Mark Salyzyn 0c071c9de7 base: adb.exe build error
Windows build of adb is broken because of the lack of
std::chrono_literals and for an implementation of
android::boot_clock::now().

There will be another cleanup pass later that will move some instances back to
target.linux if the properties should be shared with target.android and
target.linux_bionic, but target.linux needs to be removed first.

Adam Lesinski a0360ad6a3 Merge "libziparchive: Use ReadAtOffset exclusively" 2017-07-25 22:22:21 +00:00
Adam Lesinski 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.

George Burgess IV 6466ced8f6 logging: make LOG(FATAL) always run with the static analyzer.
::android::base::GetMinimumLogSeverity() is defined externally, so the
static analyzer was allowed to assume that we continue executing after a
LOG(FATAL).

I manually audited all of the code I have access to, and the only
"change the minimum log severity" statements I can see keep FATAL
enabled (...and continuing after a FATAL is highly sketchy to me
anyway).

(I'm sure I tested this at some point in making the previous patch. I
probably broke it in a refactor before sending it out for review; my
bad. :) )

Bug: None
Test: m without the static-analyzer builds; m with it yields fewer
false positives.

George Burgess IV 7e771de38f logging: always enable DCHECK for the static analyzer
This helps us have less false-positives.

We do this instead of `#undef NDEBUG`, since undefing NDEBUG actually
gave us more false-positives (...and build breakages) than simply
leaving it defined.

Bug: None
Test: Ran the static analyzer across internal master. 213 fewer warnings
(15 Medium, 2 Low, the remainder are 'Analyzer'). All of the dropped
warnings I audited were false-positives. It adds ~3 Tidy warnings.

George Burgess IV 582ec2b078 fix static-analyzer logging/CHECK macros
Two small changes in one:

- `foo || for (;;abort()) bar();` isn't valid C or C++, since for is a
  statement. We need an expression instead.
- we'll now treat everything after LOG(foo) as unreachable in the
  static analyzer, as long as we can prove at compile-time that
  foo == FATAL.

The impact of this, running across internal master, is that we see ~50
fewer medium/high-severity false positives from clang-tidy. We see 15
new complaints about unreachable code (at the "tidy" severity), but all
of them are harmless AFAICT (e.g.

switch (foo) {
  // ...
  default:
    LOG(FATAL) << "Unhandled case!"; // or CHECK(false);
    break; // clang-tidy: unreachable break.
})

(Some of the macros were forcibly formatted by the clang-format hook)

Steven Moreland d10a023208 libbase: make vendor_available
By setting vendor_available, the following may become true:

* a prebuilt library from this release may be used at runtime by
  in a later releasse (by vendor code compiled against this release).
  so this library shouldn't depend on runtime state that may change
  in the future.
* this library may be loaded twice into a single process (potentially
  an old version and a newer version). The symbols will be isolated
  using linker namespaces, but this may break assumptions about 1
  library in 1 process (your singletons will run twice).

Background:

This means that these modules may be built and installed twice --
once for the system partition and once for the vendor partition. The
system version will build just like today, and will be used by the
framework components on /system. The vendor version will build
against a reduced set of exports and libraries -- similar to, but
separate from, the NDK. This means that all your dependencies must
also mark vendor_available.

At runtime, /system binaries will load libraries from /system/lib*,
while /vendor binaries will load libraries from /vendor/lib*. There
are some exceptions in both directions -- bionic(libc,etc) and liblog
are always loaded from /system. And SP-HALs (OpenGL, etc) may load
/vendor code into /system processes, but the dependencies of those
libraries will load from /vendor until it reaches a library that's
always on /system. In the SP-HAL case, if both framework and vendor
libraries depend on a library of the same name, both versions will be
loaded, but they will be isolated from each other.

It's possible to compile differently -- reducing your source files,
exporting different include directories, etc. For details see:

https://android-review.googlesource.com/368372

None of this is enabled unless the device opts into the system/vendor
split with BOARD_VNDK_VERSION := current.
