Description:
|
|
This contains Chromium's locally patched copy of tcmalloc.
|
|
|
|
Contents:
|
|
|
|
chromium/
|
|
|
|
The chromium patched sources, copied from the vendor/
|
|
subdirectory and containing our local modifications.
|
|
|
|
We only copy over the vendor/src/ subdirectory (the only piece
|
|
we need) but still leave it in a chromium/src/ subdirectory to
|
|
keep the directory structures in parallel.
|
|
|

Vanilla sources from upstream:

HOWTOs:
|
|
|
|
Take a new version from upstream:
|
|
|
|
1) Grab the revision:
|
|
|
|
$ svn export [-r {tcmalloc-rev}] \
|
|
http://gperftools.googlecode.com/svn/trunk \
|
|
vendor-{tcmalloc-rev}
|
|
|
|
2) Check for added or deleted files:
|
|
|
|
$ diff -q -r -x .svn vendor vendor-{tcmalloc-rev}
|
|
|
|
3) Copy the new revision on top of the checked-in vendor branch:
|
|
|
|
$ cp -r vendor-{tcmalloc-rev}/* vendor
|
|
|
|
C:\> xcopy /e/y/i vendor-{tcmalloc-rev}\* vendor
|
|
|
|
4) Make all vendor files non-executable.
|
|
|
|
$ find . -executable -type f -exec chmod a-x {} \;
|
|
|
|
5) "svn add" or "svn rm" added or removed files (based on your
|
|
"diff -q -r" output from above)
|
|
|
|
6) Create the CL, upload, check it in:
|
|
|
|
$ gcl change CL
|
|
$ gcl upload CL
|
|
$ gcl commit CL
|
|
|
|
Note the revision number since you're going to want to merge
|
|
that to the local chromium branch.
|
|
|
|
Merge a new upstream version with our local patched copy:
|
|
|
|
1) Merge the local revision to chromium/src
|
|
|
|
$ svn merge -c {chrome-rev} svn://chrome-svn/chrome/trunk/src/third_party/tcmalloc/vendor/src chromium/src
|
|
|
|
2) Resolve any conflicts
|
|
|
|
3) Create the CL, upload, check in:
|
|
|
|
$ gcl change CL
|
|
$ gcl upload CL
|
|
$ gcl commit CL
|
|
|
