RE: [VFS] Could the HDFS connector work with MapR systems?

[Gary Gregory]

I've not seen VFS used in this configuration before. You could try updating to 
the current HDFS jar files.

Subject: [VFS] Could the HDFS connector work with MapR systems? 

Hi all,
    I'm using Commons VFS 2.1 along with the HDFS connector and 
everything is working brilliantly ... until, that is, trying to access HDFS on 
a MapR system.  Then I get things like null host name exceptions and the like.  
So, anyone have any idea whether the HDFS connector even COULD work against 
MapR?  And if not, anyone tried to build a MapR connector to Commons VFS 2.1?

Thanks in advance,
~Roger Whitcomb

Re: [vfs] HDFS provider

[Gary Gregory]

HDFS support was added after 2.0. You'll need to checkout the sources and
build a 2.1 snapshot.

Thank you for your understanding and help. We are all volunteers short on
time.

You might want to submit a 1.x patch in case an RM decides to push out a
release. That would grease the wheels a bit. Just in case...

[ANNOUNCEMENT] Apache Commons CSV 1.4

[Gary Gregory]

The Apache Commons team is pleased to announce the release of Apache
Commons CSV 1.4.

The Apache Commons CSV library provides a simple interface for reading and
writing CSV files of various types.

The main changes are the addition of a few APIs to make low-GC use-cases
possible.

Details of all changes in 1.4 can be found in the changelog:

http://commons.apache.org/proper/commons-csv/changes-report.html

1.4 is fully binary compatible to the last release. No client code changes
are required to migrate from version 1.3 to 1.4. The minimum required JDK
version for this release is 1.6.

Source and binary distributions are available for download from the Apache
Commons download site:

http://commons.apache.org/proper/commons-csv/download_csv.cgi

When downloading, please verify signatures using the KEYS file available at

http://www.apache.org/dist/commons/KEYS

Alternatively the release can be fetched from Maven Central:

  org.apache.commons
  commons-csv
  1.4


For complete information on Commons CSV, including instructions on how to
submit bug reports, patches, or suggestions for improvement, see the Apache
Commons Validator website:

http://commons.apache.org/proper/commons-csv/

Have fun!
Gary Gregory, on behalf of the Apache Commons Community

Re: [vfs] commons-vfs2-sandbox-2.1 is missing from Maven Central Repository

[Gary Gregory]

Yeah, I think sandbox code is just that, play things not fit for release,
due to licensing or other reasons.

You'd have to build it yourself and then deploy it to your own
repository(ies).

Re: [fileupload] UTF-8 encoding issue

[Gary Gregory]

I can see that
in org.apache.commons.fileupload.FileUploadBase.getBoundary(String) we have:

  boundary = boundaryStr.getBytes("ISO-8859-1");

Should that be:

  boundary = boundaryStr.getBytes(headerEncoding);

?

You can provide a diff file and attach it to a JIRA as a feature request.
Or, you can create a PR on GitHub. Unless you see mocks in the test
sources, we do not have them ;-) I do not recall seeing such mocks. Feel
free to come up with a design that is best for the community to understand
and maintain.

Hi Hege,

It all depends on an Apache Committer willing to volunteer and take the
time. This is the right place to ask :-)

Then maybe we need to document the fact that our code is still based on the
old RFC (is it?) and that we welcome contributions to modernize to the new
RFC...

Re: CLI2 - latest download link

[Gary Gregory]

The latest version of CLI is 1.4 which you can find here
https://commons.apache.org/proper/commons-cli/download_cli.cgi and in Maven
repositories.

There is no CLI 2.0 release, you may or may not find old 2.0-SNAPSHOT
builds in some Maven repositories.

Re: [CSV] Record Separator query

Hi Nitin,

You _tell_ the parser what record separator to use, the parser does not
tell you.

If you look at the Javadoc or the code for CSVFormat.RFC4180 you will see
that this format uses CR LF.

Use the button provided by GitHub to copy the repo URL to the clipboard,

There is no one currently slated to volunteer to RM the release. Good time

Do have a committer here willing to volunteer to release Commons CSV 1.5?

Re: [CSV] CSVMutableRecord

[Gary Gregory]

Hi All:

Should we consider adding put(int,Object) and put(String, Object) to the
current CSVRecord class?

I think we've kept the design as YAGNI as possible... :-)

How does that work when you want to change more than one value?

Re: [CSV] CSVMutableRecord

[Gary Gregory]

That looks odd to me. What comes up for me is the use case where I want to
ETL a file of 10,000,000 records and update, say, one column. If am forced
to create a brand new record for every record read, that would be a shame.

If I had a mutable record, I could just keep on updating it and using it to
write each row. Read record, update it, write record. No extra memory
needed.

Either we can make the current record mutable (what's the harm?) or we can
make the parser serve out mutable records based on a config setting. This
could be a subclass of CSVRecord with the extra method I proposed.

Thoughts?

Interesting idea!

But I think I like the idea of a subclass better if we are going to split
the behavior b/w mutable and immutable.

For my money and the KISS principle, I would just add the put method in
CSVRecord.

Saying that making record mutable is "breaking" is a bit unfair when we do
NOT document the mutability of the class in the first place.

Re: [CSV] Record Separator query

[Gary Gregory]

Hi Bruno,

I think it is fine to proceed with a release for 1.5. The code seems stable
to me now. The mutable record issue does not sound settled and fully baked
to me. I like RERO and since you've kindly volunteered to RM this release,
I'd rather not break your stride.

Re: [VFS] How to override a FileContent / FileContentInfo provider for an existing filesystem?

Hi Carl,

Do you mean org.apache.commons.vfs2.impl.DefaultFileContentInfo
and org.apache.commons.vfs2.impl.FileContentInfo?

Ralph, do have issue as to make this pluggable?

Re: [VFS] How to override a FileContent / FileContentInfo provider for an existing filesystem?

[Gary Gregory]

Hi Carl,

WRT DataSource, this is a JDBC interface, which does not seem appropriate
for a file system. Or do you mean javax.activation.DataSource. Apache
Commons VFS was started a long time ago and not adapted to newer JREs in
this area (obviously.)

Re: [VFS] How to override a FileContent / FileContentInfo provider for an existing filesystem?

I'm curious at what Ralph thinks. You could consider providing a PR to add
the feature to make the class pluggable and see how much code that
touches...

Unfortunately, it's more complicated than that. We have a release process
that requires a release manager from our team to volunteer and jump through
a bunch of hoops.

[ANNOUNCEMENT] Apache Commons Lang 3.7

[Gary Gregory]

The Apache Commons community is happy to announce the availability of
Apache Commons Lang 3.7.

Apache Commons Lang provides helper utilities for the java.lang API,

contention (PR #296.) Thanks to Chas Honton.
o LANG-1360: Add methods to ObjectUtils to get various forms of class names
in a null-safe manner Thanks to Gary Gregory.

Fixed Bugs:
o LANG-1362: Fix tests DateUtilsTest for Java 9 with en_GB locale Thanks to
Stephen Colebourne.
o LANG-1365: Fix NullPointerException in isJavaVersionAtLeast on Java 10,
add SystemUtils.IS_JAVA_10, add JavaVersion.JAVA_10 Thanks to Gary Gregory.
o LANG-1348: StackOverflowError on TypeUtils.toString(...) for a generic
return type of Enum.valueOf Thanks to mbusso.
o LANG-1350: ConstructorUtils.invokeConstructor(Class, Object...)
regression Thanks to Brett Kail.

The Apache Commons BCEL team is pleased to announce the release of Apache
Commons BCEL 6.2 with better Java 9 support!

The Byte Code Engineering Library (BCEL) is intended to give users a
convenient way to analyze, create, and manipulate compiled .class files.
Classes are represented by objects containing all the symbolic information
of the given class: methods, fields and byte code instructions.

Experimental Java 9 Support.

FIXED BUGS:
===

o BCEL-294: Incorrect comment in StackMap.java Thanks to Mark Roberts.
o BCEL-296: Incorrect comment in several classes. Thanks to Mark Roberts.
o BCEL-295: Fix local variable live range length; add test case. Thanks to
Mark Roberts.
o BCEL-300: org.apache.bcel.classfile.ClassFormatException: Invalid byte
tag in constant pool: 19.
o BCEL-301: org.apache.bcel.classfile.ClassFormatException: Invalid byte
tag in constant pool: 20.

[ANNOUCEMENT] Apache Commons Pool 2.5.0

[Gary Gregory]

The Apache Commons Pool team is pleased to announce the release of Apache
Commons Pool 2.5.0.

Apache Commons Pool provides an object-pooling API and a number of object
pool implementations.
Version 2 contains a completely re-written pooling implementation compared
to the 1.x series.
In addition to performance and scalability improvements, version 2 includes
robust instance
tracking and pool monitoring. Version 2 requires JDK level 1.6 or above.

No client code changes are required to migrate from versions 2.4.x to
version 2.5.0.
Users of version 1.x should consult the migration guide on the Commons Pool
web site.

NOTE: The MBean interfaces (DefaultPooledObjectInfoMBean,
GenericKeyedObjectPoolMXBean
  and GenericKeyedObjectPoolMXBean) exist only to define the attributes
and methods
  that will be made available via JMX. They must not be implemented by
clients as
  they are subject to change between major, minor and patch version
releases of
  Commons Pool. Clients that implement any of these interfaces may not,
therefore,
  be able to upgrade to a new minor or patch release without requiring
code
  changes.

Changes in version 2.5.0 include:

New features:
o POOL-332:  ObjectPool and KeyedObject pool should extend Closeable.
o POOL-335:  Make abandoned logging stack trace requirements configurable.
This also reverts
 the default behavior introduced by POOL-320.


Changes:
o POOL-331:  Update from Java 6 to 7.
o POOL-333:  Update optional dependency asm-util from 5.2 to 6.0.
o POOL-334:  org.apache.commons.pool2.impl.ThrowableCallStack.Snapshot is
missing serialVersionUID.


For complete information on Apache Commons Pool, including instructions on
how to submit bug reports,
patches, or suggestions for improvement, see the Apache Apache Commons Pool
website:

Enjoy!

[ANNOUNCEMENT] Apache Apache Commons DBCP 2.2.0

[Gary Gregory]

The Apache Commons DBCP team is pleased to announce the release of Apache
Apache Commons DBCP 2.2.0.

Apache Commons DBCP software implements Database Connection Pooling.

This is a minor release, including bug fixes and enhancements.

Changes in this version include:

New features:
o DBCP-451:  Add constructor DriverManagerConnectionFactory(String).
o DBCP-462:  Refactoring to prepare for a future patch to enable pooling of
all
 prepared and callable statements in PoolingConnection. Thanks
to Keiichi Fujino.
o DBCP-458:  Make it simpler to extend BasicDataSource to allow sub-classes
to
 provide custom GenericObjectPool implementations. Thanks to
Adrian Tarau.
o DBCP-474:  Enable pooling of all prepared and callable statements
 inPoolingConnection. Thanks to Keiichi Fujino.

Fixed Bugs:
o DBCP-481:  Update Apache Commons Pool from 2.4.2 to 2.5.0. Thanks to Gary
Gregory.
o DBCP-454:  OSGi declarations contain multiple import headers for
javax.transaction. Thanks to Philipp Marx, Matt Sicker.
o DBCP-478:  Wrong parameter name in site documentation for BasicDataSource
Configuration Parameters. Thanks to nicola mele.
o DBCP-452:  Add jmxName to properties set by BasicDataSourceFactory.  This
 enables container-managed pools created from JNDI Resource
 definitions to enable JMX by supplying a valid root JMX name.
o DBCP-446:  NullPointerException thrown when calling
ManagedConnection.isClosed(). Thanks to Gary Gregory, feng yang, Euclides
M, Phil Steitz.
o DBCP-444:  InvalidateConnection can result in closed connection returned
by getConnection.
o DBCP-449:  Complete the fix for DBCP-418, enabling PoolableConnection
class to load in environments
 (such as GAE) where the JMX ManagementFactory is not
available. Thanks to Grzegorz D.
o DBCP-455:  Ensure that the cacheState setting is used when statement
pooling is
 disabled. Thanks to Kyohei Nakamura.
o DBCP-453:  Ensure that setSoftMinEvictableIdleTimeMillis is used when
working with
 BasicDataSource. Thanks to Philipp Marx.
o DBCP-456:  Correct the name of the configuration attribute
 softMinEvictableIdleTimeMillis. Thanks to Kyohei Nakamura.
o DBCP-472:  Avoid potential infinite loops when checking if an
SQLException is fatal
 for a connection or not.
o DBCP-468:  Expand the fail-fast for fatal connection errors feature to
include
 managed connections.
o DBCP-463:  Correct a typo in the method name
 PoolableConnectionFactory#setMaxOpenPreparedStatements. The
old method
 remains but is deprecated so not to break clients currently
using the
 incorrect name.
o DBCP-459:  Ensure that a thread's interrupt status is visible to the
caller if the
 thread is interrupted during a call to
 PoolingDataSource.getConnection().
o DBCP-457:  When using a BasicDataSource, pass changes related to the
handling of
 abandoned connections to the underlying pool so that the pool
 configuration may be updated dynamically.

Re: Error in commons collections4 Caused by java util ConcurrentModificationException

[Gary Gregory]

Just like it says on the Javadoc:
https://docs.oracle.com/javase/7/docs/api/java/util/ConcurrentModificationException.html

One piece of code must be reading while another is writing on the
collection.

Re: Error in commons collections4 Caused by java util ConcurrentModificationException

[Gary Gregory]

Hi,

The Commons Collection code throws ConcurrentModificationException when it
detects error conditions. The JRE collections do the same (the ones that
are not thread-safe.)

That does not help much, sorry. I'm afraid you are left with a tricky
debugging session.

It is _possible_ that there is a bug in Commons Collections of course. In
which case, an analysis or reproducible test case would be most welcome.

Also, please make sure you are using the latest version: 4.1.

Thank you,
Gary

Are we sure that our shutdown logic always cleans up the thread-pool no

Re: [primitives] I would like to contribute two methods to the array lists

[Gary Gregory]

Hi Michael,

I'm not sure how alive the primitives component is, but the best way to
contribute new methods like these is to provide a GitHub PR with unit
tests. It is very unlikely that new code like this would be accepted
without unit tests and decent code coverage. But, this component is not
mirrored on GitHub so you'll have to do it the old fashioned way:
- Create a JIRA
- Attach a patch in unified diff format for your new methods and their unit
tests

Thank you!
Gary

I do not think this is a question I, or anyone here, can answer
generically. I can read between that lines that you must feel frustrated
and I certainly empathize with that. I think you might want to debug your
application and come up with some parameters for us to start helping you. A
reproducible example is always best but I understand it might be hard to
provide in this particular case.

Re: [VALIDATOR] Update of packages used by Validator?

[Gary Gregory]

I just updated in svn trunk the dependency Apache Commons BeanUtils from
1.9.2 to 1.9.3.

My hope is to see the community:

- Release Apache Commons Release Maven Pplugin 1.1 (this one is DONE :-)
- Release Apache Commons Parent 45 (referencing  Apache Commons Release
plugin 1.1)
- Release other Apache Commons components like Validator.

[ANNOUNCEMENT] Apache Commons Pool 2.6.0 released.

[Gary Gregory]

The Apache Commons Pool team is pleased to announce the release of Apache
Commons Pool 2.6.0.

Apache Commons Pool provides an object-pooling API and a number of object
pool implementations.
Version 2 contains a completely re-written pooling implementation compared
to the 1.x series.
In addition to performance and scalability improvements, version 2 includes
robust instance
tracking and pool monitoring.

- Version 2.6.0 requires Java 7 or above.
- Version 2.5.0 requires Java 7 or above.
- Version 2.0 requires 6 or above.

No client code changes are required to migrate from versions 2.0-2.3 to
version 2.4.3.
Users of version 1.x should consult the migration guide on the Commons Pool
web site.

NOTE: The MBean interfaces (DefaultPooledObjectInfoMBean,
GenericKeyedObjectPoolMXBean
  and GenericKeyedObjectPoolMXBean) exist only to define the attributes
and methods
  that will be made available via JMX. They must not be implemented by
clients as
  they are subject to change between major, minor and patch version
releases of
  Commons Pool. Clients that implement any of these interfaces may not,
therefore,
  be able to upgrade to a new minor or patch release without requiring
code
  changes.

This is a maintenance release.

Changes in version 2.6.0 include:

Fixed Bugs:
o POOL-337:  Ensure cancelled eviction tasks are removed from scheduler.
Thanks to Reinald Verheij.
o POOL-338:  GenericObjectPool constructor may throw an exception under
OSGi. Thanks to Michael C, Gary Gregory.
o POOL-324:
org.apache.commons.pool2.impl.GenericObjectPool.getFactoryType() throws
java.lang.ClassCastException. Thanks to Jay Xu, Gary Gregory.
o POOL-344:  Delete repeated call startEvictor. Thanks to Yulin Wang.

Changes:
o POOL-336:  GenericObjectPool's borrowObject lock if create() fails with
Error. Thanks to Wolfgang Glas.
o POOL-339:  Update optional library cglib from 3.2.5 to 3.2.6.
o POOL-341:  Update optional library asm-util from 6.0 to 6.1.1.
o POOL-342:  Update optional library asm-util from 6.1.1 to 6.2.

Note that Clirr reports one warning:
"Value of field DEFAULT_EVICTION_POLICY_CLASS_NAME is no longer a
compile-time constant."
The value is initialized as "public static final String
DEFAULT_EVICTION_POLICY_CLASS_NAME = DefaultEvictionPolicy.class.getName();"
The value should not change from one run to the next.

[ANNOUCEMENT] Apache Commons DBCP Version 2.5.0

[Gary Gregory]

The Apache Commons DBCP team is pleased to announce the release of Apache
Apache Commons DBCP 2.5.0-SNAPSHOT.

Apache Commons DBCP software implements Database Connection Pooling.

This is a minor release, including bug fixes and enhancements and requires
Java 8 to support JDBC 4.2.

Changes in this version include:

New features:
o DBCP-506:  Support JDBC 4.2. Thanks to Gary Gregory.
o DBCP-479:  Support default schema in configuration. Thanks to Guillaume
Husta, Gary Gregory.

Fixed Bugs:
o DBCP-508:  Prepared statement keys should take a Connection's schema into
account. Thanks to Gary Gregory.
o DBCP-512:  Avoid exceptions when closing a connection in mutli-threaded
use case. Thanks to Gary Gregory.

Changes:
o DBCP-505:  Update Java requirement from version 7 to 8. Thanks to Gary
Gregory.
o DBCP-427:  Examines 'SQLException's thrown by underlying connections or
statements for fatal (disconnection) errors. Thanks to Vladimir Konkov,

o DBCP-507:  Change default for fail-fast connections from false to true.
Thanks to Vladimir Konkov, Phil Steitz, Gary Gregory.
o DBCP-504:  Increase test coverage. Thanks to Bruno P. Kinoshita.
o DBCP-510:  Update Apache Commons Pool from 2.5.0 to 2.6.0. Thanks to Gary
Gregory.

Note that Clirr incorrectly reports one binary incompatible change because
it is not aware of Java 8 and default methods:
[ERROR] 7012: org.apache.commons.dbcp2.BasicDataSourceMXBean: Method
'public java.lang.String getDefaultSchema()' has been added to an interface
