[URGENT] A major malfunction detected

[museyooni]

I received more than 100 mails that notify me classroom posts are edited or deleted in multiple classrooms, however posts are not even changed a bit. There was no error message regarding mail sending, but 5~6 of 'change detected' or 'deletion detected', and it seems nonsense to get more than 100 mails which have all different notifications. Also, I got a new error message and I tried to copy here, and unfortunately, I lost it because copy and paste didn't worked for terminal.

I'm trying to resume these errors. I will inform you ASAP when I get specific error message.

[leesj-dev]

Ok. I haven't found the exact reason why this is happening. I will figure out for a solution ASAP.

[leesj-dev]

It is very odd, given that the bugs are not reproduced in my mac.

[leesj-dev]

Currently running through Terminal and I am not facing any errors yet. I am keep tracking for errors.

[leesj-dev]

Ok I found an error suddenly. The full code is the following:

It’s a “Element not clickable” exception, it’s because I clicked on other programs while executing the code.

[museyooni]

Did you get multiple emails like me?

[leesj-dev]

i disabled the email send code smtp.sendmail(naver_id, google_id, msg.as_string()) by adding a # to make it a comment before running the shell script, so the emails did not arrive.

[leesj-dev]

Ok, something happened when I was operating on a different program.

pdict_before =  {1: ('공지', '정용호', '3월 30일', '* 18기 3학년1학기 기하(정용호T) 수업참여 학생들 중<br>&nbsp; &nbsp;원격수업이 필요한 학생은&nbsp;<br>&nbsp; &nbsp;쌍곡선과 직선 수업동영상 학습에&nbsp;참여바랍니다.<br>* <b>차시예고: P.48~ 중단원, 대단원 마무리는 노트에 필이 후 검사받음</b>', '* 18기 3학년1학기 기하(정용호T) 수업참여 학생들 중\n   원격수업이 필요한 학생은 \n   쌍곡선과 직선 수업동영상 학습에 참여바랍니다.\n* 차시예고: P.48~ 중단원, 대단원 마무리는 노트에 필이 후 검사받음', ('https://drive.google.com/file/d/1PCklBUoFNss2hOZlnuHK1MOg4j1M6Ytn/view?usp=drive_web&authuser=0',))}

The only difference is the LINK (attachment). The attachExtractor did not work when I was using a different program on my Mac.

One more error happened; this time, pdict_after={}. Now we get WHY you received a bunch of emails – it’s because nothing was detected in pdict_after. We now have to solve how to fix these issues.

[leesj-dev]

Check google classroom for updated info.

[leesj-dev]

Try it one more time with the updated code. You may have to change the other files too, such as config.yaml, because most of the other files have been changed.

[leesj-dev]

To address the known issues as of now,

1. ElementClickIntrceptedException → we would replace every click() to send.keys(return) instead.
2. Detecting nothing in the page → we would have to check if certain element exists or change the time of implicity_wait.
3. Unable to find the element of the classroom name → since this must exist, we would use presenceOfElementLocated() or visibilityOfElementLocated() to wait until the element loads.

I will try these solutions later to see if the bugs can be fixed.

Great. If this solutions work, there is no need to make more sessions which cause higher CPU usage.
