r2500 | des | 2008-02-17 11:02:07 +0100 (Sun, 17 Feb 2008) | 2 lines
Fix assert in thread_close() for fd == nthreads == 0.
........
r2501 | des | 2008-02-17 23:37:41 +0100 (Sun, 17 Feb 2008) | 16 lines
A number of changes made while trying to reproduce #176:
- modify thread_log() to take an "errcode" argument (typically errno) so
we don't have to sprinkle the code with strerror() calls.
- read_line() and read_block() would sometimes unnecessarily log an error
for a short read; let the caller decide whether a short read is
acceptable.
- reorder the if / else if / else blocks in receive_response() so the
logic is easier to follow.
- remove test code which we no longer need.
- fix some style issues; there are still a couple of long lines, though.
........
r2502 | des | 2008-02-18 00:29:24 +0100 (Mon, 18 Feb 2008) | 3 lines
Add a log message for short reads in the content-length case.
Also, clean up some variable names and declarations.
