shelve: disallow commit while unshelve is in progress Before this patch, commit is allowed even while unshelve is in progress. In the other hand, "hg unshelve --abort" and "hg unshelve --continue" check whether parent revisions of the working directory have changed or not since last "hg unshelve", and abort without clearing state for unshelve in progress if they have. This causes that accidental commit makes clearing state for unshelve difficult in ordinary ways. This patch disallows commit while unshelve is in progress for consistency.

bdiff: avoid a memory error on malloc failure

shelve: use rebase instead of merge (issue4068) Previously, shelve used merge to unshelve things. This meant that if you shelved changes on one branch, then unshelved on another, all the changes from the first branch would be present in the second branch, and not just the shelved changes. The fix is to use rebase to pick the shelve commit off the original branch and place it on top of the new branch. This means only the shelved changes are brought across. This has the side effect of fixing several other issues in shelve: - you can now unshelve into a file that already has pending changes - unshelve a mv/cp now has the correct dirstate value (A instead of M) - you can now unshelve to an ancestor of the shelve - unshelve now no longer deletes untracked .orig files Updates tests and adds a new one to cover the issue. The test changes fall into a few categories: - I removed some excess output - The --continue/--abort state is a little different, so the parents and dirstate needed updating - Removed some untracked files at certain points that cluttered the output

doc: use double quotation mark to quote arguments in examples for Windows users On Windows, only double quotation mark can quote command line arguments. So, this patch uses double quotation mark to quote command line arguments in all examples of online help document.

rebase: improve error message for more than one external parent

largefiles: don't prompt for normal/largefile changes when doing plain updates We used to get like: $ hg up -r 2 foo has been turned into a normal file keep as (l)argefile or use (n)ormal file? l getting changed largefiles 0 largefiles updated, 0 removed 0 files updated, 0 files merged, 2 files removed, 0 files unresolved $ cat foo cat: foo: No such file or directory [1] - which both asked the wrong question and did the wrong thing. Instead, skip this conflict resolution when the local conflicting file has been scheduled for removal and there thus is no conflict.

largefiles: remove extra check for file to get - it _is_ by definition in p2

largefiles: don't process merge actions at all when overwriting
