It currently does a couple of things. 1) Add an alias 'svn-rev' to git so that you can look up a legacy commit by its svn revision number. This enables you to type git svn-rev 1234 and git will show the commit log entry relating to SVN r1234. 2) Sets up tracking information for the user's private name area in the git repo. It tries to figure out some sensible answers to the data it needs, but allows the user to override the values. It then creates the fetch and push entries that are needed for tracking the extra refs. This implements one part of the recommendations that I've proposed in svnwrite.html for dealing with private branches. It should be possible to run the script more than once and for it to DTRT. If you change your answers the configuration should be correctly updated. 2020-01-10 Richard Earnshaw <rearnsha@arm.com> * gcc-git-customization: New file.

The following patch adds the descr/undescr aliases (for converting to monotonically increasing revision numbers and back) there next to svn-rev. Both have been changed to use basepoints/gcc-* tags instead of branchpoints/gcc-*, the first one now supports --full option, where $ git descr origin/master r10-5835 $ git descr --full origin/master r10-5835-g1fc15853e301337b46d7f1234966a6244ef0cdab where the second form is what is used in gcc-cvs mail bodies and bugzilla comments from commits, the former what is used in the subjects. The second alias has been tweaked to use git config --get gcc-config.upstream with fallback to origin to be able to deal with non-default upstream configurations.

Sourceware was on the CBL <https://www.abuseat.org/> at that time until I noticed (via email delays, since my mail server uses some DNSBLs as a basis for greylisting) and removed it. I don't know why it got listed but have no reason to think it related to the high load on the system. Probably your mail server uses the CBL, or another DNSBL containing it, as a basis for rejecting email. -- Joseph S.

A couple more tweaks to this file and I've now checked it in. 1) Added the ability to select the prefix for the personal namespace. This will be cached. If you change it, then the push operations will be updated (but any local branches you will have to rename if you want them to continue working afterwards). 2) Removed the + from the added push spec.
