ConcurrentModificationException in the compiler #12726

Probably it's the post-typer checks, There was just an unrelated improvement in that mechanism. |

ha, I haven't seen this one before either. the code in question (in |

I get to say jinx before Seth does? |
|
I owe @som-snytt a Coke it looks like we could make the code in question safe pretty easily, and without noticeably impacting performance (it's very much an outer loop), by replacing for (workItem <- unit.toCheck) workItem()with something like while (unit.toCheck.nonEmpty) {
val items = unit.toCheck.toList
unit.toCheck.clear()
for (workItem <- items) workItem()
}that kind of thing I am swamped this week, perhaps someone else would like to jump on it first? |
|
These are checks run (currently) after a file is typechecked (and just before unused warnings), so it should (perhaps) be obvious from debug output which file was just typechecked. A reproduction would be nice. I'll volunteer the easy fix as proposed. |
|
Yes, I do have output giving a strong indication of what has been just typechecked. But I have no idea what can I do to improve this issue on my side? Of course, as far as reproduction goes, I can link a commit in my project which fails, but

Can I somehow compile just those two files against current 2.13.10 and put them in bootclasspath? |
|
I don't know the simplest way to put a couple of class files on sbt's class path, if that is the question. Usually I wind up publishing a local jar to include in the build. I will try to enumerate when it adds "post-typer" work items and which might incur such tasks recursively. I think if it tries to add a work item after typer has run, it should just execute it immediately. (I tried the enumeration yesterday but fell asleep.) |
|
I was asking if the two files will pose any conflicts with the existing code base, or can I just replace those two without making my own version of the compiler, but I see I can't, there is a |

Once there's an open PR, you'll be able to test the PR validation snapshot; and once the PR is merged, you'll be able to use the next nightly. |
|
Out of the fire and into the frying pan... |
|
A JVM thread dump would show where in the compiler code the cycle is. Perhaps the same file is getting adding to |
|
It doesn't try to run "extra" checks but errors. (I haven't concocted a test yet.) If @noresttherein points me to a repo, I'd be happy to give it a shot. The PR includes extra enhancements, any breakage is possible. I see activity on Also, are you quite sure you don't want to call it |
|
Sorry, it was getting late yesterday and I just didn't have the strength to tackle it.
I suspect there may be an abstract type projection going on here. Here is the stack trace of the compiler thread: How to make a collapsible element here? |
|
Sorry, concurrent posts. No, Now that I know the file ( I am not sure however that it is even related to this issue, although I find it suspect that neither of the lists of processed (i.e. listed warnings and errors) files in pure |
|
Thanks, I'll take a casual look. I know lrytz likes to debugger the compiler, so maybe I will go down that path. Your project link is lunked. (I just made up that word. I was redeploying lunk as in lunkhead, but there's also a word lunker for a big fish, TIL.) Edit: by lunked, I mean the URL is munged in the link. I can reproduce the CME against HEAD easily, now I'll try the supposed fix. |

I also had to search for markdown collapse, after searching in vain for an old dotty ticket to demonstrate it. Use details tag with summary tag inside for description.
