Remember the valid-until time of the most recent consensus that listed
a router, and (if we are a cache) never delete the routerdesc until
that conensus is expired. This is way easier than retaining multiple
consensuses. (Of course, the info isn't retained across restarts,
but that only affects a few caches at a time.)
svn:r12041
Make unverified-consensus get removed when it is accepted or rejected. Make a new get_datadir_fname*() set of functions to eliminate the common code of "get the options, get the datadir, append some stuff".
svn:r12000
Implement v3 networkstatus client code. Remove v2 networkstatus client code, except as needed for caches to fetch and serve v2 networkstatues and the routers they list.
svn:r11957
Fix a bunch of XXX020s: treat some 403s as INFO severity; remove some dead code; share the retry path for consensus routerdescs that are also listed in the v2 networkstatus; check even more aspects of votes when parsing them.
svn:r11871
Retry consensus and certificate downloads properly. Do not fail when there are no certificates to download. Do not download certificates we already have when retrying.
svn:r11841
Use download_status_t for v2 networkstatuses and certs as well as for routers. Make functions to manipulate it. Next steps: use it for consensus networkstatuses, and get consensus download rescheduling working.
svn:r11800
Refactor out about a third of routerlist.c into a new networkstatus.c. I\m not sure that I got everything that needed to move, but so far so good.
svn:r11791
Make router_digest_is_trusted_dir able to check for type. When looking for a V3 directory, only assume that the V3 authorities and caches have it: previous code assumed that all authorities had it.
svn:r11789
Add a bunch of function documentation; clean up a little code; fix some XXXXs; tag the nonsensical EXTRAINFO_PURPOSE_GENERAL as nonsesnse; note another bit of "do not cache special routers" code to nuke.
svn:r11761
Use descriptor annotations to record the source, download t time, and purpose of every descriptor we add to the store. The remaining to-do item is to stop setting do_not_cache on bridges.
svn:r11680
Remove annotated_desc_store store (which we never used). Instead, shift name of router store to cached-descriptors, but initialize it from cached-routers as needed
svn:r11678
Fix a stupid logic error in authority_cert_get_by_sk_digest: the presence of an authority lacking a v3 cert does not mean that subsequent authorities lack them too.
svn:r11668
More annotated-store work: handle annotations in lists correctly. Add ability to prepend annotations to a routerdesc (and to every rtouredesc in a list), while verifying that the routerdesc is not already annotated.
svn:r11665
Backend for descriptor annotations: parse annotations as keywords; only allow them to appear in the cache; do not serve them as part of the descriptor if we are a dirserver. Still need mechanism to set annotations. Still need to rename cache file.
svn:r11654
users configure that and specify a bridge with an identity
fingerprint, now they will lookup the bridge descriptor at the
default bridge authority via a one-hop tunnel, but once circuits
are established they will switch to a three-hop tunnel for later
connections to the bridge authority.
svn:r11550
Refactor store_stats_t to hold a pointer to the proper mmap, and turn it into a full-fledged type. This sets stuff up nicely for adding a separate "annotated" store. Add some XXXX NM items that need to be fixed when annotated stores exist
svn:r11338
More directory voting code. Now, if everything works, and I haven't forgotten anything, it is possible to set up some v3 authorities and start voting. Of course, I have probably forgotten something, and there are probably bugs in there somewhere too.
svn:r10976
Better certificate manipulations: extract certificates from incoming votes, forget ones that are very old, and remember to store them on disk.
svn:r10954
Fix router_choose_by_bandwidth to no longer be biases by floating-point roundoff issues. This runs through the list of routers yet another time, and uses an additional bitfield, but this should be okay: the function did not appear in profiles before, and shouldnt start appearing now.
svn:r10939
(we always picked one router past the one we wanted!) and could
conceivably read past the end of the smartlist too.
Nick, I don't know what gcc 4.2 was worried about, but we need
to find a better fix than this. :)
svn:r10901
Fix a potential crash bug when we load many server descriptors at
once and some of them make others of them obsolete. Fixes bug
458. [Bugfix on 0.1.2.x]
svn:r10832
Patch from lodger: avoid roundoff-error-induced crash bugs when picking routers by bandwidth.
Also, remove listed backports for 0.1.2.x; that list is now in TODO.012
svn:r10812
the old router's index in the routerlist, can be gotten from the
old routerinfo itself anyway, and make_old always was true.
(There only is one caller of routerlist_replace())
svn:r10753
- Only listen to responses for "authority" fetches if we're configured
to use Bridges. Otherwise it's safe (and maybe smarter) to silently
discard them like we used to.
- React faster to download networkstatuses after the first bridge
descriptor arrives.
- Don't do dir fetches before we have any bridges, even when our
dirport is open.
svn:r10604
- demand options->Bridges and options->TunnelDirConns if
options->UseBridges is set.
- after directory fetches, accept descriptors that aren't referenced by
our networkstatuses, *if* they're for a configured bridge.
- delay directory fetching until we have at least one bridge descriptor.
- learn how to build a one-hop circuit when we have neither routerinfo
nor routerstatus for our destination.
- teach directory connections how to pick a bridge as the destination
directory when doing non-anonymous fetches.
- tolerate directory commands for which the dir_port is 0.
- remember descriptors when the requested_resource was "authority",
rather than just ignoring them.
- put bridges on our entry_guards list once we have a descriptor for them.
When UseBridges is set, only pick entry guards that are bridges. Else
vice versa.
