handled in cygserver_init().

checks against this to (try and) prevent multiple copies of

tidy up on cygserver shutdown.

particular, allocate client_request objects on the stack rather
than on the heap, and use the client_request::make_request()
method rather than the old cygserver_request() function.

|
|
|
|
|
|
|
* cygserver_transport_pipes.cc: The main change is to make the
|
|
|
|
|
client try harder to connect to the server if it's previously
|
|
|
|
|
connected, and so has good grounds for believing that the server
|
|
|
|
|
is running.
|
|
|
|
|
(MAX_WAIT_NAMED_PIPE_RETRY): Change to be an enumerator.

|

|
|
|
|
|
(transport_layer_pipes::connect): Add local static variable
|
|
|
|
|
`assume_cygserver'. Set it if a connection is made to cygserver,
|
|
|
|
|
clear it if a connection is not made even after retrying. If set,
|
|
|
|
|
ignore all errors from CreateFile and retry the connection. Catch
|
|
|
|
|
the situation where WaitNamedPipe fails to wait [sic] and add a
|
|
|
|
|
`Sleep (0)' so that the server gets a chance to run.

ignore all errors from CreateFile and retry the connection. Catch
the situation where WaitNamedPipe fails to wait [sic] and add a
`Sleep (0)' so that the server gets a chance to run.

the situation where WaitNamedPipe fails to wait [sic] and add a
`Sleep (0)' so that the server gets a chance to run.
