FileUtils#readFileToByteArray: optimize reading of files with known size Add convenience methods for copyToDirectory Javadoc contradictory for FileFilterUtils.ageFileFilter(cutoff) and the filter it constructs: AgeFileFilter(cutoff) FileUtilTestCase.testForceDeleteDir() should not delete testDirectory parent fix Tailer.run race condition runaway logging getPrefixLength return -1 if unix file contains colon FileUtilsTestCase#testContentEqualsIgnoreEOL fails on Windows .gitattributes not correctly applied Allow Specifying Initial Buffer Size of DeferredFileOutputStream. ThresholdingOutputStream.thresholdReached() results in FileNotFoundException. After a few unit tests, a few newly created directories not cleaned completely. Exceptions are suppressed incorrectly when copying files. Update platform requirement to Java 7. BOMInputStream shouldn't sort array of BOMs in-place. Deprecate methods FileSystemUtils.freeSpaceKb(). Make LineIterator implement Closeable to support try-with-resources statements. Deprecated of all IOUtils.closeQuietly() methods and use try-with-resources internally. Add infinite circular input stream Add a ByteOrderFactory class. Add ObservableInputStream Add MessageDigestCalculatingInputStream Add convenience methods for reading class path resources. Remove org.apache.commons.io.Java7Support Typo: In an IOUtils.java comment it says "focussed" instead of "focused". Converted all test cases to JUnit 4 Add ValidatingObjectInputStream for controlled deserialization adds an endOfFileReached method to the TailerListener FilenameUtils should handle embedded null bytes Changed/Corrected algorithm for waitFor Support for additional encodings in ReversedLinesFileReader BOMInputStream.skip returns wrong count if stream contains no BOM Setter method for threshold on ThresholdingOutputStream FileUtils.waitFor(...) swallows thread interrupted status Support for symlinks with missing target. Added support for JDK7 symlink features when present Added testcase to show this was fixed with IO-423 Correct exception message in FileUtils.getFile(File, String...) Introduce new class AppendableOutputStream Update to JUnit 4.12 IOExceptionWithCause no longer needed Add WindowsLineEndingInputStream and UnixLineEndingInputStream. Add a BoundedReader, a wrapper that can be used to constrain access to an underlying stream when used with mark/reset - to avoid overflowing the mark limit of the underlying buffer. Regression in FileUtils.readFileToString from 2.0.1 ant test fails - resources missing from test classpath Document that FileUtils.deleteDirectory, directoryContains and cleanDirectory may throw an IllegalArgumentException in case the passed directory does not exist or is not a directory. Add API IOUtils.closeQuietly(Closeable...) Javadoc fixes, mostly to appease 1.8.0 Deprecate Charsets Charset constants in favor of Java 7's java.nio.charset.StandardCharsets Readfully() That Returns A Byte Array Overload IOUtils buffer methods to accept buffer size FileUtils.sizeOfDirectory can throw IllegalArgumentException FileUtils.sizeOfDirectoryAsBigInteger can overflow. Ensure that recursive calls all use BigInteger Chunked IO for large arrays. Added writeChunked(byte[], OutputStream) and writeChunked(char[] Writer) Added ChunkedOutputStream, ChunkedWriter FileUtils.doCopyFile can potentially loop for ever Exit loop if no data to copy FileUtils.doCopyFile caches the file size; needs to be documented Added Javadoc; show file lengths in exception message Convert IOCase to a Java 1.5+ Enumeration [N.B. this is binary compatible] Add Methods for Buffering Streams/Writers To IOUtils Added overloaded buffer() methods - see also IO-330 IOUtils#toBufferedOutputStream/toBufferedWriter to conditionally wrap the output Added overloaded buffer() methods - see also IO-233 Add FileUtils.copyInputStreamToFile API with option to leave the source open. See copyInputStreamToFile(final InputStream source, final File destination, boolean closeSource) FileUtils.copyInputStreamToFile should document it closes the input source Tailer erroneously considers file as new. Fix to use file.lastModified() rather than System.currentTimeMillis() CharSequenceInputStream#reset() behaves incorrectly in case when buffer size is not dividable by data size. Fix code so skip relates to the encoded bytes; reset now re-encodes the data up to the point of the mark CharSequenceInputStream - add tests for available() Fix code so it really does reflect a minimum available. getPrefixLength returns null if filename has leading slashes Javadoc: add examples to show correct behaviour; add unit tests FileUtils.listFilesAndDirs includes original dir in results even when it doesn't match filter Javadoc: clarify that original dir is included in the results Add ByteArrayOutputStream.toInputStream() ClassLoaderObjectInputStream does not handle primitive typed members A constant for holding the BOM character (U+FEFF) Deprecate all methods that use the default encoding When a file is rotated, finish reading previous file prior to starting new one Commons IO Tailer does not respect UTF-8 Charset. What should happen in FileUtils.sizeOf[Directory] when an overflow takes place? Added Javadoc. FileUtils.moveDirectory can produce misleading error message on failiure FilenameUtils.splitOnTokens(String text) check for '**' could be simplified WildcardFileFilter ctors should not use null to mean IOCase.SENSITIVE when delegating to other ctors IOUtils.contentEquals* methods returns false if input1 == input2, should return true. Add API FileUtils.forceMkdirsParent(). Add API Charsets.requiredCharsets(). Add IOUtils.skip and skipFully(ReadableByteChannel, long). Add IOUtils.read and readFully(ReadableByteChannel, ByteBuffer buffer). [Tailer] InterruptedException while the thread is sleeping is silently ignored Add API IOUtils.copy(InputStream, OutputStream, int) Add API with array offset and length argument to FileUtils.writeByteArrayToFile. Spelling fixes. Missing information in IllegalArgumentException thrown by org.apache.commons.io.FileUtils#validateListFilesParameters. Supply a hook method allowing Tailer actively determining stop condition. Improper JavaDoc comment for FilenameUtils.indexOfExtension. Make IOUtils.EOF public and reuse it in various classes. org.apache.commons.io.comparator Javadoc is inconsistent with real code. Yottabyte (YB) incorrectly defined in FileUtils. Tailer locks file from deletion/rename on Windows. Tailer erroneously considers file as new. Tailer#readLines - incorrect CR handling. FileUtils.toURLs throws NPE for null parameter; document the behavior. Export OSGi packages at version 1.x in addition to 2.x. Add XmlStreamReader support for UTF-32. BOMInputStream wrongly detects UTF-32LE_BOM files as UTF-16LE_BOM files in method getBOM(). Improve tailer's reading performance. Improve Tailer performance with buffered reads (see IO-332). FileUtils.writeLines uses unbuffered IO. Add byteCountToDisplaySize(BigInteger). Add new FileUtils.sizeOf[Directory] APIs to return BigInteger. Add IOUtils.toByteArray methods to work with URL and URI. Add missing Charset sister APIs to method that take a String charset name. FileUtils.sizeOfDirectory follows symbolic links. Add and use class Charsets. ByteOrderMark UTF_32LE is incorrect. Add Charset sister APIs to method that take a String charset name. Add IOUTils.toBufferedReader(Reader) Allow applications to provide buffer (or size) for copyLarge methods. IOUtils.read(InputStream/Reader) ignores the offset parameter CharSequenceInputStream(CharSequence s, Charset charset, int bufferSize) ignores bufferSize New copyLarge() method in IOUtils that takes additional offset, length arguments FileUtils.moveDirectoryToDirectory removes source directory if destination is a sub-directory ReaderInputStream#read(byte[] b, int off, int len) should check for valid parameters Use terabyte (TB), petabyte (PB) and exabyte (EB) in FileUtils.byteCountToDisplaySize(long size) ReaderInputStream#read(byte[] b, int off, int len) should always return 0 for length == 0 FileUtils.listFiles() doesn't return directories "FileUtils#deleteDirectoryOnExit(File)" does not work BoundedInputStream.read() treats max differently from BoundedInputStream.read(byte[]...) CharSequenceInputStream to efficiently stream content of a CharSequence ReaderInputStream optimization: more efficient reading of small chunks of data Various methods of class 'org.apache.commons.io.FileUtils' incorrectly suppress 'java.io.IOException' The second constructor of Tailer class does not pass 'delay' to the third one TeeOutputStream does not call branch.close() when main.close() throws an exception ArrayIndexOutOfBoundsException in BOMInputStream when reading a file without BOM multiple times Add IOUtils.closeQuietly(Selector) necessary IOUtils.closeQuietly() should take a ServerSocket as a parameter Add read/readFully methods to IOUtils Supply a ReversedLinesFileReader Add new function FileUtils.directoryContains. FileUtils.contentEquals and IOUtils.contentEquals - Add option to ignore "line endings" Added contentEqualsIgnoreEOL methods to both classes Use standard Maven directory layout Add IOUtils API toString for URL and URI to get contents Add API FileUtils.copyFile(File input, OutputStream output) Dubious use of mkdirs() return code ReaderInputStream enters infinite loop when it encounters an unmappable character FileUtils.moveFile() JavaDoc should specify FileExistsException thrown FileAlterationObserver has no getter for FileFilter Add FileUtils.getFile API with varargs parameter ClassLoaderObjectInputStream does not handle Proxy classes FileAlterationMonitor.stop(boolean allowIntervalToFinish) Add new APPEND parameter for writing string into files Tailer returning partial lines when reaching EOF before EOL FileUtils.copyFile() throws IOException when copying large files to a shared directory (on Windows) FileSystemUtils.freeSpaceKb throws exception for Windows volumes with no visible files. Improve coverage by also looking for hidden files. Add new read method "toByteArray" to handle InputStream with known size. TODO: Convert RELEASE-NOTES.txt from 2.0.1? TODO: Convert RELEASE-NOTES.txt from 2.0? TODO: Convert RELEASE-NOTES.txt from 1.4? Some tests, which are implicitly assuming a Unix-like file system, are now skipped on Windows. Created the FileCleaningTracker, basically a non-static version of the FileCleaner, which can be controlled by the user. EndianUtils - both readSwappedUnsignedInteger(...) methods could return negative numbers due to int/long casting.
