cq-editor console stops working on Windows when fed a line with a SyntaxError #275

Open carribeiro opened 3 years ago

carribeiro commented 3 years ago

UPDATE

I got this bug after copying a path name on the console without doubling the slashes. Now I did another test and any SyntaxError causes the same problem. For example, simply typing 1 +& 2 breaks the console and requires a restart.

Original report

When a string with a broken escape sequence is input into console, cq-editor freezes for a moment (about 15 seconds in my PC). After some time it unfreezes and shows a log in the log viewer. However the console becomes unusable after that until I restart cq-editor. Lines are not interpreted anymore..

Sequence on the console (steps to reproduce)

In [1]: s = "abc"

In [2]:print(s)
abc

In [3]: s = "C:\Users\Atual\Google Drive\"
## freezes for about 15 seconds, no output ##

In [4]: print(s)
## freezes for about 15 seconds, no output ##

In [5]: s = "abc"
## freezes again ##

In [5]:print(s)
## freezes again, no output ##

I get a SyntaxError on Linux, will check on Windows

SyntaxError: EOL while scanning string literal
carribeiro commented 3 years ago

In fact, it HAS to issue a SyntaxError because we're feeding a broken statement to the interpreter with unbalanced quotes.

The problem is in the handling of the error. If you try the same on IPython, it gives the same message (of course as it is really a syntax error), but it keeps working. In this case something breaks inside cq-editor (at least on Windows) and it stops working to the point where you need to close & reopen cq-editor.

adam-urbanczyk commented 3 years ago

I cannot reproduce on windows - I just get a SyntaxError without the extra stuff. Please share your env specification (conda list).

carribeiro commented 3 years ago

Just an additional remark: I installed cq-editor twice on this PC and got the same error both times. I deleted the entire env and reinstalled later, to the same result.

carribeiro commented 3 years ago

After updating, now it works the same as for you. I was getting this problem for something like two weeks (since I've triggered it by mistake the first time). It was probably fixed somewhere upstream.

It's probably solved by now.

carribeiro commented 3 years ago

Too soon: 1 +& 2 still triggers the error ( a bit different this time).

SyntaxError: invalid syntax
carribeiro commented 3 years ago

I cannot reproduce on windows - I just get a SyntaxError without the extra stuff. Please share your env specification (conda list).

Try with this: 1 +& 2.

It still gives me the same problem.

adam-urbanczyk commented 3 years ago

I cannot reproduce this on my win PC.
