If a marker file indicates that an installer has been downloaded and verified
and is ready to install, but that installer file does not exist, log it and
revert to checking for update.
Also add logging to every code path that can remove the installer explicitly,
in case the missing installer is actually being killed off by some weird
sequence of state-machine transitions.
|
|
Also, delete it when done.

This eliminates the user expectation that s/he must click OK before the
updater will begin installing the new viewer.

changes to common libraries from the server codebase:
* Additional error checking in http handlers.
* Uniform log spam for http errors.
* Switch to using constants for http heads and status codes.
* Fixed bugs in incorrectly checking if parsing LLSD xml resulted in an error.
* Reduced spam regarding LLSD parsing errors in the default completedRaw http handler. It should not longer be necessary to short-circuit completedRaw to avoid spam.
* Ported over a few bug fixes from the server code.
* Switch mode http status codes to use S32 instead of U32.
* Ported LLSD::asStringRef from server code; avoids copying strings all over the place.
* Ported server change to LLSD::asBinary; this always returns a reference now instead of copying the entire binary blob.
* Ported server pretty notation format (and pretty binary format) to llsd serialization.
* The new LLCurl::Responder API no longer has two error handlers to choose from. Overriding the following methods have been deprecated:
** error - use httpFailure
** errorWithContent - use httpFailure
** result - use httpSuccess
** completed - use httpCompleted
** completedHeader - no longer necessary; call getResponseHeaders() from a completion method to obtain these headers.
* In order to 'catch' a completed http request, override one of these methods:
** httpSuccess - Called for any 2xx status code.
** httpFailure - Called for any non-2xx status code.
** httpComplete - Called for all status codes. Default implementation is to call either httpSuccess or httpFailure.
* It is recommended to keep these methods protected/private in order to avoid triggering of these methods without using a 'push' method (see below).
* Uniform error handling should followed whenever possible by calling a variant of this during httpFailure:
** llwarns << dumpResponse() << llendl;
* Be sure to include LOG_CLASS(your_class_name) in your class in order for the log entry to give more context.
* In order to 'push' a result into the responder, you should no longer call error, errorWithContent, result, or completed.
* Nor should you directly call httpSuccess/Failure/Completed (unless passing a message up to a parent class).
* Instead, you can set the internal content of a responder and trigger a corresponding method using the following methods:
** successResult - Sets results and calls httpSuccess
** failureResult - Sets results and calls httpFailure
** completedResult - Sets results and calls httpCompleted
* To obtain information about a the response from a reponder method, use the following getters:
** getStatus - HTTP status code
** getReason - Reason string
** getContent - Content (Parsed body LLSD)
** getResponseHeaders - Response Headers (LLSD map)
** getHTTPMethod - HTTP method of the request
** getURL - URL of the request
* It is still possible to override completeRaw if you want to manipulate data directly out of LLPumpIO.
* See indra/llmessage/llcurl.h for more information.

Most of the merge was clean, a couple conflicts.
Brought over a couple patches manually for llpolymesh.

Responding to Lex's code-review comments.

Capture actual error output from mkdir and mv; display it to user.
Introduce mysudo function used by sudo_mv function for graphical sudo command.
Since update_install actually only displays a single status message, just use
zenity --info instead of a zenity progress box: need not update its message.
Borrow semantics for clear_message and status functions from xmenity script.
Introduce errorbox function so we only have to make zenity/xmessage test once.
Move cleanup, onexit to top so we can use for clear_message.

Test for existence of target name using -e rather than -f. (-d would work too,
but in this case we must respond to any name collision, whether file or
directory.)
Instead of terminating on failure, make sudo_mv return rc of the [sudo] mv
command to its caller. If the attempt to move new install to actual viewer
directory fails, restore previous viewer before failing.
When redirecting the script's stderr to updater.log, first save existing
stderr to another file descriptor, and restore it when we launch viewer.
Otherwise updater.log ends up collecting the viewer's duplicate stderr log
output!
The construct 'exec ... | program' doesn't work. In fact it causes any other
redirections on that command to fail too. Remove it -- real fix pending.

Now that the viewer's own background updater logic is responsible for
downloading a new installer, the only functionality we still use in
linux-updater that couldn't be expressed more simply in bash is the UI. But
since most Linux distros capable of running SL at all have zenity, and all
will have xmessage, we can handle even the UI part. Add xmenity wrapper script
so update_install doesn't have to care which is present, and make the bash
script that used to launch linux-updater do the real work.
