[IPython-dev] Reposting : an issue in replaying logs with profile

[Johann Cohen-Tanugi]

hello,
my problem below did not get addressed. Can someone help me understand 
what I am doing wrong?
thanks in advance,
Johann

-------------------
hi there,
I am using a very recent bazaar build of ipython and python 2.5. I have 
the following profile in my IPYTHONDIR:

[cohen at jarrett ~]$ more .ipython/ipy_profile_test.py
import IPython.ipapi
ip = IPython.ipapi.get()

ip.ex("print '*****************************************************'")
ip.ex("print '* TEST *'")
ip.ex("print '*****************************************************'")

ip.ex("import os")


I then run the following :
[cohen at jarrett ~]$ ipython -profile test -log
Activating auto-logging. Current session state plus future input saved.
Filename       : ipython_log.py
Mode           : rotate
Output logging : False
Raw input log  : False
Timestamping   : False
State          : active

IPython profile: test

In [1]: n=5.2

In [2]: os
Out[2]: <module 'os' from '/usr/lib/python2.5/os.pyc'>

after exiting the session, the log looks like :
[cohen at jarrett ~]$ more ipython_log.py
#log# Automatic Logger file. *** THIS MUST BE THE FIRST LINE ***
#log# DO NOT CHANGE THIS LINE OR THE TWO BELOW
#log# opts = Struct({'__allownew': True, 'log': 1, 'logfile': 
'ipython_log.py', 'profile': ''})
#log# args = []
#log# It is safe to make manual edits below here.
#log#----------------------------------------------------------------------- 

n=5.2
os

That does *not* look good because the 'profile' value is blank, and 
indeed :
[cohen at jarrett ~]$ ipython -logplay ipython_log.py
Activating auto-logging. Current session state plus future input saved.
Filename       : ipython_log.py
Mode           : append

State          : active

In [1]: os

NameError: name 'os' is not defined

There was no 'TEST' banner and no importing of os, as anticipated as the 
profile is not filled in the log.
Even more problematic :
[cohen at jarrett ~]$ ipython -profile test -logplay ipython_log.py
Activating auto-logging. Current session state plus future input saved.
Filename       : ipython_log.py

Here the -profile argument request is not even honored....
If I add test as the profile in the log file, then I get
the correct behavior in both cases :
[cohen at jarrett ~]$ ipython -logplay ipython_log.py
Activating auto-logging. Current session state plus future input saved.
Filename       : ipython_log.py

So to make a long story short : there is a faulty behavior of the logger 
that does not correctly save the profile used. I am trying to read the 
code (Logger.py and ipilib.py seem to be the natural candidates) but if 
someone finds the correct patch more quickly, I will be happy too :) .
cheers,
Johann
