[issue25701] Document that tp_setattro and tp_setattr are used for deleting attributes
by Serhiy Storchaka 23 Nov '15

23 Nov '15

New submission from Serhiy Storchaka: tp_setattro and tp_setattr fields of PyTypeObject are used for deleting attributes. In this case the third argument is NULL. This should be documented. Not awareness of this can cause a segmentation fail (for example see issue25698). ---------- assignee: docs@python components: Documentation messages: 255130 nosy: docs@python, serhiy.storchaka priority: normal severity: normal status: open title: Document that tp_setattro and tp_setattr are used for deleting attributes type: crash versions: Python 2.7, Python 3.4, Python 3.5, Python 3.6 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue25701> _______________________________________

Multiple bugs in email package and documentation - Python 3.4
by Ervin Hegedüs 22 Nov '15

22 Nov '15

Hi, looks like I've found a complex, and connected bug in 'email' package. Bug 1: ===== I've read the documentation and examples: https://docs.python.org/3.4/library/email-examples.html I've looked up this example (copy and paste, replace the addresses): https://docs.python.org/3.4/library/email-examples.html#examples-using-the-… and this example gives a bug: (after several lines, the end of the stack is this) File "/usr/lib/python3.4/email/_header_value_parser.py", line 629, in __str__ return quote_string(''.join(str(x) for x in self)) File "/usr/lib/python3.4/email/_header_value_parser.py", line 629, in <genexpr> return quote_string(''.join(str(x) for x in self)) RuntimeError: maximum recursion depth exceeded while getting the str of an object Okay, I've commented out the file write method, in line 50. and 51 - then script terminated normally. Bug 2: ===== I've received the e-mail, but the MIME tree of message is completely wrong. I think the original author would like to make a html mail (multipart/alternative), with embedded image. The regular tree of a html mail is this: I 1 <no description> [multipa/alternativ, 7bit, 0,5K] I 2 ├─><nodescription> [text/plain, quoted, utf-8, 0,1K] I 3 └─><nodescription> [text/html, quoted, utf-8, 0,2K] I 4 attached_image.png [image/png, base64, 43K] but the script in the example gives this tree: I 1 <no description> [multipa/alternativ, 7bit, 101K] I 2 ├─><no description> [text/plain, 8bit, utf-8, 0,1K] I 3 └─><no description> [multipa/related, 7bit, 101K] I 4 ├─><no description> [text/html, quoted, utf-8, 0,3K] I 5 └─><no description> [image/jpeg, base64, 100K] So, the problem is, in a general MUA (Thunderbird, any webmail client...) the image is not visible, but mail contains it. Bug 3: ===== The attached image is "pseduo" base64 encoded. The encode function is defined in email/contenmanager.py: 129 # XXX: This is a cleaned-up version of base64mime.body_encode. It would 130 # be nice to drop both this and quoprimime.body_encode in favor of 131 # enhanced binascii routines that accepted a max_line_length parameter. 132 def _encode_base64(data, max_line_length): 133 encoded_lines = [] 134 unencoded_bytes_per_line = max_line_length * 3 // 4 135 for i in range(0, len(data), unencoded_bytes_per_line): 136 thisline = data[i:i+unencoded_bytes_per_line] 137 encoded_lines.append(binascii.b2a_base64(thisline).decode('ascii')) 138 return ''.join(encoded_lines) But this code generates this form of base64: --===============8598821442385181731== Content-Type: image/jpeg Content-Transfer-Encoding: base64 Content-ID: <20151122160934.12051.88999(a)myhost.com> MIME-Version: 1.0 Content-Disposition: inline /9j/4R1zRXhpZgAASUkqAAgAAAAMAAABAwABAAAAWQIAAAEBAwABAAAA3AAAAAIBAwADAAAAngAAAA== BgEDAAEAAAACAAAAEgEDAAEAAAABAAAAFQEDAAEAAAADAAAAGgEFAAEAAACkAAAAGwEFAAEAAACsAA== I don't know, why had been created a new encoder here, because there is the email/encoders.py module, which contains a correct base64 encoder. With that, I've got this form (with same image): --===============6414765018955620772== Content-Type: image/jpeg Content-Transfer-Encoding: base64 Content-ID: <20151122161400.14276.87008(a)myhost.com> MIME-Version: 1.0 Content-Disposition: inline /9j/4R1zRXhpZgAASUkqAAgAAAAMAAABAwABAAAAWQIAAAEBAwABAAAA3AAAAAIBAwADAAAAngAA AAYBAwABAAAAAgAAABIBAwABAAAAAQAAABUBAwABAAAAAwAAABoBBQABAAAApAAAABsBBQABAAAA I've checked this routine with another MIME tree, where image should be visible, but the user agent could't show that. Whit the correct tree and correct encoding, the e-mail visible as correctly, with inline image. I don't know, how can I report this connected bugs? I have a good and working example - but it uses not exactly modules, than in example, however it builds a correct e-mail message. (I don't know, what does it mean the "Provisional API" - and what is the eventual?) Thanks, a.

struct package documentation bug
by Colton Williams 20 Nov '15

20 Nov '15

The documentation for the `struct` package https://docs.python.org/2/library/struct.html <https://docs.python.org/2/library/struct.html> indicates that using ‘l’ (that’s an ‘l’ as in leopard) as the format character for the pack function will return 4 bytes. Using that format character appears to actually return 8 bytes of data.

[issue25594] enum docs outdated re attribute access
by SilentGhost 20 Nov '15

20 Nov '15

New submission from SilentGhost: In enum docs[0], there is a suggestion that the attribute access on members should raise an AttributeError: >>> Color.red.blue Traceback (most recent call last): ... AttributeError: 'Color' object has no attribute 'blue' which is demonstrably wrong in either 3.5 or 3.6. I presume that's a doc issue and I'd be glad to propose the patch as soon as someone more familiar with the module could confirm that.
