[issue40053] Document the behavior that no interplotation is applied when no *args are passed in for logging statements

[issue40053] Document the behavior that no interplotation is applied when no *args are passed in for logging statements
New submission from Nan Hua :
As I see, Python's logging module's implementation has a nice property that,
when no additional args are passed in, the msg (first argument) will be
directly printed.
For example, logging.error('abc %s') can be handled peacefully with printing
"ERROR:root:abc %s" in the log.
However, the logging's documentation only said the followings:
"The msg is the message format string, and the args are the arguments which are
merged into msg using the string formatting operator."
>From what I see, this implementation (seems the case for both Python2 and
>Python3) has many benefits: saving CPU resources, safe handling pre-formated
>string, etc. More importantly, it also de-facto allows using the convenient
>f-string in logging statement, e.g.
logging.error(f'Started at {start_time}, finished at {finish_time}'
f' by user {user}')
can run correctly and smoothly even with user containing %s inside.
In summary, I hope this de-facto actual behavior can be officially endorsed,
with wordings like,
"When *args is empty, i.e. no additional positional arguments passed in, the
msg be of any string (no need to be a format string) and will be directly used
as is without interpolation."
What do you think? Thank you a lot!

[issue30367] Cannot build CPython3.6 with module “testcapimodule” statically
New submission from Nan Zhang:

I am trying to build CPython3.6 from GitHub statically with the Documentation
below:
https://wiki.python.org/moin/BuildStatically
Changed *shared* to *static*
And only uncommented the module "testcapimodule" in Modules/Setup file:
_testcapi _testcapimodule.c # Python C API test module
And ran with 'make LINKFORSHARED=" "'
However I got errors that:
gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3
-Wall -Wstrict-prototypes-std=c99 -Wextra -Wno-unused-result
-Wno-unused-parameter -Wno-missing-field-initializers -I. -I./Include
-DPy_BUILD_CORE -c ./Modules/_testcapimodule.c -o Modules/_testcapimodule.o
./Modules/_testcapimodule.c: In function ‘test_datetime_capi’:
./Modules/_testcapimodule.c:2191:9: error: ‘PyDateTimeAPI’ undeclared
(first use in this function)
if (PyDateTimeAPI) {

./Modules/_testcapimodule.c:2191:9: note: each undeclared identifier is

PyDateTime_IMPORT;
^
./Modules/_testcapimodule.c:2208:1: warning: control reaches end of
non-void function [-Wreturn-type]
}
^
make: *** [Modules/_testcapimodule.o] Error 1
But when I build Cpython3.6 with *shared*, it can succeed.

Django runs inside apache. It's kinda weird to have an apache process
restart itself and expect it to return to the caller.
If the init script does like mine, reload executes apachectl -k
graceful What that instructs apache to do is to restart, but only
kill the process(es) when there are no more connections. So apache is
waiting for your connection to close, but you are inside an HTTP request
waiting for apache to restart. So you have a race condition here.
It's not advisable to have apache kill itself and expect it to send a
status back to you telling you it's dead.
See the apache docs[1] for a better explanation.
http://httpd.apache.org/docs/2.0/stopping.html#graceful
Ah, I'd been told that there would be no conflict, and that this was
just reloading the configuration, not restarting Apache.
I do need the web app to instruct Apache to reload because just before
this it's creating new VirtualHosts that need to be recognized. Is
there a better way to do this (e.g. to say start doing this once I'm
finished)?
I'm getting a status code and output from the call before the Django
script stops executing... Is there a way to stop waiting for the
process to complete once I have those?

Is there a way to stop waiting for the process to complete once I have those? I have a wireless router with a built in web server. Sometimes it needs to reload it's config. Basically what it's doing is rebooting the entire router (I can see this if I'm actuall watching the router). All it is doing, I'm pretty sure, is calling some program that forks another process and then exits the main program. The forked process then reboots the router. Meanwhile before that happens the web server sends a response. Basically in the response it sends an HTTP Refresh with x number of seconds. Presumably x is longer than the time it requires for the router to reboot. The router reboots, the browser refreshes and viola. You probably need to so something similar in that your request calls a program that forks off and restarts apaches. It should probably not do so immediately so that your request has time to send a response with a refresh header (but that shouldn't take long). After a second or so, apache will have restarted and the browser will have refreshed. so (untested): def reload(request): subprocess.call(['my_apache_reloader']) # this should fork and exit response = HttpResponse() response['Refresh']='3; url=%s' % reverse(home) # chk back in 3 secs return response BTW There is a Django mailing list where this might be more appropriate to discuss. -a Sadly, questions about subprocess spawning on the Django lists seem to get referred back to the Python lists when they get an answer at all. You've been very helpful, though, so thank you. I think I'll have to mark in the database when the server needs restarting, and run a cron job to check that and reload Apache from a non-Apache process. It will mean delayed creation of the Virtual Hosts and no immediate feedback to indicate success or failure, but it doesn't look like there's much alternative. -- http://mail.python.org/mailman/listinfo/python-list

newbie question
Hello, I just started to use Python. I wrote the following code and expected 'main' would be called. def main(): print hello main But I was wrong. I have to use 'main()' to invoke main. The python interpreter does not give any warnings for the above code. Is there any way/tool to easily detect this kind of errors ? Thanks ! -- http://mail.python.org/mailman/listinfo/python-list
