ba1719f1ef EnumSet.allOf can take advantage of the bulk BitSet.set(start, end) operation to run faster instead of adding each element individually. 2012-07-06 23:47:42 -06:00

39ad6da290 made getTrueMask in BitSet a lot more rational with fewer code paths. 2012-07-06 23:42:54 -06:00
Mike Keesey
7947981b4b Fixed issue where BitSet didn't handle a range of 64 bits correctly on bulk operations - now just return the predefined MASK which has all the bits set when requesting that all the bits be set. 2012-07-06 23:33:05 -06:00

26209efac2 Fix an off-by-1 error in the remove method. 
The change to only grow the array when the capacity has been reached
exposed a bug in the remove method when shifting the array elements.

990f4fd154 Moved looping through the partitions to change and generating a mask for start and end values into an iterator. This is to use one code path for several bulk-modification operations like flip(start, end) and set(start, end). 2012-07-04 17:12:50 -06:00

153b78f479 fix ArrayList performance issue 
The ArrayList(Collection) constructor was allocating two arrays
instead of one due to an off-by-one error in ArrayList.grow.  This
commit fixes that and makes grow and shrink more robust.

9fe2d69b06 improve seed generation in java.util.Random 
The previous code caused frequent seed collisions for successive calls

patch should avoid such collisions in both single and multi-threaded
cases.

d4da92d300 fix bugs in Deflater and DeflaterOutputStream 
Previously, Deflater.deflate would pass Z_SYNC_FLUSH to zlib
unconditionally, which caused the output to be enormous when setInput
was called repeatedly with very small input buffers.  In order to
allow zlib to buffer output and thereby maximize compression, we must
use Z_NO_FLUSH until Deflater.finish is called, at which point we
switch to Z_FINISH.  We also modify DeflaterOutputStream.close to call
Deflater.finish and write any remaining output to the wrapped stream.

f9197cb076 fix a few HashMap bugs 
1. HashMap.containsValue only checked one hash bucket, which was
 pretty much useless :)

 2. HashMap.MyIterator.remove was broken in that it failed to
 decrement the size field and it did not update the previousCell field
 properly, which sometimes led to more than one cell being removed.

c1c9d2111b remove GNU Classpath and Apache Harmony compatibility code 
Rather than try to support mixing Avian's core classes with those of
an external class library -- which necessitates adding a lot of stub
methods which throw UnsupportedOperationExceptions, among other
comprimises -- we're looking to support such external class libraries
in their unmodified forms.  The latter strategy has already proven
successful with OpenJDK's class library.  Thus, this commit removes
the stub methods, etc., which not only cleans up the code but avoids
misleading application developers as to what classes and methods
Avian's built-in class library supports.

250a77dc13 handle empty strings properly in Pattern.split 
We were incorrectly returning an empty array when the input was empty,
whereas we ought to return an array containing a single empty string.
When the pattern to match was empty, we went into a loop to create an
infinite list of empty strings, only to crash once we've run out of
memory.  This commit addresses both problems.

17c1a552d5 break each Class, Field, and Method into separate classes 
In order to facilitate making the VM compatible with multiple class
libraries, it's useful to separate the VM-specific representation of
these classes from the library implementations.  This commit
introduces VMClass, VMField, and VMMethod for that purpose.

f0f35a920f return a useful value from InflaterInputStream.available 
Note the following excerpt from PNGFileFormat.java in SWT:

     /*
     * InflaterInputStream does not consume all bytes in the stream
     * when it is closed. This may leave unread IDAT chunks. The fix
     * is to read all available bytes before closing it.
     */
     while (stream.available() > 0) stream.read();
     stream.close();

This code relies on the documented behavior of
InflaterInputStream.available, which must return "0 after EOF has been
reached, otherwise always return 1".  This is unlike
InputStream.available, which is documented to return "the number of
bytes that can be read (or skipped over) from this input stream
without blocking by the next caller of a method for this input
stream", and says nothing about how many bytes are left until the end
of stream.

This commit modifies InflaterInputStream.available to behave according
to Sun's documentation.

bf8c856a3c Partially handle cascading logging levels. 
We now maintain a virtual root loger, on which you can set the log
level.  When any logger logs, it finds the effective log level by going
up the parent chain, and finding a meaningful log lvel.  Thus, one can
now do Logger.getLogger("").setLevel(Level.FINER) and set the log level
for all other loggers (that do not specify their own default) to the
level specified.
