Execute an external command and return the line output of the command in real-time.

This method assumes that there is a reasonably low delay between the end of output and the process exiting. If the child process closes stdout and then keeps on truckin’ there will be problems.

NOTE/WARNING: UnicodeDecodeError will be raised if the output of the
external command can’t be decoded as UTF-8.
Parameters:
  • command – The command to run
  • argv – The argument list
  • stdin – The file object to read stdin from.
  • stdout – Optional file object to redirect stdout and stderr to.
  • root – The directory to chroot to before running command.
  • env_prune – environment variable to remove before execution
  • filter_stderr – Whether stderr should be excluded from the returned output
  • callback – method to call while waiting for process to finish, passed Popen object
  • env_add – environment variables to add before execution
  • reset_handlers – whether to reset to SIG_DFL any signal handlers set to SIG_IGN
  • reset_lang – whether to set the locale of the child process to C
Returns:

Iterator of the lines from the command

Output from the file is not logged to program.log This returns an iterator with the lines from the command until it has finished

pylorax.ltmpl module

class pylorax.ltmpl.LoraxTemplate(directories=None)[source]

Bases: builtins.object

parse(template_file, variables)[source]
class pylorax.ltmpl.LoraxTemplateRunner(inroot, outroot, dbo=None, fatalerrors=True, templatedir=None, defaults=None)[source]

Bases: builtins.object

This class parses and executes Lorax templates. Sample usage:

# install a bunch of packages runner = LoraxTemplateRunner(inroot=rundir, outroot=rundir, dbo=dnf_obj) runner.run(“install-packages.ltmpl”)

# modify a runtime dir runner = LoraxTemplateRunner(inroot=rundir, outroot=newrun) runner.run(“runtime-transmogrify.ltmpl”)

NOTES:

  • Parsing procedure is roughly: 1. Mako template expansion (on the whole file) 2. For each line of the result,

    1. Whitespace splitting (using shlex.split())
    2. Brace expansion (using brace_expand())
    3. If the first token is the name of a function, call that function with the rest of the line as arguments
  • Parsing and execution are separate passes - so you can’t use the result of a command in an %if statement (or any other control statements)!

  • Commands that run external programs (systemctl, gconfset) currently use the host‘s copy of that program, which may cause problems if there’s a big enough difference between the host and the image you’re modifying.

  • The commands are not executed under a real chroot, so absolute symlinks will point outside the inroot/outroot. Be careful with symlinks!

ADDING NEW COMMANDS:

  • Each template command is just a method of the LoraxTemplateRunner object - so adding a new command is as easy as adding a new function.
  • Each function gets arguments that correspond to the rest of the tokens on that line (after word splitting and brace expansion)
  • Commands should raise exceptions for errors - don’t use sys.exit()
append(filename, data)[source]
append FILE STRING

Append STRING (followed by a newline character) to FILE. Python character escape sequences (‘n’, ‘t’, etc.) will be converted to the appropriate characters. Examples:

append /etc/depmod.d/dd.conf “search updates built-in” append /etc/resolv.conf “”
chmod(fileglob, mode)[source]
chmod FILEGLOB OCTALMODE
Change the mode of all the files matching FILEGLOB to OCTALMODE.

gconfset /apps/metacity/general/num_workspaces int 1
hardlink SRC DEST
Create a hardlink at DEST which is linked to SRC.
install(srcglob, dest)[source]
install SRC DEST

Copy the given file (or files, if a glob is used) from the input tree to the given destination in the output tree. The path to DEST must exist in the output tree. If DEST is a directory, SRC will be copied into that directory. If DEST doesn’t exist, SRC will be copied to a file with that name, assuming the rest of the path exists. This is pretty much like how the ‘cp’ command works. Examples:

install usr/share/myconfig/grub.conf /boot install /usr/share/myconfig/grub.conf.in /boot/grub.conf
installimg(srcdir, destfile)[source]
installimg SRCDIR DESTFILE

Create a compressed cpio archive of the contents of SRCDIR and place it in DESTFILE.

removefrom PKGGLOB [–allbut] FILEGLOB [FILEGLOB...]

Remove all files matching the given file globs from the package (or packages) named. If ‘–allbut’ is used, all the files from the given package(s) will be removed except the ones which match the file globs. Examples:

removefrom usbutils /usr/bin/* removefrom xfsprogs –allbut /sbin/*
removekmod(*globs)[source]
removekmod GLOB [GLOB...] [–allbut] KEEPGLOB [KEEPGLOB...]

Remove all files and directories matching the given file globs from the kernel modules directory.

If ‘–allbut’ is used, all the files from the modules will be removed except the ones which match the file globs. There must be at least one initial GLOB to search and one KEEPGLOB to keep. The KEEPGLOB is expanded to be KEEPGLOB so that it will match anywhere in the path.

This only removes files from under /lib/modules/*/kernel/

Examples:
removekmod sound drivers/media drivers/hwmon drivers/video removekmod drivers/char –allbut virtio_console hw_random
removepkg(*pkgs)[source]
removepkg PKGGLOB [PKGGLOB...]

Delete the named package(s). IMPLEMENTATION NOTES:

RPM scriptlets (%preun/%postun) are not run. Files are deleted, but directories are left behind.
replace(pat, repl, *fileglobs)[source]
replace PATTERN REPLACEMENT FILEGLOB [FILEGLOB ...]

Find-and-replace the given PATTERN (Python-style regex) with the given REPLACEMENT string for each of the files listed. Example:

replace @VERSION@ ${product.version} /boot/grub.conf /boot/isolinux.cfg

NOTE: All paths given MUST be COMPLETE, ABSOLUTE PATHS to the file or files mentioned. ${root}/${inroot}/${outroot} are good for constructing these paths.

FURTHER NOTE: Please use this command only as a last resort! Whenever possible, you should use the existing template commands. If the existing commands don’t do what you need, fix them!

Examples:

(this should be replaced with a “find” function) runcmd find ${root} -name “.pyo” -type f -delete %for f in find(root, name=”.pyo”):

remove ${f}

%endfor
