This patch syncs our upstream copy of readline from version 6.2 to the latest version, 7.0 alpha (released July 10 2015). I essentially copied what was done the last time readline was synced, when Jan updated to readline 6.2 in 2011: http://sourceware.org/ml/gdb-patches/2011-05/msg00003.html Procedure: 1. I extracted the readline-7.0-alpha tarball on top of readline/. 2. I deleted all the new files under doc/ that were deliberately omitted before. 3. I regenerated readline/configure and readline/examples/rlfe/configure using autoconf 2.64. No other configure files need regenerating. 4. I updated the function gdb_printable_part in completer.c with a trivial change made to the readline function it is based off of, printable_part in readline/complete.c. There is more work to be done in completer.c to sync it with readline/complete.c, but it is non-trivial and should probably be done separately anyway. Local patches that had to be reapplied: None. readline 7.0 alpha contains all of our local readline patches. New files in readline/: colors.{c,h} examples/{hist_erasedups,hist_purgecmd,rl-callbacktest,rlbasic}.c parse-colors.{c,h} readline.pc.in configure.ac Deleted files in readline/: configure.in Regressions: After the sync there is one testsuite regression, the test "signal SIGINT" in gdb.gdb/selftest.exp which now FAILs. Previously, the readline 6.2 SIGINT handler would temporarily reinstall the underlying application's SIGINT handler and immediately re-raise SIGINT so that the orginal handler gets invoked. But now (since readline 6.3) its SIGINT handler does not re-raise SIGINT or directly invoke the original handler; it now sets a flag marking that SIGINT was raised, and waits until readline explicitly has control to call the application's SIGINT handler. Anyway, because SIGINT is no longer re-raised from within readline's SIGINT handler, doing "signal SIGINT" with a stopped inferior gdb process will no longer resume and then immediately stop the process (since there is no 2nd SIGINT to immediately catch). Instead, the inferior gdb process will now just print "Quit" and continue to run. So with this commit, this particular test case is adjusted to reflect this change in behavior (we now have to send a 2nd SIGINT manually to stop it). Aside from this one testsuite regression, I personally noticed no regression in user-visible behavior. Though I only tested on x86_64 and on i686 Debian Stretch. Getting this kind of change in at the start of the GDB 7.11 development cycle will allow us to get a lot of passive testing from developers and from bleeding-edge users. readline/ChangeLog.gdb: Import readline 7.0 alpha * configure: Regenerate. * examples/rlfe/configure: Regenerate. gdb/ChangeLog: * completer.c (gdb_printable_part): Sync with readline function it is based off of. gdb/testsuite/ChangeLog: * gdb.gdb/selftest.exp (test_with_self): Update test to now expect the GDB inferior to no longer immediately stop after being resumed with "signal SIGINT".

Usage: $program [OPTION]... FILE...
|
||
or: texi2pdf [OPTION]... FILE...
|
||
or: pdftexi2dvi [OPTION]... FILE...
|
||
|
||
Run each Texinfo or (La)TeX FILE through TeX in turn until all
|
||
cross-references are resolved, building all indices. The directory
|
||
containing each FILE is searched for included files. The suffix of FILE
|
||
is used to determine its language ((La)TeX or Texinfo). To process
|
||
(e)plain TeX files, set the environment variable LATEX=tex.
|
||
|
||
In order to make texi2dvi a drop-in replacement of TeX/LaTeX in AUC-TeX,
|
||
the FILE may also be composed of the following simple TeX commands.
|
||
\`\\input{FILE}' the actual file to compile
|
||
\`\\nonstopmode' same as --batch
|
||
|
||
When invoked as \`texi2pdf' or \`pdftexi2dvi', or given the option --pdf
|
||
or --dvipdf, generate PDF output. Otherwise, generate DVI.
|
||
|
||
General options:
|
||
-b, --batch no interaction
|
||
-D, --debug turn on shell debugging (set -x)
|
||
-h, --help display this help and exit successfully
|
||
-o, --output=OFILE leave output in OFILE; only one input FILE is allowed
|
||
-q, --quiet no output unless errors (implies --batch)
|
||
-s, --silent same as --quiet
|
||
-v, --version display version information and exit successfully
|
||
-V, --verbose report on what is done
|
||
|
||
Output format:
|
||
--dvi output a DVI file [default]
|
||
--dvipdf output a PDF file via DVI (using a dvi-to-pdf program)
|
||
--html output an HTML file from LaTeX, using HeVeA
|
||
--info output an Info file from LaTeX, using HeVeA
|
||
-p, --pdf use pdftex or pdflatex for processing
|
||
--ps output a PostScript file via DVI (using dvips)
|
||
--text output a plain text file from LaTeX, using HeVeA
|
||
|
||
TeX tuning:
|
||
-@ use @input instead of \input for preloaded Texinfo
|
||
-e, -E, --expand force macro expansion using makeinfo
|
||
-I DIR search DIR for Texinfo files
|
||
-l, --language=LANG specify LANG for FILE, either latex or texinfo
|
||
--no-line-error do not pass --file-line-error to TeX
|
||
--shell-escape pass --shell-escape to TeX
|
||
--src-specials pass --src-specials to TeX
|
||
-t, --command=CMD insert CMD in copy of input file
|
||
or --texinfo=CMD multiple values accumulate
|
||
--translate-file=FILE use given charset translation file for TeX
|
||
|
||
Build modes:
|
||
--build=MODE specify the treatment of auxiliary files [$build_mode]
|
||
--tidy same as --build=tidy
|
||
-c, --clean same as --build=clean
|
||
--build-dir=DIR specify where the tidy compilation is performed;
|
||
implies --tidy;
|
||
defaults to TEXI2DVI_BUILD_DIRECTORY [$build_dir]
|
||
--mostly-clean remove the auxiliary files and directories
|
||
but not the output
|
||
--max-iterations=N don't process files more than N times [$max_iters]
|
||
|
||
The MODE specifies where the TeX compilation takes place, and, as a
|
||
consequence, how auxiliary files are treated. The build mode
|
||
can also be set using the environment variable TEXI2DVI_BUILD_MODE.
|
||
|
||
Valid MODEs are:
|
||
\`local' compile in the current directory, leaving all the auxiliary
|
||
files around. This is the traditional TeX use.
|
||
\`tidy' compile in a local *.t2d directory, where the auxiliary files
|
||
are left. Output files are copied back to the original file.
|
||
\`clean' same as \`tidy', but remove the auxiliary directory afterwards.
|
||
Every compilation therefore requires the full cycle.
|
||
|
||
Using the \`tidy' mode brings several advantages:
|
||
- the current directory is not cluttered with plethora of temporary files.
|
||
- clutter can be even further reduced using --build-dir=dir: all the *.t2d
|
||
directories are stored there.
|
||
- clutter can be reduced to zero using, e.g., --build-dir=/tmp/\$USER.t2d
|
||
or --build-dir=\$HOME/.t2d.
|
||
- the output file is updated after every successful TeX run, for
|
||
sake of concurrent visualization of the output. In a \`local' build
|
||
the viewer stops during the whole TeX run.
|
||
- if the compilation fails, the previous state of the output file
|
||
is preserved.
|
||
- PDF and DVI compilation are kept in separate subdirectories
|
||
preventing any possibility of auxiliary file incompatibility.
|
||
|
||
On the other hand, because \`tidy' compilation takes place in another
|
||
directory, occasionally TeX won't be able to find some files (e.g., when
|
||
using \\graphicspath): in that case, use -I to specify the additional
|
||
directories to consider.
|
||
|
||
The values of the BIBER, BIBTEX, DVIPDF, DVIPS, HEVEA, LATEX, MAKEINDEX,
|
||
MAKEINFO, PDFLATEX, PDFTEX, SED, T4HT, TEX, TEX4HT, TEXINDEX, and THUMBPDF_CMD
|
||
environment variables are used to run those commands, if they are set.
|
||
|
||
Regarding --dvipdf, if DVIPDF is not set in the environment, the
|
||
following programs are looked for (in this order): dvipdfmx dvipdfm
|
||
dvipdf dvi2pdf dvitopdf.
|
||
|
||
Any CMD strings are added after @setfilename for Texinfo input, or in
|
||
the first line for LaTeX input.
