Bug ID: 43472
Summary: [ReplaceText] page limit option to circumvent server
limitations that will inevitably cause the incorrect
error: You must select at least one namespace
Product: MediaWiki extensions
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: Unprioritized
Component: ReplaceText
Assignee: [email protected]
Reporter: [email protected]

Classification: Unclassified
Mobile Platform: ---
ReplaceText can be enhanced to accept an optional limit for the number of pages
to return from the search, which would provide a way to resolve bug 38170
without needing to alter the server's PHP configuration. For example, today I
tried running ReplaceText on 70000 pages, and it's only a matter of time before
I'll try running it on millions of pages.
With a large enough replace operation, the incorrect namespace error is less of
a problem than the page size and load time at the "are you sure?" verification
stage of ReplaceText. That can render ReplaceText practically unusable even
when using the server configuration workaround suggested in bug 38170.
The workaround I'm currently using is to enter all the possible page prefixes
to ensure a predictable fraction of pages will be found and replaced. That
works for 70,000 pages. It probably won't work anymore for millions of pages,
simply because the fraction of pages will still be too large to produce a
reasonably verification page size and load time.
This problem could also be helped with a "skip verification page" option, but
given the power of ReplaceText, skipping the verification page is probably
foolish.
