Suggested Resolution: Remove the line that calls php_error_docref to raise the error. There's also a minor side issue with urllib3 that it raises a ValueError for values < 0 stating that timeout can be set to 0 or greater. offbyone commented Jul 30, 2015 I'll do that & report back.

The error is below in full detail, but in short, send() in requests is emitting ConnectionError: ('Connection aborted.', error(115, 'Operation now in progress')) Python=2.7 Requests=2.7.0 The parameters being passed in to The patch only touches functions pg_send_query() and pg_send_query_params(), so any possible regression should affect only those methods. Note that the result does not say whether any input data was actually collected. If the query string is too long (in bytes), the pg_send_query() will fail because of implementation bug (missing flush before touching counnection).
Due to the large number of connected subscribers and int- exchange links, switching fabrics in telephone exchanges have to serve a great number of input and output ports. I'm not in favor of silently doing things users might not expect. Omitting the parameter will default the read timeout to the system default, probably `the global default timeout in socket.py `_. google.com/… –Frank Farmer Oct 14 '09 at 15:32 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook

requests collaborator sigmavirus24 commented Sep 1, 2015 ValueError is fine by me. see here requests collaborator Lukasa commented Sep 3, 2015 @kevinburke There is one test (test.with_dummyserver.test_connectionpool.TestConnectionPool.test_total_timeout) that appears to expect a read timeout of 0 to work (specifically, to raise EAGAIN). For example, let's say that you're writing a web browser. Handling many sockets at once using select() Next 6.5.
When you issue a call to connect(), your program doesn't regain control until either the connection is made, or an error occurs. However, there are times when its useful to be able to call send(), recv(), connect(), accept(), etc without having to wait for the result. In a vanilla requests/urllib3 that's really only a very small number of lines of code: requests.packages.urllib3.util.connection:68 to requests.packages.urllib3.util.connection:78. http://fortecrm.net/cannot-set/cannot-set-connection-to-blocking-mode-in-unknown.html When you run them, the connection "blocks" until the operation is complete.
requests collaborator Lukasa commented Jul 14, 2016 Yup, but I think that test is wrong. From that time, many research was conducted in this field. You try to connect to a web server, but the server isn't responding.
The connect() API is a little different.
The PG team have apparently solved this issue, so I've dropped persistence as it was cluttering up my system unnecessarily. share|improve this answer answered May 15 '09 at 11:07 Tometzky 11.9k12843 You should know, that link doesn't exactly pull any documents back... –NotMe Oct 13 '09 at 20:33 For what it's worth, this is the code calling requests: reply = requests.request(verb.lower(), uri.geturl(), data=http_data, verify=verify_cert, cert=cert, headers=headers, auth=http_auth, timeout=self._timeout, proxies=self._proxies) Doesn't seem to be anything there about sockets :/ requests Antonym for Nourish Why there are no approximation algorithms for SAT and other decision problems?
Note that PQgetResult will block only if a command is active and the necessary response data has not yet been read by PQconsumeInput. The function's parameters are handled identically to PQexecParams. When you call send(), it puts the data into a buffer, and as it's read by the remote site, it's removed from the buffer. http://fortecrm.net/cannot-set/cannot-set-connection-to-blocking-mode-codeigniter.html Jul 30, 2015 requests collaborator sigmavirus24 commented Jul 30, 2015 @Lukasa I was thinking along the lines of if not isinstance(timeout, (tuple, int, float)): raise ValueError() If people have something that
How to set up the default value for checkbox in slds What does an expansion in early december mean for the standard format? However, if you're not passing explicit socket options then we aren't putting the socket in non-blocking mode, and it's hard to see why you'd do that (lots of stuff would go A client that uses PQsendQuery/PQgetResult can also attempt to cancel a command that is still being processed by the server; see Section 31.5. Like PQdescribePortal, it will not work on 2.0-protocol connections.
Whether it's on SO's side or google's, I'm not sure. There are also PQsendQueryParams, PQsendPrepare, PQsendQueryPrepared, PQsendDescribePrepared, and PQsendDescribePortal, which can be used with PQgetResult to duplicate the functionality of PQexecParams, PQprepare, PQexecPrepared, PQdescribePrepared, and PQdescribePortal respectively. If it becomes read-ready, call PQconsumeInput, then call PQflush again. Pass a (connect, read) " "timeout tuple, or a single float to set " "both timeouts to the same value".format(timeout)) raise ValueError(err) else: timeout = TimeoutSauce(connect=timeout, read=timeout) try: if not chunked:
PQsetnonblocking Sets the nonblocking status of the connection. Lukasa changed the title from (Requests 2.7.0) getting error(115, 'Operation now in progress')) on connect to timeout=False puts the socket in non-blocking mode, causing weird errors. PQisnonblocking Returns the blocking status of the database connection. This fits with your observation that your INSERT statements get executed.
