[issue30576] http.server should support HTTP compression (gzip)

[Pierre Quentel]

Pierre Quentel  added the comment:

On the Github site Raymond Hettinger is mentioned as the reviewer. I don't know 
how to contact him, can anyone ask him if he can review the PR on time for 
inclusion in Python 3.7 ?

I understand that it's difficult to find time for this and that there are many 
pending PRs ; I can't judge if this one is more or less important than the 
others, but the issue has been discussed for a few months now, the code has 
been improved after many iterations, so hopefully it should not be too far from 
approval.

[issue1104] msilib.SummaryInfo.GetProperty() truncates the string by one character

[Tzu-ping Chung]

Tzu-ping Chung  added the comment:

I have created a PR #4517 from the patch. Would it be better to track the 
malloc problem in a new issue?

As for why this never caused any problems… msilib is pretty standalone, and not 
one of the most used modules. It is also pretty trivial to roll your own 
solution with ctypes (or any FFI library), which is what I did when I hit this 
bug.

[issue32119] test_notify_all() of test_multiprocessing_forkserver failed on Python on x86 Tiger 3.6 with "ValueError: cannot convert float NaN to integer"

[STINNER Victor]

STINNER Victor  added the comment:

Interesting info about NaN on Intel x86:

https://stackoverflow.com/questions/14021763/c-multiplication-or-addition-floats-results-nan

"The multiplication is being performed in the x87 registers, and a 
floating-point stack overflow has occurred due to (possibly unrelated) earlier 
operations in your program's execution. When the processor is in this failure 
state, all computations performed on the x87 registers produce NaN results."

For FreeBSD, Python main() starts with:

/* 754 requires that FP exceptions run in "no stop" mode by default,
 * and until C vendors implement C99's ways to control FP exceptions,
 * Python requires non-stop mode.  Alas, some platforms enable FP
 * exceptions by default.  Here we disable them.

[issue32119] test_notify_all() of test_multiprocessing_forkserver failed on Python on x86 Tiger 3.6 with "ValueError: cannot convert float NaN to integer"

[STINNER Victor]

STINNER Victor  added the comment:

"ValueError: cannot convert float NaN to integer": this error occurred on 
int(float), where the float comes from os.stat()

File "", line 762, in get_code

Lib/importlib/_bootstrap_external.py:

def get_code(self, fullname):
...
st = self.path_stats(source_path)
...
source_mtime = int(st['mtime']) <~~ HERE
...

def path_stats(self, path):
st = _path_stat(path)
return {'mtime': st.st_mtime, 'size': st.st_size}

def _path_stat(path):
return _os.stat(path)

=> The float NaN comes from os.stat().st_mtime.


Implementation of os.stat().st_mtime in Modules/posixmodule.c:

static PyObject*
_pystat_fromstructstat(STRUCT_STAT *st)
{
...
#if defined(HAVE_STAT_TV_NSEC)
ansec = st->st_atim.tv_nsec;
mnsec = st->st_mtim.tv_nsec;
cnsec = st->st_ctim.tv_nsec;
#elif defined(HAVE_STAT_TV_NSEC2)
ansec = st->st_atimespec.tv_nsec;
mnsec = st->st_mtimespec.tv_nsec;
cnsec = st->st_ctimespec.tv_nsec;
#elif defined(HAVE_STAT_NSEC)
ansec = st->st_atime_nsec;
mnsec = st->st_mtime_nsec;
cnsec = st->st_ctime_nsec;
#else
ansec = mnsec = cnsec = 0;
#endif
fill_time(v, 7, st->st_atime, ansec);
fill_time(v, 8, st->st_mtime, mnsec);
fill_time(v, 9, st->st_ctime, cnsec);
...
}

static void
fill_time(PyObject *v, int index, time_t sec, unsigned long nsec)
{
...
float_s = PyFloat_FromDouble(sec + 1e-9*nsec);  <~~ HERE
...
PyStructSequence_SET_ITEM(v, index+3, float_s);
...
}


Extract of the ./configure script output:

checking for tv_nsec in struct stat... no
checking for tv_nsec2 in struct stat... yes

=> configure defines HAVE_STAT_TV_NSEC2


We need sec and nsec values from fill_time() to debug this issue.
