[jira] [Created] (COMPRESS-133) Mention Debian/Ubuntu packages in AR format documentation
Mention Debian/Ubuntu packages in AR format documentation
-
Key: COMPRESS-133
URL: https://issues.apache.org/jira/browse/COMPRESS-133
Project: Commons Compress
Issue Type: Improvement
Components: Archivers
Reporter: Bear Giles
Priority: Trivial
The documentation for the AR format can/should mention that it is the basis for
Debian/Ubuntu packages. A .deb file is actually an AR file with three elements:
_debian-binary_: version number ("2.0")
_data.tar.gz_: compressed tarball containing the package's files
_control.tar.gz_: compressed tarball containing the package's metadata
(information, installation and removal scripts, etc.)
People will normally want to use the Debian package management tools but it's
nice to know that we can access the 'original' content if necessary.

[jira] [Created] (COMPRESS-132) Add support for unix dump files
Add support for unix dump files --- Key: COMPRESS-132 URL: https://issues.apache.org/jira/browse/COMPRESS-132 Project: Commons Compress Issue Type: Improvement Components: Archivers Reporter: Bear Giles Priority: Minor I'm submitting a series of patches to the ext2/3/4 dump utility and noticed that the commons-compress library doesn't have an archiver for it. It's as old as tar and fills a similar niche but the later has become much more widely used. Dump includes support for sparse files, extended attributes, mac os finder, SELinux labels (I think), and more. Incremental dumps can capture that files have been deleted. I should have initial support for a decoder this weekend. I can read the directory entries and inode information (file permissions, etc.) but need a bit more work on extracting the content as an InputStream. -- This message is automatically generated by JIRA.

You overlooked that two different artifacts are in use: commons-beanutils and
commons-beanutils-core. And if commons-beanutils-core is first in classpath the
rest of the classes are loaded from commons-beanutils. I can imagine that at
some point problems may arise.

I agree. A new class would be best. Now that I am more familiar with commons
math, my code should be changed to use double primitive types instead of Double
objects. That use seems more consistent with other descriptive statistics in
math.

[jira] [Commented] (MATH-592) Convenience Methods for Retrieving the Start and End Points of a SubLine

However, this class is really a speciliazed one for internal purposes in PolygonsSet (there is an horrible hack with OrderedTuple). I guess I may simplify this class to hold only the start and end point, make it public (it is package protected) and use it in the new API, and add an internal OrderedSegment (and OrderedSegmentBuilder) inside PolygonsSet. I'll resolve this issue when this will be ready. Please be aware that due to this change, you will have to slightly adapt your code. > Convenience Methods for Retrieving the Start and End Points of a SubLine > > > Key: MATH-592 > URL: https://issues.apache.org/jira/browse/MATH-592 > Project: Commons Math > Issue Type: New Feature >Affects Versions: 3.0 >Reporter: Curtis Jensen >Priority: Minor > Labels: Geometry, math > Fix For: 3.0 > > Original Estimate: 24h > Remaining Estimate: 24h > > For convenience, it would be helpful to have methods in the SubLine class to > retrieve the start and end points of the SubLine. -- This message is automatically generated by JIRA.

Oliver Heger commented on CONFIGURATION-451:
Not sure whether I understand your point. There is no need to have both
versions of commons-beanutils in the classpath. The transitive dependency to
version 1.7.0 is overridden by the one specified in the pom. So the maven
classpath ends up with only version 1.8 included. Just do a {{mvn
dependency:copy-dependencies}}. This command puts all dependencies currently
used in a directory. There is only the newest version of beanutils contained.
In your project you also should have *only* version 1.8 of beanutils in the
classpath. Commons Configuration is compatible with it. You can use all new
features of this version in your project.

A constructor using two endpoints has also been added. Could you check if the API suits your needs ? The new method is called getSegments and returns a list of Vector2D arrays. Each element of the list correspond to one segment of the subline, and is contains exactly two points: a start point at index 0 and an endpoint at index 1. Perhaps a dedicated class with a getStart() and getEnd() methods would be better than a two points array. Provisions have been taken for half-infinite or full lines (first and last points will have infinite coordinates with the right sign). > Convenience Methods for Retrieving the Start and End Points of a SubLine > > > Key: MATH-592 > URL: https://issues.apache.org/jira/browse/MATH-592 > Project: Commons Math > Issue Type: New Feature >Affects Versions: 3.0 >Reporter: Curtis Jensen >Priority: Minor > Labels: Geometry, math > Fix For: 3.0 > > Original Estimate: 24h > Remaining Estimate: 24h > > For convenience, it would be helpful to have methods in the SubLine class to > retrieve the start and end points of the SubLine. -- This message is automatically generated by JIRA.

Phil Steitz commented on MATH-449:

I am leaning toward just adding a new class called StorelessCovariance and
similar for StorelessPearsonsCorrelation that just provide bivariate
statistics. You will notice that in fact the PersoansCorrelation class
delegates to SimpleRegression which does the bivariate computation
"storelessly" already.
Thanks for adding the comment and for the contribution!

I've added the comment to the code. If you have better language for the
comment, pleas send it to me and I will include it.
Do you have any suggestions for how to best integrate this code into the
Covariance class? It's not so easy given that the class allows for computation
of a covariance matrix.

Can you please either add a comment indicating the code pasted to the ticket is
granted for inclusion under terms of the ASL or add it as an attachment and
check the "for inclusion" box? Also, some unit tests would be great, including
validation tests against the stored data version.

[jira] [Updated] (LANG-706) Create a MutableNumber interface with methods common to all the mutable numbers
[
https://issues.apache.org/jira/browse/LANG-706?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Juan Carlos Estibariz updated LANG-706:

Description:
With this interface it would be possible to perform generic operations on
mutable numbers without worrying about the specific type, e.g.
{code}
// these two could be created in a different methods
MutableNumber m = new MutableDouble();
Number n = ...;
// this would do the right thing
m.add(n);
{code}

(I'm not just making this up, I have a real use case and I had to create all
the classes myself)

[jira] [Commented] (MATH-594) AdamsMoultonIntegrator documentation whitespace fix
[ https://issues.apache.org/jira/browse/MATH-594?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13049678#comment-13049678 ] Luc Maisonobe commented on MATH-594: Only the Adams integrators are experimental. There was another integrator (BDF, Backward Differential Formula) that was still more experimental but in fact it was not included in the library (it may be included once Adams integrators are OK, as it shares some code with them, as a multi-step integrator). The good integrators I recommend are Dormand-Prince 8(5,3) and Gragg-Bulirsch-Stoer. They are very efficient and very accurate. You are right, we should display the status of Adams integrators more prominently. The best thing however is really to remove this "experimental" status and have these integrators as suitable for production than the other ones. If we can't achieve this, we'll put a warning in the documentation. > AdamsMoultonIntegrator documentation whitespace fix > --- > > Key: MATH-594 > URL: https://issues.apache.org/jira/browse/MATH-594 > Project: Commons Math > Issue Type: Improvement >Reporter: Dennis Hendriks >Priority: Trivial > Labels: documentation, patch > Fix For: 3.0 > > Attachments: adams-moulton-integrator-docu-whitespace-fix.patch > > -- This message is automatically generated by JIRA.
