[Pmwiki-users] simultaneous edit corruption?

[Wayne Lee]

hi,

does pmwiki support protecting
multiple folks from editing the
same page and corrupting the
other person's edits?

for example, open two browsers.
in browser A, click edit to edit
a page.  a little bit later, in browser
B, click edit, make changes, then
commit.  some time later still, edit
and commit changes for A.

it appears that B's changes will
be lost?

any way to protect against this?

could we place a timestamp in
the edit page when that page is
served and when that page is
commited, look at the timestamp --
if it is later than the last modified time
of the page, then abort it.


thanks,
wayne
