pycurl's Issues

Passing file pointers to libcurl may be dangerous

If libcurl and python are built with different crts, file pointers cannot be passed between them. This only affects python 2.

http://curl.haxx.se/mail/curlpython-2013-12/0026.html

There is already a conversion from file pointers to write methods for python 3 which can be used for python 2 on windows as well.

This fact should be documented for the benefit of anyone building pycurl/libcurl themselves. Also note that libcurl.dll cannot be swapped arbitrarily.

Pycurl and io.StringIO - pycurl.error: (23, 'Failed writing body')

Hi there,

I'm using pycurl 7.19.0 (libcurl/7.28.1 OpenSSL/1.0.1e zlib/1.2.7 libidn/1.25 libssh2/1.4.3) with Python 3.3.0

I set my write function as follows:

self._curl.setopt(pycurl.WRITEFUNCTION, self._response_body.write)

where self._response_body is io.StringIO object

The above write fails on large arrays of data, with an error like this:

pycurl.error: (23, 'Failed writing body (1457 != 1460)')

Have a look at a more detailed description and a workaround here

How to reproduce:

#!/usr/bin/env python3

import pycurl
from io import StringIO

if __name__ == "__main__":
    header = StringIO()
    body = StringIO()
    curl = pycurl.Curl()

    curl.setopt(pycurl.HEADERFUNCTION, header.write)
    curl.setopt(pycurl.WRITEFUNCTION, body.write)
    curl.setopt(pycurl.URL, "http://www.python.org/")

    curl.perform()

Can't install 7.19.0.3 with "pip install --pre pycurl"

Pip's --pre flag makes it use a more liberal parser of version numbers, which makes it parse "7.19.0.3.win32-py2.7" as a version number and download that zip even on non-windows platforms. This is important mainly because --pre is the default for dependencies installed via tox. I'm not sure what naming rules pip follows, but these windows zip files should either be renamed to follow the correct rules or moved so they are not linked from the pypi download_url (You might also be able to remove the download_url setting entirely now that the releases can be downloaded from pypi directly)

Extremely high CPU when I add MAX_SEND_SPEED_LARGE option.

My app uses PyCurl to upload multiple files one by one. It works all good with all cURL options and CPU consumption remains below 1%. When I add MAX_SEND_SPEED_LARGE option to throttle bandwidth, CPU consumption goes to 100%.

error installing on windows xp / python 3.3

i download the zip file from this github project
and tried to install but there wase an error ;

'Traceback (most recent call last):
File "setup.py", line 128, in
match = re.search(r'Version (\d+)', err.split("
TypeError: Type str doesn't support the buffer API'

After some searching, I found that, in py3k, The stdout & stderr are file objects working with bytes data so i fixed it with:

line 128 in setup.py becomes :
match = re.search(r'Version (\d+)', str(err).split("\n")[0])
or
match = re.search(r'Version (\d+)', err.decode(sys.stdout.encoding).split("\n")[0])

and that fixed the problem.
thank you for your efforts

User agent is fixed at compile time but includes libcurl version

Python 2.4 compatibility

If we claim python 2.4 support, we should ensure our code actually works under it.

In particular we use with statements in tests.

winbuild.py should give dll option to setup.py

Test suite broken on libcurl 7.33.0

Seem to be having an ssl certificate issue, check on travis.

Document requirement to use latest/specific official python releases with binary windows packages

Per http://curl.haxx.se/mail/curlpython-2014-05/0000.html and http://curl.haxx.se/mail/curlpython-2014-05/0011.html.

MSVC build broken

pycurl.h now has this:

#  warning \
  "libcurl was compiled with SSL support, ...

This is no good for MSVC. Should be:

# ifdef _MSC_VER
#   pragma message("libcurl was compiled with SSL support ...")
#  else

Convert documentation to restructured text

Review install and readme files, eliminate redundancies

Prohibit using wrong ssl library at runtime, test on travis

--help only broken on windows

See comments in 1ccd900.

Also, add setup.py --help to test suite.

Py_TYPE is 2.6+

Need to define it for older pythons.

dup/socketfunction does not work on windows

inet_ntop code breaks windows build

See comments in 751f428.

Make module init raise ImportError rather than destroy the interpreter

Make sure there is a test giving bytes and strings to setopt

PyObject_GC_Track check

http://docs.python.org/2/c-api/gcsupport.html

The collector can run at unexpected times so objects must be valid while being tracked. This should be called once all the fields followed by the tp_traverse handler become valid, usually near the end of the constructor.

Something is wrong

Hi Guys, It was a surprise for me to see such big activity in pycurl repo. I was thought that the project is frozen. I see you've uploaded a new version on pypi. Maybe there were many new versions of pycurl, but I noticed only the last one because it broked my tests.

I work on the website scraping framework called a Grab. I work on it for about 3 years and all this time I use pycurl as network backend. I have a large test suite (https://github.com/lorien/grab/tree/master/test) and recently it started throwing some errors https://travis-ci.org/lorien/grab/jobs/11910002. And then I went to pypi and noticed that last pycurl release is dated of this month.

The intresting fact, If I run tests on pycurl from http://githbub.com/lorien/pycurl (that is just copy of ubuntu pycurl with py3k patches) then I have no error. So, I think that you made some change to pycurl that breaks something inside it. Anyway, I just decided to open a new issue and update it when I have new info. I thought that you can also have some ideas about this.

My plan is to run Grab tests on revisions from your repo and find that revision is a root of the problem.

UPD: Could you also please point me to some blog post or just write here about how pycurl development process is organized. Is this repo an official repo of the pycurl project? Why does it have so few watchers and stars? Thanks.

Check that errstr really returns a string in Python 3

Extremely high CPU usage

Running this code in 10 threads causes high (80-90%) CPU usage:


url = 'https://www.google.com/'
buf = BytesIO()
c = pycurl.Curl()
c.setopt(c.URL, url)
c.setopt(c.CONNECTTIMEOUT, 10)
c.setopt(c.TIMEOUT, 20)
c.setopt(c.WRITEFUNCTION, buf.write)
c.perform()
response = buf.getvalue()
buf.close()

This only happens with https urls, http urls are fetched just fine.
Am I missing a setting or is this an expected behaviour?

Socket events test is intermittently failing

Reference leak with callback functions

When callback functions are used (e.g. pycurl.M_SOCKETFUNCTION), the pycurl object increments the reference count on the function, but as far as I can tell the reference count is never decremented, even if the callback is set to a new value or the pycurl object is closed. This leaks memory if curl handles are created and destroyed often.

Sample code which reproduces this leak can be found at http://stackoverflow.com/questions/23802020/process-memory-grows-huge-tornado-curlasynchttpclient

PY3: HTTP header string types

When setting headers with the HTTPHEADER option, pycurl expects a list of unicode strings. When receiving headers with the HEADERFUNCTION option, it returns byte strings. This is currently the main obstacle to using Tornado with pycurl on python 3 (see the last couple of messages in tornadoweb/tornado#671. To run the tests yourself, clone tornado and run "python -m tornado.test.runtests").

I believe the best way to handle headers is to use the str type in both python 2 and 3, so on python 3 the headers should be decoded as latin1 (gross, but that's what the spec says, and in practice they're always ascii anyway) before being passed to the HEADERFUNCTION. Alternately, I'd be OK with leaving things in bytes for HEADERFUNCTION as long as HTTPHEADER (and possibly other places) accepted bytes too.

PyObject *v = PyObject_GenericGetAttr(o, n);
assert_multi_state((CurlMultiObject *)o);

}
return v;

}

and in line 3816 also

Add an option to setup.py to specify ssl backend

But we need to figure it out at runtime if libcurl is dynamically linked?

Update manifest for added files under test directory

Also add a line item to release checklist to check manifest.

Winbuild does not recognize version changes

If a build is performed with libcurl version X, and succeeds, and subsequently version is changed to Y and another build is requested, winbuild thinks that because the state files exist, that libcurl version Y is built and installed, whereas this is not the case.

Winbuild has to check the state file and the libcurl directory for existence.
