Follow-up to #26697, makes the crawler less verbose on route53-based scenarios.
It also changes the loglevel from debug to info on Updates, which are typically the root, and can be interesting to see.
This change updates our urfave/cli dependency to the v2 branch of the library.
There are some Go API changes in cli v2:
- Flag values can now be accessed using the methods ctx.Bool,
ctx.Int, ctx.String, ... regardless of whether the flag is 'local' or
'global'.
- v2 has built-in support for flag categories. Our home-grown category
system is removed and the categories of flags are assigned as part of
the flag definition.
For users, there is only one observable difference with cli v2: flags must now
strictly appear before regular arguments. For example, the following command is
now invalid:
geth account import mykey.json --password file.txt
Instead, the command must be invoked as follows:
geth account import --password file.txt mykey.json
* cmd/devp2p: fix comparison of TXT record value
The AWS API returns quoted DNS strings, so we must encode the new value
before comparing it against the existing record content.
* cmd/devp2p: add test
* cmd/devp2p: fix typo and rename val -> newValue
This PR fixes a regression introduced in #22360, when we updated to the v2 of the AWS sdk, which causes current crawler to just get the same first 100 results over and over, and get stuck in a loop.
This updates the DNS deployer to use AWS SDK v2. Migration is relatively
seamless, although there were two locations that required a slightly
different approach to achieve the same results. In particular, waiting for
DNS change propagation is very different with SDK v2.
This change also optimizes DNS updates by publishing all changes before
waiting for propagation.
Turns out the way RDATA limits work is documented after all,
I just didn't search right. The trick to make it work is to
count UPSERTs twice.
This also adds an additional check to ensure TTL changes are
applied on existing records.
For longer records and subtree entries, the deployer created two
separate TXT records. This doesn't work as intended because the client
will receive the two records in arbitrary order. The fix is to encode
longer values as "string1""string2" instead of "string1", "string2".
This encoding creates a single record on AWS Route53.
This change works around the 32k RDATA character limit per change
request and fixes several issues in the deployer which prevented it from
working for our production trees.
