The cursor is a node that remembers its parent and any information + relevant to the format (see the `Node` class), building the relevant part + of the tree lazily. + Then, for each file in `map`, move the cursor into the tree to the + corresponding folder of the file: for example, if the very first file + is "a/b/c", we start from `Node[""]`, create `Node["a"]` which points to + its parent `Node[""]`, then create `Node["a/b"]`, which points to its parent + `Node["a"]`. These nodes are kept around in a stack. + If the next file in `map` is in the same subtree ("a/b/d" or "a/b/e/f"), we + add it to the stack and keep looping with the same logic of creating the + tree nodes as needed. If however the next file in `map` is *not* in the same + subtree ("a/other", if we're still in the "a/b" folder), then we know that + the subtree we're in is complete. + + ## Writing the subtree + + We have the entire subtree in the stack, so we start writing it to disk + folder by folder. The way we write a folder is to pop the stack into a list + until the folder changes, revert this list of direct children (to satisfy + the format requirement that children be sorted).

track +the state of files in the working directory, +such as set by commands like `hg add` and `hg rm`. +It also contains some cached data that help make `hg status` faster. +The name refers both to `.hg/dirstate` on the filesystem +and the corresponding data structure in memory while a Mercurial process +is running. + +The original file format, retroactively dubbed `dirstate-v1`, +is described at https://www.mercurial-scm.org/wiki/DirState. +It is made of a flat sequence of unordered variable-size entries, +so accessing any information in it requires parsing all of it. +Similarly, saving changes requires rewriting the entire file. + +The newer `dirsate-v2` file format is designed to fix these limitations +and make `hg status` faster. + +User guide +========== + +Compatibility +------------- + +The file format is experimental and may still change. +Different versions of Mercurial may not be compatible with each other +when working on a local repository that uses this format. +When using an incompatible version with the experimental format, +anything can happen including data corruption. + +Since the dirstate is entirely local and not relevant to the wire protocol, +`dirstate-v2` does not affect compatibility with remote Mercurial versions. + +When `share-safe` is enabled, different repositories sharing the same store +can use different dirstate formats. + +Enabling `dirsate-v2` for new local repositories +------------------------------------------------ + +When creating a new local repository such as with `hg init` or `hg clone`, +the `exp-dirstate-v2` boolean in the `format` configuration section +controls whether to use this file format. +This is disabled by default as of this writing. +To enable it for a single repository, run for example:: + + $ hg init my-project --config format.exp-dirstate-v2=1 + +Checking the format of an existing local repsitory +-------------------------------------------------- + +The `debugformat` commands prints information about +which of multiple optional formats are used in the current repository, +including `dirstate-v2`:: + + $ hg debugformat + format-variant repo + fncache: yes + dirstate-v2: yes + […] + +Upgrading or downgrading an existing local repository +----------------------------------------------------- + +The `debugupgrade` command does various upgrades or downgrades +on a local repository +based on the current Mercurial version and on configuration. +The same `format.exp-dirstate-v2` configuration is used again. + +Example to upgrade:: + + $ hg debugupgrade --config format.exp-dirstate-v2=1 + +Example to downgrade to `dirstate-v1`:: + + $ hg debugupgrade --config format.exp-dirstate-v2=0 + +Both of this commands do nothing but print a list of proposed changes, +which may include changes unrelated to the dirstate. +Those other changes are controlled by their own configuration keys. +Add `--run` to a command to actually apply the proposed changes. + +Backups of `.hg/requires` and `.hg/dirstate` are created +in a `.hg/upgradebackup.*` directory. +If something goes wrong, restoring those files should undo the change. + +Note that upgrading affects compatibility with older versions of Mercurial +as noted above. +This can be relevant when a repository’s files are on a USB drive +or some other removable media, or shared over the network, etc. + +Internal filesystem representation +================================== + +Requirements file +----------------- + +The `.hg/requires` file indicates which of various optional file formats +are used by a given repository. +Mercurial aborts when seeing a requirement it does not know about, +which avoids older version accidentally messing up a respository +that uses a format that was introduced later. +For versions that do support a format, the presence or absence of +the corresponding requirement indicates whether to use that format. + +When the file contains a `exp-dirstate-v2` line, +the `dirstate-v2` format is used. +With no such line `dirstate-v1` is used. + +High level description +---------------------- + +Whereas `dirstate-v1` uses a single `.hg/disrtate` file, +in `dirstate-v2` that file is a "docket" file +that only contains some metadata +and points to separate data file named `.hg/dirstate.{ID}`, +where `{ID}` is a random identifier. + +This separation allows making data files append-only +and therefore safer to memory-map. +Creating a new data file (occasionally to clean up unused data) +can be done with a different ID +without disrupting another Mercurial process +that could still be using the previous data file. + +Both files have a format designed to reduce the need for parsing, +by using fixed-size binary components as much as possible. +For data that is not fixed-size, +references to other parts of a file can be made by storing "pseudo-pointers": +integers counted in bytes from the start of a file. +For read-only access no data structure is needed, +only a bytes buffer (possibly memory-mapped directly from the filesystem) +with specific parts read on demand. + +The data file contains "nodes" organized in a tree. +Each node represents a file or directory inside the working directory +or its parent changeset. +This tree has the same structure as the filesystem, +so a node representing a directory has child nodes representing +the files and subdirectories contained directly in that directory. + +The docket file format +---------------------- + +This is implemented in `rust/hg-core/src/dirstate_tree/on_disk.rs` +and `mercurial/dirstateutils/docket.py`. + +Components of the docket file are found at fixed offsets, +counted in bytes from the start of the file: + +* Offset 0: + The 12-bytes marker string "dirstate-v2\n" ending with a newline character. + This makes it easier to tell a dirstate-v2 file from a dirstate-v1 file, + although it is not strictly necessary + since `.hg/requires` determines which format to use. + +* Offset 12: + The changeset node ID on the first parent of the working directory, + as up to 32 binary bytes. + If a node ID is shorter (20 bytes for SHA-1), + it is start-aligned and the rest of the bytes are set to zero. + +* Offset 44: + The changeset node ID on the second parent of the working directory, + or all zeros if there isn’t one. + Also 32 binary bytes. + +* Offset 76: + Tree metadata on 44 bytes, described below. + Its separation in this documentation from the rest of the docket + reflects a detail of the current implementation. + Since tree metadata is also made of fields at fixed offsets, those could + be inlined here by adding 76 bytes to each offset. + +* Offset 120: + The used size of the data file, as a 32-bit big-endian integer. + The actual size of the data file may be larger + (if another Mercurial processis in appending to it + but has not updated the docket yet). + That extra data must be ignored. + +* Offset 124: + The length of the data file identifier, as a 8-bit integer. + +* Offset 125: + The data file identifier. + +* Any additional data is current ignored, and dropped when updating the file. + +Tree metadata in the docket file +-------------------------------- + +Tree metadata is similarly made of components at fixed offsets. +These offsets are counted in bytes from the start of tree metadata, +which is 76 bytes after the start of the docket file. + +This metadata can be thought of as the singular root of the tree +formed by nodes in the data file. + +* Offset 0: + Pseudo-pointer to the start of root nodes, + counted in bytes from the start of the data file, + as a 32-bit big-endian integer. + These nodes describe files and directories found directly + at the root of the working directory. + +* Offset 4: + Number of root nodes, as a 32-bit big-endian integer. + +* Offset 8: + Total number of nodes in the entire tree that "have a dirstate entry", + as a 32-bit big-endian integer. + Those nodes represent files that would be present at all in `dirstate-v1`. + This is typically less than the total number of nodes. + This counter is used to implement `len(dirstatemap)`. + +* Offset 12: + Number of nodes in the entire tree that have a copy source, + as a 32-bit big-endian integer. + At the next commit, these files are recorded + as having been copied or moved/renamed from that source. + (A move is recorded as a copy and separate removal of the source.) + This counter is used to implement `len(dirstatemap.copymap)`. + +* Offset 16: + An estimation of how many bytes of the data file + (within its used size) are unused, as a 32-bit big-endian integer. + When appending to an existing data file, + some existing nodes or paths can be unreachable from the new root + but they still take up space. + This counter is used to decide when to write a new data file from scratch + instead of appending to an existing one, + in order to get rid of that unreachable data + and avoid unbounded file size growth. + +* Offset 20: + These four bytes are currently ignored + and reset to zero when updating a docket file. + This is an attempt at forward compatibility: + future Mercurial versions could use this as a bit field + to indicate that a dirstate has additional data or constraints. + Finding a dirstate file with the relevant bit unset indicates that + it was written by a then-older version + which is not aware of that future change. + +* Offset 24: + Either 20 zero bytes, or a SHA-1 hash as 20 binary bytes. + When present, the hash is of ignore patterns + that were used for some previous run of the `status` algorithm. + +* (Offset 44: end of tree metadata) + +Optional hash of ignore patterns +-------------------------------- + +The implementation of `status` at `rust/hg-core/src/dirstate_tree/status.rs` +has been optimized such that its run time is dominated by calls +to `stat` for reading the filesystem metadata of a file or directory, +and to `readdir` for listing the contents of a directory. +In some cases the algorithm can skip calls to `readdir` +(saving significant time) +because the dirstate already contains enough of the relevant information +to build the correct `status` results. + +The default configuration of `hg status` is to list unknown files +but not ignored files. +In this case, it matters for the `readdir`-skipping optimization +if a given file used to be ignored but became unknown +because `.hgignore` changed. +To detect the possibility of such a change, +the tree metadata contains an optional hash of all ignore patterns. + +We define: + +* "Root" ignore files as: + + - `.hgignore` at the root of the repository if it exists + - And all files from `ui.ignore.*` config. + + This set of files is sorted by the string representation of their path. + +* The "expanded contents" of an ignore files is the byte string made + by the concatenation of its contents followed by the "expanded contents" + of other files included with `include:` or `subinclude:` directives, + in inclusion order. This definition is recursive, as included files can + themselves include more files. + +This hash is defined as the SHA-1 of the concatenation (in sorted +order) of the "expanded contents" of each "root" ignore file. +(Note that computing this does not require actually concatenating +into a single contiguous byte sequence. +Instead a SHA-1 hasher object can be created +and fed separate chunks one by one.) + +The data file format +-------------------- + +This is implemented in `rust/hg-core/src/dirstate_tree/on_disk.rs` +and `mercurial/dirstateutils/v2.py`. + +The data file contains two types of data: paths and nodes. + +Paths and nodes can be organized in any order in the file, except that sibling +nodes must be next to each other and sorted by their path. +Contiguity lets the parent refer to them all +by their count and a single pseudo-pointer, +instead of storing one pseudo-pointer per child node. +Sorting allows using binary seach to find a child node with a given name +in `O(log(n))` byte sequence comparisons. + +The current implemention writes paths and child node before a given node +for ease of figuring out the value of pseudo-pointers by the time the are to be +written, but this is not an obligation and readers must not rely on it. + +A path is stored as a byte string anywhere in the file, without delimiter. +It is refered to by one or more node by a pseudo-pointer to its start, and its +length in bytes. Since there is no delimiter, +when a path is a substring of another the same bytes could be reused, +although the implementation does not exploit this as of this writing. + +A node is stored on 43 bytes with components at fixed offsets. Paths and +child nodes relevant to a node are stored externally and referenced though +pseudo-pointers. + +All integers are stored in big-endian. All pseudo-pointers are 32-bit integers +counting bytes from the start of the data file. Path lengths and positions +are 16-bit integers, also counted in bytes. + +Node components are: + +* Offset 0: + Pseudo-pointer to the full path of this node, + from the working directory root. + +* Offset 4: + Length of the full path. + +* Offset 6: + Position of the last `/` path separator within the full path, + in bytes from the start of the full path, + or zero if there isn’t one. + The part of the full path after this position is the "base name". + Since sibling nodes have the same parent, only their base name vary + and needs to be considered when doing binary search to find a given path. + +* Offset 8: + Pseudo-pointer to the "copy source" path for this node, + or zero if there is no copy source. + +* Offset 12: + Length of the copy source path, or zero if there isn’t one. + +* Offset 14: + Pseudo-pointer to the start of child nodes. + +* Offset 18: + Number of child nodes, as a 32-bit integer. + They occupy 43 times this number of bytes + (not counting space for paths, and further descendants). + +* Offset 22: + Number as a 32-bit integer of descendant nodes in this subtree, + not including this node itself, + that "have a dirstate entry". + Those nodes represent files that would be present at all in `dirstate-v1`. + This is typically less than the total number of descendants. + This counter is used to implement `has_dir`. + +* Offset 26: + Number as a 32-bit integer of descendant nodes in this subtree, + not including this node itself, + that represent files tracked in the working directory. + (For example, `hg rm` makes a file untracked.) + This counter is used to implement `has_tracked_dir`. + +* Offset 30: + A `flags` fields that packs some boolean values as bits of a 16-bit integer. + Starting from least-significant, bit masks are:: + + WDIR_TRACKED = 1 << 0 + P1_TRACKED = 1 << 1 + P2_INFO = 1 << 2 + MODE_EXEC_PERM = 1 << 3 + MODE_IS_SYMLINK = 1 << 4 + HAS_FALLBACK_EXEC = 1 << 5 + FALLBACK_EXEC = 1 << 6 + HAS_FALLBACK_SYMLINK = 1 << 7 + FALLBACK_SYMLINK = 1 << 8 + EXPECTED_STATE_IS_MODIFIED = 1 << 9 + HAS_MODE_AND_SIZE = 1 << 10 + HAS_MTIME = 1 << 11 + MTIME_SECOND_AMBIGUOUS = 1 << 12 + DIRECTORY = 1 << 13 + ALL_UNKNOWN_RECORDED = 1 << 14 + ALL_IGNORED_RECORDED = 1 << 15 + + The meaning of each bit is described below. + + Other bits are unset. + They may be assigned meaning if the future, + with the limitation that Mercurial versions that pre-date such meaning + will always reset those bits to unset when writing nodes. + (A new node is written for any mutation in its subtree, + leaving the bytes of the old node unreachable + until the data file is rewritten entirely.) + +* Offset 32: + A `size` field described below, as a 32-bit integer. + Unlike in dirstate-v1, negative values are not used. + +* Offset 36: + The seconds component of an `mtime` field described below, + as a 32-bit integer. + Unlike in dirstate-v1, negative values are not used. + When `mtime` is used, this is number of seconds since the Unix epoch + truncated to its lower 31 bits. + +* Offset 40: + The nanoseconds component of an `mtime` field described below, + as a 32-bit integer. + When `mtime` is used, + this is the number of nanoseconds since `mtime.seconds`, + always stritctly less than one billion. + + This may be zero if more precision is not available. + (This can happen because of limitations in any of Mercurial, Python, + libc, the operating system, …) + + When comparing two mtimes and either has this component set to zero, + the sub-second precision of both should be ignored. + False positives when checking mtime equality due to clock resolution + are always possible and the status algorithm needs to deal with them, + but having too many false negatives could be harmful too. + +* (Offset 44: end of this node) + +The meaning of the boolean values packed in `flags` is: + +`WDIR_TRACKED` + Set if the working directory contains a tracked file at this node’s path. + This is typically set and unset by `hg add` and `hg rm`. + +`P1_TRACKED` + Set if the working directory’s first parent changeset + (whose node identifier is found in tree metadata) + contains a tracked file at this node’s path. + This is a cache to reduce manifest lookups. + +`P2_INFO` + Set if the file has been involved in some merge operation. + Either because it was actually merged, + or because the version in the second parent p2 version was ahead, + or because some rename moved it there. + In either case `hg status` will want it displayed as modified. + +Files that would be mentioned at all in the `dirstate-v1` file format +have a node with at least one of the above three bits set in `dirstate-v2`. +Let’s call these files "tracked anywhere", +and "untracked" the nodes with all three of these bits unset. +Untracked nodes are typically for directories: +they hold child nodes and form the tree structure. +Additional untracked nodes may also exist. +Although implementations should strive to clean up nodes +that are entirely unused, other untracked nodes may also exist. +For example, a future version of Mercurial might in some cases +add nodes for untracked files or/and ignored files in the working directory +in order to optimize `hg status` +by enabling it to skip `readdir` in more cases. + +`HAS_MODE_AND_SIZE` + Must be unset for untracked nodes. + For files tracked anywhere, if this is set: + - The `size` field is the expected file size, + in bytes truncated its lower to 31 bits. + - The expected execute permission for the file’s owner + is given by `MODE_EXEC_PERM` + - The expected file type is given by `MODE_IS_SIMLINK`: + a symbolic link if set, or a normal file if unset. + If this is unset the expected size, permission, and file type are unknown. + The `size` field is unused (set to zero). + +`HAS_MTIME` + The nodes contains a "valid" last modification time in the `mtime` field. + + + It means the `mtime` was already strictly in the past when observed, + meaning that later changes cannot happen in the same clock tick + and must cause a different modification time + (unless the system clock jumps back and we get unlucky, + which is not impossible but deemed unlikely enough). + + This means that if `std::fs::symlink_metadata` later reports + the same modification time + and ignored patterns haven’t changed, + we can assume the node to be unchanged on disk. + + The `mtime` field can then be used to skip more expensive lookup when + checking the status of "tracked" nodes. + + It can also be set for node where `DIRECTORY` is set. + See `DIRECTORY` documentation for details. + +`DIRECTORY` + When set, this entry will match a directory that exists or existed on the + file system. + + * When `HAS_MTIME` is set a directory has been seen on the file system and + `mtime` matches its last modificiation time. However, `HAS_MTIME` not being set + does not indicate the lack of directory on the file system. + + * When not tracked anywhere, this node does not represent an ignored or + unknown file on disk. + + If `HAS_MTIME` is set + and `mtime` matches the last modification time of the directory on disk, + the directory is unchanged + and we can skip calling `std::fs::read_dir` again for this directory, + and iterate child dirstate nodes instead. + (as long as `ALL_UNKNOWN_RECORDED` and `ALL_IGNORED_RECORDED` are taken + into account) + +`MODE_EXEC_PERM` + Must be unset if `HAS_MODE_AND_SIZE` is unset. + If `HAS_MODE_AND_SIZE` is set, + this indicates whether the file’s own is expected + to have execute permission. + +`MODE_IS_SYMLINK` + Must be unset if `HAS_MODE_AND_SIZE` is unset. + If `HAS_MODE_AND_SIZE` is set, + this indicates whether the file is expected to be a symlink + as opposed to a normal file. + +`EXPECTED_STATE_IS_MODIFIED` + Must be unset for untracked nodes. + For: + - a file tracked anywhere + - that has expected metadata (`HAS_MODE_AND_SIZE` and `HAS_MTIME`) + - if that metadata matches + metadata found in the working directory with `stat` + This bit indicates the status of the file. + If set, the status is modified. If unset, it is clean. + + In cases where `hg status` needs to read the contents of a file + because metadata is ambiguous, this bit lets it record the result + if the result is modified so that a future run of `hg status` + does not need to do the same again. + It is valid to never set this bit, + and consider expected metadata ambiguous if it is set. + +`ALL_UNKNOWN_RECORDED` + If set, all "unknown" children existing on disk (at the time of the last + status) have been recorded and the `mtime` associated with + `DIRECTORY` can be used for optimization even when "unknown" file + are listed. + + Note that the amount recorded "unknown" children can still be zero if None + where present. + + Also note that having this flag unset does not imply that no "unknown" + children have been recorded. Some might be present, but there is no garantee + that is will be all of them. + +`ALL_IGNORED_RECORDED` + If set, all "ignored" children existing on disk (at the time of the last + status) have been recorded and the `mtime` associated with + `DIRECTORY` can be used for optimization even when "ignored" file + are listed. + + Note that the amount recorded "ignored" children can still be zero if None + where present. + + Also note that having this flag unset does not imply that no "ignored" + children have been recorded. Some might be present, but there is no garantee + that is will be all of them. + +`HAS_FALLBACK_EXEC` + If this flag is set, the entry carries "fallback" information for the + executable bit in the `FALLBACK_EXEC` flag. + + Fallback information can be stored in the dirstate to keep track of + filesystem attribute tracked by Mercurial when the underlying file + system or operating system does not support that property, (e.g. + Windows). + +`FALLBACK_EXEC` + Should be ignored if `HAS_FALLBACK_EXEC` is unset. If set the file for this + entry should be considered executable if that information cannot be + extracted from the file system. If unset it should be considered + non-executable instead. + +`HAS_FALLBACK_SYMLINK` + If this flag is set, the entry carries "fallback" information for symbolic + link status in the `FALLBACK_SYMLINK` flag. + + Fallback information can be stored in the dirstate to keep track of + filesystem attribute tracked by Mercurial when the underlying file + system or operating system does not support that property, (e.g. + Windows). + +`FALLBACK_SYMLINK` + Should be ignored if `HAS_FALLBACK_SYMLINK` is unset. If set the file for + this entry should be considered a symlink if that information cannot be + extracted from the file system. If unset it should be considered a normal + file instead. + +`MTIME_SECOND_AMBIGUOUS` + This flag is relevant only when `HAS_FILE_MTIME` is set. When set, the + `mtime` stored in the entry is only valid for comparison with timestamps + that have nanosecond information. If available timestamp does not carries + nanosecond information, the `mtime` should be ignored and no optimisation + can be applied.
