Stack:

Nginx FCGI CGI::Fast HTML::Template::Compiled Redis CentOS Linux 7.9 spawn-fcgi 

On process init it does a lot of loading of big hashes and other data into global variables that are mostly preloaded and cached in a distributed Redis install.

To start the application spawn-fcgi creates 6-8 processes on a port nginx then connects to trhough their fcgi module.

The challenge:

— The init process is computing and time consuming; and doing that concurrently six times peaks CPU and overall leads to a ~20-25 second delay before the next web request can be served. And the initial request to each of the six processes has that delay.

I tried loading the content in question directly from Redis on demand but the performance keeping it in memory is naturally much better (minus the initial delay).

is there an architectural pattern that I am not considering here? I am thinking of things as eg. only spinning up one process, having it initialize and then clone(?) it a few times for serving more requests.

I could also think of a way where only 1 process is spawned at a time and once it completes initiation the next one starts; would need to verify that spawn-fcgi can support this.

So my question to this community is if I am missing an obvious better solution than what is in place right now / what I am considering.

Thanks in advance.

I am moving a pile of stuff off of an older Intel Mac Mini onto an M2. Have almost everything migrated, but am stuck on getting a Perl script that relies heavily on DBD::mysql to work. I finally got cpan to build the module, but when I try to use it in actual code, I get: dyld[82852]: missing symbol called. I go through this mess periodically with OS upgrades...and it's possible that this is (once again) OSX ignoring the module because it's not signed. But the given error sounds more like Perl not finding the dynamic library(s) the module was built with...if I just have a script containing "use DBD::mysql;", that doesn't throw an error, which suggests Perl found the module and loaded it. But chokes when it tries to use it.

I'd be fine with building this module with static libraries, if the process of doing so is easy. But have not seen an easy option to cpan to go that route. Suggestions?

• Add tests for error parameters.
• Rewrite the tests so that the functional tests are first and then the errors.

Hi! Asking for a wisdom here...

We have a module that modifies signal handler $SIG{__DIE__} to log information and to die afterwards. Hundreds of scripts relied on this module which worked fine in perl 5.10.1.

Recently we had the opportunity to install several Perl versions but unfortunately a large number of scripts that used to work with Perl 5.10.1 now behave differently:

• Failed in 5.14.4: /home/dev/perl-5.14.4/bin/perl -wc test.pl RECEIVED SIGNAL - S_IFFIFO is not a valid Fcntl macro at /home/dev/perl-5.14.4/lib/5.14.4/File/stat.pm line 41
• Worked without changes in 5.26.3: /home/dev/perl-5.26.3/bin/perl -wc test.pl test.pl syntax OK
• Worked without changes in 5.38.2: /home/dev/perl-5.38.2/bin/perl -wc test.pl test.pl syntax OK

Many of the scripts can only be updated to 5.14.4 due to the huge jumps between 5.10 and 3.58; But we are stuck on that failures.

Was there an internal Perl change in 5.14 which cause the failures but works on other recent versions without any update on the scripts?

Cheerio!

My environment is perl/5.18.2 on CentOs 7

I'm trying to use a SWIG generated module in perl, which has a c plus plus backend. The backend.cpp sets an environment variable, $MY_ENV_VAR =1

But when I try to access this in perl, using $ENV{MY_ENV_VAR} this is undef.

However doing something like print echo $MY_ENV_VAR works

So the variable is set in the process, but it's not reflected automatically since nothing updates the $ENV data structure.

I'm assuming it may work using some getEnv like mechanism, but is there a way to reset/ refresh the $ENV that it rebuilds itself from the current environment?
