Here we make it clear we're only looking at listable variable names,
not at whether the variables themselves are gettable.
Also, remove an extraneous h.
(This commit is not a fixup, because of rebase conflicts.)
Since the flags are now stored with compatible numbering, we can
just OR them together and see whether the flag we want is in the
result.
(Net code removal!)
Using a bitfield here will enable us to unify the var_type_def_t flags
with the config_var_t flags.
(This commit does not yet do that unification, and does not yet
rename or refactor any flags. It only changes booleans into bits.)
Previously they checked the individual flags inside var_type_def_t;
now they call the appropriate var_type_is_*() functions.
(These functions will be removed entirely by the end of this branch.)
We had though to make all obsolete and invisible variables
ungettable, so that GETCONF would reject them. But it turns out
that this isn't the current behavior of GETCONF with those
variables. So for now, I'm leaving the current behavior unchanged.
(See ticket 31647 for a proposal to change the behavior.)
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.
Fixes part of bug 31687; bugfix on 0.2.3.4-alpha when this code was
added.
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.
Fixes part of 31687. I'm calling this a bugfux on 31687, when we
started suppressing these warnings on Windows.
We have code in microdescs_parse_from_string() to record the digests
of microdescriptors that we could not parse. But right now, that
code looks at the md->digest field, which is a bit inelegant, and
will stand in the way of sensible refactoring.
Instead, use a local variable to hold the digest.
This test makes sure that we parse ed25519 identities to get the
correct data from them. It also tests:
* That a microdescriptor may not have two ed25519 identities.
* That a microdescriptor may not have an ed25519 identity that is
not a valid base64-encoded ed25519 key.
* That a microdescriptor may have an unrecognized identity type.
It will help test the refactoring of ticket31675.
These levels get out of date really easily: we'll implement a level
dump command in tor in 31614.
They also cause conflicts and inconsistencies when merging forward
level changes.
Part of 31615.
