That sounds a lot like Snakebite (www.snakebite.org), which is still...
uhhh, a work in progress ;-)  We've run into an issue recently that's
thwarted progress, but that'll hopefully be resolved in the next couple
of weeks.  And then... full steam ahead!

Actually, for those that are interested, here's a copy of the
presentation I gave at the Testing in Python session at PyCon a few
months ago:

(Office 2007-2010)

(Office 97-2003)

If anything, it'll shed some light on all the unforeseen issues we've
been running into since the project's inception.  The presentation is a
little out of date -- I spent three months earlier this year on the
network and it's definitely in the most respectable state it's been in
yet.  Coupla' photos for those that are interested:

[Python-Dev] Python on Windows with CoApp

2010-05-12 Thread Trent Nelson

Howdy folks,

Quick e-mail at 34,000ft (aren't wifi-enabled flights great?) to mention 
a new initiative that's been started by Microsoft called CoApp (Common 
Opensource Application Publishing Platform).  The aim is simple: make 
open source software rock on Windows ;-)


It's probably easiest to think of it as a 
Microsoft-endorsed-but-community-run open source distribution for 
Windows, akin to all the various package managers for Linux 
distributions and ports/packages for the *BSDs.  There are specific user 
and developer experiences we'll be addressing -- like making it easy to 
install and use open source software, or use it within your own project 
(open source or not).


CoApp will affect Python in one of two ways.  Once there's a clear-cut 
specification for open source projects to follow, Python can either 
decide to follow it, or not.  The same applies to all open source 
packages, actually.  For those that follow it, great!  If not, no 
problem -- the plan is to shallow-fork such projects via launchpad and 
the CoApp community will take responsibility for getting releases of 
open source projects into CoApp shape.


It's in its infancy at the moment -- it took the chap (Garrett Serack) 
who's spearheading it at Microsoft about six months to get it all signed 
off by the lawyers and platform/server VPs.


So, for those of you out there who are Windows-inclined, now's a perfect 
time to get involved to help shape the direction of CoApp going forward.


The website/wiki is http://coapp.org/ and the launchpad project site is 
http://launchpad.net/coapp (which is where the mailing list is hosted).


We're actually having a 'CoApp Development Summit' tomorrow and Friday 
in Seattle (that Microsoft's graciously sponsored).  The event will be 
accessible via Live Meeting for those that are interested: 
http://coapp.org/Project_Planning/CoApp_Design_and_Development_Summit


Regards,

Trent.

Perhaps a little too early, python-dev@ won't know anything about
Snakebite yet as I haven't publicly announced it there ;-)  Watch

FWIW, though, we're planning for Snakebite to be *very* involved

[Python-Dev] Python 2.4, VS 2005 & Profile Guided Optmization

2006-07-23 Thread Trent Nelson
Hi,

Has anyone else built Python with Visual Studio 2005 and played around
with Profile Guided Optimization?  I had to build Python from source w/
VS 2005 as I had a few .pyd's built with VS 2005 that I wanted to load;
I ended up playing around with Profile Guided Optimization, running
``python.exe pystones.py'' to collect call-graph data after
python.exe/Python24.dll had been instrumented, then recompiling with the
optimizations fed back in.  

Results were interesting, an average speedup of around 33% was
noticeable:

ActiveState 2.4.3 python.exe:

C:\Python24>python.exe Lib\test\pystone.py
Pystone(1.1) time for 5 passes = 0.980119 This machine
benchmarks at
51014.2 pystones/second

The python compiled from branches/release24-maint with VS 2005 + profile
guided optimization:

C:\Python24>python.exe Lib\test\pystone.py
Pystone(1.1) time for 5 passes = 0.73261 This machine benchmarks
at
68249.2 pystones/second

Is there any motivation in the Win32 Python dev camp to switch from VC6
to VS 2005?

FWIW, although there were a shed-load of warnings when compiling python
and pythoncore (and a lot more errors when compiling other modules), I
only had to apply one patch to get it working well enough to run
pystone.py.  Without this patch, the VC8 CRT aborts at runtime as soon
as an invalid signal is passed to signal(); which is inevitable given
the current code in the initsignal() method:

for (i = 1; i < NSIG; i++) {
void (*t)(int);
t = PyOS_getsig(i);


Regards,

Trent.

I'll be around for the sprints -- didn't really have a plan as to what I'd like 
to sprint on but if there's some interest in farming Windows developers, I'll 
raise my hand.  Anything in particular you can point myself or others in the 
Windows camp at such that we're a bit better prepared come sprint time (i.e. 
open issues)?

(Also, I'm looking to acquire a new reasonably well-spec'd Windows box for 
work.  If it's available in time for PyCon, I should be able to set up a couple 
of virtual 64-bit Vista/Server 2008 images with VS 2008 dev environments that 
non-Windows developers could use, if that would be desirable.)

Just out of interest, what's the reason for enforcing that the installer must 
be an MSI?  Or, rather, if I were to present an alternative .exe installer that 
ticks all of the above boxes, exceeds the capabilities of the current installer 
and above all is easier to extend and maintain -- would that be a non-starter 
because it's not an MSI?

Yeah, I've dropped Martin a note regarding this.  The community bots refer to 
Windows Server 2003 boxes as just that, so perhaps a rename to 'x86 Windows 
Server 2008' is appropriate.  FWIW as it's a 64-bit box, I'm hoping to get a 
slave set up for 'x64 Windows Server 2008' as well.

(As far as I can see, the x64/x86 nature of the slave is dictated by the 
master, correct?  i.e. I can't tweak/clone this myself?)

Makes sense.  So we're looking at something like:

@rem Sleepycat db
if not exist db-4.4.20 (
svn export http://svn.python.org/projects/external/db-4.4.20
devenv /upgrade db-4.4.20\build_win32\Berkeley_DB.sln
)
if not exist db-4.4.20\build_win32\debug\libdb44sd.lib (
devenv db-4.4.20\build_win32\Berkeley_DB.sln /build Debug
)

I'll test this when I get to work and report back.

[Python-Dev] Windows buildbot test_bsddb3 problems (was RE: Buildbots for trunk are all red)

2008-03-04 Thread Trent Nelson
Spent some time on my buildbot (x86 2k8 trunk) this morning trying to track 
down why test_bsddb3 is failing (trunk with db-4.4.20).  The first test that 
fails is this:

test01_GetsAndPuts (bsddb.test.test_basics.BasicBTreeWithEnvTestCase) ... ERROR

That's slightly misleading though as the test runs fine -- the actual exception 
is being thrown in test_basics.BasicTestCase.tearDown() when os.remove() is 
called against the first db file (i.e. '__db.001'):

WindowsError: [Error 5] Access is denied: 
'c:\users\trent~1.nel\appdata\local\temp\2\db_home2808\__db.001

This isn't surprising, given that the python_d.exe process still seems to have 
__db.001, __db.002 and __db.003 open at the time os.remove() is called.  The 
aforementioned tearDown() method looks like this:

def tearDown(self):
self.d.close()
if self.env is not None:
test_support.rmtree(self.homeDir)
self.env.close()
## Make a new DBEnv to remove the env files from the home dir.
## (It can't be done while the env is open, nor after it has been
## closed, so we make a new one to do it.)
#e = db.DBEnv()
#e.remove(self.homeDir)
#os.remove(os.path.join(self.homeDir, self.filename))
else:
os.remove(self.filename)

If I switch the order of statements such that self.env.close() is called before 
test_suppot.rmtree(self.homeDir), this particular test and a host of others 
that were also failing now pass (a runtime abort is no longer raised by the CRT 
half way into the tests either).  (Note that the order was switched to that 
shown above by Neal in r61052 on Feb 24th, which is when these issues started 
occurring.)

That said, there are still a lot more test failures down the track once this 
change has been made, either via the access denied WindowsError, or a 
DBInvalidArgError, e.g.:

DBInvalidArgError: (22, 'Invalid argument -- configured environment flags 
incompatible with existing environment')

The DBInvalidArgError exception is only raised after a previous WindowsError is 
encountered, so I assume it's a side-effect of the tearDown() method not 
cleaning the environment correctly.

It seems this comment in tearDown() is quite pertinent to our situation:
## Make a new DBEnv to remove the env files from the home dir.
## (It can't be done while the env is open, nor after it has been
## closed, so we make a new one to do it.)
#e = db.DBEnv()
#e.remove(self.homeDir)
#os.remove(os.path.join(self.homeDir, self.filename))

Not sure why this is commented out -- quick search of svn history indicates 
it's been like that for at least the last year and a half.

Will have some more time this evening to spend on this, however, work calls at 
the moment.

Regards,

Trent.

Most of the buildbots are green now!!!

Thank you all! This community is as awesome as Python itself, ;)

Three remains in red, though:

- Alpha Tru64: test_smtplib.py is flaky, and _ssl.c is not compiled
correctly. Neil is hunting this, I think.

- X86 XP-3: seems to crash after test_bsddb3.py.

- X86 XP-4: idem. For this two, how can be tried if the bsddb lib in
those windows is correctly installed?

Thanks again.

[Python-Dev] signal.alarm(3) in trunk test_socketserver.py

2008-03-04 Thread Trent Nelson
r61099 added the following to trunk/Lib/test/test_socketserver.py:

  if __name__ == "__main__":
  test_main()

which breaks platforms that don't have signal.alarm, like, say, !unix ;-)

Actually, signal.alarm() was introduced all over the place in that revision.  I

[Python-Dev] Patch for trunk test_winsound.py (fixes my buildbot)

2008-03-04 Thread Trent Nelson
winsound.Beep fails for me on the 'x86 2k8 trunk' build slave, which is a 
virtual Windows Server 2008 instance running under Hyper-V.  Not surprisingly, 
there's not a single audio-related device on this system.  The attached patch 
to test_winsound.py incorporates the _have_soundcard() checks to the BeepTest 
class, which fixes the problem for me.  (I've also tested the patch on a Vista 
system (that does have a soundcard) and everything works as expected.)

[Python-Dev] Windows buildbots randomly die with twisted ConnectionLost errors?

2008-03-04 Thread Trent Nelson
I've started to see my build slave dying every so often with a twisted error 
half way through tests:
...
test_htmlparser
test_httplib

remoteFailed: [Failure instance: Traceback (failure with no frames): 
twisted.internet.error.ConnectionLost: Connection to the other side was lost in 
a non-clean fashion.
]

Examples:

http://www.python.org/dev/buildbot/all/x86%20W2k8%20trunk/builds/46/step-test/0

http://www.python.org/dev/buildbot/all/x86%20W2k8%20trunk/builds/36/step-test/0

I'm not sure if I should read into the fact that it's occurring after 
networking-oriented tests like test_httplib and test_ftplib.  Running rt.bat on 
the resulting build manually doesn't indicate any errors in these tests.  Have 
other Windows buildbot owners seen this?

I have not observed this behaviour on my buildbots.  Have you looked into

Can someone set me up with a build slave for an x86 FreeBSD box (6.2-STABLE,

[Python-Dev] Windows x64 & bsddb 4.4.20 woes

2008-03-13 Thread Trent Nelson
I've been trying to give the Windows x64 builds a bit of TLC the past few 
evenings.  I managed to get a successful build with all external modules last 
night (Tcl/Tk required about a half a dozen code/configuration changes each in 
order to build in a Windows x64 environment with Visual Studio 9, I'll deal 
with that in a separate thread or roundup issue).

Unfortunately, though, we're back to more bsddb issues.  I got about 15 tests 
in without error before test_whichdb ran, which results in the following being 
called in dbhash.py:

return bsddb.hashopen(file, flag, mode)

I can trace that call to DBEnv_open() in _bsddb.c:

static PyObject*
DBEnv_open(DBEnvObject* self, PyObject* args)
{
int err, flags=0, mode=0660;
char *db_home;

if (!PyArg_ParseTuple(args, "z|ii:open", &db_home, &flags, &mode))
return NULL;

CHECK_ENV_NOT_CLOSED(self);

MYDB_BEGIN_ALLOW_THREADS;
err = self->db_env->open(self->db_env, db_home, flags, mode);
^

Placing a breakpoint at the line above and stepping in results in Visual Studio 
reporting: " A buffer overrun has occurred in python_d.exe which has corrupted 
the program's internal state. Press Break to debug the program or Continue to 
terminate the program.".  FWIW, the exception is being raised as part of the 
/GS buffer overflow checks (implemented in gs_result.c, which is provided in my 
VS9 installation).

This has been annoyingly awkward to debug.  I can't break down that call into 
multiple steps in order to try place breakpoints in the db_static module.  The 
callstack isn't that useful either:

_bsddb_d.pyd!__crt_debugger_hook()
_bsddb_d.pyd!__report_gsfailure(unsigned __int64 StackCookie=2211040)
_bsddb_d.pyd!__GSHandlerCheckCommon(void * EstablisherFrame=0x0021bce0, 
...)
_bsddb_d.pyd!__GSHandlerCheck(_EXCEPTION_RECORD * 
ExceptionRecord=0x0021bbc0, ...)

ntdll.dll!773b59f8()
_bsddb_d.pyd!__os_strdup()  + 0x18 bytes
_bsddb_d.pyd!__os_tmpdir()  + 0x281 bytes

You'd think placing breakpoints in db 4.4.20's __os_strdup and __os_tmpdir 
methods would do something, but alas, the bufferoverflow exception is raised 
before any breakpoints are set.  This makes me suspect there's something funky 
going on with the entire build and linking of db_static (VS should honour those 
breakpoints if the code is being entered, I even added db_static to pcbuild.sln 
and rebuilt but no dice).  I've noticed that they're not using consistent 
compiler flags by default (we use /GS, they use /GS-, we allow function level 
linking, they don't -- note that I did change db_static's options to align with 
_bsddb's but the bufferoverflow exception is still being thrown).

Greg, Jesús, I'm CC'ing you guys as stfw'ing seems to bring back you two the 
most when it comes to bsddb issues.  I've still got a list of things to try 
with regarding to debugging this x64 issue, but I wanted to reach out now to 
see if anyone else had encountered it before.  Has bsddb ever been built 
successfully on Win64 and passed all tests or am I venturing into new ground?

Martin, you've changed externals/bsddb-4.4.20 with regards to x64 builds 
recently -- have you been able to get things working in your x64 environments?

Trent.

Hey Greg,

I'm at PyCon indeed, staying through the sprints 'til next Thursday.  I'll drop 
you a note offline re catching up.

The other query I had was whether or not I should try a later version of 
BerkeleyDB -- are we committed to 4.4.20 (or 4.4.x?) for 2.6/3.0 or is it worth 
investigating newer versions?  Martin/Jesus, any thoughts on this?

Regarding the db_static build and conflicting compile/link options -- I'm going 
to bring the db_static source directly into the _bsddb project (for now) which 
should make this a lot easier to debug.

I haven't built the bsddb stuff on windows myself in a few years and have never 
had access to a windows x64 system so I'm no silver bullet.  Making the 
BerkeleyDB compile and link options match with those of python is the first 
place I'd start.  Also you should be able to make a debug build of BerkeleyDB 
(though it sounds like you may have tried that already?).  Next off in the 
debugging i'd take a look at the assembly to see what exactly it was failing to 
do.

If you're at PyCon right now we should meet up and try to figure it out (I just 
arrived).

Re: [Python-Dev] Windows x64 & bsddb 4.4.20 woes

2008-03-13 Thread Trent Nelson

Ah, and to think I just fixed 4.4.20 ;-)

Removing the dependency on db_static.vcproj and merging the relevant source 
code files into _bsddb.vcproj did the trick -- all x64 bsddb-related tests now 
pass.  The only issue with this approach is that it locks _bsddb.vcproj into 
4.4.20.  However, considering that this approach (i.e. bringing their source 
files into our build instead of linking against a static lib compiled with 
wildly incompatible flags) only took me about two minutes to implement and 
immediately fixed every bsddb problem I was encoutering, I'm convinced it's the 
right way to go.  (I can separate the dependencies easily enough.)

Woeful PyCon/hotel connectivity is preventing me from getting to 
bugs.python.org at the moment; I'll raise a ticket later to capture this stuff 
and we can move the discussion there once I've attached some patches.

Trent.

Python 2.6/3.0 should be built on Windows using BerkeleyDB 4.5.x for now.  
4.6.x is out but has some bugs on some platforms so i don't recommend shipping 
our release using it; 4.7.x is in beta and some bugs are being worked on; if 
its out and shows no signs of obvious issues before the 2.6/3.0 beta period is 
over I recommend we build our binary releases using it.  Otherwise 4.5 it will 
be.  There is no reason to use 4.4.x.



Regarding the db_static build and conflicting compile/link options -- I'm going 
to bring the db_static source directly into the _bsddb project (for now) which 
should make this a lot easier to debug.

Trent.

I haven't built the bsddb stuff on windows myself in a few years and have never 
had access to a windows x64 system so I'm no silver bullet.  Making the 
BerkeleyDB compile and link options match with those of python is the first 
place I'd start.  Also you should be able to make a debug build of BerkeleyDB 
(though it sounds like you may have tried that already?).  Next off in the 
debugging i'd take a look at the assembly to see what exactly it was failing to 
do.

If you're at PyCon right now we should meet up and try to figure it out (I just 
arrived).

I've been trying to give the Windows x64 builds a bit of TLC the past few

order to build in a Windows x64 environment with Visual Studio 9, I'll deal 
with that in a separate thread or roundup issue).

Unfortunately, though, we're back to more bsddb issues.  I got about 15 tests 
in without error before test_whichdb ran, which results in the following being 
called in dbhash.py:

return bsddb.hashopen(file, flag, mode)

I can trace that call to DBEnv_open() in _bsddb.c:

static PyObject*
DBEnv_open(DBEnvObject* self, PyObject* args)
{
int err, flags=0, mode=0660;
char *db_home;

if (!PyArg_ParseTuple(args, "z|ii:open", &db_home, &flags, &mode))
return NULL;

CHECK_ENV_NOT_CLOSED(self);

MYDB_BEGIN_ALLOW_THREADS;
err = self->db_env->open(self->db_env, db_home, flags, mode);
^

Placing a breakpoint at the line above and stepping in results in Visual Studio 
reporting: " A buffer overrun has occurred in python_d.exe which has corrupted 
the program's internal state. Press Break to debug the program or Continue to 
terminate the program.".  FWIW, the exception is being raised as part of the 
/GS buffer overflow checks (implemented in gs_result.c, which is provided in my 
VS9 installation).

This has been annoyingly awkward to debug.  I can't break down that call into 
multiple steps in order to try place breakpoints in the db_static module.  The 
callstack isn't that useful either:

_bsddb_d.pyd!__crt_debugger_hook()
_bsddb_d.pyd!__report_gsfailure(unsigned __int64 StackCookie=2211040)
_bsddb_d.pyd!__GSHandlerCheckCommon(void * EstablisherFrame=0x0021bce0,

I reviewed all the compiler options used by db_static.vcproj -- the only thing 
I needed to bring over was -DDIAGNOSTIC for debug builds.  Everything else 
either had no impact and could be safely dropped, or conflicted with compiler 
options used by the rest of the python build (function level linking, buffer 
overflow checks, etc).

Regarding support for users who want to build with different versions of bsddb; 
if they want a functional build that passes tests they're going to have to do 
something similar to the work I've done anyway.  As it stands now, the .lib 
generated by db_static.vcproj for x64 builds just straight out does not work.  
That can be fixed in two ways: coerce db_static.vcproj into matching our build, 
or mimicking db_static in a new .vcproj that's contained with our build, 
inheriting our property sheets.  I chose the latter.

What are we referring to here?  Calling the W versions explicitly and using 
wchar_t for everything, or using the TCHAR/TEXT() approach and keeping the API 
calls the same, letting the #define UNICODE do the work behind the scenes?

Sounds like a challenge if ever I've heard one -- care to wager a beer on it?  
(Only applies to buildbots that are connected/online.)

(FWIW, I've got the x64 Windows build green on my dev server, tcl/tk and bsddb 
required patching, so did some tests, and so did some C code -- I'm in the 
process of filtering the efforts back into the tracker.)

Yeah test_tokenize is weird, I've been looking into it as well.  Here's a

The following is at the end of the doctests in test_tokenize:

On that first line, 'f' is lib/test/tokenize_tests.txt, so basically, it's 
grabbing ten random test*.py files in lib/test and running 
untokenize(generate_tokens(f.readline)) on each one.  In order to figure out 
which file it's dying on, I added the following to test_tokenize.py:

def test_tokenize_all():
import glob
import os
tempdir = os.path.dirname(__file__) or os.curdir
testfiles = glob.glob(os.path.join(tempdir, "test*.py"))
for file in testfiles:
print("processing file: " + file)
print("roundtrip(open(file)): " + roundtrip(open(file)))

2008-03-16 Thread Trent Nelson
As it turns out, it's not memory related, but has to do with tokenize not 
supporting coding cookies in files.  Mark picked up on this and linked it to an 
issue already in roundup that was raised way back in 2003: 
http://bugs.python.org/issue71988.

I've just finished patching test_tokenizer.py to better represent this test 
case -- the current implementation doesn't lend itself very well to being 
debugged when things go wrong (I think Mark and I both felt like we were on a 
bit of a wild goose chase).  I've fixed that and have a bunch of text files 
with various utf-8/bom sig permutations that are now used to test tokenizer's 
compliance with PEP 0263.  I'll upload that now then move on to actually 
patching tokenizer.py.

Re: [Python-Dev] how to build extensions for Windows?

2008-03-19 Thread Trent Nelson
Having recently sunk a lot of time into the Windows build process, I'd 
recommend going with Visual C++ Express 2008 rather than MinGW, as this is the 
official compiler for 2.6/3.0.  (You can download a free copy.)

FWIW, I've probably been working on the Windows build side of things on and off 
for the past month or so, and we've only just reached a point where 32bit and 
64bit Windows builds are compiling with all extension modules (bsddb, tcl/tk, 
ssl etc) and passing all tests (most work has gone into the x64 builds though, 
the 32-bit ones were already green on XP and below for 32bit).  Using MinGW/gcc 
on Windows hasn't seen anywhere near so much attention, so, YMWV.

In terms of my Windows-oriented priorities, they are as follows:
 - Get 3.0 32/64 Windows builds actually compiling successfully and then 
passing all tests (given that all build slaves for 3.0 are red that's not 
exactly a quick action).
 - Move on to the MSI installer improvements for 2.6/3.0, specifically with 
regards to the VCRT9 runtime and signing of the installer/binaries.
 - Maybe putting some cycles into Python builds on MinGW.  To be honest though, 
the main motivation for doing that will be to demonstrate that a Python 
executable compiled with Visual Studio 2008 Professional with Profile Guided

Subject: [Python-Dev] how to build extensions for Windows?

I've set up a Parallels virtual machine on my Mac, and have succeeded
in getting Windows XP running in it!  And I've installed MinGW, as
well.  Now I'd like to learn how to build the SSL module from source
on Windows for Python 2.5.2.  Is there any documentation on the
process of building an extension from scratch that's appropriate for
someone who doesn't know much about Windows?  I'm looking for
step-by-step.

What about this?  http://www.mingw.org/MinGWiki/index.php/Python%20extensions

[Python-Dev] trunk buildbot status

2008-03-19 Thread Trent Nelson
Quick update on the status of the trunk buildbots:

Failing:
[x86 gentoo trunk (Neal Norwitz)]
This has been failing at the same point for the past couple of days now:
test_sqlite
command timed out: 1800 seconds without output, killing pid 15168
process killed by signal 9
program finished with exit code -1

None of the other buildbots seem to be encountering the same problem.  Neal, 
got any idea what's going on with this one?

[alpha True64 5.1 trunk (Neal Norwitz)]
test_tarfile started failing recently (within the past few days) with CRC 
checks.  See 
http://www.python.org/dev/buildbot/trunk/alpha%20Tru64%205.1%20trunk/builds/2712/step-test/0.
  Greg updated the test such that it prints out some more detail about the 
failure so we're waiting on that at the moment.

[hppa Ubuntu trunk (Matthias Klose)]
This has been consistently failing in test_socketserver for as long as I can 
remember:
test_socketserver
make: *** [buildbottest] Alarm clock
program finished with exit code 2

I just updated that test such that it waits 20 seconds instead of 3 seconds at 
the end of the test if the server hasn't shutdown -- waiting for the test 
results of this still.

[x86 XP trunk (Joseph Armbruster)]
This box didn't survive the recent build changes, but I can't figure out why, 
none of the other Windows boxes encounter this error:
The following error has occurred during XML parsing:
File: C:\python\buildarea\trunk.armbruster-windows\build\PCbuild\_bsddb.vcproj
Line: 179
Column: 1
Error Message:
Illegal qualified name character.
The file 
'C:\python\buildarea\trunk.armbruster-windows\build\PCbuild\_bsddb.vcproj' has 
failed to load.

Can someone check a clean trunk build on a Windows system that *only* has 
Visual C++ Express 2008?  The latest build system updates don't rely on any 
features of Visual Studio Professional, but the tools use a lot of common 
files, and perhaps a Service Pack needs to be applied or something.

[amd64 XP trunk (Thomas Heller)]
Builds fine, all tests pass except for test_largefile, which is failing as 
there's no more space left on the drive ;-)

[x86 XP-4 trunk (David Bolen)]
This is currently flagged as having failed test, but I don't think it's 
finished building since the finalised build updates, so hopefully the BSDDB 
errors in the last run will be resolved when it finished the latest build.

[x86 FreeBSD 2 trunk (Jeroen Ruigrok van der Werven)]
This is a FreeBSD 6.3-STABLE box (which switched to curses 5.6 from 5.2) -- 
there's been an ongoing thread with regards to why curses has started failing, 
Jeroen can probably provide more info on that.  Either way I don't anticipate a 
quick fix for this particular slave, unfortuantely.

Neal/Martin, I'd like to promote the following slaves to the stable list:
[g4 osx.4]
[x86 W2k8]
[AMD64 W2k8]
[ppc Debian unstable]
[sparc Ubuntu]
[sparc Debian]
[PPC64 Debian]
[S-390 Debian]
[x86 XP-3]
[amd64 XP]
[x86 FreeBSD]
[x86 FreeBSD 3]

The trunk builds of these slaves have been the most reliable since I've been 
tracking.

   Trent.

I'd recommend cd'ing to your trunk root directory and running 
Tool\buildbot\build.bat from there -- it'll automatically check out all the 
dependencies and build via command line with vcbuild (building via Visual 
Studio usually always Does The Right Thing, command line builds often take a 
bit more coercing).

I just built the trunk on a Windows XP x86 box that only has Visual C++
Express 2008 installed.  I got a bunch of errors with sqlite, tcl,
db-4.4.20, and ssl, but the interpreter built and appears to run ok.

But since I don't have bsddb installed, I don't think I'm executing the
portion of the build process that you find failing.

I don't have time to install bsddb tonight, but I can do that in about
24 hours if you still need me to.

Okay, that's extremely helpful.  With that (and installing nasmw.exe), a
trunk checkout builds correctly and passes all tests (although skipping
test_tcl) on my box.  As I said, it's XP x86 with 2008 Express Edition only.

Let me know if I can provide any other information.  Unfortunately I
don't have access to this box during the work day (EDT), and I'm leaving
for vacation tomorrow (Friday).  But I'll help as best I can.

I haven't looked into all the various places the tests write temp files to, but 
if we could localise everything to a common root directory, i.e. 
%TEMP%\python-regrtest, we could then attempt to blow this away at the start of 
regrtest.py before any tests run, and refuse to run if this fails.  This would 
be in combination with the unlinking/renaming approach discussed.  This 
approach seems like it would cover all bases a bit more effectively.

Is this *really* the case still?  Who are these rogue committers? ;-)

I think holding a developer accountable for merging or blocking to py3k when 
they commit to trunk is a great idea.  Who better to pass judgement on such an 
activity than the person closest to it?

I'm with Martin on this one as well I think.  If I understand correctly, you're 
proposing:

PCbuild - may have contents of x86 or x64 depending
  on the build machine's architecture
PCbuild/amd64   - always x64
PCbuild/x86 - always x86

And what we've currently got is:

PCbuild/- always x86
PCbuild/amd64   - always x64

I think this is fine; we don't really have a notion of compiling for a native 
platform, nor is the build machine's architecture factored into the equation.  
I believe this is a Good Thing.  If you want a 32-bit build, use the 'Win32' 
target platform in VS; if you want a 64-bit build, use 'x64'.

I feel for the poor NOC engineers at my colo that freak out when some random 
server in a farm of thousands starts making bizarre sounds.

I detest test_winsound.  There are so many corner cases you need to account for 
that makes the test pointless as you end up wrapping everything in except: pass 
blocks.  Does the system have a legacy beep driver?  Is it enabled?  Is it 
disabled?  Is there a sound card?  Is it enabled or disabled?  Pah!

+1 to removing audio out of -uall, if only for the sake of cats, erroneously 
red buildbots, and poor ServerCentral NOC engineers.

Ah, right, I wasn't thinking about the implication of code affecting the C base 
for some reason, but that's entirely reasonable.  Perhaps each developer should 
be accountable for either:

a) blocking
b) merging, if they're able to do so
c) if they're unable to merge, replying to the relevant python-checkins@ e-mail 
indicating that they're unable to handle trunk -> py3k for whatever reason 
(e.g. not familiar with py3k code base)

Other developers could then pitch in and help merge if someone requests it via 
e-mail.  I'd think that would make The Merger's life easier.

[Python-Dev] Tools\buildbot\kill_python.c can't be helping our cause

2008-04-02 Thread Trent Nelson
Looking into some of the recent Windows buildbot failures, I see things like 
this:

sqlite3 : error PRJ0008 : Could not delete file 
'c:\buildbot\trunk.heller-windows-amd64\build\PCbuild\amd64\sqlite3_d.dll'.

build-amd64.bat doesn't go through the kill_python.c hoopla, so I figure the 
above error is being caused by the fact that an erroneous/stalled python_d.exe 
from a previous run is still open.  I was looking at modifying kill_python.c to 
accept an 'x64' argument if we want to kill amd64\python_d.exe instead of the 
usual 32-bit exe, however, this caught my attention:

if ((strstr(path, "pcbuild\\python_d.exe") != NULL) ||
(strstr(path, "\\build\\python.exe") != NULL)) {
printf("Terminating %s (pid %d)\n", path, pids[i]);
if (!TerminateProcess(hProcess, 1)) {
printf("Termination failed: %d\n", GetLastError());
return 1;
}
return 0;

That'll kill the first python_d.exe instance it finds matching the given path; 
given that our buildbots run trunk/release25-maint/py3k in parallel, it seems 
as though it wouldn't be hard for us to get into a situation where 
kill_python.exe ends up killing the wrong python_d.exe (i.e. trunk checkin, 
trunk builds, starts testing, py3k checkin, calls kill_python.exe, kills 
trunk's python_d.exe that was in the middle of testing).

That can't be helping our cause, unless I'm missing something...  Unless anyone 
advises otherwise, I'll start on a patch.

Spent a bit of time on it this evening; as it happens, in order to enumerate 
64-bit processes, you need to be a 64-bit process yourself.  As it's much 
easier managing 32-bit vs. x64 binaries when they're a .vcproj part of 
pcbuild.sln, I'm looking into adding kill_python as a .vcproj and configure the 
solution such that it builds and runs this before any other project.  That'll 
automatically take care of choosing the right version to run depending on 
whether 'Win32' or 'x64' is selected as the platform.  It'll also simplify the 
verification logic that checks if it's the right python_d.exe -- the path of 
the .exe needs to match the path of the running kill_python.exe.

Re: [Python-Dev] fixing tests on windows

2008-04-03 Thread Trent Nelson
[Disclaimer: thought dump e-mail, signal to noise ratio may be subpar.]

Sounds like you're at least making steps forward in the right direction, 
despite the activity probably being quite disheartening.  Based on what you've 
said below and the rest of the conversation, here are my thoughts for an 
approach:

1.  For a given python[_d].exe, always use the same test directory, but hash it 
against the entire python process path such that it's unique only for a given 
python instance.
2.  Make sure every time a test wants a temp file, it gets a unique one in this 
directory.  Sounds like your TESTFN modification would take care of this for 
those tests using TESTFN; if TESTFN is the preferred approach then any other 
tests using tempfile or hardcoding file names would then be changed to use this 
instead.
3.  In order to address tests that either call the test_support methods for 
removing files/directories, or those that call os.(unlink|remove), do what ever 
needs to be done to make these no-ops on Windows if an error occurs.
4.  At the end of the regrtest.py run, create a suspended arbitrary process 
(i.e. explorer.exe), hijack the main thread context of the process and inject a 
routine (i.e. overwrite the thread context's instruction pointers) that takes 
care of removing the temporary directory that was used for testing -- patiently 
re-trying if any failures occur until all rogue processes also accessing the 
file(s) stop doing so.  Resume the thread before exiting python.

Heh.  Sounds crazy?  It did to me as well, until I came across 
http://www.catch22.net/tuts/selfdel.asp, which documents the approach.  It's 
not particularly necessary in our case, we could simply spawn another python 
process at the end of regrtest.py that patiently attempts to remove the test 
directory we just used when the python process that was executing regrtest.py 
exits.

We could then modify regrtest.py such that it will use the same approach if the 
hashed test directory already exists at the start of a run and it can't remove 
it via os.unlink.  If we *still* run into issues here on the buildbots, say if 
regrtest.py blocks on our helper process, which for the life of it can't remove 
some/all of the test files -- it'd be interesting to write something that 
grok's all open handles for all processes and attempts to figure out what it is 
that keeps these files open -- i.e. same thing that procexp.exe does when you 
search for a handle.

Or, keeping it simple, rather than a separate process and hashed test directory 
based on python process path, just have a common directory, i.e. 
%TEMP%\python-regrtest, and use an incrementing sequence number for each test 
run's test directory, i.e. if there are directories 001, 002 and 003 in the 
temp dir, when regrtest.py starts, it'll try delete all of these -- if it can't 
(which is what we'd want if another test is already running), it adds 1 to the 
highest numbered directory it couldn't delete.

Guess it all depends on how much effort we want to put into cleaning up our 
test directory really -- just ensuring tests get a clean area and unique file 
names each run is the easy part.

Trent.

[re tests which fail because something's holding a file
open with SHARE_DELETE]

Well I've tried my best, but I can't come up with a solution
which guarantees to overcome this obstacle. I set up a fairly
aggressive directory watcher which, when it sees a test file
being created, takes a SHARE_DELETE handle on it and releases
it immediately. (Guessing that this is what the other apps
are doing).

Running the test suite from HEAD, this generates all manner
of access-denied type errors as per the original output.

I used tempfile to generate a random TESTFN in the current directory
rather than the static @test. And implemented the rename-shim
discussed previously, renaming to a different random name, courtesy
of mktemp. With those in place, most tests run without error. But
I'm still getting errors in the same sort of areas which Steven B
originally reported.

The one error I can't see a way round is the access denied (which
manifests as Permission Error) which is the documented result of
attempting to open a file with a pending delete -- ie the delete
succeeded but hasn't completed yet.

An additional complication is that there are hundreds of
instances throughout the tests where the test simply calls
os.unlink/os.remove to undo the test file. To have some more
robust central deletion I had to go through and update 68 tests.

I'll keep trying, but in the current state I'm not convinced
the situation's improved enough for me to bother uploading
a patch.

[Python-Dev] socket.SOL_REUSEADDR: different semantics between Windows vs Unix (or why test_asynchat is sometimes dying on Windows)

2008-04-03 Thread Trent Nelson
I started looking into this:

http://www.python.org/dev/buildbot/all/x86%20W2k8%20trunk/builds/289/step-test/0

Pertinent part:

test_asyncore

test_asynchat

command timed out: 1200 seconds without output
SIGKILL failed to kill process
using fake rc=-1
program finished with exit code -1
remoteFailed: [Failure instance: Traceback from remote host -- Traceback (most 
recent call last):
Failure: buildbot.slave.commands.TimeoutError: SIGKILL failed to kill process
]

I tried to replicate it on the buildbot in order to debug, which, surprisingly, 
I could do consistently by just running rt.bat -q -d -uall test_asynchat.  As 
the log above indicates, the python process becomes completely and utterly 
wedged, to the point that I can't even attach a remote debugger and step into 
it.

Digging further, I noticed that if I ran the following code in two different 
python consoles, EADDRINUSE was *NOT* being raised by socket.bind():

import socket

Re: [Python-Dev] fixing tests on windows

2008-04-04 Thread Trent Nelson
I agree with Tim, you can jump through as many hoops as you want (setting 
directories private, using %TEMP% exclusively, etc), but I doubt anything is 
going to change the behaviour of things like virus scanners, for example.

Tim, let me know if you need help with anything, perhaps we could set up a 
temporary branch outside of trunk to play around with various approaches to see 
what works best.  This'll ensure we don't adversely affect the main buildbots, 
but also give us the option to get different Windows boxes to build our test 
branch on demand.

The problem is, I think, that it isn't just the Indexing Service
which generates this issue. TortoiseSVN is well known for doing
the same thing, and there could be now and potentially will be
in the future other programs. I don't think that hunting down
and turning off their interference case by case is a viable
solution in the long-term. Although it would obviously be a
way forward in the short term, _faute de mieux_.

I'm inclined to think you're right. And a first pass I had at
producing a solution simply used tempfile to do everything.
Unfortunately that's far more invasive than I was really
comfortable with at the time: at the very least, you have
to patch several tests which fail if there's an (escaped)
backslash in the path.

However, it's clear that my attempt to cause the minimum damage
isn't enough to clear the problem 100%. So I think the next move
is indeed to turn test_support.TESTFN into a function (in some
way) which generates a unique tempfile reference, possibly with
a context manager to clean up. Or something.

The complication is that, while most test simply want a handy
file to exist or be written to, and don't really care what
happens afterwards, some tests are testing the very mechanism
of creating/deleting a file etc. So a wholesale replacement
isn't necessarily straightforward.

On we go.

Hmmm.  When you say rebuild, I assume you mean the change I made to the 
pythoncore project's pre-link step to call kill_python.exe, and not to the 
post-build step of kill_python that runs itself?  Personally, when I'm doing 
development, if I've got the pcbuild\python_d.exe console open, it's usually to 
test one liners, I'm not using it to do anything important.  If I forget to 
close it before I kick off a build, it's annoying running into errors at the 
link stage, I'd certainly prefer the build system to kill off anything that'll 
inhibit a successful link before actually linking.

What do others that do Windows development think?  I don't have a problem 
changing the build behaviour if the approach I've taken is generally disliked.

Digging further, I noticed that if I ran the following code in two different

I think kill_python should only ever be invoked in the build slaves;
it should *not* be part of the regular build. If developers find they
can't build because some files are still open, they should kill
the processes themselves.

Re: [Python-Dev] socket.SOL_REUSEADDR: different semantics between Windows vs Unix (or why test_asynchat is sometimes dying on Windows)

2008-04-04 Thread Trent Nelson
Interesting results!  I committed the patch to test_socket.py in r62152.  I was 
expecting all other platforms except for Windows to behave consistently (i.e. 
pass).  That is, given the following:

import socket
host = '127.0.0.1'
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind((host, 0))
port = sock.getsockname()[1]
sock.close()
del sock

sock1 = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock1.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
sock1.bind((host, port))
sock2 = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock2.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
sock2.bind((host, port))


the second bind should fail with EADDRINUSE, at least according to the 
'SO_REUSEADDR and SO_REUSEPORT Socket Options' section in chapter 7.5 of 
Stevens' UNIX Network Programming Volume 1 (2nd Ed):

"With TCP, we are never able to start multiple servers that bind
 the same IP address and same port: a completely duplicate binding.
 That is, we cannot start one server that binds 198.69.10.2 port 80
 and start another that also binds 198.69.10.2 port 80, even if we
 set the SO_REUSEADDR socket option for the second server."

The results: both Windows *and* Linux fail the patched test; none of the 
buildbots for either platform encountered an EADDRINUSE socket.error after the 
second bind().  FreeBSD, OS X, Solaris and Tru64 pass the test -- EADDRINUSE is 
raised on the second bind.  (Interesting that all the ones that passed have a 
BSD lineage.)

I've just reverted the test in r62156 as planned.  The real issue now is that 
there are tests that are calling test_support.bind_socket() with the assumption 
that the port returned by this method is 'unbound', when in fact, the current 
implementation can't guarantee this:

def bind_port(sock, host='', preferred_port=54321):
for port in [preferred_port, 9907, 10243, 32999, 0]:
try:
sock.bind((host, port))
if port == 0:
port = sock.getsockname()[1]
return port
except socket.error, (err, msg):
if err != errno.EADDRINUSE:
raise
print >>sys.__stderr__, \
'  WARNING: failed to listen on port %d, trying another' % port

This logic is only correct for platforms other than Windows and Linux.  I 
haven't looked into all the networking test cases that rely on bind_port(), but 
I would think an implementation such as this would be much more reliable than 
what we've got for returning an unused port:

def bind_port(sock, host='127.0.0.1', *args):
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((host, 0))
port = s.getsockname()[1]
s.close()
del s

sock.bind((host, port))
return port

Actually, FWIW, I just ran a full regrtest.py against trunk on Win32 with this 
change in place and all the tests still pass.

Thoughts?

Trent.

I agree in principle, Stevens says nothing about what happens if you *do* try 
and bind two sockets on two identical host/port addresses.  Even so, 
test_support.bind_port() makes an assumption that bind() will raise EADDRINUSE 
if the port is not available, which, as has been demonstrated, won't be the

Nod, if SO_EXCLUSIVEADDRUSE is used instead in the code I posted, Windows 
raises EADDRINUSE on the second bind().  I don't have access to any Linux boxes 
at the moment, so I can't test what sort of error is raised with the example I 
posted if listen() and accept() are called on the two sockets bound to 
identical addresses.  Can anyone else shed some light on this?  I'd be 
interested in knowing if the process wedges on Linux as badly as it does on 
Windows (to the point where it's not respecting ctrl-c or sigkill).

Re: [Python-Dev] socket.SOL_REUSEADDR: different semantics between Windows vs Unix (or why test_asynchat is sometimes dying on Windows)

2008-04-06 Thread Trent Nelson
I've attached a patch (http://bugs.python.org/file9966/trunk.2550.patch) to 
issue 2550 that addresses the original problem here: test_support.bind_port() 
potentially returning ports that have already been bound to.  The patch updates 
the tests that relied on this method, such that they call it with the new 
calling convention (test_ftplib, test_httplib, test_socket, test_ssl_socket, 
test_asynchat, test_telnetlib).

Any objections to the patch?  Would like to commit it sooner rather than later, 
as it'll fix my buildbots from wedging on test_asynchat at the very least.

[Python-Dev] Changing all network-oriented tests to facilitate (virtually unlimited) parallel test execution [Issue#: 2550]

2008-04-08 Thread Trent Nelson

I've forwarding my most recent update to issue 2550 here such that the proposed 
patch (and in general, the approach to network-oriented test cases) can be 
vetted by a wider audience:

http://bugs.python.org/file9980/trunk.2550-2.patch

This patch works towards fixing a large proportion of the tests that were 
written in such a way that often leads to buildbot errors when port conflicts 
arise.  With this patch applied, I can run many instances of the test suite in 
parallel and none of the network-oriented tests fail (which they do currently 
if you try and do this).

Plenty of discussion (mostly me replying to my own comments) on the subject at: 
http://bugs.python.org/issue2550.

Anyone have any issues with this new approach?  I'm particularily interested in 
whether or not people disagree with the assumption I've drawn regarding never 
using SO_REUSEADDR in tests for TCP/IP sockets (see below).

Trent.

Subject: [issue2550] SO_REUSEADDR doesn't have the same semantics on Windows    
as on Unix

Trent Nelson <[EMAIL PROTECTED]> added the comment:

Invested quite a few cycles on this issue last night.  The more time I
spent on it, the more I became convinced that every single test working
with sockets should be changed in one fell swoop in order to facilitate
(virtually unlimited) parallel test execution without fear of port
conflicts.

I've attached a second patch, trunk.2550-2.patch, which is my progress
so far on doing just this.  The main changes can be expressed by the
following two points:

a) do whatever it takes in network-oriented tests to ensure
   unique ports are obtained (relying on the bind_port() and
   find_unused_port() methods exposed by test_support)

b) never, ever, ever call SO_REUSEADDR on a socket from a test;
   because we're putting so much effort into obtaining a unique
   port, this should never be necessary -- in the rare cases that
   our attempts to obtain a unique port fail, then we absolutely
   should fail with EADDRINUSE, as the ability to obtain a unique
   port for the duration of a client/server test is an invariant
   that we *must* be able to depend upon.  If the invariant is
   broken, fail immediately (don't mask the problem with
   SO_REUSEADDR).

With this patch applied, I can spawn a handful of Python processes and
run the entire test suite (without -r, ensuring all tests are run in
the same order, which should encourage port conflicts (if there were
any)) without any errors*.  Doing that now is completely and utterly
impossible.

[*] Well, almost without error.  All the I/O related tests that try and
open @test fail.

I believe there's still outstanding work to do with this patch with
regards to how the intracacies of SO_REUSEADDR and SO_EXCLUSIVEADDRUSE
should be handled in the rest of the stdlib.  I'm still thinking about
the best approach for this.  However, the patch as it currently stands
is still quite substantial so I wanted to get it out sooner rather than
later for review.

(I'll forward this to python-dev@ to try and encourage more eyes from
people with far more network-fu than I.)

This patch works towards fixing a large proportion of the tests that were

parallel and none of the network-oriented tests fail (which they do currently

Plenty of discussion (mostly me replying to my own comments) on the subject at:

Anyone have any issues with this new approach?  I'm particularily interested in 
whether or not people disagree with the assumption I've drawn regarding never 
using SO_REUSEADDR in tests for TCP/IP sockets (see below).

   Trent.

I think your assumptions are fair.

Note that not using SO_REUSEADDR can reserve the port for a few minutes beyond 
the actual unbinding destruction of the server socket on some OSes but with 
tens of thousands of ports available and likely not more than 1-200 being 
needed by a full test suite run and how long the test suite takes to run I 
think that is acceptable and is not a problem we're likely to ever run into 
(fix it only iffwe ever do).

I don't hold any weight to rumblings regarding "not changing the tests if 
possible".  The tests need to change.  They were never written with the intent 
to run in parallel without any resource contention.  That's an important goal, 
now.  Please send over any patches you've got, everything will be useful!  Now 
that the dust has (sort of) settled on the network-oriented tests, I'm ready to 
start attacking the I/O ones.

We're in the process of decommissioning the box the 'x86 FreeBSD 3' build slave

[Python-Dev] Global Python Sprint Weekends: May 10th-11th and June 21st-22nd.

2008-04-16 Thread Trent Nelson

Following on from the success of previous sprint/bugfix weekends and
sprinting efforts at PyCon 2008, I'd like to propose the next two
Global Python Sprint Weekends take place on the following dates:

* May 10th-11th (four days after 2.6a3 and 3.0a5 are released)
* June 21st-22nd (~week before 2.6b2 and 3.0b2 are released)

It seems there are a few of the Python User Groups keen on meeting
up in person and sprinting collaboratively, akin to PyCon, which I
highly recommend.  I'd like to nominate Saturday across the board
as the day for PUGs to meet up in person, with Sunday geared more
towards an online collaboration day via IRC, where we can take care
of all the little things that got in our way of coding on Saturday
(like finalising/preparing/reviewing patches, updating tracker and
documentation, writing tests ;-).

For User Groups that are planning on meeting up to collaborate,
please reply to this thread on python-dev@python.org and let every-
one know your intentions!

As is commonly the case, #python-dev on irc.freenode.net will be
the place to be over the course of each sprint weekend; a large
proportion of Python developers with commit access will be present,
increasing the amount of eyes available to review and apply patches.

For those that have an idea on areas they'd like to sprint on and
want to look for other developers to rope in (or just to communicate
plans in advance), please also feel free to jump on this thread via
python-dev@ and indicate your intentions.

For those that haven't the foggiest on what to work on, but would
like to contribute, the bugs tracker at http://bugs.python.org is
the best place to start.  Register an account and start searching
for issues that you'd be able to lend a hand with.

All contributors that submit code patches or documentation updates
will typically get listed in Misc/ACKS.txt; come September when the
final release of 2.6 and 3.0 come about, you'll be able to point at
the tarball or .msi and exclaim loudly ``I helped build that!'',
and actually back it up with hard evidence ;-)

Bring on the pizza and Red Bull!

Trent.

[Python-Dev] Code signing of Windows .msi/.dll/.exe's for 2.6/3.0

2008-04-17 Thread Trent Nelson

Friendly poke to see if there's been any progress on acquiring the relevant

Re: [Python-Dev] Code signing of Windows .msi/.dll/.exe's for 2.6/3.0

2008-04-17 Thread Trent Nelson

>  * Why the binaries should be signed?

Makes the installation process on Windows Vista and Server 2008
a little nicer; instead of getting an "unknown-executable-could-
be-a-virus-aa-watchout"-type dialog with a big red flag,
you get a less threatening message saying that you're about to
run something that's been digitally signed by the Python Software
Foundation.  (I've come across a few entities (NSA, government
bodies, etc), who mandate that all installers/binaries they get
must be digitally signed.)

>  * What is required to sign the binaries?

 1. Obtain a code signing certificate from someone.  I used VeriSign.
You end up with an .spc and a .pvk file.  You need to combine them
into a single .pfx file via a tool called pvk2pfx.exe:

Usage:
pvk2pfx -pvk  [-pi ] -spc 
   [-pfx  [-po ] [-f]]

-pvk   - input PVK file name.
-spc   - input SPC file name.
-pfx   - output PFX file name.
-pi- PVK password.
-po- PFX password; same as -pi if not given.
-f   - force overwrite existing PFX file.

if -pfx option is not given, an export wizard will pop up. in
this case, options -po and -f are ignored.

C:\..> pvk2pfx.exe -pvk verisign-privatekey.pvk -pi ** -spc 
onresolve-verisign.spc -po ** -pfx onresolve-verisign.pfx

  3. The resulting .pfx file, onresolve-verisign.pfx in this case, can
 then be installed as a 'Personal' certificate in Windows, using the
 Certificate Management facility (CertMgr.exe).  When you install it,
 you provide a name that the certificate can be referred to by apps;
 in my case I just used 'VeriSign'.  This name is used below by the
 signtool.exe app.

  4. Sign the executable, MSI or DLL as follows:

C:\..> signtool.exe sign /i "VeriSign" /d "Python 2.6.0" /du 
http://www.python.org /t http://timestamp.verisign.com/scripts/timstamp.dll 
Python-2.6.msi
Successfully signed and timestamped: Python-2.6.msi

>  * Which binaries should be signed?

Personally, once I figured out the steps above, I hooked the signing
process into all my Visual Studio projects as a post-build step, such
that I sign all .exe and .dll files.  Not really necessary, but eh,
it does have the advantage of looking more professional (users can
view properties on the .dll, for example, and see that it's been
digitally signed by the PSF).  Additionally, it prevents any tampering;
Windows can detect if it's been altered in any way since it's been
signed, and will flat out prevent it from being loaded/run if that's
the case.

I remember those rampant BSDDB crashes on Windows well.  I brought this up with 
Martin at PyCon; I really don't think we can fault BSDDB here -- basically, the 
tests weren't cleaning up their environment in the right order, so BSDDB was 
getting passed completely and utterly bogus values.  I *think* I managed to 
persuade Martin that this was indeed our fault, and we can't really hold BSDDB 
accountable.  (My argument being that if a 3rd party app says the behaviour of 
a method is undefined if you pass it a null pointer, and you pass it a null 
pointer, and it crashes your program, it's your fault, not theirs.)

Once this was addressed, the BSDDB tests ran more or less on Windows 32-bit 
without error.  Windows x64 was another matter though -- I traced the problem 
down to wildly conflicting compiler and linker flags between our Python build 
and how we were building BSDDB (or rather how BSDDB builds out of the box on 
Windows).

My solution was to drop our reliance on the Berkeley_DB.sln/db_static.vcproj 
files completely, and mimic a bsddb44 vcproj in our own pcbuild.sln, which 
basically meant all the BSDDB source code got built in the exact same fashion 
as the rest of Python.  I also took this approach with sqlite3 and it's worked 
really well -- there have been no issues with either module since this change.

I've also got bsddb45.vcproj and bsddb46.vcproj projects floating around in one 
of my local branches somewhere.  These mimic the corresponding BSDDB projects, 
with the intent being that when it comes to release time for 2.6 and 3.0, we'd 
make a decision about which one to ship with, and then set the Python _bsddb 
module to use that.  I should probably pick that up again...

Hope this clarifies things...

Trent.

Great!  Once you've settled in with your changes let me know and I'll help with

[Python-Dev] Do we still need BaseAddress in .vcproj files?

2008-04-25 Thread Trent Nelson

I just did this locally to all my .vcproj files for .pyds:

-  BaseAddress="0x1e00"
+  RandomizedBaseAddress="2"

This was partly out of curiosity, and partly because it was quicker doing that 
than finding a new unique base address to use for a new module I added to my 
local tree.  Rebuilt everything and ran a full regression test, and everything 
passed.  What am I missing?  Do we have parts of Python that rely on finding 
modules at explicit base addresses?  Is BaseAddress a relic from the past?  
Christian or Martin?

[Python-Dev] socket.try_reuse_address()

2008-04-29 Thread Trent Nelson

Since the recent changes to networking-oriented tests (issue 2550, r62234 and 
r62237), I think it's safe to say stability of the test suite on all the 
non-Windows platforms has improved significantly in this area (I don't recall 
seeing any socket errors in *nix buildbot logs since those commits).

However, Windows buildbots are still periodically failing.  More specifically, 
my Windows buildbots are still failing.  One thing that's different about my 
buildbots is that two are being run at the same time for both trunk and py3k -- 
one doing an x86 build, the other doing x64 build.

Since the changes in the aforementioned revisions, the behaviour of my 
buildbots has definitely improved -- they no longer completely wedge on 
test_async(chat|core), mainly due to abolishing all use of SO_REUSEADDR as a 
socket option in any network-oriented tests.

However, periodically, they're still dying/failing in a variety of ways -- see 
relevant log snippets at the end of this e-mail for examples.  I attribute this 
to the fact that SO_REUSEADDR is still set as a socket option in asyncore.py 
and SocketServer.py.  Basically, SO_REUSEADDR should *never* be set on Windows 
for TCP/IP sockets.  Using asyncore.py as an example, here are two ways we 
could handle this:

Yeah, that's a fair point, it's the behaviour of the underlying Winsock API 
we're targeting, so it would apply to Cygwin as well.  (And CE and anything

including Jython and IronPython -- which all exhibit the same undesirable

Oops, that last line should have been:

Interesting, which version of Jython were you using?

That didn't work for me.  I assume the following works for you:

System.getProperty('os.name').lower().startswith('windows')

I... I think I might have already done this, inadvertently.  I
needed an x64 VS2010 debug build of Subversion/APR*/Python a few
weeks ago -- forgetting the fact that we're still on VS2008.

By the time I got to building Python, I'd already coerced everything
else to use VS2010, so I just bit the bullet and coerced Python to
use it too, including updating all the buildbot scripts and relevant
externals to use VS2010, too.

Things that immediately come to mind as potentially being useful:

  * Three new buildbot scripts:
- build-amd64-vs10.bat
- clean-amd64-vs10.bat
- external-amd64-vs10.bat

  * Updates to externals/(tcl|tk)-8.5.9.x so that they both build with
VS2010.  This was a tad fiddly.  I ended up creating makefile.vs10
from win/makefile.vc and encapsulating the changes there, then
calling that from the buildbot *-vs10.bat scripts.  I had to change
win/rules.vc, too.

  * A few other things I can't remember off the top of my head.

So, I guess my question is, is that work useful?  Based on Martin's
original list, it seems to check a few boxes.

Brian, what are your plans?  Are you going to continue working in
hg.python.org/sandbox/vs2010port then merge everything over when
ready?  I have some time available to work on this for the next
three weeks or so and would like to help out.

Regards,

Trent.

Before I go updating tcl/tk, any thoughts on bumping our support to
the latest revision, 8.5.11?

I guess the same question applies to all the externals, actually
(zlib, openssl, sqlite, bsddb, etc).  In the past we've typically
bumped up our support to the latest version prior to beta, then
stuck with that for the release's life, right?

Semi-related note: is svn.python.org/externals still the primary
repo for externals?  (I can't see a similarly named hg repo.)

Greetings,

The company I work for has an IBM P-690 server that is in the process of

little to no resale value, and will probably be junked. I'd rather it go
to a good home, and having taken advantage of the work of the python
development community for a number of years (we use python extensively
in system admin and database work), I saw this as an opportunity to give
back a little.

So, If anyone is interested in this machine, please let me know. We are
looking at perhaps a November time frame for when it will be removed
from our remote site. The P690 is no small machine, it is the size of a
full rack and has 32 Power4 processors in it and takes (I believe) 2 or
3 phase 220 Volt power. It weighs nearly a ton. We are running AIX5.3 on
it, but I believe that the machine is capable of running a PowerPC
flavor of Linux as well. This would make a great test machine for python
HPC modules or as a community box where developers could test their code
against a PowerPC architecture. It has lots of life left and I'd rather
see it put to use then thrown away.

[Python-Dev] Snakebite, buildbot and low hanging fruit -- feedback wanted! (Was Re: SSH access against buildbot boxes)

On the other side I perfectly understand how opening up blanket ssh
access is not something everyone is comfortable with doing.
AFAICR there was someone who was setting up an evironment to solve
exactly this problem but I'm not sure whether this is already usable.


Dealing with exactly this problem is one of the goals of the Snakebite project.

As far as I know, the folks behind that project are still working on
it - I've cc'ed Trent Nelson to see if he can provide any additional
info on the topic.


Thanks for the ping Nick, I might have missed this otherwise.  Good 
timing, too, as Titus and I were just discussing which low hanging 
fruit/pain points Snakebite should tackle first (now that all the server 
room stuff has finally been taken care of).


Luckily, the problems that we faced 2.5 years ago when I came up with 
the idea of Snakebite are still just as ever present today ;-)


1.  Not having access to buildbots is a pain when something doesn't work 
right.  Doing dummy debug commits against trunk to try and coerce some 
more information out of a failing platform is painful.  Losing a build 
slave entirely due to a particularly hard crash and requiring the 
assistance of the owner is also super frustrating.


2.  The buildbot web interface for building non-(trunk|2.x|py3k) 
branches is also crazy unfriendly.  Per-activity branches are a great 
way to isolate development, even with Subversion, but it kinda' blows 
that you don't *really* get any feedback about how your code behaves on 
other platforms until you re-integrate your changes back into a mainline 
branch.  (I'm sure none of us have been masochistic enough to manually 
kick off individual builds for every platform via the buildbot web page 
after every commit to a non-standard branch.)


So, enter Snakebite.  We've got three racks filled with way more 
hardware than I should have ever purchased.  Ignoring the overhead of 
having to set machines up and whatnot, let's just assume that over the 
next couple of months, if there's a platform we need a stable buildbot 
for, Snakebite can provide it.  (And if we feel like bringing IRIX/MIPS 
and Tru64/Alphas back as primary platforms, we've got the hardware to do 
that, too ;-).)


Now, the fact that they're all in the one place and under my complete 
control is a big advantage, as I can start addressing some of the pain 
points that lead me down this twisted path 2.5 years ago.


I'd like to get some feedback from the development community on what 
they'd prefer.  In my mind, I could take one of the following two steps:


1.  Set up standard build slaves on all the platforms, but put something 
in place that allowed committers to ssh/mstsc in to said slaves when 
things go wrong in order to aid with debugging and/or maintaining 
general buildbot health (OK'ing modal crash dialogues on Windows, for 
example).


2.  Address the second problem of the buildbot web interface sucking for 
non-standard branches.  I'm thinking along the lines of a hack to 
buildbot, such that upon creation of new per-activity branches off a 
mainline, something magically runs in the background and sets up a 
complete buildbot view at 
python.snakebite.org/dev/buildbot/, just as if you 
were looking at a trunk buildbot page.


I'm not sure how easy the second point will be when we switch to hg; and 
I'll admit if there have been any python-dev discussions about buildbot 
once we're on hg, I've missed them.


Of course there's a third option, which is using the infrastructure I've 
mentioned to address a similarly annoying pain point I haven't thought 
of -- so feel free to mention anything else you'd like to see first 
instead of the above two things.


Titus, for example, alluded to some nifty way for a committer to push 
his local hg branch/changes somewhere, such that it would kick off 
builds on multiple platforms in the same sorta' vein as point 2, but 
able to leverage cloud resources like Amazon's EC2, not just Snakebite 
hardware.


Look forward to hearing some feedback!

Regards,

Trent.

This is a completely separate issue, though probably around just as
long, and like the popup problem its frequency changes over time.  By
"hung" here I'm referring to cases where something must go wrong with
a test and/or its cleanup such that a python_d process remains
running, usually several of them at the same time.


My guess: the "hung" (single-threaded) Python process has called 
select() without a timeout in order to wait for some data.  However, the 
data never arrives (due to a broken/failed test), and the select() never 
returns.


On Windows, processes seem harder to kill when they get into this state. 
 If I purposely wedge a Windows process via select() via the 
interactive interpreter, ctrl-c has absolutely no effect (whereas on 
Unix, ctrl-c will interrupt the select()).


As for why kill_python.exe doesn't seem to be able to kill said wedged 
processes, the MSDN documentation on TerminateProcess[1] states the 
following:


The terminated process cannot exit until all
pending I/O has been completed or canceled. (sic)

It's not unreasonable to assume a wedged select() constitutes pending 
I/O, so that's a possible explanation as to why kill_python.exe isn't 
able to terminate the processes.


(Also, kill_python currently assumes TerminateProcess() always works; 
perhaps this optimism is misplaced.  Also note the XXX TODO regarding 
the fact that we don't kill processes that have loaded our python*.dll, 
but may not be named python_d.exe.  I don't think that's the issue here, 
though.)

That's interesting.  (That kill_python.exe doesn't kill the wedged 
processes, but pskill does.)  kill_python is pretty simple, it just 
calls TerminateProcess() after acquiring a handle with the relevant 
PROCESS_TERMINATE access right.  That being said, that's the recommended 
way to kill a process -- I doubt pskill would be going about it any 
differently (although, it is sysinternals... you never know what kind of 
crazy black magic it's doing behind the scenes).


Are you calling pskill with the -t flag? i.e. kill process and all 
dependents?  That might be the ticket, especially if killing the child 
process that wedged select() is waiting on causes it to return, and 
thus, makes it killable.


Otherwise, if it happens again, can you try kill_python.exe first, then 
pskill, and confirm if the former fails but the latter succeeds?

[Python-Dev] Importing bsddb 4.6.21; with or without AES encryption?

2008-05-15 Thread Trent Nelson
I was about to commit an initial import of the bsddb 4.6.21 source to the 
'external' area in the repo, which I obtained from the following URL:


http://www.oracle.com/technology/software/products/berkeley-db/index.html

I downloaded the source that includes AES encryption, for no reason other than 
it was first on the list.  I'm now wondering if we should only be importing the 
'NC' source that doesn't contain any encryption?  Jesus, does pybsddb use any 
of the Berkeley DB encryption facilities?  Would anything break if we built the 
bsddb module without encryption?

(Note that all of this only applies to Windows.)

Yes, pybsddb3 4.6.4 supports cryptography if the underlying Berkeley DB
library is crypto enabled.

In principle, you can compile BDB without crypto, and pybsddb3 should
work, but you would lose ability to open any DB formerly created using
page encryption or page checksum.

Export laws aside, we better compile with crypto :).

Seems like the amount of work you have to do has doubled now that you've
been added as an svn committer, given that you're maintaining multiple
branches of code, one for pybsddb, and one for an official Python branch.
I was under the impression that pybsddb would be assimilated into trunk/
Lib/bsddb and become the sole pybsddb incarnation.  That is, you'd ditch
the separate SourceForge pybsddb project and just work directly in the
Python tree.

I think I remember reading some concerns you had about doing this last
week though, surrounding things like wanting to be able to release pybsddb
versions more frequently than Python versions are released.  Just because
you live in trunk/Lib/bsddb shouldn't prevent you from doing this though;
in fact, as long as you're sensitive to major release timeframes, I'm
sure we'd love trunk to always track the latest Berkeley DB version; if
all the buildbots stay green with 4.7 and there are no regressions in
functionality, then hey, lets go with 4.7 for 2.6/3.0.

It's probably safe to say that you're the one doing the most work with
the code base and Berkeley DB in general, which means you'll be in a much
better position to advise us as to which version we should be including or
ignoring for a given Python release.  In general, if we can support the
latest release, we will.

If Oracle come out with Berkeley DB 4.8 a week after 2.6 is released,
that's fine, we'll keep release26-maint chugging along with 4.7, but we
can switch trunk over to 4.8 once you're ready.  By the time it's ready
to cut 2.7, who knows, trunk's bsddb may be supporting Berkeley DB 5.2
at that stage.  I would also think that you could cut independent releases
(in the sense that they're not linked to any Python release schedule) of
'pybsddb' from the code living in trunk/Lib/bsddb.  That way, users of 2.6
could still easy_install (or whatever) the latest pybsddb 4.8.0 to pick up
the newest features.

Indeed.  Where do we stand with regards to svn commit e-mails being sent for

Oh my.  Just finished plugging 4.7.25 into the Windows build environment.  Upon 
running regrtest.py -v -u bsddb test_bsddb test_bsddb3, I get about 300 lines 
like this printed to stderr:

Re: [Python-Dev] BSDDB3

2008-05-29 Thread Trent Nelson
Thanks Jesus.  I'll import BSDDB 4.6.4 into svn.python.org/projects/external 
today.  Once that's done, I'll create a new bsddb46.vcproj and update the 
pcbuild.sln to use this project instead of the bsddb44 one currently being 
used.  (Hopefully I'll be able to get that done today as well.)

I assume you're just working on trunk at the moment?  i.e. should I block or 
merge the changes to py3k?

For everyone else: just a heads up that there will probably be a little bit of 
buildbot instability whilst we transition BSDDB versions on Windows.

Trent.

| Great!  Once you've settled in with your changes let me know and I'll
help with doing the necessary things on the Windows-side to set up the
bsddb46.vcproj and switching the build to use that.

Python SVN updated. Let me know if you need anything from me.

Re: [Python-Dev] Committing bsddb 4.6.4, and where can I put testsuite temp files?

2008-05-29 Thread Trent Nelson
Hi Jesus,

Regarding where to place test files, you might want to look at how the current 
bsddb test suite in Lib/bsddb/test handles the need to create temporary files 
and such.  A bit of work has gone into this particular aspect to improve 
reliability and robustness on buildbots -- particularily when it comes to 
Windows.  (I believe the current test suite comes up with a unique directory 
based on process ID..)

temp files?

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

I just committed pybsddb 4.6.4 to python svn. My next step (after a
successfull buildbot cycle, I hope!) is to commit the new testsuite.
First I need to review any changes there since I maintain pybsddb.

The testsuite creates a lot of files/directories while working. Fine,
since it cleans later, unless some test crashes hard. My testcode
defines a variable to the path I want to use to keep those files/dirs.
Currently it is "/tmp/z-BerkeleyDB", or something like that.

Since my code allows for testcases to be run in multiple threads and/or
processes, where would be a sensible path choice for temporal files?.
Current working directory would be fine, if "somebody" is cleaning after
running all tests.

Ramdisk ("/tmp" in some systems, for example Solaris) would be nice,
since some test uses transactions, and transactions are write-synchronous.

In my system, runnning all tests serially (you can run all of them in
parallel, if you wish) takes about 15-20 seconds. Far faster than
current tests in python svn, and that can be improved even more.

[Python-Dev] Importing bsddb 4.6.21; with or without AES encryption?

2008-05-29 Thread Trent Nelson
I was about to commit an initial import of the bsddb 4.6.21 source to the 
'external' area in the repo, which I obtained from the following URL:


http://www.oracle.com/technology/software/products/berkeley-db/index.html

I downloaded the source that includes AES encryption, for no reason other than 
it was first on the list.  I'm now wondering if we should only be importing the 
'NC' source that doesn't contain any encryption?  Jesus, does pybsddb use any 
of the Berkeley DB encryption facilities?  Would anything break if we built the 
bsddb module without encryption?

(Note that all of this only applies to Windows.)

Trent.

Re: [Python-Dev] Obtaining short file path

2008-06-09 Thread Trent Nelson
If you want a short path name, you should use win32api.GetShortPathName().  
Attempting to compute it yourself isn’t as straight forward as you think.

From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Hartwell Bryan
Sent: 27 May 2008 08:00
To: python-dev@python.org
Subject: [Python-Dev] Obtaining short file path


Hi,

Purpose: obtaining the system (“short”) path from a full path

Background: File dialogs (visual studio) return a full path (e.g. f=“C:\this 
path has spaces\thisfilenameislongerthan8char.txt”). If this value is provided 
to Python, it will not recongize this as a file. In fact os.path.isfile(f) 
doesn’t return false, it crashes. Likewise, when calling executables (from 
Python) with files as arguments a short path is required. VB FileSystemObject 
has the ShortPath method, while os.path and path (www.jorendorff.com) modules 
do not (at least as far as my googling could determine). Why bother creating a 
COM interface when you’re just going to pass as shell run-time arguments all 
the values the server is better at computing?

System: Python 2.3; Windows XP

Sample Code:

import win32com.client

import time

import os,sys

import os.path

#-

def shortpath(x):

  z=''

  for y in x.split('\\'):

if len(y.split('.')[0])>8:

  if ('.' in y):

z=z+'\\'+y.split('.')[0][:6].upper()+'~1'+'.'+y.split('.')[1]

  else:

z=z+'\\'+y[:6].upper()+'~1'

else:

  z=z+'\\'+y

  return z[1:]

#-

xlApp = win32com.client.Dispatch("Excel.Application")

xlBook = xlApp.ActiveWorkbook

savFile = str(sys.argv[1])

rawFile = str(xlBook.Sheets("Timestamp").TextBox2)

#print os.path.isfile(savFile)

r=shortpath(rawFile)

print r

try:

  print os.path.isfile(r)

except:

  print 'something rude'

time.sleep(7)

Notes: This code does not account for peer paths or files that share the first 
8 characters (and file extension). I’m also aware that this is not the normal 
means for submitting a “patch”, but in my job function I don’t see myself 
regularly participating in python development (and I’m probably not savvy 
enough) so the effort wasn’t worth it. However I still thought others might 
benefit from what seems to be (to me) a fundamental path function. Do with it, 
or ignore it, as you please.

Cheers,

Bryan Hartwell

[Python-Dev] Progress on switching Windows build to Berkeley DB 4.7.25...

2008-06-17 Thread Trent Nelson
Hi all,

Jesus, apologies that this has taken so long for me to get back to, I've been 
completely and utterly swamped with client work the past few weeks.  However, 
thanks to a couple of hours spare at Detroit airport yesterday, I was finally 
able to make some progress on updating the Windows Berkeley DB build to 4.7.25. 
 I've checked in the work I've done so far to 
branches/tnelson-trunk-bsddb-47-upgrade.  One thing I wanted to double check 
with you is the following change:

[Python-Dev] test_multiprocessing: test_listener_client flakiness

2008-06-18 Thread Trent Nelson
I gave my Windows buildbots a little bit of TLC last night.  This little 
chestnut in test_multiprocessing.py around line 1346 is causing my buildbots to 
wedge more often than not:

def test_listener_client(self):
for family in self.connection.families:
l = self.connection.Listener(family=family)
p = self.Process(target=self._test, args=(l.address,))
p.set_daemon(True)
p.start()
conn = l.accept()
self.assertEqual(conn.recv(), 'hello')
p.join()
l.close()

The wedging will be a result of that accept() call.  Not knowing anything about 
the module or the test suite, I can only assume that there's a race condition 
introduced between when the subprocess attempts to connect to the listener, 
versus when the l.accept() call is actually entered.  (On the basis that a race 
condition would explain why sometimes it wedges and sometimes it doesn't.)

Just FYI, the error in the buildbot log 
(http://www.python.org/dev/buildbot/all/x86%20W2k8%20trunk/builds/810/step-test/0)
 when this occurs is as follows:

test_multiprocessing

command timed out: 1200 seconds without output
SIGKILL failed to kill process
using fake rc=-1
program finished with exit code -1
remoteFailed: [Failure instance: Traceback from remote host -- Traceback (most 
recent call last):
Failure: buildbot.slave.commands.TimeoutError: SIGKILL failed to kill process
]

(The fact it can't be killed cleanly is a bug in Twisted's 
signalProcess('KILL') method, which doesn't work against Python processes that 
have entered accept() calls on Windows (which present the 'wedged' behaviour 
and have to be forcibly killed with OpenProcess/TerminateProcess).)
