I would prefer not to make a build-time option of this, because then the
documentation has say something in line with whether files are compressed by
default depends on how ccache was built, which I think would be unfortunate. I
chose to not include the --{en,dis}able-zlib option from the original patch for
the same reason. I think it's better to strive for good defaults and few
build-time options.

i didnt mean the configure option was in place of the runtime knobs
regardless, unless the compression is very low overhead, the default
should be off

If there are no major problems with the feature in that first release then make it a default in the next release after that (e.g. ccache-3.1). The compression feature is actually quite well-tested: it has been enabled by default in Debian's ccache packages since 2007. But I'm leaning on disabling compression by default for ccache anyway. Score so far: 4 votes (2 off-list) for default to off and 0 votes for default to on. My direct mode feature, on the other hand, is a much larger and less tested change, which I'm very well aware of. My secret plan was to try to get people to test my first announced release, and now the 3.0pre0 release, but neither release has triggered much reaction. So, maybe 3.0 will have to have direct mode disabled by default, unless I find a way to get more testers. :-) (Opinions are welcome, as usual.) -- Joel ___ ccache mailing list ccache@lists.samba.org https://lists.samba.org/mailman/listinfo/ccache

All defaults, CCACHE_PREFIX=distcc. I have nothing out of the ordinary to report. Thanks for your work!
