If there is any example of what you changed to your python program itself,

Yeah, I did that for the Yosemite Project:
https://github.com/Rosuav/Yosemite
The main program is Python, but all the systemd code comes from a Pike
script that creates a bash script that creates the systemd file. Yes,
that's a little convoluted... Here's the relevant shell script part,
in case you don't want to dig it out of auth.pike:
#!/bin/bash
[ $1 = install ] [ -d /etc/systemd/system ] {
echo [Unit]
Description=Yosemite Project
[Service]
# The user, path, and X display are derived at installation time
# from the attributes of the yos script. Reinstall to reset them.
Environment=DISPLAY=$DISPLAY
User=`stat -c %u $0`
ExecStart=`readlink -e $0`
# If the network isn't available yet, restart until it is.
Restart=on-failure
RestartSec=10
[Install]
WantedBy=multi-user.target
/etc/systemd/system/yos.service
# Note that some of this will fail if systemd is installed
# but isn't the default init system. In that case, well, you
# can't use this method of autostarting. TODO: Provide some
# other ways to autostart (eg for Upstart and/or sysvinit).
systemctl --system daemon-reload
systemctl enable yos.service
echo Installed as yos.service.
systemctl start yos.service
exit
}
# ... blah blah various setup
python Yosemite.py
This has some complications that you probably don't need, like that
the owner of the script should become the user that runs it (chances
are you can hard-code this, or run it as root and have it drop
privileges itself, or something), and it needs to restart on failure,
as it has to establish an sshfs mount before starting the main
program. But it's a start.
Note the three commands just before the script exits. Unlike sysvinit
and upstart, systemd needs to be told to reload service files, and
then you need to enable the service before it'll run on startup (and I
like to start it immediately, to see that it's working properly). Took
me a few hang-ups to figure that part out. Fortunately systemd can
notice and give a warning if you change files and don't daemon-reload
it; I'm not sure why it can't simply reload automatically (AIUI
Upstart uses inotify on /etc/init - no idea why systemd can't do the
same).

Why command os.popen works in python interactive mode but not in script debugger mode?
Can anyone give me hint or reason why same command behaves differently in
debugger mode from interactive mode:
From interactive mode:
import os
p = os.popen('date')
p.read()
'Thu Sep 11 11:18:07 PDT 2014\n'
But from debugger mode in a script:
import os
(Pdb) p = os.popen('date')
*** SyntaxError: SyntaxError('invalid syntax', ('string', 1, 1, =
os.popen('date')))
Can anyone help me why there is syntax here?

This is actually a command to the debugger. You say p
some_expression and it prints out the value of some_expression.
https://docs.python.org/2/library/pdb.html#debugger-commands
Commands that the debugger doesn’t recognize are assumed to be Python
statements and are executed in the context of the program being
debugged. Python statements can also be prefixed with an exclamation
point (!).
So try this:
!p = os.popen('date')

Eric V. Smith added the comment: I'm not particularly wild about the .precision syntax either, but I think the feature is generally useful. Adding bytes.__format__ is exactly what special output for bytes _is_, as far as format() is concerned. Another option would be to invent a new format specification for bytes. There's no reason it needs to follow the same syntax as for str, int, etc., except for ease of remembering the syntax, and some code reuse. For example, although it's insane, you could do: format(b'abcdwxyz', 'use_spaces,grouping=4,add_prefix') - '0x61626364 0x7778797a' -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22385 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

As per the recent discussion on python-ideas, the point where that is most useful is in debugging output. However, rather than a new method on bytes/bytearray/memoryview for this, I instead suggest it would be appropriate to extend the default handling of the x and X format characters to accept arbitrary bytes-like objects. The processing of these characters would be as follows: x: display a-f as lowercase digits X: display A-F as uppercase digits #: includes 0x prefix .precision: chunks output, placing a space after every precision bytes ,: uses a comma as the separator, rather than a space Hmm, but those would then work for str.format() as well, right ? Since x and X are already used to convert numbers to hex representation, opening these up for bytes sounds like it could easily mask TypeErrors for cases where you really want an integer to be formatted as hex and not bytes. -- nosy: +lemburg ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9951 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13968] Support recursive globs
Serhiy Storchaka added the comment:
Thank you Victor. The test was failed also when run it directly, omitting the
test.regrtest module (which run a test inside temporary directory):
./python Lib/test/test_glob.py
Now it is fixed.
However perhaps we should consider as a bug if a test ran by regrtest doesn't
clean created files or directories ('noodly2', '@test_23056_tmp-\udcff.py', and
'__pycache__' are created by some previous tests).

william tonkin added the comment: sqlite3 allows a connection to be built from an apsw.Connection(). Using an apsw.Connection() to build an sqlite3.connect() implies that the underlying sqlite database engine will have extended error codes turned on (the default if for them to be turned off.) The problem is that Modules/_sqlite/util.c:_pysqlite_seterror() is not extended error code aware. In particular, the extended error code SQLITE_CONSTRAINT_CHECK will not be recognized as a kind of constraint violation and will fall into the default: arm of the case statement. This will result in raising the exception DatabaseError when the correct exception to raise is IntegrityError. One simple solution would be to convert the extended error code back to the base error code, that is: errorcode = 0xffu % sqlite3_errcode(db); -- status: closed - open type: - behavior ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22382 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22391] MSILIB truncates last character in summary information stream
New submission from Kevin Phillips:
I recently exploited a subtle bug with the msilib module's GetProperty method
on the SummaryInformation class. When retrieving string-typed properties from
the stream the last character in the string gets truncated, replaced by a
null-byte.
I am using Python v3.2.5 64bit on Windows 7, and I've managed to reproduce the
error with the following code snippet:
filename = sample.msp
patch_database = msilib.OpenDatabase(filename, msilib.MSIDBOPEN_READONLY |
msilib.MSIDBOPEN_PATCHFILE)
summary_info = patch_database.GetSummaryInformation(20)
print (summary_info.GetProperty(msilib.PID_REVNUMBER))
The PID_REVNUMBER returns the patch-GUID for the Windows Installer patch file.
In this example the GUID is returned properly however the character string is
supposed to be delimited by curly braces - { }. Examination of the returned
byte array shows that the leading curly brace is included by the final curly
brace is not. Closer examination also shows that the last character in the byte
array is \x00.
While it is possible, in this situation, to circumvent the bug by simply
removing the trailing bytes and replacing them with a closing curly brace, this
may not be so easy to work around for general character strings if the last
character in the sequence is not static. As such I'd highly recommend fixing
this in the source for the msilib module.

I left the decision to English speakers. Also, you said that one of the re module's messages was better, but didn't say which! Did you mean this one? re:expected bytes, bytearray, or an object with the buffer interface, str found regex: expected bytes instance, str found Both are not good. re variant is too verbose, but it is more correct.

[issue22391] MSILIB truncates last character in summary information stream
Kevin Phillips added the comment:
I should mention that I did discover some source code on GitHub, presumably for
this wrapper module, and I believe I found a few questionable parts in the
logic for this library that may help explain the cause of this problem:
https://github.com/python-git/python/blob/master/PC/_msi.c
Here are some snippets from the summary_getproperty function that may help:
char sbuf[1000];
char *sval = sbuf;
DWORD ssize = sizeof(sval);
First, here, I believe the ssize value is not going to be initialized as one
would expect at first glance. Since sval is a pointer and sizeof() returns the
size of it's parameter, in this case a pointer, ssize will represent the
pointer size on the target platform. In this case, on a 64bit OS, it's likely
going to be set to 8, which I suspect the expected value for ssize is going to
be 1000 - the size of the static array sbuff.
status = MsiSummaryInfoGetProperty(si-h, field, type, ival,
fval, sval, ssize);
if (status == ERROR_MORE_DATA) {
sval = malloc(ssize);
status = MsiSummaryInfoGetProperty(si-h, field, type, ival,
fval, sval, ssize);
}
Now, in this snippet it tries to load the string value from the file, and if
the input buffer is not of sufficient size it reallocates the pointer to an
appropriate size. Given the fact that ssize is probably initialized to 8 (or
less) it is pretty safe to assume the first call to MsiSummaryInfoGetProperty
changes this value to the length of the data stored in the file. Closer
examination of the documentation for this Windows API function reveals that in
this case ssize will be set to the number of characters required 'not including
the terminating null character'.
(http://msdn.microsoft.com/en-us/library/aa370409(v=vs.85).aspx)
result = PyString_FromStringAndSize(sval, ssize);
Then finally I noticed this function call. I suspect the problem may lie here.
I'm not too familiar with the Python SDK but it sounds like when using Unicode
strings - as all string are in Python 3 - you are supposed to use
PyUnicode_FromStringAndSize instead. So perhaps there might be something
getting lost in the translation, either via the use of this function or perhaps
subsequent marshalling of the string object into the Python runtime, due to the
encoding changes... not sure. It could be something as simple as one of the
function calls used therein assume that the 'size' count includes a null-byte
while others don't. It's hard to say without digging into the libs some more.
I hope this helps.

It would also be prone to race conditions. All in all it sounds like a bad idea. I still think it should be asked for explicitly.

There's no reason to accept such invalid escapes. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22362 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue22299] resolve() on Windows makes some pathological paths unusable
Steve Dower added the comment: Another alternative is to always leave the prefix there after calling resolve() (as opposed to the current behaviour which is to always remove it). If the Win32 API says that the path should include the prefix, then it should. There's no reliable way for a developer to decide that an arbitrary path should include the prefix other than by resolving it. I still like the idea of a format character to omit the prefix, as that correctly implies that the only reason you should remove it is for displaying to the user. Alternatively, a .without_prefix property seems like a safer route than requiring the user to add it. Long paths are the only time you may want to add it, but even that doesn't guarantee that the path will work. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22299 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
