#1710 | fixed | Major garbage collector runs all the time | ||
Description |
The major garbage collector runs too frequently if you happen to get unfortunate "correct" combination of
(By permanent objects I mean the set of objects that survives a major garbage collection.)
In this situation you can effectively get a major GC for every
This
In practice, the One incarnation of this is a program that gradually gets slower and slower, and then suddenly gets fast again. In this case the sum of permanent objects gets bigger and bigger until the objects no longer fit in the heap. At this point the heap is grown and everything gets smooth again.
One possible workaround is to manually specify a big heap with
One example of affected program: https://stackoverflow.com/questions/62826083/chicken-scheme-read-line-taking-too-long/63215403 (define *corpus* (call-with-input-file "largeish_file.txt" (lambda (input-file) (let loop ([line (read-line input-file)] [tokens '()]) (if (eof-object? line) tokens (loop (read-line input-file) (append tokens (string-split line))))))))
This program generates lots of garbage by creating lots of temporary lists.
Using big heap (using I've posted a patch here: https://lists.nongnu.org/archive/html/chicken-hackers/2020-01/msg00002.html This works by growing the heap if it's too full after a major collection. |

#1708 | fixed | genann: installation broken with CHICKEN 5.2.0 | ||
Description |
The installation of genann fails with CHICKEN 5.2.0 and more recent versions (see http://salmonella-linux-arm64.call-cc.org/master/clang/linux/arm64/2020/07/28/salmonella-report/install/genann.html). This issue is probably related to http://bugs.call-cc.org/ticket/1655. It seems that the patch by Peter has already been applied to the repository (https://github.com/dieggsy/genann/commit/750a1cdfd93ee63dc5b91ab0666e3c852844456e). Maybe you just have to tag a release? |
