Ceph is a distributed object, block, and file storage platform
fa77e1e732
Instead of allowing services to directly use 'propose_pending()' on
other services, we instead add two new functions:
- request_proposal() to request 'this' service to propose its
pending value; and
- request_proposal(PaxosService *other) so that 'this' service
can request a proposal to 'other'
These functions should allow us to enforce a greater set of
constraints at time of a cross-proposal, either by making sure a
service will (e.g.) hold-off his own proposals until said proposal
is performed, or even that the other service will enforce a tighter
set of constraints that wouldn't otherwise be enforced by using
'propose_pending()' directly.

============================================ Ceph - a scalable distributed storage system ============================================ Please see http://ceph.com/ for current info. Contributing Code ================= Most of Ceph is licensed under the LGPL version 2.1. Some miscellaneous code is under BSD-style license or is public domain. The documentation is licensed under Creative Commons Attribution-ShareAlike (CC BY-SA). There are a handful of headers included here that are licensed under the GPL. Please see the file COPYING for a full inventory of licenses by file. Code contributions must include a valid "Signed-off-by" acknowledging the license for the modified or contributed file. Please see the file SubmittingPatches for details on what that means and on how to generate and submit patches. We do not require assignment of copyright to contribute code; code is contributed under the terms of the applicable license. Building Ceph ============= To prepare the source tree after it has been git cloned, $ git submodule update --init To build the server daemons, and FUSE client, execute the following: $ ./autogen.sh $ ./configure $ make (Note that the FUSE client will only be built if libfuse is present.) Dependencies ------------ The configure script will complain about any missing dependencies as it goes. You can also refer to debian/control or ceph.spec.in for the package build dependencies on those platforms. In many cases, dependencies can be avoided with --with-foo or --without-bar switches. For example, $ ./configure --with-nss # use libnss instead of libcrypto++ $ ./configure --without-radosgw # do not build radosgw and avoid libfcgi-dev $ ./configure --without-tcmalloc # avoid google-perftools dependency Building packages ----------------- You can build packages for Debian or Debian-derived (e.g., Ubuntu) systems with $ sudo apt-get dpkg-dev $ dpkg-checkbuilddeps # make sure we have all dependencies $ dpkg-buildpackage For RPM-based systems (Redhat, Suse, etc.), $ rpmbuild Building the Documentation ========================== Prerequisites ------------- To build the documentation, you must install the following: - python-dev - python-pip - python-virualenv - doxygen - ditaa - libxml2-dev - libxslt-dev - dot - graphviz For example: sudo apt-get install python-dev python-pip python-virualenv doxygen ditaa libxml2-dev libxslt-dev dot graphviz Building the Documentation -------------------------- To build the documentation, ensure that you are in the top-level `/ceph directory, and execute the build script. For example: $ admin/build-doc Build Prerequisites ------------------- To build the source code, you must install the following: - automake - autoconf - gcc - g++ - libboost-dev - libedit-dev - libssl-dev - libtool - libfcgi - libfcgi-dev - libfuse-dev - linux-kernel-headers - libcrypto++-dev - libaio-dev - libgoogle-perftools-dev - libkeyutils-dev - uuid-dev - libatomic-ops-dev - libboost-program-options-dev - libboost-thread-dev - libexpat1-dev - libleveldb-dev - libsnappy-dev For example: $ apt-get install automake autoconf gcc g++ libboost-dev libedit-dev libssl-dev libtool libfcgi libfcgi-dev libfuse-dev linux-kernel-headers libcrypto++-dev libaio-dev libgoogle-perftools-dev libkeyutils-dev uuid-dev libatomic-ops-dev libboost-program-options-dev libboost-thread-dev libexpat1-dev libleveldb-dev libsnappy-dev
