python - gevent-socketio not using my @app.route endpoint for socketio -

-

i using flask gevent-socketio:

$ cat requirements.txt  flask==0.10.1 jinja2==2.7.1 markupsafe==0.18 werkzeug==0.9.3 argparse==1.2.1 gevent==0.13.8 gevent-socketio==0.3.5-rc2 gevent-websocket==0.3.6 greenlet==0.4.1 itsdangerous==0.23 wsgiref==0.1.2

i'm using pretty standard setup start server:

#called __main__ def run_dev_server():     app.debug = true     port = 5000     dapp = werkzeug.debug.debuggedapplication(app, evalex = true)     socketioserver(('', port), dapp, resource="socket.io").serve_forever()

and pretty standard hook socketio namespace:

@app.route('/socket.io/<path:rest>') def push_stream(rest):     print 'ws connect', rest     try:         socketio.socketio_manage(request.environ, {'/join_notification': joinsnamespace}, request)     except exception e:         app.logger.error("exception while handling socketio connection", exc_info=true)     return flask.response()

however, i'm having problems 'connect' events aren't being fired on client. after little digging, realized though getting 127.0.0.1 - - [2013-08-19 12:53:57] "get /socket.io/1/websocket/170191232666 http/1.1" 101 - - messages in output, wasn't getting ws connect message (while other print statements in code working fine). commented out endpoint, , sure enough it's not being called. explain why namespace isn't being used. why? registering namespace wrong?

print app.url_map yields:

map([<rule '/' (head, options, get) -> root>,  <rule '/socket.io/<rest>' (head, options, get) -> push_stream>,  <rule '/static/<filename>' (head, options, get) -> static>])

so nothing out of ordinary.

edit: client code:

socket = io.connect('/join_notification') console.log(socket)  socket.on('connect', function() {     console.log('connected websocket')     socket.emit('login', {'name': data['name']}) })  socket.on('disconnect', function() {     console.log('d/c\'d websocket') })  socket.on('join_error', function() {     ... })  socket.on('join_success', function(data){     ... })  socket.on('join', function(data) {     ... })

the weird behavior because of line:

dapp = werkzeug.debug.debuggedapplication(app, evalex = true)

socketio , werkzeug debugger don't work together. there open issue see: https://github.com/abourget/gevent-socketio/issues/114

but can work around making custom debugger class.

from werkzeug.debug import debuggedapplication class mydebuggedapplication(debuggedapplication):     def __call__(self, environ, start_response):         # check if websocket call         if "wsgi.websocket" in environ , not environ["wsgi.websocket"] none:             # websocket call, no debugger ;)             return self.app(environ, start_response)         # else go on debugger         return debuggedapplication.__call__(self, environ, start_response)  # remember call overwritten debugger in run_dev_server() function dapp = mydebuggedapplication(app, evalex = true)

the patch relies on environment-key wsgi.websocket, seems present in websocket calls. careful, haven't put thought that, there might other issues.

visual studio - TFS will not accept changes I've made to a Java project -

-
i using tfs's team explorer manage visual studio projects. recently, i've created new java project (not in visual studio) manually added tfs using source control control explorer in visual studio. after added java project tfs, made changes , bug fixes. then, went visual studio , opened source control explorer check in changes, tfs thinks no changes made. it seems needed check out project before making changes. guess erroneously expected tfs track automatically, okay. so, using source control explorer in tfs, checked out project, , tried check in pending changes. when tried check in, got following message: all of changes either unmodified files or locks. changes have been undone server. is there way convince server indeed project has changed? how can check in changes have made? thank help.
