It makes more sense to have ALL block size limit constraints in the same struct. Improve the documentation while at it.

We want to eventually stick request_alignment alongside other BlockLimits, but first, we must ensure it is populated at the same time as all other limits, rather than being a special case that is set only when a block is first opened. Note that when the user does not provide "align", then we were defaulting to bs->request_alignment - but at this stage in the initialization, that was always 512. We were also rejecting an explicit "align":0 from the user; this patch now allows that, as an explicit request for the default alignment (which may not always be 512 in the future). qemu-iotests 77 is particularly sensitive to the fact that we can specify an artificial alignment override in blkdebug, and that override must continue to work even when limits are refreshed on an already open device.

Commit 57cb38b3 included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: NMarkus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

In order to decide whether a blkdebug: filename can be produced or a json: one is necessary, blkdebug checked whether bs->options had more options than just "config", "x-image" or "image" (the latter including nested options). That doesn't work well when generic block layer options are present. This patch passes an option QDict to the driver that contains only driver-specific options, i.e. the options for the general block layer as well as child nodes are already filtered out. Works much better this way. Signed-off-by: NKevin Wolf <kwolf@redhat.com> Reviewed-by: NMax Reitz <mreitz@redhat.com> Reviewed-by: NAlberto Garcia <berto@igalia.com>

Now that we guarantee the user doesn't have any enum values beginning with a single underscore, we can use that for our own purposes. Renaming ENUM_MAX to ENUM__MAX makes it obvious that the sentinel is generated. This patch was mostly generated by applying a temporary patch: |diff --git a/scripts/qapi.py b/scripts/qapi.py |index e6d014b..b862ec9 100644 |--- a/scripts/qapi.py |+++ b/scripts/qapi.py |@@ -1570,6 +1570,7 @@ const char *const %(c_name)s_lookup[] = { | max_index = c_enum_const(name, 'MAX', prefix) | ret += mcgen(''' | [%(max_index)s] = NULL, |+// %(max_index)s | }; | ''', | max_index=max_index) then running: $ cat qapi-{types,event}.c tests/test-qapi-types.c | sed -n 's,^// \(.*\)MAX,s|\1MAX|\1_MAX|g,p' > list $ git grep -l _MAX | xargs sed -i -f list The only things not generated are the changes in scripts/qapi.py.

No need to keep two separate enums, where editing one is likely to forget the other. Now that we can specify a qapi enum prefix, we don't even have to change the bulk of the uses. get_event_by_name() could perhaps be replaced by qapi_enum_parse(), but I left that for another day.

Background: The blkdebug scripts are currently engineered so that when a debug event occurs, a prefilter browses a master list of parsed rules for a certain event and adds them to an "active list" of rules to be used for the forthcoming action, provided the events and state numbers match. Then, once the request is received, the last active rule is used to inject an error if certain parameters match. This active list is cleared every time the prefilter injects a new rule for the first time during a debug event. The "once" rule currently causes the error injection, if it is triggered, to only clear the active list. This is insufficient for preventing future injections of the same rule. Remedy: This patch /deletes/ the rule from the list that the prefilter browses, so it is gone for good. In V2, we remove only the rule of interest from the active list instead of allowing the "once" rule to clear the entire list of active rules. Impact: This affects iotests 026. Several ENOSPC tests that used "once" can be seen to have output that shows multiple failure messages. After this patch, the error messages tend to be smaller and less severe, but the injection can still be seen to be working. I have patched the expected output to expect the smaller error messages.

Instead of actually recreating the options from scratch, just reuse the options given for creating the BDS, which are the configuration file name and additional options. In case there are no additional options we can thus create a plain filename. This obviously results in a different output for qemu-iotest 099 which exactly tests this filename generation.

bdrv_make_empty() is currently only called if the current image represents an external snapshot that has been committed to its base image; it is therefore unlikely to have internal snapshots. In this case, bdrv_make_empty() can be greatly sped up by emptying the L1 and refcount table (while having the dirty flag set, which only works for compat=1.1) and creating a trivial refcount structure. If there are snapshots or for compat=0.10, fall back to the simple implementation (discard all clusters).
