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.
Corrupt wallets used to cause a DB_RUNRECOVERY uncaught exception and a
crash. This commit does three things:
1) Runs a BDB verify early in the startup process, and if there is a
low-level problem with the database:
+ Moves the bad wallet.dat to wallet.timestamp.bak
+ Runs a 'salvage' operation to get key/value pairs, and
writes them to a new wallet.dat
+ Continues with startup.
2) Much more tolerant of serialization errors. All errors in deserialization
are reported by tolerated EXCEPT for errors related to reading keypairs
or master key records-- those are reported and then shut down, so the user
can get help (or recover from a backup).
3) Adds a new -salvagewallet option, which:
+ Moves the wallet.dat to wallet.timestamp.bak
+ extracts ONLY keypairs and master keys into a new wallet.dat
+ soft-sets -rescan, to recreate transaction history
This was tested by randomly corrupting testnet wallets using a little
python script I wrote (https://gist.github.com/3812689)
Before, opening a -datadir that was created with a new
version of Berkeley DB would result in an un-caught DB_RUNRECOVERY
exception.
After these changes, the error is caught and the user is told
that there is a problem and is told how to try to recover from
it.

- don't rely on the QSettings for cases ProxyUse and ProxySocksVersion and
query the real values via the GetProxy() call
- add a missing "succesful =" for case ProxyUse in ::setData()
I2P apparently needs 256 bits to store a fully routable address. Garlicat
requires a centralized lookup service to map the 80-bit addresses to fully
routable ones (as far as I understood), so that's not really usable in our
situation.
To support I2P routing and peer exchange for it, another solution is needed.
This will most likely imply a network protocol change, and extension of the
'addr' message.
- fix#1560 by properly locking proxy related data-structures
- update GetProxy() and introduce GetNameProxy() to be able to use a
thread-safe local copy from proxyInfo and nameproxyInfo
- update usage of GetProxy() all over the source to match the new
behaviour, as it now fills a full proxyType object
- rename GetNameProxy() into HaveNameProxy() to be more clear
This allows fun stuff such as `bitcoin --help | less`, and more
easy piping to files.
Looking at other tools such as bash, gcc, they all send their help
text to stdout.
These command are a leftover from send-to-IP transactions, which have been
removed a long time ago.
Also removes CNode::mapRequests and CNode::PushRequests, as these were
only used for the mentioned commands.
As the code was before, toHTML added empty elements to mapValue to check for their existance. Now first it check for their existance and then for their non-emptiness.
Removed a duplicated identical if
There are two equal ifs, one inside another. If the first one is true, then the second one is true.
Due to a bug in the implementation of MakeSameSize(), using OP_AND, OP_OR, or OP_XOR with signed values of unequal size will result in the sign-value becoming part of the smaller integer, with nonsensical results. This patch documents the unexpected behavior and provides the basis of a solution should decision be made to fix the bug in the future.
-detachdb option. Useful for upgrading, for example. Lets you use fast stops usually, but force a detach when needed. Also, allows
you to do a fast stop in a system normally configured for fast stops.
- I checked every occurance of strprintf() in the code and used %u, where
unsigned vars are used
- the change to GetByte() was made, as ip is an unsigned char
Matt pointed out some time ago that there existed a minor DOS
attack where a node in its initial block download could be wedged
by an overwrite attack in a fork created between checkpoints before
a time where BIP30 was enforced. Now that the BIP30 timestamp
is irreversibly past the check can be more aggressive and apply to
all blocks except the two historic violations.
- Paging using PageUp / PageDown now works when entry widget has focus
- Typing or pasting while the messages widget has focus auto-selects entry widget
We're in a wholly different world now, C++-compiler-wise.
Current std::stringstream implementations don't have the stated problem anymore,
and are just as fast as CDataStream.
The #ifdef'd block does not even compile anymore; CDataStream constructor changed,
and missing some std::. Also timing in whole seconds is also way too granular
to say anything sensible in such microbenchmarks. Just remove it,
it can always be found again in git history.

- 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

OrderedTxItems returns a multimap of pointers, but needs a place to store the actual CAccountingEntries it points to.
It had been using a stack item, which was clobbered as soon as it returned, resulting in undefined behaviour.
This fixes at least bug #1768.
Try to display a nicer message instead of dumping raw JSON object when possible. If the error
somehow doesn't have the required 'code' and 'message' fields, fall back to printing raw JSON object.
- re-order Qt Actions and connect() calls to match the real GUI layout,
which makes things easier to read and understand
- remove signMessageAction and verifyMessageAction from tabGroup as we
didn't use them anyway (as tooltips are not displayed in the menu remove
these too)
- update 2 comments
- be clear we don't "Show/Hide Bitcoins", but just the client window
- remove the tooltip for toggleHideAction as this is not shown anyway
- update a comment to be more general
If our IRC nick is in use (because some other node thinks it has
the same address we think we have) don't fruitlessly try to reconnect
using that name forever. After three tries, give up and use a random
nick. Either we'll learn a new local address from IRC and switch
to that, or it was right and the other guy is advertising for us.
This avoids a pessimal case where a second testnet node behind
a nat is unable to get any peers because he can't get on IRC.
Previously Bitcoin would refuse to use IRC if it was either not
accepting inbound connections or not making outbound. Instead this
changes it to not use IRC only if it's not doing either or if
IPv4 is off completely. If Bitcoin is not listening this will use
the default random nicks rather than the IP based ones.
Hard-code a special nId=max int alert, to be broadcast if the
alert key is ever compromised. It applies to all versions, never
expires, cancels all previous alerts, and has a fixed message:
URGENT: Alert key compromised, upgrade required
Variations are not allowed (ignored), so an attacker with
the private key cannot broadcast empty-message nId=max alerts.
This fixes two alert system vulnerabilities found by
Sergio Lerner; you could send peers unlimited numbers
of invalid alert message to try to either fill up their
debug.log with messages and/or keep their CPU busy
checking signatures.
Fixed by disconnecting/banning peers if they send 10 or more
bad (invalid/expired/cancelled) alerts.
Windows & WindowsXP style have a problem with displaying the block progress.
Add a custom stylesheet as workaround, but only when one of those renderers is active,
otherwise leave the theme alone (issue #1071).
- add a new label, which can be updated independently from the whole
license information stuff
- the benefit is, we don't need to re-translate that whole wall of text
every year the copyright info changes
- update to the same copyright string we use in the source and in the
bitcoin-qt.exe meta-data information
- removes an obsolete entry from the ui-file
- Show address receiving the generation, and include it in the correct "account"
- Multiple entries in listtransactions output if the coinbase has multiple outputs to us
This applies on top of the coincontrol listaddressgroupings patch
and makes finding eligible outputs from the groups returned
by listaddressgroupings possible.
Logic:
- If sending a transaction, assign its timestamp to the current time.
- If receiving a transaction outside a block, assign its timestamp to the current time.
- If receiving a block with a future timestamp, assign all its (not already known) transactions' timestamps to the current time.
- If receiving a block with a past timestamp, before the most recent known transaction (that we care about), assign all its (not already known) transactions' timestamps to the same timestamp as that most-recent-known transaction.
- If receiving a block with a past timestamp, but after the most recent known transaction, assign all its (not already known) transactions' timestamps to the block time.
For backward compatibility, new accounting data is stored after a \0 in the comment string.
This way, old versions and third-party software should load and store them, but all actual use (listtransactions, for example) ignores it.
Replace direct calls to mlock.
Also, change the class to lock the memory areas in the constructor and unlock them again in the destructor. This makes sure that locked pages won't leak.
Memory locks do not stack, that is, pages which have been locked several times by calls to mlock()
will be unlocked by a single call to munlock(). This can result in keying material ending up in swap when
those functions are used naively. In this commit a class "LockedPageManager" is added
that simulates stacking memory locks by keeping a counter per page.
Allows the user to pass null as the second or third parameter
to signrawtransaction, in case you need to (for example) fetch
private keys from the wallet but want to specify the hash type.
This does two things:
1) Now does not output to debug.log if -printtodebugger flag is passed
2) Unit tests set -printtodebugger so only test results are output to stdout
Note that -printtodebugger only actually prints to the debugger on Windows.
If 950 of the last 1,000 blocks are nVersion=2, reject nVersion=1
(or zero, but no bitcoin release has created block.nVersion=0) blocks
-- 75 of last 100 on testnet3.
This rule is being put in place now so that we don't have to go
through another "express support" process to get what we really
want, which is for every single new block to include the block height
in the coinbase.
"Version 2" blocks are blocks that have nVersion=2 and
have the block height as the first item in their coinbase.
Block-height-in-the-coinbase is strictly enforced when
version=2 blocks are a supermajority in the block chain
(750 of the last 1,000 blocks on main net, 51 of 100 for
testnet). This does not affect old clients/miners at all,
which will continue producing nVersion=1 blocks, and
which will continue to be valid.
- extend bitcoin-qt.rc to include meta information, which is displayed on
Windows, when looking in the executable properties and selecting
"Details"
- does currently NOT include version information, this is scheduled
for later releases

This is the last time for 0.7.0. We should avoid message changes
until the release. Translators can use the remaining time to update their languages on
Transifex.
The other languages need to be merged from Transifex just before release.
Signrawtransaction rpc was crashing when some inputs were unknown,
and even with that fixed was failing to handle all the known inputs
if there were unknown inputs in front of them. This commit instead
attempts to fetch inputs one at a time.
- this enables DEP on all Windows version which support the
SetProcessDEPPolicy() call in Kernel32.dll
- use a dynamic approach via GetProcAddress() to not rely on headers or
compiler libs
- this is the same way the Tor-project does it
- add enableApplyButton() and disableApplyButton() to optionsdialog.{h/cpp}
- they are used to ensure the Ok button does not get disabled, when Apply needs to be disabled (standard UX should allow Ok always to dismiss the dialog and only disable it, when we have a faulty proxy IP)
- disable Apply after initially loading the settings, as nothing new needs to be saved
- remove orphan settings from optionsdialog.ui that are default anyway
- If the height is in the first half, start at the genesis block and go up, rather than at the top
- Cache the last lookup and use it as a reference point if it's close to the next request, to make linear lookups always fast
- ensure warnings always start with "Warning:" and that the first
character after ":" is written uppercase
- ensure the first sentence in warnings ends with an "!"
- remove unneeded spaces from Warning-strings
- add missing Warning-string translation
- remove a "\n" and replace with untranslatable "<br><br>"
- place "-?" option at first
- re-work description and "\n" usage for Gavins new block creation options
to better match current description syntax
- ensure no "\n" is in translated strings, which is better for Transifex
The new bytes are based on "11" to appeal to Gavin's 11 fetish.
This breaks existing testnet3 nodes as the blockchain files
are also versioned. To upgrade a node delete everything
except wallet.dat from your .bitcoin/testnet3 folder.
Modify CreateNewBlock so that instead of processing all transactions
in priority order, process the first 27K of transactions in
priority order and then process the rest in fee-per-kilobyte
order.
This is the first, minimal step towards better a better fee-handling
system for both miners and end-users; this patch should be easy
to backport to the old versions of Bitcoin, and accomplishes the
most important goal-- allow users to "buy their way in" to blocks
using transaction fees.
- remove duplicate includes, that are already present in ui_optionsdialog.h
- change QIntValidator to not allow 0 as port-number
- re-order some function calls to match the Ui element order, for better readbility and to prepare for the addition of further IPv6 and Tor proxy options
- restat warning for the language selection is only shown, when the language was changed (not on simply activating the Ui element)
- split check for object == ui->proxyIp into seperate if-clause
- micro-optimize the code in the above mentioned if-clause
- unify used format for comments in the code
- introduce handleProxyIpValid() function, which handles UI elements and the
save button states for valid/invalid proxy IPs
- add IMPLEMENT_RANDOMIZE_STACK for ipcThread()
- log / print boost interprocess exceptions
- use MAX_URI_LENGTH in guiconstants.h (also used in qrcodedialog.cpp)
- remove unneeded includes and ipcShutdown() from qtipcserver.cpp
- fix a small mem-leak by deleting mq before re-using it
- make ipcThread() and ipcThread2() static functions
- add some more comments
NOTE: This is currently disabled, until a developer with FreeBSD/OpenBSD
can confirm that this works (without causing undefined behaviour
preferrably).
