Ayush Baluni	1d4657b614	internal/download: distinguish missing file from stale in era download ... verifyHash returns an error for both file-not-found (os.Open) and hash mismatch. DownloadFile previously printed 'is stale' for any error. Check errors.Is(err, os.ErrNotExist) to distinguish: - File missing: print 'not found, downloading' - Hash mismatch: print 'is stale' Fixes #31917	2026-03-18 11:39:32 +05:30
Felix Lange	ad88b68a46	internal/download: show progress bar only if server gives length (#33842) ... Fixes this: https://ci.appveyor.com/project/ethereum/go-ethereum/builds/53538177/job/ptosr48pvvwkjskb#L43	2026-02-14 00:00:03 -07:00
Felix Lange	3ceec0ea9b	cmd/geth, internal/era/eradl: add era1 downloader tool (#31823) ... This adds a geth subcommand for downloading era1 files and placing them into the correct location. The tool can be used even while geth is already running on the datadir. Downloads are checked against a hard-coded list of checksums for mainnet and sepolia. ``` ./geth download-era --server $SERVER --block 333333 ./geth download-era --server $SERVER --block 333333-444444 ./geth download-era --server $SERVER --epoch 0-10 ./geth download-era --server $SERVER --all ``` The implementation reuses the file downloader we already had for fetching build tools. I've done some refactoring on it to make sure it can support the new use case, and there are some changes to the build here as well.	2025-05-15 22:53:26 +02:00
