the new "modula-3-lib" port. The split allows one to save a lot of
disk space by installing only the shared libraries needed for executing
programs. The full "modula-3" port is needed only if you want to
compile programs as well.
Use new custom distfiles which are MUCH smaller than the ones from
DEC.
Use the gcc-2.7.2.1 sources on the system if they are found in
/usr/src/contrib, to avoid having to fetch that distfile.
Use an existing Modula-3 compiler to bootstrap the new one, if
there happens to be one installed on the system. Again, this
eliminates the need to fetch one of the distfiles.
Update the built-in thread-safe malloc to the latest version of
phkmalloc.
Helmet on!
Flameproof vest?
Deployed, Sir!
Heat resistant carbon-fiber cup?
In place!
All defensive systems armed and ready?
Armed and ready, Sir!
Fine, then. Let's get on with it. Reduce shared library version numbers!
Uh, Sir, with all due respect ...
DO YOU HEAR ME??? REDUCE SHARED LIBRARY VERSION NUMBERS!!!
Reducing shared library version numbers! ... <*whirr click*> Done!
All right, soldier, let's get the hell out of here... Soldier? ... Soldier??
First, change the port so that it builds a much smaller subset of
the SRC distribution. This eliminates the enormous swap space
requirements of the earlier port, greatly reduces the footprint of
the installed tree, and cuts the size of the package in half.
Second, include many important new patches. Among them is a slightly
modified version of phkmalloc that is thread-safe for Modula-3.
It eradicates some rare and baffling core dumps that cropped up
from time to time in the previous version of the port. The Modula-3
runtime itself is careful to use mutual exclusion around calls to
malloc. But there remained some sneaky backdoor paths into it from
external libraries.
Confession: In the original version of the Modula-3 port, I used
a major version number of 353 for the shared libraries, to correspond
with the SRC version number 3.5.3. That was a dumb move -- I should
have used 1. The current update is incompatible at the shared
library level, requiring me to increment the major version number
to 354, even though this is still based on SRC release 3.5.3. This
is bound to confuse some folks, unfortunately. I weighed a number
of alternatives, such as (a) cheating and going back to 1, and (b)
using a 4-digit major version such as 3531. But in the end I
decided that 354 would be the best solution, even though it's
confusing.
