From a2e94c9d580d202e5a4ebf1c731a51d187034775 Mon Sep 17 00:00:00 2001 From: Ben Johnson Date: Sat, 23 Jul 2022 08:57:35 -0600 Subject: Add build tag to enable OSTRACE() logging This commit adds the `sqlite_os_trace` build tag which sets the `SQLITE_FORCE_OS_TRACE` and `SQLITE_DEBUG_OS_TRACE` compilation flags. This produces verbose debugging output of every operating system call made by SQLite. --- README.md | 1 + 1 file changed, 1 insertion(+) (limited to 'README.md') diff --git a/README.md b/README.md index e455133..58e315a 100644 --- a/README.md +++ b/README.md @@ -172,6 +172,7 @@ go build --tags "icu json1 fts5 secure_delete" | International Components for Unicode | sqlite_icu | This option causes the International Components for Unicode or "ICU" extension to SQLite to be added to the build | | Introspect PRAGMAS | sqlite_introspect | This option adds some extra PRAGMA statements. | | JSON SQL Functions | sqlite_json | When this option is defined in the amalgamation, the JSON SQL functions are added to the build automatically | +| OS Trace | sqlite_os_trace | This option enables OSTRACE() debug logging.

When this option is not used, secure_delete defaults to off. When this option is present, secure_delete defaults to on.

The secure_delete setting causes deleted content to be overwritten with zeros. There is a small performance penalty since additional I/O must occur.

On the other hand, secure_delete can prevent fragments of sensitive information from lingering in unused parts of the database file after it has been deleted.
