Improve the speed of incremental OTA install by treating unchanging
gzip chunks as normal chunks, avoiding a decompress/recompress cycle.
This reduces the time needed to apply a patch to a boot image where
the kernel has not changed from ~30 seconds to ~2 seconds, on an opal.
SignApk fixes the timestamp of the signature files it adds. Use that
same timestamp for all the files, so that the modtime doesn't vary
from build to build. (Incremental OTAs currently spend significant
time rewriting every .apk to do nothing but patch in timestamp
changes.)
The build servers have GNU coreutils 5.93, where stat does not output
a newline. Ubuntu hardy has GNU coreutils 6.10, where it does.
Lacking a newline messes up the summing of the sizes. Fix
get-file-size to remove the newline if present, and make the total
calculation in assert-max-file-size more robust.
Also, if the image was too big, it was not actually making the build
fail (because /bin/false was not the last thing called). Fix that so
it does.
When I moved the building of the recovery image upwards in the file, I
moved an 'endif' surrounding it but not the matching 'if'. How did
this ever work?
There are currently two errors in the way we test the size of built
images against the size of the partition on the hardware:
- the limits in BoardConfig.mk are set with the data size only, but
images contain an extra 64 bytes per 2048-byte page. This means we
think the partition is about 1/32 smaller than it really is.
- when we deliver a build via OTA, the system partition ends up with
one more file than when it's flashed via fastboot. That file is a
copy of the recovery image. In order to be able to OTA a build, we
need to make sure the system partition has enough room for all the
system files plus the recovery image as well.
For the kila system partition, these errors are roughly the same order
of magnitude -- about 2MB, one in the "safe" direction, one in the
"unsafe" direction. This change fixes both to give us a more accurate
notion of how close we are to the limit.
Make the build emit a warning (but not fail) when the size is within
32kb of the limit.
Also, include the values of the partition size limits in an info file
in the target-files package, so post-processing tools can use them
without parsing the BoardConfig.mk file.
If the source target-files zip omits files needed to build the
recovery and/or boot images, leave them out instead of dying with an
error. This lets build like "generic-userdebug" work.
Generic targets don't have a list of defined bootloaders. Instead of
failing to build an OTA package, just omit the constraint.
Fix bad references to ExternalError.
* changes:
Put the java source file list files somewhere where they don't conflict with the .class files that are getting zipped up, and delete them when we're done with them.
Split the details of generating script syntax into a generator class:
one for amend (whose output should be equivalent to the current
output), and one for edify.
Fix 'otatools' build rule to build imgdiff.
The ota and img building scripts contained some hardcoded 'linux-x86'
paths. Remove and replace with a slightly redefined -p option.
Modify Makefile to pass correct -p when building.
The SDK build used to have the update package as a dependency, in
order to force various image files to be built. Now the the update
package can't be built for sdk-eng, list the individual images needed
instead.
In python 2.5 and earlier, ZipFile.writestr(filename, data) results in
the file being added to the archive with permissions 000. (See
http://svn.python.org/view?view=rev&revision=65235.) Work around this
by creating a ZipInfo object and setting the permissions explicitly.

AI 149839: make the home page's announcement block expandable...
primarily, this is to handle various lengths of text due to translations,
but also allows us to be more flexible WRT the content for the top section.
Automated import of CL 149839
Turn the bulk of applypatch into a static library so it can be used
from the updater. Also build it as a standalone executable for use by
the existing OTA mechanism.
