Log message:
diffutils: update to 3.9.

* Noteworthy changes in release 3.9 (2023-01-15) [stable]

** Bug fixes

  diff -c and -u no longer output incorrect timezones in headers
  on platforms like Solaris where struct tm lacks tm_gmtoff.
  [bug#51228 introduced in 3.4]

Log message:
diffutils: update to 3.8

* Noteworthy changes in release 3.8 (2021-08-01) [stable]

** Incompatible changes

  diff no longer treats a closed stdin as representing an absent file
  in usage like 'diff --new-file - foo <&-'.  This feature was rarely
  if ever used and was not portable to POSIX platforms that reopen
  stdin on exec, such as SELinux if the process underwent an AT_SECURE
  transition, or HP-UX even if not setuid.

** Bug fixes

  diff and related programs no longer get confused if stdin, stdout,
  or stderr are closed.  Previously, they sometimes opened files into
  file descriptors 0, 1, or 2 and then mistakenly did I/O with them
  that was intended for stdin, stdout, or stderr.

  cmp, diff and sdiff no longer treat negative command-line
  option-arguments as if they were large positive numbers.

archivers: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and
SHA512 hashes

Could not be committed due to merge conflict:

The following distfiles were unfetchable (note: some may be only fetched
conditionally):

./devel/pvs/distinfo pvs-3.2-solaris.tgz
./devel/eclipse/distinfo eclipse-sourceBuild-srcIncluded-3.0.1.zip

Log message:
devel: Remove SHA1 hashes for distfiles

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:
release 3.6:

** New features

  When one file is a prefix of the other, cmp now appends the shorter
  file's size to the EOF diagnostic.

** Bug fixes

  Using an invalid regular expression with --ignore-matching-lines=RE (-I)
  no longer causes stack overflow.  Before, with an invocation like the
  following, diff would diagnose the error, but would still proceed to
  blow the stack: diff -Ia -I\\ <(echo) <(echo b)
  [bug introduced in 2.9]

  diff no longer mishandles line numbers exceeding 2**31 on Mingw-w64.

  the ---presume-output-tty (ostensibly test-only) option would cause
  diff --color to read an uninitialized variable
  [bug introduced in 3.4]

** Performance changes

  diff's default algorithm has been tweaked to deal better with larger
  files, reversing some of the changes made in diffutils-3.4.

Log message:
Updated devel/diffutils to 3.5
------------------------------
* Noteworthy changes in release 3.5 (2016-08-20) [stable]
** Bug fixes
  diff3 no longer malfunctions due to use-after-free
  [bug introduced in 3.4]

  diff --color no longer colorizes when TERM=dumb

Log message:
Updated devel/diffutils to 3.4
------------------------------
* Noteworthy changes in release 3.4 (2016-08-08) [stable]

** New features

   diff accepts two new options --color and --palette to generate
   and configure colored output.  --color takes an optional argument
   specifying when to colorize a line: --color=always, --color=auto,
   --color=never.  --palette is used to configure which colors are used.

** Bug fixes

  When binary files differ, diff now exits with status 1 as POSIX requires.
  Formerly it exited with status 2.

  Unless the --ignore-file-name-case option is used, diff now
  considers file names to be equal only if they are byte-for-byte
  equivalent.  This fixes a bug where diff in an English locale might
  consider two Asian file names to be the same merely because they
  contain no English characters.

  diff -B no longer generates incorrect output if the two inputs
  each end with a one-byte incomplete line.

  diff --brief no longer reports a difference for unusual identical files.
  For example, when comparing a file like /proc/cmdline (for which the linux
  kernel reports st_size of 0 even though it is not an empty file) to a
  copy of that file's contents residing on a "normal" file system:
    $ f=/proc/cmdline; cp $f k; diff --brief $f k
    Files /proc/cmdline and k differ

** Performance changes

  diff's default algorithm has been adjusted to output higher-quality
  results at somewhat greater computational cost, as CPUs have gotten
  faster since the algorithm was last tweaked in diffutils-2.6 (1993).
