We have now fixed that by checking for this exact case in the GPGSSH prereq and I will improve that check further in a future patch. However we are now in a situation where a broken openssh in the future will result in successfull tests but not a working git build afterwards (either not compiling in the expected feature or like in the ssh case runtime failures) resulting in a false sense of security in the tests. This patches try to improve this situation by showing which prereqs failed in the test summary and by adding an environment variable to enforce certain prereqs to succeed or abort the test otherwise.

It not easy right now to get an overview of which ones are missing. When switching to a new machine or environment some libraries and tools might be missing or maybe a dependency broke completely. In this case the tests would indicate nothing since all dependant tests are simply skipped. This could hide broken behaviour or missing features in the build.

I think I misremembered. b3b753b1 (Fit to Plan 9's ANSI/POSIX compatibility layer, 2020-09-10) does talk about a system whose "tr" does not fully emulate POSIX and wants an octal, but that is not a platform we target for to begin with. $ git grep '^[ ]*tr .*\\012['\''"]' $ git grep '^[ ]*tr .*\\n['\''"]' show the same number of hits, even back in v2.0.0. You have to go back to v1.6.0 (which I consider is the oldest and still usable release of significance) to see the source tree without any hit for the latter. The first introduction of tr "\n" (which I consider is a mistake---if we write octal, we do not have to worry about anybody not supporting it) seems to be dea4562b (rerere forget path: forget recorded resolution, 2009-12-25) made by me X-<. ^ permalink raw reply [flat|nested] 11+ messages in thread

It removed most of >the same sort of tr|grep|sort etc. chain in generate-cmdlist.sh. I've looked at the generate-command-list code and TBH i still think this is a better solution. If I read your change correctly you've removed the sort and unique completely since it was not necessary for the use-case. In this case i think it is. Since we call tr with `-s` the grep -v might not be strictly necessary though. Also in this case these commands are only called once at the end of the test run and not in any kind of loop like in the cmdlist code so i think this variant is much easier to read and debug with a negligible performance impact. I tried writing a sh only variant and this is what i came up with. Not sure if this could be much more simplified. It looses the sort though. input="PCRE,JGIT2,JGIT2,,PCRE,JGIT2,PCRE,PCRE2,!PCRE,!WINDOWS,GPG,GPGSSH,PCRE,!GPG,GPG,JGIT2" unique= save_IFS=$IFS IFS=, for prereq in $input do case "$prereq" in '') # Skip empty entries ;; *) case ",$unique," in *,$prereq,*) # Skip over duplicates ;; *) if test -z "$unique" then unique="$prereq" else unique="$unique,$prereq" fi ;; esac esac done IFS=$save_IFS echo $unique ^ permalink raw reply [flat|nested] 11+ messages in thread
