Also, for ease of use, I think that the most likely usage should be as obvious as possible. The typical use of this feature should be to actually run the commands needed to setup the host for OE-lite development, and should be supported by something as simple as oe setup Listing supported host configuration/distros could be kept as oe setup -l And for printing out the commands could be kept as: oe setup -p but changed to print out in a format that can be piped directly into a shell, so something like this can be done: oe setup -p | /bin/sh Non-executable information like host configuration can be printed as '#' comment lines. > --- > lib/oelite/cmd/__init__.py | 2 +- > lib/oelite/cmd/hostprep.py | 132 +++++++++++++++++++++ > .../cmd/supported-host-configs/centos_6.4_final | 13 ++ > .../cmd/supported-host-configs/exherbo_none_none | 1 + > .../supported-host-configs/ubuntu_12.04_precise | 7 ++ > 5 files changed, 154 insertions(+), 1 deletion(-) > create mode 100644 lib/oelite/cmd/hostprep.py > create mode 100644 lib/oelite/cmd/supported-host-configs/centos_6.4_final > create mode 100644 lib/oelite/cmd/supported-host-configs/exherbo_none_none > create mode 100644 lib/oelite/cmd/supported-host-configs/ubuntu_12.04_precise > > diff --git a/lib/oelite/cmd/__init__.py b/lib/oelite/cmd/__init__.py > index d2feabe..6919262 100644 > --- a/lib/oelite/cmd/__init__.py > +++ b/lib/oelite/cmd/__init__.py > @@ -1 +1 @@ > -manifest_cmds = [ "bake", "show", "cherry" ] > +manifest_cmds = [ "bake", "hostprep","show", "cherry" ] > diff --git a/lib/oelite/cmd/hostprep.py b/lib/oelite/cmd/hostprep.py > new file mode 100644 > index 0000000..ae82fd8 > --- /dev/null > +++ b/lib/oelite/cmd/hostprep.py > @@ -0,0 +1,132 @@ > +import oebakery > +from oelite import util > +import logging > +import os > +import subprocess > +import oelite > + > +description = "Host preparation tool" > +arguments = () > + > +def add_parser_options(parser): > + parser.add_option("-c", "--command", > + action="store_true", default=False, > + help="Show the command needed to prepare the > host for OE-lite") Change to '-p', '--print' > + parser.add_option("-l", "--list-supported-host-configs", Maybe choose a slightly shorter long options, fx. just '--list'. > + action="store_true", default=False, > + help="Show a list of known host configurations") > + parser.add_option("-s", "--select-host-config", Again, a shorter long option like '--host' is preferable.

You should be able to use bb.utils.which() to find files and/or dirs in all layers. To search for a specific host config file, use something like this: bb.utils.which(d.get('OEPATH'), 'setup/debian_7.1') or to search for all 'setup/' dirs: bb.utils.which(d.get('OEPATH'), 'setup') > + hid = 0 > + hc=[] > + config_dir = "./meta/core/lib/oelite/cmd/supported-host-configs" > + logging.debug("Using config directory: %s", config_dir) > + for config in os.listdir(config_dir): > + logging.debug("Reading config: %s", config) > + keys = config.split('_') > + if(len(keys) != 3): > + logging.debug("Ignoring host-config with wrong name: %s", config) > + continue > + #read out the cmd to run for this host configuration > + try: > + logging.debug("Read the host preparation command") > + #strip off the last newline > + cmd = open(config_dir+"/"+config, 'r').read()[:-1] > + except: > + logging.debug("Reading the host preparation command from the host configuration file failed") > + raise > + hc.append(dict(distro=keys[0], release=keys[1], > codename=keys[2], hostID=hid, command=cmd)) Any special reason to use both distro, release and codename?

Instead, when auto-detecting or when looking for a specified host configuration, you should just search for the setup file using bb.util.which(). And while we are at the searching topic, we probably need to have some major/minor version search logic. In my case, I have Debian 7.1 installed. We should probably search for 'debian_7.1' first, and if not found, try 'debian_7' next, and then 'debian', and finally 'unknown'. > + > +def determine_host(host_configs): > + logging.debug("Running host detection") > + logging.debug("Searching for lsb_release information") > + #try lsb-release which is the most widely available method > + if(os.path.exists("/etc/lsb-release") and os.path.isfile("/etc/lsb-release")): Why look for the /etc/lsb-release file?

Also, the output claims to print out "List of supported host configurations", and includes "unknown"... Perhaps just change the description to "List of known host configurations" or something better. Also, it might be convenient to have a way of storing information about known unsupported host distros. So if we know that Ubuntu 8.04 will not work, or at least that we know that our guidelines are not sufficient to make it work, we should have a host configuration/setup file encode this information.

If we want that we need to be really sure we detected the correct host configuration. I (also as a user) would prefer to run any commands myself, but just be told what to do, then I can inspect it. My idea of printing out the detected host configuration would be to avoid problems of being "too clever", guess that could also be done by prompting for a user reply like when we run "oe bake" ? > > Listing supported host configuration/distros could be kept as > > oe setup -l > > And for printing out the commands could be kept as: > > oe setup -p > > but changed to print out in a format that can be piped directly into a > shell, so something like this can be done: > > oe setup -p | /bin/sh > > Non-executable information like host configuration can be printed as '#' > comment lines. sure, makes sense > >> --- >> lib/oelite/cmd/__init__.py | 2 +- >> lib/oelite/cmd/hostprep.py | 132 +++++++++++++++++++++ >> .../cmd/supported-host-configs/centos_6.4_final | 13 ++ >> .../cmd/supported-host-configs/exherbo_none_none | 1 + >> .../supported-host-configs/ubuntu_12.04_precise | 7 ++ >> 5 files changed, 154 insertions(+), 1 deletion(-) >> create mode 100644 lib/oelite/cmd/hostprep.py >> create mode 100644 lib/oelite/cmd/supported-host-configs/centos_6.4_final >> create mode 100644 lib/oelite/cmd/supported-host-configs/exherbo_none_none >> create mode 100644 lib/oelite/cmd/supported-host-configs/ubuntu_12.04_precise >> >> diff --git a/lib/oelite/cmd/__init__.py b/lib/oelite/cmd/__init__.py >> index d2feabe..6919262 100644 >> --- a/lib/oelite/cmd/__init__.py >> +++ b/lib/oelite/cmd/__init__.py >> @@ -1 +1 @@ >> -manifest_cmds = [ "bake", "show", "cherry" ] >> +manifest_cmds = [ "bake", "hostprep","show", "cherry" ] >> diff --git a/lib/oelite/cmd/hostprep.py b/lib/oelite/cmd/hostprep.py >> new file mode 100644 >> index 0000000..ae82fd8 >> --- /dev/null >> +++ b/lib/oelite/cmd/hostprep.py >> @@ -0,0 +1,132 @@ >> +import oebakery >> +from oelite import util >> +import logging >> +import os >> +import subprocess >> +import oelite >> + >> +description = "Host preparation tool" >> +arguments = () >> + >> +def add_parser_options(parser): >> + parser.add_option("-c", "--command", >> + action="store_true", default=False, >> + help="Show the command needed to prepare the >> host for OE-lite") > Change to '-p', '--print' ok > >> + parser.add_option("-l", "--list-supported-host-configs", > Maybe choose a slightly shorter long options, fx. just '--list'. ok > >> + action="store_true", default=False, >> + help="Show a list of known host configurations") >> + parser.add_option("-s", "--select-host-config", > Again, a shorter long option like '--host' is preferable.

I (also as a user) would prefer to run any commands > myself, but just be told what to do, then I can inspect it. Good point. But at the same time, we want to make it as convenient and straight-forward to do the most simple and usual tasks. Perhaps making "oe setup" print out to console what it is to be executed, and ask the user to confim with 'yes/no' (default to no, and require to type 'yes' and not just 'y'), and then add a '-y' option to skip that and just execute the command(s). When running "oe setup" without '-y', you could even check if it is actually a tty, and if not, just revert to do the same as if '-p' was given. > My idea of printing out the detected host configuration would be to avoid > problems of being "too clever", guess that could also be done by prompting for > a user reply like when we run "oe bake" ? Yes, and there we also provide the '-y' :) But, it differs in a couple of ways. It is quite common end in situations where "oe bake" wants to build more than you wanted, and thus you often end up answering 'no', and then doing some kind of '--sloppy' bake instead. For "oe setup", _if_ we provide a reliable host distro detection system, most (if not all) users will want to answer 'yes'. Running "oe bake" is something you do all the time when working with OE-lite, while "oe setup" should be very rare. Running "oe setup" changes your host OS, where "oe bake" only changes your OE-lite tmp dir. The last two differences points into the direction of requiring user confirmation, where the first points in the opposite direction. So overall, it is probably best to not just execute the command(s), but an '-y'/'--yes' option should be supported. > Listing supported host configuration/distros could be kept as > > oe setup -l > > And for printing out the commands could be kept as: > > oe setup -p > > but changed to print out in a format that can be piped directly into a > shell, so something like this can be done: > > oe setup -p | /bin/sh > > Non-executable information like host configuration can be printed as '#' > comment lines. > > sure, makes sense > > > > --- > lib/oelite/cmd/__init__.py | 2 +- > lib/oelite/cmd/hostprep.py | 132 +++++++++++++++++++++ > .../cmd/supported-host-configs/centos_6.4_final | 13 ++ > .../cmd/supported-host-configs/exherbo_none_none | 1 + > .../supported-host-configs/ubuntu_12.04_precise | 7 ++ > 5 files changed, 154 insertions(+), 1 deletion(-) > create mode 100644 lib/oelite/cmd/hostprep.py > create mode 100644 lib/oelite/cmd/supported-host-configs/centos_6.4_final > create mode 100644 lib/oelite/cmd/supported-host-configs/exherbo_none_none > create mode 100644 lib/oelite/cmd/supported-host-configs/ubuntu_12.04_precise > > diff --git a/lib/oelite/cmd/__init__.py b/lib/oelite/cmd/__init__.py > index d2feabe..6919262 100644 > --- a/lib/oelite/cmd/__init__.py > +++ b/lib/oelite/cmd/__init__.py > @@ -1 +1 @@ > -manifest_cmds = [ "bake", "show", "cherry" ] > +manifest_cmds = [ "bake", "hostprep","show", "cherry" ] > diff --git a/lib/oelite/cmd/hostprep.py b/lib/oelite/cmd/hostprep.py > new file mode 100644 > index 0000000..ae82fd8 > --- /dev/null > +++ b/lib/oelite/cmd/hostprep.py > @@ -0,0 +1,132 @@ > +import oebakery > +from oelite import util > +import logging > +import os > +import subprocess > +import oelite > + > +description = "Host preparation tool" > +arguments = () > + > +def add_parser_options(parser): > + parser.add_option("-c", "--command", > + action="store_true", default=False, > + help="Show the command needed to prepare the > host for OE-lite") > > Change to '-p', '--print' > > ok > > > > + parser.add_option("-l", "--list-supported-host-configs", > > Maybe choose a slightly shorter long options, fx. just '--list'. > > ok > > > > + action="store_true", default=False, > + help="Show a list of known host configurations") > + parser.add_option("-s", "--select-host-config", > > Again, a shorter long option like '--host' is preferable.

But sure we can > change that It might not matter, but I think the code will be smaller and more clear if you do it that way. It is quite simple to use the bb.utils.which() command to search for the host configuration, and you don't have to care about inventing hostID or something like that and implementing a search loop (not that it is complicated, but less code is often better). > And while we are at the searching topic, we probably need to have some > major/minor version search logic. > > In my case, I have Debian 7.1 installed.

It might be, but in this case, you really don't want to do things different for 7.1 than for 7.0. And, if we do this in the strict way, an old OE-lite manifest is almost guaranteed to not work out of the box in the future, as releases such as Debian will have bumbed their minor versions. And this is opposite of what we try to achieve. Of-course, you probably do not want to have a 'debian' host configuration available, but there might be other cases where a version independent host configuration might make sense (rolling-release like exherbo springs to mind...) > + > +def determine_host(host_configs): > + logging.debug("Running host detection") > + logging.debug("Searching for lsb_release information") > + #try lsb-release which is the most widely available method > + if(os.path.exists("/etc/lsb-release") and os.path.isfile("/etc/lsb-release")): > > Why look for the /etc/lsb-release file?

My Debian 7.1 install does not have the /etc/lsb-release file, but does have the lsb_release command. Because of the missing /etc/lsb-release I get: ~ $ lsb_release -v No LSB modules are available.

From: Kim Højgaard-Hansen <kiho@prevas.dk> The hostprep command can show what command is needed to prepare the host for OE-lite. A file for each supported host configuration must be added to th supported-host-configs directory. The file should contain the command needed to install the dependencies needed for using oe-lite. The file name should be: distro_release_codename as defined by lsb_release. The lsb_release tool is used for automatic host detection. A list of the supported host configurations can be shown by passing -l to the hostprep command. If only the preparation command for the current host should be shown, run 'hostprep -c' --- lib/oelite/cmd/__init__.py | 2 +- lib/oelite/cmd/hostprep.py | 132 +++++++++++++++++++++ .../cmd/supported-host-configs/centos_6.4_final | 13 ++ .../cmd/supported-host-configs/exherbo_none_none | 1 + .../supported-host-configs/ubuntu_12.04_precise | 7 ++ 5 files changed, 154 insertions(+), 1 deletion(-) create mode 100644 lib/oelite/cmd/hostprep.py create mode 100644 lib/oelite/cmd/supported-host-configs/centos_6.4_final create mode 100644 lib/oelite/cmd/supported-host-configs/exherbo_none_none create mode 100644 lib/oelite/cmd/supported-host-configs/ubuntu_12.04_precise
