deployment problems with apache + starman
by Assaf Gordon 09 Nov '11

09 Nov '11

Hello, I'm having problems deploying a simple dancer app with Apache+Starman. Even using the most basic setup doesn't seem to work properly - the "request.uri_for()" returns "http://localhost:3000" instead of the virtual server name. I tried following the varied instructions in Dancer::Deployment, but that are just too many options, or perhaps I don't understand how the different parts connect. What I did is: ## 1. Create a new app $ dancer -a foo $ cd foo ## 2. Start the server with Starman $ plackup -s Starman -l 127.0.0.1:3000 ./bin/app.pl ## In Apache, my configuration is; <VirtualHost *:80> ServerName xxxx.cshl.edu ServerAlias xxxx ProxyPass / http://localhost:3000/ ProxyPassReverse / http://localhost:3000/ </VirtualHost> That's it, nothing more, nothing less. I can see the main Dancer website stub ("Perl is Dancing" etc.), but every link inside the HTML page (e.g. the CSS file) points to "http://localhost:3000" instead of "http://xxxx.cshl.edu" - so none of the links is working. Any suggestion will be highly appreciated, Thanks, -assaf.

unusual logging error
by Matt Williams 06 Nov '11

06 Nov '11

I'm using ubic to manage by starman daemon and cannot seem to get my app to log to a file. I am trying to log to /var/log/internal-api.log and have set the permissions to 777 for troubleshooting purposes. Manual testing on the command line verifies this odd behavior: plackup -E production -s Starman --workers 5 -p 5000 -a bin/app.pl An 'strace -fv' of the above command results in the following snippet: stat64("/var/log", {st_dev=makedev(252, 0), st_ino=3670214, st_mode=S_IFDIR|0755, st_nlink=14, st_uid=0, st_gid=0, st_blksize=4096, st_blocks=8, st_size=4096, st_atime=2011/11/03-09:41:41, st_mtime=2011/11/03-09:38:12, st_ctime=2011/11/03-09:38:12}) = 0 open("/var/log/internal-api.log", O_WRONLY|O_CREAT|O_APPEND|O_LARGEFILE, 0666) = 5 _llseek(5, 0, [0], SEEK_END) = 0 ioctl(5, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfdcba68) = -1 ENOTTY (Inappropriate ioctl for device) _llseek(5, 0, [0], SEEK_CUR) = 0 *Note the Inappropriate ioctl for device Following is my production.yml file. # only log warning and error messsages log: 'warning' # log message to a file in logs/ logger: 'file' log_path: '/var/log' log_file: 'internal-api.log' # don't consider warnings critical warnings: 0 # hide errors show_errors: 0 # cache route resolution for maximum performance route_cache: 1 Any ideas? Thanks, Matt

Dancer::MIME return value
by thecrux＠gmail.com 02 Nov '11

02 Nov '11

Hi. I had noticed that Dancer/MIME.pm (and also Dancer/Core/MIME.pm in Dancer2) return 42 https://github.com/sukria/Dancer/blob/devel/lib/Dancer/MIME.pm#L67 This is wrong, because generate warning $ perl -wce '42' Useless use of a constant (42) in void context at -e line 1. -e syntax OK Also, with `use warnings FATAL => 'all'` (default for Moo) returned error $ perl -c -Ilib lib/Dancer/Core/MIME.pm ; echo $? Useless use of a constant (42) in void context at lib/Dancer/Core/MIME.pm line 77. 255 -- Vladimir Lettiev aka crux ✉ theCrux(a)gmail.com

trouble with routes... related to ./public handling?
by Joel Roth 31 Oct '11

31 Oct '11

Hi Dancers (and choreographers) My Dancer is v1.3071. I have content in a ./public directory, and in a ./pages directory. The ./pages includes a nested directory structure that mirrors ./public with a page for each directory. For example: ./public/audio/foo/bar.mp3 ./public/audio/baz.mp3 ./pages/audio.txt # lists items under .../audio/ ./pages/audio/foo.txt # lists items under .../audio/foo/ [1] http://mydomain.com/audio [2] http://mydomain.com/audio/foo URL [1] is converted to the file path ./pages/audio.txt, which is rendered from Markdown to HTML and returned. I expect URL [2] to similarly return a rendered form of ./pages/audio/foo.txt, but what I receive is 404. FWIW, the entire app is small enough to append below, however in the interests of politeness, I'm posting this link: http://pastebin.com/kWrUsZZM My log files are not helpful, as I don't seem to be getting any output into them, despite what I believe to be correct configuration. Zero-length log files *do* get created when the app runs. The apache log reported missing Module::Reload errors that I resolved by setting auto_reload: 0 in config.yml. Thanks for any ideas.

https://github.com/richardhuxton/perl-dancer-session-chi Don't be frightened by the low version number - there's only a dozen lines of code or so. I'll try and find the time to sort out a CPAN upload too. -- Richard Huxton Archonet Ltd

Devel::Cover won't cover route handlers?
by Michael Alan Dorman 27 Oct '11

27 Oct '11

Hey, all, So I've got a new application I've been working on, and I decided to do a quick coverage check...and found that Devel::Cover seems to ignore all route handlers. You can see this yourself if you wish: dancer -a TestApp cd TestApp perl Makefile.PL cover -test Look at the coverage report, and there's nothing marked for the / route, even though it has been run. Needless to say, this is a little disappointing, if only because I realized that my 100% green report wasn't necessarily true. ;) Any ideas on how to resolve this issue? Mike.

app works fine but testing fails

25 Oct '11

Terr! I made a little sample app to check out SimpleCRUD plugin, it works fine but when trying to run standard tests bundled with Dancer tests fail like this: $ perl -Ilib t/001_base.t 1..1 Use of uninitialized value in concatenation (.) or string at /home/wanradt/perl5/lib/perl5/Dancer/Plugin/Database.pm line 103. Use of uninitialized value in string eq at /home/wanradt/perl5/lib/perl5/Dancer/Plugin/Database.pm line 112. not ok 1 - use keel; # Failed test 'use keel;' # at t/001_base.t line 5. # Tried to use 'keel'. # Error: Can't connect to data source 'dbi:' because I can't work out what driver to use (it doesn't seem to contain a 'dbi:driver:' prefix and the DBI_DRIVER env var is not set) at /home/wanradt/perl5/lib/perl5/Dancer/Plugin/Database.pm line 147 # Compilation failed in require at (eval 4) line 2. # BEGIN failed--compilation aborted at (eval 4) line 2. # Looks like you failed 1 test of 1. What is problem here? Why test can't see app configuration and use it for DB connection? -- Wbr, Kõike hääd, Gunnar

running a route from another route within Dancer
by Puneet Kishor 25 Oct '11

25 Oct '11

Is something like the following possible (see the line marked />+/)? Or, even advisable? get '/foo.:format' => sub { my $a = param 'a'; my $b = param 'b'; my $res = query_db($a, $b); return to_json $res; } get '/bar.:format' => sub { my $a = param 'a'; my $b = param 'b'; >>>>>> my $res_foo = <somehow call /foo.json?a=$a&b=$b>; my $res = do_something($res_foo); return to_json $res; } -- Puneet Kishor

Dancer2 - feature change request
by Richard Huxton 24 Oct '11

24 Oct '11

Since dancer2 is on the way, I thought I'd be cheeky and suggest a slight change in functionality (rather than wait until dancer3). Does anyone (particularly core devs of course) have any strong opinions on the following? At the moment, the logging levels are exposed directly (debug, warning, error). All the major logging modules seem to expose a single object (Log::Log4perl, Log::Dispatch, Log::Any etc). Doing similar would make logging more consistent across dancer and my non-web modules. To be explicit, I'm suggesting this: debug("current id = $id") would become: log->debug("current id = $id") It's a purely cosmetic change at one level, but it does: 1. Reduce namespace pollution 2. Allow for alternative log-levels I actually think the printf-style functionality of Log::Any is worth stealing too. It lets you do things like: log->debugf("user %d has fields %s", $user_id, $user_hashref) With $user_hashref being automatically piped through Data::Dumper -- Richard Huxton Archonet Ltd
