2011-05-26format-patch: preserve subject newlines with -kLibravatar Jeff King1-1/+2
In older versions of git, we used rfc822 header folding to indicate that the original subject line had multiple lines in it. But since a1f6baa (format-patch: wrap long header lines, 2011-02-23), we now use header folding whenever there is a long line. This means that "git am" cannot trust header folding as a sign from format-patch that newlines should be preserved. Instead, format-patch needs to signal more explicitly that the newlines are significant. This patch does so by rfc2047-encoding the newlines in the subject line. No changes are needed on the "git am" end; it already decodes the newlines properly. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-05-26clean up calling conventions for pretty.c functionsLibravatar Jeff King1-52/+47
We have a pretty_print_context representing the parameters for a pretty-print session, but we did not use it uniformly. As a result, functions kept growing more and more arguments. Let's clean this up in a few ways: 1. All pretty-print pp_* functions now take a context. This lets us reduce the number of arguments to these functions, since we were just passing around the context values separately. 2. The context argument now has a cmit_fmt field, which was passed around separately. That's one less argument per function. 3. The context argument always comes first, which makes calling a little more uniform. This drops lines from some callers, and adds lines in a few places (because we need an extra line to set the context's fmt field). Overall, we don't save many lines, but the lines that are there are a lot simpler and more readable. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-05-25userformat_find_requirements(): find requirement for the correct formatLibravatar Junio C Hamano1-1/+1
This function was introduced in 5b16360 (pretty: Initialize notes if %N is used, 2010-04-13) to check what kind of information the "log --format=..." user format string wants. The function can be passed a NULL instead of a format string to ask it to check user_format variable kept by an earlier call to save_user_format(). But it unconditionally checked user_format and not the string it was given. The only caller introduced by the change passes NULL, which kept the bug unnoticed, until a new GCC noticed that there is an assignment to fmt that is never used.

2011-04-26pretty: quote rfc822 specials in email addressesLibravatar Jeff King1-1/+60
If somebody has a name that includes an rfc822 special, we will output it literally in the "From:" header. This is usually OK, but certain characters (like ".") are supposed to be enclosed in double-quotes in a mail header. In practice, whether this matters may depend on your MUA. Some MUAs will happily take in: From: Foo B. Bar <author@example.com> without quotes, and properly quote the "." when they send the actual mail. Others may not, or may screw up harder things like: From: Foo "The Baz" Bar <author@example.com> For example, mutt will strip the quotes, thinking they are actual syntactic rfc822 quotes. So let's quote properly, and then (if necessary) we still apply rfc2047 encoding on top of that, which should make all MUAs happy.

2011-04-14format-patch: wrap email addresses after long namesLibravatar Jeff King1-0/+9
We already wrap names in "from" headers, which tend to be the long part of an address. But it's also possible for a long name to not be wrapped, but to make us want to wrap the email address. For example (imagine for the sake of readability we want to wrap at 50 characters instead of 78): From: this is my really long git name <foo@example.com> The name does not overflow the line, but the name and email together do. So we would rather see: From: this is my really long git name <git@example.com> Because we wrap the name separately during add_rfc2047, we neglected this case. Instead, we should see how long the final line of the wrapped name ended up, and decide whether or not to wrap based on that. We can't break the address into multiple parts, so we either leave it with the name, or put it by itself on a line. Test by Erik Faye-Lund.

2011-02-23format-patch: wrap long header linesLibravatar Jeff King1-8/+24
Subject and identity headers may be arbitrarily long. In the past, we just assumed that single-line headers would be reasonably short. For multi-line subjects that we squish into a single line, we just "pre-folded" the data in pp_title_line by adding a newline and indentation. There were two problems. One is that, although rare, single-line messages can actually be longer than the recommended line-length limits. The second is that the pre-folding interacted badly with rfc2047 encoding, leading to malformed headers. Instead, let's stop pre-folding the subject lines, and just fold everything based on length in add_rfc2047, whether it is encoded or not.

Without this patch at least IBM VisualAge C 5.0 (I have 5.0.2) on AIX 5.1 fails to compile git. enum style is inconsistent already, with some enums declared on one line, some over 3 lines with the enum values all on the middle line, sometimes with 1 enum value per line... and independently of that the trailing comma is sometimes present and other times absent, often mixing with/without trailing comma styles in a single file, and sometimes in consecutive enum declarations. Clearly, omitting the comma is the more portable style, and this patch changes all enum declarations to use the portable omitted dangling comma style consistently. Signed-off-by: Gary V.

2010-05-03pretty: add aliases for pretty formatsLibravatar Will Palmer1-2/+55
previously the only ways to alias a --pretty format within git were either to set the format as your default format (via the format.pretty configuration variable), or by using a regular git alias. This left the definition of more complicated formats to the realm of "builtin or nothing", with user-defined formats usually being reserved for quick one-offs. Here we allow user-defined formats to enjoy more or less the same benefits of builtins. By defining pretty.myalias, "myalias" can be used in place of whatever would normally come after --pretty=. This can be a format:, tformat:, raw (ie, defaulting to tformat), or the name of another builtin or user-defined pretty format.

As the first step towards creating aliases, we make it easier to add new formats to the list of builtin formats. To do this, we move the initialization of the formats array into a new function, setup_commit_formats(), which we can easily extend later. Then, rather than looping through only the list of known formats, we make a more generic find_commit_format function, which will return the commit format whose name is the shortest which is prefixed with the passed-in sought format, the same rules which were more-or-less hard-coded in before.

Giving "Notes" information in the default output format of "log" and "show" is a sensible progress (the user has asked for it by having the notes), but for some commands (e.g. "format-patch") spewing notes into the formatted commit log message without being asked is too aggressive. Enable notes output only for "log", "show", "whatchanged" by default and only when the user didn't ask any specific --pretty/--format from the command line; users can explicitly override this default with --show-notes and --no-notes option.

Add three new --pretty=format escapes: %gD long reflog descriptor (e.g. refs/stash@{0}) %gd short reflog descriptor (e.g. stash@{0}) %gs reflog message This is achieved by passing down the reflog info, if any, inside the pretty_print_context struct. We use the newly refactored get_reflog_selector(), and give it some extra functionality to extract a shortened ref. The shortening is cached inside the commit_reflogs struct; the only allocation of it happens in read_complete_reflog(), where it is initialised to 0. Also add another helper get_reflog_message() for the message extraction. Note that the --format="%h %gD: %gs" tests may not work in real repositories, as the --pretty formatter doesn't know to leave away the ": " on the last commit in an incomplete (because git-gc removed the old part) reflog. This equivalence is nevertheless the main goal of this patch. Thanks to Jeff King for reviews, the %gd testcase and documentation.

Commit notes are blobs which are shown together with the commit message. These blobs are taken from the notes ref, which you can configure by the config variable core.notesRef, which in turn can be overridden by the environment variable GIT_NOTES_REF. The notes ref is a branch which contains "files" whose names are the names of the corresponding commits (i.e. the SHA-1). The rationale for putting this information into a ref is this: we want to be able to fetch and possibly union-merge the notes, maybe even look at the date when a note was introduced, and we want to store them efficiently together with the other objects. This patch has been improved by the following contributions: - Thomas Rast: fix core.notesRef documentation - Tor Arne Vestbø: fix printing of multi-line notes - Alex Riesen: Using char array instead of char pointer costs less BSS - Johan Herland: Plug leak when msg is good, but msglen or type causes return Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Tor Arne Vestbø <tavestbo@trolltech.com> Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com> get_commit_notes(): Plug memory leak when 'if' triggers, but not because of read_sha1_file() failure

This teaches the "pretty" machinery to expand '%+x' to a LF followed by the expansion of '%x' if and only if '%x' expands to a non-empty string, and to remove LFs before '%-x' if '%x' expands to an empty string. This works for any supported expansion placeholder 'x'. This is expected to be immediately useful to reproduce the commit log message with "%s%+b%n"; "%s%n%b%n" adds one extra LF if the log message is a one-liner.
