Safe HaskellNone




Constants contains the Haskell constants

The constants in this module are used in Haskell and are also converted to Python.

Do not write any definitions in this file other than constants. Do not even write helper functions. The definitions in this module are automatically stripped to build the target hs. If there are helper functions in this module, they will also be dragged and it will cause compilation to fail. Therefore, all helper functions should go to a separate module and imported.


autoconf constants for Python only ('autotools/build-bash-completion')

htoolsProgs :: [String] Source #

autoconf constants for Python only ('lib/')

hasGnuLn :: Bool Source #

autoconf constants for Python only ('lib/')

Build-time constants

exportDir :: String Source #

gntScripts :: [String] Source #

Various versions

dirVersion :: String Source #

exportVersion :: Int Source #

The version of the backup/export instance description file format we are producing when exporting and accepting when importing. The two are currently tightly intertwined.

configRevision :: Int Source #

The configuration is supposed to remain stable across revisions. Therefore, the revision number is cleared to '0'.

protocolVersion :: Int Source #

Similarly to the configuration (see configRevision), the protocols are supposed to remain stable across revisions.

Cpu pinning separators and constants

cpuPinningAllVal :: Int Source #

Internal representation of "all"

cpuPinningOff :: [Int] Source #

One "all" entry in a CPU list means CPU pinning is off

cpuPinningAllXen :: String Source #

A Xen-specific implementation detail is that there is no way to actually say "use any cpu for pinning" in a Xen configuration file, as opposed to the command line, where you can say xm vcpu-pin domain vcpu all

The workaround used in Xen is "0-63" (see source code function "xm_vcpu_pin" in xen-sourcetoolspythonxenxm/

To support future changes, the following constant is treated as a blackbox string that simply means "use any cpu for pinning under xen".

Image and wipe

opensslCiphers :: String Source #

Ciphers allowed for SSL connections.

For the format, see ciphers(1). A better way to disable ciphers would be to use the exclamation mark (!), but socat versions below 1.5 can't parse exclamation marks in options properly. When modifying the ciphers, ensure not to accidentially add something after it's been removed. Use the "openssl" utility to check the allowed ciphers, e.g. "openssl ciphers -v HIGH:-DES".

Exclusive storage

partMargin :: Double Source #

Error margin used to compare physical disks

partReserved :: Double Source #

Luxid job scheduling

luxidJobqueuePollInterval :: Int Source #

Time intervall in seconds for polling updates on the job queue. This intervall is only relevant if the number of running jobs reaches the maximal allowed number, as otherwise new jobs will be started immediately anyway. Also, as jobs are watched via inotify, scheduling usually works independent of polling. Therefore we chose a sufficiently large interval, in the order of 5 minutes. As with the interval for reloading the configuration, we chose a prime number to avoid accidental 'same wakeup' with other processes.

luxidMaximalRunningJobsDefault :: Int Source #

The default value for the maximal number of jobs to be running at the same time. Once the maximal number is reached, new jobs will just be queued and only started, once some of the other jobs have finished.

luxidMaximalTrackedJobsDefault :: Int Source #

The default value for the maximal number of jobs that luxid tracks via inotify. If the number of running jobs exceeds this limit (which only happens if the user increases the default value of maximal running jobs), new forked jobs are no longer tracked by inotify; progress will still be noticed on the regular polls.

Luxid job death testing

luxidJobDeathDetectionRetries :: Int Source #

The number of attempts to prove that a job is dead after sending it a KILL signal.

luxidJobDeathDelay :: Int Source #

Time to delay (in us) after unsucessfully verifying the death of a job we believe to be dead. This is best choosen to be the average time sending a SIGKILL to take effect.


wconfdDeathdetectionIntervall :: Int Source #

Time itnervall in seconds between checks that all lock owners are still alive, and cleaning up the resources for the dead ones. As jobs dying without releasing resources is the exception, not the rule, we don't want this task to take up too many cycles itself. Hence we choose a sufficiently large intervall, in the order of 5 minutes. To avoid accidental 'same wakeup' with other tasks, we choose the next unused prime number.

wconfLivelockPrefix :: String Source #

The prefix of the WConfD livelock file name.


Confd request type

Confd repl status

Confd node role

A few common errors for confd

Confd request query fields

confdReqqIp :: String Source #

confdMaxClockSkew :: Int Source #

Each request is "salted" by the current timestamp.

This constant decides how many seconds of skew to accept.

TODO: make this a default and allow the value to be more configurable

confdConfigReloadTimeout :: Int Source #

When we haven't reloaded the config for more than this amount of seconds, we force a test to see if inotify is betraying us. Using a prime number to ensure we get less chance of 'same wakeup' with other processes.

confdConfigReloadRatelimit :: Int Source #

If we receive more than one update in this amount of microseconds, we move to polling every RATELIMIT seconds, rather than relying on inotify, to be able to serve more requests.

confdMagicFourcc :: String Source #

Magic number prepended to all confd queries.

This allows us to distinguish different types of confd protocols and handle them. For example by changing this we can move the whole payload to be compressed, or move away from json.

confdMagicFourccBytes :: ByteString Source #

The confd magic encoded in bytes

confdDefaultReqCoverage :: Int Source #

By default a confd request is sent to the minimum between this number and all MCs. 6 was chosen because even in the case of a disastrous 50% response rate, we should have enough answers to be able to compare more than one.

confdClientExpireTimeout :: Int Source #

Timeout in seconds to expire pending query request in the confd client library. We don't actually expect any answer more than 10 seconds after we sent a request.

maxUdpDataSize :: Int Source #

Maximum UDP datagram size.

On IPv4: 64K - 20 (ip header size) - 8 (udp header size) = 65507 On IPv6: 64K - 40 (ip6 header size) - 8 (udp header size) = 65487 (assuming we can't use jumbo frames) We just set this to 60K, which should be enough
