Subject: extindex: fix --reindex when blobs go missing
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b37373b6e4efab044b3b1922168345e340719e11;p=thirdparty%2Fpublic-inbox.git

extindex: fix --reindex when blobs go missing

Blobs in v2 repos may be purged, ensure we don't try to parse
non-existent blobs for List-IDs to remove from Xapian when they
go missing.  The invalid List-IDs will be removed in a later
stage of the reindex process.
