Yum List Command

The parsers contains in this module are:

YumListInstalled - Command yum list installed

YumListAvailable - Command yum list available

class insights.parsers.yum_list.YumListAvailable(context)

Bases: YumListBase

The YumListAvailable class parses the output of the yum list available command. Each line is parsed and stored in a YumListRpm object.

Input and usage examples are identical to YumListInstalled but with “Installed” replaced with “Available” wherever applicable.

class insights.parsers.yum_list.YumListBase(context, package_status)

Bases: CommandParser, RpmList

Base class for the yum list [installed|available] commands. Each line is parsed and stored in a YumListRpm object.

Note

YumListBase shares the insights.parsers.installed_rpms.RpmList interface with insights.parsers.installed_rpms.InstalledRpms. The only difference is YumListBase takes the output of yum list as its source data, and the YumListRpm instances it produces contain a .repo attribute.

expired_cache

Indicates if the yum repo cache is expired.

Type:

bool

package_status

Indicates if the list is of installed or available packages.

Type:

str

parse_content(content)

yum list output is basically tabular with an ignorable set of rows at the top and a line “Installed Packages” that designates the following rows as data. Each column has a maximum width, and if any column overflows, the following columns wrap to the next line and indent to their usual starting positions. It’s also possible for the data rows to be followed by more lines that should be ignored. Since yum list is for human consumption, the footer lines can be syntactically ambiguous with data lines. We use heuristics to check for an invalid row to signal the end of data.

class insights.parsers.yum_list.YumListInstalled(context)

Bases: YumListBase

The YumListInstalled class parses the output of the yum list installed command. Each line is parsed and stored in a YumListRpm object.
