"git interpret-trailers" and its underlying machinery had a buggy code that attempted to ignore patch text after commit log message, which triggered in various codepaths that will always get the log message alone and never get such an input. * jk/trailer-fixes: append_signoff: use size_t for string offsets sequencer: ignore "---" divider when parsing trailers pretty, ref-filter: format %(trailers) with no_divider option interpret-trailers: allow suppressing "---" divider interpret-trailers: tighten check for "---" patch boundary trailer: pass process_trailer_opts to trailer_info_get() trailer: use size_t for iterating trailer list trailer: use size_t for string offsets
2018-08-23interpret-trailers: allow suppressing "---" dividerLibravatar Jeff King1-1/+6
Even with the newly-tightened "---" parser, it's still possible for a commit message to trigger a false positive if it contains something like "--- foo". If the caller knows that it has only a single commit message, it can now tell us with the "--no-divider" option, eliminating any false positives. If we were designing this from scratch, I'd probably make this the default. But we've advertised the "---" behavior in the documentation since interpret-trailers has existed. Since it's meant to be scripted, breaking that would be a bad idea. Note that the logic is in the underlying trailer.c code, which is used elsewhere. The default there will keep the current behavior, but many callers will benefit from setting this new option. That's left for future patches.

2018-08-23interpret-trailers: tighten check for "---" patch boundaryLibravatar Jeff King1-2/+3
The interpret-trailers command accepts not only raw commit messages, but it also can manipulate trailers in format-patch output. That means it must find the "---" boundary separating the commit message from the patch. However, it does so by looking for any line starting with "---", regardless of whether there is further content. This is overly lax compared to the parsing done in mailinfo.c's patchbreak(), and may cause false positives (e.g., t/perf output tables uses dashes; if you cut and paste them into your commit message, it fools the parser). We could try to reuse patchbreak() here, but it actually has several heuristics that are not of interest to us (e.g., matching "diff -" without a three-dash separator or even a CVS "Index:" line). We're not interested in taking in whatever random cruft people may send, but rather handling git-formatted patches. Note that the existing documentation was written in a loose way, so technically we are changing the behavior from what it said. But this should implement the original intent in a more accurate way.

2017-08-15interpret-trailers: add --parse convenience optionLibravatar Jeff King1-7/+14
The last few commits have added command line options that can turn interpret-trailers into a parsing tool. Since they'd most often be used together, let's provide a convenient single option for callers to invoke this mode. This is implemented as a callback rather than a boolean so that its effect is applied immediately, as if those options had been specified. Later options can then override them. E.g.: git interpret-trailers --parse --no-unfold would work. Let's also update the documentation to make clear that this parsing mode behaves quite differently than the normal "add trailers to the input" mode.

2017-08-15interpret-trailers: add an option to unfold valuesLibravatar Jeff King1-0/+4
The point of "--only-trailers" is to give a caller an output that's easy for them to parse. Getting rid of the non-trailer material helps, but we still may see more complicated syntax like whitespace continuation. Let's add an option to unfold any continuation, giving the output as a single "key: value" line per trailer. As a bonus, this could be used even without --only-trailers to clean up unusual formatting in the incoming data.

2017-08-15interpret-trailers: add an option to show only existing trailersLibravatar Jeff King1-0/+5
It can be useful to invoke interpret-trailers for the primary purpose of parsing existing trailers. But in that case, we don't want to apply existing ifMissing or ifExists rules from the config. Let's add a special mode where we avoid applying those rules. Coupled with --only-trailers, this gives us a reasonable parsing tool.

2017-08-15interpret-trailers: add an option to show only the trailersLibravatar Jeff King1-0/+3
In theory it's easy for any reader who wants to parse trailers to do so. But there are a lot of subtle corner cases around what counts as a trailer, when the trailer block begins and ends, etc. Since interpret-trailers already has our parsing logic, let's let callers ask it to just output the trailers. They still have to parse the "key: value" lines, but at least they can ignore all of the other corner cases. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Allow using non-default values for trailers without having to set them up in .gitconfig first. For example, if you have the following configuration trailer.signed-off-by.where = end you may use "--where before" when a patch author forgets his Signed-off-by and provides it in a separate email. Likewise for --if-exists and --if-missing Reverting to the behavior specified by .gitconfig is done with --no-where, --no-if-exists and --no-if-missing.

2016-11-21doc: mention user-configured trailersLibravatar Jonathan Tan1-1/+2
In commit 1462450 ("trailer: allow non-trailers in trailer block", 2016-10-21), functionality was added (and tested [1]) to allow non-trailer lines in trailer blocks, as long as those blocks contain at least one Git-generated or user-configured trailer, and consists of at least 25% trailers. The documentation was updated to mention this new functionality, but did not mention "user-configured trailer". Further update the documentation to also mention "user-configured trailer".

2016-10-21trailer: support values folded to multiple linesLibravatar Jonathan Tan1-3/+4
Currently, interpret-trailers requires that a trailer be only on 1 line. For example: a: first line second line would be interpreted as one trailer line followed by one non-trailer line.

2016-10-21trailer: allow non-trailers in trailer blockLibravatar Jonathan Tan1-2/+3
Currently, interpret-trailers requires all lines of a trailer block to be trailers (or comments) - if not it would not identify that block as a trailer block, and thus create its own trailer block, inserting a blank line. For example: echo -e "\nSigned-off-by: x\nnot trailer" | git interpret-trailers --trailer "c: d" would result in: Signed-off-by: x not trailer c: d Relax the definition of a trailer block to require that the trailers (i) are all trailers, or (ii) contain at least one Git-generated trailer and consists of at least 25% trailers. Signed-off-by: x not trailer c: d (i) is the existing functionality. (ii) allows arbitrary lines to be included in trailer blocks, like those in [1], and still allow interpret-trailers to be used.
