gotwebd.conf: unbreak max_repos_display 0 in 1a0c81fb61 I've added a range check too strict for max_repos_display, as zero is allowed and means "show all the repositories".

gotwebd: set chroot path in config_init() saves a bit fiddling around with ternary operators. sockets_run() will reset the chroot to the default since it calls again config_init(), but at that stage it's not important anymore. ok stsp@

gotwebd.conf: error if chroot is the empty string

gotwebd.conf: range-check numeric values and raise errors

gotwebd.conf: disallow yes/no for booleans Supporting both "no" and "on" as valid syntax with an opposite meaning could easily result in accidental misconfiguration. Suggested by stsp, tracey agrees. Patch by Josiah Frentsos, thanks!

gotwebd: disallow 1 for max_commits_display and report range errors ok stsp

PF_UNSPEC -> AF_UNSPEC While they're the same value, it's more correct to use AF_UNSPEC in this case. While here, change SOCK_DGRAM to SOCK_STREAM since it's what we'll be using. ok stsp@

remove host, host_v4 and host_v6; rename host_dns -> host host_dns() (now just host()) uses getaddrinfo() which knows already how to handle IPv4/IPv6 addresses. Saves a good amount of duplication. ok stsp@

gotwebd: drop unused `prefixlen' from struct address ok stsp@

gotwebd: provide gotweb_render_page() entrypoint for all pages simplify gotweb_process_request more, handling all the pages inside the big switch. There's only one entrypoint for rendering the templates gotweb_render_page() that takes the page' content as argument. The only real difference is that gotweb_render_index() now skips directory entries which fails to handle. ok tracey@

gotwebd.conf: use `listen on socket' syntax for UNIX sockets too and drop unix_socket and unix_socket_path in server context. ok stsp@

fmt

add respect_exportok flag, defaulting to off allows to hide repositories if they have the magic git-daemon-export-ok file ok op@ tracey@ stsp@

gotwebd.conf: add syntax for defining macros and document them macros are already supported by parse.y but can only be defined with the -D flag. This adds the ``usual'' syntax for macros: varname = string. While here, fix the markup of the -D flag in the SYNOPSIS and sync the global `grammar' yacc rule with other parse.y grammars in base: - add the /* empty */ comment - increment file->errors on errors ok stsp@, "sure, go for it" tracey@

gotwebd: fix crash handling -D Avoid crashing by corrupting the pointer instead of writing to it and fix how sym is generated: it shouldn't include the '=' sign. ok / improvement tb@
