2021-12-13tests: fix broken &&-chains in `{...}` groupsEric Sunshine
The top-level &&-chain checker built into t/ causes tests to magically exit with code 117 if the &&-chain is broken. However, it has the shortcoming that the magic does not work within `{...}` groups, `(...)` subshells, `$(...)` substitutions, or within bodies of compound statements, such as `if`, `for`, `while`, `case`, etc. `chainlint.sed` partly fills in the gap by catching broken &&-chains in `(...)` subshells, but bugs can still lurk behind broken &&-chains in the other cases. Fix broken &&-chains in `{...}` groups in order to reduce the number of possible lurking bugs. Signed-off-by: Eric Sunshine <> Reviewed-by: Elijah Newren <> Signed-off-by: Junio C Hamano <>
2021-05-04trailer: add new .cmd config optionZheNing Hu
The `trailer.<token>.command` configuration variable specifies a command (run via the shell, so it does not have to be a single name or path to the command, but can be a shell script), and the first occurrence of substring $ARG is replaced with the value given to the `interpret-trailer` command for the token in a '--trailer <token>=<value>' argument. This has three downsides: * The use of $ARG in the mechanism misleads the users that the value is passed in the shell variable, and tempt them to use $ARG more than once, but that would not work, as the second and subsequent $ARG are not replaced. * Because $ARG is textually replaced without regard to the shell language syntax, even '$ARG' (inside a single-quote pair), which a user would expect to stay intact, would be replaced, and worse, if the value had an unmatched single quote (imagine a name like "O'Connor", substituted into NAME='$ARG' to make it NAME='O'Connor'), it would result in a broken command that is not syntactically correct (or worse). * The first occurrence of substring `$ARG` will be replaced with the empty string, in the command when the command is first called to add a trailer with the specified <token>. This is a bad design, the nature of automatic execution causes it to add a trailer that we don't expect. Introduce a new `trailer.<token>.cmd` configuration that takes higher precedence to deprecate and eventually remove `trailer.<token>.command`, which passes the value as an argument to the command. Instead of "$ARG", users can refer to the value as positional argument, $1, in their scripts. At the same time, in order to allow `git interpret-trailers` to better simulate the behavior of `git command -s`, 'trailer.<token>.cmd' will not automatically execute.

2019-06-19interpret-trailers: load default configJeff King
The interpret-trailers program does not do the usual loading of config via git_default_config(), and thus does not respect many of the usual options. In particular, we will not load core.commentChar, even though the underlying trailer code uses its value. This can be seen in the accompanying test, where setting core.commentChar to anything besides "#" results in a failure to treat the comments correctly.

2018-08-23interpret-trailers: allow suppressing "---" dividerJeff King
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 boundaryJeff King
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 an option to unfold valuesJeff King
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. Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>
2017-08-15interpret-trailers: add an option to show only existing trailersJeff King
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. Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>
2017-08-15interpret-trailers: add an option to show only the trailersJeff King
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 <> Signed-off-by: Junio C Hamano <>
2017-08-14interpret-trailers: add options for actionsPaolo Bonzini
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.

2017-05-18interpret-trailers: honor the cut lineBrian Malehorn
If a commit message is edited with the "verbose" option, the buffer will have a cut line and diff after the log message, like so: my subject # ------------------------ >8 ------------------------ # Do not touch the line above. # Everything below will be removed. diff --git a/foo.txt b/foo.txt index 5716ca5..7601807 100644 --- a/foo.txt +++ b/foo.txt @@ -1 +1 @@ -bar +baz "git interpret-trailers" is unaware of the cut line, and assumes the trailer block would be at the end of the whole thing. This can easily be seen with: $ GIT_EDITOR='git interpret-trailers --in-place --trailer Acked-by:me' \ git commit --amend -v Teach "git interpret-trailers" to notice the cut-line and ignore the remainder of the input when looking for a place to add new trailer block. This makes it consistent with how "git commit -v -s" inserts a new Signed-off-by: line. This can be done by the same logic as the existing helper function, wt_status_truncate_message_at_cut_line(), uses, but it wants the caller to pass a strbuf to it. Because the function ignore_non_trailer() used by the command takes a <pointer, length> pair, not a strbuf, steal the logic from wt_status_truncate_message_at_cut_line() to create a new wt_status_locate_end() helper function that takes <pointer, length> pair, and make ignore_non_trailer() call it to help "interpret-trailers". Since there is only one caller of wt_status_truncate_message_at_cut_line() in cmd_commit(), rewrite it to call wt_status_locate_end() helper instead and remove the old helper that no longer has any caller.

2016-10-21trailer: support values folded to multiple linesJonathan Tan
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: forbid leading whitespace in trailersJonathan Tan

2016-10-21trailer: allow non-trailers in trailer blockJonathan Tan
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.

2015-08-31trailer: support multiline titleChristian Couder
We currently ignore the first line passed to `git interpret-trailers`, when looking for the beginning of the trailers. Unfortunately this does not work well when a commit is created with a line break in the title, using for example the following command: git commit -m 'place of code: change we made' That's why instead of ignoring only the first line, it is better to ignore the first paragraph.

2015-08-21trailer: ignore first line of messageChristian Couder
When looking for the start of the trailers in the message we are passed, we should ignore the first line of the message. The reason is that if we are passed a patch or commit message then the first line should be the patch title. If we are passed only trailers we can expect that they start with an empty line that can be ignored too. This way we can properly process commit messages that have only one line with something that looks like a trailer, for example like "area of code: change we made".
