set_str,
object_property_set_link, object_property_set_bool,
object_property_set_int, object_property_set_uint, object_property_set,
object_property_set_qobject
};
expression obj, v, name, errp;
@@
- fun(obj, v, name, errp)
+ fun(obj, name, v, errp)
Chokes on hw/arm/musicpal.c's lcd_refresh() with the unhelpful error
message "no position information". Convert that one manually.
Fails to convert hw/arm/armsse.c, because Coccinelle gets confused by
ARMSSE being used both as typedef and function-like macro there.
Convert manually.
Fails to convert hw/rx/rx-gdbsim.c, because Coccinelle gets confused
by RXCPU being used both as typedef and function-like macro there.
Convert manually. The other files using RXCPU that way don't need
conversion.

The previous commit enables conversion of

}
for QOM functions that now return true / false on success / error.

The previous commit enables conversion of
qdev_prop_set_drive_err(..., &err);
if (err) {
...
}
to
if (!qdev_prop_set_drive_err(..., errp)) {

Coccinelle script:
@@
identifier fun = qdev_prop_set_drive_err;
expression list args;
typedef Error;
Error *err;
@@
- fun(args, &err);
- if (err)
+ if (!fun(args, &err))
{
...
}
One line break tidied up manually.

Replace
error_setg(&err, ...);
error_propagate(errp, err);
by
error_setg(errp, ...);
Related pattern:
if (...) {
error_setg(&err, ...);
goto out;
}
...
out:
error_propagate(errp, err);
return;
When all paths to label out are that way, replace by
if (...) {
error_setg(errp, ...);
return;
}
and delete the label along with the error_propagate().
When we have at most one other path that actually needs to propagate,
and maybe one at the end that where propagation is unnecessary, e.g.
foo(..., &err);
if (err) {
goto out;
}
...
bar(..., &err);
out:
error_propagate(errp, err);
return;
move the error_propagate() to where it's needed, like
if (...) {
foo(..., &err);
error_propagate(errp, err);
return;
}
...
bar(..., errp);
return;
and transform the error_setg() as above.
In some places, the transformation results in obviously unnecessary
error_propagate(). The next few commits will eliminate them.
Bonus: the elimination of gotos will make later patches in this series
easier to review.
Candidates for conversion tracked down with this Coccinelle script:
@@
identifier err, errp;
expression list args;
@@
- error_setg(&err, args);
+ error_setg(errp, args);
... when != err
error_propagate(errp, err);

When all we do with an Error we receive into a local variable is
propagating to somewhere else, we can just as well receive it there
right away. Convert
if (!foo(..., &err)) {
...
error_propagate(errp, err);
...
return ...
}
to
if (!foo(..., errp)) {
...
...
return ...
}
where nothing else needs @err. Coccinelle script:

constant c1, c2;

Not exactly elegant, I'm afraid.
The "when != lbl:" is necessary to avoid transforming
if (fun(args, &err)) {
goto out
}
...
out:
error_propagate(errp, err);
even though other paths to label out still need the error_propagate().
For an actual example, see sclp_realize().
Without the "when strict", Coccinelle transforms vfio_msix_setup(),
incorrectly. I don't know what exactly "when strict" does, only that
it helps here.
The match of return is narrower than what I want, but I can't figure
out how to express "return where the operand doesn't use @err". For
an example where it's too narrow, see vfio_intx_enable().
Silently fails to convert hw/arm/armsse.c, because Coccinelle gets
confused by ARMSSE being used both as typedef and function-like macro
there. Converted manually.
Line breaks tidied up manually. One nested declaration of @local_err
deleted manually. Preexisting unwanted blank line dropped in
hw/riscv/sifive_e.c.

When all we do with an Error we receive into a local variable is
propagating to somewhere else, we can just as well receive it there
right away. The previous commit did that with a Coccinelle script I
consider fairly trustworthy. This commit uses the same script with
the matching of return taken out, i.e. we convert
if (!foo(..., &err)) {
...
error_propagate(errp, err);
...
}
to
if (!foo(..., errp)) {
...
...
}
This is unsound: @err could still be read between afterwards. I don't
know how to express "no read of @err without an intervening write" in
Coccinelle. Instead, I manually double-checked for uses of @err.
Suboptimal line breaks tweaked manually. qdev_realize() simplified
further to placate scripts/checkpatch.pl.

When all we do with an Error we receive into a local variable is

propagating to somewhere else, we can just as well receive it there
right away, even when we need to keep error_propagate() for other
error paths.

When migrate_add_blocker(blocker, &errp) is followed by
error_propagate(errp, err), we can often just as well do
migrate_add_blocker(..., errp).
Do that with this Coccinelle script:
@@
expression blocker, err, errp;
expression ret;
@@
- ret = migrate_add_blocker(blocker, &err);
- if (err) {
+ ret = migrate_add_blocker(blocker, errp);
+ if (ret < 0) {
... when != err;
- error_propagate(errp, err);
...
}
@@
expression blocker, err, errp;
@@
- migrate_add_blocker(blocker, &err);
- if (err) {
+ if (migrate_add_blocker(blocker, errp) < 0) {
... when != err;
- error_propagate(errp, err);
...
}
Double-check @err is not used afterwards. Dereferencing it would be
use after free, but checking whether it's null would be legitimate.

When I sliced and diced my patches for v2, I dropped R-bys for patches
substantially altered. This one was borderline: the patch does strictly
less, and the work it no longer does us done by later patches.

away only in PATCH v3 33.
Would you like me to record your R-by for the patch's current version?

Thanks, that's useful.
Overall, the series looks ready to go from my perspective. It looks
like the changes from v2 were minimal enough that I don't have any R-b
to add.

I intend to drop the change from &err to errp, and update the commit
message accordingly.
error_setg(&err, ...) is indeed unusual, and I cleaned up several unwise
uses in PATCH 32+35+39. However, error_append_hint(errp, ...) is bad
advice until Vladimir's ERRP_AUTO_PROPAGATE() makes it work. No need to
get ahead of his work here.

The patch doesn't strictly do that since it also converts &err to errp.
This is okay because most of the changes also drop the associated
error_propagate(), with the exception of block/parallels.c for which
I had to check how local_err is used. As already noted by Vladimir
earlier this generates an harmless "no-op error_propagate", but it
could be worth mentioning that in the changelog for future reviews :)

Maybe some other potential candidates ?
chardev/char.c:
opts = qemu_opts_create(qemu_find_opts("chardev"), label, 1, &local_err);
if (local_err) {
error_report_err(local_err);
return NULL;
}
monitor/hmp-cmds.c:
opts = qemu_opts_from_qdict(qemu_find_opts("netdev"), qdict, &err);
if (err) {
goto out;
}
opts = qemu_opts_from_qdict(qemu_find_opts("object"), qdict, &err);
if (err) {
goto end;
}
With or without the extra changes:

Yes, and that's actually why I do it. I'll change the commit message to
say so:
to
opts = qemu_opts_create(..., errp);

Yes, error_propagate() becomes a no-op for one out of three error paths
through it. There's similar "partial no-opification" elsewhere in this
series, notably in PATCH 36.
Concrete suggestions for improving the commit message further are
welcome!

Don't fit my clarified commit message, because I can't replace &err by
errp there.

True. It's never been used. It was added together with
object_set_propv(), probably out of habit to always have both a ... and
the va_list function.

What about this ?
The change in block/parallels.c doesn't provide any clue on the usage
of local_err. As usual it is expected to be equal to NULL at the time
qemu_opts_create() is called, and the goto on the error path jumps
here:
fail_options:
error_propagate(errp, local_err);
So, if qemu_opts_create() fails, we end up doing error_propagate(errp, NULL)
which is a harmles no-op.

This could be possibly abbreviated to:
