Martijn Dekker 3613da4240 Remove unused libcoshell ... The coshell(1) command, which is required for libcoshell to be useful, is not known to be shipped by any distribution. It was removed by the ksh-community fork and hence also by 93u+m (in 2940b3f5). The coshell facility as a whole is obsolete and insecure. For a long time now, the statically linked libcoshell library has been 40+ kilobytes of dead weight in the ksh binary. Prior discussion (ksh2020): https://github.com/att/ast/issues/619 src/lib/libcoshell/*: - Removed. src/cmd/ksh93/*: - Remove the SHOPT_COSHELL compiler option (which was enabled) and a lot of code that was conditional upon #ifdef SHOPT_COSHELL. - init.c: e_version[]: Removing SHOPT_COSHELL changed the "J" feature identifier in ${.sh.version} to a lowercase "j", which was conditional upon SHOPT_BGX (background job extensions). But src/cmd/ksh93/RELEASE documents (at 08-12-04, on line 1188): | +SHOPT_BGX enables background job extensions. Noted by "J" in | the version string when enabled. [...] That is the only available documentation. So change that "j" back to a "J", leaving the version string unchanged after this commit. - jobs.c: job_walk(): We need to keep one 'job_waitsafe(SIGCHLD);' call that was conditional upon SHOPT_COSHELL; removing it caused a regression test failure in tests/sigchld.sh, 'SIGCHLD blocked for script at end of pipeline' (which means that until now, a ksh compiled without libcoshell had broken SIGCHLD handling.) bin/package, src/cmd/INIT/package.sh: - Don't export COSHELL variable.		2020-07-17 19:28:52 +01:00
