Re: [web2py] Re: Web2py's included connection pooling VS external pooling software
Actually I was referring to max-procs parameter of the fastcgi server that
is setup in lighttpd virtual host configuration. I don't know if you mean
that. In my virtual host configuration, I setup the fastcgi server like
this:
fastcgi.server = (
".fcgi" => ("localhost" => (
"check-local" => "disable",
"max-procs" => 2,
"socket" => "/var/tmp/lighttpd/diarioprimicia.sock",
"bin-path" => "/var/www/diarioprimicia/diarioprimicia.fcgi")
)
)
Is that what you mean by fastcgi server parameters?
Yesterday I changed from "fcgi_fork" to "fcgi" (still using flup), and I
set "max-procs" to 2 (like example above), and then used pgrep to check for
processes, and now I see 2 as expected. I also noticed a better usage of
ram as you said!
I must ask: ¿is there an obvious reason not to use flup? I have to say that
I'm no "server administrator guru". I just started using web2py, everything
scaled quick, and after some time, step by step, I ended up where I'm now,
with linode with ubuntu server, running web2py on production with several
sites.. I already have scripts that I can easily run to setup a full site:
as I said, the app installed in every site is the same, so my script takes
care of creating the folders, the database, cloning repository, creating
virtual host configuration, fcgi handler, etc.
So now if I want to switch to something else, I must have a very good
reason because I would have to rewrite the scripts and migrate all the
current sites. So that's why I'm asking if there is an obvious reason to
stop using flup (I've read some place that the author has discontinuated it
but I'm not shure).
I also read good stuff about nginx, some say that I should change from
lighttpd to nging, but everythin is working so fine that I'm not shure if I
should change anything :P
In the other hand, in relation to the database connections and pooling
mechanism, I posta question in the mailing list of pgbouncer, to clarify a
couple of doubts I had specifically about pgbouncer. Here is the full
conversation, if it helps anybody:
http://comments.gmane.org/gmane.comp.db.postgresql.pgbouncer.general/1168
Just to tell, now I have pgbouncer running on transaction pooling mode
(web2py's pooling mechanism is disabled, that is, DAL with pool_size=0). I
started lowering the pool_size of one of the database/user pairs (that is,
lowering the pool_size of one of the sites), and in turn out to one point
where I couldn't access the website, my browser kept "waiting for site".
That is what I was looking for, so for the moment I'm going to use this
configuration.
Notice that in pgbouncer the pool_size is asigned to the database/user
pair, so regardless of the number of "max-procs" in fastcgi server, if
every process connects with DAL(...) to the same database/user, all the
fastcgi processes will "share" the pool (I mean, it's transparent to
pgbouncer).
Thanks again and sorry about the extense emails. I'm working on that :P

Re: [web2py] Re: Web2py's included connection pooling VS external pooling software
why not flup?
- not event based. Event based servers are usually more responsive under
load.
- seems pretty unmantained.
- misses some tuning options.
max-procs in lighttpd configuration:
- leave it to 1
- work with the following options in your script:
WSGIServer(application, minSpare=1, maxSpare=5, maxChildren=50,
maxRequests=0)
explanation from flup code:
"""
A preforked server model conceptually similar to Apache httpd(2). At
any given time, ensures there are at least minSpare children ready to
process new requests (up to a maximum of maxChildren children total).
If the number of idle children is ever above maxSpare, the extra
children are killed.
If maxRequests is positive, each child will only handle that many
requests in its lifetime before exiting.

[web2py] web2py and pylint
pylint checks fail on web2py controllers and models because web2py automatically imports several modules/classes/variables at runtime. I assume this is a known issue and there is no workaround? -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

[web2py] Re: A newbe needs help
Hello Paul, Where are you installing this from? You are using a version that is 3 years old. You should download and unzip the version from the web2py.com web site. The version issue may or may not be related to the cache problem.

[web2py] Re: Modules and controllers running in processes - global variables
Because requests are handled by threads, the way to do this may be to use the current object. Note that you should replace "processes" with "threads" in your question. Most web2py execution environments are multi-threaded not not-multiprocess. You set your global variables in one of the code bodies executed at each request; example the default model db.py, and assign them to the current object. This is often done for passing to modules web2py global variables like DAL instances. Therefore the documentation in the book concentrates on solving this problem http://www.web2py.com/books/default/chapter/29/04/the-core#Accessing-the-API-from-Python-modules but the idea is extendable to all globals. Then in each *function* in a module, you retrieve them. Don't retrieve them in the lexical global scope of the module file (i.e. outside a function body) because that code is not run in the thread you are interested in (the thread in which your module function is running).

Can you show some code (i.e, both some module code and how you are importing/accessing the objects from the controller)?

[web2py] Re: How to upload web2py code to git
Are you trying to do this via the web2py admin interface, is that what you mean? What type of web2py installation do you have? (did you clone github, a "source" installation) The git integration built in to the admin app worked last time I used it as long as the python git modules are available, but most of the time I use git in a shell.
