| Method Summary | |
| public static int | alphaKey(int i)
Generate a synthetic base 26 four byte alpha key from an int.
The bytes of the key are between 'A' and 'Z', inclusive. | | public static byte[] | byteArrayCopy(byte[] ba)
| | public static void | checkLatchCount()
| | public static boolean | checkTreeDepth(Database db, int desiredDepth)
Assert if the tree is not this deep. | | public static void | clearIsolationLevel(EnvironmentConfig config)
If a unit test needs to override the isolation level, it should call
this method after calling initEnvConfig. | | public static void | copyFiles(File fromDir, File toDir)
Copies all files in fromDir to toDir. | | public void | debugMsg(String message)
| | public static String | dumpByteArray(byte[] b)
| | public static void | generateRandomAlphaBytes(byte[] bytes)
| | public static BIN | getBIN(Cursor cursor)
Returns the target BIN for the given cursor. | | public static IN | getIN(BIN bin)
Returns the parent IN of the given BIN. | | public static byte[] | getTestArray(int val)
Useful utility for generating byte arrays with a known order. | | public static int | getTestVal(byte[] testArray)
| | public static EnvironmentConfig | initEnvConfig()
Called by each unit test to enforce isolation level settings specified
in the isolationLevel system property. | | public static void | loadLog(Class cls, String resourceName, File envHome)
Loads the given resource relative to the given class, and copies it to
log file zero in the given directory. | | public static void | logBINAndIN(Environment env, Cursor cursor)
Logs the BIN at the cursor provisionally and the parent IN
non-provisionally. | | public static long | logIN(Environment env, IN in, boolean provisional, IN parent)
Logs the given IN. | | public static void | printLatchCount(String msg)
| | public static void | printLatches(String msg)
| | public static void | putUnsignedInt(byte[] buf, long value)
Marshall an unsigned int (long) into a four byte buffer. | | public static void | removeFiles(String msg, File envFile, String suffix)
| | public static void | removeFiles(String msg, File envFile, String suffix, boolean checkRemove)
| | public static void | removeFiles(File envFile, FilenameFilter filter)
Remove files with the pattern indicated by the filename filter from the
environment home directory. | | public static void | removeLogFiles(String msg, File envFile, boolean checkRemove)
Remove je log files from the home directory. | | public static boolean | runLongTests()
| | public static void | setRandomSeed(int seed)
| | public static String | skipVersion(Exception e)
Skip over the JE version number at the start of the exception
message for tests which are looking for a specific message. | | public static long | tallyNodeMemUsage(EnvironmentImpl envImpl)
| | public static long | validateNodeMemUsage(EnvironmentImpl envImpl, boolean assertOnError)
|
| alphaKey | | public static int alphaKey(int i)(Code) | | Generate a synthetic base 26 four byte alpha key from an int.
The bytes of the key are between 'A' and 'Z', inclusive. 0 maps
to 'AAAA', 1 to 'AAAB', etc.
|
| byteArrayCopy | | public static byte[] byteArrayCopy(byte[] ba)(Code) | | a copy of the passed in byte array |
| checkLatchCount | | public static void checkLatchCount()(Code) | | |
| checkTreeDepth | | public static boolean checkTreeDepth(Database db, int desiredDepth) throws DatabaseException(Code) | | Assert if the tree is not this deep. Use to ensure that data setups
are as expected.
|
| clearIsolationLevel | | public static void clearIsolationLevel(EnvironmentConfig config)(Code) | | If a unit test needs to override the isolation level, it should call
this method after calling initEnvConfig.
|
| copyFiles | | public static void copyFiles(File fromDir, File toDir) throws IOException(Code) | | Copies all files in fromDir to toDir. Does not copy subdirectories.
|
| dumpByteArray | | public static String dumpByteArray(byte[] b)(Code) | | length and data of a byte array, printed as decimal numbers |
| generateRandomAlphaBytes | | public static void generateRandomAlphaBytes(byte[] bytes)(Code) | | |
| getTestArray | | public static byte[] getTestArray(int val)(Code) | | Useful utility for generating byte arrays with a known order.
Vary the length just to introduce more variability.
a byte array of length val % 100 with the value of "val" |
| getTestVal | | public static int getTestVal(byte[] testArray)(Code) | | Return the value of a test data array generated with getTestArray
as an int
|
| initEnvConfig | | public static EnvironmentConfig initEnvConfig()(Code) | | Called by each unit test to enforce isolation level settings specified
in the isolationLevel system property. Other system properties or
default settings may be applied in the future.
|
| loadLog | | public static void loadLog(Class cls, String resourceName, File envHome) throws IOException(Code) | | Loads the given resource relative to the given class, and copies it to
log file zero in the given directory.
|
| logBINAndIN | | public static void logBINAndIN(Environment env, Cursor cursor) throws DatabaseException(Code) | | Logs the BIN at the cursor provisionally and the parent IN
non-provisionally. Used to simulate a partial checkpoint or eviction.
|
| printLatchCount | | public static void printLatchCount(String msg)(Code) | | |
| printLatches | | public static void printLatches(String msg)(Code) | | |
| putUnsignedInt | | public static void putUnsignedInt(byte[] buf, long value)(Code) | | Marshall an unsigned int (long) into a four byte buffer.
|
| removeFiles | | public static void removeFiles(String msg, File envFile, String suffix) throws IOException(Code) | | Remove files with this suffix from the je home directory
Parameters:
msg - prefix to append to error messages
Parameters:
envFile - environment directory
Parameters:
suffix - files with this suffix will be removed |
| removeFiles | | public static void removeFiles(String msg, File envFile, String suffix, boolean checkRemove) throws IOException(Code) | | Remove files with this suffix from the je home directory
Parameters:
msg - prefix to append to error messages
Parameters:
envFile - environment directory
Parameters:

| removeFiles | | public static void removeFiles(File envFile, FilenameFilter filter) throws IOException(Code) | | Remove files with the pattern indicated by the filename filter from the
environment home directory.
Note that BadFileFilter looks for this pattern: NNNNNNNN.bad.#

if the unit test is run with -DremoveLogFiles=false
Parameters:
msg - prefix to append to error messages
Parameters:
envFile - environment directory |
| runLongTests | | public static boolean runLongTests()(Code) | | true if long running tests are enabled. |
