[Geoserver-devel] An interesting proposal in GeoNetwork land

Hi,
just stumbled upon this one:
https://github.com/geonetwork/core-geonetwork/wiki/Java-7-NIO-File

Even if the GeoServer build is not nearly as slow as the one described in GeoNetwork (a full build with extensions takes 18 minutes for me on a dated desktop PC),
I’m wondering if we could benefit from a similar approach

Cheers
Andrea

Hi Andrea

This is interesting. I am building on 4.0 Ghz cpu (8 cores but only one is used) , having 32 MB Ram and an SSD. The command

time mvn clean install -PallExtensions -fn

results in

real 37m38.270s
user 58m15.900s
sys 1m44.293s

Ho do you manage a build in 18 minutes ?

The Geonetwork approach sounds interesting, doing all the setup in a memory file system.

Cheers

I don't know? I assumed it was the operating system, as with a core i7 3rd
generation, 8GB of ram and a 512GB SSD,
but using Windows, I build in 28 minutes instead. However, that's a
notebook.

However... I assume you're on Linux too, so not sure. One signicant
difference is that I build with -T2, and with that
much RAM you have (I assume it's 32GB, not MB, right?) you could easily try
with -T4

Maybe it's the distro? Last week I tried with an Ubuntu 12.04 64bits, and
got 18 minutes, today I'm on Linux Mint 17
and I'm building in 18 minutes too (upgraded OS, same hardware, first
generation core i7 820, 8GB memory,
2TB hybrid hard drive with 32 GB of integrated SSD acting as a cache).

Cheers
Andrea

By the way, my full build command is:

mvn clean install -T2 -nsu -Prelease

This assumes that you also have a fresh local GeoTools build, which in my
experience is
worth having since fetching the jars from the net is going to be slower
than doing a "mvn clean install -T4 -Dall -DskipTests"
locally to build the latest and greatest)

This presumably locks you into Java 7? (not a problem for me).

Notice: This email and any attachments are confidential.
If received in error please destroy and immediately notify us.
Do not copy or disclose the contents.

I understand the motivation behind the approach but looks unnecessarily complicated to me.

We do something similar in GeoGig with a different approach, that IMHO is saner.

The thing is to always use a Junit 4 TemporaryFolder

For example:

class SomeTest{

@anonymised.com

public TemporaryFolder tmpDir = new TemporaryFolder();

@anonymised.com

public void setUp(){

File baseDir = tmpDir.getRoot();

setUpTest(baseDir);

}

}

And that’s all. The TemporaryFolder will clean up itself when the test finishes.

Whether it runs on /tmp, ${project.dir}/target, or any other path is a matter of parametrizing a maven property:

${project.build.directory} ... org.apache.maven.plugins maven-surefire-plugin ..... ${test.tmpDir}

</plugin

Then run mvn clean install -Dtest.tmpDir=/dev/shm, or wherever you have a ram disk mounted.

The difficulty with both the geotools and geoserver builds is that a lot of tests create temporary directories/files directly inside the project’s “target” directory.

They both also leave a lot of dangling files on /tmp (or wherever java.io.tmpdir points to). This has been a problem on the build server before, as they accumulate and can exhaust the filesystem.

I think it’d be a better fix for the geoserver unit tests code base to avoid such manual creation of temporary folders under target and rely on TemporaryFolder.

Eh, I thought about it, but not sure I have enough RAM on my machines to
actually dedicate a portion of it
to a RAMDISK (8GB are starting to be pretty tight these days, especially
with 150+ projects loaded in Eclipse
and the occasional virtual machine running).

Do you have an idea of how big of a RAM disk we'd need? Would a few hundred
MB work?
I guess I could stand up one during the build, and have it been tear down
when the build ends

On Linux you don’t need to set up a ramdisk with a fixed size. Instead, mount it as tmpfs and it’ll be dynamic and fall back to swap space if need be <http://en.wikipedia.org/wiki/Tmpfs>

At ares.boundlessgeo.com we have it like this in /etc/fstab
tmpfs /mnt/memtmp tmpfs size=512m,nosuid,rw,auto,nouser,sync,relatime,mode=01777 0 0

And the geogig build is configured to run mvn clean install -Dtest.tmpDir=/mnt/memtmp

Good information. Do you know if there is anything similar for Windows?

Trying this out should not be too hard, we have a single class managing the

I know there are third party programs that allow to create a ramdisk. Never
used one myself, but a google search for "windows ramdisk" throws up a good
number of hits. I'm guessing most/all of them will be fixed size ramdisks,
though I could be wrong.

Trying this out should not be too hard, we have a single class managing

Yeah that might get you 80% through. Plan ahead for non-standard set ups
headaches though.

One note on the maven flags:

By using -T 2C (not just T2), you get 2*number-of-cores parallelism. This really speeds up all the leaf dependencies.

On an Ubuntu 14.04 notebook, i7-4700MQ w/ 16GB and a 5400RPM spinning disk :slight_smile:

time mvn clean install -T 2C -nsu -Prelease

Hi Andrea

This is interesting. I am building on 4.0 Ghz cpu (8 cores but only one is used) , having 32 MB Ram and an SSD. The command

time mvn clean install -PallExtensions -fn

By the way, my full build command is:

mvn clean install -T2 -nsu -Prelease

This assumes that you also have a fresh local GeoTools build, which in my experience is
worth having since fetching the jars from the net is going to be slower than doing a “mvn clean install -T4 -Dall -DskipTests”
locally to build the latest and greatest)

Cheers

We are already on Java 7- you can drop Path use in behind ResourceStore … but it may not strictly be required. I already tried using ResourceStore with in-memory Mocking and it was quick.

Hi,
just stumbled upon this one:

Even if the GeoServer build is not nearly as slow as the one described in GeoNetwork (a full build with extensions takes 18 minutes for me on a dated desktop PC),
I’m wondering if we could benefit from a similar approach

Ciao Andrea,
although as you know I am in favour of using latest NIO features more
and more I am a bit concerned by the extent of this change which might
potentially mean a lot of work as well as a lot of instabilities.

Do you have a rough idea about the effort for this and also how would
you think this change should plan/conducted?

No, honestly I did not look much into it, I've only seen the proposal and
said "hey, this might be useful for GeoServer as well".

What Gabriel proposed could be quite a bit easier to try out, althought
of course it requires some changes at the OS level, which on Linux seem
harmless, on Windows might be a bit annoying or just not feasible if you
don't have a lot of RAM.
