Build the GTK dialog as a separate shared library which
is embedded into the main updater binary.
At runtime the updater extracts the shared library and attempts to load it.
If this succeeds, the GTK UI is used, otherwise the updater will fall
back to something else - currently a silent install.
The current update dialogs do not support retry/cancel - if a file
cannot be installed the update will just fail with an error and
any partial install will be reverted.
Following the change to FileOps::removeFile() to support 'removal'
of files that are in use in Windows, the cleanup of the updater's
temporary directory can be performed from the non-elevated updater
setup process once the main install process has returned.
This removes the --mode cleanup run mode in the updater.
* On Windows FileOps::removeFile() fails for updater.exe
since that file is in use by the current process.
Whilst it is not possible to remove the file whilst it
is in use, it can be moved or scheduled for deletion on reboot.
This commit changes FilesOps::removeFile() to simulate the
behavior of unlink() on Linux by moving in-use files to
a temporary directory and then scheduling for them to
be removed on restart.
There is no locking on the Log file so conflicting updater processes
may corrupt each others' entries - although in practice this has not
been a problem yet.
Previously the application was restarted from the main install process, which may have
been elevated. The main application must be started from a non-elevated updater/updater.exe
process otherwise the main app will inherit the elevated status from its parent.
* Modify ProcessUtils::runElevated() to return the status code of the process
* Change UpdateInstaller to run the main installation synchronously from the initial
updater process in the case where elevation is not required.
* Remove calls in main.cpp to relaunch the main application after the UI is closed.
Instead of moving the whole <update> section to an embedded <update-v3>
node, just use a different name for the <install> section since older
clients will ignore the new <packages> section.
For older clients:
* The <install> section lists the packages to download. This will exist
in addition to the <packages> section.
* The real <install> section listing the files to install is renamed to
<install-v3>
* Add WIN32 flag to add_executable() so that cmake generates a GUI application
* Add WinMain() entry point which converts the unicode command line arguments to ANSI and then calls the standard main() entry point.
The unit test continues to pass although I am not sure whether
converting command-line args from Unicode to ANSI will cause problems
with filenames passed on the command-line that contain non-ANSI
characters.
std::string::npos is defined as the unsigned type size_t but given a value of -1,
resulting in a warning when trying to compare an unsigned int with a size_t.
Fix this by declaring pos as a size_t.
* Fix ProcessUtils::runAsyncUnix() not returning a value
* Fix UpdateDialogGtk::updateRetryCancel() not returning a value
* Add missing includes in TestUpdaterOptions.cpp
* Fix unsigned/signed int comparisons
This prevents the dialog being closed part-way through update installation,
leaving the user unable to restart the application afterwards by clicking
the 'Finish' button.
UpdaterOptions::parse() will probably not have a need to modify its
arguments but for consistency with the declaration of main() it takes a char*,
so strdup() the strings.
In the event of a failed update, display the details in a message
box and allow the user to restart the old application once the
update has been reverted.
Details of the problem will also be written to the log file.
This prevents the user closing the dialog whilst the update is in
progress. Once the update has been installed, the user can click
the 'Finish' button to close the dialog and restart the application.
* Link the updater application with the Cocoa framework on Mac
* Construct a UI in code and display it when running the main install process.
Usually UIs on Mac are contained in a .nib file created with Interface Builder
but in this case the UI is created directly in code to meet the single-binary requirement,
although it may be possible to bundle the .nib into the binary itself.
