2016-12-15Horner and helmert (#456)Thomas Knudsen
Introducing the Horner polynomial evaluator also introduces the need for very long +init:tag arguments (a n'th order 2D polynomium has (n+1)(n+2)/2 coefficients, and n is typically in the range 5-10, i.e. up to around 60 coefficients for each polynomium, and there are 4 polynomia in a complete back/forward transformation set). Hence, in this commit, along with the first part of the Horner code, the code for reading +init files has been modified in a (for all practical purposes) backwards compatible way, by making it possible to introduce line continuations by escaping line breaks, i.e. preceding them with a backslash. An escaped line break works (as it would in TeX), by skipping all following whitespace, including interspersed #-comments. This simple extension makes it possible to create very long initialization elements without losing track of the structure (cf. s45b.pol and pj_init_test.c in the examples-directory for a demo). The s45b.pol file was created by hand-editing the output of the software doing the original constrained adjustment for the polynomial coefficients. The simple adding of the “skip following whitespace and comments” feature has made it possible to retain almost all metadata from the source material. This is considered very important, since 1) For the lack of a prior common file format for geodetic polynomial coefficients, there is a good chance that this will become THE standard, at least for the time being, and 2) Without the metadata represented, it will be very hard for a human to debug code involving a slightly misrepresented polynomium. Due to the current architecture of the pj_init.c code (mostly around the fill_buffer() function), it is next to impossible to implement the line continuation functionality in full generality. Hence, it has been necessary to limit this format extension to files smaller than 64 kB. * Correction of spherical HEALpix test case The first HEALpix test case in nad/testvarious is clearly intended to invoke the spherical form of HEALpix. It does, however, specify the spheroid using the +a=1 size parameter, without specifying any shape parameter. But since +no_defs is not specified either, a shape parameter is picked up from the nad/proj_def.dat file (where ellps=WGS84 is given in the <general> section). It appears that this has not happened before I updated the pj_init code to support projection pipelines (see below). I do, however, believe that the present behaviour is the correct one, and rather than retrohacking the pj_init code, to (incorrectly, I believe) reproduce the prior behaviour, I have corrected the test case invocation in nad/testvarious to specify the spheroid using the +R=1 size parameter (which was already used in the following test case). * Repair scaling of projections stomping on value of semimajor axis * Workaround MSVC HUGE_VAL misimplementation. The "return const err object" idiom (i.e. const <type> err = {HUGE_VAL,...}; ... if (bad) return err) is problematic to implement due to MSVC's misimplementation of HUGE_VAL as a non-const. Hence, we need to run-time initialize these. In the pj_inv functions, this was mistakenly done to the wrong object. For pj_fwdobs/invobs and the remaining part of the obs-based API, this is now worked around by providing functions returning a run time HUGE_VAL initialized PJ_OBS or PJ_COO resp. Obnoxious, but given MSVC's market penetration there is really not much else we can do.

2016-11-20Plumbing for pipelines (#453)Thomas Knudsen
* re-enter pipeline The pipeline interface is now internally based on the pj_obs_api, which simplifies the implementation significantly. This is the first mock up - it compiles fine, but is currently untested * pipeline code cleaned up The pipeline code is now based on the PJ_OBS api (although you can still invoke a pipeline through pj_fwd/pj_inv and their 3D brethren). This has made it possible to eliminate scores of funky casts and convoluted workarounds. The code is now way more straightforward and mostly conforming with common C idioms.. Also, the proj.h / obs_api interface to the logging system has been streamlined through the introduction of the pj_log_error, pj_log_debug, and pj_log_trace functions. * Geodesics + minor changes First proj.h style interface to Charles Karney's geodesics code: pj_lp_dist. Also, renamed pj_apply -> pj_trans * Extended Ellipsoidal Parameters Second eccentricity, second and third flattening etc. * Rename pj_debug_set -> pj_log_level ... and add self test code for PJ_pipeline * Clean up missing pj_apply->pj_trans * Clean up missing pj_obs_dist_2d rename * pj_strerrno bug fixed. Some doc/comments added (In response to a review by @kbevers)

Need these to reduce the chance I'm screwing up something during this rather intrusive code surgery
2016-04-01First steps toward simplified macros/internalsThomas Knudsen
The brief version:: In an attempt to make proj.4 code slightly more secure and much easier to read and maintain, I'm trying to eliminate a few unfortunate design decisions from the early days of proj.4 The work will be *very* intrusive, especially in the PJ_xxx segment of the code tree, but great care has been taken to design a process that can be implemented stepwise and localized, one projection at a time, then finalized with a relatively small and concentrated work package. The (very) long version: See the comments in PJ_minimal.c
2015-07-07Make pj_init() locale safe and no longer modify locale (#226)Even Rouault
Remove setlocale() use in pj_init_ctx(), and replace uses of atof() & strtod() by their locale safe variants pj_atof() and pj_strtod(). Proj versions from now advertize #define PJ_LOCALE_SAFE 1 in proj_api.h and export pj_atof() & pj_strtod()
