From 5c21e6c6d3843232f384079837da1d9fae573b8d Mon Sep 17 00:00:00 2001 From: John Newbery Date: Thu, 5 Apr 2018 10:17:32 -0400 Subject: [PATCH 1/2] [logging] Comment all continuing logs. Most logs should terminated with a '\n'. Some logs are built up over multiple calls to logPrintf(), so do not need a newline terminater. Comment all of these 'continued' logs as a linter hing. --- src/dbwrapper.cpp | 2 +- src/init.cpp | 2 +- src/sync.cpp | 8 ++++---- src/txdb.cpp | 4 ++-- src/validation.cpp | 8 ++++---- src/wallet/wallet.cpp | 2 +- 6 files changed, 13 insertions(+), 13 deletions(-) diff --git a/src/dbwrapper.cpp b/src/dbwrapper.cpp index ca446c92fe..e401b5fb1b 100644 --- a/src/dbwrapper.cpp +++ b/src/dbwrapper.cpp @@ -63,7 +63,7 @@ public: assert(p <= limit); base[std::min(bufsize - 1, (int)(p - base))] = '\0'; - LogPrintf("leveldb: %s", base); + LogPrintf("leveldb: %s", base); /* Continued */ if (base != buffer) { delete[] base; } diff --git a/src/init.cpp b/src/init.cpp index 4bb2bc2c3e..b1897e0c17 100644 --- a/src/init.cpp +++ b/src/init.cpp @@ -1215,7 +1215,7 @@ bool AppInitMain() // Warn about relative -datadir path. if (gArgs.IsArgSet("-datadir") && !fs::path(gArgs.GetArg("-datadir", "")).is_absolute()) { - LogPrintf("Warning: relative datadir option '%s' specified, which will be interpreted relative to the " + LogPrintf("Warning: relative datadir option '%s' specified, which will be interpreted relative to the " /* Continued */ "current working directory '%s'.
