* dgit: quilt fixup: Maybe mention gitattributesIan Jackson2018-08-20
| | | | | | | | These are a potential cause of quilt linearisation failure. Closes:#906199. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* dgit(1), dgit(7): Document that we do not suppress export attributesIan Jackson2018-08-20
| | | | | | Ie, ones which affect git-archive. This is related to #906199. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* dgit: quilt fixup errors: Refactor and reword very slightlyIan Jackson2018-08-20
| | | | | | | Make this two calls to push so we can put things in between. Also remove `to specify'; now the message fits in 80 columns. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* dgit: quilt fixup: Do not suggest quilt modes if we see gdrIan Jackson2018-08-20
| | | | | | | If `stopped at' is a git-debrebase commit, then a non-default quilt mode is probably not the answer. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* dgit: quilt fiuxp: linearisation failure: Add a blank lineIan Jackson2018-08-20
| | | | | | | The `stopped at' commit report can be long, if there are several, or complicated, commits. Add a blank line. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* dgit: quilt fixup: @failsuggestion: Include a machine-readable reasonIan Jackson2018-08-20
| | | | | | | Each entry is now an arrayref. This will let quilt_fiuxp filter them later. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* dgit(7): Mention bad origs as possible cause of quilt fixup failureIan Jackson2018-08-20
| | | | | | And document our error message changes. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* dgit: quilt fixup error messages: Change hint emphasisIan Jackson2018-08-20
| | | | | | | | | * No longer hint --quilt=smash or dpkg source --commit. These are rarely the right thing. * Hint about bad origs, instead. This is fairly common. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* dgit: Remove a spurious spaceIan Jackson2018-08-20

* git-debrebase: Provide hints for unprocessable commitsIan Jackson2018-08-20
| | | | | | | | | | Depending on the apparent branch ffq state. Closes:#905005. In particular, if it doesn't look like this branch was ever used with gdr, suggest that the user is on the wrong branch, or needs to use convert-from-*. Closes:#905279. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: Introduce new `fail_unprocessable'Ian Jackson2018-08-20
| | | | | | | | | This is called when we want to call `fail' because we have found an unprocessable commit. NFC. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: convert-from-*: leave debrebase-last refsIan Jackson2018-08-19
| | | | | | | To hint to everyone that this is now a gdr branch. This will make dgit push use gdr make-patches, for example. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: begin_convert_from: Break out $gdrlast_objIan Jackson2018-08-19
| | | | | | NFC Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: Snag on repeated conversionsIan Jackson2018-08-19
| | | | | | | | | If debrebase-last says we are ahead of some previous gdr work, it is carrying on is unlikely to be helpful. It would only be sensible if the package is vacillating between branch formats, and this is reflected and visible in the branch history. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: Refuse to start conversion if ffq-prev existsIan Jackson2018-08-19
| | | | | | | Trying to rerun git-debrebase convert-from-something, on an unstitched gdr branch, would end in tears. Forbid it utterly. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: record_gdrlast: Honour $oldvalueIan Jackson2018-08-19
| | | | | | NFC for existing callers. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

| | | | | | NFC Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: Break out begin_convert_from & complete_...Ian Jackson2018-08-19
| | | | | | | | $gdrlastinfo is undef for now, and will be used in a moment. No functional change. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: Break out record_gdrlastIan Jackson2018-08-19

* git-debrebase: Merge: Put off some xxx's, making them MERGE-TODOIan Jackson2018-08-19
| | | | | | | We are going to release with this machinery in this experimental state. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: Document merged-breakwater metadata tagIan Jackson2018-08-19
| | | | | | | This is generated only by the experimental merge machinery and is subject to possible future change. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: Merge: Remove some xxx'sIan Jackson2018-08-19
| | | | | | | | | | git-debrebase(5) already has ILLEGAL OPERATIONS (which forbids many git-rebase operations) and also of course LEGAL OPERATIONS. The limitations on what kind of merges we can resolve and how will be documented when we document the merge machinery properly. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* changelog: Document changes to convert-from-gbp messages.Ian Jackson2018-08-19
| | | | | | This is part of #906641. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: convert-from-gbp: Check separately for $dtagIan Jackson2018-08-19
| | | | | | | This allows us to print a more sensible error message, Previously git would print a fatal error, after which we carry on. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: convert-from-gbp: Add a missing newline to a dieIan Jackson2018-08-19
| | | | Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: convert-from-gbp: handle missing maintainer tagIan Jackson2018-08-19
| | | | | | | | Look for / in $mtag, not in $mtag_pat. Obviously it will be in the latter. The result, before, is that we would look for a completely bogus $dtag and print daft error messages. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* test suite: gdr-import-nostitch: New testIan Jackson2018-08-19
| | | | | | | Generate this situation and check it's OK. Also check that the messages contain the expected hint. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: convert-from-gbp; on stitch failure, clarify messageIan Jackson2018-08-19
| | | | | | | | | Clarify what the preceding failure messages mean, and what the consequences are. This is part of #906641. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* test suite: gdr-convert-gbp: Break the start out into lib-gdrIan Jackson2018-08-19
| | | | | | | This will allow us to test other things to do with this conversion without making tests/setup/gdr-convert-gbp more complicated. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

* git-debrebase: convert-from-*: Snag on unused patchesIan Jackson2018-08-19
| | | | | | | | | | | Patches in d/patches which are not in series will be deleted, and not represented in the output. So call them a snag. Closes:#904997. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

* test suite: gdr-subcommands: Test raw conversion from gbpIan Jackson2018-08-19
| | | | | | | | | Make a branch which strips off the pseudomerge generated by gdr to stitch the dgit history, and then run some tests on that. These new tests detect #905975. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* test suite: gdr-subcommands: Use $peel, not $work, for a few checksIan Jackson2018-08-19
| | | | | | | | | | | | The definition of P says P result is add-patches, remaining letters apply to result~ But this was not hnoured by N n Z. Honour it. No change with existing tests, which do not follow P with any of those. But, this will be important in a moment, Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* test suite: gdr-convert-gbp: Save converted-from-gbpIan Jackson2018-08-19
| | | | | | This new branch will be useful in a moment. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: On rebase, always save ffq-prevIan Jackson2018-08-19
| | | | | | | | Even if we were both stitched and laundered. Closes:#905975. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: `prepush' is now a silent no-op if unstitched.Ian Jackson2018-08-19
| | | | | | This is more friendly. Update the docs accordingly. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* changelog: Add perf numbersIan Jackson2018-08-19
| | | | | | | | | | | | | This is from tests on my laptop with the branch the Debian kernel folks shared with me, ie c6eb63c6ed0694b0d22fbe5aaff953d209a3fc4e. avoid new runtimes in [s] before read-tree get_differs git-debrebase 78.574 3.699 1.419 git-debrebase status 3.359 unchanged 0.818 Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: Rewrite get_differs in terms of trees_diff_walkIan Jackson2018-08-19
| | | | | | | | | | | As noted, git-diff-tree is quite slow. We can do much better, by stepping across the two trees ourselves. There should be no particularly significant change: the answers should be the same for reasonable inputs. Unreasonable inputs (particularly, executable files etc.) may be handled better, even. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: get_tree: Support '' for nonexistent objectsIan Jackson2018-08-19
| | | | | | This is going to be convenient in a moment. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
* git-debrebase: New get_tree machinery: Fix debuggingIan Jackson2018-08-19
| | | | | | | | | When we localise, we get a new variable, rather than localising the binding imported from Debian::Dgit. How annoying. Also, add two new debug prints at level 3. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
