I'm not sure how the login script works, but you should be able to workaround the main issue by calling site.login() in your script:

import pywikibot
site = pywikibot.Site()
site.login()  # add this line, make sure username and password_file are defined in user-config.py
print(len(list(site.watched_pages())))

(this way, there should be no need to call pwb.py login before running the script)

Does this error also occur if you clone mirror repos ( https://github.com/wikimedia/pywikibot.git and https://github.com/wikimedia/pywikibot-i18n.git )?

Hi @Xqt,
Do you have access to pywikibot account on toolforge? (according to https://admin.toolforge.org/tool/pywikibot you do)

@Dalba it seems like the only piece of that code which you need is the following:

textarea[dir='ltr']
{
  direction:ltr !important;
}

Also interesting that adding

textarea[dir='rtl'], input[dir='rtl']
{
  direction:rtl !important;
}
textarea[dir='ltr'], input[dir='ltr']
{
  direction:ltr !important;
}

to Special:MyPage/common.css (as suggested by @Nightdevil on fawiki) does fix the issue for me.

More questions ... :)

Interesting, so, in a way, Parsoid allows writing whole sections inside a title. (not that I'm complaining, just a very unrealistic case I noted).

My premise was not true. There are several other queries that also have different formats.

https://www.mediawiki.org/wiki/API:Query#Example_5:_Batchcomplete mentions https://en.wikipedia.org/w/api.php?action=query&list=allimages&ailimit=3&format=jsonfm&formatversion=2 as an example of batchcomplete.

According to T154324#4164161 this should also be resolvable in pywikibot itself and I think https://gerrit.wikimedia.org/r/c/pywikibot/core/+/531589 will do it.

I'm curious to know if e.info contains any more details. Adding the following print statement to login.py should print it:

pywikibot-core[master]

diff --git a/pywikibot/login.py b/pywikibot/login.py

Mine is like this:

('HujiBot', BotPassword('HujiBot', 'REDACTED'))

@Huji, are having multiple pywikibot processes running on the same machine? Maybe this is the result of a race condition between them. If so, try it with a single process per user.

With BotPasswords, the CSRF error was not shown when the first block was done. When a second block was attempted, I got a Login failed error. Here are some relevant portions of the log:

Note that my bot successfully blocked 109.169.72.36 (and that is where the first login attempt happened and was successful); later, it tried to block 204.14.73.69 and, because each block must be preceded with a new login, it tried to log in again and failed. This is all using BotPasswords.

I believe it is because OAuth does not provide a way to ascertain the username associated with a consumer .. but should it matter?

Could you give BotParsswords or OAuth a try, please, and see if the same Invalid CSRF token error occurs or not?

Maybe switching to bot passwords will resolve this issue. I would suggest doing so. action=login has been long deprecated anyway.

Either T113120 isn't really solved or the behaviour is different from Python 2. The fix works for Python 3.4 only since rPWBC07ce5ab6fe67.

Apparently this is not limited to python 2, there is a failure on py341 on appveyor: https://ci.appveyor.com/project/Ladsgroup/pywikibot-g4xqx/builds/26087824/job/jm5299v53hmuib2q

Could not find a way to reproduce, maybe the source is somewhere other than getCookie...

BTW, I think the error message (...limited to members of the Interface administrators group..) should be changed to complain about the required user rights, not the user group.

Thanks Umherirrender. Because of the strange translation I had not noticed that one. Sorry for that. I needed to have editsitejs right.
(Also fixed the translation on translatewiki.net)
