* refactor applypatch and friendsDoug Zongker2010-02-221-65/+107
| | | | | | | | | | | | | | | | | | | 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.) Change-Id: I217563c500012750f27110db821928a06211323f
* relocate applypatch; add type system and new functions to edifyDoug Zongker2010-02-182-52/+190
| | | | | | | | | | | | | | | | | | | | | | | | | - 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. b/2361316 - VZW Issue PP628: Continuous reset to Droid logo: framework-res.apk update failed (CR LIBtt59130) Change-Id: Ibd038074749a4d515de1f115c498c6c589ee91e5
* bump updater API version to 3; deprecate firmware update commandDoug Zongker2010-02-033-42/+7
| | | | | | | | | 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. Change-Id: I80858951ff10ed8dfff98aefb796bef009e05efb
* add a one-argument version of package_extract_fileDoug Zongker2010-02-011-24/+69
| | | | | | | | | | | 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.

* delete files before symlinking; log error messagesDoug Zongker2009-09-181-3/+21
| | | | | | 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).
* add a run_program() function to edifyDoug Zongker2009-09-101-0/+49
| | | | | Handy for producing debugging OTA packages (eg, running sqlite3 or whatever in recovery).

| | * remove updater from the user system imageDoug Zongker2009-06-261-1/+6
| | | | | | | | | | | | | | | | | | | | | 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.

| * improve updater progress barDoug Zongker2009-06-241-3/+21
| | | | | | | | | | | | 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.
* | add device extension mechanism to updaterDoug Zongker2009-06-222-1/+43
|/ | | | | | | 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 file_getprop() to updaterDoug Zongker2009-06-181-11/+100
| | | | | | | 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.
* let the "firmware" command take the file straight from the packageDoug Zongker2009-06-171-3/+4
| | | | | | | | 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.
* fixes to edify and updater scriptDoug Zongker2009-06-122-67/+124
| | | | | | | | | | | | | | | | | | | | | 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".
* edify extensions for OTA package installation, part 2Doug Zongker2009-06-123-7/+278
| | | | | | | | | | | | | | | | | | 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.
* edify extensions for OTA package installation, part 1Doug Zongker2009-06-115-0/+555
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).
