The Database, DatabaseWidget, and DatabaseTabWidget classes share many responsibilities in inconsistent ways resulting in impenetrable and unmaintainable code and a diverse set of bugs and architecture restrictions. This patch reworks the architecture, responsibilities of, and dependencies between these classes.
The core changes are:
* Move loading and saving logic from widgets into the Database class
* Get rid of the DatabaseManagerStruct and move all the information contained in it into the Database
* Let database objects keep track of modifications and dirty/clean state instead of handing this to external widgets
* Move GUI interactions for loading and saving from the DatabaseTabWidget into the DatabaseWidget (resolves#2494 as a side-effect)
* Heavily clean up DatabaseTabWidget and degrade it to a slightly glorified QTabWidget
* Use QSharedPointers for all Database objects
* Remove the modifiedImmediate signal and replace it with a markAsModified() method
* Implement proper tabName() method instead of reading back titles from GUI widgets (resolves#1389 and its duplicates #2146#855)
* Fix unwanted AES-KDF downgrade if database uses Argon2 and has CustomData
* Improve code
This patch is also the first major step towards solving issues #476 and #2322.
* Support ! modifier (same as '-')
* Create reusable PopupHelpWidget as self-contained popup that can
be positioned around a parent widget and will follow the movement
and sizing of the window
* Eliminated KEEPASSXC_MAIN_WINDOW macro and replaced with
getMainWindow() function
* Add tests to cover search help show/hide
* Cleanup entry change notification with entryview focus in/out
* Change Open URL shortcut to CTRL+SHIFT+U to conform with an "action"
including SHIFT
* Change Copy URL shortcut to CTRL+U to conform with "copy" without SHIFT
* Entry specific toolbar and menu items are disabled unless the entry
row has focus (prevents unintended actions)
* Reword security setting for password visibility in entry edit view
* Add shortcut to hide/unhide usernames (CTRL+SHIFT+B)
* Organize entry menu
* Fix#1588 - show keyboard shortcuts in context menu
* Fix#2403 - Change auto-type shortcut to CTRL + SHIFT + V
* Fix#2096 - Add (CTRL+F) to search bar background
* Fix#2031 & Fix#2266 - add shortcut to hide/unhide passwords (CTRL+SHIFT+C)
* Fix#2166 - Add reveal password button to entry preview
* Add CLI commands show --totp and totp-clip for handling TOTPs, resolves#2429.
* Adding tests for new CLI TOTP commands
* Update keepassxc-cli man page.
QTextStream uses the system default locale, but this breaks in
various situations: (1) It does not work on the native Windows shell
(cmd.exe, Powershell), since the default Windows locale is Windows-1252,
but the shell uses Windows-850. (2) It also breaks on *nix systems where
the locale is Latin1 or C, which is the case for most CI systems or
build servers.
We allow overriding the detected codec by setting the ENCODING_OVERRIDE
environment variable, but otherwise prefer Windows-850 on Windows and
UTF-8 on any other system, even if LANG is set to something else.
This resolves#2413
The CLI module was lacking unit test coverage and showed some severe
coding style violations, which this patch addresses.
In addition, all uses of qCritical() with untranslatble raw char*
sequences were removed in favor of proper locale strings. These are
written to STDERR through QTextStreams and support output
redirection for testing purposes. With this change, error messages don't
depend on the global Qt logging settings and targets anymore and go
directly to the terminal or into a file if needed.
This patch also fixes a bug discovered during unit test development,
where the extract command would just dump the raw XML contents without
decrypting embedded Salsa20-protected values first, making the XML
export mostly useless, since passwords are scrambled.
Lastly, all CLI commands received a dedicated -h/--help option.
* Create history-based merging that keeps older data in history instead of discarding or deleting it
* Extract merge logic into the Merger class
* Allows special merge behavior
* Improve handling of deletion and changes on groups
* Enable basic change tracking while merging
* Prevent unintended timestamp changes while merging
* Handle differences in timestamp precision
* Introduce comparison operators to allow for more sophisticated comparisons (ignore special properties, ...)
* Introduce Clock class to handle datetime across the app
Merge Strategies:
* Default (use inherited/fallback method)
* Duplicate (duplicate conflicting nodes, apply all deletions)
* KeepLocal (use local values, but apply all deletions)
* KeepRemote (use remote values, but apply all deletions)
* KeepNewer (merge history only)
* Synchronize (merge history, newest value stays on top, apply all deletions)
This patch implements a new database wizard to guide users through the process
of setting up a new database and choosing sane encryption settings.
It also reimplements the master key settings to be more
user-friendly. Users can now add, change, or remove individual composite
key components instead of having to set all components at once. This
avoids confusion about a password being reset if the user only wants to
add a key file.
With these changes comes a major refactor of how database composite keys and key
components are handled. Copying of keys is prohibited and each key
exists only once in memory and is referenced via shared pointers. GUI
components for changing individual keys are encapsulated into separate
classes to be more reusable. The password edit and generator widgets
have also been refactored to be more reusable.
* Eliminate TOTP logic from GUI elements
* Consolidate TOTP functionality under the Totp namespace
* Eliminate guessing about state and encoders
* Increased test cases
* Add entry view column for TOTP [#2132]
* General code cleanup, reduction of unnecessary steps, separation of concerns
* Rename SetupTotpDialog to TotpSetupDialog for consistency
The previous default was to expect passphrases to be ASCII or
rather Latin-1. It would be reasonable to expect modern keys to
use UTF-8 instead.
This is a non-breaking change if passphrases only use characters
that fall within ASCII.
Fixes#2102
AES-256 uses a 32-byte (256-bit) key size. This un-breaks the loader and
tests added for AES-256-CBC and AES-256-CTR PEM keys.
* OpenSSHKey: correctly parse encrypted PEM AES-256-CBC/AES-256-CTR keys
* OpenSSHKey: use correct key derivation for AES-256
* Tests: Speed up AutoType testing
Decrease default autotype delay to 1 to improve test suite speed by
seconds. This shaves multiple seconds off the whole test suite. In some
cases, the largest part.
Also, initialize config just creating the test instance, just in case
that it ever depends on the configuration values at that point already.
* Tests: Speed up Kdbx4 testing
This speeds up the Kdbx4 tests by using parameters optimized for speed
for the key derivation functions. On an i7-6700K the tests run close to
50% faster with this change (about 1.5s vs. 3s).
