Re-organised all Java source code under the java-api subdirectory, which
also contains a Makefile.in that performs the Java compilation. This
makefile is only invoked if ./configure finds a working Java compiler.
Adds a CLI and RESTful API operation for "keyring remove", with simple
test cases. Added the corresponding Java API operation. Updated the
API documentation.
API change: for consistency with RESTful API design, the GET
/restful/keyring/add operation now returns "201 Created" not "200 OK" if
successful.
The CLI and server main loop now have no conditional JNI code. All JNI
code has been moved into separate source files, which #include the new
"jni_common.h" instead of <jni.h>. The "cli.h" header no longer
includes <jni.h>, so the rest of the Serval source code is now
unaffected by JNI definitions.
The 'cf_limbo' global variable is now thread-local, so that each thread
has its own independent copy of the loaded configuration. The JNI
server entry point now calls cf_init() once. The new 'cf_initialised'
flag prevents clobbering the config state by redundant calls to
cf_init().
The CLI "stop" command now sends SIGHUP to the specific thread in which
the server is running. This is achieved by writing the PID and TID
(Linux Thread ID) into the pidfile, separated by a space, on systems
that support the Linux gettid() and tgkill() system calls. The server's
signal handler has been overhauled, and its logging improved.
The execute() and executeOk() functions now set $TFWEXECUTED instead
of $executed.
The execute() and executeOk() functions now make a hard link from the
--stdout-file=PATH and --stderr-file=PATH files to the default files
of 'stdout' and 'stderr' so that post-fork handling can still cat their
contents into the log file.
The fork() function now sets the variables $TFWFORKSTDOUT_<label>
$TFWFORKSTDERR_<label> $TFWFORKPID_<label>.
Ignores a variety of warnings when compiling sqlite3.c.
Uses the new sqlite3_trace_v2() function for logging SQL statements, now
that sqlite3_trace() and sqlite3_profile() are deprecated.
Fixes a rhizomeops test failure caused because SQLite 3.12 increased the
default block size from 1024 to 4096, causing the fixed overhead of an
empty Rhizome db to exceed 32KB. This caused the test to fail because
the first "file add" failed. Now the test fixture adapts to the fixed
overhead.
Deletes the SQLite 3.10.2 source amalgamation.
The recent randomising of keyring slots broke an assumption
about the order of the 'keyring list' output. Now the test's
assertions do not assume any order.
The in-memory identity creation test was failing intermittently because
the server only creates the in-memory identity on the first tick, and
under load the server sometimes does not tick for a while, leading to a
race with the "servald id self" command.
The test case now waits for the server to emit a tick before running the
"id self" command. This necessitated a new DEBUG() statement and a new
debug flag 'overlaytick'.
Also disabled Rhizome for all the keyring tests, as unnecessary Rhizome
DB creation was slowing down the fixtures.
