fldiff 1.1

fldiff 1.1


fldiff is a graphical diff program. more>>
fldiff is a graphical diff program that shows the differences between two files/directories, or a file/directory and a CVS or Subversion repository. fldiff project is inspired by xdiff (Motif-based) and xxdiff (Qt-based), whose choice of GUI toolkit has hampered their portability to many of the systems I work with.

fldiff uses the Fast Light Toolkit (FLTK) and has been tested on AIX, IRIX, Linux, MacOS X, and Solaris, and should also run on Windows.

Main features:
- Maildir++
- TLS encryption
- SMTP AUTH + SMTP AUTH close
- regexps in badmailfrom and support for badmailto
- external todo
- big remote concurrency patch
- external queue manager
- oversized dns responses
- reverse dns check

LibXDiff 0.23

LibXDiff 0.23


LibXDiff is designed as a library which implements basic and yet complete functionalities to create file differences/patches to both binary and text files. more>>

LibXDiff 0.23 is designed as a library which implements basic and yet complete functionalities to create file differences/patches to both binary and text files. The library uses memory files as file abstraction to achieve both performance and portability. For binary files, LibXDiff implements both (with some modification) the algorithm described in File System Support for Delta Compression by Joshua P. MacDonald, and the algorithm described in Fingerprinting By Random Polynomials by Michael O. Rabin.

While for text files it follows directives described in An O(ND) Difference Algorithm and Its Variations by Eugene W. Myers. Memory files used by the library are basically a collection of buffers that store the file content. There are two different requirements for memory files when passed to diff/patch functions. Text files for diff/patch functions require that a single line do not have to spawn across two different memory file blocks. Binary diff/patch functions require memory files to be compact. A compact memory files is a file whose content is stored inside a single block.

Major Features:

  1. Functionalities inside the library are available to satisfy these rules. Using the XDL_MMF_ATOMIC memory file flag it is possible to make writes to not split the written record across different blocks, while the functions xdl_mmfile_iscompact() , xdl_mmfile_compact() and xdl_mmfile_writeallocate() are usefull to test if the file is compact and to create a compacted version of the file itself.
  2. The text file differential output uses the raw unified output format, by omitting the file header since the result is always relative to a single compare operation (between two files).
  3. The output format of the binary patch file is proprietary (and binary) and it is basically a collection of copy and insert commands, like described inside the MacDonald paper.
  4. The library is compatible with almost every Unix implementation (configure script) and it is also compatible with Windows through custom (nmake) make files. Examples are available inside the test subdirectory of the distribution tarball that show how to use the library. Also, inside the same subdirectory, a regression test in available that tests the library with random data by requiring a diff followed by a patch and comparing results. Regression tests ran successfully for days on my Linux, Solaris, FreeBSD and Windows boxes, and this makes you believe that the library itself is completely ready for production (despite the version number).
Enhancements: Improved performance a in few corner case patterns and in cases where there is a huge input file. Some code cleanup.

Text::Diff 0.35

Text::Diff 0.35


Text::Diff can perform diffs on files and record sets. more>>
Text::Diff can perform diffs on files and record sets.

SYNOPSIS

use Text::Diff;

## Mix and match filenames, strings, file handles, producer subs,
## or arrays of records; returns diff in a string.
## WARNING: can return B diffs for large files.
my $diff = diff "file1.txt", "file2.txt", { STYLE => "Context" };
my $diff = diff $string1, $string2, %options;
my $diff = diff *FH1, *FH2;
my $diff = diff &reader1, &reader2;
my $diff = diff @records1, @records2;

## May also mix input types:
my $diff = diff @records1, "file_B.txt";

diff() provides a basic set of services akin to the GNU diff utility. It is not anywhere near as feature complete as GNU diff, but it is better integrated with Perl and available on all platforms. It is often faster than shelling out to a systems diff executable for small files, and generally slower on larger files.

Relies on Algorithm::Diff for, well, the algorithm. This may not produce the same exact diff as a systems local diff executable, but it will be a valid diff and comprehensible by patch. We havent seen any differences between Algorithm::Diffs logic and GNU diffs, but we have not examined them to make sure they are indeed identical.

Note: If you dont want to import the diff function, do one of the following:

use Text::Diff ();

require Text::Diff;

Thats a pretty rare occurence, so diff() is exported by default.

Java Unified Expression Language 2.1.0

Java Unified Expression Language 2.1.0


Java Unified Expression Language is an implementation of the unified expression language. more>>
Java Unified Expression Language is an implementation of the unified expression language (EL) as specified by the JSP 2.1 standard (JSR-245).
The javax.el.ExpressionFactory implementation is de.odysseus.el.ExpressionFactoryImpl:
// create an expression factory
javax.el.ExpressionFactory factory = new de.odysseus.el.ExpressionFactoryImpl();
Package de.odysseus.el.util provides ready-to-use subclasses of javax.el.ELContext and javax.el.ELResolver:
// create a simple EL context
de.odysseus.el.util.SimpleContext context =
new de.odysseus.el.util.SimpleContext(new de.odysseus.el.util.SimpleResolver());
// define function math:max(int,int)
context.setFunction("math", "max", Math.class.getMethod("max", new Class[]{int.class, int.class}));
// define variable "foo"
context.setVariable("foo", factory.createValueExpression(0, null));
// create expression
javax.el.ValueExpression e = factory.createValueExpression(context, "${math:max(foo,bar)}", null);
// set value for top-level property "bar"
context.setValue(null, "bar", 1);
// evaluate expression...
System.out.println(e.getValue(context)); // --> 1
The JUEL jar may be run from the command line to dump the parse tree of an EL expression:
$ java -jar juel-2.1.x.jar "#{unified(expression[language])}"
+- #{...}
|
+- unified(...)
|
+- [...]

libxmldiff 0.2.5

libxmldiff 0.2.5


libxmldiff aims at providing efficient diff on XML file more>>
libxmldiff library aims at providing efficient diff on XML file
Main features:
- Detection of modified items, added items, removed items
- Not sensitive to item position changes (based on a id).
- Designed to support large XML files (about 100 Mo). For larger files, treat these files with XML Pre Diff Tool would be a good idea.
- Basic XML manipulation (XSLT, Deletion,...)
- Scripting abilities
- Simple to use
How does it work ?
libxmldiff diff two files, and output a file with exactly the same structure (unlike other xml diffing utilities), and containing an extra diff:status attribute.
The meaning of this diff:status argument is :
added : the element has been added.
removed : the element has been removed.
modified : either an argument or the text has been modified, the values will be outputted with the | separator : "before|after".
below : the element itself was not modified, but a child item was.
libxmldiff can use identifiers (attributes or nodes) to see exactly which element has been added or removed, despite the order of the elements.
Enhancements:
- This release fixes a crash while using XSLT parameters in scripts, infinite loops when the script does not exist, and some memory leaks.

Berkeley Unified Parallel C 2.4.0

Berkeley Unified Parallel C 2.4.0


Berkeley Unified Parallel C (UPC) is an extension of the C programming language. more>>
Unified Parallel C, in short UPC, is an extension of the C programming language designed for high performance computing on large-scale parallel machines.

The language provides a uniform programming model for both shared and distributed memory hardware.

The programmer is presented with a single shared, partitioned address space, where variables may be directly read and written by any processor, but each variable is physically associated with a single processor.

UPC uses a Single Program Multiple Data (SPMD) model of computation in which the amount of parallelism is fixed at program startup time, typically with a single thread of execution per processor.

Whats New in This Release:

- Add initial native support for the Cray XT3 via new portals network
- Implement the GASP 1.5 performance instrumentation interface, supporting the
Parallel Performance Wizard (PPW) and other third-party profiling tools.
- Add bupc_ticks_to_ns() - finer granularity timer query
- Add the Berkeley implementations of the UPC collectives and UPC-IO to GCCUPC+UPCR
- Add most of the Berkeley UPC library extensions to GCCUPC+UPCR
- Add upcdecl command-line tool (also online at: http://upc.lbl.gov/upcdecl)
- Add support for alloca() and stdarg.h
- Performance improvements to the BUPC semaphore library for signalling store
- Add bupc_thread_distance() - runtime thread layout query for hierarchical systems
- Add a remote fetch-and-add UPC library extension (initially just for 64-bit ints)
- Allow configure-time tuning of bit distribution in packed pointer-to-shared rep
- Fix the following notable bugs in 2.2.2 (see http://upc-bugs.lbl.gov for details):
- bug525: optimizer crashes on Tru64/CompaqC for libgasnet
- bug1229: More robust preprocessing on Compaq C
- bug1389: ansi-aliasing violations on small local put/get copies
- bug1531: improved lock fairness to remote lock requests
- bug1594: timer inaccuracies on Cray X1E
- bug1645: preprocess-time failure Backslash found where operator expected
- bug1657: PACKAGE_* symbols exposed to UPC code on GCCUPC+UPCR
- bug1683: improve upcrun handling of -shared-heap-max
- bug 1743: More robust behavior when backend C compiler changes
- Improved SRV-based DNS failover for upcc HTTP translation
- Add gzip compression to HTTP netcompile, for faster compiles over slow links
- Improved robustness for SSH netcompile to handle stray output from dotfiles
- Numerous misc minor bug fixes

DiffJ 1.1.2

DiffJ 1.1.2


DiffJ is a commandline application that compares Java files based on content. more>>
DiffJ is a commandline application that compares Java files based on content, not whitespace, comments, or reordering of types, methods, or fields.
Its output is based on the Unix program diff, and it also has a "brief" output format for a concise summary of what changed. It can work on directories recursively, looking for matching filenames, like "diff -r dir0 dir1".
DiffJ is primarily for developers refactoring and reformatting Java code, for which most difference tools tend to produce misleading results regarding the type and extent of changes.
Enhancements:
- The difference comparator of functions (methods and constructors) has been fixed, and the default Java source is now 1.5.
