Hi!
I have problem with using git-remote-fd function. I create two local
pipes for communication for locally running process git pull. Then I
start git-upload-pack on remote side (this process is started in
different part of my code and it works correctly). Communication runs
successfully and when remote side finish, I want to close local pipes
to finish local process. I call close function to all of these pipes,
but unfortunatelly local process doesnt finish (in this moment
transfered data aresaved in /.git/object/pack folder in .pack files)
and hanging on. But if I kill child of this local process, downloaded
files are unpacked and files are created sucessfully. I think this way
is not so correct. Can someone help me and tell me what am I doing
wrong? Thank You. Code is in an attachement (its part of big system).
#create local pipes for cimmunication
local_r, local_w = os.pipe()
remote_r, remote_w = os.pipe()
#start local git process
client_process = subprocess.Popen("/usr/bin/git pull fd::{0},{1}".format(remote_r, local_w,), shell=True)
#start git process on remote side
remoteGit = proc.runDaemon("sudo git-upload-pack /tmp/testGit")
#set
epoll = select.epoll()
epoll.register(local_r, select.EPOLLIN)
#register from remote side
epoll.register(proc.fd, select.EPOLLIN)
while True:
events = epoll.poll(1)
for fd, event in events:
if fd == local_r:
#event on local process
if event & select.EPOLLIN:
rd = os.read(local_r, 5000)
if rd:
#write data to remote side
remoteGit.writeToChannel(rd)
else:
proc.writeError("Local socket write error")
client_process.kill()
return 1
else:
proc.writeError("Local socket error")
client_process.kill()
return 1
else:
if event & select.EPOLLIN:
#get all data from remote side
data = remoteGit.getAll()
remoteGit.stderrWrite()
if not data:
#remote side finished - close local pipes - local process wouldnt finish
os.close(local_r)
os.close(local_w)
os.close(remote_r)
os.close(remote_w)
#get local process pid and kill his child to finish git-remote-fd
gitPid = psutil.Process(client_process.pid).children()[0].pid
os.kill(gitPid, signal.SIGTERM)
return 0
want = len(data)
writed = 0
offset = 0
while(writed != want):
#write data from remote side to local process
wr = os.write(remote_w, data[offset:])
if(wr < 0):
proc.writeError("Local socket write error")
return 1
writed += wr
offset += wr
else:
proc.writeError("Remote socket error")
client_process.kill()
return -1
