Sun Jan 27 08:51:39 PST 2008 Duncan Coutts <duncan(a)haskell.org> * Simplify findPackageDesc code, removing old checks It used to look for and warn about Setup.description files. That's from a very very old transition which is now complete. We can just ignore any files like that now. M ./Distribution/Simple/Utils.hs -47 +17

[Hackage] #180: configure should warn if a declared licence file is missing
by Hackage 27 Jan '08

#180: configure should warn if a declared licence file is missing ---------------------+------------------------------------------------------ Reporter: duncan | Owner: Type: defect | Status: new Priority: low | Milestone: Component: Cabal | Version: 1.2.2.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.4.2 Platform: Linux | ---------------------+------------------------------------------------------ There are a few packages around which declare {{{ license-file: LICENSE }}} but then that LICENSE file actually does not exist. Currently we do not discover this until we try and install at which point we get the unhelpful error: {{{ setup: LICENCE: copyFile: does not exist (No such file or directory) }}} It would be much more helpful to users and developers alike if we warned in the configure step if the file was missing. This is partly a transitional issue, since older versions of Cabal did not install license files at all, so it never noticed. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/180> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

patch applied (cabal): PackageDescription.hs: add check for existence of license file
by Duncan Coutts 27 Jan '08

27 Jan '08

Sat Jan 26 19:10:33 PST 2008 Brent Yorgey <byorgey(a)gmail.com> * PackageDescription.hs: add check for existence of license file Added a check for the existence of the license file (if one is specified in a license-file: field) during description file sanity checking. If a license is specified but does not exist, a warning is generated. This patch resolves issue #180. M ./Distribution/PackageDescription.hs -4 +18

#217: Main modules in .hsc files are not included in sdist ----------------------------+----------------------------------------------- Reporter: gwern | Owner: Type: defect | Status: reopened Priority: normal | Milestone: Cabal-1.4 Component: Cabal library | Version: 1.2.3.0 Severity: normal | Resolution: Keywords: | Difficulty: normal Ghcversion: 6.8.2 | Platform: ----------------------------+----------------------------------------------- Comment (by duncan): Replying to [comment:7 ross(a)soi.city.ac.uk] > I think it would be most intuitive if `main-is` always named the source file containing the Main module, i.e. if > {{{ > main-is: Hslock.hsc > }}} > worked for both build and sdist. On reflection, I'm not so sure. In general when we have arbitrary pre- processors there may be a tree of files used to generate a source module/file. So it's right to name the module or ultimate file rather than one of the files used to generate it (if indeed it is generated from another file at all). So in the general case it is the only thing we can name. It's also a good deal easier in the code, it means we do not have to pass into the per-compiler code where the pre-processed .hs/.lhs file is to be found (something we do not do for exposed/other-modules). It means the per-compiler build code can just assume the file has been generated and can be found in the search path. So I'll take a look at fixing the src dist side of things, so that it finds the stuff used to generate the main .hs/.lhs and includes that into the tarball. It should be just a minor adaption on what the code does already for the other-modules. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/217#comment:10> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #164: bad error message when using configuration flags that were not defined
