nr added the comment: I added a new pull request. Martin, you are right I realized when looking through the code that just setting the file pointer to zero inside http lib might interfere with requests that don't have authentication enabled. The new pull requests does number 2.) of your

[issue5038] urrlib2/httplib doesn't reset file position between requests

Martin Panter added the comment: For 3.7+ (where iterable objects are supported), I suggest: 1. Document the problem as a limitation of handlers like AbstractBasicAuthHandler, and consider raising an exception instead of trying to upload a file or iterable a second time. 2. Clarify the

nr added the comment: PR 11843 should fix the issue in master, I didn't check python 2.6 or prior versions. The problem is that in the first request sent to HTTP service the POST data is sent correctly. After that the HTTP server responds with 401 and the request is resent but the mmap file

Martin Panter added the comment: Here is a demonstration script in case it helps. I haven’t tested it with versions before Python 2.6. Older versions send “Content-Length: 11”, but leave the server hanging trying to read the data. Newer versions (I presume since Issue 12319, 3.6+) send a

Martin Panter added the comment: Actually, I do not think any “Expect: 100-continue” headers are explicitly sent by the Python standard library. The Python client does not support waiting for a “100 Continue” response; see Issue 1346874. There is Issue 23740 opened about fixing or clarifying

Senthil Kumaran added the comment: I think, this requires triaging in terms of is the feature request still applicable. Except 100 is sent by httplib and the support for this was added few years ago, much later then this bug was originally raised. -- assignee: - orsenthil

[issue5038] urrlib2/httplib doesn't reset file position between requests

New submission from jan matejek jmate...@suse.cz: since 2.6 httplib supports reading from file-like objects. Now consider the following situation: There are two handlers in urrlib2, first is plain http, second is basic auth. I want to POST a file to a service, and pass the open file object as

Gabriel Genellina gagsl-...@yahoo.com.ar added the comment: This happens in other implementations too, not just urllib2. If the server supports it, the best way is to send an 'Expect: 100- Continue' header field before attempting to send the actual file. -- nosy: +gagenellina
