Initial version of code to stop using socket pairs for linked connections. Superficially, it seems to work, but it probably needs a lot more testing and attention.
svn:r9995
Track the number of connection_t separately from the number of open sockets. It is already possible to have connections that do not count: resolving conns, for one. Once we move from socketpairs to linked conns, and once we do dns proxying, there will be lots of such connections.
svn:r9994
Fix a bug in displaying memory pool usage. Also dump cell allocation, and track padded_cell_ts as they are allocated and freed, to make sure we are not leaking cells.
svn:r9992
More proposal-104 stuff: add most of the code for authorities to accept and serve extra-info documents. The back-end to store the things is missing.
svn:r9971
Now that the directory parser checks for missing items, the rest of the code can just assert that they are there, rather than checking a second time.
svn:r9966
Refactor router/directory parsing backend: use a separate token table for everything that we parse, and enforce the correct count of each item.
svn:r9965
Initial code to parse extra-info documents as described in proposal 104. This is making me realize that the parsing code in routerparse.c is a little daft.
svn:r9963
More autoconf hacking: use same machinery to find zlib as for openssl and libevent. Have unified library finder include setup for --with variable. Start trying to suggest to the user what packages they should install if finding the library fails.
svn:r9945
Add code to shrink the cell memory pool by discarding empty chunks that have been empty for the last 60 seconds. Also, instead of having test.c duplicate declarations for exposed functions, put them inside #ifdef foo_PRIVATE blocks in the headers. This prevents bugs where test.c gets out of sync.
svn:r9944
Yet another attempted Bug 411 fix: Under some circumstances, a circuit can have cells without being active. The likeliest is that it has been unlinked from all connections in preparation for closing. Therefore, stop enforcing this non-invariant.
svn:r9936
Split type of "packed cell" from "parsed cell"; pack cells before queueing them on circuits. This will help us avoid dumb errors when we confuse the two types.
svn:r9935
Simplify dns_resolve: use a helper function so that we handle the error/answer/pending cases uniformly in dns_resolve, and everything else in dns_resolve_impl.
svn:r9932
A surprisingly simple patch to stop reading on edge connections when their circuits get too full, and start again when they empty out. This lets us remove the logic to block begin_dir conns when the corresponding or conns get full: it was already broken by cell queues anyway.
svn:r9905
Initial version of circuit-based cell queues. Instead of hammering or_conns with piles of cells, queue cells on their corresponding circuits, and append them to the or_conn as needed. This seems to work so far, but needs a bit more work. This will break the memory-use-limitation patch for begin_dir conns: the solution will be a fun but fiddly.
