Odd message while building Python from tip
I don't think I've ever seen this message before. This is just after 'hg pull -u' to get to the latest CPython (my previous build was about a month ago). 'make' succeeded, but concluded with this message: running build_ext The following modules found by detect_modules() in setup.py, have been built by the Makefile instead, as configured by the Setup files: atexitpwd time And then proceeded to run build_scripts as normal. It doesn't look like an error, and those three modules can happily be imported by "./python" and by the freshly-installed "python3.7". It's curious though. Any explanation?

Using python to start programs after logging in
I am writing a python program to start the programs that need to be
started after logging in.
I have the following imports:
from subprocess import check_call, Popen, STDOUT
from time import sleep, strftime
And use the following code:
check_call(tuple('wmctrl -s 10'.split()))
log_file = open('Logging/firefox_%T.log'.replace('%T', strftime('%F_%R')),
'w')
Popen(tuple('firefox'.split()), stdout = log_file, stderr = STDOUT)
The first statement is to go to the correct desktop.
Is this a good way to do things, or could I do it in a better way?

Apart from the other answer, your use of .replace is odd. This would be
better:
log_file = open('Logging/firefox_%s.log' % strftime('%F_%R'), 'w')
Even better would be to use the 'with' statement as well.

Why are you using Python instead? Because when you use the window managers builtin facilities then all programs will be started on the same virtual desktop and I want to start them on different ones. Second reason is that I want to fetch the programs to start from a database so I can easily change the programs to be started. -- Cecil Westerhof Senior Software Engineer LinkedIn: http://www.linkedin.com/in/cecilwesterhof -- https://mail.python.org/mailman/listinfo/python-list

The reason is that it is ‘generic’ code. In the future instead of
string it will be a variable and only when the variable contains %T it
should be replaced.

The same here. Not always has the output to be logged and then I would
use NONE for log_file.

Re: Odd message while building Python from tip
Hi, Chris.
They are "builtin" module.
python executable contains the modules already.
But I don't know it's safe to remove them from setup.py.
There are so many platforms and special build of Python.

I wrote a function for switching to the correct virtual desktop and
starting all the commands. I am also using with now:
def do_desktop(desktop, commands, seconds_to_wait = 10):
desktop_command = ('wmctrl -s ' + desktop).split()
check_call(tuple(desktop_command))
for command_arr in commands:
command = command_arr[0].split()
log_directory = command_arr[1]
directory = command_arr[2]
if (directory != ''):
chdir(directory)
if (log_directory == 'NONE'):
Popen(tuple(command.split()))
else:
log_file_name = log_directory.replace('%T', strftime('%F_%R'))
with open(log_file_name, 'w') as log_file:
Popen(tuple(command), stdout = log_file, stderr = STDOUT)
if (directory != ''):
set_default_dir()
sleep(seconds_to_wait)
The function set_default_dir:
def set_default_dir():
chdir(expanduser('~'))
The example with firefox is then done with:
commands = [
['firefox', 'Logging/firefox_%T.log', ''],
]
do_desktop('10', commands, 30)
Sometimes a command needs to be executed in a different directory,
that is done like:
commands = [
['lein run',
'NONE', 'Clojure/Quotes'],
['xfce4-terminal --maximize --execute screen -S Clojure -c
~/.screenrcClojure', 'NONE', ''],
]
do_desktop('6', commands, 30)

Something has changed between the last time you ran IPython and now. You have deleted something, changed something, installed something... or you have file system corruption and files are disappearing... or your PYTHONPATH environment variable is not set, or is set differently to the way it used to be... Do you want to investigate why the error occurred, or just fix it in the most convenient and easy way? If the second, then you can probably fix it by running: python2 -m pip install path assuming that you trust that path is a legitimate module. Looking at the traceback, I see the final call which fails is in a module called pickleshare.py: File "/usr/lib/python2.7/site-packages/pickleshare.py", line 40, in from path import path as Path You could try removing pickleshare and re-installing, or upgrading to the latest version, and see whether it brings in the "path" dependency. You could try running "locate path.py | grep python2.7" in the shell and see whether path is installed. If it is installed, it sounds like the PYTHONPATH is messed up. Run these and tell us what they say: locate path.py | grep python2.7 python2.7 -c "import sys; print sys.path" echo $PYTHONPATH Googling for your error gives me these two relevant looking hits: https://duckduckgo.com/html/?q=%22ImportError:%20No%20module%20named%20path%22+ipython https://github.com/jupyter/notebook/issues/270 https://github.com/jupyter/notebook/issues/525 -- Steve “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse. -- https://mail.python.org/mailman/listinfo/python-list

I am writing a python program to start the programs that need to

The first statement is to go to the correct desktop.
Is this a good way to do things, or could I do it in a better way?
Apart from the other answer, your use of .replace is odd. This
would be better:
log_file = open('Logging/firefox_%s.log' % strftime('%F_%R'), 'w')
The reason is that it is ‘generic’ code. In the future instead of
string it will be a variable and only when the variable contains %T
it should be replaced.
Even better would be to use the 'with' statement as well.
The same here. Not always has the output to be logged and then I
would use NONE for log_file.
I wrote a function for switching to the correct virtual desktop and
starting all the commands. I am also using with now:
def do_desktop(desktop, commands, seconds_to_wait = 10):
desktop_command = ('wmctrl -s ' + desktop).split()
check_call(tuple(desktop_command))
You don't have to pass a tuple to check_call; it'll also accept a list.
for command_arr in commands:
command = command_arr[0].split()
log_directory = command_arr[1]
directory = command_arr[2]
if (directory != ''):
chdir(directory)
There's no need for the parentheses around the 'if' condition.
if (log_directory == 'NONE'):
Popen(tuple(command.split()))
else:
log_file_name = log_directory.replace('%T', strftime('%F_%R'))
with open(log_file_name, 'w') as log_file:
Popen(tuple(command), stdout = log_file, stderr = STDOUT)
if (directory != ''):
set_default_dir()
Using 'chdir' is generally a bad idea.
'Popen' will start the process and then continue, so what you're doing
is changing the directory, starting a process, and then changing the
directory again, possibly before the process has truly started (i.e.
you've told the OS to start it, but there might be a small delay before
that happens). Popen accepts a 'cwd' argument, which sets the 'current
working directory' for that process.
sleep(seconds_to_wait)
The function set_default_dir:
def set_default_dir():
chdir(expanduser('~'))
The example with firefox is then done with:
commands = [
['firefox', 'Logging/firefox_%T.log', ''],
]
do_desktop('10', commands, 30)
Sometimes a command needs to be executed in a different directory,
that is done like:
commands = [
['lein run',
'NONE', 'Clojure/Quotes'],
['xfce4-terminal --maximize --execute screen -S Clojure -c
~/.screenrcClojure', 'NONE', ''],
]
do_desktop('6', commands, 30)
Why 'NONE'? Why not None?

I wrote a little better version:
def do_desktop(desktop, commands, seconds_to_wait):
desktop_command = (switch_desktop + desktop).split()
if seconds_to_wait == 0:
seconds_to_wait = 10
check_call(desktop_command)
for command_arr in commands:
command = command_arr[0].split()
log_directory = command_arr[1]
directory = command_arr[2]
if not log_directory:
log_directory = '/dev/null'
log_file_name = log_directory.replace('%T', strftime('%F_%R'))
with open(log_file_name, 'w') as log_file:
Popen(command, stdout = log_file, cwd = directory, stderr = STDOUT)
sleep(seconds_to_wait)
When there is no log_directory I set it to '/dev/null': that makes the
code a little bit cleaner.
And everything is now fetched from the database:
for desktop in cursor.execute(select_desktops).fetchall():
desktop_name= desktop[0]
desktop_value = desktop[1]
desktop_wait= desktop[2]
commands= cursor.execute(select_commands, [desktop_name]).fetchall()
do_desktop(desktop_value, commands, desktop_wait)
