  291. 0.9.17
  292. ======
  293. * ZeroMQ support calling send and recv from multiple greenthreads (thanks to Geoff Salmon)
  294. * SSL: unwrap() sends data, and so it needs trampolining (#104 thanks to Brandon Rhodes)

  311. * zmq module supports the NOBLOCK flag, thanks to rfk. (#76)
  312. * eventlet.wsgi has a debug flag which can be set to false to not send tracebacks to the client (per redbo's request)
  313. * Recursive GreenPipe madness forestalled by Soren Hansen (#77)
  314. * eventlet.green.ssl no longer busywaits on send()
  315. * EEXIST ignored in epoll hub (#80)
  316. * eventlet.listen's behavior on Windows improved, thanks to Nick Vatamaniuc (#83)
  317. * Timeouts raised within tpool.execute are propagated back to the caller (thanks again to redbo for being the squeaky wheel)
  318. 0.9.14
  319. ======
  320. * Many fixes to the ZeroMQ hub, which now requires version 2.0.10 or later. Thanks to Ben Ford.
  321. * ZeroMQ hub no longer depends on pollhub, and thus works on Windows (thanks, Alexey Borzenkov)
  322. * Better handling of connect errors on Windows, thanks again to Alexey Borzenkov.
  323. * More-robust Event delivery, thanks to Malcolm Cleaton
  324. * wsgi.py now distinguishes between an empty query string ("") and a non-existent query string (no entry in environ).
  325. * wsgi.py handles ipv6 correctly (thanks, redbo)
  326. * Better behavior in tpool when you give it nonsensical numbers, thanks to R. Tyler for the nonsense. :)
  327. * Fixed importing on 2.5 (#73, thanks to Ruijun Luo)
  328. * Hub doesn't hold on to invalid fds (#74, thanks to Edward George)
  329. * Documentation for eventlet.green.zmq, courtesy of Ben Ford
  330. 0.9.13
  331. ======
  332. * ZeroMQ hub, and eventlet.green.zmq make supersockets green. Thanks to Ben Ford!
  333. * eventlet.green.MySQLdb added. It's an interface to MySQLdb that uses tpool to make it appear nonblocking
  334. * Greenthread affinity in tpool. Each greenthread is assigned to the same thread when using tpool, making it easier to work with non-thread-safe libraries.
  335. * Eventlet now depends on greenlet 0.3 or later.
  336. * Fixed a hang when using tpool during an import causes another import. Thanks to mikepk for tracking that down.
  337. * Improved websocket draft 76 compliance, thanks to Nick V.
  338. * Rare greenthread.kill() bug fixed, which was probably brought about by a bugfix in greenlet 0.3.
  339. * Easy_installing eventlet should no longer print an ImportError about greenlet
  340. * Support for serving up SSL websockets, thanks to chwagssd for reporting #62
  341. * eventlet.wsgi properly sets 'wsgi.url_scheme' environment variable to 'https', and 'HTTPS' to 'on' if serving over ssl
  342. * Blocking detector uses setitimer on 2.6 or later, allowing for sub-second block detection, thanks to rtyler.
  343. * Blocking detector is documented now, too
  344. * socket.create_connection properly uses dnspython for nonblocking dns. Thanks to rtyler.
  345. * Removed EVENTLET_TPOOL_DNS, nobody liked that. But if you were using it, install dnspython instead. Thanks to pigmej and gholt.
  346. * Removed _main_wrapper from greenthread, thanks to Ambroff adding keyword arguments to switch() in 0.3!
  347. 0.9.12
  348. ======
  349. * 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.
  350. * Removed circular import in twistedr.py
  351. * Added websocket multi-user chat example
  352. * Not using exec() in green modules anymore.
  353. * eventlet.green.socket now contains all attributes of the stdlib socket module, even those that were left out by bugs.
  354. * Eventlet.wsgi doesn't call print anymore, instead uses the logfiles for everything (it used to print exceptions in one place).
  355. * Eventlet.wsgi properly closes the connection when an error is raised
  356. * Better documentation on eventlet.event.Event.send_exception
  357. * Adding websocket.html to tarball so that you can run the examples without checking out the source
  358. 0.9.10
  359. ======
  360. * 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.
  361. * Full test suite passes on Python 2.7.
  362. * Tests no longer depend on simplejson for >2.6.
  363. * Potential-bug fixes in patcher (thanks to Schmir, and thanks to Hudson)
  364. * Websockets work with query strings (thanks to mcarter)
  365. * WSGI posthooks that get called after the request completed (thanks to gholt, nice docs, too)
  366. * Blocking detector merged -- use it to detect places where your code is not yielding to the hub for > 1 second.
  367. * tpool.Proxy can wrap callables
  368. * Tweaked Timeout class to do something sensible when True is passed to the constructor
  369. 0.9.9
  370. =====
  371. * A fix for monkeypatching on systems with psycopg version 2.0.14.
  372. * Improved support for chunked transfers in wsgi, plus a bunch of tests from schmir (ported from gevent by redbo)
  373. * A fix for the twisted hub from Favo Yang
  374. 0.9.8
  375. =====
  376. * Support for psycopg2's asynchronous mode, from Daniele Varrazzo
  377. * 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
  378. * Added wrap_ssl convenience method, meaning that we truly no longer need api or util modules.
  379. * 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.
  380. * Cleaner monkey_patch API: the "all" keyword is no longer necessary.
  381. * Pool objects have a more convenient constructor -- no more need to subclass
  382. * amajorek's reimplementation of GreenPipe
  383. * Many bug fixes, major and minor.
  384. 0.9.7
  385. =====
  386. * GreenPipe is now a context manager (thanks, quad)
  387. * tpool.Proxy supports iterators properly
  388. * bug fixes in eventlet.green.os (thanks, Benoit)
  389. * much code cleanup from Tavis
  390. * a few more example apps
  391. * multitudinous improvements in Py3k compatibility from amajorek
  392. 0.9.6
  393. =====
  394. * new EVENTLET_HUB environment variable allows you to select a hub without code
  395. * improved GreenSocket and GreenPipe compatibility with stdlib
  396. * bugfixes on GreenSocket and GreenPipe objects
  397. * code coverage increased across the board
  398. * Queue resizing
  399. * internal DeprecationWarnings largely eliminated
  400. * tpool is now reentrant (i.e., can call tpool.execute(tpool.execute(foo)))
  401. * more reliable access to unpatched modules reduces some race conditions when monkeypatching
  402. * completely threading-compatible corolocal implementation, plus tests and enthusiastic adoption
  403. * tests stomp on each others' toes less
  404. * performance improvements in timers, hubs, greenpool
  405. * Greenlet-aware profile module courtesy of CCP
  406. * support for select26 module's epoll
  407. * better PEP-8 compliance and import cleanup
  408. * new eventlet.serve convenience function for easy TCP servers
  409. 0.9.5
  410. =====
  411. * support psycopg in db_pool
  412. * smart patcher that does the right patching when importing without needing to understand plumbing of patched module
  413. * patcher.monkey_patch() method replacing util.wrap_*
  414. * monkeypatch threading support
  415. * removed api.named
  416. * imported timeout module from gevent, replace exc_after and with_timeout()
  417. * replace call_after with spawn_after; this is so that users don't see the Timer class
  418. * added cancel() method to GreenThread to support the semantic of "abort if not already in the middle of something"
  419. * eventlet.green.os with patched read() and write(), etc
  420. * moved stuff from wrap_pipes_with_coroutine_pipe into green.os
  421. * eventlet.green.subprocess instead of eventlet.processes

  424. * deprecate api.py completely
  425. * deprecate util.py completely
  426. * deprecate saranwrap
  427. * performance improvements in the hubs
  428. * much better documentation overall
  429. * new convenience functions: eventlet.connect and eventlet.listen. Thanks, Sergey!
  430. 0.9.4
  431. =====
  432. * Deprecated coros.Queue and coros.Channel (use queue.Queue instead)
  433. * Added putting and getting methods to queue.Queue.
  434. * Added eventlet.green.Queue which is a greened clone of stdlib Queue, along with stdlib tests.
  435. * Changed __init__.py so that the version number is readable even if greenlet's not installed.
  436. * Bugfixes in wsgi, greenpool
  437. 0.9.3
  438. =====
  439. * 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.
  440. * Proc module deprecated in favor of greenthread
  441. * New module greenthread, with new class GreenThread.
  442. * New GreenPool class that replaces pool.Pool.
  443. * Deprecated proc module (use greenthread module instead)
  444. * tpooled gethostbyname is configurable via environment variable EVENTLET_TPOOL_GETHOSTBYNAME
  445. * 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.
  446. * Added epoll support
  447. * Improved documentation across the board.
  448. * New queue module, API-compatible with stdlib Queue
  449. * New debug module, used for enabling verbosity within Eventlet that can help debug applications or Eventlet itself.
  450. * Bugfixes in tpool, green.select, patcher
  451. * Deprecated coros.execute (use eventlet.spawn instead)
  452. * Deprecated coros.semaphore (use semaphore.Semaphore or semaphore.BoundedSemaphore instead)
  453. * Moved coros.BoundedSemaphore to semaphore.BoundedSemaphore
  454. * Moved coros.Semaphore to semaphore.Semaphore
  455. * Moved coros.event to event.Event
  456. * Deprecated api.tcp_listener, api.connect_tcp, api.ssl_listener
  457. * Moved get_hub, use_hub, get_default_hub from eventlet.api to eventlet.hubs
  458. * Renamed libevent hub to pyevent.
  459. * Removed previously-deprecated features tcp_server, GreenSSL, erpc, and trap_errors.
  460. * Removed saranwrap as an option for making db connections nonblocking in db_pool.
  461. 0.9.2
  462. =====
  463. * Bugfix for wsgi.py where it was improperly expecting the environ variable to be a constant when passed to the application.
  464. * Tpool.py now passes its tests on Windows.
  465. * Fixed minor performance issue in wsgi.
  466. 0.9.1
  467. =====
  468. * PyOpenSSL is no longer required for Python 2.6: use the eventlet.green.ssl module. 2.5 and 2.4 still require PyOpenSSL.
  469. * Cleaned up the eventlet.green packages and their associated tests, this should result in fewer version-dependent bugs with these modules.
  470. * PyOpenSSL is now fully wrapped in eventlet.green.OpenSSL; using it is therefore more consistent with using other green modules.
  471. * Documentation on using SSL added.
  472. * New green modules: ayncore, asynchat, SimpleHTTPServer, CGIHTTPServer, ftplib.
  473. * Fuller thread/threading compatibility: patching threadlocal with corolocal so coroutines behave even more like threads.
  474. * Improved Windows compatibility for tpool.py
  475. * With-statement compatibility for pools.Pool objects.
  476. * Refactored copyrights in the files, added LICENSE and AUTHORS files.
  477. * Added support for logging x-forwarded-for header in wsgi.
  478. * api.tcp_server is now deprecated, will be removed in a future release.
  479. * Added instructions on how to generate coverage reports to the documentation.
  480. * Renamed GreenFile to Green_fileobject, to better reflect its purpose.
  481. * Deprecated erpc method in tpool.py
  482. * Bug fixes in: wsgi.py, twistedr.py, poll.py, greenio.py, util.py, select.py, processes.py, selects.py
  483. 0.9.0
  484. =====
  485. * Full-duplex sockets (simultaneous readers and writers in the same process).
  486. * Remove modules that distract from the core mission of making it straightforward to write event-driven networking apps:
  487. httpd, httpc, channel, greenlib, httpdate, jsonhttp, logutil
  488. * Removed test dependency on sqlite, using nose instead.
  489. * 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).
  490. * Remove copied code from python standard libs (in tests).
  491. * Added eventlet.patcher which can be used to import "greened" modules.
  492. 0.8.16
  493. ======
  494. * GreenSSLObject properly masks ZeroReturnErrors with an empty read; with unit test.
  495. * Fixed 2.6 SSL compatibility issue.
  496. 0.8.15
  497. ======
  498. * GreenSSL object no longer converts ZeroReturnErrors into empty reads, because that is more compatible with the underlying SSLConnection object.
  499. * Fixed issue caused by SIGCHLD handler in processes.py
  500. * Stopped supporting string exceptions in saranwrap and fixed a few test failures.
  501. 0.8.14
  502. ======
  503. * Fixed some more Windows compatibility problems, resolving EVT-37 :
  504. http://jira.secondlife.com/browse/EVT-37
  505. * waiting() method on Pool class, which was lost when the Pool implementation
  506. replaced CoroutinePool.
  507. 0.8.13
  508. ======
  509. * 2.6 SSL compatibility patch by Marcus Cavanaugh.
  510. * Added greenlet and pyopenssl as dependencies in setup.py.
  511. 0.8.12
  512. ======
  513. * The ability to resize() pools of coroutines, which was lost when the
  514. Pool implementation replaced CoroutinePool.
  515. * Fixed Cesar's issue with SSL connections, and furthermore did a
  516. complete overhaul of SSL handling in eventlet so that it's much closer
  517. to the behavior of the built-in libraries. In particular, users of
  518. GreenSSL sockets must now call shutdown() before close(), exactly
  519. like SSL.Connection objects.
  520. * A small patch that makes Eventlet work on Windows. This is the first
  521. release of Eventlet that works on Windows.
  522. 0.8.11
  523. ======
  524. Eventlet can now run on top of twisted reactor. Twisted-based hub is enabled automatically if
  525. twisted.internet.reactor is imported. It is also possible to "embed" eventlet into a twisted
  526. application via eventlet.twistedutil.join_reactor. See the examples for details.
  527. A new package, eventlet.twistedutil, is added that makes integration of twisted and eventlet
  528. easier. It has block_on function that allows to wait for a Deferred to fire and it wraps
  529. twisted's Protocol in a synchronous interface. This is similar to and is inspired by Christopher
  530. Armstrong's corotwine library. Thanks to Dan Pascu for reviewing the package.
  531. Another new package, eventlet.green, was added to provide some of the standard modules
  532. that are fixed not to block other greenlets. This is an alternative to monkey-patching
  533. the socket, which is impossible to do if you are running twisted reactor.
  534. The package includes socket, httplib, urllib2.
  535. Much of the core functionality has been refactored and cleaned up, including the removal
  536. of eventlet.greenlib. This means that it is now possible to use plain greenlets without
  537. modification in eventlet, and the subclasses of greenlet instead of the old
  538. eventlet.greenlib.GreenletContext. Calling eventlet.api.get_hub().switch() now checks to
  539. see whether the current greenlet has a "switch_out" method and calls it if so, providing the
  540. same functionality that the GreenletContext.swap_out used to. The swap_in behavior can be
  541. duplicated by overriding the switch method, and the finalize functionality can be duplicated
  542. by having a try: finally: block around the greenlet's main implementation. The eventlet.backdoor
  543. module has been ported to this new scheme, although it's signature had to change slightly so
  544. existing code that used the backdoor will have to be modified.
  545. A number of bugs related to improper scheduling of switch calls has been fixed.
  546. The fixed functions and classes include api.trampoline, api.sleep, coros.event,
  547. coros.semaphore, coros.queue.
  548. Many methods of greenio.GreenSocket were fixed to make its behavior more like that of a regular
  549. socket. Thanks to Marcin Bachry for fixing GreenSocket.dup to preserve the timeout.
  550. Added proc module which provides an easy way to subscribe to coroutine's results. This makes
  551. it easy to wait for a single greenlet or for a set of greenlets to complete.
  552. wsgi.py now supports chunked transfer requests (patch by Mike Barton)
  553. The following modules were deprecated or removed because they were broken:
  554. hubs.nginx, hubs.libev, support.pycurls, support.twisteds, cancel method of coros.event class
  555. The following classes are still present but will be removed in the future version:
  556. - channel.channel (use coros.Channel)
  557. - coros.CoroutinePool (use pool.Pool)
  558. saranwrap.py now correctly closes the child process when the referring object is deleted,
  559. received some fixes to its detection of child process death, now correctly deals with the in
  560. keyword, and it is now possible to use coroutines in a non-blocking fashion in the child process.
  561. Time-based expiry added to db_pool. This adds the ability to expire connections both by idleness
  562. and also by total time open. There is also a connection timeout option.
  563. A small bug in httpd's error method was fixed.
  564. Python 2.3 is no longer supported.
  565. A number of tests was added along with a script to run all of them for all the configurations.
  566. The script generates an html page with the results.
  567. Thanks to Brian Brunswick for investigation of popen4 badness (eventlet.process)
  568. Thanks to Marcus Cavanaugh for pointing out some coros.queue(0) bugs.
  569. The twisted integration as well as many other improvements were funded by AG Projects (http://ag-projects.com), thanks!
  570. 0.8.x
  571. =====
  572. Fix a CPU leak that would cause the poll hub to consume 100% CPU in certain conditions, for example the echoserver example. (Donovan Preston)
  573. Fix the libev hub to match libev's callback signature. (Patch by grugq)
  574. Add a backlog argument to api.tcp_listener (Patch by grugq)
  575. 0.7.x
  576. =====
  577. 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).
  578. It's now possible to use eventlet's SSL client to talk to eventlet's SSL server. (Thanks to Ryan Williams)
  579. 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.
  580. 0.6.x
  581. =====
  582. 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.
  583. 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.
  584. 0.5.x
  585. =====
  586. "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
  587. 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.
  588. 0.2
  589. =====
  590. Initial re-release of forked linden branch.
