This fixes a warning in efb8a09f, where Debain Lenny's GCC doesn't get
that
for (i=0; i<3; ++i) {
const char *p;
switch(i) {
case 0:
p="X"; break;
case 1:
p="Y"; break;
case 2:
p="Z"; break;
}
printf("%s\n", p);
}
will never try to print an uninitialezed value.
Found by buildbots. Bug in no released versions of Tor.

Merge the unit tests; I added some when I did this branch against
0.2.2, and then the test format changed and master added more tests.
The parent of "/foo" is "/"; and "/" is its own parent.
This would cause Tor to fail if you tried to have a PF_UNIX control
socket in the root directory. That would be a stupid thing to do
for other reasons, but there's no reason to fail like _this_.
Bug found by Esteban Manchado Velázquez. Fix for bug 5089; bugfix on
Tor 0.2.2.26-beta. Unit test included.
(When the correct answer is given in terms of seconds since the
epoch, it's hard to be sure that it really is the right answer
just by reading the code.)
* It seems parse_http_time wasn't parsing correctly any date with commas (RFCs
1123 and 850). Fix that.
* It seems parse_http_time was reporting the wrong month (they start at 0, not
1). Fix that.
* Add some tests for parse_http_time, covering all three formats.
The underlying strtoX functions handle overflow by saturating and
setting errno to ERANGE. If the min/max arguments to the
tor_parse_* functions are equal to the minimum/maximum of the
underlying type, then with the old approach, we wouldn't treat a
too-large value as genuinely broken.
Found this while looking at bug 5786; bugfix on 19da1f36 (in Tor
0.0.9), which introduced these functions.
They boil down to:
- MS_WINDOWS is dead and replaced with _WIN32, but we let a few
instances creep in when we merged Esteban's tests.
- Capitalizing windows header names confuses mingw.
- #ifdef 0 ain't C.
- One unit test wasn't compiled on windows, but was being listed
anyway.
- One unit test was checking for the wrong value.
Gisle Vanem found and fixed the latter 3 issues.

Nick here. I tweaked this patch a little to make it apply cleanly to
master, to extract some common code into a function, and to replace
snprintf with tor_snprintf.

Coverity doesn't like the fact that we were storing the value of
parse_config_line_from_str() but not checking it in a couple of
cases.
Fixes CID 505 and 506.
* This assertion fails when executing the whole suite, but not when executing
this test by itself
* Ideally I'd prefer starting with a guaranteed empty directory, but it's not
very important in this case as non-existence of other paths is being checked
explicitly
* Add several failing tests (embedded in an "#if 0" block) for behaviour that
doesn't match strtok_r
* Add another, passing, more interesting test
* Use test_eq_ptr(NULL, ...) instead of test_assert(NULL == ...)
* Add many new test cases, tweak/improve existing ones, reorganize them a bit
* Switch the parameters in all test_eq calls so the expected value is the first
* Change all the "r = tor_sscanf(...);\ntest_eq(1, r)" to the more compact
"test_eq(1, tor_sscanf(...))". It may be a tiny bit harder to find the
tor_sscanf calls (it's the long lines anyway), but it saves a lot of lines,
which should help readability.
* Switch some test_eq parameters so the expected is always the first parameter
* Drop some manual checks of compressed format magic numbers (they're pointless
and they make the unit tests less readable and more fragile, considering
we're already indirectly checking those magic numbers via the
detect_compression_method function)
* Add a couple of extra assertions
* The test currently fails, but it's commented out (with an "#if 0")
* As a broken octal actually gives a parse error, it seems fair that this
fails, too
This commit is completely mechanical; I used this perl script to make it:
#!/usr/bin/perl -w -i.bak -p
if (/^\s*\#/) {
s/MS_WINDOWS/_WIN32/g;
s/\bWIN32\b/_WIN32/g;
}
test_util_spawn_background_ok() hardcoded the expected value
for ENOENT to 2. This isn't portable as error numbers are
platform specific, and particularly the hurd has ENOENT at
0x40000002.
Construct expected string at runtime, using the correct value
for ENOENT (closes: #4733).
Let's *not* expose more cross-platform-compatibility structures, or
expect code to use them right.
Also, don't fclose() stdout_handle and stdin_handle until we do
tor_process_handle_destroy, or we risk a double-fclose.
On some platforms, with non-blocking IO, on EOF you first
get EAGAIN, and then on the second read you get zero bytes
and EOF is set. However on others, the EOF flag is set as
soon as the last byte is read. This patch fixes the test
case in the latter scenario.
After a stream reached eof, we fclose it, but then
test_util_spawn_background_partial_read() reads from it again, which causes
an error and thus another fclose(). Some platforms are fine with this, others
(e.g. debian-sid-i386) trigger a double-free() error. The actual code used by
Tor (log_from_pipe() and tor_check_port_forwarding()) handle this case
correctly.
Mainly used for testing reading from subprocesses. To be more generic
we now pass in a pointer to a process_handle_t rather than a Windows-
specific HANDLE.
Conventionally in Tor, structs are returned as pointers, so change
tor_spawn_background() to return the process handle in a pointer rather
than as return value.
- pid, stdout/stderr_pipe now encapsulated in process_handle
- read_all replaced by tor_read_all_from_process_stdin/stderr
- waitpid replaced by tor_get_exit_code
Untested on *nix
