7a849482ea Switch the language standard to C++14 and use std::make_unique
Update mini_chromium to 7d6697ceb5cb5ca02fde3813496f48b9b1d76d0c

47ff9691450e Switch the language standard to C++14
7d6697ceb5cb Remove base/memory/ptr_util.h and base::WrapUnique

base::WrapUnique and std::make_unique are similar, but the latter is
standardized and preferred.

Most of the mechanical changes were made with this sed:

for f in $(git grep -l base::WrapUnique | uniq); do
  sed -E \
      -e 's%base::WrapUnique\(new ([^(]+)\((.*)\)\);%std::make_unique<\1>(\2);%g' \
      -e 's%base::WrapUnique\(new ([^(]+)\);%std::make_unique<\1>();%g' \
      -e 's%^#include "base/memory/ptr_util.h"$%#include <memory>%' \
      -i '' "${f}"
done

Several uses of base::WrapUnique that did not fit on a single line and
were not matched by this sed were adjusted manually. All #include
changes were audited manually, to at least move <memory> into the
correct section. Where <memory> was already #included by a file (or its
corresponding header), the extra #include was removed. Where <memory>
should have been #included by a header, it was added. Other similar
adjustments to other #includes were also made.

0758dbde9a win: Save contents of PEB to minidump to start making !peb work
This makes the basics of !peb work in windbg, however, pointed-to things
are not yet retrieved. For full functionality, a variety of pointers in
the PEB also needs to be walked and captured.

34aef02cc7 ubsan: Don’t call v[0] on empty vectors
Calling std::vector<>::operator[]() with an out-of-range index argument
is undefined behavior. In two cases, Crashpad used &v[0] in situations
where it was known that the address would not be used. These calls were
wrapped in conditions guarding against vector emptiness.

While s[0] is valid on an empty string, in two cases, Crashpad used
&s[0] as an argument to a system call that would be a no-op. These calls
were wrapped in similar conditions to avoid the system call.

The two uses of vector with undefined behavior were caught by the
following tests in crashpad_snapshot_test with
UndefinedBehaviorSanitizer:

[ RUN      ] CrashpadInfoClientOptions.OneModule
/Users/mark/compilatorium/llvm.build/bin/../include/c++/v1/vector:1493:12:
runtime error: reference binding to null pointer of type
'crashpad::process_types::section'
[       OK ] CrashpadInfoClientOptions.OneModule (72 ms)

[ RUN      ] ProcessSnapshotMinidump.Empty
/Users/mark/compilatorium/llvm.build/bin/../include/c++/v1/vector:1493:12:
runtime error: reference binding to null pointer of type
'MINIDUMP_DIRECTORY'
[       OK ] ProcessSnapshotMinidump.Empty (1 ms)

The Crashpad codebase was audited by searching for resize() calls and
analyzing how resized strings and vectors are used.

d5ddd14ee1 Improve map insertion operations.
Add MapInsertOrReplace<>() to insert a key-value pair into a map if the
key is not already present, or replace the existing value for key if the
key is present. The original value can optionally be returned to the
caller in this case.

Map insertions now use either MapInsertOrReplace<>() or
std::map<>::insert() directly.

Use MapInsertOrReplace<>() when the map should be updated to contain a
mapping from a key to a value regardless of whether the key is already
present.

Use std::map<>::insert() to insert a mapping from a key to a value
without replacing any existing mapping from a key, if present. If it is
important to know whether an existing mapping from a key was present,
use the returned std::pair<>.second. If it is important to know the
existing value, use the returned std::pair<>.first->second.

This change has a slight positive impact on performance.

6bf80c3e48 Add MinidumpCrashpadInfo::report_id.
Now that Chrome’s about:crashes displays the crash report UUID, I wanted
to add it to the minidump. In the future, we may be able to index these
on the server. This will also help identify dumps that correspond to the
same event once we’re equipped to convert between different formats.

Ideally, this new field is populated with the same UUID used locally in
the crash report database. To make this work,
CrashReportDatabase::NewReport must carry the UUID. This was actually
part of CrashReportDatabaseWin’s private extension to NewReport, so that
extension subclass can now be cleaned up.

359bdd8622 Carry the client ID from the database all the way through upload.
The client ID is added to a new field, MinidumpCrashpadInfo::client_id,
in each minidump file that is written. The ProcessSnapshot::ClientID()
gives access to value at the snapshot level. In the upload thread,
client IDs are retrieved from minidump files and used to populate the
“guid” HTTP form parameter.

The Breakpad client supplies these values at upload without hyphens and
with all capital letters. Currently, the Crashpad client uses hyphens
and lowercase letters when communicating with a Breakpad server.

445c0eae7c snapshot: Add a minimal ModuleSnapshotMinidump and accessor from
ProcessSnapshotMinidump.

ModuleSnapshotMinidump is currently only capable of reading module
annotations, in both vector and simple-dictionary forms. It does not
read any other module information from minidump files. These annotations
are all that are necessary to be able to upload Crashpad-produced
minidumps to Breakpad crash processor servers, because Breakpad accepts
them as HTTP POST parameters, while Crashpad places them in the minidump
file itself.

40b931bd8e Add ProcessSnapshotMinidump, the beginning of the minidump variant of
the Snapshot family.

For the time being, only ProcessSnapshotMinidump::AnnotationsSimpleMap()
is implemented. In order to complete the initial uploader for Crashpad,
ModuleSnapshotMinidump::AnnotationsSimpleMap() is also needed, to be
accessed by ProcessSnapshotMinidump::Modules().
