The _tmp buffer used in STRNCATF is too small for several callers,
which might lead to truncated output in some situations.
For example, GCC 11 warns:
src/third_party/libdisasm/x86_format.c:899:40: warning: ‘%s’ directive output may be truncated writing up to 63 bytes into a region of size 32 [-Wformat-truncation=]
899 | STRNCATF( buf, "%s:", str, len );
| ^~~~~ ~~~
src/third_party/libdisasm/x86_format.c:34:38: note: in definition of macro ‘STRNCATF’
34 | snprintf( _tmp, sizeof _tmp, fmt, data ); \
| ^~~
src/third_party/libdisasm/x86_format.c:899:41: note: format string is defined here
899 | STRNCATF( buf, "%s:", str, len );
| ^~
In file included from /usr/include/stdio.h:894,
from src/third_party/libdisasm/x86_format.c:1:

Getting started (from main)
-
First, download depot_tools and ensure that they’re in your
PATH. -
Create a new directory for checking out the source code (it must be named breakpad).
mkdir breakpad && cd breakpad -
Run the
fetchtool from depot_tools to download all the source repos.fetch breakpad cd src -
Build the source.
./configure && makeYou can also cd to another directory and run configure from there to build outside the source tree.
This will build the processor tools (
src/processor/minidump_stackwalk,src/processor/minidump_dump, etc), and when building on Linux it will also build the client libraries and some tools (src/tools/linux/dump_syms/dump_syms,src/tools/linux/md2core/minidump-2-core, etc). -
Optionally, run tests.
make check -
Optionally, install the built libraries
make install
If you need to reconfigure your build be sure to run make distclean first.
To update an existing checkout to a newer revision, you can
git pull as usual, but then you should run gclient sync to ensure that the
dependent repos are up-to-date.
To request change review
-
Follow the steps above to get the source and build it.
-
Make changes. Build and test your changes. For core code like processor use methods above. For linux/mac/windows, there are test targets in each project file.
-
Commit your changes to your local repo and upload them to the server. http://dev.chromium.org/developers/contributing-code e.g.
git commit ... && git cl upload ...You will be prompted for credential and a description. -
At https://chromium-review.googlesource.com/ you'll find your issue listed; click on it, then “Add reviewer”, and enter in the code reviewer. Depending on your settings, you may not see an email, but the reviewer has been notified with google-breakpad-dev@googlegroups.com always CC’d.
