Changes from Ant 1.8.1 TO Ant 1.8.2
===================================
Changes that could break older environments:
-------------------------------------------
* Prior to Ant 1.8.0 the <copy> task and several other tasks would
overwrite read-only destination files. Starting with 1.8.0 they
would only do so under special circumstances. Ant 1.8.2 now
consistently won't replace a read-only file by default. The same is
true for a number of other tasks.
The <copy>, <move> and <echo> tasks now have a new force attribute
and <concat> has a new forceReadonly attribute that can be used to
make the task overwrite read-only destinations.
Bugzilla Report 49261.
* Removed ant-nodeps.jar; it is now merged into ant.jar.
* DOMElementWriter#encode used to employ special code before encoding
ampersands so that { remained { rather than being turned
into &#123;. This is no longer the case, ampersands will now
be encoded unconditionally.
Also DOMElementWriter#encodeData will treat CDATA sections containing a
literal "]]>" sequence different now - it will split the CDATA
section between the second "]" and ">" and create two sections.
This affects <echoxml> task as well as the XML logger or JUnit
formatter where ampersands will now always get encoded.
In addition DOMElementWriter will now replace the characters \t, \r
and \n in attribute values by entity references.
Bugzilla Report 49404.
* The list elements returned by ProjectHelper#getExtensionStack are
now String arrays of length 3 rather than 2 in order to support the
onMissingExtensionPoint attribute.
Bugzilla Report 49473.
* When using <property file="..." prefix="..."/> properties defined
inside the same file will only get used in expansions if the ${}
reference uses the same prefix. This is different from Ant 1.8.1
but is the same behavior Ant 1.8.0 and earlier exhibited.
A new attribute prefixValues can be used to re-enable the behavior
of Ant 1.8.1.
Bugzilla Report 49373.
* The files and directories used by Git, Mercurial and Bazaar to
store their information are now excluded by the defaultexcludes.
Bugzilla Report 49624.
* The <junit> task no longer generates TestListener events - which
have been introduced in ant 1.7.0 - by default. The task has a new
attribute enableTestListenerEvents and a new "magic" property
ant.junit.enabletestlistenerevents has been added that can be used
to reinstate the old behavior.
Fixed bugs:
-----------
* hostinfo now prefers addresses with a hostname over addresses without
a hostname, provided the addresses have the same scope.
For local lookup, no IP address will be put in NAME / DOMAIN anymore.
For remote lookup, if a host name was provided and only an IP address is
found, the IP address will no longer overwrite the host name provided to the
task.
Bugzilla Report 49513
* mmap-based file copy problems under JDK 1.4 on Linux.
Bugzilla Report 49430.
* The Sun JVM tries to mmap the entire file during a copy.
For large files this is not feasible.
We now explicitly request to copy at most 16 MiB per request.
Bugzilla Report 49326.
* DemuxInputStream.read() should return unsigned values
Bugzilla Report 49279.
* The MIME mailer ignored the port parameter when using SSL.
Bugzilla Report 49267.
* <xslt> ignored the classpath when using the default TraX processor.
Bugzilla Report 49271.
* <checksum>'s totalproperty only worked reliably if the same file
name didn't occur inside more than one directory.
Bugzilla Report 36748.
* <ftp> could fail to download files from remote subdirectories under
certain circumstances.
Bugzilla Report 49296.
* <junit> will now produce better diagnostics when it fails to delete
a temporary file.
Bugzilla Report 49419.
* Ant would often scan directories even though there were known to
only hold excluded files when evaluating filesets. This never
resulted in wrong results but degraded performance of the scan
itself.
Bugzilla Report 49420.
* <javac> failed for long command lines on OS/2.
Bugzilla Report 49425.
* <junitreport> did not handle encodings well for stdout/stderr.
Bugzilla Report 49418.
* <junit> could issue a warning about multiple versions of Ant on the
CLASSPATH if two CLASSPATH entries differed in case on a
case-insensitive file system.
Bugzilla Report 49041.
* The <restrict> resource collection was checking every resource even if
we actually just want the first one, like in the example of use of
resourcelist in the documentation (getting the first available resource
from a mirror list).
* A race condition could lead to build failures if multiple <mkdir>
tasks were trying to create the same directory.
Bugzilla Report 49572.
* the toString() method of the Resources class - and thus any
${toString:} expansion of a reference to a <resources> element -
didn't iterate over its nested elements if it hadn't done so prior
to the toString invocation already.
Bugzilla Report 49588.
* <apply> in parallel mode didn't work together with a nested
<redirector> if maxparallel was <= 0 (the default) or no source
files matched.
Bugzilla Report 49594.
* <jar filesetmanifest="merge"> didn't work for manifests added via
<zipfileset>s that used the prefix or fullpath attributes.
Bugzilla Report 49605.
* <tempfile createfile="true"> would cause an error unless the prefix
attribute has been specified.
Bugzilla Report 49755.
* If forked, after finished <java> was still reading the input stream
for a bunch of characters, then stealing them from a following <input>.
Bugzilla Report 49119.
* Ant could be leaking threads for each forked process (started by
<exec>, <apply>, <java> or similar tasks) that didn't receive input
from a resource or string explicitly.
Bugzilla Report 49587.
* Project#setDefault threw an exception when null was passed in as
argument, even though the Javadoc says null is a valid value.
Bugzilla Report 49803.
* runant.py would swallow the first argument if CLASSPATH wasn't set.
Bugzilla Report 49963.
* <taskdef> failed to load resources from jar files contained in a
directory that has a "!" in its name.
Bugzilla Report 50007.
* ant.bat exit strategy improvements and issues
make the exit codes work in environments where 4NT or MKS are installed
Bugzilla Report 41039.
* <signjar> would fail if used via its Java API and the File passed
into the setJar method was not "normalized" (i.e. contained ".."
segments).
Bugzilla Report 50081.
* <delete> ignored <fileset>'s errorOnMissingDir attribute
Bugzilla Report 50124.
* <symlink> failed to close files when reading a list of symbolic
links from a properties file.
Bugzilla Report 50136.
* <parallel> could allow tasks to start executing even if a task
scheduled to run before them timed out.
Bugzilla Report 49527.
* If a <junit> batch with multiple tests times out Ant logs a message
about a test named Batch-With-Multiple-Tests since 1.8.0 but the
logic that determined the Java package of this pseudo-test has been
wrong.
Bugzilla Report 45227.
* <propertyfile> didn't preserve the original linefeed style when
updating a file.
Bugzilla Report 50049.
* <zip>'s whenEmpty behavior never consulted the non-fileset
resources so the task could fail even though resources have been
provided using non-fileset resource collections.
Bugzilla Issue 50115.
* ftp chmod could throw a NPE.
Bugzilla report 50217.
* The project help (-p option in the command line) will now print
the dependencies of the targets in debug mode (-d on the command
line)
Other changes:
--------------
* <concat>'s force attribute has been deprecated in favor of a new
overwrite attribute that is consistent with <copy>'s attribute
names.
* You can now specify a list of methods to run in a JUnit test case.
Bugzilla Report 34748.
* properties in files read because of the -propertyfile command line
option will now get resolved against other properties that are
defined before the project starts executing (those from the same or
earlier -propertfiles or defined via the -D option).
Bugzilla Report 18732.
* <pathelement>s can now contain wildcards in order to use wildcard
CLASSPATH entries introduced with Java6.
The wildcards are not expanded or even evaluated by Ant and will be
used literally. The resulting path may be unusable as a CLASSPATH
for Java versions prior to Java6 and likely doesn't mean anything
when used in any other way than a CLASSPATH for a forked Java VM.
Bugzilla Report 46842.
* A new attribute allows targets to deal with nonexistent extension
points, i.e. they can extend an extension-point if it has been
defined or silently work as plain targets if it hasn't. This is
useful for targets that get included/imported in different
scenarios where a given extension-point may or may not exist.
Bugzilla Report 49473.
* Ant now logs a warning message if it fails to change the file
modification time in for example when using <touch> or preserving
timestamps in various tasks.
Bugzilla Report 49485.
* ProjectHelpers can now be installed dynamically via the <projecthelper>
Ant task.
* <import> is now able to switch to the proper ProjectHelper to parse
the imported resource. This means that several kinds of different build
files can import each other.
* <copy tofile=""> now also works for non-filesystem resources.
Bugzilla Report 49756.
* The <linecontainsregexp> filter now supports a casesensitive
attribute.
* The <containsregexp> selector now supports casesensitive, multiline
and singleline attributes.
Bugzilla Report 49764.
* A new <cutdirsmapper> can be used like wget's --cut-dirs option to
strip leading directories from file names.
* <javah> now supports the GNU project's gcjh compiler.
Bugzilla Report 50149.
* <checksum> supports additional views of a file's path as elements
for a custom pattern.
Bugzilla Report 50114.
* JUnit XMLResultAggregator logs the stack trace of caught IO exceptions
in verbose runs.
Bugzilla Report 48836.
* StringUtils.parseHumanSizes() should turn parse failures into
BuildExceptions.
Bugzilla Report 48835.
* New task <bindtargets> to make a list of targets bound to some
specified extension point.
* Initial support for OpenJDK7 has been added.
* Ant now uses java.net.CookieStore rather than
java.util.ServiceLocator to detect whether the environment is a
Java 1.6 system. This means releases of gcj/gij at the time of
this release of Ant are detected as Java 1.5 and not 1.6.
Bugzilla Report 50256.
* It is now possible to write a compiler adapter for <javac> that
compiles sources with extensions other than .java (but that still
compile to .class files).
Bugzilla Report 48829.
* The performance of VectorSet#add(Object) has been improved which
should also benefit any operation that scans directories in Ant.
Bugzilla Report 50200.
Apache Ivy is a simple yet powerful dependency manager featuring
continuous integration, dependencies of dependencies management,
multiple repositories including ibiblio and high performance (use
of a local cache).
The ruby-ole library provides a variety of functions primarily for
working with OLE2 structured storage files, such as those produced by
Microsoft Office - eg *.doc, *.msg etc.
* msggrep: A '$' anchor in a regular expression now also matches the end of
the string, even if it does not end in a newline.
* Dependencies:
The libraries and programs are now linked with libunistring if this library
is already installed.
* Installation options:
The configure option --with-cvs is deprecated. The 'autopoint' program will
now use the 'git' program by default to compress its archive. If the
configure option --without-git is specified, 'autopoint' will not rely on
'git', but will instead rely on a locally installed a 3 MB large archive.
Changes 0.18:
* Runtime behaviour:
- On MacOS X and Windows systems, <libintl.h> now extends setlocale() and
newlocale() so that their determination of the default locale considers
the choice the user has made in the system control panels.
- On MacOS X systems, the gettext()/dgettext()/... functions now respect the
locale of the current thread, if a thread-specific locale has been set.
* PO file format:
There is a new field 'Language' in the header entry. It denotes the language
code (plus optional country code) for the PO file. This field can be used
by automated tools, such as spell checkers. It is expected to be more
reliable than looking at the file name or at the 'Language-Team' field in
the header entry.
msgmerge, msgcat, msgen have a new option --lang that allows to specify
this field. Additionally, msgmerge fills in this new field by looking at
the 'Language-Team' field (if the --lang option is not given).
* xgettext and PO file format:
For messages with plural forms, programmers can inform the translators
about the range of possible values of the numeric argument, like this:
/* xgettext: range: 0..15 */
This information 'range: 0..15' is stored in the PO file as a flag attached
to the message. Translators can produce better translations when they know
that the numeric argument is small.
* Colorized PO files:
msgattrib, msgcomm, msgconv, msgen, msgfilter, msggrep, msginit, msgmerge,
msgunfmt, msguniq, xgettext now have options --color and --style, like msgcat
has since version 0.17.
* msgmerge is up to 10 times faster when the PO and POT files are large.
This speedup was contributed by Ralf Wildenhues.
* msgcmp has a new option -N/--no-fuzzy-matching, like msgmerge has since
version 0.12.
* msgfilter now sets environment variables during the invocation of the
filter, indicating the msgid and location of the messge being processed.
* xgettext now can extract plural forms from Qt 4 programs. The recommended
xgettext command-line options for this case are:
--qt --keyword=tr:1,1t --keyword=tr:1,2c,2t --keyword=tr:1,1,2c,3t
* xgettext --language=GCC-source now recognizes also the format strings
used in the Fortran front-end of the GCC compiler, and marks them as
'gfc-internal-format'.
* autopoint can now be used to update several PO directories all together.
* Fixed typos & spelling errors.
Changes 2.032:
* IO::Uncompress::Base
- An input file that had a valid header, and so would allow
creation of the uncompression object, but was then followed by
corrupt data would trigger an infinite loop when using the
input line oprator.
* IO::Compress::Gzip
- XFL default settings for max compression & fastest algorithm were
the wrong way around. Thanks to Andrey Zholos for spotting this.
* IO::Compress::Base::Common
- Fixed precedence problem in parameter parsing code.
This package contains the runtime libraries for pcc, the Portable C
Compiler. On some platforms, these libraries are needed to compile code
with PCC.

supported UTF-8, ncurses line graphics, and ASCII. Also, enable
revision graph rendering by default.
Bug fixes:
- Fix ncurses 2.8 issue by passing non-zero column size to newwin(1).
- Fix opening of diffs when browsing branches.
tig-0.16.2
----------
Bug fixes:
- Fix regression causing empty tree view.
- Fix set_tabsize() compile error for older versions of ncurses.
tig-0.16.1
----------
Improvements:
- Add scroll-first-col action to jump to the first column. Bound to '|'
by default.
- Add 'status-untracked-dirs' option to ignore unknown directories
contents in the status view. On by default.
Bug fixes:
- Fix 'tig show <commit>' to show the provided commit.
- Fix problem with empty diff views when file specs were passed on the
command line.
- Fix segfault when starting tig in pager mode.
tig-0.16
--------
Incompatibilities:
- Encode everything internally as UTF-8. This can affect performance,
but should in general improve handling of character lengths etc.
Also, to properly handle UTF-8 environments use ncurses with wide
character support.
- The use of TIG_{MAIN,DIFF,LOG,TREE,BLOB}_CMD environment variables
has been deprecated. To allow configuration of the diff view,
TIG_DIFF_OPTS can be used.
Improvements:
- Plug several memory leaks.
- Command line arguments are split into diff, revision, and file
arguments and made available as %(diffargs), %(revargs), and
%(fileargs). Diff view will limit diffs using %(fileargs).
- Status view: update the file variable when a line is selected so
%(file) works as expected.
- Branch view: add %(branch) symbol providing access to the selected
branch.
- Branch view: add entry to browse all branches (uses git-log's --all
flag).
- Abbreviation of author names can now be configured and toggled.
- Mark detached heads with [HEAD].
- Add support for displaying dates in local time.
Bug fixes:
- Status view: fix usage from sub directories, which was broken by the
changes made to support blame view from sub directories.
- Fix text expansion to not truncate long lines
- Fix parsing of boolean show-date values.
- Fix relative date.
- Fix unbind to behave as if the keybinding was never defined.
- Fix unbind to also cover built-in run requests.
- Fix parsing of unknown keymap names.
- Blame view: fix parent blame to detect renames. It uses "previous"
line info from the blame porcelain output added in git version 1.6.3.
tig-0.15
--------
Incompatibilities:
- Setting the cursor color no longer automatically sets the text to
bold. The old 'lazy' behavior was a bug.
- Remove check for git-repo-config, which was officially deprecated in
git version 1.5.4. The configure script no longer depends on git
being installed.
Improvements:
- Provide the manual as a man page named tigmanual(7).
- Add ability to toggle between showing shorter dates (without time
info) and relative dates. Use 'D' to toggle between date formats.
- Show the active (instead of the default) keybindings in the help
view. Furthermore, honor the keymap when suggesting actions in the
help messages.
- Add branch view for choosing which branch to display in the main
view. Bound to 'H' by default.
- Tree view: show entry to parent directory ('..') when running from
subdirectory.
- Tree view: sort entries by name, date or author. Toggling is bound to
'i' by default, with 'I' controlling whether or not to sort in
ascending order.
- Make height of the lower view in a split view configurable by setting
the 'split-view-height' variable to a number or a percentage.
Defaults to 2/3 of the total view height.
- Allow multiple text attributes for color commands:
color cursor white blue underline bold
Bug fixes:
- Blame view: fix loading of blame data when opened from the tree view
and CWD is not the repo root. (Debian bug 540766)
- Tree view: fix searching.
tig-0.14.1
----------
Improvements:
- Status view: improve "on branch" information inspired by the prompt
code in git's bash completion script.
- Colors for 256-capable terminals can be specified as colorN.
- Entering a number in the prompt will jump to that line number.
- Handle core.worktree by setting GIT_DIR and GIT_WORK_TREE.
- Make behavior of horizontal scrolling configurable by setting the
'horizontal-scroll' variable to a number or a percentage. Defaults to
scrolling 50% of the view width.
Bug fixes:
- Status view: show error when failing to open a file.
- Status view: report failures to update a file.
- Blame view: fix problem with uninitialized variable.
- Blame view: use line number information when loading blame for
specific commit.
- Fix handling of quoted strings in the config file.
- Fix horizontal scrolling glitches.
tig-0.14
--------
Incompatibilities:
- The screen-resize action has been deprecated. It had no real use for
users and was never meant to be exposed.
- The "tree-parent" action was renamed to "parent". Warnings will be
emitted for transition.
- Remove parsing of deprecated option -S and subcommands log and diff.
- The "author" color replaces "main-author". Setting the latter will
now set the "author" color.
Improvements:
- Horizontal scrolling. Bound to Left/Right by default.
- Read tigrc(5) options from git configuration files using the syntax:
[tig] show-rev-graph = true
[tig "color"] cursor = yellow red bold
[tig "bind"] generic = P parent
- Tree view: avoid flickering when updating.
- Tree view: annotate entries with commit information.
- Tree & blob view: open any blob in an editor.
- Stage & main view: restore view position when reloading.
- Blame view: load blame for parent commit. For merge commits the parent
is queried. Bound to ',' by default via the existing "parent" action.
- Abbreviate author names to initials when the width of the author column
is below 6 characters.
Bug fixes:
- Tree view: fix memory corruption bug when updating.
- Tree view: improve handling of empty trees.
- Status view: fix reverting of unmerged files.
- Fix regression for non-UTF-8 locales corrupting the view data.
- Fix regression parsing multiple spaces in ~/.tigrc.
tig-0.13
--------
Incompatibilities:
- Commands from the environment (e.g. TIG_MAIN_CMD) will no longer have
access to shell features, such as subshells and variable expansion.
The easiest way to upgrade your configuration is to put such commands
in a script file or as a git alias.
Improvements:
- Display repository references in the sorted order: tags, heads,
tracked remotes, remotes.
- Add bash completion for blame.
- Tree view: edit files of the current branch.
- Run requests: new identifiers %(directory), %(file), and %(ref)
- Improve responsiveness and view loading speed by using select(2).
Bug fixes:
- Separate blame revision and file argument by "--" to avoid problems.
- Main view: fix redrawing of the last commit wrt. the revision graph.
- Fix waiting for input after executing a run request in pager mode.
- Status & stage view: refuse to open directories and deleted files.
- Tree view: show error when requesting blame for all non-file entries.
- Do not draw loading views, which are not displayed.
- Fix launching of mergetool from a subdirectory.
* Fix issue where subclasses of Template failed to pick up attributes in the
searchlist
* Remove old/outdated bundled memcached python client
* Allow for #encoding directives to exist after a comment (i.e. not the first
line in a module)
* Remove support for WebWare servlets (which caused significant performance
slowdowns on Mac OS X)
* Old/stale code pruned in preparation for Python 3 support
Changes 2.4.1:
* --quiet flag added to `cheetah` to silence printing to stdout
* Refactoring to minimize the amount of forked code for Python3
* Template.compile() will no longer create class names with numerous leading
underscores
* DirectiveAnalyzer (cheetah-analyze script) added to report directive usage in
templates
* Older LaTeX docs converted to rst for Sphinx
* Prevent #raw blocks from evaluating $-placeholders and escaped strings
* New tests added to verify PSP behavior and other untested internals
Changes 2.4.0:
* Fix a major performance regression in Template.__init__()
* More graceful handling of unicode when calling .respond() to render a template
* Minor code updates
* Update the default filter
* Compilation of sha1_file.c on BSD platforms were broken due to our
recent use of getrlimit() without including <sys/resource.h>.
* "git config" did not diagnose incorrect configuration variable names.
* "git format-patch" did not wrap a long subject line that resulted from
rfc2047 encoding.
* "git instaweb" should work better again with plackup.
* "git log --max-count=4 -Sfoobar" now shows 4 commits that changes the
number of occurrences of string "foobar"; it used to scan only for 4
commits and then emitted only matching ones.
* "git log --first-parent --boundary $c^..$c" segfaulted on a merge.
* "git pull" into an empty branch should have behaved as if
fast-forwarding from emptiness to the version being pulled, with
the usual protection against overwriting untracked files.
* "git submodule" that is run while a merge in the superproject is in
conflicted state tried to process each conflicted submodule up to
three times.
* "git status" spent all the effort to notice racily-clean index entries
but didn't update the index file to help later operations go faster in
some cases.
* Added a DO server which allows modification of internal data
structures using a simple interface.
* Tooltips now show the object name and the object type for
informational purposes.
* Opens default document when using NSWindows95InterfaceStyle.
* Correction for some nib loading issues.
* Limited support for standalone views.
* Fixes for various bugs.
* Parallel building supported using e.g. make -j 2
* Support source files in subdirectories without using a subproject.
* Support header files in sub-subdirectories.
* Batch-compile Java files (much faster).
* Fixes for building documentation.
New in 2.10:
* Support for Linux/S390.
<sigsegv.h> now defines a macro SIGSEGV_FAULT_ADDRESS_ALIGNMENT.
It is either 1 or pagesize. Its meaning is that
- The fault address passed to a SIGSEGV handler has been rounded down
to a multiple of SIGSEGV_FAULT_ADDRESS_ALIGNMENT.
- The address and length arguments of sigsegv_register function calls
must be multiples of SIGSEGV_FAULT_ADDRESS_ALIGNMENT.
* Faster distinction between stack overflow and other fault on OpenBSD.
* "git apply" used to confuse lines updated by previous hunks as lines
that existed before when applying a hunk, contributing misapplication
of patches with offsets.
* "git branch --track" (and "git checkout --track --branch") used to
allow setting up a random non-branch that does not make sense to follow
as the "upstream". The command correctly diagnoses it as an error.
* "git checkout $other_branch" silently removed untracked symbolic links
in the working tree that are in the way in order to check out paths
under it from the named branch.
* "git cvsimport" did not bail out immediately when the cvs server cannot
be reached, spewing unnecessary error messages that complain about the
server response that it never got.
* "git diff --quiet" did not work very well with the "--diff-filter" option.
* "git grep -n" lacked a long-hand synonym --line-number.
* "git stash apply" reported the result of its operation by running
"git status" from the top-level of the working tree; it should (and
now does) run it from the user's working directory.
* various build-fixes for the rpm/dpkg scripts.
* add "--enable-rpath-link" option to Ada95/configure, to allow
packages to suppress the rpath feature which is normally used for
the in-tree build of sample programs.
* corrected definition of libdir variable in Ada95/src/Makefile.in,
needed for rpm script.
* add "--with-shared" option to Ada95/configure script, to allow
making the C-language parts of the binding use appropriate compiler
options if building a shared library with gnat.
