swiftc(1) requires every -D option to be prefixed with -Xcc, which
is not easy to achieve using autoconf.
Now instead of setting configuration macros like HAVE_LSEEK64 on the
command line using -D, they are defined in config.h, which is generated
by ./configure, ignored by Git, and included by all headers and source
files that use any configuration macro.
The dependency on Makefile has been replaced with a dependency on
Makefile.in and config.h, which helps avoid some redundant full
recompiles after running ./configure, because the configure script
does not overwrit config.h if its content does not change.
Recent changes such as the Makefile.in overhaul and the introduction of
feature-driven linking broke the Android build. This commit fixes the
breakage:
- detects the presence of gettid() in configure.ac and only defines
gettid() in serval.c if HAVE_GETTID is not defined
- builds libserval.so not libservald.so on Android, to avoid a conflict
on the module name "servald" in Android.mk
- renames cli_cleanup() to command_cleanup(), defines it in
commandline.h instead of cli.h, and supplies it in android.c
- supplies the 'keyring' global in android.c
- removes log_stderr.c from the Android build, since it conflicted with
log.c
This introduces a new way of linking Serval executables and dynamic
libraries from static libraries like libservald.a -- called
"feature-driven" linking.
The Makefile now links servald and serval-tests from libservald.a,
rather than from an explicit list of object (.o) files. Thanks to the
section-based method for registering functions such as HTTP handlers,
CLI commands and MDP handlers, these object files had become
"stand-alone" and hence were no longer included in the link because
there was no unresolved reference that required them to be linked in.
The new "feature.h" provides the DECLARE_FEATURE(name) macro that each
stand-alone source file uses to declare the named feature(s) it
provides. Each executable can call the USE_FEATURE(name) macro in any
of its explicitly-linked source files to cause the corresponding
object(s) to be included in the link, eg, servald_features.c.
The DEFINE_BINDING() macro has been extended so that every individual
MDP binding is given a feature name based on its port number macro, eg,
"mdp_binding_MDP_PORT_ECHO".
Some features have been factored into their own separate source files so
they can be omitted or included in a build independently of each other:
- the MDP bindings for MDP_PORT_DNALOOKUP, MDP_PORT_ECHO,
MDP_PORT_TRACE, MDP_PORT_KEYMAPREQUEST, MDP_PORT_RHIZOME_xxx,
MDP_PORT_PROBE, MDP_PORT_STUN, MDP_PORT_STUNREQ
- the CLI "log" and "echo" commands
- the CLI "rhizome direct" command
The JNI source files are only compiled if the <jni.h> header is present,
otherwise they are omitted from libservald.so.
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.
Changed the built libraries and updated INSTALL.md accordingly:
- the 'servaldwrap' executable is now built
- libservald.[a,so] now contains the full daemon executable
- libservalclient.[a,so] contains the client library
- libserval.a is no longer built
Building the 'servaldwrap' executable is a step towards ensuring that
the libservald.so library can be linked and executed, without requiring
an Android build to reveal any failure.
Added the SOURCE_PREFIX variable that allows the make to be invoked from
within any current working directory, not just the serval-dna
repository's root directory.
Fixed the serval_version.o target to invoke the version_string.sh
script with the --repository=DIR option, so that the build will work
even if the current working directory is not within the serval-dna
repository.
Re-ordered and added some comments for clarity, and added some missing
.PHONY declarations.
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.
Was not passing $(CFLAGS) $(DEFS) to compile servald_version.c, which
provoked a "cc1: note: someone does not honour COPTS correctly, passed 0
times" warning
Also was not doing "mkdir -p opts" before the compile, which produced an
"opts/version.o: No such file or directory: error
Make .o files in separate subdirectories for servald and library
Factor struct __sourceloc and __WHENCE__ from "log.h" into "whence.h"
Factor sid_t etc from "serval.h" into "serval_types.h"
Factor rhizome_bid_t etc from "rhizome.h" into "rhizome_types.h"
Do not include "serval.h" in library sources
Add log_stderr.c and logMessage.c for stand-alone executables
If no instance directory specified, then use paths like
/etc/serval/serval.conf
/var/cache/serval
/var/log/serval
/var/run/serval
etc. for files, instead of all in a single directory.
Log all directory creation as INFO messages.
Interpretation of log.file.directory_path has changed slightly.
Updated servald configuration tech doc.
Immediate benefit: does not recompile sqlite3.c when any Serval header
file is touched.
Also makes it a bit clearer which source files are imported and which
can be used in "client" binaries other than servald.
Copyright notices added to most source files and headers
New 'config_test' make target
Add RHIZOME_BUNDLE_ID_xxx, deprecate RHIZOME_MANIFEST_ID_xxx

Move log-implementation-independent code from log.c to log_util.c (new)
Build config_test binary in Makefile
Finish the work started by Daniel in 2012, by using abstract local
AF_UNIX sockets on platforms that support them (Linux, Android).
Fix all sorts of bugs and issues that prevented the existing MDP and
Monitor client and server code from working with abstract socket names.
Full --help usage message
