  290. * Improved websocket draft 76 compliance, thanks to Nick V.
  291. * Rare greenthread.kill() bug fixed, which was probably brought about by a bugfix in greenlet 0.3.
  292. * Easy_installing eventlet should no longer print an ImportError about greenlet
  293. * Support for serving up SSL websockets, thanks to chwagssd for reporting #62
  294. * eventlet.wsgi properly sets 'wsgi.url_scheme' environment variable to 'https', and 'HTTPS' to 'on' if serving over ssl
  295. * Blocking detector uses setitimer on 2.6 or later, allowing for sub-second block detection, thanks to rtyler.
  296. * Blocking detector is documented now, too
  297. * socket.create_connection properly uses dnspython for nonblocking dns. Thanks to rtyler.
  298. * Removed EVENTLET_TPOOL_DNS, nobody liked that. But if you were using it, install dnspython instead. Thanks to pigmej and gholt.
  299. * Removed _main_wrapper from greenthread, thanks to Ambroff adding keyword arguments to switch() in 0.3!
  300. 0.9.12
  301. ======
  302. * Eventlet no longer uses the Twisted hub if Twisted is imported -- you must call eventlet.hubs.use_hub('twistedr') if you want to use it. This prevents strange race conditions for those who want to use both Twisted and Eventlet separately.
  303. * Removed circular import in twistedr.py
  304. * Added websocket multi-user chat example
  305. * Not using exec() in green modules anymore.
  306. * eventlet.green.socket now contains all attributes of the stdlib socket module, even those that were left out by bugs.
  307. * Eventlet.wsgi doesn't call print anymore, instead uses the logfiles for everything (it used to print exceptions in one place).
  308. * Eventlet.wsgi properly closes the connection when an error is raised
  309. * Better documentation on eventlet.event.Event.send_exception
  310. * Adding websocket.html to tarball so that you can run the examples without checking out the source
  311. 0.9.10
  312. ======
  313. * Greendns: if dnspython is installed, Eventlet will automatically use it to provide non-blocking DNS queries. Set the environment variable 'EVENTLET_NO_GREENDNS' if you don't want greendns but have dnspython installed.
  314. * Full test suite passes on Python 2.7.
  315. * Tests no longer depend on simplejson for >2.6.
  316. * Potential-bug fixes in patcher (thanks to Schmir, and thanks to Hudson)
  317. * Websockets work with query strings (thanks to mcarter)
  318. * WSGI posthooks that get called after the request completed (thanks to gholt, nice docs, too)
  319. * Blocking detector merged -- use it to detect places where your code is not yielding to the hub for > 1 second.
  320. * tpool.Proxy can wrap callables
  321. * Tweaked Timeout class to do something sensible when True is passed to the constructor
  322. 0.9.9
  323. =====
  324. * A fix for monkeypatching on systems with psycopg version 2.0.14.
  325. * Improved support for chunked transfers in wsgi, plus a bunch of tests from schmir (ported from gevent by redbo)
  326. * A fix for the twisted hub from Favo Yang
  327. 0.9.8
  328. =====
  329. * Support for psycopg2's asynchronous mode, from Daniele Varrazzo
  330. * websocket module is now part of core Eventlet with 100% unit test coverage thanks to Ben Ford. See its documentation at http://eventlet.net/doc/modules/websocket.html
  331. * Added wrap_ssl convenience method, meaning that we truly no longer need api or util modules.
  332. * Multiple-reader detection code protects against the common mistake of having multiple greenthreads read from the same socket at the same time, which can be overridden if you know what you're doing.
  333. * Cleaner monkey_patch API: the "all" keyword is no longer necessary.
  334. * Pool objects have a more convenient constructor -- no more need to subclass
  335. * amajorek's reimplementation of GreenPipe
  336. * Many bug fixes, major and minor.
  337. 0.9.7
  338. =====
  339. * GreenPipe is now a context manager (thanks, quad)
  340. * tpool.Proxy supports iterators properly
  341. * bug fixes in eventlet.green.os (thanks, Benoit)
  342. * much code cleanup from Tavis

  344. * multitudinous improvements in Py3k compatibility from amajorek
  345. 0.9.6
  346. =====

  348. * improved GreenSocket and GreenPipe compatibility with stdlib
  349. * bugfixes on GreenSocket and GreenPipe objects
  350. * code coverage increased across the board
  351. * Queue resizing
  352. * internal DeprecationWarnings largely eliminated
  353. * tpool is now reentrant (i.e., can call tpool.execute(tpool.execute(foo)))
  354. * more reliable access to unpatched modules reduces some race conditions when monkeypatching
  355. * completely threading-compatible corolocal implementation, plus tests and enthusiastic adoption
  356. * tests stomp on each others' toes less
  357. * performance improvements in timers, hubs, greenpool
  358. * Greenlet-aware profile module courtesy of CCP
  359. * support for select26 module's epoll
  360. * better PEP-8 compliance and import cleanup
  361. * new eventlet.serve convenience function for easy TCP servers
  362. 0.9.5
  363. =====
  364. * support psycopg in db_pool
  365. * smart patcher that does the right patching when importing without needing to understand plumbing of patched module
  366. * patcher.monkey_patch() method replacing util.wrap_*
  367. * monkeypatch threading support
  368. * removed api.named
  369. * imported timeout module from gevent, replace exc_after and with_timeout()
  370. * replace call_after with spawn_after; this is so that users don't see the Timer class
  371. * added cancel() method to GreenThread to support the semantic of "abort if not already in the middle of something"
  372. * eventlet.green.os with patched read() and write(), etc

  378. * deprecate util.py completely
  379. * deprecate saranwrap
  380. * performance improvements in the hubs
  381. * much better documentation overall
  382. * new convenience functions: eventlet.connect and eventlet.listen. Thanks, Sergey!
  383. 0.9.4
  384. =====
  385. * Deprecated coros.Queue and coros.Channel (use queue.Queue instead)
  386. * Added putting and getting methods to queue.Queue.
  387. * Added eventlet.green.Queue which is a greened clone of stdlib Queue, along with stdlib tests.
  388. * Changed __init__.py so that the version number is readable even if greenlet's not installed.
  389. * Bugfixes in wsgi, greenpool
  390. 0.9.3
  391. =====
  392. * Moved primary api module to __init__ from api. It shouldn't be necessary to import eventlet.api anymore; import eventlet should do the same job.
  393. * Proc module deprecated in favor of greenthread
  394. * New module greenthread, with new class GreenThread.
  395. * New GreenPool class that replaces pool.Pool.
  396. * Deprecated proc module (use greenthread module instead)
  397. * tpooled gethostbyname is configurable via environment variable EVENTLET_TPOOL_GETHOSTBYNAME
  398. * Removed greenio.Green_fileobject and refactored the code therein to be more efficient. Only call makefile() on sockets now; makeGreenFile() is deprecated. The main loss here is that of the readuntil method. Also, Green_fileobjects used to be auto-flushing; flush() must be called explicitly now.
  399. * Added epoll support
  400. * Improved documentation across the board.
  401. * New queue module, API-compatible with stdlib Queue
  402. * New debug module, used for enabling verbosity within Eventlet that can help debug applications or Eventlet itself.
  403. * Bugfixes in tpool, green.select, patcher
  404. * Deprecated coros.execute (use eventlet.spawn instead)
  405. * Deprecated coros.semaphore (use semaphore.Semaphore or semaphore.BoundedSemaphore instead)
  406. * Moved coros.BoundedSemaphore to semaphore.BoundedSemaphore
  407. * Moved coros.Semaphore to semaphore.Semaphore
  408. * Moved coros.event to event.Event
  409. * Deprecated api.tcp_listener, api.connect_tcp, api.ssl_listener
  410. * Moved get_hub, use_hub, get_default_hub from eventlet.api to eventlet.hubs
  411. * Renamed libevent hub to pyevent.
  412. * Removed previously-deprecated features tcp_server, GreenSSL, erpc, and trap_errors.
  413. * Removed saranwrap as an option for making db connections nonblocking in db_pool.
  414. 0.9.2
  415. =====
  416. * Bugfix for wsgi.py where it was improperly expecting the environ variable to be a constant when passed to the application.
  417. * Tpool.py now passes its tests on Windows.
  418. * Fixed minor performance issue in wsgi.
  419. 0.9.1
  420. =====
  421. * PyOpenSSL is no longer required for Python 2.6: use the eventlet.green.ssl module. 2.5 and 2.4 still require PyOpenSSL.
  422. * Cleaned up the eventlet.green packages and their associated tests, this should result in fewer version-dependent bugs with these modules.
  423. * PyOpenSSL is now fully wrapped in eventlet.green.OpenSSL; using it is therefore more consistent with using other green modules.
  424. * Documentation on using SSL added.
  425. * New green modules: ayncore, asynchat, SimpleHTTPServer, CGIHTTPServer, ftplib.
  426. * Fuller thread/threading compatibility: patching threadlocal with corolocal so coroutines behave even more like threads.
  427. * Improved Windows compatibility for tpool.py
  428. * With-statement compatibility for pools.Pool objects.
  429. * Refactored copyrights in the files, added LICENSE and AUTHORS files.
  430. * Added support for logging x-forwarded-for header in wsgi.
  431. * api.tcp_server is now deprecated, will be removed in a future release.
  432. * Added instructions on how to generate coverage reports to the documentation.
  433. * Renamed GreenFile to Green_fileobject, to better reflect its purpose.
  434. * Deprecated erpc method in tpool.py
  435. * Bug fixes in: wsgi.py, twistedr.py, poll.py, greenio.py, util.py, select.py, processes.py, selects.py
  436. 0.9.0
  437. =====
  438. * Full-duplex sockets (simultaneous readers and writers in the same process).
  439. * Remove modules that distract from the core mission of making it straightforward to write event-driven networking apps:
  440. httpd, httpc, channel, greenlib, httpdate, jsonhttp, logutil
  441. * Removed test dependency on sqlite, using nose instead.
  442. * Marked known-broken tests using nose's mechanism (most of these are not broken but are simply run in the incorrect context, such as threading-related tests that are incompatible with the libevent hub).
  443. * Remove copied code from python standard libs (in tests).
  444. * Added eventlet.patcher which can be used to import "greened" modules.
  445. 0.8.16
  446. ======
  447. * GreenSSLObject properly masks ZeroReturnErrors with an empty read; with unit test.
  448. * Fixed 2.6 SSL compatibility issue.
  449. 0.8.15
  450. ======
  451. * GreenSSL object no longer converts ZeroReturnErrors into empty reads, because that is more compatible with the underlying SSLConnection object.
  452. * Fixed issue caused by SIGCHLD handler in processes.py
  453. * Stopped supporting string exceptions in saranwrap and fixed a few test failures.
  454. 0.8.14
  455. ======
  456. * Fixed some more Windows compatibility problems, resolving EVT-37 :
  457. http://jira.secondlife.com/browse/EVT-37
  458. * waiting() method on Pool class, which was lost when the Pool implementation
  459. replaced CoroutinePool.
  460. 0.8.13
  461. ======
  462. * 2.6 SSL compatibility patch by Marcus Cavanaugh.
  463. * Added greenlet and pyopenssl as dependencies in setup.py.
  464. 0.8.12
  465. ======
  466. * The ability to resize() pools of coroutines, which was lost when the
  467. Pool implementation replaced CoroutinePool.
  468. * Fixed Cesar's issue with SSL connections, and furthermore did a
  469. complete overhaul of SSL handling in eventlet so that it's much closer
  470. to the behavior of the built-in libraries. In particular, users of
  471. GreenSSL sockets must now call shutdown() before close(), exactly
  472. like SSL.Connection objects.
  473. * A small patch that makes Eventlet work on Windows. This is the first
  474. release of Eventlet that works on Windows.
  475. 0.8.11
  476. ======
  477. Eventlet can now run on top of twisted reactor. Twisted-based hub is enabled automatically if
  478. twisted.internet.reactor is imported. It is also possible to "embed" eventlet into a twisted
  479. application via eventlet.twistedutil.join_reactor. See the examples for details.
  480. A new package, eventlet.twistedutil, is added that makes integration of twisted and eventlet
  481. easier. It has block_on function that allows to wait for a Deferred to fire and it wraps
  482. twisted's Protocol in a synchronous interface. This is similar to and is inspired by Christopher
  483. Armstrong's corotwine library. Thanks to Dan Pascu for reviewing the package.
  484. Another new package, eventlet.green, was added to provide some of the standard modules
  485. that are fixed not to block other greenlets. This is an alternative to monkey-patching
  486. the socket, which is impossible to do if you are running twisted reactor.
  487. The package includes socket, httplib, urllib2.
  488. Much of the core functionality has been refactored and cleaned up, including the removal
  489. of eventlet.greenlib. This means that it is now possible to use plain greenlets without
  490. modification in eventlet, and the subclasses of greenlet instead of the old
  491. eventlet.greenlib.GreenletContext. Calling eventlet.api.get_hub().switch() now checks to
  492. see whether the current greenlet has a "switch_out" method and calls it if so, providing the
  493. same functionality that the GreenletContext.swap_out used to. The swap_in behavior can be
  494. duplicated by overriding the switch method, and the finalize functionality can be duplicated
  495. by having a try: finally: block around the greenlet's main implementation. The eventlet.backdoor
  496. module has been ported to this new scheme, although it's signature had to change slightly so
  497. existing code that used the backdoor will have to be modified.
  498. A number of bugs related to improper scheduling of switch calls has been fixed.
  499. The fixed functions and classes include api.trampoline, api.sleep, coros.event,
  500. coros.semaphore, coros.queue.
  501. Many methods of greenio.GreenSocket were fixed to make its behavior more like that of a regular
  502. socket. Thanks to Marcin Bachry for fixing GreenSocket.dup to preserve the timeout.
  503. Added proc module which provides an easy way to subscribe to coroutine's results. This makes
  504. it easy to wait for a single greenlet or for a set of greenlets to complete.
  505. wsgi.py now supports chunked transfer requests (patch by Mike Barton)
  506. The following modules were deprecated or removed because they were broken:
  507. hubs.nginx, hubs.libev, support.pycurls, support.twisteds, cancel method of coros.event class
  508. The following classes are still present but will be removed in the future version:
  509. - channel.channel (use coros.Channel)
  510. - coros.CoroutinePool (use pool.Pool)
  511. saranwrap.py now correctly closes the child process when the referring object is deleted,
  512. received some fixes to its detection of child process death, now correctly deals with the in
  513. keyword, and it is now possible to use coroutines in a non-blocking fashion in the child process.
  514. Time-based expiry added to db_pool. This adds the ability to expire connections both by idleness
  515. and also by total time open. There is also a connection timeout option.
  516. A small bug in httpd's error method was fixed.
  517. Python 2.3 is no longer supported.
  518. A number of tests was added along with a script to run all of them for all the configurations.
  519. The script generates an html page with the results.
  520. Thanks to Brian Brunswick for investigation of popen4 badness (eventlet.process)
  521. Thanks to Marcus Cavanaugh for pointing out some coros.queue(0) bugs.
  522. The twisted integration as well as many other improvements were funded by AG Projects (http://ag-projects.com), thanks!
  523. 0.8.x
  524. =====
  525. Fix a CPU leak that would cause the poll hub to consume 100% CPU in certain conditions, for example the echoserver example. (Donovan Preston)
  526. Fix the libev hub to match libev's callback signature. (Patch by grugq)
  527. Add a backlog argument to api.tcp_listener (Patch by grugq)
  528. 0.7.x
  529. =====
  530. Fix a major memory leak when using the libevent or libev hubs. Timers were not being removed from the hub after they fired. (Thanks Agusto Becciu and the grugq). Also, make it possible to call wrap_socket_with_coroutine_socket without using the threadpool to make dns operations non-blocking (Thanks the grugq).
  531. It's now possible to use eventlet's SSL client to talk to eventlet's SSL server. (Thanks to Ryan Williams)
  532. Fixed a major CPU leak when using select hub. When adding a descriptor to the hub, entries were made in all three dictionaries, readers, writers, and exc, even if the callback is None. Thus every fd would be passed into all three lists when calling select regardless of whether there was a callback for that event or not. When reading the next request out of a keepalive socket, the socket would come back as ready for writing, the hub would notice the callback is None and ignore it, and then loop as fast as possible consuming CPU.
  533. 0.6.x
  534. =====
  535. Fixes some long-standing bugs where sometimes failures in accept() or connect() would cause the coroutine that was waiting to be double-resumed, most often resulting in SwitchingToDeadGreenlet exceptions as well as weird tuple-unpacking exceptions in the CoroutinePool main loop.
  536. 0.6.1: Added eventlet.tpool.killall. Blocks until all of the threadpool threads have been told to exit and join()ed. Meant to be used to clean up the threadpool on exit or if calling execv. Used by Spawning.
  537. 0.5.x
  538. =====
  539. "The Pycon 2008 Refactor": The first release which incorporates libevent support. Also comes with significant refactoring and code cleanup, especially to the eventlet.wsgi http server. Docstring coverage is much higher and there is new extensive documentation: http://wiki.secondlife.com/wiki/Eventlet/Documentation
  540. The point releases of 0.5.x fixed some bugs in the wsgi server, most notably handling of Transfer-Encoding: chunked; previously, it would happily send chunked encoding to clients which asked for HTTP/1.0, which isn't legal.
  541. 0.2
  542. =====
  543. Initial re-release of forked linden branch.
