[GitHub] [trafficserver] c-taylor opened a new issue, #8780: pcre library needs review
c-taylor opened a new issue, #8780:
URL: https://github.com/apache/trafficserver/issues/8780
Current issues are:
* pcre library is no longer maintained; author working on pcre2
* pcre jit support in ATS is incomplete
* https://issues.apache.org/jira/browse/TS-3143
* https://issues.apache.org/jira/browse/TS-3144
* Library review
* Should probably look at pcre2/je2 (or others)

Whilst looking at some high RPS rate tests libpcre was starting to 'feature' in traces.
The obvious optimisation for libpcre is to use the jit support, which probably lends itself well to constrained lists of regex.
However, given the above an "architectural review" is probably required before more effort is spent...

It looks like trafficserver precompiles the expressions, replacing the need/benefit of the jit… Perhaps someone can confirm…
So really this may just be a “what’s the long term plan” question… Given status of pcre project…
