add read_file_to_str_until_eof which is used by read_file_to_str
if the file happens to be a FIFO.
change file_status() to return FN_FILE if st_mode matches S_IFIFO
(on not-windows) so that init_key_from_file() will read from a FIFO.
We already had code on windows to fix our file sizes when we're
reading a file in text mode and its size doesn't match the size from
fstat. But that code was only enabled when _WIN32 was defined, and
Cygwin defines __CYGWIN__ instead.
Fixes bug 6844; bugfix on 0.1.2.7-alpha.
This would be undefined behavior if it happened. (It can't actually
happen as we're using round_to_power_of_2, since we would have to
be trying to allocate exabytes of data.)
While we're at it, fix the behavior of round_to_power_of_2(0),
and document the function better.
Fix for bug 6831.
Our flag voting code needs to handle unrecognized flags, so it stores
them in a 64-bit bitfield. But we never actually checked for too many
flags, so we were potentially doing stuff like U64_LITERAL(1)<<flagnum
with flagnum >= 64. That's undefined behavior.
Fix for bug 6833; bugfix on 0.2.0.1-alpha.
097 hasn't seen a new version since 2007; we can drop support too.
This lets us remove our built-in sha256 implementation, and some
checks for old bugs.
This reverts commit 4aff97cfc7.
We don't actually want to be changing the torrc.sample on stable or
near-stable stuff, since doing so makes pointless busywork for debian
users.
When I removed version_supports_begindir, I accidentally removed the
mechanism we had been using to make a directory cache self-test its
directory port. This caused bug 6815, which caused 6814 (both in
0.2.4.2-alpha).
To fix this bug, I'm replacing the "anonymized_connection" argument to
directory_initiate_command_* with an enumeration to say how indirectly
to connect to a directory server. (I don't want to reinstate the
"version_supports_begindir" argument as "begindir_ok" or anything --
these functions already take too many arguments.)
For safety, I made sure that passing 0 and 1 for 'indirection' gives
the same result as you would have gotten before -- just in case I
missed any 0s or 1s.
