* support remapping of expired URLs similar to mailmap
(coordinate with git.git with this?)
-* POP3 server, since some webmail providers support external POP3:
- https://public-inbox.org/meta/20160411034104.GA7817@dcvr.yhbt.net/
- Perhaps make this depend solely the NNTP server and work as a proxy.
- Meaning users can run this without needing a full copy of the
- archives in a git repository.
-
-* HTTP and NNTP proxy support. Allow us to be a frontend for
+* HTTP, IMAP, NNTP, POP3 proxy support. Allow us to be a frontend for
firewalled off (or Tor-exclusive) instances. The use case is
- for offering a publically accessible IP with a cheap VPS,
+ for offering a publicly accessible IP with a cheap VPS,
yet storing large amounts of data on computers without a
public IP behind a home Internet connection.
-* support HTTP(S) CONNECT proxying to NNTP for users with
+* support HTTP(S) CONNECT proxying to IMAP/NNTP/POP3 for users with
firewall problems
* DHT (distributed hash table) for mapping Message-IDs to various
archive locations to avoid SPOF.
* optional Cache::FastMmap support so production deployments won't
- need Varnish (Varnish doesn't protect NNTP, either)
+ need Varnish (Varnish doesn't protect NNTP nor IMAP, either)
* dogfood and take advantage of new kernel APIs (while maintaining
portability to older Linux, free BSDs and maybe Hurd).
while retaining compatibility with old versions.
* Support more of RFC 3977 (NNTP)
-
-* Combined "super server" for NNTP/HTTP/POP3 to reduce memory overhead
+ Is there anything left for read-only support?
* Configurable linkification for per-inbox shorthands:
"$gmane/123456" could be configured to expand to the
- appropriate link pointing to the gmane.org list archives,
+ appropriate link pointing to the gmane.io list archives,
likewise "[Bug #123456]" could be configured to expand to
point to some project's bug tracker at http://example.com/bug/123456
* linkify thread skeletons better
https://public-inbox.org/git/6E3699DEA672430CAEA6DEFEDE6918F4@PhilipOakley/
-* low-memory Email::MIME replacement: currently we generate many
- allocations/strings for headers we never look at and slurp
- entire message bodies into memory. GMime+Inline::C could work.
+* Further lower mail parser memory usage. We still slurp entire
+ message bodies into memory and incur 2-3x overhead on
+ multipart messages. Inline::C (and maybe gmime) could work.
* use REQUEST_URI properly for CGI / mod_perl2 compatibility
with Message-IDs which include '%' (done?)
-* more and better test cases (use git fast-import to speed up creation)
+* better test cases, make faster by reusing more setup
+ code across tests
-* large mbox/Maildir/MH/NNTP spool import (see PublicInbox::Import)
+* large mbox/Maildir/MH/NNTP spool import (in lei, but not
+ for public-facing inboxes)
+
+* MH import support (read-only, at least)
* Read-only WebDAV interface to the git repo so it can be mounted
via davfs2 or fusedav to avoid full clones.
Sometimes an indexing bug only affects a handful of messages,
so it's not worth the trouble of doing a full reindex.
-* code repository integration (with cgit, gitweb, etc...)
+* code repository integration (cgit: done, TODO: gitweb, etc...)
-* migration path to v2 without breaking v1 "git fetch" cronjobs
+* migration path to v2 (making it transparent for "git fetch"
+ may not be possible, but "public-inbox-fetch" will handle it)
* imperfect scraper importers for obfuscated list archives
(e.g. obfuscated Mailman stuff, Google Groups, etc...)
-* consider using HTTP::Date instead of Date::Parse, since we need the
- former is capable of parsing RFC822-ish dates, used by Plack, and
- the latter is missing from OpenBSD and maybe other distros.
-
* improve performance and avoid head-of-line blocking on slow storage
+ (done for most git blob retrievals, Xapian needs work)
+
+* allow optional use of separate Xapian worker process to implement
+ timeouts and avoid head-of-line blocking problems. Consider
+ just-ahead-of-time builds to take advantage of custom date parsers
+ (approxidate) and other features not available to Perl bindings.
+
+* integrate git approxidate parsing into Xapian w/o spawning git
+
+* HTTP(S) search API (likely JMAP, but GraphQL could be an option)
+ It should support git-specific prefixes (dfpre:, dfpost:, dfn:, etc)
+ as extensions. If JMAP, it should have HTTP(S) analogues to
+ various IMAP extensions.
-* share "git cat-file --batch" processes across inboxes to avoid
- bumping into /proc/sys/fs/pipe-user-pages-* limits
+* scalability to tens/hundreds of thousands of inboxes
+
+ - inotify-based manifest.js.gz updates
+
+ ...
+
+* lei - see %CMD in lib/PublicInbox/LEI.pm
+ (there's a truckload here..)
* make "git cat-file --batch" detect unlinked packfiles so we don't
have to restart processes (very long-term)
-* support searching based on `git-patch-id --stable` to improve
- bidirectional mapping of commits <=> emails
-
* linter to check validity of config file
* linter option and WWW endpoint to graph relationships and flows
- between inboxes, addresses maildirs, coderepos, etc...
+ between inboxes, addresses, Maildirs, coderepos, newsgroups,
+ IMAP mailboxes, etc...
* pygments support - via Python script similar to `git cat-file --batch'
to avoid startup penalty. pygments.rb (Ruby) can be inspiration, too.
* highlighting + linkification for "git format-patch --interdiff" output
-* highlighting + linkification for "git format-patch --range-diff" output
- (requires mirroring of git repos)
+* highlighting for "git format-patch --range-diff" output
+ (linkification is too expensive, as it requires mirroring)
+
+* support UUCP addresses for legacy archives
+
+* support pipelining as an IMAP/NNTP client for -watch + lei
-* parse and allow (semi)automatic-mirroring of "git request-pull" output
- for coderepos
+* expose lei contents via read/write IMAP/JMAP server for personal use
-* configurable diff output for solver-generated blobs
+* git SHA-256 migration/coexistence path
-* figure out how search for messages with multiple Date: headers
- should work (some wacky examples out there...)
+* decode RFC 3676 format=flowed + DelSp properly (see mflow (mblaze), mutt, ...)
