const MetaDataVersion = "1.0"

MetaDataVersion is the version of the metadata file. This should update the major version with breaking changes, and t3c versions should strive to maintain compatibility at least one major version back, so features like tracking t3c-owned files continue to work through upgrades.

Functions

func CombineOwnedFilePaths 

func CombineOwnedFilePaths(am *ApplyMetaData, bm *ApplyMetaData) []string

CombineOwnedFilePaths combines the owned file paths of two metadata objects.

This is primarily useful when a config run, such as revalidate, adds owned files, but not all owned files, but we don't want to write metadata incidating we don't own existing files, so this can be used to combine the new files with the previous metadata.

Both am and bm are may be nil, in which case the files from the non-nil object is returned, or an empty array if both are nil.

func CommentsFilter 

func CommentsFilter(body []string, lineComment string) []string

CommentsFilter is used to remove comment lines from config files while making comparisons.

func Do 

func Do(cmdStr string, args ...string) ([]byte, []byte, int)

This is a convenience wrapper around os/exec. Since t3c only needs to make simple calls and get the stdout, stderr, and code, this provides a simpler and terser interface.

If you need anything more complex, or don't find this simpler, you should probably use os/exec directly.

Each arg must be passed as its own string. Unfortunately, Go doesn't have a way to pass multiple args as a single string, and splitting on spaces would require complex quote parsing.

Note each arg must be passed without quotes. Go calls the app with args as if they were quoted. if you add quotes, they'll be passed to the command literally, as if you called 'mycommand "\"escaped-quotes\""`.

Note if Go fails to run the command, the error from Go will be returned as the stderr and the code -1, which will differ from what would have been returned by a command line.

func DoInput 

func DoInput(input []byte, cmdStr string, args ...string) ([]byte, []byte, int)

DoInput is like Do but takes the stdin to pass to the command.

func FilterDSS 

func FilterDSS(dsses []tc.DeliveryServiceServer, dsIDs map[int]struct{}, serverIDs map[int]struct{}) []tc.DeliveryServiceServer

func FilterParams 

func FilterParams(params []tc.Parameter, configFile string, name string, value string, omitName string) []tc.Parameter

FilterParams filters params and returns only the parameters which match configFile, name, and value. If configFile, name, or value is the empty string, it is not filtered. Returns a slice of parameters.

func GetDataFuncs 

func GetDataFuncs() map[string]func(TCCfg, io.Writer) error

func GetServerUpdateStatus 

func GetServerUpdateStatus(cfg TCCfg) (*atscfg.ServerUpdateStatus, error)

func InstallDir 

func InstallDir() string

initializes InstallDir to executable dir If error, returns "/usr/bin" as default.

func MakeReqHdr 

func MakeReqHdr(md ReqMetaData) http.Header

func NewLineFilter 

func NewLineFilter(str string) string

NewLineFilter removes carriage returns from config files while making comparisons.

func OwnershipCk 

func OwnershipCk(path string, uid int, gid int) bool

OwnershipCk will compare owner and group settings against existing file and owner/group settings provided.

func ParamsToMap 

func ParamsToMap(params []tc.Parameter) map[string]string

ParamsToMap converts a []tc.Parameter to a map[paramName]paramValue. If multiple params have the same value, the first one in params will be used an an error will be logged. See ParamArrToMultiMap.

func ParamsToMultiMap 

func ParamsToMultiMap(params []tc.Parameter) map[string][]string

ParamArrToMultiMap converts a []tc.Parameter to a map[paramName][]paramValue.

func PermCk 

func PermCk(path string, perm int) bool

PermCk will compare file permissions against existing file and octal permission provided.

func ReadFile 

func ReadFile(f string) []byte

ReadFile reads a file and returns the file contents.

func SetUpdateStatus 

func SetUpdateStatus(cfg TCCfg, serverName tc.CacheName, configApply, revalApply *time.Time) error

SetUpdateStatus sets the queue and reval status of serverName in Traffic Ops.

func SetUpdateStatusCompat 

func SetUpdateStatusCompat(cfg TCCfg, serverName tc.CacheName, configApply, revalApply *time.Time, configApplyBool, revalApplyBool *bool) error

SetUpdateStatusCompat sets the queue and reval status of serverName in Traffic Ops. *** Compatability requirement until ATC (v7.0+) is deployed with the timestamp features

func UnencodeFilter 

func UnencodeFilter(body []string) []string

UnencodeFilter translates HTML escape sequences while making config file comparisons.

func UserAgentStr 

func UserAgentStr(appName string, versionNum string, gitRevision string) string

func ValidateURL 

func ValidateURL(u *url.URL) error

func VersionStr 

func VersionStr(appName string, versionNum string, gitRevision string) string

VersionStr returns a common version string format for all t3c apps. The appName is the command itself, e.g. t3c-apply. The versionNum is the version number from the build system. It should include the major, minor, git revision, and a monotonically increasing number, e.g. '4.2.1234.abc123'.

func WriteActionLog 

func WriteActionLog(action ActionLogAction, status ActionLogStatus, metaData *ApplyMetaData)

WriteActionLog writes the given action and status to both the info log and the given metadata object.

The metaData may be nil, and should be if this is being called after the final git commit, to prevent modifying the file after the commit.

func WriteChkconfig 

func WriteChkconfig(cfg TCCfg, output io.Writer) error

WriteChkconfig writes the chkconfig for cfg.CacheHostName to output. Note this is identical to /ort/serverName/chkconfig.

func WriteConfig 

func WriteConfig(cfg TCCfg, output io.Writer) error

WriteConfig writes the Traffic Ops data necessary to generate config to output.

func WriteData 

func WriteData(cfg TCCfg) error

func WritePackages 

func WritePackages(cfg TCCfg, output io.Writer) error

WriteORTServerPackages writes the packages for serverName to output. Note this is identical to /ort/serverName/packages.

func WriteServerUpdateStatus 

func WriteServerUpdateStatus(cfg TCCfg, output io.Writer) error

WriteServerUpdateStatus writes the Traffic Ops server update status to output. Note this is identical to the Traffic Ops API's /servers/{{host name}}/update_status endpoint except it omits the '[]' wrapper.

func WriteStatuses 

func WriteStatuses(cfg TCCfg, output io.Writer) error

WriteStatuses writes the Traffic Ops statuses to output. Note this is identical to /statuses except it omits the '{response:' wrapper.

func WriteSystemInfo 

func WriteSystemInfo(cfg TCCfg, output io.Writer) error

WriteSystemInfo writes the "system info" to output.

This is the same info as the Traffic Ops API's /system/info endpoint, which is actually just all Parameters with the config_file 'global'. Note this is different than the more common "global parameters", which usually refers to all Parameters on the Profile named 'GLOBAL'.

This is identical to the /system/info endpoint, except it does not include a 

'{response: {parameters:' wrapper.

type ActionLogAction 

type ActionLogAction string

ActionLogAction is an action t3c performs which affects the state of the machine. Things that don't affect the state of the machine are not considered actions.

For example, requesting Traffic Ops is not an 'action', but restarting ATS or modifying a config file is.

Actions also include the t3c-apply run starting and finishing, to help delineate the actions of different runs in the log.

type ActionLogStatus 

type ActionLogStatus string

type ApplyFilesFlag 

type ApplyFilesFlag string
const (
	ApplyFilesFlagInvalid ApplyFilesFlag = ""
	ApplyFilesFlagAll     ApplyFilesFlag = "all"

	// metadata files from different servers.
	ServerHostName string `json:"server-hostname"`

	// Time is an RFC3339Nano timestamp of the time t3c-apply ran for this metadata.
	// This should be treated as approximate, as it could be the start time, end time, or
	// any inexact time in-between.
	// However, times of different metadata files should always be monotonically increasing.
	Time string `json:"time"`

	// ReloadedATS is whether this run restarted ATS.
	// Note this is whether ATS was actually restarted, not whether it would have been,
	// e.g. because of --report-only or --service-action.
	ReloadedATS bool `json:"reloaded-ats"`

	// RestartedATS is whether this run restarted ATS.
	// Note this is whether ATS was actually restarted, not whether it would have been,
	// e.g. because of --report-only or --service-action.
	RestartedATS bool `json:"restarted-ats"`

	// UnsetUpdateFlag is whether this t3c-apply run unset the update flag for this server.
	// Note this is whether the flag was actually unset, not whether it would have been e.g.

	UnsetUpdateFlag bool `json:"unset-update-flag"`

	// UnsetRevalFlag is whether this t3c-apply run unset the revalidate flag for this server.
	// Note this is whether the flag was actually unset, not whether it would have been e.g.
	// because of --no-unset-reval-flag or --report-only.
	UnsetRevalFlag bool `json:"unset-reval-flag"`

	// InstalledPackages is which yum packages were installed.
	// Note this packages actually installed, not what would have been e.g.

	InstalledPackages []string `json:"installed-packages"`

	// OwnedFilePaths is the list of files t3c-apply produced in this run.
	//
	// This can be used to know which files in the ATS config directory were produced by t3c,
	// and which were produced by some other means.
	//
	// Note this is all files produced, not necessarily all files written to disk. This
	// will include files generated, but not changed on disk because they had no
	// semantic diff from the existing file.
	//
	// This may be used in the future for t3c-apply to delete files produced by a previous
	// run which no longer exist (for example, Header Rewrites from a Delivery Service
	// no longer assigned to this server).
	//
	// Files are the full path and file name.
	OwnedFilePaths []string `json:"owned-files"`

	// Succeeded is whether this t3c-apply run generally succeeded.
	//
	// Note not all scenarios are black or white success-or-fail.
	// For example, files may be successfully created, but reloading ATS may fail.
	// In these scenarios, t3c-apply will attempt to set Succeeded to false,
	// but also attempt to set other metadata about what was actually performed.
	//
	// But when partial failure occurrs, nothing is guaranteed in the metadata.
	// Operators should consider the logs authoritative over the metadata.
	Succeeded bool `json:"succeeded"`

	// PartialSuccess indicates that some actions were successful, but
	// later actions failed.
	//
	// This is a bad place to be, because it means some things were changed,
	// but not everything that needed to be. This is often not fatal, because,
	// for example, if config files were changed by ATS failed to reload,
	// those config files typically needed placed anyway.
	//
	// But nevertheless, partial success is potentially catastrophic, and operators
	// are strongly encouraged to set alarms and read logs in the event it occurs,
	// to determine what was changed, what failed, and what actions need taken.
	PartialSuccess bool `json:"partial-success"`

	Actions []ApplyMetaDataAction `json:"actions"`
}

ApplyMetaData is metadata about a t3c-apply run. Always use NewApplyMetaData, don't use a literal to construct a new object.

func GetConfigData 

func GetConfigData(toClient *toreq.TOClient, disableProxy bool, cacheHostName string, revalOnly bool, oldCfg *ConfigData, version string) (*ConfigData, error)

GetTOData gets all the data from Traffic Ops needed to generate config. Returns the data, the addresses of all Traffic Ops' requested, and any error.

The toClient is the Traffic Ops client, which should already be initialized and connected.

The disableProxy arg is whether to disable using any Traffic Ops proxy configured via the global TrafficOpsProxyParameterName. If the Parameter exists, this will connect to Traffic Ops to get the global parameters, get the Parameter, and then change the toClient to use it.

The cacheHostName is the hostname of the cache to get config generation data for.

The oldCfg is previous config data which was cached. May be nil, if the caller has no previous data. If it exists and is usable, If-Modified-Since requests will be made and the cache re-used where possible.

The version is a unique version of the application, which should change with any compatibility changes. Old config with a different version than the current won't be used (though in the future, smarter compatibility could be added).

The revalOnly arg is whether to only get data necessary to revalidate, versus all data necessary to generate cache config.

type ServiceNeeds 

type ServiceNeeds string

ServiceNeeds represents whether we need to reload or restart Traffic Server, as returned by t3c-check-reload.

Note the default is success, not invalid. With enums, typically invalid should be the default, but in this case, this represents the return of an app which returns nothing on successes (which is typical of POSIX apps), so we want the default empty string to represent that. Hence, the default value of ServiceNeeds is success, not invalid 

const (
	ServiceNeedsNothing ServiceNeeds = "" // default is nothing, and print nothing if nothing needs done
	ServiceNeedsRestart ServiceNeeds = "restart"
