When tearing down all periodic events during shutdown, disable them first so
their enable flag is updated.
This allows the tor_api.h to relaunch tor properly after a clean shutdown.

Running doxygen with latex gave us all manner of unicode issues,
slowed down the "make doxygen" target by a lot, and added several
latex dependencies... all to produce a 4000-page reference manual
which is probably not what anybody wanted.

Code adapted from Rob's proposed patch in #30344.
Also add a comment in connection_mark_for_close_internal_() on why we should
not be adding extra code there without a very good reason.
When considering introduction point of a service's descriptor, do not remove
an intro point that has an established or pending circuit.
Fixes#31652
Signed-off-by: David Goulet <dgoulet@torproject.org>
When encoding introduction points, we were not checking if that intro points
had an established circuit.
When botting up, the service will pick, by default, 3 + 2 intro points and the
first 3 that establish, we use them and upload the descriptor.
However, the intro point is removed from the service descriptor list only when
the circuit has opened and we see that we have already enough intro points, it
is then removed.
But it is possible that the service establishes 3 intro points successfully
before the other(s) have even opened yet.
This lead to the service encoding extra intro points in the descriptor even
though the circuit is not opened or might never establish (#31561).

These tests all invoke the hostname resolver in one way or another,
and therefore potentially block if our DNS server is missing,
absent, or extremely slow. Closes ticket 31841.
Our minimum version is now 0.2.9.5-alpha. Series 0.3.0, 0.3.1,
0.3.2, 0.3.3, and 0.3.4 are now rejected.
Also, extract this version-checking code into a new function, so we
can test it.
Closes ticket 31549.
Also reject 0.3.5.0 through 0.3.5.6-rc as unstable.
When pkg-config is not installed, or a library that depends on
pkg-config is not found, tell the user what to do to fix the
problem.
Fixes bug 31922; bugfix on 0.3.1.1-alpha.
The documentation for this function says that the smartlist can
contain NULLs, but the code only handled NULLs if they were at the
start of the list.
We didn't notice this for a long time, because when Tor is run
normally, the sequence of msg_id_t is densely packed, and so this
list (mapping msg_id_t to channel_id_t) contains no NULL elements.
We could only run into this bug:
* when Tor was running in embedded mode, and starting more than once.
* when Tor ran first with more pubsub messages enabled, and then
later with fewer.
* When the second run (the one with fewer enabled pubsub messages)
had at least some messages enabled, and those messages were not
the ones with numerically highest msg_id_t values.

Merge master's RUST_VERSION="nightly" into the macOS Rust job
from bug31859_041.
Drop master's RUST_VERSION="beta", because we only have two
Rust jobs now.
Since Travis macOS has IPv6 support (and Travis Linux does not), chutney
will now run its IPv6 networks as part of Travis CI.
But since chutney is slow, don't wait for the macOS chutney to finish.
(Travis have fixed the duplicate notification bug in fast_finish. So we
can use fast_finish and allow_failure to finish early. Unfortunately,
allow_failure also means we ignore failures in macOS chutney.)
Also make sure that we have:
* a compile on each platform, with each compiler,
* a check on each platform, and
* a check on each compiler.
Finally, sort builds: allow fail last, macOS first, slowest first.
Closes ticket 30860.
Closes ticket 31859 for 0.2.9.
This test failure happened due to a signed/unsigned integer
comparison.
This bug occurred on SunOS, it may also occur on other systems that
use signed char as the default. (And cast 1-byte integer constants
to an unsigned integer.)

When processing a %included folder, a bug caused the pointer to
the last element of the options list to be set to NULL when
processing a file with only comments or whitepace. This could
cause options from other files on the same folder to be
discarded depending on the lines after the affected %include.
This warning would previously be given every time we tried to open a
connection to a foo.exit address, which could potentially be used to
flood the logs. Now, we don't allow this warning to appear more
than once every 15 minutes.
Fixes bug 31466; bugfix on 0.2.2.1-alpha, when .exit was first
deprecated.
We want to forbid this pattern since, unlike the other log_*()
macros, log_debug() conditionally evaluates its arguments only if
debug-level logging is enabled. Thus, a call to
log_debug("%d", x++);
will only increment x if debugging logs are enabled, which is
probably not what the programmer intended.
One bug caused by this pattern was #30628.
This script detects log_debug( ) calls with any of E++, E--, ++E,
or --E in their arguments, where E is an arbitrary expression.
Closes ticket 30743.
Our dimap code asserts if you try to add the same key twice; this
can't happen if everything is running smoothly, but it's possible if
you try to start a relay where secret_onion_key_ntor is the same as
secret_onion_key_ntor.old.
Fixes bug 30916; bugfix on 0.2.4.8-alpha when ntor keys were
introduced.
We previously used tor_fragile_assert() to declare that this case
could not happen: VERSIONS cells are always supposed to be
variable-sized, right?
This is incorrect, though. On a v1 link protocol connection, all
cells are fixed-sized. There aren't supposed to be any VERSIONS
cells with this version of the protocol, but apparently, somebody
was messing up. (The v1 link protocol is obsolete, so probably the
implementer responsible didn't mean to be using it.)
Fixes bug 31107. Bugfix on 0.2.4.4-alpha, when we introduced a
tor_fragile_assert() for this case.
These errors can occur if we are built on a system with support for
madvise(MADV_NOFORK) but then we are run on a system whose kernel
does not support that flag.
If the error is something that we don't tolerate at all, we now log
it before crashing.
Fixes bug 31696. I am calling this a bugfix on 0.4.1.1-alpha, where
we actually started using the map_anon code.
This is similar to, but not the same as, the fix for #31570.
Our code assumes that when we're configured to get IPv6 addresses
out of a TRANS_PF transparent proxy connection, we actually will.
But we didn't check that, and so FreeBSD started warning us about a
potential NULL pointer dereference.

We used to do this on Windows only, but it appears to affect
multiple platforms when building with certain versions of GCC, and a
common pattern for defining the floating-point classifier functions.

started suppressing these warnings on Windows.
Fix levels for subsystems that depend on log/err
* winprocess (security) doesn't use err:

* init err after winprocess
* move wallclock so it's still after err
* network and time depend on log:
* make sure that network and time can use logging.
* init network and time after log
Add comments explaining the module init order.

When tor is missing descriptors for some primary entry guards, make the
log message less alarming. It's normal for descriptors to expire, as long

tor-github/pr/1283, with the following changes:
* cherry-pick the merge commit in 1283 on top of...
* tor-github/pr/1174, but with the last commit re-worded to remove
the fixup, because fixups break our push rules.
This is an "ours" merge, except for the bugfix version change in
changes/bug30649.
When we parse a CLEAR line (e.g., "/OrPort" or /OrPort blah blah"),
we always suppress the value, even if one exists. That means that
the block of code was meant to handle CLEAR lines didn't actually do
anything, since we previously handled them the same way as with
other empty values.

Some platforms (macOS, maybe others?) can swallow the last write before an
abort. This issue is probably caused by a race condition between write
buffer cache flushing, and process termination. So we write an extra
newline, to make sure that the message always gets through.

Add a TOR_PUSH_SAME and -s argument to git-push-all.sh to change this
default.
Part of 31314.
TOR_GIT_PUSH provides the git push command and default arguments.
Also fix handling of git-push-all.sh script arguments and arguments that
are passed through to $TOR_GIT_PUSH, using a "--" argument as a separator.
Fix on 29879.
Add a -t <test-branch-prefix> argument to git-merge-forward.sh and
git-push-all.sh, which makes these scripts create, merge forward, and
push test branches.
Add a -r <remote-name> argument to git-push-all.sh, so the script can
push test branches to a personal remote.

Rewrite format_node_description() and router_get_verbose_nickname() to

The #[global_allocator] attribute is not available in versions prior to
1.28.0, the default-linker-libraries feature requires rust 1.31.0.
Adapt the CI to prevent accidental increases in Rust version by testing

The pre-push hook already calls the pre-commit hook, which calls
practracker.
Also update the script comments to avoid similar issues in future.

If unsigned int is 32-bits long, then our old code would give a
wrong result with any log domain whose mask was >= (1<<32).
Fortunately, there are no such log domains right now: the domain
mask is only 64 bits long to accommodate some flags.
