make gitwrapper ignore 'permission denied' for repository paths We recommend that gotsh users should not have direct filesystem access to repositories served by gotd. Which means admins will be setting things up as follows if public read-access should be denied: chown _gotd /git chmod 700 /git su -m _gotd -c 'gotadmin init /git/repo.git" However, gitwrapper would error out when repositories listed in gotd.conf were inaccessible to the user invoking gitwrapper: git-upload-pack: /etc/gotd.conf:2: realpath /git/repo.git: Permission denied Make gitwrapper ignore such errors as they are expected in this situation. While here, add a PROC_GITWRAPPER process ID for use as a global variable parse.y can check while special-casing any specific behaviour required by gitwrapper. (The worse alternative would have been adding a new global variable to parse.y just to control the behaviour on realpath errors.) ok op@

drop unused strlen; ok stsp@

remove dependency of gitwrapper on gotd/auth.c Move gotd_auth_parseuid() from auth.c to parse.y as gotd_parseuid(), and remove auth.c from the list of source files required by gitwrapper.

remove dependency of gitwrapper on gotd/listen.c Move gotd_find_uid_connection_limit() from listen.c into parse.y and remove listen.c from the list of source files required by gitwrapper.

make gotd/gitwrapper start up even if a repository is missing on disk This should result in more useful behaviour when gitwrapper runs and repositories listed in gotd.conf do not yet exist or do no longer exist.

grammar fix for parse.y error message

reject overlapping protected branch vs. tag namespaces ok op@

gotd.conf: free STRINGS in all code paths ok stsp@

gotd.conf: fix memleak in `protect' error path and disallow dups too ok stsp@

add support for protecting references against 'got send -f' to gotd ok op@

avoid gitwrapper printing a warning when /etc/gotd.conf does not exist gotd still requires the config file, of course, but gitwrapper must treat is as optional and remain silent if the file cannot be found.

add gitwrapper(1) ok op@, tracey@ earlier version

gotd requires a config file; don't fail silently when gotd.conf cannot be read Fixes an issue encountered by mlarkin@ where the auth process was working with an empty list of repositories and kept saying it could not find a repository which was obviously listed in gotd.conf. Now we can see errors from fopen() in the logs instead. Old code was copied from gotwebd where the config file is optional.

include sha2.h too where sha1.h is included In preparation for wide sha256 support; stsp@ agrees. Change done mechanically with find . -iname \*.[cy] -exec sam {} + X ,x/<sha1\.h>/i/\n#include <sha2.h>

rm unused boolean grammar. ok stsp@
