The two options are mutually exclusive, since otherwise an entry
like "Foo" would be ambiguous. We want to have the ability to treat
entries like this as keys, though, since some controller commands
interpret them as flags.
(This should be all of the command that work nicely with positional
arguments only.)
Some of these commands should probably treat extra arguments as
incorrect, but for now I'm trying to be careful not to break
any existing users.
The first line break in particular was mishandled: it was discarded
if no arguments came before it, which made it impossible to
distinguish arguments from the first line of the body.
To solve this, we need to allocate a copy of the command rather than
using NUL to separate it, since we might have "COMMAND\n" as our input.
Fixes ticket 29984.
There _is_ an underlying logic to these commands, but it isn't
wholly uniform, given years of tweaks and changes. Fortunately I
think there is a superset that will work.
This commit adds a parser for some of the most basic cases -- the
ones currently handled by getargs_helper() and some of the
object-taking ones. Soon will come initial tests; then I'll start using
the parser.
After that, I'll expand the parser to handle the other cases that come
up in the controller protocol.
We have checks in various places in mainlook.c to make sure that
events are initialized before we invoke any periodic_foo() functions
on them. But now that each subsystem will own its own periodic
events, it will be cleaner if we don't assume that they are all
setup or not.
The end goal here is to move the periodic callback to their
respective modules, so that mainloop.c doesn't have to include so
many other things.
This patch doesn't actually move any of the callbacks out of
mainloop.c yet.
In this patch we lower the log level of the failures for the three calls
to unlink() in networkstatus_set_current_consensus(). These errors might
trigger on Windows because the memory mapped consensus file keeps the
file in open state even after we have close()'d it. Windows will then
error on the unlink() call with a "Permission denied" error.
The consequences of ignoring these errors is that we leave an unused
file around on the file-system, which is an easier way to fix this
problem right now than refactoring networkstatus_set_current_consensus().

When releasing OpenSSL patch-level maintenance updates,
we do not want to rebuild binaries using it.
And since they guarantee ABI stability, we do not have to.
Without this patch, warning messages were produced
that confused users:

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.
The smartlist functions take great care to reset unused pointers inside
the smartlist memory to NULL.
The function smartlist_remove_keeporder does not clear memory in such
way when elements have been removed. Therefore call memset after the
for-loop that removes elements. If no element is removed, it is
effectively a no-op.

The smartlist code takes great care to set all unused pointers inside
the smartlist memory to NULL. Check if this is also the case after
modifying the smartlist multiple times.

Previously, our use of abort() would break anywhere that we didn't
include stdlib.h. This was especially troublesome in case where
tor_assert_nonfatal() was used with ALL_BUGS_ARE_FATAL, since that
one seldom gets tested.
As an alternative, we could have just made this header include
stdlib.h. But that seems bloaty.
Fixes bug 30189; bugfix on 0.3.4.1-alpha.
