translationmodules option failing
by pypy＠pocketnix.org April 12, 2011

April 12, 2011

Hi just tried to bootstrap myself in the quickest way possible via the --translationmodules option (cmdline below) and encountered an issue with the md5 module which appears to be renamed _md5. the patch below corrects this. while there was an md5 directory present in my tree it only contained untracked pyc files and as such i have also removed this ------------------------------------- ./translate.py -O jit --thread --make-jobs=9 ./targetpypystandalone.py --translationmodules ------------------------------------- --- a/pypy/config/pypyoption.py +++ b/pypy/config/pypyoption.py @@ -39,7 +39,7 @@ translation_modules = default_modules.copy() translation_modules.update(dict.fromkeys( ["fcntl", "rctime", "select", "signal", "_rawffi", "zlib", - "struct", "md5", "cStringIO", "array"])) + "struct", "_md5", "cStringIO", "array"])) -------------------------------------

File overwriting (--output flag to translate.py)
by pypy＠pocketnix.org April 12, 2011

April 12, 2011

Hi again i have been compiling a bunch of different pypy instances with different levels of optimizations and features and found that if i run pypy-c from the current directory and dont specify a new output filename it will attempt to and fail to overwrite pypy-c due to the file being "in use". unfortunately the exception generated is in the shutil lib from mem and the error message/exception does not give away immediately what the cause is which can lead to some frustration on some of the longer compiles ;) its quick and dirty and i don't mind if it gets changed at all. not 100% sure what the correct way to report an error and abandon is other than what everything else does (uncaught exception to a pdb shell) --- a/pypy/translator/goal/translate.py +++ b/pypy/translator/goal/translate.py @@ -285,6 +285,10 @@ elif drv.exe_name is None and '__name__' in targetspec_dic: drv.exe_name = targetspec_dic['__name__'] + '-%(backend)s' + # Ensure the file does not exisit else we fail at end of translation + if os.path.isfile(drv.exe_name): + raise ValueError('File "' + drv.exe_name+ '" already exisits (--output)') + goals = translateconfig.goals try: drv.proceed(goals)

Wasn't there also talk about having the sprint (or *a* >sprint) done before the conference? yes, I was hoping to catch Alex Gaynor for that, as he is attending EuroDjango earlier the same month. My point is that we need to decide what we are doing very, very soon. else everybody will have their plane tickets already, since we will have to announce what we are doing differently.

Waf benchmark
by Maciej Fijalkowski April 12, 2011

April 12, 2011

Hello. I propose the waf benchmark removal. Originally, the idea was that we're slower than CPython for no good reason. Now that this benchmark measures some obscure piece of stdlib time (subprocesses) I don't think it's that necessary. Besides: * the variation between runs is too big, so we don't care * noone was ever remotely interested in speeding this up any opinions? Cheers, fijal

2 days after the conference is not a lot of time. Do we want to rent some space to have a longer sprint? Or is it too late, people will already have booked their plane tickets, or ... Laura

Pre sprint beer session Sunday 24th of April
by Bea During April 11, 2011

April 11, 2011

( emailing this list since I was not allowed to post to pypy-sprint and people don´t seem to use it?) Hi there Since I am travelling to Japan on the 25th of April I will miss the Gothenburg sprint (that was not the original plan but my family had to move our trip because of what happened there). I still would like to meet up so I invite you to a pre sprint beer session at Bishops Arms pub in central Gothenburg, Sunday 24th of April, starting from 18:00. The Bishop Arms pub is a very nice, quiet pub (library inspired but cosy) and they have a good selection of beers and whiskey. Here is a map: http://www.bishopsarms.com/Goteborg_Park/Presentation This way I get to meet most of you - and drink beer! Talk about eating the cake and having it ;-) Cheers Bea p.s. Anto - will miss you there d.s
