gotd: return early after disconnect on auth event error This fixes a segv reported by Mikhail. In this path, any error is already logged, client freed, and event_del() called so we don't need to cleanup in done. 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

rename lib/sha1.c to lib/hash.c It will soon grow functions to deal with sha256 too. stsp@ agrees.

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>

fix gotd segfault in libevent while disconnecting clients Sending a DISCONNECT message to the repo process and then killing it and freeing its structure won't work. The message ends up on internal libevent queues and will soon crash because we have freed the memory for the event structre. Sending that message is a leftover from the times when the repo procs were persistent.

fix gotd and gotsh usage() function declaration "function declaration isn't a prototype" should fix the error seen by tracey@ on sparc64

make gotd parent dispatch handlers more robust during teardown We have observed gotd exiting after "cannot find client for fd N" errors. If this occurs then we are likely in the process of disconnecting a client session while processing an event from a child process. Treat the above error as non-fatal and stop processing more events from the child process.

remove \n from log message

make gotd store own PID after daemon(3), and avoid calling daemon(3) needlessly ok op, jamsek

gotd: disconnect on client EOF too Otherwise gotd keeps the (client-closed) sockets around and may prevent new connections from being established since they still count for the limits. ok jamsek, stsp

document the gotd -n option

gotd: move socket path check to parse.y and error from the main process It's handy to have a "bad unix socket path" error being reported directly from the main process since can get caught by `gotd -n'. ok jamsek stsp

gotd: move nrepos check to parse_config ok jamsek stsp
