We add a compression level argument to tor_zlib_new, and use it to
determine how much memory to allocate for the zlib object. We use the
existing level by default, but shift to smaller levels for small
requests when we have been over 3/4 of our memory usage in the past
half-hour.
Closes ticket 11791.
Add unit tests for tor_timegm signed overflow,
tor_timegm and parse_rfc1123_time validity checks,
and correct_tm year clamping.
Unit tests (visible) fixes in bug 13476.
Fix an instance of integer overflow in format_time_interval() when
taking the absolute value of the supplied signed interval value.
Fixes bug 13393.
Create unit tests for format_time_interval().
When a spawned process forks, fails, then exits very quickly, (this
typically occurs when exec fails), there is a race condition between the
SIGCHLD handler updating the process_handle's fields, and checking the
process status in those fields. The update can occur before or after the
spawn tests check the process status.
We check whether the process is running or not running (rather than just
checking if it is running) to avoid this issue.
These wrappers went into place when the default type for our unit
test functions changed from "void fn(void)" to "void fn(void *arg)".
To generate this patch, I did the same hokey-pokey as before with
replacing all operators used as macro arguments, then I ran a
coccinelle script, then I ran perl script to fix up everything that
used legacy_test_helper, then I manually removed the
legacy_test_helper functions, then I ran a final perl script to put
the operators back how they were.

"The NULL pointer warnings on the return value of
tor_addr_to_in6_addr32() are incorrect. But clang can't work this
out itself due to limited analysis depth. To teach the analyser that
the return value is safe to dereference, I applied tor_assert to the
return value."
Patch from teor. Part of 13157.
On a non-blocking pipe fgets sets EAGAIN when it encounters partial lines. No
error is set on full lines or EOF. EOF is reached when the writing end of the
pipe is closed. Partial lines and full lines are both returned by fgets, EOF
results in NULL.
Mention of this behaviour can be found in #1903 and #2045.
Long ago we supported systems where there was no support for
threads, or where the threading library was broken. We shouldn't
have do that any more: on every OS that matters, threads exist, and
the OS supports running threads across multiple CPUs.
This resolves tickets 9495 and 12439. It's a prerequisite to making
our workqueue code work better, since sensible workqueue
implementations don't split across multiple processes.
Try killing a running process; try noticing that a process has
exited without checking its output; verify that waitpid_cb (when
present) is set to NULL when you would expect it to be.
On OpenBSD 5.4, time_t is a 32-bit integer. These instances contain
implicit treatment of long and time_t as comparable types, so explicitly
cast to time_t.
