Has anyone else noticed that GWT Dev Mode is unbearably slow for WebAdmin? On my machine,
it's to the point where I might as well rebuild the entire application for every
change and not bother with Dev Mode. Pages take 4 or 5 minutes to render. Sometimes after
5 minutes, I just give up, close everything, and rebuild the app.
For now, I want to see if others have this issue. If we confirm that it's widespread,
we can discuss ways to mitigate.

Yes, this has been my developer experience since I joined the project.
The 5-6 minute page-loads are a standard but the GWT Dev Mode gets progressively
slower after each "refresh" that involves frontend recompilation. Also the
memory
consumption increases and after 5-th "refresh" or so I have to kill it and
recompile the whole engine.
Any improvement to current status would be much appreciated.

Yes, this has been my developer experience since I joined the project.
The 5-6 minute page-loads are a standard but the GWT Dev Mode gets
progressively
slower after each "refresh" that involves frontend recompilation. Also the
memory
consumption increases and after 5-th "refresh" or so I have to kill it and
recompile the whole engine.
AFAIK classic GWT Dev Mode is slow because it does recompilation on the fly.
Not sure if related, but debugging GUI code with "gwtdev" Maven profile
(activated through "gwt-debug" Makefile target) downgrades gwt-maven-plugin
version to 2.4.0, see http://gerrit.ovirt.org/#/c/22108/ for details.
We could try several things here:
1, use gwt-maven-plugin 2.5.1 instead of 2.4.0
in root pom.xml change
<gwt-maven-plugin.workingRefresh.version>2.4.0</gwt-maven-plugin.workingRefresh.version>
to
<gwt-maven-plugin.workingRefresh.version>${gwt.version}</gwt-maven-plugin.workingRefresh.version>
2, disable GWT persistent unit cache
in frontend/webadmin/modules/pom.xml find
<artifactId>gwt-maven-plugin</artifactId>
add <persistentunitcache>false</persistentunitcache> to
<configuration>
-or-
make gwt-debug [usual options]
DEV_EXTRA_BUILD_FLAGS="-Dgwt.persistentunitcache=false"
3, avoid using method-entry breakpoints as these are very slow [1]
disable Firebug during initial page load
[1] https://blogs.sourceallies.com/2013/04/java-method-breakpoints-are-evil/
Any improvement to current status would be much appreciated.
I'd like to push towards GWT Super Dev Mode [2] that avoids on-the-fly
recompilation, i.e. precompiled permutation debugged directly inside
given browser.

(Putting above on my GWT improvement task list.)

I agree with Lior. Alexander (cc'd) has a patch that will hopefully address it.

Master is back to its normal zippy self in GWT dev mode as of 8:25 EST Feb
27th 2014. With relative values for zippy. If you are annoyed by the slow GTW
dev mode be sure to fetch and rebase.

I'm afraid I need to resurrect this. I'm again seeing unbearable slowness with GWT
Dev Mode in webadmin on master. The first load is tolerable, and one or two refreshes are
ok, but after that it bogs down and is unusable.
Anyone else?

I'm afraid I need to resurrect this. I'm again seeing unbearable slowness
with GWT Dev Mode in webadmin on master. The first load is tolerable, and
one or two refreshes are ok, but after that it bogs down and is unusable.
Some suggestions (that have been already mentioned in this thread a while ago):
1, use gwt-maven-plugin 2.5.1 instead of 2.4.0
in root pom.xml change
<gwt-maven-plugin.workingRefresh.version>2.4.0</gwt-maven-plugin.workingRefresh.version>
to
<gwt-maven-plugin.workingRefresh.version>${gwt.version}</gwt-maven-plugin.workingRefresh.version>
2, disable GWT persistent unit cache
in frontend/webadmin/modules/pom.xml find
<artifactId>gwt-maven-plugin</artifactId>
add <persistentunitcache>false</persistentunitcache> to
<configuration>
-or-
make gwt-debug [usual options]
DEV_EXTRA_BUILD_FLAGS="-Dgwt.persistentunitcache=false"
3, try out GWT Super Dev Mode
Vojtech
Anyone else?

Some suggestions (that have been already mentioned in this thread a while
ago):
1, use gwt-maven-plugin 2.5.1 instead of 2.4.0
in root pom.xml change
<gwt-maven-plugin.workingRefresh.version>2.4.0</gwt-maven-plugin.workingRefresh.version>
to
<gwt-maven-plugin.workingRefresh.version>${gwt.version}</gwt-maven-plugin.workingRefresh.version>
2, disable GWT persistent unit cache
in frontend/webadmin/modules/pom.xml find
<artifactId>gwt-maven-plugin</artifactId>
add <persistentunitcache>false</persistentunitcache> to
<configuration>
-or-
make gwt-debug [usual options]
DEV_EXTRA_BUILD_FLAGS="-Dgwt.persistentunitcache=false"
3, try out GWT Super Dev Mode
Vojtech
Vojtech, you're not experiencing this slowness?

Vojtech, you're not experiencing this slowness?
In fact, I am .. (and I have quite powerful laptop)
The slowness is a combination of two factors, lots of UI code (for GWT compiler to
process) + on-the-fly recompilation of GWT Dev Mode. The "lots of code" factor
should be improved when we transition to REST API and introduce other UI improvements
(like alternative/dynamic i18n implementation, possibly UiCommon code refactoring, etc).
I've seen that people tend to use Super Dev Mode for basic debugging, falling back to
Classic (slow) Dev Mode for deeper debugging. (So far, I didn't have time to try out
Super Dev Mode myself.)

Alright. I'm trying out Super Dev Mode right now.

Hello,
it took me some time but I've managed to get GWT Super Dev Mode (codeserver) running.
Based on instructions at [1] + [2], I wrote a patch (attached) that works like this:
a, build Engine with WebAdmin GUI for Firefox & Chrome
engine_buildDir=/path/to/engine/build
engine_userAgent='gecko1_8,safari'
make install-dev PREFIX=$engine_buildDir
DEV_EXTRA_BUILD_FLAGS_GWT_DEFAULTS="-Dgwt.userAgent=$engine_userAgent"
BUILD_GWT_WEBADMIN=1
b, setup and start Engine
$engine_buildDir/bin/engine-setup
$engine_buildDir/share/ovirt-engine/services/ovirt-engine/ovirt-engine.py start
c, start GWT Super Dev Mode (codeserver)
make gwt-debug DEBUG_MODULE=webadmin
DEV_EXTRA_BUILD_FLAGS_GWT_DEFAULTS="-Dgwt.userAgent=$engine_userAgent"
DEV_GWT_SUPER_DEV_MODE=1
Notice that I've added new Makefile option -> DEV_GWT_SUPER_DEV_MODE (default is 0
which means classic Dev Mode)
During its startup, Super Dev Mode compiles WebAdmin (with source maps enabled) and prints
this:
[INFO] The code server is ready.
[INFO] Next, visit: http://vszocs.laptop:9876/
If your browser supports source maps, it means you'll be able to inspect Java source
code right inside the browser.
To enable source maps in Firefox:
http://www.codeproject.com/Articles/649271/How-to-Enable-Source-Maps-in-F...
To enable source maps in Chrome:
https://developers.google.com/chrome-developer-tools/docs/javascript-debu...
Now you can open http://127.0.0.1:9876/ and add "Dev Mode On" + "Dev Mode
Off" bookmarklets to your browser's bookmark bar.
After this, open http://127.0.0.1:8080/ovirt-engine/webadmin/WebAdmin.html --> must be
*without* "?gwt.codesvr=127.0.0.1:9997" stuff!
You now have compiled WebAdmin running in your browser, click "Dev Mode On"
bookmark in your browser's bookmark bar.
However, after clicking "Dev Mode On", WebAdmin is greyed-out, with title saying
"This module doesn't have Super Dev Mode enabled".
So apparently I'm missing some final piece of the puzzle here, maybe Greg can look
into this :)
EDIT: I think the solution is to pass "-Dgwt.devModeEnabled=true" during GWT
compilation in step a, mentioned above.
Because it's too late for me to think properly, I'll continue next week.
