2019-03-28[dune] Don't have `lib` depend on `dynlink`Emilio Jesus Gallego Arias

Instead of rolling our own, we use the standard one that works well when binaries are symlinked.
2018-09-05[bin] Fix binary location procedure to work with symlinks.Emilio Jesus Gallego Arias
In #7860 `Sys.executable_name` was introduced to locate coq private binaries; however, this breaks use cases with symlinks, such as Dune. In order to fix this, we adopt a simpler strategy; we will always adapt the name originally provided by the user, and only add a directory if it was originally present. This should work (hopefully) in all cases. This fixes `coqide` not working on Dune builds.
2018-06-22Fix #7704: get_toplevel_path needs normalised argv.(0)Gaëtan Gilbert
When launched through PATH argv.(0) is just the command name. eg "coqtop -compile foo.v" -> argv.(0) = "coqtop" Using executable_name also follows symlinks but this isn't tested to avoid messing with windows. Running Coq through a symlink is not as important as PATH anyways.
2018-05-21[stm] Make toplevels standalone executables.Emilio Jesus Gallego Arias
We turn coqtop "plugins" into standalone executables, which will be installed in `COQBIN` and located using the standard `PATH` mechanism. Using dynamic linking for `coqtop` customization didn't make a lot of sense, given that only one of such "plugins" could be loaded at a time. This cleans up some code and solves two problems: - `coqtop` needing to locate plugins, - dependency issues as plugins in `stm` depended on files in `toplevel`. In order to implement this, we do some minor cleanup of the toplevel API, making it functional, and implement uniform build rules. In particular: - `stm` and `toplevel` have become library-only directories, - a new directory, `topbin`, contains the new executables, - 4 new binaries have been introduced, for coqide and the stm. - we provide a common and cleaned up way to locate toplevels.

2017-10-06[stm] [flags] Move document mode flags to the STM.Emilio Jesus Gallego Arias
We move toplevel/STM flags from `Flags` to their proper components; this ensures that low-level code doesn't depend on them, which was incorrect and source of many problems wrt the interfaces. Lower-level components should not be aware whether they are running in batch or interactive mode, but instead provide a functional interface. In particular: == Added flags == - `Safe_typing.allow_delayed_constants` Allow delayed constants in the kernel. - `Flags.record_aux_file` Output `Proof using` information from the kernel. - `System.trust_file_cache` Assume that the file system won't change during our run. == Deleted flags == - `Flags.compilation_mode` - `Flags.batch_mode` Additionally, we modify the STM entry point and `coqtop` to account for the needed state. Note that testing may be necessary and the number of combinations possible exceeds what the test-suite / regular use does. The next step is to fix the initialization problems [c.f. Bugzilla], which will require a larger rework of the STM interface.
2017-09-13A possible fix for BZ#5715 (escape non-utf8 win32 file names).Hugo Herbelin
On Win32, Sys.readdir translates the file names to the charset of the local "code page", which may be not compatible with utf8. Warnings referring to these names can be generated. These warnings may be sent to CoqIDE. To ensure a utf8 compliant communication, we escape non-utf8 file names under win32. In the CoqIDE/Coq communication, Glib.IO.read_chars expects an utf8-encoding and raises otherwise a Glib.Error "Invalid byte sequence in conversion input". This fixes bug #5715 (Hangul characters not recognized in file names) but this does not solve the case of an operating system mounting a file system with a different coding convention than the default one, i.e. unicode using "Normalization Form Canonical Decomposition" in UTF-8 for HFS+ on MacOS X, no encoding for ext3/ext4 on Linux, (non-normalized?) UTF-16 for NTFS on Windows.

2016-06-29A new infrastructure for warnings.Maxime Dénès
On the user side, coqtop and coqc take a list of warning names or categories after -w. No prefix means activate the warning, a "-" prefix means deactivate it, and "+" means turn the warning into an error. Special categories include "all", and "default" which contains the warnings enabled by default. We also provide a vernacular Set Warnings which takes the same flags as argument. Note that coqc now prints warnings. The name and category of a warning are printed with the warning itself. On the developer side, Feedback.msg_warning is still accessible, but the recommended way to print a warning is in two steps: 1) create it by: let warn_my_warning = CWarnings.create ~name:"my-warning" ~category:"my-category" (fun args -> Pp.strbrk ...) 2) print it by: warn_my_warning args

Coqdep_boot has almost no dependencies, and hence can be compiled very early during the build, without relying on .ml.d files. Some code of system.ml is now in a separate file minisys.ml, which is also included in system.ml for compatibility.
2016-05-31Feedback cleanupEmilio Jesus Gallego Arias
This patch splits pretty printing representation from IO operations. - `Pp` is kept in charge of the abstract pretty printing representation. - The `Feedback` module provides interface for doing printing IO. The patch continues work initiated for 8.5 and has the following effects: - The following functions in `Pp`: `pp`, `ppnl`, `pperr`, `pperrnl`, `pperr_flush`, `pp_flush`, `flush_all`, `msg`, `msgnl`, `msgerr`, `msgerrnl`, `message` are removed. `Feedback.msg_*` functions must be used instead. - Feedback provides different backends to handle output, currently, `stdout`, `emacs` and CoqIDE backends are provided. - Clients cannot specify flush policy anymore, thus `pp_flush` et al are gone. - `Feedback.feedback` takes an `edit_or_state_id` instead of the old mix. Lightly tested: Test-suite passes, Proof General and CoqIDE seem to work.

2015-12-21Trust the directory cache in batch mode.Guillaume Melquiond
When coqtop is a long-lived process (e.g. coqide), the user might be creating files on the fly. So we have to ask the operating system whether a file exists beforehand, so that we know whether the content of the directory cache is outdated. In batch mode, we can assume that the cache is always up-to-date, so we don't need to query the operating system before trusting the content of the cache. On a script doing "Require Import Reals", this brings down the number of stat syscalls from 42k to 2k. The number of syscalls could be further halved if all_subdirs was filling the directory cache.

2015-11-25Fix for case-insensitive path looking continued (#2554): Adding aHugo Herbelin
second chance to dynamically regenerate the file system cache when a file is not found (suggested by Guillaume M.).
2015-11-25Generalizing the patch to bug #2554 on fixing path looking withHugo Herbelin
correct case on MacOS X whose file system is case-insensitive but case-preserving (HFS+ configured in case-insensitive mode). Generalized it to any case-preserving case-insensitive file system, which makes it applicable to Windows with NTFS used in case-insensitive mode but also to Linux when mounting a case-insensitive file system. Removed the blow-up of the patch, improved the core of the patch by checking whether the case is correct only for the suffix part of the file to be found (not for the part which corresponds to the path in which where to look), and finally used a cache so that the effect of the patch is not observable. Note that the cache is implemented in a way not synchronous with backtracking what implies e.g. that a file compiled in the middle of an interactive session would not be found until Coq is restarted, even by backtracking before the corresponding Require.

This patch causes a bit of code duplication (because of the .coq suffix added to state files) but it makes it clear which part of the code is looking up files in the loadpath and for what purpose. Also it makes the interface of System.extern_intern and System.raw_extern_intern much saner.
