Also included are four allocators which also serve as examples
as to how to use the interface. AFAIK, it's sort of like vmem(9)
in userland (not that I know much about vmem, for the manpage
is quite terse, heh).
I imported this not as a dependency, but because I thought it
looked interesting, especially with regard to what's outlined
in the last paragraph. I may use it in porting some linux audio
software at some point, though that's still a ways off ...
A short blurb:
Libarena is a custom memory allocator interface and implementation. Four
allocators are provided: flat LIFO arena allocator, object pool allocator
and two malloc(3) wrappers: one which returns the pointers unadulterated
and one which obeys the requested, arbitrary alignment. These can be used
directly, or through their exported prototype interfaces.
Libarena is meant to provide a baseline interface so allocator's can be
stacked, and to provide a simple and well defined interface for libraries
and applications without becoming mired in features or capabilities. It is
not meant to restrict or confine what custom allocators can actually
accomplish. For instance, the included pool and arena allocators include a
suite of string utilities which aren't available in the generic exportable
interface. Note that these string utilities are built upon a generic
interface (see util.h) which can take the prototypical allocation context,
so they are also available to any 3rd party compatible allocators.
Surprisingly few malloc(3) library "replacements" or plug-in interfaces
support a context pointer argument. They're useless for many or most of
the tasks where the ability to specify an alternate malloc(3) could
actually be useful, e.g. poor man's RAII. For network daemons especially
this feature is useful; all allocations for a particular session can be
freed simply by closing the lowest-level allocator object.
Pkgsrc changes:
- The packages supports installation to DESTDIR.
- No more requirement for coreutils/findutils and patch-ab.
- Switched to predefined REPLACE_SH instead of using subst.mk directly.
- Cosmetic changes for MAKEFLAGS.
- The shell script mk/check/check-portability.sh gets confused by some of
the file names in the test archive: skip them.
- Extracting files from testsuite.tar often fails on Darwin (with HFS?)
so we skip this part.
- Extract test archive with pax, it is available on every pkgsrc system.
- Submitted patch-aa to author of convmv long ago.
Changes since version 1.10:
===========================
1.12
- now work with Perl 5.10 using an eval block
- GPL v2 and v3 now
1.11
- test suite compares sorted results of find to fix false alarms on some systems
- test suite now uses tar instead of cp for copying.
- fix a y/n mixup
- at startup we check if Perl::Encode is not too broken (bugs 37757 and 49830
for now). Recent Perl releases are terribly broken. If this won't improve,
I'll have to rewrite convmv in a language with more stable core functionality
:-|. If you are distributor of convmv, please run make test before packaging
to make sure you don't ship convmv with a broken Perl release.
Based on package from pkgsrc-wip, but updated. I changed
the maintainer because I didn't hear back about my changes.

as they appear to have been incorporated upstream. Additionally, the
following changes apply:
December 2006: t1lib-5.1.1:
---------------------------
- DESTDIR support was missing and has been addded in install-target i
for type1afm.
- A bug fix in Anti-Aliasing subsampling code, which could make t1lib crash
under certain conditions.
- Small number of further fixes, in particular with respect to the build
mechanism.
December 2007: t1lib-5.1.2:
---------------------------
- Small number of fixes reported by users. The fixes pertain to a
vulnerability issue, memory access issues.
- More decent handling if Encoding and / or FontBBox specification are
missing (which is invalid with respect to the specification,
but recoverable).
LibThai is a set of Thai language support routines aimed to ease developers'
tasks to incorporate Thai language support in their applications. It includes
important Thai-specific functions e.g. word breaking, input and output methods
as well as basic.
datrie is an implementation of double-array structure for representing trie, as
proposed by Junichi Aoe.
Trie is a kind of digital search tree, an efficient indexing method with O(1)
time complexity for searching. Comparably as efficient as hashing, trie also
provides flexibility on incremental matching and key spelling manipulation.
This makes it ideal for lexical analyzers, as well as spelling dictionaries.
