* Merge branch 'rs/logical-vs-binary-or'Junio C Hamano2013-06-203-6/+6
|\ | | | | | | | | | | | | Code cleanup. * rs/logical-vs-binary-or: use logical OR (||) instead of binary OR (|) in logical context
| * use logical OR (||) instead of binary OR (|) in logical contextRené Scharfe2013-06-133-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The compiler can short-circuit the evaluation of conditions strung together with logical OR operators instead of computing the resulting bitmask with binary ORs. More importantly, this patch makes the intent of the changed code clearer, because the logical context (as opposed to binary context) becomes immediately obvious. While we're at it, simplify the check for patch->is_rename in builtin/apply.c a bit; it can only be 0 or 1, so we don't need a comparison operator.

| |\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A git daemon that starts as "root" and then drops privilege often leaves $HOME set to that of the root user, which is unreadable by the daemon process, which was diagnosed as a configuration error. Make per-user configuration files that are inaccessible due to EACCES as though these files do not exist to avoid this issue, as the tightening which was originally meant as an additional security has annoyed enough sysadmins. * jn/config-ignore-inaccessible: config: allow inaccessible configuration under $HOME

Many tutorials tell the users to set color.ui=auto as a very first step, which tend to indicate that color.ui=none is not the recommanded value, hence should not be the default. These tutorials would benefit from skipping this step and starting the real Git manipulations earlier. Other beginners do not know about color.ui=auto, and may not discover it by themselves, hence live with black&white outputs while they may have preferred colors. A few people (e.g. color-blind) prefer having no colors, but they can easily set color.ui=never for this (and googling "disable colors in git" already tells them how to do so), but this needs not occupy space in beginner-oriented documentations. A transition period with Git emitting a warning when color.ui is unset would be possible, but the discomfort of having the warning seems superior to the benefit: users may be surprised by the change, but not harmed by it. The default value is changed, and the documentation is reworded to mention "color.ui=false" first, since the primary use of color.ui after this change is to disable colors, not to enable it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The meaning of get_colorbool_found and get_diff_color_found is "the config value if found, and -1 otherwise", but get_color_ui_found had a slightly different meaning, as it has the value 0 (which corresponds to the default value from the user point of view) when color.ui is unset. Make get_color_ui_found default to -1, and make it explicit that 0 is the default value when nothing else is found.

There is a problem unique to push.default = current: # on branch push-current-head $ git push # on another terminal $ git checkout master # return to the first terminal # the push tried to push master! This happens because the 'git checkout' on the second terminal races with the 'git push' on the first terminal. Although this patch does not solve the core problem (there is still no guarantee that 'git push' on the first terminal will resolve HEAD before 'git checkout' changes HEAD on the second), it works in practice.

This is expensive on large repositories. This patch attempts to mitigate the impact in this special case. In the "good" clone case, we only have one pack. If all of the following are met, we can be sure that all objects reachable from the new refs exist, which is the intention of running "rev-list ...": - all refs point to an object in the pack - there are no dangling pointers in any object in the pack - no objects in the pack point to objects outside the pack The second and third checks can be done with the help of index-pack as a slight variation of --strict check (which introduces a new condition for the shortcut: pack transfer must be used and the number of objects large enough to call index-pack). The first is checked in check_everything_connected after we get an "ok" from index-pack. "index-pack + new checks" is still faster than the current "index-pack + rev-list", which is the whole point of this patch. If any of the conditions fail, we fall back to the good old but expensive "rev-list ..". In that case it's even more expensive because we have to pay for the new checks in index-pack. But that should only happen when the other side is either buggy or malicious.

This shortcut does not apply to unpack-objects code path either because the number of objects must be small in order to trigger that code path.

The algorithm is built around the struct range_set, which encodes a series of line ranges as intervals [a,b). This is used in two contexts: * A set of lines we are tracking (which will change as we dig through history). * To encode diffs, as pairs of ranges. The main routine is range_set_map_across_diff(). It processes the diff between a commit C and some parent P. It determines which diff hunks are relevant to the ranges tracked in C, and computes the new ranges for P. The algorithm is then simply to process history in topological order from newest to oldest, computing ranges and (partial) diffs. At branch points, we need to merge the ranges we are watching. We will find that many commits do not affect the chosen ranges, and mark them TREESAME (in addition to those already filtered by pathspec limiting). Another pass of history simplification then gets rid of such commits. This is wired as an extra filtering pass in the log machinery. This currently only reduces code duplication, but should allow for other simplifications and options to be used. Finally, we hook a diff printer into the output chain. Ideally we would wire directly into the diff logic, to optionally use features like word diff. However, that will require some major reworking of the diff chain, so we completely replace the output with our own diff for now. As this was a GSoC project, and has quite some history by now, many people have helped.

Refactor the argument parsing of the range arguments from builtin/blame.c to the (new) file that will hold the 'git log -L' logic. To accommodate different data structures in blame and log -L, the file contents are abstracted away; parse_range_arg takes a callback that it uses to get the contents of a line of the (notional) file. The new test is for a case that made me pause during debugging: the 'blame -L with invalid end' test was the only one that noticed an outright failure to parse the end *at all*. So make a more explicit test for that. Signed-off-by: Bo Yang <struggleyb.nku@gmail.com> Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>

However, if there is a configured non-pattern refspec that does not match any of the refspecs given on the command line then a fatal error occurs. Fix this by setting the "missing_ok" flag when calling get_fetch_map.

However, when we run "git fetch origin master" (or "git pull origin master"), we do not look at the configured refspecs at all, and just update FETCH_HEAD. We miss an opportunity to update "refs/remotes/origin/master" (or whatever the user has configured). Some users find this confusing, because they would want to do further comparisons against the old state of the remote master, like: $ git pull origin master $ git log HEAD...origin/master In the currnet code, they are comparing against whatever commit happened to be in origin/master from the last time they did a complete "git fetch". This patch will update a ref from the RHS of a configured refspec whenever we happen to be fetching its LHS. That makes the case above work. The downside is that any users who really care about whether and when their tracking branches are updated may be surprised.

It would be useful to turn this boolean into a tri-state, with the third state meaning "do not bother writing it out to FETCH_HEAD at all". That would let us add extra refs to the set of refs to be stored (e.g., to store copies of things we fetched) without impacting FETCH_HEAD. This patch turns it into an enum that covers the tri-state case, and hopefully makes the code more explicit and easier to read.
