Subject: $CPAN::Config{'build_cache'} ignored in 1.9101

Hello, in CPAN 1.9101 (probably since CPAN 1.90), the maximum size for the build directory $CPAN::Config{'build_cache'} ist not honored anymore. After downgrade to CPAN 1.8802 the next invocation starts removing old directories again. On some installations with restricted disk space, this has led to disk full conditions. Verified on SuSE Linux 8.1, 8.2, 9.2, 10.0 and Debian Sarge. Best regards Matthias Ferdinand

I'm surprised, this does not match my observations. There must be something going on that I do not know of. How large is your build_cache? What does CPAN.pm say, when you start the shell and then do your first install or test or make command? Show quoted text

Please supply details how you do the verification. I write several Gigabytes every day to my build_dir. What is your value for scan_cache? Try 'o conf init scan_cache'. -- andreas

Hi again, just for documentation purposes I quote some from my answer to #26886. As I carelessly did not state in the initial report, I did not use the CPAN shell, but a script to report changelogs. A sketch of what it does (including the workaround for #26886): Show quoted text

build_cache = 'build_cache' => q[100], 'build_dir' => q[/root/.cpan/build], 'build_dir_reuse' => q[1], 'build_requires_install_policy' => q[ask/yes], ... 'scan_cache' => q[atstart], (atstart was already set before I did "o conf init"). Show quoted text

Not sure about that. Up to version 1.8802 and using $CPAN::Config->{'scan_cache'}='atstart', the build cache cleanup was triggered automatically just by using my changelog reader. I think it would not hurt if this behaviour was re-instated. Otherwise I would need to write code depending on CPAN version in the script. Best regards Matthias
