src/slave/containerizer/provisioners/backends/copy.cpp (lines 105 - 113)


Wow, I guess I hadn't realized what you meant by "making sure the layers 
have the same basename" and I overlooked the fact that when multiple layers are 
applied every layer other than the 1st one is going to have the rootfs dir 
already created...

I think it's too much of a restriction to impose the same basename for all 
rootfes and it's not the backend's position to know that they should all be the 
same.

Given that there is unfortunately no standard way of doing this, I think 
I'll be OK with either of the following two approaches:

1) The following two commands can make sure the source overwrites the 
target event if it is a diretory.

GNU cp:
cp -aT source target // -T makes sure the contents are copied.

OSX cp:
cp a source/ target // The trailing slash makes sure the contents instead 
of the directory is copied.

So we can do something like 

#ifdef __APPLE__
  source += "/"
#else
  options += "T"
#endif

2) Use your previous approach with "/*" expansion but with quotes around 
the paths.

Neither is ideal but is no worse than the system commands we are already 
invoking.

I am OK with either. What do you think?

Since the updateFramework is a new API and I can only think up of cases for 
revocable resources related with allocator, can we update this comments in 
future if there are more cases? Thaks.

I see that we already switched to AgentID in v1 API, but the V1 API was not 
finished. Is it possible that we keep slave here and fix this in another RR? Do 
you think that we need to file a new bug or epic to address this? Thanks.

Here I was updating to "host" to "slave" instead and want to address the issue 
of "slave"->"agent" in another patch, make sense?

I cite some code from allocator here, it seems that only hosts in whitelist can 
offer resources?

foreach (const SlaveID& slaveId, slaveIds) {
// Don't send offers for non-whitelisted and deactivated slaves.
if (!isWhitelisted(slaveId) || !slaves[slaveId].activated) {
  continue;
}

Sure, will update to the scheduler.proto file. Also update the information a 
bit as following, please show your comments if any. Thanks!
// The quiesce message from the framework will disable resource offers until a

So that we cleanup temporaries created in the SSLTest setup.

Great, thanks - I'd suggest to add this information to the javadoc:
```
// The quiesce message from the framework will disable resource offers until a 
Revive message clears the filter to enable resource offering.
// When the timeout expires, the frameworks will start receiving resource 
offers again.
```

Or something to this effect (I'm sorry, I'm not that familiar with this part 
yet, so I may have gotten the finer details wrong).

Looks great, thanks! I'll will get this commmitted for you shortly, left some 
comments for small adjustments I'll make before committing.


src/master/allocator/mesos/hierarchical.hpp (line 216)


You only used this in one location below? In general we've avoided typedefs 
since they require a bit more non-local reasoning at the point in which they 
are being used (i.e. what is a FilterSet? Turns out it's a hashset of Filter 
pointers).



src/master/allocator/mesos/hierarchical.hpp (line 1084)


Can we keep this newline?

Hey Guangya, the point of MESOS-1935 was to use these constant functions 
throughout the code base:

```
➜  mesos git:(master) ✗ grep -R 'Seconds(1)' src/tests
src/tests/containerizer/cgroups_tests.cpp:if (elapsed > Seconds(1)) {
src/tests/containerizer/docker_tests.cpp:docker->inspect(containerName, 
Seconds(1));
src/tests/containerizer/docker_tests.cpp:  inspect = 
docker->inspect(containerName, Seconds(1));
src/tests/containerizer/isolator_tests.cpp:  } while (waited < Seconds(1));
src/tests/containerizer/isolator_tests.cpp:  } while (waited < Seconds(1));
src/tests/containerizer/launch_tests.cpp:Clock::advance(Seconds(1));
src/tests/fault_tolerance_tests.cpp:  Clock::advance(Seconds(1)); // 
TODO(benh): Pull out constant from Slave.
src/tests/gc_tests.cpp:  Clock::advance(Seconds(1));
src/tests/gc_tests.cpp:Clock::advance(Seconds(1));
src/tests/health_check_tests.cpp:  Clock::advance(Seconds(1));
src/tests/limiter.hpp:  MockRateLimiter() : process::RateLimiter(1, Seconds(1)) 
{}
src/tests/log_tests.cpp:  EXPECT_GT(Seconds(1), stopwatch.elapsed());
src/tests/log_tests.cpp:  Clock::advance(Seconds(1));
src/tests/log_tests.cpp:  Clock::advance(Seconds(1));
src/tests/master_tests.cpp:  Clock::advance(Seconds(1));
src/tests/rate_limiting_tests.cpp:Clock::advance(Seconds(1));
src/tests/rate_limiting_tests.cpp:Clock::advance(Seconds(1));

src/tests/slave_recovery_tests.cpp:Clock::advance(Seconds(1));
src/tests/slave_recovery_tests.cpp:Clock::advance(Seconds(1));
src/tests/slave_recovery_tests.cpp:Clock::advance(Seconds(1));
src/tests/slave_recovery_tests.cpp:Clock::advance(Seconds(1));

```

Some of these can be replaced by the MAX_REAP_INTERVAL(), for example, this one:

Thanks Marco. Here the filter is just a refused time out, when this time out 
reached, the frameworks can get resource offers again. Quiesce offer will set 
filters to frameworks to disable resource offers and revive offer will clear 
the filter to enable resource offering. The quiesce offer will also be revived 
when the filter time out reached.

Thanks for testing this!


src/tests/containerizer/perf_tests.cpp (line 67)


This one is never instantiated!



src/tests/containerizer/perf_tests.cpp (line 85)


All of these classes should include Perf in the name, otherwise these are 
not clear in the test results:

ParseCgroups/ParseCgroupsTest.ParseCgroups/0

How about:

Version/PerfCgroupsTest.Parse/0



src/tests/containerizer/perf_tests.cpp (lines 113 - 131)


To be consistent with the other code, please instantiate right after the 
class definition, rather than the test definition. i.e. move this up to right 
below the ParseCgroupsTest class.

Ditto for the others.



src/tests/containerizer/perf_tests.cpp (lines 153 - 164)


I don't think you need the comments here.

Also, shouldn't you do s/4.1.0/4.0.0/ here?

Ditto for the other instantiations.

Well, I am assuming that the `filters` here will take a conditional action 
based on a `Predicate`? (I am sorry, I don't really know what the `Filters` are 
for here - this was part of what I was asking for more documentation about this 
- please assume that the reader may not have access to all the source code - 
this is certainly true for people using Java bindings, who only usually look at 
the javadoc).

So, if you have method `foo()` that takes some `filters` to take some `action` 
on a given set of objects - the filters are "inclusive" if they will result in 
`action` being taken only on those objects for which `Predicate(Object) == 
true` - "exclusion" filters will instead **not** take action under the same 
circumstance.

Think of it as `-v` in `grep` :)

Re: Review Request 37462: Add support for version detection and parsing.

Looks good! Should be shippable after another round.


src/linux/perf.hpp (line 56)


Whoops, doesn't this comment belong on the parse function?



src/linux/perf.cpp (lines 278 - 281)


Hm.. can't we just add this as an overload of supported?

```
bool supported();
bool supported(const Version& version);
```

The first being only in the .cpp file, and let's stick it right below the 
existing supported to make the relationship clear.



src/linux/perf.cpp (lines 324 - 353)


To keep it clean, how about we just do the supported check initially, and 
avoid the 'check' lambda entirely:

```
if (!supported()) {
  return Failure("Perf is not supported");
}

internal::Perf* perf = new internal::Perf(argv);
Future output = perf->output();
spawn(perf, true);

auto parse = [start, duration](
const Version& version,
const string& output) ->
Future> {
  Try> result =
perf::parse(output, version);

  if (result.isError()) {
return Failure("Failed to parse perf sample: " + result.error());
  }

  foreachvalue (mesos::PerfStatistics& statistics, result.get()) {
statistics.set_timestamp(start.secs());
statistics.set_duration(duration.secs());
  }

  return result.get();
};

process::collect(perf::version(), output)
  .then(parse);
```

Note that there are races here either way, where the version we check might 
not match the version of perf that provided the sample.

These lambdas are getting ugly :(



src/linux/perf.cpp (line 391)


Let's just make an overload of supported that takes a version, see my 
comment above.



src/linux/perf.cpp (line 408)


Let's just omit these shas since we can just look at the tags instead:

https://github.com/torvalds/linux/blob/v4.0/tools/perf/perf.c

Ditto below.



src/linux/perf.cpp (lines 410 - 413)


How about just showing the two formats, and above where we call split() 
just saying that we use split because some fields may be empty (e.g. unit, see 
below). Seems a bit odd to show the empty unit cases here as extra cases.



src/linux/perf.cpp (lines 414 - 417)


Braces please :)

Also, this can just be a single statement?

```
if (tokens.size() == 4 || tokens.size() = 6) {
  ...
}
```



src/linux/perf.cpp (lines 422 - 423)


Braces please :)



src/linux/perf.cpp (lines 427 - 428)


Braces please :)



src/linux/perf.cpp (line 430)


The caller will print the line, let's just say what's wrong here (i.e. 
unexpected number of tokens?).

Also let's add a newline above this.



src/linux/perf.cpp (line 443)


Do you have a tool that is removing spaces on if statements, or?



src/tests/containerizer/perf_tests.cpp 


Why did this get removed?



src/tests/containerizer/perf_tests.cpp (line 69)


Please wrap these onto the next line, ditto below.

Review request for mesos and Ben Mahler.


Changes
---

Updated with bmahler's review comments.


Bugs: MESOS-3157
https://issues.apache.org/jira/browse/MESOS-3157


Repository: mesos


Description
---

Normally, the mesos-master performs allocation cycles in response
to protocol messages and cluster events. This ties the cost of
allocation to the amount of churn in the environment, which can led
to unpredictable performance. Add an option to disable this, meaning
that allocations are only every performed by the batch interval
task. This makes resource allocation a fixed cost, independent of
the amount of environmental churn.

We dont remove the const'ness of the original string. The original string 
object is unchanged. So now we have to decide if we want to copy the object 
when calling the function or you want to copy the object inside the function. 
The choice made here is to keep the style of "passing by const reference" and 
do teh copy inside the function.

We only explicitly handle certain status codes. We can expand the logci if 
required but currently its very strict. Also, how can it get into infinite 
recursion?

Could you explain the case where it can cause infinite recursion?

This is needed for uses that don't get flags from the master (eg. tests).

What's the benefits for this inline lambda vs just putting this code in the

I don't see you reuse it mulitple places and there is only one single call 
site.

Can you add some verbose logging especially when we're calling ourselves

This seems like code that we can get into trouble especially when the

200, or infinite recirusion starts happening, etc).



src/slave/containerizer/provisioners/docker/registry_client.cpp (line 219)


This should be Option right? Since we might not have a

Can you also comment on why we need this?

You should state the assumption in a resend that we don't expect a response

You did "Invalid Response :" + error in the bottom, and "Invalid Response

Let's just keep the same format, I suggest the former.

Also I think worth mentioning that this is matching the last response.

The identation seems off, I think you should probably just move the self()

Can you elaborate a bit more on what does the const reference buys us here 
since you end up removing the const-ness later ? 

Anyways if you still want to keep it why not name it as a continuation variable 
? Something similar to this:

string segment_(segment); // Remove const.

The implemenation gets changed dramatically in the commit 37200 (refactoring

Its effectively the same. const reference as method argument is just a good 
practice, thats all.

The mount options for overlayfs either takes one lowerdir, one upperdir and one 
workdir, or at least 2 lowerdirs. It's just how the function works.

The format would be dir1:dir2:dir3 etc. I'm just wondering is it possible to 
have the semi colon only appear between the directories? If I'm thinking about 
this correctly, strings::join will give me :dir1:dir2:dir3? Also since I'm 
stacking the layers in reverse from the comment above, does this still apply?

Possible values are uint64_t, double, "" and "".  
I'm not sure how useful it is to distingish between the last two but choosing 
between uint64_t and double cannot be done until we lookup the event.

Some notes before you rebase.


src/linux/perf.cpp (line 490)


Why not make this an Option and when it's  this the 
value is None?



src/linux/perf.cpp (line 498)


How about 'parse' to be consistent with how we've named these kinds of 
functions, perhaps making it a static member of Sample?

No need for inline here?



src/linux/perf.cpp (lines 500 - 512)


Indentation is off here, please have a look over the diff, also s/if(/if (/ 
:)



src/linux/perf.cpp (lines 501 - 504)


Don't forget to update this when you rebase.



src/linux/perf.cpp (line 511)


The caller is expected to print the line when composing the error message, 
the callee here should print why the line is bad.



src/linux/perf.cpp (lines 522 - 524)


Let's include the line contents in the error message by composing a message 
with the parse error:

```
return Error("Failed to parse perf sample line '" + line + "': " + 
parse.error());
```



src/linux/perf.cpp (lines 531 - 577)


Can you now use the -> operator here? Might also avoid the need to wrap 
these, although, the "" logic should be moved to 'parse()'.



src/linux/perf.cpp (lines 540 - 543)


Now that you have a parse function, let's put the  logic 
there as well.

Ship it!


Just some minor updates and we can get this committed. Thanks James!

Let's be clear in the description that this is motivated by some performance 
bugs in which event-based allocation will enqueue too many allocation rounds, 
and the allocator's performance is degraded due to the allocator's queue 
getting backed up. "Unpredictable performance" might not be clear to those who 
encounter this later :)


docs/configuration.md (lines 291 - 295)


Can you have this match the help message from flags.cpp? In particular, 
let's not tell people that this gives more predictable performance, as that is 
alluding to the fact that there is are performance bug(s) in the allocator, and 
we should fix those!



include/mesos/master/allocator.hpp (lines 43 - 56)


How about a 'struct' with no default constructor? Putting in these default 
values is a bit odd, since these fields should be coming from the master flags.



include/mesos/master/allocator.hpp (line 81)


How about s/allocationOptions/options/ here and everywhere else in this 
patch?



src/master/allocator/mesos/hierarchical.hpp (line 282)


Can you move this back up to below 'initialized' for now?

Review Request 38011: Maintenance Primitives: Use the parse> helper instead of a plural MachineID protobuf.

---

Review request for mesos, Alexander Rukletsov, Benjamin Hindman, Artem 
Harutyunyan, Joris Van Remoortere, and Michael Park.


Repository: mesos


Description
---

This removes the MachineIDs protobuf and changes it to instead use the 
RepeatedFieldPtr.
This also changes the maintenance primitives (alpha) API for /machine/up and 
/machine/down, which both take an array instead of an object now.

Re: Review Request 37993: Add explanatory comments for Allocator interface

include/mesos/master/allocator.hpp (lines 62 - 64)


I think we can kill this for brevity.



include/mesos/master/allocator.hpp (line 68)


Period in the end, please!



include/mesos/master/allocator.hpp (line 70)


I think we tend to merge detailed description with the summary in case both 
are very short. Here and below.

Also, let's mention that calling `initialize()` supposes to start 
allocation process.



include/mesos/master/allocator.hpp (line 72)


Please a period at the end!



include/mesos/master/allocator.hpp (line 87)


I think we prefer 's' at the end of the verb in such cases: `Add*s* a 
framework`.



include/mesos/master/allocator.hpp (line 89)


I think "register" is misleading. Allocator is notified that a new 
framework joins the cluster and is entitled to participate in resource sharing.



include/mesos/master/allocator.hpp (lines 105 - 106)


It's an interface, it cannot guarantee that resoruces will be released. We 
should document an expectation or a contract here. It's up to an allocator what 
to do in this case, the built-in just removes the framework from the fair share 
pool AFAIK. Let's reword.



include/mesos/master/allocator.hpp (line 108)


Let's capiralize `Id` for clarity. Here and everywhere.



include/mesos/master/allocator.hpp (line 117)


s/activated/active



include/mesos/master/allocator.hpp (lines 138 - 141)


This it true for the built-in allocator, but not necessarily for *any* 
allocator. Could you please reword putting an accent on *under what 
cercumstances* the method is called and maybe what an expected behaviour may be?



include/mesos/master/allocator.hpp (lines 154 - 158)


The comment about static reservations is important, let's keep it in the 
description. Again, let's add some information on when it's called.



include/mesos/master/allocator.hpp (line 170)


We try to switch to "agent" instead of "slave". Let's do it in the comments 
(here and everywhere). Also, let's have a note in the beginning of the doc 
saying "agent" is the new "slave".



include/mesos/master/allocator.hpp (line 212)


I think we remove only outstanding offers, right?



include/mesos/master/allocator.hpp (line 213)


... and resources recovered in a separate call.



include/mesos/master/allocator.hpp (line 221)


I think "agent" is more clear than "host" here. You maybe refered to the 
fact that the whitelist consists of hostnames, but that's slightly different 
and should be documented in the whitelist class.



include/mesos/master/allocator.hpp (line 225)


I don't think this is correct. AFAIK whitelist contains slaves that should 
not participate in the allocation, basically, they are deactivated.



include/mesos/master/allocator.hpp (lines 235 - 237)


Let's say here that a framework may request resources, but it is up to 
allocator whether and how to satisfy this request.



include/mesos/master/allocator.hpp (lines 280 - 283)


Also, when framework is deactivated.

Review request for mesos and Ben Mahler.


Changes
---

Rebased onto master and addressed some review comments.


Bugs: MESOS-3157
https://issues.apache.org/jira/browse/MESOS-3157


Repository: mesos


Description
---

Normally, the mesos-master performs allocation cycles in response
to protocol messages and cluster events. This ties the cost of
allocation to the amount of churn in the environment, which can led
to unpredictable performance. Add an option to disable this, meaning
that allocations are only every performed by the batch interval
task. This makes resource allocation a fixed cost, independent of
the amount of environmental churn.

I don't think that the `true`/`false` language makes this easier to read. I did 
update the language slightly and I hope that it clarifies the behaviour.

AFAICT these are spaces.

The problem with doing it in allocate() is that allocate() doesn't know whether 
it is being called in response to a cluster event, or by the periodic 
allocation cycle. We could pass down a flag or wrap it in some other way, but 
that did not seem any less clumsy.

Oh, I see. You are right, we should have adjusted the order if this was "our" 
file. However, the file is generated by the `protoc`, hence no manual tinkering 
is expected. I have filed

1. Yes, I followed test_framework.cpp; and I'll polish it by following 
persistent_volume_framework.cpp.
2. Regarding the executor, we can use test_executor.cpp to replase.
3. For State, it describe whether a slave has reserved resources; it's an 
example for the daemon on each slave host, such as NameNode.

I'll update the code to address 1 & 2; if any more comments, i'll continue to 
address them :).

Re: Review Request 37996: Added property manager

(Updated Sept. 1, 2015, 2:26 p.m.)


Review request for mesos and Benjamin Hindman.


Changes
---

Removes use of `auto` and for range loops.


Repository: mesos


Description
---

Introduces the `PathInheritedProperties` class which allows to create a tree 
where nodes can be tag with some property. This property is then inherited by 
children nodes.

Two behaviors are implemented, overriding, i.e. Adding a property to the child 
node of another node with a property already will result in the ancestor 
property being lost. The second behavior, accumulating, takes a function and 
accumulates
properties of all ancestors.

That's awesome, Guangya, thanks for doing this!

Some high-level comments before we dive into wording:
* We recently adopted a new style for public headers, please update the 
comments according to it 
(https://mesos.apache.org/documentation/latest/mesos-doxygen-style-guide/)
* We definitely need one more native speaker to review the comments. I think 
Adam B (adam-mesos) can be a good fit. Mind adding him to the list of reviewers?
