Exposing address manager table entries in a hidden RPC allows to introspect
addrman tables in tests and during development.
As response JSON object the following FORMAT1 is choosen:
{
"table": {
"<bucket>/<position>": { "address": "..", "port": .., ... },
"<bucket>/<position>": { "address": "..", "port": .., ... },
"<bucket>/<position>": { "address": "..", "port": .., ... },
...
}
}
An alternative would be FORMAT2
{
"table": {
"bucket": {
"position": { "address": "..", "port": .., ... },
"position": { "address": "..", "port": .., ... },
..
},
"bucket": {
"position": { "address": "..", "port": .., ... },
..
},
}
}
FORMAT1 and FORMAT2 have different encodings for the location of the
address in the address manager. While FORMAT2 might be easier to process
for downstream tools, it also mimics internal addrman mappings, which
might change at some point. Users not interested in the address location
can ignore the location key. They don't have to adapt to a new RPC
response format, when the internal addrman layout changes. Additionally,
FORMAT1 is also slightly easier to to iterate in downstream tools. The
RPC response-building implemenation complexcity is lower with FORMAT1
as we can more easily build a "<bucket>/<position>" key than a multiple
"bucket" objects with multiple "position" objects (FORMAT2).

`Assume` is safer since the checks are non-fatal- errors in these functions
should provide feedback in debug builds, but do not need to deter further node
operations in production.
|

Add an optional parameter to the addrman Select function that allows callers to
specify which network the returned address should be on. Ensure that the proper
table is selected with different cases of whether the new or tried table has
network addresses that match.

The functionality of the old size() is covered by the new Size()
when no arguments are specified, so this does not change behavior.
Co-authored-by: Martin Zumsande <mzumsande@gmail.com>
|
|
For now, the new functionality will be used in the context of
querying fixed seeds. Other possible applications for
future changes is the use in the context of making automatic
connections to specific networks, or making more detailed info
about addrman accessible via rpc.

If AddrMan::Good is unable to add an entry
to tried (for a number of reasons), return false.
This makes it much easier and cleaner to directly
test for tried collisions. It also allows anyone
calling Good() to handle the case where adding an
address to tried is unsuccessful.
Update docs to doxygen style.

22b44fc696dc1078c40d17e2d497c74c7b4ae750 p2p: improve checkaddrman logging with duration in milliseconds (Jon Atack)

325da75a5396f3161a6eade74b349105ed5722ab log, timer: allow not repeating log message on completion (Jon Atack)
Pull request description:
This patch:
- updates the `logging/timer.h::Timer` class to allow not repeating the log message on completion
- adds a `LOG_TIME_MILLIS_WITH_CATEGORY_MSG_ONCE` macro that prints the descriptive message when logging the start but not when logging the completion
- updates the checkaddrman logging to log the duration, and renames the function like the `-checkaddrman` configuration option in order to prefix every log message with `CheckAddrman` instead of the longer, less pleasant, and different-from-checkaddrman `ForceCheckAddrman` (the Doxygen documentation on the function already makes clear that it is unaffected by `m_consistency_check_ratio`).

Pull request description:
Previously, Add() would return true if the function created a new
AddressInfo object, even if that object could not be successfully
entered into the new table and was deleted. That would happen if the new
table position was already taken and the existing entry could not be
removed.
Instead, return true if the new AddressInfo object is successfully
entered into the new table. This fixes a bug in the "Added %i addresses"
log, which would not always accurately log how many addresses had been
added.

p2p_addrv2_relay.py and p2p_addr_relay.py need to be updated since they
were incorrectly asserting on the buggy log (assuming that addresses are
added to addrman, when there could in fact be new table position
collisions that prevent some of those address records from being added).

92617b7a758c0425330fba4b886296730567927c effectively changed the
on-disk format in an incompatible way: old deserializers cannot
deal with multiple entries for the same IP.
Introduce a V4_MULTIPORT format, and increment the compatibility base,
so that old versions correctly recognize it as an incompatible future
version.

and update the function name to CheckAddrman (drop "Force") for
nicer log output as it is prefixed to each of these log messages:
2021-09-21T18:42:50Z [opencon] CheckAddrman: new 64864, tried 1690, total 66554 started
2021-09-21T18:42:50Z [opencon] CheckAddrman: completed (76.21ms)
The existing Doxygen documentation on the function already makes
clear that it is unaffected by m_consistency_check_ratio.

Maintain comments on the external interfaces rather than on the internal
functions that implement them.
|
|
Update so the internal function signature matches the external one, as is the
case for the other addrman functions.

Since knowledge of CAddrInfo is limited to callsites that import
addrman_impl.h, only objects in addrman.cpp or the tests have access. Thus we
can remove calling them friends and make the members public.
|
|
Now that no bitcoind callers require knowledge of the CAddrInfo object, it can
be moved into the test-only header file.

CAddrInfo objects are an implementation detail of how AddrMan manages and adds
metadata to different records. Encapsulate this logic by updating Select &
SelectTriedCollision to return the additional info that the callers need.
|
|
Introduce the pimpl pattern for CAddrMan to separate the implementation details
from the externally used object representation. This reduces compile-time
dependencies and conceptually clarifies AddrMan's interface from the
implementation specifics.
Since the unit & fuzz tests currently rely on accessing CAddrMan internals, this
commit introduces addrman_impl.h, which is exclusively imported by addrman.cpp
and test files.
