Make the mount and format functions take extra parameters describing
the filesystem type and add support for mounting and formatting ext4
filesystems on EMMC.
Change recovery to consistently use stdout for status messages instead
of mixing stdout and stderr.
|
|
Close the update package before invoking the binary, to allow the
installer to unmount /cache if it wants to. Add a function to allow
remounting of a mount as read-only.

Change the applypatch function to take meaningful arguments instead of
argc and argv. Move all the parsing of arguments into main.c (for the
standalone binary) and into install.c (for the updater function).
applypatch() takes patches as Value objects, so we can pass in blobs
extracted from the package without ever writing them to temp files.
The patching code is changed to read the patch from memory instead of
a file.
A bunch of compiler warnings (mostly about signed vs unsigned types)
are fixed.
Support for the IMGDIFF1 format is dropped. (We've been generating
IMGDIFF2 packages for some time now.)

- Move applypatch to this package (from build).
- Add a rudimentary type system to edify: instead of just returning a
char*, functions now return a Value*, which is a struct that can
carry different types of value (currently just STRING and BLOB).
Convert all functions to this new scheme.
- Change the one-argument form of package_extract_file to return a
Value of the new BLOB type.
- Add read_file() to load a local file and return a blob, and
sha1_check() to test a blob (or string) against a set of possible
sha1s. read_file() uses the file-loading code from applypatch so it
can read MTD partitions as well.
This is the start of better integration between applypatch and the
rest of edify.

Remove support for the HTC-specific "firmware" update command and the
corresponding edify function write_firmware_update(). This
functionality is now done by an edify extension library that lives in
vendor/htc.

Add a version of package_extract_file that returns the file data as
its return value (to be consumed by some other edify function that
expects to receive a bunch of binary data as an argument). Lets us
avoid having two copies of a big file in memory (extracting it into
/tmp, which is a ramdisk, and then having something load it into
memory) when doing things like radio updates.

The symlink() function should remove existing files before creating
symlinks, so scripts are idempotent. Log messages when various system
calls fail (but don't make the whole script fail).

Handy for producing debugging OTA packages (eg, running sqlite3 or
whatever in recovery).
|
|
updater (which is only needed in OTA packages) is getting included in
/system/bin, where it just takes up (quite a bit of) space. Use the
hack of including it only in eng builds so it's not there for user
builds.
|
|
We were inadvertently skipping over the first filename in the list of
arguments.
|
|
Let recovery accept set_progress commands to control progress over the
'current segment' of the bar. Add a set_progress() builtin to the
updater binary.
|
|
Allow devices (in BoardConfig.mk) to define additional static
libraries to be linked in to updater, to make device-specific
functions available in edify scripts. Modify the updater makefile to
arrange for device libraries to register their edify functions.
|
|
Add a function to read a property from a ".prop"-formatted file
(key=value pairs, one per line, ignore # comment lines and blank
lines). Move ErrorAbort to the core of edify; it's not specific to
updater now that errors aren't stored in the app cookie.
|
|
To do a firmware-install-on-reboot, the update binary tells recovery
what file to install before rebooting. Let this file be specified as
"PACKAGE:<foo>" to indicate taking the file out of the OTA package,
avoiding an extra copy to /tmp. Bump the API version number to
reflect this change.

A few more changes to edify:
- fix write_raw_image(); my last change neglected to close the write
context, so the written image was corrupt.
- each expression tracks the span of the source code from which it
was compiled, so that assert()'s error message can include the
source of the expression that failed.
- the 'cookie' argument to each Function is replaced with a State
object, which contains the cookie, the source script (for use with
the above spans), and the current error message (replacing the
global variables that were used for this purpose).
- in the recovery image, a new command "ui_print" can be sent back
through the command pipe to cause text to appear on the screen.
Add a new ui_print() function to print things from scripts.
Rename existing "print" function to "stdout".

Adds more edify functions for OTAs:
is_mounted getprop apply_patch apply_patch_check apply_patch_space
write_raw_image write_firmware_image package_extract_file
This allows us to install radios, hboots, boot images, and install
incremental OTA packages.
Fixes a couple of dumb bugs in edify itself:
- we were doubling the size of the function table each time it was
*not* full, rather than each time it was full
- "no such function" errors weren't visible to the parser, so they
didn't prevent execution of the script.

Adds the following edify functions:
mount unmount format show_progress delete delete_recursive
package_extract symlink set_perm set_perm_recursive
This set is enough to extract and install the system part of a (full)
OTA package.
Adds the updater binary that extracts an edify script from the OTA
package and then executes it. Minor changes to the edify core (adds a
sleep() builtin for debugging, adds "." to the set of characters that
can appear in an unquoted string).
