std::unique_ptr<z_stream, decltype(&deflateEnd)> strm(new z_stream(), deflateEnd);
Only the internally allocated buffers inside 'strm' would be free'd by
deflateEnd(), but not 'strm' itself.
This CL fixes the issue by moving 'strm' to stack variable. Note that we
only need to call deflateEnd() on successful return of deflateInit2().

bsdiff interface is changing such that it hides the suffix array
pointer from the public interface. This allows to use a different
suffix array data size depending on the input size, running much faster
in the normal case.

This way it stops requiring relative path ".." in LOCAL_C_INCLUDES

And move '#include "edify/expr.h"' into .cpp files. This breaks the
transitive dependency on libedify. Modules that include
"applypatch/applypatch.h" don't need to add libedify into their
dependency list, unless they really need anything from libedify.
Build libedify static library for host, which is needed by
libimgpatch.

Add a mandatory option in imgdiff to write the split info (i.e.
patch_size, tgt_size, src_ranges) to file when handling large apks.
Therefore, the caller of imgdiff can create split transfers based on
the info.

Test: unit tests pass

Due to the cache size limit for OTA generation, we used to split large
zip files linearly into pieces and do bsdiff on them. As a result, i) we
lose the advantage of imgdiff; ii) if there's an accidental order change
of some huge files inside the zip, we'll create an insanely large patch.
This patch splits the src&tgt more smartly based on the zip entry_name.
If the entry_name is empty or no matching source is found for a target
chunk, we'll skip adding its source and later do a bsdiff against the
whole split source image (this rarely happens in our use cases except
for the metadata inside a ziparchive).
After the split, the target pieces are continuous and block aligned,
while the sources pieces are mutually exclusive. (Some of the source
blocks may not be used if there's no matching entry_name in the target.)
Then we will generate patches accordingly between each split image
pairs.
Afterwards, if we apply imgpatch to each pair of split source/target
images and add up the patched result, we can get back the original
target image.
For example:
Input: [src_image, tgt_image]
Split: [src-0,tgt-0; src-1,tgt-1, src-2,tgt-2]
Diff: [ patch-0; patch-1; patch-2]
Patch: [(src-0,patch-0)=tgt-0; (src-1,patch-1)=tgt-1;
(src-2,patch-2)=tgt-2;]
Append: [tgt-0 + tgt-1 + tgt-2 = tgt_image]
Peformance:
For the small package in b/34220646, we decrease the patch size of
chrome.apk dramatically from 30M to 400K due to the order change of
two big .so files.
On two versions of angler, I also observe decent patch size decrease.
For chrome.apk, we reduced the size from 5.9M to 3.2M; and for
vevlet.apk from 8.0M to 6.5M.

In a rare case, a random chunk will pass both the gzip header check
and the inflation process; but fail the uncompressed length check in the
footer. This leads to a imgdiff failure. So, we should treat this chunk
as 'normal' instead of 'inflated' while generating the patch.

The SpaceMode (applypatch -s) was used in amend script (cupcake) only,
which has been removed since commit
9ce2ebf5d300eba5f6086583b0941ef68a3e4b42 (platform/build). The later
(and current) edify script uses apply_patch_space().
Note that other modes (PatchMode, CheckMode) of applypatch executable
are mostly used by install-recovery.sh script.

Mostly for applypatch family APIs like ApplyBSDiffPatch() and
ApplyImagePatch(). Changing to size_t doesn't indicate they would
necessarily work with very large size_t (e.g. > ssize_t), just
similar to write(2). But otherwise accepting negative length doesn't
make much sense.
Also change the return type of SinkFn from ssize_t to size_t. Callers
tell a successful sink by comparing the number of written bytes against
the desired value. Negative return values like -1 are not needed. This
also makes it consistent with bsdiff::bspatch interface.

We were using the below sequence prior to the CL in [1].
unique_fd fd(ota_open(...));
ota_close(fd);
fd.reset(ota_open(...));
fd.reset() may unintentionally close the newly opened FD if it
has the same value as the early ota_open. The CL in [1] changed to
"ota_close(fd.release())" to avoid the issue. This CL adds a new
overloaded function ota_close(unique_fd&) to handle the release
automatically.
Similarly add ota_fclose(std::unique_ptr<FILE>&).

We might end up in an infinite loop if read(2) reached EOF unexpectedly.
The problematic code in uncrypt mentioned in the bug has been fixed
by switching to libbase ReadFully(). So I grepped through the recovery

These were attempts to write partitions "conservatively" in hopes of
fixing the problems with writing the radio partition on Nexus 4. They
didn't work (a kernel patch was needed), but got left in. They make
writing of partitions unnecessarily slow (ie, we really shouldn't need
to sync() after every 4kb). Roll back most of them, but leave the
verification read-back in.

Nexus 4 has flash errors that manifest during large writes (eg, of the
radio partition). Writes of some blocks seem to be dropped silently,
without any errors being returned to the user level.
Make two changes to the partition-writing code:
- break it up into 1MB writes instead of writing partitions with a
single fwrite() call. Pause for 50ms in between every chunk.
- read the partition back after writing and verify that we read what
we wrote. Drop caches before reading so we (hopefully) are reading
off the actual flash and not some cache.
Neither of these should be necessary.

we wrote. Drop caches before reading so we (hopefully) are reading
off the actual flash and not some cache.
Neither of these should be necessary.

Make minzip log only a count of files when extracting, not individual
filenames. Make patching only chatter about free space if there's not
enough and compact the other messages.
Only the last 8k of the recovery log gets uploaded; this makes it more
likely that we will get all of it.

The bonus data option lets you give an additional blob of uncompressed
data to be used when constructing a patch for chunk #1 of an image.
The same blob must be available at patch time, and can be passed to
the command-line applypatch tool (this feature is not accessible from
edify scripts).
This will be used to reduce the size of recovery-from-boot patches by
storing parts of the recovery ramdisk (the UI images) on the system
partition.

When creating a new file using open(..., O_CREAT), it is an error
to fail to specify a creation mode. If a mode is not specified, a
random stack provided value is used as the "mode".
This will become a compile error in a future Android change.

The applypatch function is somewhat sloppy about freeing memory (since
it was originally a standalone binary). Fix some of that.

Let applypatch read and write EMMC partitions as well as MTD ones.
This enables incremental updates that include boot image changes, as
well as OTA of new recovery partitions.

When restarting a patch from crashing in the middle of a large file,
we're not finding the correct patch to apply to the copy saved in

An accidental variable declaration ("int enough_space = ..." instead
of "enough_space = " inside a block) shadowing the real one meant we
were always using the copy-to-cache path for patching, even when not
necessary. Remove it. Enforce an absolute minimum of free space as
well, to avoid running into problems patching small files, now that
the copy-to-cache path is (inadvertently) well-tested.

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.
