Syntax coloring lost after load or reformat #243

Seems like eclipse-tm4e/tm4e#203 |
|
I don't get that exception though. |
|
Try http://download.eclipse.org/tm4e/snapshots/ which should reduce the chances for such problem to happen. It's still not perfect on TM4E side (it's not much tolerant to parallel changes such as editing when highlighting is computed), but it should be bette.r |
|
I am already on the latest tm4e snapshot. Doesn't happen in older versions. |
|
Yesterday's build?
|
|
Uhm, no. Eclipse says nothing new though. Perhaps the build hasn't made it to the update site? |
|
Is this the one? |
|
Yes, should be this one.
Are you still seeing the issue? As frequently as before?
|
|
Yep. Pretty much all the time. |
|
Can you please list the version of the various org.eclipse.tm4e *plugins*
you have installed ?
|
|
|
I have removed this one as it appears to be obsolete, no changes: |
|
I tried another crappy hack to TM4E avoid interruption of the syntax highlighting thread in case of error. It's quite ugly, but it may help. Would you like to give it a try? |
|
I could give it a shot, but what is exactly the problem? Is it a fundamental problem in how concurrency is handled? Can a "proper" solution for this issue be found for this issue or it is an architectural flaw? |
|
I don't know what is the root issue in your case, but in similar case I
see, the issue is that the document changes while TM4E is trying to parse
it and attempts to read a part of it that doesn't exist any more.
There are for sure more elegant ways to deal with it, but practically,
given the amount of workforce available, let's try a dummy one which
consists in catching and ignoring such errors.
|
Uhm. My machine is very fast and powerful. If there is a race condition, it might have one of the branches win more often.
Shouldn't TM4E then try again when the document is not changing? How hard it is to add a hotkey to reparse manually? I'm not happy to have to close and reopen each document in the editor every time this happens (which is basically all the time right now). |
|
Anyway, if there is something that can mitigate this, I'm ok to try it. |
That's somehow what the last build should implement.
It's not hard, but it's a workaround. I don't have enough time to build or review workarounds when there are actual issues to fix ;) |
|
@mickaelistria I have got a new TextMate Core snapshot about 15 minutes ago. So far it does look a bit better. Will keep testing throughout the day tomorrow and keep you posted. Thanks for now. |
|
Still getting this quite often, about 50% frequency. I've got two workarounds:
Both are awfully annoying. To be fair, given the bad experience I've had in the last couple of months, I'm planning to give CLion another shot. |
|
It's now ~100% again. It probably depends on the source file's length. Formatting in-editor is pretty much useless. I need to close and open editor windows again every single time I hit the format shortcut. If the file is large I lose track.
|
|
Problem seems less frequent with Eclipse 2019-06 |
|
I'm trying to work on it, but the lack of reproducer is really making it almost impossible to ensure fix works. Can you share an example project and minimal steps to reproduce it? |
|
I've pushed a cleanup patch with some behavior enhancements to tm4e that might help. You can install the new build of TM4E from http://download.eclipse.org/tm4e/snapshots/ and maybe this will help. |
|
I'm on Eclipse 2019-06 RC1 if it helps.
Cannot share the project I'm working on but the problem is widespread. I think the problem is more frequent if the affected file is large (>1000 lines?) |
|
Still open in Version: 2019-06 (4.12.0) Build id: 20190614-1200 |
|
If it helps, hitting |
|
Additional information: once this bug appears, syntax highlight stops working altogether for the affected editor, ie typing new code will always keep the code text black. The only workaround I found is to close and reopen the editor tab. |
|
Still open in Corrosion |
|
@mickaelistria Steps to reproduce:
This is just an example. The problem is widespread and can be easily reproduced by loading any Rust project and attempting to edit any nontrivial file (the file in the example is ~250 lines long). I could not reproduce on very small files (<50 lines). The problem may well be timing related so CPU speed may play a role (perhaps it's harder to reproduce in slower machines?). |
|
Can't reproduce here. I agree it seems like CPU performance have an impact. |
|
@mickaelistria I have got With this version I am no longer able to reproduce by simply adding/removing empty lines. However, the following would:
|
|
Update: the workaround detailed above makes #261 more frequent. |
|
Still open on 2019-08-12.
|
|
Still open on 2019-08-21 (after a flurry of lsp4j snapshot updates). |
|
LSP4J or LSP4E aren't involved here, as mentioned in #243 (comment) only TM4E is to be fixed. |
|
Still open on 2019-09-26 |
|
Problem still visible but with reduced frequency on 2019-10-31 |
|
Still open on 2020-01-28, with high frequency. |
|
As suggested by @mickaelistria I have managed to reproduce this with basically no effort (except for the SDK setup itself) in the Eclipse SDK. I am puzzled by the difficulty other people are encountering when attempting to reproduce this. I understand this bug can not be reproduced deterministically but this is its nature - it's probably a race condition which by nature cannot be triggered reliably. However, this bug is very frequent and very easy to reproduce.
Anyway, I have no idea how to proceed from here to track it :) Besides, I have attempted to load in the
|
To what precisely? |
|
I need help on general directions on what the next steps could be in order to pinpoint the problem. I have no idea on where to start looking/tracing/placing breakpoints. First of all, do I require to have the source code projects for Corrosion, lsp4e and tm4e all together? If yes, first of all I need to figure out how to get rid of all the errors. I've tried the target-platform files for all 3 projects but none produces a clear result. I've got latest |
|
I think the simplest is to
Then when doing "Run As > Eclipse application", you'll be able to put breakpoint into TM4E classes. |

Still open with Eclipse 2020-12 and matching Corrosion :( |
|
On the new june build of corrosion (1.2.1.202106081156) and eclipse 2020-12 doing Window -> Editor -> Split Editor (Vertical) for the first time since eclipse launch on a 200 line rust file results in the second pane consistently being uncolored. It also happens when I leave the vertical split open and restart eclipse. |
Please open a separate issue for that as it doesn't seem related to the original bug. |
|
There have been many fixes and improvements to tm4e so do you still face the issue with latest versions? |
|
I haven't used Corrosion for a while, I'll give this a shot though. |
|
Closing due to lack of interest. |
|
I have started using Corrosion again, this problem still occurs albeit slightly less frequently. |
I have observed Rust source syntax coloring loss occasionally, usually after:
Ctrl+Shift+FformattingClosing and reopening the affected file is an effective, albeit annoying, workaround.
