Function Details [hide private]

_ExtractTagsObject(opts, args)

source code 

Extract the tag type object.

Note that this function will modify its args parameter.

_ExtendTags(opts, args)

source code 

Extend the args if a source file has been given.

This function will extend the tags with the contents of the file passed in the 'tags_source' attribute of the opts parameter. A file named '-' will be replaced by stdin.

ListTags(opts, args)

source code 

List the tags on a given object.

This is a generic implementation that knows how to deal with all three cases of tag objects (cluster, node, instance). The opts argument is expected to contain a tag_type field denoting what object type we work on.

AddTags(opts, args)

source code 

Add tags on a given object.

This is a generic implementation that knows how to deal with all three cases of tag objects (cluster, node, instance). The opts argument is expected to contain a tag_type field denoting what object type we work on.

RemoveTags(opts, args)

source code 

Remove tags from a given object.

This is a generic implementation that knows how to deal with all three cases of tag objects (cluster, node, instance). The opts argument is expected to contain a tag_type field denoting what object type we work on.

_SplitKeyVal(opt, data)

source code 

Convert a KeyVal string into a dict.

This function will convert a key=val[,...] string into a dict. Empty values will be converted specially: keys which have the prefix 'no_' will have the value=False and the prefix stripped, the others will have value=True.

Parameters:
  • opt (string) - a string holding the option name for which we process the data, used in building error messages
  • data (string) - a string of the format key=val,key=val,...
Returns: dict
{key=val, key=val}
Raises:

check_ident_key_val(option, opt, value)

source code 

Custom parser for ident:key=val,key=val options.

This will store the parsed values as a tuple (ident, {key: val}). As such, multiple uses of this option via action=append is possible.

check_key_val(option, opt, value)

source code 

Custom parser class for key=val,key=val options.

This will store the parsed values as a dict {key: val}.

check_bool(option, opt, value)

source code 

Custom parser for yes/no options.

This will store the parsed value as either True or False.

_ParseArgs(argv, commands, aliases)

source code 

Parser for the command line arguments.

This function parses the arguments and returns the function which must be executed together with its (modified) arguments.

Parameters:
  • argv - the command line
  • commands - dictionary with special contents, see the design doc for cmdline handling
  • aliases - dictionary with command aliases {'alias': 'target, ...}

_CheckArguments(cmd, args_def, args)

source code 

Verifies the arguments using the argument definition.

Algorithm:

  1. Abort with error if values specified by user but none expected.
  1. For each argument in definition
    1. Keep running count of minimum number of values (min_count)
    1. Keep running count of maximum number of values (max_count)
    1. If it has an unlimited number of values
      1. Abort with error if it's not the last argument in the definition
  1. If last argument has limited number of values
    1. Abort with error if number of values doesn't match or is too large
  1. Abort with error if user didn't pass enough values (min_count)

CalculateOSNames(os_name, os_variants)

source code 

Calculates all the names an OS can be called, according to its variants.

Parameters:
  • os_name (string) - base name of the os
  • os_variants (list or None) - list of supported variants
Returns: list
list of valid names

ParseFields(selected, default)

source code 

Parses the values of "--field"-like options.

Parameters:
  • selected (string or None) - User-selected options
  • default (list) - Default fields

UsesRPC(fn)

source code 

RPC-wrapper decorator.

When applied to a function, it runs it with the RPC system initialized, and it shutsdown the system afterwards. This means the function must be called without RPC being initialized.

AskUser(text, choices=None)

source code 

Ask the user a question.

Parameters:
  • text - the question to ask
  • choices - list with elements tuples (input_char, return_value, description); if not given, it will default to: [('y', True, 'Perform the operation'), ('n', False, 'Do no do the operation')]; note that the '?' char is reserved for help
Returns:
one of the return values from the choices list; if input is not possible (i.e. not running with a tty, we return the last entry from the list

SendJob(ops, cl=None)

source code 

Function to submit an opcode without waiting for the results.

Parameters:
  • ops (list) - list of opcodes
  • cl (luxi.Client) - the luxi client to use for communicating with the master; if None, a new client will be created

GenericPollJob(job_id, cbs, report_cbs)

source code 

Generic job-polling function.

Parameters:

PollJob(job_id, cl=None, feedback_fn=None, reporter=None)

source code 

Function to poll for the result of a job.

Parameters:
  • job_id (job identified) - the job to poll for results
  • cl (luxi.Client) - the luxi client to use for communicating with the master; if None, a new client will be created

SubmitOpCode(op, cl=None, feedback_fn=None, opts=None, reporter=None)

source code 

Legacy function to submit an opcode.

This is just a simple wrapper over the construction of the processor instance. It should be extended to better handle feedback and interaction functions.

SubmitOrSend(op, opts, cl=None, feedback_fn=None)

source code 

Wrapper around SubmitOpCode or SendJob.

This function will decide, based on the 'opts' parameter, whether to submit and wait for the result of the opcode (and return it), or whether to just send the job and print its identifier. It is used in order to simplify the implementation of the '--submit' option.

It will also process the opcodes if we're sending the via SendJob (otherwise SubmitOpCode does it).

SetGenericOpcodeOpts(opcode_list, options)

source code 

Processor for generic options.

This function updates the given opcodes based on generic command line options (like debug, dry-run, etc.).

Parameters:
  • opcode_list - list of opcodes
  • options - command line options or None
Returns:
None (in-place modification)

FormatError(err)

source code 

Return a formatted error message for a given error.

This function takes an exception instance and returns a tuple consisting of two values: first, the recommended exit code, and second, a string describing the error message (not newline-terminated).

GenericMain(commands, override=None, aliases=None)

source code 

Generic main function for all the gnt-* commands.

Arguments:

  • commands: a dictionary with a special structure, see the design doc for command line handling.
  • override: if not None, we expect a dictionary with keys that will override command line options; this can be used to pass options from the scripts to generic functions
  • aliases: dictionary with command aliases {'alias': 'target, ...}

GenericInstanceCreate(mode, opts, args)

source code 

Add an instance to the cluster via either creation or import.

Parameters:
  • mode - constants.INSTANCE_CREATE or constants.INSTANCE_IMPORT
  • opts - the command line options selected by the user
  • args (list) - should contain only one element, the new instance name
Returns: int
the desired exit code

RunWhileClusterStopped(feedback_fn, fn, *args)

source code 

Calls a function while all cluster daemons are stopped.

Parameters:
  • feedback_fn (callable) - Feedback function
  • fn (callable) - Function to be called when daemons are stopped

GenerateTable(headers, fields, separator, data, numfields=None, unitfields=None, units=None)

source code 

Prints a table with headers and different fields.

Parameters:
  • headers (dict) - dictionary mapping field names to headers for the table
  • fields (list) - the field names corresponding to each row in the data field
  • separator - the separator to be used; if this is None, the default 'smart' algorithm is used which computes optimal field width, otherwise just the separator is used between each field
  • data (list) - a list of lists, each sublist being one row to be output
  • numfields (list) - a list with the fields that hold numeric values and thus should be right-aligned
  • unitfields (list) - a list with the fields that hold numeric values that should be formatted with the units field
  • units (string or None) - the units we should use for formatting, or None for automatic choice (human-readable for non-separator usage, otherwise megabytes); this is a one-letter string

FormatTimestamp(ts)

source code 

Formats a given timestamp.

Parameters:
  • ts (timestamp) - a timeval-type timestamp, a tuple of seconds and microseconds
Returns: string
a string with the formatted timestamp

ParseTimespec(value)

source code 

Parse a time specification.

The following suffixed will be recognized:

  • s: seconds
  • m: minutes
  • h: hours
  • d: day
  • w: weeks

Without any suffix, the value will be taken to be in seconds.

GetOnlineNodes(nodes, cl=None, nowarn=False, secondary_ips=False, filter_master=False)

source code 

Returns the names of online nodes.

This function will also log a warning on stderr with the names of the online nodes.

Parameters:
  • nodes - if not empty, use only this subset of nodes (minus the offline ones)
  • cl - if not None, luxi client to use
  • nowarn (boolean) - by default, this function will output a note with the offline nodes that are skipped; if this parameter is True the note is not displayed
  • secondary_ips (boolean) - if True, return the secondary IPs instead of the names, useful for doing network traffic over the replication interface (if any)
  • filter_master (boolean) - if True, do not return the master node in the list (useful in coordination with secondary_ips where we cannot check our node name against the list)

_ToStream(stream, txt, *args)

source code 

Write a message to a stream, bypassing the logging system

Parameters:
  • stream (file object) - the file to which we should write
  • txt (str) - the message
