c36b80928b zip_archive: Fix a few more badly written tests.
Fix failures in DataDescriptor related tests due to to a bad call to
SetZipString (undefined behaviour). Also fix a typo in the test for
invalid descriptors, we were asserting things on the wrong array.

f37bb8e45b zip_archive: Fix tests broken by 1f93d71022.
Moving to std::hash changed iteration order but these tests should
not have relied on hash_map iteration order anyway.

834326ce7a Get rid of unneeded allocations in Extract...() APIs
Both Extract...() functions don't need dynamic allocation
for the writers, as those are strictly scoped. This CL
changes heap allocation to stack allocation.

1f93d71022 use std::hash instead of hashing byte by byte
This patch uses libcxx's string_view hashing.  The performance is better than the
current implementation, and almost the same as for the hashing implementation amended
by the patch in https://android-review.googlesource.com/404742

The following experiments were conducted on a HiKey aarch64 A53.

b88aa023d4 Merge "fastboot should fail if it runs out of space while unzipping." 2017-10-28 01:16:29 +00:00
Elliott Hughes
4089d34b93 fastboot should fail if it runs out of space while unzipping.
Previously fastboot would carry on regardless if decompression failed:

  fastboot: archive does not contain 'vbmeta.img'
  fastboot: extracting vendor.img (260 MB)...
  fastboot: W/ziparchive(56777): Zip: unable to allocate  272781472 bytes at offset 0 : No space left on device
  fastboot: failed to extract 'vendor.img': I/O error
  fastboot: archive does not contain 'vendor_other.img'
  fastboot: wiping userdata...

This is because all but "boot" and "system" are considered "optional",
and the implementation of "optional" was "ignore any failures". What it
_should_ have meant was "it's okay if these don't exist, but if they do,
failures matter".

Fix this logic, use die() more aggressively, and remove spurious "\n"s
from die() format strings.

Also fix spurious whitespace in the libziparchive format string. Before:

  Zip: unable to allocate  272781472 bytes at offset 0 : No space left on device

After:

  Zip: unable to allocate 272781472 bytes at offset 0: No space left on device

Remove dependencies on zip_archive specific data structures. In follow

de117e4a49 libziparchive: Use ReadAtOffset exclusively
The use of ReadAtOffset is meant to allow concurrent access
to the zip archive once it has been loaded. There were places
where this was the case, and some places that did a seek + read
combination, which could lead to data races.

NOTE: On Windows, we are not using pread as the implementation of
ReadAtOffset, therefore the guarantees on Windows are weaker.

On Linux, pread allows the file descriptor to be read at a specific
offset without changing the read pointer. This allows inherited fd's
and duped fds to be read concurrently.

On Windows, we use the ReadFile API, which allows for an atomic seek +
read operation, but modifies the read pointer. This means that any mix
use of ReadAtOffset and Read will have races. Just using ReadAtOffset is
safe.

For the Windows case, this is fine as the libziparchive code now only
uses ReadAtOffset.

162b705801 zip_archive: validate data descriptor contents.
- Ensure that the compressed and uncompressed lengths in the data
  descriptor match those in the central directory.

- Calculate CRCs for compressed entries and ensure that those CRCs
  match the information in the central directory / data descriptor.
  This is currently guarded by a flag and will be turned on at a
  later stage.

- Finally, always trust the LFH when it comes to indicating the
  existence of a data descriptor. We no longer require this info to
  match the central directory to bring this in line with other zip
  processing tools. (see NOTE in the included change).

f8e96ea2d1 Merge "add a performance benchmark for libziparchive" 2017-05-30 19:44:52 +00:00
Sebastian Pop
0a94c56463 add a performance benchmark for libziparchive
This patch adds two benchmarks that measure the performance of some
operations of libziparchive.

Both benchmarks are creating a temporary zip file containing file
names of uniformly distributed lengths.  The creation of the zip
file is not timed in the benchmarks.

- FindEntry_no_match tries to find an inexisting entry in the files
  of the zip archive, in order to force the code to examine all the
  files in the archive.

- Iterate_all_files uses the iterate function to list all the files
  in the archive.

libziparchive is a library which belongs to vndk-cap. Mark it
vendor_available to enable header-abi-dumper's invocation to identify it
as a part of the vndk.

d987c9dd9e ZipWriter: Keep LFH and CFH in sync
We change the GPB in the LocalFileHeader if the entry can not
have a trailing DataDescriptor. Make sure to patch the
CentralFileHeader to have the same bits set.

Modify ZipArchive to check that the data descriptor bit is consistent
between Central and Local file headers.

e2fa70bcb0 ZipWriter: Do not write DataDescriptor for STORED files
Older implementations of ZIP (Java's ZipInputStream) don't
like a Data Descriptor trailing after an uncompressed entry.

If the FILE is seekable, and the entry is uncompressed, seek
back to the header and write out the crc and sizes.

537713bace libziparchive: Add ability to backup in ZipWriter
Based on the compressed size of a file entry,
the decision needs to be made to instead store the file
uncompressed. This adds support to ZipWriter to backup
its last file entry.

The file is now always truncated when the EOCD is written out,
to account for the case where a file entry is backed-up and the
resulting file written is much smaller, leaving garbage data at
the end of the file.

This change also includes a rename of FileInfo -> FileEntry.
This struct was private (now public), so it shouldn't affect any
clients.

86e80b9be0 Use shared lib of libutils, libz and libbase.
libutils, libz and libbase are being used as shared lib by many other
modules.
So using their shared lib will reduce total image size.

Size diffs on angler build image are as follows.

libziparchive.so  : 103844 -> 41680 (-62164)
libnativeloader.so:  50824 -> 25104 (-25720)
total             : (-87884)

Test: building succeeded, and the image was tested on angler.
