Seems to be the same issue I run into
Missing entry point: web/forms/selecting_many_items_using_checkboxes/index.dart

After about 10-20 reloads I get this exception.

Thanks for the bug report.
This might be some caching gone astray.
But from the provided information it is hard to say exactly where the problem is.
Are you able to provide the program itself that causes the leak so we can investigate further?
from reflectable.dart.
I had this a few times when I worked on https://github.com/bwu-dart-contributing/polymer-dart-patterns/tree/0.17.0/web/forms/implementing_simple_autocompletion
I haven't tried if simply reloading without changing anything leads to OOM.
from reflectable.dart.
I updated the link, I forgot to link to the right branch (0.17.0).
from reflectable.dart.
I don't think that reloading unchanged files causes this because the transformer is not running. I did a lot of reloads and nothing happens. If you want to trigger it even small changes to the code like add/removing a comment to a print statement will cause this behavior after some iterations.
If it's still necessary I will try to provide a stripped down example but that will take some time for preparation.
from reflectable.dart.
I tried to perform a small experiment: I ran pub serve
in polymer-dart-patterns and loaded http://localhost:8080/layout_attributes/nesting_flex_layouts/index in dartium, and then did touch web/layout_attributes/nesting_flex_layouts/index.dart
every 20 seconds. This causes pub serve
to re-transform at each touch
for a while (saying 'Build completed successfully' about 9 times, then just '[Info from Reflectable..]' without 'Build'), and then it stopped (no more output in the terminal, anyway). At the same time we have a growing process (ps shows 10GB, 19GB, 28GB).
I'll experiment a little more with that.
from reflectable.dart.
Looks similar to my experience. At first Dartium starts to time out and after a few more retries it crashes with OOM.
from reflectable.dart.
@eernstg This should be the issue I'm experiencing.
@zoechi Is the OOM in Dartium, too?
from reflectable.dart.
@wienczny I'm not sure what you mean by "in Dartium".
pub serve
crashes with OOM and I use the reflectable transfomer only with Polymer 1.0.0-rc1 (client-side with Dartium).
from reflectable.dart.
@zoechi I was not sure whether the "it" from your post referred to pub or Dartium.
from reflectable.dart.
I found a similar issue. Might be related dart-archive/polymer-dart#401
from reflectable.dart.
I just landed a commit (8fbd269) that changes the transformer in a tiny way syntactically, but it makes a difference in practice: The test scenario that I ran yesterday where pub serve
serving 'http://localhost:8080/iron_validatable_behavior/index.html' to dartium could run 9 transformations before it started to fail now runs 150 transformations with no signs of trouble. The process still grows over time, but much less. The point is that we now use a single Resolvers
instance rather than one per transformation.
from reflectable.dart.
Sounds great!
