bdb 6.X was released under the AGPL, which is incompatible with MIT-licensed
software (the result must be licensed under AGPL). bdb 5.X uses the same license
as bdb 4.8, and thus retains the same compatibility as in upstream Bitcoin.
Thanks to Luke-Jr for raising this issue.
These flags are potentially risky, because they require that the app explicitly
initialize stuff that it wouldn't otherwise need to initialize, and we don't
have time for the necessary review.
In some cases, such as for github revision tarballs, the upstream
filename is just ``$HASH.tar.gz``, but the local filename is
``${PACKAGE_NAME}-${HASH}.tar.gz``. With this patch, it's clear which
packages each URLs provides *and* it makes the process of updating
http://z.cash/depends/sources a simple scp rather than involving some
kind of name translation.
Closes#622.
Some specifics on consensus changes:
* Transactions must be anchored to a real anchor in the chain.
* Anchors are pushed and popped during ConnectBlock/DisconnectBlock as appropriate.
* DisconnectTip triggers evictions, under some circumstances, of transactions in the
mempool which are anchored to roots that are no longer valid.
* Commitments append to the tree at the current best root during ConnectBlock.
This passes `-Wa,--noexecstack` to the assembler when building
platform-specific assembly files, to signal that a non-executable stack
can be used. This is the same approach as used by Debian
(see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=430583)

Boost assumes variadic templates are always available in GCC 4.4+, but
they aren't since we don't build with -std=c++11.
This applies the patch that fixed the issue in boost 1.57:

Documentation more readable when viewed on Github.
Some extra changes by @laanwj:
- Make README.usage the default README. This is more convenient from a
user perspective. Link to other documentation in this default README
- Add list of popular targets for cross compilation, change default to
Win64 instead of Win32
In some cases (Travis), sources and build caches may be moved around in-between
builds, and we can't necessarily trust that everything is still intact.
This introduces pre-build checks that verify against stashed checksums.
Note that this will cause all sources to be re-downloaded, since cached sources
weren't trustworthy before this.
See here for background: https://bugreports.qt.io/browse/QTBUG-34748
libxcb temporarily had an abi breakage which caused crashes when qt was
compiled against a non-compatible version. Building qt with -qt-xcb should have
shielded us from this issue, except that incompatible headers were used when
building qt's wrapper.
Make sure those headers aren't picked up by qt's build.
Details:
qt's build adds a wrapper around the xcb libs when -qt-xcb is used. This is
done to avoid having to link to a handful of different libs, which may not be
api/abi stable. This build depends on include-order, so that its files are
found before the real libxcb headers.
Our build (for other reasons related to qt's complicated build-system) injects
our prefix into CXXFLAGS. Because libxcb is found in this path, that reverses
the include-order, negating the purpose of the wrapper.
To fix, libxcb's includes are simply moved to a subdir. pkg-config ensures that
they're still found properly when needed.
To make things even more interesting, this behavior in qt's .pro files is broken:
INCLUDEPATH += $$QMAKE_CFLAGS_XCB
The INCLUDEPATH variable is processed by qmake which automatically prefixes each
entry with "-I". The QMAKE_CFLAGS_XCB variable comes from pkg-config and
already contains -I, making the path look like "-I-I/path/to/xcb/headers".
To work around that, CFLAGS/CXXFLAGS are used here rather than INCLUDEPATH.
