526e28220a contrib: Add support for out-of-tree builds in gen-manpages.sh (Wladimir J. van der Laan)
Pull request description:
This adds support for setting the environment variable `BUILDDIR` to point to executables that are outside the source directory.
E.g. to invoke the tool when the build is in $PWD/build:
```bash
BUILDDIR=$PWD/build contrib/devtools/gen-manpages.sh
```
This avoids having to manually copy the generated manpages after they end up in the build instead of source path, when setting TOPDIR instead.

Pull request description:
Changes:
* Add note about test suite naming convention
* Fix exceptions
* Add regression test
Rationale:
* Consistent naming of test suites makes programmatic test running of specific tests/subsets of tests easier
* Explicit is better than implicit
Before this commit:
```
$ contrib/devtools/lint-tests.sh
The test suite in file src/test/foo_tests.cpp should be named
"foo_tests". Please make sure the following test suites follow
that convention:
src/test/blockchain_tests.cpp:BOOST_FIXTURE_TEST_SUITE(blockchain_difficulty_tests, BasicTestingSetup)
src/test/prevector_tests.cpp:BOOST_FIXTURE_TEST_SUITE(PrevectorTests, TestingSetup)
src/wallet/test/coinselector_tests.cpp:BOOST_FIXTURE_TEST_SUITE(coin_selection_tests, WalletTestingSetup)
src/wallet/test/crypto_tests.cpp:BOOST_FIXTURE_TEST_SUITE(wallet_crypto, BasicTestingSetup)
$
```
After this commit:

77aa9e59e test: Check RPC argument mapping (Wladimir J. van der Laan)
Pull request description:
Parse the dispatch tables from the server implementation files, and the conversion table from the client (see #10751).
Perform the following consistency checks:
- Arguments defined in conversion table, must be present in dispatch table. If not, it was probably forgotten to add them to the dispatch table, and they will not work.
- Arguments defined in conversion table must have the same names as in the dispatch table. If not, they will not work.
- All aliases for an argument must either be present in the conversion table, or not. Anything in between means an oversight and some aliases won't work.
Any of these results in an error.
It also performs a consistency check to see if the same named argument is sometimes converted, and sometimes not. E.g. one RPC call might have a 'verbose' argument that is converted,
another RPC call might have one that is not converted. This is not necessarily wrong, but points at a possible error (as well as makes the API harder to memorize) - so it is emitted as a warning (could upgrade this to error).
This test is added to travis and run when `CHECK_DOC`. Currently fails with the following output:
```
* Checking consistency between dispatch tables and vRPCConvertParams
ERROR: createrawtransaction argument 3 (named optintorbf in vRPCConvertParams) is not defined in dispatch table
ERROR: getblock argument ['verbosity', 'verbose'] has conflicts in vRPCConvertParams conversion specifier [True, False]
WARNING: conversion mismatch for argument named verbose ([('getblock', False), ('getblockheader', True), ('getmempoolancestors', True), ('getmempooldescendants', True), ('getrawmempool', True), ('getrawtransaction', True)])
```
- ~#10698 fixes the first ERROR~
- #10747 fixes the second ERROR, as well as the WARNING
Update: #10698 was merged, leaving:
```

There is often some context given in PR descriptions that is missing from commits, and it may be worthwhile to retain that information in our history in git. This PR adds that information to the merge commit when created through `github-merge.py`.
We should also encourage people to provide as much information as possible in the PR commits themselves, but I believe that is an orthogonal issue. Individual commits don't need to have a description of the overall goal of a PR.

These are not added to the default checks because some of them depend on
release-build configs.
- always link librt for glibc back-compat builds
glibc absorbed clock_gettime in 2.17. librt (its previous location) is safe to
link in anyway for back-compat.
Fixes#7420
- add security/symbol checks to gitian
Github-Pull: #7424
Rebased-From: cd27bf51e0475813ba5bf3d3eaf78ea8ce872118a81c87fafc
- Add new translations (finally, after a long time)
- update-translation script was not considering new translations - oops
- fixed this, also remove (nearly) empty translations
- Update translation process, it was still describing the old repository
structure
Perform the following ELF security checks:
- PIE: Check for position independent executable (PIE), allowing for address space randomization
- NX: Check that no sections are writable and executable (including the stack)
- RELRO: Check for read-only relocations, binding at startup
- Canary: Check for use of stack canary
Also add a check to symbol-check.py that checks that only the subset of
allowed libraries is imported (to avoid incompatibilities).
This reverts commit 1078fb0885 (and thus
pull #5623). It has various issues:
- Pull request names get cut off at ", see e.g. a026a56
- Merge script no longer copes with pulls that have a milestone
attached, due to a duplicate 'title' in JSON that is not handled by the
ad-hoc parsing.
- Check that image contents match pre- and post- crushing.
- Also remove use of external tool to compute sha256 in favor of hashlib.
- contrib: remove all use of shell=True in strip_pngs.py
Using `shell=True` can be a security hazard. See e.g.
https://docs.python.org/2/library/subprocess.html#subprocess.check_output
- Catch problems such as mismatched formatting characters. Remove
messages that can give problems at runtime.
- Also remove unfinished/untranslated messages, they just take up space
in the ts and waste parsing time.
Fixes#4774.

Running git version 2.1.0 on OSX (homebrew), I get
fatal: '1q': not a non-negative integer
I'm guessing git command-line parsing got more strict recently?
3a54ad9 Full translation update (Wladimir J. van der Laan)
9dd5d79 devtools: add a script to fetch and postprocess translations (Wladimir J. van der Laan)
58c01a3 qt: add transifex configuration file (Wladimir J. van der Laan)
Run this script from the root of the repository to update all translations from transifex.
It will do the following automatically:
- create a transifex configuration file
- fetch all translations
- post-process them into valid and committable format
Add a script to check that the (Linux) executables produced by gitian
only contain allowed gcc, glibc and libstdc++ version symbols. This
makes sure they are still compatible with the minimum supported Linux
distribution versions.
contrib/devtools/fix-copyright-headers.py script to be able to perform this maintenance task with ease during the rest of the year, every year. Modifications to contrib/devtools/README.md to document what fix-copyright-headers.py does.
