* commit.h: drop redundant commentJeff King2013-07-251-2/+0
| | | | | | | | | | | | | | We mention twice that the from_ident field of struct pretty_print_context is internal. The first comment was added by 10f2fbf, which prepares the struct for internal fields, and then the second by a908047, which actually adds such a field. This was a mistake made when re-rolling the series on the list; the comment should have been removed from the latter commit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Format-patch generates emails with the "From" address set to the author of each patch. If you are going to send the emails, however, you would want to replace the author identity with yours (if they are not the same), and bump the author identity to an in-body header. Normally this is handled by git-send-email, which does the transformation before sending out the emails. However, some workflows may not use send-email (e.g., imap-send, or a custom script which feeds the mbox to a non-git MUA). They could each implement this feature themselves, but getting it right is non-trivial (one must canonicalize the identities by reversing any RFC2047 encoding or RFC822 quoting of the headers, which has caused many bugs in send-email over the years). This patch takes a different approach: it teaches format-patch a "--from" option which handles the ident check and in-body header while it is writing out the email. It's much simpler to do at this level (because we haven't done any quoting yet), and any workflow based on format-patch can easily turn it on.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the current code, callers are expected to fill in the pretty_print_context, and then the pretty.c functions simply read from it. This leaves no room for the pretty.c functions to communicate with each other by manipulating the context (e.g., data seen while printing the header may impact how we print the body). Rather than introduce a new struct to hold modifiable data, let's just drop the const-ness of the existing context struct.

When traversing a forked history like this with "git log C E": A----B----C \ D----E we ensure that A is emitted after all of B, C, D, and E are done, B has to wait until C is done, and D has to wait until E is done. In some applications, however, we would further want to control how these child commits B, C, D and E on two parallel ancestry chains are shown. Most of the time, we would want to see C and B emitted together, and then E and D, and finally A (i.e. the --topo-order output). The "lifo" parameter of the sort_in_topological_order() function is used to control this behaviour. We start the traversal by knowing two commits, C and E. While keeping in mind that we also need to inspect E later, we pick C first to inspect, and we notice and record that B needs to be inspected. By structuring the "work to be done" set as a LIFO stack, we ensure that B is inspected next, before other in-flight commits we had known that we will need to inspect, e.g. E. When showing in --date-order, we would want to see commits ordered by timestamps, i.e. show C, E, B and D in this order before showing A, possibly mixing commits from two parallel histories together. When "lifo" parameter is set to false, the function keeps the "work to be done" set sorted in the date order to realize this semantics. After inspecting C, we add B to the "work to be done" set, but the next commit we inspect from the set is E which is newer than B. The name "lifo", however, is too strongly tied to the way how the function implements its behaviour, and does not describe what the behaviour _means_. Replace this field with an enum rev_sort_order, with two possible values: REV_SORT_IN_GRAPH_ORDER and REV_SORT_BY_COMMIT_DATE, and update the existing code. The mechanical replacement rule is: "lifo == 0" is equivalent to "sort_order == REV_SORT_BY_COMMIT_DATE" "lifo == 1" is equivalent to "sort_order == REV_SORT_IN_GRAPH_ORDER" Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "indegree" field in the commit object is only used while sorting a list of commits in topological order, and wasting memory otherwise. We would prefer to shrink the size of individual commit objects, which we may have to hold thousands of in-core. We could eject "indegree" field out from the commit object and represent it as a dynamic table based on the decoration infrastructure, but the decoration is meant for sparse annotation and is not a good match. Instead, let's try a different approach. - Assign an integer (commit->index) to each commit we keep in-core (reuse the space of "indegree" field for it); - When running the topological sort, allocate an array of integers in bulk (called "slab"), use the commit->index as an index into this array, and store the "indegree" information there. This does _not_ reduce the memory footprint of a commit object, but the commit->index can be used as the index to dynamically associate commits with other kinds of information as needed.

Since every caller then ends up checking for NULL and just using the commit's original buffer, anyway, we can be a bit more helpful and just return that buffer when we would have returned NULL. Since the resulting string may or may not need to be freed, we introduce a logmsg_free, which checks whether the buffer came from the commit object or not (callers either implemented the same check already, or kept two separate pointers, one to mark the buffer to be used, and one for the to-be-freed string). Pushing this logic into logmsg_* simplifies the callers, and will let future patches lazily load the commit buffer in a single place.

Make easy-to-remember --unshallow an alias for --depth=2147483647. Make upload-pack recognize this special number as infinite depth. The effect is essentially the same as before, except that upload-pack is more efficient because it does not have to traverse to the bottom anymore. The chance of a user actually wanting exactly 2147483647 commits depth, not infinite, on a repository with a history that long, is probably too small to consider. The client can learn to add or subtract one commit to avoid the special treatment when that actually happens. (*) This is the largest positive number a 32-bit signed integer can contain. JGit and older C Git store depth as "int" so both are OK with this number. Dulwich does not support shallow clone.

However, we don't want to trigger this magic if the alternate date format we got was from the "log.date" configuration; that is not sufficiently strong context for us to invoke this particular magic. To fix this, commit f4ea32f (improve reflog date/number heuristic, 2009-09-24) introduced a "date_mode_explicit" flag in rev_info. This flag is set only when we see a "--date" option on the command line, and we a vanilla date to the reflog code if the date was not explicit. Later, commit 8f8f547 (Introduce new pretty formats %g[sdD] for reflog information, 2009-10-19) added another way to show selectors, and it did not respect the date_mode_explicit flag from f4ea32f. This patch propagates the date_mode_explicit flag to the pretty-print code, which can then use it to pass the appropriate date field to the reflog code. This brings the behavior of "%gd" in line with the other formats, and means that its output is independent of any user configuration.

That's because commit_list_insert_by_date() sorts commits with descending date, but adds later entries with the same date entries last, while commit_list_insert() always inserts entries at the top. The following commit_list_sort_by_date() keeps the order of entries sharing the same date. Jeff's test case, in a repo with lots of refs, was to run: # make a new commit on top of HEAD, but not yet referenced sha1=`git commit-tree HEAD^{tree} -p HEAD </dev/null` # now do the same "connected" test that receive-pack would do git rev-list --objects $sha1 --not --all With a git.git with a ref for each revision, master needs (best of five): real 0m2.210s user 0m2.188s sys 0m0.016s And with this patch: real 0m0.480s user 0m0.456s sys 0m0.020s Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>

If we place it at the end of the log message, we would need to teach "git log" and friends to strip the signature block with an option. - Teaching new versions of "git log" and "gitk" to optionally verify and show signatures is cleaner if we structurally know where the signature block is (instead of scanning in the commit log message). - The signature needs to be stripped upon various commit rewriting operations, e.g. rebase, filter-branch, etc. They all already ignore unknown headers, but if we place signature in the log message, all of these tools (and third-party tools) also need to learn how a signature block would look like. - When we added the optional encoding header, all the tools (both in tree and third-party) that acts on the raw commit object should have been fixed to ignore headers they do not understand, so it is not like that new header would be more likely to break than extra text in the commit. A commit made with the above sample sequence would look like this: $ git cat-file commit HEAD tree 3cd71d90e3db4136e5260ab54599791c4f883b9d parent b87755351a47b09cb27d6913e6e0e17e6254a4d4 author Junio C Hamano <gitster@pobox.com> 1317862251 -0700 committer Junio C Hamano <gitster@pobox.com> 1317862251 -0700 gpgsig -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQIcBAABAgAGBQJOjPtrAAoJELC16IaWr+bL4TMP/RSe2Y/jYnCkds9unO5JEnfG ... =dt98 -----END PGP SIGNATURE----- foo but "git log" (unless you ask for it with --pretty=raw) output is not cluttered with the signature information.

Use a pointer to a strbuf instead, so that we can either choose to allow low-level plumbing commands to make commits that contain NUL byte in its message, or forbid NUL everywhere by adding the check in commit_tree(), in later patches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After running "git pull $there for-linus" to merge a signed tag, the integrator may need to amend the resulting merge commit to fix typoes in it.

Introduce a new "mergetag" multi-line header field to the commit object, and use it to store the entire contents of each signed tag merged. A commit header that has a multi-line payload begins with the header tag (e.g. "mergetag" in this case), SP, the first line of payload, LF, and all the remaining lines have a SP inserted at the beginning. In hindsight, it would have been better to make "merge --continue" as the way to continue from such an interrupted merge, not "commit", but this is a backward compatibility baggage we would need to carry around for now.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The merge-recursive code uses the commit->util field directly to annotate the commit objects given from the command line, i.e. the remote heads to be merged, with a single string to be used to describe it in its trace messages and conflict markers. Correct this short-signtedness by redefining the field to be a pointer to a structure "struct merge_remote_desc" that later enhancements can add more information. Store the original objects we were told to merge in a field "obj" in this struct, so that we can recover the tag we were told to merge. Signed-off-by: Junio C Hamano <gitster@pobox.com>
