New management of dependencies:
- Even if only required or recommended deps only are requested and built, account for optional deps to build the pacakge order - build "runtime" deps after the pacakge dependening on them, but before any other package - using the "first" role in the book, implement pass1 pacakges when there are circular dependencies - Documentation has still to be written - There must be bugs, thank you for testing...

|
||||
# This is a set of (recursive) functions for manipulating a dependency #
|
||||
# tree. Everything would be "simple" without circular dependencies. We #
|
||||
# would just have to build the tree using the packages.xml file, and to #
|
||||
# provide a function for browsing it. But we need to be able to detect #
|
||||
# circular dependencies and to possibly change the tree depending on #
|
||||
# priorities. This is why we keep with each node a record of the path #
|
||||
# from the root to the node, which we call *link* and a record of the #
|
||||
# successive priorities which we call *priolink*. #
|
||||
# #
|
||||
# Layout of the tree: #
|
||||
# #
|
||||
# A node of the tree is represented by a file <nodeName>.dep. We keep all #
|
||||
# those files in the same directory. The root node file is "root.dep". #
|
||||
# Files <nodeName>.dep have the following layout: #
|
||||
# - the first line is the link: the link is an array of numbers #
|
||||
# (n1 n2 ... nN), describing the path from the root to <nodeName>: n1 #
|
||||
# is the position of the first node of the path in root.dep, n2 is the #
|
||||
# position of the second node of the path in <node1>.dep and so on. The #
|
||||
# link is not needed for normal tree operations (building a subtree or #
|
||||
# browsing the tree), but it allows to check whether a dependency is #
|
||||
# circular, and to find its parent. #
|
||||
# - the second line is an array of priorities (p1 p2 ... pN), giving the #
|
||||
# priority (1=required, 2=recommended, 3=optional) of each dependency #
|
||||
# in the link. #
|
||||
# - each subsequent line is of the form "p <depname>", where p is the #
|
||||
# priority as above, and <depname> is the name of the dependency. The #
|
||||
# position which is recorded in the link is the number of the line #
|
||||
# minus 2. #
|
||||
#-----------------------------------------------------------------------------#
|
||||
# This is a set of (recursive) functions for manipulating a dependency graph. #
|
||||
# We use algorithms and definitions from chapter 4 (mainly section 4.2) of #
|
||||
# https://algs4.cs.princeton.edu/. The graph we manipulate is the directed #
|
||||
# graph of the dependencies: nodes are packages in the BLFS book. A node A is #
|
||||
# connected to a node B if package A depends on B. A topological order (rev- #
|
||||
# erted) is exactly what we want for a build order. But a topological order #
|
||||
# only exists if the graph is acyclic. We'll therefore have to remove cycles. #
|
||||
# There are a number of other features we want to consider: #
|
||||
# - edges are weighted according to the dependency requirement: #
|
||||
# 1 for required #
|
||||
# 2 for recommended #
|
||||
# 3 for optional #
|
||||
# 4 for external #
|
||||
# We should consider only edges with weight lower or equal to that #
|
||||
# specified by the user, but see below. #
|
||||
# - we do not want to build the whole book. The user specifies a set of #
|
||||
# packages, and we have to consider only nodes reachable from this set #
|
||||
# using edges of weight not exceeding the specified weight. #
|
||||
# - when doing the topological sort, we want to consider all the edges and #
|
||||
# not only those not exceeding the specified weight: If a package A in the #
|
||||
# reachable subgraph depends optionally on another package B in the same #
|
||||
# subgraph, we want to build B before A. But this means we'll have to #
|
||||
# remove cycles for all weights. #
|
||||
# - dependencies have another qualifier: before or after. The problem: if a #
|
||||
# package A depends on B with an "after" qualifier, and a package C depends #
|
||||
# on A with a "before" qualifier, C may need B to be able to use A. So the #
|
||||
# only safe way to consider "after" qualifiers is to consider that they are #
|
||||
# "before" deps for any parent of the packages considered. #
|
||||
# We'll therefore have a 3 pass procedure. First build the set of nodes #
|
||||
# reachable from the root set. Second, remove dangling edges (those pointing #
|
||||
# to packages outside the node set), and move "after" edges to "before" edges #
|
||||
# originating from the parents. Third remove cycles and generate a #
|
||||
# topological sort. #
|
||||
# #
|
||||
# TODO: document each pass
|
||||
# Data layout: #
|
||||
# TODO: needs also to document the .tree files, and the "f" qualifier
|
||||
# #
|
||||
# A node of the tree is represented by a text file <nodeName>.dep. Each edge #
|
||||
# starting from this node is represented by a line in this file. We keep #
|
||||
# those files in the same directory. We introduce a special node named root, #
|
||||
# whose edges point to the list of nodes requested by the user. Each line #
|
||||
# contains three fields: #
|
||||
# - the weight of the edge #
|
