2020-09-09Preserve trailer order by defaultKonstantin Ryabitsev
Per discussion on the users list, preserve the trailer order by default. There is no agreement on whether this is a hard requirement for patches or not, but there is general consensus that the default should be to make as few changes to incoming patches as possible. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-09-09Use shorter cache file namesKonstantin Ryabitsev
Use shorter cache filenames to avoid running into OSError. Reported-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-09-09Remove redundant backslash escapes in regexesKonstantin Ryabitsev
PyCharm thinks they are redundant, and they indeed appear to be. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-08-18Require that a trailer is at least 2 chars longKonstantin Ryabitsev
I can't think of any trailers that are shorter than 2 characters, so tweak the regex to avoid one of the possible false positives. Reported-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-08-18Cover letters may not have a diffstatKonstantin Ryabitsev
Don't check if a potential cover letter has a diffstat when processing follow-up trailers. Reported-by: Greg Kroah-Hartman <greg@kroah.com> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-07-27Fix some of the more common trailer wrappingKonstantin Ryabitsev
When copypasting patches into mail clients, trailers sometimes get mangled due to MUAs helpfully breaking long lines. Not sure if this causes more harm than good, but let's try to run some tests with this. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-07-27Fix handling of single-paragraph commit message bodiesKyle Meyer
The get_body_parts() method added in ba6c790 (Parse body parts into usual chunks, 2020-04-27) strips lines that look like trailers from the last paragraph, storing the other lines to add back to the message. However, if the commit message has only a single paragraph, get_body_parts() returns early, unconditionally returning an empty string for the message even if non-trailer lines were encountered. Return the collected non-trailer lines, if any, as the message. Signed-off-by: Kyle Meyer <kyle@kyleam.com> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-07-27Fix basement detection for empty commit message bodiesKyle Meyer
The get_body_parts() method added in ba6c790 (Parse body parts into usual chunks, 2020-04-27) splits the commit message body on "\n---\n" and takes the second half as the "basement" of the patch. The body is stripped of flanking new lines, though, so a delimiter beginning with a new line isn't appropriate for commit messages without a message body. Make the starting new line optional. Note that this doesn't matter in the end in terms of the final applied patch. Before 31f33fd (Fix body part parsing when '---' is not used, 2020-06-08), the expected patch output was produced despite the diff lines being processed as the message body. After that commit, the information following the triple dash is a bit off, but it doesn't matter because git discards it anyway.

2020-07-27Support mbox -m to be a maildirKonstantin Ryabitsev
It's a simple if/else to support maildirs for local operations, so let's handle mbox -m to be a maildir. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-07-07man: Update commit url mask to contain 12 chars of IDTudor Ambarus
Use 12 characters for the commit ID, similar to what git log --oneline uses. 10 chars of ID is sometimes not enough and git.kernel.org returns "Bad object ID". Example: https://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux.git/commit/?id=482dcb2a04 Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>

Fix a crash when multiple patches fail attestation. Also fixes fancy chechmarks. Reported-by: Christian Brauner <christian.brauner@ubuntu.com> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-07-06Deal with [PATCHvX] subjectsKonstantin Ryabitsev
Normally, we'd expect to always have a space between PATCH and other prefixes, but be forgiving if it's not present. Reported-by: Mark Brown <broonie@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-07-06Fix crash when -c used with incomplete seriesKonstantin Ryabitsev
Return early if we don't have a cover letter or patch 1/X to use as basis for the subject-based query. Reported-by: Christian Brauner <christian.brauner@ubuntu.com> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>

2020-06-10Fix regression with oddball charsetsKonstantin Ryabitsev
Fix the same bug we've fixed before in another place -- when charset is set to oddball value like charset=a, fallback to utf-8 and hope for the best. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-06-08Fix mbox naming inconsistenciesKonstantin Ryabitsev

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>

2020-05-25Backfill 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.

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>

2020-05-15Expand 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>

2020-05-01Check 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.
