- make "debug.h" a private header so that the DEBUG() macro does not
interfere with Xcode Debug builds, which set DEBUG=1
- move all #include "debug.h" from headers into .c files
- move 'struct idebug' into a new public header "idebug.h" so that
"log.h" can be public
- move HTTPD port number defs from "httpd.h" to "constants.h", so that
"httpd.h" can be private and "conf.h" can be public
- add missing nested includes so each header compiles stand-alone
without error
- #include "sodium.h" instead of <sodium.h>
- #include "sqlite3.h" instead of <sqlite3.h>
- add header guard to "fifo.h"
- fix header guard in "sync_keys.h"
The new 'cmd_cleanup' trigger replaces the old command_cleanup()
function, which was causing linking problems on OS X and inverted strict
dependency. The keyring cmd_cleanup calls keyring_free(global_keyring),
instead of merely asserting keyring == NULL, so the error exit cases of
many CLI functions have been simplified.
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.
Add RHIZOME_BUNDLE_STATUS_MANIFEST_TOO_BIG enum option to indicate
that the manifest exceeded 8 KiB in size.
Refactor rhizome_add_manifest() and rhizome_manifest_finalise()
to return 'struct rhizome_bundle_result' instead of 'enum
rhizome_bundle_status', so that that their detailed failure messages
can reach the HTTP API layer instead of just being logged.
Fix HTTP response status codes produced Rhizome direct HTTP requests
to be consistent with the Rhizome RESTful API.
- Introduce the new 'struct rhizome_bundle_result' that contains a
rhizome_bundle_status enum value and an optional, nul-terminated
string that provides an explanation of the cause of the status; add
functions to construct, query, and free the struct
- Replace 'enum rhizome_add_result' with 'struct rhizome_bundle_result',
removing an unnecessary level of enum interpretation
- Make rhizome_fill_manifest() return 'struct rhizome_bundle_result' and
add logic to check that the supplied author SID is correct (previous
behaviour was: if an incorrect author SID was supplied but the correct
author could be found in the keyring, then the incorrect one was
silently ignored)
- Simplify the response code in rhizome_restful.cc to take advantage of
the new 'struct rhizome_bundle_result'; in particular, the mapping
from 'enum rhizome_bundle_status' codes to HTTP status codes is now
expressed in a single switch statement
- Fix some minor failures in test scripts revealed by the changes
Need a way for the client to distinguish between authenticated (certain)
and unauthenticated (likely) author SIDs in the context of a bundle list,
since the bundle list does not verify manifest signatures for performance
and battery life reasons.
Original DEBUG() and DEBUGF() macros renamed to _DEBUG() and _DEBUGF()
New DEBUG() and DEBUGF() macros, first argument is flagname
New DEBUGF2(foo, bar, ...) macro does if(config.debug.foo||config.debug.bar) test
Replace almost all config.debug.xxx references to IF_DEBUG(xxx)
A convenience to re-use an existing manifest, instead of having
to extract the manifest, erase some fields, then pass the result
back into the 'rhizome add file' command
Distinguish between fatal and user-supplied-input errors, return
error descriptive text in a strbuf to allow dynamic content, apply
user-supplied field assgnments/deletions _after_ copying existing
manifest fields, use exit status 4 (invalid manifest) when applying
journal append to a non-journal or vice versa
Put manifest creation logic into new rhizome_bundle_add_file()
function, in preparation for implementing new HTTP POST
/restful/rhizome/append request
Several 'rhizomeops' tests fail
Now a new manifest can be formed, and an existing manifest modified, by
giving "field=value" or "!field" command-line arguments at the end of
the "rhizome add file" command (after the <bsk> argument).
This makes it easier to script rhizome operations.
