Many runner fans were ecstatic to hear about these particular Air max's making a return.
Many runner fans were ecstatic to hear about these particular Air max's making a return. The Nike Air Max 90 is a prized colorway of a classic sneaker, so it only makes sense that its return would create serious buzz. Nike’s Blue Slate Air Max 95 has made a triumphant return to retail shelves this season from Nike Sportswear. The nickname “Slate” comes from entirely the colorway, which is White/New Green-Blue Slate-Black. The retro running shoe features white uppers and a black outsole. Blue accents are seen on areas such as the lace holders and mid-panel. While these retro running shoes were originally released back in 2005 the Air Max 95 “Slates” the new released version is different than the last time we saw these, as black has replaced navy on the top layer, and the lower two rows are the same shade of blue, instead of being slightly different. The Air Flight Family is pleased to welcome a new member to the family, the Air Max 95 basketball shoe. The Falcon appears as a younger generation of the Nike Air Flight 89. The layout of the paneling throughout the upper screams out Air Flight 89, and if you give it a good look you’ll also notice some elements taken from the Air Flight Lite. If you can’t see the Air Flight Lite in the upper you always have the “Flight F” logo on the tongue which is the same as that used on the Flight Lite. To start things off the Air Flight Falcon basketball shoe features a white/metallic silver base constructed from smooth leather and tumbled leather. From there a few hits of black and red were added in, most notably on the glossy Swoosh, Flight tongue tag, and on the Air Jordan IV sole unit, with black corduroy used on the inner lining. Breathing life into the sneakers and giving some accent coloring is red trim throughout the entire upper.

Threading with Socket Server
Hello all, I am writing a Windows service that needs to 1) Act as a server (TCP), and write to a shelve file, and 2) Read that same shelve file every x number of seconds. My thought is to create 2 separate classes (1 for the socket server and writing to the shelve file, and another to read the file and perform other requested actions) - however, I need to make sure they are both running concurrently. I'm sure threading is involved, but my experience with it has been minimal, so any help to steer me in the right direction is greatly appreciated. -- http://mail.python.org/mailman/listinfo/python-list

Special logging module needed
Hi All, We have a special problem that needs to be addressed. We need to have a database of log messages. These messages are not simple strings - they are data structures. The log messages are assigned to various objects. Objects can be identified with simple object identifiers (strings). We have about 10 million objects. Most of them only have one or two log messages assigned. Some of them (about 1M objects) will have 10 log messages appended each day. Fewer objects (100K) will have log messages appended even more frequently. Requirements: * The database is mostly write-only. In most of the time, we will be adding messages continuously, and we won't read them back. * Appending new messages should be fast. At least 100 messages / second. * High availability - clients must be able to add new log messages and read back old messages anytime. The service must not stop. * Database is huge. We want to preserve data for one or two years and possibly it will grow to 1TB or something. * We should be able to drop older data (e.g. log messages appended more than 2 years ago) without trouble. * We need to implement incremental backups. For example, we could have a separate database file for every day in the current month, then database files for previous months etc. The main point is that we should be able to make backup copies incrementally, and the logging service should be available at the same time. (It is not curical to have an up-to-date backup from the current day, but we want to backup everything that happened more than a day ago). * Reading back log messages will happen rarely. Average would be 5 times in every minute, and usually only for a given date range. (for example, all messages from 2010 May) But then it should be relatively fast. Even with a 1TB database, we should be able to fulfill such a request within one second. What we where doing until now, is that we have used a directory structure. Every object had a separate CSV file assigned, and new messages where appended into those CSV files. We thought that appending new messages will be fast (fopen + fwrite should be fast) and reading them back sould also be fast. But now we are suffering from these problems: * We have millions of files on disk. Very hard to synchronize them, make incremental backup copies. It is just too slow. * Sometimes the OS cannot handle requests fast enough. There are too many (at least 5million) files on the file system and they are very fragmented. In some cases it takes 10 seconds or more to open a log file for appending. CPU goes up to 100% apparently when the OS tries to open the log file. (dirhash mem already increased to 1GB but it's still not good enough.) I was thinking about using a regular SQL database, but it has problems: * Not easy to do incremental backups * Not that easy to remove old data (e.g. cannot delete 100GB data with SQL without big slowdon) * With a btree index and some 100 million rows already in a table, appending messages may not be fast enough (because of heavy reindexing). I may be wrong about this. I was also thinking about storing data in a gdbm database. One file for each month storing at most 100 log messages for every key value. Then one file for each day in the current month, storing one message for each key value. Incremental backup would be easy, and reading back old messages would be fast enough (just need to do a few hash lookups). However, implementing a high availability service around this is not that easy. I'm just wondering if there is an open source solution for my problem that I don't know of.

readline module (python: symbol 'tgetnum': can't resolve symbol)

Re: Threading with Socket Server
I'm not sure to understand what you want. Is it your server process that will read the shelve file ? You may give more informations about your problem, but i can give you some hints. In order to create a TCP server, you can use SocketServer which is in the builtin library (http://docs.python.org/library/socketserver.html). I'm not sure about how shelve manage concurrency, but in my opinion, you'll need to create a single process or thread which manage read and write operation in order to avoiding race conditions.

Re: Threading with Socket Server
The server portion of the program will typically be writing to the shelve file (there may be a few cases in which I will need it to read), and the other part of the program will read it. Basically, I want the following to be able to both go on at the same time: 1) Server portion waits for connections, and upon connection writes data received to shelve file and 2) Continuously polls shelve file every x seconds and checks for new entries. I had given thought to the potential of a race condition as you mentioned, but am not sure of how to safely allow each portion of the program to read/write. -- http://mail.python.org/mailman/listinfo/python-list

to do this?

One file for each month storing at most 100 log messages for every key value. Then one file for each day in the current month, storing one message for each key value. Incremental backup would be easy, and reading back old messages would be fast enough (just need to do a few hash lookups). However, implementing a high availability service around this is not that easy. I think a slight variation of this sounds like a good bet for you. But when you open a database, create a temporary copy, and when you close the database, rename it back to its original name. Then your backups should be able to easily get a self-consistent (if not up to the millisecond) snapshot. Or did you have some other problem in mind for the gdbm version? BTW, avoid huge directories of course, especially if you don't have hashed or btree directories. One way is to come up with a longish hash key (sha?), and use a trie-like structure in the filesystem on fibonnaci-length chunks of the hash keys becoming directories and subdirectories. -- http://mail.python.org/mailman/listinfo/python-list

The cmp argument of sort doesn't.

[issue11633] regression: print buffers output when end=''
STINNER Victor victor.stin...@haypocalc.com added the comment:
amaury When python is run from a console, sys.stdout is line buffered.
amaury sys.stdout.write() flushes if there is a carriage return.
amaury No need to change anything here.
Anatoly would like a flush after all calls to print().
print() could call file.flush() if file.isatty(), *after* the multiple
calls to file.write().
I vote +0 to change print(), call sys.stdout.flush(), if:
- file option is not used (and so, sys.stdout is used)
- sys.stdout is a TTY
- end option is used (fast heuristic to check if print will write a newline or
not, a better one whould be to check if end contains a newline character or
not, but we had to check for \n and/or \r, for a little gain)
But I don't want to change print() for print(text, file=file), because it would
make Python slower and print(... file=file) is not used to an interactive
prompt or to display informations to the user.
Behavior is same when pasting into interactive interpreter ...
I presume interpreter flushes before or after printing next prompt.
Did you wrote all commands on the same line? Python does change stdout buffer
in interactive mode:
if (Py_UnbufferedStdioFlag) {
#ifdef HAVE_SETVBUF
setvbuf(stdin, (char *)NULL, _IONBF, BUFSIZ);
setvbuf(stdout, (char *)NULL, _IONBF, BUFSIZ);
setvbuf(stderr, (char *)NULL, _IONBF, BUFSIZ);
#else /* !HAVE_SETVBUF */
setbuf(stdin, (char *)NULL);
setbuf(stdout, (char *)NULL);
setbuf(stderr, (char *)NULL);
#endif /* !HAVE_SETVBUF */
}
else if (Py_InteractiveFlag) {
#ifdef MS_WINDOWS
/* Doesn't have to have line-buffered -- use unbuffered */
/* Any set[v]buf(stdin, ...) screws up Tkinter :-( */
setvbuf(stdout, (char *)NULL, _IONBF, BUFSIZ);
#else /* !MS_WINDOWS */
#ifdef HAVE_SETVBUF
setvbuf(stdin, (char *)NULL, _IOLBF, BUFSIZ);
setvbuf(stdout, (char *)NULL, _IOLBF, BUFSIZ);
#endif /* HAVE_SETVBUF */
#endif /* !MS_WINDOWS */
/* Leave stderr alone - it should be unbuffered anyway. */
}
#ifdef __VMS
else {
setvbuf (stdout, (char *)NULL, _IOLBF, BUFSIZ);
}
#endif /* __VMS */
(it doesn't check if stdout is a TTY or not, but I don't think that it is very
useful to use the interactive mode outside a TTY)
I have always experienced and expected Python's print to screen
to be immediately visible. I thought that was pretty standard
in other languages with a print-to-screen separate from
general file-write.
Did you try Perl, Ruby, bash and other languages? I know that at least the C
language requires an explicit call to fflush(stdout). I always used that.
Terry, IDLE is completely different, its sys.stdout completely
bypasses the new io stack, and there is no buffering...
As I wrote: unbuffered mode is not implemented for TextIOWrapper. So even
with python3 -u, sys.stdout.write(abc) doesn't flush immediatly into the
underlying FileIO.

New submission from Gunnar Aastrand Grimnes gromg...@gmail.com:
The startElementNS method in the XMLGenerator ignores the encoding set.
it does:
self._out.write(' xmlns:%s=%s' % (prefix, uri))
whereas it should have done:
self._write(' xmlns:%s=%s' % (prefix, uri))
Issue 938076 was similar to this, but for a different method.

[issue11650] CTRL-Z causes interpreter exit
Charles-Francois Natali neolo...@free.fr added the comment:
In that case, it's likely due to the way OS-X handles interrupted syscalls.
Under Linux, getchar and friends (actually read with default SA_RESTART) won't
return EINTR on (SIGSTOP|SIGTSTP)/SIGCONT.
Under OS-X, it seems that e.g. getchar (read) does return EOF with errno set to
EINTR, in which case the interactive interpreter will exit, if errno is not
checked.
Out of curiosity, could you try the C snippet:
#include stdio.h
int main(int argc, char *argv[])
{
int c;
if ((c = getchar()) == EOF) {
perror(getchar);
}
return 0;
}
And interrupt it with CTRL-Z ?

It seems to be some kind of urban legend at this point. A merge won't magically break all C files and prevent Python from compiling. Especially if no C files were touched in the first place! If you are confident that you didn't introduce any issue then just commit your merge and push (or run the tests which are relevant to your initial commit). Oh, and again, if some tests are slow on your system, then *please* open issues about them (and/or investigate *why* they are slow).

[issue11651] Improve test targets in Makefile
Barry A. Warsaw ba...@python.org added the comment: On Mar 23, 2011, at 04:22 PM, Antoine Pitrou wrote: What does brown paper bag way mean? It seems to be some kind of urban legend at this point. A merge won't magically break all C files and prevent Python from compiling. Especially if no C files were touched in the first place! This whole thread came up originally because some folks wanted a smoke test while resolving the merge race window. If you are confident that you didn't introduce any issue then just commit your merge and push (or run the tests which are relevant to your initial commit). A smoke test addresses the confidence issue, while not introducing a longer race window to run the full test suite. Oh, and again, if some tests are slow on your system, then *please* open issues about them (and/or investigate *why* they are slow). That's much better than ignoring/blacklisting them.

[issue11653] Problems with some tests using -j2
New submission from Skip Montanaro s...@pobox.com: At Antoine's behest, I tried running ./python.exe -m test -j2 in my cpython sandbox and saw several test case failures which didn't appear when I executed a simple make test He suggested I add the -W flag and try again. I did, but I don't see any difference in the output, so either I'm still doing something wrong or the -W flag is somehow mishandled. As far as I can tell the failing tests were not re-run in verbose mode. script command output attached. I ran these tests on Mac OS X Leopard (10.5.8).

[issue11651] Improve test targets in Makefile
Ross Lagerwall rosslagerw...@gmail.com added the comment: The patch seems to work. I agree that quicktest and memtest should be removed as well as the duplicate test. The only thing I would change is to create the number of jobs to be double the cpu count - I think this works quicker. I don't think the length of testing is so bad on my 3 year old core 2 duo it takes 2:40 to run: EXTRATESTOPTS=-j4 time make test -- nosy: +rosslagerwall ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11651 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
