We need to encode here instead of doing escaped(), since fwict
escaped() does not currently handle NUL bytes.
Also, use warn_if_nul_found in more cases to avoid duplication.
Use a table-based lookup to find the right command handler. This
will serve as the basement for several future improvements, as we
improve the API for parsing commands.
This should please coverity, and fix CID 1415721. It didn't
understand that networkstatus_get_param() always returns a value
between its minimum and maximum values.

This should please coverity, and fix CID 1415723. It didn't understand

And fix the documentation on the function: it does produce trailing
"="s as padding.
Also remove all checks for the return value, which were redundant anyway,
because the function never failed.

When we fixed 28614, our answer was "if we failed to load the
consensus on windows and it had a CRLF, retry it." But we logged
the failure at "warn", and we only logged the retry at "info".
Now we log the retry at "notice", with more useful information.
Fixes bug 30004.
Previously we used time(NULL) to set the Expires: header in our HTTP
responses. This made the actual contents of that header untestable,
since the unit tests have no good way to override time(), or to see
what time() was at the exact moment of the call to time() in
dircache.c.
This gave us a race in dir_handle_get/status_vote_next_bandwidth,
where the time() call in dircache.c got one value, and the call in
the tests got another value.
I'm applying our regular solution here: using approx_time() so that
the value stays the same between the code and the test. Since
approx_time() is updated on every event callback, we shouldn't be
losing any accuracy here.
Fixes bug 30001. Bug introduced in fb4a40c32c4a7e5; not in any
released Tor.
When a directory authority is using a bandwidth file to obtain the
bandwidth values that will be included in the next vote, serve this
bandwidth file at /tor/status-vote/next/bandwidth.z.
This is something we should think about harder, but we probably want dormant
mode to be more powerful than padding in case a client has been inactive for a
day or so. After all, there are probably no circuits open at this point and
dormant mode will not allow the client to open more circuits.
Furthermore, padding should not block dormant mode from being activated, since
dormant mode relies on SocksPort activity, and circuit padding does not mess
with that.
The previous commits introduced link_specifier_dup(), which is
implemented using trunnel's opaque interfaces. So we can now
remove hs_desc_link_specifier_dup().
Cleanup after bug 22781.
The previous commits for 23576 confused hs_desc_link_specifier_t
and link_specifier_t. Removing hs_desc_link_specifier_t fixes this
confusion.
Fixes bug 22781; bugfix on 0.3.2.1-alpha.
This patch fixes a crash bug (assertion failure) in the PT subsystem
that could get triggered if the user cancels bootstrap via the UI in
TorBrowser. This would cause Tor to call `managed_proxy_destroy()` which
called `process_free()` after it had called `process_terminate()`. This
leads to a crash when the various process callbacks returns with data
after the `process_t` have been freed using `process_free()`.
We solve this issue by ensuring that everywhere we call
`process_terminate()` we make sure to detach the `managed_proxy_t` from
the `process_t` (by calling `process_set_data(process, NULL)`) and avoid
calling `process_free()` at all in the transports code. Instead we just
call `process_terminate()` and let the process exit callback in
`managed_proxy_exit_callback()` handle the `process_free()` call by
returning true to the process subsystem.

Remove router_update_info_send_unencrypted(), and move its code into the
relevant functions.
Then, re-use an options pointer.
Preparation for testing 29017 and 20918.
Remove some tiny static functions called by router_build_fresh_descriptor(),
and move their code into more relevant functions.
Then, give router_update_{router,extra}info_descriptor_body identical layouts.
Preparation for testing 29017 and 20918.
Make sure that these static functions aren't passed NULL.
If they are, log a BUG() warning, and return an error.
Preparation for testing 29017 and 20918.
Split the body of router_build_fresh_descriptor() into static functions,
by inserting function prologues and epilogues between existing sections.
Write a new body for router_build_fresh_descriptor() that calls the new
static functions.
Initial refactor with no changes to the body of the old
router_build_fresh_descriptor(), except for the split.
Preparation for testing 29017 and 20918.
When ExtraInfoStatistics is 0, stop including bandwidth usage statistics,
GeoIPFile hashes, ServerTransportPlugin lines, and bridge statistics
by country in extra-info documents.
Fixes bug 29018; bugfix on 0.2.4.1-alpha (and earlier versions).
