Hi,
I found some problems with the channel feature. (v7.4.1246)
1. On Win32 GUI, vim hangs up.
:let handle = ch_open('localhost:8765', 'json')
:echo ch_sendexpr(handle, 'hello!')
Vim hangs up.
Or,
:let handle = ch_open('localhost:8765', 'json')
:quit
Vim hangs up.
The following patch seems to fix this:
--- a/src/vim.h
+++ b/src/vim.h
@@ -549,7 +549,7 @@ typedef unsigned long u8char_T; /* l
# ifdef HAVE_SYS_POLL_H
# include <sys/poll.h>
# define HAVE_POLL
-# elif defined(WIN32) && !defined(FEAT_GUI_W32)
+# elif defined(WIN32)
# define HAVE_SELECT
# else
# ifdef HAVE_POLL_H
I'm not sure this is enough.
Maybe returning an error code in channel_read() is better?
2. On Win32 GUI, socket is closed unexpectedly.
After the above patch is applied:
:let handle = ch_open('localhost:8765', 'json')
:echo ch_sendexpr(handle, 'hello!')
The socket is automatically closed.
But this doesn't close the socket:
:call ch_sendexpr(handle, 'hello!', "MyHandler")
This doesn't occur on Win32 CUI.
3. Crashes when opening the same socket twice.
:let handle = ch_open('localhost:8765', 'json')
:let handle = ch_open('localhost:8765', 'json')
Vim crashes.
This also occurs on Linux.
Regards,
Ken Takata
