Hi everyone,
I'm currently working on implementing and integrating VRE_encode/decode
functions as evoked here
https://github.com/varnishcache/varnish-cache/issues/4334
The goal here is to properly de/serialize bans using
pcre2_serialize_encode/decode functions
What is currently done is that the ban spec is simply written to a VSB,
so what I attempted is to iterate over the ban spec, write the non-regex
parts to the VSB just as it is done now, but when I encounter then I
de/serialize it and then write it to the VSB.
Here is my WIP
https://github.com/varnishcache/varnish-cache/compare/master...cartoush:varnish-cache:pcre_serialize_bans
But what I'm stuck with is that simply iterating over a ban spec causes
crashes like so:
```
*** v1 debug|Assert error in ban_get_lump(), cache/cache_ban.c line 212:
*** v1 debug| Condition(PAOK(*bs)) not true.
```
even though I took example from other places in VC where ban_iter is
used and seems to work correctly.
Here is a minimal demonstration of how to reproduce that:
https://github.com/varnishcache/varnish-cache/compare/master...cartoush:varnish-cache:test_iter_cache_ban
So my question here is: Is ban_iter simply not the tool I should be
using to iterate over bans here and if not what could I use ? And if yes
what am I doing wrong here ?
Best regards,
