test-char.exe needs main-loop.o symbols, among others. Linking with
$(test-block-obj-y) brings what's necessary. We could try to eventually
strip to the minimum if needed.

Can I have a bit more background? I'm guessing this doesn't fix an
actual failure at the moment (probably due to one of the other files
dragging in stuff indirectly), but rather cleans up a latent problem
that would otherwise be exposed with patches later in the series (where
splitting files means the stuff is no longer dragged in indirectly, so
we need to mention it explicitly)?
Even mentioning _which_ main-loop.o symbol to be grepping for in
test-char.c might be helpful to the review.

At any rate, test-block-obj-y is simply test-io-obj-y plus the
additional block-obj-y, so you're merely adding an additional dependency
on block-obj-y files. While a nicer commit message may help, I don't
see any technical problem in the change, so here's a weak:

Ah, so it's an existing problem in mingw compilation (I missed that
part; I assumed that because it links fine on Linux that there was no
problem - without realizing that the mingw implementation of char
devices drags in more requirements thanks to the #ifdef's char drivers).
> I can add this linking error to the commit log if it helps.
Yes, listing the link failure in the commit message (either just those
two lines above, or the whole she-bang) helps tremendously.

Yep, all clear now.

And with the commit message improvement, it is now a strong R-b.

No need to allocate & copy fields, let's use static const struct
instead.

In fact, you are moving the struct from private to public, AND dropping
a member at the same time.

The old code reused the name copied during registration, the new code
uses kind to look up the name from the QAPI enum type. That means the
output changes: it now outputs the canonical name instead of the alias
name. I can live with that (even if the output is temporarily weird for
listing a canonical name more than once).

But this change means any driver that does NOT have a name in the QAPI
enum type CANNOT be constructed from the command line, at least for the
duration of this patch. Let's see what is impacted by this:

The old code registered two different names for a serial driver;

the new code just registers the SAME driver contents twice, but both
tied to the QAPI name "serial". Either we want _this_ patch to keep the
"tty" name around (but that's churn, because it does go away later in
the series when we add aliasing), or we can drop the second registration
as redundant, and just document that we temporarily lose access to the
aliased name until fixed in a later patch.

What's weird here is that CHARDEV_BACKEND_KIND_MEMORY and
CHARDEV_BACKEND_KIND_RINGBUF are also using the same callbacks, but this
time appear as separate names in the QAPI enum. A different approach
would be to modify qapi-schema.json to add 'tty':'ChardevHostdev' and
'parport':'ChardevHostdev' aliases, the way it already has a
'memory':ChardevRingbuf' alias, so that the above registrations that I
complained were duplicates could use the right enum values. But is it
really worth dirtying the QAPI with an enum value we don't want?
Conversely, should we remove 'memory' from QAPI as no longer supported
(yes, it breaks back-compat, but we've documented that new code should
not be using it)?
I still think you need more in the commit message to justify this code.
Option 1, minimizing code churn, documenting the temporary regression:
=====
No need to allocate & copy fields, let's use static const struct
instead.
Note that this promotes CharDriver to a public struct, but eliminates
the 'name' parameter in the process; this is because in most cases, we
can use the QAPI enum for ChardevBackend to come up with the same names,
with the only exceptions being older aliases 'tty' (for 'serial') and
'parport' (for 'parallel') where outputting the canonical name is better
anyways. This causes a temporary regression in the ability to create a
char driver from the command line using the older spellings, but that
will be fixed in a later patch that cleans up how aliases are handled.

Option 2, hoisting part of 6/20 earlier in the series to avoid the
temporary regression altogether:
=====
No need to allocate & copy fields, let's use static const struct
instead.
Note that this promotes CharDriver to a public struct, and replaces a
'name' parameter with an 'alias' field to handle the fact that we were
previously registering the 'serial' and 'parallel' drivers twice to pick
up their older 'tty' and 'parport' aliases (we still register the
'memory' driver as an alias for 'ringbuf', but that's because that alias
is public in the ChardevBackend QAPI type).

If you agree with either of those options, then you can add:
Reviewed-by: Eric Blake <eblake@redhat.com>
If anyone else has a strong opinion (such as changing qapi to add the
aliases 'tty' and 'parport', or even cleaning up qapi to remove 'memory'
in favor of 'ringbuf') on which of my two options is preferred, or even
going with a third option, then speak up now.

Number and kinds of backends is known at compile-time, use a fixed-sized
static array to simplify iterations & lookups. Add an alias field to the
CharDriver structure to cover the cases where we previously registered a
driver twice under two names.

Except that 5/20 didn't register twice under two names, so my option 2
on that patch was floating that portion of this patch earlier.

Dead assignment, since backends is a non-empty array so it will always
be overwritten by the first iteration of the following loop.

Simplify: 'if (i == ARRAY_SIZE(backends))' (whether cd is NULL at the
end of the loop is irrelevant, you know it is non-NULL if you broke
early on a match, but it is ALSO non-null if the last element of the
array was non-NULL; and right now, our last element of the array is the
'memory' alias which is unconditionally present and thus non-NULL; also,
i cannot grow greater than ARRAY_SIZE(), so == suffices rather than >=).

Hmm, I didn't account for this in the changes I suggested for option 2
of 5/20 (which means unless you further tweak it, I temporarily
regressed the command to omit the aliases - but then again, taking your
5/20 as-is without either of my options omits the aliases and lists the
canonical name twice).

Worth including %s and the user-provided name that failed lookup?

Unless you get rid of the duplicates (both my option 1 and option 2 of
5/20 did so), then you are registering 'serial/tty' once, and
'serial/NULL' a second time, where the second registration overwrites
the first, and so the alias doesn't work.

ok, it feels more correct. I'll move it at declaration instead if you don't mind.

This makes the code more declarative, and avoids duplicating the
information on all instances.

Minor, but it looks like there's not much to align to anymore, and we
could trim it to one space while touching it. But I don't care if it
stays the same, either, given the weird alignment on is_console a bit
earlier.

Again, depending on what we decide to do about the QAPI, we could delete
the 'memory' value from QMP and use .alias to still support it from the
command line, for just one driver instead of two here, if desired. But
not a show-stopper if we don't make that decision before this patch, though.

Will be some rebase churn here as you deal with my comments on earlier
patches, but they should be obvious enough that it shouldn't affect my
review.
With nits fixed,

Use a single allocation for CharDriverState, this avoids extra
allocations & pointers, and is a step towards more object-oriented
CharDriver.
Gtk console is a bit peculiar, gd_vc_chr_set_echo() used to have a
temporary VirtualConsole to save the echo bit. Instead now, we consider
whether vcd->console is set or not, and restore the echo bit saved in
VCDriverState when calling gd_vc_vte_init().
The casts added are temporary, they are replaced with QOM type-safe
macros in a later patch in this series.

Set errp to report errors up to the right monitor.
Use error_append_hint() to give hints about parameters on !qmp monitors,
instead of a direct fprintf() call.

Instead of registering a vc handler to allocate the Gtk VC Chardev,
overwrite the console.c char driver.
A later patch, when switching to QOM, will register a default console vc
QOM class if none has been registered before.

Might be worth a tweak to split this to two lines. Either way, R-b stands.

vc_chr_write() is more appropriate than _puts() since no newline is
appended, even though it's not used only as a callback.
Keep "qemu_chr_parse" prefix, most chardev parse functions use this
prefix atm.

Turn Chardev into Object.
qemu_chr_alloc() is replaced by the qemu_chardev_new() constructor. It
will call qemu_char_open() to open/intialize the chardev with the
ChardevCommon *backend settings.
The CharDriver::create() callback is turned into a ChardevClass::open()
which is called from the newly introduced qemu_chardev_open().
"chardev-gdb" and "chardev-hci" are internal chardev and aren't
creatable directly with -chardev. Use a new internal flag to disable
them. We may want to use TYPE_USER_CREATABLE interface instead, or
perhaps allow -chardev usage.
Although in general we keep typename and macros private, unless the type
is being used by some other file, in this patch, all types and common
helper macros for qemu-char.c are in char.h. This is to help transition
now (some types must be declared early, while some aren't shared) and
when splitting in several units. This is to be improved later.

I'm not familiar enough with the Object hierarchy to know if there is
any significant runtime cost to CHARDEV_GET_CLASS() that would warrant
capturing the output in a temporary variable, or if it is simple enough
that a compiler can already figure out that it is a reusable value
rather than computing it twice. Probably not worrying about, though,
unless it actually shows up in a hot spot on a trace.

char_get_class("tty", NULL) will fail, because that's merely an alias
name rather than the canonical "serial" name. Will that matter to any of
the code? I didn't spot anything, so I'm not letting it stop my review.
