* Mechanical conversion to use prefixcmp()Junio C Hamano2007-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This mechanically converts strncmp() to use prefixcmp(), but only when the parameters match specific patterns, so that they can be verified easily. Leftover from this will be fixed in a separate step, including idiotic conversions like if (!strncmp("foo", arg, 3)) => if (!(-prefixcmp(arg, "foo"))) This was done by using this script in px.perl #!/usr/bin/perl -i.bak -p if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) { s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|; } if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) { s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|; } and running: $ git grep -l strncmp -- '*.c' | xargs perl px.perl Signed-off-by: Junio C Hamano <junkio@cox.net>

* for-each-reflog: fix case for empty log directoryJunio C Hamano2007-02-07
| | | | | | | | | | | | | When we remove the last reflog in a directory, opendir() would succeed and we would iterate over its dirents, expecting retval to be initialized to zero and setting it to non-zero only upon seeing an error. If the directory is empty, oops!, we do not have anybody that touches retval. The problem is because we initialize retval to errno even on success from opendir(), which would leave the errno unmolested. Signed-off-by: Junio C Hamano <junkio@cox.net>

| * lock_any_ref_for_update(): do not accept malformatted refs.Junio C Hamano2007-01-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to use lock_any_ref_for_update() because the command needs to also update HEAD (which is not under refs/, so lock_ref_sha1() cannot be used). The function however did not check for refs with illegal characters in them. Use check_ref_format() to catch malformed refs. For this check, we specifically do not want to say having less than two levels in the name is illegal to allow HEAD (and perhaps other special refs in the future).

* | scan reflogs independently from refsNicolas Pitre2007-02-03

* | create_symref(): do not assume pathname from git_path() persists long enoughJunio C Hamano2007-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | Being lazy to rely on the cycling N buffers mkpath() and friends return is nice in general, but it makes it too easy to introduce new bugs that are "mysterious". Introduction of read_ref() in create_symref() after calling git_path() to get the git_HEAD value (i.e. the path to create a new symref at) consumed more than the available buffers and broke a later call to mkpath() that derives lockpath from it.

* Allow non-developer to clone, checkout and fetch more easily.Junio C Hamano2007-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code that uses committer_info() in reflog can barf and die whenever it is asked to update a ref. And I do not think calling ignore_missing_committer_name() upfront like recent receive-pack did in the aplication is a reasonable workaround. What the patch does. - git_committer_info() takes one parameter. It used to be "if this is true, then die() if the name is not available due to bad GECOS, otherwise issue a warning once but leave the name empty". The reason was because we wanted to prevent bad commits from being made by git-commit-tree (and its callers). The value 0 is only used by "git var -l". Now it takes -1, 0 or 1. When set to -1, it does not complain but uses the pw->pw_name when name is not available. Existing 0 and 1 values mean the same thing as they used to mean before. 0 means issue warnings and leave it empty, 1 means barf and die. - ignore_missing_committer_name() and its existing caller (receive-pack, to set the reflog) have been removed. - git-format-patch, to come up with the phoney message ID when asked to thread, now passes -1 to git_committer_info(). This codepath uses only the e-mail part, ignoring the name. It used to barf and die. The other call in the same program when asked to add signed-off-by line based on committer identity still passes 1 to make sure it barfs instead of adding a bogus s-o-b line. - log_ref_write in refs.c, to come up with the name to record who initiated the ref update in the reflog, passes -1. It used to barf and die. The last change means that git-update-ref, git-branch, and commit walker backends can now be used in a repository with reflog by somebody who does not have the user identity required to make a commit. They all used to barf and die. I've run tests and all of them seem to pass, and also tried "git clone" as a user whose GECOS is empty -- git clone works again now (it was broken when reflog was enabled by default). But this definitely needs extra sets of eyeballs. Signed-off-by: Junio C Hamano <junkio@cox.net>

I first saved them with "format-patch -4", and then did a reset at @{8}. At @{7}, I applied one of them with "am", and then used "git-apply" on the other one, and amended the commit at @{6} (so @{6} and @{7} has the same parent). I did not like the log message, so I amended again at @{5}. Then I cherry-picked @{9}~2 to create @{3} (the log message shows that it needs to learn to set GIT_REFLOG_ACTION -- it uses "git-commit" and the log entry is attributed for it). Another cherry-pick built @{2} out of @{9}, but what I wanted to do was to squash these two into one, so I did a "reset HEAD^" at @{1} and then made the final commit by amending what was at the top.

In order to allow the repository owner override the heuristic implemented in is_bare_git_dir() if/when it misidentifies a particular repository, it would make sense to introduce a new configuration variable "[core] bare = true/false", and make is_bare_git_dir() notice it. The scripts would do a 'repo-config --bool --get core.bare' and iff the command fails (i.e. there is no such variable in the configuration file), it would use the heuristic implemented at the script level [*1*]. However, setup_git_env() which is called a lot earlier than we even read from the repository configuration currently makes a call to is_bare_git_dir(), in order to change the default setting for log_all_ref_updates. It somehow feels that this is a hack. By the way, [*1*] is another thing I hate about the current config mechanism. "git-repo-config --get" does not know what the possible configuration variables are, let alone what the default values for them are. It allows us not to maintain a centralized configuration table, which makes it easy to introduce ad-hoc variables and gives a warm fuzzy feeling of being modular, but my feeling is that it is turning out to be a rather high price to pay for scripts.

We are replacing all calls to mmap() with xmmap() and moving all MAP_FAILED checking into that single location. If a mmap call fails we try to release enough least-recently-used pack windows to possibly succeed, then retry the mmap() attempt.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was stupid to link the same element twice to lock_file_list and end up in a loop, so we certainly need a fix. But it is not like we are taking a lock on multiple files in this case. It is just that we leave the linked element on the list even after commit_lock_file() successfully removes the cruft. We cannot remove the list element in commit_lock_file(); if we are interrupted in the middle of list manipulation, the call to remove_lock_file_on_signal() will happen with a broken list structure pointed by lock_file_list, which would cause the cruft to remain, so not removing the list element is the right thing to do. Instead we should be reusing the element already on the list. There is already a code for that in lock_file() function in lockfile.c. The code checks lk->next and the element is linked only when it is not already on the list -- which is incorrect for the last element on the list (which has NULL in its next field), but if you read the check as "is this element already on the list?" it actually makes sense. We do not want to link it on the list again, nor we would want to set up signal/atexit over and over. Signed-off-by: Junio C Hamano <junkio@cox.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the previous implementation which failed to optimize repositories with tons of lightweight tags. The updated packed-refs format begins with "# packed-refs with:" line that lists the kind of extended data the file records. Currently, there is only one such extension defined, "peeled". This stores the "peeled tag" on a line that immediately follows a line for a tag object itself in the format "^<sha-1>". The header line itself and any extended data are ignored by older implementation, so packed-refs file generated with this version can still be used by older git. packed-refs made by older git can of course be used with this version.

* do_for_each_ref: perform the same sanity check for leftovers.Junio C Hamano2006-11-19
| | | | | | | | | | | | | | | An earlier commit b37a562a added a check to see if the ref points at a valid object (as a part of 'negative ref' support which we currently do not use), but did so only while iterating over both packed and loose refs, and forgot to apply the same check while iterating over the remaining ones. We might want to replace the "if null then omit it" check with "eh --- what business does a 0{40} value have here?" complaint later since we currently do not use negative refs, but that is a separate issue.

| * ref-log: allow ref@{count} syntax.Junio C Hamano2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | Often I find myself wanting to say 'tip of "next" before I merged the last three topics'. Now I can say that with: git log next@{3}..next Since small integers alone are invalid input strings to approxidate, there is no fear of confusion. Signed-off-by: Junio C Hamano <junkio@cox.net>
* | ref-log: fix D/F conflict coming from deleted refs.Junio C Hamano2006-10-19
| | | | | | | | | | | | | | | | | | | | After deleting a branch l/k, you should be able to create a branch l. Earlier we added remove_empty_directories() on the ref creation side to remove leftover .git/refs/l directory but we also need a matching code to remove .git/logs/refs/l directory.

|/ | | | | | | | | | | It used to mean "create log file for any ref that is updated", but now it creates new log files only for branch heads. The old behaviour made this configuration less useful than otherwise it would be; automatically creating log file for tags is almost always not useful. Signed-off-by: Junio C Hamano <junkio@cox.net>
