What is the expected output? What do you see instead?
Expected output in diff report
Showing the change in blue color which is not required.
There won't be any difference in the HTML output when we add border="0" or

I am using daisydiff to view HTML file differences on a local filesystem. The
output is generated in the source directory, so that existing links to images
etc are still viewable.
The generated html however contains links like this:
<link href="css/diff.css" type="text/css" rel="stylesheet">
<script src="js/tooltip/wz_tooltip.js" type="text/javascript"></script>
In my situation, the css and js directories are not under the current directory.
So it would be useful to specify the location as a commandline parameter, eg a
single parameter that is used as a prefix to both the examples above.

Attached you will find a patch for current SVN (12 November 2009) that does
the following.
1. Conversion of some classes to interfaces (e.g HTMLDiffer and
HTMLOutput) so that developers can plugin alternative output formats
(e.g. PDF)
2. Some unit tests (and addition of Junit 4 instead of Junit 3). Coverage
is now almost 45%
3. An extra field in the internal structures of daisyDiff so that in
the case of layout removals (e.g. removal
of an italics tag around a sentence) the output can also "remember"
what was the old layout. Currently only a textual representation is
kept (the one shown on the tooltips) but this is not enough for
further processing.
All changes are essentially refactorings so that diff functionality
has not changed at all.
Please review and apply if you are happy with it.
I would be glad to change it further if there are any problems (coding
style, comments, naming e.t.c.)
The patch was created with Eclipse. I tested it by checking out from SVN
the daisy-diff source and applied it again via Eclipse.
Thank you

I want to compare only two html Strings rather than entire file and get the
output as an html String.
This is required because we need to compare different html strings in a Loop.
HTMLs are retrieved from the database.
My need is:
String 1 = html1
String 2 = html2
After comparing String 1 and 2, I should get third String with the differences
highlighted

I have a question - what was the idea with the splitting?
Was it meant as followed?
>>>
Because the parent of the deleted text node doesn't exist anymore (though
it might not be true), but the surrounding text nodes did have common
ancestor, we should add the "missing" child that contained the deleted
node previously
<<<
I will try to fix this, but I would like to know the answer to the
question above, so I won't break anything accidentally.
The place where the bug is happening:
org.outerj.daisy.diff.html.TextNodeComparator.markAsDeleted(...)
the code goes like the following:
...
if (prevResult.getLastCommonParentDepth() >
nextResult.getLastCommonParentDepth()) {
// Inserting at the front
if (prevResult.isSplittingNeeded()) {
prevLeaf.getParent().splitUntill(
prevResult.getLastCommonParent(),
prevLeaf,
true);
}
prevLeaf = deletedNodes.remove(0).copyTree();
//this is the bug, as not all common parents allowed
//to have text content. This causes the deleted text to
//be displayed outside of the structure.
//The splitting is never used here.
prevLeaf.setParent(prevResult.getLastCommonParent());
prevResult.getLastCommonParent().addChild(
prevResult.getIndexInLastCommonParent() + 1,
prevLeaf);
} else if (prevResult.getLastCommonParentDepth() <
nextResult.getLastCommonParentDepth()) {

So I rewrote the Javascript part using jQuery and jQuery UI while making the
code cleaner and probably more robust. The code should require no modification
in other parts of Daisydiff and right now has feature parity with the original
version. The only difference is that a change summary dialog is displayed when
moving the mouse over a changed part, but that can be reverted by deleting a
single keyword in the code.
If anyone is interested, I put my code on GitHub:

1. view the two attached files - note that div tags without content are
not explicitly closed but are closed with />
2. note that only difference between files is that new.html has some text
added in a div, which is now closed with </div> - see div for
class="bwStorySubheadline"
3. run Diff report
What is the expected output? What do you see instead?
Expected output is to only see added text as a difference between the two
files.
Instead, I see changed style on everything following the end div for the
added text.
Changes indicate that text was "moved out of a division with class (name
of class with added text) ..."
But nothing was moved out of a division; it seems that /> is not being
recognized as an end tag.

Regarding Kostis's test data that Carsten added a test to run, committed at
http://code.google.com/p/daisydiff/source/detail?r=157
It would be better to run this as multiple tests instead of 1. I'm new to
JUnit 4 but standard practice seems to be that you use Parameterized for this.
And that the standard problem with that is that the test names are all test[0],
test[1] etc. That's not great, but it's an improvement.
http://stackoverflow.com/questions/358802/junit-test-with-dynamic-number-of

http://stackoverflow.com/questions/650894/change-test-name-of-parameterize

DaisyDiff's html diff can be extremely resource hungry. Eg our wiki recently
encountered a page diff (admittedly a very large one) that caused the system to
run out of memory. Unit testing the difference at fault I gave it 900MB and it
still OOMEd.
There are numerous ways that the resource use could be limited. Eg modifying
the LCSSettings' limits, or implementing skipRangeComparison. But I'd like to
just make it cancellable externally (because it's easier).
The Eclipse RangeDifferencer at the heart of the HTMLDiffer can be passed an
IProgressMonitor, whose isCancelled method is often checked. When the
IProgressMonitor is cancelled, that diffing operation terminates.
I'm working on a simple change to DaisyDiff to include a diff(IProgressMonitor
progressMonitor, TextNodeComparator leftComparator, TextNodeComparator
rightComparator) method that passes that progressMonitor through to the various
calls to RangeDifference.
That's the most straightforward way to implement the functionality I need, but
it's not necessarily the best. Eg people might think we shouldn't leak the
reliance on Eclipse classes to client code, which would be pretty reasonable.
Also I haven't done anything about the rest of the IProgressMonitor interface
at the moment, so it's a bit misleading to take one.

What steps will reproduce the problem?
1.Create 2 identic html files
2.Delete some text from the middle of an HTML element, so some text remains
in the element before and after the deleted text
3.Change some attributes of the HTML element with the deleted text.
What is the expected output? What do you see instead?
Expected: display of all the text with the deleted text highlighted in red
and crossed out
Instead: some of the remaining text is duplicated.
Please use labels and text to provide additional information.
The problem again lies in the comparison of tags by semantic rather than
object comparison.
During the splitting 2 new tags are added to the children collection of
the parent. Those 2 new tags represent "splitted node" and for that reason
they have exactly the same name and attributes as the original:
>>>
TagNode part1 = new TagNode(null, getQName(), getAttributes());
TagNode part2 = new TagNode(null, getQName(), getAttributes());
<<<
Now we have 3 "equal" HTML tags and the original tag has to be removed. Of
course first found is the one that is going to be removed. But the tags
reside in this order: <part before split> <part after split> <original>.
So instead of the original the <part before split> is removed and now the
original contains part of the nodes from <part after split>. Those nodes
are duplicated as the result.
Notice, that the reason for this bug is the same as for the original
statement in Issue 8.

Hi,
I'm interested in using daisydiff for a non-java project, the easiest way
would be to shell out and feed daisydiff.jar two local files, and read the
results file. Unfortunately, it seems to accept only remote addresses...
What steps will reproduce the problem?
1.
$ cat > t1
<h1>test</h1>
^C
2. cat > t2
<h1>test two</h1>
^C
3. java -jar daisydiff.jar t1 t2

What steps will reproduce the problem?
1. I use the java implementation of daisydiff (see DiffALaDaisy.java) which
works fine.
2. If you compare the file1.xml to another file with the same content, in the
result namespaces are gone (redsys:fn got fn ...)
What is the expected output? What do you see instead?
An html output whick includes namespaces.
Namespaces (redsys) are removed. I dont know if its an issue of the htmlcleaner
or daisydiff.
What version of the product are you using? On what operating system?
DaisyDiff 1.1, on Windows7, jdk 1.5
Please provide any additional information below.
The question is: how to tell daisydiff to accept namespaces and do not remove
it.
Thanks for any hint.

What steps will reproduce the problem?
1. Use 2 exactly same HTML files, where one of the elements has "style"
attribute with values containing multiple rules
(e.g. style="text-decoration: underline; font-variant: italic").
2. Reverse the order of the css rules in the second file
(e.g. style="font-variant: italic; text-decoration: underline")
Same result can be achieved with "class" attribute. E.g.:
<h1 class="pagetitle holidaystyle"> and
<h1 class="holidaystyle pagetitle">
In fact, you don't even have to swap places - just add an extra space in
the middle.
What is the expected output?
no difference
What do you see instead?
"Moved out of ... moved in..."
What version of the product are you using?
1.0
On what operating system?
Windows XP
Please provide any additional information below.
Attached are:
2 files with a sample of the bug
corrected file org.outerj.daisy.diff.html.dom.helperAttributesMap.java
I also added some comments (hope it's ok).
Of course, to be absolutely correct the style rule should resolve the
styles and compare the rules too (to see that 2 style don't use the same
name for different set of rules). However, I think that in most cases this
won't happen.
This situation (with the mixed styles order and mixed class names order)
often occurs when the HTML is generated by some program as a result of
writing out some Document model after the changes were done in some
WYSIWYG HTML editor (like using javax.swing.text.html package).

(From the mailing list)
Hi,
when comparing text, daisydiff currently disregards the text's structure.
Whether some text is inside a single paragraph or in different tables, a
headline and a block -- daisydiff doesn't care.
This leads to changes being flagged out of their original context, i.e. a
change done to a table cell will displayed in the headline above the table.
The reasons for that is, that DomTreeBuilder flattens all text nodes into a
simple list. RangeDifferencer (with the help of TextNodeComparator) then finds
the longest possible continuous list of changes, even though they should not
be continuous, because they are in a different parent block-element. When
visualizing the differences, all of them would then be inserted into the first
"common-parent", even though they all come from different parent blocks
elements.
I've solved this by letting DomTreeBuilder insert a dummy "separating" node
whenever a block starts or ends. This causes multiple RangeDifferences to be
created (i.e. one for all changes inside one block element) instead of one big
RangeDifference for all of them.
Additionally I improved the detection of "same" nodes in different DOM trees.
I also consider the node's position in the parent node, so that e.g. the
correct table cell (td) is found instead of the very first with the same
attributes.
Cheers,
Carsten

Hi,
i am facing one issue while comparing HTML using daisydiff.
Seems to me that when i give simple two tables for comparison where difference
in data is in table columns then it throws additional column in o/p.Following
are steps to reproduce & attached screenshots of problem.
1: Give left side for comparison as
<table border=2><tr border=2><td border=2>column1</td><td
border=2>column2</td><td border=2>column3</td></tr><tr border=2><td
border=2>1</td><td border=2>2</td><td border=2>3</td></tr></table>
2: Give right side for comparison as
<table border=2><tr border=2><td border=2>column1</td><td
border=2>column2</td><td border=2>column3</td></tr><tr border=2><td
border=2>1</td><td border=2>22</td><td border=2>3</td></tr></table>
observe difference is in 2nd column's data for left side its 2 & for right its
22
What is the expected output? What do you see instead?
This results in addition of column (td) for final data which disturbs whole UI.
Expected output is such that either this should add additional column in header
columns or it should put difference data in single column
What version of the product are you using? On what operating system?
daisydiff 1.1 & Windows XP
Please provide any additional information below.
Attaching Screenshots for reference, this shift in column cuases large
usability issue

Hi,
currently, daisydiff only supports comparing one revision of a file with another
revision. One revision will be regarded as the "old" version, the other as the
"new" version. Content overwritten by the new version will be displayed in
red, strike-through, the new content is displayed in green.
This works well if the history of a file is linear and the file cannot be edited
concurrently by multiple persons. With revision control systems, you typically
have three versions to compare:
- the revision that was checked out (ancestor)
- the revision with the local changes
- the current remote revision in the revision control system
In this case, the changes to be displayed are always against the ancestor, so
there may be "old" and "new" changes created by the local revision, as well as
"old" and "new" changes created by the current remote revision. These together
can lead to "conflicting" changes.
Attached is an initial (working) patch for daisydiff to support this scenario.
3-way comparison is already supported by org.eclipse.compare, only daisdiff
needed some additional things. I implemented this against daisydiff 1.1, but
ported it to trunk.
Some constraints with the current version:
- 3-way comparison is currently only available by API (i.e. HTMLDiffer.diff() --
should probably also be added to the Differ interface at least)
- conflicting changes are reported as new and old changes, although most of the
code for conflict detection and formatting is already there
I'd appreciate any feedback.
Cheers,
Carsten

What steps will reproduce the problem?
Create 2 very simple files and diff them (files attached, but also given here
due to their simplicity; each line is its own file):
<p>foo</p><p>bar</p>
<p>foo</p><p>baz</p>
What is the expected output? What do you see instead?
The expected output would be to find the first P tag copied verbatim (as there
have been no changes in it) and some diff markup in the second P tag. Instead,
both P tags contain diff markup tags - daisydiff claims that the string bar was
removed from the FIRST p and inserted into the second one (when it was in fact
removed from the SECOND one).
What version of the product are you using? On what operating system?
Tried both daisydiff 1.2 as well as latest SVN trunk version. OpenJDK 1.6.0_24
on OpenSUSE.
Please provide any additional information below.
I'm trying to instruct daisydiff to ignore certain trivial changes via
appropriate XSL templates and this bug is getting in my way.

What steps will reproduce the problem?
I have a non-valid HTML document that crashes the diff (but NekoHTML can
process it). Here is a very simplified version of it:
<html>
<body>
<a href="http://example.org"123></a>
</body>
</html>
Those 123 at the end make DaisyDiff crash. If the extra text does not start
with a number (e.g. the HTML5 standalon attribute 'required') then everything
is OK.
What is the expected output? What do you see instead?
The expected output would probably be to ignore that invalid attribute.

I've been performance testing DaisyDiff on some large diffs and have made a few
speedups. I'm working on a local fork, but would obviously like to keep it as
close to the official version as possible.
I've attached a patch of what I've done and I'll describe it too:
1) getParentTree was very inefficient. For a node of depth D it would create
D - 1 lists of ancestors of lengths D-1 -> 0, and add each list's contents to
the one bigger than it. I've rewritten it to create a single list and then
reverse it. There are numerous other ways to rewrite it but this one's fairly
simple.
2) The dominating performance problem is that the AncestorComparator does lots
of work. I'm afraid I don't understand how the differ works well enough to
stop it doing so many comparisons, but I've done some work to make the
comparisons faster.
* I've made the Node store a reference to root, so that getting the root node
doesn't require traversing through all the ancestors. It means that whenever a
Node has its parent changed, the root needs to be updated on that node and all
its children. I've added that to setParent and from my limited testing this
seems to be a significant net-win.
* I've written a method to compare an AttributeMap's content with an Attributes
object, which cuts down on the amount of calls to constructing an AttributeMap.
I can see the advantage of having one AttributeMap to look up attributes by
name rather than index, but one or other set of Attributes still needs to be
iterated over, so there's no need to have two of them.
* I've added an IdentityMap of Attributes -> Boolean in TagNode. This prevents
the need to retest whether the TagNode's Attributes are equal to another
TagNode's Attributes. This happens a *lot* apparently, and I suspect there's a
better fix to be made to prevent the checks being performed at all.
3) the DomTreeBuilder was calling inPre a lot, which was a fairly
time-consuming thing to do since each inPre requires a traversal through to the
pre tag or the root node. I've made the DomTreeBuilder simply track whether or
not it is within a pre-tag rather than delegating that work to the current node
and its tree.
I'm wondering whether one of the committers has an existing set of test data to
use for performance testing, as I'd love to make sure I haven't made any known
pathalogical cases worse instead of better. On the comparison one of our users
encountered these changes reduce the time spent diffing by about 25%.
I tried setting up an IdentityHashMap to track equality tests of the whole
TagNode instead of the AttributeMaps, and this was slightly more effective but
since TagNodes can theoretically change their parents and thus the outcome of
equals, this seemed unsafe.
