libvmod-netmapper: must specify ABI stanza
Closed, ResolvedPublic
Actions

Description

Starting with 6.0.0, VMOD descriptions can specify an ABI stanza. The valid values are either vrt or strict (the default). Strict means that VMODs built against a specific Varnish version will only work on that version, regardless of the ABI compatibility declared with VRT_MAJOR/MINOR . libvmod-netmapper currently does not set $ABI, hence a binary build of the netmapper module against 6.0.6 does not work against 6.0.4:

**** v1    0.1 CLI RX|\tFile name: /usr/lib/x86_64-linux-gnu/varnish/vmods/libvmod_netmapper.so
**** v1    0.1 CLI RX|\tABI mismatch, expected <Varnish 6.0.4 14d4eee6f0afc3020a044341235f54f3bd1449f1>, got <Varnish 6.0.6 29a1a8243dbef3d973aec28dc90403188c1dc8e7>

@Vgutierrez, since you were involved with the libvmod-netmapper upgrades, would you say that this 2-year-old issue is fixed?

BCornwall added a comment.Jan 9 2023, 6:30 PM

Ugh, sorry, meant to put that in T266651
