Oh what I mean is doing the following:
```
virtual void initialize() override {
  registry = ... // start the recovery.
}

Future recover() {
  return registry;
}
```

The second part of my comment above is just illustrating the code if we keep 
`registry` as an `Option` and `recovered` as a `Future`.

I was condering that we could do `undiscardable` in `apply` so that the caller 
can actually discard the recovery if they want to. Not sure if this is a valid 
use case though. Please drop it if you don't think so.

The thing that seems unintuitive to me is that `recover()` would return 
different futures at different times. May I ask what the reason to make 
`registry` a `Future` instead of an `Option`?

I get that we need this interface to retrieve data from the master's registrar. 
I was wondering if it is necessary or has a lot of advantages to store the RP 
manager registry in the master's registrar.

Actually I'm not sure if having an explicit list of targets that the definition 
takes effects would reduce the cost of code maintanance or it would increase 
the cost. It seems to me that people that are unfamiliar with this list could 
easily run into a case where a definition doesn't take effects on a new target 
and they will spend a lot of time debugging it.

Persistent volume creation is not working on Windows yet.

I'm okay to add some check about the validation of mising `agent_id`.

I'll see whether this is necessary. In the other test, this is necessary if we 
rely on offers to reflect operation result: to work around possible race 
condition between calling `allocation->updateAllocation()` and clock::advance.

Yup, thanks Akash.

This explains why the tests are passing ;)

I added the same tests than the ones for HS256 (i.e., validation in following 
cases: bad header, bad payload, unknown alg, unsupported alg, valid token etc.. 
and creation of a valid token). I also added a test to verify that the 
validation of a RS256 token fails when using the wrong public key.

I think that `TEST_F(SubprocessTest, PipeOutputToFileDescriptor)` adequately 
ensures this is working as inspected. Let me know what you think...

Hmmm... it's not clear to me why we don't drop other operations here as 
well. At the moment, this just means that we lose some logs, but once we land 
Gaston's patch (https://reviews.apache.org/r/66679/) dropping non-launch 
operations will also send operation feedback.

Could you update this block to drop non-launch operations?

Agreed, the authorization handling here would definitely benefit from a

There are some similar tests in both 'persistent_volume_tests.cpp' as well as 
'master_authorization_tests.cpp'.

Tests which do something very similar in the persistent volume tests are 
'PersistentVolumeTest.BadACLDropCreateAndDestroy' and 
'PersistentVolumeTest.GoodACLCreateThenDestroy'. It would be good to verify 
both the successful and failed authorization cases.

Historically, isolators were invoked in the order listed by
the operator in the `--isolation` flag. This changed to an
internal ordering in 6fb9c024, back to the operator ordering
in af474a6fa, and then to an undefined ordering in 9642d3c67b.

This commit switches back to an internal ordering for all the built-in
isolators. Custom isolators loaded in modules are run in operator order
after all the built-in ones. The rationale for an internal ordering is
expressed in MESOS-5581; basically we should not burden the operator
with having to figure out how to make the order correct. In the case of
custom isolators there's no way for us to know the correct ordering so
we make an arbitrary choice.

Posting this as an RFC. If reviewers are OK with the approach, I'll float it on

I'm a bit surprised this doesn't cause problems with tests like 
`ProtobufIOTest.Basic` and `OperationStatusUpdateManagerTests`.

Since you're dup-ing the FDs for each write, if the caller passes in the 
same FD for multiple calls, the original FD will retain its offset (near the 
beginning of the file) and should repeatedly overwrite the data each time 
`protobuf::write` is called.

Reading this a lot, I do not see we can safely retry failed authorization when 
operations are chained. In fact, I feel that we should look into refactoring 
the large code blob and extract authorization handling into its own block 
(rather than scattered through the `switch/case`).

That should be a separate patch though.

Will fix, but I have question/comments on operation authorization handling in 
`Master::_accept`:
1. We don't really check that `authorizations.size() == operations.size()`. My 
feeling is that this at least leaves space for error when devs adding new 
operations;
2. we allow part of the operations which are authorized to proceed while drop 
unauthorized operations. I'm not convinced it's either safe from security 
perspective or clear from user perspective;
3. I see some comments about `We may want to retry this failed authorization 
request rather than dropping it immediately.`. If authorization result is 
"Unavaiable" rather than "Rejected", should that be reflected from result type?

I fixed the '[&]', but I'd like to leave the parameter order as is. When you 
have a long message, this ordering makes the call site much easier to read.

Description
---

When the agents adds a new executor, creating the sandbox might
fail (most commonly because the requested task user is not present
on the agent). Rather than crashing the agent with a `CHECK`,
we report a `TASK_DROPPED` status update. This makes the behavior
more consistent with the nested containers API, which also reports
an error in this case.

I actually prefer this newline. Because the error handling is a big block I 
think it does make a difference to the legibility.

https://issues.apache.org/jira/browse/MESOS-8585


Repository: mesos


Description
---

Rather than crashing if the agent fails to create the executor
directory, propagate the error to the caller so that it can
handle it appropriately.

We could return the error for consistency, but we really don't expect this to 
fail. We know the target file exists, so the `rm` failing would be a 
consistency error.

I want to keep these two patches separate because it makes it a lot easier to 
reason about the changes in behavior. I've added a `CHECK_SOME` to this patch 
to preserve the original behavior (until the next patch).

Not in any new ways. Previously an I/O error creating the directory would cause 
the crash there. I didn't want to silently drop that error, so we would now 
crash here instead. There's sometehing fatally wrong if we can't write the 
checkpoint successfully.

Bugs: MESOS-8585
https://issues.apache.org/jira/browse/MESOS-8585

Description
---

Refactored the executor launch path so to make the conditional
logic clearer. After this there is just one place that adds and
launches a new executor and we will subsequently be able to add
error handling there.

I'd like to keep this (see reasons above) because I've seen race condition on 
offer otherwise. We can remove with other `UpdateSlaveMessage` in this test all 
together.

I feel keeping current form is easier to reason, and the condition upon `MOUNT` 
is reduced to only one test case.

See comments above: this is used to eliminate race condition between master and

The file check is definitely necessary IMO, because we are guaranteed that 
content of volume is not affected during grow/shrink, but I'm okay to use a 
file operation directly rather than a task to perform the check.

+1 for splitting the test.

w.r.t to directly creating volume from the very beginning, isn't persistent 
volume controlled by checkpointed info rather than `slaveFlags.resources`?

Will convert to file operation directly.

I think this will be the only test case which needs to skip `MOUNT`. It also 
makes some sense because there is no logical starting point for a framework to 
even construct a `GROW_VOLUME` message for `MOUNT`.

I still feel that the handling here could be better. we can discuss on next 
patch revision.

Yes this is necessary if we do not launch task in this test. we need to 
reliably know that `Allocator::updateAllocation` is called from master, and 
this message happens before that, so this `Future` ensures allocator has 
properly processed all operation conversions and next offer will contain the 
host and updated resources.

Thanks for the review. I'll combine this patch into r/66220 and address your

Actually the check happens before type of `MOUNT` so this conditional check can 
be safely removed.

Semantic already fixed in the other patch. I will fix the test to reflect your 
suggested semantic.

I am quite surprised at this, because yes that would be the implication. I'm

I see you have the code below in the patch

Can you add the comment below between this two lines?

// Master set the `launch_executor` flag and this is not a command task.
```



src/slave/slave.cpp

This comment seems not accurate, because we can also reach here in the 
legacy case where the master did not set the `launch_executor` flag, i.e., 
launching a new executor is not requested by master.

Ship it!




I'm a bit surprised by the behaviour you describe, i.e. cmake downloading and 
configuring third-party dependencies that are not going to be used. Am I 
correct in thinking that for a proper fix, we should wrap *every* third-party 
dependency into an analogous if-block?

I really would prefer, if possible, to forward declare `RSA_shared_ptr` 
here and leave in include in the cpp.

I'm not so sure we gain too much by declaring this typedef. Moreover, we 
use typedefs rather sparecely in the code base, so I would get away with it.

We don't use `auto` unless the type is obvious from the lhs (like a call to

Bugs: MESOS-8735
https://issues.apache.org/jira/browse/MESOS-8735


Repository: mesos


Description
---

In order to support recovering resource provider manager information
in the future, we need to adjust the construction of the manager to be
able to consume a registrar.

This patch lays the groundwork by adjusting interfaces and their
usage; we will make use of the passed on information in a following
patch.

This registrar and its matching process can work on generic storage
and is currently used to work on an agent's persist store.

Its name should not be tied the agent, so we rename the registrar in
this patch.

This is not used anywhere else in this file, let's just keep this instance as

That's what I wanted to do initially as well, but it really complicates 
resource providers as they would need to implement some retry logic.

As we currently do assume not too large numbers of resource providers elsewhere 
as well, I believe keeping pending subscribe requests in memory should be fine 
for now. I added a `TODO` regarding your suggested improvement.

We are in a lambda body here and capture `this` which in general is not safe 
(unless one uses `dispatch` or `defer`). We often do make member access or 
method calls explicit in such contexts to call out the "dangerous parts".

We already require users to `recover` registrars before being able to perform 
operations against them (like for other registrars), so I am not really sure I 
understand how what you suggest would help. Could you explain?

I added a comment and also fixed below `apply` to use `recover()` which would 
return the cached result, already guarded by `undiscarable`.

I replaced the direct access to `registry` with `recover` here which once 
recovered would just serve a cached result. Does that look more reasonable to 
you?

It is pretty explicit on the `apply` path above -- how about adding a 
`CHECK(registry->isReady())` for documentation here?

Updated the code like that.

I don't think so. Taking a value already implies that we take ownership of the 
passed `storage`, and to call this function any user would need to provide us 
with that exclusive ownership (e.g., by casting some local with `std::move`). 
All that restricting ourself to rvalues here would add is that it would enforce 
correct usage even for broken types which are only semantically non-copyable, 
but still define a copy constructor. Unfortunately `Owned` falls into that 
category (see MESOS-5122), but I prefer to explicitly move args when passing 
instead of polluting interfaces because of tech debt we will fix eventually.

The master registrar is different in that it is already recovered and we need 
to use it differently when retrieving its recovered state via above interface, 
see https://reviews.apache.org/r/66311//

We use the underscore to disambiguate the different names to readers. It is 
required below, but not here.

I think having these factory functions still adds value as they hide away 
non-trivial details.  The arguments pretty clearly communicate how they can be 
used, e.g., in the master we would not be able to transfer ownership of the 
underlying storage leaving only one possible factory to use.

Let's keep this as is, dropping.

Bugs: MESOS-8735
https://issues.apache.org/jira/browse/MESOS-8735


Repository: mesos


Description
---

By delaying the construction of the agent's resource provider manager
we prepare for a following patch introducing a dependency on the
resource provider manager on the agent's ID.

Depending on whether the agent was able to recover an agent ID from
its log or still needs to obtain on in a first registration with the
master, we can only construct the resource provider manager after
different points in the initialization of the agent. To capture the
common code we introduce a helper function performing the necessary
steps.

I moved this up to be grouped with the routes of `/api/v1` and 
`/api/v1/executor`.

I am not sure that is what is happening here. The assertion here just validates 
that no new additional resources from RPs enter while we haven't even 
initialized the RP manager. This should hold as RP resources can only appear 
after a RP has subscribed which requires the manager. I don't believe that this 
performs a very stringent check, and we just perform the easy check here.

I added a comment to that effect, PTAL.

This patch changes the way the storage backing an agent's resource
provider registrar is created: while before we created it implicitly
when constructing the registrar, we now consume storage passed on
construction.

Being able to explicitly inject the used storage simplifies testing.
