./databases/libdbh2, Library to create disk based Hashtables

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 5.0.16, Package name: libdbh2-5.0.16, Maintainer: pkgsrc-users

Disk based hashes is a method to create multidimensional binary trees on disk.
This library permits the extension of database concept to a plethora of
electronic data, such as graphic information. With the multidimensional binary
tree it is possible to mathematically prove that access time to any
particular record is minimized (using the concept of critical points from
calculus), which provides the means to construct optimized databases for
particular applications.

(From: doc/html/DBH.html)
Disk Based Hashtables (DBH) 64 bit ? Library to create and manage hash
tables residing on disk. Associations are made between keys and values
so that for a given a key the value can be found and loaded into memory
quickly. Being disk based allows for large and persistent hashes. 64 bit
support allows for hashtables with sizes over 4 Gigabytes on 32 bit
systems. Quantified key generation allows for minimum access time on
balanced multidimensional trees.

Log message:
all: migrate some SourceForge homepage URLs back from https to http
https://mail-index.netbsd.org/pkgsrc-changes/2020/01/18/msg205146.html
In the above commit, the homepage URLs were migrated from http to https,
assuming that SourceForge would use the same host names for both http and
https connections. This assumption was wrong. Their documentation at
https://sourceforge.net/p/forge/documentation/Custom%20VHOSTs/ states
that the https URLs use the domain sourceforge.io instead.
To make the homepages from the above commit reachable again, pkglint has
been extended to check for reachable homepages. This check is only
enabled when the --network command line option is given.
Each of the homepages that referred to https://$project.sourceforge.net
before was migrated to https://$project.sourceforge.io (27), and if that
was not reachable, to the fallback URL https://$project.sourceforge.net
(163).

Log message:
all: migrate several HOMEPAGEs to https
pkglint --only "https instead of http" -r -F
With manual adjustments afterwards since pkglint 19.4.4 fixed a few
indentations in unrelated lines.
This mainly affects projects hosted at SourceForce, as well as
freedesktop.org, CTAN and GNU.

Log message:
Fix indentation in buildlink3.mk files.
The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.
There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.
