Hi,
I am getting the error
"Error triggers unlimited retry: Couldn't allocate new heap chunk
contiguously; increasing size to 512"
when I execute the following program
open List
table user_table: {ID: int, NAME: string} PRIMARY KEY ID

case projectRow of
ProjectRow (projectId, projectName, taskRows) =>

Hi,
I would like to show a busy indicator when there is an ongoing rpc. I was
wondering if there is a source that contains that information. Does anyone
know if is there such source?

Hi,
I have developed a GUI with a lot of push pin buttons that are associated
to boolean sources. When the button is pushed, it sets its source to true.
When the button is released, it sets its source to false. The problem I am
facing is that after pressing those buttons some times, the JavaScript

Hi Adam,
It took me some time, but after a lot of code removal (FFI, database and
logic) I believe I have a small test case that shows the bug. You can get
it with the command
git clone -b bug https://github.com/saulo2/timesheet-ur.git
To reproduce the bug, follow the steps below:
1) click the
n STYLE "display: initial"
else STYLE "display: none")
in
return
end

Hi,
I believe there is a substantial memory leak in the JavaScript runtime of
Ur/Web. To see it happening:
1) visit http://timesheet-ur.sauloaraujo.com:8080/TimeSheet/application

2) open the developer tools by pressing f12
3) click in the "Profiles" tab
4) click in the "Take He

Hi Adam,
You are welcome! I am happy to say that your patch also fixes the memory
leak. I believe there is another memory leak in the JavaScript runtime (see
the end of the previous message). I am gonna look into it.

Hi,
Does Ur/Web supports sharing types in signatures like in the code below?
signature A = sig
type t
end
signature B = sig
type t
end
signature C = sig
structure A1 : A
structure B1 : B
sharing type A1.t = B1.t
end
In case it is not supported, is there a way to accomplish something
con` instead of

Hi Michael,
Your definition of int2string is fine. For example, the code
fun int2string (i : int) : string = show i
val s = int2string 10
compiles without errors. I suspect the problem is in another part of your
code. The error message suggests that you have an expression that produces
a list w
; :: []

Hi Michael,
Thanks for sharing your game with the community. I skimmed its source code
and I did not found anything that I would qualify as a non-canonical use of
Ur/Web. However, beware that I am an Ur/Web beginner too :) Maybe you can
pinpoint which parts of the code you are afraid are non-canon
Hi Michael,
I am afraid I cannot give you "definitive" answers for much of your
questions. Anyway, I will try my best :)
- Is there a more convenient syntax for list construction than "1 :: 2 :: 3

Hi Artyon,
I believe that Liquibase satisfies, at least partially, your requirements.
In particular, it is able diff databases (
