I've written a script that automates the setup and building of binaries with gitian. All of the commands are pulled from various documentation on gitian building.
C_INCLUDE_PATH and CPLUS_INCLUDE_PATH work globally as though -isystem was used
for each invocation.
Since that changes the build results, force a rebuild of x86 depends by adding
the value to $HOST_ID_SALT.
* separate completion for bitcoind and bitcoin-cli
* remove RPC support from bitcoind completion
* add completion for bitcoin-tx and bitcoin-qt
* rely on autoloading of completions
Now that the trusted root is past all commits signed by that key we don't need
it in the trusted-keys list, nor do we need to whitelist those commits in
allow-revsig-commits
- create a script to handle split debug. This will also eventually need to check
targets, and use dsymutil for osx.
- update config.guess/config.sub for bdb for aarch64.
- temporarily disable symbol checks for arm/aarch64
- quit renaming to linux32/linux64 and use the host directly
This also adds a hack to work around an Ubuntu bug in the gcc-multilib package:
https://bugs.launchpad.net/ubuntu/+source/gcc-defaults-armhf-cross/+bug/1347820
The problem is that gcc-multilib conflicts with the aarch toolchain.
gcc-multilib installs a symlink that points
/usr/include/asm -> /usr/include/x86_64-linux-gnu/asm.
Without this link, gcc -m32 can't find asm/errno.h (and others), since
/usr/include/x86_64-linux-gnu isn't in its default include path. But
/usr/include/i386-linux-gnu is (though it doesn't exist on disk).
So work around the problem by linking
/usr/include/i386-linux-gnu/asm -> /usr/include/x86_64-linux-gnu/asm.
The symlink fix is actually quite reasonable, but echoing the password into
sudo is nasty, and should probably be addressed in gitian itself. It makes more
sense to enable passwordless sudo for the build user by default.
The -debug tarballs/zips contain detached debugging symbols. To use them, place
in the same dir as the target binary, and invoke gdb as usual.
Also, because the debug symbols add a substantial space requirement, the build
dirs are now deleted when they're no longer needed.
Any attacker who managed to make an evil commit that changed something in the
contrib/verify-commits/ directory could just as easily remove the warning
and/or modify it to not display the evil commits; telling the user to check
those commits specifically misleads them into checking just those commits
rather than the script itself.
This removes the following executables from the binary gitian release:
- test_bitcoin-qt[.exe]
- bench_bitcoin[.exe]
@jonasschnelli and me discussed this on IRC a few days ago - unlike the
normal `bitcoin_tests` which is useful to see if it is safe to run
bitcoin on a certain OS/environment combination, there is no good reason
to include these. Better to leave them out to reduce the download
size.
Sizes from the 0.12 release:
```
2.4M bitcoin-0.12.0/bin/bench_bitcoin.exe
22M bitcoin-0.12.0/bin/test_bitcoin-qt.exe
```
As we are already using the API to retrieve the pull request
title, also retrieve the base branch.
This makes sure that pull requests for 0.12 automatically end up in
0.12, and pull requests for master automatically end up in master,
and so on.
It is still possible to override the branch from the command line
or using the `githubmerge.branch` git option.
Ubuntu 16.04 "xenial xerus" does not come with Python 2.x by default.
It is possible to install a python-2.7 package, but this has its own
problem: no `python` or `python2` symlink (see #7717).
This fixes the following scripts to work with python 3:
- `make check` (bctest,py, bitcoin-util-test.py)
- `make translate` (extract_strings_qt.py)
- `make symbols-check` (symbol-check.py)
- `make security-check` (security-check.py)
Explicitly call the python commands using $(PYTHON) instead
of relying on the interpreter line at the top of the scripts.
This makes github-merge.py the first developer tool to go
all Python 3 (for context see #7717).
The changes are straightforward as the script already was
`from __future__ import division,print_function,unicode_literals`.
However urllib2 changed name, and json will only accept unicode data not
bytes.
This retains py2 compatibility for now: not strictly necessary
as it's not used by the build system - but it was easy.
