      relicense LGPL-2.1 code as LGPL-2.1 or LGPL-3.0 · 2f361a6e
      Sage Weil authored 
      
The primary motivation to relicense is a desire to integrate with projects
that are licensed under the Apache License version 2.0.  Although opinions
vary, there are some who argue the the LGPL-2.1 and Apache-2.0 licenses
are not fully compatible.  We would like to avoid the ambiguity and
potential for controversy.

Projects we would like to consume that are Apache-2.0 licensed include
Seastar, OpenSSL (which is in the process of relicensing to Apache-2.0),
and Swagger (swagger.io).  Note that some of these are dynamically linked
or consumed via a high-level language and may or may not require a change
to LGPL-3.0, but providing the option for LGPL-3.0 certainly avoids any
uncertainty.

A few other source files are already incorporated into Ceph that claim an
Apache-2.0 license:

    src/common/deleter.h
    src/common/sstring.h
    src/include/cpp-btree

The Ceph developers would further like to provide a license option that is
more modern than the current LGPL-2.1.  LGPL-3.0 includes updated,
clarified language around several issues and is widely considered
more modern, superior license.

      legal: remove doc license ambiguity · e294dd59
      Nathan Cutler authored 
      The license applicable to the files under doc/ was originally declared (in the
top-level file COPYING) to be "Creative Commons Attribution-ShareAlike (CC
BY-SA)" by ed0653b4

This license declaration omitted a version number.

Some time later ef741842 was merged, mentioning
CC-BY-SA-1.0 as one of the Ceph source code licenses. Although the purpose of that
commit was only to summarize the canonical license information from COPYING, it
unintentionally became the only place in the source code where the doc license
version was specified.

In March 2018, the Debian project warned that CC-BY-SA-1.0 does not meet its
criteria for inclusion in the "free" section of the Debian distribution. (For
that, at least version 3.0 must be used.)

This new commit removes the doc license ambiguity by setting it to CC-BY-SA-3.0
in all places where the license is mentioned.

The exact spelling of the license name is taken from https://spdx.org/licenses/

Fixes: http://tracker.ceph.com/issues/23336

      Unit tests for chain_xattr.cc · a62d5198
      Loic Dachary authored 
      Create a new test file covering most (> 97%) of src/os/chain_xattr.{cc,h}
lines of code. The following functions are tested:

int chain_getxattr(const char *fn, const char *name, void *val, size_t size);
int chain_fgetxattr(int fd, const char *name, void *val, size_t size);
int chain_setxattr(const char *fn, const char *name, const void *val, size_t size);
int chain_fsetxattr(int fd, const char *name, const void *val, size_t size);
int chain_listxattr(const char *fn, char *names, size_t len);
int chain_flistxattr(int fd, char *names, size_t len);
int chain_removexattr(const char *fn, const char *name);
int chain_fremovexattr(int fd, const char *name);

The function translate_raw_name substitutes @@ into @. When the trailing
character is a @, it breaks. However, such an occurence cannot be created by
chain_setxattr because it always create pairs of @. Instead of silently
breaking the loop, the function should probably return on error so that the
caller can ignore it.

The function chain_fgetxattr_len may return on error if fgetxattr
returns on error. However, it is only called after another attr function
returned success and the tests cannot create the conditions under which
it would fail.

The function chain_fsetxattr may leak attributes when used to override
an existing attribute. This leak is not tested or fixed, it is just
discussed in http://marc.info/?l=ceph-devel&m=136027076615853&w=4

If the file system in which the tests are run does not support extended
attributes, the tests are not run. The detection uses the same logic as
the one implemented in FileStore::_detect_fs

The output of the tests are silenced to reduce the output when testing
assertions ( except for the dout_emergency function which cannot be
controlled).

      Relax Throttle::_reset_max conditions and associated unit tests · 64ded02c
      Loic Dachary authored 
      
Removes a condition in Throttle::_reset_max by which the waiting queue is only
Signal()ed if the new maximum is lower than the current maximum.
There is no evidence of a use case where such a restriction would be
useful. In addition waking up a thread when the maximum increases
gives it a chance to immediately continue the suspended process
instead of waiting for the next put().

Create a new test file covering 100% of src/Throttle.{cc,h} lines of code.
The following methods are tested:

* Throttle::Throttle with and without a maximum
* Throttle::~Throttle when each pending Cond is deleted
* Throttle::take
* Throttle::get when updating the maximum ( lower or higher ),
  when going to sleep waiting for the count to lower under
  the maximum, when going to sleep because another thread is
  already asleep waiting
* Throttle::get_or_fail when there is no maximum,
  when requesting a count that is larger than the maximum, either
  when the current value is under the maximum or above the maximum.
* Throttle::wait when used to reset the maximum and wake up
  another thread asleep waiting

All asserts checking the arguments sanity are exercised ( negative argument
for Throttle::take etc. ).
Adds the LGPLv2+ licensing terms to COPYING along with the others.
Adds a Contributors section to the AUTHORS file.

Notes:
Testing asserts outputs verbose error messages that should be silenced
but it does not seem possible.

      Sage Weil authored 
      
This is lightweight and relies on boost spirit, which we already use, so
there are no new dependencies.

There were some other libraries that also looked good, but they weren't
already packages for existing Debian distros like squeeze or even wheezy.
