2020-06-08Fix bug with threading when cover ref is missingKonstantin Ryabitsev
When the cover letter is missing and we're starting in the middle of the thread, do not discard messages in the mbox that come before the msgid that we want. Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-06-08Fix body part parsing when '---' is not usedKonstantin Ryabitsev
If the commit message is not separated from the diff using '---' as is commonly the case, fall back to splitting by the word "diff". Reported-by: Mark Brown <broonie@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-06-08Use proper charset when reading back mailinfoKonstantin Ryabitsev
Git mailinfo output is going to be in the same character set as specified in the message headers, so we should not assume that we can read it back in unicode. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-28Don't output git am suggestion for -o -Konstantin Ryabitsev
Since we're piping out to stdout, there's obviously no reason to show what the "git am" command should be -- especially if we delete the temporary mbox file after the command completes. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-28Add --no-cover and -o - to output to stdoutKonstantin Ryabitsev
By request, provide a way to output the results of b4 am to stdout. This way it can be piped straight to "git am". E.g.: b4 diff 20200526205322.23465-1-mic@digikod.net -o - | git am Requested-by: Rob Herring <robh@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-26Use unicode escape sequencesKonstantin Ryabitsev
Let's keep our code sources in plain old ascii. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-26Up the version to 0.5.1-devKonstantin Ryabitsev
Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-25Prepare for 0.5.0v0.5.0Konstantin Ryabitsev
I think it's time to have more people poking at the diff functionality. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-25Backfill series before diffing themKonstantin Ryabitsev
Make sure we a) attempt to backfill the series if they are incomplete, b) error out if the series is incomplete anyway Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-25Add -3 to "b4 am" to prep for a 3way mergeKonstantin Ryabitsev
The original code used for b4 diff was to prepare for a 3-way merge by making sure that all blob indexes exist in the local repo. Add this functionality to "b4 am" and document all the features added in the 0.5.0 branch. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-22Suggest what to do when auto-find failsKonstantin Ryabitsev
When we can't auto-find the previous version (usually because the cover letter subject changes), suggest what to do: run b4 am -T and b4 diff on both mboxes. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-22Add ability to diff arbitrary mbox filesKonstantin Ryabitsev
Sometimes we are unable to properly look up previous series -- usually because the cover letter title changes. For those cases, it is now possible to diff two arbitrary mbox files prepared with "b4 am -T". There's also a smattering of other fixes in there because I'm too lazy to properly stage my patches. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-21Do not crash when versions are specifiedKonstantin Ryabitsev
Also, make sure we display which versions we are diffing. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-19Display range-diff by defaultKonstantin Ryabitsev
Don't make developers do copy-pasting unnecessarily. Switch to outputting the diff by default, with flag options to save to file or just show what needs to be done. Additionally, adds caching to lookups and remember previously generated fake-am ranges so we don't continuously generate loose objects on repeat runs. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-15Don't try to compare version to itselfKonstantin Ryabitsev
Need to figure this out earlier, but at least don't try to compare two versions to itself. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-15Initial implementation of b4 diffKonstantin Ryabitsev
Based on feedback from Jason Gunthorpe, implement diffing of series by creating fake git-am commit ranges. Here's an easy example: b4 diff 20200511192156.1618284-1-mic@digikod.net Suggested-by: Jason Gunthorpe <jgg@ziepe.ca> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-15Relax branch sanity-checking logicKonstantin Ryabitsev
Git has a lot of internal logic matching free-form branch names to actual branches, so don't try to second-guess what it finds acceptable. Reported-by: Mark Brown <broonie@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-15Document changes to -PKonstantin Ryabitsev
Add changes to -P,--cherry-pick to the man page. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-15Expand use of --cherry-pick ("this", globbing)Konstantin Ryabitsev
In addition to numerical ranges, -P is now also able to do: - "-P _" to grab just the msgid used with "b4 am" - "-P *glob*" to filter by commit message subject Suggested-by: Rob Herring <robh@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-13Don't fail when a message uses a weird charsetKonstantin Ryabitsev
Found via auto-testing in: https://lore.kernel.org/linux-sgx/20200421215316.56503-13-jarkko.sakkinen@linux.intel.com/raw This is wrong on many levels: Content-Type: text/plain; charset=a Assume utf-8 when something like this happens and don't fail.

2020-05-13Fix crasher for incomplete threadsKonstantin Ryabitsev
Don't crash if the message in the References: is not available in the thread. Reported-by: Bjorn Helgaas <helgaas@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-11Make sure to always use the full refnameKonstantin Ryabitsev
Git will try to helpfully disambiguate, but we just need consistency, so always ask for a full refname. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-11Deal with cases when [branch] is not specifiedKonstantin Ryabitsev
Not all local branches are going to have matching [branch] entries -- sometimes there is only a [remote]. Deal with both cases. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-11Do not match everything in -a, only -sKonstantin Ryabitsev
While trying to be more permissive with messages selected manually with -s, we broke auto-thankanator by making it match everything. Reported-by: Mark Brown <broonie@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-08Update documentation for am -P, ty -s/-d changesKonstantin Ryabitsev
- we are now using ranges for ty -s/-d - add am -P documentation for cherry-picking subsets of patches Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-07Add -P,--cherry-pick option to "b4 am"Konstantin Ryabitsev
This lets someone select a subset of patches in a series, e.g.: b4 am -P 1-3,5,7- [msgid] Suggested-by: Heiko Stübner <heiko@sntech.de> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-07Match applied patches using message-idKonstantin Ryabitsev
Track message-id for each patch and try to apply to the Link: or Message-Id: trailers, if we find them. Suggested-by: Jason Gunthorpe <jgg@ziepe.ca> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-07Improve remote/branch mappingKonstantin Ryabitsev
Our mapping of local to remote branches was very naive and failed when remote names didn't exactly match heads. Improve it using suggestions from Will Deacon.

2020-05-07Switch ty -s and -d to allow friendly rangesKonstantin Ryabitsev
Instead of insisting that people put in specific numbers, allow them to specify ranges, such as: b4 ty -s 1-3,5,7- Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-07Do not crash when thread is incompleteKonstantin Ryabitsev
Do not try to calculate indexes on a missing patch in an incomplete thread. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-07Remove QP encoding when getting fromnameKonstantin Ryabitsev
Make sure we get the clean header value when we store fromname. Link: https://linux.kernel.org/g/tools/message/142 Reported-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-05-01Check if mbox applies to current treeKonstantin Ryabitsev
Check if all patches in the mbox would apply cleanly to the current tree: - find index hash..hash information in each patch - check if git-hash-object shows exact same hashes for the current tree - if not, try the last 10 tags to see if any of them would be a good base-commit for the patch/series Not sure how useful the latter part it, but it hopefully shouldn't slow down regular operations, so I'm going to leave it in for now. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-04-27Parse body parts into usual chunksKonstantin Ryabitsev
Do a better job parsing a patch message into usual body parts: - git headers (From:, Subject:, Date:) - commit message - trailers - basement (under the ---\n) - signature (under the --\s\n) This allows us to create better reply quotes. Reported-by: Martin K. Petersen <martin.petersen@oracle.com> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>

2020-04-24Prepare for 0.4.0 releaseKonstantin Ryabitsev
It's time to graduate to 0.4.0 with these features. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-04-24Use "local tree" instead of "undefined"Konstantin Ryabitsev
This is our fail-through treename, so if we weren't able to figure out anything about it, then call it a "local tree" instead of "undefined". Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-04-22Properly deal with merge to non-current branchKonstantin Ryabitsev
When running rev-list, be mindful of which branch we need to operate on, otherwise it always runs on the current branch. Reported-by: Mark Brown <broonie@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-04-20Use the cover for backfills when availableKonstantin Ryabitsev
When we have a cover letter, use that for backfill purposes, instead of finding the first non-None patch. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-04-20Support file delete patches and binary patchesKonstantin Ryabitsev
Git's file delete patches don't contain hunks, so we weren't properly processing them for attestation (and for b4 am). While fixing that, I also added attestation support for binary patches. Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-04-17Expand templates with ${branch} and ${treename}Konstantin Ryabitsev
You can use ${branch} and ${treename} (if you set b4.thanks-treename). See .example files on some hints on how to use them. Suggested-by: Mark Brown <broonie@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-04-15Changes to b4 ty based on developer feedbackKonstantin Ryabitsev
- Properly expand ~ and env vars like $HOME in template paths - Allow partial matching of series (with a warning) - Allow using remote branches with -b - Always fall back to subject matching for patches - Tweak to the summary output Suggested-by: Mark Brown <broonie@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-04-15Properly deal with diffs that delete all linesKonstantin Ryabitsev
We weren't properly handling special diffs that deleted entire file contents (e.g. by deleting a file). Reported-by: Mark Brown <broonie@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-04-15Don't break on @@ -N,N +N @@ diff linesKonstantin Ryabitsev
When a commit is a new file with only one line, the diff output is different, so handle it without breaking. Reported-by: Mark Brown <broonie@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-04-15Keep track of how many messages we createKonstantin Ryabitsev
Don't tell us to run git send-email when there's nothing to send. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-04-15Get info from gecos if we don't have user.nameKonstantin Ryabitsev
Git gets user.name from gecos if it's not specified in user.name, so let's do the same thing. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-04-15Be more useful during non-auto matchingKonstantin Ryabitsev
Instead of bailing out when we can't find a match for a series, skip it and move to the next one in the queue. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-04-15Switch to using patchwork-compatible hashesKonstantin Ryabitsev
Using strict attestation hashes for auto-thankinator is problematic, because "git am" uses a certain degree of fuzzing, so when we try to find applied patches by running "git diff" on actual commits, line counts may not be bit-for-bit identical. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-04-10Document b4 ty and add template examplesKonstantin Ryabitsev
Still a bit slim on documentation, but this is better than nothing. I need to write a better README file that will introduce maintainers to most useful functionality aspects of b4. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-04-10Use ~/.signature if it exists for tpt defaultsKonstantin Ryabitsev
If we find a ~/.signature, then use it for making a default ${signature} value, otherwise make a "Name <email>" boring one. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
