|

|
||||
In docutils 0.13, the return type of get_column_widths method of the
|
||||
Table directive has changed [1], which breaks our flat-table directive
|
||||
and leads to a TypeError when trying to build the docs [2].
|
||||
|
||||
This patch adds support for the new return type, while keeping support
|
||||
for older docutils versions too.

Since patch_text_stop_machine() is called in stop_machine() which disables IRQ,

sleepable lock should be not used in this atomic context, so replace patch_lock

to raw lock.
