Changes in version 0.2.1.1-alpha - 2008-??-??
o Memory fixes and improvements:
- Add a malloc_good_size implementation to OpenBSD_malloc_linux.c,
to avoid unused RAM in buffer chunks and memory pools.
- Speed up parsing and cut down on memory fragmentation by using
stack-style allocations for parsing directory objects. Previously,
this accounted for over 40% of allocations from within Tor's code
on a typical directory cache.
- Use a Bloom filter rather than a digest-based set to track which
descriptors we need to keep around when we're cleaning out old
router descriptors. This speeds up the computation significantly,
and may reduce fragmentation.
- Reduce the default smartlist size from 32 to 16; it turns out that
most smartlists hold around 8-12 elements tops.
- Make dumpstats() log the fullness and size of openssl-internal
buffers.
- If the user has applied the experimental SSL_MODE_RELEASE_BUFFERS
patch to their OpenSSL, turn it on to save memory on servers. This
patch will (with any luck) get included in a mainline distribution
before too long.
o Minor bugfixes:
- Stop giving double-close warn when we reject an address for
client DNS.
- Make relay cells written on a connection count as non-padding when
tracking how long a connection has been in use. Bugfix on
0.2.0.1-alpha. Spotted by lodger.
- Reduce the default smartlist size from 32 to 16; it turns out that
most smartlists hold around 8-12 elements tops.
- When we choose to abandon a new entry guard because we think our
older ones might be better, close any circuits pending on that
new entry guard connection. Bugfix on 0.1.2.8-beta; found by lodger.

domains. For example, this allows one to log all notices, warnings,
or errors, plus all memory management messages of level debug or
higher, with: Log [MM] debug-err [*] notice-err file /var/log/tor.
- Add a malloc_good_size implementation to OpenBSD_malloc_linux.c,
to avoid unused RAM in buffer chunks and memory pools.
- Add a couple of extra warnings to --enable-gcc-warnings for GCC 4.3,
and stop using a warning that had become unfixably verbose under
GCC 4.3.

bug got fixed in late 2006. Our new behavior is to call RAND_poll()
at startup, and to call RAND_poll() when we reseed later only if
we have a non-buggy OpenSSL version.
- Speed up parsing and cut down on memory fragmentation by using
stack-style allocations for parsing directory objects. Previously,
this accounted for over 40% of allocations from within Tor's code
on a typical directory cache.
- Lots of new unit tests.
- New --hush command-line option similar to --quiet. While --quiet
disables all logging to the console on startup, --hush limits the
output to messages of warning and error severity.
- Use a Bloom filter rather than a digest-based set to track which
descriptors we need to keep around when we're cleaning out old
router descriptors. This speeds up the computation significantly,
and may reduce fragmentation.
- Make dumpstats() log the fullness and size of openssl-internal
buffers.
- Servers support a new URL scheme for consensus downloads that
allows the client to specify which authorities are trusted.
The server then only sends the consensus if the client will trust
it. Otherwise a 404 error is sent back. Clients can use this
new scheme when the server supports it. Implements proposal 134;
disabled for now though.
- If the user has applied the experimental SSL_MODE_RELEASE_BUFFERS
patch to their OpenSSL, turn it on to save memory on servers. This
patch will (with any luck) get included in a mainline distribution
before too long.
- New configure/torrc options (--enable-geoip-stats,
DirRecordUsageByCountry) to record how many IPs we've served
directory info to in each country code, how many status documents
