| 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 |
