* greendns: don't contact nameservers if one entry is returned from hosts fileDaniel Alvarez2018-08-032-19/+83
| | | | | | | | | | | | | | getaddrinfo() behaves differently from the standard implementation as it will try to contact nameservers if only one (IPv4 or IPv6) entry is returned from /etc/hosts file. This patch avoids getaddrinfo() querying nameservers if at least one entry is fetched through the hosts file to match the behavior of the original socket.getaddrinfo() implementation.

* wsgi: Use byte strings on py2 and unicode strings on py3Tim Burke2018-07-252-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Closes #488; for some additional context, see #468 and #467. PEP-0333 says [1] > all strings referred to in this specification **must** be of type ``str`` but muddied that message earlier with a bunch of talk about > all strings passed to or from the server must be standard Python byte > strings, not Unicode objects PEP-3333 sought to clarify [2] with > WSGI therefore defines two kinds of "string": > > * "Native" strings (which are always implemented using the type > named ``str``) that are used for request/response headers and > metadata > > * "Bytestrings" (which are implemented using the ``bytes`` type > in Python 3, and ``str`` elsewhere), that are used for the bodies > of requests and responses (e.g. POST/PUT input data and HTML page > outputs). > > Do not be confused however: even if Python's ``str`` type is actually > Unicode "under the hood", the *content* of native strings must > still be translatable to bytes via the Latin-1 encoding! And later, in "Unicode Issues" [3], it adds > For values referred to in this specification as "bytestrings" > (i.e., values read from ``wsgi.input``, passed to ``write()`` > or yielded by the application), the value **must** be of type > ``bytes`` under Python 3, and ``str`` in earlier versions of > Python. So the upshot seems to be - All request and response bodies must be bytes, regardless of Python version. - All headers and other WSGI environment keys need to be native strings; i.e. bytes strings on Python 2 and unicode strings on Python 3.

* wsgi: Don't strip all Unicode whitespace from headers on py3 (#504)Tim Burke2018-07-062-1/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An application that wants to accept UTF-8 header values on Python 2 can do so fairly easily: since str is bytes, it can decode from UTF-8 directly and return appropriate errors if that decoding fails. On Python 3, it gets a little more interesting. Since str is unicode, the bytes-on-the-wire are decoded as Latin-1 before being put in the WSGI environment, so the application must encode as Latin-1 then decode as UTF-8. For the most part, this Just Works as the transformation should be lossless. Sometimes, however, headers get truncated on py3. This is the result of a difference in how .strip() behaves for bytes vs unicode -- in particular, there are some unicode characters that are considered whitespace whose Latin-1 encoded byte string is not: >>> [x for i in range(256) for x in (chr(i),) ... if x.isspace() and not x.encode('latin1').isspace()] ['\x1c', '\x1d', '\x1e', '\x1f', '\x85', '\xa0'] Looking at RFC 7230, it defines header fields as a case-insensitive field name followed by a colon (":"), optional leading whitespace, the field value, and optional trailing whitespace where "whitespace" is limited to SP or HTAB. So, let's just strip *those* from header values. Note that (some versions of?) py2's mimetools.Message includes the trailing CRLF, so strip that, too. https://github.com/eventlet/eventlet/pull/504
* pools: put to empty pool would block sometimesSam Merritt2018-07-034-9/+73
| | | | | | | | | | | | | | | | | | | If you have a pool with no free items, one greenthread blocked in pool.get(), and then you call pool.put(item), sometimes the put will block. This happens when the greenthread blocked in pool.get() has a pending timeout. The timeout's timer has fired, the call to throw() has been scheduled, but throw() has not actually run yet. In pool.put(), we see a waiting getter, so we do a blocking self.channel.put()... but when the getter runs, it unwinds its stack and does not take the item, leaving the caller of pool.put() blocked despite there being enough free space. This commit fixes that by (a) making LightQueue.put() and .get() work with 0-length queues, even with timeouts, and (b) checking for queue.Full in Pool.put() and handling it correctly. https://github.com/eventlet/eventlet/pull/495

* greendns: full comment lines were not skipped; Thanks to nat-goodspeednat-goodspeed2018-05-072-8/+14
| | | | | | | | | | | | `greendns.HostsResolver.LINES_RE` doesn't admit the possibility of a comment starting at the beginning of a line. This has been ignored since `is_ipv4_addr()` and `is_ipv6_addr()` catch `dns.exception.SyntaxError` and return `False`. But in a runtime environment that encounters #413, `dns.exception.SyntaxError` is not caught, and the import fails. Changing '+' to '*' allows `HostsResolver._readlines()` to recognize and skip comment lines. greendns.HostsResolver._readlines(), a purely internal method, now returns an itertools generator rather than a list. Change relevant asserts to build a list before comparing.

* patcher: workaround for monotonic "no suitable implementation"patcher-gethub-401Geoffrey Thomas2017-08-262-0/+12
| | | | | | | | | | | | | | In some cases -- notably with Python 2.7.13 and the default hub -- the process of importing the hub involves calling code in a module we monkey-patch. This leads to recursive imports: the first eventlet function will call get_hub(), which will try to import the hub, which will call a monkey-patched module, which will call get_hub() and try to import the hub again. To avoid this, make sure the hub is fully imported before monkey-patching anything. https://github.com/eventlet/eventlet/issues/401
