- 5.9.2 | 2013-11-28
- bugfixes
- avoid possibly failing command in backticks
Some versions of Solaris /bin/sh would cause the extract-help
build script to exit failurefully when the grep command in the
backticks failed (in the presence of "set -e"). Sigh.
- handle low-memory situations like RCS 5.7 (mostly)
For reading comma-v files, RCS 5.7 tries mmap(2), in-core
snarfing, and stdio access, falling back to slower methods
on failure of the faster method. RCS 5.8 maintained the order,
but did not fall back; on failure, it gave up immediately.
This change was originally viewed as a feature, but lately it
seemed more like a bug.
Now, RCS 5.7 behavior is for the most part restored. The
exception is when env var ‘RCS_MEM_LIMIT’ is set; in that case,
failure of a fast method does not fall back to the slower one.
- default for env var ‘RCS_MEM_LIMIT’ relaxed
This used to be 256 kilobytes, a reasonable value a long time
ago, but ridiculously low nowadays. Now, it is "unlimited",
which is more in line w/ the GNU philosophy, anyway:
(info "(standards) Semantics")
Since the env var is mostly intended for testing RCS, you can
normally leave it unset. (Probably it will be removed in a
future release.)
