git_futils_mkdir_*: make a relative-to-base mkdir

2015-09-17T14:00:35+00:00

Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter
assumes that we own everything beneath the base, as if it were
being called with a base of the repository or working directory,
and is tailored towards checkout and ensuring that there is no
bogosity beneath the base that must be cleaned up.

This is (at best) slow and (at worst) unsafe in the larger context
of a filesystem where we do not own things and cannot do things like
unlink symlinks that are in our way.

iterator: use an options struct instead of args

refdb: delete a ref's reflog upon deletion

2015-07-12T17:08:06+00:00

Removing a reflog upon ref deletion is something which only some
backends might wish to do. Backends which are database-backed may wish
to archive a reflog, log-based ones may not need to do anything.

refdb: use the same id for old and new when renaming a reference

2015-03-08T15:50:27+00:00

When we rename a reference, we want the old and new ids to be the same
one (as we did not change it). The normal code path looks up the old id
from the current value of the brtanch, but by the time we look it up, it
does not exist anymore and thus we write a zero id.

Pass the old id explicitly instead.

Remove extra semicolon outside of a function

2015-02-15T20:07:05+00:00

Without this change, compiling with gcc and pedantic generates warning:
ISO C does not allow extra ‘;’ outside of a function.

Fix branch creation when branch name matches namespace of previously deleted branch

reference_create: validate loose names

2014-12-16T16:08:56+00:00

Validate loose reference names on Win32.

checkout: disallow bad paths on win32

2014-12-16T16:08:53+00:00

Disallow:
 1. paths with trailing dot
 2. paths with trailing space
 3. paths with trailing colon
 4. paths that are 8.3 short names of .git folders ("GIT~1")
 5. paths that are reserved path names (COM1, LPT1, etc).
 6. paths with reserved DOS characters (colons, asterisks, etc)

These paths would (without \\?\ syntax) be elided to other paths - for
example, ".git." would be written as ".git".  As a result, writing these
paths literally (using \\?\ syntax) makes them hard to operate with from
the shell, Windows Explorer or other tools.  Disallow these.

Introduce reference transactions

2014-09-30T13:44:32+00:00

A transaction allows you to lock multiple references and set up changes
for them before applying the changes all at once (or as close as the
backend supports).

This can be used for replication purposes, or for making sure some
operations run when the reference is locked and thus cannot be changed.

refs: copy the packed refs on iteration

2014-06-02T15:50:30+00:00

This lets us work without worrying about what's happening but work on a
snapshot.
