Unable to set break point

[gunawebs]

System details

RStudio Edition :Desktop
RStudio Version : 2024.04.0+735 (2024.04.0+735) 
OS Version      : 14.4.1 (23E224)
R Version       : R version 4.3.3 (2024-02-29) -- "Angel Food Cake"

Steps to reproduce the problem

Create any R code file with a function
Source the file
Add a breakpoint

Describe the problem in detail

Despite Sourcing the file, breakpoint is NOT placed
Just says "Breakpoints will be activated When this file is sourced"
But the file has ALREADY been sourced.
THIS issue wasn't there before I upgraded the rstudio to the latest version

Describe the behavior you expected

Expected Behaviour: Breakpoint will be placed

• [x ] I have read the guide for submitting good bug reports.
• [ x] I have installed the latest version of RStudio, and confirmed that the issue still persists.
• [ x] If I am reporting an RStudio crash, I have included a diagnostics report.
• [ x] I have done my best to include a minimal, self-contained set of instructions for consistently reproducing the issue.

IMPORTANT: please note that I have now deleted this version, and installed the earlier version:

Version 2023.12.1+402 (2023.12.1+402)

And breakpoints work JUST FINE

@gunawebs Thank you for raising this! I'm unable to reproduce the issue on either MacOS 14 or Windows 11. Can you please provide a minimal code example that results in the problem?

[gunawebs]

@ronblum As shared in screenshot above. I was just not able to set breakpoint, in a sourced file.
And once I installed the prior version, it worked just fine.

[ronblum]

@gunawebs I can't reproduce the problem based on the screenshot because part of the code is cut off on the right, it uses objects there were defined elsewhere, and there are at least 219 lines that aren't included.

Does this occur with any sourced file? For example, is it possible to set a breakpoint in the following code?

x <- 1
y <- 23
x + y

I encountered the same only in this latest rstudio version, you have to manually resource the function before the breakpoint is set, an any file.

@ronblum Yes, the issue is with all files. PLs see above comment from @sthawinke Too!

[ronblum]

@sthawinke Can you provide a simple reproducible example? And can you check whether this will cause the problem? I'm trying to find a simple example that I can use to reproduce, because I'm unable to so far. Also, does the problem occur even with this simple example?

x <- 1
y <- 23
x + y

[sthawinke]

I defined this simple function and just clicked in the margin to set a breakpoint. It is not active until I source again. This is not necessarily a bug, but a bit tedious and unlike previous Rstudio versions

[ronblum]

Thanks! I can reproduce the problem in 2023.03.2+454, 2023.12.1+402, and 2024.07.0-daily+131. So this has always been a requirement. Note this only affects the function; when adding something outside of the function like

a <- 8
a

the breakpoints will work. This is by design, and only the newly defined functions that are affected. We'll look into whether changing this is doable.
