Shawn O. Pearce 707912b35d Make Tag class only for writing
The Tag class now only supports the creation of an annotated tag
object.  To read an annotated tag, applictions should use RevTag.
This permits us to have exactly one implementation, and RevTag's
is faster and more bug-free.

Shawn O. Pearce cf9537c8ce Correct PersonIdent hashCode() and equals() to ignore milliseconds
Git doesn't store millisecond accuracy in person identity lines,
so a line that we create in Java and round-trip through a Git object
wouldn't compare as being equal.  Truncate to seconds when comparing
values to ensure the same identity is equal.

Shawn O. Pearce 746ebda381 Try really hard to load a commit or tag
When we need the canonical form of a commit or a tag in order to
parse it into our RevCommit or RevTag fields, we really need it as a
single contiguous byte array.  However the ObjectDatabase may choose
to give us a large loader.  In general commits or tags are always
under the several MiB limit, so even if the loader calls it "large"
we should still be able to afford the JVM heap memory required to
get a single byte array.  Coerce even large loaders into a single
byte array anyway.

Shawn O. Pearce 1c2290c8d6 Make ObjectId.compareTo final
Since equals() is now final and does not permit being overridden,
we should do the same thing with compareTo() to prevent different
subclasses from having different ordering behaviors.  This could

Shawn O. Pearce d0043e5d31 Remove unnecessary ObjectId.copy() calls
When RevObject overrode equals() to provide only reference equality
we used to need to convert a RevObject into an ObjectId by copy()
just to use standard Java tools like JUnit assertEquals(), or to
use contains() or get() on standard java.util collection types.

Now that we have removed this override and made ObjectId's equals()
final (preventing any of this mess in the future), some copy()
calls are unnecessary.  Anytime the value is being used as an input
to a lookup routine, or to an equals, we can avoid the copy().

However we still want to use copy() anytime we are given an ObjectId
that may exist long-term, where we don't want the high cost of the
additional storage from a RevCommit extension.  So we can't remove
all uses of copy(), just some of them.

2010-08-04 10:59:35 -07:00
Jeff Schumacher e64cb03065 Fixed bug in scoring mechanism for rename detection
A bug in rename detection would cause file scores to be wrong. The
bug was due to the way rename detection would judge the similarity
between files. If file A has three lines containing 'foo', and file
B has 5 lines containing 'foo', the rename detection phase should
record that A and B have three lines in common (the minimum of the
number of times that line appears in both files). Instead, it would
choose the the number of times the line appeared in the destination
file, in this case file B. I fixed the bug by having the
SimilarityIndex instead choose the minimum number, as it should. I
also added a test case to verify that the bug had been fixed.

Shawn O. Pearce 1a06179ea7 Move PackWriter configuration to PackConfig
This refactoring permits applications to configure global per-process
settings for all packing and easily pass it through to per-request
PackWriters, ensuring that the process configuration overrides the
repository specific settings.

For example this might help in a daemon environment where the server
wants to cap the resources used to serve a dynamic upload pack
request, even though the repository's own pack.* settings might be
configured to be more aggressive.  This allows fast but less bandwidth
efficient serving of clients, while still retaining good compression
through a cron managed `git gc`.

This method may throw exceptions found by checkValidEndOfStream()
but doesn't call super.close() before leaving. It is not clear to me
which resources a close() method should release before it throws an
exception. But those reseources which are not published to the
outside and which therefore cannot be closed by other means have to
be closed in all cases.
I changed the close() method to call super.close() under all
circumstances.

Jeff Schumacher 396fe6da45 Break dissimilar file pairs during diff
File pairs that are very dissimilar during a diff were not being
broken apart into their constituent ADD/DELETE pairs. The leads to
sub-optimal rename detection. Take, for example, this situation:

A file exists at src/a.txt containing "foo". A user renames src/a.txt
to src/b.txt, then adds a new src/a.txt containing "bar".

Even though the old a.txt and the new b.txt are identical, the
rename detection algorithm would not detect it as a rename since
it was already paired in a MODIFY. I added code to split all
MODIFYs below a certain score into their constituent ADD/DELETE
pairs. This allows situations like the one I described above to be
more correctly handled.
