Merge #6239: feat: increase the number of block headers able to be downloaded at once to 8000 in protocol version 70235
48c7f98b1a
doc: drop trailing whitespace (pasta)697743d77b
test: add missing import (UdjinM6)cfe99fd289
docs: add release notes for 6239 (pasta)a6bbaacfaa
fix: GetHeadersLimit is used for getheaders(2) and headers(2), refactor it to accept `compressed` instead of `msg_type` (UdjinM6)b224f3f6ca
bump p2p_version in tests (PastaPastaPasta)b423f42aae
refactor: sort imports (UdjinM6)f6c68ba71b
refactor: simplify _compute_requested_block_headers (UdjinM6)07876b2c4a
use `MAX_HEADERS_UNCOMPRESSED_RESULT` not `MAX_HEADERS_UNCOMPRESSED_RESULTS` ; use `MAX_HEADERS_UNCOMPRESSED_RESULT` in RPC to avoid breaking changes (pasta)b137280df4
change to _COMPRESSED or _UNCOMPRESSED (pasta)303bc7af99
fix: increase it for headers2 only (UdjinM6)e23410ffdd
trivial: rename `MAX_HEADERS_RESULTS_NEW` to `MAX_HEADERS_RESULTS` (Kittywhiskers Van Gogh)bcf0320691
trivial: move the headers limit determination to `GetHeadersLimit()` (Kittywhiskers Van Gogh)993c7c0f90
feat: increase the number of block headers able to be downloaded at once to 8000 in protocol version `70234` (pasta) Pull request description: ## Issue being fixed or feature implemented We did some testing quite a while ago that found that sending 8000 headers at a time could speed stuff up. But we wanted to wait until compressed headers were implemented. Well, they've been implemented! ## What was done? Bump 2000 -> 8000 triggered by protocol version ## How Has This Been Tested? Hasn't, we should setup a few nodes running this and sync them from each other ## Breaking Changes New protocol version, not breaking but should add notes? I should probably add release notes ## Checklist: _Go over all the following points, and put an `x` in all the boxes that apply._ - [ ] I have performed a self-review of my own code - [ ] I have commented my code, particularly in hard-to-understand areas - [ ] I have added or updated relevant unit/integration/functional/e2e tests - [ ] I have made corresponding changes to the documentation - [x] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ ACKs for top commit: UdjinM6: light ACK48c7f98b1a

P2P and Network Changes
|
||||||
|
-----------------------
|
||||||
|
|
||||||
|
The max number of compressed block headers which can be requested at once has been increased from 2000 to 8000. This
|
||||||
|
change activates with the protocol version `70235` and only applies to compressed block headers.
