I'm encountering problems when making lazy-loadable databases of the output from 'parse_Rd'. The lazy-load database is of seemingly limitless size when I try to reload it... Admittedly I am using functions that I'm not really supposed to use, which is why this isn't a bug report, but there does seem to be something strange going on; my code is very similar to code that lives inside 'tools:::.install_package_Rd_objects'. The problems occur with just-released R2.10.0 on Windows.
The examples below use files which can be found at ftp://ftp.csiro.au/MarkBravington, but you'll obviously need to modify the paths. The file "scrunge.Rd" is just "Rdiff.Rd" from the 'tools' package. The file "fakepack.7z" should unzip to create a fake package with a DESCRIPTION file and a "man" directory that contains two Rd files. Transcript of first example: eglist <- list( scrunge=tools:::prepare_Rd( 'd:/temp/scrunge.Rd', defines=.Platform$OS.type, stages='install', warningCalls=FALSE)) tools:::makeLazyLoadDB( eglist, 'd:/temp/ll', compress=FALSE) tools:::fetchRdDB( 'd:/temp/ll') # Error: cannot allocate vector of size 1.4 Gb The second example triggers an error with 'tools:::.install_package_Rd_objects' itself. It doesn't happen the first time, but frequently does after the Rd files have been changed. Transcript: # Make sure d:/temp/help/ is empty, then test> tools:::.install_package_Rd_objects( 'd:/temp/fakepack', 'd:/temp') test> tools:::fetchRdDB( 'd:/temp/help/temp') # All good. Next, I *removed* one of the two Rd files in "d:/temp/fakepack/man", ... # ...deleted "d:/temp/help/temp*", and tried again test> tools:::.install_package_Rd_objects( 'd:/temp/fakepack', 'd:/temp') test> tools:::fetchRdDB( 'd:/temp/help/temp') Warning: Reached total allocation of 1535Mb: see help(memory.size) Warning: Reached total allocation of 1535Mb: see help(memory.size) Warning: Reached total allocation of 1535Mb: see help(memory.size) Warning: Reached total allocation of 1535Mb: see help(memory.size) Error: cannot allocate vector of size 1.9 Gb # Or on other occasions I get Error: internal error -3 in R_decompress1 Mark Bravington CSIRO CMIS Hobart Australia --please do not edit the information below-- Version: platform = i386-pc-mingw32 arch = i386 os = mingw32 system = i386, mingw32 status = major = 2 minor = 10.0 year = 2009 month = 10 day = 26 svn rev = 50208 language = R version.string = R version 2.10.0 (2009-10-26) Windows XP (build 2600) Service Pack 2 Locale: LC_COLLATE=English_Australia.1252;LC_CTYPE=English_Australia.1252;LC_MONETARY=English_Australia.1252;LC_NUMERIC=C;LC_TIME=English_Australia.1252 Search Path: .GlobalEnv, ROOT, package:grDevices, package:ad, package:chstuff, package:handy2, package:tweedie, package:statmod, package:handy, package:debug, package:mvbutils, mvb.session.info, package:tools, package:tcltk, package:stats, package:graphics, package:utils, package:methods, Autoloads, package:base ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
