[issue9298] binary email attachment issue with base64 encoding

[Vance Unruh]

New submission from Vance Unruh :

I'm using Python to email a text version and a PDF version of a report. The 
standard way of doing things does not work with Vista's Mail program, but works 
fine with Mail on OSX. So, I don't know if this is a Python or a Vista Mail 
bug. By standard way, I mean:

# Add the attached PDF:
part = MIMEApplication(pdf,"pdf")
part.add_header('Content-Disposition', 'attachment', filename=pdfFile)
msg.attach(part)


To fix the problem, I changed C:\Python31\Lib\email\encoders.py to use 
encodebytes instead of b64encode in order to get mail on Windows Vista to 
correctly interpret the attachment. This splits the base64 encoding into many 
lines of some fixed lenth.

I can achieve the same thing adding the attachment by hand with the following 
code:

from email.mime.base import MIMEBase
part = MIMEBase("application","pdf")
part.add_header('Content-Transfer-Encoding', 'base64') 
part.set_payload(str(base64.encodebytes(pdf),'ascii'))
msg.attach(part)

Seems like I shouldn't need to know this much.

I'm new to Python and this is the first bug I have submitted, so if you need 
additional information, please let me know.

Can you add unit tests? Also, the second chunk in your patch is just a style

[issue9297] SMTP with Sqlite3 file attachment

[Murilo da Silva]

New submission from Murilo da Silva :

I'm sending e-mail using SMTP. This e-mail is sent with an Sqlite3 database 
attached.
When I send the e-mail in the same domain the attachment arrives OK, but if I 
send it to a different domain it comes crashed!!
The file is added with some base64 code...I don't have any ideia why!

The code mail.py:

import smtplib
import os
import mimetypes
import base64

from email import encoders
from email.message import Message
from email.mime.base import MIMEBase
from email.mime.nonmultipart import MIMENonMultipart
from email.mime.multipart import MIMEMultipart
from email.mime.application import MIMEApplication
from email.mime.audio import MIMEAudio
from email.mime.image import MIMEImage
from email.mime.message import MIMEMessage
from email.mime.text import MIMEText

class SendMail:
def __init__(self):
self.body = []
self.attachments = []

def add_body(self, _text, _subtype='plain', _charset='us-ascii'):
part = MIMEText(_text+"\n", _subtype, _charset)
self.body.append(part)

def add_attach(self, _file_path, _subtype='octet-stream', 
_encoder=encoders.encode_base64, **_params):
path = _file_path
ctype, encoding = mimetypes.guess_type(path)
if ctype is None or encoding is not None:
ctype = 'application/octet-stream'
maintype, subtype = ctype.split('/', 1)
if maintype == 'text':
fp = open(path)
part = MIMEText(fp.read(), _subtype=subtype)
fp.close()
elif maintype == 'image':
fp = open(path, 'rb')
part = MIMEImage(fp.read(), _subtype=subtype)
fp.close()
elif maintype == 'audio':
fp = open(path, 'rb')
part = MIMEAudio(fp.read(), _subtype=subtype)
fp.close()
else:
fp = open(path, 'rb')
part = MIMEBase(maintype, subtype)
part.set_payload(fp.read())
fp.close()
# Encode the payload using Base64
encoders.encode_base64(part)
part.set_payload(part.get_payload().decode())

part.add_header('Content-Disposition', 'attachment', filename = 
path.split(os.sep)[-1])
self.attachments.append(part)  

def send_now(self, mail_from, mail_to, subject, multipart_subtype='mixed', 
host=None, port=25, auth=False, user="", passw=""):
msg = MIMEMultipart(multipart_subtype)
msg['Subject'] = subject
msg['From'] = mail_from
if type(mail_to) is list:
msg['To'] = ", ".join(mail_to)
else:
msg['To'] = mail_to

for b in self.body:
msg.attach(b)

for att in self.attachments:
msg.attach(att)

try:
mailserver = smtplib.SMTP(host, port)
#mailserver.set_debuglevel(1)
mailserver.ehlo() 
mailserver.starttls() 
mailserver.ehlo()
if auth:
mailserver.login(user, passw) 

mailserver.sendmail(mail_from, mail_to, msg.as_string())

mailserver.close()

return True
except Exception as e:
print(e)
return False

The database to attach is in the final.

The example:
s = SendMail()
s.add_body("test")
s.add_attach(os.path.abspath("test.db"))
s.send_now("t...@domain1.com", "t...@domain2.com", "test", 
host="smtp.domain1.com", port=25, auth=True, user="user", passw="pass")

[issue9295] test_close_open_print_buffered(test_file) sometimes crashes

[Hirokazu Yamamoto]

Hirokazu Yamamoto  added the comment:

> Does the following patch solve your issue?

I tried, but it still crashed. I could reproduce the crash by following
script. It crashed also on Python2.7, but it doesn't crash on Python3.
And when I used io.open() instead of builtin open(), it doesn't crash
even on Python2.x. (Probably because io.open implements buffer protocol
by itself)

//

import threading
import sys

if sys.version_info.major == 3:
xrange = range

def main():
size = 1024 * 1024 # large enough
f = open("__temp__.tmp", "w", size)
for _ in xrange(size):
f.write("c")
t1 = threading.Thread(target=f.close)
t2 = threading.Thread(target=f.close)
t1.start()
t2.start()
t1.join()
t2.join()

if __name__ == '__main__':
main()

//

I lied a bit on msg110655. close(2) is not used, that is actually
fclose(). I didn't notice the variable *close* was declared as
the parameter of fill_file_fields().

[issue2636] Regexp 2.7 (modifications to current re 2.2.2)

[Vlastimil Brom]

Vlastimil Brom  added the comment:

Thanks for the update;
Just a small observation regarding some character ranges and ignorecase, 
probably irrelevant, but a difference to the current re anyway:

>>> zero2z = 
>>> u"0123456789:;<=>?...@abcdefghijklmnopqrstuvwxyz[\]^_`abcdefghijklmnopqrstuvwxyz"

>>> re.findall("(?i)[X-d]", zero2z)
[]

>>> regex.findall("(?i)[X-d]", zero2z)
[u'A', u'B', u'C', u'D', u'X', u'Y', u'Z', u'[', u'\\', u']', u'^', u'_', u'`', 
u'a', u'b', u'c', u'd', u'x', u'y', u'z']
>>>


re.findall("(?i)[B-d]", zero2z)
[u'B', u'C', u'D', u'b', u'c', u'd']

regex.findall("(?i)[B-d]", zero2z)
[u'A', u'B', u'C', u'D', u'E', u'F', u'G', u'H', u'I', u'J', u'K', u'L', u'M', 
u'N', u'O', u'P', u'Q', u'R', u'S', u'T', u'U', u'V', u'W', u'X', u'Y', u'Z', 
u'[', u'\\', u']', u'^', u'_', u'`', u'a', u'b', u'c', u'd', u'e', u'f', u'g', 
u'h', u'i', u'j', u'k', u'l', u'm', u'n', u'o', u'p', u'q', u'r', u's', u't', 
u'u', u'v', u'w', u'x', u'y', u'z']

It seems, that the re module is building the character set using a case 
insensitive "alphabet" in some way.

I guess, the behaviour of re is buggy here, while regex is ok (tested on py 
2.7, Win XPp).

[issue1098749] Single-line option to pygettext.py

[Alexander Belopolsky]

Alexander Belopolsky  added the comment:

A rare example of a 5-year old patch that still applies with only a minor 
tweak.  This is probably a sign that pygettext itself has not been kept up to 
date.   In any case, I am attaching an updated patch which I did not test 
beyond running pygettext.py -h.  There was no response from OP to the patch 
review and from a brief look at the patch, it is not commit ready.

I am adding this as a dependency to meta-issue #7962 so that the fate of this 
patch and pygettext itself can be decided.

[issue4111] Add Systemtap/DTrace probes

[Alexander Belopolsky]

Alexander Belopolsky  added the comment:

If any RedHat/Fedora people are tuned in, can you give us an update on 
Systemtap/DTrace support in RedHat/Fedora python?  I understand that one of the 
main problems with bringing this upstream was the lack of uniformity between 
Apple and Sun approaches.  These days Apple and Sun(Oracle) are increasingly 
unfriendly to open source, so with a third solution available from RedHat, the 
choice seems obvious.

[issue9265] Incorrect name passed as arg[0] when shell=True and executable specified

[Narnie Harshoe]

Narnie Harshoe  added the comment:

I'm sorry, but the last lines in the interpreter reflect my code changes which 
seemed to not be sufficient, but it shows that just for this case at least, it 
corrects it and allows it to be run in /bin/bash shells (much of my shell code 
is bash since I'm linux only and this is usually available and I make use of 
c-like math or incrementors like $(( x++ )) in the shell code (I know, I know, 
I should make my code more portable such that it can run on /bin/sh, but I'm 
lazy).

[issue9265] Incorrect name passed as arg[0] when shell=True and executable specified

[Narnie Harshoe]

Narnie Harshoe  added the comment:

Hello,

I am impressed by the activity here. I am a new programmer and cutting my teeth 
with python. I wish I knew how to do a patch and write unit tests, but I'm just 
not there yet.

I can show a test case in this fashion where it fails.

First I prove that /bin/sh is /bin/sh (er, dash) and /bin/bash is /bin/bash. 
Then it can be seen that when executable is set as /bin/bash and there is a 
shell error, that it returns a shell error from /bin/sh, not from /bin/bash.

I see there are patches here that should fix it, but for those wanting to see 
the buggy code in action, here it is using the fact that echo was mistyped as 
echos to raise a shell error (but shell=True so it doesn't raise an OSError 
exception).
_

in shell terminal:
$ file /bin/bash
/bin/bash: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), 
dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped
$ file /bin/sh
/bin/sh: symbolic link to `dash'
$ file /bin/dash
/bin/dash: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), 
dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped

in python interactive interpreter

>>> shell = Popen('echos', shell=True, executable="/bin/bash", stdin=PIPE, 
>>> stderr=PIPE, stdout=PIPE)
>>> shell.communicate()
('', '/bin/sh: echos: command not found\n')
>>> shell = Popen('echos', shell=True, executable="/bin/bash", stdin=PIPE, 
>>> stderr=PIPE, stdout=PIPE)
>>> shell.communicate()
('', '/bin/bash: echos: command not found\n')

Thank you for working on this so quickly. This is truly an amazing community.

I don't understand why you say that. Why is f->f_fp already NULL while
close() still hasn't been called?

By the way, is it 2.6-specific or does it also happen on 2.7?

[Hirokazu Yamamoto]

Hirokazu Yamamoto  added the comment:

Hmm, correct me if following understanding is wrong somewhere...
1. File.close() is actually file_close(), and is calling close_the_file().
2. Returns immediately because local_fp == f->f_fp is already NULL.
   The return value is None.
3. sts is non-NULL, so PyMem_Free(f->f_setbuf) happens.
4. There is no system call for FILE object, so thread won't wait for close(2) 
completion.

Maybe can we fix this issue by the patch like this? I moved PyMem_Free
into close_the_file(), and called it only when close operation
succeeded.

[issue2813] No float formatting in PyString_FromFormat

[Jean Brouwers]

Jean Brouwers  added the comment:

Mark L,

No, I do not intend to take this issue further.  Rather the opposite, it should 
probably be paired down based on the recent comments.  Specifically, use 
PyOS_double_to_string, remove support for long double and perhaps more.

Also, the patches I created are more than 2 years old and will need to be 
updated against the current stringobject.c code.  There are quite a few changes 
in the 2.7 version of that file since early 2.6.

[issue9296] json module skipkeys handling changed exception types in 2.7

[Doug Hellmann]

New submission from Doug Hellmann :

Under Python 2.6 the json encoder raised a TypeError when it encountered 
dictionary keys that were not strings.  Under 2.7, that exception has changed 
to a ValueError, but the documentation still says it raises TypeError.  I'm not 
sure which is right, but TypeError seems like the correct exception.

[issue9295] test_close_open_print_buffered(test_file) sometimes crashes

[Antoine Pitrou]

Antoine Pitrou  added the comment:

The proposed resolution is wrong. As the comment says, there is a specific 
reason why f->fp is NULLed at this point.

It appears that maybe MSVCRT is not entirely thread-safe with respect to 
buffered file I/O. Perhaps the test can simply be disabled under Windows. Is 
test_close_open_print_buffered the only test that fails?

[issue2927] expose html.parser.unescape

[Reid Kleckner]

Reid Kleckner  added the comment:

It's using the old Python 2 unicode string literal syntax.

It also doesn't keep to 80 cols.

I'd also rather continue using a lazily initialized dict instead of catching a 
KeyError for '.

I also feel that with the changes to Unicode in py3k, the cp1252 stuff won't 
work as desired and should be cut.

===

Is anyone still interested in html.unescape or html.escape anyway?  Every web 
framework seems to have their own support routines already.  Otherwise I'd 
recommend close -> wontfix.

Thread 5384 entered close_the_file() and ran local_close() and allowed
another thread to run. Before this, fp->f_fp was set to NULL. Thread 5376
entered close_the_file() and see fp->f_fp is NULL, and returned immediately
and freed fp->f_setbuf. Interesting point is, thread 5384 was still running
close(2), so flush(2) called by this function touched this buffer and crashed.

thread(5376) func(file_close): leave

Thread 5384 entered close_the_file() and ran local_close() and allowed another 
thread to run. Before this, fp->f_fp was set to NULL. Thread 5376 entered 
close_the_file() and see fp->f_fp is NULL, and returned immediately and freed 
fp->f_setbuf. Interesting point is, thread 5384 was still running close(2), so 
flush(2) called by this function touched this buffer and crashed.

[issue9295] test_close_open_print_buffered(test_file) sometimes crashes

[Hirokazu Yamamoto]

New submission from Hirokazu Yamamoto :

I noticed test_close_open_print_buffered(test_file) sometimes crashes on 
release26-maint branch. This is most problamatic part in my python2.6 test 
survey on VC6 + Win2K.

Here is stacktrace.

_write_lk(int 6, const void * 0x00b49240, unsigned int 11) line 155 + 3 bytes
_write(int 6, const void * 0x00b49240, unsigned int 11) line 79 + 17 bytes

PyEval_EvalFrameEx(_frame * 0x00b33d50, int 131) line 2414
(snip)

Python crashes when MSVCRT touches internal buffer of file object via flush() 
in close().

I think this is multi-threading bug related to internal buffer of file object. 
I'll post more.

[issue9294] Dead code in Objects/object.c

[Antoine Pitrou]

New submission from Antoine Pitrou :

internal_print() is called from only one place, with the `nesting` argument 
wired to 0, therefore the following chunk of code in internal_print() never 
gets a chance to be executed:

if (nesting > 10) {
PyErr_SetString(PyExc_RuntimeError, "print recursion");
return -1;
}

[issue9293] Unsupported IO operations should raise UnsupportedOperation

[Antoine Pitrou]

New submission from Antoine Pitrou :

Some of them currently raise IOError. Fortunately, UnsupportedOperation 
inherits from IOError, which means compatibility can be preserved.

Contrast:
>>> open("LICENSE").write("bar")
Traceback (most recent call last):
  File "", line 1, in 
IOError: not writable

With:
>>> open("LICENSE", "rb").write(b"")
Traceback (most recent call last):
  File "", line 1, in 
io.UnsupportedOperation: write

Or:
>>> io.StringIO().fileno()
Traceback (most recent call last):
  File "", line 1, in 
io.UnsupportedOperation: fileno

Or, unfortunately:

>>> open("LICENSE", "rb", buffering=0).write(b"")
Traceback (most recent call last):
  File "", line 1, in 
ValueError: File not open for writing

[issue9292] Dead code in Modules/pyexpat.c

[Antoine Pitrou]

New submission from Antoine Pitrou :

There's some dead code in xmlparse_ParseFile() in Modules/pyexpat.c: the file 
pointer "fp" is always NULL, and as such the following code can never get 
entered into:

if (fp) {
bytes_read = fread(buf, sizeof(char), BUF_SIZE, fp);
if (bytes_read < 0) {
PyErr_SetFromErrno(PyExc_IOError);
return NULL;
}
}

There might be similar situations in other methods.

I suppose I sounded a bit like the Oracle of Delphi here. :)

I compiled with OPT="-O0 -g -funsigned-char" and stepped through the code 
(pre-patch).
With '<', np_bool is substituted for bp_bool (apparently in PyInit__struct).

np_bool correctly returns -1, so the problem does not occur.

[issue9291] mimetypes initialization fails on Windows because of non-Latin characters in registry

[Dmitry Jemerov]

New submission from Dmitry Jemerov :

On Windows, mimetypes initialization reads the list of MIME types from the 
Windows registry. It assumes that all characters are Latin-1 encoded, and fails 
when it's not the case, with the following exception:

Traceback (most recent call last):
  File "mttest.py", line 3, in 
mimetypes.init()
  File "c:\Python27\lib\mimetypes.py", line 355, in init
db.read_windows_registry()
  File "c:\Python27\lib\mimetypes.py", line 260, in read_windows_registry
for ctype in enum_types(mimedb):
  File "c:\Python27\lib\mimetypes.py", line 250, in enum_types
ctype = ctype.encode(default_encoding) # omit in 3.x!
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe0 in position 0: ordinal 
not in range(128)

This can be reproduced, for example, on a Russian Windows XP installation which 
has QuickTime installed (QuickTime creates the non-Latin entries in the 
registry). The following line causes the exception to happen:

import mimetypes; mimetypes.init()
