ALPM library overview & internals ================================= Here is a list of the main objects and files from the ALPM (i.e. Arch Linux Package Management) library. This document, while not exhaustive, also indicates some limitations (on purpose, or sometimes due to its poor design) of the library at the present time. There is one special file,"alpm.h", which is the public interface that should be distributed and installed on systems with the library. Only structures, data and functions declared within this file are made available to the frontend. Lots of structures are of an opaque type and their fields are only accessible in read-only mode, through some clearly defined functions. In addition to "alpm.h", the interfaces of "alpm_list.h" have also been made available to the frontend, for allowing it to manipulate the lists returned by the backend. Several structures and functions have been renamed compared to pacman 2.9 code. This was done at first for the sake of naming scheme consistency, and then primarily because of potential namespace conflicts between library and frontend spaces. Indeed, it is not possible to have two different functions with the same name declared in both spaces. To avoid such conflicts, internal function names have been prepended with "_alpm_". In a general manner, public library functions are named "alpm_<type>_<action>" (examples: alpm_trans_commit(), alpm_release(), alpm_pkg_get_name(), ...). Internal (and thus private) functions should be named "_alpm_XXX" for instance (examples: _alpm_needbackup(), _alpm_runscriplet(), ...). Functions defined and used inside a single file should be defined as "static". [Initialization] alpm_initialize() is used to initialize library internals and to create a transparent handle object. Before its call, the library can't be used. alpm_release() just does the opposite (memory used by the library, and the handle is freed). After its call, the library is no longer available. [Options] The library does not use any configuration file. It is up to the front end to configure the library as needed; the handle holds a number of configuration options instead. All of the following options have a alpm_option_get_* and alpm_option_set_* function for getting and setting the value. They cannot be set before the library is initialized. * logcb: The callback function for "log" operations. * dlcb: The callback function for download progress of each package. * fetchcb: Callback for custom download function. * totaldlcb: The callback function for overall download progress. * eventcb: Callback for transaction messages. * questioncb: Callback for selecting amongst choices. * progresscb: Callback to handle display of transaction progress. * gpgdir: Directory where GnuPG files are stored. * arch: Allowed package architecture. * checkspace: Check disk space before installing. * default_siglevel: Default signature verification level. * local_file_siglevel: Signature verification level for local file upgrades. * remote_file_siglevel: Signature verification level for remote file upgrades. * logfile: The base path to pacman's log file (Default: /var/log/pacman.log) * usesyslog: Log to syslog instead of `logfile` for file-base logging. The following options also have `alpm_option_{add,remove}_*` functions, as the values are list structures. NOTE: The add and remove functions are NOT plural, as they are in English: alpm_option_{get,set}_noupgrades -> alpm_option_{add,remove}_noupgrade. * cachedirs: Paths to pacman's download caches (Default: /var/cache/pacman/pkg) * noupgrades: Files which will never be touched by pacman (extracted as .pacnew) * noextracts: Files which will never be extracted at all (no .pacnew file) * ignorepkgs: Packages to ignore when upgrading. * ignoregrps: Groups to ignore when upgrading. The following options are read-only, having ONLY alpm_option_get_* functions: * root: The root directory for pacman to install to * dbpath: The toplevel database directory * lockfile: The file used for locking the database (Default: <dbpath>/db.lck) [Transactions] The transaction structure permits easy manipulations of several packages at a time (i.e. adding, upgrade and removal operations). A transaction can be initiated with a type (SYNC, UPGRADE or REMOVE), and some flags (NODEPS, FORCE, CASCADE, ...). Note: there can only be one type at a time: a transaction is either created to add packages to the system, or either created to remove packages. The frontend can't request for mixed operations: it has to run several transactions, one at a time, in such a case. The flags allow to tweak the library behaviour during its resolution. Note, that some options of the handle can also modify the behavior of a transaction (NOUPGRADE, IGNOREPKG, ...). Note: once a transaction has been initiated, it is not possible anymore to modify its type or its flags. One can also add some targets to a transaction (alpm_trans_addtarget()). These targets represent the list of packages to be handled. Then, a transaction needs to be prepared (alpm_trans_prepare()). It means that the various targets added, will be inspected and challenged against the set of already installed packages (dependency checking, etc...) Last, a callback is associated with each transaction. During the transaction resolution, each time a new step is started or done (i.e dependency or conflict checking, package adding or removal, ...), the callback is called, allowing the frontend to be aware of the progress of the resolution. Can be useful to implement a progress bar. [Package Cache] libalpm maintains two caches for each DB. One is a general package cache, the other is a group cache (for package groups). These caches are loaded on demand, and freed when the library is. It is important to note that, as a general rule, package structures should NOT be freed manually, as they SHOULD be part of the cache. The cache of a database is always updated by the library after an operation changing the database content (adding and/or removal of packages). Beware frontends ;) [Package] The package structure maintains all information for a package. In general, packages should never be freed from front-ends, as they should always be part of the package cache. The 'origin' data member indicates whether the package is from a file (i.e. -U operations) or from the package cache. In the case of a file, all data members available are present in the structure. Packages indicated as being from the cache have data members filled on demand. For this reason, the alpm_pkg_get_* functions will load the data from the DB as needed. [Errors] The library provides a global variable pm_errno. It aims at being to the library what errno is for C system calls. Almost all public library functions are returning an integer value: 0 indicating success, -1 indicating a failure. If -1 is returned, the variable pm_errno is set to a meaningful value Wise frontends should always care for these returned values. Note: the helper function alpm_strerror() can also be used to translate one specified error code into a more friendly sentence, and alpm_strerrorlast() does the same for the last error encountered (represented by pm_errno). [List - alpm_list_t] The alpm_list_t structure is a doubly-linked list for use with the libalpm routines. This type is provided publicly so that frontends are free to use it if they have no native list type (C++, glib, python, etc all have list types). See the proper man pages for alpm_list_t references. PACMAN frontend overview & internals ==================================== Here are some words about the frontend responsibilities. The library can operate only a small set of well defined operations and dummy operations. High level features are left to the frontend ;) For instance, during a sysupgrade, the library returns the whole list of packages to be upgraded, without any care for its content. The frontend can inspect the list and perhaps notice that "pacman" itself has to be upgraded. In such a case, the frontend can choose to perform a special action. [MAIN] (see pacman.c) Calls for alpm_initialize(), and alpm_release(). Read the configuration file, and parse command line arguments. Based on the action requested, it initiates the appropriate transactions (see pacman_upgrade(), pacman_remove(), pacman_sync() in files upgrade.c, remove.c and sync.c). [CONFIGURATION] (see conf.h) The frontend is using a configuration file, usually "/etc/pacman.conf". Some of these options are only useful for the frontend only (mainly the ones used to control the output like totaldownload, or the behavior with cleanmethod and syncfirst). The rest is used to configure the library. [UPGRADE/REMOVE/SYNC] The file pacman.c has been divided into several smaller files, namely upgrade.c, remove.c, sync.c and query.c, to hold the big parts: pacman_upgrade, pacman_remove, pacman_sync. These 3 functions have been split to ease the code reading.

Package management in git for windows?

As mentioned in issue 397:

This is intended. We do not ship pacman with Git for Windows.
If you are interested in a fully fledged package manager maintained environment you have to give the Git for Windows SDK a try.

The bash that you see in the latest git for Windows (2.5.3), which is a more recent bash than the old msysgit one, is only there to execute git commands.
It is not a full-fledged linux environment to install any third-party package.


Git for Windows (https://gitforwindows.org/ or https://git-scm.com/downloads) has Git Bash but it does not include .

is available via (Package Manager), but that is only available if you install "Git for Windows SDK" (scroll to the bottom of https://gitforwindows.org/ which provides a link to download installer for it from https://github.com/git-for-windows/build-extra/releases/latest)

The accepted answer was very helpful. They mention that was not meant to include in the default install.

So I installed "Git for Windows SDK", then in its bash prompt (SDK-64) I ran the following to install current tree v1.7.0-1 (as of this posting Aug 30, 2018):

On my system, Git for Windows SDK is installed under: , so from my Git for Windows Bash shell (which did not have tree installed), I copied it over tree.exe to its directory, e.g.

Now I can run v1.7.0 from both Git Bash shells.

To make it even easier for others and maybe myself on a future machine, I looked at where was getting the package from by running the following in my Git for Windows SDK Bash terminal:

The key thing here is that is getting from the "msys" repository (FYI: even though it says msys, it really is using msys2), so I looked at and the first mirror points to

So next time you want a package that is NOT in Git for Windows, you can download them from: http://repo.msys2.org/msys/x86_64/ (for 64-bit) or from http://repo.msys2.org/msys/i686/ (32-bit)

e.g. direct download link for tree v1.7.0-1

  • 64-bit: http://repo.msys2.org/msys/x86_64/tree-1.7.0-1-x86_64.pkg.tar.xz
  • or https://sourceforge.net/projects/msys2/files/REPOS/MSYS2/x86_64/tree-1.7.0-1-x86_64.pkg.tar.xz
  • 32-bit: http://repo.msys2.org/msys/i686/tree-1.7.0-1-i686.pkg.tar.xz
  • or https://sourceforge.net/projects/msys2/files/REPOS/MSYS2/i686/tree-1.7.0-1-i686.pkg.tar.xz

FYI: Git SCM's Window's download at https://git-scm.com/download/ pulls the latest from Git for Windows GitHub (https://github.com/git-for-windows/git from the https://github.com/git-for-windows/git/releases/ link)


I did not want to move from my already working Git for Windows installation so I improvised a bit:

  1. Install Git for Windows SDK somewhere else. You'll need more than 3 GB of free space for that.
  2. Copy to
  3. Copy and to
  4. Copy to

That's all. You can now open your Git Bash and run to install packages on your existing Git for Windows setup.

You will need write access to Git for Windows directory. Also, your now thinks it has a lot of packages installed (from SDK) but it did not stop me from using it.

Package management in git for windows?

"Git for Windows SDK" is 5.33GB compared to "Git for Windows" 691MB compared to "Portable Git" 275MB. I use the lean and mean Portable Git. At first, it seems hopeless trying to restore and use pacman in the latter two flavors of Git (msys2), because Google excluded ALL metadata files in /var/lib/pacman/local. Please read this official explanation:

https://wiki.archlinux.org/index.php/Pacman#.22Failed_to_commit_transaction_.28conflicting_files.29.22_error

Without those metadata files, you don't know the exact collection and version of the msys2 packages Google selected to build a release of those 2 flavors of Git. If you force to install or copy the current version of msys2 packages, you run the risk of version mismatch with git binaries Google built and tested.

Well, that's until I discover this file: /etc/package-versions.txt, the laundry list of matching msys2 packages and versions. Now there is a definitive source in github. Here is how I restore pacman in Portable Git:

Step 1: Run these commands to download /etc/pacman.conf and 3 packages: pacman, pacman-mirrors and msys2-keyring. These are .xz packages before msys2 switched to zstd. See my comment below.

Step 2: Unpack them at the root then restore pacman with these commands:

Step 3: The next two commands restore all matching metadata. The second command is multi-line but still safe to cut and paste (be patient):

Step 4: Now, is it too much to ask for 'make' and 'zip'?

Voilà, still just a 337MB mean little environment that can expand and upgrade!
