URL and anchor naming
---------------------
/$INBOX/?r=$GIT_COMMIT -> HTML only
/$INBOX/new.atom -> Atom feed
-#### Optional, relies on Search::Xapian
-/$INBOX/$MESSAGE_ID/t/ -> HTML content of thread
+#### Optional, relies on Search::Xapian (or Xapian SWIG binding)
+/$INBOX/$MESSAGE_ID/t/ -> HTML content of thread (nested)
+/$INBOX/$MESSAGE_ID/T/ -> HTML content of thread (flat)
anchors:
#u location of $MESSAGE_ID in URL
#m<SHA-1> per-message links, where <SHA-1> is of the Message-ID
of each message (stable)
#s<NUM> relative numeric position of message in thread (unstable)
+ #i<...> diffstat location for patch emails
+ #Z?<...> per-file diff header location for patch emails
/$INBOX/$MESSAGE_ID/t.atom -> Atom feed for thread
/$INBOX/$MESSAGE_ID/t.mbox.gz -> gzipped mbox of thread
+/$INBOX/$GIT_OID/s/ -> "git show" (via "git apply")
+ This endpoint requires "coderepo" entries configured for
+ a given inbox. It can recreate ("solve") blobs from
+ patch emails using Xapian and git-apply(1). It can also
+ display non-blob content, but that remains a
+ work-in-progress.
+
+/$INBOX/$GIT_OID/s/$FILENAME -> "git show", raw output
+ As above, but shows the raw (usually text/plain) output.
+
### Stable endpoints
/$INBOX/$MESSAGE_ID/ -> HTML content
anchors:
Plain text (raw message) endpoints display in the original encoding(s)
of the original email.
+Offline friendly
+----------------
+
+The "/t/", "/T/", "t.mbox.gz" endpoints are designed to be
+useful for reading long threads for users with intermittent
+connections or saved for offline viewing.
+
+Date displays are always absolute, not the "X hours ago"
+pattern commonly seen because readers may be reading a
+previously-saved or cached copy.
+
+HTML URLs end with '/' or "$FILENAME.html". The reason many
+URLs end with the '/' character is so it can trivially be saved
+to a directory via wget or similar tools as "index.html", making
+it easy to mirror all files ending in ".html" using any static
+web server.
