I cannot set the following in login.conf > :setenv=MAIL=/var/mail/$,BLOCKSIZE=K,\ > HTTP_PROXY=http\c//194.145.60.1\c9400,\ > HTTPS_PROXY=http\c//194.145.60.1\c9400,\ > FTP_PROXY=ftp\c//194.145.60.1\c9400,\ > NO_PROXY="localhost,.siemens.net,.siemens.com,.siemens.de":\ because comma seperates the vars themselves. While fetch(1) and curl(1) also supports whitespace-delimited values, poudriere chokes on: https://github.com/freebsd/poudriere/issues/669 There must be some mechanism to escape commas just like semicolons.
Poudriere is effectively fine here with this syntax (no quotes needed): :setenv=MAIL=/var/mail/$,BLOCKSIZE=K,NO_PROXY=localhost .siemens.net .siemens.com .siemens.de:\
I cannot confirm this. Besides poudriere, it whould be possible in general to have commas in env values.
I think I have traced down the cause: cap_mkdb uses cgetnext() whose manpage says: > String capability values may contain any character. Non-printable ASCII > codes, new lines, and colons may be conveniently represented by the use > of escape sequences: > > ^X ('X' & 037) control-X > \b, \B (ASCII 010) backspace > \t, \T (ASCII 011) tab > \n, \N (ASCII 012) line feed (newline) > \f, \F (ASCII 014) form feed > \r, \R (ASCII 015) carriage return > \e, \E (ASCII 027) escape > \c, \C (:) colon > \\ (\) back slash > \^ (^) caret > \nnn (ASCII octal nnn) While I have tried to do \054, it is still not working because the setenv magic is performed with login_getcaplist() in > ./lib/libutil/login_class.c: const char **set_env = login_getcaplist(lc, "setenv", ","); So also the \054 is converted to comma, the subsequent call adds its own sematics to split the setenv capability with comma. So it would require something like \O which is used in login_class only and if ((np = substvar(p, pwd, hlen, pch, nlen)) != NULL) { setenv(*set_env, np, 1); free(np); } and np needs to be processed for \O to replace with a comma. If I understand ./lib/libc/gen/getcap.c correctly the blackslash is retained by "*mp++ = *(bp-1)" if the escape char is unknown.
Ok, on HEAD, I've got a change that, for that login.conf entry, gives me: 0: MAIL=/var/mail/$ 1: BLOCKSIZE=K 2: HTTP_PROXY=http://194.145.60.1:9400 3: HTTPS_PROXY=http://194.145.60.1:9400 4: FTP_PROXY=ftp://194.145.60.1:9400 5: NO_PROXY=localhost,.siemens.net,.siemens.com,.siemens.de as the output. Specifically, it treats a quoted string as a quoted string, and then removes the quotes. I'll create a review for it.
I created review D25368
Sean, thanks for the patch. I will try that next week and let you know!

It needs a manpage update to tell that quotes will help for commas or maybe other characters affecting parsing.
