New submission from Sergio Rael <sr...@onestic.com>:
I have found a deadlock using Python 3.6.10 that seems to have been solved on
3.7.x. probably related to capture groups. To reproduce the deadlock just do
something like this:
re.findall(
'\[et_pb_image(?:\w|=|"|\d|\.|
|_|\/)*src="(https?:\/\/(?:www\.)?\w*\.\w*(?:\/|\w|\d|\.|-)*\.(?:png|jpg|jpeg|gif))"(?:\w|=|"|\d|\.|
|_|\/|%|\|)*(?:\/?\])(?:\[\/et_pb_image\])?',
'[et_pb_image _builder_version="3.27.2"
src="https://www.somewhere.com/wp-content/uploads/2019/08/stabilizers.jpg";
box_shadow_horizontal_tablet="0px" box_shadow_vertical_tablet="0px"
box_shadow_blur_tablet="40px" box_shadow_spread_tablet="0px"
z_index_tablet="500" url="https://youtu.be/fTrC5gkyYBM"; url_new_window="on" /]',
)
I noticed that the problem is related to having two image urls on the content.
The regex says to look only for the one starting with "src=" so the one
starting with "url=" should be ignored. If "url=\"XXX\"" is removed from the
tag it works fine.
