[PATCH 5/5] Add a self-update mechanism for setup.exe

[PATCH 5/5] Add a self-update mechanism for setup.exe

[Jon TURNEY]

Updating setup.exe has 3 stages:
1) Download updated setup.exe to a temporary location
2) Execute that temporary copy of setup.exe with --copy-to instructing
it to copy itself over the setup.exe to be updated
3) Execute the updated setup.exe with --remove-from instructing it
to delete the temporary copy

A named mutex is used to ensure setup exits from each stage before
the next stage can start.

Unfortunately, at the moment, we don't usefully check the setup version number
until after we have downloaded and parsed setup.ini, which is perhaps a bit
late to offer to update setup.exe

v2: Address comments from Dave Korn
Properly quote arguments to ensure spaces in paths are handled safely
Place the setup URL in a string resouce

2011-03-29  Jon TURNEY  <jon.turney@dronecode.org.uk>

	* res.rc (IDS_OLD_SETUP_VERSION): Change text to offer to download
	new version of setup.
	(IDS_SETUP_URL): Added string resource.
	* resource.h (IDS_SETUP_URL): Added resource identifier.
	* main.cc (wait_for_exit, self_update_remove_from,
	self_update_copy_to, WinMain): Add -copy-to and --remove-from options
	for self-update process.
	* ini.cc (self_update_download): New function to download updated
	setup.
	(do_ini_thread): Prompt to download updated setup if a newer
	version exists.  Return a result indicating what should happen
	next.
	* threebar.h (PropertyPage::OnFinish): Add an implementation of
	OnFinish virtual function for this class.
	* threebar.cc (OnFinish): Ditto.
	 (OnMessageApp): Setup should finish on WM_APP_SETUP_INI_DOWNLOAD_COMPLETE
	if an updated setup was downloaded.

2011-03-29  Jon TURNEY  <jon.turney@dronecode.org.uk>

	* include/getopt++/DefaultFormatter.h (DefaultFormatter): Fix option string
	formatting when it has no short option.

[PATCH 2/5] Allow setup to parse more than 3 versions from the setup.ini file

[Jon TURNEY]

This recognizes any "[version]" line as introducing the information for
another version, which doesn't have one of the trust levels [curr], [prev]
or [test], and so isn't automatically selected when setup is

Since the value of <version> carries no meaning, it might make more sense
to mandate the use of a specific string like "[also]" or "[other]", or
perhaps "[prev-1]", "[prev-2]", etc.

I have written a corresponding patch to genini

Setup already does all the neccessary sorting in version order etc. to
use these additional versions.

2011-04-24  Jon TURNEY  <jon.turney@dronecode.org.uk>

	* PackageTrust.h (trusts): Add TRUST_OTHER.
	* inilex.ll: tokenize any other [version] as the T_OTHER token.
	* iniparse.yy: Add T_OTHER token and set package trust
	to TRUST_OTHER when it is used.

See Change #2.81 (which you apparently already know about).

I don't think setup.exe snapshots are very useful.  I never see much
indication that anyone uses them which is why I removed the code to
begin with.  I'd rather not raise setup.exe to the level of a "product"
which we have to beta test.

Sounds wonderful but couldn't you just rename the original setup.exe out
of the way, copy a new version over it in place, and then re-execute?

I'm just following a sequence of actions which a bit of google research found
other people had successfully used.

what you suggest seems like it should work, although I'd perhaps be a bit wary
of assuming that MoveFile() on the running executable works always.

I guess I misunderstood the check-in comment to mean "Remove these rules
because they have been broken by other changes" rather than "Remove these
rules because testing is unnecessary" :-)

Ok, there's one package maintainer who wants it.

Since this is, IMO, a rather large departure from past convention, it would
be nice to see if this is something that other people want.

This change will mean I'll need change to the program which generates
setup.ini so I'd like to make sure that this is going to be used.

[PATCH] Fix a cosmetic problem when there are no packages to install

[Jon TURNEY]

My previous patch introduces a cosmetic problem when there are no packages
to install.

Calling ThreeBarProgressPage::SetBar2(0, 0) indicates we are -2147483648%
done, while we iterate over all packages looking for packages to md5sum.

So avoid calling SetBar2() in that case.
