1 The Future Of Paste 2 =================== 3 4 Introduction 5 ------------ 6 7 Paste has been under development for a while, and has lots of code in it. Too much code! The code is largely decoupled except for some core functions shared by many parts of the code. Those core functions are largely replaced in `WebOb <http://pythonpaste.org/webob/>`_, and replaced with better implementations. 8 9 The future of these pieces is to split them into independent packages, and refactor the internal Paste dependencies to rely instead on WebOb. 10 11 Already Extracted 12 ----------------- 13 14 paste.fixture: 15 WebTest 16 ScriptTest 17 18 paste.lint: 19 wsgiref.validate 20 21 paste.exceptions and paste.evalexception: 22 WebError 23 24 paste.util.template: 25 Tempita 26 27 28 To Be Separated 29 --------------- 30 31 paste.httpserver and paste.debug.watchthreads: 32 Not sure what to call this. 33 34 paste.cascade and paste.errordocuments: 35 Not sure; Ben has an implementation of errordocuments in ``pylons.middleware.StatusCodeRedirect`` 36 37 paste.urlmap, paste.deploy.config.PrefixMiddleware: 38 In... some routing thing? Together with the previous package? 39 40 paste.proxy: 41 WSGIProxy (needs lots of cleanup though) 42 43 paste.fileapp, paste.urlparser.StaticURLParser, paste.urlparser.PkgResourcesParser: 44 In some new file-serving package. 45 46 paste.cgiapp, wphp.fcgi_app: 47 Some proxyish app... maybe WSGIProxy? 48 49 paste.translogger, paste.debug.prints, paste.util.threadedprint, wsgifilter.proxyapp.DebugHeaders: 50 Some... other place. Something loggy. 51 52 paste.registry, paste.config: 53 Not sure. Alberto Valverde expressed interest in splitting out paste.registry. 54 55 paste.cgitb_catcher: 56 Move to WebError? Not sure if it matters. For some reason people use this, though. 57 58 59 To Deprecate 60 ------------ 61 62 (In that, I won't extract these anywhere; I'm not going to do any big deletes anytime soon, though) 63 64 paste.recursive 65 Better to do it manually (with webob.Request.get_response) 66 67 paste.wsgiwrappers, paste.request, paste.response, paste.wsgilib, paste.httpheaders, paste.httpexceptions: 68 All the functionality is already in WebOb. 69 70 paste.urlparser.URLParser: 71 Really this is tied to paste.webkit more than anything. 72 73 paste.auth.*: 74 Well, these all need to be refactored, and replacements exist in AuthKit and repoze.who. Some pieces might still have utility. 75 76 paste.debug.profile: 77 I think repoze.profile supersedes this. 78 79 paste.debug.wdg_validator: 80 It could get reimplemented with more options for validators, but I'm not really that interested at the moment. The code is nothing fancy. 81 82 paste.transaction: 83 More general in repoze.tm 84 85 paste.url: 86 No one uses this 87 88 89 Undecided 90 --------- 91 92 paste.debug.fsdiff: 93 Maybe ScriptTest? 94 95 paste.session: 96 It's an okay naive session system. But maybe Beaker makes it irrelevant (Beaker does seem slightly more complex to setup). But then, this can just live here indefinitely. 97 98 paste.gzipper: 99 I'm a little uncomfortable with this in concept. It's largely in WebOb right now, but not as middleware. 100 101 paste.reloader: 102 Maybe this should be moved to paste.script (i.e., paster serve) 103 104 paste.debug.debugapp, paste.script.testapp: 105 Alongside other debugging tools, I guess 106 107 paste.progress: 108 Not sure this works. 109
