2017-08-21cryptonote_protocol: misc fixes to the new sync algorithmmoneromooo-monero1-0/+2
Fix sync wedge corner case: It could happen if a connection went into standby mode, while it was the one which had requested the next span, and that span was still waiting for the data, and that peer is not on the main chain. Other peers can then start asking for that data again and again, but never get it as only that forked peer does. And various other fixes

2017-06-15Don't issue a new timedsync while one is already in progressHoward Chu1-2/+6
A timedsync is issued every minute on a connection, but the input tineout is 2 minutes. This means a new sync request could be issued while a slow sync request was already in progress. The additional request will further clog the network on a slow connection, and cause a premature timeout.
2017-05-27abstracted nework addressesmoneromooo-monero6-189/+320
All code which was using ip and port now uses a new IPv4 object, subclass of a new network_address class. This will allow easy addition of I2P addresses later (and also IPv6, etc). Both old style and new style peer lists are now sent in the P2P protocol, which is inefficient but allows peers using both codebases to talk to each other. This will be removed in the future. No other subclasses than IPv4 exist yet.

The connection is closed after the check in either case.

2017-01-16Change logging to easylogging++moneromooo-monero5-427/+91
This replaces the epee and data_loggers logging systems with a single one, and also adds filename:line and explicit severity levels. Categories may be defined, and logging severity set by category (or set of categories). epee style 0-4 log level maps to a sensible severity configuration. Log files now also rotate when reaching 100 MB. To select which logs to output, use the MONERO_LOGS environment variable, with a comma separated list of categories (globs are supported), with their requested severity level after a colon. If a log matches more than one such setting, the last one in the configuration string applies. A few examples: This one is (mostly) silent, only outputting fatal errors: MONERO_LOGS=*:FATAL This one is very verbose: MONERO_LOGS=*:TRACE This one is totally silent (logwise): MONERO_LOGS="" This one outputs all errors and warnings, except for the "verify" category, which prints just fatal errors (the verify category is used for logs about incoming transactions and blocks, and it is expected that some/many will fail to verify, hence we don't want the spam): MONERO_LOGS=*:WARNING,verify:FATAL Log levels are, in decreasing order of priority: FATAL, ERROR, WARNING, INFO, DEBUG, TRACE Subcategories may be added using prefixes and globs. This example will output net.p2p logs at the TRACE level, but all other net* logs only at INFO: MONERO_LOGS=*:ERROR,net*:INFO,net.p2p:TRACE Logs which are intended for the user (which Monero was using a lot through epee, but really isn't a nice way to go things) should use the "global" category. There are a few helper macros for using this category, eg: MGINFO("this shows up by default") or MGINFO_RED("this is red"), to try to keep a similar look and feel for now. Existing epee log macros still exist, and map to the new log levels, but since they're used as a "user facing" UI element as much as a logging system, they often don't map well to log severities (ie, a log level 0 log may be an error, or may be something we want the user to see, such as an important info). In those cases, I tried to use the new macros. In other cases, I left the existing macros in. When modifying logs, it is probably best to switch to the new macros with explicit levels. The --log-level options and set_log commands now also accept category settings, in addition to the epee style log levels.

Bockchain: 1. Optim: Multi-thread long-hash computation when encountering groups of blocks. 2. Optim: Cache verified txs and return result from cache instead of re-checking whenever possible. 3. Optim: Preload output-keys when encoutering groups of blocks. Sort by amount and global-index before bulk querying database and multi-thread when possible. 4. Optim: Disable double spend check on block verification, double spend is already detected when trying to add blocks. 5. Optim: Multi-thread signature computation whenever possible. 6. Patch: Disable locking (recursive mutex) on called functions from check_tx_inputs which causes slowdowns (only seems to happen on ubuntu/VMs??? Reason: TBD) 7. Optim: Removed looped full-tx hash computation when retrieving transactions from pool (???). 8. Optim: Cache difficulty/timestamps (735 blocks) for next-difficulty calculations so that only 2 db reads per new block is needed when a new block arrives (instead of 1470 reads). Berkeley-DB: 1. Fix: 32-bit data errors causing wrong output global indices and failure to send blocks to peers (etc). 2. Fix: Unable to pop blocks on reorganize due to transaction errors. 3. Patch: Large number of transaction aborts when running multi-threaded bulk queries. 4. Patch: Insufficient locks error when running full sync. 5. Patch: Incorrect db stats when returning from an immediate exit from "pop block" operation. 6. Optim: Add bulk queries to get output global indices. 7. Optim: Modified output_keys table to store public_key+unlock_time+height for single transaction lookup (vs 3) 8. Optim: Used output_keys table retrieve public_keys instead of going through output_amounts->output_txs+output_indices->txs->output:public_key 9. Optim: Added thread-safe buffers used when multi-threading bulk queries. 10. Optim: Added support for nosync/write_nosync options for improved performance (*see --db-sync-mode option for details) 11. Mod: Added checkpoint thread and auto-remove-logs option. 12. *Now usable on 32-bit systems like RPI2. LMDB: 1. Optim: Added custom comparison for 256-bit key tables (minor speed-up, TBD: get actual effect) 2. Optim: Modified output_keys table to store public_key+unlock_time+height for single transaction lookup (vs 3) 3. Optim: Used output_keys table retrieve public_keys instead of going through output_amounts->output_txs+output_indices->txs->output:public_key 4. Optim: Added support for sync/writemap options for improved performance (*see --db-sync-mode option for details) 5. Mod: Auto resize to +1GB instead of multiplier x1.5 ETC: 1. Minor optimizations for slow-hash for ARM (RPI2). Incomplete. 2. Fix: 32-bit saturation bug when computing next difficulty on large blocks. [PENDING ISSUES] 1. Berkely db has a very slow "pop-block" operation. This is very noticeable on the RPI2 as it sometimes takes > 10 MINUTES to pop a block during reorganization. This does not happen very often however, most reorgs seem to take a few seconds but it possibly depends on the number of outputs present. TBD. 2. Berkeley db, possible bug "unable to allocate memory". TBD. [NEW OPTIONS] (*Currently all enabled for testing purposes) 1. --fast-block-sync arg=[0:1] (default: 1) a. 0 = Compute long hash per block (may take a while depending on CPU) b. 1 = Skip long-hash and verify blocks based on embedded known good block hashes (faster, minimal CPU dependence) 2. --db-sync-mode arg=[[safe|fast|fastest]:[sync|async]:[nblocks_per_sync]] (default: fastest:async:1000) a. safe = fdatasync/fsync (or equivalent) per stored block. Very slow, but safest option to protect against power-out/crash conditions. b. fast/fastest = Enables asynchronous fdatasync/fsync (or equivalent). Useful for battery operated devices or STABLE systems with UPS and/or systems with battery backed write cache/solid state cache. Fast - Write meta-data but defer data flush. Fastest - Defer meta-data and data flush. Sync - Flush data after nblocks_per_sync and wait. Async - Flush data after nblocks_per_sync but do not wait for the operation to finish. 3. --prep-blocks-threads arg=[n] (default: 4 or system max threads, whichever is lower) Max number of threads to use when computing long-hash in groups. 4. --show-time-stats arg=[0:1] (default: 1) Show benchmark related time stats. 5. --db-auto-remove-logs arg=[0:1] (default: 1) For berkeley-db only. Auto remove logs if enabled. **Note: lmdb and berkeley-db have changes to the tables and are not compatible with official git head version. At the moment, you need a full resync to use this optimized version. [PERFORMANCE COMPARISON] **Some figures are approximations only. Using a baseline machine of an i7-2600K+SSD+(with full pow computation): 1. The optimized lmdb/blockhain core can process blocks up to 585K for ~1.25 hours + download time, so it usually takes 2.5 hours to sync the full chain. 2. The current head with memory can process blocks up to 585K for ~4.2 hours + download time, so it usually takes 5.5 hours to sync the full chain. 3. The current head with lmdb can process blocks up to 585K for ~32 hours + download time and usually takes 36 hours to sync the full chain. Averate procesing times (with full pow computation): lmdb-optimized: 1. tx_ave = 2.5 ms / tx 2. block_ave = 5.87 ms / block memory-official-repo: 1. tx_ave = 8.85 ms / tx 2. block_ave = 19.68 ms / block lmdb-official-repo (0f4a036437fd41a5498ee5e74e2422ea6177aa3e) 1. tx_ave = 47.8 ms / tx 2. block_ave = 64.2 ms / block **Note: The following data denotes processing times only (does not include p2p download time) lmdb-optimized processing times (with full pow computation): 1. Desktop, Quad-core / 8-threads 2600k (8Mb) - 1.25 hours processing time (--db-sync-mode=fastest:async:1000). 2. Laptop, Dual-core / 4-threads U4200 (3Mb) - 4.90 hours processing time (--db-sync-mode=fastest:async:1000). 3. Embedded, Quad-core / 4-threads Z3735F (2x1Mb) - 12.0 hours processing time (--db-sync-mode=fastest:async:1000). lmdb-optimized processing times (with per-block-checkpoint) 1. Desktop, Quad-core / 8-threads 2600k (8Mb) - 10 minutes processing time (--db-sync-mode=fastest:async:1000). berkeley-db optimized processing times (with full pow computation) 1. Desktop, Quad-core / 8-threads 2600k (8Mb) - 1.8 hours processing time (--db-sync-mode=fastest:async:1000). 2. RPI2. Improved from estimated 3 months(???) into 2.5 days (*Need 2AMP supply + Clock:1Ghz + [usb+ssd] to achieve this speed) (--db-sync-mode=fastest:async:1000). berkeley-db optimized processing times (with per-block-checkpoint) 1. RPI2. 12-15 hours (*Need 2AMP supply + Clock:1Ghz + [usb+ssd] to achieve this speed) (--db-sync-mode=fastest:async:1000).

2015-05-25Fix compile for GCC 5.1.0warptangent1-1/+5
Add fix for compile error with multiple uses of peerid_type (uint64_t) variable in lambda expression. - known GCC issue: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65843 epee: replace return value of nullptr for expected boolean with false. Fixes #231.
2015-05-25Build seed node list without duplicateswarptangent1-31/+36
The random selection of a node shouldn't favor repeats that occur in the hardcoded and DNS seed node lists. Remove hardcoded ":18080" address which gives parse error. Test: bitmonerod --log-level 2 The seed node list displayed at startup shouldn't show duplicate addresses (includes port).

+toc -doc -drmonero Fixed the windows path, and improved logging and data (for graph) logging, fixed some locks and added more checks. Still there is a locking error, not added by my patches, but present in master version (locking of map/list of peers).
2015-02-24Daemonize changes pulled in -- daemon buildsThomas Winget2-4/+7
many RPC functions added by the daemonize changes (and related changes on the upstream dev branch that were not merged) were commented out (apart from return). Other than that, this *should* work...at any rate, it builds, and that's something.
2015-02-202014 network limit 1.2 +utils +toc -doc -drmonerorfree2monero6-52/+55
new update of the pr with network limits more debug options: discarding downloaded blocks all or after given height. trying to trigger the locking errors. debug levels polished/tuned to sane values. debug/logging improved. warning: this pr should be correct code, but it could make an existing (in master version) locking error appear more often. it's a race on the list (map) of peers, e.g. between closing/deleting them versus working on them in net-limit sleep in sending chunk. the bug is not in this code/this pr, but in the master version. the locking problem of master will be fixed in other pr. problem is ub, and in practice is seems to usually cause program abort (tested on debian stable with updated gcc). see --help for option to add sleep to trigger the error faster.
2015-02-202014 network limit 1.1 +utils +toc -doc -drmonerorfree2monero9-183/+293
Update of the PR with network limits works very well for all speeds (but remember that low download speed can stop upload because we then slow down downloading of blockchain requests too) more debug options fixed pedantic warnings in our code should work again on Mac OS X and FreeBSD fixed warning about size_t tested on Debian, Ubuntu, Windows(testing now) TCP options and ToS (QoS) flag FIXED peer number limit FIXED some spikes in ingress/download FIXED problems when other up and down limit
2015-02-202014 network limit 1.0a +utils +toc -doc -drmonerorfree2monero9-47/+1541
commands and options for network limiting works very well e.g. for 50 KiB/sec up and down ToS (QoS) flag peer number limit TODO some spikes in ingress/download TODO problems when other up and down limit added "otshell utils" - simple logging (with colors, text files channels)
2015-01-14Fix seed node threaded DNS lookupwarptangent1-28/+41
Use copied value of seed node index during thread creation, not reference. - fixes segfault Use boost::thread::try_join_until() instead of an atomic flag result variable for each thread. Add and handle interrupt for thread timeout. - fixes segfault where a thread exceeds requested timeout and tries to assign results to a referenced, but now out-of-scope, variable in the main thread.

2014-09-15Fix time_t serialization issueZachary Michaels3-5/+9
On 32-bit MinGW-w64, time_t is int32_t. The existing code was serializing time_t directly and implicitly assuming that time_t is int64_t. This commit formalizes that assumption by serializing int64_t directly and casting to time_t where appropriate. Thanks go to greatwolf for reporting this issue. monero-project/bitmonero#88

2014-07-01Allow priority peers when there are exclusive peersZachary Michaels1-1/+1
Per my reading this change makes sense since a subset of the exclusive peers could be priority peers. Priority peers that are not exclusive will not get loaded, and priority peers that *are* exclusive will get special treatment. Prior to this change it looks like priority peers were silently ignored when exclusive peers were provided.
