2013-04-17cat-file: print tags raw for "cat-file -p"Libravatar Jeff King1-71/+0
When "cat-file -p" prints commits, it shows them in their raw format, since git's format is already human-readable. For tags, however, we print the whole thing raw except for one thing: we convert the timestamp on the tagger line into a human-readable date. This dates all the way back to a0f15fa (Pretty-print tagger dates, 2006-03-01). At that time there was no other way to pretty-print a tag. These days, however, neither of those matters much. The normal way to pretty-print a tag is with "git show", which is much more flexible than "cat-file -p". Commit a0f15fa also built "verify-tag --verbose" (and subsequently "tag -v") around the "cat-file -p" output. However, that behavior was lost in commit 62e09ce (Make git tag a builtin, 2007-07-20), and we went back to printing the raw tag contents. Nobody seems to have noticed the bug since then (and it is arguably a saner behavior anyway, as it shows the actual bytes for which we verified the signature). Let's drop the tagger-date formatting for "cat-file -p". It makes us more consistent with cat-file's commit pretty-printer, and as a bonus, we can drop the hand-rolled tag parsing code in cat-file (which happened to behave inconsistently with the tag pretty-printing code elsewhere). This is a change of output format, so it's possible that some callers could considered this a regression. However, the original behavior was arguably a bug (due to the inconsistency with commits), likely nobody was relying on it (even we do not use it ourselves these days), and anyone relying on the "-p" pretty-printer should be able to expect a change in the output format (i.e., while "cat-file" is plumbing, the output format of "-p" was never guaranteed to be stable).

2013-03-29cat-file: Fix an gcc -Wuninitialized warningLibravatar Ramsay Jones1-1/+1
After commit cbfd5e1c ("drop some obsolete "x = x" compiler warning hacks", 21-03-2013) removed a gcc specific hack, older versions of gcc now issue an "'contents' might be used uninitialized" warning. In order to suppress the warning, we simply initialize the variable to NULL in it's declaration.

2013-03-21drop some obsolete "x = x" compiler warning hacksLibravatar Jeff King1-1/+1
In cases where the setting and access of a variable are protected by the same conditional flag, older versions of gcc would generate a "might be used unitialized" warning. We silence the warning by initializing the variable to itself, a hack that gcc recognizes. Modern versions of gcc are smart enough to get this right, going back to at least version 4.3.5. gcc 4.1 does get it wrong in both cases, but is sufficiently old that we probably don't need to care about it anymore.

2012-07-29diff: do not use null sha1 as a sentinel valueLibravatar Jeff King1-1/+1
The diff code represents paths using the diff_filespec struct. This struct has a sha1 to represent the sha1 of the content at that path, as well as a sha1_valid member which indicates whether its sha1 field is actually useful. If sha1_valid is not true, then the filespec represents a working tree file (e.g., for the no-index case, or for when the index is not up-to-date). The diff_filespec is only used internally, though. At the interfaces to the diff subsystem, callers feed the sha1 directly, and we create a diff_filespec from it. It's at that point that we look at the sha1 and decide whether it is valid or not; callers may pass the null sha1 as a sentinel value to indicate that it is not. We should not typically see the null sha1 coming from any other source (e.g., in the index itself, or from a tree). However, a corrupt tree might have a null sha1, which would cause "diff --patch" to accidentally diff the working tree version of a file instead of treating it as a blob. This patch extends the edges of the diff interface to accept a "sha1_valid" flag whenever we accept a sha1, and to use that flag when creating a filespec. In some cases, this means passing the flag through several layers, making the code change larger than would be desirable. One alternative would be to simply die() upon seeing corrupted trees with null sha1s. However, this fix more directly addresses the problem (while bogus sha1s in a tree are probably a bad thing, it is really the sentinel confusion sending us down the wrong code path that is what makes it devastating). And it means that git is more capable of examining and debugging these corrupted trees. For example, you can still "diff --raw" such a tree to find out when the bogus entry was introduced; you just cannot do a "--patch" diff (just as you could not with any other corrupted tree, as we do not have any content to diff).

2012-02-07drop odd return value semantics from userdiff_configLibravatar Jeff King1-7/+1
When the userdiff_config function was introduced in be58e70 (diff: unify external diff and funcname parsing code, 2008-10-05), it used a return value convention unlike any other config callback. Like other callbacks, it used "-1" to signal error. But it returned "1" to indicate that it found something, and "0" otherwise; other callbacks simply returned "0" to indicate that no error occurred. This distinction was necessary at the time, because the userdiff namespace overlapped slightly with the color configuration namespace. So "diff.color.foo" could mean "the 'foo' slot of diff coloring" or "the 'foo' component of the "color" userdiff driver". Because the color-parsing code would die on an unknown color slot, we needed the userdiff code to indicate that it had matched the variable, letting us bypass the color-parsing code entirely. Later, in 8b8e862 (ignore unknown color configuration, 2009-12-12), the color-parsing code learned to silently ignore unknown slots. This means we no longer need to protect userdiff-matched variables from reaching the color-parsing code. We can therefore change the userdiff_config calling convention to a more normal one. This drops some code from each caller, which is nice. But more importantly, it reduces the cognitive load for readers who may wonder why userdiff_config is unlike every other config callback. There's no need to add a new test confirming that this works; t4020 already contains a test that sets diff.color.external.

2010-05-31Rewrite dynamic structure initializations to runtime assignmentLibravatar Gary V. Vaughan1-1/+3
Unfortunately, there are still plenty of production systems with vendor compilers that choke unless all compound declarations can be determined statically at compile time, for example hpux10.20 (I can provide a comprehensive list of our supported platforms that exhibit this problem if necessary). This patch simply breaks apart any compound declarations with dynamic initialisation expressions, and moves the initialisation until after the last declaration in the same block, in all the places necessary to have the offending compilers accept the code.

NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
