Package interval provides two implementations for an interval tree.

Package pretty prints documents based on a target line width.

CombineUniqueInt64 combines two ordered int64 slices and returns the result without duplicates.

CombineUniqueString combines two ordered string slices and returns the result without duplicates.

ConstantWithMetamorphicTestBool is like ConstantWithMetamorphicTestValue except it returns the non-default value half of the time (if running a metamorphic build).

ConstantWithMetamorphicTestChoice is like ConstantWithMetamorphicTestValue except it returns a random choice (equally weighted) of the given values.

ConstantWithMetamorphicTestRange is like ConstantWithMetamorphicTestValue except instead of returning a single metamorphic test value, it returns a random test value in the semi-open range [min, max).

ConstantWithMetamorphicTestValue should be used to initialize "magic constants" that should be varied during test scenarios to check for bugs at boundary conditions.

CRC32 computes the Castagnoli CRC32 of the given data.

EnableRacePreemptionPoints enables goroutine preemption points declared with RacePreempt for builds using the race build tag.

EqualPtrFields uses reflection to check two "mirror" structures for matching pointer fields that point to the same object.

Every is a convenience constructor for an EveryN object that allows a log message every n duration.

GetSingleRune decodes the string s as a single rune if possible.

GetSmallTrace returns a comma-separated string containing the top 5 callers from a given skip level.

IsMetamorphicBuild returns whether this build is metamorphic.

MakeFastIntSet returns a set initialized with the given values.

MakeFNV64 initializes a new FNV64 hash state.

MakeStringListBuilder creates a StringListBuilder, which is used to print out lists of items.

MakeUnresolvedAddr populates an UnresolvedAddr from a network and raw address string.

MakeUnresolvedAddrWithDefaults creates a new UnresolvedAddr from a network and raw address string, using the following defaults if not given: - Network: tcp - Host: local hostname or 127.0.0.1 - Port: given default port.

MoveTopKToFront moves the top K elements to the front.

NewUnresolvedAddr creates a new UnresolvedAddr from a network and raw address string.

Pluralize returns a single character 's' unless n == 1.

RacePreempt adds a goroutine preemption point if CockroachDB was built with the race build tag and preemption points have been enabled.

RemoveTrailingSpaces splits the input string into lines, trims any trailing spaces from each line, then puts the lines back together.

ToLowerSingleByte returns the lowercase of a given single ASCII byte.

TruncateString truncates a string to a given number of runes.

DisableMetamorphicEnvVar can be used to disable metamorphic tests for sub-processes.

RaceEnabled is true if CockroachDB was built with the race build tag.

IsolatedTestAddr is an address to use for tests that need extra isolation by using more addresses than 127.0.0.1 (support for this is platform-specific and only enabled on Linux).

TestAddr is an address to use for test servers.

EveryN provides a way to rate limit spammy events.

FastIntMap is a replacement for map[int]int which is more efficient when both keys and values are small.

FastIntSet keeps track of a set of integers.

FNV64 encapsulates the hash state.

NoCopy may be embedded into structs which must not be copied after the first use.

StringListBuilder helps printing out lists of items.

UnresolvedAddr is an unresolved version of net.Addr.
