* builtin-blame: Fix blame -C -C with submodules.Alexander Gavrilov2008-10-05
| | | | | | | | | | When performing copy detection, git-blame tries to read gitlinks as blobs, which causes it to die. This patch adds a check to skip them. Signed-off-by: Alexander Gavrilov <angavrilov@gmail.com> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
* "blame -c" should be compatible with "annotate"Junio C Hamano2008-09-05
| | | | | | | | | | | There is no reason to have a separate variable cmd_is_annotate; OUTPUT_ANNOTATE_COMPAT option is supposed to produce the compatibility output, and we should produce the same output even when the command was not invoked as "annotate" but as "blame -c".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When you misuse a git command, you are shown the usage string. But this is currently shown in the dashed form. So if you just copy what you see, it will not work, when the dashed form is no longer supported. This patch makes git commands show the dash-less version.

The previous revision machinery update to decorate each commit with its children was leading to this change. When the --reverse option is given, we read the old version and pass blame to the children of the current suspect, instead of the usual order of starting from the latest and passing blame to parents. The standard yardstick of "blame" in git.git history is "rev-list.c" which was refactored heavily in its existence. For example: git blame -C -C -w --reverse 9de48752..master -- rev-list.c begins like this: 6c41b801 builtin-rev-list.c (JC Hamano 2008-04-02 1) #include "cache... 6c41b801 builtin-rev-list.c (JC Hamano 2008-04-02 2) #include "commi... 6c41b801 builtin-rev-list.c (JC Hamano 2008-04-02 3) #include "tree.... 6c41b801 builtin-rev-list.c (JC Hamano 2008-04-02 4) #include "blob.... 213523f4 rev-list.c (JC Hamano 2006-03-01 5) #include "epoch... 6c41b801 builtin-rev-list.c (JC Hamano 2008-04-02 6) ab57c8dd rev-list.c (JC Hamano 2006-02-24 7) #define SEEN ab57c8dd rev-list.c (JC Hamano 2006-02-24 8) #define INTERES... 213523f4 rev-list.c (JC Hamano 2006-03-01 9) #define COUNTED... 7e21c29b rev-list.c (LTorvalds 2005-07-06 10) #define SHOWN ... 6c41b801 builtin-rev-list.c (JC Hamano 2008-04-02 11) 6c41b801 builtin-rev-list.c (JC Hamano 2008-04-02 12) static const ch... b1349229 rev-list.c (LTorvalds 2005-07-26 13) "usage: git-... This reveals that the original first four lines survived until now in builtin-rev-list.c , inclusion of "epoch.h" was removed after 213523f4 while the contents was still in rev-list.c. This mode probably needs more tweaking so that the commit that removed the line (i.e. the children of the commits listed in the above sample output) is shown instead to be useful, but then there is a little matter of which child of a fork point to show. For now, you can find the diff that rewrote the fifth line above by doing: $ git log --children 213523f4^.. to find its child, which is 1025fe5 (Merge branch 'lt/rev-list' into next, 2006-03-01), and then look at that child with: $ git show 1025fe5 Signed-off-by: Junio C Hamano <gitster@pobox.com>
| * builtin-blame.c: allow more than 16 parentsJunio C Hamano2008-04-12
| | | | | | | | | | | | | | | | | | | | | | This removes the hardcoded 16 parents limit from git-blame by allowing the parent array to be allocated dynamically. As the ultimate objective is not about allowing dodecapus, but about annotating the history upside down, it also renames "parent" in the code to "scapegoat"; the name of the game used to be "pass blame to your parents", but now it is "find a scapegoat to pass blame on".

* Avoid unnecessary "if-before-free" tests.Jim Meyering2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change removes all obvious useless if-before-free tests. E.g., it replaces code like this: if (some_expression) free (some_expression); with the now-equivalent: free (some_expression); It is equivalent not just because POSIX has required free(NULL) to work for a long time, but simply because it has worked for so long that no reasonable porting target fails the test. Here's some evidence from nearly 1.5 years ago: http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html FYI, the change below was prepared by running the following: git ls-files -z | xargs -0 \ perl -0x3b -pi -e \ 's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s' Note however, that it doesn't handle brace-enclosed blocks like "if (x) { free (x); }". But that's ok, since there were none like that in git sources. Beware: if you do use the above snippet, note that it can produce syntactically invalid C code. That happens when the affected "if"-statement has a matching "else". E.g., it would transform this if (x) free (x); else foo (); into this: free (x); else foo (); There were none of those here, either. If you're interested in automating detection of the useless tests, you might like the useless-if-before-free script in gnulib: [it *does* detect brace-enclosed free statements, and has a --name=S option to make it detect free-like functions with different names] http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

| * | safecrlf: Add mechanism to warn about irreversible crlf conversionsSteffen Prohaska2008-02-06
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CRLF conversion bears a slight chance of corrupting data. autocrlf=true will convert CRLF to LF during commit and LF to CRLF during checkout. A file that contains a mixture of LF and CRLF before the commit cannot be recreated by git. For text files this is the right thing to do: it corrects line endings such that we have only LF line endings in the repository. But for binary files that are accidentally classified as text the conversion can corrupt data. If you recognize such corruption early you can easily fix it by setting the conversion type explicitly in .gitattributes. Right after committing you still have the original file in your work tree and this file is not yet corrupted. You can explicitly tell git that this file is binary and git will handle the file appropriately. Unfortunately, the desired effect of cleaning up text files with mixed line endings and the undesired effect of corrupting binary files cannot be distinguished. In both cases CRLFs are removed in an irreversible way. For text files this is the right thing to do because CRLFs are line endings, while for binary files converting CRLFs corrupts data. This patch adds a mechanism that can either warn the user about an irreversible conversion or can even refuse to convert. The mechanism is controlled by the variable core.safecrlf, with the following values: - false: disable safecrlf mechanism - warn: warn about irreversible conversions - true: refuse irreversible conversions The default is to warn. Users are only affected by this default if core.autocrlf is set. But the current default of git is to leave core.autocrlf unset, so users will not see warnings unless they deliberately chose to activate the autocrlf mechanism. The safecrlf mechanism's details depend on the git command. The general principles when safecrlf is active (not false) are: - we warn/error out if files in the work tree can modified in an irreversible way without giving the user a chance to backup the original file. - for read-only operations that do not modify files in the work tree we do not not print annoying warnings. There are exceptions. Even though... - "git add" itself does not touch the files in the work tree, the next checkout would, so the safety triggers; - "git apply" to update a text file with a patch does touch the files in the work tree, but the operation is about text files and CRLF conversion is about fixing the line ending inconsistencies, so the safety does not trigger; - "git diff" itself does not touch the files in the work tree, it is often run to inspect the changes you intend to next "git add". To catch potential problems early, safety triggers. The concept of a safety check was originally proposed in a similar way by Linus Torvalds. Thanks to Dimitry Potapov for insisting on getting the naked LF/autocrlf=true case right. Signed-off-by: Steffen Prohaska <prohaska@zib.de>
* | Make on-disk index representation separate from in-core oneLinus Torvalds2008-01-21
|/ | | | | | | | | | | | | | | | This converts the index explicitly on read and write to its on-disk format, allowing the in-core format to contain more flags, and be simpler. In particular, the in-core format is now host-endian (as opposed to the on-disk one that is network endian in order to be able to be shared across machines) and as a result we can dispense with all the htonl/ntohl on accesses to the cache_entry fields. This will make it easier to make use of various temporary flags that do not exist in the on-disk format. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This patch releases the blob after we ran diff between the child rev and its parents. When passing blame from a parent to its parent (i.e. the grandparent), the blob data for the parent may need to be read again, but it should be relatively cheap, thanks to delta-base cache.

Now instead of asking for quotes or not, you pass a "terminator". If it's \0 then we assume you don't want to escape, else C escaping is performed. In any case, the terminator is also appended to the stream. It also no longer takes the prefix/prefix_len arguments, as it's seldomly used, and makes some optimizations harder. * write_name_quotedpfx is created to work like write_name_quoted and take the prefix/prefix_len arguments. Thanks to those API changes, diff.c has somehow lost weight, thanks to the removal of functions that were wrappers around the old write_name_quoted trying to give it a semantics like the new one, but performing a lot of allocations for this goal. Now we always write directly to the stream, no intermediate allocation is performed. As a side effect of the refactor in builtin-apply.c, the length of the bar graphs in diffstats are not affected anymore by the fact that the path was clipped.

* Don't fflush(stdout) when it's not helpfulTheodore Ts'o2007-06-30
| | | | | | | | | | | | | | | | | | | | | | This patch arose from a discussion started by Jim Meyering's patch whose intention was to provide better diagnostics for failed writes. Linus proposed a better way to do things, which also had the added benefit that adding a fflush() to git-log-* operations and incremental git-blame operations could improve interactive respose time feel, at the cost of making things a bit slower when we aren't piping the output to a downstream program. This patch skips the fflush() calls when stdout is a regular file, or if the environment variable GIT_FLUSH is set to "0". This latter can speed up a command such as: GIT_FLUSH=0 strace -c -f -e write time git-rev-list HEAD | wc -l a tiny amount.

| * blame: -C -C -CJunio C Hamano2007-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When you do this, existing "blame -C -C" would not find that the latter half of the file2 came from the existing file1: ... both file1 and file2 are tracked ... $ cat file1 >>file2 $ git add file1 file2 $ git commit This is because we avoid the expensive find-copies-harder code that makes unchanged file (in this case, file1) as a candidate for copy & paste source when annotating an existing file (file2). The third -C now allows it. However, this obviously makes the process very expensive. We've actually seen this patch before, but I dismissed it because it covers such a narrow (and arguably stupid) corner case. Signed-off-by: Junio C Hamano <junkio@cox.net>
| * blame: Notice a wholesale incorporation of an existing file.Junio C Hamano2007-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | The -C option to blame tries to find a section of a preimage file by running diff against the lines whose origin is still unknown, and excluding the different parts. The code however did not cover the case where the tail part of the section matched, which we handle for the normal non-move/copy codepath. This breakage was most visible when preimage file matches in its entirety and failed to pass blame in such a case. Signed-off-by: Junio C Hamano <junkio@cox.net>
* | blame: use .mailmap unconditionallyJunio C Hamano2007-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There really isn't any point in turning off .mailmap. The number of mailmap lookups are bounded by number of lines in the target file, and the real blame processing is much more expensive. If it turns out to be too costly, we should optimize the mailmap lookup itself, instead of avoiding the call. If the author information of commits of the project are relatively clean, .mailmap would have only small number of entries, and the overhead of looking it up will not be high. On the other hand, if the author information is really screwed up that a good .mailmap needs to be maintained to run shortlog, giving uncleaned names in blame output is not helpful at all either.
