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.
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.
List all the HTTP status codes in the REST API tech doc.
Only use 403 Forbidden for requests originating from a disallowed
origin (ie, not localhost).
- Return 400 for missing, unknown, duplicate and out-of-order form
parts in POST requests.
- Return 415 Unsupported Media Type for unsupported form part
Content-Disposition and Content-Type (including unsupported
charset).
- Return 414 Request-URI Too Long for any buffer exhaustion while
parsing request.
- Return 419 Authentication Timeout for missing crypto secret.
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
All strn_to_xxx() functions should take a 'size_t len' parameter
All functions that take a 'const char **endp' parameter should
be named parse_xxx(), and should also have a 'ssize_t len' parameter
which can be -1 to indicate a null-terminated string
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
The "#passphrase" notation was already supported, and now the RESTful
API can be used to create and update anonymous and authored bundles
using only the bundle secret, just like the CLI.
The OpenJDK 7 recently introduced the UNUSED() macro in their jni_md.h
header file, which is included from <jni.h>. This causes a
compile-error if "constants.h", which defines our own UNUSED() macro, is
included as well as <jni.h>.
The OpenJDK UNUSED() macro is unsuitable for our own use, because it
prefixes the unused identifier with "UNUSED_" whereas we depend on the
parameter name remaining unchanged.
I have reported this as a Request for Enhancement with Oracle Java,
asking them to remove the UNUSED() macro, since it is not used by any
JNI or Java extension header files. Review ID: JI-9013689.
In the meantime, constants.h now undefines UNUSED before defining it, so
including <jni.h> before "constants.h" will avoid a compile error.
Change manifest Content-Type from rhizome-manifest/text to
rhizome/manifest; format="text+binarysig"
Add "Content-Transfer-Encoding" form-part headers to Java API
sent form parts, although not currently checked by Rhizome
RESTful interface
Add RHIZOME_BUNDLE_STATUS_READONLY enum value
Tighten up switch statements on bundle and payload status enums (no
default labels)
Rename some recently added enum entries
Return bundle status and payload status in HTTP responses
Add test for failing to decrypt a foreign encrypted bundle payload,
fix bug that caused an assertion failure
Add tests for fetching a non-existent manifest and fetching bundles
whose payload blob is not in the store
