#8886: sync-all: END actions result in confusing error message -------------------------------------+------------------------------------- Reporter: fw | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Build System | Version: 7.6.3 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: Building GHC Difficulty: Easy (less than 1 | failed hour) | Test Case: Blocked By: | Blocking: Related Tickets: | -------------------------------------+------------------------------------- The instructions at [wiki:Newcomers] were slightly outdated, and result in a rather confusing error message: {{{ $ ./sync-all --testsuite get Unrecognised flag: --testsuite at ./sync-all line 872. == Checking for old haddock repo == Checking for old binary repo == Checking for old mtl repo == Checking for old Cabal repo == Checking for old time from tarball ============================ ATTENTION! You have an old time package in your GHC tree! Please remove it (e.g. "rm -r libraries/time"), and then run "./sync-all get" to get the new repository. ============================ == Checking for obsolete Git repo URL $ }}} The patch suppresses the misleading error message. I've already removed the `--testsuite` flag from the wiki page. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8886> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

The Lexer calls prevChar when a regular expression starts with '^' (which is a shorthand for '\n^'). It would never match on the first line, since instead of '\n', prevChar would still return '\xfeff'.

#4012: Compilation results are not deterministic -------------------------------------+------------------------------------- Reporter: kili | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.10.1 Component: Compiler | Version: 6.12.2 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Difficult (2-5 Type of failure: Other | days) Test Case: | Blocked By: Blocking: | Related Tickets: Differential Revisions: | -------------------------------------+------------------------------------- Comment (by nh2): Another setback for this ticket is that parallel builds, e.g. `ghc -j4`, make builds non-deterministic. The generated closure names (`r4WO_closure...`, `r5BF_closure...`) vary with `-j` but don't without. Does anybody have an idea on how we could make sure that they are not "as shared", so that the names generated do not depend on the concurrency of the build? -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/4012#comment:54> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

Currently Peter's source notes patches are in review: https://phabricator.haskell.org/D169 Once those are merged, Peter can submit the DWARF emitting patches for review. Once also that is merged, I can submit my patches for stack traces on top of all that. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/3693#comment:72> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
