Several changes are involved since they are all interrelated. These
changes affect about 1000 files.
The first major change is rewriting bsd.builtin.mk as well as all of
the builtin.mk files to follow the new example in bsd.builtin.mk.
The loop to include all of the builtin.mk files needed by the package
is moved from bsd.builtin.mk and into bsd.buildlink3.mk. bsd.builtin.mk
is now included by each of the individual builtin.mk files and provides
some common logic for all of the builtin.mk files. Currently, this
includes the computation for whether the native or pkgsrc version of
the package is preferred. This causes USE_BUILTIN.* to be correctly
set when one builtin.mk file includes another.
The second major change is teach the builtin.mk files to consider
files under ${LOCALBASE} to be from pkgsrc-controlled packages. Most
of the builtin.mk files test for the presence of built-in software by
checking for the existence of certain files, e.g. <pthread.h>, and we
now assume that if that file is under ${LOCALBASE}, then it must be
from pkgsrc. This modification is a nod toward LOCALBASE=/usr. The
exceptions to this new check are the X11 distribution packages, which
are handled specially as noted below.
The third major change is providing builtin.mk and version.mk files
for each of the X11 distribution packages in pkgsrc. The builtin.mk
file can detect whether the native X11 distribution is the same as
the one provided by pkgsrc, and the version.mk file computes the
version of the X11 distribution package, whether it's built-in or not.
The fourth major change is that the buildlink3.mk files for X11 packages
that install parts which are part of X11 distribution packages, e.g.
Xpm, Xcursor, etc., now use imake to query the X11 distribution for
whether the software is already provided by the X11 distribution.
This is more accurate than grepping for a symbol name in the imake
config files. Using imake required sprinkling various builtin-imake.mk
helper files into pkgsrc directories. These files are used as input
to imake since imake can't use stdin for that purpose.
The fifth major change is in how packages note that they use X11.
Instead of setting USE_X11, package Makefiles should now include
x11.buildlink3.mk instead. This causes the X11 package buildlink3
and builtin logic to be executed at the correct place for buildlink3.mk
and builtin.mk files that previously set USE_X11, and fixes packages
that relied on buildlink3.mk files to implicitly note that X11 is
needed. Package buildlink3.mk should also include x11.buildlink3.mk
when linking against the package libraries requires also linking
against the X11 libraries. Where it was obvious, redundant inclusions
of x11.buildlink3.mk have been removed.
Changes since version 8.12.10:
Use QueueFileMode when opening qf files. This error was a
regression in 8.12.10. Problem detected and diagnosed
Lech Szychowski of the Polish Power Grid Company.
Properly count the number of queue runners in a work group and
make sure the total limit of MaxQueueChildren is not
exceeded. Based on patch from Takayuki Yoshizawa of
Techfirm, Inc.
Take care of systems that can generate time values where the
seconds can exceed the usual range of 0 to 59.
Problem noted by Randy Diffenderfer of EDS.
Avoid regeneration of identical queue identifiers by processes
whose process id is the same as that of the initial
sendmail process that was used to start the daemon.
Problem noted by Randy Diffenderfer of EDS.
When a milter invokes smfi_delrcpt() compare the supplied
recipient address also against the printable addresses
of the current list to deal with rewritten addresses.
Based on patch from Sean Hanson of The Asylum.
BadRcptThrottle now also works for addresses which return the
error mailer, e.g., virtusertable entries with the
right hand side error:. Patch from Per Hedeland.
Fix printing of 8 bit characters as octals in log messages.
Based on patch by Andrey J. Melnikoff.
Undo change of algorithm for MIME 7-bit base64 encoding to 8-bit
text that has been introduced in 8.12.3. There are some
examples where the new code fails, but the old code works.
To get the 8.12.3-8.12.10 version, compile sendmail with
-DMIME7TO8_OLD=0. If you have an example of improper
7 to 8 bit conversion please send it to us.
Return normal error code for unknown SMTP commands instead of
the one specified by check_relay or a milter for a
connection. Problem noted by Andrzej Filip.
Some ident responses contain data after the terminating CRLF which
causes sendmail to log "POSSIBLE ATTACK...newline in string".
To avoid this everything after LF is ignored.
If the operating system supports O_EXLOCK and HASFLOCK is set
then a possible race condition for creating qf files
can be avoided. Note: the race condition does not
exist within sendmail, but between sendmail and an
external application that accesses qf files.
Log the proper options name for TLS related mising files for
the CACertPath, CACertFile, and DHParameters options.
Do not split an envelope if it will be discarded, otherwise df
files could be left behind. Problem found by Wolfgang
Breyha.
The use of the environment variables HOME and HOSTALIASES has been
deprecated and will be removed in version 8.13. This only
effects configuration which preserve those variable via the
'E' command in the cf file as sendmail clears out its entire
environment.
Portability:
Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther).
Solaris 10 has unsetenv(), patch from Craig Mohrman of
Sun Microsystems.
LIBMILTER: Add extra checks in case a broken MTA sends bogus data
to libmilter. Based on code review by Rob Grzywinski.
SMRSH: Properly assemble commands that contain '&&' or '||'.
Problem noted by Eric Lee of Talking Heads.
New Files:
devtools/OS/Darwin.7.0
as PREFER_PKGSRC. Preferences are determined by the most specific
instance of the package in either PREFER_PKGSRC or PREFER_NATIVE. If
a package is specified in neither or in both variables, then PREFER_PKGSRC
has precedence over PREFER_NATIVE.
BUILDLINK_PREFER_PKGSRC
This variable determines whether or not to prefer the pkgsrc
versions of software that is also present in the base system.
This variable is multi-state:
defined, or "yes" always prefer the pkgsrc versions
not defined, or "no" only use the pkgsrc versions if
needed by dependency requirements
This can also take a list of packages for which to prefer the
pkgsrc-installed software. The package names may be found by
consulting the value added to BUILDLINK_PACKAGES in the
buildlink[23].mk files for that package.
The sendmail Mail Filter API (Milter) is designed to allow third-party
programs access to mail messages as they are being processed in order to
filter meta-information and content.
libmilter provides the implementation of this API.
