2016-06-14repack: extend --keep-unreachable to loose objectsJeff King
If you use "repack -adk" currently, we will pack all objects that are already packed into the new pack, and then drop the old packs. However, loose unreachable objects will be left as-is. In theory these are meant to expire eventually with "git prune". But if you are using "repack -k", you probably want to keep things forever and therefore do not run "git prune" at all. Meaning those loose objects may build up over time and end up fooling any object-count heuristics (such as the one done by "gc --auto", though since git-gc does not support "repack -k", this really applies to whatever custom scripts people might have driving "repack -k"). With this patch, we instead stuff any loose unreachable objects into the pack along with the already-packed unreachable objects. This may seem wasteful, but it is really no more so than using "repack -k" in the first place. We are at a slight disadvantage, in that we have no useful ordering for the result, or names to hand to the delta code. However, this is again no worse than what "repack -k" is already doing for the packed objects. The packing of these objects doesn't matter much because they should not be accessed frequently (unless they actually _do_ become referenced, but then they would get moved to a different part of the packfile during the next repack).

2016-06-14repack: add --keep-unreachable optionJeff King
The usual way to do a full repack (and what is done by git-gc) is to run "repack -Ad --unpack-unreachable=<when>", which will loosen any unreachable objects newer than "<when>", and drop any older ones. This is a safer alternative to "repack -ad", because "<when>" becomes a grace period during which we will not drop any new objects that are about to be referenced. However, it isn't perfectly safe. It's always possible that a process is about to reference an old object. Even if that process were to take care to update the timestamp on the object, there is no atomicity with a simultaneously running "repack" process. So while unlikely, there is a small race wherein we may drop an object that is in the process of being referenced. If you do automated repacking on a large number of active repositories, you may hit it eventually, and the result is a corrupted repository. It would be nice to fix that race in the long run, but it's complicated. In the meantime, there is a much simpler strategy for automated repository maintenance: do not drop objects at all. We already have a "--keep-unreachable" option in pack-objects; we just need to plumb it through from git-repack. Note that this _isn't_ plumbed through from git-gc, so at this point it's strictly a tool for people doing their own advanced repository maintenance strategy.

2016-01-15strbuf: introduce strbuf_getline_{lf,nul}()Junio C Hamano
The strbuf_getline() interface allows a byte other than LF or NUL as the line terminator, but this is only because I wrote these codepaths anticipating that there might be a value other than NUL and LF that could be useful when I introduced line_termination long time ago. No useful caller that uses other value has emerged. By now, it is clear that the interface is overly broad without a good reason. Many codepaths have hardcoded preference to read either LF terminated or NUL terminated records from their input, and then call strbuf_getline() with LF or NUL as the third parameter. This step introduces two thin wrappers around strbuf_getline(), namely, strbuf_getline_lf() and strbuf_getline_nul(), and mechanically rewrites these call sites to call either one of them. The changes contained in this patch are: * introduction of these two functions in strbuf.[ch] * mechanical conversion of all callers to strbuf_getline() with either '\n' or '\0' as the third parameter to instead call the respective thin wrapper. After this step, output from "git grep 'strbuf_getline('" would become a lot smaller. An interim goal of this series is to make this an empty set, so that we can have strbuf_getline_crlf() take over the shorter name strbuf_getline(). Signed-off-by: Junio C Hamano <gitster@pobox.com>

As with the previous commit to git_path, assigning the result of mkpath is suspicious, since it is not clear whether we will still depend on the value after it may have been overwritten by subsequent calls.

2015-06-25introduce "preciousObjects" repository extensionJeff King
If this extension is used in a repository, then no operations should run which may drop objects from the object storage. This can be useful if you are sharing that storage with other repositories whose refs you cannot see. For instance, if you do: $ git clone -s parent child $ git -C parent config extensions.preciousObjects true $ git -C parent config core.repositoryformatversion 1 you now have additional safety when running git in the parent repository. Prunes and repacks will bail with an error, and `git gc` will skip those operations (it will continue to pack refs and do other non-object operations). Older versions of git, when run in the repository, will fail on every operation. Note that we do not set the preciousObjects extension by default when doing a "clone -s", as doing so breaks backwards compatibility. It is a decision the user should make explicitly.

If we are repacking with "-ad", we will drop any unreachable objects. Likewise, using "-Ad --unpack-unreachable=<time>" will drop any old, unreachable objects. In these cases, we want to make sure the reachability we compute with "--all" is complete. We can do this by passing GIT_REF_PARANOIA=1 in the environment to pack-objects. Note that "-Ad" is safe already, because it only loosens unreachable objects. It is up to "git prune" to avoid deleting them.

After the commit, get_pathname() may return a buffer that has just enough room for the returned string and git_path() caller should never write beyond that. Make git_path(), mkpath() and git_path_submodule() return a const buffer to make sure callers do not write in it at all.

2014-10-19repack: pack objects mentioned by the indexJeff King
When we pack all objects, we use only the objects reachable from references and reflogs. This misses any objects which are reachable from the index, but not yet referenced. By itself this isn't a big deal; the objects can remain loose until they are actually used in a commit. However, it does create a problem when we drop packed but unreachable objects. We try to optimize out the writing of objects that we will immediately prune, which means we must follow the same rules as prune in determining what is reachable. And prune uses the index for this purpose. This is rather uncommon in practice, as objects in the index would not usually have been packed in the first place. But it could happen in a sequence like: 1. You make a commit on a branch that references blob X. 2. You repack, moving X into the pack. 3. You delete the branch (and its reflog), so that X is unreferenced. 4. You "git add" blob X so that it is now referenced only by the index. 5. You repack again with git-gc. The pack-objects we invoke will see that X is neither referenced nor recent and not bother loosening it. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

When stripping a suffix like: if (ends_with(str, "foo")) buf = xmemdupz(str, strlen(str) - 3); we can instead use strip_suffix to avoid the constant 3, which must match the literal "foo" (we sometimes use strlen("foo") instead, but that means we are repeating ourselves). The example above becomes: if (strip_suffix(str, "foo", &len)) buf = xmemdupz(str, len); This also saves a strlen(), since we calculate the string length when detecting the suffix. Note that in some cases we also switch from xstrndup to xmemdupz, which saves a further strlen call. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The config option to turn on bitmaps is read all the way down in the plumbing of pack-objects. This makes it hard for other options in the porcelain of repack to make decisions based on the bitmap setting. For example, repack.packKeptObjects tries to kick in by default only when bitmaps are turned on. But it can't do so reliably because it doesn't yet know whether we are using bitmaps.

Commit ee34a2b (repack: add `repack.packKeptObjects` config var, 2014-03-03) added a flag which could duplicate kept objects, but did not mean to turn it on by default. Instead, the option is tied by default to the decision to write bitmaps, like: if (pack_kept_objects < 0) pack_kept_objects = write_bitmap; after which we expect pack_kept_objects to be a boolean 0 or 1. However, that assignment neglects that write_bitmap is _also_ a tri-state with "-1" as the default, and with neither option given, we accidentally turn the option on. This patch is the minimal fix to restore the desired behavior for the default state. Further patches will fix the more complicated cases. Note the update to t7700. It failed to turn on bitmaps, meaning we were actually confirming the wrong behavior! Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-03-03repack: add `repack.packKeptObjects` config varJeff King
The git-repack command always passes `--honor-pack-keep` to pack-objects. This has traditionally been a good thing, as we do not want to duplicate those objects in a new pack, and we are not going to delete the old pack. However, when bitmaps are in use, it is important for a full repack to include all reachable objects, even if they may be duplicated in a .keep pack. Otherwise, we cannot generate the bitmaps, as the on-disk format requires the set of objects in the pack to be fully closed. Even if the repository does not generally have .keep files, a simultaneous push could cause a race condition in which a .keep file exists at the moment of a repack. The repack may try to include those objects in one of two situations: 1. The pushed .keep pack contains objects that were already in the repository (e.g., blobs due to a revert of an old commit). 2. Receive-pack updates the refs, making the objects reachable, but before it removes the .keep file, the repack runs. In either case, we may prefer to duplicate some objects in the new, full pack, and let the next repack (after the .keep file is cleaned up) take care of removing them. This patch introduces both a command-line and config option to disable the `--honor-pack-keep` option. By default, it is triggered when pack.writeBitmaps (or `--write-bitmap-index` is turned on), but specifying it explicitly can override the behavior (e.g., in cases where you prefer .keep files to bitmaps, but only when they are present). Note that this option just disables the pack-objects behavior. We still leave packs with a .keep in place, as we do not necessarily know that we have duplicated all of their objects.

2014-02-05repack.c: rename and unlink pack file if it existsTorsten Bögershausen
When a repo was fully repacked, and is repacked again, we may run into the situation that "new" packfiles have the same name as already existing ones (traditionally packfiles have been named after the list of names of objects in them, so repacking all the objects in a single pack would have produced a packfile with the same name). The logic is to rename the existing ones into filename like "old-XXX", create the new ones and then remove the "old-" ones. When something went wrong in the middle, this sequence is rolled back by renaming the "old-" files back. The renaming into "old-" did not work as intended, because file_exists() was done on "XXX", not "pack-XXX". Also when rolling back the change, the code tried to rename "old-pack-XXX" but the saved ones are named "old-XXX", so this couldn't have worked.

2014-01-23repack: propagate pack-objects options as stringsJeff King
In the original shell version of git-repack, any options destined for pack-objects were left as strings, and passed as a whole. Since the C rewrite in commit a1bbc6c (repack: rewrite the shell script in C, 2013-09-15), we now parse these values to integers internally, then reformat the integers when passing the option to pack-objects. This has the advantage that we catch format errors earlier (i.e., when repack is invoked, rather than when pack-objects is invoked). It has three disadvantages, though: 1. Our internal data types may not be the right size. In the case of "--window-memory" and "--max-pack-size", these are "unsigned long" in pack-objects, but we can only represent a regular "int". 2. Our parsing routines might not be the same as those of pack-objects. For the two options above, pack-objects understands "100m" to mean "100 megabytes", but repack does not. 3. We have to keep a sentinel value to know whether it is worth passing the option along. In the case of "--window-memory", we currently do not pass it if the value is "0". But that is a meaningful value to pack-objects, where it overrides any configured value. We can fix all of these by simply passing the strings from the user along to pack-objects verbatim. This does not actually fix anything for "--depth" or "--window", but these are converted, too, for consistency.

2013-12-30repack: consider bitmaps when performing repacksVicent Marti
Since `pack-objects` will write a `.bitmap` file next to the `.pack` and `.idx` files, this commit teaches `git-repack` to consider the new bitmap indexes (if they exist) when performing repack operations. This implies moving old bitmap indexes out of the way if we are repacking a repository that already has them, and moving the newly generated bitmap indexes into the `objects/pack` directory, next to their corresponding packfiles. Since `git repack` is now capable of handling these `.bitmap` files, a normal `git gc` run on a repository that has `pack.writebitmaps` set to true in its config file will generate bitmap indexes as part of the garbage collection process. Alternatively, `git repack` can be called with the `-b` switch to explicitly generate bitmap indexes if you are experimenting and don't want them on all the time.

2013-12-30repack: handle optional files created by pack-objectsJeff King
We ask pack-objects to pack to a set of temporary files, and then rename them into place. Some files that pack-objects creates may be optional (like a .bitmap file), in which case we would not want to call rename(). We already call stat() and make the chmod optional if the file cannot be accessed. We could simply skip the rename step in this case, but that would be a minor regression in noticing problems with non-optional files (like the .pack and .idx files). Instead, we can now annotate extensions as optional, and skip them if they don't exist (and otherwise rely on rename() to barf).

This is slightly more verbose, but will let us annotate the extensions with further options in future commits. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-12-30repack: stop using magic number for ARRAY_SIZE(exts)Jeff King
We have a static array of extensions, but hardcode the size of the array in our loops. Let's pull out this magic number, which will make it easier to change. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-12-17cmd_repack(): remove redundant local variable "nr_packs"Michael Haggerty
Its value is the same as the number of entries in the "names" string_list, so just use "names.nr" in its place. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Acked-by: Stefan Beller <stefanbeller@googlemail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-12-05replace {pre,suf}fixcmp() with {starts,ends}_with()Christian Couder
Leaving only the function definitions and declarations so that any new topic in flight can still make use of the old functions, replace existing uses of the prefixcmp() and suffixcmp() with new API functions. The change can be recreated by mechanically applying this: $ git grep -l -e prefixcmp -e suffixcmp -- \*.c | grep -v strbuf\\.c | xargs perl -pi -e ' s|!prefixcmp\(|starts_with\(|g; s|prefixcmp\(|!starts_with\(|g; s|!suffixcmp\(|ends_with\(|g; s|suffixcmp\(|!ends_with\(|g; ' on the result of preparatory changes in this series.
