A Haskell library for parsing .eventlog files emitted by the GHC runtime system.
The package also includes an executable, ghc-events that can be used to display the contents of .eventlog files
TODO
Add example usage/tutorial of the new API to this readme
Known Issues
Writing event logs back to file does not work. It is hard to say how long has this been broken or how difficult will it be to fix (#14)
Changes
Change Log
0.17.0.2 - 2022-02-14
Clarify usage of IntMap EventType in ppEvent (#80)
Old parser replaced with an incremental implementation
General overhaul of the codebase
Partial Haddock coverage
The 0.5.* releases should be able to handle large event logs and logs that have been cut off abruptly, e.g. from executable runs that resulted in crashes.
This release should be mostly backwards compatible, however the “old” way of reading event logs, namely the readEventLogFromFile function is now deprecated.
NOTE: Users parsing large logs may notice that this version of the library is noticably slower than the older versions. The incremental parser is at fault here - previous versions of the libray used a “trick” that would let them essentially skip the first step of the mergesort algorithm since EventBlocks were already sorted in time order. The new parser reads the file incrementally and cannot take the advantage of this. Apologies for any inconvenience this may have caused.
