Instruct people to "git fetch" so that if this is their 2nd+ gitian build they will have a fresh bitcoin repo.
Instruct people to add all the known pgp keys to their keyring so that gverify will print more useful info.
These are changes I needed to get gitian building to work with Debian
8.2, which is the version we tell to use.
- Set up NAT, so that container can access network beyond host
- Remove explicit cgroup setup - these are mounted automatically now
- 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
Adds 127.0.0.1:9050 for the .onion proxy if we can succesfully connect
to the control port.
Natural followup to creating hidden services automatically.

Assume that when a wallet transaction has a valid block hash and transaction position
in it, the transaction is actually there. We're already trusting wallet data in a
much more fundamental way anyway.
To prevent backward compatibility issues, a new record is used for storing the
block locator in the wallet. Old wallets will see a wallet file synchronized up
to the genesis block, and rescan automatically.
done automatically.
At some point along the line, fully offline builds were no longer happening
when strictly following the release-process.md instructions.
We should ensure that users who might want to torify or build offline need
to take extra steps to remain offline.
Also, corrections to build process: including gverify examples for new builders.

This is an ideal version of what the release process should look like,
making it more consistent with the OS X process. Some of the changes
described here would need to be made in the descriptors, which is somewhat
beyond what I would feel comfortable doing, not really understanding the signature process in depth.
[skip ci]
Rather than fetching a signature.tar.gz from somewhere on the net, instruct
Gitian to use a signature from a tag in the bitcoin-detached-sigs repository
which corresponds to the tag of the release being built.
This changes detached-sig-apply.sh to take a dirname rather than a tarball as
an argument, though detached-sig-create.sh still outputs a tarball for
convenience.

- Split linux32/linux64 releases
- Split win32/win64 zips
- Post-processing should no longer be required. The deterministic outputs are
ready for consumption.
- switching release builds to 10.7
- release binary looks like 64bit only
- tested up to 10.10
- gitian builder builds against 10.7. The docs should be consistant.
- remove 32bit text because nowadays it's obvious to support 64bit only on OSX.
Start the RPC server before doing all the (expensive) startup
initialisations like loading the block index. Until the node is ready,
return all calls immediately with a new error signalling "in warmup"
with an appropriate status message (similar to the init message).
This is useful for RPC clients to know that the server is there (e. g.,
they don't have to start it) but not yet available. It is used in
Namecoin and Huntercoin already for some time, and there exists a UI
hooked onto the RPC interface that actively uses this to its advantage.
The homebrew instructions were outdated - berkeley-db4 hasn't worked for months, based on the questions I'm seeing on Google/SO. So I added a section explaining how to install berkeley-db4 using homebrew and move on with your life. Thanks for the rest of the documentation!
Bitcoin core should work with any remotely recent boost version
if a proper build environment is present. Remove a confusing comment
from the build documentation.
Anyone building bitcoind/-qt on windows is welcome to contribute
a new one. The current information in this document is outdated,
or otherwise mostly worthless.
The wallet now uses the mempool fee estimator with a new
command-line option: -txconfirmtarget (default: 1) instead
of using hard-coded fees or priorities.
A new bitcoind that hasn't seen enough transactions to estimate
will fall back to the old hard-coded minimum priority or
transaction fee.
-paytxfee option overrides -txconfirmtarget.
Relaying and mining code isn't changed.
For Qt, the coin control dialog now uses priority estimates to
label transaction priority (instead of hard-coded constants);
unspent outputs were consistently labeled with a much higher
priority than is justified by the free transactions actually
being accepted into blocks.
I did not implement any GUI for setting -txconfirmtarget; I would
suggest getting rid of the "Pay transaction fee" GUI and replace
it with either "target number of confirmations" or maybe
a "faster confirmation <--> lower fee" slider or select box.
This is PR #4271, but with the changes to the descriptors, both the names of the
files and the names of the intermediate build artifact archives, removed.
This also closes#3775 if it goes in, because it covers the changes in
that PR.
New RPC methods: return an estimate of the fee (or priority) a
transaction needs to be likely to confirm in a given number of
blocks.
Mike Hearn created the first version of this method for estimating fees.
It works as follows:
For transactions that took 1 to N (I picked N=25) blocks to confirm,
keep N buckets with at most 100 entries in each recording the
fees-per-kilobyte paid by those transactions.
(separate buckets are kept for transactions that confirmed because
they are high-priority)
The buckets are filled as blocks are found, and are saved/restored
in a new fee_estiamtes.dat file in the data directory.
A few variations on Mike's initial scheme:
To estimate the fee needed for a transaction to confirm in X buckets,
all of the samples in all of the buckets are used and a median of
all of the data is used to make the estimate. For example, imagine
25 buckets each containing the full 100 entries. Those 2,500 samples
are sorted, and the estimate of the fee needed to confirm in the very
next block is the 50'th-highest-fee-entry in that sorted list; the
estimate of the fee needed to confirm in the next two blocks is the
150'th-highest-fee-entry, etc.
That algorithm has the nice property that estimates of how much fee
you need to pay to get confirmed in block N will always be greater
than or equal to the estimate for block N+1. It would clearly be wrong
to say "pay 11 uBTC and you'll get confirmed in 3 blocks, but pay
12 uBTC and it will take LONGER".
A single block will not contribute more than 10 entries to any one
bucket, so a single miner and a large block cannot overwhelm
the estimates.
Upgrade for https://www.openssl.org/news/secadv_20140605.txt
Just in case - there is no vulnerability that affects ecdsa signing or
verification.
The MITM attack vulnerability (CVE-2014-0224) may have some effect on
our usage of SSL/TLS.
As long as payment requests are signed (which is the common case), usage
of the payment protocol should also not be affected.
The TLS usage in RPC may be at risk for MITM attacks. If you have
`-rpcssl` enabled, be sure to update OpenSSL as soon as possible.
1411a51 doc: Update hash in release process for new windows deps intermediate (Wladimir J. van der Laan)
386e732 gitian: make linux qt intermediate deterministic (Wladimir J. van der Laan)
I added a link to my guide about using docker containers + LXC (I am planning to maintain this at work
for future bitcoin versions), then I mentioned other virtualization options (KVM, LXC).
This commit includes a fix issue for documentation issue #4269 that consists in telling users to
checkout correct bitcoin version before using the gitian descriptors (otherwise all hell can break loose).
Also, I replaced URL for Debian 7.4 ISO with a correct one and added link to official Debian ISO sources.
A qt installation date snuck into the host utils (lrelease etc)
This doesn't affect the end product, so no dependency version bump.
It also doesn't explain why gavin's and mine build is different
There is no need to use any specific version of boost on Linux/Unix.
Even 1.37 should still work.

3ab1664 gitian: build against Qt 4.6 (Wladimir J. van der Laan)
The year is 2014. All supported operating systems have IPv6 support,
most certainly at build time (this doesn't mean that IPv6 is configured,
of course).
If noone is exercising the functionality to disable it, that means it
doesn't get tested, and IMO it's better to get rid of it.
(it's also not used consistently in RPC/boost and Net code...)
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
This is a project-wide configuration file and should be the same for
everyone.
Also remove mention of creating it yourself from the translation process.
- People were having problems with the .so when installing in
alternative locations.
Like gitian, build a static library with -fPIC that can
be embedded into the executables.
- Add some missing steps
- Add reminder that BerkeleyDB is only needed when wallet support is
enabled
Should make it possible to run the resulting GUI executable on
Linux distributions that use Qt 4.6, such as Debian Wheezy and Tails.
Builds a mini-SDK for building against Qt 4.6. This includes the headers
as well as host utilities such as `lrelease`, `qrc` and `moc`.
This speeds up the gitian build a bit - libqt4-dev pulled in a lot of packages,
and is no longer needed as this provides a replacement of our own.
Note: This does not replace the Qt build with at static library. After this
commit we still build dynamically against the system Qt library. The only
difference is that compatibility with an older version is maintained. This
loses minor GUI functionality (such as setPlaceholderText) but still
allows integration into the window management of the host OS, unlike
when statically linking.
The patch to make it possible to configure the LXC IPs has been merged
upstream. This means that it is no longer needed to patch gitian.
Remove that workaround.
Drawback: The version string is no longer a valid git identifier.
For this reason the 'g' short hash prefix has been removed.
Exception: When building directly from a tag this behaves exactly like the previous behavior.
This allows formatting release versions with precision i.e. v0.9.2
This also allows arbitrary topicbranch names i.e. v0.9.1-glibc-compat

Bumps deps-linux, deps-win dependency versions as well.
qt-win does not need to be bumped, as although it depends on deps-win,
Qt doesn't use miniupnp. I verified this by rebuilding the dependency
and checking the the output is the same. Not having to rebuild Qt is a
good thing as it is huge.

Use a series of .png frames for the spinner instead of a .mng.
`mng` is an obscure image format and is not built by default into Qt5.
This appears to improve the crispness of the spinner as well.
Does not noticably increase the size (still ~27k) and the code
is not more complicated either.
- remove unused and unmentioned file notsynced.png (we use an animation
for this)
- add missing coincontroldialog.ui to bitcoin-qt.pro
- also unify formating in assets-attribution.md

- es_MX: Spanish (Mexico)
- pam: Kapampangan
Also update translation process for autoconf-based build system.
Only messages for now, executable names and other file names
can be changed later if necessary and safe.
Do not do an all-sweeping change. Some occurences of Bitcoin-Qt need to
be kept:
- Applicationname: this is used to determine the registry entry names,
we don't want to lose settings over a silly name change.
- Where it refers to the executable name instead of the product name.

I was merging change this every time before generation of

but there's no reason why it can't just be merged upstream.
Selecting the button for a pages was going through bitcoingui->walletframe->walletview->bitcoingui.
Because of this, the actions for the pages had to be exposed on the BitcoinGUI object.
Seems like there are a lot of advertised testnet HS nodes that

This commit adds a step, which is to git checkout the version to be

the correct ones. In addition, it updates the links for several
dependencies, where the previously existing links were dead.

This commit also demonstrates a method to verify the integrity of inputs.
I've seen users confused multiple times thinking they
should be using -tor to set their tor proxy and then
finding in horror that they were still connecting to
the IPv4 internet.
Even Jeff guesses wrong about what the knob does, so
I think we should rename it. This leaves the old
knob working, we can pull it out completely in a
later release.
Add support for a Payment Protocol to Bitcoin-Qt.
Payment messages are protocol-buffer encoded and communicated over
http(s), so this adds a dependency on the Google protocol buffer
library, and requires Qt with OpenSSL support.
This commit squashes all the changes in the Qt5 branch
relative to master.
Backward compatibility with Qt4 is retained.

Set CLIENT_VERSION_IS_RELEASE to remove pre-release warning
Updated copyright in COPYING and doc/READMEs to 2013
Updated doc/release-notes.txt
Use 'osascript' to run AppleScript, instead of using (broken-in-10.8)
python appscript package.
And added support for code-signing the .app bundle, to make OSX's
GateKeeper happy.
Implements #1948
- Add macro `CLIENT_VERSION_IS_RELEASE` to clientversion.h
- When running a prerelease (the above macro is `false`):
- In UI, show an orange warning bar at the top. This will be used for other
warnings (and alerts) as well, instead of the status bar.
- For `bitcoind`, show the warning in the "errors" field in `getinfo`
response.
This reverts commit 199d88cf90, reversing
changes made to 65bc1573e7.
License is worse instead of better. Will only accept public domain and
MIT-licensed icons from now on.
- add version information to bitcoin-qt.rc, which is displayed on Windows, when looking in the executable properties and selecting "Details"
- introduce a new clientversion.h (used in bitcoin-qt.rc to generate
version information), which takes only the version defines from
version.h and is included in it (to allow usage with the windres rc-file
compiler)
- move #define STRINGIFY(s) #s into clientversion.h as that is used in
bitcoin-qt.rc and rename to DO_STRINGIZE(X)
- add #define STRINGIZE(X) DO_STRINGIZE(X), which is needed to convert the
version defines into a version string in the rc-file
- this ensures we only need to update 1 file and have bitcoin-qt.exe
version information
- for RC-file documentation see:
http://msdn.microsoft.com/en-us/library/windows/desktop/aa381058%28v=vs.85%29.aspx
This will make bitcoin relay valid routable IPv6 addresses, and when
USE_IPV6 is enabled, listen on IPv6 interfaces and attempt connections
to IPv6 addresses.
All client version information is moved to version.cpp, which optionally
(-DHAVE_BUILD_INFO) includes build.h. build.h is automatically generated
on supporting platforms via contrib/genbuild.sh, using git describe.
The git export-subst attribute is used to put the commit id statically
in version.cpp inside generated archives, and this value is used if no
build.h is present.
The gitian descriptors are modified to use git archive instead of a
copy, to create the src/ directory in the output. This way,
src/src/version.cpp will contain the static commit id. To prevent
gitian builds from getting the "-dirty" marker in their git-describe
generated identifiers, no touching of files or running sed on the
makefile is performed anymore. This does not seem to influence
determinism.
