[Bug 1527105] [NEW] Performance: drop HANDLE_BLOCK_INTERRUPTIONS support

[Daniel Axtens]

Public bug reported:

Dropping HANDLE_BLOCK_INTERRUPTIONS, which is only used by Apache 1, and
is dropped in PHP7, leads to a 4-6% speedup on artificial benchmarks and
a measurable speedup on real world applications.

I have written a patch to do this and submitted it upstream:
https://github.com/php/php-src/pull/1532

The PHP folk are a little hesitant to merge it in case there's anyone
downstream who has a custom server API that still uses the hooks. Ubuntu
doesn't ship Apache 1, nor does it have any custom server APIs, so it's
safe to be merged, giving all your users a speed boost.

All the details and the patch are in the upstream submission, and I'm
happy to answer any other questions or get it into whatever format is
most useful for you.

[Bug 1527162] [NEW] ssh-keygen ignores $HOME

[David Jones]

Public bug reported:

The manual for ssh-keygen claims that by default it will create a key in
~/.ssh/id_rsa

The convention used in /bin/sh (and other shells) is that ~/.ssh/id_rsa
is basically "$HOME/.ssh/id_rsa". So changing $HOME should change where
ssh-keygen writes its key.

But it does not. ssh-keygen seems to use the directory extracted from
/etc/passwd. In this terminal session, I change the value of $HOME to
illustrate this:

$ HOME=/tmp sh
$ cd ~
$ pwd
/tmp
$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/drj/.ssh/id_rsa): ^C

Versions etc:

Bug still persists.

one solution + this is ugly.

Normal mysql should correctly stop itself, without hacking an etc

[Bug 1526984] [NEW] ISST-LTE: root mpath device unavailable after installation

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Canonical FYI:

We appear to have a regression in the current 14.04 environment back to
the behavior originally outlined in Comment #10 of LP Bug 1429327.

---Problem---

A multipath install of 14.04.04 fails to create the install mpath
device on subsequent boots.  While the root filesystem ends up being
mounted on top of one of the path devices, other partitions on that
multipath device will not be automatically found.

---Additional details---

For one example host, the install disk was set up with a root and
swap partition:

Dec 14 21:37:55 disk-detect: create: mpath0 (35000c5007655a10f) undef IBM 
,ST300MP0064
Dec 14 21:37:55 disk-detect: size=279G features='0' hwhandler='0' wp=undef
Dec 14 21:37:55 disk-detect: |-+- policy='round-robin 0' prio=1 status=undef
Dec 14 21:37:55 disk-detect: | `- 0:0:7:0 sdc 8:32 undef ready running
Dec 14 21:37:55 disk-detect: `-+- policy='round-robin 0' prio=1 status=undef
Dec 14 21:37:55 disk-detect:   `- 1:0:3:0 sdd 8:48 undef ready running

The resulting fstab entries after install were:

/dev/mapper/mpath0-part2 /   ext4errors=remount-ro 0 1
/dev/mapper/mpath0-part3 noneswapsw0 0

In post-install boots, the multipath command appears to be executed
prior to any disks being discovered:

[0.710994] scsi 1:0:3:0: Resource path: 1/00-0E-0A

The system ends up mounting the root filesystem from /dev/sdc2,
and the post-mount run of multipath errors out creating mpath0:

[   10.056286] device-mapper: table: 252:0: multipath: error getting device
[   10.082644] device-mapper: table: 252:0: multipath: error getting device

[   10.796743] device-mapper: table: 252:2: multipath: error getting device

Since no other filesystems depend on mpath0 for this example config,
the system is able to boot, but lacks swap due to the missing swap
device.

The ubuntu changes either don't apply any longer due to upstream code

Retry-ssif-reads-as-needed.patch).

As of now only d/p/deb_bmc-watchdog_noRUN is required. Debian still
carries 0001-Fix-Wformat-security-warnings.patch and up_fixmanpages, but
those don't seem to be used during the package build.

Discussed this with Tiago, and while the patches against upstream should
be dropped, there is still an Ubuntu change to debian/rules

Does it need rebuilding? I believe this patch is against the go-runtime
so as long as the correct runtime version is installed this _should_
work. But I'll defer to @mwhudson.

[Bug 1503034] Re: Autofs 5.1.1-1ubuntu2 crashes with segfault on startup

[Adam Pocock]

I edited the description in line to make it mostly in line with the SRU
wiki. It's hard to provide a test case without having a full ldap client
and server configuration, plus an NFS system. I don't have access to the
server side configs so I can't provide those.

What extra information is necessary to get this into the Wily
repository?

** Description changed:

  I'm running Wily Beta 2, updated to the latest packages in the wily
  repository, with autofs-ldap using mounts stored in LDAP. On startup
  systemd immediately puts autofs into a failed state as it segfaults when
  reading the auto.master.
  
  Autofs & autofs-ldap version is 5.1.1-1ubuntu2.
  
  The log in journalctl looks like this:

  This occurs whenever the service is started with the line in auto.master
  which loads the ldap mounts. The line which causes the issue is
  
"+ldap:automountMapName=auto.master.linux,ou=automount,ou=,ou=,o=,dc=,dc=com",
  and this configuration worked on 14.04, 14.10 and 15.04.
+ 
+ [Impact] This bug prevents the autofs-ldap module from loading, and
+ causes it to segfault on startup. The proposed fix allows the module to
+ load normally. The fix initialises configuration cache before it is
+ first used (it is the access to the uninitialised cache which causes the
+ segfault).
+ 
+ [Test Case] Install the autofs-ldap package and have it read an
+ automount map from LDAP. The necessary auto.master & ldap.conf
+ configuration is dependent on the LDAP server that provides the
+ automount maps.
+ 
+ [Regression Potential] Given the shipped package does not load at all,
+ it can't be a regression on the shipped binary.

[Bug 1527105] Re: Performance: drop HANDLE_BLOCK_INTERRUPTIONS support

[Daniel Axtens]

Hi, thanks for the quick response.

I'm more than happy for this to wait for Xenial.

I wasn't aware there was going to be a 5.7. The page for 5.7 on the PHP
wiki suggests that it was a proposal that wasn't accepted:
https://wiki.php.net/rfc/php57 If I'm wrong about this then I'm happy to
work with upstream to get it into 5.7, but it looks like they want all
changes to go into php7 instead.

If you're referring to php7, then yes, this stuff does go away in PHP7.
However, I think there will still be a lot of people on php5 for some
time (think how long people stayed with php4!), so it'd be nice to have
that perform better.

I accept that there is risk associated with taking this patch. For two
reasons, I think the risk is minimal.

Firstly, I would be very surprised if people were compiling their custom
server backends against Ubuntu's source tree: I'd expect they'd compile
against mainline.

Secondly, even if they compiled against Ubuntu, they would need to
depend on HANDLE_BLOCK_INTERRUPTIONS to experience an issue.  Of all the
server APIs ever bundled with PHP, only Apache1 ever provided these
hooks. All of the (many!) other servers that PHP5 provided support for
didn't use these hooks.

If it were a 1 or 2% speed boost, I'd agree that it's not worth it.
However, given that it's closer to 5%, I think it's worth the work to
get it in.

Thanks again, and I'm happy to address any further concerns you have.

[Bug 1527162] Re: ssh-keygen ignores $HOME

[Robie Basak]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

I understand that shells generally expand ~ to $HOME, but I'm not sure
that automatically means the documentation is wrong, though I can see
how it could have misled you in this case. I'm also not sure that there
is consensus that changing $HOME should automatically change all program
behaviour, since as you point out nss (eg. getent) will still look up
/etc/passwd to find a different home directory. I'd expect that changing
one without changing the other would produce inconsistent results as you
have discovered.

In any case, that is just my opinion. I doubt we'd carry a patch in
Ubuntu to adjust this behaviour, so the best thing for you to do if you
want to make any progress on this is to report it to upstream and see
what they say. If you do, please link to your report here so others can
follow.

I'm marking this bug Won't Fix in Ubuntu because I don't think we should
carry a patch and I don't think it's likely to change any time soon, so
might as well set expectations correctly. But if it changes upstream or
in Debian, then Ubuntu will follow by default.

[Bug 1527162] Re: ssh-keygen ignores $HOME

[Robie Basak]

PS. it's also valid to say that the documentation should at least be
clarified, but I think my answer is the same in this case: it should go
upstream and we won't carry a patch, since the benefit doesn't justify
the additional maintenance burden in doing so.

[Bug 1527105] Re: Performance: drop HANDLE_BLOCK_INTERRUPTIONS support

[Robie Basak]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

If upstream don't consider this appropriate for the 5.6 branch then I am
hesitant to include it in Ubuntu.

In any case, I expect 5.7 to release in Xenial so the point could be
moot for Xenial. This isn't a certainty yet though, and I'd certainly be
happier carrying this in Xenial than in previous releases.

For previous Ubuntu releases, we do as much as possible to minimise
regression risk, so again I'm doubtful that this is justified. Users who
want the speed boost can upgrade to Xenial and 5.7 when it is released,
and in general this is the advertised path to get improvements, whereas
stable releases are expected to be stable. See
https://wiki.ubuntu.com/StableReleaseUpdates for our policy.

> nor does it have any custom server APIs

Is it possible that users will have third party custom compiled things
here?

This isn't by any means a final decision and I welcome further
discussion on this. My concern is that any change carries risk, and I'm
not sure a performance boost is worth that risk. Most users don't
require that since they are already deployed, and soon I'd expect new
deployments to be using Xenial where the patch is applied anyway.

[Impact]

This patch addresses an issue when a RabbitMQ cluster node goes down,
OpenStack services try to reconnect to another RabbitMQ node and then
re-create everything from scratch , and due to the 'auto-delete' flag is
set, race condition happened between re-create and delete on Exchange,
Queues, Bindings, which caused nova-compute and neutron agents are down.

[Test Case]

Note steps are for trusty-icehouse, including latest oslo.messaging
library (1.3.0-0ubuntu1.2 at the time of this writing).

Deploy an OpenStack cloud w/ multiple rabbit nodes and then abruptly
kill one of the rabbit nodes (e.g.  sudo service rabbitmq-server stop,
etc). Observe that the nova services and neutron agents do detect that
the node went down and report that they are reconnected, but messages
are still reporting as timed out, nova service-list/neutron agent-list
still reports compute and agents as down, etc.

[Regression Potential]

None.

The test described in the bug fails in Ubuntu 14.04.2.

The following packages were tried as well: libnuma1 2.0.9~rc5-1ubuntu3
and numactl  2.0.9~rc5-1ubuntu3

In all cases the test failed. The efix for 14.04.1 provided by Thierry
Fauck worked but it was not used  in 14.04.02

[Bug 1527105] [NEW] Performance: drop HANDLE_BLOCK_INTERRUPTIONS support

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Robie Basak (racb):

Dropping HANDLE_BLOCK_INTERRUPTIONS, which is only used by Apache 1, and
is dropped in PHP7, leads to a 4-6% speedup on artificial benchmarks and
a measurable speedup on real world applications.

I have written a patch to do this and submitted it upstream:
https://github.com/php/php-src/pull/1532

The PHP folk are a little hesitant to merge it in case there's anyone
downstream who has a custom server API that still uses the hooks. Ubuntu
doesn't ship Apache 1, nor does it have any custom server APIs, so it's
safe to be merged, giving all your users a speed boost.

All the details and the patch are in the upstream submission, and I'm
happy to answer any other questions or get it into whatever format is
most useful for you.

[Bug 1527044] [NEW] Update mutex from file to pthread

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Robie Basak (racb):

The default Mutex implementation used by Ubuntu's Apache package is file
locking. (See /etc/apache2/apache2.conf) This is slower than pthreads,
especially when using mpm_prefork.

The Apache project currently warns about pthreads being potentially
dangerous.[1] However, Linux has supported robust pthreads for many
years now,[2] so it's safe for Ubuntu to move to pthreads and reap the
performance benefits.

My tests on POWER8, VM and bare-metal, PHP and static files, show
something like a 1.5% to 3.5% performance gain for a one-line config
change.

[Bug 1527079] Re: Linux agent 2.0.14 may encounter unhandled error and exit accidently with Ubuntu 12.04, 14.04.

[Robie Basak]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

Looks like this is fixed upstream in 2.1.2 and this version is currently
in the process of being backported to all releases, which is being
tracked in bug 1523715.

Since Xenial is already on 2.1.2, the correct bug status is Fix
Released. Note that this doesn't reflect the status of existing
supported releases. I won't create separate tasks to track the existing
supported releases since they won't auto-close and due to bug 1523715
they will be fixed imminently anyway.

[Robie Basak]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

We could fix this in Xenial, thanks. I appreciate your performance
testing report, but is there anything from upstream that documents that
pthread mutexes with mpm_prefork are expected to be faster?

This should be reported to Debian too, so I'll leave a tag for that.
Again, we'd prefer to stay as close to Debian as possible.
