| 06:31 | Started to adapt the integrity module. Renamed Check to CheckRev, and added analoguous commands for Tags and Branches. Added placeholders for the new integrity commands, updated main changeset integrity command. ... (check-in: 7c28fe1312 user: aku tags: trunk) | |
| 06:23 | Updated the code printing the changeset statistics to know about change to the changeset types. ... (check-in: 8e3012423b user: aku tags: trunk) | |
| 06:21 | Brought knowledge of the new types to the state definition, changed the creation of the initial changesets to use tags and branches. ... (check-in: 215d2f1ad9 user: aku tags: trunk) | |
| 06:10 | Integrate the new singletons with the main class, route the relevant places to them. ... (check-in: c74fe3de3f user: aku tags: trunk) | |
| 05:58 | This commit starts a series of incremental changes not quite completely overhauling the handling of changesets, i.e. of project-level revisions. Actually this series of changes already started with [8ce7ffff21] as the bug it fixes was found when the first parts of the overhaul tripped the new integrity conditions for the modified changesets. Background: In the last few days I repeatedly ran against the wall of an assertion in pass 9, last of the cycle breakers, with the revision changesets coming in out of order when the symbols were added to the dependency graph. While walking to the office, and later re-reading the relevant parts of cvs2svn again I had several insights. Trigger was the realization that giving the tag changesets successor dependencies was wrong. Tags describe a state, they have no successors. This caused the re-read, and I recognized that my handling of the symbol changesets was completely wrong, that with using revisions as their data. It should have been the tags and branches. From there their actual dependencies (versus my reuse of revision dependencies) fell out naturally. I have decided to commit my rewrite of the internals incrementally to make it easier to follow them, despite leaving the sourcebase in an unusable state during the series. One big commit would be much more difficult to understand. The... (check-in: 27b15b7095 user: aku tags: trunk) | |

| 08:35 | Bugfix in FilterSym pass. Grafting branches operated on the tags table :( ... (check-in: 8ce7ffff21 user: aku tags: trunk) | |
| 05:39 | Added convenience method for assertions and used it in place of the existing if/trouble internal constructions. Changed API of 'log write' so that we can defer substituation of the message to when the write actually happen, and converted all places which would be hit by double-substitution. The remaining 'log write' calls will be converted incrementally. ... (check-in: 47d52d1efd user: aku tags: trunk) | |

| 09:07 | Modified to break all backward symbols, not only branches, removed the other custom circle breaking code, should not be needed any longer (See comments for proof). ... (check-in: 6b520e7d97 user: aku tags: trunk) | |
| 09:05 | Bugfix: Sort pending nodes fully deterministic, and moved to separate helper command. Tweaked log output. ... (check-in: 3e18606b5c user: aku tags: trunk) | |
| 09:04 | Updated to extended changeset string, and added tabular formatting. Further tweaked output, putting timestamp adjust messages on the same line as the changeset itself. ... (check-in: 1c39e57637 user: aku tags: trunk) | |
| 09:03 | Changesets, extended human readable representation, and tweaking of log output. ... (check-in: 911d56a8c8 user: aku tags: trunk) | |
| 08:59 | Bugfix in the generation of the initial symbol changesets. Keep entries apart per line-of-development. ... (check-in: 2e07cd7164 user: aku tags: trunk) | |
| 05:08 | Bugfixes when generating revision changesets. (1) The dependencies for a revision are a list, not single. (2) Use pseudo-dependencies to separate revisions of the same file from each other if they have no direct dependencies in the state. ... (check-in: 678765068d user: aku tags: trunk) | |
| 04:26 | Continued work on the integrity checks for changesets. Moved callers out of transactions. Two checks are already tripping on bad changesets made by InitCSets (pass 5). ... (check-in: 8c6488ded2 user: aku tags: trunk) | |
| 02:37 | Outline for more integrity checks, focusing on the changesets. ... (check-in: bf83201c7f user: aku tags: trunk) | |

| 07:37 | Fixed log output for pass 10, and added missing command. ... (check-in: 63052cb60a user: aku tags: trunk) | |
| 07:35 | Extended cycle breaker with debug facility allowing the user to watch the neighbourhood of specific changesets during the traversal. Extended label information, highlighting of the nodes of interest. Tweaked log output a bit. ... (check-in: 97b4405ecf user: aku tags: trunk) | |
| 07:32 | State log output, moved to slightly higher verbosity level to allow them to be suppressed. ... (check-in: 00e041dd22 user: aku tags: trunk) | |
| 07:31 | Dot export extended, allow graph to define label color for highlighting. ... (check-in: eb43120ac1 user: aku tags: trunk) | |

| 03:00 | Moved the parts taken over by the top. sort passes out the breaker passes, and renumbered them (comments). ... (check-in: b6b7ff79cc user: aku tags: trunk) | |
| 02:59 | Investigation of changeset order differences between running passes 1 to 6 and pass 6 alone show why the topological sort passes are separate in cvs2svn. The breaking of cycles can change the order of things due to different timeranges and dependencies of the broken changesets. Created two new passes for the sorting. The break passes 7 and 8 are now passes 8 and 9, and the new sort passes are 7 and 10. ... (check-in: 66c85b4db4 user: aku tags: trunk) | |
| 02:54 | Tweaked log output of filtering pass a bit. ... (check-in: b41127b9d8 user: aku tags: trunk) | |
| 02:53 | Tweaked human readable representation of changesets to include their type. ... (check-in: 0868adf92a user: aku tags: trunk) | |
| 02:52 | Bugfix in pass manager, handling of open-ended pass specifications. ... (check-in: 9668b16455 user: aku tags: trunk) | |
| 02:51 | Tweaks of the log output, and reworked internals to expose not only breaking of cycles, but of paths as well. ... (check-in: 54e9b0a143 user: aku tags: trunk) | |

| 05:31 | Created convenience methods to create the human readable repesentation of a changeset and lists of such, and made liberal use of them. ... (check-in: 87cf609021 user: aku tags: trunk) | |
| 04:40 | Bugfix in changeset class. Documented and fixed the SQL statements pulling the successor and predecessor information out of the state. It mishandled the Trunk <-> NTDB transitions. ... (check-in: 184c56327e user: aku tags: trunk) | |
| 04:34 | Bugfix in changeset class. Forgot to update the map from revisions to containing changesets when breaking the internal dependencies of the initial changesets. This affected only the first fragment as all the revisions put into separate fragments where still pointing to the original changeset. This lead to bogus links at the level of changesets, the changeset was seemingly still referencing itself. ... (check-in: 17ec2d682c user: aku tags: trunk) | |
| 04:29 | Bugfix in the changeset class. The index from revisions to containing changesets is not 1:1, but 1:n. While only one revision changeset is possible there can also be zero or more symbol changesets. ... (check-in: 8c9030e3e8 user: aku tags: trunk) | |
| 04:19 | Tweaked log output a bit. Bugfixes: Forgot to propagate the border information into SplitRevisions, and a varname typo. ... (check-in: 6d63634309 user: aku tags: trunk) | |
| 04:15 | Added a number of assertions and must-not-happens with associated log output. Plus some small tweaks, and notes. ... (check-in: eabaea870a user: aku tags: trunk) | |

| 05:43 | Modified cycle breaker API. Hook for processed nodes now takes the graph as new first argument. Extended API, exposed method for dumping the current state of the graph, including ability to dump a sub graph. ... (check-in: 5f5620fbd2 user: aku tags: trunk) | |
| 05:41 | Extended the dot graph exporter to allow the export of a subgraph specified through a set of nodes. Default is the export of the whole graph, as before. ... (check-in: 86f3319041 user: aku tags: trunk) | |
| 05:38 | Added two more debugging helper applications. One to extract and show a file revision tree, the other to display a dot file generated by the importer during cycle breaking passes. ... (check-in: 64d0019e0f user: aku tags: trunk) | |

| 07:24 | Added two helper applications which peek into a conversion state and generate graphs from it. Both helpers look at the tree of symbols and show it in toto (symbol tree), or restrict themselves to the branches, aka lines of development (lodtree). ... (check-in: b8c3542172 user: aku tags: trunk) | |
| 07:22 | Reworked the dot export internals a bit to be more general regarding labeling and attribute writing. Updated the cycle breaker to define proper labels. ... (check-in: f284847134 user: aku tags: trunk) | |
| 07:21 | Tweaked the log output for the statistics a bit. ... (check-in: 2630e50610 user: aku tags: trunk) | |
| 06:03 | Fixed the calculation of possible parents for a detached NTDB. Has to be trunk. The symbols were skipped before, causing them to have no parents at all later on, forcing an abort after CollateSymbols. Added some high verbosity log commands for debugging of this area. ... (check-in: 930ec162ce user: aku tags: trunk) | |
| 04:56 | Fixed bug in the initialization of mybranchcode for changesets. ... (check-in: 47e271a448 user: aku tags: trunk) | |
| 04:21 | Continued work on pass 8. Completed the handling of backward branches, file level analysis and splitting them. Extended changesets with the necessary methods to the predecessor data and proper per-revision maps. ... (check-in: e50f9ed55e user: aku tags: trunk) | |
| 03:47 | Continued work on pass 8. Renamed 'retrograde' to 'Backward Branch', should be easier to understand, and completed the predicate testing if a branch changeset is backward or not. ... (check-in: 4f1b60dd16 user: aku tags: trunk) | |
